Your phone’s battery life depends as much on settings and habits as on its capacity. The good news: a few changes can noticeably extend each charge and slow down long-term battery wear. These tips work on both Android and iPhone; exact menu names vary by model and software version.

Find out what is draining your battery
Open Settings > Battery to see which apps use the most power, both on screen and in the background. One misbehaving app is often responsible for most of the drain, and updating, restricting or uninstalling it can make a bigger difference than any other tip.
Display settings
1. Use adaptive brightness
The screen is usually the biggest consumer of power. Automatic brightness keeps it as dim as is comfortable for your surroundings.
2. Turn on dark mode
On phones with OLED displays, dark pixels use less power, so dark mode can extend screen-on time.
3. Shorten the screen timeout
Set the screen to turn off after 30 seconds to one minute of inactivity.
4. Consider the refresh rate
120 Hz looks smooth but costs battery. Adaptive refresh rate is a good compromise; switch to 60 Hz when you need maximum endurance.
Apps and background activity
5. Restrict background activity
Limit background refresh for apps that do not need it, such as games and shopping apps.
6. Review location permissions
Set location access to “While using the app” for most apps, and disable precise location where it is not needed.
7. Trim notifications
Every notification wakes the screen and radio. Turn off alerts for apps you do not need to hear from.
Connectivity
8. Prefer Wi-Fi over mobile data
A weak mobile signal forces the modem to work harder. Use Wi-Fi where available, and consider airplane mode in areas with no coverage.
9. Leave 5G on automatic
Most phones intelligently switch between 4G and 5G. If your area has patchy 5G, preferring 4G/LTE can save power.
Charging habits for long battery health
10. Avoid extreme heat
Heat is the biggest enemy of lithium-ion batteries. Do not leave your phone in a hot car or charge it under a pillow, and remove thick cases if it gets hot while fast charging.
11. Use optimized or limited charging
Many phones can pause at 80% or learn your routine to finish charging just before you wake up. Enable these features to reduce wear.
12. Use quality chargers
Use certified cables and chargers that match your phone’s charging standard. Cheap, uncertified chargers can charge slowly or generate extra heat.
When to replace the battery
Batteries naturally lose capacity over time. If battery health in settings is well below its original capacity, or the phone shuts down unexpectedly, a professional battery replacement can make an older phone feel new again for far less than a new device.
Frequently asked questions
Is it bad to charge my phone overnight?
Modern phones stop charging when full, and optimized charging features further reduce wear. Charging overnight is fine, ideally on a hard surface where the phone can stay cool.
Does closing apps save battery?
Usually not. Both Android and iOS manage suspended apps efficiently, and reopening an app from scratch can use more power. Restrict background activity for specific power-hungry apps instead.
