iOS 10.3.2 update drains battery

I had the same issue when i upgraded to 10.3.1. My battery life went from over 24hrs to less than 6-8 hrs. But since upgrading to 10.3.2 it is now back to its previous best. I have a 6S with 128GB of storage.

just updated the OS. All my data and setting are retained. Just like updating to 10.3.2 but backwards.. No issues.. see the youtube video that the other guy posted earlier in this thread.. How To Downgrade iOS 10.3.2 To 10.3.1 With iTunes - iPhone - iPad - iPod Touch - YouTube

I am also experiencing significantly reduced battery life after updating my iphone 7 Plus to iOs 10.3.2. The most alarming symptom is idle battery drain. My phone will go from approximately 50% at night to 15% in the morning when I am asleep and not using the phone. I hope Apple releases a hotfix soon.

I believe that I may have found the answer to the battery drain issues with iOS 10.3.2 and why Apple has not answered any of us. There's really not an issue.

I was very upset and reverted back to iOS 10.3.1 my battery issues disappeared. But it still bothered me receiving requests to update from my iPhone 7 plus on AT&T continuously to upgrade to 10.3.2.

So I did the following. Backed up my phone with iTunes and archived it. Just in case. Charged my phone to 100%. Then did the update. I'm now running iOS 10.3.2 with no battery drain issues at all for serveral days.

With an iPhone 7 I''ve had a noticeable drain from 10.3.1 to 10.3.2. Full 100% charge in the morning and by noon I was down to under 50% without using the phone at all aside from an occasional text. . Far below normal for my usage.

I have exactly the same problem. Hot battery Runs out by 5 pm All personal music app disappears iTunes disappears

Suddenly the phone has become a nightmare of extras

I've dumped as many apps as I can and switched everything off

Is there some kind of leak where even if notifications are switched off submenu notification choices in each app are still running?

Now too complicated to troubleshoot without a visit to an Apple Store

However I just use the phone as a top quality B Roll video camera

Everything else except internet and mail are not much use?

Hello my friend - I miss my battery lasting all day long.. I had to start using my Mophie again...

Otherwise, no battery lasting even a full day with iOS 10.3.2

Please APPLE, do something tomorrow at WWDC conference.

I am having the same problem, and no apps appear to be a huge drain. I had no problem at all using the phone all day before the upgrade.

Is this something we should report to Apple- can you go back to the previous iOS?

Same scenario here ... After updating to ios 10.3.2 battery drain has started to happen on my iphone 6 and the phone remains warm at all time .. It is uncomfortable to the touch .... DO SOMETHING APPLE

Yes this is the issue of the ios 10.3, you can downgrade your iPhone by using the backup that you create in the iOS 9 version. Anyway, isn't that iPhone 7 plus installed ios 10 inside then why your iPhone 7 plus need to update to iOS 10?

No, you can't. Apple stopped signing any version of iOS 9 for phones that are capable of running iOS 10.

My iPhone 7 never had battery issues until this update. Not only that, my wife's iPhone 6 is having the same issue now. Both phones had no problems until this update. It's time to accept the fact that Apple is being very careless with the updates. You don't have to be a "grassy knoll" kook to believe this. Putting customers down on these forums for their comments is immature! I bet we have more to do during our days than gripe about Apple products! Just fix it!

Yes. I took my (previously very reliable) iPhone 5s to the Apple Store yesterday about this issue. They ran diagnostics and confirmed that the battery itself is fine and that the problem is the software, without actually acknowledging that it was caused by the software update. They claimed that a reset to factory settings would fix the problem (it didn't) but said there was another problem with the auto-rotate function that wouldn't be fixed by the re-set (also not true - that function is now fine) but since it's out of warranty, they very generously offered me a $70 trade-in on a new phone. Cheers Apple, thanks for nothing! I'm now carrying a portable re-charger around with me wherever I go.

I tried nearly every trick in the book but the only thing which seems to help is putting the phone in the Energy Saving mode (Settings->Battery->Energy Saving). Then the battery life is as expected. Be aware it is switched off when charging reaches 80% so you need to switch it on again when this level is reached...

Hoping to add to the clamor and get this fixed. Battery drainage on iPhone 6 terrible since 10.3.1. I was hoping that Apple would address this problem with 10.3.2 and instead saw even worse performance. With limited usage, I have to charge every 1 to 6 hours (which is hardly feasible during a 24 hour hospital workday). Moreover, I have a daughter with severe food allergies and hate to be without a working phone. I can no longer trust the phone to hold a charge for the limited time it takes me to go and pick her up from school unless the phone is fully charged (100%) when I have left home. The battery often drops from 100% to 67% to 40% and then frequently goes black mid-task. When it does come back on, it shows 1-7% charge available. But then when it is plugged in, it goes back to 40% immediately. Please fix this problem! If I have to buy a new smartphone over this, for the first time since 2008, it will not be an Apple.
