The Ultimate Guide to Solving iPhone Battery Drain


I labored on the Genius Bar for nearly two years, and probably the most troublesome situation to unravel was brief iPhone battery life. It was extraordinarily troublesome to pinpoint the precise cause why somebody had iPhone battery drain.

I made it my mission to find the precise causes for iOS battery drainage. This text is a product of my years of analysis and anecdotal proof I gathered within the tons of of Genius Bar appointments I took throughout my time as a Genius and iOS technician, in addition to testing on my private units and the units of my pals.

This isn’t a type of “Flip off each helpful function of iOS 10” posts that grinds my gears. My objective is to ship sensible steps to really remedy your iOS battery woes.

One fast factor earlier than we begin — 99.9% of the time it isn’t truly iOS that’s inflicting your battery to empty shortly. I assure you that should you erased your telephone and there have been no apps or e-mail on it, it might final for ages. However, nobody makes use of their system like that, nor ought to they. Hopefully with these steps you may be dwelling with nice iPhone battery life whereas nonetheless utilizing all of the apps and options you’re keen on.

However first, we have to check and see in case you also have a drawback to start with.


Methods to Check For iPhone battery drain

There’s a fast and straightforward battery life check constructed into your gadget, if you perform a little little bit of math — the Utilization and Standby occasions. Head on over to Settings > Basic > Usageand take a look at your occasions.

In iOS 9 and up you’ll find the occasions in Settings > Battery (it’s a must to look forward to the listing to load), then scroll all the best way to the underside.

Your Utilization time is how lengthy you’ve truly used your gadget, and the Standby time is how lengthy your gadget has been dormant in-between the occasions you’ve used it plusyour Utilization time. A greater identify for Standby time can be “Complete Time since unplugged.” The important thing to search for is that your Utilization time ought to be significantlylower than your Standby time, until you’ve been utilizing your gadget each single second you’ve had it unplugged. If this isn’t the case and your Utilization time is strictly equal to your Standby time, you will have a extreme drawback. The underside line is that your Utilization time ought to be correct to how a lot you’ve used it because you took it off the charger.

So right here’s the check: write down your utilization and standby time, press the sleep/wake button (or lock button, as some name it) to place the system to sleep, and set the gadget down for 5 minutes. Whenever you come again, pay attention to the change in time. In case your gadget is sleeping correctly, then the Standby time ought to have elevated by 5 minutes and your Utilization time by <1 minute Three. In case your Utilization time rises by multiple minute, you might have a drain drawback. One thing is maintaining your system from sleeping correctly, considerably shortening the time it can final.

Should you don’t have a battery life concern, then nice! You don’t even want the steps listed on this article. However should you or somebody you already know is consistently complaining about how brief their battery lasts, learn onward or ship this publish to them.

Listed here are the primary causes of iPhonr battery life issues I’ve discovered, and how one can resolve them.


Step 1: Disable Location and Background App Refresh for Fb

This primary step to fixing iPhone battery drain could seem extraordinarily particular, however that’s as a result of this can be very widespread and very efficient. It has additionally been nicely examined and confirmed on many units.

I simply obtained the iPhone 5s about two weeks in the past, and thought my battery was draining just a little too shortly. Being the nerd that I’m, I made a decision to run the app Devices from Xcode, Apple’s developer software, as a way to see what the issue was. Principally, Devices acts as an Exercise Monitor on your iPhone, permitting builders (or nerds like me) to see each course of presently operating and the way a lot reminiscence and processing energy every app is utilizing in real-time.

Throughout this testing, Fb stored leaping up on the method record although I wasn’t utilizing it. So I attempted disabling Location Providers (four) and Background App Refresh (5) for Fb, and also you’ll by no means guess what occurred: my battery proportion elevated. It jumped from 12% to 17%. Loopy. I’ve by no means seen that occur earlier than on an iPhone. The iPod contact reveals this conduct, to my reminiscence, though I haven’t examined it shortly. For the iPhone, the battery proportion is often fairly constant. (6)

I’ve confirmed this conduct on a number of iPhones with the identical outcome: proportion factors truly improve after disabling these background features of Fb.

Dangerous, Fb, dangerous.

