.:How to Make Your Cell Phone Battery Last Longer:.

Get the most out of your battery.
While many of us now use cell phones in place of land-line phones in our homes, the primary benefit of cell phones remains their portability. A cell phone is only as portable as its power source, however, so to get the most out of your phone you need to get the most out of your battery. When it comes to battery life, there are two separate, but connected, considerations: how to make the battery last longer between charges, and how to prolong the overall life of the battery.

Steps

Increase Time between Charges
Switch off the vibrate function on your phone, and use just the ringtone instead. The vibrate function uses up a lot of battery power. Keep the ringtone volume as low as possible if you get a lot of calls.


Turn off your phone's backlight. The backlight is what makes the phone easier to read in bright light or outside. However, the light also uses battery power. If you can get by without it, your battery will last longer. If you have to have the backlight, many phones will let you set the amount of time to leave the backlight on. Shorten that amount of time. Usually, one or two seconds will be sufficient. Some phones have an ambient light sensor, which can turn off the backlight in bright conditions and enable it in darker ones.

Turn off your phone's backlight when not in use. Turn the phone off. This is probably the most effective and simplest way of conserving your battery's power. If you don't plan on answering the phone while you're sleeping or after business hours, just turn it off. Do the same if you are in an area with no reception—such as a subway or remote area—or in a roaming area, since constantly searching for service depletes the battery fairly quickly. Some phones have an automatic power save feature, but it takes about 30 minutes with no service to kick in. By then, much battery power has been used.


Use the power save function if your phone has it. Avoid using the camera or connecting to the internet. If you know it will be a while before your phone's next charge, don't use your phone's handy supplementary functions. Flash photography especially can drain your battery quickly. If your phone has bluetooth capability, disable it when not in use.

Keep calls short. This is obvious, but how many times have you heard someone on their cell phone say, "I think my battery's dying," and then continue their conversation for several minutes. Sometimes, the dying battery is just an excuse to get off the phone (and a good one, at that), but if you really need to conserve the battery, limit your talk time.

Prolong the Life of Your Battery

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. You can also put it in a fridge for thirty minutes every now and again to make it last longer. You can do a similar thing using laptop batteries. Rember not to leave the battery in to long as it may cause the battery to function improperly.

Charge your battery correctly. Most newer cell phones have lithium-ion batteries, while older ones generally have nickel-based batteries. Read the label on the battery or the manual to determine which your is. If your cell phone has a nickel-based battery (either NiCd or NiMH), always charge your battery completely, and at least once every 3 weeks let it discharge completely (go dead) before recharging. Promptly remove the battery from its charger once the battery is fully charged. Lithium-ion batteries do not need to be completely discharged, and they work best with frequent partial charging. They are also unaffected by prolonged connection to the charger. Regardless of the battery type, use only a charger rated for your battery, and discontinue use of a charger that causes the battery to heat up excessively.

Store batteries properly. If your battery will be out of use for a while, disconnect it from the phone and store it in a cool place (the refrigerator is good, but the freezer is too cold). Do not store the battery with a full charge (40% charge is recommended), and recharge fully before using.

Clean the battery contacts on the battery and on the phone. Over time, the contacts may accumulate dirt. Clean them with a cotton swab and rubbing alcohol to maximize the efficiency of energy transfer.

Tips
Regardless of how well you care for your battery, it will die eventually. When it does, you may be able to have it refurbished by sending it to the manufacturer or bringing it back to the retailer. If it cannot be refurbished, or if you just want to get a new battery, be sure to recycle it, either by returning it to the manufacturer or retailer, or by bringing it to a recycling center.

Warnings
If you have a Lithium Ion battery, do not let it discharge fully! Many newer Lithium Ion batteries have a backup reserve so this never happens, but if a Li-Ion cell is completely discharged, it may never charge fully again.


Sometimes you have to use the phone's vibrate mode. Don't forget to switch back to a regular ring tone when you can.

Avoid cheap, knockoff chargers as they may cause excessive battery heating
When buying batteries, be aware that older batteries will have a reduced life. If you buy a battery at a clearance sale price, expect that you will get less life out of it. Do not dispose of old batteries in the trash. Batteries contain toxic metals, and electronic waste
from batteries and other electronic components is becoming a major problem.


Stay away from car chargers that advertise to charge the battery faster that normal. This will case an early battery life failure. Also, when using a car charger period, do not charge the battery when the inside temperature of your car is hot. Wait until the car has cooled before you plug in the phone.


In country area's place the cell phone where the signal is strongest as the phone is trying to seek the signal from your provider. The lower number of signal strength bars shown the faster the battery will discharge.
