To preserve the health of your phone's battery, it is recommended to avoid charging it to 100%, use fast charging sparingly, not let your battery die completely, and keep your phone cool. Charging your phone between 20% and 80% is considered optimal for preserving battery health.

Optimal Percentage for Charging Phone Battery to Preserve Health

When it comes to preserving the health of your phone's battery, there are a few key factors to consider. Here are some tips on how to charge your phone battery in a way that will help extend its lifespan:

Avoid Full Charges

One of the most important things you can do to preserve your phone's battery health is to avoid charging it to 100%. This is because when a lithium-ion battery is fully charged, it generates more heat and puts more strain on the battery cells. Over time, this can lead to a decrease in battery capacity and overall health.

Instead, try to keep your phone's battery charged between 20% and 80%. This range is considered optimal for preserving battery health, as it reduces the amount of stress placed on the battery cells during charging.

Use Fast Charging Sparingly

Fast charging can be convenient, but it also generates more heat than regular charging. If you use fast charging all the time, it can shorten the lifespan of your phone's battery. To preserve your battery's health, use fast charging only when you need a quick charge before heading out. Otherwise, stick with regular charging.

Don't Let Your Battery Die Completely

While it's not ideal to charge your phone to 100%, it's also not a good idea to let your battery die completely. When a lithium-ion battery is drained completely, it can cause damage to the battery cells and reduce their overall capacity. To prevent this, try to recharge your phone before the battery level drops below 20%.

Keep Your Phone Cool

High temperatures can also have a negative impact on your phone's battery health. To help prevent overheating, avoid leaving your phone in direct sunlight or in a hot car. Additionally, try not to play resource-intensive games or use other power-hungry apps while charging your phone, as this can generate even more heat.

In conclusion, by following these tips and keeping your phone's battery charged between 20% and 80%, using fast charging sparingly, avoiding complete discharges, and keeping your phone cool, you can help extend the lifespan of your phone's battery and preserve its overall health.
