Your Android phone is your everyday companion, so you notice when it’s not holding a charge as long as it used to. You’re starting to wonder if there’s a problem with the battery. That means it’s time to do a little sleuthing.

To become a battery detective, you’ll need to know where to look for clues and what apps can help you out as you investigate your smartphone. RELATED: Apps to get the most from your Android device.

It used to be easy to replace a cellphone battery, but newer phones make this difficult. If your battery is a lost cause, you’ll need to check your warranty status and look into repair or replacement options. But first, here’s how to find out if your battery has gone bad.

Notice the symptoms of a failing battery

Battery performance can deteriorate as a phone ages. The initial signs of battery issues may start off as subtle hints before becoming too much to overlook. It’s time to check your battery if you experience some or all of these symptoms:

It doesn’t last: It used to be you could charge your phone overnight, use it all day long, and still have some juice left at bedtime. But now you’re looking for an outlet in the afternoon and carrying a portable battery backup to get through the day.

Tech news that matters to you, daily

Privacy, security, the latest trends and the info you need to live your best digital life.

Battery charge drops rapidly: You unplug your phone, confident in a full charge, only to see it drop quickly even though you’re not doing anything unusual.

It doesn’t fully charge: You leave your phone plugged in for hours, but it never gets back up to a full charge. Something is definitely up.

There are physical symptoms: You notice your phone is off-the-charts hot when charging, or you may even notice a physical bulge on the phone. Unplug it right away if this happens.

Check for problem apps

How to monitor your android device’s battery health

Before you take the step of replacing a battery, head into Settings and tap on Battery. Give the usage details a quick glance and check which apps are using the most battery.

What you’re looking for is any unusual draining attributed to an app. If you notice a particular app is sucking up all your battery, especially if it’s an app you don’t use much, then you might try removing that app and seeing if your battery problems improve.

Check your battery health

Now it’s time to do a more thorough check-up on your battery. There are several apps in the Google Play Store designed to monitor battery health. AccuBattery is a good one to start with. Once you install the app and go through the initial setup, you’ll need to use your phone as usual while it monitors your battery.

How to monitor your android device’s battery health

Take some time to read through AccuBattery’s introduction. It has some suggestions for ways to approach battery charging, but what we’re really here for is the diagnostics. The longer you use the app, the more data it collects and the more accurate the battery information will be.

Once you’ve used the phone for at least a few days with the app installed, open AccuBattery and check the Health section. This will give you an idea of what sort of shape your battery is in compared to when it was new. If you’re seeing a poor battery health rating, then it’s probably time to look into replacing your battery or resigning yourself to carrying a portable battery backup when you know you’ll be away from an outlet.

Fixing a bad battery

If your phone is still under warranty, then contact customer service about a battery replacement. If not, you can check with a local repair shop about the price of a replacement. Just be sure to read up on the shop’s reviews and find out if the work comes with a guarantee or warranty for the new battery.

If you’re handy with electronics and don’t mind the potential risks of a DIY repair (bricking your phone, loss of waterproofing), you can check into the availability of a replacement battery kit. Amazon is a good place to start. Check the seller’s reviews and the reviews for the battery itself.

Also, check if iFixit has a repair guide available for your particular phone. It will tell you how difficult the job is and walk you through the process step by step.

One more thing to keep in mind: with so many solid and affordable Android phones on the market, you’ll need to decide if repair is a better option than replacement. If you choose to get a new phone, then be sure to check out our Komando guide on how to recycle your old one.

Almost all smartphones available in the market use lithium batteries. The issue with these batteries is that they degrade over time, affecting both the charge capacity and the recharge cycle. Now, while Android offers a lot of information regarding battery usage, there’s absolutely no native way to check battery degradation. Anyway, in this article, we’ll tell you some easy ways to check your Android phone’s battery health. Read on.

Check Android Phone’s Battery Health or Degradation Level

Using Dial Pad Codes

How to monitor your android device’s battery health

Some Android phones do let you check the battery health using hidden menus. OnePlus lets you check the same using its Diagnostic app- we’ve done a detailed post on it here.

