Kindle Fire HD 7" (2012 version) power problems - 7" Kindle Fire HD Q&A, Help & Troubleshooting

We bought it used but in good condition from eBay. It was well-taken care of. We only charged it a few times in the past month since we got it. The first time, we got a low battery warning, left it plugged in all night, and the next morning it was at 100%.
(Note: we do *not* have the official charger from Amazon)
The next time the battery got so low that it shut off. We charged it all night again, but it wouldn't get past 50% or so, regardless of how long we leave it plugged in.
Would a different charger help or is it one of these infamous battery/charging problems that I'm reading about?
Edit: I found another charger that puts out 2 amps and it charges it, but slowly.

[Answered][Q] AHHHH! I used the wrong wall adapter now my Nook won't charge up!!!!!

I have a rooted Nook HD with cm11 using nightlies (I forget which one. I think it's 2/1/2014). So, I lost my Nook HD wall adapter and started using a different one. This one had the exact same output specs, except it had .7A instead of 1A. Then it started to not acknowledge that it was plugged in and charging. I usually leave it plugged in overnight, so I found an old Nook HD adapter (I had replaced it a few times) with loose hinges on the two prongs. It was at 95% at night, then at 12% the next morning. Later, I was out somewhere and it said the battery was at 1%. I didn't really think much of this because the green (100% charged) charger light was on whenever I plugged it in, and it has said it was at 1% before, and when I plugged it in it usually fixed it and it would display the correct battery percentage. Well, this time it didn't. I guess I had forgot about the incident the last night. I assumed it was at 100% and it would just run down normally until it died even though is said 1%, but then it died quickly. I plugged it in where I was, but I had to go so all I saw a green light on the charging light, but then I had to unplug it. When I plugged it in later at the house it showed green, orange, then turned off. I left it overnight, and plugged it in this morning and it still did the same thing. I left it that way. I just tried plugging it into the computer because I've heard that some devices use different hardware to charge via just USB, but no luck. I plugged it back into the wall. What should I do?
P.S. Before root, and when I first got it (used), I tried charging it when it was off, and it didn't charge. I never tried again. Is this normal, and could it have somehow contributed to the issue?
OK, I know that it had said I posted the above at 4:00pm. I didn't. Can someone please respond?

Not sure what to think about this and guess no one else as well.
I assume with providing less power the electronics can compensate. Obviously, brown outs (for instance) are bad over a period of time but not as quickly as this.
More power is probably much worse.
Just don't think the charger broke the device. If you find the bn wall plug and it still didn't charge then it physically broke probably coincidence or not.
Addition: Assuming you use a smart phone why not use that wall plug? That's all I use. The bn plug is in the box.
Got a new cord and it works! It was on sale for 50% off as well. Guess I broke the cord by usinng the wrong adapter. Anyway the specs are actually something like 5.1V 2A, and the one I used was 5V .7A. Ouch. Thanks anyways!

[Q] Used wrong charger, battery jumped to 100%

I wanted to quickly transfer something from my laptop to my new Droid Turbo, so I quickly grabbed a USB cable thinking it was my Droid Turbo's cable. I had accidentally grabbed my 2012 Asus Nexus 7 cable instead. I plugged it into a USB 3.0 port on my laptop and after transferring some things for two minutes I noticed my battery was at 100%. I thought this was strange as my battery had only a few minutes ago been 87%. That's when I realized I was using the Asus cable.
Should I be concerned? I usually almost religiously never mix chargers.
Edit: I have just discovered that the cable is damaged and partially pulling out from the USB end.. could this have anything to do with it?
I had the same issue, connected my phone to a USB 3.0 port to backup some date and was shocked at how fast it supposedly charged up to 100%. I used a 3 y/o cable from an old Galaxy S3.
USB 3.0 has nearly double the power output of USB 2.0. So that could have something to do with it. Using a different cable or slightly torn one won't make a difference. The battery percentages also aren't the most accurate all the time. Your battery should be fine.

A USB 3 cable going to a standard USB 2 micro port? No voltage difference.

