update problem 640xl dual sim

[WPCentral Question]

I have got lumia 640xl. In morning there was an update I accepted it started updating but accidentally I switched off my wifi and now it is stuck at 20%. I restarted my phone but still it is stuck

Try a Soft Reset... Hold the Volume Down + Power buttons until the phone vibrates and reboots (about 10 seconds).

The battery also drains quickly after the update .... Anyone noticed?
