What causes my phone s battery to drain quickly?

The reason for the power consumption is generally the battery capacity.

Due to screen display, application operation, communication connection, etc., the power consumption is also different in different usage states.

If you are using a Huawei phone.

It can be optimized in the following ways.

Battery life:

1.Use one-click power saving or one-click optimization to automatically diagnose optimization.

EMUI and below versions: Go to Settings > Battery, click One Click to Save Power, the system will automatically help you find some functions that may cause power consumption, and you can manually select optimization.

EMUI OS: Go to Phone Manager.

Apply, click One-Click Optimize, and optimize the settings that can save power according to the results.

2.Click on the power consumption ranking to see the apps with high battery consumption

Go to Settings > Battery > Power Consumption Ranking to see which software consumes a lot of power, such as the clickable app that you don't need to use for the time being and end the run.

3.Turn on Smart Resolution to help save power.

Follow the prompts to enter the screen resolution setting interface and select Smart or Smart Resolution.

4.Turn on the power saving mode.

Go to Settings > Battery and turn on the power saving mode to reduce the power consumption of your phone.

What are the reasons why your phone drains battery fast.

1. The reason for the battery: the aging of the mobile phone battery leads to a decrease in the capacity of the mobile phone battery, and the symptom of the decline in capacity is that the battery is not very durable and consumes power quickly. If this is the reason, replace the battery.

2. Infrequently used app software: Infrequently used app software will occupy valuable system resources, and the background will be resident and consume power, so it is recommended to remove some infrequently used app software to save waste of system resources.

3. There is a bug in a certain APP software: Some Android software developers do not control the program well during the development process, resulting in the mobile phone CPU being in a wake-up state all the time. A typical symptom is that when you check the power consumption information of your phone, you will find that the CPU power consumption is relatively high.

There are two reasons why the battery drains:

1. When the battery life is up, the standby time is significantly shortened (the normal standby is much worse than before, which means that the battery life is shortened and needs to be replaced).

There are two aspects, one is because the battery life of the mobile phone itself is poor, and the other is because the mobile phone battery has been excessively worn out to the point where it should be repaired.

It may be the reason for the aging of the battery, it is recommended to replace the battery, and the battery will be aged if the power is lost for a long time, or the battery will be used in low power.

1. There are too many background applications opened, if too many background applications are opened at one time and not closed, they will always run in the background and run out of power.

2. The screen is turned on too bright, the brightness of the mobile phone screen is one of the factors that consume power on the mobile phone, especially when looking at **, the screen is too bright and it is very power-consuming.

3. The mobile phone has turned on Bluetooth, WiFi, GPS and other functions that are not commonly used, so the mobile phone consumes power quickly, you can turn off these infrequently used functions, and then turn on these functions when you use them.

4. If the mobile phone itself is faulty and the battery is damaged, if the mobile phone fails and the battery is damaged, the mobile phone will consume power quickly, and it can not even be charged.

There are usually a few points of general power consumption:

1.The blue buds are always open.

2.Poor battery quality.

3.The battery is old.

4.Creepage. 5.The screen has been on for too long or there is a problem.

6.Playing or receiving** in a place with poor reception consumes power.

2.Open [Settings] on the page, swipe down to select [Battery], click [Power Saving Mode], and turn on the [Power Saving Mode] button to reduce power consumption.

3.Open the [Intelligent Power Consumption Protection] button on the [Battery] page, which can also fix the situation that the mobile phone consumes power quickly, and charge the mobile phone when the mobile phone is about to run out of power to protect the mobile phone battery;

Hope it helps.

6.Reduce backlight time.

7.Turn down the brightness of the display.

8.If possible, try to replace the original battery of the mobile phone.

3. Some Android software developers do not control the program well during the development process, resulting in the mobile phone CPU being awakened all the time.
