GS3 wireless charging kit

Has anyone heard any news on the wireless charging kit for sprints GS3. I searched the forum and didn't find anything recent. I also know that there are third party kits out there as well as a official samsung back plate for verizon phones. I have read that all of these will work on sprints gs3 but we would lose nfc capability.

Still nothing from Samsung. There is a Powermat Case that I have been considering, but I really like my Otterbox Commuter and I haven't seen the powermat case in person, so I don't know how much bulk it adds or how well it protects the phone.

 

I am scouring the net looking for a case that provides good protection, allows NFC to operate, has an extended battery in the case, and has wireless charging built in. The touchstone type connection with strong magnets would be awesome for having in the car. I know I am dreaming on this, as it will probably have to be a custom job to get it all. Would be really cool though.

i did a little research on the custom touchstone job myself. not really sure i want to start doing that much to my gs3 yet. its just sitting on my coffee table, unactivated, warming up after riding around in cold ups trucks for the last few days. wireless charging is something that i would really like to use tho. its not that pluging a cable in is an issue. but my 2 phones prior to my og evo both went to the graveyard due to the charging ports being messed up. the less i have to stick something in there the better

Only for verizon's version. It will work with other carrier's versions but nfc will be lost. Apparently verizon's has 2 extra contacts behind the battery cover that are for the nfc antenna that is in the induction charging battery cover.

Not sure about Verizon's model, haven't gotten a chance to take one of those apart.

 

The Sprint model however, the NFC antenna is built into the battery itself. There are two contacts to the left of the battery accessible for what I assume is an external battery or charging solution built into a different battery cover. I haven't been able to cleanly follow the copper on the PCB to figure out exactly where it goes on the board yet. My assumption based on those being the only contacts back there is that it would be for a wireless charging solution of some sort though.

 

Keep in mind that NFC is designed to operate at low distance (1-2 inches) and anything that gets in the way will interfere, like the magnetic coils required for a wireless charging solution. Probably the only thing that wouldn't interfere would be some sort of contact-based solution like the old blackberry docks where there is true metal contact for charging.

There are 2 contacts on the left of the battery and 2 below the battery, next to the sim card. The Verizon wireless charging back has a wireless qi coil to charge the phone and a nfc coil built into the replacement back plate that uses the extra contacts that arent on the Sprint version.

thanks for the picture, tried to find one and i failed.

Interesting, especially since that looks like an identical battery to the Sprint version. That would mean the Verizon version has separate NFC antenna contact points on the board as well. Why is it that only Apple can tell carriers that the phone they make is the way it comes, no adjustments can be made. I mean the only differences between each "model" of iPhone worldwide is the frequency bands that they support, the hardware is physically the same.

    • In the conference call they had two question on additional spectrum. One was the 800 spectrum. They are not certain what will happen, thus have not really put it into their plans either way (sale or no sale). They do have a reserve level. Nationwide 800Mhz is seen as great for new technologies which I presume is IOT or 5g slices.  T-Mobile did not bite on use of their c-band or DOD.  mmWave rapidly approaching deadlines not mentioned at all. FWA brushes on this as it deals with underutilized spectrum on a sector by sector basis.  They are willing to take more money to allow FWA to be mobile (think RV or camping). Unsure if this represents a higher priority, for example, FWA Mobile in RVs in Walmart parking lots working where mobile phones need all the capacity. In terms of FWA capacity, their offload strategy is fiber through joint ventures where T-Mobile does the marketing, sales, and customer support while the fiber company does the network planning and installation.  50%-50% financial split not being consolidated into their books. I think discussion of other spectrum would have diluted the fiber joint venture discussion. They do have a fund which one use is to purchase new spectrum. Sale of the 800Mhz would go into this. It should be noted that they continue to buy 2.5Ghz spectrum from schools etc to replace leases. They will have a conference this fall  to update their overall strategies. Other notes from the call are 75% of the phones on the network are 5g. About 85% of their sites have n41, n25, and n71, 90% 5g.  93% of traffic is on midband.  SA is also adding to their performance advantage, which they figure is still ahead of other carriers by two years. It took two weeks to put the auction 108 spectrum to use at their existing sites. Mention was also made that their site spacing was designed for midrange thus no gaps in n41 coverage, while competitors was designed for lowband thus toggles back and forth for n77 also with its shorter range.  
    • The manual network selection sounds like it isn't always scanning NR, hence Dish not showing up. Your easiest way to force Dish is going to be forcing the phone into NR-only mode (*#*#4636#*#* menu?), since rainbow sims don't support SA on T-Mobile.
    • "The company’s unique multi-layer approach to 5G, with dedicated standalone 5G deployed nationwide across 600MHz, 1.9GHz, and 2.5GHz delivers customers a consistently strong experience, with 85% of 5G traffic on sites with all three spectrum bands deployed." Meanwhile they are very close to a construction deadline June 1 for 850Mhz of mmWave in most of Ohio covering 27500-28350Mhz expiring 6/8/2028. No reported sightings.  Buildout notice issue sent by FCC in March 5, 2024 https://wireless2.fcc.gov/UlsApp/letterPdf/LetterPdfController?licId=4019733&letterVersionId=178&autoLetterId=13060705&letterCode=CR&radioServiceCode=UU&op=LetterPdf&licSide=Y&archive=null&letterTo=L  No soecific permits seen in a quick check of Columbus. They also have an additional 200Mhz covering at 24350-25450 Mhz and 24950-25050Mhz with no buildout date expiring 12/11/2029.
    • T-Mobile Delivers Industry-Leading Customer, Service Revenue and Profitability Growth in Q1 2024, and Raises 2024 Guidance https://www.t-mobile.com/news/business/t-mobile-q1-2024-earnings — — — — — I find it funny that when they talk about their spectrum layers they're saying n71, n25, and n41. They're completely avoiding talking about mmWave.
    • Was true in my market. Likely means a higher percentage of 5g phones in your market.
