Battery issues are a primary reason people upgrade their phones.

most people upgrade because the cell carriers pitch free (or nearly so)
phones. i get calls every so often telling me i can get all sorts of
stuff just by renewing.

So you're agreeing with me.

no. you said it was due to battery issues and i'm saying it's because
people like free phones (and $50 is 'free' given the lengthy contract
they must commit to), especially when they're going to be staying with
their carrier anyway. for those who switch carriers, they get a new
phone.

the hand-me-downs end up on ebay or craigslist
and have very good battery life (i've bought several that way, contract
free).

Then you've been buying relatively young phones.
Batteries have a useful life of 1-2 years.

actually, i buy older ones that do what i need. my last phone was new
in 2004 and it currently lasts a couple of days between charges (and i
didn't prime the battery either ). that's less than when new but
certainly more than adequate for most people. the only reason i
switched was because i wanted some new features.

... with the iPhone a notable exception, which is why the criticism is
justified, not to mention the built-in memory instead of a more
user-friendly memory card. "It's not a bug, it's a feature!" LOL

yes it is a feature. with as much as 32 gig built in, who needs to mess
with cards?

Small comfort to those who bought smaller ones.

that can happen, but given the resale price of used iphones, they stand
to make a profit by upgrading to a larger capacity model.

The number 600 it at the high end. Other than an initial charge
and discharge to calibrate the low battery level electronics
there is no gain in a "few charge and discharge cycles". The
gain in capacity after a "few charge and discharge cycles" comes
with other battery technologies. Not Li-ion.

Can I ask you if all discharge/charge cycles are equal?

Full charge cycles are at most 600

More like 1000 for the best current batteries.

Current as in amperage, or as in up to date?

Can you show a link?

Can you?

Yes.

Then please do so.

How would I find a link to substantiate your false claim?
It is up to you. It's your claim.

Apology accepted.

So how does one put this into their camera?

Not even a gracious loser. Why am I not surprised.

Last I looked the group was rec.photo.digital. When you
can find one of these batteries that you can put into a
camera then I'll admit defeat. You can't. All you can do
is find a claim by Apple that their new technology battery
can last up to 1000 charges. Your Apple battery is no more
a reality to rec.photo.digital than the experimental Li-ion
batteries that can be charged 10,000 times.

ISTR a new lithium ion needed a few cycles but when I checked on how
much percentange improvement the extra cycles provided, I couldn't find
any clear recommendation.

It's going to vary by manufacturing technique and rating technique.
Ratings may understate or overstate capacity depending on whether the
manufacturer wants to emphasize density or endurance. Only the
manufacture's performance graphs will tell you what you want to know.

I am curious about why some people are so obsessed with battery
life--batteries are the cheapest element in digital photography. Some of
the satements in this thread (_Not_ McMurtie's post, incidentally)
approach the medieval "how many angels can dance on the head of a pin"
question.

Be that as it may, I paid AUD$1,700 for a camera body and the batteries here
in Australia are AUD$170 each so if I buy two spares that means they are 20%
of the cost of the body, personally I would like to know what sort of life I
will get from them.

Try the 3rd-party suppliers. Some, at least, provide good batteries -
indistinguishable in performance from the manufacturer's originals, and a
/lot/ cheaper than AUD$170.

Li-ion batteries start to die from the day they are manufactured.
I believe they generally have a useful life of five years.This occurs
even when not being used. So unless you actually use all your spares
from the start it may not be the best decision to buy now instead of
waiting until you actually need another battery.

If you want your unused spare to last you can slow down the chemical
degradation of the battery by keeping it charged at about 60% capacity
and storing it in the refrigerator.

True.

More like 2-3 years, depending on technology.

Funny that.

Three Li-Ion batteries from three different manufacturers; one being the
OEM battery, one an inexpensive generic backup for that camera, and the
third being an external power-pack (brand DigiPower with DC-DC voltage
converters for all my cameras that I mated-up with solar panels for
recharging); which I use for a 9 year old camera are still providing full
charges. All purchased when I purchased the camera 9 years ago. I was just
using that camera yesterday on the original OEM battery. The backup generic
is used to power an IR-flood frequently. The OEM battery itself has alone
provided over 300,000 photos on that camera.

This is why I never believe anything that is parroted by others, nor by
websites on the net, no matter how many of them are saying the same thing
nor how reputable everyone claims them to be. Unless I test it myself to
find out if it is just more inexperienced and parroted net-BS.

Misinformation on the net breeds exponentially. Until truth and facts are
just a vague shadow found on the singular 8,339,004th hit of all Google
pages presented.
