I have a rooted phone with megatron rom. My phone was sorking perfectly up until 2 weeks ago when it started randomly shutting off and then when turned back on there would be no charge left. The weird part is that all it takes is 20 seconds or less on the charger for it to be back where it was when it shut off, this has me wondering if there is actually something wrong with the battery or if it has to do with the system. Does anyone have a similar experience or some insight into whether an OS reset would solve this problem? Thanks in advance.
