Apple released iOS 8.1 on Monday, October 20 with a number of bug fixes, improvements and new features. iOS 8.1 also addressed one of the major annoyances for users in some countries where there is still poor 3G or 4G LTE coverage by giving users an option to switch to 2G, 3G or LTE.
Since there are still quite a few areas in some countries that have poor 3G coverage, iPhone users who lived in such areas used to disable 3G to extend their iPhone’s battery life, and relied on the slower 2G (EDGE) connection, which was possible in iOS 7 or earlier. So they were annoyed when the option to disable 3G was not present after upgrading to iOS 8.
As mentioned in the release notes, Apple has added an option to select between 2G, 3G or LTE for cellular data. It’s quite simple, here’s how to switch to 2G, 3G or LTE for cellular data:
Note: This option is available only in iOS 8.1 or higher.
- Launch the Settings app.
- Tap on Cellular/Mobile.
- Then tap on Voice & Data.
- Tap on either LTE, 3G or 2G from the list of options.
That’s it. Your iPhone should now use the appropriate mobile speed for cellular data.
We’ve received quite a few complaints from our readers that they’re not seeing the Voice & Data option. I’m not sure why exactly everyone is not seeing this option. This could be related to your carrier. You may want to check if there are any new Carrier Settings that you need to download to address the issue.
Update Carrier Settings
To manually check if a new Carrier Settings is available for download, connection your iPhone running iOS 8.1 to the computer, launch iTunes and click on the “Check of Updates”. If there is a new Carrier Settings, then you should get the following popup informing you that “An update to the carrier settings for your iPhone is available”. Click on Download and Update button to install the new carrier settings.
You should get an option to update carrier settings automatically, but you can check it manually like this. If you’ve the latest carrier settings, then you’ll get a message telling you that “This version of the iPhone software is the current version.”
If that doesn’t help then you may want to contact your carrier to find out how to fix the issue. You can find the version number of the carrier settings in the Settings app (Settings > About > Version).
Nesvarbu, ar jūs gyvenate kažkur be 4G aprėpties, gyvenate blogoje aprėpties zonoje, ar tiesiog norite išlaikyti baterijos veikimo trukmę, itin paprasta 4G / LTE išjungti naują trečiosios kartos "iPad" ir vietoj to perjungti į 3G, kuriame naudojama mažiau baterijos gyvenimas.
Pastaba: Mes dar nepadarėme oficialių bandymų, kad išsiaiškintume, kiek baterijos galėtumėte sutaupyti, tačiau nėra abejonių, kad 4G LTE technologija naudoja daug daugiau akumuliatorių, ir naudinga žinoti, kad galite ją išjungti.
Kaip išjungti 4G iPad
Eikite į "Nustatymai" -> "Mobilieji duomenys" ir įjunkite "LTE" iš "Įjungta" į "Išjungta". Kai tik tai atliksite, matysite LTE viršutinėje juostoje, o ne 3G.
Žinoma, jei jūs sėdite aplink savo namuose su Wi-Fi įjungta, visai nėra jokios priežasties G, taigi jūs taip pat galite perjungti "Cellular Data".
Atkreipkite dėmesį, kad prabudimas iš mobiliųjų duomenų namuose turėtų teoriškai įsitikinti, kad naudojate mažiau duomenų iš savo plano.
Bez ohľadu na to, či žijete niekde bez pokrytia 4G, žijete v zlom pokrytom pásme alebo chcete len šetriť životnosť batérie, je veľmi jednoduché vypnúť 4G / LTE na novej generácii iPad tretej generácie a prepnúť na 3G, life.
Poznámka: Ešte sme nevykonali formálne testovanie, aby sme zistili, koľko batérie by ste mohli ušetriť, ale nie je pochýb o tom, že technológia 4G LTE využíva oveľa viac batérie celkovo a je užitočné vedieť, že ju môžete vypnúť.
