My phone battery time is not good and sonetimes my phone acts strange.

[AC Question]

My phone charges quivkly to 100% and stops charging. When i start using it it runs very fine untill it reaches 59% and shuts down as if battery is empty. And then i again put it to charging and it shows that battery is 0%. Sometimes when its charged to 100 and i restart it the battery level falls to 86%. Sometimes when i put it to charging the battery sign keeps blinking. Sometiems a blue screen is seen when its turned on. When i put it to charging in my car it says "unable to charge your phone make sure you are using a samaung compatible battery and charger. The model is Samsung Galaxy Grand 2 and it has a 2600 mah battery. What should i do??

Welcome to the forums. It's possible that the battery is starting to fail. Have you already tried replacing it for a new one?
