Lenovo A916 bootloop

I have a lenovo A916 running android 4.4.2, and when I power it on it is stuck on the lenovo logo and then keeps restarting endlessly. However, when the phone is being charged and I try to turn it on, it boots up normally. When it is on battery and I power it off and then try to power it on, it is again stuck in a boot loop. I have flashed its stock firmware but it didn’t solve the problem. Maybe its the battery?
