Best Tips on How to Increase Battery Life on Any Smartphone
Let’s go step by step. These methods are tested, safe, and work on both Android and iPhone.
Lower Screen Brightness to Increase Smartphone Battery Life
Your phone’s display is the biggest energy consumer. Keep brightness low or turn on auto-brightness to balance visibility and battery saving.
📖 Reference: Apple’s iPhone Battery and Performance Guide recommends lowering brightness for longer battery life.
Use Battery Saver Mode to Improve Battery Life
Every smartphone has a built-in Battery Saver or Low Power Mode. Turning it ON reduces background tasks and helps your phone last longer.

Turn Off GPS & Location Services to Save Battery
Apps like Google Maps, Uber, and social media use location all the time. Change settings to “While Using App” to save battery power.
Restrict Background Apps to Increase Smartphone Battery Backup
Some apps keep running even when you don’t use them. Go to Settings → Battery → App Usage and restrict heavy apps from running in the background.
Use Dark Mode for Longer Smartphone Battery Life
If your phone has an OLED or AMOLED display, turning on Dark Mode can give you 10–15% more battery backup.
📖 As per Samsung’s OLED Display Guide, Dark Mode reduces battery consumption on AMOLED screens.
Disable Auto-Sync & Push Notifications to Improve Battery Performance
Email, cloud, and social apps constantly sync in the background. Turn off auto-sync and refresh data manually when needed.
Update Software to Fix Smartphone Battery Drain
Brands regularly release updates with battery optimization fixes. Always keep your iPhone or Android updated.
📖 Check Apple iOS Updates or Android Security & Updates for details.
Uninstall Heavy Apps & Use Lite Versions to Increase Battery Life
Apps like Facebook, Snapchat, and Instagram drain more power. Use their lite versions or browser access for better battery life.
Turn Off Wi-Fi, Bluetooth & Mobile Data When Not Needed
Connectivity features keep searching for signals, draining power. Switch them OFF if you’re not using them.
Avoid Overnight Charging to Maintain Battery Health
Overcharging weakens your battery over time. Try charging between 20%–80% for best results.
📖 Battery University explains why partial charging is healthier for lithium-ion batteries.
Use Airplane Mode in Low-Signal Areas to Save Battery
Poor network makes your phone work harder, draining battery faster. Enable Airplane Mode in such areas.
Protect Your Phone from Extreme Temperatures to Improve Battery Life
Too much heat or cold damages the battery. Keep your phone in normal room temperature (20°C–35°C).
Use Original Charger & Cable for Safe Battery Charging
Cheap chargers can overheat and damage your phone. Always use original or certified chargers.
📖 Samsung Charging Safety Guidelines highlight why original accessories matter.
Enable Adaptive Battery Feature on Android Smartphones
Adaptive Battery uses AI-based optimization to limit apps you rarely use, extending battery life.
Replace Old Battery to Increase Smartphone Performance
If your phone is over 2–3 years old, the battery may be worn out. Replacing it will instantly improve backup.
