CM10 battery life

[yelloguy]

I have had CM10 on my Nook HD for a couple of days now and I am disappointed by the battery life so far. To be honest, it is more a question of being impressed with the battery life on stock ROM than the other way around. Because coming from Nook Color, I was quite impressed by the battery life on Nook HD. In standby, it would go for a week without charging. With moderate usage, it would easily do a couple of days or 3 days even. But with CM10, standby sucks up battery juice like crazy. Overnight I lost about 40% charge. So I am seeing Nook Color battery life on my Nook HD.

This would probably keep me from using it as my daily driver. Since CM10 is so much more useful, I would probably boot to it when I need to do browsing and checking RSS feeds etc. But I think I would have to go back to stock for reading.

Is it the same experience with battery life for others? Thanks.

On stock it shut wifi off when it sleeps, on CM10 you have to go to wifi settings and edit the settings to do the same because it's set to not shut off wifi when sleeping.

I have generally found this true on all my nook devices, Color, Tablet, HD, and HD+. CM10 can just not match stock on battery life.

But I like CM10 so just charge every day.

On stock it shut wifi off when it sleeps, on CM10 you have to go to wifi settings and edit the settings to do the same because it's set to not shut off wifi when sleeping.

That might just be the trick, as I shut off wifi this morning in CM10 at 63% charge and the battery is still holding up at 60% after some four hours.

More testing will reveal if it becomes usable with wifi shutoff.

But Nook Color using CM7.2 had insane battery life. Even better than stock -- way better. I don't know how the developers did it but they put BN developers to shame by getting that good battery life out of that device.

There was a problem with deep sleep on the 12/28 CM10 release. Temporarily reverted to the earlier kernel (B&N binary) which helps some apparently.

i've used 12/19 only and found battery life to be pretty bad when in sleep mode. even with wifi off it wasn't nearly as good on standby as stock/root is. but you do get lots of extra features so you gotta pick which is more important. better sleep or a more powerful tablet.

I am on the 12/29 Linaro build and after posting the original question, I took r1c47's advice and shutoff wifi when not in use. I've had good results since then. I did some reading in Kindle app but my battery was still at 40% from that original charge when I posted the first message here. I just put it up for charging again but I might stick with this build for a long time. I just shut off the wifi when I am reading which is most of the time.

The only (minor) problem is the lack of rotation even after checking the box in settings. And I have not tried playing music or videos so far. But otherwise this build is good for me.

The rotation issue is well known. Just hold the device vertical when you want to rotate and it will. And there are two rotation check boxes in settings. One in display and one in accessibility.

Found last night that I was missing the second check box in settings. Everything peachy now. Thanks much!

I confirm that the battery life is acceptable after turning the wifi off. Is there anyway to make it turn off wifi automatically, though?

thanks

Go to settings, wifi, menu, advanced and choose wifi to never be on with screen off.

I'm quite happy seeing over 2 days (sometimes little over 3) on CM10 12/31 build, shutting down wifi after 5 min inactivity and when off.
However I find it a pita to switch off and on wifi all the time when I resume operation on the device. Is it a known issue, or am I the only one facing this?
Thanks
