Lifetime of a Cellular Phone Battery

In the modern world people can not live without cell phones. We need to be aware about the types of batteries that are available for the cell phones. Each type of battery is different.

Initially, the nickel cadmium (Nacl) batteries were used. They were least expensive and hence affordable. The disadvantage was that it had to be fully discharged and recharged every time it was charged. It had also the ‘memory effect’. After this came the Nickel Metal Hydride (NiMH) batteries. They were also affordable and less prone to the ‘memory effect’. It had to be completely discharged and recharged after the twentieth cycle. The latest batteries are the Lithium Ion (Li-ion) batteries which are more expensive than the earlier models. They do not have to be discharged and recharged. They are not affected by the ‘memory effect’. After this came the Lithium Polymer batteries. This is the latest technology. Compared to the earlier models the lithium battery cell phones are lighter, sleeker and far superior.

The storage or capacity of the battery is said to be the talktime and standby time of the phone. This is said to be in milli-amp hours (mAh). The lifetime of a cell phone battery depends on how we handle the cell phone. There are certain rules to be followed. The cell phone batteries should not be overcharged, as it will damage the phone. The battery generally gets charged in about three to four hours. The cell phone should be kept mostly on ringtone mode than on vibration mode. The vibration mode will drain more of its battery. The light that we see when we switch on the phone (which goes off after a few seconds) should be set as low as possible. A digital phone has in the digital mode hundred to two hundred hours stand by time, while in the analog mode it is only thirty to fifty hours. This makes a great difference. So if you are in an analog area switch off your phone, as it is more strenuous on your battery.

Take good care of your phone. Do not hit it or throw it down, as it is harmful for the phone. The metal contacts between the battery and the phone should be clean. When removing the battery turn off the phone as it is good for the battery. Avoid exposure to sunlight. If the phone is left in the dashboard of the car it will unnecessarily drain the battery and the capacity of the battery will be reduced.

Cell phone batteries generally have a long life and are maintenance free. The batteries should not be kept with coins, keys or other metal objects that will short circuit the battery poles. When the batteries are not being used they should be taken out of the cellphone and kept uncharged in a cool, dry and dark place. If the cellphone does not work, it is best to take it to an authorized dealer. It is not good to disassemble a battery. When the phone is not used, the battery will automatically discharge itself, in a few months. Although original batteries and chargers are expensive, it is good to use them. They will make the batteries last longer.

Extreme temperatures affect batteries. Do not expose to heat or cold. So, do not leave them in sunlight. The lifetime of batteries is calculated in ‘cycles’. The general lifetime would be a minimum of about three hundred cycles. This might happen in a year or maximum two years. The efficiency will decrease and the batteries would have to be changed. So for batteries, there is really no standby time and talktime, it is the lifetime that is measured in ‘charge cycles’.
