Hello all.
My problems started when my battery would no longer fast charge and would then only charge to 15%.
It doesnt progressively charge, it goes from 0, and suddenly says 15%, and stays at 15 for hours, untill it decides to turn off without warning.
I replaced the charging assembly, to no avail.
I checked the phone temperature, a constant 50 degrees, never changing even when the phone is cool to the touch.
I believe the temperature sensor is malfunctionning and is stopping the battery charging.
Ampere tells me
Health : Good, voltage: 7.4V, 500mA charging.
Does anyone have any information?
A similar post exists https://forum.xda-developers.com/t/battery-stuck-at-15.4528403/
Someone on this post claims it is since a software update. I will try resetting the phone.
Edit, I repaired the issue, the cable between the motherboard and the charging system was faulty.

Hi !
I had 2 Problems (running Win 8.1):
First: it only charged when OFF, not when windows booted.
Then: NO Charge at all after playing with a USB Hub (nothing defective, just unplugging and replugging).
I solved the NO CHARGE Problem this way:
I opened it, unsoldered the battery (easy, 3 wired, PLEASE isolate them, do NOT short the wires).
Then i sortened (bridged) the 3 solder "blobs" on the PCB with each other to drain remaining capacity from the "confused" charger chip i wanted to reset.
Then resolder battery, BAM, it works again.
My first problem remains --> only charging when OFF, but as i now have an AMpere meter conneted all the time i guess i have the solution !
My battery profile has a low brightness, my "powered" has a high brightness. So if the X98 detects the charger it starts charging (i can see around 1 Amp flowing) and turns up the brightness. BUT the bright screen drains so much power that the Voltage drops and the charging circuit senses that and thinks chargin is over and stops charging.
If you have around 75% brightness this goes on & off forever, my Ampere meter jumping between 1 Amp and 0 Amp all the time, brightness going up and down.
Solution (Well workaround): Set the "powered" brigthness to a low value and ENJOY charging.
Maybe Teclast can solve that via Firmware. If they care...
Greetings,
Nils
P.S. if that helps or you have a better Solution, PLEASE post here so we can see if that is just me or if this is a general situation !!!

I was having problems charging. After I restarted it began to charge. I also turned the brightness down. The charger sent is US power to usb adapter and a very short usb to micro usb cable. The volts and amps don't match my other chargers. I plugged the adapter with a longer samsung usb cable. Hopefully it will charge fine.
I have another problem. While charging my tablet shuts down due to thermal issue.
Hlo deep singhal, can u please contact me. I am from haryana, india & interested to buy x98 air 3g 64 GB. Please leave ur Phone no. If u can.

Hello, I have the tablet since two weeks and also had the thermal issues. Random shut downs in Windows while charging and freezes in android while playing.
When I got the tablet I updated directly to Windows 10 and android 5.
I followed the instructions from techtablets and made a hardware mod. Since then the tablet works as it should. There is the risk of bricking the tablet! This works for air 3g and the new pro as I understood, maybe for your tablet also.
Teclast X98 air 3g ii
My tablet continuously restart
not charge when it on then set low brightness.
Please help in start my tablet.
Regards,
Pradip Algottar

So, after using the tablet for a (long) while, it always shows that the tablet is charging.
I charged the tablet after this first encounter, while it was off, booted up and the battery is empty after ~15 minutes.
And also with removed cable it still shows that it is charging.
Does anybody else have that problem?
I do, i have an air ii that i bought on ebay and worked well for a few days, but now it gets extremely hot, and sometimes charges, sometimes it does not. Just like yours, sometimes it shows that is charging, even with the cable disconnected. If i dont get a refund, i don't know what im going to do.
charging problem after replaced battery
I just replaced the battery wich sais 3.7v instead of 3.8v was the old one. The problem is that it is not charging at all, even if I shut down. Do you know why?

