Question 1

How do I check laptop battery health in Windows 11?

Accepted Answer

Run powercfg /batteryreport in Terminal to generate an HTML report with design capacity vs current full charge. Settings → System → Power & battery shows estimated runtime. SysOverlay displays battery percentage and charging state on the desktop HUD; Home Plus can track wear trends across family laptops.

Question 2

What are signs a laptop battery is failing?

Accepted Answer

Sudden shutdowns at moderate charge, runtime much shorter than when new, swelling case, or full-charge capacity well below design capacity in the battery report. Replace the battery or contact the manufacturer if under warranty — SysOverlay helps you notice declining capacity early but cannot repair hardware.

Question 3

Does SysOverlay drain the battery faster?

Accepted Answer

The HUD is lightweight and designed for always-on laptops. It reads existing system metrics — it is not a heavy background scanner. You can hide battery fields in Client settings if you prefer a minimal overlay.
