Numerous posts to the thread for the issue on Apple's support forums complain that the fix has not changed anything. A few people have even said the problem is worse with iOS 5.0.1.
These forum posts do not tell us how effective the fix has been overall. As anyone who has ever worked in a customer service position can tell you, it's much more likely you will hear from angry customers than satisfied customers.
And yet some people have said the problem is fixed, while others have noted a slight improvement. But for every one of those posts to that thread, there are many more complaints:
3gs: with the iOS 5.0 battery was good.
sinds the new update iOS 5.0.1 Battery life is shorter!!
Some people believe it is a hardware problem, and that Apple is aware of the problem but simply doesn't want to admit it:
Yesterday I applied the Fix 5.0.1.
Do you guys remember the "ANTENNAGATE" Fix where Apple was just has changed the display for the signal bars strength? ROFL?
They did it same here with battery.
After I intsalled the 5.0.1 full discharge and recharge, I´s able to hold the 100% up to 25 min talking/surfing/emailing. After that it drops to 98% instantly, then it continues dropping so fast I cant believe!!! Apple just changed the display of the battery status....
There is also speculation that the problem is caused by the antennae:
Battery life was pretty bad on the 5.0
Worse... MUCH worse now on 5.0.1
My best guess is it's the dual antenna, and switching from WIFI to cellular data... iPhone seems to get hung up when neither signal is particularly strong... Anyway - I watched the battery percentage literally count down as I simply surfed basic websites after updating.... Lost 60% total battery in a five hour shift of walking around one small building with the phone in my pocket.
Whatever the problem is, here's what we know. It doesn't affect everyone. In fact it appears to only affect a small minority.
Upgrading to iOS 5.0.1 does help in some, but not all, cases, and may make it worse in others.
