Are there any common electrical faults o r parasitic drains in the Alsvin that cause the battery to discharge overnight?

Many owners complain about the battery dying after the car is parked for a day o r two. Could there be an issue with the ECU, infotainment, o r cabin lights?

Yes, there are confirmed drain points in many Pakistani Alsvins:

Infotainment head units stay powered in standby.

Cabin lights o r door sensors remain on due to faulty switches.

ECU and keyless entry systems draw current while parked.
Many users report overnight battery drain after 1–2 days of non-use. Diagnosis with a multimeter and clamp meter often shows 100–250 mA current draw, which is too high.
