[Q] heavy battery drain while browsing
I have a huge battery drain while browsing on my sgs2 running CM10 and recently siyah 5 RC1 (before original cm10 kernel). It is hard to find threads like that, there is always talk about wakelocks and other drain issues. So I wrote a new one.
The battery drain surfing the internet over wifi is huge compared to other things I use my phone for. Example:
Streaming a 720p TV show over wireless and watching it on MX player drains about 3x less battery. How is that possible?? I have no problems with wakelocks, the screen on time is usually around 3-4h, BUT, only when using rss and other apps - not touching the browser. There seem to be only a small difference between CM10 original, Firefox and Chrome, perhaps Firefox drains the least, though the power is draining so fast that its hard to compare.
So, is there a way to somehow limit the usage of the CPU or/and GPU while surfing, if this is the problem. Or does anybody have another solution.
As I said, no wakelocks and the battery lasts about 2 days if using apps for getting info-news... + only a little surfing using a browser. I had the same issue on CM9, Slim ROM and others.
