Why Replace Your Galaxy S21 Battery?
The Galaxy S21 uses a compact 4000mAh battery that degrades faster due to 5G usage, fast charging, and heat exposure. Common signs indicating replacement is needed include:
– Battery percentage dropping erratically from 30% to 0%.
– Visible swelling pushing against the back glass panel.
– Device overheating during normal use or wireless charging.
– Failure to hold charge beyond 4-5 hours of active use.

Using counterfeit batteries can damage the motherboard or cause safety hazards. Choosing an authentic Samsung Galaxy S21 Battery from MS Phone Lab ensures safe and reliable operation.
