"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)

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I've demoted the 'Standby' charge time and put a 'no longer applicable?'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?
