My SE has been draining quickly the past few days (after updating to 10.2; although it seemed fine the first day after the update). Don't know what's up...

Absolute crap for a couple weeks on my 6.

Today it went to 9%. I plugged it in and it jumped to 64%.

These threads are really pointless. Everyone will have different battery life because everyone has different usage. There are too many variables at play for anyone to really give someone an idea of how battery life is.

This is true, but with that said, no noticeable change here.

My battery life is horrible since updating to 10.2. I actually had to charge my phone yesterday at 5pm. I never charge my phone during the day. I'm always able to make it until I go to bed to charge it and even then it has roughly 15-20% remaining. This update killed my battery :(

I've noticed with iOS 10 in general to have much worse battery life on my 6 Plus. It's also much slower at opening apps, especially when I pull-down on a text message notification to type a response, usually like a 3 or 4 second delay.

Battery drainage seems to escalate over time as well. I recommend restarting every other day, which seems to stop whatever's causing this.

I have a 6 plus that after i upgraded to 10.2 the battery went crazy. Dropping 30 percent in minutes , shutting off with 25 percent and jumping to 30 percent at the start of charging. After a couple of days I down graded back to 10.1.1 and everything is back to normal. The problem is 10.2 not hardware.

However 10.2 does not cause a problem for everyone. I have it on my 7 and my 3 year old 5s with no battery problems on either. Maybe some part of the firmware to do with reading the battery is getting corrupted for some when updating to 10.2?!

Ive been doing updates since the original iphone and this is the first time its adversly affected my phone. All i know is a simple downgrade to 10.1.1 fixed the problem . Im done updating my 6 plus.
Hopefully apple will quit downloading 10.2 to my phone and requesting i update. Ive already deleted 2 of these files

It doesn't matter if you've been updating since the first iPhone or not you have no personal control over whether or not something goes wrong on your handset during the update process and that may have happened. If you don't want to be pestered about updates install the tvOS profile on your phone and you won't get promoted to update again until you delete that profile ;)

I have been having problems the last 36 hrs..with heavy battery drain. It started while i slept and it was plugged in. (went from 100 to 34% while plugged in) I did a restore...looked fine then last night i was looking at YouTube....had 10% left so i plugged in...went up to 15% so i looked at YouTube screen no scrolling no loading all other apps closed.....and while plugged in it began to drop at 1% about every 90secs....

I have a hypothesis of what might be happening to the battery performance on some older devices running 10.2.

The latest iOS seems to have trouble calibrating/reading correctly battery's that are reduced in capacity to their original specification once their capacity is reduced by a certain amount. So where on previous iOS version such as iOS9 you would still have some reduced battery life as the capacity slowly drops through use, with iOS 10 your getting large sudden drops in battery percentage instantly and early shutdowns as it has trouble managing a battery that is now below its original capacity.
I could be completely wrong of course but just a thought

Perhaps something got stuck syncing or running after the update? Have you tried restarting? Perhaps resetting some (or all settings)? Maybe even re-installing if it all continues?

My new iPhone 7 Plus drained 20% over night and the usagetime was pretty much as long as the time i actually slept so something must have been running in the background continuously.

Went back to my old habit of closing every app as soon as i stopped using it from the app switcher. Clearly iOS cant be trusted in handling it themselves right now

I guess the larger display drains the bigger battery on the 7+ More, which is why the battery life is only a little better than the standard 7.
Or perhaps that's more of an average (or even slightly below average) battery life of a 7+ compared to above average battery life of 7.

Quite possibly, although the quoted stats on the Apple site also support my comment I.e 13 hours internet browsing vs 12 hours ;)

There's that too. Although I think under real world circumstances most people's usage and standby numbers often differ from the "laboratory" numbers that appear in marketing listings like that.

Absolutely .. but from what I can see online from other users the Difference is indeed minimal on average as stated by Apple, considering the difference in size of the battery's. This is why I assume it's down to that big sexy screen taking its toll on the bigger battery
