My battery life has been sucking on my 3Gs lately too (it wasn't great before either) and can't even make it through a full day even though wifi and BT are off...I gave my wife my 2G iPhone and she doesn't even have to charge it every day if she doesn't want...maybe i shouldn't have upgraded.
 
One thought; Could it be related to the "Remote Lock" in MobileMe? Turning off Location Services seems to have dramatically improved life.... It wasn't a problem before...
 
Well good news, I got a replacement for my 3G. Took a while to convince them to replace it but they finally did. They will replace your phone if the max usage they calculate is less than 5 hours. I was at 5 hours and 6 minutes, so he wouldn't replace it but then he noticed a sound bug about the unlock sounds were too faint and so was my speaker phone.

I'm happy now :D

Thats great, wish me luck, I have an appointment at the Genius bar and need them to explain to me how a 5 minute phone call on a fully battery leaves me with 2/3 rds of a battery.

Goodluck! That shouldn't be too big of a problem.. They plug the phone in, pull up battery stats and then they let you know what they see. Goodluck though! :)
 
I have noticed that I haven't been getting the "phone has been plugged in" message. You know if your phone is at say 60% and you plug it in for 30 mins or so then it would say that it had been plugged in but it no longer does this. Is this a normal 3.1 thing or is there something weird going on with my phone.

Where would it say that your phone has been plugged in? I have no memory of such a message on the iphone :confused:
 
Hi,

Just did a 3.1 upgrade. I think you should leave in charging state and connected to Wireless with Safari launched. The device is supposed to download some data from the internet after the upgrade and leaving it off the charging state will drain the battery.

Initially, my battery drained quickly but after going thru the above, it has stabalized.

Good luck!




:confused:

experienced this battery issue right after iPhone 3.1 update, so i decided to restore as new phone this morning and use it without changing anything, didn't even add email accounts or applications and still experiencing same issues.

At this time my phone is practically unusable what so ever! tried turning off and on, clearing all settings, etc etc with no luck. Any tips or help would be appreciated

32GB iPhone 3GS
 
I beg to differ...especially after sitting overnight and through most of the next morning on idle ( If I remember right, that particular battery cycle was mostly spent playing games, surfing safari, and a little facebook and myspace). From what Ive seen since I joined macrumors, I'd say thats pretty decent compared to others complaints of crappy battery life.

mate I didn't say it was the worst. I said below average. Read the main battery thread and you will see people are getting battery life way better than yours with everything enabled.

My battery life is so average as well on 3.1. I max out at 5.5hrs usage but that is with everything enabled. Push notification, MobileMe, wifi...
 
The issue is 3.1

My partner and I both have 8gb 3g's, Mine is from the day of release last year, never had issues, always been a great battery etc, My partners is a few months old, never had issues.

We both now struggle to get a day.

I also have been having my phone randomly shutting off, only able to turn on with a reset(both buttons held). Did a restore tonight, fingers crossed this fixes the crashing, and fingers crossed Apple get their **** together and fix the battery life.

It would be in the Usage section, Where it shows Usage and Stand By if you plugged the iPhone in for a short time without it fully charging the phone back up it would tell you that the iPhone had been plugged in since it's last full charge(thus keeping it from showing inflated usage numbers). I haven't seen that message since 3.1.

How is this for battery life? It's basically Internet browsing on wifi and some Twitter use on edge. I never turn off wifi though, even when it's not connected (approx 8 hours today). I played a couple games but none graphically intensive. A lot of Tweetie and Facebook.

I ask because when I set my 3gs (where these stats came from) up whe. I got it, I restored from my iPod touch backup. I wonder if I would get better life if I set up as a new phone. But don't want to take the time to screw with restoring it if I'm not going to gain anything. As it is now, the battery life is livable, but I'd like it to be better.
