Diablo Update Fixes Battery Drain?
 

I have had battery drain issues on my N810 when I flashed to Diablo. It's been frustrating, since it does not appear to be consistent across all user experiences. According to posts here, it happens to many people but not to everyone.

I installed the Diablo update last week (4.2008.30-2). I have had no battery drain problems since! Something must have been fixed ... at least for me.

What has your experience been -- if you had drain issues?

I've noticed the same thing.

Actually, from what I've been hearing, the update wash pushed mostly for that purpose.

How did you find out earlier than anybody else?

Oops...I just guessed the date wrong. I got it like everybody else.

I too noticed much improved battery life, but it was from a chinook to diablo upgrade.

I have observed something strange recently and I have absolutely no idea if this has been true in past firmware revisions or is related to the power drain issue. When I powered off my n800 last night because the battery was low I had the alarm set. Typically, I wake up 5 minutes before the stupid thing goes off so I didn't worry about it. This morning I woke up as usual and at about 2 minutes before the alarm was set to go off, the N800 actually switched itself on (from a power off state) and the alarm sounded (although not the music file I had previously set). I wonder if the power issue was somehow related to the machine trying to save enough power to allow something like this to happen. And if this is well known or has already been reported than I apologize for wasting your time=)

Probably not. Even when your tablet is "fully off", it draws the tiniest trickle of power to keep time. That way when you turn it back on, it still knows what time it is.

The same hardware that is typically used to keep track of time typically also provides the ability to set alarms, and further usually allows the system to be powered on again based on an alarm.

Not "probably", definitely not. It's yet another cool feature of ARM that it can power on quickly and easy to fire off alarms without impacting the power usage idling for them.

I understand that. What I was specifically wondering is: If, in trying to allow the machine enough power to still wake up, boot and start the alarm (which requires significant power from the non-soft-off), the code to shutdown power threshold had been tweaked with to allow this to happen i.e. a virtual power threshold scheme was (improperly) implemented (maybe only if an alarm was active).....or maybe this feature always existed and I only noticed it now. I've alot of trouble with the alarm after upgrading to Diablo (seems to work properly now...maybe too good). Anyway, it doesn't really matter so I'll just stop rambling
