Hi guys, I bought a fairly used Tecno Camon c8 phone from a friend last weekend. The battery was nice and strong, then after two days it started misbehaving. The phone battery started draining very fast, It's taking so long to charge, from 1-100%(5-6hours)...
sometimes I would leave it idle for 2hours and The battery will consume like 30%. Though it's a 3000mah in-built battery. I'm using the BlackBerry playbook charger(very fast) and in fact I've tried different types of charge to charge it yet it's still the same thing...


NB:- I inserted one corrupted 32gb memory card into it to check if it will work few days back then remove it instantly because it doesn't work..Though I once inserted the same MMcard into my old phone (Tecno W3) last month, the same ish happened, then I removed it and then it started working back perfectly.
Could it be the mmcard I inserted into it that caused it ? or virus? or anything?

please help me out guys