Anyway, the most common code to check battery information across Android devices is *#*#4636#*#*. Type the code in your phone’s dialer and select the ‘Battery Information‘ menu to see your battery status.

If there’s no issue with the battery, it’ll show battery health as ‘good.’ You can also see and monitor the battery’s temperature here. The range of 30-40 degrees celsius is an ideal idle temperature for a phone kept at room temperature.

Using AccuBattery

The above method gives you only a vague idea of battery health. To get an estimate in numbers, you can use a third-party app called AccuBattery.

How to monitor your android device’s battery health

All you need to do is install AccuBattery from Play Store, set up the app, make sure the shown battery design capacity is correct, and leave it for a few days. Don’t forget to add the app to the “do not optimize list” to prevent it from being killed.

As you complete a few charging cycles, the app will start showing an estimate of your current battery capacity in the ‘Health’ tab. This number will keep getting accurate over the course of charging sessions.

Usually, the app will show 95% health for a brand new battery. And hence, you should consider that margin while figuring out how’s your battery at the moment. Anything above 80% is considered good provided that the phone aged well. You can opt for a battery replacement when it slips to the 70s, and you start feeling the loss in capacity.

How does AccuBattery work? Is it Accurate?

AccuBattery is merely an app, and no, it doesn’t have any magical powers to find your battery health. All it does is analyze your phone’s software and hardware battery usage to get an estimate of your phone’s current capacity.

It also keeps a record of daily wear and tear caused by charging cycles. Of course, charging the battery, too, causes degradation.

AccuBattery isn’t 100% accurate as it doesn’t have direct readings of the battery on a system level. When I got myself a brand new battery- the app analyzed it to have an estimated 95% health against its typical 4,200mAh capacity. So, do keep a 5% margin while counting the current battery health.

Moreover, it gives you other useful stats like battery charging and discharging speeds per hour, temperature, battery wear per charge cycle, and charging and discharging history. You can also set the alarm to notify when the battery gets charged to 80%.

Tips To Prevent Android Phone’s Battery Degradation

How to monitor your android device’s battery health

Battery degradation is inevitable and it’ll eventually happen over the course of time. However, you can follow the useful tips below to prolong the good battery health on your phone.

  • Avoid extreme levels like charging to 100% or discharging all the way to 0%.
  • Try to keep the battery in the 40-80% zone. Frequent, small top-ups are better than full recharges.
  • Avoid fast charging if you’re not in a hurry.
  • Keep the phone in a cool ambiance, especially while charging. Please don’t use it while plugged in.
  • Use these battery-saving tips whenever possible. Less drainage = fewer recharges.
  • Use original charger and cable or at least a certified third-party charger with the same specification.
  • While phones do stop charging at 100%, you should still avoid overnight charging.
  • If you’re storing the phone for long-term, charge the battery to 50% instead of 100%.

Wrapping Up

So this was all about how you can check your Android phone’s battery health or degradation. We’ve also mentioned a few tips to prevent battery degradation and prolong the health of your phone. Anyway, what’s the status of your phone’s battery? Do let me know in the comments below.

Smartphone battery health has always been an issue. However, since the whole iPhone slowdown fiasco, it has been highlighted more than ever. Android smartphones don’t have similar slow-downs, not due to the battery at least. However, it is still a good idea to check battery health on Android devices.

For one, it tells you what the battery capacity used to be and what it is at the moment. Thus, it gives you a better idea of what to expect.

Can You Check Battery Health On Android

The problem is that unlike iPhones, Android battery stats don’t show the battery health. Now, something of that sort may appear in the final build of Android 11, or 12 or some time in the future. But as of Android 10, in 2020, Android does not show battery health in Settings. You can see other battery stats and related features in Settings > Battery. You can also tap on the three-dot menu button to see Battery usage.

How to monitor your android device’s battery health

While you can’t quite check battery health, you can see which apps are affecting battery life the most.

