How can the mobile phone battery be used for half an hour just after it is fully charged

If this happens every time, the battery is close to being scrapped and needs to be renewed.

The mobile phone battery can only be used for half an hour, which is not normal, several possibilities:

1.The mobile phone itself leaks electricity and short-circuits.

2.The energy storage function of the battery is declining, and it is nearing the end of its life.

3.The protection monitoring circuit inside the lithium battery is faulty.

4.The charger is faulty and appears to be full of illusions.

It can be compared with a new battery. You can also go to the mobile phone repair point to check whether the mobile phone has a short circuit, if there is no problem with the mobile phone, try to change the battery.

There are two scenarios. First, it is caused by the leakage of your mobile phone. Second, the battery cells in the board of your mobile phone are no longer working. It is recommended that you go to a professional repair shop to check whether your phone is leaking.

There is a problem with the battery. I used to be like that. It's good to change the battery...

Plainly. It's just that there is a problem with the circuit board in the battery, there is a circuit protection function inside, I don't believe you can use the thin guide to short the rechargeable battery, (be careful of burns!) You will see the thin wire reddening and eventually burn out.

This does not happen on the board, which means that the circuit is protecting. There is also a tentative method, using a motor, a power board, to stop the rotation. If it's easy to protect, then there's something wrong with your board.

The phone is leaking. Or there is a problem with the battery.

The phone is generally fully charged in two to three hours.

It is best to charge the phone for about 2-3 hours, and the battery of most phones will be fully charged during this time. When the mobile phone battery is fully charged, there is no need to keep the mobile phone in the charging state, and the charging macro appliance should be unplugged in time, otherwise the charging time will cause damage to the battery after a long time.

There are many people who think that the first three charges of the mobile phone battery must be fully charged for more than 12 hours, in fact, this is wrong, the mobile phone uses a lithium battery, and this charging method is no longer applicable.

There are a few things you need to pay attention to when charging:

1.Try to upgrade your phone to the latest version, as new systems often include more advanced power-saving technologies.

2.Avoid charging in places where the ambient temperature is too high, otherwise the battery capacity may be permanently damaged.

3.Try to use the original charger or a qualified compatible product produced by a regular manufacturer for charging.

5.Try to avoid charging your phone while playing, and charging it after the battery is fully drained. <>

1. Reasons 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 capacity decline is that the battery is not very durable and consumes power quickly. If this is the reason, replace the battery.

Some Android software developers do not have good control over the program during the development process, resulting in the phone CPU being awake 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. Therefore, you can find the battery consumption information through the mobile phone and exclude the APP.

What's the matter with my phone being fully charged in half an hour, my phone being fully charged in half an hour, what is it and why?

It could be that the battery is broken. 1. The typical performance of the fast life of the lithium battery is: it is full as soon as it is charged, and it is not used as soon as it is used.

2. It can be judged by substitution. Borrow someone else's same battery to try it, if it is normal, it means that your own battery is broken. If it's still not normal, it's a short circuit and leakage somewhere on the phone.

Smartphones are more likely to short-circuit near the volume buttons. 3. Another way to judge is that the mobile phone is often very hot for no reason, that is, it is leaking. Because energy is conserved, electricity must be converted into other ways of energy.

The first is that the mobile phone battery has been used for a long time and has reached the expiration date, so it's time to replace it. Look at how many years you've been using your phone.

Second, there is no real fullness, which shows virtual electricity.
