CM9 Stabilization? - Kindle Fire General

Is anyone working on getting CM9 for Kindle Fire stable? Even without HW?

It's pretty stable already.
Be patient!
Its all because the devs work hard.

Its working pretty well for me. Stability on the Energy version seems very good.

I've never tried the Energy themed ROM. What I was using want very stable (crashed alot, random freezes and reboots). I finally want back to CM7.

I tried the Energy CM9 ROM a few days ago. It started off okay. But the next day my KF was completely dead. Wouldn't turn on, not even the LED on the power button. I thought it may be wifi draining it, so it turned it off. But less than 12 hours later, with no use, it died again. From my experience the Energy CM9 ROM is completely unusable.

I'm downloading Energy now so I'm hoping I don't have the same issues.

There is a power off issue when using the available daemon controller. It can be circumvented by using the power button. You can read about it here and in a few other posts in the same thread. It's annoying but no more than that as long as you make sure it's powered off.

battery time just fell off

without doing anything new my battery time just droped off the face of the earth.. its down about 75%. i was getting a full day mixed use now all of a suden im getting 6-8 hours with just a few phone calls.
my awake time is at 16%
I havent done anything new that i can think of.
im using (and have been for awhile) the mugen 1800 extended battery.
trying to think what might be doing it and cant come up with anything i havnt found in the forums already.
you probably downloaded some app that is running in the background continuously. check with a task manager to see what's running, and then try uninstalling some recent apps to test it out.
thats what i was thinking but i cant find anything new running with the task manager

Could just be a bad battery? I'm having same problem, maybe worse with stock battery. I went from 100% down to 15 in like 5 hours just reading my RSS feeds every hour or so. I think I may have fried my battery using it to tether for excessively long periods.
You're not using your phone to tether are you?
Mine is way down this week too. Initially I thought it was Swype, but not so sure anymore because no other users are reporting problems.
Are you using Modaco's rom and kernel ? or any new kernel for that matter? Ever since I switched kernels my battery hasn't made it through the day.

I'm using gbhil's custom kernel and seeing BETTER battery life when used with setCPU (using ondemand setting with 'standby/sleep' profile turned on, and set to 160/480).

No I'm not.. Turned a few more newer apps off and still no good today.. I was at 5% batt left after 9 hours with about 10 minutes web browsing (not wifi) 4 or 5 text messages and about 45 minutes talk time. That's down about 90% from were I was a week ago .
I managed to narrow my problem down to the Taskiller widget. Removed the widget (still running the app full time) and all is well.
Last night I rolled back to before I used a custom Kernel. I rather battery life over speed. I need my phone to last from 6am to at the very least 7pm. I think once people get over the performance boost, we'll see a lot more posts relating to battery issues.

might be that too, i hope not as i love that keyboard. just having it installed shouldn't drain the battery, should it? im on day 2 with the custom kernel and i too noticed more battery drain. at 1pm my hero was fully charged. i only played a bit with the phone and made two short calls and it's down to 86% already at 4pm. i want to roll back but i do like the speed of the new kernel. ill see how it does tonight.

Yeah going back to regular input sucks. Swype was only some leaked beta version, we don't really have right to complain; however, I bet their end product will be much better. I just hope they'll release it as an app and not as part of custom Android phone so we can get it sooner.
figured I woud resurect this thread rather than start a new one.
yesterday I decided to RUU my phone to pull the completely stock apks out of it. after I did that I restored my backup of fresh 1.1 with gbhils kernel and now I am at 90% awake time spare parts shows that "android system" as something keeping it awake. any suggestions on what this could be? could it have something to do with restoring the back up with the kernel over stock without a wipe?

[Q] Cant find a straight awnser..

Been away for a few weeks.. and i havent been able to get a bead on weather anything can be done about the sleeping issue with CM7, ever sence i installed the offical build for CM7 battery life is bad.. i have to leave it off most the time to save the battery for when i want to use it.. and then i dont feel like waiting for it to boot up and everything so i just turn on my computer (boot time from power button to desktop is about 35 seconds)
anyways anything i can do?
i dont really want to leave CM7 due to running netflix =)

It would probably help if you let people know what build you're running.

opps meant to put that...
kernel: 2.6.29-omap1

build: GRI40
The battery life on cm7 is bad but its not as horrible as you are depicting. Just charge it every 1 to 2 nights. Theres a beta in the dev forums running the new kernel version, which i believe should fix the sleep problem.
It's out of beta, every nightly past N82 has .32 kernel support in it, with deep sleep. Battery life is awesome! Just keep in mind that battery life is only improved when the nook color is idle, not when playing 3d intensive games.
Now patiently waiting for a stable release.

[Q] Battery Problems

I recently flashed CM9 on my kindle fire and for some reason, when I put it to charge overnight, it only got to 50% from 3% in 4 hours. Is the kindle just that slow at recharging or is it something else?
What rom are you using?

Um, I really can't say. The Fire charges that slowly but not that slow. It could be your charger (doubtful). You might have a background process causing trouble.
I would say kill all non essential running processes, turn wifi off and try again. If that doesn't work, switch roms. If THAT doesn't work it's probably your charger.
Where are you located? US? Europe?
Sent from my Amazon Kindle Fire using xda premium
Yeah its the same micro usb cable I use for my phone so I dont believe it is that. I turned off wifi so I'll see if that was part of the problem. Something i noticed was when i went to settings and under battery it said "discharging" even thought i had it plugged into my laptop.
Well that's your problem...USB doesn't have enough power to charge the Fire. You have to use the Kindle Fire wall charger.

Yup I got my wall charger and that took care of it. I wouldn't have thought that a standard USB wouldn't be enough to charge it in the normal time frame.
Thanks!

The stock wall charger for the Kindle Fire puts out 1.8A, even a regular phone charger will take a long time since they usually put out around .8A.

In running the same rom and the battery life is awesome, as long add you keep your CPU governor to regular default 600-1200mhz. Stop and kill running background services, and turn off wifi when not in use. You have to let your battery cycle a few times so the rom will get accustomed to your battery

Hi, and what do you think about cm9 reloaded? Im having problems when I'm going to turn off.. Or turn on..
CM 9 reloaded went into SOD too much for me, it drove me crazy. The rom itself its nice, but is too buggy for me. Energy is really great. Battery life, smooth UI, and the wifi problems that other CM9 ROMS have is kept to a minimal

[Q] Battery drains very quickily, charges very slowly

My Nook is suddenly taking about 12+ hours to charge, with the OEM cable and plug. I couldn't get it to charge at all at first. I did finally get it fully charged, and it instantly jumped from 78% battery power to 30%. I had tried to clear the battery thing in recovery mode, which might have made things worse.
It doesn't appear to be going into sleep mode, either, as after the 30% jump, I turned off the screen, and the next morning, it was completely drained. Am I looking at a dying battery?
Using one of the latest CM7 nightlies. The problems started after a few weeks of it working fine with the new ROM.
How old is your nook and is it one of the version 1 or version 2 releases?...I had a version 1 doing the exact same thing. Luckly I was still under Warranty and was able to get a replacement, which is the version that was released mid may of 2011 I think. And it had the 5gb data 1 gb media partition...its bwwn working fine and I'm running the cm 7.2 kang w/ mirage kernel.

Let it completely discharge (screen shuts off and Nook is non-responsive) and then charge it up fully. Any battery problems come after flashing and this method always fixes things.

It's about two (?) years old and version 1. Doubt it's under warranty anymore.

to run the battery fully down im going to just use the Nook Color Stock

CM10 battery life

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.

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.

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

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
