Battery 0: Unknown, 83%
buscando información, he encontrado que este problema tbn se presenta en windows y se soluciona actualizando el driver, pero lamentablemente lenovo no da soporte para linux.
He probado actiualizando el kernel al 4.15.0-22 y con dist-upgrade pero el problema persiste, haciendo un test con el fwts obtengo el siguiente resultado:

Test 1 of 1: Battery test.
This test reports which (if any) batteries there are in the system. In addition,
for charging or discharging batteries, the test validates that the reported
'current capacity' properly increments/decrements in line with the charge
/discharge state. This test also stresses the battery state reporting codepath
in the ACPI BIOS, and any warnings given by the ACPI interpreter will be
reported.
Found 1 batteries.
Test battery 'BAT1'.
FAILED [HIGH] NoSCIInterrupts: Test 1, Did not detect any SCI interrupts.
FAILED [HIGH] NoGPEInterrupts: Test 1, Did not detect any GPE interrupts.
FAILED [HIGH] BatteryNoEvents: Test 1, Did not detect any ACPI battery events.
FAILED [MEDIUM] BatteryNotDischarging: Test 1, Battery BAT1 claims it is
discharging but no charge is used.
Got 10 interrupt(s) on GPE gpe13.
Got 141 SCI interrupt(s).
Got 141 interrupt(s) on GPE gpe17.
Got 151 interrupt(s) on GPE gpe_all.
PASSED: Test 1, Detected ACPI battery events.
FAILED [HIGH] BatteryNoEvents: Test 1, Could not detect ACPI events for battery
BAT1.
FAILED [MEDIUM] BatteryNotCharging: Test 1, Battery BAT1 claims it's charging
but no charge is added
Please ignore this error with a new battery
FAILED [LOW] BatteryZeroCycleCount: Test 1, System firmware may not support
