sounds like some 3g's out there like to randomly put numbers in some of these fields. may explain some of the out-of-this-world usage and stand by times. I will post mine tonight when its closer to being dead
Got a tip for us?

Needless to say, I was pretty proud.
About 18 hours into a trip, I had realized I had forgotten my charger and put my iPhone into "oh **** i have no backup" mode, and turned wifi off, brightness down, and push off, and manual mail pickup - and it lasted. 3G was on the entire time.
The first 18 hours were medium use - mainly GPS use (lots) and web browsing. No iPod use.
Still though, I was happy.
HERE is my usage -- tempted to take it back, but according to Apple, i should only get 5 hrs of 3G talk time (straight through) or 5 hours of web time w/ 3G - so I guess turning it off, on, off, on and surfing, and checking facebook, and talking etc...uses the power quicker?
Suggestions? Keep it? Send it back? I am thinking keep it, and if it gets annoying call up applecare and have em replace it with in the 1 year warranty period:
3G - ON
Location - OFF
Push - ON
WiFi - OFF
Have you tried to run the battery down until the phone shuts off? I did this 3-4 times in a row the first week and tweaked a few settings,i.e. turn off the 3G because reception is terrible, push set to 1hr, brightness @ 30-40 percent and auto brightness turned off. Nothing that bothers me. I get at least a day and half standby and around 5 hours of usage.
Is it true that conditioning the battery can improve performance? Can anyone point me in the direction of what to do?
Also: I understand people are doing things such as turning 3G off when its not available, GPS off, etc...but doesn't that seem to go against reason? I mean, its a pain to have to constantly turn on off GPS and 3G just to have half normal battery usage!
Here's mine:
3G: ON
Location/GPS:OFF
BT:OFF
WIFI:ON

Over 24 hrs on EDGE
Rest of the time on 3G (10-12 hrs)
Brief Wifi, rest of the time off
GPS off except for a few minute searching for resturants
Brightness at 20-25%
1 hr of Pandora Radio, little ipod use
Some phone calls.
You can see the amt of DATA use.
I noticed that with 24 hrs of EDGE I have nearly full battery. 3G with use drains the battery fairly quickly.
I think 3G of all things is the main culprit for battery drain.

Here's my usage for Day 3. I used it extensively throughout the day. While at work, it was connected to WiFi the entire time. 3G the rest of the time. It syncs to 2 email accounts, set to fetch new email every 15 minutes. I tried the GPS a few times, and played a game for half an hour.
Battery Remaining: less than 10%
Usage: 11 hours, 0 minutes
Standby: 15 hours, 7 minutes
3G: ON
Location/GPS:ON
BT:OFF
WIFI:ON
PUSH: OFF
This is much better than I expected. I would say that the battery life was only slightly worse than the original iPhone. Which is still great considering 3G and location services was on all day.

If you upgraded from the original iPhone and used the backup from that on your 3G when you first synced then it probably transfered over the lifetime timer info.
Total time not always equal to usage + standby
Not sure if you guys have noticed, but I know at least iPod use for example counts as 'usage' obviously, but also counts as 'standby.' Guess the phone thinks that as long as the screen is off and locked, it's in standby mode.
I definitely took my phone off the charger a little over 2 and a half hours ago, and listened to the iPod for a little while (30-40 min) on the way to work. My statistics so far? 2:45 standby, with an hour of usage.

To clear this up. The standby time always counts up and only resets to zero when the phone gets a full charge. Doesn't matter whether you use the phone or not.
Usage time only counts up when the phone is not in standby. Just because the screen is off when the iPod is playing doesn't mean that phone is in standby, it's still in use. Standby is with the screen off and no apps running.
As far as I'm concerned the standby number is useless because the phone should get 300 hours standby according to Apple. It's the usage time that's most important. I was easily getting 6+ hours usage on the first gen phone and barely getting 4-5 on the new phone, and that's with the same settings. I don't use 3G because coverage is terrible, location services and push are off as well.
Battery Death
Just run your phone until "Battery Death" (when it shuts it's self down). Do this several times (I did it 3-5 times) in a row and once a month after that to maintain the conditioning.
I don't use 3G because it is not available where I spend most of my days. Auto brightness is off because to me it is unnecessary and a waste of battery life. Push is on, but set to 30 minute sync's, GPS is always on because the radio only works when you run maps or location programs (I rarely do), wifi always on (I tried turning it off but did not notice enough of a difference in battery life to continue). I use my phone for everything, email, location searches, internet, email, ipod, and once in a while I use it a phone. LOL
Good luck, I hope this helps.

Well I was only getting about 3 hours usage
got a new phone
Well I went to the apple store yesterday,and they gave me a new iPhone no problem......so we will see how this battery lasts I'll keep everyone posted with new screenshots of battery usage
If I was getting 3 hours usage, I would have gone to get a new phone, same as you.
3 hours is unacceptable.
Yeah -- the Apple Soulution is bascially not to turn your phone on.
if you leave the phone off your battery will last forever!!!

Please, you wanna see bad please look at the very first posting,your battery is not that bad
This was right after the 10% warning hit...
3g on
wifi on
location services off
BT off
brightness at about 30% with auto on.
some calls, lots of txting, internet and poker game. no music or vids. Pretty happy with my battery so far I played poker for at least an hour trying to drain the sucker.

I played poker for at least an hour trying to drain the sucker.
Yesterday I got about 7 hours of usage and 10 hours standby, and I hadn't quite hit the 20% mark on the phone. About 5 hours of my usage was watching video.
I'm pleased with my battery life. I'm having to charge every day, but it's because I use it throughout the day.
I'm pleased with my battery life. I'm having to charge every day, but it's because I use it throughout the day.
I just picked up my iPhone a few days ago, but I have to say... I think I got a super battery or something. I leave push/3G/GPS on all day long and I get 5 hours of use and 18 hours of standby before I get the 20% alert and recharge it. I've been trying to drain my battery all the way before fully recharging like I do with all my electronic devices... Last night I had to make a phone call, put it on speaker, and walk around the block using the GPS for nearly an hour before just quitting and charging it around 20%. Perhaps the newer (the phones with 5A347 pre-installed) iPhones are using a different battery? That or you guys must be browsing the web on 3G all day long (which I rarely do). I've noticed longer battery life on the 3G than my G1 iPhone.
Just thought I'd chime in since everything I'd read on these boards prepared me for the worst. My battery life has done nothing but exceed my expectations thus far.

I wasn't going to plug my iPhone in till it was almost dead so I could post a result in this thread, but something happened today I don't understand. Has this happened to anyone?
Yesterday morning when I was leaving for work around 8am, I unplugged my iPhone and it was fully charged. Today when I got to work, I hadn't plugged it in again, I still had about 80% battery charge, over 24 Hours of standby, and a little over an hour of Usage which consisted of 90% phone, 5% WiFi, 5% 3G network data (with push, location service, and 3G all on).
The 5% 3G network data came today at work around lunch, I tried to go into the App Store, I was browsing and the App Store crashed. Then I checked my Usage and it had turned to dashes, and I'm assuming I won't get stats again until I fully charge it.
The weird part is, prior to the crash, I had 80% battery after a full day. After the crash, my battery has gone from 80% to 30% in 5 hours with no Usage at all.
Is this bad, or caused by the crash somehow?

Is this a true fact for li-ion batteries, that the battery life improves after it's gone through its first several full charge cycles? Or is it a generally spread and accepted rumor?
I've read things like li-ion batteries are most stressed at full and no charges and thus shouldn't be deep discharged, but have never seen anywhere that charge capacity improves after first few cycles.
