Why is superfast charging not available on premium phones? - General Questions and Answers

The Chinese smartphone brands with their dual cell systems have brought about revolutionary change in our charging experience. That coupled with their special emphasis on cooling inside the smartphone make these devices excellent for all types of use.
But when looking closer, I see that their latest (mind blowing) charging speeds are limited to their midrange models. Their premium flagships still come with a couple of years old charging speeds. Normally, any new feature is first launched with premium devices, which then trickles down to less expensive devices over time.
What are we supposed to understand from this?
1. Are midrange smartphones from these brands a testing ground for latest technologies?
2. Are such charging speeds indeed not good for long term battery health?
3. Are there risks with these superfast charging speeds that OEMs don't want to disclose?

Long-term battery preservation might be one possible reason.

They claim that the battery has well over 80% health even after 1500 charge cycles.
The first phone with 150W charging doesn't sacrifice battery health
realme has announced the GT Neo 3, packing 150W charging capabilities. Thankfully, this speed doesn't come at the expense of battery health.

There are similar and more impressive claims from all the brands. Are these claims not true then?

Fast charging is OEM dependent. Several standards exist: Quick Charge, USB Power Delivery PPS & USB Power Delivery.
On one side, brands are pursuing ever faster charge times with exceedingly high-power solutions. But to do this safely requires expensive battery and circuit components, more powerful chargers, and all too often proprietary standards. Even the best standards push beyond the boundaries of ideal battery temperatures. On the other side are the slower but more universal standards like USB Power Delivery. Their universal nature makes them slower to embrace the latest and greatest solutions to charge quickly, but they are very safe and run cooler than the competition.
AFAIK Qualcomm’s Quick Charge 5 is the fastest Quick Charge implementation to date and can match the fastest standards around. But at the same time, it can be a more conservative standard than other ultra-fast charging technologies making their way to the market and that’s not necessarily a bad thing. It augments the USB Power Delivery PPS standard with the potential for faster charging speeds, as seen by the Smartphone for Snapdragon Insiders and Xiaomi 120W implementations. More importantly, temperature and usage-aware capabilities can ensure that the battery stays below 40°C while fast charging, an important marker that other standards are too eager to ignore in pursuit of faster charge times.
Charging speeds compared​
Quick Charge 5: 42 minutes to full, 45W max, 38.7°C peak
Quick Charge 3: 67 minutes to full, 18W max, 34.5°C peak
USB Power Delivery PPS: 51 minutes to full, 35W max, 34.2°C peak
USB Power Delivery: 65 minutes to full, 18W max, 32.5°C peak
IMO the temperature measurements are more interesting. Quick Charge 5 is 5°C cooler in terms of max and average temps compared to the hottest competition. In addition to the temperature-aware charging power, Quick Charge 5 uses new, efficient power management ICs which can be used in dual-mode to help dissipate heat.
Charging Temperatures compared​
Quick Charge 5 65W (SFSI): 95mAh/min, 38.7°C peak, 34.7°C average
USB PD PPS 35W: 78mAh/min, 34.2°C peak, 31.7°C average
OnePlus 65W: 155mAh/min, 43.2°C peak, 39.7°C average
Xiaomi 120W (QC5): 214mAh/min, 43.8°C peak, 39.2°C average
Infinix 160W: 363mAh/min, 41.9°C peak, 37.9°C average
Resume:
Qualcomm's Quick Charge 5 is retaining compatibility with popular standards while adding in extra features for its partners to leverage in the pursuit of lower temperatures and/or faster speeds. So is Quick Charge 5 any good? Absolutely. In fact, it’s one of the better fast charging standards available in handsets right now. But remember, the exact implementation can vary quick a lot depending on the smartphone in question.

That's not true. The phones with superfast charging (100W and more) run just as cool as a Samsung, Pixel or Apple phone.
The reason for this is the presence of dual cells and how the technology has been implemented (heat is generated in the charger itself and not the phone).
USB PD and PPS have two benefits:
1. Universal compatibility which means you carry just one charger.
2. Reduce e-waste.
Without dual cells, it is almost impossible to match the charging speeds that we see in some of the phones today.

To my knowledge any Lithium-ion battery ( most phones have it today ) will heat-up during charging / discharging with high current.
This is due to internal resistance of the battery and heat produced is equivalent to current square by internal resistance value.
This internal resistance of the battery is not physical but is in the existence due to chemical composition of the battery.

1. Heat management is done better in the Chinese phones.
2. Not all current goes into one battery. Only half of it goes to each cell. This is why this is an excellent implementation.

1. I don't think that's necessarily the case but it does make up for an attractive marketing campaign for the mid rangers compared to the top end where other features are the stars. It's also likely that the top end market has chips that generate more heat, have wireless charging, etc which makes thermal dissipation a bit harder than your standard mid-ranger.
2. As you've quoted and as many other internal tests seem to indicate, across different Chinese OEMs, the tech has parallelly improved in the context of battery life and are on par, if not better than older generations.
3. Most symptoms should have shown up by now, seeing as the tech has been around for a while and in the least, over 10 million device "samples" with no major fiascos like the Samsung battery for that one model has happened yet.

