Healthy Phone Charging Habits: How to Keep Your Battery Strong

Avoid Charging to 100%

Many individuals believe that charging their phone all the way to 100% is excellent. In actuality, lithium-ion batteries, which power most cellphones, do not appreciate being fully charged or entirely depleted. The optimal battery level ranges from 20% to 80%. Charging to 100% on a frequent basis causes excessive stress on the battery cells, causing them to decay more quickly. Similarly, continually dropping your phone to 0% might decrease its life.

Do Not Leave It Plugged In Overnight

It is tempting to plug in your phone before bed and let it charge while you sleep. However, leaving your device connected for hours after it reaches full charge is not healthy for the battery. Modern smartphones have safety features to prevent overcharging, but the constant trickle charge to maintain 100% still generates heat. Over time, that heat can damage the battery and reduce its capacity. A better habit is to charge your phone earlier in the evening and unplug it before going to bed.
