7% left.

Brightness about 3/4 with auto dim.
Push, wifi on

Nice. What type of usage? Gaming, email, web, video, ipod? Just trying to get a feel for a comparison.
 
mine has been doing very good. everything is on except bluetooth and i have 2 push email accounts running

Hmmm.. that's incredible. Please do explain what exactly type of usage this is..

I'd guess you'd had several hours of just straight iPod playback or something and not much data-intensive 3G type of stuff?
 
i am really happy with my batt life so far. on my 3gs i had to charge it 2-4 times a day, on iphone 4 i have to charge it only 1. which for me is a great performance improvement. !!! i am happy with it can't say i would not love more juice, but hey ill take what i can :D
 
Battery life is weak...what to try first

Push is off.

(was gonna upload a pic from the usage settings, will have to do that later)
Most of my usage time is twitter or web surfing over wifi (maybe 1/3rd via 3G) - no backgrounded iTunes or pandora.
Phone does sit in the glove of of my car during the day (it stays on).

I dunno, doesn't seem like the battery is all that impressive - I had to charge my 2 yr old 3G every night and this isn't that far off. Also, just while typing this, I've gone from 36 to 34%...I know, isn't much but seems like I can just watch the % go down while I'm web browsing. Like driving a 80s era v8 and watching the gas gauge haha.

I have only synced once, right after opening it up. Did not do a restore from the 3G. What settings should I try to see if I can squeeze more actual usage out of the phone. Most of the time I barely get to 6 hrs (w/ 1.5-2 days of standby).
 
Don't forget folks, it counts your sleep time AS the phone is awake and being used... so subtract your usage time FROM your sleep time.... that will give you your actual sleep time.

Damn apple and trying to make us think we are getting more battery life than we really are.
 
finally got to really put the i4 to the test last night. away from power all day. got 6 hours and 34 minutes of usage down to 1%. insane!! this battery is a monster!!
 
This represents what I believe to be my 6th full charge:

How does mine look like? I'm not really happy with mine because I see other users getting 7 or 8 hrs... Thinking of exchanging my phone
Location service: off
Everything else on
Fetch every 15 mins for 2 email account
40% brightness without auto brightness

Oh and disregard the call time because that's the total call time since I got my phone. Realistically I think I used about 15 mins to 30 for calling

I run my battery down till it shuts itself off. I do this twice, charging to full each time. I will also continue my practice of doing this once a month. One time i had 6hr1m usage on my 3GS. But only once hehe. Usually 4hrs usage.

After my initial back to back I simply stick it on the charger when I got to bed.

I have my brightness set over the 'e' with auto brightness on, push off and email to fetch every hour. Location on. Having Notifications off also had an improvement.


One other thing I've found is that setting the network to EDGE really improves battery life. But it stinks for web usage lol so I only use it when I know I'll be away from a charger for a while.

Thanks for your tips.
Btw I just put my brightness over E and wow it is so dark! lol
 
My first full charge didn't have great results. This is my second charge:

I've noticed that keeping location services off has a big effect - far more than on my old 3G.

Wifi on, 3G on, auto brightness on, fetch every 30mins.
