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.

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.

      Kind of amazing that T-Mobile is still holding onto that speed title despite Verizon all but killing off lowband 5G on their network. While Verizon is mostly being evaluated on mmWave and C-band performance, T-Mobile and AT&T's average 5G speeds include their massive lowband 5G networks that are significantly slower.

      Yup. Very true. We were originally on an Everything Data 1500 Plan, which got Unlimited Minutes thanks to Marcelo's "Loyalty Benefits" offer. We then switched to Unlimited Freedom (with the Free HD add-on that Sprint originally wanted $20/month per line for.... remember that?) because the pricing was better with "iPhone for Life", vs. the "Loyalty Credit" for staying on a Legacy Plan. After that, I ran the numbers and switched us over to Sprint MAX, especially for the international travel benefits. There's absolutely no reason for us to switch to Go5G Plus or Go5G Next if we're going to do BYOD by purchasing from Apple/Samsung/Google directly as we've been doing. These new plans aren't priced for current customers to switch to. They're priced for new customers, where they throw in a free line, etc. It's gone from "Uncarrier" to "Carrier". What a shame.

      Strange business model that they keep around all these pricing plans. 1000s of plans per carrier is reportedly not uncommon.  Training customer support must be a nightmare. Even MVNOs have legacy plans. A downside of their contract mentality I guess. Best to change contracts during a recession. But then all carriers try to squeeze out legacy plan benefits as they grow old.

      Everything "Uncarrier" is becoming "Carrier" again. Because of the Credit Limit that T-Mobile put on our account for no reason at all (and wouldn't change/update the last time I checked all the way up to the CEO), I don't plan on buying/upgrading our iPhones through T-Mobile. I'm going through Apple directly. Looks like I'll be going through Google and Samsung directly for our other lines for upgrades. Also, we're staying on Sprint Max given the ridiculous pricing for Go5G Plus. On Sprint Max, we currently pay for our Plan: $260 for 7 Voice Lines $25 for two Wearable Lines. (One is $10/Month. The other is $15/Month because the AutoPay discount only applies up to 8 lines.) Total: $285/Month vs. Go5G Plus (Per the Broadband Facts "nutrition label" on the T-Mobile Website): https://www.t-mobile.com/commerce/cell-phone-plans $360 - ($5 AutoPay Discount x 7 Voice Lines) = $325 The Watch Plans show as either $12/Month or $15/Month: https://www.t-mobile.com/cell-phone-plans/affordable-data-plans/smartwatches So this is about the same for the wearables as what we're paying now. Overall, it's quite more than we're paying now to switch plans. Ridiculous....
