Hello all,
I'm experience a little trouble by WMWifiRouter.
I think I find a power management bug because this behavior is very weird.
When run WMWifiRouter and the phone is plugged in by AC Outlet, sometimes it will trigger discharge mode. So, my phone will be plugged into the wall and at the same time it will be draining the battery down to 0% from full charge very rapidly.
It only occurs if WMWifiRouter is running - so the wifi will be on, BUT even if I shut down WMWifiRouter and switch off hard switch wifi on side of phone, my phone will remain in discharge mode until I reboot the phone.
When the phone reaches 0% capacity it will shut down even though it is plugged in by wall.
This occurs with wall adapter, USB cable, and XV6700 car charger. All the same.
Since the battery only has a finite amount of discharge/charge cycles, I want to be very careful about this issue so I don't destroy the battery. Also, I can't use direct USB cable for tethering because every five minutes or so, I must disable ICS and then restart ICS since my computer enters USB power save mode which causes loss of connectivity, and this is a little inconvenient.
Only solution is WMWifiRouter, but by use this, my phone will discharge completely in maybe 30 minutes if I try to use it while plug to wall.
Sorry for the long post about this issue.

When your phone is plugged in, is the orange battery light flashing or steady? Normal charging should have it steady. If it is plugged in and the battery isn't charging properly (because it's too hot while wifi is on) then the light will flash, which means it isn't charging. Since it's not charging, then it's your wifi that's draining your battery.
Having wifi on makes your battery very hot, and at some point, it may stop charging.
When I use wifi and need a charge, I plug in a USB cable to my laptop. It doesn't seem to get as hot.
Overheat Mode
When using WMWifiRouter, the battery drains quickly.
1. Make sure bluetooth is off.
2. Make sure beaming is of.
3. USB charging is too slow to keep up with WifiRouter
4. Plus phone into the wall
5. Slide keyboard open to release heat quicker so the phone does not go into discharge mode.
6. Enjoy
I just tried your method Ectropian.
By plug to wall and slide open keyboard, it will dissipate heat quickly and won't enter discharge mode. So, this is a fix and I am very thankful for your help!

I have found that USB charging is fast enough to keep up. The phone overheats.under some circumstances it can even overheat during a normal phone call. Im trying to get a small fan for it. I plan on using a fat back battery cover for an extended battery,and wiring it to the battery terminals. I will drill some vent holes in it and connect it with a temperature sensor. It will add some thickness to the phone,but should not effect battery life as the fan wont turn on until it overheats.
Unfortunately the 3mm thick fan I want is only available in quantities of 200. I will probably have to go with a 5mm thick fan for now. I dont know if it will fit under the back though. Does anyone have one of the thicker batteries they could accurately measure for me?
Does anyone know how to set up a password for WMWifiRouter so it is a secure network and no one else around me can use my internet?

In addition to these good suggestion, I have find that if you also
a.) Remove stylus from stylus slot, and
b.) Turn the phone upside down while WMWifiRouter is in use,
It will dissipate heat even quicker.
You see, stylus to the XV6800 is made by metal, so,, it conduct heat and hold it in that stylus hole. Take stylus out, heat escapes through hole instead of build up by metal stylus rod.
Also, back of keyboard is metal, so turn it up, and air pass over it and remove heat too. (Make sure keyboard is slide open when turn upside down, as previously mentioned by Ectropian. This will improve air flow to heat conducting areas.)
Hope it helps everyone else like it helped me.