Step 2: Disable Background App Refresh for Apps You Don’t Care About

My current publish provides an in-depth rationalization of Background App Refreshif you need to know extra. Background App Refresh is an superior function added in iOS 7, however you don’t essentially want it operating for each app that helps it. Disable Background App Refresh for Fb or different apps you don’t completely want to remain up-to-date on a regular basis.

If there are apps you verify often, and also you belief the standard of the app and developer, then allow Background App Refresh with confidence and luxuriate in your apps being up to date intelligently in order that they’re prepared on your enjoyment at a second’s discover. Background App Refresh is nice should you want it, however you actually don’t want it for each single app in your iOS gadget.


Step Three: Cease Quitting Your Apps in Multitasking

iOS 7 made it tremendous enjoyable to shut your apps: all it’s a must to do is double-click the house button and swipe up on the app preview to blast it right into a digital black gap.

What most individuals inform you is that closing your apps will save your battery life as a result of it retains the apps from operating within the background.


Sure, it does shut down the app, however what you don’t know is that you’re truly making your battery life worseif you do that regularly. Let me inform you why.

By closing the app, you’re taking the app out of the telephone’s RAM (7). When you assume this can be what you need to do, it’s not. Whenever you open that very same app once more the subsequent time you want it, your system has to load it again into reminiscence yet again. All of that loading and unloading places extra stress in your gadget than simply leaving it alone. Plus, iOS closes apps routinely because it wants extra reminiscence, so that you’re doing one thing your system is already doing for you. You are supposed to be the consumer of your gadget, not the janitor.

The reality is, these apps in your multitasking menu are usually not operating within the background in any respect: iOS freezes them the place you final left the app in order that it’s able to go should you return. Until you’ve enabled Background App Refresh, your apps are usually not allowed to run within the background until they’re enjoying music, utilizing location providers, recording audio, or the sneakiest of all of them: checking for incoming VOIP calls (eight), like Skype. All of those exceptions, in addition to the latter, will put an icon subsequent to your battery icon to provide you with a warning it’s operating within the background. (9)

If you wish to know extra about this, right here’s an extended rationalization on why closing your apps hurts your battery life.

Step four: Disable Push E-mail Briefly

If steps 1 by way of Three didn’t clear up your drawback, attempt disabling Push e-mail briefly to see if it helps (10). Push e mail permits your gadget to obtain prompt notifications each time you get an e mail. It’s nice if it is advisable to know when each single e mail is available in, however does influence battery if configured incorrectly.

I’ve seen many units the place Push is the first explanation for battery drain, however I’ve additionally seen loads of units have nice battery life with Push enabled. It’s actually particular to your e mail and server settings. Attempt altering the setting to Fetch each hour, thirty minutes, or fifteen minutes and see if the drain stops. If that doesn’t assist, flip it again on. You possibly can additionally making an attempt disabling Push on particular person accounts if in case you have a number of. Simply maintain referring to the check originally of the article to see if that resolved your challenge.

[AdSense-A]Unbelievably typically, particularly with Trade push e-mail, it’s as if the telephone will get caught in a loop checking for e-mail always. When this occurs, the telephone will often die inside six hours of being off the charger, and the Standby and Utilization occasions in Settings > Common > Utilization will probably be precisely the identical. These occasions are usually not the identical as a result of the “firmware (11) is dangerous or corrupted”, it’s as a result of push e mail is holding the telephone from sleeping correctly.

In my expertise, malfunctioning e mail push is the first purpose for iPhone battery drain, and iOS 10 truly may need made it worse. There have been stories that after upgrading to iOS 10 that e-mail push was re-enabled for all e mail accounts. Go and switch it off now! Settings > Mail > Accounts > Fetch New Knowledge and switch it off on your accounts. Often iCloud accounts are protected for push however Trade, Hotmail, and some other type of e mail can’t be trusted to deal with Push adequately.


Step 5: Disable Push Notifications for Apps That Annoy You

Does that annoying recreation your youngster downloaded hold sending you push notifications to maintain shopping for extra digital sheep for the digital farm? In that case, each time you get a type of notifications, your telephone wakes from sleep for a number of seconds to mild up your display and wait on your potential motion upon every notification.

