"nil point" would you say, for Sony?  |
I measured the current in standby mode after ~5 minutes it was "off". I don't know if there is a chance the Reader would go into a "low power mode" after some more time. I don't think so because the Reader is starting up just as fast after 1 minute of being "off" as it would after a week. So there is not a "hibernation" mode or anything. But I can't confirm this 100%.
Also if I calculate and look at my usage of the Reader then all makes sense to me know. I don't read a lot and since the Reader will loose it's charge in about 1 month it's not so strange I thought I had a bad battery.
So anyone wants to put their Reader down for a month and confirm? Volunteers? Helloooo....

Basically I had the same problem (usually I don't read fast) but it seems the 1 month limit is common to all PRS-500.
If this is not a physial battery limitation but firmware/software issue ('running OS' while being switched off, whatever it means exactly) then I wish Sony will do something about that. I would be more than happy to see still 4 bars after one month (with little reading) even with the increased time required to switch on ('booting OS'). Probably the best option would be to have a choice: 'hard switch off' (maximum energy save, longer start up) and 'normal switch off'. Unfortunately first Sony firmware update was far from perfect so I'm afraid they won't solve the battery problem anytime soon. |
That would be nice if you could choose, but I'm not sure if they are able to do it through the software.

That wouldn't work because after the reset the Reader reboots and all is back to normal. Holding the Reset button down would probably work. Toothpick anyone?
