Google may kill proprietary quick charging; VOOC, DASH etc

[dizmo]

Well, it looks like the quick charging method may no longer be something to consider when you go to choose your new phone.

 

 

In Google's recent Android Compatibility Device Document they state:

Quote

Type-C devices are STRONGLY RECOMMENDED to not support proprietary charging methods that modify Vbus voltage beyond default levels, or alter sink/source roles as such may result in interoperability issues with the chargers or devices that support the standard USB Power Delivery methods. While this is called out as "STRONGLY RECOMMENDED", in future Android versions we might REQUIRE all type-C devices to support full interoperability with standard type-C chargers

Basically what this means is companies proprietary charging methods that alter the Vbus voltage, or "alter(s) sink / source roles of pins in order to use your proprietary charging method" will no longer be allowed on Android devices. They will instead have to use USB Type C Power Delivery protocols, which basically means there will be one type of charger and cable.

 

While it is currently only "strongly recommended", as we can see they've stated they may require it in future iterations of the OS, which wouldn't surprise me.
One has to wonder if Samsung's horrible Note7 failure has something to do with their decision.

 

On the plus side, it also states that USB Type C phones must be able to use both 1.5a and 3.0a chargers. Faster charging for all?

 

Personally, I'm torn on this.

One one hand I think it's great that there will only be one cable/charger type.

On the other, this stifles innovation a bit. I'd say that Dash charging is superior to the others, as the phone doesn't heat up nearly as much. If they no longer allow companies to do their own thing, we might not see advances like this in the future.

I also wonder if Qualcomm's solution will still be an option, as it's built into the SoC. Their QC 4.0 was supposed to hit 28w, or around a 30% increase compared to QC 3.0.

What do you guys think?

XKCD has a wonderful comic on this very topic that sums up my thoughts on this very nicely

I think someone at Google got a look at Samsung's profits for this quarter, after the note 7, and got scared. So they decided that it wasn't worth the hassle and just said no to quick charging.

I liek the idea of a standard for usb c but I think it would stop innivation but then we have safety issues with the current number of standards.

This is completely random and unrelated, but they need to fix the ability to rollback in Chrome OS.

 

 

(I work on Chromebooks, and the school districts are always using an older version for no apparent reason, and Chrome OS likes to randomly update to the latest version when you aren't looking)

chrome os realses on the stable channel rarely, if ever  have bugs.  idk why they would want to roll back, at my school they are always kept up to date

I don't either. It's a massive pain in the ass.

 

Right now, one of the school districts we service, are using version 53, but Chrome OS is at 54, so we can't make recovery USB's for their units, because Google will only allow you to make a recover for the latest version.

smh, they need a good wack, on my personal chromebooks and desktop im on Chrome 56, the nightly resales and don't have any bug issues....like google good at fixing stuff internally. 

[Okjoek]

Quick charge isn't really important to me. I leave my phone to charge at night before I fall asleep and I'm usually good for the whole day.

[Doobeedoo]

Proprietary yes I guess so. But doubt there won't be quick charing implemented pretty much any most new phones, specially flagships.

and we though W10 was bad 

[tlink]

i hope they use the tech oneplus used in the oneplus 3, that was really good.

Dash charge is objectively the best fast charging solution yet.

 

It's retarded to kill it.

A question for the quick charge "fans". Do any of you heard/read about the drawback of quick charge? If you charge a lithium-ion/poly battery outside its charge characteristic it will seriously reduce its durability. In most cases you want to charge a lithium battery with a current that is half of the battery's capacity. Lets assume we have a 3 Ah battery, then we have to charge it with max 1,5 amps. That is 6,3 W (4,2V*1,5A), on the other hand qualcomm pushing 28W through the poor battery... No matter how you slice it this wont do much good for the battery's longevity...

Most phones are replaced within a year or two of manufacture anyway, so I don't see it as a huge issue. Plus if it's something you find useful, the added cost of replacing the battery later on in the phones life is negligible. Those who don't want to use it can use a basic charger.

QC works by upping the voltage, and it varies in the amount of voltage that it transmits. As far as I can tell, it's always within the receiving batteries designed tolerances.

I'm pretty sure batteries are designed to take a lot more these days then what they used to be.
I know that OP claims that Dash Charge has no adverse effect on the battery vs slow charging.
I used to charge over night. I now charge for 20-30 minutes in the morning. Having legitimate fast charging is a game changer.

meh

V10 owner

removable batteries

batteries go for 10$

QC half an hour every morning for 100% > being screwed when you forget to leave it in charge overnight with slow charge 

[jagdtigger]

I let Dave explain this:

 

Since the chemistry didnt changed much this is still accurate. If you surpass the batteries voltage it wont do much good, same with current. And drop the BS excuse that ppl will change their phones, its just one more trendy thing to do but its totally unnecessary...

 

I just cant understand why many people so eager to damage their own stuff...

[porina]

Battery chemistry is generally well known and understood, except for a certain recent Samsung... this is a situation where you can have your cake and eat it. You don't have to slow charge to preserve the battery, but certainly there is an upper limit you mustn't cross to maintain safe working and a long life.

 

Back on the chargers, we already had a moment of industry agreement with the previous move to micro-USB chargers, even if they can support different quick-charge methods to overcome the then limitations of USB. With the higher current available with the type-C connector standard, I hope this would negate the need for propriety methods to exist and they will die out over time with increased C adoption.