Push notifications don’t trigger extra battery drain by default, so please don’t hear me say you want to flip all of them off. Nevertheless, each message wakes your system for five to 10 seconds, so it may add up. In case you obtain 50 notifications through the day and by no means act on them, that may add four to eight minutes to your Utilization time, which means you now have that a lot much less time to do belongings you truly need to do in your gadget. (12)

Flip off these annoying Push notifications for apps you don’t want notifications from. It is perhaps a small distinction, however it may add up.

Step 6: Flip Off Battery Proportion

That’s proper, you heard me.

Flip off that battery proportion meter and cease worrying about your battery drain. You will discover this setting in Settings > Common > Utilization, proper above the place your battery occasions are listed.

One factor I discovered in my Genius Bar expertise is that folks which might be anxious about their iOS gadget battery life are continually checking it to see the share and the way a lot it has dropped from the final time they checked it. So should you examine your system twice as a lot, merely to verify on the battery life, you’re primarily halving the time your system will final.

Cease freaking out and luxuriate in your life. There are extra essential issues to fret about than your gadget’s battery life. The management freak inside you may freak out the primary few days you do that, however you’ll get used to it. (13)

Step 7: Go to an Apple Retail Retailer

Replace: I used to be knowledgeable after posting this that the Apple battery check solely runs on the iPhone 5 and up.

I do know, you hate making a Genius Bar appointment as a result of it’s loud and loopy in there, however I’ve a great purpose so as to add this to the listing.

In line with my sources, Apple has rolled out a brand new ‘Prolonged Battery Life Check’ for all iOS technicians that permits them to see an in depth report of battery utilization in your system. It takes just a few minutes to run and, from what I’ve heard, is complete. I’ve not had an opportunity to see this check for myself, however my buddies inform me it rocks.

The opposite uncommon risk is that your bodily battery is flawed, and the technicians can exchange it totally free in case your iOS system is beneath guarantee, or very cheaply if it’s not.

Step eight: Allow Airplane Mode in Areas of Poor Mobile Service

One main cause you have iPhone battery drain is poor mobile service. When the iPhone detects that you’re in a spot of low sign, it can improve the facility to the antenna to be able to keep related sufficient to obtain calls (primarily) and keep a knowledge connection.

It will destroy your battery life in case you are continuously in a location with 1 bar or no service in any respect. The unlucky factor is that this will occur in additional locations than you anticipate — any constructing with metallic studs within the partitions, aluminum buildings, buildings with dense concrete partitions, closely populated metropolis areas, and downtown areas with with a lot of tall buildings.

Typically occasions you could get a robust sign on the highest flooring of a constructing, however merely shifting to a decrease flooring, such because the basement, will instantly trigger your iPhone to hold on to sign for pricey life on the expense of your battery. Notice that this extreme drain will occur even if in case you have a robust Wi-Fi connection, as a result of your telephone nonetheless wants the mobile connection for calls and SMS messages (the green-colored texts within the Messages app).

In case you are in an space with poor cell protection, and you continue to have to obtain calls, I’ve received dangerous information — there’s actually nothing you are able to do. But when your service is so poor you can’t obtain calls anyway, I like to recommend turning on Airplane mode by swiping up from the underside of your gadget to entry Management Middle and tapping the Airplane icon.

One factor chances are you’ll not find out about Airplane mode: you’ll be able to truly flip Wi-fi again onafter enabling Airplane mode. Simply faucet the Wi-Fi button in Management Middle (the icon on to the correct of the Airplane). That is good for locations, like an airplane, the place you have got zero mobile protection however a robust Wi-Fi sign.

In case you have Wi-Fi and need to be actually fancy, you’ll be able to disable simply the mobile knowledge portion of your sign, e.g. EDGE, 3G, 4G, or LTE. Most individuals don’t know that your telephone is definitely receiving two alerts concurrently: one for calls and SMS, and one for knowledge.

The sign power meter on the iPhone solely exhibits the sign power for the non-data connection, which suggests theoretically your iPhone might present 2-Three bars (or dots on iOS7) on your 1x connection however in actuality you possibly can be getting 1 bar of LTE/4G/3G connection, inflicting the telephone to enter heavy search mode. To disable simply the Knowledge connection of your iPhone, head over to Settings > Mobile Dataand change Mobile Knowledge off. Once more, doing it will help you obtain telephone calls (when you nonetheless have a sign) whereas sustaining a knowledge connection by means of Wi-Fi.


