Help Wakelock questions

[John P]

Hi, I have a few questions regarding various wakelocks that I hope somebody will be able to advise on. Whether they are normal or not Im not sure.

I'm in the UK, my phone is a standard GS3, ie not routed or anything. I had battery life problems but have used Better Battery Stats and GSAM Battery Monitor and found the problem so now all is well and the battery is lasting exceptionally well indeed.
Whilst spending hours finding the original battery drain problem and removing the rogue apps, I came across these and just wondered; are they normal, is there anything I can do to improve them?

1) Android system - Seems to be causing quite a lot of wake locks, particularly running a lot are the Accelerometer, gyroscope & light. What exactly are they, and is it normal for them to be running a lot and cause wakelocks?

2) Facebook - I have turned sync frequency and notifications to 'Never' within the app, and set to not sync contacts, yet its still always in my list of running applications and causing wakelocks. Why? Is that normal, and what can I do to stop it? I only want it to turn on and refresh when I use it (very rarely) - which is what I have set it to. But it keeps running and starting itself even after I force stop it.

Thanks, John

1. The gyroscope might be caused by a bug in Google Chrome if you use that? Go into Chrome, settings, developer options and turn off "tilt to scroll."

2. If you log out of Facebook it should help.

Thanks matttye, I don't have chrome installed no. Is that what the gyroscope does then, works out whether the phone is level. I shall go though my other apps and see which has this feature.

Do you by any chance no what 'Light' is within the android system?

Thanks, John
