5.0.1 update--even worse battery life

Stop complaining about the battery life of iPhone 4S because at least for me thebattery life is very long I use it every day when I come home from school, only 10%so I think there is no problem

Same problem here. I was having battery problems before with my iPhone 4s, but I had them under a bit of control with turning off location services and such. Updated to 5.0.1 yesterday as I was excited to use my iPhone as it's meant to be used, with the features offered to me. I have only listened to music for about an hour today and I am down to 83% from a full charge just 3 hours ago. This is a mobile device. I shouldn't have to be tethered to a computer all day just to keep a charge on my phone.

Same problem. Battery life was fine with update to iOS 5 on Iphone 4. Updated to 5.0.1 yesterday and battery life is significantly worse.

Is this just a display change? Is there any way to revert back? Just bought my wife a 4S yesterday- bad decision?

Yes! I have this problem. I updated my iPhone 4 16GB which had previously *no* battery issues -- and now I see it dropping 10% in 40 minutes with virtually no activity.

I am resetting the settings to see if that might help.

thats great. Thanks for your imput.

What you dont seem to follow here is most people paid hard-earned money for a device that doesnt work as advertised. stay in school.

I updated to 5.0.1 yesterday and my battery life tanked. It was better before I updated. Since this (4S) is my first iPhone I don't know how long the battery life should really be, but my phone drained about 75% of its life in a few hours. I also noticed poor 3G connections where at one time was very good. I also noticed a couple of my apps acting unresposive. Not sure if it's related to the updated ios.

Anyone know if there is an easy way to go back to 5.0 without reformatting the phone.

I downgraded 10 hours ago by setting the iPhone into DFU Mode. You need to download iOS5 before, then do a restore with iTunes by clicking ALT and restore at the same time. Then choose the path to your iOS5 download and here we go. It works as long as the iOS 5 is still signed from apple.

EDIT: iOS 5 isnt signed anymore, means it wont work....

alexfromcologne how did you go back to 5.0.0?

Thank you.

My batterys is actually worse now. I am so frustrated. I have the 4s and updated the system last night. Total fail.

6 hours, competely dead after update and full charge. neither took or placed any calls, sent a few texts, received several emails. All but two location services are off. This is totally not exceptable. Even BLACKBERRY is better than this. This being the most expensive phone on the market it friggin well should work as advertised. I'm pretty sure it's illegal to advertise something for sale that you aren't/can't deliver. I think it's called fraud. With a name like Apple, you'd think someone would want to protect the reputation, not kill it. Two failed phone launches in a row. Can you fix this please....

****, I read just in time that it isnt signed anymore 😐

yes, I am seeing way worse performance on my iphone 4s with 5.0.1.

I am suffering from servers battery drain. Worked great on 5.0 but infinitely worse after upgrade. (iOS 4, 5.0.1)

Well, i dont have the problem and i also buyed it by myself with earned money

Hard reset doesn't help. I was forced to do a hard reset because my phone was frozen on the charger this morning after upgrading last night. My battery life is worse too. (iphone 4s)
