Why smartphone is charging slowly and how to fix it

1. Stereotypedly charger

One of the most common reasons for the decline of the smartphone charging speed is banal change of the charging adapter. Perhaps you just use someone else's charger with enough high power output current.

Usually low-cost smartphones without the support of fast charging adapters have the original strength of the current from 1 to 2 A. Find out exactly as possible, looking at the fine print on the charger or in the characteristics smartphone.

Complete adapter recommended to replace accessory with identical power output current or higher. Even if you normally use the memory to 1 A, you can easily switch to the adapter with a current 2 A. But if you, on the contrary, with 2 A switched to 1 A - smartphone will charge much slower.

2. Damage to the USB-cable

If you change the adapter problem not solved, perhaps, the reason for reducing the charging rate lies in the USB-cable. Especially if he has some kind of mechanical damage: it could chew your pet or was coerced by the plug itself when bending.

The probability that this was the reason for the slow charge is quite low. Typically, mechanical damage is completely removed from the cable system, but still need to check. Simply replace the wire to any other.

3. Problems with connector

It is possible that the problem of low rate charging connector lies in a smartphone, which may eventually be subjected to corrosion or contamination simple. Make sure it is free of dust, and has no visible damage.

Remove fine dust particles from the port can be using a small brush or a toothpick. Use a needle or other metal objects should with great caution, as there is risk of damage jumper contacts.

4. High load device

Affect the charging rate can be high and the background of the smartphone activity. That's when the power is usually automatically downloaded and installed the latest version of the application, and antivirusFor example, start wool memory.

All these processes require energy input, and therefore, on a full charge will take more time than usual. Find out what programs are actively consume the charge, in the section, "The Battery" in your smartphone settings, or "Battery." Just close unnecessary, thereby reducing the load on the device resources.

5. Depreciation battery

Lithium-ion batteries, the most commonly used in smart phones, have their own life. Typically, it is limited to certain number of recharges, then the effective capacitance battery reduced. Along with this may slow down and the rate of recharging itself.

This problem is particularly relevant for devices that are actively used for 3-4 years. Although in the case of the flagships of supporting accelerated charging, the batteries the problem can begin as early as the second year.

The solution here would be the only battery replacement. In the case of do it yourself it will be difficult to nonremovable back cover. It is better to contact an authorized service center.

6. The planned reduction of the charging rate

Almost all of the technology fast charging using special controllers themselves vary power, reducing it when it reaches a certain percentage of the charge. That is why from 0 to 50%, some smart phones are charged for half an hour, and the second 50% of them require more an hour. This is done to slow down the process of degradation of the battery and prolong its life.

For the same purpose some technologies intelligent charging overnight specifically reduce feed rate to the minimum, providing 100% replenishing only the very morning. The presence of these options, you can check the device settings in the section, "The Battery".
