What should I do if Victoria's mobile phone charges slowly?

1. Vito's mobile phone charges slowly, and sometimes it doesn't even charge. How to solve it?

Reason:

1, a mobile phone with a large battery capacity takes a long time to charge.

The charging time can be calculated by a simple formula: charging time = coefficient (generally greater than 1)* battery capacity (mAh)/ charging current (mA). That is, when the charging current is constant, the larger the battery capacity, the longer the charging time; When the battery capacity is constant, the greater the charging current, the longer the charging time.

2. The charging specification of the power adapter affects the charging speed.

At present, most brands of mobile phones have 5V standard chargers, but manufacturers generally have different output currents according to different battery capacities. When charging a mobile phone, in order to ensure that the charging speed of the mobile phone is fast enough, you should try to choose the original charger or other brand chargers whose output current is not lower than the original standard.

3. Inferior data cable is the "killer" to slow down the charging time.

It is difficult for ordinary people to tell the difference of data lines from the appearance, so the amount of current provided by different data lines may be different under the condition of consistent interfaces. Many low-priced data cables look quite thick, but in fact, the inner core is very thin, or they have been replaced with pure copper and aluminum wires. In addition, there may be hidden dangers in the contact materials and welding of inferior data cable connectors, which will lead to increased resistance. The standard data line resistance should be 0.5 ohms, while the inferior line may reach 3~6 ohms, and the charging efficiency will naturally drop 6 times to 12 times.

4. Weather factors that are easily overlooked

Many people have this experience. In the cold winter, mobile phones often encounter the problem of not charging electricity. This may not be a problem with the mobile phone, but because the temperature is too low. Because most lithium batteries used in smart phones are equipped with low-temperature protection mechanism, low temperature causes lithium metal in lithium batteries to deposit and no longer react with substances, which leads to short circuit inside the battery. At this time, it will not be able to charge or the charging speed will be very slow. This problem can also occur when the temperature is too high.

5. Correct charging skills help to improve the charging rate.

Lithium battery protection will be started when the battery power is very low. At this time, the mobile phone can't be turned on, and there is no response at the beginning of charging, and the charging time will be longer. It takes a long time for the charged mobile phone to wake up the battery and turn off the protection function. So try not to wait until the battery is dead before thinking about charging.

Vito's mobile phone is slow to charge and fast to use.

Low temperature will affect the battery activity, resulting in slow charging.

If the ambient temperature is normal (0℃ to 45℃) and the charging is slow, it is suggested that you try the following operation methods: 1, use the original charger to charge, and check whether it takes a long time to fully charge when it is turned off; 2. If you only charge at startup, it is recommended to close all background programs before charging (drop-down menu, click one button to clean); 3. Try to change the power socket to charge; 4. After backing up important materials (contacts, multimedia files, etc.). ), restore the factory settings (Settings-More Systems-Restore the factory settings, please do not check "Clear Completely"). 5. If the charging is still slow, it should be a battery failure. It is recommended to replace the battery for testing.

If the problem still exists, please take the purchase invoice, warranty card and machine to the customer service center for testing, and a professional engineer will solve it for you.

4. What should I do if Vito's mobile phone charges slowly?

The following actions are recommended for slow charging of mobile phones: turn off the battery and charge it.

Change the charging position to eliminate the slow charging caused by intermittent contact with the socket. If conditions permit, replace the standby charger for testing, or send it for repair and inspection.

When charging, if the mobile phone is equipped with a third-party plug-in such as a charging doctor, it is recommended to test it after unloading. Check whether there are foreign objects in the charging interface of the mobile phone, such as liquid inlet and sundries, which leads to poor contact between the charging interface of the mobile phone and the charger and slow charging. If this is the case, it is recommended to send it for repair as soon as possible.

Back up mobile phone data (phone book, text messages, pictures, etc.). ) and restore the phone factory settings (enter phone settings-reset-restore factory settings). Solution: It is suggested to plug and unplug the data cable and power adapter again to eliminate the causes of poor contact.

It is suggested that the charging data cable can be replaced if possible, and the power adapter can be tried. If it can be improved after replacement, it can be inferred that the accessories are abnormal. If there are other batteries (if the mobile phone supports self-changing batteries), it is recommended to try to replace them, and the battery failure will not be ruled out.

If the problem can't be solved effectively, for your normal use in the future, it is recommended to take time to go to a nearby authorized maintenance station for specific inspection and treatment. .

5. What should I do if Vito's mobile phone suddenly fails to charge?

Generally speaking, charging failure may be caused by the following situations:

1. The charger is broken. There may be something wrong with the charger itself. Suggest replacing it.

2. Poor contact of charging interface. It may be that the charging interface of the mobile phone is blocked by foreign objects and cannot be charged. Try cleaning the charging interface.

3. The battery is broken. It may be that the battery of the mobile phone has been used for a long time, or it is damaged in other circumstances. It is recommended to take out the battery and charge it with a universal charger to see if it is damaged.

4. The mobile phone is broken, probably because the electric board of the mobile phone is broken. In this case, it is recommended to go to the local customer service center for inspection and maintenance.

6. Why is the charging of Vito t20l mobile phone so slow?

First, uninstall junk applications and release system resources.

A large number of junk applications are preset in the new mobile phone, which not only wastes CPU, but also increases power consumption, even steals traffic and disperses the notification bar, seriously affecting the experience. After getting root permission, it can be achieved with the help of a third-party mobile assistant. What if you don't have root privileges? In fact, for Android 4.0 or higher mobile phones, you can achieve your goal without root. Just go to System Settings → Applications → Select "All", then find the junk application and select "Disable"!

Second, rationally optimize the management of mobile phone storage and memory.

1, if nothing happens, don't kill the background process, thinking that this can speed up or save power for the mobile phone. Background caching process is a good optimization mechanism for Android. The purpose is to start the program faster next time. You have to end people every time, right? ?

The memory mentioned here refers to the storage memory of the mobile phone itself. Is it better to install the software in the fuselage memory or expand the memory card? Suggestions are: commonly used software can be installed in your own memory, and infrequent or large-scale games can be moved to an external memory card, which not only solves the problem of insufficient memory, but also takes care of the running speed of commonly used software!

Third, mobile phone antivirus and security protection software are indispensable.

Computers need to be protected by killing software, and the era of smart phones is also essential! Now there are a lot of malicious Android applications on the Internet, even virus Trojans, which have caused great hidden dangers to the security and privacy of our mobile phones.
