For some reason, every couple of days when I plug my phone in to charge the battery overnight I end up getting an alert (about 4 in the morning!) to change the battery because mine is dead, along with the back up battery, and then the phone shuts off within about a minute. Luckily I have another battery, which I then put in, and then put the dead battery in the "back up battery" slot in the cradle to charge, which it does. I don't know why this happens but it is very frustrating. I am afraid of this happening on a trip out of town where I won't have the ability to use my cradle, unless I bring it which is a big hassle. I don't know what to do.
This IS vexing. By the fact that it charges the extra battery - we know that the power transformer is connected. Since the device does not seem to be charging (possibly even discharging?) - it seems that either the connector on the charging base or the connector on the device itself are bad.
Have you used the power dongle connected to the power transformer to attempt to charge the device? This would tell you if it's the charging base or the device. If it charges outside of the base, it's the base - if not, it's the device.
Best of luck!
How are you charging the battery - from mains power or through the USB?
I had a situation where I was only using USB power to the cradle and although this worked most of the time, I noticed that if the battery was already low (<50%) then the battery seemed to discharge rather than charge.
So the trigger in your case may be the amount of charge left in the battery before you start re-charging it.
I think other people have reported similar discharging situations, so some other ideas might emerge from a search of other threads.

Last week I was traveling, and I ran the battery on my 8125 dry. I got the unit to boot twice, but only for a few seconds, then it blinked out again. It never got past the initial screen. No big deal, I thought, I just charge it at the next opportunity. But when I hooked up the charger, nothing happened. No charging light, and no charging (left unit on charger overnight, tried 3 different chargers). Took the unit to an AT&T store, but they don't sell batteries. Fortunately, the clerk used the same phone and took the battery out of his and put it in my 8125. The unit booted, and when he connected a charger, the charging light came on and charged the phone. I moved it directly to a car charger, and the phone has been fine since then.
Did HTC build in a catch-22 here? When the battery is totally empty, you can't boot the phone and it will not go into charge mode?
Is there perhaps a way around this, other than having a spare battery that has to be kept in a charged state?
If you read around this thread, there are LOTS of posts about this. Yes, the battery in the 8125 is goofy. It'll crap out at you if the power goes below (and I'm recalling from memory, so this may be wrong) 5% of full charge.
Don't drain your battery completely. I usually shut my phone off around 10-15% and only power it when absolutely necessary until it's been recharged. If you drain it dead, it typically won't charge unless you use your AC adapter charger, or in rare cases your car charger. USB doesn't provide enough juice to jump over the dead-battery hurdle. Apparently, in your case, that wasn't even enough.
The best things you can do for yourself is show the actual battery strength on your today screen somewhere (doesn't matter how, or with what). Use something that shows the actual battery strength in linear value, not logarithmic value. This will help keep you from accidentally draining it. Also, like you said, buy a spare battery. My usage isn't that high, I can usually go 2-3 days without charging, but if you're draining it daily, an extra battery is a near absolute requirement.
This is usual for these phones. When battery goes dry it's very hard to charge it. You can wake battery up with atx power supply or similar with 5volt output. Just connect wire from power supply +5 volt line(red wire) to battery + and second wire from power supply ground line(black wire) to battery -. Power on atx power. After 1-2 min your battery is alive and you can boot up your phone and charge a battery.
Simple questions to the long story I wrote below the line(didn't realize it was so long):
I have two batteries that get a red light when trying to charge and they will not charge. I'm using a travel charger that came with the phone (used, not sure if it is the original charger). Input is 110-220V 50-60Hz Output is 5.5V 500mA. Says model T-HT-8125-SH on it.
Based on my findings, the phone should charge with 1.0A so it makes me think this is not an original charger. Old posts stated if the battery was this empty you need an original charger since it is the only thing strong enough.
The second question regards a new battery (just bought - one of the two above) dropping from having about 50% to having 0%. This is described in the story below, but could switching batteries / putting in a dead battery anything like this cause the new battery to lose it's charge all of the sudden? Or could there be damage to the phone other than the battery causing this issue?
Anyone have experience with this? What specs on a charger am I looking for that match the original charger? I may find other mini USB chargers around and if I have one that matches I can try it. I just don't want to damage the phone.
------