When using a standard USB cable the port does not matter.
I do think the calibration of the battery is off. I've had it go from 93 percent to fully charged on my qi charger just a minute ago, and yesterday twice, once on the turbo charger and an usb port on my laptop. I fully drained the battery the first day, Friday, and I think either it's still learning or the calibration is off. It seems to show it draining quickly the first sixty percent, then really slow down the last forty. Now I don't like letting the battery drain too low, decreases the battery life and capacity, hopefully it learns or next update clears this up.
This also happened to me on a usb3 port, but with the original cable. I jumped from 88% to 100% in about 5 seconds. This can't be right. Has to be a bug.
I don't think this is related to faulty chargers/cables. I had the same thing happen to me yesterday using my car charger for the first time (that I've used on 10+ other devices without issue) and the phone shot up to 100% in a few minutes. Ever since I used that charger all my other chargers that were previously working fine (turbo, qi, etc.), are charging the phone too quickly as well. I hope someone can figure out a fix for this, or an update comes out soon. I just wiped my device and set it up again, I'll report back if it's fixed.
I had this issue, I killed the battery thinking it would fix the issue when It charged, It did not. I factory reset and that also did not fix the problem. phone would show as 100% charged even when really only 3% charged. I ended up getting a replacement from VZW store.
Update - replacement phone from VZW is doing the same thing, only charger that I have used is a TYLT qi compliant wireless charger. (shows 100% for 6hrs)
Also are you guys on system version 21.21.12 or did you take the update?
Same issue here. Started today. Had since release. Exclusively use Tylt Vu charger. Have latest update. On Dalvik.

Mostly same here. Used the Tylt Vu exclusively, then used the Turbo charger once or twice. Phone was stuck at 100% for twelve hours yesterday, dropped to 93% after reboot. It appears confused as to what it should really be at. Seems that the Tylt Vu is the common thread here.
Fixed mine! after holding the power button for about 20 seconds the phone will shut off, I then charged the phone with the Turbo charger overnight which reclibrated the battery meter. This has not happened again since doing this.
Hope this helps!

This also solved the problem for me, thank you!! (I had also plugged into a usb3.0 port before this issue occured, hope they address this with a patch or some kind of fix).
I'm also having strange battery problems the past few days. The other day, randomly around 4pm I happened to notice my battery said 97%...just not possible since it had been off charger since 6am.. Yesterday, battery showed 35% and then died 2 mins later, powered off. Tried the power button for 20 and charged overnight, but on my qi charger I woke up to it only partially charged and not charging anymore. took off and put back on charging pad and it charged some more until morning. It seems the battery isn't calibrated and not showing the correct readings...anybody else? (oh, and it's a samsung charging pad)

unplug it from everything, hold power button till it shuts off, it will then show an accurate % reading. Plug into the turbo charger that came with it and walk away for an hour. Should re-calibrate and get you back to normal (assuming the issue you're having is the same as ours). this worked for me. good luck!

Sorry, needs to be plugged into turbo charger, I told you out of order, my bad.
plug into turbo charger, hold power till it cycles on it's own (you'll see the real %), leave plugged in and walk away for an hour.
Solved all of my problems, good luck!
(seems like this is caused by plugging into usb3.0 ports, and possibly some qi chargers. I use an lg qi charger overnight and have not had the issue. It happened to me when I plugged it into a usb3.0 port on a laptop).
great! this worked for me! thanks!
Well for me I've had this bug since day 1 and none of the fixes are permanent -- there's a bug in the software on Moto's side that needs to be dealt with. I posted a thread on Moto's support forum in hopes of raising the profile of this issue cause it's a showstopper for people like me who rely 100% on Qi.

Hi all,
I've had this same issue and I'm not sure when this happened, but I certainly noticed it immediately after using Qi charger for the first time.
Can we confirm if anyone on this thread had this issue by using a wired charging device, or whether this issue is synonymous with Qi charging?