Like a lot of other things on Android, however, if Google doesn’t do it, third-party apps can. But there’s also another way through dialer codes. Although, this does not work on many devices and is therefore not a consistent method.

Check Battery Capacity On Android Using Dialer Code

Android has a lot of hidden dialer codes. These codes are meant for developers or service staff. These provide easy access to information that the end-user might not need. On some devices, you can also check battery health with a dialer code.

  1. On your phone, launch the dialer app and dial *#*#4636#*#*
  2. As soon as you do, you will be taken to the Testing menu.

How to monitor your android device’s battery health

Unfortunately, on our Pixel 3a, there was no battery information available. But your mileage may vary depending upon the make and build of your device.

Check Battery Health On Android With AccuBattery

There are many apps on the Play Store that can provide you the desired information. But most of them are either ridden with ads or seem shady. AccuBattery is one of the most highly-rated apps for gaining additional battery information. If you have a rooted Android device, you may find a better app that provides even more info. For the average non-rooted Android user though AccuBattery provides more than enough information.

It’s worth noting that the app does a lot more than just gauging your device’s battery health. However, that’s all we’ll be focusing on here.

  1. Download and install the AccuBattery on Google Play Store. The link is provided below.
  2. Launch the app and go through the quick walkthrough.
  3. During the walkthrough, you will come across a page that talks about battery health.
  4. Since that’s what we’re talking about today, you might want to pay attention to this page.
  5. The following page also lets you set a charge slider that notifies you when the battery hits that percentage.How to monitor your android device’s battery health
  6. It’s set at 80 by default which is universally accepted as the best limit to charge your battery.
  7. Finally, the app runs a quick calibration of your battery and detects the stock battery capacity.How to monitor your android device’s battery health
  8. You can see the usual battery stats you would find in the battery usage page in Settings.
  9. Switch to the Health tab.

How to monitor your android device’s battery healthHere, you can find information about the Battery health of your Android, current capacity, and original capacity. There are also charts showing battery wear.

As you’ll notice, at this point this screen is just full of blanks. That’s because the app has no information to provide yet. Android does not provide historical information about your app or battery usage to other apps. Therefore, AccuBattery will have to start from scratch. Over time the app will track your battery wear and battery capacity of your Android. Similarly, the other numbers will also be populated over time.

Battery Health On Android Devices

Before smartphones, batteries in mobile phones weren’t really a big deal. Phones used to last several days on a single charge. But when smartphones happened, battery-life took a real hit. Early smartphones couldn’t even get through a day without needing a top-up charge. Most smartphones still need to be charged once a day. This makes the battery health deteriorate faster. Keeping tabs on the battery health is never a bad idea.

OnePlus, like most other Android device makers, doesn’t offer removable batteries on their smartphones. On a journey to make its smartphones slim as well as dust and water resistant, OnePlus made it really hard for a novice to swap out an older degraded battery for a new one without paying a visit to a service center. However, the company does have a really handy diagnostic app that can give users a clear insight into the health of their battery.

The app is called “OnePlus Diagnostic” with the package name com.oneplus.healthcheck , which comes as no surprise. Community members of XDA have been aware of this app for quite a long time as OnePlus itself published it on their Chinese support site. The app is compatible with both HydrogenOS and OxygenOS, and you can easily take a look at important battery parameters (e.g. capacity, temperature, charging state, etc.) through its clean and clutter-free UI. The screenshots attached below are from XDA Senior Member Some_Random_Username‘s OnePlus 5T which he purchased in December of 2017. The OnePlus 5T supports 20W Dash Charging.

