Hi [MENTION=6330191]sonu42197[/MENTION]

I assume that after rooting, you want to install a custom kernel anyways.

With this Kernel you have auto-root included for almost every variant, including your I version :)

Hope this helps!

I tried this kernel but i got stuck in a bootloop. Plz someone help.

My tablet came with 4.4.4 and win8.1 bing. Later on i updated to Win10 and 5.0 with Mirek's rom. Chris did a post on the inaccurate battery on Win10, but i can't find anything about android.

http://techtablets.com/2015/02/x98-air-3g-battery-meter-fix-7-stuck-issue-one-cell-reported/

With the stock rom i got an awesome battery life, almost 8 hours of SOT with my personal usage.

http://i.imgur.com/gnXPD2Q.png

Then i flashed Mirek's rom the battery issue reveled itself. I'm sure that his rom has nothing to do with this.

It's the same thing like in Chris's post, i lose a lot of percentage pretty quickly then it stuck around 7% and i'm still able to use the tablet for 2 or 3 more hours. I tried to do a good old battery calibration, but no luck there.
[Teclast X98 Air 3G] Seiya0890:
Actually I have the same issue, but could not find the solution :/ . I was wondering if it would not be better to just a buy a new battery one with 12000mAh so that I can get even more usage time.
[Teclast X98 Air 3G] mr.pants87:
I had the same issue, I just went back to 4.4.4 and haven't had the problem since.
[Teclast X98 Air 3G] kosrica:
I have the same problem under bios 2.02 and mirek's rom lollipop 5.0. Interesting thing is that at the beggining this problem didn't appear after immediately installing the rom somewhat it appeared at a certain moment but I don't know what was the trigger. So as far as I understand the only fix is to revert back to 4.4, it's ok to keep the same bios 2.02 or I have to revert back to original 1.07?
[Teclast X98 Air 3G] S0und_:
Did you got an answer for the bios question? I'm giving few more round for Mirek's lollipop 6.0, and i will roll back to 4.4.

I don't have a screenshot, but i was able to use the tablet for 2 more hours after that, and still had juice in it.
[Teclast X98 Air 3G] S0und_:
Did you went back to bios 1.0, or you kept 2.02?
[Teclast X98 Air 3G] kosrica:
Please let me know if the problem persists in Mirek's rom 6.0, I think it will appear because as far as I understood is a bios problem...
[Teclast X98 Air 3G] Seiya0890:
It persists.
[Teclast X98 Air 3G] SlayEngine:
Which BIOS do you have? I got the same problem. Android "destroys" the battery-metering.'

I'm on BIOS 2.05 and Mirek 6.0... Unfortunately.

When did you buy your tablet? I think its a manufacturing problem (by teclast).
[Teclast X98 Air 3G] trust_bcn:
I have the same problem with a C5J6. At the beginning, the meter was correct. After update to Mirek Rom, the meter was innacurate (ok from 100% to 40%). I've updated to a Stock rom again an the issue persist...

I have battery problem in my tecladt x98 3g c5j6

The battery works well till 50% then it drain quickly till 1% then last several hours . the problem happened in stock ROM android 5 and mirek's v6 ROM either . any solution ?
[Teclast X98 Air 3G] SlayEngine:
Same for me. It worked well 'till I flashed Mirek's 5.0 on C5J6. Maybe we have to flash the older version (Anrdoid 4.4.4) + flash the BIOS again to solve the problem. Anyone tried?
[Teclast X98 Air 3G] S0und_:
Like it or not, but this issue is goes back to Mirek's rom, even if i'm on 4.4.4, the problem is still there. Sadly not even the stock rom can fix this. :\
[Teclast X98 Air 3G] S0und_:
which bios? can you be a bit more specific, like step by step?
[Teclast X98 Air 3G] trust_bcn:
I hadn't update the BIOS with the Mirek190 ROM. I only update the ROM

Enviado desde el móvil
[Teclast X98 Air 3G] SlayEngine:
Maybe with Mirek's 5.0 or 6.0 the BIOS has changed especially the metering system got damaged. So perhaps flashing again BIOS 2.02 after installation of old ROM (4.4.4 or Stock Rom) can fix this issue? I will test it in a few days. I don't know whether it will work.

The problem is also that I can't find any solution in any forum online. Doesn't look good for us.
[Teclast X98 Air 3G] melmarghaney:
I mentioned in this post that I've the unusual drainage in battery stats below 50% and that happened in stock Rom which was android 5.0 fisrt and then happened also in Win 10 , I flashed mirek's V6 Rom and the same problem persist .

I bought the tablet in October and it's model is C5J6 comes with android 5.0/win 10 , bios 2.05 .

