1, the official factory is equipped with 5W slow charging, I believe most users will buy 18W fast charging head, which charges quickly, but it does great harm to the battery. According to my experience, the slower the charging speed, the smaller the battery loss! 5W is really too slow. It is suggested to replace the 10W ordinary charging head with 5V/2A.
2. Don't wait until there is no electricity to recharge. Lithium batteries are most afraid of overdischarge. If you often charge your mobile phone when there is almost no electricity, it will be very unfriendly to the battery. Long-term use will affect the battery life. Under normal circumstances, the battery can be charged at 5%- 10%.
3. Turn off animation and animation. One of the coolest features introduced in iOS 7 is called background motion. But if you move the iPhone and watch the application icon and the background image, you will see that they move independently of each other, as if they are on different planes. This is called parallax effect. This is really cool, but it will also drain the battery (and may cause car sickness). You may want to keep it to enjoy the effect, but if not, you can turn it off.
4. Don't charge it to 100%. The lithium battery has charging times, and it will cycle once every time it is charged to 100%. In the long run, the battery will wear out quickly, and the efficiency may only be 80% after one year of use. It is recommended to charge to 95% and unplug the power supply.
