I've only had my Xoom for a day, havent had a chance to use it much. So far there are a few minor problems, but one is really bugging me. The battery level is constantly changing from 100% to what I can only guess is the actual level. Most of the time it reads 100%, but for whatever reason sometimes it will briefly show the actual level for awhile, then back to 100%.
I did some searching and couldn't find anyone talking about this problem, any idea what it is or how to remedy it?

That is odd. Unplugged, it switches to a lower number then back up to 100% again? Did you install any battery apps or monitoring tools?

Not at first. I watched it happen for awhile then I installed a gauge to see what it would do, and it matches the stock battery meter perfectly.

Looks like your Xoom actually came with a magical unicorn inside that chargers it with magic dust...lol, j/k. But I wish mine had a unicorn.
I say drain the battery, recharge and see if that does anything..or just exchange it.
Been sitting here using it for awhile, and it seems to be time based. I would say 5ish minutes at 100%, then it changes to the actual % (which has been going down) then back to 100% in about 1 or 2 minutes.
I'm going to kill it, then charge it while its off and see what happens. I guess we have no way yet to delete the battery stats?

Killed the battery last night, charged it fully while it was off. Same problem. I guess the next step is a factory reset, then if that doesn't work its going back.
Sent from my Xoom using XDA Premium App
Factory reset didn't help either. I also noticed that the charge light isn't showing the right colors while charging, it just stays white. Guess I'm going to return this thing for another one.
The manual is incorrect re: charging colors. It is just white and only when off. It will turn green if off and fully charged, but there is no red and none of the percentage variations.
Where are you looking at the battery level? Are you keeping the little window in the lower left hand corner open?

Actually just returned it, the new one is charging now, haven't turned it on.
It didn't matter where you looked at the battery level. I looked at the notification area, and the setting/status area. Every couple of minutes it would switch between 100% and actual %. Also, when it was plugged in, when it switched to 100%, it would say charged, and wouldn't charge.
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?

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

I have been using a new ICS build and wanted to warn everyone about the shutdown problems. It seems that by choosing to shut down by pushing the button and choosing "shut down" leaves the backlight running (you can see it if you look).
This has drained my battery down to nothing preventing my Kindle from booting. The stock charger did nothing, no charge, no light, no boot. Plugging in to the PC made the Kindle come on, but reboot after a couple seconds, not long enough for me to even get into recovery mode.
On a hunch I used my phone charger. Not only did the Kindle kick on and boot, but it seems to be slowly charging. I restored back to the stock ROM and now it seems like the stock charger has no effect at all.
Just be careful and be aware that the back light will stay on for now until the kernel is updated.
Thanks!

It happened to me already, but it woke up with the original charger.
Thanks!
yeah two known bugs for the 3.0 kernal are usb wall charging and the device not shutting all the way off (backlight stays on). if you need to you can always go into recovery to charge up. also turning lockscreen and touch sounds off in settings>sound will help save battery
It's 2 different bugs that can combine in a bad way: quick battery drain and loss of wall charger.
Anyways there is hope, people have been grabbing a USB charger form other devices or for most the USB-PC route still charges.
The ROMs are getting very good, the banding is fixed and it seems the AC charger issues have been patched up, even the small menu buttons are fixed in one of the ROMs. Now all I need is a volume bar and I will have my daily driver for a while.
This just happened to me...
My kindle died after shutting down for one day. No battery at all...
Did you even read the first post of the kernel thread?

Back to OP, I used to hold power until the backlight would turn off (about 15sec) but one day it just so happened that my kindle did not turn off completely even then. After that I have been holding it down for a straight 20sec.

No, and that's why it's a surprise to them. Hashcode has been saying, repeatedly, he doesn't recommend it as a daily kernel. In big red letters, at the top of two threads, it says wall charging doesn't work. Throughout those threads it has other people posting who say they don't know why their kindle died overnight.
It's just a neverending...I wanna call it a cycle, but there's no cycle to it. It's more like a neverending stream of people who refuse to read.
Guaranteed, if I made a thread offering a kernel and in big red letters at the top it said "THIS KERNEL WILL BRICK YOUR KINDLE" and then proceeded to post a changelog and other information about how to install, etc... There would be no less than 100 posts the following day asking why their kindle doesn't work.
If the devs were offered a dime every time somebody failed to follow directions...

This is a discussion forum right? We are discussing.
If I can help even 1 person avoid that problem then I will. Maybe you guys should stick to the dev threads with all the smart people. This thread is for dummies who can't read.
Not going to argue with you on that one.

You do see the irony in all that, right?
@ryanhuong - just wanted you to confirm once that the wall charger is not indeed working for you.
I too had the same impression for some time as it _looks_ that way, but then realized it is working when I hit the top-left Refresh button in Settings -> Battery. The % kept going up.

With the newest kernel yes it seems to charge fine. The Pure AOKP build seemed to have more issues. Now I am using the newer AOKP and not does the charger work again, but the LED now shows orange or green (but the battery icon s still wrong).
Huge improvements so far.
This happened a few times with my Optimus V. This was because there was no offline charging support for AOSP ROMs at the time. The only way I could get the phone to stay on was to force the battery into a LG Rumor Touch and recharge it with that until the battery could boot the Optimus. Thinking how the Kindle Fire has no offline charging support and a non-removable battery strikes fear into my soul.
I know the AOKP ROMs fully power off the device. So at least I'm okay with that.
Also, is it bad that my Kindle Fire charges extremely slow with any other cable than the stock charger?

