Step 1: Check Battery Health

Go to Settings → Battery → Battery Health & Charging.

80-100%: Healthy battery
70-79%: Some degradation — expect slightly reduced life

Social media apps (Instagram, TikTok, Facebook) are top culprits
Games and video streaming drain battery quickly
Look for unfamiliar apps using excessive battery
