How to check how long your phone has been used

Query the usage time after the device is turned on: enter Settings - System Management More Settings - About the phone - Status information - Elapsed time, check the boot usage time (some models need to enter Settings - My Device - More Parameters - Elapsed Time View), the usage time will be reset to zero after the device is restarted.

Use time query after purchase: The first use time of the mobile phone and the total use time after purchase can not be directly checked, you can refer to the purchase time on the invoice, if the invoice has been lost, you can refer to the production date on the box.

First of all, we choose to tap to open the settings that come with the phone.

3.Then, after entering the relevant page, we click on About Phone.

4.Finally, among the many messages about the phone, we find the elapsed time, which is the time it takes to turn on the phone.

Extended Materials. There are three techniques to determine how much power is left in a phone's battery.

Voltage test method.

This method is relatively simple and is obtained by simply monitoring the voltage of the battery. However, the battery charge and voltage are not linear, so this test method is not accurate. Especially when the phone battery is less than 50%, this method is very inaccurate.

Battery modeling.

This method is to build a data table based on the discharge curve of the battery, and the data sheet will indicate the power value at different voltages, which can effectively improve the accuracy of the measurement. But it is not easy to get an accurate data sheet, because the relationship between voltage and power also involves factors such as battery temperature, self-discharge, aging, etc. Only by combining a number of factors to make corrections can a satisfactory measurement of the amount of electricity be obtained.

Coulomb counter. A current detection resistor is connected in series at the positive and negative poles of the battery, and when there is a current flowing through the resistance, the coulomb meter will produce an induction, and the current flowing through the battery can be calculated by detecting the induction, so it can accurately track the change of the battery's power, and the accuracy can reach 1%. is the most accurate method of battery level detection.

How to maintain your phone's battery to increase the use time of your phone.

1.The battery does not need to be charged for too long and can be removed when it is fully charged.

2.It is best to only use the charger that was originally supplied by the manufacturer when you purchased the machine.

3.The contacts of the battery do not come into contact with metal or oily fittings, and pay attention to moisture-proof.

4.Batteries should never be immersed in water or thrown into fire.

5.Do not place batteries near low- or high-temperature objects, such as refrigerators and stoves.

6.When handling batteries, use special facilities.

7.If you need to change the battery, please use only the same type of battery.

8.Battery life is calculated based on charge-discharge cycles.
