    Just wondering what people are getting on 8.4. I think I am draining a lot. Did a full restore as new didn't seem to help. iPhone 6 with T-Mobile. Thank you.

    That looks like great battery to me your not even at 50% and you have 3.5 hrs of usage at this same usage by 10% you should have close to 6 hrs.

    I'm getting 3.5 usage for the entire battery before it dies. I plan to do a 2nd restore of ios8.4

    Thanks just wanted a second look to it. The full restore must have helped.

    I can tell my battery life is down the last couple weeks. My phone is at 63% with 2 hours of usage. It doesn't show usage since last charge, only last 24 hours so I can't get a real sense.

    I would also like to see a listing in there for the Apple Watch to know how much of the battery is used by the Watch communicating with the iPhone. I got my watch 2 weeks ago, so I think that is a big part of it.

    I know some people said the watch cut down on their usage since they now used their phone less, but I am finding my phone is draining faster.

    I'm getting better than 8.3 battery life on my 6 plus. I was getting the opposite but then I disabled Apple music. Have you guys tried disabling Apple music? It may make a difference for you.

    Also make sure iCloud music library is disabled and disable cellular data from the iTunes & App Store settings section.

    I have all of the above disabled and turned off yet I'm still getting about 1.5 hour battery less than 8.3. I actually did a 2nd restore of 8.4 yesterday and today I got just barely 5 hrs of usage just barely before it shut down and usually on 8.3 I was getting easily 6 hours sometimes 6.5 so something is eating my battery and I can't figure out what. I had my battery replaced for free during the iPhone 5 battery recall and I just checked my receipt and it's been a little over a yr so either my battery is going bad or it's 8.4. I wonder if Apple will replace a 3rd battery for free. :rolleyes:

    That's looking pretty average. It all depends on what you are doing. Here is mine. I usually get 7-8. Sometimes 6.5 if I'm really pounding away and I'm outside and the brightness is up.

    Oh and give it a few days and a few cycles and the meter will become more accurate. Right after a restore it appears to drain faster because iOS hasn't "learned" your battery yet.

    Is that a 6 or plus?

    I forgot to mention my usage is probably 95% on screen usage. 6-8 hours is typical real world for all onscreen usage on the regular 6. For the 6plus I think it's closer to 10. Sure if the screen is off and you are on airplane mode listening to music you could get your usage time to say 40hrs!

    I typically get about 10-12 hours usage on my 6+. Same as 8.3.

    I'm getting two hours less battery life on my iPad mini 2 since the last update. Down to 8 hours from 10. And I have Apple Music disabled.

    My week long experience with iOS8.4 on my iPhone 5S = smoother in some areas (sometimes opening a folder would have a minuscule stutter), and battery life (especially idle) seems better.

    This is with all Apple Music disabled (also disabled in Restrictions).

    Seems about the same as 8.3 on my 5S. I got 6 hours yesterday. 65% of battery was consumed on Safari browsing on LTE at 80% brightness. 10% home & lock screen, 6% Yahoo news app, 4% Skype video chat, 2% Line, Gmail, weather app.

    Average of about 8:10 of usage at the 20% warning. This is on an iPhone 6. This includes 2-3 hours of audio playback with the screen off.

    I'm getting the same battery as on 9.0 beta 2. 8.4 is better than 9.0 beta 3 for battery life in my experience.

    I have many features disabled in the interest of improving battery life (eg. background app refresh off, location services off for all but maps/Yelp/Find my iPhone). 1 Push account, rest manual refresh. No widgets, no Facebook. Cellular data on for a few hours a day. I don't know if this actually makes a difference it's just FYI
