My battery drains extremely quickly, it can deplete completely in just over 1 hour. It can even drain faster than the charger can supply.
Here is the battery graph after less than 60 minutes of load (this was playing candy crush saga).
Is this normal behaviour or is there something wrong with my phone?
The numbers in the usage stats don't add up to 100% either, it just says Screen 13%, facebook 8%, candy crush 4%, android system 2%, and a few other little 1% apps.
