Hey guys, I just recently got the unlocked iPhone 5, 32 GB on AT&T gophone prepaid. With the recent posts about battery life I decided to test my own by leaving it on standby overnight. I know the standby time is 200 jrs, I decided to test that myself.

I checked and got 95% battery at 11:45 pm

This is with wi-fi on, celular on (it's not LTE, since I'm on prepaid, I get "4G" which really gets me ~3G speeds)

At 8:10 am I had 91% battery

So in around 7 hrs and 25 mins I lost 4% of battery. Is this considered any good?

Thanks in advance!

I usually lose 2-3% overnight with my i5 so I think you're pretty normal.

It looks good to me; did you have your emails on Push? or anything that would be running over night?

Well I never run the mail app, I usually just check it on Safari. If it matters, I had Facebook, notes, settings, itunes, music, camera, ifunny, and lose it on my multitasking bar. I left Safari with 6 tabs open, and I did not get any notifications at all overnight.

iPhone 5 has a stated standby life of Up to 225 hours. Which means you should be losing, on average, 1% every 2.25 hours (less if you have emails, etc checking in the background).

You lost 4% over 8 and a half hours (give or take) - 8.5/2.25 = ~3.8 - so it'd be bang on spec to lose 4% :)

Thanks for clarifying that for me :). I'm surprised the standby time was more than I expected

8 hrs 25 mins = 505 minutes
95 % - 91 % = 4 % = 0,04
505/0,04 = 12 625 minutes, or 210 hours, or almost nine days.

In other words, pretty much on par with what Apple says regarding standby.

Hmm, I'll try reading the thread before answering next time ;)

I'd say it depends on your cellular reception. At my parent's house with 1-2 bars my battery drops noticeably faster on standby vs my work where I'm within a block of a tower.

I usually lose about 2-5% on Wifi standby during the average of 8 hours overnight.

about the same here. my ipad, ipod or an iphone not currently active on a cell network will only lose maybe 1-2% over 24 hours depending if theres anything active like emails and facebook. i had an old iphone 4 on wifi and freshly restored (no email no cell network) and it stayed at 100% for 3 days just laying on a dresser.

This is really good % decrease.

Me with wifi/3g/data on in do not disturb getting approx 2-3 emails + a text will drop me 2% an hour.

I'm currently in testing phase to see whether it's just something I've set causing it. I typically will get 24-30 hours standby (maybe more) with 5-7hours usage (no music).

Last night turned off cell data (left on wifi) and got a few emails and it dropped 4% in just under 8 hours.

Compare this to when I leave data and wifi on it drops about 10/11% over the same time.

Strange as I live next to a cell tower with full bars all the time so the extra leaving data on drop doesn't make much sense?

Id say I lose around 5-8% but where my phone is at night it is constantly 1 bar to no service so thats why.