The value of the “Battery state” parameter is particularly appealing because it shows the battery wear level. Upon inspecting the app’s code, we discovered that the app reads the value from /sys/class/power_supply/bms/battery_health . Here “bms” stands for Battery Management System, while this value is reported by a battery fuel gauge IC made by Maxim Integrated. If that value is /sys/class/power_supply/bms/battery_health . If you have a rooted phone, though, you can manually check that value by running the following command in a rooted shell or any terminal emulator app running in elevated mode:

It is worth noting that this diagnostic app is different from the hidden suite of hardware diagnostic tests, also known as “Engineer Mode”. In case you want to give OnePlus Diagnostic a try to find out about the battery health of your phone, download the APK from the following link:

There is a number of factors that contribute to poor battery life on your Android phone.

The tasks today’s smartphones perform are more demanding than ever. And to accommodate growing needs, processors have become more powerful and screens have gotten larger.

How to monitor your android device’s battery healthSmartphone charging via cable in a car

We’re starting to expect more and more out of our devices every year, but developments in battery longevity haven’t kept the pace.

Each manufacturer uses a different version of the operating system, so certain settings and features are going to look different.

Here are some practical tips for improving the battery life on an Android phone.

Turn Off Automatic Wi-Fi

Since the Oreo update, Android comes with a feature that continues to look for open Wi-Fi networks even when you’ve disabled Wi-Fi. To turn it off, open Settings > Network & internet > Wi-Fi. Under Wi-Fi preferences, uncheck the Turn on Wi-Fi automatically option.

Switch to the Dark Side

Since OLED displays can disable individual pixels, backgrounds with deep blacks allow them to consume less power.

You can take advantage of this in many ways. You can begin by applying a dark wallpaper, enabling a system-wide dark theme and more.

Take Control of Your Apps

How to monitor your android device’s battery health

Developers put a lot of work into making sure their apps run as efficiently as possible, but many will continue to run in the background even when you aren’t using them. This will, of course, eat up data and battery life over time. You can put unused apps to sleep under the App Power Management option in the device care section of your phone.

Monitor Misbehaving Apps

Your battery life can take a big hit if an app doesn’t work as it’s supposed to. This could be caused by anything from a bug to a deliberate aggressive background feature. You can check this by heading into Settings > Battery > Menu > Battery Usage to see which apps have drained the most of it.

Check your location services settings

How to monitor your android device’s battery health

Some apps like Google Maps require you to turn on location services to display your surroundings and give you directions. But location services chip away at your battery life very quickly, and you should turn it on only for as long as you need to.

Disable Google Assistant

Google is always on. It’s listening for the wake command, is connected to your location for instantly fetching contextual results, and more. If you don’t heavily depend on Google Assistant, it’s best to shutter it.

Configure the sleep schedule

How to monitor your android device’s battery health

You can configure your phone to enjoy a peaceful sleep by switching off the optional features automatically. These include mobile data and location and sync services. Since they drain your phone’s battery, it helps to save some juice as well.

Some phones have options like Auto-Sleep, Battery-saver, and Do Not Disturb, which you can enable to turn off those settings at night.

How to monitor your android device’s battery health

The more powerful the phone, the more things it can do. Unfortunately, the more things a phone can do, the faster its battery will drain. You can’t expect a person to multitask and not get tired, after all. It’s easy to abuse our phones. When you have a powerful processor and a lot of storage space available, it’s pretty hard not to install and use a lot of apps at one time. Though theoretically a device can last, say, up to 12 hours, you might find it kicking the bucket at only 8. It isn’t a device malfunction, but it’s the way you’re burning through your battery power. What’s an Android user to do when she or he has to stretch the phone’s life to more than 8 hours? Why, see the doctor for a diagnosis, of course.

In this case, the Battery Doctor is an excellent and comprehensive battery health app that will give you an idea of how you’re using your phone and ways to extend its life. This one app certainly got through medical school because it’s extremely comprehensive.

How to monitor your android device’s battery health

When you launch the app, you’ll immediately notice its clean interface. You start out on the Saver tab which shows you how much battery life you have left in the top portion of the screen. The lower half of the screen shows you the various functions you’re currently using and how much battery life you can save when you disable them. Syncing, for example, eats up 76 minutes of your battery life. Tap on Sync to disable it and you’ve just saved yourself 76 minutes. You can turn off other functions too, such as Wi-Fi, Data, adjust Brightness, toggle GPS, Bluetooth, Touch and toggle between Vibrate, Mute, and various levels of Volume.

