disclaimer: Please delete this post if there is something like this here or somewhere else in Kindle Fire General already (and feel free to move this or re-post it somewhere else)- I have looked but haven't found anything like this yet so...
I have seen a few posts about the charging issues and feel like doing something productive here in the 'General' (non-dev) section of the Kindle Fire that may hopefully help many people using Hashcode's awesome kernel. I am running the new AOSP jelly bean rom by hashcode (using the same 3.0 kernel used by many) and have figured out the behavior almost completely in regards to charging on my device so I am going to post what I have observed in the hopes to help out others and maybe sway those 'on the fence' that aren't wanting to unlock the full potential of their device because of this 'issue'.
I recommend always using the wall charger that came with your KF. Some of the threads where people are having actual charging issues they are attempting to charge through usb. I once owned a Dell Streak 7 where usb charging was disabled (charging light would come on but it would not charge) by Dell since there wasn't enough current to adequately charge the device. So ALWAYS (whenever possible) use the included charger!
I have never yet had any issue getting my KF to charge when plugging it in when it was TURNED OFF. Plugging it in immediately turns the device on and once it starts booting up the led indicator turns from green to orange and is confirmed to be charging when accessing settings->battery.
Twice since I have flashed the JB rom I have plugged in the charger while it was on (and waited about 30 seconds) and on my KF in the settings-> battery still showed "discharging". So here's my methods when observing various charging situations (and it's really simple) of ensuring the charger will work properly.
My device's charging indicator appears to work properly but is only on when the display is on (orange when charging, green when battery level is 95-99%, off when fully charged).
An oddity I have noticed (and also read somewhere else) is that the charging indicator orange led light has a tendency to turn on (and stay on) and confirm charging much more often when the display is on so I always have the screen on when plugging it in. It's still possible to start charging with the screen off and everyone's device will behave differently. I am not trying to discourage anyone from charging with the screen off. Again this is what I have noticed in regards to my device.
Make sure that the display is on when you plug in and if the led comes on then you're good. If not, sometimes it is delayed so wait 5 seconds or so. Sometimes you need to cycle the screen on and off once or twice and the led will come on. Always confirm in settings -> battery.
If you ever plug it in and have the led come on and it immediately turns off (this is the behavior where I have experienced issues) check in the settings-> battery and if it says 'discharging' wait 5-10 seconds. Hit the refresh button. Try cycling the screen on and off once or twice. If it still shows 'discharging' then unplug the charger. Start over from the beginning (this has happened to me twice).
That's about it. So if you are on the fence and aren't sure if you should flash any ICS/JB rom only due to concerns regarding charging... please do yourself a favor and take the plunge-the performance is incredible. Hashcode and other devs here have poured out their time and efforts to make our Kindle Fires AMAZING. If you like their work and efforts hit the 'thanks':good: button. If you LOVE your dev's rom and can't imagine living without it hit the 'donate' button so you won't have to worry about living without it.:highfive:
If anyone else has any additional observations please add them to this thread- it will be very helpful for others!
Great post, thanks OP. I had the same exact problems with charging. That said, the problem seems to have gone away now that I just flashed the [CM10] Jelly Bean ROM that @twa_priv posted. With this one, Google Now works (albeit without voice search), and I'm seeing the amber indicator even when the screen's turned off.
Fantastic work by @twa_priv, and many thanks to @Hashcode!
Edit: Scratch my last. Back to keeping the screen on. It was going well for a while until the amber light decided to go off. Ah well, guess we'll have to wait a bit longer!
Great post! Mine charges regardless of both the state of the LED indicator and battery status under settings. I plug mine in every night, the LED blinks orange, goes off with the screen, and the device is charged at 100% the following morning every time. It also charges even if the status is listed as discharging, and on mine it will be listed as discharging the entire time it is plugged in. It should also be noted that mine charges just fine, albeit rather slowly, via USB.
may i just add that if you have a battery monitor widget, like Battery Life, from the play store, most have a little charge icon that shows up when the device is charging, this has worked for me ever since hash first made his kernel and it was all buggy.
hope this helps someone.

