I have searched for a good battery for the phone but haven't found any. My phone is still in good condition and operates well. I use it as my secondary device beside oneplus 3. Only problem I face is the battery. It charges very slowly and goes from 70 to 100 in a flash and while discharging I can literally count the percentage dropping. I get around 1 hr sot.
So guys please suggest some workaround. And do suggest which battery I shall use.
