XPS 9365 2in1 Battery problem

[Amharech Oussama]

Hi everyone, I just bought a used xps 9365, after charging it 100% and work with it, the battery shut from 60% to 4 % (the laptop shutdown by his own) that happens two days in a row, ( i instaled all new pilotes and bios) I checked with an app called batteryview and it gives me that my battery life is 66% and power time is between 1-2 in more than 80%, is that normal for a laptop that took at least 8 hours of work Please help.

If it is a used system, there is no telling what condition the battery is in.  You can open an administrative command prompt and type powercfg /batteryreport and it will give you some info.

Since the 9365 is a Modern Standby system, it will use some power while the system is in low power mode.  If you want to see that report, type powercfg /sleepstudy

Keep track of where each report is placed so you can copy it to the desktop to read, if necessary.

You might also run the command below just to see if the system is still in its original configuration or has been modified.

powercfg /a

There are other reports, just type powercfg /?

I will compare my two year old system with your reports but my system has not had heavy usage.

Thanks for your response, but what do you think about the fall of power from 60% to 7% in 1second‼️ yesterday it happens for the third time, is that normal,

I don't remember my system dropping that far that fast.  But it may be a problem of the info on the battery being updated to show the new number.

You say the battery was at 100% and was drained to 60% and then dropped to 4% quickly.  What were you doing and how long did it take to go from 100% to 60%?
