Why the Google Pixel 3 Charges Faster On a Pixel Stand Than Other Wireless Chargers (arstechnica.com) 124

An anonymous reader quotes a report from Ars Technica: Google's Pixel 3 smartphone is shipping out to the masses, and people hoping to take advantage of the new Qi wireless charging capabilities have run into a big surprise. For some unexplained reason, Google is locking out third-party Qi chargers from reaching the highest charging speeds on the Pixel 3. Third-party chargers are capped to a pokey 5W charging speed. If you want 10 watts of wireless charging, Google hopes you will invest in its outrageously priced Pixel Stand, which is $79.

Android Police reports that a reader purchased an Anker wireless charger for their Pixel 3, and, after noticing the slow charging speed, this person contacted the company. Anker confirmed that something screwy was going on with Google's charging support, saying "Pixel sets a limitation for third-party charging accessories and we are afraid that even our fast wireless charger can only provide 5W for these 2x devices." Normally we would chalk this up to some kind of bug, but apparently Google told Android Police that this was on purpose. The site doesn't have a direct quote, but it writes that, after reaching out to Google PR, it was "told that the Pixel 3 would charge at 10W on the Pixel Stand [and that] due to a 'secure handshake' being established that third-party chargers would indeed be limited to 5W."
In an update, Google said the reason has to do with the "proprietary wireless charging technology" it has via its Pixel Stand and other select wireless chargers. The Pixel 3 only supports 5W Qi charging; "Google's 10W proprietary wireless charging technology" is what will allow the phone to charge at faster speeds.

"Google says it is 'certifying' chargers for the Pixel 3 via the 'Made for Google' program and pointed us to one such device, a Belkin charger called the 'Boost Up Wireless Charging Pad 10W for Pixel 3 and Pixel 3 XL,'" reports Ars Technica. "Belkin's description is very enlightening, saying 'Made with the Google Pixel 3 and Pixel 3 XL in mind, this wireless charging pad uses Google's 10W proprietary wireless charging technology. It's certified for Pixel, so you know that the BOOST UP Wireless Charging pad has been made specifically for your Pixel 3 and meets Google's high product standards.'"

      • LineageOS will give you some extra years of support.

      • With the way the updates have been lately that isn't a good thing. With Android 9 Google broke Bluetooth, fast charging on the Pixel XL, wrecked battery life, accidentally changed battery settings for apps, and numerous other problems. Android 8 was constantly a battle of them breaking Bluetooth every other week. At this point I think half the reason the other manufacturer's hold back on the updates is because Google tends to release them haphazardly and break stuff.

          Same expectation and experience with the Nexus 5.

          Slightly different conclusion though: Don't buy *expensive* Android phone models as they are likely to be throwaway devices security-wise in two years.

          It's also worth noting that this was a $299 phone with decent hardware in 2012, which was rare. Considering you paid 1/3rd the price of an iPhone/Galaxy S you could afford to upgrade it twice (so total of 6 years of primary OS update support, plus hardware upgrades) compared to the competition.

    • 100% this. Google fought and bitched and moaned and campaigned and actively brainwashed users to think that USB Power Delivery (which is ALSO proprietary) is the only acceptable, safe, safe, good, etc. option. (This all despite the fact that their own products violate the spec, including some in unsafe ways.) Now they turn around and pull this shit?

      Fuck you, Google.

        To be fair, there's a pretty big difference here.
        1) qualcomm's quick charge actually violated the USB spec. Their quick charge still used USB cables to provide power. micro-usb wasn't designed to handshake or negotiate the cable's capabilities to the charger and the phone. The usb cable standard did NOT allow for quickcharge power draw. That actually IS dangerous.
        2) Google's 10w proprietary standard is negotiated, and there's no intermediate medium (unless you count the air molecules between the charger and the device, and I'm pretty sure there's no specification defining their behavior)

        By no standard definition is usb-pd proprietary. It's no more proprietary than USB is (so if you consider USB proprietary, well fine, here's some more tin foil).

          But why do 5W Qi and 10W proprietary when most other phones do 5W Qi and 10W Qi?

          Qi already goes up to 15W (though I'd imagine there are thermal concerns), so why do we need a proprietary Google standard for 10W when everybody else is just using 10W Qi pads?

            Because some bright product manager is banking on their model of the market that predicts a higher overall profit to Google via original hardware sales and proprietary protocol licensing.

            • Exactly! And they've seen Apple make even music playing require a per-device-supported royalty payment and get away with it.

            • by Guspaz ( 556486 )

              That list may not be complete (or there are just lots of phones out there that support 10 watt charging without being certified). There are no Samsung phones on that list, and they're shipping 12w Qi chargers for their latest phones. Previous models used 9w Qi chargers.

            • There are surprisingly few phones that are certified for > 5w Qi charging. I'm guessing there's gotta be a reason for that.

              Probably a shitty database. I just looked up the two devices we have in the house that support high-speed Qi chargers just fine, and both of them are listed in that list only with the Basic Power Profile.

              Or maybe certification isn't all that it's cracked up to be.