Q: Battery Stats Problem / Percentage Jumps Erratically

Have been loving my Turbo, but yesterday my battery went haywire.
Took my phone off my TYLT Qi charger in the morning, and after 3 hours the phone still listed the battery at 100%. That's with about 40 minutes of screen time.
Turned the phone off and charged it until it was back to 100. After that, the rest of the day was without issue.
Went to bed, put Turbo back on Qi charger, used it in the morning for about 15 minutes and battery was at 77%. Put back on charger, went to 100% in minutes, took it off and within 30 minutes I was back in the 70`s.
Without root I can't calibrate the battery so I'm open to suggestions. Used the same Qi charger on my Droid Maxx without issue.
Scratching my head...
I had some erratic percentage activity just this morning. I also use a TYLT Qi charger. It sat on the charger all night, but when I pulled it off this morning it said 93%. I put it back on the charger and it started jumping back and forth between 93% and 100%. It kept switching between charging and not charging as it was sitting there. I don't think the TYLT charger is to blame, because it always functioned perfectly with my S4. There's definitely something screwy with Qi charging and the turbo.
This started happening to me yesterday. I think the issue started while connected to my car charger. I've used Qi charging most nights and the Turbo charger a few times without issue. My battery died while I was out, I plugged it into my car and the % jumped from 0-20% in about 30 seconds, it then continued to show it charging to 100% after a few minutes. Needless to say, the phone died about 10 minutes later (as it was incorrectly reporting a charge), and ever since then I've been trying to fix this issue. It appears all of my chargers are now charging the phone "too fast", which in turn doesn't let it fully charge and it dies quickly. It's improved so far today, and I've gone so far as to reset my phone to see if the issue persists. I'll report back with my findings.
My issue seems to be more in line with another thread, it might help you out as well: http://forum.xda-developers.com/droid-turbo/help/wrong-charger-battery-jumped-to-100-t2926010
Contacted Moto for support. After being told I need to manage my battery use and screen brightness (which I think we're all capable of doing) the last resort given was to do a factory reset. I tried to clear the cache in recovery but the phone shut down with a dead battery, I plugged it in, and supposedly it charged to 100% in less than 5 minutes! And that's without the Turbo Charger (heavy sarcasm).
I'll try the reset later, if that doesn't work I'm sending it back. Seems to be a common issue that others are having...
I've been experiencing the erratic readings as well. First, yesterday it stayed at 100% for ~4 hours. Then, after soft reset, dropped to 95% for a few hours. Another soft reset AND wiping cache, went to 89% and appeared to drain "properly". However, when it hit ~15%, it died; I hadn't charged it since the first stuck 100% reading. Immediately upon plugging it into the Turbo charger, it read 100% with current draw/supply at 0mA. I was running ART runtime, so I just switched back to Dalvick. It still reads 100%, but I'm seeing a current supply of >2.4A as if it were charging.
Backing up everything now, going to try a hard reset, and pray it takes. I'm not optimistic. This sucks not having root to figure out what's going on or at least being able to force battery calibration. I'll report back once I'm done...
Update: I reset the phone through recovery, am on Dalvik, and everything appears to be functioning properly. Phone has been charging and discharging as expected. I just tried an app called Advanced Battery Calibrator in an attempt to reset the battery file, so we'll see how that goes.

Same problem here. I use a Tylt exclusively to charge phone and tonight my phone died when it showed 100% charge. Turbo charged it for 10 seconds and then it showed 100%. Turned it back on and it died again a few minutes later. Never did this before and I've had the phone since it was released.
same problem here. and yes, I too use TYLT qi charger (seems to be common among the others experiencing this issue) and occasionally the turbo charger..
edit, will try this and report: http://forum.xda-developers.com/showpost.php?p=56862617&postcount=11
Following up, that tip above did seem to correct my battery back to normal (thus far). I drained the battery and then left it on the turbo charger for a few extra hours before turning the phone back on. I did this procedure twice. I have not yet resumed using the tylt qi charger, but ill report back once i know for sure my battery stats are correct, and then try resuming to use my tylt chargers (which are my normal daily chargers at home and the office).

this also solved the problem for me, thank you!!
I use the Tylt charger for overnight charging and had a similar problem yesterday. I noticed that the battery seemed to be discharging at the rate of 10-12% per hour with very light use. By the 7 hour mark off of the charger I was at 2% and the phone shut down a few minutes later. I plugged it in to the turbo charger and I was back to 100% in about 3 minutes. Obviously, the phone died a few minutes later once again. I was planning a trip to the Verizon store to exchange what I thought was a faulty phone, when I found the solution that seemed to work for other people.
1. Plug in turbo charger
2. Press and hold the power key until the phone restarts and shows the correct battery percentage
3. Leave phone on turbo charger and allow it to charge normally
4. Stop using Qi until there's a fix (if they even know about it)
I hope someone's looking into this as I really like my Tylt. I used it for a year with my Maxx with no issues whatsoever.

From what I've read, the wireless chargers may not be the main issue, have you plugged the phone into a usb3.0 port recently? that seems to be the beginnings of troubles for people. I use a qi charger every night and don't have this problem unless I plug into a laptop for some reason.
Glad you're fixed!
Well I thought the Qi charger was the issue so I cleared the cache and Turbo charged all night... So this afternoon I was at 70% when I took a picture and soil of a sudden... Dead.
So there goes that theory!!! My XT1254 was fine for months. This all started last weekend. No new apps. No explainable reason. Just that Moto is fail.
This is ridiculous. Why is there no fix? Ready to sell this pos and say goodbye to Failorola.

