After updates, you may experience battery drains. It is simple. When you put the phone on charge, wait till it comes to hundred. Do not use it. Keep it idle.

Once it reaches 100%, wait for 15-30 mins and then unplug it. If it gets too hot while charging, disconnect it immediately. This may pose a fire or burn risk. Wait till it cools down (use AC for rapid cool) and then replug it. It can overheat to charge like this. Be careful. Keep checking it.
