ios 10.2.1 to 10.3 battery drain

I have iPhone 6 and just put 2 & 2 together after turning phone off to sleep and when woke up and. Powered up phone it was at half the battery percentage from this morning. (70%>>>35%)

I was noticing lately in dimly lit rooms that even when phone is locked the home screen is still visible (barely noticeable) I confirmed my suspicions by looking at Battery Usage in last 24 hours! Home and Lock Screen is using 39% of my battery!!! I would bet my life on it that this is an IOS update issue...

You would lose your life. If it was an iOS update issue why doesn't it happen on every phone that was updated (about 200 million), or even a measurable percentage of those phones? Have you read this thread? How many others have reported that it was Home and Lock Screen?

Lawrence do the numbers having a bad experience with this update seem higher than normal to you?

Do you know how many have had a problem as you're probably closely allied to Apple, from how you comment on this thread?

Do you know what % of those who originally say it seems to be better when they follow your suggestions have continued to have success?

Everybody on this thread is (or used to be) an Apple Fan Boy. Everybody here love (or used to love) Apple products. But Lawrence is in another level. He will defend Apple even if his iPhone explode like the Samsung Note 7.

Please, Lawrence. A lot of people here is complaining about the same: battery drain after updating to iOS 10.3.
A lot of people complained about this since the beta version. I'd post here the links about that, but the forum erase them because here you can't write about those versions (weird), but you can do a full search on google.

If there is no more people complaining about this here is because no many people knows about this Apple discussions forum. And there is a lot of people (snapchat users, instagram users, etc) who are used to charge their phones twice or more times a day, because they drain all their battery with this kind of apps and games.

But people like us who are used to use their iPhone in a professional way, we know that after updating to iOS 10.3, the battery drains faster, a lot faster.

If everybody here reads the whole thread, you will see that no many have found any other solution for this than replacing their phones with a new one. iOS 10.3 is causing a very weird failure. You can reset your phone and not install or restore any app for a whole week, and you'll see that the problem is still happening. It's not an external app problem. It's not the Facebook app, it's something on iOS 10.3

Lawrence, if you have a good tip for the community to resolve this, please, share it with us. If you will only write to say that we are crazy and we are losing our time, and that if is not happening to you it's not happening to anyone else, please, leave this thread.

I'm trying to say this in a polite way, but english is not my language.

Thanks. I know you picked off the numbers of pages of post in these forums as a guide, but I don't suppose you know what Apple's estimates are?

Do you know what % of those who report that its better after they follow your suggestions have since maintained that?

As you can see top right corner, battery is 97% after being on for 3+ hours (not being used)

That's great news!! The bad news is--SOMETHING WAS CHANGED within the settings via Software Update!! Remember not too long ago when WIFI-ASSIST became the default "setting" and millions of iPhone users started burning up data?? Tech savvy users would be the only ones to notice it and post on forums to rectify it. So I agree with you. The update itself isn't to blame for battery drain, it's the new default settings that came along with it. (Ex. Widgets, app background refresh, home button, lock screen etc). Gratefully I returned all those settings to prior update functionality and did hard reset. I'm confident that my issue is resolved but I feel bad for the common folk who will probably be sold a new battery at the Apple Store in a Hail Mary attempt to fix their draining battery issue$$$

As far as the guy who spewed out statistics of this current issue only taking up 9 pages of forum space compared to the 100's due to past IOS versions. Wait a couple of months and spew us the NEW total! This update is fairly new and I hardly think the majority of iPhone users even notice the color of their phones let alone the battery consumption difference...

As I stated in reply to the spewing of only (9) pages worth of forums pertaining to the battery drain issue, it now has jumped to (19) as shown in attachment. I'm a newbie to this posting on forums but must agree with guy who suggested to post recommendations to help rather than play the shame/blame game and make the rest of us feel like we are imagining things...

I took the advice of helpful users and shiut off a bunch of settings that MIRACULOUSLY appeared after the latest update!! Thank you all, you know who you are

How many others have reported that it was Home and Lock Screen?

For the record, "Home and Lock Screen" was listed as one of the bigger battery drainers for me. It's just that apps like Facebook, YouTube and Whatsapp (which I used fairly frequently) ranked higher, and that's what I focused on instead of the home screen. Other users might have faced the same situation and thus only highlighted other apps. Or they might not. It's just not a good enough "evidence" to conclude that it could never be the result of an iOS bug.

