Post Body

For the last few days my S5 has been going through more then 1% a minute (ridiculous) with the screen off. Going into settings>battery shows that it has been awake the whole time. In the list of things using the battery, Android OS and Android System are the top - nothing unusual.

I opened up the task manager, nothing using an excessive amount of RAM or CPU. I downloaded greenify and wakelock detector, but I have no idea what I'm looking for...

If I rank by CPU wakelocks:

Google App x675 47m 39s

Cerberus x137 28m 24s

What does this mean?

Please someone tell me how to work out what is causing this as I am literally stuck on the end of a charging cord at present - this battery performance is pathetic.
