cellphone battery

the answer is it doesnt matter, itll be a li ion or li poly so no memory effect.

Eh my SGS does weird stuff every now and again. You can look into wiping the battery stats if your battery life goes down the drain. 

Go buy the kit ebay with 2 batteries, a charger, screen protectors and a usb cable for $15.

Not entirely accurate. While Li ion batteries don't have the memory effect the the older NiCad batteries had, many Li ion battery packs have battery monitor chips, which are basically fuel gauges for the battery. Frequent recharges can actually reset the threshold for low battery warning. My wife did this to a brand new phone, by charging it every day, but by discharging and recharging the battery a few times it recovered, and lasted the life of the phone.

There's a web site called Battery U that has tons of great information about all types of batteries. Best practices for Li Ion batteries is to not let them get too low too often. The battery can be damaged if the volts/cell gets too low. Recharging at 25% or so will help prolong the life of the battery.

How to prolong lithium-based batteries

I think it differs device to device, my Sony Vaio for example reccmoends only charging to 80% capacity to prolong battery life. But in general I haven't ever had a problem with cell phone batteries, charge it up, let it drain, charge it up again, with the good battery life of todays cell phones I think you'll be into a new phone before you really start noticing negative effects but then again YMMV.

in any modern phone the charge controller will protect it from being over-discharged.

just charge it when it gets low.
