Stop doing this: 6 ways you’re harming your iPhone battery without realising

Keeping your phone plugged in all night
Charging overnight seems convenient, but it keeps your battery at 100% for hours, which stresses it. Lithium-ion batteries prefer staying between 20% and 80%. Repeated overnight charging can slowly age your battery and reduce how long your phone lasts on a single charge.

Letting your battery hit 0% too often
Allowing your iPhone to die regularly isn’t good for its health. Deep discharges strain the battery and shorten its lifespan. It’s better to charge your phone before it completely switches off. Try keeping the battery above 20% whenever possible.

Using cheap or unverified chargers
A low-quality charger may save money, but it can damage your battery over time. These chargers don’t regulate power properly and can overheat the battery. Always use Apple-certified cables and adapters to ensure safe, steady charging.

Keeping brightness at maximum all the time
Turning your brightness up constantly drains your battery faster than you think. High brightness generates heat, and heat is the enemy of battery life. Use auto-brightness or reduce it manually — your battery and your eyes will thank you.

Leaving too many apps running in the background
Your iPhone manages apps well, but some apps still refresh in the background and eat up battery. Social media, maps and streaming apps are the biggest culprits. Turning off Background App Refresh for apps you don’t need can make your battery last much longer.

Exposing your phone to heat
Leaving your iPhone in a hot car, under direct sun or inside tight pockets during workouts can damage the battery permanently. Extreme heat reduces battery capacity and can cause unexpected shutdowns. Keep your phone cool and avoid using it heavily when it’s already warm.