I have a wizard I bought used a couple months ago. It worked fine until a water damage issue occurred. I let it dry out for a week and then it was back to working fine. The only thing I noticed afterwards was sometimes the battery would drop from about 75% to 25% really quickly when it did not used to.
Last weekend, it was charging overnight and in the morning it would not turn on at all. I tried taking the battery out and trying to charge it again without success. The orange light usually does not come on. I either get no light, or a red light. Sometimes the red light stays, sometimes it blinks, but usually it is red when I first plug it in for a couple seconds then goes away.
I read recently in the manual that red means it is in LDO charging mode, thus the battery is empty. I thought the battery was dead so I ordered a replacement. It arrived, I stuck it in, it worked.
Now the weird part - I let it charge some on the new battery (it was around 18% when I got it). Then I decided to test the old battery and make sure that was indeed the problem. The phone wouldn't turn on or charge. However, I put the new battery back in and there is no charge. I tried charging it and the light was orange as it should be. However, after a couple more battery switches (I found out about the red light / orange light from the manual at this point so I went to test that with the old), the new battery is acting like the old battery. Both get a red light and will not charge.
Any ideas?
No answers for you but -
My original HTC charger has the following stats:
HTC p/n 70h00051-01
Model ADP-5FH B
Input 100-240v~0.2A 50-60Hz
Output 5V 1A LPS
Thanks for the details. I suppose mine isn't an original charger as it only has half the power yours does (and is a different model). It is probably some generic third-party charger.
For anyone interested, I did manage to get the phone charging by jump starting the battery with a 9 volt battery (saw an old post about it). Just connect the positive terminal of 9V to positive end of battery, and negative end of 9V to negative on battery. I used the metal from the inside of twist ties to connect the two batteries. Hold for about 15 seconds, then see if it will charge. If not, take battery out of phone again and use the 9V for another 15 seconds..See if it will charge afterwards. It only took a couple tries before it had enough power to start charging with my charger. Just don't hold it too long as the 9V is nearly twice what you need.
Anyways - it's charging now and is at 80%. We will see if it works like it should afterwards. If so, then I will have two working batteries for the phone.
Note - this shouldn't be an issue with an original charger that is 1.0A. It seems the third party ones are less (500mA, or my car charger is 650mA). I imagine the original charger is strong enough to get it started even on a completely empty battery. If not, the 9V battery sure is.
Just an update - not sure what is going on. It finished charging and the light turned green. As soon as I unplugged the wall charger, it dropped down to 51%. Ok...so that was weird...maybe it wasn't really charged. So, I let it charge up to 100% again. Light turns green. Unplugged it, dropped immediately to 39%.
Anyone have any idea why it would lose a large amount of charge when I unplug the cable? I'm charging it for the third time now...I'm not sure what is going on.
This is all with one battery (the old one). I haven't done anything with the new battery yet to try and get it to charge, but this might explain how the new battery lost the charge it did have and became empty like the original battery - perhaps it lost it's charge when I unplugged it just as the old one is doing...in which case this seems like a phone problem...hopefully not though.
Hi i get this battery from my friend.its made for htc hd 2 but when i put the battery into my phone the phone keeps rebooting itself.i can see the energy logo at the beginning and the screen goes off and starting again.i was trying to recharge the battery in the dock station but seems not working
Any ideas?
Thanks
If the battery has been laying around for quite some time, it should now be completely empty, close to 0V, a state those batteries should never be allowed to reach. This can easily cause what you are describing.
The best thing to try in order to revive it is probably just charging it externally, either in some special commercial product intended to do just that, or using a lab power supply (set the voltage to 4.2V, set the current limiter to about 700mA connect the battery, when the voltage finally climbs back to those 4.2V, disconnect it).
Anyway, if doing what i've described isn't an option, try just keeping the phone connected to it's charger, with that battery in, for 15..20 minutes, it may eventually be able to charge it enough to get out of this state.
I left my phone charging overnight via the wall charger. Battery registered at 1% when I started the charge.
When I woke up this morning I had a large low battery icon on the screen and the phone won't turn on. I disconnected the charge, tried charging with another charger but everytime it shows the SAMSUNG logo, then the large low battery icon.
I tried removing the battery, cleaning the charger port terminals, swapped out different USB cords, everything but a hard reset.
No matter what I do the phone will not start up.
Has anyone experienced this before, or possibly no how to resolve it?

