lol at this extended battery

like no...just no! $40 for 1800mah?

I complained to them since leading up to that the best extended I found (mind you I'm looking for one that will still fit under the standard battery cover) was a 1700mah for only $10.

I messaged them and said I'd buy the 1800mah for $15, but any higher than that is preposterous and I'll be giving good ol' china some business

new MUGEN power?
lol! is this a Honda??

Let us know how that works out I'd be interested in one for $15

Those mAh ratings are basically made up. The "1800 mAh" won't last any longer than the "1700 mAh" one. Actually, it might, because it's Mugen and I hear they may use high quality materials, but that might be just the perceived value effect.

Anyway, the point is that the mAh ratings of these batteries are essentially meaningless. The only way to know which will last longer is to do an actual test.

The overpricedness would surely be explained then

will do!

Idk what else one could really go on to figure out the battery's capacity
I mean the voltage can't change so the mAhs are the only variable really.
As for it being a Mugen and therefore "must" contain high quality parts....well I'd hope so since Mugen batteries are always obnoxiously overpriced .

I was wondering though, is there a way I could check the mAh myself when I get the battery?? like with a multimeter or something?

In short, no. mAh is a performance metric, not an electrical metric like voltage.

It's sort of like, for the inevitable car analogy, horsepower on a car. Imagine a car industry where no one regulated how manufacturers rated their engines for power output and no one ever cared enough to actually test a car for power output. You'd have manufacturers pumping nitro into the engines to get stupidly inflated measurements, you'd have manufacturers measuring HP at the crank instead of at the wheels, and you'd have manufacturers simply making numbers up to be "one better" than the competition. No one would ever really know, since no one ever does any actual independent tests (who cares enough to set up any sort of valid scientific test for a bunch of $10 eBay batteries?).

mAh ratings are, as I said, performance metrics. There are lots of ways to measure the performance of a battery. There are so many variables that have a huge influence on the final "rating," such as temperature and current. A given battery will measure a vastly different mAh rating when putting out 200 mA at 75 degrees than it will putting out 2000 mA at 15 degrees.

And that's assuming they do any measurements at all. Do you really think the generic, no-name battery manufacturer in China shipping out batteries to the US via eBay for $10 a pop for 100 different phones is really setting up and doing valid, honest tests of these batteries for performance? Of course not. They're assembling the batteries to the approximate size and voltage of stock and then slapping them with a performance number that's one higher than the other guys so they sell a few more.

These are the same guys who, under contract to a US manufacturer, paint children's toys with leaded paint to save 2 cents per unit and hope no one finds out or else the large US manufacturer will cancel the contract. Imagine what they do with stuff they're selling direct to consumers through eBay.

Interesting, that does make sense. It sucks that I cant check the battery's specs scientifically. I'd have to see if I notice the ~13% increase I should be having I guess (or 20% if I got the 1800mAh)

[jonnythan]

Well, you can, just not very easily. One of the easier ways would be to turn the phone's radios off and disable all background services, set it to a certain brightness, let it fully charge, then play a video in a loop until it dies. Repeat this 3 times for each battery and measure the time.

Another way would be with a special battery charger that has a discharging function. There are some fairly fancy universal li-ion battery chargers that will charge your battery and then do a full discharge, complete with measured mAh rating (it calculates this based on current draw and time).

Of course, neither of these tests will exactly correlate to real-world usage but they can potentially give you a good idea of how various batteries stack up against each other.

[iviyth0s]

Yeah, I guess I'd just have to see (hopefully outside of the placebo effect) whether or not my battery life seems to have improved.

I'd love one of those charge/discharge testing units, but seeing has I am too cheap for the $30 price hike on the battery, chances are high that I am too cheap to buy that unit. (unless it was a universal unit).

Hopefully I'll hear back from the Mugen guys soon, or I'll just pull the trigger on the "1700mah"unit

If you don't mind the additional size, go with the seidio 3500 battery.

This battery easily lasts me 2 days between charges with my normal usage. Heavy users would easily get more than a day out of this. The only complaints are the volume rocker is harder to adjust, and the back cover will sometimes pop off. But this battery is definitely lasting much longer than the stock one.
