How to calculate the standby time of the mobile phone battery

Standing, the signal is full, and the standby time is not used in the middle!

Take the Apple 7 phone, for example.

Procedure orange cautious.

1. At the beginning, find the application "Settings" icon on the desktop of the mobile phone first, and click to enter the operation interface of the new posture.

2. Then, after entering the operation interface of the settings, find the "Battery" option and click to enter the new operation interface.

3. After entering the operation interface of the battery, swipe up on the battery page to see the battery usage and standby time.

The battery standby time is generally 2-3 hours, a little better than 4 hours, if the new computer pays attention to the use of the battery will also have an impact on the battery use time, generally when using the power supply, it is best to remove the battery, so that the battery is good! Now the newly bought notebook comes with a battery of 4 6 cells, and the battery with a large capacity and a large number of cores needs to be explained in advance and purchased with additional money! With a period of time, you can adjust the deep charge and discharge once, the following values are for comparison only, and the battery should be subject to the actual battery life.

The standby time of a 4-cell battery is about 2 hours, the use time is about 1 hour, the standby time of a 6-cell battery is about 3 hours, the use time is about 2 hours, the standby time of an 8-cell battery is about 4 hours, the use time is about 3 hours, and the standby time of a 9-cell battery is about an hour, and it can be used for about an hour.

The process of checking the usage time of the mobile phone is as follows:

1. We first click on the settings option in the phone to enter the settings interface.

2. After that, click on the system options below to enter the relevant interface.

3. Then click on the About Phone option.

4. After that, click on the electronic three-pack voucher to enter the interface.

5. Here you can see the time that the phone has been used.

Common misunderstandings about mobile phone battery use:

1. The battery has a fixed number of charging times, so the charging should be recharged until it is used up.

As we all know, the mainstream mobile phone batteries are lithium batteries, and the way lithium batteries calculate their life is not by the number of charges, but by the number of battery cycles. The so-called battery cycle times are simply the number of times the user discharges the mobile phone 100%.

For example, if a user uses half of the power when it is fully charged, and when it is fully charged, it uses another half, for a total of 100% of the power used, which is counted as a cycle.

2. It takes 12 hours to fully charge the new phone before it can be used.

This is also a classic misconception, and the fathers said this to us from their experience. As for why lithium batteries don't need to do this now, it is because most of the previous mobile phones or electronic devices used nickel-cadmium batteries or nickel-metal hydride batteries, which often take a long time from production to sale to consumers, and the substances inside the battery need to be fully activated several times to achieve the best state.

Now the lithium battery of the mobile phone has been charged and discharged many times before leaving the factory to ensure its quality, and there is no need to activate it.

3. The mobile phone must be fully charged every time it is charged.

This is not actually a misunderstanding, but a small habit that every mobile phone user has. Looking at the phone charging to 100%, there is always a sense of satisfaction when the battery green bar in the upper right corner is topped up. But in fact, in the daily charging of mobile phones, it is the most scientific way to use them when they are charged to 80% and unplugged. <>

The capacity of the battery is 800mAh, if the difference is pure according to the 10-hour discharge capacity of 80mA, the new battery can be used for 10 hours. However, the amount of fibrillation is 180 mA, which is much greater than 80 mA, so the discharge time is approximately equal to 800 180 80% = hours.
