Stop Charging Your Phone from 0% to 100%: It Destroys the Battery—Here’s What to Do

Many people believe it’s okay to charge their phone from 0% to 100% regularly, but this habit can actually reduce your battery’s lifespan over time. Most modern smartphones use lithium-ion batteries, which are sensitive to extreme charge levels.

Draining your phone completely to 0% puts stress on the battery, and charging it all the way to 100% does the same, especially when done often.

Batteries naturally degrade with time, but charging patterns can accelerate this. Instead of waiting for your phone to hit 0%, try to keep it between 20% and 80%. This “sweet spot” helps maintain battery health and extend its overall life. Frequent full charges or letting your phone die repeatedly causes the battery’s chemical composition to wear out faster, meaning you’ll need a replacement sooner.

Also, avoid overnight charging. Even though modern phones stop charging when full, the battery still gets minor recharges through the night, which adds heat and stress. If possible, charge your phone in short bursts throughout the day rather than in one long session. Small changes in your charging habits can significantly improve your battery’s longevity.
