How to charge an XDA battery for best results

wondered if people have an opinion on the best way to charge the XDA.

With my current mobile (samsung N500) I always used the policy of charge until full, then run until flat, then charge until full again etc.

ie, never recharging until it was flat. This is a bit of a throwback to when I used to use nicads a lot about 15 years ago.

the methodology being that if you did it this way the batteries remembered how much charge they were supposed to hold.

however, these new lithium polymer batteries in PDA's aren't supposed to have this issue are they?

On my samsung it's been fine, it's held charge well and never really gotten less, even after a years worth of charging and discharging.

A chap at work does the complete opposite, he puts his on charge whenever he can, whether it's flat or not, and usually before it falls below 80%, his reasoning being that he read somewhere that if you trickle charge it a lot it lasts longer.

as you can see, two conflicting methods of working.

what should I be doing to make my battery last as long and as well as possible

so I can charge it each night whether it's flat or not? sorry if this sounds dumb but I just want to make sure I understand this right,

don't fell like sending it off to have the battery replaced every few months because I abuse it.

well after one days use I'm impressed by the battery life

fully charged and went off charge at 5pm

10 mins talk time
3 hours farting around with it in the evening

went to bed at 11pm

backlight off
no switch off set
phone switched off

by 7.30 am this morning, still had 30% battery left

nice.

doesn't sound out of the ordinary.

playing of MP3's really drains the batteries. quite a few reviews use draining the batteries by playing MP3's as some sort of yardstick.

I've seen reviews that quote the XDa as running down flat after 3 .5 hours from playing MP3's.
