How to Extend the Life of Your Phone Battery
Phone batteries don’t suddenly “go bad.”
They slowly wear out — a bit like running shoes or the patience of anyone who updates iOS on launch day.
But with a few simple habits, you can keep your battery healthier for much longer.
Keep Your Phone Cool
Heat is the number-one battery killer.
Leaving your phone in a hot car, under a pillow, or on the dashboard while using GPS cooks the battery and shortens its lifespan.
Cool battery = long battery life.
Avoid Letting It Drop to 0%
Fully draining your battery all the time stresses the cells.
Keeping it between 20–80% is far healthier.
Think of 0% like running your car on fumes — possible, but unwise.
Use Quality Charging Cables and Chargers
Cheap chargers don’t regulate current properly and can cause overheating or long-term damage.
A quality cable and the correct wattage charger go a long way toward preserving battery health.
Don’t Charge Overnight Every Night
Constant overnight charging keeps your battery at 100% for long periods, increasing wear.
If your phone supports it, switch on Optimised Charging so it finishes just before you wake up.
Turn Down the Screen Brightness
The display is the biggest battery drain.
Using maximum brightness all day is unnecessary and hard on both the battery and your eyes.
Automatic brightness helps a lot.
Close Power-Hungry Apps
Background apps like maps, social media, and trackers quietly consume battery.
Closing them once a day keeps things running smoothly.
Replace the Battery When It’s Time
Even with perfect care, batteries eventually wear out.
If your phone is draining quickly, shutting off early, or dropping percentages suddenly, it’s time for a replacement.
Most iPhone and Samsung battery replacements take around two hours and cost far less than upgrading.