Same for me.
After I installed jelly bean, I started having charging issues. I would leave the kindle charging on the stock charger all night and it wasn't even at ninety percent. I then noticed that I could not connect the kindle top my computer, PC or Mac, not adb not usb mount, nothing. I even loaded Ubuntu on a stick and it was not recognized. I thought maybe it was a kernel problem so I went back to Modaco and I still had all the same problems.
Coincidentally, the same day I had left the kindle in my car. Maybe the heat fried something. Just in case I thought I would post in case this happened to someone else. I don't think a kernel could fry hardware across roms.

My two cents:
I'm running Jandycane 1.4 (by lithium), and I'm using a charger that came with an old Moto Droid. There is no LED indicator showing anything, nor does the tablet itself have a charging symbol showing in the task bar (no lightning bolt, doesn't say "charging" or anything).
Regardless of everything, the device simply charges when it's plugged in. Every morning, I wake up to a charged KF, ready to go

On a few occasions now I have plugged it in to charge overnight, to find that it has not charged, or only part charged. The LED starts blinking as it should, but the next morning it is still blinking and only gone up, say 10%.
Also on occasion, I plug it in to charge and although the LED blinks, the battery icon does not change to reflect that it is now charging.
Has anyone else had similar problems or, as I suspect, do I have a defective unit?
I have only charged and walked away from my device once (that I can remember) and for whatever reason it either failed to charge or was just charging stupidly slow. I ended up unplugging booting the device and plugging it back in again where it proceeded to charge normally.
Not sure if this is similar to what you describe but it is a strange behaviour while charging even if I have only come across it once so far.
Well, there's not much chance of getting a replacement any time soon, so I will just cross my fingers that it needs "running in". Will try rebooting also.
Thanks.
There are reports of this issue happening, indeed its just happened to me!
Youre not alone and afaik its not a defective device. If i find more info ill let you know

I can only charge mine effectively if I turn the Vega off, if not if charges for a while but then the light just goes out. If the Vega is off it charges fine.
There has been a lot of talk about the sub-standard chargers over at MoDaCo, I keep meaning to try and get a new regulated charger from somewhere and try that.
Maybe this weekend.

