I'm finding with a day of fairly heavy usage I'm pretty low by the time I go to bed and have to recharge the phone. Granted, I've only had it a few days so I'm playing around with it and the apps more than I typically would. How is everyone else finding their battery life with the 3G? any tips to make battery life last longer?

Also, does anyone know if the external battery pack accessories that worked to charge ipods would also work with the iPhone?

Cheers

if you are looking to extend the battery life leave the wifi and bluetooth off when not in use

ive been quite satisfied with the battery life.. after quite heavy usage with the new apps and interweb today, i still got the same if not a few min better than i was gettin on my old iphone.

and as i mentioned in the thread i made, the 20% and 10% warnign indicators are actually accurate now.. which is a big help

I have not got the 3g yet. But updated my 2g to 2.0. Ive noticed an obivous decrease in battery life for it, which as you say can only be attributed to the push email.

One more tip:

Turn location services off (settings/general/).

this seems to be a debated topic but i think push might actually conserve battery life. depends who you ask though.

This is all very interesting, because if you think the average battery is good for about 250 - 300 charges before it loses 30% of it's capacity, you've got to think that the average iPhone user is going to be sending their iPhone back to Apple within a year.

I charge my blackberry (which as a replaceable battery) 2 - 3 times a week so it'll last 2 years maybe, and my iPod once a week (30 hr battery life).

Doesn't convergence just stink?

location services are GPS related

Or as Apple hopes, we upgrade our iPhone once a year. If we do that, no need to worry about battery charges.

I have been surprised by hom much my battery drains over night. This is due to "push" email for exchange over Wifi.

Might have to start shutting it down at night.

Has anyone noticed the battery indicator is way off? It will look like my battery is 25% on the battery indicator, but when I start to charge my phone it is nearer 50% remaining.

Turn off, unless needed all the time...

3G,
WiFi,
Location Services.

When you go to Settings/General/Location Services (on off toggle) and turn it off it stays off until you use a program that requires the gps or radio tower triangulation, once you open, say maps and triangulate your position, location services will be turned back on and stay on.

I seem to get 1 or even 2 extra bars when I turn location services off, I don't know if its GPS interference or just extra power drain causing signal to be less powerful, but having Location Services off on the new iPhone 3G is a must.

Its a pain but can save you up to 50% of your battery life as I have noticed. And if you rarely use maps/GPS then it shouldn't be a big deal.

3G isn't in my area till november so I have that off and don't get to report on that yet. Wifi definitely hurts battery life a lot as well.

I found that just turning off the wifi has made my battery life last three times longer.