This is true. No OEM has so far released a flagship phone with over 80 or 100W charging, even though they have midrangers that charge significantly faster. Most flagships are sticking to the 67W charging speeds.

The Mi 13 ultra does go upto 90W. The Iqoo 11 also hits the 100W+ mark, if I remember right. I believe Vivo's x90 series also hits 80W. There's a few that go higher but they don't get released global. I remember one model of Iqoo going to 200W but that was limited to China.
As someone who daily drives a 67W charging 5000Mah phone, it comfortably gives me 2+ days of battery with one charge to 90+ and maybe an occasional 5-15 min top up while I shower. It's probably the economical sweet spot, beyond which, you're spending a bit more on cables, charging bricks (given that most Chinese OEMs come with the charger), safety systems for the charging board, etc.. There's no real need to go higher, for most people. Not until we can get higher density batteries and can hit 7000-10000mah capacities on phones.
A respectable amount of folk, among my peers, who use flagships also tend to go for wireless charging, from what I've observed on the Android space. Could be part of the reason too.

Xiaomi has a few models that charge much faster, yet their ultra flagship charges at under 90W.
OnePlus, iQOO, Oppo, Vivo, Realme are all BBK brands and use the same charging technology. Yet the flagships don't come with the fastest charging speeds their tech is capable of.

That's not true. This is like Apple saying they will never make a phone as big as the Samsung Note. Today we barely see a phone smaller than that.

Wireless charging is terrible as of today. It is way too slow, inefficient and generates a lot more heat than wired charging. Unless this technology sees radical changes, superfast wired charging will be the preferred charging tech.

Extended power supply (plan).

Currently I have one of the 4 x AA battery extenders which copes not badly for the average day trip, but often means getting a set of extra batteries while travelling.
This can be a compete pain if I am travelling on a longer trip and and have a stop on a bus/train in some place where I was not staying long enough to buy currency, and they dont take cards.
So...
How about soldering a USB cable onto one of these (last row is the UK price).
6V 4.5Ah SLA L21AC 7.99
6V 10ah SLA UD07H 13.99
6V 12ah SLA UD08J 14.99
6V 7Ah SLA N33FR 1034 3.99
Remember the Ah rating is for 6v - so 5 times the equivalent of one 1.2v rechargeable AA or 4 times that of a 1.5v disposable.

The downside is they are obviously heavier, but have 3 times the capacity of standard rechargeables at under a kilo (but are small enough for the smallest side pocket on a rucsac).
The only downside is I dont know if they leak if battered.
Any suggestions/ideas?

Have you thought about Li Ion or NiMh batteries, they give better performance, last longer and more importantly are lighter. I use them on a converted electric mountain bike......
Another option might be something like this...
Freeloader Portable Solar Charger
http://www.maplin.co.uk/Search.aspx?menuno=11936&FromMenu=y&doy=1m2&MenuName=Portable Energy Source
Specs say can run a PDA for 22hrs on its internal battery which is recharged by solar panels.
Good luck
Thanks
I had looked at the freeloader, but it does not really hold enough power as the battery drains at an alarming rate on trains or coaches as it tries to find cells, and using the net, playing music, keeping the display on, videos eats the battery power to much to make a freeloader viable on long journeys.
Also - a free loader is not really viable to get a recharge on a plane, or train or bus if not at the sunny window side.
However, could you recommend any larger capacity NiMh or Li ion batteries that don't break the bank?
Cheers

I take your point on both counts.
The Li-ion battery packs that I use on the bike are 36V 2Ah Bosch cordless power tool batteries. Perhaps the power tool battery option might be suitible, as batteries/chargers are readily available and you could get a cordless drill as a bonus.........
Thanks/
I have a Bosch cordless hammer drill and the battery fits under around and to the front of the grip, but its massive, probably heavier than my motorcycle battery too. The charger for it is also pretty big.
How did you drop the voltage to make it work to charge in a USB range, as wont the internal resitance of the PDA vary vastly depending upon which functions it is performing?
I had noticed maplins did battery boxes for projects and had thought about either a 4x or 8x of C or D batteries or a 4x or 5x, C or D cheapo Maglite clone just to use for the battery storage tube.
However the downside with C or D batteries is most of the rechargable ones dont hold much over 3Ah unless going into the heavy price range, although these are starting to fall.
Did you find any specific battery with a good shape/weight/price/capacity?