Well spotted, now I turn it off before plugging it in, it works fine.
Another annoyance is my screen brightness reverting to default after every boot. I have to go into settings and although the adjustment bar is at max, have to re-set it to max for it to apply. Anyone else?!
So the phone was really low, at 6% this morning. SO I put it on the wall charger. I saw the icon come up that it was charging and then put the phone down.
A while later I went back to the phone and saw that although the charger was plugged in to the wall and also plugged into the phone, it was NOT charging.
Using the phone I went to my contacts to check a phone number and then it turned off, due to no charge.
I plug it into the wall charger, the USB connected to the computer, as well as the car charger and here is what happens:
The top and bottom of the phone blink red for about 1-3 minutes.
Without pressing anything on the phone it automatically turns itself on, I see the Sony Ericsson boot screen, the Windows boot screen then my SPB Mobil Shell screen for about a second and then it turns off again showing and the blinking red light for about 1-3 minutes and then it starts the process all over again.
I think that a setting for Backlight/Power management was changed. As setting similar to "Only charge with usb", or "only charge when connected with ActiveSync" or somthing like that.
The problem is that I turned off the Active sync on the phone in order to conserve battery power so that I could look up the phone number from my contacts. And after I did that the phone shut off and I cannot change it, because it will not charge.
I do not have a different, charged, battery to try and do not think that I can find one easily.
Any suggestions?
Now when I see that the phone is re-booting(I see the SE logo), I use the stylus to to soft reset. It is obvious that there is some type of charge happening before it re-boots, , otherwise it would not re-boot. SO my theory is that by doing a soft rest between restarts, the battery will gain more of a charge each time. And possibly have enough of a charge so that I can go into my settings and see the backlight/ power settings have been changed.
So I took a battery from my old SE 902 phone and rigged it to work with my X2.
It booted up just fine. I was able to get into the menu for power settings. Nothig was changed however I did check the box "do not charge when connected to the computer" backed out of that screen and then went back into the screen and unchecked the box.
I powered down the phone and the screen went to the default charging battery meter.
I then put the proper battery in the phone and it was still blinking red. I saw it blink green for a few seconds, then I felt it vibrate, and then I saw the green battery meter. But after a few seconds it went back to blinking red and I could not see the battery meter again.
This seems to be happening intermittenly. As of right now there is a green blinking light and I see a dimmed battery meter.
Hopefully it will be fine, we shall see.
So it was charging for a while and now has stopped. I see the battery meeter, but there is no green bar moving up. and the light has stopped blinking.
I unplugged the usb and I still see the battery meter with no green bar moving. Installed the back cover and plugged the usb back in.
Now it is back to the red blinking again. . . ? ? ? ? ?
I think that it is a battery issue.
CAn anyone suggest why a battery would all of a sudden stop working?
Just ordered a new battery. $70.00!!! Ouch!!!
It does come with a battery charger for use with a Mini USB, but still, $70.00 is a lot of money!!
I will update with the results after i charge it up.
I got the new battery and put it into the charger. As I mentioned in an earlier post the new battery came with a separate charger for use with a mini usb. At first I had problems. The charger would not charge the new battery. I was using a wall connected mini usb to power the charger. So I went to the computer and tried the mini usb from there. It still would not charge. So I took the battery out of the charger and put it into then phone and went back to the wall charger and it was charging. I could feel the phone vibrate and then saw the battery meter slowly fill with green and back to empty and then fill green again.
So I decided to do a few other chores around the house and went to check the charging status after about 10 minutes. I noticed that the phone was on!! I did not turn the phone on. No one else was in the house to turn it on. It was just on. Weird.
So I took the battery out of the phone and decided to try the new charger again with the computer mini USB. It WAS charging this time!! I charged the new battery on this charger using the computer mini USB until the red light(charging) turned green (finished charging) and then put it in the phone. It works fine.
I then decided to put the defective battery into this charger and it was actually charging!! I left it overnight and it was green this morning: identifying it as a full charge.
When the new battery is down to 10% or less I will take it out and put the defective battery in and see what happens.
So I put the original battery back in after the green light came on identifying a full charge on the accessory charger.
It showed 1% and a message came up identifying that "the battery is low, please charge asap", something like that.
So, in my unprofessional opinion , the original battery is toast.
The new battery worked great after its initial charge using the included accessory charger.
When I decided to charge it using the phone itself with the wall charger I noticed some really weird things happening.
First of all you should know that I downloaded and installed Spoon Charge. Look it up here on the forums, free and works great. It basically tells you what charge level you have, temperature of the battery, what voltage is coming in to charge it and also type of charge the battery is doing: trickle, fast, very fast and on battery.You can set it to read reading at specific time intervals: I have it set to read at every second.