Happened to me several times (on both my focuses Rogers and AT&T), and I came to the conclusion it's a bug somewhere in the phone or the battery. I'm not sure exactly where the problem is (software, hardware) but I can tell you how I fixed it.
What happens is, the battery is almost depleted, it actually is 1%. The phone incorrectly reads that thinks it's charged fully and doesn't allow further charging the battery. So, you're not able to charge the battery correctly.
Now, as I previously stated in some other posts, I recommend having a standalone charger (Samsung i9000 ones are compatible are very cheap) as well as a secondary battery. The depleted battery gets charged fine in the standalone charger and when it passes 5% charge, it can be charged fine (again) in the phone.
This doesn't happen often, I believe it happened 5 times in more than 300 charging cycles (2 phones x 150 charges, I have them for over a year) so it's not that common.
I also found that it *may* work if you charge the battery in another phone.
As a general thumb rule, it's important not to leave the battery to completely discharge, and connect the charger/usb when it reaches about 40% (when you can, ofc). Please refer to my post here to see how you can preserve battery life.
I have a 11th Gen 32GB FIre HD10. I use the tablet daily. Yesterday, I noticed that it is not charging. The charge symbol (lightning bolt battery) is still seen but the charge just isn't going up. I charged it for hours and it is still at 64%. I tried switch power supply and USB-C cable. At one point, it went to 65% but stopped. If I use it without plugging in, the battery will go down. And it will not go back up again through charge. Tried reboot. Power cycle. No difference. I have Fire Toolbox installed so the firmware isn't auto updating (since November 2021).
I am at lost right now. Is there a way to fix it without factory reset?
May be a battery failure, a port pcb failure is the next most likely cause.
A factory reset will likely just waste your time.
If the battery capacity has been declining and especially if it decreased a lot in the last month or two, it's almost certainly a battery failure.
Any swelling is a failure, if so replace immediately.
The tablet can tell it is charging and battery indicator appears to indicate the activity (by decreasing). It just seems that the charging circuit is faulty. But then, I have not come across any similar behavior through search.

Do not charge with the screen on as it will skew the charge curve.
It may be the power controller circuit but more than likely it's either the cable, the charger, the battery or the port pcb if it has one.

Unfortunately, that is the only way that I can use the tablet now. I fear that once battery dropped too low (e.g. 5% or less), it will refuse to boot and I will not be able to use the tablet even if I have it plugged in because the battery % will not go up.

Back it up now if it isn't...
back it up and replace.
I can think of something to try.
I have one old HP TouchPad that I have to charge this way.
First off, make sure you have a known good USB-C cable. I had one that was not uni-directional, I would only work when inserted one way. I'd try connecting it to a PC with the cable and see if it is connected. It might even give you the warning that it is connected to a low power charger...
Scrounge up a couple of lower power charging bricks, say around 2w or less, and power OFF the tablet,
Connect up the tablet and see what happens.
On my one TouchPad I have to use a low power wall wart to get it to charge. It won't even charge on the wireless cradle.
It will also charge off a PC at times.
Good Luck!
My problem went away awhile after a period of not charging. But the charging problem returned. I think the battery is charging but for some reasons, it is not reflecting it in percentage. On the other hand, the percentage is falling while it is in use.
The thing about the Fire Tablet is that there appears to be no way to charge it with tablet powered off. As soon as it is plugged it, it will power on.
6 weeks passed. I still have the same issue. Basically, the battery indicator is incorrect.
My Fire HD10 is still being charged and appears to hold a charge even for long period of use. But often times, the battery percentage will stop well before 100%. The exact number where it stopped increasing changes from time to time. It could be 41% today and it could be 33% tomorrow.
I have tried using it til it shut off. I recall that I can charge it back to 100% but the issue will return.
I need to make a tough choice. I am still on pre-7.3.2.2 firmware with Fire Toolbox. If I send the tablet back for "repair", I will most likely get back a refurbished one running 7.3.2.2+. But I also want my battery issue resolved.

A sensor on the mobo may have failed.
Observe what the battery voltages are with the shown battery percentage.
If the voltages don't match the percentage then it may not be hardware...
On an Li the voltage between fully discharged and fully charge aren't that much, around 1 volt or so like on a Samsung 4.25 volt battery.
I had the same problem with my 2021 Fire 10 tablet. I eventually realized it was not charging while connected to 5GHz WIFI. If I turn WIFI off or connect using the 2.4GHz band, it starts charging again. The 5GHz connection had become unmetered for some reason. Deleting the connection and making a new one as metered solved the problem, temporarily. Not sure how it is getting changed to unmetered. Really annoying bug.
