What kind of battery life are you guys getting? I"ve got an 8gb 3g iPhone, and i've been keeping it plugged in most of the time, i had my phone on standby last night, fully charged, and by this morning 60% of the battery was gone..

I'm not in a 3g area, but i did have WiFi on, i'm guessing if i turn WiFi off when i'm not using it at home/work or a hotspot it will save battery life.

I had about 75% charge last night and when I woke up my battery was in the red. I had wifi turned off. The battery life so far is pretty pathetic compared to my Treo 700 which I thought was bad. Apparently you have to leave your iPhone on a charger all the time.

i got 5 hrs of usage if its HEAVY internet.
if its a typical day which consists of mostly internet, some app games, some ipod, some calls. i get about 5 hrs and 50min and sometimes a bit over 6 hrs of usage.

i keep push off since using nuevasync doesn't require it for calendar sync.. i have fetch set at 30 min for email.. brightness is set low at about 25% full which is plenty.

whats the point of having a cell phone if u keep it plugged in all day.

i use the phone heavily and it lasts me the day. i don't understand what you guys are doing to cause it to drain so fast.

The reason why I have a cellphone is I have a businesss to run, and am not in my office all the time, but when I am im sure to always keep it charged, when I am out on the road I get all my calls forwarded from the office to my cellphone...also ive used my phone for GPS in some cases thats my point of keeping it plugged in...i use it for managing not only my businesss but a schedule buddy

you're killing your battery if you keep it plugged in all the time when it's already at 100% charge. it's not like a desktop PC people.

there was a long thread about this before.. seeing as i just woke up, i'll leave that up to you people to find it.. =P

Apple thought of this as such a great issue that they even put up a "battery" page on their official site. something like Apple.com/battery or something...

Did you turn 3G off? If you are not in the area then turn it off so the phone stops searching for 3G signal. This will kill your battery quick. I put my phone in standbye at night with just edge going. No wifi, no 3G, no bluetooth and my battery indicator is the same in the morning.

Yeah i already turned 3g off, as i do not live in a 3g area. i'll try turning WiFi off at night as well and see what happens.

Double that - I get approx 5 hours with heavy internet and games and approx 30hrs standby time plus. I turn off my WiFi when no need, no push data and brightness is about 25% with auto feature disabled. I do not start bluetooth till I need it in the car.

I've got a Black 16GB and I'm on my second day of a single overnight charge. Granted I'm at 20% right now, but I've been using it fairly often for calls, music and apps. Not too shabby. :laugh2:

If your phone is draining that much on Standby, one thing that you might not be able to fix is just having the phone in an area where you have a weak signal, be it 3G OR Edge. If your phone keeps switching into No Service or something during the night and struggling to keep a signal, it'll kill the battery. This is true of any and every cell phone.

When my iPhone is on Standby at night, I turn off 3G, Wifi (actually, sometimes I leave this on at night -- I don't think this matters because I have an AirPort router about ten feet from the phone), GPS, Bluetooth, Push and Auto-Fetch. My phone almost never loses any battery power overnight.

There is a site www.mophie.com. They have some spendy battery packs for the iPhone, but don't have one developed for the 3G quite yet. May be an alternative for the future

I purchased an iPhone last Saturday and the battery life just didn't seem good to me. I took it to the AT&T store and they said that I needed to return that phone to the Apple store. I did that yesterday and got a new iPhone. I charged it all last night, via my computer.

I unplugged it this morning and right now it is about 11:28 CDT and the battery is showing about half remaining. I've made two phone calls on it today, at the most, no texting, nothing.

Do I have another stinker of an iPhone or is this normal?

Was it fully charged when you unplugged this morning? Make sure you don't have a faulty USB port and that the phone is really charging.
If it was fully charged, sounds like you need to return this one also.

It happens sometimes that the phone will discharge quite fast, usually this happens when some application doesn't shut down properly (IMO).

Rebooting usually brings it back to normal discharge levels.

The 3.0 update brings (will bring) some noticeable battery life improvements, nothing astounding, but every extra minute counts :)

There are a few things you can do to improve battery life. Turn auto-brightness off. I turn my brightness down to an acceptable level, then turn auto off. Turn off Location Services until you need it. Turn off Bluetooth and WiFi until you need to use them. Make sure if you listen to music that you completely turn off the ipod feature by holding down the Home button until the Home screen appears.