I noticed that the charge kept bouncing between very fast and trickle. At one point it went to on battery, then to trickle then to on battery then to fast.
Ok. Weird. . . I thought to myself.
So I let it continue to charge overnight.
The next day I "tried" to use the phone. it was as slow as it was at it's factory installed settings before I did the memory card fix, accelerator settings, and other fixes that I forgot now have forgotten that I have installed.
At this point I decided to drain the battery as fast as I could by turning on WiFi, Bluetooth, and play a movie at the loudest volume possible. As soon as it reached 10% I took the battery out and charged it with the accessory charger. The next morning I saw that the indicator light was green showing full charge and installed the battery in the phone. It booted up and I immediately received a message that the battery was low, saw 1%.
Knowing that this was a BRAND NEW BATTERY, I turned off the phone and took the battery out and waited a few seconds until I put it back in and rebooted the phone.
This time it said 86% charge!!!!!!
WTF!!!!
So I tried to use the phone and it was as sluggish as before. After about 25 minutes it was starting to be a bit faster but nothing like it was before.
I am really confused now. Since I have a new battery I have ruled out that as a problem. So now is it the phone itself? Could it be the wall charger that is faulty?
Any other suggestions would be greatly appreciated.
Another update.
I put the original battery in the phone and now it works!!!! The old battery that would not charge now charges and works!!!
The phone is not the same. Still really slow, can't get it out of the "LOCKED" position when I want to answer a phone call. Opera is sliggish then fast then sluggish. Not what I had the phone at before all of this started. It actually WAS stable. It WAS useable. Now I want to throw it into the drink!!!!!!
Not sure what to think anymore.
well bro go into the system help of ur mobile press as i say
2ce the end button one time call button, 2ce the end button one time call button,one time end button and u will find the problem it is in the charging port the same issue with me
Long time lurker, but first time poster. The issue started when I got the OTA Gingerbread update. For some reason, the update would not work, and I had to do the update manually. Every since then, my Tab does not charge correctly. No matter what charger I use, the battery icon always has the red x on it. It will charge, but takes a very long time, like I am charging via the USB port (which I am not). The other weird thing, is that no matter the battery charge level, on the lock screen, it says "please connect charger". I'm wondering if I can re-do the Gingerbread update and see if that will help. Any ideas?
Jive
I may not be of complete help, but it seems like a charging issue. I had a same message but that was because I charged via USB hooked to a computer. it continued to say to me to charge. So I rebooted and it was all fine. My tab is EU standard tab but I guess that either your charger is broken or your battery is completely confused about its status.
hope you find a better solution
Thanks for the reply. Right now I have it completely off the charger, and it's showing right @ 80% battery. But when you turn it off and back on, the lock screen tells you to connect the charger. Very odd.
Jive
did you read through the Battery stats clearing thread in this section? Might be able to help you out.
Also, check the accessories section, there are a couple threads about various cables/chargers that should help you with the red X issue. (i'm still waiting on one of the cables I ordered to find out if it does what it says, then I'll report back if it does.)
It appears dead. It's late at night so i've yet to try googling about recovery through a pc of some such, truth be told while i can flash a rom with instructions, i'm no guru or anything. It was running CM 10.2? the latest stable release for N10, think that's the one.
I was just browsing a forum, and after posting, the disply started to stutter as i scrolled up, when i stopped scrolling, the stuttering decreased, and then as i scrolled and scrolled fasster, the stuttering increased until display turned black (stoned curiosity...) and now i can't get anything out of my N10. Holding power, trying to reboot into recovery. Nothing. No lights, sounds, vibrations. None of the normal stuff.
anyone got any ideas for me to awke up to? I think that if i can't get any life out of it, then would it be a case of trying to sideload or such with ADB? as i say, i'm a complete rookie, just a couple of flashes under my belt.
Second question, i probably have the answer to, but am i right in thinking custom roms void the warranty?
edit: Plugged it into the wall a few minutes ago. It had had about 40% remaining, but when i plugged it in, i got the battery simbol on the screen (big white battery charging in center) and any time i press or hold the power button, or with volume buttons, i get nothing but the icon. I'll keep it plugged in for now and see what happens. But by the look of i assume if it can do that when plugged into the wall i sohuld hpoefully be able to connect via my computer in some manner
If by stuttering you mean blinking, this has happened to me when my N10 was on charger with a dead battery and it drew more power than what the charger could provide. When you scroll, the CPU frequency gets bumped up and the tablet consumes more power. After a while it just turned off for me (when I changed to an other app I think), when there just wasn't enough power.
So I would suggest leaving it on charge for a few hours, then try holding all buttons and see if you can get into bootloader. I've had the battery levels not display correctly on some custom ROMs, (for example I would do a reboot at 60% battery and after it reboots it only said 13%) so just charging it a bit might solve the problem.

