Battery drains too fast

If you left home with a full charge in the morning and the battery was already low by noon, this guide is for you. The usual culprits are screen brightness, background apps, or an aging battery — try these steps.

Steps

1. Lower the screen brightness
   A bright screen is the battery's biggest enemy. Open Settings > Display > Brightness and keep brightness below 50%, or turn on Adaptive Brightness.
2. Check battery usage
   Go to Settings > Battery > Battery Usage. If an app you barely use is eating the most battery, uninstall it or turn off its background activity.
3. Keep wireless features off when not needed
   Turn on Bluetooth, Wi-Fi hotspot and Location only when you need them. In Settings > Location, set the location permission to 'While Using' or 'Never' for apps that shouldn't have it.
4. Set screen timeout to 30 seconds
   Set Settings > Display > Screen Timeout to 30 seconds. A screen that never turns off drains the battery fast.
5. Use Battery Saver
   Turn on Battery Saver / Power Saving mode during the day (from the Quick Settings shade). With heavy use it can buy you 1–2 extra hours of battery.
6. Old battery? Check its health
   If your phone is 2–3 years old, its battery capacity may have dropped. Mobile Ustaad tip: get a battery health test at an authorized service center — avoid cheap roadside batteries.

Tips

• Social media apps running in the background eat the most battery — turn off their auto-start permissions.
• Leaving the phone plugged in after it reaches 100% is not good for battery health.
• Buy a certified-brand power bank instead of a cheap one — a fake power bank damages the battery.
