There are a lot of misconceptions when it comes to batteries and extending their life, and a lot of it is hold overs for the old nicad days. I am not going to sit here and explain it all,but heres a link to a very informative site
Welcome to Battery University
Lithium Ion batteries in today's phones are very durable and dont require the care the old nicads do, if you didnt charge it for 24 hours you will be fine, I am one of those people who are much to impatient for that and I always get full expected battery life or longer (I have a 4 year old razor that lasts nearly as long as it did when it was new, and a 2 year old voyager that still gives excellent battery life)
One major difference I feel I should point out between nicads and lithium batteries( in case most of you dont feel like reading the site) is that while on older nicad batteries it was reccomended, and you really should have, completely drained the battery before charging them because they developed a "memory" and if you did constant partial charges you would recieve less and less battery life because of this "memory". However the exact opposite is true of lithium batteries, it is best to do constant partial charges and to keep the battery above 40% if at all possible as full and complete discharges of lithium ion batteries can actually shorten there life.
Hope that made sense, I been drinking a bit HAH.

P.P.S. the site is very useful I suggest you read it if you are a geek like me or want to better understand battery life