If it was an iOS update issue why doesn't it happen on every phone that was updated (about 200 million), or even a measurable percentage of those phones?

Even the most prominent "actual" iOS bug affected only 5% of all users. That's a pretty small percentage (although because so many people use the iPhone, the absolute number can be large). What if there's an iOS bug that affects 1% of all iPhones? Or 0.1%? Or 0.01%? It's not entirely impossible, especially since you're talking about an operating system with millions of lines of code. Even an app could have one line of code that affects 0.1% of users—what more an OS with millions of lines of code?

I think you should drop the fallacy that as long as an insignificant percentage of users report the bug, it could never be an iOS bug. Like others have mentioned, the beta testers reported battery problems. Also, according to the history of forum posts, it seems that every update introduces battery problems to a small subset of users. Does it mean that all those problems are actually not caused by an iOS bug? No. There really isn't any logic to that conclusion. Software companies often focus on the biggest bugs, and it is possible that Apple chose to let these small bugs slide and focus on bigger problems with the newest iOS.

Here's what I do know about my case. I had immense battery drainage after updating it to iOS 10.3. I tried many solutions, including installing my phone as a new phone, trying to re-calibrate the battery, deleting battery killing apps, etc. Apple Support couldn't think of any more solutions I could try. The Apple Authorised Service Provider couldn't think of any solutions that could solve my problem. Diagnostics show 100% perfect hardware. In the end, they decided a replacement unit was the best solution. I took the new unit, restored my backup (i.e., installed all the "battery killing" apps like Facebook and YouTube)—and boom, problem solved. No more battery draining issue. Could it be an iOS problem? I think it's highly likely. I can't prove it, but I think it's more likely to be an iOS issue than a usage, app, or hardware issue.

It's just really, really counter-productive (and even borderline nasty) to constantly delegitimise other users' battery problems with faulty iPhones.

Again, to iPhone users facing this problem: approach Apple Support to solve your problem. Be insistent on solving your problem—don't blindly accept that you have to turn your smartphone into a call-and-SMS-only dumb phone in order to get back to previous levels of battery life. It's likely that Apple Support will either solve your problem, or replace your phone for free (yes, even for phones that are no longer covered by the warranty).

Interesting observations.

I'm just wondering whether 10.2 and 10.3, apart from knobbling battery life via either changing default settings or not playing nicely with some existing apps, has also uncovered a hardware incompatibility in some phones where all the recommended fixes and Apple experts fail to resolve this??

It is possible and almost certainly true that all the components across all models or even within the same model, will not have exactly the same components and so behave in different ways when the iOS code hits it.

That would explain this increasing, and in some cases, unresolvable problem.

So not entirely an iOS error but one where it has revealed the weakness of hardware variability or QA.

If that is the case, this would explain why Apple are exchanging phones for new ones.

If your phone is under warranty, it is worth backing everything to the cloud or iTunes/computer, applying the new iOS and be prepared for the battery problem, trouble shooting or take straight to Apple Support and if they cannot fix it, insist on a new one.

There may be a justification for phones outside the warranty as they have just created the problem!

Hi! I'm an iPhone 6 (2014) user and I'm pretty sick of this issue. Atleast twice or thrice my phone switches off randomly. It's so unpredictable. It can go from 80 to 20% charge in an instant! Hope Apple recognises this issue and solves it as soon as possible.

The same for me.

iPhone 6, update from 10.1 to 10.3.

The battery drops to 90% in just Ten minutes at The morning, sono after unplagging The Chargers.

NO apps in background.

1 hour in YouTube drops the battery to just 32%.... at 10:15 am!!!!!!

ENOURMOUS battery drain issue....

Facebook has always been a battery hog. The last version (which came out the same time as the iOS update) was especially bad; I believe that FB has released another update that helped, so see if you have one available.

Safari is almost always caused by having a lot of open pages with one or more that automatically updates. Close all of your Safari pages and the problem should go away. To do that open Safari, tap on the overlapped squares at the bottom right, and then tap the "x" on each page's upper left corner.

Thanks but It also drains while on standby while flying. Everything is closed! I could let it sit and not use it for 4-5 hours and lose 30%. All I do is use a few text messages and the battery has wasted away flying from San Diego to Indiana. (6.5 hrs.)

Yes, that's perfectly logical. When the phone's Airplane Mode is on all that does it turn off radios. It doesn't stop any background apps from trying to communicate and failing, using energy.

I'm puzzled by you saying you send a few text messages. How do you do that in airplane mode?
