iPhone battery drain after screen replacement on standby
The previous owner of this phone said that sometime after they got their screen replaced, their battery drained really bad on standby, I assumed it was the battery and eventually that died and flashed the apple logo. I replaced the battery myself and it is still draining really badly on standby. I have factory restored this phone with iTunes and there are no apps installed and it is still draining. The battery section of iOS doesn’t show anything much either. The battery doesn’t last a full day even on standby and nowhere near the advertised 16 days. The phone doesn’t even feel warm and it’s draining for no apparent reason. Is there anything I can try to get this to work?