Ako zakázať 4G na iPad
Prejdite do sekcie Nastavenia -> Mobilné dáta a prepnite možnosť Zapnúť LTE z Zapnuté na Vypnuté. Akonáhle to učiníte, uvidíte, že LTE v hornom paneli sa namiesto toho zmení na 3G.
Samozrejme, ak sedíte vo svojom dome s Wi-Fi povoleným, nie je žiadny dôvod pre žiadny G vôbec, takže môžete vypnúť aj Cellular Data.
Všimnite si, že odkláňanie bunkových dát doma by sa teoreticky malo ubezpečiť, že používate menej údajov z vášho plánu.
Akár 4G lefedettség nélkül élsz, rossz fedett zónában élsz, vagy csak meg akarod tartani az akkumulátor élettartamát, rendkívül egyszerű letiltani a 4G / LTE-t az új 3. generációs iPaden, és helyettesíteni a 3G-et, amely kevesebb akkumulátort használ élet.
Jegyzet: Még nem végeztünk hivatalos tesztelést, hogy kiderítsük, mennyi energiát takaríthat meg, de nem kérdéses, hogy a 4G LTE technológia sokkal több akkumulátort használ-e, és hasznos tudni, hogy letilthatja.
Hogyan lehet letiltani 4G az iPad
Ugrás a Beállítások -> Mobiladat és kapcsoló Kapcsolja be az LTE-t On-ra Ki. Amint ez megtörtént, az LTE a felső sávban vált át 3G-re.
Természetesen, ha Wi-Fi-vel engedélyezve van a háza körül, akkor semmi sem indokolja a G-t, így a Cellular Data is lefordítható.
Felhívjuk a figyelmet arra, hogy a mobiladatok otthoni kikapcsolása elméletileg gondoskodjon róla, hogy kevésbé használja a tervadatait.
iPhone users now have the ability to choose their desired maximum cellular data speed from available options. This data speed toggle was added to the iPhone with iOS 8.1 and is not yet available on all carriers, but for those that do support the data choice feature it’s quite easy to use.
As mentioned before, users must be on iOS 8.1 (or newer if you’re really special), and not all iPhones are going to have this option available within the Settings app, it’s ultimately dependent on the cellular carrier to allow users to switch their data speed. Users may want to connect your iPhone to a computer with iTunes 12 (or newer) before trying this to see if there is a carrier settings update available through iTunes which could enable it. If all else fails, you could always contact your cell plan provider directly and ask about the feature too.
- Open the Settings app on the iPhone and go to “Cellular” (sometimes labeled “Mobile” for other carriers)
- Tap on “Voice & Data”
- Choose your desired cellular data speed from the following options:
- LTE – the fastest cellular data service available, but can reduce battery performance
- 3G / 4G – moderate speed cellular data transmission
- 2G / Edge – very slow cellular data, largely unusable for anything beyond transferring small amounts of text and data
- Tap back onto “Cellular” and exit out of Settings to set the change
Remember, whatever you choose is the maximum speed, not necessarily a guarantee that your iPhone will always use that chosen cellular connection speed. Thus, even if you choose LTE, you still may cycle down to 3G or 2G if the connected cell tower only supports those speeds. On the other hand, choosing something like 3G will cycle down to 2G, but will never cycle up to LTE.
For most users, they’ll want to stay with LTE as the default choice, since it tends to provide the best experience for speed and usability for iPhone. Switching down to a lower cellular service can offer a way to increase battery life though, though by no means should the addition of this feature in iOS 8.1 impact battery life in any way.
It’s not entirely clear what carriers support the feature and what carriers don’t, but it’s pretty easy to find out if your iPhone is one of them. For those that don’t allow a cellular speed option, tapping on “Voice & Data” will reveal a simpler list of options: Off, Voice & Data (the default), or Data Only. This includes AT&T and T-Mobile in the USA, though it’s uncertain of Verizon or Sprint support either, and it may actually be dependent on individual data plans. Many global carriers do have the option, however.
