G4 damaged battery?

My g4 charges from 5%-100% in 1:15-1:30 hours unlike when it was new which reaches 2hrs. On deep sleep it drains the battery quickly too and I don't know what is the cause of it. Unlike on my g2 which drains 3-5% only on deep sleep(6-8hrs) with WiFi on. Also when I'm using it, max SOT is 2:30-3hrs only with 30mins of simple gaming only.
