Depends on what specs you have activated – how bright the screen is, how long you’re running apps, how loud/ etc. I have the brightness dimmed and not as many push notifications and it lasts almost 2 days.

it all depends on how much you use it. If you use of such is very limited I’ve seen it last longer than 2 days. If you’re playing with it constantly it could last maybe 5 hours?

When I first got mine, I was surprised at how quickly it went, even with the brightness turned down to 50%.

I can get about a day and a half out of mine if I’m lucky, and this is with a medium amount of web/app usage. I’m jaded with the whole iPhone thing anyways, Droid here I come!

I charge mine every other night. What kills my battery is when i have bluetooth, 3G, or wifi on. I only turn them on when I need to and turn them off when i’m done, especially the 3G and bluetooth. because if i don’t, the battery wont last me half a day.

Lasts less than a day if you are using a lot of apps (Fluther included).

I’m lucky if the battery lasted a full day. I spent a lot of time texting and playing with the apps. I had to take the iPhone back to apple, cancel my contract ( which they did ) and go back to my blackberry. Now I have my blackberry with sprint and my itouch with apple.

I thought they were coming out with a new iPhone soon?

If I keep the screen dim mine will last up to 7 hours of continuous use. I also got a Christmas give of a battery extension pack that will re-charge it up to 5 times.

Heat will shorten battery life. When you charge it keep the unit cool – not under blankets, in the sun, or on top of the radiator.
Keep your car charging to a minimum. The output is not as clean as wall unit and the noise is dissipated as heat inside your unit.

I’d wait. The new iPhone will be released in June, 3gs prices will likely drop after that. The new iPhone OS 4.0 (which has multitasking & folders -also released around June) is not meant to run on 3g.

:( Alas- I shall no longer have the “latest and greatest” but truly my 3g answers all my needs and I would recommend waiting as netgrrl says as the prices should drop.

I charge mine every night as I use it in a speaker dock as my alarm clock. I talk on the phone a lot, and will usually get around 5–6 hour of talk time before it hits 10% battery life. But for the most part the battery last through the day.

Agreed with @netgrrl Now is a very bad time to buy an iPhone 3G. Just wait until the new iPhones in June and you could probably get an iPhone 3GS for half the price.

The iPhone eats batteries if used as intended by all the hype and hoopla. Most people I know have to charge theirs daily, and some don’t make it through the day. However, if you are a more moderate user, you might get 1–½ days out of a charge with a new one.

Within a year it’ll go down ~15%; such is the nature of Lithium-ion batteries. Within 2 years, you’ll likely need a replacement battery, but that is true of anything wth LiON batteries.

But with the next revision due out soon, I concur; hold off for now.

I had my 1st iPhone for 2 years & did not get the battery degradation you speak of – certainly it was much better than 15%.

jerv's avatar

@netgrrl That figure is an average. Depending on a few things, it can vary from negligible to 95%. For instance, my Sansa e280 MP3 player is three years old and still has ~80% of it’s capacity whereas my netbook has lost ~10% in just over a year and my old cellphone was under 50% after after 3 years.

Your mileage may vary.
