Battery percentage not changing after Rear Housing swap, restarting
Just a background on myself, i work professionally at a repair shop and have multiple years experience on many many devices.
I recently swapped the Rear housing on my iPhone 5 running ios 7 beta 3. I decided to swap to a custom Blue and gold theme and while tedious it was well worth it! The only problem i had was there was one Slotted screw(the one nearest the bottom of the logic board that the battery shield sits on top of)where the screws hole was slightly off, so i had to leave it out until i could reach a better screwdriver. When i turned on the phone everything seemed perfect!!!! But then after about 2-3 minutes a slightly grey tint shot down my LCD and the phone restarted itself. This seemed slightly different than the usual beta restart because of the tint but i figured it was just a bug. The other thing i noticed is that my battery meter/percent doesn't change it's reading until the phone is restarted(whether on it's own or by a person). Everything else on the phone works excellently.
I DID go back in and put in the slotted screw that i had left out and this did NOT fix the problem. Still restarting(but much much less often) and battery percent not changing. i Googled and didn't find anything so i came here!
Does anyone have an idea on what might be causing this?
I know that it could possibly be the battery itself, but the phone is less than 4 days old so i would doubt that. A friend told me to make sure that i transferred over the grounding clip on the charging port to the new phone. I did not replace the charging port and was unaware that there was a ground on the port.
Many have said that it is ios 7 beta, but i was running beta 3 on my previous iphone 5 and never experienced this.
Ideas? Thank you!
UPDATE - The phone also is not recognized by the computer until it is restarted!!!!
