That OEM 1800 mAh review really should be done with an almost virgin battery to see its original capacity. Maybe someone with a new one could send it in or someone who is going to get one could order it to you.

Still is good to see how it held up as all the other batteries have some mileage on them too.

But yeah I'd love to get a fresh new battery for comparison's sake

Pretty damn good for a year old. Want me to send you my OEM 1500 mAh when I send you the new Hyperion?

Yeah just realized the other one is 2 years old not 1... Even better! Anyway mine was made on April 28, 2011.

EDIT: You probably don't need it considering you have the two that were already tested and then two more.

Might have to send you one of my hyperions... I achieve around 6 hr screen on time over 16hrs total =].

Right now I'm at 47% over 13hrs with 2hr screen on time....

Sure, I'd love to analyze it. Just PM me when you're ready and I'll give you my address. When you send it, don't forget to include when you bought it and for how much to improve the statistics :)

Yeah I guess not, if it was a brand new OEM1500 then I'd say definitely do so to see how close the capacity is to 1500mAh.

Maybe I'll just buy one since they're probably super cheap now, but then again, so am I lol

Why is the voltage fluctuating on just that one run?

It's interesting to see that some of the OEM batteries are no better than some aftermarket batteries.

I honestly couldn't tell you, maybe some inconsistencies in some its internal wiring or cell configuration? (Though I'd imagine these batteries are only one cell).

It doesn't really matter much as long as it doesn't jump out of the phone's lowest tolerated voltage, and it seemed to clear up before the battary became exhausted

Which of the batteries will fit without a "fat" battery cover you'd suggest?

Probably the OEM 1800mAh, I'd really like to get my hands on a brand new 1800mAh OEM and some generic slim batteries to make an experimental recommendation haha. But I've had bad luck with 3rd party slim batteries compared to OEM....though 3rd party fat batteries are awesome IMHO

2000mAh is the highest iv'e seen there is a thread in the accessories.
And the 1800 mAh [OEM] is more promising and probably your best bet
+1


I may have a new Generic 3500 Fat battery to test soon (I'm sending my #1 in because it get's weird after 50% and shuts off or misrepresents it's battery %, which may had something to do with the inconsistent voltage spiking)

Give it 2 whole tests. Supposedly new batteries need to go through at least a charge cycle before they hit capacity but I haven't noticed this. I'd like to see if your date can back it up. The new Hyperion is amazing and I still have to convince myself to give it up to you for a few days and go back to my stock battery.

Yeah I'll run three initial tests and then use it for maybe a week or two and retest and see what's what

OEM1500 #4 review up (3rd was being used so I couldn't finish it yet)
OEM Slim Battery #4 "1500mAh" --Manufactured November 25th 2011-- $??.??

You made a typo here. The battery says 2010. Any info on how this battery was used? It must have been abused to be degraded down to only 800ish mAh capacity.
