Fix: iPhone 7 Battery Draining Fast

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.

Thanks for the help.

The issue is with facebook application. My sister and I bought iPhone 7 at same and she was not using facebook application so she didn't faced this issue but I was facing it because I was using facebook application.

My phone is working fine since the day I deleted facebook application. Now my phone consumes 1-2% battery only overnight (approx. 8hrs) when phone is not being used.

Deleting facebook is the permanent solution for this issue, the issue is not related to iOS 10.

I hope facebook fixes this.

Thanks for the response- I will give it a try and keep you posted! Maybe

dumb question, but how does one uninstall just iCloud for Windows, and not

iTunes...?

🙂

Thanks,

Dave

I exchanged my iPhone 7+ 128gb 3 TIMES, and each time it would do the same thing. It would work great for a few weeks, then start a crazy drain of 6-8% per hour, but ONLY AT WORK. I thought it was an app, then location settings, then... I reset the phone to new over and over, sometimes restoring the backups, sometimes reinstalling everything. I tried everything I could think of for 3 months, and was about to give up.

Then I saw the posts above, and uninstalled iCloud for Windows at work 3 days ago. I did reset my phone again, but since then, no excessive drain. With light use, usually 80+% left at the end of the day! I think this may solve the problem. It wasn't the phone as I've had 3 of them, and it only happened at work- not anywhere else. I'm crossing my fingers that this has permanently solved the problem... Others please post your results below too!

I have some bad news... the battery drain is back today!

Again the "in use" and "standby time" where the same, 8 hours and 5 minutes.

Please Apple i'm hoping you guys are looking into this! It's driving me nuts.

Have you updated iTunes since you removed iCloud for Windows? Just asking because as you may well know, when you update iTunes it brings by default (or at least it does to me) the option to install iCloud for Windows, so just one thing to discard before you enter into panic mode.

Now, there is something else going on as 2 more iPhones at my home have done the same but it was just one day, first was my littler daugther's iPhone 7, she called me saying that she had the same issue, at that point I already knew about iCloud for Windows and have fixed it so it didn't make any sense, so I just told her to put the phone on Airplane Mode, then turn the phone off and on again and once it finish booting up to turn off Airplane mode, it fixed her issue.

So, last week, on Thursday, my other daugther's iPhone 7 plus began doing the same and I simply told her to the steps above and that was it, no more issues.

So as you can see, it has happened even without iCloud for Windows installed, but the only difference is that it gets fixed with a simple reboot and/or Airplane Mode on/off, with the original issue and the one talked about here there was no fix, you could reboot, Airplane mode on/off but nothing fixed it, the only thing that has worked for me for the past 2 weeks after suffering from the issue for a month was uninstalling iCloud for Windows.

Got some bad news too. I unistalled iCloud from my Windows laptop and since there was no battery drain until today.

After 72 mins of normal working, my usage and standby time started to increase together. Did a hard reset, my iPhone 7 seems to be working right now. Also I deleted my Mail and iCloud Drive apps. And what I noticed is when this drain's happening I always stay connected to a Wi-Fi network. And if it happens again, gonna try that airplane mode fix you suggested.

Hi guys, I've been experiencing the same as you are and I'm very disappointed with it. My battery drains so fast. I've called apple care about this since I am not in the country where I purchase the Iphone and having a lot of problems. My battery is draining even if I'm not using it and I did the solutions you have told in this discussion like resetting, restoring, uninstalling icloud for windows but it does the same. I hope we will be able to find a solution about this. Btw is it fixed in IOS 10.3 ? Please let me know. Thanks

Hi, I've still been experiencing battery issues after uninstalling icloud for windows. I've tried resetting twice, rebots, optimazations and still, my battery drains quickly even I'm not using it. I'm very disappointed with my iphone 7. Have it been working well know in IOS 10.3? Please let me know. Thank you

That's a question for Apple, not for me, don't you think?

Like I said, believe it or not, nothing stopped the battery drain, not 3 new phones (4 in total), not any Apple Tech troubleshooting, not a factory reset and setting up as a new phone, nothing, once I entered my work office it began doing it until I left the office in the afternoon. It just stopped that day I didn't turn on my laptop, then I realized that it was something on the laptop and the only thing different has been installing iCloud for Windows so after removing it everything went back to normal, no more battery drain for the past 3 weeks since I Uninstalled it after suffering from it every single day for a month.

Now what do you think it may be if it wasn't iCloud for Windows? ;)

No doubt in my case it was iCloud for Windows causing the drain. Three new phones later now my phone holds a charge all day long under normal and heavy use, and my two iPads which were also draining battery no longer drain battery.

okie let me try once but according to me it was an software issue becoz 10.2 was a very battery bug when I updated to iOS 10.2.1 I dnt face that type of prob, in iOS 10.2 I was able to use Ma ph around 4.5 hrs wit 10 hrs standby but in iOS 10.2.1 I can use upto 6 hrs wit heavy usage n 16-18 hrs standby. But am facing is all this during night standby for 6-8 hrs of sleep battery will loose 12% I have checked for so many time n I hav discussed with apple n submitted in apple care they said there is no issue wit the battery only software problem and one more problem I hav came across when I turn off Ma ph for about 3-4 hrs or 8-10 hrs n then again turn it back on I see there will 15% loss then I cross checked with iPhone 6 in that this type i dint see apple also said that is normal I dnt no wat to do plz help me out with this .

I'm not sure if this will help others, but I believe my issue has been resolved. I had tried everything listed in this forum except the iCloud on Windows because I don't have a Windows computer that I've been logged into. I finally went up to the Apple Store and they were just about to give me a new phone when they suggested doing a DFU to restore. So, we did that while we were there. I'm now 10 days post DFU restore and no signs of issues. I actually just completed a 51 hour cycle without charging (before doing this I was getting about 20 with the same amount of usage). If you're still having issues, I might considered giving this a shot. It's worked so far for me. If I have the problem again I will post an update.