Thanks. As of 5 minutes ago it got back to life. All battery apps showed 40 odd. Strange.
i think your battery has gone/ on its way out, exact same happened to mine, you need a pogo charger and the original wall adapter to provide enough power to switch it on. Only thing which worked for me, hope it works for you.

Might be the battery, might be glitchy software. Plugged it in via USB and it worked sometime later. Will be keeping an eye on it.
It will probably be fine. I thought I had a bricked N10 but turns out the battery was dead. It is fine now. THought I had a bricked N7 also, turned out the battery plug got loose, (screen would flash every 2 seconds with static on the screen) popped it open and oushed the plug in and that is fine now too.
If it continues to die around the 40-50% mark, you'll need to send it in for repairs. Make sure they don't just try replacing the USB port on it, the battery itself is the culprit.

Hi guys,
My Nexus 7 (2012) turned off(not properly) when the battery level was low and won't power on. I tried a battery from a working tablet and tested my battery in another tablet. It seems like the issue is somewhere else.
These are the things I tried:
- leave it for a couple of hours charging (no battery sign at all)
- hold the power button with/without the volume levels while it being both connected and disconnected.
- tested my battery in another tabled and put a fully charged battery from another tablet
- made sure that the battery is connected
There was one more thing I tried - to press the Power button with no battery inside but the tablet being connected to a laptop via the USB cable. One could hear something like a boot noise coming from the tablet (doesn't happen when the battery is inside)
In December, 2015 I installed a Custom ROM with android 5.1.1 which I found here http://forum.xda-developers.com/nexus-7/development/android-6-aosp-grouper-t3268172/ (the thread was renamed and is now about the Android 6 update) The tablet worked fine for these 3 months but one day when I was checking my email it went off and won't respond to any actions.
Could you please help me to fix it? I'm just not ready to give up on this tablet. Thanks!
Both you and i, same model, essentially, the same circumstances. I also tried every method you mentioned as well. Even down to the flashing of a rom. Same results. I even tried "jump starting" the battery. Not wanting to give up on it. It sits in my closet like that boy in A.I at the bottom of the ocean, waiting... I know that is not the reply or help you were looking for. Just so you know, you are not alone..

Well, that's a good start, at least I am not the only one!
Have you tried to connect your device via USB? My laptop can see a connected device but it can't recognize it and I hear some sounds coming from the tablet when I try to hold the `power` button. This made me think that it can be a display/screen related, so the device works but we can't see it due to the broken screen/display. Don't know how to check that though.
Same here, stock Nexus 7, won't turn on, just switched off one day and won't come back on, have tried everything as suggested above, can't get it to flicker, doesn't even register the power connection with a green light or anything

Try replacing the screen, just to check. If that doesn't fix it, at least you have a brand new screen!

let it sit on the charger for a hour, then hold down the button for 20 sec
same issue here as well ive had it for about a year and im not able to access anything via my pc google help forums had no answer either, looks like we may be screwed..........
Hi, I just had same issue with my tablet only thing is that I was using it with ~20% of battery, nothing special - browsing the web using chrome, then the screen lit gray and shut off. After that no response either from charger, holding power button for 60+ seconds didn't work either, tried re-connecting the battery, still with no signs.
And then, I tried to plug in the charger and then pressing VolumeDown+Power immediately after connecting the charger. Suddenly got some response, that battery charging icon appeared, and it shows my battery charging, but from 0%. Still waiting to charge a bit until I can try to boot it.
I'll update this post with any news.
EDIT: When I connected my tablet to the charger it had that hissing sound, but after few minutes it stopped.
After 15 minutes of charging I managed to boot my Nexus7 with 7% of charge in it a that moment, It seems to work for now.
Summarry of what I did to solve my problem:
1. Opened the back of the N7 (I used a guitar pick for this) and re-connect the battery.
2. Then plugged in the charger and at the same time pressed VolumeDown+Power, battery icon lit up but went out, repeated step 1, and then step 2 again gave me animated battery charging animation which showed up for like 10 seconds
3. Waited for 10-15 minutes and tried to boot normally. And it works now

Honestly, I do not think it is the battery, I can see the Charge signal, and the Battery is showing 1,784 VDC tested unplugged and disconnected, my smart young co-worker seems to think POST is failing, I still never see a "Charging" indication.
Does anyone know , Is there a fail safe, say the battery is disconnected, and usb charger is plugged in, will i just see all 5VDC at the sub port, ?
I never see a screen flicker, DEAD battery sign, nothing.
co-worker, tried some things that made sense when he explained what he did, I would have to agree with him.
Now it is rooted, 4.x something I forget, Never went to 5.x did once early and did not like it, Back stock, ran 2 days no issues, Rooted again, 4.x still do not remember, worked great 3-4 months, Sons ran it to DEaD and that was it, put it up for 90 days or so, wife got new tablet, kids have Fire each, and here i am tabletless, CRAP, did not want to throw to much $$$$ at this thing, nor did I want to buy a new one.
Samsung Tablet here we come.
any body want this Nexus 7, it is a 2012 model.
