I'm having real issues with both 9.0.2 and 9.1 PB 5 on my iphone 6. More worrying is that my wife is having exactly the same issues on her 5s. Basically seeing battery drain around 50% overnight. I've done all the checks I can think of and have now deleted FB, FB messenger and Instagram to see if these are the culprit. Also, a lot of people have been talking about how FB seems to be bypassing the background app refresh even when disabled.

See I would expect that if I had those apps installed but my day is mainly the music app and safari. And my phone is getting very hot and draining fast.

Regardless, you should never expect that kinda of standby battery drain in that timeframe.

Are you guys truly getting a significant boost in battery life on your iPhone 6 with iOS 9 compared to 8? Apple says up to an hour. Is there any truth in that? Are you actually seeing any real gains in a typical day of usage compared to before or is it about the same? Thanks! (I'm still on 8.4.1 for performance reasons.)

My battery life on beta 5 vs 9.0.2 has gone down.

My battery life is perfect on iOS 9.1 beta 5. I've only compared with my iPhone 5 on the same OS though, never ran iOS 8 on my 6 (just recently upgraded).

iOS 9.1 b5 on iPhone 6 Plus, around 30-40% brightness level consistently, everything except data, wifi, and location services off. I was getting about the same battery life on all other iOS 9 betas. I usually stream videos at 1080p on Youtube (via ProTube), browse on Safari, reddit (via narwhal) and occasionally text.

My battery life on iOS 8 *appears* better (around the same overall, though) than iOS 9 but I'm pretty sure it's because of my phone is just getting older with usage. My phone's current battery capacity is at 91%.

Here are some example screenshots I took when I was running iOS 8, around 6 months ago:




(I don't know why my second screenshot says iPhone has been plugged in, but it was probably insignificant enough to not make a difference in the usage shown)

It was perfectly fine till beta4. The problem started happening only since beta 5. My iPhone 5 overheats and battery drains fast

My battery life on iPhone 6 with iOS 9.1 release is better than ever (average 2.5 days of reasonable professional use).

With that said, I have been through EVERY single Setting on my phone and disabled everything that doesn't benefit me. Things like background app refresh and the many privacy and location settings must be understood and customized to your personal needs or no amount of battery capacity can help you.

By the way, it's a lost cause griping about battery life if you are using social media and chat bloatware on your phone. No amount of tweaking can fix that evil.

Are you on the release version of 9.1?
Yes, upgraded to release version of 9.1 and the problem has persisted.
Podcasts app drains a lot of the battery. Exiting the apps manually instead of leaving them in the background helps but it isn't the same as 9.1 beta 4 and below...

9.0 and 9.0.1 were easily the best for battery life so far as my experience is concerned.
9.0.2 wasn't anywhere near as good and 9.1 is no better.

Odd that people see such differences between versions. Short of major new version updates I rarely see much of a difference in battery life. Each update will give me some better days and some worse days, all averaging out to be more or less about the same.

I've seen other people comment that 9.0.2 wasn't so great for battery life. If you do a clean install, reset all settings and use the same apps/usage pattern as previously then why should the battery life be any different unless there's an inherent problem with the latest update?

Everyday is different even if you do the same exact things in the same exact places at the same exact time (which is already fairly impractical for most). Taking things over a longer term and averaging them out is closer to reality essentially. That said, sure, some people might have some fluctuations here or there because of something, but overall it doesn't seem likely that many (in particular smaller) updates are noticeably/meaningfully affecting battery life.

I consistently get the same usage stats (+/- 30 mins) daily. I'm a creature of habit and yes, occasionally I will be somewhere and using satnav or something but I discount those days from my usage monitoring. I can tell when an update is worse for battery life because those stats are consistently one or two hours less than with the previous version of iOS.

10 hours and 17 minutes of usage and 32 hours standby at 4%. Didn't take screenshot but I should've because I've NEVER seen that with my own eyes. iOS 9.1
