Hi there, i recently had an issue with my phone, i don't know if it's either the battery or the charging port, i tried bringing it to many cell repair shops and no one wants to take a look on it, so i was wondering if there was a way to run any kind of diagnosis on my phone to check if the battery is okay or damaged and some part needs to be replaced... If the only way is opening the phone then i guess I'll have to, but I'm scared of messing something up
