Why does the battery power of the mobile phone battery decrease after a period of time?

There is a quick and easy way to test battery life. First, we want to test to see if you have a battery drain problem. You can see the time statistics after the last full charge in Settings-General-Use, including use time and standby time. Use time refers to the time you actually use the device, and standby time is the sum of sleep time and device use time. Generally speaking, the use time should be much less than the standby time, unless you are not charging the phone all the time. Otherwise, your battery may have serious problems. The bottom line is that when the device is not charging, your usage data should be close to the actual usage time. Through a simple test, we can see that: record your use time and standby time, lock the screen to put the phone to sleep, talk for 5 minutes, and then turn on the phone, the standby time should be increased by 5 minutes, and the use time should not exceed 1 minute. If you add more time than 1 minute, it means that your mobile phone battery has been exhausted, you cannot sleep normally, and the battery life is greatly shortened. If your battery is okay, it's okay. But if you have a problem, try the following steps to significantly improve battery life. Although the first step seems very specific, it is very common and effective, and works well on multiple devices. IOS7 has a new background application refresh function, but you don’t want every application that supports it to refresh in real time. Therefore, turn off unnecessary background refresh to improve battery life. Of course, if it is not necessary, GPS and Bluetooth should also be turned off. After testing, Bluetooth power consumption is very high. It is interesting to close the application in ios7. Double-click the home button and slide to close the app. Many people think that closing the app can effectively save energy. Wrong! Even if you close the application, if you do this often, the battery life will be lower. When you close the app, you take it from your phone memory. You think, yes, this is what I want to do, but in fact, next time you open this app, it will reload. This process consumes much more energy than you think. In addition, IOS will automatically close some applications for you, because the phone needs more memory to run. You are doing something that the device does for you. In fact, except for music, location services, recording, and programs that allow background refresh, programs in the multitasking bar cannot run in the background. Functions running in the background will appear next to your battery icon. If the above two steps do not solve your problem, please try to cancel the real-time email collection. Set the receiving time to every hour, half an hour, or every 15 minutes to see if the battery life has improved. Although I know that receiving e-mail in real time is great, if it is not configured properly, it may cause a lot of damage to the battery. Especially when you have problems receiving emails on your mobile phone, the emails will always be received. In this case, the phone cannot sleep normally. The phone can be used for up to six hours, and the battery life is the same. Do you often use apps that push unnecessary notifications? Every time you receive a notification, your phone will wake up from sleep for 5 to 10 seconds, waiting for you to process it. Push notifications generally do not cause excessive battery usage, but if you have 50 apps, it may take 4 to 8 minutes. Therefore, turning off unnecessary notifications may affect the effect, but at least it will add new effects. Yes, you are right. Just turn off the battery percentage. Don't worry about your power. You can see the setting above the usage time item-General-Electricity. When I work at the Genius Bar, I noticed that many people are always checking the actual electricity consumption, such as obsessive-compulsive disorder. In fact, turning on the screen consumes a lot of energy. So, give up this obsessive habit. Don't always stare at your phone. There are many things in life that are more worthy of your care than a mobile phone, such as being with your family. An important reason why mobile phones consume so much power is poor signal reception. When the signal is not good, the device will try to find the signal, which will definitely increase power consumption. If you stay in a place with a weak signal, the battery life will be short. Even if the Wi-Fi signal is very strong, if the communication signal is very weak, your battery consumption will be very large, because the phone needs to find the SIM card, so you can make calls and send messages.
