Below are some Android phone battery charging usage suggestions for everyone, to help extend the battery life of your phone. Of course, if your Android device's battery has already become less durable, it is still recommended to spend a few dozen yuan to buy a Pisen battery.
1. Lithium batteries, whether used or not, have a “shelf life” of 3 years, after which they degrade quickly. Another factor is the full charge cycle, which I won't explain in detail here; after approximately 400-500 cycles, degradation accelerates. It depends on whether you reach 3 years first or the cycle count first.
2. Besides low battery levels, lithium batteries are also afraid of overheating, especially during charging. If your phone case has poor heat dissipation and the phone gets hot while charging, it's best to remove the case while charging.
3. Don't always wait until the battery is completely empty before charging, as this accelerates wear. Lithium batteries experience more degradation at low power levels. Keeping it at 40%-60% charge for the long term maximizes lifespan, but this is impossible for frequently used devices. However, you can keep it at 100%, meaning frequent charging without disconnecting immediately after finishing. It won't overcharge, and at this time, it uses power from the charger, so the battery won't waste charge cycles, which helps extend its life. You only need to fully charge and discharge it once a month to calibrate the battery indicator.
4. Charging overnight is completely harmless because you're not using the phone, so it doesn't generate heat.
5. Using the phone while it is plugged in after charging does not cause any battery damage because it is powered directly by the charger. This reduces the number of charge cycles and actually helps extend battery life. Many might argue: "My laptop is always plugged in, yet its battery died after a year." Laptops are different from phones; this is often due to heat. Laptops with poor heat dissipation see rapidly reduced battery life, even if unused. If you always play games while it's plugged in, the power supply may generate heat causing the phone to overheat, which is bad. In short, as long as it doesn't overheat, it's fine. You can keep it plugged in before going out.
6. You can use the phone while charging. Some people say using it while charging slows down the charge. Does the battery discharge while charging?Actually, that's not the case. There are two circuits in the phone: one for charging the battery and one for directly powering the device through AC. The reason charging is slow is that part of the current is being used to power the device, so the charging current is smaller. This is especially noticeable with USB charging, as its current is inherently small. However, it's worth noting that slow charging with low current is actually preferred by lithium batteries because it generates less heat, which is better for their lifespan. Additionally, do not play games or perform other heavy tasks while charging! The reason isn't high power consumption, but because, as mentioned, it generates a lot of heat, reducing battery life. Generally, browsing the internet or sending messages is fine, but holding the phone for long calls is not recommended; using a headset is advised.
