That mostly covers it.

I am having the same issues. I upgraded to Diablo last night on a full battery. set up a few things on the system (OMWeather, GPE) and then went to bed. This morning i noticed it had powered down. I did leave it online, but should have still had power after only 6 hours.

My battery life is BETTER with Diablo than OS2007. I went all weekend without charging.
And that is with WiFi, Bluetooth, RSS feeder, and Gmail checker running.

If it's because of Modest vote/comment on the bug.

WRT Modest - No, I've not even run it (I use webmail isntead).

Have checked Wifi settings aren't set to auto-connect, so if it is, its doing it despite control setup.

I'm glad I'm not the only one, unfortunately its rendering my tablet virtually useless.

I'll run through the other suggestions and see where I get to.

Thanks for the suggestions.

The browser (and anything else with a timer) also stops dyntick from slowing the tick rate. If I leave a browser window open all night the battery will probably be flat the next day.

I haven't noticed this to be "killing" my battery. I have gone for almost 3 days with a SSH session logged in (from my linux laptop). Battery works just fine.

I did find that when I was experiementing with getting bluetooth PAN working, that there was a daemon which seems to be chewing through the battery. I dumped that (for now) and now I have pretty good battery life with Diablo.

You may want to try a real version of top to see what is eating your cycles. You can get a real version (with a real PS too) from:

I renamed the utilities so as to not clash with the built in ones, so run rtop and rps after installing.

I hope this helps,

Nope. I haven't even set it up yet. And my battery life has gone the other way as well.

i bought my unit 2nd hand so the seller installed diablo on it already.. you think i should reflash? when fully charged, does your tablet show (only) "5 hours when in use" on the battery status?

I have a N810 and when fully charged it shows "7 hours when in use".

I think N800 and N810 should have a similar battery charge.
