These types of cell phone battery issues are also detectable and repairable by yourself

Have you noticed that the life span of cell phones nowadays seems to be shorter than before? The main reason is that the frequency of cell phone use has increased, and people no longer use their phones just to make calls and send text messages. And now that the cell phone battery is closed, it is still difficult to replace it yourself.

 

  So when is it that you don't need to change the battery and you can detect the solution yourself? When does the battery start to fail and do I need to replace it? This article mainly introduces the following three situations.

 

 

Cell phones can play for an hour with a 25% power loss; how about you?

 

 

1. The phone turned off the screen for an extended period or frequently lit up the screen. The power consumed by the bright screen of the phone accounts for more than 30% of the total power consumption of the phone. Therefore, it is recommended to shorten the screen off time (hibernation) in the phone settings to about 15-30 seconds and adjust the screen resolution to reduce the screen power consumption. At the same time, you can also turn on the power-saving mode. 2.

 

 

2. Do not turn off Bluetooth, WLAN, GPS, or other functions prematurely. These functions are needed for the phone to signal and receive work. If they are not turned off for a long time, they will always occupy the CPU, resulting in memory running all the time and reducing standby time.

 

 

3. memory-intensive software that runs for a long time. Games, videos, and other high-power-consuming applications cause the CPU to consume more power than usual. Before using this software, clear the background temporarily not in use, and properly reduce the screen brightness and media sound, which can be less power consumption.

 

 

4. The phone has been used for a long time, and the phone battery contacts have an oxidation phenomenon occurs. In this case, we can use a knife to scrape these impurities and wipe them with alcohol, which can reduce the resistance and extend the standby time.

 

 

5. Mobile phone battery aging is obvious, with fast power loss. A fast discharge indicates that the phone's battery capacity has shrunk and its life has become shorter. This time, the power is insufficient to change the battery.

 

 

What to do if the phone charging is getting slower and slower?

 

 

After using the phone for a while, I noticed that the charging time is increasing; what is going on? There are many reasons for slowing down the charging of cell phones, and the corresponding solutions are as follows.

 

the charging head or charging interface is blocked by some dust and other small dirty things. The solution is to clean the phone regularly. We can use a paper clip or toothpick and other small items, the charging head, headset hole for dust sweeping. If you are too lazy to sweep, it is best to bring a dust plug.

 

 

2. The charging plug or charging cable does not match the phone. In the case of the plug not having enough power, or a mismatched USB charging cable, because the support current is not the same, the voltage instability will also lead to slow charging of the phone. Its solution is to try to use the original phone charging plug or USB charging cable, a charging plug, and a charging cable that match.

 

 

3. If the battery contact point is faulty or oxidized, the battery information collected will be inaccurate. If the phone is used too long or lacks care, circuit detection problems will occur, and charging will also become slower. In this case, you need to go to the professional maintenance platform for repair.

 

 

4. The temperature of the charging environment is too high or too low. In a low-temperature environment, the low-temperature protection mechanism of the lithium battery will prompt the chemical reaction of substances that do not occur in the battery, resulting in the inability to charge or slow down the charging rate.

 

 

In a warmer environment, the lithium battery will be able to work well, but do not overheat, which will cause damage to the lithium battery.

 

The impact of other charging accessories, rather than battery aging, is what causes charging to slow down. But in turn, long-term charging too slow or poor contact may lead to battery damage.

 

 

What to do when the phone is hot while charging?

When the phone is charging, we frequently notice that both the charging head and the phone become hot. What is going on here? The following takes you, to analyze in detail.

 

  First, take a look at what causes the phone to get hot when charging. The phone charging current through the charging head and data line and other tools, you need to pass the phone power management chip for voltage reduction processing. This will produce a certain power consumption, and the energy generated by this power consumption will be released in the form of heat, which will cause the phone to get hot. General cell phone charging is inevitable and will produce a certain amount of heat. But the temperature is relatively low and is normal. When the phone is charging, it becomes hot and the temperature rises significantly, which is not normal.

 

  There may be several reasons for this.

 

The phone fell or was submerged in water, and the motherboard circuit short-circuits, causing false solder to leak.

 

It is also possible that the battery is poor quality or aging damage, and there is abnormal charging. This situation also requires timely detection and repair to professional maintenance stores to avoid explosions and other dangerous situations.

 

 

Solutions：

 

you can try physical cooling. Put the phone in a cool place such as the air outlet of the air conditioner to help lower the temperature

 

try to choose off charging, do not play while charging. This can effectively avoid charging, there are other programs to occupy the CPU, resulting in power consumption and thus causing the phone too hot. 3.

 

Remove the phone case for charging. The phone protective case will prevent the release of heat, and the phone charging and the motherboard's long-term overheating will cause circuit damage, which is very harmful to the phone. Note: When the phone is at normal room temperature, the heat does not exceed 50 ℃ is a normal phenomenon, when the phone temperature exceeds 50 ℃, it is recommended to immediately shut down and go to a professional repair store for battery testing.

 

 

In general, when the phone appears to have fast power consumption, slow charging, or abnormal heating, you need to start paying attention to the health of the phone battery. When the problem is not big, we can solve it by ourselves through the above methods. But if the problem is serious, it is still recommended that you go to a professional cell phone repair store for testing and repair, so as not to cause more damage and injury.
