There are a number of reasons why iphones can lose power when they are on standby. Here are some tips to help you diagnose and resolve the problem:
< br >
1. Active background applications: Some applications run in the background, which may consume power. Close unwanted applications to reduce background resource consumption. You can use the \"Settings\" of iOS. \"General Purpose\" > Background Application Refresh to manage background application refresh.
< br >
2. Notifications: Too many notifications may cause the phone to wake up frequently and consume battery. Check your iOS Settings to turn off unwanted notifications. You can click on \"Settings\" > Manage in Notification.
< br >
3. Location services: Even if the phone is in standby state, location services may continue to work, thus consuming power. Turn off unwanted location services or set them to be available only for the duration of use. You can click on \"Settings\" > \"Privacy\" > Manage in Location Services.
< br >
4. Wireless LAN\/Bluetooth: Wireless LAN and Bluetooth may also continue to search for nearby devices when standby. Turn off these functions to reduce power consumption. You can click on \"Settings\" > \"Wlan\" or \"Settings\" > Manage in Bluetooth.
< br >
5. Low Battery Mode: If your phone is low on battery, low battery mode may turn off some background apps and functions to extend battery life. In low power mode, standby power consumption may increase.
< br >
6. System Update: If your iOS system has a new update, make sure your phone is updated to the latest version. New versions of iOS may include features that optimize battery usage.
< br >
7. Battery health issues: Aging batteries may cause faster power consumption during standby. If your phone has been used for a long time, check the battery health. If the battery health is below 80%, it may need to be replaced.

If you have tried the above suggestions and the battery life problem is still unresolved, it is recommended that you contact Apple customer service for professional technical support.
1. Background programs run too much
Friends who have played with Apple mobile phones should have this habit, open an app to play for a while, to open other apps, directly press the \"home\" button or slide back to the home screen, and then go to open another app. At this time, the app just opened is not actually turned off, but the background continues to run
2, mobile phone positioning, Bluetooth function
When some programs run, they need the support of mobile phone GPS and Bluetooth functions, so generally these two functions will be opened, and these two functions are also very power-consuming. Even in the standby state, these two functions are in the power consumption, so it will feel that the standby power consumption is fast.
3. Battery aging
If the battery ages, it will also accelerate the battery consumption. The general lithium battery is used for a long time, and the chemical substances inside will naturally consume, which will reduce the overall health of the battery. The lower the health, the faster the battery will drain. That is what we call excessive virtual electricity in our daily life.
for the following reasons
1, the aging of the battery itself, the machine has been used for more than a year and a half, this time the life of the battery will be lost, the specific amount depends on the usual use habits.
2, the system operation failure, opened a lot of apps in a short time, frequently switched background, background refresh too much, etc., the system appeared wind, did not react temporarily, resulting in heat and power loss fast.
There are many reasons for this, the most direct reason is that the battery is used for too long, battery aging if you exclude this factor, it may also be a system problem, there may be too many programs you open, such as positioning, Bluetooth, background running app
