Severe Android OS kernel battery drain
I have a new Note 3 (branded by T-Mobile Czech Republic) and I'm experiencing a severe battery drain. Over 50% of battery power is sucked by "Android OS".
After 14 hrs on battery, it has used 3hrs of CPU power and kept the device awake for 10.5hrs. Gsam is more specific and says it belongs to "Kernel (Android OS)".
Restarting the phone sometimes helps and when it does, the battery time is fantastic.
