Question: Fix: iPhone 7 Battery Draining Fast

I FIXED THE SAME PROBLEM ON BATTERY DRAIN ON MY iPHONE 7 PLUS! I had the same problem on my new iPhone 7 Plus 128gb phone running iOS 10.02 and here is how I fixed it!

First of all the way you know you have a problem (and also the way you know you have fixed the problem) is when you go to Settings>General>Battery and scroll all the way down and look at TIME SINCE LAST FALL CHARGE. If your usage time is the same as your standby time you know you have a problem and basically the iPhone is running continuously and not going into standby mode. THIS USUALLY IS BECAUSE AN APP ON YOUR PHONE IS MALFUNCTIONING AND YOUR PHONE IS RUNNING THE APP CONTINUOUSLY. You might get clues to this under the list of apps under BATTERY USAGE on same page but that wasn't helpful to me as it doesn't seem to show which app is running continuously.


Here is what I did to fix the problem and any one of these might fix it and I am not sure which one actually fixed it so here are things to try....

FIRST OF ALL MAKE A GOOD BACKUP BY CONNECTING YOUR iPHONE TO YOUR COMPUTER AND USING ITUNES.

1. If you are running Facebook on your phone then delete it and reinstall it as this app is one of the biggest culprits. Takes 5 minutes and might fix it.

2. Then do a soft reset....the way you do a soft reset on the iPhone 7 or 7 Plus is DIFFERENT THAN PREVIOUS iPHONES. Due to the new home button requiring power to work, Apple has changed the buttons used to force a restart. You now need to hold the wake andvolume down buttons at the same time. After a few seconds of holding in the buttons, the Apple logo will appear on your iPhone's display, indicating it has restarted, and you should be back in business. This takes only a minute or so..

3. I then "Reset all Settings" by going to Settings>General>Reset >Reset all Settings. AGAIN MAKE SURE YOU HAVE A GOOD UP TO DATE BACKUP DONE BEFORE YOU DO THIS. I didn't think this step did much and this doesn't erase content but you lose all your settings like wifi connections and passwords etc so i decided I didn't want to lose them all so then went to next step. This takes about 10 minutes.

4. I then connected my iPhone 7 Plus to my computer and restored my backup with iTunes. This takes an hour or two as I have a lot of apps and data.

5, I then went to Settings and scrolled down and turned off the "Allow Notifications" on each app that I could live without notifications. takes 10 minutes...

6. I then charged my computer fully and VOILA it was fixed and the way I know this is I went to Settings>General>Battery and scroll all the way down and look at TIME SINCE LAST FALL CHARGE and NOW THE STANDBY TIME IS MUCH HIGHER THAN THE USAGE TIME AND THE BATTERY IS WORKING FINE AND NOT DRAINING ANYMORE THAN NORMAL.


Sorry that i don't know exactly which step solved my problem but you can do this all in a couple of hours and it saved me from returning my iPhone! Maybe if others try these steps you could narrow it down and let people know which one worked. Reminder backup your iPhone to your computer before you do any of the major steps above. Hope this helps.

I agree. Please confirm if this is a permanent fix. The same thing happens to me once in a while. I'll go to sleep at 100% and wake up with my phone at 60-70%. Most of the time, this is because I forget to close out of apps before I go to sleep. I've never had this issue when I close out of my apps. But it would be nice to not have to worry about closing everything out before I go to bed.


Much appreciated.

I had the same problem about 2 weeks ago, first I did a restore with an iCloud backup, that didn't help anything.

Than i did a full reinstall from scratch and the problem was solved.. until today, battery standby / usage again the same.

I did reset all settings in the general tab just now, I will keep you posted if it helped.

This is the 4th phone in a row with the same problem. I had a 128GB iPhone 7+ Verizon Model back in October and it worked great for about 2 weeks that I had it, I decided to sell it and bough the Google Pixel XL until December 15th when I got another iPhone 7+, this time a 32GB T-Mobile version (A1784), it worked as expected for 2 weeks then suddenly on Dec. 28th when I got to my office the phone began draining the battery a lot faster than normal and when I checked the battery stats I noticed that the Battery Standby and Usage were increasing at the same rate, without even using the phone.


Confused about it, I even did a factory reset just before I left the office, so when I finally completed the restore process I was out of the office already. So it worked great again, as usual and the next day as soon as I crossed my Office's door the problem began, problem is that once it begins it doesn't stop. Fast Forwarding a week and trying everything possible (only thing that stops the drain is turning on Airplane mode, but then turning all the radios back one by one immediately starts the issue, every single one of them) Apple agreed to a replacement, for my surprise it had the same issue since the first day it arrived.


Tired of this, I asked my daughter to use the new phone and let me use her iPhone 7 that was working great, and as soon as I enter my office it happened again. I got tired of this and thinking that the only phone that didn't have the issue while I used it here was the Verizon one, I decided to buy a 256GB Jet Black iPhone 7 + Verizon version also, and guess what? It does the same. I've done 4 factory resets with different options, restoring a backup, setting as a new phone and installing basic settings, setting and a new phone and not setting anything, and all of them just did the same.


So as you can see, I'm out of ideas here, the only thing sure is that so far it just happens when I'm here at work, so it must be related to signal/towers/bands, but I have about 10 other co-workers with T-mobile and iPhone 6S and iPhone 7 and none of them have the same issue I have so that's what driving me crazy.


One more thing, once I leave the office it goes back to normal, but this is totally unacceptable that I must be re-charging all day decreasing my battery life span by a lot for something that seems to be affecting just me on 4 different phones in the last 3 weeks.


Any other ideas or suggestions? Pleeeeeeease.

same here.


The battery drain happen from time to time. And I can notice the phone quite warm to the touch. Even if I kill all the apps using App Switcher.. it doesnt stop the drain. The only fix is to reboot. After reboot, thing went back to normal... but it will come back maybe weeks later out of blue moon.


I was on a Iphone 7 32Gb... intially thought was my unit specific hardware issue. Just last week, got myself another 7+ 128Gb, and the issue happened again just a week later.


Tried multiple attempts.

1. Restore from iCloud -- doesnt work

2. Reset and Setup as new phone -- doesnt work

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.

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...

Same problem here with my iPhone 7 Plus 256GB Matt Black..

Like everyone it started after 2 weeks, this was in september '16.

Did all the steps above and yes, it worked but after a few days the problem did return.

I did narrow it down to 2 steps to fix it for a few days.

1) hard reset the iPhone by holding down the lock button and Volume down - button.

2) When the iPhone is restarted fill in your passcode and then do a normal restart, holding down only the lock button.

3) Recharge your iPhone to 100% and your good to go for a few days...


I hope apple is going to fix this fast! Returning my iPhone for another one doesn't seem to fix the problem, did I read a lot.
