Is it just me? Or does A53 5g drains so fast because this phone has 5000mah battery capacity but it doesn't even last a whole day unlike my previous phone that has 4000mah. Is it because Samsung has a lot of bloatware or is it because of the new UI update?
Try not to use the phone too much.
Take it to a samsung service center. The battery might be defective. 5000 mah should last for more than a day
