Hello List,
I don't feel that the battery is much different in the M-power than it is
in my original unit. When one is on line or listening to streaming audio,
that kind of operation is definitely going to drain the battery very
quickly. It could go down or flat between five and ten hours when on line
for the better part of that time. If I'm simply downloading Email and I
turn off wireless connectivity after downloading my mail, and I take care
of the Email, read a chapter or two from a book as well as read a magazine
article, and write out some things, the battery will probably get 15 to 20
hours like the old unit does presently. The newer circuitry acts a bit
differently towards the battery so one must consider a few suttle
differences. I marvel at how quickly I can normally bring the battery to a
full charge in two hours. This is especially true with my older
unit. This same thing can be accomplished with the newer M-power if you
don't drain your battery much past ten percent. You should bring it to a
hundred percent easily after two hours. In the M-power, the gage will
still say a hundred percent even though the AC adapter is disconnected
after a full charge. By comparison, my older BN unit goes to 99 percent
immediately after the AC adapter is disconnected after being fully
charged. I recently had a newer battery put into my older unit. Should
the battery go completely flat, it may take up to eight hours for it to
charge and the battery gage to be properly calibrated. Having more memory
and a faster processor may put more demand on the battery as well. I tend
to think people are getting a handle on how the M-power and battery
function these days but I don't feel it is a big problem unless one has a
defective battery which happened in a few units which were sent out early
on. Humanware did a fine job in getting right to the problem and this is a
good thing!
I also like the idea of having an external plug in battery available just
in case. Of course, one must keep that battery charged as well.

Hi
I am considering buying a Braille Note M power, so could some one please
explain the issue with the battery? What I am wondering is - does the
battery lose it's charge very quickly, or does the battery last a very long
time?
Regards James

If that is the case it really is pretty good I haven't found any other
units that can claim that.

The M power manual says they get over 20 hours of battery life.

The real question here is. Since the old units got about 21 hours how
much do the new ones get? Having asked that question remember the
hardware is different a more powerful processor for example. Also how
much to you get on the new machines total? Even if it were 10 try and
find a laptop that will run that long.

It says the battery gauge is accurate, but I also did a recalibration
just to know it was done.
Hey, having nothing to compare it to, I'm not complaining about the
battery. But if you guys say it's not as good as older models, then you
have something to base a comparison on.
