Asleep and wake lock?

[drbveb88]

Hi Everyone,

I have noticed a couple of posts where people reference that "their phone goes into deep sleep quickly".... What does this mean exactly and does it depend on the kernel you are using?

Also, what does it mean when someone says "a particular app stays in a wake lock". I saw this when some one was complaining about there battery drainage.

How can you tell if either of these things are happening to your phone?

Thanks for all the help!!!

To answer your second question... I use the better battery stats app to see which apps are causing issues.

Ya, better battery stats is pretty amazing, uses root permissions to dig deep. The amount of info us impressive.
It's a $3 app, but is free for xda members. Thread with download is in the main apps forum.
To answer you, a wake lock is when an application or a system operation pulls the device out of sleep to run causing battery usage. Maps is a huge abuser of this (maps does not just mean Google, other location required apps are categorized under maps).
Sometimes they can be stopped depending on what is causing it, but locating them is the first step.

To answer about the deep sleep you can use CPU Spy from the market. It's a free app and tells you what states your cpu has been in since you reset it's stats. Deep sleep being one of the states.
