After installing the update make sure you reset all setttings. I have done a few updates now and have had much better sucess after settings reset all. Standby drain has been virtually eliminated from 2-4% hr before update. It is located in settings/reset//reset all settings. You loose some wifi and desktop settings, but data, apps, etc remain intact.

Hi all, just posting for some advice regarding a system restore.
It seems as though most people have had success after doing a system restore and setting up as a new phone (when I updates to 5.0.1 I needed to restore but chose iCloud backup instead). I am reluctant to lose too much info, so could someone advise me as to what kind of data would be lost a d what could be recovered from the cloud (not via restore but from my old phone)? I know things like apps and music would have to resynced but that's not a problem.
Thanks
Before doing a system restore, try the steps below. Corrupt system level settings created by an iOS 5 bug in the original release that caused battery recalibration issues, etc. Just installing the update does not fix the issue in most cases (sometime it initially can be worse). You need to clear out those settings and recalibate the battery. For those still having the "standby battery drain" issue follow the procedure below in order. It does fix the problem in most cases.
Go through these steps to address the battery after updating to iOS 5.0.1:
1. Reset all settings (settings app-> general-> reset)
2. Go through initial setup steps (lang, wifi, siri, enable location, etc) and choose "setup as new phone" (don't worry your apps, data, contacts, mail photos, will still be there). At this point, Do NOT restore from iCloud or iTunes (It can copy back corrupt settings)
3. Turn off system location services timezone and iAd
4. Fully discharge battery (till it shuts off with the spinning wheel)
5. Fully recharge battery (overnight if possible)
In my experience this improves the Standby battery drain issue significantly in most cases. It reduces drain from 2-4% or more per hr to 0.5% or less. It has worked for many, many users now. If it does not work after a few try's you may have a real battery or hardware issue and should contact Apple. Good Luck!
My battery is at 47%
Cool, thanks! And your battery life has improved from resetting the network settings?
Sounds good...I'll probably try to reset network settings and see what happens. Has anybody tried resetting location warnings to see if that helped with battery?
Hello David,
Thanks! I appreciate that you took two weeks to confirm your results. I will do the upgrade and follow your advice. Hope my results are good as well.
Regards,
Sanjay
Today's battery life was pretty bad:
2%
Usage: 4 hours, 13 minuets
Standby: 14 hours, 10 minuets.
I just do the upgrade !!!!! I did'nt rest my iphone 🙂
Cleoisis is that with 3G enabled all the time? Please describe your usage.
Sounds good but how much hours would you get with 3G switch enabled all the time? Even while on wifi? Can you test that today ?
Thanks
If i reset all setting, would not I lose my contacts and other applications that are installed on my phone?
David
I reset all the setting and fully charged the phone. But still the batter is losing power quickly. Do I need to wait until this drains out then again fully recharge it?

Anyway, anyhow the phone is not suppose to be tweak...to have better results.
no one have be capable to let the phone doing nothing with it and have 200 hours stanby.....the best i see is 125.
do you know someone that can talk 8 hours in one day :no
watch video or film: anyway or impossible you can acheive 10 hours........
try to web for 8 hours ............in the same day.......impossible.
whe have the half that the specs give for that phone..........in a long run people will forget and use to it.
and will buy the IP5 and that phone will have at least 1900 or 2000mah instead of 1450.
you must turn the phone in a flip phone........or a flop phone that is...........
Ok, I will try it. I guess what do I have to lose? I have all my info backed up on my computer if I should lose anything. I'll let you know how it goes. I charged it to 100% late last night around midnight. Went to bed, checked it at 5am and it was down to 76%. It's ridiculous. I used to charge it before bed and get up in the am to 98% before this stupid update. I made an appt at the Genius bar for Saturday, but maybe I can avoid going. I'll let you guys know. Thanks!
what about the update that send to developpers last year 5.0.2 (5.1)......did not ear nothing?
they are working on the ip5.anyway ..........no way a update will give us 25%more juice.
1650mah is not enought with that processor and IOs5 with all features
