<![CDATA[Battery not being detected properly...]]>Ok so with this new tablet, the battery was fine in Android,

However in UT it is showing as 100%, but if I remove the power the tablet shuts down within 2 minutes. The green LED showing full charge is on.

After it shuts down, it won't start up again until the power cord is in long enough to have put some charge into the battery, then it sits at a flashing red LED, 5 minutes later the Lenovo splash screen appears, I then have to leave it for an hour before restarting the tablet and it boots into UT. Then the battery shows 100%!

This is on the OTA-23 stable install. My F tablet is also on the OTA Stable install, but doesn't exhibit this.

It is as though the battery is not being detected correctly. I would discharge the battery, but the second I pull the power, it shuts down, so I have no idea of telling what the charge state of the battery is!

Go back to Android and cycle through battery charging for a few weeks. If the battery is OK in Android, try UT again. I had null battery stats, but have not had time to put my Android tablet back on UT.

Yes, it is still an absolute mare to get running again from a flat battery.

same battery problems to my M10 / L .
Its a mb..f...x to get the tab to the startramp and boot.
Provided that a combination of ac supply in + power + vol up + down, in second of vibration turn off ac for 2sec, than put it back , after this treatment the fury starts sometimes.
Overcome this, to get it running there is only the ac supply, otherwise (and in some cases with ac) the tab quit its job because going out energy with a 100% full energy level 😉
uuuuuh what a freaky klump of hardware;)

So if anybody get some news ?? or workaround???

Happily nice evening

I will keep investigating...

I have managed to get hold of two more and kept on on Android and the other on UT. The two I have on UT show no battery stats, but work fine. One is the F version and one is the L version, so I am stumped at what was wrong with the one back on Android. When I get time I will put it back on UT and see what happens. I do often wonder if the hardware is slightly different....

No data on battery in the stats and shows battery fully charged at all time. Charging is very slow. In android no problem. Did you figure out where this error is coming from? Reported it in the gitlab.

That's what I was thinking. I will allow the tablet to charge and discharge under Android to kind of "calibrate" the battery. There are no marks on the case (not even scratches) to indicate the tablet has been split.
The redeeming feature of this device's Android is the distinct lack of bloatware, thank you Lenovo!

Yes, i understood the battery is fine on android, but like some oem screen panels are fine under android but not on UT, it could be the same.

It's kind of confusing that only your 605 has this issue, so that's why i ask about battery.

I don't want to split the device to check as it's another swine of a job.

If you're sure that is a genuine battery, then yes, you could rise an issue.

It was a mess around getting into COM port mode, but it has recovered and guess what, the battery is being picked up and is charging. This is something UT failed to do, the battery just stopped at 100%, when in reality was about 8% charged. Could this be worthwhile raising a bug report?

I have completely wiped and reinstalled UT on the release channel and it is still showing 100% and no discharge. It had crossed my mind that the battery could have been an OEM replacement. The battery monitor in UT settings shows 100% and nothing on the graph. I don't want to take it back to Android if I can help as that is a whole other mess to reinstall.
