Blackberry does not hold battery life

1. Initialize a new battery. New batteries should be fully charged before their first use to obtain maximum capacity. Nickel-based batteries should be charged for 16 hours initially and run through 2-4 full charge/full discharge cycles, while lithium ion batteries should be charged for about 5-6 hours. Ignore the phone telling you that the battery is full--this is normal but is not accurate if the battery is not initialized. #DO NOT fully discharge a lithium-ion battery! Unlike Ni-Cd batteries, lithium-ion batteries' life is shortened every time you fully discharge them. Instead, charge them when the battery meter shows one bar left. Lithium-ion batteries, like most rechargeable batteries have a set amount of chargers in them. 1. Keep the battery cool. Your battery will last longest if used near room temperature, and nothing wears on a battery like extended exposure to high temperatures. While you can¿t control the weather, you can avoid leaving your phone in a hot car or in direct sunlight, and you don¿t have to carry your phone in your pocket, where your body heat will raise its temperature. In addition, check the battery while it¿s charging. If it seems excessively hot, your charger may be malfunctioning. 2. Charge your battery correctly, in accordance with its type. Most new cell phones have lithium-ion batteries, while older ones generally have nickel-based batteries. Read the label on the back of the battery or in the technical specifications in the manual to determine which yours is. o Nickel-based batteries (either NiCd or NiMH) suffer from a phenomenon known as the "memory effect." If you charge the battery partially enough times, eventually the battery "forgets" that it can charge fully. A nickel-based battery suffering from memory effect can be reconditioned, which requires the battery to be completely discharged, then completely recharged (sometimes several times). The appropriate length of time between reconditioning varies. A good rule to follow for nickel-battery cell-phones is to discharge them completely once every two to three weeks, and only when you have a charger available. o Lithium ion batteries, on the other hand, do not suffer from the same memory effect. However, many devices that use lithium batteries have a battery meter, showing the user how much charge the battery has left. Starting with a battery's manufacture at the factory, lithium ions oxidize in the battery, shortening its life. After a certain amount of time, the battery exhibits slightly different electronic properties, which the device can only detect when the battery is discharged. This type of problem is known as a ¿virtual memory effect¿ and occurs when your battery meter can show a high charge, then suddenly drops to low charge when the battery is almost dead. Every thirty cumulative cycles, you should discharge lithium ion batteries until the phone gives a low battery warning, then recharge it. If you discharge lithium ion batteries to zero voltage, the internal safety circuit may open. In that case, a normal charger will be inadequate. Reconditioning ensures that the battery meter on a lithium ion cell phone is accurate (although it will not affect actual battery capacity). o Regardless of the battery type, use only a charger rated for your battery, and discontinues use of a charger that causes the battery to heat up excessively.