When you setup the new adhoc connection in wilan settings/comm manager/ (need to have the wifi ant on when you do this) in wm6, you can setup the network name and key.
I want to set up my SSID next time i'm sitting in starbucks for all the people that bring their laptops.
Network name/SSID:
Ask the guy with the coolest phone you see for the network key.
read the wmwifirouter thread. Chainfire addressed this issue by making the "unattended" mode. You can and should hit the power button and turn the phone to standby while using wmwifirouter. This saves enough power so the wall charger can keep up with the drain... maybe even the usb charger. I think very few people if any agree with the opinion above that the usb charger is better. The consensus is that it's the amount of power the charger can deliver that's important more than the heat... of course more power is more heat.
Batteries charge more rapidly when they're closer to discharged. Before using the unattended mode... (could maybe happen wth an older battery too) I found that if I disconnected and reconnected power after dropping below about 70% that charging would kick back in and then be more likely to keep up.. holding the charge steady at about 70%. Above this, the charging current probably dropped below the usage current. With the unattended mode it is fine even at 100%.
Edit: Let me make this more clear. A given charger can provide more current because it has a lower internal resistance and lower voltage drop under a current load. Increased charging current increases heat which may increase resitance within the battery and charging circuits and in turn limits charging current, even if the heat isn't increasing the resistance is a sign that lot of power is being lost to resistive losses. It may be that the dominant resistance is due to the device itself, not the charger and that a better charger won't help, but it's silly to say that a better charger will make it worse.. if it's getting hotter it's only beacuase it's charging with a higher current... which is a good thing (at least until the divice is actually damaged). It may be that internal limitations keeps it from charging at a significantly higher current so the wall charger might not do significantly better, but it can't be worse... if it was worse... it wouldn't be getting hotter.. it would be cooler(because of less charging current)... unless maybe there's actually a thermal cutoff? I suppose that's a possibility... but still the end result observed should in that case be that the phone seems cooler after hitting the cutoff, albeit not charging if that's the case.

There is in fact a thermal cutoff. The problem that many people,including myself experience is that while the phone is charging,and the battery is getting hotter,the phone is also producing heat. The battery gets so hot that the thermal cutoff trips and the battery stops charging. I tested this with a can of compressed air and confirmed it was a heat problem. I then placed the phone on top of a small fan,with the battery cover off and the phone ran all night long without over heating. When I dont have it on the fan it overheats,stops charging,discharges and shuts down. Opening the keyboard and removing the battery cover helps,but it does it still,it just takes longer.
Well I guess as with most things on these phones.. there are different results for different people. When mine starts flashing it doesn't seem to have cuttoff charging.. but rather just indicates it's not quite keeping up. The wall charger gets hotter.. but the flashing never happens with it.
I'm a little surprised about this strange cuttoff behavior for several reasons, but there are too many unknowns... I guess we better stick with what's observed.
The powersave battery hacks help ALOT. It's also clear that (at least with powersave hacks) the more data rate you use, the more power it uses. If yours is getting that hot "overnight", then either you aren't using the powersave hacks, your phone is broken.. you're continuoulsy downloading stuff for hours which could lead me to guess full data capacity full time, or running a server of some kind with at least some significant use. If it's something like the last two, I guess I'm not surprised some modifications are required to get that kind of steady performance out of a little pocket device. I've had actual wireless routers overheat and lock up in such conditions. It's a phone not a cisco. Still if your fan can make it into a cisco.. then that's kind of cool.
OH yeah.. also I turn down the wireless power all the way in the settings, but that actually doesn't seem that important, not sure.
I have been searching for a solution to this as well. I have all the power saving hacks and everything on my mogule and mine still overheats and eventualy dies. I found another temp solution, I put it on an ice pack and it doesn't have the problem..lol
better idea than ice pack (I know this is a year old post but owhell)
better idea,.... ice pack could void phone with H2O.
Throw tha ***** in to the freezer and call it a day!

Its not a Cisco? Ive been using it like that for years. Seriously,I have.
I actually use mine in my truck and the nice thing about it is I have a phone holder that clips on the air vent. So while running WMWifiRouter on the road for our laptop I just keep the AC on the back of the phone and no heat issues or charging issues.
Hi,
i have got a problem in the charging circuitry of my LG G2 LS980. The problem started as i left the phone on charging over-night and it was super hot in the morning. Also it was not charged to 100 %.
Since then its temperature is too high when ever i plug in the phone for charging. also the rate of charging is decreased significantly. it takes upto 12 hours to charge. I opened it up and i found that the component highlighted in the picture gets very hot. i want to change this component (which appears to me as a capacitor), but nothing is written on the component (no rating or part number).
Can anyone please comment what it is ?
It is in the charging path so it must be a current limiting diode, capacitor or something.
Please advise something for it......
Sounds like thermal daemon migration and high temperature maybe off? Go to dialer, then type 3845#*802#. This should open up a menu. Scroll down, then click on each one, and.make sure the toggles are off. Hope this helps. Good luck.
Hello,
i had resently installed a Nexus 7 Tilapia in my Car.
I had removed the Battery from his own Circuit Board and conntected it to a DC-DC Step Down Converter (10A) with a Output Voltage of 4.25 Volt.
After some time of Useage the percent of the Battery slowly decreases, but the Voltage stays Stable.
Does someone know how to fix that?
I want to Keep that board because of the Battery Display (100%) and the Clock.
Thanks.
Hello there .were you able to fix this issue?i am facing the same thing right now in grouper.it was drawing battery,so I connected the tablet directly to my car battery with dc dc hoping to solve the problem but instead the percentage keeps dropping and I have to disconnect the pcb board (battery board) and restart the tablet.i see 100% and then it starts dropping ?
hello, no i dont. that peace of shi* broke down, so i trashed the whole project. sry
Hy all,
i've got the Yoga Book YB1-X91F Windows10 pro.
I've changed my battery.
Now is the problem,that windows automatical shut down after few seconds.
It show a thermometer on the screen befor.
What can i do to fix this ?
Many thanks for all helpfull tipps.
Regards Dete
Hmm it is weird cause I ain't got any problems with battery
which is the best in 2020? android or windows version?

