During the operation of a smartphone or tablet, quite often there is a need to buy new charging devices. The original charger can accidentally burn out, break or just get lost, and the user will have nothing left to buy a new charger. But not always at hand, a store with branded accessories for a specific model, moreover, a smartphone can simply be a rare model or even Chinese, to which even a simple cover, not to mention the charger, can be found to be found even a simple case. In this case, the purchase of “any other” is not suitable, since in the near future, after the old charger, the gadget itself will pass.
How to choose the correct charger for Android
On the market of mobile accessories, there is simply a tremendous amount of charges from a wide variety of manufacturers. Moreover, the bulk of them are unquestioning or rootless charges of Chinese manufacturers. The reason for this flutter of the market is as follows: first of all, a lower, in comparison with the originals, the price, secondly, for some reason it is generally accepted that the charger is a completely primitive thing that is simply impossible to do badly. But in reality, this is far from the case.
Most of Chinese -made charges have characteristics that do not correspond to the stated in the technical documentation. The use of the most inexpensive elements and the low quality of the factory assembly leads to the fact that the Chinese charger gives a lower current, in addition with significant interference. Charging a smartphone with such a device will take much more time than original, and the battery will fail long before its validity period. Such unpleasant moments as: severe heating of the device, breakdown of the controller from power and other problems associated with unstable voltage inside the device are also possible.
To choose a new charger, you should use a special Android app called ampere. Ampere will help choose a new charger for specific characteristics of the device, as well as check the quality of work existing. Ampere will give an indirect assessment of the quality of the charging device used, as well as a USB wire. As the data obtained for analysis, the application measures the discharge current and charge of the smartphone battery. If the smartphone or tablet is connected to the charging device that is suitable for it and through a working cable, then the losses in the charge will be minimal, and, accordingly, the charge current will be an order of magnitude higher.

Before using the application, it should be borne in mind that it works with the current of the smartphone battery, so the data obtained are approximate and depend on the number of launched programs at the time of measurement, as well as on the brightness of the display and other parameters that give the load on the battery of the device. The measurement process itself takes no more than 10 seconds, for which the application makes 50 requests to the corresponding smartphone sensors, and then excludes peak values and determines the average value. Even such an average measurement method will allow you to check the quality of the purchased or old charger and connecting cable.
Due to the need to have certain sensors for the application, Amperee will not be able to function on all Android devices. Before loading and installing the application, you should familiarize yourself with supported gadgets from the list on the application page in Google Play. The number of smartphone models produced, so even if the device model is absent in the list, the application can still be tested.
