Do you needto charge a new phone to 100 percent
In general, it's not necessary to charge a new phone to 100% for the first charge. In fact, it's recommended to charge it to a moderate level, such as 80-90%, to help the battery calibrate properly.
Here's why:
- Calibration: When you first charge a new phone, the battery management system (BMS) needs to learn how to accurately estimate the battery's capacity. Charging it to 100% can cause the BMS to overestimate the battery's capacity, leading to inaccurate battery life estimates and potentially causing the phone to shut down unexpectedly.
- Prevents overcharging: Charging a new phone to 100% can cause the battery to overheat, which can reduce its lifespan. By charging it to a moderate level, you can help prevent overcharging and reduce the risk of battery degradation.
- Helps maintain battery health: Charging a new phone to 100% can cause the battery to expand and contract excessively, which can lead to physical stress and potentially reduce its lifespan. By charging it to a moderate level, you can help reduce this stress and maintain the battery's health.
So, what's the best way to charge a new phone?
- Charge it to 80-90% for the first few charges to help the BMS calibrate.
- After the initial calibration, you can charge it to 100% if you need to.
- Try to keep the battery level between 20% and 80% as much as possible to help maintain its health.
Remember, it's always a good idea to follow the manufacturer's guidelines for charging and maintaining your phone's battery.
