Is it bad to charge your phone from 90 to 100?

Battery Health: Understanding the Optimal Charging Range

Maintaining optimal battery health is crucial for extending the lifespan of your smartphone or other electronic devices. One important aspect to consider is the charging range. While it may seem convenient to charge your phone from 90% to 100%, this practice can actually be detrimental to battery health.

Avoid Extreme Charging Levels

Batteries are most susceptible to damage at extreme charging levels. Regularly charging your phone between 90-100% or letting it deplete below 20% puts undue stress on the battery. This can cause the battery to deteriorate faster, reducing its capacity and shortening its lifespan.

Optimal Charging Range: 20-30% to 80-90%

Instead of charging between extreme levels, it’s recommended to maintain a charging range between 20-30% and 80-90%. This range minimizes stress on the battery cells, allowing them to retain their capacity for a longer period of time.

Charging Frequency

The optimal charging frequency varies depending on individual usage patterns. Some people may need to charge their phones multiple times a day, while others may only need to charge once every few days. It’s better to charge your phone more frequently with shorter charges than to allow it to fully deplete.

Trickle Charging vs. Extreme Depletions

Consistent trickle charging, where you recharge your phone throughout the day as needed, is better for battery health than allowing it to completely deplete. Extreme depletions can damage the battery’s ability to hold a charge, while trickle charging helps maintain a stable battery level.

Conclusion

Optimizing battery health involves avoiding both extreme charging levels and extreme depletions. Maintaining a charging range between 20-30% and 80-90% and consistently charging your device without letting it fully deplete will extend the lifespan of your battery and ensure optimal performance for years to come.
