Samsung SGH-I777 Galaxy S2 Battery Notes

The battery from my cell phone.

I have found that just getting a new battery for my SGH-i777 is not enough.  When I put the new battery with slightly different part number in the phone it will not charge.  If the phone was on it turns off and the green battery charging animation icon comes up for a bit then it also turns off and then back on / off / on to infinity.  Quite an annoying problem and quite obvious there is more than meets the eye here.  It could be as simple as Samsung wanting to sell batteries.  However given the NSA's involvement in everything communications now days I have to wonder.  After a little googling I found the following images in an article about how the near field communications circuitry is in the battery.  One has to assume the NSA knows we know to take the battery out of our phones.  So what to do?  Put a radio in the battery.  I have no idea what other "features" are in the battery but I have to assume there are a few.

The weird thing about this is even though I used an external charger to charge the new battery the phone refused to link to the cell phone system with it used to power the phone.   This in spite of the fact that the new battery with part number eb-f1a2gbu is called out as a replacement battery for the Galaxy SII.

Whether it is Samsung conspiring to sell more batteries or the NSA forcing some backdoor communications path on the cell phone companies I find the cell phone network to be highly oppressive.  It will not be a free media until someone comes up with something subversive.
