For anyone new to the thread be sure to go through these steps to address the battery after updating to iOS 5.0.1:


1. Reset all settings (settings app-> general-> reset)


2. Go through initial setup steps (lang, wifi, siri, enable location, etc) and choose setup as new phone (don't worry your apps, data, contacts, mail will still be there). Do NOT restore from iCloud or iTunes (It can copy back corrupt settings)


3. Turn off system location services timezone and iAd


4. Fully discharge battery (until you get the spinning wheel and it shuts off)


5. Fully recharge battery (overnight if possible)


In my experience this improves the Standby battery drain issue significantly in most cases. It reduces drain from 2-4% or more per hr to 0.5% or less. It has worked for many, many users now. If it does not work after a few try's you may have a real battery or hardware issue and should contact Apple. Good Luck!

I have already tried these steps to address the issue as well as many other troubleshooting measures. None work. My battery barely lasts 12 hours, dropping rapidly all day. Just when I think it's having better battery one day, it's terrible again te next. It's not a hardware issue because I have had my 4s replaced 3 times and am still experiencing issues. Unfortunately, the people at the genius bar are quick to trade the hardware and don't want to spend any time trying to look through my phone and figure it if there is a software issue. Apple needs to fix this it's ridiculous.

I've been having the same problem with my iPhone 4. Had no problem with iOS 5.0.0 but as soon as 5.0.1 was released I'm struggling to get my battery to last any more than 6 or 7 hours. Anyway I have just spent an hour on the phone with Apple technical support who in the end have concluded that I have a software issue (no s**t). Official word is that they have been told nothing with regards to a further fix being released. All they have been told is that someone is working on it (lots of information there). Anyway for the time being they have recommended backing up to a computer (not iCloud as they feel iCloud may also be hoarding bugs) and doing a restore then back up directly from computer. I'm in the process of doing so and will report back within the next 6 to 36 hours depending on battery life

Nonsense. It does happene - but it shouldn't.


This is a cultural, leadership issue that involves quality and testing - at the very least. Your giving it a free pass because it's so complicated is exactly the wrong approach and why Apple is in this mess. Testing rigor has dropped and needs to be fixed. If you cannot test it - you should not make it. And this is not some one off weird issue that involves some odd and rare combination of apps and buttons. it should have been found in testing.


As for 5.0.1 making it worse. My guess is they went for solving symptoms and not the root cause. These are all signs of Apple becoming something les than stellar. Which is a shame.
