How did you achieve this? That's incredible
 
On my 6

Usage 7 hours and 29 mins
Standby 22 hours and 37 mins

Battery 40%

This is about the same as on 8.2

I am planning to drain it until it the phone shuts off.

Horrible. Drains much faster than 8.2 ever did. I've given it 24+ hours and done a Hard Reset twice and still is horrible. Anyone else seeing this happening?

With 8.3 my battery most definitely drains faster.

I voiced this a while back but everybody said their battery life had been unaffected from day one. I fully agree with you.

Oh it's definitely effected using 8.2 for about 2 weeks. On anything before 8.2 I couldn't remember the last time I had completely killed my phone. When using 8.2 I killed my phone about 4 or 5 times in a week. So far 8.3 with a clean restore has been treating me well though, went to sleep with it on 75% with 3.5 hours usage.
 
Terrible on my 6.

12% left.

4:41 usage
1 day 9 hours standby

Full brightness, wifi/bluetooth on, background app refresh disabled.

Mostly safari/messages with somehome and lock screen and facebook usage.

This is my first full drain and will recharge and see where I'm at. This is garbage, I used to get insane battery life until 8.3 which was supposed to be even better from what was described and it's total crap battery life now
 
It should be noted that my battery was horrible after the initial 8.3 OTA. But i restored to a clean device in iTunes and then performed a back up.

Here is the result:

Still with 19% left
 
Stellar on my 5 with a brand-new battery and wifi always on. Signal strength makes all the difference for me. I'd be lucky to be at 70% by noon under light usage up at school where the signal blows chunks.

After three discharge cycles 8.3 on my 6+ is ever so slightly worse than 8.2 but it's minor. The positives of the update outweigh the 10-15 mins I've lost per charge cycle. Having said that, I do wish that I could return to the pre-8.1.2 days of getting 11-12 hours of usage time. These days 10 is the norm, and never over 10.5
 
My iPhone 6 is marginally worse on 8.3 compared to 8.2. Averaging about 30 minutes less.

Could be due to the extra widgets I added after upgrading to 8.3 but I can't be sure.
 
my 2.5 year old iPhone 5 battery life after update to iOS 8.3: is improved. maybe get about 1 more hour out of it per day than before. now good for about 9 hours per day with light usage or 8 hours per day with more heavy usage.

How did you get the screen on time count or are you mistaking 'usage' for screen on time?
 
I must say my battery is overall better than on 8.2. Usually end my day with 30% and about 5 hours of screen on time
 
Guys seriously , just stop making every update's thread about battery life after 3-4 days or even a week of release ... It dosen't make any sense and it won't help for sure . The thing is that you should give it at least 2 or 3 weeks and then you can start complaining , i installed the beta 4 for ios 8.3 since the release ( i guess it was like 3 weeks ago i can't remember ) on my iPhone 6 and it just started to get better and better after every charge cycle so please guys just wait more and use your phone normally and you will see after 2-3 weeks that is even better ( ios 8 beta 4 using right now has the best performance/battery life more than any version i used )

I can never understand these 'wait and see' posts. I can tell during the first charge cycle whether an update has affected my battery.

That's the thing, a single charge or even a few don't tell the whole story (unless there's a truly obvious rather big battery issue specifically in the update, which is quite rare). Even without an update after a month or two or just randomly a few days or cycles will sometimes give me bad usage for whatever reason, while some random few days will give me amazing usage--clearly not tied to an update and kind of meaningless to judge based on those extremes essentially that can and do happen here and there.

Yes, I do agree that some days can inexplicably return worse battery life whilst doing the same things as normal. However, my first charge cycle after getting a new iPhone or clean installing a new version of iOS has always been as good as it gets for me. Even taking the days of random drain into account, it still wouldn't take weeks to form an opinion. A few days at most.

Yes innocent mistake. Must be a former android user.

Yeah that is what I thought but I wasn't sure if there was some app to measure screen on time. After spending years on android it is something I miss.
