Snapdragon 845 phones like Galaxy S9 may sport Quick Charge 4+, here's what it means

Last week, Qualcomm announced the eventual Galaxy S9 chipset for the US models, Snapdragon 845. Previously, Samsung had given some details about its new Exynos 9810 processor, which, however, will most likely find its way into the global versions of the phone, as usual. What piqued our interest with the 845, however, was the promise for upgraded fast charging abilities, as the silicon has Quick Charge 4+ tech built in.

Samsung calls its own technology for pumping the Galaxy handsets full of electrons quickly Adaptive Fast Charge, which is probably what the S9 will use, too, even the US-bound Snapdragon version. One possible reason why Samsung doesn't go with Qualcomm's standard are the licensing fees it eventually have to pay (we know Qualcomm is big on royalties). Still, if Quick Charge 4+ in Snapdragon 845 offers a much better performance compared to Quick Charge 4, Samsung will have to leverage its own Adaptive Charge tech to match those abilities, or there will be drama in the forums and Reddit threads.

Qualcomm has rounded up what Quick Charge 4+ would mean for handsets equipped with Snapdragon 845, so we can gauge what might be in store when it comes to fast charging our flagships next year. The thing is that, to be Quick Charge 4+ certified, a handset has to fulfill all three of the newly updated specifications below, and, needless to say, come with the respective charger in the box:

  • Dual Charge: already an option in earlier versions, but now more powerful, Dual Charge includes a second power management IC in the device. Charging a device via Dual Charge divides the charge current, allowing for lower thermal dissipation and reduced charge time

  • Intelligent Thermal Balancing: a further enhancement to Dual Charge, intelligent thermal balancing is engineered to move current via the coolest path autonomously, eliminating hot spots for optimized power delivery

  • Advanced Safety Features: Quick Charge 4 already includes rigorous built-in safety protocols. Quick Charge 4+ goes one step further and is designed to monitor both the case and connector temperature levels simultaneously. This extra layer of protection helps ward against overheating and short-circuit or damage to the Type-C connector.

The combination of these requirements brings about 30% more efficient charging to the table, compared to Quick Charge 4, or about 15% faster charging speeds. These are significant boosts, but what's more important is that the whole setup stays much cooler, and thus safer, than before. The first device that has licensed Quick Charge 4+ for retail use is the ZTE subsidiary's Nubia Z17 which, however, sports a Snapdragon 835 chipset, so licensing the newest fast-charging tech from Qualcomm doesn't apparently require the newest chipset, too, as the chip maker announced 4+ after it outed the 835. 

Still, with faster, safer charging potential, Snapdragon 845-equipped phones will likely raise the bar for next year's flagships to charge even quicker and/or remain cooler in the process. The best of today's Android flagships require only 1.5-2 hours to go from zero to a 100% charge, and next year we could encounter phones encroaching on the one hour mark needed for getting to full, though we wouldn't mind if they take the same amount of time as the current crop, but sport larger batteries. If you want to see what a difference a fast-charging adapter included in your phone's package makes, have a look at our battery benchmark chart below.

DASH CHARGE FTW!!! Fastest One I'm sure!

Huawei Use Super Charge Technology

Huh? Samsung calls it Adaptive Fast Charge, only because it uses both widely available wireless charging standards...QI and PMA, on a single device. Inherently, they are using Qualcomm solution, its simply modified with a controller that uses 2 standards.

Even tech annalists are praising how good SD845 is. Getting 25-30% performance improvement in the same node ( slightly improved ) is seriously impressive.

845 looks to be a beast.

QC4 was announced a year ago but you still can't buy a QC4 Charger. if you bought the nubia Z17 then you can't even use QC4

Yes... I thought all SD835 phones would QC 4.0

Well yes the 835 supports QC4, but its up to the OEM to actually implement it.

I just hope the S9 doesn't come with QC 2 and 4GB of RAM again.

S9 will debut with 4GB while the S9 plus will be 6GB equipped.

21. mikehunta727 unregistered

Yeah especially since the new A9(?) is coming with 6GB of RAM. Note 8 with 6GB of RAM absolutely flies and is a multitasking beast with the extra 2GB of RAM. Really does make a difference

Let OEMs adopt QC3 first lol

All OEMs will use their own version of quick charging (except LG, Xiaomi and some of Sony) - Samsung = Adaptive Fast Charging - Sony = Pump Express - OPPO = VOOC - Oneplus = Dash Charge - Huawei = dont know their fast charge name, but they didn't even use Snapdragon Not sure why they keep avoiding QC.. Probably because they want to avoid extra patent fee for each QC charger they include in box.. but, 3rd party QC 3.0 charger should work just fine with their flagships (but maybe will charge slower)

Adaptive fast charge is the same as QC 2.0 technology wise. Samsung can't use the exact name since they have exynos variants too. Sony: Not sure there, but I'm pretty sure that's additional software using the IC provided by Qualcomm. VOOC and Dash Charge are same. But yeah, that's a completely different tech. Huawei: You're right. QC4+ is the best standard to be for now. It supports USB PD, which was a long pain point for most people and now resolved and the charging speed seems great too. Maybe we'll see OEMs actually implementing it.

Bro QC 2.0 came in 2015 & Adaptive charging from Samsung came in 2014 with Note 4 do you even remember or just simply whining :P

Quick Charge = Qualcomm Pump Express = Mediatek XZ Premium, XZ1 and XZ1 Compact have QC 3.0. XA1, XA1 Ultra and XA1+ have Pump Express I believe V30, Pixel 2 and U11+ have QC 3.0 as well
