iPhone 7 battery drain

Hi,


I've recently purchased iPhone 7 and setup with iOS 10.0.1, restoring my Apple ID using laptop from an iPhone 6 which was running iOS 10.0.1 also.


For the past 3 days my iPhone 7 battery has been draining really quickly meaning i'm having to charge my phone at least twice a day and i've been using the phone very sparingly. My behaviors have not changed from Iphone 6 (if anything i'm using apps less due to poor battery drain), but i'm finding the phone battery life to be far worse than my previous iPhone and not acceptable.


I don't use battery intensive apps much such as Music or Pokemon go etc and my highest Battery % drain for past 4 days has been Twitter at 27% then Mail at 16%. i do have location services on for apps whilst using but as i say my general phone behavior has not changed since iPhone 6 and im finding the 7 to be draining very quickly. it also appears to charge slower as well.


Any advice would be appreciated. I'm certain I don't need to run the battery saving ideas that the call centre keep advising me to do.


Thanks

iPhone 7, iOS 10

You also might want to check if your battery gets discharged while your phone is turned OFF.


Yesterday I had to shut my phone down because it kept getting warmer and warmer. When I did, the battery had 41% capacity left. The phone did not cool down while it was turned off. Roundabout two hours later it was impossible to power it up again - because the battery was completely empty.

Unfortunately I didn't get anywhere with sorting my battery issues out. Backup restore didn't work, neither did reset of settings or upgrade to 10.0.2. I've sent my handset back today In exchange for replacement which will hopefully have better battery unit. Resorted back to my iPhone 6 which seems like far superior battery power already in comparison!

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 and volume 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.

Thanks drkcope for this, however my iPhone 7 battery usage and standby have always been different so this isn't the problem with my device.

I Do believe there is something that is definitely running in the backgroun, but it's not being shown within the phone itself.

When I first got the phone, my biggest usage was coming from the message app, which I thought was weird. There is however, a lot going on now within this app itself; gifs and such that can be embedded into a text message. Maybe it's all these moving litttle parts that are to blame.

After 2 weeks dealing with this issue I've become numb to this truth. Maybe one day Apple will release an update that will solve this issue. Until then...happy charging y'all!

Yea, I turned some more stuff off, I'm up to about 7 and a half. Also not noticing much difference between LTE usage or wifi usage. I'm scared to see what kind of battery life this will have if I actually use most of the functionality built in like Siri and background app refresh. 3 hours? I may try to do a reset, and maybe a restore from backup. My last IPhone failed to backup properly so I had to start this phone from scratch.
