Hello.
Yesterday I upgraded from KatKiss #018 to #019. Up to now #018 had worked perfectly, but today with #019 I noticed that when plugging in my charger (I don't have the dock), I didn't get the little 'flash' sign on the battery notification; going into the settings to look at battery usage, I noticed that i said 'Battery not charging' even though I had left the charger plugged in.
I unplugged the charger, turned off the tablet, and replugged the charger, and the tablet turned on, which it does when plugging in the charger and being off.
Has anybody had this problem? Is it really charging but not notifying it? If not, what can I do besides reflashing?
Thanks!
me too

I have the same issue, battery will not charge. and it seem that it will not get supported here, no answer from the dev, please dev look it up
I am fine with kitkat 19. You guys above may give a try to change a data cable to charge your tablet.

No problems for me and most people I guess otherwise they would stay away from the rom if it was not charging
Try to power off completely your tablet, then cold boot.
Try to change cable, try to test with another charger.
If that doesn't help do a full wipe and a clean install and test again before reinstalling anything else on your tablet.
if that still doesn't help, follow the procedure to report an issue in my signature, I'm not psychic.
Hello.
I have a problem related to the battery as well. Ever since I flashed to #19, my tablet and dock battery seem to run dry very quickly in sleep mode. I have come home from work to occasionally find the tablet unable to boot (it had a dock charge of no greater than 75% and a tablet charge of 100%) and when I plug the charger into the dock and then boot it, I find both batteries have next to no charge.
This is only on timduru's KK#19. I never saw this problem on #18 and below, or any of the previous 'droid versions (4.3.1_029 or 4.2.2_226).
I am currently letting the tablet's battery run to empty and then I will be charging the dock and tablet separately, but this is the first time I've ever encountered this problem.
okay

Did you try another ROM? I'm on #20 and I think I have (mentionable) more battery life. Not charging issues. Guess the fresh installment / wipe helped or an energy eater didn't survive the reinstall. Also I could observe two things (which I don't know of if they are related): Sometimes when the tab was docked it didn't charge. Second the the tab hat a battery problem. When docked and in sleep -> Dock empty next morning. I controlled this with Juice defender but weren't able to locate the problem in an app. This is now gone.
From my experience: I bought 2 power cable for the TF101 (only cable). One works as USB cable with no loading feature (not on USB 3.0 nor on the wallcharger). The other one works as USB connection cable and as wall charger. I can extend the original cable with USB to USB cable to transfer data and charge. I can't get any of that both two (CHEAP) cables to load extended or trasfer data. The two cables I bought at ebay were diffrent vendors. One for ~2,50€ the other for ~4€. If I remember right the original cable where much much more. What I want to say: There are huge diffrences in USB cables. Dunno. It would be a strange accident that the charger or cable broke when / while you intalled a ROM. Could it be that the "intelligent" battery stats are broken somehow? So they think the battery is full and therefor not charge? Or would the icon / indicator then show 100%? Does the icon get its information from the same source (or directly from) as the android battery management?
(ps: 12 hours for 35%=! ROFL!?? What charger is that?)

if it takes that much time even when it's off, it means that it's only charging at 5V.
Also at 5V it won't charge unless the screen is off if I remember well.
There's a special pin/connection made in the cable for the charger to detect that it's a Transformer plugged that will make it charge at 12+V
There's most likely a pin/ contact broken either in your cable / charger /tab, that prevents it to charge at high voltage.

So you say you go with option #3 then because u already did option 2, right? Quote Tim on option 2: "Try to change cable, try to test with another charger.".
So you have 2 x THIS and 2 x THIS? Because that would mean, what Tim suggested I guess. As far as I know this is the only way ASUS shipps the original TF101.
I'm asking because most people that I know would buy another noname charger or even just a noname cable instead of horribly expensive original pieces. If you really got the 2 x 2 pieces shown above,
then I'd guess wether your tablet is broken or the software on it is broken. But again: Did the charging problem REALLY firstly appeared when intalled the ROM? Or did you install the ROM because of the
fault? Or don't you exactly know.
To point out again: It would be a strange coincidence, that both cables AND adapters would stop working exacly at the same time when u installed #19. If you use 2 different cables at the same adapter: Then it's possible that the adapter is broken and only gives the USB (5V) loading speed. If you use 2 adapters and 2 cables and tryed all combinations: The most likely something with the tab isn't cool. The software or the hardware...

I have loaded #29, and I started seeing this issue immediately. It was fine before that. After loading the ROM, it would only charge when TF is dead. I have the original charger and cable that came with it which was working fine before the upgrade. So, I don't suspect either of them.

