Replaced iPhone4 battery. Now randomly restarts and battery % broken!

Replaced iPhone4 battery. Now randomly restarts and battery % broken! My wife's iPhone4 (AT&T) battery was draining very quickly so we bought a replacement through iFixIt.com. I followed the steps exactly, and thought I had performed the upgrade perfectly. Now we are running into issues.

"Hi Guys

Before you go and start huffing and puffing about the bad batteries make sure you have some settings disabled first! :P

WiFi - This is the No.1 cause of minimal battery life. A lot of people leave this bad boy on when they aren't even using it, or they don't even realise it is on in the first place. The common mistake people make with this is they presume the WiFi is off when it says

""Not Connected""

WRONG

That purely means it is not connected to a wifi router, it does not mean it is physically turned OFF. It still in fact runs at full battery draining capacity because it is constantly searching for new/old networks to connect to.

To solve this issue, make sure this setting is switched to

""OFF""

NOTE - After you update/restore your iPhone, the default factory settings are enabled and good old WiFi is enabled again. Also try to only use WiFi where there are power supplies to recharge your iPhone with.

Bluetooth - Make sure this sucker is disabled as well. Unless you are in your car using it for handsfree or at home using it for music, KEEP IT OFF.

:)

"Hello,

I just wanted to help anyone out there having the same problem.

I also had the same problem. My phone keeps on restarting even when the charger is plugged. I also noticed that the battery percentage is stuck and no longer displays the correct value. I was searching the internet for a solution but all were saying to replace the battery or reset the phone. I already tried resetting the phone but it didn't work.

Out of frustration, i was just ranting to my friends that my iphone is breaking down. Then one of them suggested to turn off the battery percentage display. This seems to have solved my problem. My phone is no longer restarting and I didn't have to replace the battery.

Give it a try first before replacing the battery or replacing your phone. Might save you some money.

Let me know your feedback.

Cheers!

Kristian"

I got a higher capacity battery and had the problem the same as everyone here. I could only see my phone working as long as i was plugged in as soon as i pulled the plug my phone would turn off. Well I plugged it in and went to settings, general, and press reset all. The problem went away and now I have a 2600mA battery instead of the 1400mA original. I also added an external case,battery with an aditional 2000mA I now I don't need to recharge for about two or three days. Hope this helps.
