who have problems after ios5.0.1 updated?

From what I've read battery issues with the 4S can occur when you setup the phone from an iTunes backup, ie restore all your contacts, photos, settinggs etc from a previous iTunes backup.

There's even a ZDnet article where an iTunes backup from a 4S with battery issues (we'll call it phone 1) is put onto a 4S that previously had no battery issues (we'll call it phone 2) and it causes the phone 2 to have the battery issue. Read it for yourself below;

Instead of restoring from an iTunes backup, try backing up all your content to iCloud, reset you phone to factory default, then restore your files etc from iCloud.

Be aware though that iCloud will only backup 1000 photos, so if you have more you'll lose some!

EDIT: alternatively, before attemtping a full restore via iCloud, try simply resetting all settings. According to the below article it can fix the battery issue. It makes sense that it would help if the problem is caused by a setting that restored according to a previous backup. I've just tried it on mine, fingers crossed yo!

hi...i plan to upgrade my iphone 4.3.5 to the ios 5...so i donnow...after i read your posts and feedbacks, i really think to let old version of ios...can anybody advise me????????????

I would advise you to wait until Apple figures out the problem with the iOS 5. I updated right away and have had nothing but problems. My sister has not yet updated to iOS 5 and her phone works great. She has decided to wait to do the upgrade until Apple gets its act together. If I could, I would gladly go back to 4.3.5, especially since the iOS 5 really does not offer any must-have features.

Did a restore as new phone via dfu mode, then did a fresh resync. And, unbelievably, my battery problems (which I'd previously accepted as a normal iphone niggle) have rectified. Everything is on. (ie location, push notifications, icloud, bluetooth, wifi, siri) and I'm simply amazed because it seems too good to be true. I am still at 98% battery after five hours of heavy usage (ibooks, youtube, calls to work etc). Before I was draining 3% every 15 mins. Only problem I am still having is the mute issue on outbound calls (which was the reason why i did the restore-as-new new iphone in the first place. grrr). In trying to solve on problem I may have inadvertendly solved the battery issue on my phone.

That said I have Battery doctor on my phone I dont know if that's making a difference or whether its the the clean restore.

thx a lot guys.....after all that, i think that i will wait the ios 5.0.2 or 5.1...because i think that the only thing that apple made in the ios 5.0.1 , is to fix battery problem only and extended many bugs in the wifi, sim signal, calls, messages,and other.......regards............

I just fixed the battery issue on my iPhone 4S too!!!

I bought my 4S on the day they launched and since then have had terrible battery life (I setup it up from a iTunes backup of my previous iPhone 4). The battery would drain rapidly throughout the day even whilst in standby, and would be lucky to have 20% battery left after 12 hours.

The fix was easy: I fixed it by simply resetting all settings! As outlined in the link below:

I'm stoked that this worked as it doesn't delete any of your media, contacts, apps or messages. You simply have to reapply various settings once you've performed the reset, such as ringtone, wallpapers, wifi network, etc.

If anybody is still having battery issues with iOS 5 I strongly recommend giving the 'reset all settings' a try.

It cannot fix with my iphone 4s. all 5.0.1 9a406 and 5.1 beta 1 and 2 are *****. Apple *****. Are they trying to make their customers insane? What the **** with the 5.0.1 update????? to fix the battery? NO... to destroy the phone network? YES

Only those who experienced sim card failure know how annoying it is

I can surely say that problem is not solved with the new patch. After having 9A406 patch installed on my 4S, its not better even after that. Mine is a vodafone connection here in Germany and it shows 0 signals at my work and home too :-(

But when I transfer the sim to my nokia E7, it shows me 100% signals all the time. This is the simple proof to say that something has gone wrong with the Iphone4s s/w or h/w.

I wonder why dont these guys do the basic testing?? having 2 receivers for new Iphone 4s doesn't improve anything. APPLE, PLEASE TEST IT BEFORE YOU RELEASE... We CANNOT LIVE in a NOSERVICE WORLD...

DO SOMETHING....

Hi folks, I would like to own APPLE solved this my problem which in fact is quite rare.

A year ago I dreamed of having an iPhone, I wanted more than anything to have an iPhone, it was there that I decided to buy one. The iPhone worked perfectly, was quietly updates until you get the latest update, the IOS 5.0.1 I did the update in the normal process by connecting to iTunes and asking him to do the update, after the process finished I went to activate my iPhone, but it happened a very serious error, the iPhone somehow stopped to read the chip. Took in a nearest Apple store but sellers spoke that should lead to the shop of my carrier, arriving at the store I talked my problem and they will speak to the warranty provided by Apple does not cover problems in update.Until today I could not solve this problem and don't have enough money to buy an iPhone 4 or 4S, since here in Brazil the prices are very high.PLEASE APPLE HELP ME!!!!!!

Hi I have the smae, have up issued the new updates and now can only hear sound when my earphones are plugged in or when on speaker phoned. I have no message alerts, no dialling tone etc

Update on wifi problems. Did all I had listed I was going to do and still not able to connect to wifi router unless within a few feet of router. Today it lists some other wifi routers for a split second, then mine, then they all disappear, then does it again. When it does show my wifi when near router I can logon but only if I am right next to router.

Ya me too!

I m in Canada And Everytime it loses signal, my iPhone 4 running 5.0.1 just goes in a loop of searching and no signal. And when I turn on and off airplane mode, it shows a full signal bar without the carrier name. And this doesn't go away until I reboot.

Hope apple fixes this soon
