Don't you just hate it when your mobile phone battery wont even last until you get home? How it goes flat every time you talk, use the camera, listen to a song or browse the internet? It really is very frustrating to have a weak battery that cannot hold much power to last a day with average activity. Reasons for a weak battery are the misuse of the battery and the lack of proper maintenance. The capacity of a mobile phone battery is measured by its standby time and talk time. It is measured in milli-amph hours (mAh). Rechargeable batteries have three main types, Nickel Cadmium (NiCd), Nickel Metal Hydride (NiMH), and Lithium Ion (LiIon). Lithium Ion (LiIon) batteries are what you find in most mobile phones and in order to preserve the battery you might want to follow these steps.

Memory effect will reduce the life of a battery. Modern Lithium-ion batteries do not suffer from memory effect, although it does occur in Nickel-Metal Hydride (NiMH) units when charged from levels other than 0% of battery capacity. If the (NiMH) unit was fully charged when initially at say 20% capacity, the resulting available capacity would only be 80% of the factory original. Of course every time you charged the battery, the total available capacity would reduce and eventually your mobile phone would prove to be increasingly useless. Nearly all new electronic devices are now powered by Lithium batteries. You should always condition your (NiMH) battery from new.
