"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)

The total battery drain over the course of one week and one day, with a few minutes of usage on two occasions, was 6%. [1]

Charge times

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

Low power

"the CPU max speed is set to 14 MHz"

Is it still true ?--Linux-SWAT 00:37, 27 May 2011 (MEST)

All off (as low power state)

With WiFi off, screen off (Hotfix 3)

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

Hotfix 4 250 MHz, opp1 2:55, 10% (30 hours)

MP3 only

500 MHz 63 min, 6% (17.5 hours)-exaile
500 MHz 2:54, 16% (18 hours) - ommpc
500 MHz opp5 1:15, 7% (18 hours) - deadbeef
900 MHz opp5 2:30, 15% (18 hours) - deadbeef
250 MHz oop1 2:30, 15% (18 hours) - deadbeef

Standby and low power

I've demoted the 'Standby' charge time and put a 'no longer applicable?' tag after it. If it is still applicable, someone needs to document how we get into this standby mode.

One note of confusion, the linked comment suggests that in low power mode (LPM) the power LED is strong green, and it lasts in the order of 45 hours. Standby mode (SBP) is dim green and lasts over 150 hours. On my Ghz unit I get the dim green light when I push the switch to the right (which I've been calling low power mode) and it usually shows about 30 hours remaining, when I wake it with a reasonably full battery. The link still looks recent and good to me, but doesn't seem to tally with my experience. Levi (talk) 15:33, 2 May 2013 (CEST)

What about the power cable?
