Fix: iPhone 7 Battery Draining Fast

News:

I tried to erase all contents and settings. A message pop up: icloud is uploading files ( ???!!!!!). Do you want to continue and lose the documents or du you want to finish first uploading the documents?

I pressed uploading the documents button. A progress bar appeared and did the job up to 100%. Pressed again the erase all contents and settings and voilla: SAME STORY.

Repeated the above steps few times and SAME STORY all all the time.

So something on icloud does't work right. That's why the battery is drained so fast. Will keep you posted.

I've had problems with my battery for ages. I tried the solution to switch off and sign out of iCloud and that actually solved it for a day or two, so I then signed back into my iCloud and the battery when back to being bad again. So I signed out again hoping that would solve it again but it hasn't so now I have no idea what's going on. Tried resetting all settings. Apple have said the only way to solve this is to completely wipe my phone and start again but then I'd be losing everything which I'm not super keen on.

If anyone has any last-ditch attempts to help me, I'd be very grateful!

This is happening to my husband's phone. I hope one of these solutions works! I've read some of the comments saying it's the Facebook App that's the culprit but he doesn't have that or the app. Waiting for him to get home from work so we can fix the problem!

Uninstalling iCloud for Windows fixed the issue for me! Before uninstalling, the battery was draining by about 10% per hour; after uninstalling the battery is at 73% after a day of light use on my iPhone 7 Plus (iOS 10.2).

I have to say I was skeptical about iCloud for Windows being the cause of my battery drain. But after having Apple changing the battery in my iPhone 6s, trading it in for a new iPhone 7, working with Apple support for 3 days on the iPhone 7 and taking it back to Verizon and returning it for a second new phone, and countless hours uninstalling, resetting, and other troubleshoot steps trying to figure out why my phone keep draining the battery so rapidly I figured what the heck, let’s give it a try. Another thing I noticed after all this with my iPhone was my iPad Air and iPad Mini (both connected to my iCloud account) were also rapidly draining the battery. Saturday I uninstalled iCloud for Windows on my office computer and my home computer. Put all devices on charger for a full charge. Sunday I used my iPhone all day long in a normal manor, was off the charger from 5am to 10pm and still had 74% charge. Both iPads have remained fully charged. There is no doubt in my mind uninstalling iCloud for Windows fixed my problem. I’m amazed and very thankful to desiadri for posting this solution, it was driving me crazy trying to figure this out. I’d like to understand what about iCloud for Windows causing this, but for right now I’m just happy my phone will hold a charge throughout the day and I no longer have to throw it on a charger every change I get.

You're welcome man and I'm glad that I helped you as I understand first hand how frustrating this issue is, what's strange is that no one at Apple has come clean and accept the issue and move this to the correct department to be fixed but in the meantime let the people know about it so they can at least temporarily Uninstall iCloud for Windows and I'm sure people will prefer having a normal working phone to an application in your computer that you may barely or ever use.

I also thank you for being the first person to thank me for finding and fixing this, incredibly no one here or in other forums I've posted about it have done it, they acknowledge that it fixed the issue but not a thanks, without even mention Apple that even when I sent them a detailed email explaining the issue and the solution they didn't even reply to the email or even confirmed receiving it, nothing. So thanks and I'm really glad this has help you.

Oh, your and my problems are sooooo much the same desiadri! I'm on my 3rd replacement iphone and all 3 do the same thing. They work great for a week or two, then bam something happens and the drain changes from about 15 per hour (when it's working good) to 6-8% per hour without even using the phone. In fact, when the drain is excessive it drains 6-8% per hour, if I'm using the phone constantly or if it is sitting on my desk and not being used...

I too sometimes will have 6-8% drop per hour at work, but when I leave work the drain is back to 1% per hour. I am in a high reception cellular area, and have tried everything since October. I'm getting really frustrated after 3 months with this problem. I only have about 6 apps installed at this point because I keep restoring to new and starting over, but I'm beginning to think it's not the apps. Oddly it happened today when I left work and forgot my phone, so the phone was disconnected from my watch and it drained 25% in a hour and a half- could it have something to do with the iphone? If you figure any more out, please let me know...

Like I mentioned above, yes I feel confident that I finally found the culprit of all this mess, reading what rating here and other places this is a well known issue and because it doesn't affect everybody it hasn't given the proper resources to found the issue and fix it. I don't know you but I think I have saved Apple tons of money, sadly I won't receive even a thanks for it...;)

Anyway, please notify this to Apple, I did my part and sent a very detailed email to my Support advisor and I just hope he has forwarded it to the correct department so this can be given the attention it needs to find what causes the issue with iCloud for Windows and only in some phones and can be corrected on a future update.

Same here. Iphone 7 plus 256GB. My wife has iphone 7 256 and I don't even can obtain half of her usage time. Tried everything from reset al settings to dfu install. I'm on 11.0.2 and I wanted today to downgrade to 10.3.3 but guess what? Surprise! They are not signing anymore. Apple, are you really doing this kind of ***** 😟

If ANYONE from there is reading this have in mind that I am using Iphone since the first one. Don't wanna tell anything about the other devices.

later edit: I'm not using facebook at all. I'm not using windows so therefor I don't have icloud for windows. I have 5 programs installed and that's all about it

I found a permanent solution to the battery issue. Get a phone that doesnt have apple on it. This is my 3rd iPhone in less than 2 years, all 3 have had problems. I get no help from apple, oh you need to go to Apple Store, well im not driving 2 hours to go to an Apple Store. I work away from home and depend on my phone, i have had issues as to where i cannot make phone calls, text message, speaker phone not working, freezes constantly, full service lte and wont connect, and now the battery drain is on average of 10% in 15 minutes. Needless to say once i get home, i am taking my iphone to my garage, smashing it with my sledgehammer, and getting a phone that actually works. I had a $30 walmart phone that worked flawlessly, this $900 phone is totally useless. Bye apple in 8 days, i will turn everyone away from your products as well

I have got an Apple iPhone 5s and I have it for 5years without issues . Two

months ago I took it too a specialty phone shop in Limerick and got them to

install a new battery which was35 euros , I have a few issues since that

with the charging one time it’s 22 % charged and when plugged in it’s 50 to

60 % . I think this is a fantastic iPhone for constant use, could never

fault my iPhone . Cheers . Martin .

I m no expert, but sounds like you have very poor signal in your office, so the battery is draining because of the phone's effort to compansate somehow for the loss of it. Something is blocking your signal reception

DRKCOPE~ Is your directions a FIX or temporary solution?

I bought a new 7 Plus phone to replace the 6s Plus. Both phones are running 11.1.2 and the 6s Plus battery seems to last longer than 7 Plus. I know that other users have the same or similar issue as I do. I am not using the 7 Plus to watch movies or play games. I know about the factors that contribute to reducing the battery.

I don't know yet if the battery performance is due to hardware or an iOS issue. I do know that the 6s Plus has longer battery life than 7 Plus. The funny thing about this, I have a lot more Apps set to background refresh on the 6s plus than 7 Plus and the battery last longer on the 6s Plus. Also, on the 6s Plus, Facebook is about 24% usage and I still get good battery life on the 6s Plus.

I know others have complained or have a similar issue regarding the battery ion the 7 Plus.

Dude thank you so much that worked great. Was going to go to Vodafone but you fixed it thanks

Same bug for me with ios11. Usage 100%... I tried everything...apple change my iPhone and same problem.
