PRS 650 Battery Life

Sleep Mode is activated by just flicking the top slide switch - the screen then displays a picture and text to say how to get out of Sleep Mode (by flicking the switch again). This is customisable so you can have it set so that you just have a blank screen in sleep mode.

To power the reader down completely, slide and hold the switch for approx 3 seconds and you will be prompted whether you wish to power down the reader or not. Tapping the 'Yes' button on the screen will then cause the reader to power down completely (and therefor enot draw any power from the battery).

I am currently powering down in between reading from it and an still on full charge (4 battery bars) after 4 days. So it does look like even in Sleep Mode the battery is being drained.

Hope this helps. I'm thinking of just powering down completely overnight and leaving the reader in sleep mode during the day when I want to read. That way I should get a much better battery life.

UPDATE (28/04/2011) : Since this post I've been powering down my reader overnight and in-between reading, although leaving it just in sleep mode during the daytime if it's a day when I'm off work and able to read every now and then. This has made a dramatic improvement to battery life. I'm still on 3 bars after about 4 weeks of doing this. So it looks like if you want an extended battery life between charges that you need to power down the device overnight - after all, why leave it in sleep (standby) mode overnight for 12 hours when you're not going to be using it? I'm also not sure whether the battery performance improves after a few cycles of charging - it almost seems that I'm getting better performance now after only a couple of charge cycles.

PRS 650 Battery Life

I have been keeping the reader in sleep mode - and the charge only lasts as stated in my post. Switching it off completely seems to keep the charge for longer - as you would expect, so the battery is holding a charge so it seems that even in sleep mode the charge is being drained.

Could this be a software problem - perhaps the reader is not going into sleep mode correctly? The sleep mode screen shows up ok.

Runtime of PRS 600 on a Single Charge

Just started to test my PRS 650 - the claims are for 2 weeks between charges, but I'm lucky to get 1 week. I leave it on standby and after only about 2 days and at most 100 page turns it has gone down to half charge. I'm using the Sony mains charger rather than the PC's USB to charge it, maybe it will get better after a few charge/discharge cycles? Powering it down completely overnight it hasn't lost any power (as you would expect) so the battery looks to be holding a charge. Might try a reset next if things don't improve.

PRS 650 Battery Life

I have just got a new PRS 650 reader and finding that its battery life is rather short - I'm finding that it goes down to about half charge from full in roughly 2 days. I'm charging it from a Sony mains charger and it seems to reach full charge after about a couple of hours at most.

Whilst not reading I leave it on standby, which shouldn't take much power from what I've read.

Does anyone think I've got a faulty battery / reader or is this about the battery life people are getting?

PRS-350 battery discharging quickly and hard to recharge

I have a PRS-650 and have found that it will not charge with a lot of micro-USB chargers - I read somewhere that a couple of the USB pins need to be shorted out to get the reader to accept the charge. Connecting it to a PC works to charge it, otherwise you will need to get the Sony mains charger (which charges it in about 2 hours from flat to fully charged).

I'm just going through some timings now as my reader is taking a full charge but has just lost half its charge after only 2 days - most of the time on standby and only around 100 page turns. Reading a lot of forums it seems that some people are having problems - so perhaps Sony have an issue with charging and/or batteries on these devices?
