Pls for some time now, I noticed that my tecno p6 will start discharging backward to 20% or less after it has initially gotten to over 75% and above.

And most times it will charge to like 55% before phcn power goes off. Then if I start using it, it will only last me up to 45minutes before it will start displaying 15% battery remaining, 10% remaining, ... Till it goes off.

Pls what could be the problem and possible solutions? I hardly use my phone for one hour. Thanks for helping me out.

Your battery is the problem
