App qualifier - What does it mean?

[fortytwo]

Have only installed a few apps so far. I've observed that in the list of tablet functions effected by the app "prevents sleep function" is stated. Does this really mean I can't put the tablet to sleep; or that it may wake the tablet for some action on occasion; or..... What does it do to battery conservation?

I've avoided these apps so far, as on most of them I can see no reason the sleep function would play any part in app functionality.

I've also noticed that many of the Marketplace apps are very, and unnecessarily, privacy intrusive. Perhaps to be expected for free apps, but if you pay for them?????

Normally that permission means that the app can prevent the tablet going sleep mode when it needs to ... for example, a downloader application can prevent sleep mode while its downloading a file to avoid cutting the transmission... but if it's made as it must, it will release the "sleep" hook as soon as it finishes downloading and then your tablet should go sleep mode.
