First you need to completely discharge the battery, i.e., to such an extent that the phone itself is turned off. Next, open the manual, find the Chapter on the first charge of the phone. Here will be listed what time this will take. After you connect the charger. A complete set of the energy capacity of the battery will take about ten to eighteen hours.
The phone can be left on charge over night. It is desirable to disable it to allow the battery a was focused only on the accumulation of energy, and not sharing it on the electronics device.
When the indicator shows that the battery is full, it means that over fast charge, then it continues slow. You should not keep the battery on charge for more than twenty-four hours to prevent over-accumulation of energy.
Similar procedure from full discharge to full charge you need to spend two or three times, then your phone will be ready to serve you more time even with large load and small temperature. In common parlance this process is called "training". However, it is only necessary for Nickel batteries, if you have lithium – does not require "training", it can be used in normal mode.
Nickel (NiMH – Nickel-metal hydride) batteries and later is recommended to put on charge subject to its complete absence. Systematic long charging (e.g. at night) may decrease its usable capacity.
Lithium-ion (Li-Ion) batteries, in contrast, implies prolonged charging. If the indicator showed the content, it means only recruited about eighty percent of the remaining twenty will be accumulated over the next two to three hours.
