Contrary to what people believed, ~DS actually works adversely on the battery on a few kindle devices.
Since I've only owned the Paperwhite and the Oasis, I can't say for the older Kindle models.

If ~DS works on the kindle fire tablet, it would definitely drain the battery, no doubt about it!

On the Kindle Paperwhite, the ~DS also reduces battery life, since the Paperwhite can't fully turn off the screen light; and thus the light stays on draining battery in the process of it being unused; much more than it would with loading different ads on the device.

I actually expected that ~DS would reduce battery life if the screen light remains always on.
And I can understand that with wifi on, the device continues to poll the network (since it's in active mode), and thus decreases battery levels that way.

But my results with the Oasis leaves me a bit puzzled,
I mean, the screen light goes off completely (at least that's what I believe); and it has an airplane mode.

Without disabling the screensaver (~DS), my Oasis drains about 2-5% a day; screen light off, airplane mode on.

Yesterday I enabled ~DS, in an effort to save battery, however, today (18 hours later), the battery went down from 95% to 61%. That's a decrease of 34%.


I didn't expect those battery results, and would wonder why?
Perhaps it's the touch screen that remains active?

And if it affects other devices as well?

Since I have the paperwhite, and the Oasis, I can only verify the results on those devices.

I presume the same would happen to most other kindles, save perhaps for the older models, that don't have a touch screen (like the DX or older models) or something?
Not sure how it'd affect the older models.
