Battery level changing radically

I started playing Clash of Clans with about 40% battery left. Then about 5 minutes in the device alerted about "Low battery charge" and right after that it alerted "Battery is empty. The device will shut down soon".

I closed the game and looked at the battery and it was at 0%. I plugged in the charger and it started to charge, but booted up right after plugging the charger.

When powered off and charging, the phone shows the current level of battery and it showed that battery had 45% charge. I booted up the phone and battery level was at 45%.

There's couple of things I'm wondering. How the battery drained from 40% to 0% in 5 mins and how the device was still powered with 0% battery. I was told that the phone should shut down at 2%.

Detecting the charge level of the battery seems not to be an easy task. Maybe it's useless for this device, but on other devices users adviced to "calibrate" the battery: Use the device until the battery is completely empty, so it shuts down. Charge the battery up to 100% while the device is still turned off, which will last a few hours. This may be an esoteric thing or even hurt the battery, as LiIon batteries do not like to be drained at all.

It happened to me yesterday, I used it quite alot and had a normal consumption level, but then I put it on standby, and just 2 hours later it had lost about 40%, which is insane!
