How to Condition Your Cell Phone Battery
Conditioning a cell phone battery properly is a process that every purchaser of a new cell phone should follow. Too often, though, new cell phone owners do not follow a proper battery conditioning regimen, resulting in a bricked battery that cannot hold a charge. If you properly condition the battery, it should provide years of use.

1
Assemble your cell phone as directed. In nearly all cases, your cell phone battery will be partially charged to begin with. Do not plug in your cell phone right away, instead use it normally until the battery is completely discharged. (If you improperly charge your cell phone the first couple of times out, you can easily ruin the battery.)
-
2
Plug your cell phone, battery intact, into a wall charger. Do not charge your cell phone via USB or a car charger the first time out, as the voltage will not be the same. To condition a cell phone battery properly, use the original equipment charger with the proper voltage.

3
Use your cell phone as normal, now that it is fully charged. To condition a brand new cell phone, try not to use media or web-heavy functions straight off the bat that will drain the battery quickly. You want the battery to discharge the first few times at a slow, even rate.
-
4
Drain the battery fully before plugging the cell phone in. Do not fall into temptation to plug the cell phone in a second time before the battery is fully drained. While this will not damage your cell phone or battery during standard use, you need to properly condition the cell phone battery by draining it completely before plugging in.
-
5
Repeat the process four or five more times before even thinking about plugging in your cell phone when you still have battery power left. After completing proper cell phone battery conditioning, it will not hurt your cell phone battery to plug the cell phone in every night or to convenient power sources such as USB ports during the day. Conditioned cell phone batteries are meant to be able to catch a few minutes of charge as needed, but it is the first few days that are vital to good conditioning.
-
6
Continue to drain your cell phone battery completely before plugging it in at every available opportunity. Regardless of the age or conditioning of your cell phone battery, it will always last longer over time when discharged fully before charging again. Don't obsess over it to the point where it affects the way you use your phone; $35 for a new cell phone battery is not the end of the world.

Tips & Warnings
Some cell phone batteries are defective from the onset. If your cell phone's battery cannot hold a charge even with proper conditioning, contact your carrier. It will be replaced free of charge under warranty.
Always use a charger with the correct voltage rating. Even if the charger's connector is the same size, using a charger with too much power can damage your battery or cell phone.

barney512 is absolutely correct. The article is WRONG. One should never make a practice of completely draining lithium ion (LiOn) batteries, the batteries used in modern cell phones. -

If this information is not outdated and is actually correct, then why do cell phone manufacturers not provide the same information in instructions accompanying a new phone? -

I like Gislene's comments as well, but found your article rather fascinating. Thanks! -

First of all, the article did not explain why. This may have lead to many people assuming this article applies to the older NiCad or Ni-mh type. However, i beleive the reason for the conditioning is not for the actual battery (lithium ion polymer "3.7v"} but for the battery's built in computer chip which is hooked between the actual li-ion batt + - terminals and the outer terminals that we can see. If you do things with the battery that is not smooth drain at first use, the computer chip may not learn the battery correctly and may report a dead discharged battery prematurely with future charges. This may not be apparent until 6 or even 1 year later when the battery has had enough charge cycles for the effect to be noticeable. In other words, You are training the batterys computer chip to know how much the battery can discharge and to provide it too many charge discharge cycles... -

This is not good info for Lion batteries.Thia aticle would apply to NiCad and NiMH batteries which have a different charge algorithm than Lion. Lion batteries are best to maintain a charge and not to allow a complete discharge. I don't believe there are any cell phones now using NiCad or NiMH batteries. How old is this story?
