I think that's a bad idea as they will have specified a battery suitable for 18W charging ...

Battery should last for ages, anyway. It's 5000mAh, very close to pure AOSP, and the display is by no means large.

If you endlessly play with the camera motor, it might drain a bit faster, but otherwise, I suspect this will have the best battery life of any phone in the small flagship class.

I'm fine with QC3.0, since I've used that a lot.

But if it does come with QC4.0 then I couldn't be more happier.

With the battery capacity it has, I don't think I need to charge it all the time so QC3.0 is something extra for me.

The sustained speeds should be higher due to the battery size but I wouldn't personally want to risk modding the charging speed. Sounds like they made the insulation layers pretty small to get the capacity at the expense of charging rate.

My main concern is how well it sustains the speed and the temperatures (QC4 should be decent in that regard) because any maximum speed will drop off a cliff when it gets to 70-80% anyway.

Does it have 4.0 or 4.0+? I've seen some spec sheets saying it has 4.0+

It's really difficult to even find data on what the difference of those two are in real world scenarios. If I'm not mistaken the + version requires two PMICs (whereas it sounds like it was optional before) and I think the Zenfone might just have one. Asus themselves advertise 4 without the plus. If you ask me, Qualcomm should just have called it 5.0 to avoid the confusion especially because Qualcomm's own marketing material is very vague on this.

They added qc4, but it's more like qc3 with just 18w(9v 2A). I hope a kernel mod will allow the phone to get 27w which will charge the phone completely in approx 1h 30m to 1h 40m rather than 2h 15m with the 18w charger.

Whatcha think nerds?

The phone didn't charge any faster with my Black Shark 2's QC4+ 27W charger....I need to test that again.

I'd be surprised if the battery didn't get dangerously hot if it's done.

The separator wall of cathode and anode on a battery that can handle faster quick charging would need to be thicker.

Asus chose 5000mAh with a smaller separator to keep size down. In the same size, ASUS could have chosen, like many others have, to have gone with a ~4000mAh battery with a thicker wall to support 30W+ fast charging.

It comes down to trade-offs based on physics. I'm always game for experiments though :p

Hello, today, I bought this phone and I plugged it into charger for the first time. However, in my opinion, the phone warms up relatively high compared to my previos samsung S8+. Have you got any experience whit this? Maybe I am too much perceptive and it's normal. And maybe it is the difference between Quick Charge 2.0 (s8+) vs Quick Charge 4.0 (asus) :)

Mine warms up "as expected" I would say.. nothing surprising at least. Its going to be warmer or less warm depending on where in the charge cycle it is as well

27 w charge

Can we get faster charge while we use 27W adapter? Or will it break the device?

The difference between quick charge 4.0 vs 4+ is that 4+ is compatible with USB PD (power delivery) which is the fastest charging standard, its what i think OnePlus and Samsung use for their tech. 4.0+ was revealed in 2017 a year after 4.0. It's lame but unfortunately Asus's zenfone 6 current batches do not support 4+ (however 4+ charging is still backwards compatible with 4, 3, and 2.0, that's why when @MishaalRahman tried their QC4+ 27W charger it didn't charge any faster, it just downgrades to 4.0 charging speed)

there's a chance a refresh of Asus's zenfone 6 may happen with 4+ release. Doubt it..but who knows

4.0 is still supposed to charge faster than 3.0 but I personally don't really see that increase in charge speed. Could be because of the size of the battery but either way I'm still happy with it because the large battery just means less charging (for me personally) since I just mostly do google searches and text, and once in a while use snapchat/ig. Its the perfect phone for me, I bought it yesterday to replace my Pixel XL (gen 1).