I was going with #29 and #30. Havent seen or heard about any loading issues but that was related to loading the tab on an USB port ... What actually is an bad idea even on USB3.0.

My nexus 5 started chargning very slowly lately, and it shows that it is charging through USB, altough it is connected to a wall charger.
I tried a different charger/different usb cable - same results.
What can I do?
Maybe it has something to do with the recent 4.4.4 update?
Thanks

well it keeps happening, and I have to plug to phone to a pc everytime for a sec and then back to the wall charger for it to charge in a decent speed....

yeah, I have same problem. my nexus 5 after 4.4.4 update charges veeeery slow. after 2 hours it charges maybe 20% even if the phone is switched off. can someone help? should I do downgrade to 4.4.3?
btw. Im using stock rom, kernel, recovery,etc. no mods at all. stock wall charger which came with my phone and tried other ones with no improvement.
thanks
I doubt it's a software issue, or a hardware issue with the battery. It's probably the cord and/or the charger going bad.
I tried several different chargers/cords(sony,nexus4,htc,samsung) and it was even worse
http://forum.xda-developers.com/showthread.php?p=52142798
Ever since 4.4.3 USB charging has been slow. Wireless charging is 2x faster.

Exactly the same problem after 4.4.4 update.
Am having problems charging my nexus 5 since last night.
I reflashed the Kitkat 4.4.4 rom on my nexus 5 from lollipop after i couldn't stand the ram issue lollipop having.
The following night my battery was at 20% and i left it charge overnight and i woke up finding before going work, found that the battery was still charging at 20% .
I tried with the original charger plug and cable and also wireless charging qi nothing charges and phone is losing percentage and have to keep using from the mains to keep the phone on.
When i use the usb cable or qi charger it says charging on screen then it goes not charging.
I tried re flashing 4.4.4 cleared the cache and tried different usb cables and wall plugs the problem still persists.
I replaced the battery beginning of March this year after i had this phone since launch day and new battery was fine.
I believe its either hardware or software problem causing this.
Please any advice or methods i can do to solve this problem would be nice.

That really narrows it down
Did you try charging when the phone is off?
It shouldn't be hardware if all you did was downgrade. The boot loader shouldn't influence it

Yes i have tried charging the phone while the phone was switched off for an hour but it shows battery icon empty and still charging
I'm facing this problem right now. Did you figure it what was wrong and fix it?
Is it possible that there is a loose connection inside the phone? Is the phone recognized when connected to a computer? Maybe a damaged USB port, cable, or charger?
Alright, so here is a fun issue to deal with. My notepro has always been a little slow to charge, but most of them are. However, its gotten very bad.
I have had issues with screen flicker and a little heat issues and some other small things off an on. So, fed up with it, a few days ago I rooted the tablet. It worked fine. Then I tried to install a new kernel and rom that was getting good reviews. However, when i did this, I couldnt get past the boot screen. Several reinstalls of stock and customer kernels later, my tablet started flashing and eventually died. When it was plugged in, it would show the battery icon with a circle in the middle but then die. Several tries to fix only seemed to solidify the tablet's fate.
However, yesterday I gave it another shot. I assumes the tablet had heated up and made the solder loose, so after a while it was solid again. It started charging, and after reinstalling stock rooted rom and stock kernel repeatedly, it was working again. I then installed the rom and kernel I was trying to before (I had to have a custome kernel to be able to control voltage for the screen flickering issue).
Now it is actually working. All functions are working, and oddly enough I am not seeing any screen flickering.
Only one real problem remains. Battery charging. The battery is charging so slowly that when the tablet is turned on, it doesnt charge at all, it creates a stalemate between charging and draining. It also drains pretty quick. The power drops about 5% in about 5-10 minutes of full screen brightness use (I was testing it this way to try and see if it would flicker again.
Its been charging for about an hour now, and only gone up 5%.
I have tried a couple cords and different bricks, but to no avail.
There are some thoughts, I am wondering if the tablet is only drawing power as if charging from usb, so only around 0.5a instead of 2.4a or so . I am also wondering if there is still a hardware issue.
I do not think it is the rom or the kernel, as this issue was happening as well after I got the tablet working again on stock but before I tried isntalling the rom/kernel again.
Any suggestions? I would be very appreciative.
I had simular problem with very slow charging, reboots and bluescreen. I opend my note to check battery plugg for broken soldering, but I found no problem with it. But to check turely i unplugged battery from main bord and replugged it again. After that I had no problem at all, now its charging normal, no reboots.. stil working perfect after averyday use for about 8 mounts......
If you are using usb cord not usb3 cord it will charge very little when using tablet . Mine will charge when off and below 25% to full in 7 or 8 hrs overnight.

