why is my phone charging so fast?

[AC Question]

My phone usually charges too fast. When I put it to charge 10-15 min after he is fully charged, but if I restart it he goes under 30% and then take another 10-15 min to charge.
Can anyone help me?

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

Thanks. I have an hisense LI37200E and I think the battery is new. However now he charged perfectly and its not doing that problem anymore. He doesn't fail all the times but I'm worried.
