I am using Lenovo P2 having Android 7.0. It having 5100 mah battery. In the battery usage I noticed that the wifi using power even if it turns off. I did a factory reset. But still have the same problem.
I have attached a screenshot after did the below procedures. 1) Turn off wifi 2) Fully charge the phone 3) Restart the phone just after unplug 4) Use the phone more than one day without turn on the wifi. Only use the mobile data.
