I have a not so old 7 Plus, circa 7 months old. In the last few days I have started to get quite significant battery drain. For example I went and visited my son this afternoon, when I left home I had circa 90 percent power available, I was away a couple of hours and when I returned I had 39% power. I have noted this rate of discharge over the last week or so. I have not loaded any new Apps and do not have a huge amount of Apps installed. When I checked the battery app there is no significant battery use by any App and the highest usage is being attributed to the Home/Lock screen. I have also noted that the phone is warm, not uncomfortably hot definitely a lot hotter than normal. I do not have a cover on the phone.

 

I am not doing anything different than usual and I have tried power cycling the phone. I have also deleted and repaired the Apple Watch. Are there hidden Apps that do not show in the Battery App that could be draining the battery? Has anyone have any suggestions? I was going to do a reset when IOS11 is released but may have to do it earlier.

 

Any help would be gratefully received.

I've had the odd occassion where my 6s+ chews through power at an alarming rate. 

 

I'm talking a 5% drop every minute, ie, after 10 minutes the power drops from 100% to 50%. 

 

It was fairly temporary though, after a couple of weeks whatever was the issue corrected itself.

Perhaps it’s downloading the 2.2gb of IOS11 ‘in the background’ to load share their servers over a few days before its released? I know updates are automatically downloaded BEFORE you’re asked if you want them and (re)sign the obligatory Apple T&C update each time...

Secondingly this.

We really don't know which app you've installed and have no basis of what you are using the phone for. The only way to be sure is to reset or shift/command+restore the operating system and see if the problem is still there even with no app installed.

Otherwise. I'd start with disabling background process completely and check the location setting in privacy setting so nothing is constantly polling your device to suck down power.

I have noticed similar behaviour on my 7+ over the last few days.  But I'm testing at the moment - drained completely and just about to complete a full charge.  Will see how that lasts under normal use.

I had a similar issue with my 6S+ a few months ago and switched off a whole load of notifications that I didn't even realise I had on.  That seemed to solve it for me and it's now back to normal.

Nothing's changed on my iPhone other than I've been running the iterative versions of the iOS 11 beta.  It's on the GM now.  Most likely it'll be related to that if I do have a problem, otherwise I'm just associating this post with the fact I used more battery than usual the last few days.

Well there it is... Beta IOS almost always affects battery life (and did for me on my own 7+ too) so ideally you either suck it up as a beta experiment or wait till the gold GM (or even the .1 iteration) before having the latest IOS build 😉

I'm not the one who started the thread, I'm just commenting that I've seen similar behaviour lately, and I have no issue with the beta draining battery.  I'm well aware of the risks of running beta software.  However I am on the GM, so it stands to reason if I am having battery drain issues (which I already said I might not be), then a lot of people with 7+ device will be on day one too.

Honestly I'm just shocked that iPhone users have these issues too (coming from an Android user.) I thought your phone didn't get battery issues?

Have you tried calling AppleCare and getting them to run a battery diagnostic?

its going to get worse from here as its almost always the apps e.g. ever since they enabled background app refresh and 'always allow' location service option

stuff like facebook Is getting more and more huge too, to the point it's taking a while to open even on the 7



also protip: do not install the facebook app on ios device. it gives rise to some advanced tracking ability to suggest friends even though you guys have zero mutual friend and were just on the same wifi network or been in the similar area
instead, use the web browser version and just make a shortcut to that on desktop

facebook was also the culprit of bad battery life a while ago because they had a bad update

so even if you are using your iphone 7 plus the exact same way as a week before, badly written apps with its auto app update would still break your battery life
