Just did a test
2 hrs Internet browsing on edge and one movie
I'm getting the 10% warning
Think it's time to get a replacement sent from rogers
Even turning off location services didn't help
Incase anyone is wondering, auto brightness is turned off
Brightness set to 25-30%
Anyone else think of anything?? Or should I just get this replaced??

It's also an issue about how many and which Apps are running. Many Apps are not 'friendly' in their battery usage - once triggered, never sleep - and many Apps are Apps-centric, considering themselves to be the ONLY thing that is running AND the only thing of any importance! Only one App (the WRONG App) can have massive NEGATIVE impact on battery-life, even if a user thinks that they have not 'really' used it.....
As we know, users are unreliable barometers. As we also know, concentrate on the fixed points of reference: remove ALL Apps from the iPhone, switch off ALL unused services and then see how the battery performs....
Report the usage figures on that basis and it makes comparison easy, otherwise it makes comparison only TOTALLY meaningless!
Remember, Apple will have taken the "best case" readings for the battery life. This means playing a video will be done with no email and in airplane mode with the lowest screen brightness.
I find mail and location services to be the biggest battery killers, especially if the servers you use are not accessable from the internet (iPhone tunrs off wifi when asleep and if the email program trys to fetch it gets stuck in a power sapping loop).
I usually watch a film over my lunch break. I get about 1h of viewing before my battery level drops by one notch so I think i could get 5 or 6 hours out of it.
I have 3G off, email set to manual, location services off and I usually restart the phone every day to kill off any stuck applications that can eat battery as well.
For example my iPhone 3G is currently at about 95% battery charge with a standby time of 1 day 4 hours and a usage of 1 hour 7 minutes on 2G (being mainly outside 3G coverage) with 14 available Apps (12 loaded, none running in background).
I have no problem with battery although my iPhone is left on 24 hours a day, mainly unplugged from any power source (as the 1 day 4 hours standby and 95% battery capacity shows).
An enormous amount of variability seams to appear with people who are using (large?) numbers of questionable-quality Apps which they leave running (rather than ensuring they've terminated then correctly/completely), all of which increase the usage time: if the usage time is high when YOU have not been using the iPhone then maybe you need to ask "Which Apps are using my iPhone's battery when I'm not using my iPhone"?
Sorry about the late reply
Was working in the lab, 16 hr days are a b**ch
anyways I smell a battery recall if this stuff keeps happening with these new iPhone batteries
I tried rogers last night, I was on hold for over 2 hrs before I hung up
Ear was going to fall off if I kept holding it there listening to their music
I will try again later
It's obvious apple has a major bug with apps not closing when they should be causing battery leakage
Also, location services off added a extra half hr to browsing on 2g
But based on results. I'm only getting half the battery life I should be by 2g specifications at 10 hrs
Instead of 3-4 hrs, this phone is a month old is what ****** me off the most
This should be happening at least a 1-2 after I got it
We'll see what rogers does and I will let u know the results if they ever answer the tech support line

It's just a drawback of the iPhone by the looks of it - there's no point having all these features if it needs plugging in every five minutes. I'm surprised by the poor performance of both iPhones - my first gen went faulty twice and on the original, the two replacements and now the 3G, battery was/is pathetic. strange considering the macbook battery lasts for eternity - sort it out Apple!
