Phone Battery

Like any other object, the battery ages, the spoils of not proper use and care needs. But you can keep it in good condition on their own ...
How should we understand the term "good condition"? Applied to the battery for the phone means a normal state of its main parameters: its real capacitance, resistance and self-discharge.
Capacity primarily affects the duration of the mobile phone as in not working condition, and in the mode of activity (conversation). Also depends on the efficiency of the internal resistance of the phone during a call or SMS. Self-discharge effect on the reduction of capacity over time.
How can I check these settings? The main sign of dramatically increasing the internal resistance of the battery is off the phone at the time of the call. Of course, with the proviso that the battery contacts are clean and he is not corrupt. In such cases, it seems to us that the charge to "green", included as a very short time he was off. And it happens that the phone is disconnected at the time of an outgoing call, although until the shutdown indicator showing one or even two notches. All these are signs of increased internal resistance. Alas, to assess its quantitative importance in the domestic environment to the mere mortal is not possible.
The essence of self-discharge is to reduce the capacity of the battery - how it occurs after prolonged use. To assess this unpleasant option will need the charger with the function of the discharge, a little patience and some not complex manipulations. To start the discharge the battery fully discharge and immediately. Note how long it takes for a full charge the phone. Then re-charge the battery and leave him alone about a day. The next day, after 24 hours, discharge the same battery charger and will determine how long it takes for the ego fully discharged, and then compare these two time intervals. Naturally, the duration of the second interval will be smaller, and the results to know what capacity your battery has lost a day. However, so you can evaluate the discharge the battery only nickel-cadmium and nickel metal hydride. But the discharge of lithium-ion can be assessed only after a month charge.