Is it possible that it's a hardware problem regardless the software installed because the total discharge hours of the battery is normal but the battery stats is the problem here , I've tried to use battery calibration apps but with no result .
[Teclast X98 Air 3G] S0und_:
This was my first and only run with the stock 4.4.4 when i got the tablet. As you can see it's totally fine. The most annoying thing is that i'm unable to get nearly as high SOT since i moved to Mirek, thanks to the wrong battery reading. So imo this is not just a hardware problem.

http://i.imgur.com/HzDozSy.png

Edit: weeell maybe i'm wrong, if you check the image there is a huge "wall" near to 40%, so maybe idd a hardware problem.
[Teclast X98 Air 3G] stm00192:
Hello everyone,

I had the same battery meter problem also and unfortunately Mirek's lollipop ROM was the problem.

But there is a catch! If you simply go back to 4.4.4 stock rom the problem does not go away! You have to follow a certain procedure! (Tested on C5J6)

The first step is to follow the known battery discharge method to restore the battery meter in windows as follows.

-Boot to windows

-Run (powercfg -setdcvalueindex SCHEME_CURRENT SUB_BATTERY BATACTIONCRIT 0) in elevated cmd and then fully drain the tablet in windows until it shuts down.

-Let it charge while off overnight (at least 8 hours)

-Boot to windows and verify that the maximum capacity is reported a little over 30000mwh with AIDA64 or HWmonitor. (If not, repeat the previous steps until you get it right)

- Hard shut down by pressing the power button for 15sec.

-Boot to dns mode (by pressing Vol+ Vol- Power button together) (

BE CAREFULL NOT TO BOOT in Android

else you will have to repeat everything!!!)

-Flash the stock rom 4.4.4. found here (h@@ps://mega.nz/#!cAgwQZRK!8tyuToPfnXq3EE8ZB7zEB3mR2RLRnFjaIvWJvQfqNCc) (replace @@ with tt for the link to work)

-Let it boot to android.

That was it!! The Battery meter should be back to normal and will not go bad again if you boot to windows and back to android!!! Chears!!

If the battery meter problem annoys you as much as it did me then you have to live with the stock ROM!

I have not tried if this works with the official lollipop rom so if you do, please report back.
[Teclast X98 Air 3G] S0und_:
thanks, i will try this after work, if i can find a stock 4.4.4 for HG9M Air II
[Teclast X98 Air 3G] SlayEngine:
Did you try Mirek's 4.2 4.4.4 ROM?

Many users reported, that coming from 4.4.4 going to new Mirek's 5.0 pulled the trigger for the malfunction of the battery metering.

Thanks anyway!
[Teclast X98 Air 3G] stm00192:
No I didnt try mireks 4.4.4
[Teclast X98 Air 3G] melmarghaney:
I'm testing this method on the Tablet now and I'll post the result after complete discharge the battery to see if the battery stats problem still there or not , hopefully not .
[Teclast X98 Air 3G] S0und_:
Can you check the battery capacity with Aida64 on android? My bugged was around 4960 or something. Which makes sense, since we experienced the rapid battery drain around ~40%, if the battery is 8500, 60% of this capacity is 5100.

[Teclast X98 Air 3G] S0und_:
For reference, this is how Aida64 looks like on a "normal" Mirek 4.4.4
[Teclast X98 Air 3G] beardedwonder:
That's the same as mine running the latest mirek ROM.
[Teclast X98 Air 3G] melmarghaney:
The first thing I want to talk about is battery capacity that showed in aida64 . The capacity shows that it's 4980mAh in android 5.0 either in stock rom or mirek's rom and also the same in android 4.4.4 stock rom . That makes sense because when I monitor the discharge rate in the app the average is 650mAh and the total discharge hours is about 6/7 hours and when we do the math we come to the actual capacity of the battery is 4980mAh and not what has been advertised 8500mAh , unfortunately we can't remove the battery to make sure of the actual capacity but with the previous facts we can be certain that it's not 8500mAh .

The second thing is I tried the instructions that I quoted previously and it worked , no problem in battery stats in windows . I ran several discharge cycles without errors . I tested the android interface and switch from android to windows without errors . I noticed that the battery life in windows is better than android and that because the higher CPU frequencies of the quad cores in android so if you want better battery discharge period stick to windows , I'm talking about windows 10 .

The withdraw in that solution is you have to deal with the stock rom with the annoying bloatware but that's the price .

I wanted to replace the stock 4.4.4 rom with mirek's but I had touch problems with it and I think that it won't work like the stock rom , if anyone try it give us the results .
[Teclast X98 Air 3G] stm00192:
The battery is actually around 8000mAh.... The 31000mwh reported in windows corresponds to 7800mAh if you do the math.

