We all know that if you continually don’t drain a NiCad battery down fully before you recharge it, it will form a “memory” and will only discharge down to that point in future use.
Now, do rechargable lithium ion batteries have this same effect? My brandy-new cell phone has a litium ion battery, and I’m not too keen on recharging it every 2 nights when the battery still has 1/3 of its charge left. I also don’t want to toss a $60 battery trying to find out.

Nobody ever calls me after they’ve done something smart.
Lithium ion batteries don’t have the memory effect but then again modern NiCd batteries don’t either. Overcharging NiCd batteries can cause a problem that is often misidentified as memory effect. Here’s some info on that. http://www.batteriesplus.com/techctn.html
FWIW I have a Qualcom phone, Sony Handycam and H-P laptop all with lithium batteries. I’ve never bothered with intentionally discharging the batteries and have never seen a problem with battery life.

Probably thinking NiMH batteries, which have a memory effect. Lith batteries last twice as long, don’t have memories (well, they do, but hardly noticable), and cost much more.

There’s a million fine looking women in the world, dude, but not all of them will bring you lasagna at work. Most just cheat on you.
I don’t believe in the “memory effect,” whatever its real technical details are.
I bought a phone four years ago, and I followed the rules (discharge completely before recharging and so forth), and within a year, it still would not hold a charge for more than 6 hours (it was supposed to have a 24 hour standby charge).
I have not had this problem with the lithium batteries. They have held up nicely.
