Bars on indicators on cell phones

[Guest]

Apparently many cell manufacturers don't want you complaining about poor
reception, so if you are receiving any signal at all, the phone will
show 3 or 4 bars of signal.

Allegedly Sanyo is switching to a more honest signal meter in its newer
phones.

It appears they haven't in their battery meter. I woke up this AM, to
find the meter on empty on my new 7300 and a LOW BATTERY PLEASE CHARGE
message on the screen.

So I put the phone to charge, I moved the charger after 5 minutes and
the phone, now unplugged, showed 3 bars (full) of battery strength.


THANKs for a dishonest battery meter Sanyo.

This appears to be true. My new 4920's appear to pull and hold
the same solid signal as my 4900's, but where my 4900's display four
bars constantly, my 4920's fall back to three or two most often. Yet
the signal and sound are the same, as far as I can tell. In fact
people tell me that the signal sounds stronger on my new phones.

I think there's a sensible explanation for the battery
indicator situation you described, but I'm not qualified to comment on
it.

There's a phenomenon called "Surface charge," where a battery's terminal
voltage can quickly rise under load, even before it's had time to absorb
much energy. All the "bars" gauge has to go on is terminal voltage (and
temperature), so you might see a high reading at first, which should drop
to a more accurate level after a few minutes once the surface charge
wears off.

Also, it's harder to measure state-of-charge for an LiIon battery,
because its voltage doesn't change much compared to other chemistries.
Some devices manage to do a better job of it than others, though.

In other words the Sanyo charge inidicator is worthless.


Sure seems accurate on my Motorola v400.

Only in Phillie-speak. He didn't even use the word Sanyo, Phillie.

Your attempts to concentrate on your own illogical vendettas are
pathetic.

I've been searching for the right word for Phillipe's attitude here, and I
think you hit it "spot on" Rob. It does sound like a vendetta, where he
either got fired from SPCS, or works for SPCS in some capacity and got
passed over, because of his self righteous hypocritical attitude here.

The battery indicators work much like a
gas gage in your car I suspect. I'd still
buy my Sanyo 4900 if I had to do all over
again.

Have at it, they're on eBay all the time.
