Below are some recommendations for Android phone battery charging use, to help extend the battery life. Of course, if your Android device's battery has already become unreliable, it is still recommended to spend a few dozen yuan to buy a Pinsheng battery.
1. Regardless of use, lithium batteries have a "shelf life" of 3 years, and after three years, they degrade quickly. Another factor is the full charge cycle, which I won't explain in detail here, but after about 400-500 cycles, the battery depletes rapidly. It's a matter of whether you'll reach 3 years first or reach the cycle count first.
2. Aside from low battery, lithium batteries are also vulnerable to overheating, especially when charging. If your phone case has poor heat dissipation and the phone heats up during charging, it's best to remove the case while charging.
3. Don't always wait until the battery is completely drained to recharge, as this accelerates wear. Lithium batteries degrade more when at low charge, and keeping the battery at 40%-60% for a long time can maximize its lifespan. For frequently used devices, this is not feasible. However, you can keep it at 100%, meaning charging often and not unplugging after charging finishes. It won't overcharge, and at this time, the phone uses power from the source directly, so the battery doesn't consume charge cycles, which helps extend its life. You only need to fully charge and discharge once a month; this is to calibrate the battery indicator.
4. Charging overnight has absolutely no harm, because you're not using it, so it doesn't generate heat.
5. Using the phone while it's plugged in after charging will not cause any damage to the battery because it is powered directly by the source. This reduces the number of charge cycles and actually helps extend battery life. Many people argue that their laptop was always plugged in but the battery died after a year. Laptops are different from phones; this situation is often caused by heat. Laptops with poor heat dissipation experience rapid battery degradation, even if unused. If you always play games while plugged in, high heat from the power supply might overheat the phone, which is bad. In short, as long as it doesn't overheat, there's no problem; you can keep it plugged in before leaving home.
6. It is okay to use the phone while charging. Some people say that using it while charging slows down the charge—does that mean the battery is discharging while charging?Actually, that's not the case. There are two circuits in the phone: one charges the battery and the other powers the device directly via AC. Slow charging occurs because part of the current is used to power the device, so the charging current is smaller. This is especially noticeable when charging via USB, since its current is inherently low. However, it's worth noting that slow charging with low current is actually preferred by lithium batteries, as it generates less heat and is better for their lifespan. Additionally, don't play games or use the phone under heavy load while charging! The reason isn't the large power consumption, but again, it generates considerable heat, which reduces battery life. Generally, browsing the internet or sending messages is fine, but holding it for long calls is not recommended—using earphones is suggested.
