[Note 7 Themes, Apps, and Mods] Mr.Ultimate:
Updates...

So far I was very unlucky sourcing S7 battery which is my personal preference option due to this battery being most "up to date" tech variant available that should logically fit vs. the second best choice - a Note4 battery...

Also my donor Note7 is due in tomorrow as best case scenario, or latest Monday-Tuesday the 19'th-20'th of February, and I just dont feel like burning 30bucks on battery that probably does not fit by its thickness... (talking about note4 battery) , so I really want to take apart this note7 first and inspect the thickness of its original battery and the depth of the phone. What I mean in detail by that - please review this in-depth detailed report:

^^^ That is allegedly a note7 illustrated right there, this gives me hopes as if I stripped plastic and NFC chip from note4 battery I should end up with just about 5mm of thickness of the naked without NCF chip and w/o labels battery. However, I need to look harder about the S7 battery thickness as my eyesight would be strongly concentrated toward that if it was of the same thickness or even better if it was just under 5mm, but I am not sure...

I also contemplated maybe even retrofitting apple iphone 6/6s or 7 battery providing it fits by its dimension and voltage measures (yea just pulled it from thin air havent measured or researched yet) , but at least talking about voltages should be bout right and capacity may be close to that of S7...

Otherwise I was even thinking removing NFC/Wireless charging mechanisms from the enclosure so the excess pressure from battery wear and tear does not build up on either old original or new replacement retrofit batteries, give or take there has to be ~10% headroom for battery expansion which was really not thought trough in note7's (or if it was there was general battery design fault that was underestimated and exaggerated expectations from engineers who designed battery had failed them prematurely...)

I have meantime located S6 battery which is way too big and it by no means going to be fitted there but I have another few tests in mind until I get my properly fitting battery alternative, just to rule out some questions and variables...

I think Chinese market fellows are up to some news regards note 7 because just lately I have noticed increase spike of note 7 cases and accessories at least on ebay, it just spiked my curiosity, what are the plans of samsung for the remaining 3+million note7's that they got back from the recall, are they by slight chance gonna push Note7S with note8 and S8 release? what are the chances of that happening? :D

Also I was deeply considering how would note4 battery be of a worse technology build vs S7 battery, knowing everyone who I know had note4 in the past almost every single one of them batteries had expended and died out rather soon within first year or so... I am just very cautious about this happening prematurely while retrofitted in note7 ... where as with S7 as many people I know using them and it has been about a year now of heavy use and abuse including those using quick-charge, batteries still perform ok and not swelling which is more promising when compared to note4 battery.

As lucky as I can get just by doing online hunt, I found one seller on aliexpress selling copy replacement batteries where he claims battery measurements to be ~88mm x 40mm x 5mm, and here we are talking about non original battery that is rated @ 3300mah as per sellers web page , out of which I feel it is reasonable to believe that it holds quality ~2000mah capacity knowing how all these generic batteries are made... it is real hard to find genuine battery, unless if I want to wait 60 days, I can order from China... hard hard decision on waiting vs the availability. I really am leaning forward just straight S7 battery swap with best hopes of longevity , but the quest now is to get exact measurements and fast delivery.

PS: Anybody reading this has new original battery for S7 (SM-G930 / G9300)who can ship it over to me or measure it precisely X * Y * Z ?

Thanks
