I found time zone setting in location services/system services was constantly using gps. It's been back to normal since I disabled it.

Is this just 4S? It didn't seem to be affecting my 3S.

I think the issues are more user/usage than hardware based.

They are announcing security problems with Siri on our local news. Must be pretty bad, or well known, if our local news is covering it.

You can use Siri when the phone is locked. Easy fix, set the appropriate slider to "OFF" in Passcode Lock settings.

Apple: iPhone battery issue due to iOS 5, fix coming | Apple Talk - CNET News

Interesting.

Update is out today...

Will it improve battery life on the iphone 4 as well as the 4S?

Anyone had issues with Bluetooth headsets sounding muffled?

On a 4 here.

Updated this morning while at 97%.

8 hours later I'm at 91%.

Will see how tommorow goes.

I have a 4S and after the update, Im showing 14 hours, 53 minutes of standby and 4 hours, 12 minutes of usage and I'm at 61 %

my 4s battery is great, even before the update. after the update, i am not noticing anything different. i have been very careful with my settings and so far have been very impressed compared to my 3Gs

streaming radio or playing modern combat 3 runs that battery down to 50% in a very short time but thats to be expected so i dont do those things unless i have access to a charger

I've held off on the update, as I wasn't having any problems that needed fixing. Would like to hear some more reports from you guys.

am now at 25 hours standby and 4:30 usage and am at 45%..

Same here. I always wait for the .1 version.

Well version 5.0.1 came out and I took the plunge. Installed on iPad 2 and iPhone 3GS. Took about 10 minutes on each one and the install was without drama. So far no degradation in battery time.

My battery life on the 4S seems better after the 5.01 update; however, I haven't been able to get the phone to sync to iTunes in 2+ weeks. It seems like an iTunes prob vs the phone but who know. iTunes on Windows is a complete turd and freezes constantly. I've tried WiFi and USB. Ideas?

Maybe try uninstall and reinstall. The current iTunes 64 on Win 7 works better than ever. Actually opens up in a reasonable time these days.

maybe just to ease your mind a bit, ive not had any such trouble and i use windows. i had an iphone 3GS and 4S synched to my windows 7 and XP laptops for several years.

do you reboot your iphone ever? or your computer? is your memory stretched to the limit on your computer? any slow or freeze behavior with itunes on my windows systems usually stems from low memory and space

also, i notice over the years that if you fail to update itunes to the latest version, itunes itself will become problematic after several weeks...could be in my head but ive noticed this for 5 years now with each update

so, update itunes, IOS, reboot computer and iphone and reconnect and see what happens...

I did the update and the first day had terrible battery life then did some tweaks and a reboot and getting 48 hours + on a recharge. Very pleased with the battery life on my iphone4. I'm going for the 4S in April when I can upgrade.