I have the exact same problem. New battery, overnight on the power cable, boots up fine. Then after a few seconds, and with the battery status showing 100% it declares low battery and the excess heat icon before automatically shutting down. It does not display the behavior in Safe mode, but I can't check the battery in that state so I don't leave it running for long.
Has anyone else out there encountered this after replacing a Lenovo Yoga Book YB1-X91f Windows 10 battery?

Your battery is not Lenovo offically. It only works on android yogabook(yb1-x90f). You can rename LenovoShutdownService.exe(?) on C:\Windows\system32 to prevent windows shutting down. But you can not charge your battery while windows is running. Charging battery only works while windows is not running.
But I found this battery on taobao. It can charge while windows is running. https://item.taobao.com/item.htm?spm=a1z09.2.0.0.46792e8d0NWTpv&id=652131598092&_u=aue0c7jeb27
scott_lai - great tips! How did you discover the workaround - and the alternate battery source?
Posting a progress report since soctt_lai's suggestions. I took his hint to disable the LenovoShutdownService, but rather than rename the executable, I simply disabled it in the Admin Tools/ Services list. I also managed to install the most recent Intel Battery Management driver dated 2017. After installing a YB1-X90F (Android) battery, it appears to take a charge, as I can leave it on the charger all night, and run unplugged all day without dying. The battery monitor doesn't know what the battery status is (reports 100% and never changes), but that may not be crucial if I am careful to keep it plugged in when I am not walking around with it. Also, with the latest Battery Management driver it appears to take a charge even when turned on (though I have no way to confirm that objectively).
I faced this problem too, It's because the Windows YOGA Book use different battery "fuel gauge" chip (bq27542) from Android Yoga book (bq27514). only thing to do is to swap the battery fuel gauge + protection PCB from one to another. I've made video about doing it here
I now have two Android batteries and the defunct Windows battery. I am ready to try moving the Windows battery controller PCB to one of the Android batteries, but I am having trouble following your video. Do you have a slowed-down version, or could you describe what you are doing? Thanks.

This is quite complicated. I'll try my best to explain everything including the small details.
Tools
- Flat head screwdriver (for prying battery taps)
- Soldering iron, solder lead and flux (for soldering everything back)
- Multimeter (for checking the battery polarity)
First thing you need to do is to remove the protective masking tape that protect the battery taps. The use you multimeter to check the polarity of each battery cell (don't forget to use some marker pen to mark the polarity). Next use flat head screwdriver to pry off all of the welded-taps until they all came free from the board, do the same thing with both Android and Windows battery. Then swap the battery cells. Before solder the battery taps back to the board. You need to make sure that when you plugged the battery board back to motherboard ,the battery is aligned with the board and the flat flex cable is lay flat like original battery does. IIRC the battery isn't align properly (maybe off by couple millimeter). You may need some thick wire to connect the battery to the battery board. After everything was set. Make sure that the battrry polarity is correct (iirc the battery of android version is flipped compare to windows version) and carefully solder the battery back to the board. After everythingwas done. Use multimeter to check the batter voltage again to make sure that there's no short circuit that cause voltage to drops. The put the protective masking tape back, put itbback the the Yoga book. Do not put on the keyboard yet then connect the charger and power it on. Let it charge up for a moment and drain it once. If you sure that nothing is off, you can later put the keyboard back in place.
That helps. What did you do with the two sets of black leads from the Windows batteries to the PCB? Do the Android battery packs not include those connections?

Sorry for a late reply.
Those things are battery thermal sensor. I just place it as close as possible to the battery.
