A friend's Motorola Moto G (titan) on Android 5.0.2 (Stock) shows this really weird battery graph. Does anyone know what's going on here or how to fix it?
Strange battery graph
Question
Answer
Since he is stock, unrooted, and non-swappable battery, he may have a faulty battery!
Every battery has a built-in circuit that reports its charge, temperature, and stability. That's why every smartphone battery has 3 or 4 prongs (contact points), rather than just the 2 for positive and negative. Best case scenario his percentage is just reporting incorrectly, worst case he may have an unstable cell that could combust. I would recommend looking up disassembly videos for the phone, and replacing the internal battery if it is accessible.
