Just bought a set of "Sensation" replacement OEM Batteries with charger for $12 US
Marked as 2450mAh ( stock HTC EVO 3D is 1700mAh) but most likely like all OEM's a bogus, made-up number that sounds cool! ( look at how it's displayed on the battery )
2X 2450mAh Gold Battery Charger for HTC Sensation 4G G14 G18 G21 Sprint EVO 3D | eBay
Not selling, nothing to with the dealer, just a report of my findings and a simple question:
Showed up in a week, both batteries work, and power the phone. Charger works changes color when charging complete. There temperature seems to be acceptable.
I installed and ran (https://play.google.com/store/apps/details?id=com.nema.batterycalibration&hl=en) battery calibration to run a fair test. Cycled both batteries through 2 full discharges ( down to 1% ) then full charge ( 100% ) and they preform as good as or a TINY bit better then stock ( running on Midnight 3.4.5 normal to slightly under-clocked and HTCCM10 build 20130102 )
Ok now to my question, or observation and concern. The price of $12 is WAY too little most people tell me this must be rejected HTC batteries re-branded. I understand that 2450mAh is just a made up, meaningless number. So if it lasts me 6 months or maybe a year then I'm more then happy, but there is no way to tell when or if they will fail or how.
Q 1 ) By cheeping out, will they thermal? Could have a meltdown in my pocket?
So far it has not, but it's still cheap crap from China, every day it holds a little less charge
Q 2 ) So I created a new "batterystats.bin" file that matches them, how will that effect changing ROM's I like the ability to switch between "stock-ish" Midnight 4.0.3 and 4.1.x HTCCM10
Has no impact, only used to draw a pretty graph. Phone reads from chip in the battery
Q 3) How come TWRP does not have a function to clear the "batterystats.bin" file. I assume it backs it up or does it? I think a cool function would be to have 2 to 3 backups of "batterystats.bin" so say if you put back in your stock battery you can switch back to it's profile, etc.
Never got an answer but it's a moot point since it does nothing important
Update:
to sum-up this thread with an overall recommendation is:
1) The "Seidio" brand uses higher quality materials and is generally recommended ( they are made in Japan rather then China ). Anker is also highly recommended but based on people's very positive experiences. Bottom line only go with a known good brand not what's deal of the day on eBay.
2) The Seidio "Platinum Series" - 2X Extended Life Lithium-Polymer Battery ( there single cell is 1900mAh x2 should be around 3,800mAh ) for HTC EVO 3D is currently ( as of this writing ) being dumped, no idea how long the deal will last:
Amazon.com: Platinum Series - 2X Extended Life Lithium-Polymer Battery for HTC EVO 3D: Cell Phones & Accessories
$9 + s/h
Platinum Se 2X Extended Life HTC EVO 3D Li-Po Battery - CowBoom.com
$7 + s/h ( which came out to be $12 for me my lucky number )
3) Your phone talks to the battery and if you get all the readouts then the battery works. With that said the quality of the battery determines how much power is stored after daily charging. That is the stock battery is 1700mAh not because it sucks but that number is an average of it's 2.5 year life expectancy. Thus eBay marketeers set there life to weeks if not months to get outrageous numbers. ( This from my research around and asking fellow EE's )
Thanks for everyone's input, I hope this helps others BEFORE they click "buy now"
