Last night I went to bed, having put my N9 on Silent as I always do, but this morning, the phone was off and wouldn't turn on. I connected the charger, and the white battery icon appeared, showing an empty battery! This happened to me a year or so ago with my trusty N900, but back then nobody had an explanation for me. I am perplexed as to why this should happen out of the blue.
From now on, I think I'm going to have to turn it off at bedtime if I need to use it straightaway in the morning (which is 99% likely) as I don't want this happening again.
Yep. I've had it happened. The usual suspects will come in and state that it's something you've installed... but as it stands it's nothing of the sort. I started having problems after PR1.2.
I did have a process hang on me - but even that wasn't the culprit. I had to reflash the device along with the eMMC and that alleviated the problem for me. Now, what it does, I wish I could tell you.
At least you had an indicator that you needed to start it up.
I carpool to work, and generally wait until I get a text message to head outside. Well my N9 was sitting on my desk, full bars, but I got nothing. Tried sending a message to see if someone had slept in, and it wouldn't send. Wouldn't make any calls either. Ended up rebooting, which fixed the issue.
This power drain sometimes happens to me, when it does i know about it because the phone will be hot in the morning; I usually keep it on charge overnight and under the pillow. Even if it is not on charge and the this happens the phone will heat up, it can happen even with no apps open.
Checking the "Idle Consumption" I've seen as much as 320mA being used.
A reboot has always fix it.
I have also noticed that even with no problems the N9 gets warm when under the pillow, something the N900 never does.
I had once this problem (PR 1.2) after having installed 2 new apps. Idle went from 3 mA to 70 mA. I did not remove these apps and this never happened again.
Nope, we've barely heard "boo" from them about that one, let alone any claims of fixes.
Based on a consensus of one thing fixing it (there's others IIRC), someone released a script in the bug-report.
