How to charge a smartphone!

I've read some conflicting information over the past few weeks, so here goes!

What's the best way to charge a smartphone if you're looking to get the most from each individual charge, and long term, to maintain the battery's life for as long as possible?

1. Should you always charge your phone to 100%? Does it matter if you don't?
2. Should you always let your phone battery go down to 0%?
3. Are partial charges through a laptop (say you're transferring content) ok?

Batteries are pretty much immune to different charging regimes these days, just do whatever's easiest. I charge my phone overnight, which means it spends hours on charge at 100% battery until I wake up, it's never appeared to cause any harm to any of my phones.

If 1) were an issue, most modern smartphone makers oughta be sued. They constantly need
to be hooked up to PCs for syncing this and updating that. Every time you connect it for such tasks, the device gets charged temporarily...

As to 2) You shouldn't. It's actually not good to do that too often.

3) => see 1)

In fact: I'm with matt on this one.
Chances are you won't keep your phone for more than 1 or 2 years. The battery is somebody else's problem thereafter :p

These days Li-ion batteries are rated for what, 1000 cycles? That's less than three years of using your phone all day and then charging it up at night, I think you'd struggle to kill it before its 1000 cycles were up with any charging habits. Beyond its 1000 cycles, its living on borrowed time and you should be expecting to replace it anyway.
