How to properly charge a smartphone, or a USB tester is needed for everyone

Does your smartphone take too long to charge? Does your battery last for less time than before? Does the device refuse to charge from a non-native charger? In all these cases, a USB tester will help.

Problems with the charge and chargers are the eternal companions of the modern gadget lover. Does it charge badly? Either the charging cord does not pass enough current, or the charger is unable to create the current of the required strength. And if they are quickly discharged? Either it was not charged enough due to the charger, or the battery is already of poor quality.

Unfortunately, it is rather difficult to identify the cause of the emerging problems by eye. In order not to get involved with the purchase of expensive devices, it is enough to purchase one of the many options for a Chinese USB tester.

A device the size of a regular flash drive will help identify the cause of the problems. A lot of information can appear on its screen depending on the model. In the simplest form - the current parameters of the current. More advanced models may have various functions: measuring capacity, testing chargers, analyzing the charging process. There are models that can disconnect some of the USB port pins and see what happens.

In addition, a huge number of chargers and USB-cords are not suitable for charging modern smartphones and tablets: they do not match in terms of current strength. The 1, 5–2 ampere required for many devices is provided by only a few, especially successful copies or products of trusted manufacturers (which are always counterfeited). This is where the tester comes in handy.

Working with the device is quite simple. On the Internet (and on your own charger), you can find the parameters necessary for the correct charging of the gadget. Then the cord is connected to the charger at one end, and to the tester at the other. And, of course, to the device under investigation. The battery charging process begins, during which the tester displays the parameters of interest to us: voltage and current. Thus, you can determine if these parameters are sufficient for fast and correct charging of the device.

If you charge a fully discharged smartphone or other gadget and at the same time keep track of the time, you can calculate the real capacity of the battery. (Some models of testers immediately indicate the charge passed through them in the required values.) This will allow you to tell exactly whether it is time to replace the battery.

Due to its small size and low price, such a device should be recommended not only to gadgets and geeks, but in general to all users of portable electronics. There will be no superfluous on the farm.

You can buy an advanced version of the tester, for example, here. In Russia, there is a fairly large selection of such devices in stores selling smart chargers, for example, here.
