"10-20% per day charge loss (est)" - mine does not discharge nearly this much on it's own while powered off for a day. --Cheese 07:13, 26 June 2010 (MEST)

That was borrowed from some forum chat, it would be good to collect some numbers (see table below), both for going through a power cycle (chews battery on my phone) and powering up after 12/24/48 hours off. I also wonder if some batteries are more leaky than others. 50% loss over a weekend was (i think) quoted.--Tsh 19:43, 26 June 2010 (MEST)

Self-discharge

Off 13 hours = 100% -> 99%. (tsh)
Off 18 hours = 97% -> 97% (cheese)
Off 13 hours = 39% -> 44% (Ivanovic, FS#136)

Based on this, maybe taking a reading immediately after power on is not reliable, so I now suggest taking 2 readings, one immediately after power on, one 15 min later (after sitting idle) --Tsh 12:48, 5 July 2010 (MEST)

Charge times

Low power 1:36 17%->51% (->63% after 3 min not charging)(tsh)

All off (as low power state)

With WiFi off, screen off

500 MHz 4h10m 81%->63% (~23 hours battery life)
50 MHz 4 hours, 62% -> 45% (same as above)

So, Release1, Hotfix3, low power state only seems to shut off the radios, no other improvements.

MP3 only

500 MHz 63 min, 6% (17.5 hours)-exaile
500 MHz 2:54, 16% (18 hours) - ommpc
500 MHz 1:15, 7% (18 hours) - deadbeef
900 MHz 2:30, 15% (18 hours) - deadbeef