How to monitor your android device’s battery health

The next tab is Charge, which shows you how long you should charge your phone to get it back to full power. Battery Doctor will also rate your charging habits and will give you some charging advice. You might also see the little calendar icon on the upper right corner of the screen.

How to monitor your android device’s battery health

Tap on it and you’ll see the dates when you charged your device. If you’ve just installed Battery Doctor, don’t be surprised to not find anything there. Battery Doctor will only start monitoring when you charge after installation.

How to monitor your android device’s battery health

When you’re charging, Battery Doctor gives you an extra something. Tap on the little pull tab on the right side of the screen to get a special lock screen. It’ll show you your battery level, its status (a la electrocardiogram) and how much time you have left until it’s fully charged. Though this lock screen isn’t a real one and can be easily exited by hitting your device’s Home button, it’s still a very nice touch.

The Consume tab shows you the top 10 apps you have that consume your battery life. Tap on an app and you can easily uninstall the battery vampire.

Battery Doctor gives you a small battery percentage indicator on your taskbar. It’s surrounded by a green ring when it’s in good health but when it’s in the mid-range, it’ll be in yellow. That way you can just glance at your screen quickly to assess your battery situation.

The app is available for free and to my great surprise, not a single ad was present in the app. Give your device’s battery a check up with Battery Doctor today.

As much as we love our technology, it has its limits. Just like we only have so much energy to go run a marathon (who am I kidding, I don’t run, I look like Jabba the Hutt), phones burn through a finite amount of energy resources used by apps before we need to fill them back up with juice.

There are a lot of battery testing resources when it comes to Android application testing. There’s even a native battery analyzer that’s built into Android’s OS. Thankfully, there are also several apps in the Google Play store that’ll help narrow down your app’s battery usage. We’ve narrowed it down to some of our favorites. We also cover a sample battery testing cycle and suggest possibilities as to why your app might be using too much power.

Note that none of these requires root access, which is, for the intents and purposes of testing, just fine – most of your user base probably haven’t rooted their phones.

How to monitor your android device’s battery health

Android’s Built-In Battery App

The native battery analyzer can analyze each application and identify the one that’s gulping down the most juice, which is immensely useful right out the gate. All Android builds have a native battery analyzer (accessible by going to Settings > Device > Battery). One of the most practical benefits of the native battery analyzer is its ubiquity; it comes preinstalled on all Android devices. If your test phone library has, say, 20 phones, you won’t have to install it individually on each phone.

When you open this UI, you’ll see the charge amount, a list of your apps with a percentage of battery usage, and a time frame in days, hours, minutes, and seconds. For example 1d 9h 11m 7s.

This functionality can give you some useful information, but it’s difficult to focus on your app at the precise moment you’re targeting because to reset the stats, you have to charge fully to 100% and then unplug the device. Doing that in a test cycle can be time-consuming, although the stats hold up for accuracy if you have the time.

GSam Battery Monitor

Unlike the native Android battery analyzer, the GSam Battery Monitor can reset testing cycles on the fly, which means you don’t have to drain and recharge the battery to do your application’s power monitoring.

How to monitor your android device’s battery health

Battery usage settings you can monitor include: App power usage since the phone was last unplugged, app power usage since the phone’s last full charge, and app power usage since the screen was last shut off. The most useful part about these features is that you don’t have to wait to fully charge to get an information reset, and the GSam Battery Monitor can also tell you which functions of your app cause the most battery use.

Another helpful feature is that you can export your app’s analysis and send it via email, making it easy to import the information into project management software. Your product manager will breathe a little easier with all your development data in one place.

Clean Master

Clean Master is another battery testing app with a particularly useful function: notifications. It’ll let you know if an app is battering (pun intended) the phone’s CPU or battery. Knowing that you’ll be notified with battery or CPU usage problems on the fly will give you more time to focus on other testing issues in the meantime.

