If you're going to discuss the latest in Li development, please do so in a separate thread.
This thread is about the PW's battery, which is more than likely a regular Li-Ion battery; which usually decreases to 80% after the first year (approx), not after 3 years.

Current Li batteries (and thus the PW too) usually have ~60% left after 3 to 4 years.

I just got back from a 7 day cruise. The night before we left I charged up the PPW and turned on Flight Mode.

When I got home on Monday I checked the charge; still about 50%.

I was reading it probably two hours a day which is a lot more than I do at home. On Monday I read it for around 4hrs or so, given that I was stuck in an airport since 9am til our flight left at 2pm. And I continued to read on the flight.

It's now Thursday afternoon here and I've just put it on the charger, after it indicated somewhere below 50% on the battery symbol.

I think that I can live with that...

2 hours of reading for 7 days is 14 hours of reading. That's about half the time Amazon states, and seeing that your battery was at 50%, it seems it's right on the money.

Well, given that the PPW lasted me a week away without needing to charge it, (which was good as I left the micro USB cable at home), then I'm happy with it.

Does anyone know of a battery timer app for the Kindle? (I did a cursory forum search and didn't find anything, but then I may not have been using the best terms.)

The best IMHO is this one:

I'm not sure I know what a battery timer app is...

There is http://www.mobileread.com/forums/sho...5&postcount=11 which simply spits out a report of the current level and more importantly the Available Capacity, which will diminish over the lifetime of the device....

"Thumb in the air metrics":
K3 Avail Cap should be around 1200 I have one that has dipped to 709
DX about 1300
K4 I have runs at 817 mAh
K5 runs at 956 mAh
Don't have a PW to compare to sorry...
EDIT: ah as shown here Jimmy-Jims PW is 709

Obviously the higher the Available Capacity the less often you will have to charge the device and the longer it will live between charges.

I can kill a device in about 4 hours to dead flat when playing really intensive games (like doom) on it.

Hopefully some reference metrics will help move this discussion forward.

Regards,

If you could explain what you want a "battery timer app" to do perhaps we can just make you one.

I'm just guessing here, but maybe something that can tell you how long the Kindle's been running since the last charge?

 75% - 1061 mAh
 88% - 1245 mAh
100% - 1412 mAh
Pretty consistent- as it should be- if you take rounding errors into account. (mAh/%)
