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 - Quick Charge 4+ vs Quick Charge 4 in Snapdragon 835...

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

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.

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

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.

845 looks to be a beast.

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

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.