The reason that it is reported as 4980 in Android is unknown to me though.
[Teclast X98 Air 3G] jagr:
is it possible to remain on mirek 5.0 rom but do the steps to get the readout updated?

i never installed mirek 4.4 previously, went straight from stock 4.4 to mirek 5.0, battery shows 4850mah on aida64.
[Teclast X98 Air 3G] melmarghaney:
If you mean the steps to solve the faulty battery readings , the Mirek's Rom won't work . Till now it works with the stock 4.4.4 Rom and apparently from the replies in this topic , Mirek's 4.4.4 Rom won't work either .

The 4890mAh reading is exist in all the roms .

I just flashed stock 5.0 -> BTW if you have trouble to flash the stock roms with the Intel Manufacturing tool, it's a driver problem. At home i'm on W10, the flash didn't worked, but i was successful at work with W7.

I didn't noticed this yet, but no wonder why Mirek's rom's battery is f*cked up. Not just it doesn't knows the max capacity, but can't access the discharge rate as well.

I didn't "reseted" the battery in W10 yet, that's the reason why the max capacity is not showing.

Hello, Im the owner of an Air III Dual Boot with the same problem. This is pissing me off and I just wanted to know if the metod could work with the same steps but flashing the own Air III stock rom...

The drain happens even running in Windows 10. Never flashed other rom. All is stock, so probably the swith between both OS could have miscalibrated the battery?

The weird thing is that this is happening in both systems...

[Teclast X98 Air 3G] S0und_:
I'm having trouble reseting Win10 battery, i did used the command in an elevated CMD window, discharged the tablet running benchmarks constantly, it did turn off. Turning it back on i got some error, so the battery is low, but after doing the discharge procedure twice now, HWMonitor is still reporting 19828mWh, instead of 30k.

Also i left the tablet to charge overnight, so it had definitely 8 hours of charge time. When the battery is charged, the charger gives out this high pitched noise, and i heard that when i unplugged the device.

I'm on BIOS 2.05, and i flashed debloated lollipop rom directly (without even booting to windows) but Aida under android still not reporting the full capacity. Which makes sense because as i mentioned, win still shows a wrong report.

Any advice?

I have full discharged the battery in Windows, it took 1,5-2h at 0% with full brightnees to shut down itself. Then I left the tablet charging all the night. At the morning, it said 100% (last times it didn't went more than 99%, so I unplugged it and booted again in Android.

Did you Flash the stock 4.4.4 after resetting the device as mentioned in the instruction above?

Where can I download the stock ROM (4.4.4)? Can't find any link for C5J6. Is it universial for all models? Got the 4.4.4 for C8J7. Thanks!

4.4.4 at the moment.
[Teclast X98 Air 3G] S0und_:
I think i found the solution. So when you set the:

powercfg -setdcvalueindex SCHEME_CURRENT SUB_BATTERY BATACTIONCRIT 0

basically what you do is, you set the critical battery action to: Do nothing

So this way you can check if the command is working for you or not.

Here is the thing what i did to solve my issue:

When the tablet is "fully charged", and you hear that high pitched sound from the charger, truly, it's not fully charged yet. Unplug, and re-plug the tablet, and keep charging it. Because you can charge it a bit more. You have to repeat this process multiple times. Do this til when you replug the charger, it will do that high pitch sound right after.

This is a ****in joke, i managed to get 30k mWh once, since then i'm unable to discharge the tablet and get the correct value.

After self-shutdown, is that fine that the tablet boots to the OS change screen, instead of booting directly to W10? Honestly, all i want is a functioning Android, i don't care about W10 at this point.

The most annoying part is that now i have to discharge the sh1t, charge it back, and hope...

One thing that bothers me, that W10 is bugged, i mean sometimes didn't load the taskbar fully, you can't access the notification panel, the whole screen flickers.

[Teclast X98 Air 3G] siezed:
Well, theres two separate issues, battery drain and inaccurate battery*meter, battery drain only happens when the tablet is in sleep mode in windows, inaccurate battery meter happens*in windows*and android intermittently.*

If you're talking about battery drain with windows hibernation, you need to update to the latest bios, instructions on that are somewhere*on this site and fairly straightforward.

If you're talking about battery meter, where the battery drains fast to 5% or so then lasts for hours, mireks newest rom seems to have fixed it for me for android, so try reflashing that. Windows the only workaround I know of is to install battery bar, and if it reads 14,000 or so you know you have an inaccurate meter and 5% battery is actually 50% battery, if it reads 30k or so, you have an accurate meter and the % is the actual percent.

This (inaccurate meter) issue has been with us since the release of this tablet, and even the brightest of us cant figure out a reliable fix. We know its something to do with the dual batteries in the tablet, and the bios only recognizing one battery sometimes, but beyond that its a mystery. * **