[NEW] Step 9: Allow Low Energy Mode

Low energy mode is the nuclear change for making your iPhone final a very very long time. In line with Apple’s documentation on Low Energy Mode, it turns off the next whenever you allow it:

  • E mail fetch
  • Hey Siri
  • Background app refresh
  • Automated downloads
  • Wi-Fi associations
  • Some visible results

Your battery will flip yellow iphone6-ios9-battery-low-power-mode-iconand your telephone will final for a number of hours longer than in regular mode. Because of this nice analysis on Low Energy Mode battery drainby Matt Birchlerat BirchTree, it appears like your iPhone lasts between 33% – 44% longer than regular utilization. Because the iPhone is slated to work for six hours of utilization, Low Energy Mode provides between 2 – 2.5 additional hours of utilization for a grand complete of eight – eight.5 hours.  That’s an enormous improve for such a tiny change.

To activate Low Energy Mode head to Settings > Batteryand flip the change there. Oh, and as of iOS 9.Three.1, you’ll be able to allow Low Energy Mode and Night time Shift on the similar time. An alert will mechanically ask you if you wish to allow Low Energy Mode when your iPhone hits 20% battery

Low Energy Mode additionally gives the aspect advantage of fixing my gripe in footnote #13, which is that it’ll mechanically allow your battery proportion. My dream setup has been to have battery proportion disabled (Step 6 from this text) from 100% to 20% and battery proportion enabled from 20% – zero%, which is strictly what this provides me if I allow it when it provides at 20%. Thanks, Apple! Hopefully any person inside Apple learn my weblog. One can hope, proper?

Because of commenter, Stefan Mohler, for stating that my proportion gripe was solved!

Step 10: Buy an exterior battery pack or case

If all else fails, tt could also be that you’re merely an influence consumer and also you exceed the battery limitations of the iPhone you personal. In that state of affairs, your only option is to buy an exterior battery pack or a battery case.

Advisable Battery Pack

The Anker PowerCore 20100 is the perfect exterior battery pack I’ve discovered to date. It isn’t too heavy (12.5 ounces), slides simply into totally different sorts of pockets in your bag, and may recharge an iPhone as much as 7 occasions from zero to 100% relying on the mannequin. You may as well cost two units directly. ?

Advisable Battery Case

In case your gadget continues to be not lasting you a full day, and you may’t abdomen heading into one of many chrome steel noise chambers I lovingly discuss with as your nearest Apple Retail Retailer, don’t fear. There’s nonetheless hope for you.

The rationale your gadget isn’t lasting all day may merely be as a result of you’re a heavy consumer, and your iOS gadget is appearing utterly regular underneath the grueling tempo with which you employ it. That isn’t a fault of the gadget, otherwise you, for that matter. You’re merely pushing it past it’s capabilities. My recommendation for you is to purchase a automotive charger, a second charger for journey/work, or a battery case to increase your battery life (14).

I hope this text empowers you to cease stressing about your battery life, and frees you as much as benefit from the nice system in your palms. There are extra essential issues in life that deserve our consideration, so the extra we reduce the trivial stressors, like dangerous battery life, the extra time we will spend on individuals and issues that basically matter.

  6. Word about battery proportion: it’s an estimateof how lengthy your gadget will final wanting on the quantity of cost left within the bodily battery and evaluating that to the present processes draining that financial institution of electrical cost.A superb factor to match the best way iOS calculates battery proportion is ETA (estimated time of arrival) in trendy GPS and navigation. Most units take a look at the miles left to journey and examine that to the velocity limits of all the roads you will journey in your present route. For those who drive quicker than the velocity restrict, you’ll get there quicker than the estimated time, so it’s not 100% correct.Battery proportion estimates work the identical approach, wanting on the quantity of juice left (miles) versus how briskly you’re draining it (miles per hour).

  13. I actually want Apple had a “No battery proportion meter besides underneath 20%” setting, so dangerous. That may be my superb configuration.Yay, Apple semi-solved this with Low Energy Mode, which I clarify in Step 9.
  14. Or purchase a second iPhone as your night time telephone ?
