How to Make Cell Phone Battery Last Longer

• Is your cell phone constantly running out of juice? You can make your cell phone battery last longer with a few easy tips. Here's how to keep your mobile phone battery from dying too early
• Instructions
• DRAIN THE POWER
• Some people know that draining a lithium battery will actually expand its shrinking capacity. Do it too often, however, and it has the opposite effect. Drain your battery complete (or as low as you can) every couple of weeks. DO NOT DRAIN TOO OFTEN
• DO NOT OVER DRAIN
• Lithium cell phone batteries have a back up power reserve when normal power has been drained. This power reserve is essential to keep the lithium battery functioning until it can be charged again. It is NOT to keep your cell phone running even when the power supply is drained
• When a lithium battery is drained and must revert to its reserve power, it runs the risk of dying completely. When you drain your battery, do not leave it uncharged for an extended period of time or you will drain the essential lithium power back up. Even when your phone is not in use, this reserve power is being consumed by the battery. The time a lithium battery can remain drained varies according to the quality of the battery, but it is generally a bad idea to leave a drained battery uncharged for more than a day. The sooner it is recharged, the better
• DON'T OVERCHARGE
• Lithium batteries should not be charged longer than necessary. This will cause damage to the battery as excessive charging causes the battery to overheat. Over time, you will experience a significant reduction in power capacity
• STOP SEARCHING
• When you are outside your phone's service area, you probably get a message that says "searching for signal." If you are outside your service area for any length of time, turn your phone off. The signal will not improve, and your phone will waste precious battery power constantly searching for a signal that does not exist
• SIMPLE RINGTONES
• Keeping ringtones simple will do a lot to extend the life of your battery. In fact, if you are able to hear and respond to simple beeping ringtones, it's a great way to keep the juice. Using a complicated or fancy ringtone really only wastes power and annoys the people you think you are impressing
• TURN OFF VIBRATE
• Vibrate is great feature when you are an in a place where ring tones are not appropriate. However, when your ringtone is activated, the vibrate function is generally not necessary. The Vibrate function is one of the most energy consuming tasks your cell phone performs as it requires the battery to power physical movement of parts
• NO GAMES
• Playing games on your computer is a serious waste of its energy. It must run a program and constantly interact with your commands. If longevity is more important to you than entertainment, avoid games
• TURN OFF ACCESSORIES
• When not using Blue Tooth, GPS, or internet, turn these functions off on your phone. Follow the instructions in the manual that came with your phone

How to Extend The Battery Life of Your Digital Product

• Today, the digital camera is being used more and more by the average person and the analog film camera is rarely used these days. The digital camera also has many more functions that are controlled electronically

Electronic Control Means Battery Power Consumption:

•  True, the older analog film cameras used batteries for a few camera functions which included the flash, motorized film advance and sometimes the electronic control of shutter speeds. The modern digital camera uses battery power for many functions including telephoto lens functions, the LCD viewer display and of course the flash. Some digital cameras will retract the lens to its home position after the photo session is done and the user is just viewing the photos that were shot. This is a great power saving feature. The user can incorporate some personal power saving procedures that can even double battery life of any given type of battery. Probably the simplest approach to saving battery power is to plan your photo session and try to preset the camera function settings in advance if this is at all possible. My personal battery saving approach is to shoot my photos using the "available light" method. Sometimes this creates slight movement of the image due to slower shutter speeds either auto or manual but the natural rendition of the image will far outweigh this shortcoming. Available light photography is a totally separate branch of this art

Using The Right Battery Type Is The Key To An Uninterrupted Photo Session:

• Many camera users do not realize that some batteries available will provide much greater use between recharge or replacement. Using Alkaline batteries are the last resort, though without question they are the least expensive. They should only be used as backup when either (NiMh) or (Li-Ion) run out of power and will give you the least amount of camera session use. The (Ni-Cd) can be used but they must be fully discharged before recharging because of their "memory effect". One must keep in mind that the (Li-ion) is the latest in battery technology and will deliver more energy after being fully charged than (Ni-Mh) technology. Both (Li-Ion) and (NiMh) batteries do not suffer the "memory effect" plagued by the older (Ni-Cd)
• As far as which to choose between Nickel Metal Halide and Lithium Ion is mostly a matter of cost. The Lithium Ion battery is more expensive than the Nickel Metal Halide battery. They both can be recharged before being fully discharged and do not suffer from "memory effect" characteristics which is a loss in the specified total capacity of a battery which is encountered every time the battery is recharged
• Today, the digital camera is being used more and more by the average person and the analog film camera is rarely used these days. The digital camera also has many more functions that are controlled electronically
