Setup as a new iPhone and manually reinstalled all my apps from the App Store and battery life is still pretty bad. Made it about halfway through my day (had classes most of the day, was on wifi nearly all day, and T-Mobile service was decent) of barely using my phone (mostly texting with a very light amount of twitter) and it already hit 1%. Also, brightness was between 20-50% most of the day with a few times when it auto-brightened to 100% when I walked between classes and then dropped back down to about 40% once I was in class.

Probably gonna bring it to the Apple Store later this week for a replacement.

I think we need to add carrier info.

I had mine with me yesterday, on tmo, and my iPhone 4 ran circles are it even as I used it as a phone. I have some low signal stuff on there - it tells you that on the stats. I've turned off most stuff.

I forgot to do a screen when I plugged it in, so snagged one at 98% charged (charging on my air charger, impressive speed!!! An hour back to full!!).

I was at 27% when I plugged it in. Mostly 50/50 4g/LTE in orlando, restored ip4 running ios6 then upgraded apps.

Usage 3h,7m
Standby 10h, 16m

Facebook 34%
Mail (low signal) 23%
Home & lock 10%
Camera 8%
Photos 8%

I'm wondering if there is something with tmo 4g? I don't have LTE here, I will be home most of the day, work tonight. I have to make a variety of phone calls (hey, first day they won't include calling tmo about my number port failing!!).

I will know in a few days if it gets better. I hope it does, because if the 4 was doing better with its issues... This isn't going to go well.

I listed that in my post where I said T-Mobile service was decent and that I was on wifi nearly all day, and thus I was on T-Mobile's wifi network (text, calls, data all going through wifi, almost all day. You can see this if you look in the status bar where it says "T-Mobile Wi-Fi". So, having low signal shouldn't have affected battery life. Not only that, but if the low signal did affect battery life it surely would've shown up in my stats as you suggested, but it did not. All of these reasons lead me to believe that low signal was not a factor in the poor battery life that I'm seeing.
 
Just wondering.. On the apple website where it says the 6 battery should get 10 hours Internet use on 3G, 11 hours on wifi etc.. Is this accurate for real life or are these tests done in very controlled environments? (E.g screen on the lowest, all features turned off).. I'm currently getting about 7/8 hours usage and wondering if I should get it exchanged?

standard settings. https://www.apple.com/uk/iphone/battery.html
 
Okay, I'll try and print screen the battery usage later and then decide wether I'm gonna try and exchange it or not.
 
Wow am I really the only one who actually uses their iPHONE as a phone? Crazy. :eek: ;) :p

Seems you and I are just a handful of dinosaurs around here :p I'm satisfy with the battery life, but the LG G2 I used for the past 6 months does bettery. I could go 3 days on a charge, 4 days if I push it.

So it seems like battery for the 6 is averaging around 5-8 hours of usage, just by looking at this thread? I'm assuming the ones getting around 8 hours are mostly on wifi but Apple still advertises that the IP6 should get 10 hours of LTE browsing. Should people like me who are getting more like 6ish of usage have a reason to be salty with the battery life? I'm going into Apple to get apple care tomorrow and I want to have them check the battery to be sure but should I be expecting them to tell me this is about normal or not? I know Apples estimated usage times are always a bit optimistic but 60% of what they're advertising seems to be a little low.
 
I'm on day two without charging on my iPhone 6 Plus. Currently at 41%. I'm at 8 hours of usage and 1 day 7 hours of standby. Last night I purposefully ran down the battery from about 65% down to 55% (streamed HD videos while using the flashlight) so that it would be at 50% when I started my day. Wanted to see if I could realistically make it to bed time tonight starting at 50% power. When I got up it was at 52% so I left the flashlight on while I was in the shower getting ready and it was at 50% when I left. This phone has a beast of a battery!
 
You're the first I read who has the same (bad) experience as I am having . Please keep posted what Apple is saying to all that.

Maybe there are some faulty phones around....

