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.
First off, the battery % indicator doesn't seem to increase when on the charger. For example, my wife had 55% battery power when she went to sleep and put the phone on the charger. When she woke up, still 55%. She restarted the phone, which then dropped the battery level to 22% (even though it had been on the charger all night).
Now the phone is randomly restarting by going black, then immediately to the startup screen (white Apple logo). It restarts very often.
Obviously something is very wrong. Could it be that the battery we received was a lemon? I had no trouble with the installation. The phone does make and receive calls, when it's not randomly restarting.
I reinstalled the old "quick to drain" battery, and the problems stopped. The phone no longer randomly restarts, and the battery indicator level (%) does increase while being charged. It's looking like the new battery itself is the issue.
Please help! My wife can't live without her iPhone.
Ist dies eine gute Frage?