Apple claims that with normal use (web browsing, watching videos, playing music, etc.) the battery life can reach nine to ten hours for an iPad. Obviously, if you’re using your tablet for heavier activities you also end up using more juice. But there are some tricks to saving more iPad battery life. These will surely come in handy, especially when you need to finish a task on your iPad and are in danger of losing power.
1. Activate Auto-Brightness
According to Apple one of the simplest ways to preserve iPad battery is by adjusting screen brightness. By turning on the Auto-Brightness feature of your tab, the screen will automatically adjust to the ambient brightness in a room. This means your tablet will automatically dim when you’re using it in dim places. To activate, go to Settings > Display & Brightness > Auto-Brightness, and turn on.
2. Manually adjust brightness
Even when your iPad has automatically adjusted the screen brightness, it can still be too bright for some. Go to Settings > Display & Brightness > Brightness and adjust the level there. Or an easier way is to open your Control Center and use the slider to decrease the brightness. Using the right amount of brightness not only saves iPad battery life, it also helps you avoid eye strain.
3. Close all wireless technologies when not in use
Wi-Fi consumes less power than a cellular connection, so it’s better to use it whenever you can. However, it can hog your iPad battery life even when you’re not connected to a network. So it’s better to turn it off when you don’t need the Internet. Bluetooth and Airdrop also suck up battery juice when they’re turned on, even when you’re not connecting to or sharing files between other devices. Turn them off also when not in use.
4. Turn off Location Services
This GPS functionality of your iPad is another form of wireless technology. When this isn’t disabled, apps will continue to use your location even when you aren’t using them. If you don’t need driving directions at the moment, switch this off by going to Settings > Privacy > Location Services. If you don’t want to completely disable it, just choose which apps can use this function.
5. Disable 4G or 3G
Some iPads have built-in 3G or 4G LTE data connection. This drains power when enabled, even when you’re not using the Internet. So save some juice by going to Settings > Cellular > Cellular Data, and turning the 4G or 3G connection off.
6. Use Auto-Lock
Your iPad is still sucking up battery life even when it’s idle. By activating Auto-Lock, your tab can automatically shut down when it has been inactive for a certain period of time. Go to Settings > Display & Brightness > Auto-Lock. Then choose which interval you prefer. Try to keep it to the lowest option that won’t cause you any inconvenience while using your tablet.
7. Deactivate Push, Fetch, and Handoff
The Push and Fetch feature will automatically fetch and push emails to your iPad each time new data arrives from the server. These are useful when your tab is your primary device for checking mail. But they do use up a lot of power. So if your tablet is only your secondary device for checking messages, turn off the Push and Fetch features and manually check for emails on your iPad to save more battery life. If you really need to use Fetch, then set it to the minimum frequency you need. Go to Settings > Mail, Contacts, Calendar > Fetch New Data, and make the necessary adjustments.
Handoff lets you share activities between your Apple devices. For example, you can receive phone calls on your iPad. Or you can finish an email or chat message you started on your Mac on your tab. However, being another form of wireless technology, Handoff will still suck iPad battery juice even when you’re not actively using it. If you use your tablet for totally different tasks from your iPhone or Mac, then disable Handoff. Go to Settings > General > Handoff, and disable the feature.
8. Don’t let your iPad battery heat up
Apple recommends keeping your device between 62 to 72 degrees to keep it comfortable. This is because too much heat can affect battery life. Avoid placing your tab on top of hot surfaces and keeping it in the car in the summer. And keep it in shaded areas when at the beach. You should also remove it from its case when charging.
9. Manage your apps
The debate of whether closing apps to save battery is making things worse or better is still ongoing. But it is common knowledge that apps do eat up iPad power. So at least try to manage how your apps use your precious battery juice.
Check what your top battery-hogging apps are. If not needed, then close these apps until you can recharge. Go to Settings > Battery > Battery Usage.
It is also best to turn off Background App Refresh. This feature lets apps refresh their content in the background. It may be useful for some apps you use (social media, news, etc.), but it also eats up a lot of battery. Go to Settings > General > Background App Refresh. Then disable it or select which apps you want to keep it enabled.
