    The most common problems with cell phone batteries</h2> </h2>

    Hi! I would not even ask you, if you have a cell phone or not. It’s like asking you: “Do you breathe?” Now, we could not imagine our life without a cell phone, it is used not only for communication, but for entertaining and for business purposes. But, there is one thing about cell phone, it should be with you wherever you go, that means, </p>

      How to define battery of what type does your cell phone have?</h2> </h2>

      It’s pretty simple. Most of the call phones have a removable back cover, so you can just take it out and read the battery type on its surface. Another way is to check you mobile phone’s manufacturer website. Find your model there and check specifications, you will find not only type of the battery, but some other important characteristics, such as capacity, for example.</p> </p>

      And the most modern way to check the battery type is to use a special app. There are many applications of this kind presented on the market, I am using Mugen Power App. It helps you to know the real picture of your mobile phone battery.</p> </p>

      It shows you historical data (%, mA, mW, mV and temperature) and calculates estimated run-times and battery aging, helps calibrate battery, and improves your battery run-time.</p> </p>
