iPhone 4S 5.0.1 Update Improves Battery w/ Settings Reset

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.

One other note. After the phone reboot just go through the default setup ( i.e lang, wifi, Siri, etc) and choose "setting up new phone". Don't restore. That will just reinstall potential corrupt settings. Your apps and data will still be there as before. Really hope this helps some folks. My personal 4S is sitting @58% after 14hrs and moderate use.

day 2 ... stil seeing very good performance. i charge overnight and after two hrs of mostly standby and one quick phone call this morning, the battery is still holding 99% charge. the only other recommendation, i have for folks still having issues in addition to the steps above, is to do a full discharge of battery after the 5.0.1 update is installed. i did this once shortly after i received the phone, but did not need to after the update. however, i have seen on some other forums that this resolved the issue after the update.

freddy,


you don't really need to completely restore as new phone, but reset all settings in my experience and do a full drain and recharge. it is located settings -> reset -> reset all settings. this clears all the basic settings (i.e. wallpaper network, etc) back to default, but still keeps all of your apps, email and data as they were. when it reboots though choose "setup as new phone" after you go throught the basic questions (i.e. lang, location, siri ) setup. your apps, data will still be there as before.


still midway through my second day (east coast) and after nearly 5 hrs of standby and 30 minutes of data usage, battery is at 93%.


ps: does the mk5 refer to a golf... i have a mk6 tdi

Thanks Davidch...I'm doing a reset. BTW....I noticed my calendar is not syncing anymore! ARGH. I had called apple about this and spent 5 hours on the phone with the high level tech guy. he had manually fixed something on my computer so it would work and thanked me for identifiying a bug. Now that I've updated to IOS5.1 (or whatever number it is), it's not syncing anymore. UGH!

xclo,


sorry to hear that. you are the first out of 7 that i have helped that were having the standby drain that did not work using this specific process to fix. i would suggest trying the reset-all again and be sure to drain the batter completely and do a full recharge. if that does not work, i would suggest taking it into apple store for review.

update end of day 2


my personal iPhone 4S has held a 71% charge after 10.5 hours of standby and and 2hrs of data usage. it has definitely appeared to have fixed the problem for me. another one of the users that i help do the same process early yesterday, has also confirmed similar performance for day 2. they are down around 65% but had another half hour of data usage over me... so very similar overall. it now seems to outperform both of my previous iPhones at the point (Original, 3GS) when they were new.

Hi all, just adding my two cents worth,


5.0.1 seems about the same as 5.0 for me. I did do a rest all settings after getting the phone and I think I'm getting pretty close to what Apple says usage will be.


With most of the time on wifi apart from about 5 hours on 3g here's what I've done - a number of short calls, half a dozen text messages sent and received, read and received about a dozen emails, location based reminders current for about 3 hours, around 2 hours online and using twitter and Facebook, played games for about half an hour, and about half an hour playing with settings and Siri - my usage is:


Standby time = 1 day, 12 hours

Usage time = 4 hours, 50 minutes

Battery left = 39%


FYI

My seetings are:

Mail: iCloud and Gmail accounts both set to 15 minute fetch

iCloud: mail, reminders, contacts, calendars, notes, documents, photo stream

Notifications: phone, messages, reminders, calendar, cnbc, mail, twitter, find friends

Location: maps, siri, weather, reminders, twitter

Sytem services: all off but Mobile Network Search is on.


Will let you know the final result when battery drains.
