I recently purchased a used S4 through Swappa from XDA user @disasp6. When the phone arrived, the battery was fully discharged. I let my wife use the phone a couple of days while hers was being repaired, and she experienced the battery running completely down and needing a recharge before the end of the day after being 100% in the morning. I then turned the phone off and put it aside for over a week and when I tried to turn it on, the battery was dead.
I tried a test, charging the battery to 100% and pulling the battery out of the phone for 24 hours. The battery retained it's charge. It did lose just a little bit of charge in a 24 hour period, but I was able to top it off with about 10 minutes of charging. I then left it in the phone for 24 hours with the phone turned off, and at the end of 24 hours the battery was fully discharged.
I've never seen a problem like this. Any phone I have ever owned has retained it's full charge when turned off. The phone is running safestrap with Goldfinger 9.0 XXUGNK4. It seems to be running normally. I haven't seen any issues with the phone firmware or its operation in the limited time I have been using it.
Does anyone have any idea what the cause of this could be, or how to troubleshoot the issue?
