iOS 6.0.2 update made my battery drain quicker

LOL..

That makes perfect sense and Apple do indeed verify 6.0.1 downgrades.

They do not share your sentiments about it not being a hack though. When I posted detailed instructions on how to do that a few days ago they were taken off the website (and the thread locked) in no time.. Let's see if your comment even makes it past the Apple big brother who is watching...

My sister also got this problem when she had iOS 6.0.2 upgrade. (iPhone 5)

She went to bed with about 80% of phone battery last night. After 9 hours, she woke up and found there was no battery left on her phone.😮

She did turned off most of every applicaitons needed to be close. (Celluar on, but 3G, bluetooth, wifi, most of notification and location are off, no application in used)😕

Just want to share the same problem. 🙂

Solution:

1. Close all of my apps (using the app switcher; double tap home, press and hold an icon, click the red close button)
2. Go to Settings -> General -> Reset -> Reset All Settings. (Does NOT delete apps or any data; just resets network/iOS settings)
3. Wait for phone to restart.
4. Charge it up to 100% and monitor

I did the first step. But I'll try the rest. 🙂
Thank you for advice.

I have the same problem with the batery after update... have done the proking9 solution but it does not work for me :/ Thanks any way.. any other advices and solutions are very welcome. Thanks

make sure after you reset all settings
- turn phone off and back on again
- charge it all the way to 100%, it worked for me.

Apple, FYI: I had to do a full charge twice today, after starting off with 100% at 7 AM. It is not just passed midnight. I used up 300% battery today, and all I did was text, use FB and talk for about 1 hr in total.

I have the iPhone 5 and I am still on 6.0 and I have a terrific battery. I unplugged at 6:30am and when I went to bed at 11pm I still had 70% Not a lot of usage that day but still had a little web browsing, phone use, texting and a couple games played. I had a iPhone 5 that was defective and I had updated to iOS 6.0.1 and saw a decrease in battery life, when I got my new iPhone 5 I refused to update and I am still rocking a nice battery. Just got 24 hours yesterday and still had 18% left

iv'e updated to ios 6.0.2 and my battery drainning very fast 😟

I have the same problem. After iOs 6.0.2 my battery drains quicker. Sometimes the battery drains with the phone locked at night, like Phicha_s' sister phone. Before the update i have no problem at all.

I have discovered a no-solution to the problem. If i select "Plane mode" the battery stops draining. But then i have a iPDA, not an iPhone 😟

Before some research i found that with iOs 6.0.2 the phone have some trouble with 3G signal. If you put the iPhone in a place with weak signal sometimes the phone start to drain battery. If you let the phone in a place with strong signal then there is no problem.

I followed the procedure that proking suggested. Slight pain having to reset many settings I had in my phone. However, I did this 3 hours ago and my battery % has been at 78% with no drop. Phone has been sitting idle most of that time. Thanks proking.

Upgraded to iOS 6.1 and issue is solved!!!

same here 🙂

Testing my iPhone with diferents settings last week i discovery some interesting things.

If turn the 3G off the phone have the same problem, but reduced leakage.

If turn Data off then leakage stops and still can send/receive calls 🙂

Now i'm sure it's a problem with some app/service that uses data without control.

Now i go to try reset settings first and then install iOS 6.1.
