Hi there. I am currently using a S3 i9300 running Liquidsmooth ROM v2.8. I have noticed that in the battery section, Android OS takes a lot of battery. It is usually in the high 30's and wondered if this was normal or if it was a problem. I get around 3 hours screen on time with Wifi always on and mobile data turned off. Here's some screenshots below. If anyone can help me on how to get better screen-on time or lower the Android OS usage, it would be much appreciated. Thanks in advance.
