No, most iPhones have no problem, and it's also wrong to think it is just a 4S problem. Even Consumer Reports recently said they could not duplicate the problem. But more people than usual have shorter battery life than they think they should get. Some of this is expectations; if the iPhone is your first smart phone you may be comparing it to a more primitive phone that could go for a week between charges. It's a different world; don't think of the iPhone as a phone; it's a very powerful, pocket-sized computer that can also make phone calls. And it gets battery life comparable to a computer, not a phone. Even if you don't think you are using it the iPhone is doing things in background. If NOTHING is running on the phone battery will drop about 1/2% per hour. This is normal. If you have streaming music apps that you forget to turn off (just exiting to the Home screen does not stop them), you have News apps that update (NY Times, AP, USA Today, etc), you have social networking apps (Facebook, Twitter, Yahoo Messenger, etc) the phone is never idle and will use both battery and bandwidth against your allowance.


But there are also things that can go wrong. At least some of the posts in the threads below describe them, and a few have suggestions on fixing them.

I'm at the end of my rope. Yesterday I wiped my iphone 4s clean and started over, hoping something was running in the background that I could control/fix. To no avail. This morning I had 100% battery and now, two hours later and having not used my phone at ALL, my batter is at 70%. This phone ***** and the fix is needed now. Seems Apple was a little quick out of the gate to have something to sell in 2012. HELP!

If you restore your backup you restored whatever was corrupted in it that was causing the problem. Try a restore WITHOUT reloading the backup. You will probably find that battery life is just fine. Then add your email accounts and test again, and it will still probably be fine. And likewise with apps.


As you can see from the threads I linked to earlier, this is not a 4S problem and it is not an iOS 5.x problem. It has occurred on every model iPhone and every version since the first.