While CPU usage issues don’t necessarily have a direct correlation on battery use, the CPU Cooler in Clean Master’s Tools section is handy regardless. This will show if your app is overusing the CPU in any fashion. This tool can help you hunt down problems with the overall performance of your app, such as code or design issues.

How to monitor your android device’s battery health

Examples of Application Functions That Might Tax Battery

Ask yourself these questions if you’re concerned about potential battery abuse:

  • Does your app handle large amounts of data to/from it? An example: Can users export or import a large file such as photos or video?
  • Does your application handle streaming?
  • Does your application do a lot of location checking?
  • Does your app send analytic data from your app to a 3rd party like Google Analytics?
  • Does your app frequently sync between the user and a server?
  • Does your app use excessive wakelocks (when your app keeps the phone awake to send or receive data from your server – or another function)?

We recommend you run Clean Master to monitor battery usage spikes just in case of any anomalies.

How to Perform Battery Testing

Battery testing is something you’ll need to do in a methodical way. While every application is different, we’ve come up with an example of a mobile app testing workflow.

  • Set your phone/app up for the test (get ready to sync, or get ready to download/export/stream, etc).
  • Note your current battery stats (overall percentage, percentage used by your app currently, etc).
  • Perform the test.
  • Note the new battery stats. Keep a log of this data for comparison purposes.
  • Repeat testing for any features/functions that could potentially be problematic.
  • Do this testing with varying levels of overall battery (low/half/full), noting any differences along the way.
  • Confirm that your app’s other features/functions are working properly. For example, if your user turns off location checking in an application that needs geographic information, what happens to battery usage?

When it comes down to testing your app’s battery usage, using different angles of attack is the best approach. Each of these monitoring services we mentioned will help you get a better fix on what you need to improve upon, and with mobile apps, it’s all about efficiency.

Some phones have options like Auto-Sleep, Battery-saver, and Do Not Disturb, which you can enable to turn off those settings at night.

The iPhone has a feature that lets you see how much juice is left in your Bluetooth headphones, but most Android phones are lacking this ability. Thankfully, there’s a simple app that’ll close this gap in functionality.

To be clear, some custom ROMs and manufacturer-skinned versions of Android display a Bluetooth battery meter, but the feature is not included in AOSP, so it’s up to the manufacturer or custom ROM developer to implement. So if your phone doesn’t tell you how much life is left in your Bluetooth accessories, an app from developer limitium has you covered, and I’ll show you how it works below.

Requirements

  • Android 4.3 or higher
  • Bluetooth accessory that supports battery life reporting

Step 1: Install BatON

To get this one going, start by installing limitium’s app, which is called BatON. To do that, you can either search the Google Play Store, or just tap the following link from your Android device.

How to monitor your android device’s battery health

Step 2: Adjust Settings

Next, open the app, then grant the location permission if requested (this is required for the app to be able to scan Bluetooth devices). From there, head to the side navigation menu and take a quick trip to BatON’s settings page.

After that, back out one level and check out the Auto measure section. By tapping the “Measure frequency” option here, you can change how frequently BatON checks for a battery percentage update from your Bluetooth accessories. Note that while a higher frequency provides more up-to-the-minute stats, it will also result in slightly more battery drain for both your phone and the accessory.

Step 3: See Battery Life for Paired Bluetooth Devices

Once you’ve got everything configured to your liking, you’re all set. From now on, whenever a supported Bluetooth device is connected to your phone, you can simply open the BatON app to check its battery level. Depending on your settings, you can also see the battery level from any screen by checking your notification shade.

Note that not all Bluetooth accessories will report their battery percentage, and this is particularly true of older and lower-end products. On top of that, some accessories will only report certain ranges — like 20%, 50%, and 100% — meaning that they’ll stay on one percentage until they reach the next threshold.

So how are you liking your new Bluetooth battery meter? Let us know in the comment section below.