Turning off app notifications can also save power. When you get automatic notifications, your iPad display will turn on and light up each time you receive a new one. So disable this, or just choose which apps can still send you automatic notifications. Go to Settings > Notifications, and make the necessary changes.
Finally, avoid using the Automatic Downloads feature for apps. Automatically checking the app store and downloading updates eat up battery life. So it’s better to download updates manually. Go to Settings > iTunes & App Store > Automatic Downloads > Updates, and disable it.
10. Stay up-to-date
Make sure you have the latest iOS available for your device. Apple OS updates get rid of bugs and usually includes improvements for performance and iPad battery life. Check for updates by going to Settings > General > Software Update.
Apple advises maximizing battery life and battery lifespan to get the most out of your iOS devices. There are just a few tips to enjoy more battery life for your iPad. What other tips do you have?
If you have updated your device to Apple’s iOS 12, then there are certain things that you should keep note of. The performance of different iPhone models has been improved. Check out this speed test comparison for more details. However, if you want to save battery life on iOS 12, there are numerous ways of doing so. This will allow you to make the most of the available juice, utilizing the maximum usage time. Let’s dive in to see how you can save battery life on your iPhone, iPad and iPod touch running iOS 12.
Tips To Save Battery Life On iOS 12 For iPhone, iPad, And iPod Touch
iOS 12 brings a plethora of new upgrades. It introduced a lot of new features such as Siri Shortcuts and it also released extensions to some of the existing features like new notification management. While it’s too early to talk about the impacts of iOS 12 on your device’s battery life, here’s how you can save it.
Turn Off Background App Refresh
One of the oldest tricks in the book to save battery life is to Turn Off Background App Refresh option in settings. You can do this by going to Settings > General > Background App Refresh and turning it off. You can also turn off background app refresh for specific apps.
Limit Or Turn Off Location Services
Your apps use your device’s location for a lot of reasons, mainly for providing relevant content. However, it does take a lot of battery life. If you don’t need location-based services, you can always turn it off. you can do this by navigating to Settings > Privacy > Location Services and then turn them off.
Turn Off Wi-Fi And Bluetooth
It’s not compulsory to keep your WiFi and Bluetooth on at all times. You can turn them off to save battery life on your iPhone or iPad. You can turn them off from the Settings app as well as through the Control Center.
Turn Off Unnecessary Notifications
If you receive a bevy of updates every day, your battery life might take a hit. To avoid running into problems, you can always turn off or limit notifications from apps. You can do this from Settings > Notifications.
Turn Off Hey Siri
Enabling Hey Siri on your iPhone or iPad takes a massive hit at your battery life. This is due to the fact that your iOS device is consistently listening to the hot word. This feature, together with others will take away a portion of your battery. To turn it off you can head over to Settings > Siri & Search and then turn off the feature.
Turn Off Motion And Fitness
If you’re not into fitness tracking at all on your iPhone then it is best to turn off the feature entirely. You can do this by navigating to the Settings app > Privacy > Motion & Fitness and then turn off Fitness Tracking.
Use 2G or 3G over LTE
4G LTE takes in massive battery life compared to 2G or 3G networks. So it will be a good idea to shift to the latter. If you’re up for it, you can switch to 2G and 3G by going to Settings > Cellular Cellular Data Options > Voice & Data and then select either 2G or 3G.
Automatic Brightness Settings
Other than keeping your device to a pre-set brightness level, it would be wise to set it to automatic in order to save battery life. You can do this by going to Settings > General > Accessibility > Display Accommodations and turn ON the Auto-Brightness option.
Reduce Motion Over System Animations
Reduce Motion basically allows your device to stop system animations and provide a fluid jump to the next screen. Since animations require the aid of GPU, it makes use of more battery. To turn System Animations off, you can head over to Settings > General > Accessibility > Reduce Motion and then turn it ON.
