Well, for my part, I'd rather spend my time deleting a message on how to
extend my battery life then having to read this message. I'd suggest
going off line and taking it up with the list moderators.
BTW, although extending the battery life of a cell phone is technically
off topic, it may still be of interest to Talks users since Talks is an
application that's always running, it's turning on the speaker and
adding to the general drain on the battery which a sighted user isn't
going to have to deal with. Also, as a screen reader, Talks is an
intregal part of using the phone for a blind person, so I think a list
like this should be somewhat flexible on what is and isn't off topic,
otherwise, enforcing what is and isn't on topic could overwhelm the rest
of the discussions on the list.
This is also a relatively low traffic list, so I don't see a need to be
too draconian when enforcing on topic discussions.
I agree that people with questions on other screen readers should be
steered towards other more appropriate lists.

This whole thread is off topic. No one is talking about Talks. It's
amazing how some people get away with it and others don't. I joined
this list because of the knowledge it provides. I didn't join it so I
would get off topic messages like phone batteries and their usage. Not
to mention the Iphone related discussions that have been going on.
Original message:
Chris,
Not sure about #1 but I do applaud your generosity in sharing ideas.
You assert that connecting the phone to ac mains at 13 Amps vs. USB
at 1/2
Amp helps to keep your battery healthy. Based on my EE studies, the
amount
of current (Amps) available to a device does not mean that the device is
consuming or having to cope with all that current. The amount of
charging
current going to a battery is dictated by the charging device (USB or a
wall-wart) and each are designed with current-limiting circuitry.
This is
dictated by Ohm's Law E=IR. The amount of current delivered to a
battery is
a function of the amount of voltage and the effective resistance in the
circuit handling that voltage. Simply put, even if ac mains looks like a
3-inch diameter water hose, ready to drench your flowers with water
coming
in at a rate of 20 gallons per minute, attaching a 1/4-inch hose to
the end
of it will restrict the total volume of water that can flow to a much
smaller amount, such as 20 Fl Oz per minute. Water flowing through a
hose is
the same principle as electrical current, which is coulombs per second.
So unless your wall-wart is defective and delivers a short-circuit to
allow
120 (or 220) Vac to directly couple to your phone,you won't get more
than
the recommended amount of current delivered to the battery.

Hi all.
I admit to my somewhat incorrect wording of the recommendation. I mean
any applications that are running in the background can drain battery
power very quickly. This could include Joikuspot Lite, a program to
allow your phone to act as a wireless hotspot, and so on.
Sorry about that. Yes, it's the application that are *running*, not just
installed.
Take care.

Number 2 doesn't make any since at all! You can have hundreds of

isn't going to cause the phone to use any more battery power unless you
start them and they run in the background. This has been the case for
all the phone out there.
Myself, I have about 40 to 50 things showing up in the App. Manager.
Things like Skype may add 5 or more items on it's own when you install
it. The KNFBReader Mobile Software could add another 5 or so items to
the App. Manager. YBrowser depending on the version and things you
install could add another 3 or so items. The VCM voices will add I
think
about 2 items per voice. So for all the English items that could be
another 14 items.
So what you are saying is this would cause the phone to use more
battery
just because they are installed. That isn't true being they aren't
doing
anything unless you use them.

Subject: [Talks] Two battery saving recommendations
Hello all.
I wish to recommend two ways of saving your battery power.
1. Instead of charging your phone via mains, charge it via USB, where
possible. It will do your phone's battery a world of good, since USB
draws a lot less power than mains, 500 miliamps and 13 amps
respectively. Also, enable power saving mode on your phone. This sets
your phone to use the battery's optimum life.
2. Look in your phone's application manager. If you see anything
unusual, go ahead and remove it. The absolute minimum you should have
on your phone are Talks, Talks Core and your chosen synthesizer, mine
being Eloquence. I discovered the hard way that the more apps I have
on my phone, the more it can drain the battery, depending on the app
of course.
Hope these help.
Take care.