              Having worked with wireless charging technology, I am not surprised. Despite a certain subset of consumers and manufacturers being in love with it, it's actually a pretty shitty way of delivering power. The limitations are mostly thermal. Sure: you can get do >5W charging, but all the other metal content of the phone is heating up, too, including the battery. Batteries charging while hot will have reduced lifespan or, at wo

                For example, in the car, I have both a 2A wired charger and a 500mA inductive. If my battery is in reasonable shape, I just pop the phone in the inductive charger/holder thingy and off I go. It's easily enough to run Waze and stream bluetooth music without draining the battery at all, and if I really need 2A (or i

                  A phone is ~3000mAH. Even if you charged a phone once a day on an inductive charger at 10% efficiency, that would be (rounding up) ~1KWH = (3000mAH * 10x loss * 30 days/month)

                  Do be careful: 3000 mAh is not a measure of total energy; it is a measure of electric charge (coulombs, if you want to get technical about it). To convert to energy, multiply by the nominal voltage of the battery you are talking about: 3.7 V for a typical Li-Ion. By that measure, the battery's energy capacity is about 11 Wh. Chargi

                  • Just checked with a Kill A Watt, the power draw when there are no devices handshaked is 1W.

          • For some unexplained reason, Google is locking out third-party Qi chargers

            I'm sorry, is this Apple we're talking about here or Google? Or is Google finally catching up to Apple's standard operating procedure. In other words we're going to end up with Apple (Business practices) Classic and Apple (Business practices) from the Other Guy.

          • But are they actually doing 10W Qi? My understanding is that they AREN'T using a 10W standard, but a 10W proprietary model. I'm not very familiar with this topic, but I'm looking up some 10W Anker chargers on amazon, and they seem to indicate that they have a 10 watt "Samsung" mode and a 5 watt "Standard mode".

            • by Guspaz ( 556486 )

              That's possible (even if Qi itself does go up to 15), but if you've got products on the market like Anker's chargers that aren't necessarily having to license things and still support both "Qi" 5W mode, and "Samsung" 10W mode, and "Apple" 7.5W mode, that's still not as bad as Google actively blocking anybody who doesn't pay them money, no?

        • 1) qualcomm's quick charge actually violated the USB spec.

          It never claimed to BE part of the spec. It didn't violate it. It ignored it (or extended it since it didn't break any existing functionality).

          Standard USB cables are fine. The extra power isn't gonna fry a cable - any cable crappy enough to get fried by a Quickcharge adapter that doesn't get a handshake would be fried by regular USB anyway. If handshaking fails, Quickcharge fails safe. If it succeeds, THEN Quickcharge comes into play. It's no more dangerous than anything the actual USB Implementers Fo

        Yeah, that sounds horribly proprietary, and is the worst kind of Vendor lock-in.

          USB is proprietary, locked down, expensive, etc. It's just widespread.

          Quickcharge being proprietary is no worse then USB being proprietary. On technical merits alone, Qualcomm has been beating the shit out of the USB Implementers Forum when it comes to fast charging shit.

    It's so they can charge you MORE for the faster charger. DUH I prefer slow charging anyway. Typically safer charges are when you slow charge. And it typically has less chemical impact on the battery life.
  • I'm not surprised they're limiting power draw to the official standards for unknown chargers.

    They're what, 50% efficient?
    So charging at 10W means 10W of heat in the charger. Sitting right next to the battery, that you can't charge when it gets over 45 degrees or you risk it catching fire.

    • So charging at 10W means 10W of heat in the charger.

      The way energy conservation laws go, charging at a 10W rate means that the generated heat will be at the level of (H - 10W), where H is the total wattage sent to the charger. So for example if 12W are being sent to the charger and 10W of that is being used to charge, the heat will be 2W worth.

      ...and, according to your arbitrary choice of efficiency, 5W of charge means 5W of heat. No evidence that this is "right next to the battery" or that it would matter in the slightest to the battery's temps, so your point that the incremental addition of 5W of heat somewhere must result in the overheating of the battery which is both extraordinarily unlikely and should already be protected against inside the phone. Furthermore, it's the job of the charger to make sure that it doesn't overheat the phone, a

      I believe the official QI standard supports 5W, 7.5W and 10W. It actually goes as far as 120W IIRC but that's not relevant here.

    • Sitting right next to the battery, that you can't charge when it gets over 45 degrees or you risk it catching fire.

      Why be so presumptuous? It's up to the *phone* to reduce it's charging rate if there's a temperature issue. It's not up to the phone at all to ensure that a device connected to it doesn't overheat or otherwise.

      And phones already protect the battery from overheating during charging by turning off the charge.

  • Looking over Qi chargers for the past few months, all of them seem to list max 7W with various iPhones, and I think 12W with a number of Android devices.

    Aren't those all Qi? Apple is for sure, so why would the pixel have a max of 5W when the iPhone can do 7?

    That said, I've been doing some reading about this, and from what I understand, the standard itself doesn't actually specify quick charging, so manufacturers have been left to invent their own method.