Intocircuit® 2nd Gen Power Castle 13000mAh with SmartID™ Technology Review

Well I was looking for good battery pack and I have spent around 5 hours researching nearly 30 USB battery packs, eliminating models that were too expensive, too bulky, or too short on storage and I found the $35 IntoCircuit Power Castle 13,000 mAh is the USB power bank that most travelers should carry in their bags or briefcases. Some of pictures:
The IntoCircuit Power Castle is an amazing option for you as you can keep a smartphone running for a few days away from an outlet, and it can add hours to the life of a big tablet when you’re stuck on a long flight. Portable USB battery packs are a dime a dozen, but this one saves space, weight, time, and money—even if just a little bit of each.
It charges an iPhone5S almost 6 times, a Galaxy S5 over 3 times or an iPad Air once that’s much better if you compare with other alternative ones. One of key things for me about the product is stylish aluminum alloy shell with blue LCD display. The intelligent LED status bar indicates the current battery status and the current charging status will be on the LCD display as well which a great feature is for me and I am sure many other people also.
It this rate, with a staggering capacity of 13000 mAh, it is capable of delivering 3~8 full charges to most smart phones (Depending on your phone's battery capacity you will get best product at affordable price and you can forgot about charging as you don’t need to worry about your devices running out of power as you can run it with couple of days.
They build it with SmartID technology which not all chargers charge a device equally fast. Enhanced by the SmartID technology, the 2.1A smart USB port is capable of identifying a specific device, and thus ensuring maximum charging efficiency and speed. With SmartID, your charger "knows" your device and charges at full throttle.

Charging tech/cables? How much power can the pixel actually draw?

There's been tons of posts over the web about what kind of charger to buy for the pixel, but none of them really dive into the technical. I don't have the proper measuring tools to check current/voltage and would like to get some info. I'm wondering what kind of power the Pixel is able to handle in order to buy a charger. I really like anker but wondering if i need to branch out in order to get something that can deliver the proper power.
According to the Google Pixel spec sheet the charger is a 18W USB-C PD but google doesn't explicitly say anymore. There have been articles that say that the Pixel isn't QC3 compatible. There's also some info that the Pixel is using a propietary charging tech allowed within the PD standard. The PD standards allow up to 100W @ 20V which allows for 5A.
What kind of power can the pixel actually draw when fully open?
Also, side question as I can't seem to figure out the proper queries to get any answers. In regards to google's proprietary charging tech, is there a different between using the USB-A>USB-C cable vs the USB-C>USB-C cable using a power supply which can delivery more than enough power?

Isn't this one of those "everyone does it cause they heard it somewhere"? Isn't the rationale for slow charging due to termination current and thermal management to prevent degredation? If you can maintain ideal temperature ranges for the chemistry and proper transfer/movement of electrons, shouldn't charging at higher voltages and current (provided the cell can handle it) not be an issue? Which brings me to my original question. R&D and QC should've set tolerances which will dictate how much power the phone will pull. How much can the phone pull?

I cant properly answer your doubt i just recommend in base of my experience since I charge devices a lot because i try some time then I sell. Quickcharges decreases a lot the battery health, any kind of Quick charge. Teste with Samsung devices, ZTE axon 7, the Google pixel, Motorola devices, HTC 10, LG G5, and a lot of other devices. Now im waiting for my Oneplus 3T next week I will try the dash charge and a normal slow charge

quick charge 4.0

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?
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.

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
Did a very little test. on org charger and cable
Battery on 65% did give 7,5 Volts and 1,65-1,70 Amps
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+.

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).

General Well. This is a bit disappointing

S22 Ultra 45W vs S22 Ultra 25W vs S21 Ultra 25W charging test
wouldve expected it to charge much faster, especially when you consider the smaller battery.
Totally expected, 45W works just at lower temperatures and under 50% charge as it was back in the Note 10+ days. It's useful only when you are topping up on the go, for 0-100% it's almost the same

Well it is improved, it was downgraded 2 years ago to be fair and now is back to that state. It charges faster from 0% to 50% which is exactly how it used to work before. If you expected something different your expectations were wrong, don't know what to say. Even devices with very fast charge charge faster for the first half then slow down considerably. Samsung has always had a more conservative approach on charging after the Note 7 debacle, that's why I expected it to be managed like it was before.

The N10+ with the 25w brick will fast charge from 5-70% at the rate of 2%@min on its 4300mAh battery. Between 70-82% it may ramp down slightly, at 90% fast charging disengages.
This is dependent on battery start charging temperature, if too low or high fast charging will not engage, and battery condition. A 20% charge in 10 minutes isn't bad...
Fast charging is limited by heat buildup in the battery caused by internal resistance. The Li cell charging process is actually an endothermic reaction but is outweighed by the internal resistance generated heat.
I can see it being an issue for those that prioritize fast charging over battery longevity. I charge my device overnight and use a Chargie to regulate the charge to a maximum of 80% and limited to 8 watts. I'm not a power user and this method may not work for everyone.
Looks like they're using an older 45 watter. The new ones are the real 45 watts.

I doubt it. QC boosts the charge wattage by increasing the voltage; more volts less amps means less parasitic waste heat.
What's left to improve on the charging protocol side? They to improve the battery itself now for any meaningful performance improvements.
These manufacturers push the hype, the reviewers do too, then long after the release the truth finally comes out.
If you can wait a few months for the dust to settle you'll get a better idea of what to expect.
There is a new 45w charger, model EP-T4510XBEGGB. This one seems to work fine and not overheat.

I can see it being an issue for those that prioritize fast charging over battery longevity. I charge my device overnight and use a Chargie to regulate the charge to a maximum of 80% and limited to 8 watts. I'm not a power user and this method may not work for everyone.

Curious as to what your thoughts are regarding the Chargie since Samsung has now added the same charge up to 80% feature in Android 12 under device care. Is it now redundant?
