Smartphone batteries degrade over time, but the rate of degradation depends heavily on usage habits. A typical lithium‑ion battery in a modern phone is designed to retain up to 80% of its original capacity after 500 full charge cycles (roughly 1.5–2 years of daily use). By following these ten tips, you can slow down capacity loss and make each charge last longer.
1. Reduce Screen Brightness and Use Adaptive Brightness
The display is the single biggest power consumer. Setting brightness to around 50% can save 15–20% battery per day. Enable adaptive (auto‑)brightness so the phone adjusts to ambient light automatically. On an iPhone 12, go to Settings > Display & Brightness; on a Samsung Galaxy S22, find it in Settings > Display. For added protection, consider a quality screen protector – see our best screen protector brands guide.
2. Turn Off Unnecessary Connectivity Features
Bluetooth, Wi‑Fi, and GPS drain power when left on. Turn off Bluetooth when not using headphones or a smartwatch. Disable Wi‑Fi if you’re on a stable mobile network. Use location services only for apps that truly need them. On most phones, you can toggle these from the quick‑settings panel. For example, on an Oppo Find X5, swipe down twice to access the control centre.
3. Manage Background App Refresh
Apps refresh content in the background, consuming battery. On iPhones, go to Settings > General > Background App Refresh and disable it for apps that don’t need live updates (e.g., games, news readers). On Android, go to Settings > Apps > (app name) > Battery and set to “Restricted” or “Optimised”. This alone can add an extra hour of screen‑on time.
4. Use Dark Mode (on OLED Screens)
OLED displays turn off individual pixels to show black, so dark mode saves significant power. A 2020 study by Purdue University found that using dark mode at 100% brightness can reduce battery drain by up to 39%. Both iOS and Android offer system‑wide dark mode: Settings > Display & Brightness > Dark. This is especially effective on Samsung Galaxy S22 and Oppo Find X5 OLED panels.
5. Avoid Extreme Temperatures
Lithium‑ion batteries degrade fastest at high temperatures. Leaving your phone in a car on a 30°C day can permanently reduce capacity. Apple recommends keeping iPhones between 0° and 35°C (32°–95°F). Similarly, charging in a hot environment accelerates wear. If your phone feels warm during charging, remove the case. For water‑damage concerns, read our Samsung water damage repair article.
6. Optimise Charging Habits
Partial charges are better than full cycles. Keep the battery between 20% and 80% for daily use. Modern phones have optimised charging features: on iPhone, enable Settings > Battery > Battery Health & Charging > Optimised Battery Charging; on Samsung, use Settings > Battery and device care > Battery > Protect battery. This pauses charging at 85% when predicted to be plugged in overnight. For replacement options, see our guide to genuine iPhone batteries.
7. Disable Push Email and Reduce Fetch Frequency
Push email keeps a constant connection to the server. Switch to fetch every 30 minutes or manually. On iPhone, go to Settings > Mail > Accounts > Fetch New Data. On Android, open the Gmail app and adjust sync frequency. This can save 5–10% battery per day, especially with multiple accounts.
8. Turn Off Vibration and Haptic Feedback
Vibration motors consume more power than ringtones. Disable keyboard haptics and vibration for calls. On iPhone, go to Settings > Sounds & Haptics and toggle off “System Haptics”. On Samsung, go to Settings > Sounds and vibration > Vibration intensity and reduce it. This is a minor but cumulative saving.
9. Keep Software and Apps Updated
Manufacturers release updates that include battery optimisations. For example, iOS 17.4 improved battery life on iPhone 12/13. Android 14 introduced “battery‑saving” modes for background apps. Always install the latest updates. If you face software issues, check our Oppo software issues fix article.
10. Use Low Power Mode When Needed
Low Power Mode (iOS) or Power Saving Mode (Android) reduces performance, disables background activity, and lowers brightness. Activate it when battery drops below 20% to stretch the last few hours. On iPhone, you can set a shortcut to turn it on at a specific percentage. On Samsung, it’s in Settings > Battery and device care > Battery > Power saving.

Additional Hardware Considerations
If your battery health has dropped below 80% (check in iPhone Settings > Battery > Battery Health or use AccuBattery on Android), consider a replacement. For iPhones, Apple charges €89 for iPhone 12 battery replacement (as of 2025). Third‑party services like iRepair in Amsterdam offer lower prices. For Samsung, a Galaxy A52 battery replacement costs around €50. See our Samsung battery replacement A52 article for details.
Using a fast charger? Our fast chargers comparison shows that 18W–25W chargers are optimal for daily use – higher wattage (45W+) generates more heat and may accelerate degradation. Stick to reputable brands like Anker, Ugreen, or Samsung.
Conclusion
Implementing these tips can extend your battery’s lifespan by months, saving you the cost and hassle of an early replacement. Start with the easiest changes – reduce brightness, enable dark mode, and optimise charging – and you’ll notice a difference within days.