Moto X won't charge past 3%

I have a Moto X 2013 that, after replacing the battery with a supposedly new, OEM battery, refuses to charge past 3%. This phone is rooted and was rom'd with the Nougat xPerience rom, but I tried flashing it with Nougat Lineage as a troubleshooting test.
I replaced the battery last night without incident, and the phone booted and seemed to behave fine, and the battery had about 30% charge. The only issue I found immediately after replacing the battery was a battery app installed on the phone saying the battery hasn't been charged for -19000 hours, or something a long those lines (I can't remember exactly what it said, as I did not install the app, my friend did who I was fixing the phone for. I just remember it was some outrageously large negative number.). Thought it was weird, and maybe thought it was a software issue, so I booted to TWRP and wiped the cache and dalvik. Rebooted the phone, and the app reset to something along the lines of 500 hours. That is a bit more believable.
I plugged the phone into my laptop to let it charge (as it was the only way I could charge it at the time), my laptop saw the Moto, and the Moto said "Charging..." and "Android Debugging...", and thought it was working. I had to run an errand, and when I returned about an hour later, the phone hadn't moved a drop up or down. My laptop was asleep, so I assumed maybe it just stopped charging when my laptop shut off, and I was exhausted myself so I just let it sit on standby all night.
Morning came, and the Moto is dead. I plug it into the wall charger I was just using to charge my v10 with (brand new cord, made for data transferring and charging that I used once before with the old battery), and head to class, hoping it'll charge. Guess what? It didn't charge. Well, it did a little. It went up from 0% to 3%, and sat there. Annoyed, I unplugged and replugged in the phone. It came up with the white battery charging screen, switched to the Nougat "N", vibrated, then went to a black battery charging thing. Once there, the battery icon went up two squares, the screen flashed, and the phone died and stopped charging, then repeated itself a few more times until it went silent.
I started to think maybe my brand new cord was screwing up, so I grabbed another one I had and plugged it into my desktop. I had read on another thread that sometimes you can force the phone to jumpstart charging by plugging in the phone and holding down power + volume down for upwards of two minutes. I tried this, and it charged enough that I could turn the phone on again, but it wouldn't charge enough to do much more. I left it plugged into my desktop for a few hours, not allowing the desktop to fall asleep, and yet the phone was still not rising above 3 or 4% despite the fact that it says that it is charging. Oh, and the phone was on the whole time if it was plugged in, but the moment I unplugged it (Like the one time it got over 5%), it immediately shuts down.
I know I'll probably just have to buy another new battery for the dumb thing, but I am just curious to see if there is anything I can do to fix this, just because I cannot currently afford to buy another new battery (and my friend, who this phone belongs to, is getting impatient on getting it back.)
Thanks for any help!
I have the same problem, charging topping out at 3% with a "new" battery.
Did you change the battery? Did it work?
Thanks for your feedback.
(FYI, this phone is running the stock lollipop firmware.)

HTC One M7 Resurrected, but Wants to Die Again

Hi.
I've had an HTC One M7 sitting around for years. I gave it to my mom after I bought a Nexus 6P, having used the One for three years. She got another few years out of it, but then the charging port started giving her trouble. The phone wouldn't always charge, and she got frustrated with it, so she put it in a drawer and let it die for good. I retrieved it from her, but not before it was kaput.
Today, I installed a replacement battery that I'd ordered and managed to bring the thing back to life. At first, it wouldn't take a charge at all, but I wound up getting it going by plugging in my Nexus 6P charger with my Pixel 2 XL USB-C to USB 2.0 adapter and running a USB 2.0 to mini-USB cable from that to the phone.
When I turned on the phone after letting it charge for a while, it had 55% battery, but I noticed that it was getting stupid hot.
So, I shut it down and kept charging it, this time having switched to a 5V 1.5 mA charger instead of the 3 mA Nexus charger. After it had cooled down, I booted it back up again and the battery gauge read 5%. ???
Any idea what the problem is? The charger shouldn't be an issue, right ... because it's not quick charging since it's not plugged into a smart USB-C cable (at least as far as I can figure). I suppose the battery could be junk; it's older than the one that had been in my phone (the date stamped on it is a month prior to the date on the original). I'm at a loss, though.
I'd appreciate any ideas.
UPDATE:
When I booted into recovery (the phone is unlocked, rooted, and s-off), TWRP told me that my battery was 45%, whereas the OS was reporting 5%.
I booted back into the OS (5.0.2) and it showed 20%. With the charger connected, it soon dropped to 17%.
I booted again into recovery, which now showed me 8%. I again plugged in the charger and it showed the (+) to indicate charging, but the percentage then dropped to 7%. It never climbed.
I turned it back off, let it charge for a while, then booted back into the OS. It showed 12%. I decided to shut it down and unplug it, as it was late. This morning, I plugged it back in and left it for a while. Upon booting it up ... battery was still at 12%.
So, I did what this guide (https://forums.androidcentral.com/v...ry-charger-reset-procedure-htc-one-m7-m8.html) recommends. The phone is now on and charging and, at last check, it was up to 27%.
There are plenty of variables, here: the phone is old; it's been defunct for years before I revived it yesterday; the replacement battery was from the month prior to the stock battery (perhaps irrelevant); the charging port is sloppy and the cable needs to be "just so" to work; the OS is a de-bloated factory AT&T image that I used to de-brick the phone after I'd wiped the original OS before I had the opportunity to make a Nandroid backup (ergo: I wonder if Sense is (part of) the problem).
If anyone wants to take a stroll down memory lane with this phone and spitball with me, please feel free.