Could be a bad charging port dock/flex cable. These are actually pretty easy to replace and can be found on Amazon. I had to replace one on mine. Try searching for a usb charging port dock flex cable for samsung galaxy note pro. That will cause the issues you are seeing. However the screen flickering sounds like a voltage issue caused by a cracked solder pin from the battery connection to the board. Which is very common on these and hard to see without an electronics magnafication glass. You could try taking the back off and pressing the battery connection firmly while plugging in your tablet and powering it one to see what happens. Either way sounds like a hardware issue.

Ok Guys, had the same problem with my 12.2 samsung tab pro, changed usb chargers, cables etc.
Found that the connector on the tablet itself (female) did not made good contack with the male usb.
So i simply , very careful, with a pair o pliers closed both tips on the usb conector, so the cable enters more tight. And voila, the usb amp meter i had showed a rate of charge from .33 amp , jumped to 1.73 witch is more than enough to charge and use tablet at the same time.
You need to do this at the end of the cable that plugs on the tablet, that is kind of double, maybe a e.0 usb or something like that. Make sure to close both tips. You want a tight connection
Hi guys,
I haven't been able to charge my phone properly for a while - after reset when I plug in the original charger, it charges fast, when I unplug it and plug it back in, it charges slowly. When I unplug it again, it still shows the charging icon forever but it won't charge when plugged in. Factory reset doesn't help. The phone also randomly shows the USB moisture message even though it never got wet. Changing cables and power sources doesn't help.
Build MHA-L29 8.0.0.375(C636)
Thanks for any ideas!
Blow out the USB charging port on the phone. Also, use a toothpick to GENTLY clean out the port of lint and dirt.
And use app that tracks your charging speed. Try ampere In playstore.

Thanks for the reply. I tried that already. Is it possibly a battery issue? I wouldn't mind replacing the battery, which is cheap rather than replacing the phone because of such nuisance.

Thanks, good idea.
Ampere clocks in at -250 mA after reset. Goes to around 1800 when plugged in to a third party charger, which drops to around 300 mA when unplugged (phone indicates that it is charging). After reconnecting it goes up to 1000 mA. I don't have my Huawei charger at work but it's similar - at first plug in it charges fast, after reconnecting it switches to the slow mode.
You should use your original charger. And see if supercharge is working. If not. Give it a shot in a service center. Theyll fix your phone for free if you still have warranty.

Well, before replacing the battery, try this:
- turn phone off
- connect to original Huawei Supercharge charger and charge up until 90% or so
- disconnect from charger and turn on
Use the phone as you normally would until around 35-40% remains, then try connecting the charger. If the issue persists, I still believe it is a problem with the charging circuitry rather than the battery. Especially if we take the moisture in the USB port message the phone shows. Replacing the USB charging circuitry should not be a big problem AFAIK, it is connected to the motherboard with a snap-on connector, replacing it should be easy as disconnecting the connector, removing the circuit with the port and placing the new one in.
Yep, I guessed it: https://www.youtube.com/watch?v=4avHFWjsz4k
Are you having issues where the phone is displaying 30 or so percent battery remaining, but the phone shuts down?

That's a great point. I didn't know the USB circuitry can be replaced by itself. I don't have any issues with the phone switching off. It uses the battery all the way down to 1% or so. I don't see any erratic percentages. I'll replace the part and update you on what happens. Thanks!

Make sure your microphones still work. I had to replace my USB charging board (which also contains the mics) recently and the first one I tried had a bad mic. I could make phone calls just fine, but google assistant couldn't hear me. I got a replacement and both mics were fine.

I wish I could close this thread but a lot of weird stuff happened since I "fixed" the phone.
Since I bought the battery before I was told it could have been the USB board, I replaced the old battery too. The first charge was smooth and I drained the battery to 0 as recommended. I plugged it back in and it charged to 5% and stopped. I noticed a chemical burn smell that I later realized was coming from the USB circuitry. At this point there was no way to charge the phone but when tried to turn it on, I still saw the red charge icon. I opened it up and put the old defective USB board back in and I was able to charge it. Throughout the day I noticed weird battery drain that I saw recently before the replacement of the USB board. As usual, I tried to restart the phone to fix that but it won't turn on. The battery was at 85% when I shut it down. When I try to turn it on, it won't even show that red charge icon. Nothing. I can't put the old battery back to see if that's the problem, because I bent it during replacement.
Could it be a battery issue this time or is the phone just dead at this point?
