ios 10.2.1 to 10.3 battery drain

So I went through and changed everything to match my wife's phone as mentioned above. No changes. Battery is still being sucked away.

After reading the above post about the FIVE exchanges I have to think this all comes from the reformatting of our hard drives in 10.3 that gave us all more space but looks to have caused a battery drain when the phone is passive. This new file system is destroying Apple's credibility.

Interesting.

Did you try to factory reset your phone as if its a new phone. Some have had success that way.

Some resolved it by stopping iCloud on phone and also the PCs Sync'd with it.

Have you taken your phone to an Apple support genius?

The issue seems to also affect 10.2 so not sure about file system idea.

I still think it's to do with a different manufacturer or batch of a certain chip which is causing this.

Sounds like you have checked all settings, and ran good comparisons. I'm sure you've also had battery tests.. as you say you have an new battery.

Have you taken your phone in to Genius Bar for analysis? If not.. I suggest you do. Like Lawrence mentioned, sounds like you have a hardware issue.

When they run their tests (genius Bar) they'll be able to see what your phone charge is doing plugged in, vs unplugged presented with a graph. (I was actually amazed what the phone tracks as it's used). They can test components within your phone that an online tech cannot. It costs nothing, then at least you'll know exactly what's causing your issue. After all the work you've put in to testing your phone, I'd think that was your next step.

I have the same problem. Used to have iPhone 6 for 2 years. Battery started going (or so I thought), so I ordered the new iPhone 7. Have had it for a week now. Having to charge it twice a day. Brand new phone set up (not restored from old). No apps downloaded or anything.

My iPad, my wife's iPad and her iPhone 6S are also draining quickly.

It is 100% sure the software and definitely the update from Apple as it started happening after 10.2 I believe.

What is Apple doing about this? There is no point contacting them because I am not going to do reset etc on all devices.

I am also experiencing the same thing & have even gone as far as getting a newer 5s thinking mine had an issue. WRONG!! Same stuff happening to the new one since the latest update. It's frustrating because when one moment it is 100% charged then I take it out of my pocket to find it drained & dead. It takes almost 3 hours of being hooked back up to it's charger to acknowledge any battery. I've checked my battery usage & done all the suggestions to no avail of preventing this issue. We can't all have the same problem across different phone models & all be wrong.

I would actually suggest that all the people who has commented in this post because of this problem, write a report in that link, even those who already got their iPhone replaced. That's the best way to let Apple know that there is a real problem with iOS 10.3.

Yeah, I've been posting a lot here on this thread but I totally understand how it's impossible to know who is who. I've done it all. Resets, reset from DFU mode, reset from a PC, turned off cloud syncing, turned off every setting in the book, and replaced the battery. It has to be the software. How could over 2k people have this same issue? :(

I wish I could take it to a Genius Bar but I live in Jakarta and we don't have any of those here.

So, I am starting to get really annoyed with my iPhones now. Just want to chime in with my observations so far.

Two out of three iPhones in our household are going through the battery like there's no tomorrow (literally).

And this is with the phones doing absolutely nothing. Usage time and standby time are the same, which tells me that something is keeping the phones out of stand-by

iPhone 1: 5S 16GB - running 10.3.1 - Network provider A

iPhone 2: iPhone 6S 64GB - running 10.2.1 - Network provider B

iPhone 3: iPhone 7 Plus 256GB - running 10.3.2 - Network provider B (this phone is less than a week old!)

Last week, out of nowhere, iPhone 1 and 3 start draining battery. Both will be drained in less than 12 hours. There are no apps (that I can close) running. Both report same number of hours and minutes for usage and standby. iPhone 2 has no problems. At all.

Disabled push mail (fetch 1/hour), location services, background refresh of apps, feedback to Apple and developers. No effect. Tried soft-resetting both phones. No effect. The only way I can halt the drain is to put the phones in flight mode, but that is for obvious reasons not a fix. I am not sure that this is something that is specifically related to 10.3.2 as iPhone 1 running 10.3.1 also drains. I also can't attribute it to network provider misconfiguration or cell tower anomaly, as the behavior is present across different devices (one old, one brand new), software version, different network providers and different cell towers (behavior is consistent across work and home, separated by 30 km)

In an attempt to weed out faulty apps and wipe the slate clean, I restored iPhone 1 as new, with update to 10.3.2. I did not install anything else. No effect whatsoever. So it's not "household" chores like indexing messages and photos that is keeping it alive.

So, carried a big powerbank with me over the weekend. Then, Monday - EVERYTHING WAS BACK TO NORMAL on iPhone 1 and iPhone 3. Checked if any apps had been auto-updated or anything. Nothing. Nothing on my side was changed.

I hate when problems just vanish like that, because you never know when they'll resurface. But thankfully, I didn't have to wait anxiously for long. This morning, the phones started draining fast again...

I am starting to believe that this is something that is generated "server-side" (Apple), keeping the phone alive and chatting away or doing something for itself for some unknown reason. What it is, I don't know. But I have nothing running, so it must be kernel or system services. And the only way I can stop it is by putting the phone in flight mode.

This is a bug, a problem, a fault, an error. It is not something that can be countered by the usual boilerplate advice about how to conserve power. So Apple, please don't respond with the usual inane drivel about how to conserve power.

Respond to this as the very real problem that it is.

Why is there no reply from Apple?

Clearly there is nothing that we as customers can do. So communication from Apple would be great. At least admit there is a problem and that you are working on it.

Does Apple not communicate at all on Apple Forums? These forums are hosted on apple.com after all!

Apple hosts this user-to-user forum, but does not participate and does not generally read what is posted. To communicate with Apple use the Contact Support link at the top of every page. For general feedback https://Apple.com/feedback.

I understand that Apple generally don't reply, but surely there comes a time when there is so much negative feedback or problems, that Apple actually DO something about it ?! How does that get triggered?

Surely Apple can release a fix on a script to reconfigure what is wrong or provide a rollback to 10.1.1? Would they rather have all these negative comments flying around. Lawrence you've surely got a line to the Apple gnomes?

This is amazing work. Please don't forget to send them this post and a link to the forum in that feedback link posted earlier. I sent my information in, but it would surely help if others sent in their feedback. <3

Thanks, mate.

Did send this as feedback (well, a reduced version as the feedback form didn't accept the text amount.

I continued mucking about it with iPhone 1 last night, trying selectively to disable stuff. I had some amount of success by disabling BT (still mobile network and wifi enabled), which seemed to slow the draining.

Alas, my troubleshooting efforts were foiled as this morning, iPhones 1 and 3 show no battery drain symptoms. After 2.5 hours of a few text messages and idle, iPhone 1 is at 99% battery (network and wifi enabled) and iPhone 3 is at 100% (network, wifi and BT enabled)

I so wish that I had done screenshots of the Settings page with modem firmware version as I still believe there is something going on behind our backs. On the other hand, if Apple were to push a silent update, they probably wouldn't be so stupid that they left a trail in the form of a version number.

Whatever the case, the plot thickens.

There is no plot.

Apple can't push a silent update, as any update reboots the phone, so your touch ID won't work until after you enter your passcode manually.

Most likely whichever app or function was updating over the network finished.

"Most likely whichever app or function was updating over the network finished."

Did you not read that I wiped one device and installed as new - and still the problem persisted? So, after installing as new, to latest IOS, you suggest that it still needs to update apps for days?

You are trivializing the issue.

By the way - Apple created the HW and the SW and owns the full ecosystem - I am quite sure that they can push whatever they would like, when they like. They can on MacOS, so why wouldn't they be able to on IOS.
