Taken from GSMArena article:
"Note: a typical lithium battery works at around 3.8V so pushing a higher voltage to the phone requires hardware inside the phone to step down the voltage. This creates a good deal of heat, not to mention that it’s inefficient.
This is why all these standards are trying to keep the voltage down. At high power levels a different problem rears its head - the thin wires inside USB cables can't carry much power. USB-C has four power/ground wires, but even then there comes a point where the only way to raise the power requires raising the voltage."
I think someone will correct ur smartass knowledge, the reason why I keep quiet.
But, no one do it, so I will do it myself.

They're catching up a bit, but remain well behind Oppo and Huawei in the fast charging R&D war.

I get 2 days heavy usage out of my Mate 20 Pro with 40W charging and when I do charge it takes very little time.

You are completely wrong. And internally allow batteries to charge several independent cells groups in parallel helps to charge them faster.

What makes Qualcomm's QC 2.0/3.0/4.0+ tech inefficient?
Because they focused on increasing the Voltage (2A 9V), and keep the Ampere, which resulted in the over heat when charging.
This time, Xiaomi's approach is a BIT different; they increase the Voltage to the safe limit (20v) while decreasing the Ampere to the value used in 2010's charger (1.35A is the standard value of chargers at that time) to make the charging less hot (the energy wasted on the heat when charging might be reduced to significant level from this approach)

This only works if we have like 2 or 3 battery but that lead to another problem. Small butteries are much more lean toward degradation also there is almost no phone with more than 1 battery(battery cell)
about property charger: i didn't mean the life time of charger itself!
i was more thinking about you need to carry more than 1 charger because one of your phones wont charge with other ones charger(personally dual carry one note 8 and one BB passport and tho only thing i carry beside note 8 charger it's passport cable)
so the only hassle would be having 2 charger which are non compatible

Who gives a flying turd about the charging speeds, people want to stay away for charging as long as possible. There're phones with over 10000 mAh batteries which have about the same dimensions as these trendy 6" paddles but they're still it's a an incredible innovation and peak of human progress when we get 4k mAh in them

This is going to be one of the main reasons why fast charging depletes phones' batteries faster, because of poor hardware designs and executions.
They could just make the battery capable of having multiple connection points from the power source in order to lessen the need of a higher power charging solution.
In terms of propietary charger, I think it's just very easy to do so. The user just needs enough care of the product and it will do just fine. My sister's iPhone 7 Plus is already 2 years old and she's still using the same exact original charger that came with the phone inside the box, though her battery is pretty much critical already because of bad habit.

joe, 29 Jan 2019in size of tv set or normal size phone? maybe some older gu... moreSorry my dear user but I have to disagree,
even though the inches are increasing when you look paper specifications in reality mobile phones are pretty much the same. These newer resolutions get the blame and even though some 'TV-Controllerfication' is acceptable some implementations like the newest from Sony are disgusting and someone needs to stop them before it's too late and becomes a trend.
However as I said I consider their usual size around the one that we were used to the last many (3-4) years. Just compare Note 4 5.7in vs Xiaomi Mi 8 6.2in
even though you would expect Xiaomi to be much bigger, it isnt, its more compact.
But anyway this is just my opinion and currently I am looking for something between 6.5 og 6.7 with minimal bezels, so I guess there are more out there like me since the companies are working a bit around that number ( size )

in size of tv set or normal size phone? maybe some older guys remember "gangmembers" on street walking music center on their shoulders? looks like smartphone trend is moving in direction people hanging around tv set on their hands :)

Well this is getting interesting maybe it will be Mi Mix 4 or Mi Max 4 of 2019. Well lets see.

Oppo's SuperVOOC is still superior, due to its structure being much more battery health-friendly and will cause much less heating problems
5V/10A is much better than 20V/1.35A, because the flow of current can be controlled easily by the phone itself, so it will be able to keep itself cool throughout the charging period.
