Windows 10: Battery report at 153%, different from system battery indicator, battery drain to 0%,...

I have the following issue: The laptop discharges during sleep down to 0%. This is below the 5% threshold at which it shuts down automatically when being used. In summary, the laptop drains much energy during sleep at night time.

To understand this, the following was done: 1) powercfg -batteryreport and 2) the admin rights sleepstudy.

1) batteryreport gives:

DESIGN CAPACITY
70,001 mWh
FULL CHARGE CAPACITY
63,489 mWh

But, at a 99% charge (indicated by the battery icon in the taskbar), this report indicates more than 100% charge, thus an inconsistency between batteryreport and system battery icon:

15:43:34
Report generated
Battery
147 %
62,527 mWh

2) The second sleepstudy report "correctly" (that is, same as the system icon) specifies the following:

15:17:57
0:00:16
Active
Drain
99%

What could be the cause for this inconsistency? Could thes be causing an abnormal shutdown where my laptop thinks it is above 0%, but then drains the battery until the end? Still, this would not answer why it drains so much energy during sleep. However, the latter question could anyway not be solved following so many instructions.

N.B.: Yes, updates all done, Bios latest version etc. ASUS Zenbook UX480FD, 2019 edition, new.

Battery report

Gabriela,

I have very precise records of when I swap over my batteries [because I run battery reports both before & after] and the moment of opening up the computer or changing the battery does not show up in my battery reports.
- My Battery report section Usage history - History of system usage on AC and battery goes all the way back to when the computer maker finished setting the computer up [and then posted it to me]. Your corresponding records seem to show the same.
- I know of no command to reset the parameters listed in a battery report.

The Start time entry you circled in red shows the time that the computer was turned on or awakened on battery power. There is no indication of anything dishonest being done. Windows re-starts that list whenever it feels like it. There is nothing significant in that entry at all. Just for example, my Battery report Start time entries are only showing for today but the computer was in use yesterday and earlier on battery.

Battery apps and battery report lack data

Below I have Copy / Pasted a report generated by the PC. As you can see (I hope) most of the expected battery data is simply not there. I have four Store apps monitoring the battery, two of which concentrate on displaying battery usage statistics in tables and graphs. But they also do not show the data. The battery is reported to have zero charge when in fact it has up to 100%. I have been frequently getting an annoying pop-up notification saying the battery has 0% charge and to 'connect the charger', when it is connected and charging. I have examined Settings and Tasks Library but have not found anything to explain this.

It is important to me to be able to monitor the battery in my 2-in-1 tablet

Battery report

Is this a normal check, or does it indicate a system change?