So I just got back from the Apple Store where they ran some diagnostics and what they said is that the battery looks normal, but there's a definite software problem. She said my standby percentages and the amount of power being used when the phone is idle is unusually high. I told her that I'd done a restore, but since I had restored from a clean backup by using that method that was posted earlier in the thread it didn't come as having done a restore so it looks like I'll have to be doing a full restore meaning I'm going to lose all my messages and pictures. Wonderful.
 
Heres my 6 from yesterday... on LTE/4G all day at the office (Signal is decent but it is redic slow since I work in the middle of downtown Pittsburgh)

Only on WiFi once off of the charger for about 20 minutes in the morning and then back on WiFi around 5pm. Not too bad IMO.

Does 4G draw more battery than LTE on t-mobile? I just don't go many places with LTE that often, and my house is often barely showing 4G.

I won't even ask about edge... which is what I go when I left the house today.

I'm not going to "panic" until a few more days have passed, this is my first day having phone service on it that works, and so i'm just getting started.
 
I was also wondering that, if you get say 6-7 hours on wifi should you speak to Apple? My 6 is about 30-40% brightness, icloud, location, background app refresh etc are all off and today I got 8 hours standby and 6 hours 30 mins usage. I was on wifi for 7 out of the 8 hours my phone lasted so should I speak to Apple/try to exchange it?
 
Correct me if I'm wrong, but doesn't the battery usage screen restart after the full charge is made and not when the phone is unplugged? Therefore, all of these screen shots could be way off if the phone isn't immediately unplugged after a full charge.
 
iPhone 6. Regular day to day usage. This is after I did a full charge/discharge cycle.
[edit] can't upload images from iOS??? :confused:

Are you guys turning off any stuff in location or system preferences? If so What? :)

I never turn location services off (too lazy to micromanage it). It's always on for me. However, anything that I can set to "only when app is running" I set to that. I never use the "always" option as the app could be sitting in the background just watching your location all the time wasting your battery even when you're in another app!

I also turn off Bluetooth and background fetch. Brightness is unchanged from the default auto-brightness.

I've noticed some in my Battery Usage screen. A few apps show "Background Activity", which must certainly be related to Background app refresh. Yet I see apps there which not only are turned off in my background app refresh page, but even don't show there up at all - for example Flipboard. It's not even on the list of background app refresh - yet for some reason, in battery usage it's showing background activity. Does anyone notice something similar?

I saw "Background Activity" in the first day or so I used the phone in stuff like Notes, Photos, and Reminders. I'm guessing it was downloading and syncing all my notes, photos, and reminders from my previous backup on iCloud. I haven't seen it anymore since the 2nd day onwards.

Here is mine. Is this good?
...
For those taking about installing new, do you install completely as new, lose all messages then rebuild your home screen 1 app/bookmark at a time?

Yeah that's how I setup as new. It's annoying having to lose all my iMessages and having to rearrange home screen icons again, but the tradeoff is I get great battery life and less unexplainable or weird issues/bugs.

So this is my result from today . You still think this is great battery life?
I'm seriously thinking about returning it. It's an iPhone 6 64 gb. Wifi all day, 4G Off, Location off, background activities off

Seems pretty bad battery life to me considering you keep all of the big battery eating stuff off. If you keep 4G data off does it connect you to 3G instead or do you get no data at all when it's off?

brought my 6 back to Apple today and they checked my screen shots did some diagnostic? and believed me that I knew what I was talking about and my settings were set beyond appropriately.

New same 6 (increased storage to 128gb) is at 100% and I already feel like it's going to end up having respectable life.

Awesome! I wouldn't have kept your previous phone with such horrible battery life either. I suggest everybody who is still within their 14 day return period to seriously consider returning your iPhone if you can't figure out a software/settings battery life fix within the return period. Don't risk getting stuck with bad hardware that you can't fix yourself! Just return it like meagain did here and buy another iPhone again. I wouldn't even accept an exchange, personally, not for the money we spent on these things.

Update: battery life is still terrible even after restoring as a new phone. Gonna see if I can bring it in to Apple tomorrow for a replacement.

Yikes, maybe you just got unlucky and got a bad one. If you can't fix it by your return deadline I'd return it and get another one.
