Battery life iPhone 5

Same here.. last 2 nights it sat at 1% for 20-30 minutes of use. All our phones are still calibrating. Nobody should panic.

I'm not saying the i5 battery is great.. just saying it's still too early to tell. :)

It is too early, I've charged, and recharged my battery, from 0% to 100% once so far.
 
Mine just died with 1 day 1 hour of standby and 8 hours of usage. That was pretty heavy usage both wifi and LTE and Bluetooth and GPS. I'm very happy with the battery life.
 
today i have:
3 hours and 38 minutes of used
12 hours and 6 minutes of standby

and I only have used 29% of battery after full charge, i think is great!
 
Maybe we should all report back on this in a month. Your first few days is a horrible time to test battery life.

But if I must play, mine was 60% at 4:30 this afternoon, which makes me happy, because I only need the thing to last a day, then charge at night.

I've dropped from 80% to 44% in an hour on the road. Turn by turn was so bad I had to shut it off until I get a car charger. Anyone else seeing drops this bad?

I used my gps a few days ago. Two hours it went from 90% down to 80%. That's pretty damn good for turn by turn.

My iPhone did the same thing at 1%

It was horrible yesterday, I got less than 3 hours usage on less than 12 hours standby.

Today is much better. 3.5hours usage/8hours standby
 
Terrible battery life on my iPhone 5 so far, down to 20% after 3 hours moderate usage :( and over the 4 minutes since I took the screenshot I'm down to 17%, that's a 3% drop in 4 minutes...

My battery life is great so far! 4hrs 2min usage and 15hrs 56min standby on LTE with 34% battery remaining. I can easily see this lasting nearly the full 11 hours of talk time.

I do need to do a full drain though... I could probably get a little more out of it.
 
i "used to" have the 4 and my wife "still" have the 4S.
The battery seems to be at par with the 4S running on iOS 5.

look at it any way you like, but with 4G LTE, i consider it an improvement.
especially if you have experience with Android phones with those huge screens running on 4G. 8 hours is a luxury.

That's a scary thought - I was hoping for at least a little better :(
 
Anybody else having trouble charging through their Macbooks USB port?

Im not sure if its a different voltage than the previous model, but I was trying to slow down battery drain by plugging in while I worked a bit and noticed it only went up 1% in 1hr of work.

Oh dear! That's bad.. Was the iPhone doing anything at the time? Hotspot maybue?
 
I'm noticing quick drain at first but those last 15% or so go by real slow.

My thinking is you have to go through a few cycles (8-10) and calibrate the battery to see the real life of it and that's not something anyone has done yet since no one has had the phone more than 24-36 hours yet.
 
Display brightness

guys, decrease the display brightness to may be like 10% (if it is set at higher)

that might improve the battery life.

Also drain the battery completely couple of times; then you will see the actual battery life...

waiting for anandtech battery test results. I think on wi-fi it should easily give about 10 hours battery life.
 
I set up as a new phone and I can't be happier with the battery life. Coming from the 4S it's like night and day. Setting up as a new phone and turning off all the BS location services really made my battery life great. Which is good since I only have one charging cable till next week.
 
iOS 6 bug - battery draining, details below

I was also getting terrible battery life after upgrading my 4S with iOS 6.

Turns out there is a bug involving iCloud syncing of Safari.

Take a look in Settings > About > Diagnostics, and look to see if there are a whole bunch of crash reports for the process "webbookmarksd". I had a hundred or more.

This is the process that syncs Safari bookmarks to/from iCloud.
I have found that, after restarting the phone, as long as I don't run Safari, battery life is great - possibly better than the same phone on iOS 5.1.1.

However, as soon as I run Safari, the webbookmarksd process starts to chew up CPU, the phone gets hot, and the battery starts to drain very fast - 10-25% per hour.

Seems as if some kinds of bad bookmark data can keep crashing this process, over and over, so that it keeps trying to complete the sync and never can.

(Come to think of it, I had a similar problem upgrading my old 3GS from IOS 4 to 5.1.1 - except it was a calendar sync bug in that case.)

Turning off iCloud syncing of Safari doesn't help. Neither does force-killing Safari from the multitasking bar. Putting the phone in Airplane Mode helps temporarily, but when you turn Airplane Mode off, it just starts right back up again.

Deleting my Safari bookmarks on my Mac and allowing those changes to sync also hasn't helped. And there appears to be no way to force iCloud's to reset its version of the bookmark database and push empty bookmark sets to the phone and Mac. Unfortunately, because otherwise I could clear everything out, then restore from a backup on the Mac and let a good set of bookmarks sync back over.

I'd be curious to see if anyone else has run into this - there were a few people on the discussions.apple.com forums that had similar issues.
