Color Nook Color battery draining too quickly

shibamistress · 11-29-2011, 01:39 AM

So I have a Nook Color that I bought on the Daily Steal (I think it is a refurb) that is running CyanogenMod 7 from the S/D card. It's been great, except for one, really frustrating problem: the battery gets drained way too fast. I can charge it, then not even use it, but let it sit turned off, and when I come back 1-2 days later the battery will be totally drained.

At first we thought this is a wifi issue, so I've been turning off wi-fi manually (though I do have it set to come back on when the NC powers up). It doesn't seem to matter if wi-fi is on or not. I also thought, at first, it was only draining it in sleep mode, but I charged it a couple of days ago and never turned powered the device up, and the battery was still drained. (At least I'm pretty sure it was off, but honestly, I'm sometimes having trouble getting it to power down--I'll think it is off and it is only in sleep mode).

It's really frustrating. Any suggestions?

I have not rooted my NC, but from what I have read this seems to be a bug in CM7 and this problem appears to be solved in CM7.1.
Google a bit for more information.

Yes, there were some versions of CM7 that had high battery usage while in standby. That was a couple of months ago, and the current CM7.1 seems to be very frugal with battery power. I am running it on both my NC and my HTC Desire.

I thought I had the most current version, but I may not, as I actually let my more tech savvy husband do this, rather than doing it myself. I'll google it, and see if I can fix the problem that way.

And thanks--I had a vague sense that I may have come across a reference to this as a problem, but couldn't find it was a search, but I knew someone would know and be able to direct me! You guys are great!

This is happening here, too. I made sure the thing was totally off, charged it, and put it on the shelf. No one used it yesterday. Today I tried to turn it on and it is completely drained. It won't turn on while charging, still get the low battery message.

Is this normal? (I am using the n2a card that I just bought).

Hmmmm.....I may know the answer. I just read that when charging the NC turns itself ON. So when I unplugged it the other day, I should have woke it up and then turned it off.

Sound logical?

shibamistress · 12-30-2011, 09:27 PM

That's pretty much what happened to me: it would turn itself on, including wifi, and stay on and drain the battery.

however, I just shifted to the latest nightly from here: http://download.cyanogenmod.com/?device=encore and it runs fine now. (I guess I have 253) It's not coming on when charging, and the battery is not draining, so I'm pretty happy.

(Except for the fact that I thought this was an upgrade, not a new ROM, and so I didn't back everything up first. Which meant I had to replace everything on the Nook. D'oh! I won't make that mistake again!)

The other thing I did to drain the battery, I thought I was turning it off, but I was only putting it to sleep. I am still learning this thing. I suppose it would be best to just leave it plugged in all night and maybe also anytime its not in use.

I woke up this morning to find that my new Nook Tablet's battery drained overnight for some reason. I had just put an SD card in it the night before, but it's just a regular one and doesn't have any custom firmware on it. Has anyone had this problem before? I'm wondering if putting the Tablet to sleep while a book on the memory card is left open might cause the battery to drain.

My Nook Tablet is fully rooted and the battery was not holding too well.

I installed Juice Defender Plus for either .99 or 1.99 (I forget) and just let it run in default mode.

My battery life is appreciably better now. The App states that it has improved performance by a factor of 1.67.

This "Plus" version allows you to power-tweak settings as well if one really wants to go for the gold in time between charging.

Two things that I have noticed so far that drain my NC's battery:

I installed Moon Phase Pro and from that day on I had to plug it in every night. Noticed this was the problem and uninstalled it. Works as it used to now.

I left my NC very close to my wifi router one night. Big mistake. Never leave it close to your router or extender.

Check in setup, apps, battery, to see whether you have an app that is drying it out.