If your battery life is draining faster than usual, then Hard Resetting your iPhone could potentially resolve the issue as it tends to fix any errors that might have prevailed. You can do this by tapping the Power button and the Home button simultaneously on iPhone models with a Home button. On the iPhone X, you can force restart the device by quickly pressing and releasing the Volume Up button, then quickly press and release the volume down button and then finally press and hold the side button until the Apple logo appears.
Clean Install iOS 12
If everything fails, try installing a clean version of iOS 12. Be sure to make a backup of everything.
These are some of the tips to save battery life on your iPhone. Be sure to try them for enhanced battery life. There will be more to the story, so be sure to stay tuned in for more details.
As you move from one part of town to the next, your iPhone intelligently moves from one cellular connection to another in an effort to maintain the highest-quality internet connection that it can. Unfortunately, sometimes the iPhone favors slower connections with a higher signal over faster connections with a lower signal, and this can impact performance.
Those who’d like to have more control over their handset’s cellular network selection might take a liking to a newly-released jailbreak tweak dubbed NetworkManager by iOS developer NoisyFlake, as it lets you switch between preferred network type(s) on the fly.
As you can discern for yourself in the screenshot examples above, NetworkManager adds a new toggle button to Control Center that can be used to switch between 2G, 3G, and 4G LTE cellular connections on demand. As you tap on the button, it cycles through the different cellular data types; the one it stays on becomes the highest-priority data connection.
Upon installing NetworkManager, you’ll find a dedicated preference pane in the Settings app where you can configure it to your liking:
- Toggle 2G selection on or off
- Toggle 3G selection on or off
- Toggle 4G LTE selection on or off
As you might come to expect, keeping all the selections turned on means that they’ll appear in the toggle button cycle. If you disable one, then it won’t appear as you cycle through the options in Control Center; this is handy because you can fully-disable falling back to a sluggish 2G network if you wanted to.
It’s also worth noting that NetworkManager has a few caveats. According to the developer, the tweak won’t work on your handset if:
- You’re using an eSIM
- You can’t make or receive phone calls when locked to 4G LTE if your carrier doesn’t support Voice-over-LTE (VoLTE)
- You must set the toggle back to automatic before uninstalling the tweak, otherwise your phone will remember your selection after the uninstall
Depending on the circumstances in your neck of the woods, NetworkManager may help you improve device performance or save more battery. The tweak is available for $1.49 from the Packix repository in Cydia or Sileo and currently supports all jailbroken iOS 11 through 14 iPhones that meet the criteria above.
What are your thoughts regarding NetworkManager and its potential uses in real life? Let us know in the comments section below.
Apple doesn’t market the new iPad as a $630 Wi-Fi 4G/LTE router, but tests have found the tablet can be used for up to 24 hours as a personal hotspot. Under the right conditions, you can use the new iPad as a wireless router for an entire day on a single charge, independent testing from AnandTech and The Verge indicates.
Those with a new 4G iPad with AT&T service need not apply: the personal hotspot feature is only enabled on the Verizon version of the tablet, while internationally the feature is available for 3G connections on certain carriers and it could be charged extra. The feature allows you to share the 4G LTE connection from your iPad via Wi-Fi with up to five devices.
Under normal circumstances, Apple’s own battery estimates indicate that you would get some 9 hours of Web browsing over 4G on the new iPad, claims that have been mirrored by most real-life tests. But if you switch the display off, along with disabling notifications and push e-mail, you could use the new iPad for much longer as a 4G LTE router for your laptop.
In its tests, AnandTech was able to use the new iPad as a personal hotspot with the screen turned off for a little more than 25 hours, while a test from The Verge obtained just over 24 hours — a notable feat for Apple’s new tablet, and much longer than it would take you to use up your entire monthly data cap.
The achievement is of course thanks to the much bigger battery inside the new iPad, 70 percent larger than in the iPad 2. The 42.5-watt-hour battery is needed to power the high-resolution Retina display on the new tablet, which draws out most of the power — as the personal hotspot tests show as well.
The new iPad battery has been subject to close scrutiny over the past few days. Meanwhile, PCWorld’s tests have found that the new iPad does not run hotter than competing tablets.