It will always work best with the stock charger, but until the bugs are fixed, who knows.

It does charge offline, the problem lies in the LED not reporting this properly (it doesn't turn on to reflect the charge status).

This is normal, as they usually provide less amps than the stock charger (1.8).
For what it's worth, I am on #33 AOKP KF Edition and the LED works perfectly. It's the icons that don't work right.
EDIT: I take that back. If the KF is asleep and you plug it in the LED stays dark. If the tablet is awake and you connect the charger, the orange comes on, putting the tablet to sleep the LED stays orange till it turns green when full.

Actually as one of the guys that's working on the kernel I would have to say you're incorrect. Wall charging does in fact work. The issue with the led is that the kernel doesn't correctly update it, as well as it doesn't update the from in a manner for the icon to change. If you download a battery widget in the market you will see that it does in fact charge with a wall charger. This is also a better route to go since the OEM charger puts out about 1000mv as opposed to 100mv w/USB 1.0 or 500mv w/USB 2.0. Only other steady charging scenario would be USB 3.0 because its output is 900mv.

So I just beat DeadSpace (yay), then I decided to reply on a harder difficulty. Within 15 minutes the phone turned itself off and the LED flashed RED once really briefly. Now it won't power on at all. The issue just happened, I don't know what's up.
I hope it isn't in the untouchable state (soft-bricked) again...................... Of course this stuff happens to me at this time in the night when nobody is awake to respone ......... What do I do? How can I fix it?
If it fixes itself I'll let you know.... I know for sure that I'm not playing Deadspace again after this...
EDIT 1* Just unplugged the charger and popped it into another wall. Now the Red Flash is just staying on, the phone is plugged in. What's going on?.......
EDIT 2* The Red LED stopped, phone still won't power on
EDIT 3* The phone now shows the low battery screen while being powered off... I'm guessing it'll power on now
EDIT 4* The phone successfully powered on, nothing is wrong with it now
Sorry for posting this thread it seems like a waste now..
Soooo! To make it not so pointless, I think I found out why it does this. I think Deadspace drained more battery than the phone could charge so the phone died (battery drain) with no warning. And when it did die the phone was in a state of "what the heck - - - computing - - - enjoy this RED LED!!!!!!". I guess it just means "Super dead battery". So in case anybody else fears for their $500 investment, just give it 10-15 minutes before you panic, and let your phones actually charge
From what I can gather from the various threads about the "Red Led Of Death" is that if it's flashing - it's recoverable in some way, if it's just a solid glow you're SOL. I've spent the last 2 days trying to get my N4 to live again Would actually help if people where more specific about if it's flashing or not.
Just got off the phone to the Play Store and arranging for them to start the RMA process. I guess I'll find out in a couple of weeks what the problem is.
When I first rooted I had the light for 4 hours, got it in and out of the red LED state 3 times that night. It was a horrifying experience. I do not know how I fixed it. I was jamming buttons and eventually got into the boot loader mode, from there I flashed stock boot.img and the rest is history... I wish you luck!!!

When I leave the Nexus 4 on a flat surface with nothing around it, it will randomly turn the screen on, wait the 30 second timer, then turn back off.
I did just install 4.2.2, but I hadn't used it enough before to say if it only started since then.
I'm currently unrooted, though unlocked the bootloader when I first got it so I do plan to root soon, would flashing a custom kernel like franco kernel possibly fix this? Or would this be a problem in the rom or a third party app?
In BetterBatteryStats I saw 2 Kernel Wakelocks that seemed to have a high ammount of wakes.
(Screenshots Attached)
And here's the BetterBatteryStats Dump File: https://www.dropbox.com/s/dbc2vn3littc0fp/BetterBatteryStats-2013-02-21_054751350.txt
Any help would be highly appreciated, thanks.
Possibly a third party app.

Not sure, guess it's possible, but even if it is lose I wouldn't expect it to effect it once it starts unless it gets bumped.
Also, what is the temp of the battery when charging? Not sure if it's true but I've heard that if the battery is over 40c it won't charge properly.
If you want, here's a really nice widget with temp on it: https://play.google.com/store/apps/details?id=ccc71.bmw
I would just be careful with anything to void your warranty until you figure out whats causing the problem, as I've heard a lot of stories about bad batteries, and shorts in usb causing the red light bug (For lack of a better name).

Thanks for the link. I actually looked through the 'must have apps for the N4' thread under themes and apps, and Goku80 had posted a link to a battery meter that I just downloaded and installed moments ago. I have yet to see what the charge temp is, but I will report back tonight. Idle temp is around 25*c from what I've noticed just now.
The only thing I've noticed with temps so far is when I have my phone pulled in and I'm watching something on the phone. The phone gets really hot, and the system starts to lag badly. I would assume this is a fail-safe for the battery to not overheat by downclocking itself, but this is only a theory.
As for the red light bug, I saw my phone drop from 28% to 4% instantly out of nowhere yesterday, with no warnings. I immediately pulled the phone in, and watched the battery meter jump to 30%. According to the red light threads, I think it's a software issue with the phone shutting down completely when it thinks it's out of battery to prevent damage. Hopefully we'll never run into that issue ourselves.