anyone please?
So like the title said i have replaced the battery in my P9, with an original battery. It has the same part number and all that. I have noticed that the phone won't charge the replacement battery, i have returned the new battery in warranty and revived another one. Same thing, the phone starts up as soon as you plug in any kind of power source to it , like a charger, but no charging notification. The notification light pulses in rare intervals (some thing of 10 secs or more) but it's not steadily on like when normally charging. And the most vexing thing is : if i replace the original battery it charges. Unfortunately the the original battery now has the bad habit of cutting out on me at random from anywhere 47% or bellow .... The phone is nearly 3 year old now.
Have you given the new batteries some time to charge? Maybe they were delivered to you fully discharged.
First one was on 85% the second on 60% or so. I kept the 1st one on charger for a whole weekend... Still nothing
Have you tried to callibrate the original battery (you say it suddenly drops if below 40%)?
Yes, I have allowed the battery to run down to 3% and the phone turning itself off. Then fully charged it while being off. So the original battery is just plain old, nearly 3y old. The problem is that the phone refuses to charge the new batteries regardless of original charge. Also it turns automatically on when you plug in a charger, not just showing the charge animation. That is not normal behavior.

I've done that after reading you'r message , but i have already done the steps not req root. And i'm not willing to root my phone.
P9 also not charging
Did you manage to find a resolution to this issues? I'm having the same problem with my P9. I changed my battery, and it now won't charge. It turns on ok, and everything seems to be working. When I plug in the charging cable, it makes the sound it usually does, the battery symbol flashes green but instantly turns white again. When the phone is off, plugging the cable in switches it on, but no charge. I've had two replacement batteries, both have the same issue. Also, the original battery is now doing the same. I'm wondering if I damaged something while removing the battery.

I think it's problem in charging IC or port.
Hi all
Had same issue with replacement battery
After replacement battery isn't charging. Problem is in bad connections
(probably from long shelf storage connectors got rusty)
Voltage was fine but temperature reading was way off (very low -2) and phone didn't charge battery
Problem is that there was no error message about battery temp.
After cleaning the contactors battery reading became normal and it started charging
Anybody ever had any solution to this problem? I have the same issue. Battery replaced - not taking any charge. If micro USB charger plugged in - the phone turns on. If it is already turned on plugging in the charger the screen flashes the % of the charge and nothing.
My phone is behaving weirdly.
Whenever I use the original fast charger to charge the phone, the data cable stops working from next charge onwards. It's damaged 4 cables so far.
Sometimes it doesn't charge despite being on charge and showing the same status. In fact the battery keeps discharging (e.g. put on charge when battery was 57, it becomes 53 despite showing charging status)
I know going to service center is the last resort. If anyone has any suggestion, please share.

Please observe the attached screenshot. Despite the battery showing plugged in on status bar, the CPU Z shows battery is not charging.
When in charging this device heats a lot, though it can charge through only a 15W charger. Even when battery is charged to 100%, it does not stop heating. I checked the temperature after 20 minutes from the time device was charged 100%( the charging cable was connected), But felt the same amount of heat even after it has been some time. Doesn't the phone come with overcharge protection?? My last device was poco f1 and it became super cold just after 10 minutes as it has been fully charged. Anyone facing the same issue or is it just me.
For now I do not have any issues related to overheating both during the charging or phone usage, however my battery drains a lot faster with Google app consuming as much as 20% in the background. If you are charging the phone overnight you can try disabling the Fast Charging mode and see if the overheating is still there. I do not have idea about over heat protection.

Do you have same issue still?
For me, after battery reaches 100% the phone eventually cooled down.

This problem does not occur anymore. I think one of the updates fixed it
Hello. I found some interesting problem? in my XZ1C. When i charge battery to 100% on turned on phone till full charge and next shut down without unplugging charger it indicates 88% and keep charging to 100!. I thought my battery slowly dies. Now i see it is about 12% more potential in it xD.
I run Havoc 4.6 maybe that is the reason. I wonder if you faced the same problem and know how to fix it. Charging on shutdown phone is a little bit irritating.
Perhaps this is such a case where the device manufacturer protects the battery from harmful charging to full.
