does mi 8 support mi 9 27 watt charger?

does mi 8 support mi 9 27 watt wall adapter from mi wireless charging bundle ? Then I want to know charging speed difference in mi 8 original charger vs mi 9 original charger.i was planning to mi 9 original charger for mi 9 but I saw mi 9 shiped with 18 watt charger same watt as my mi 8 adapter.so I want to know will the charging speed be the same or faster in mi 9 adapter?

almost September 2020, and I have news for you ...
I'm using google translator because I speak Spanish, sorry.
August 30, 2020, I have stable miui 12 from xiaomi.eu.
I have the charger of the xiaomi mi 9 (the one that comes with the wireless charging base) and the charging result is as follows:
using the antutu app it says the estimated capacity is 96%. In 65 minutes it has charged from 3% to 87%, it is not as fast as the xiaomi mi 9 (change my mi 9 for a mi 8 and money) but I think it is charging at more than 18 watts.
According to Antutu, the temperature of the battery is 36 degrees and that of the CPU is 39, but before these temperatures were between 45 and 50 degrees.
I wait for your comments about it.
Thank you.

Yes it does, and it should be faster compared to 18w one that came with mi 8. (27w>>18w)

Currently doing a test to compare it with the Mi 9. Have both the Mi 9 and Mi 8 and I have the 27W charger. Currently testing the Mi 8 from 55% to 100%, doing the same with the Mi 9. Will update on this.
EDIT: 27W doesnt work on the Mi 8. It took 55 minutes to get from 55% to 97%.

I have tested my Mi 8 with USB-PD 2.0 and 3.0 Chargers.
QC3 18W - charges about 1,5% per minute at 2400mAh
USB-PD 27W - charges about 2% per minute at 3200mAh
QC4 is based on USB-PD with a few super awesome secret features, if you ask Qualcomm.
What's needed is a USB-PD (or QC4) Charger that delivers 3A at 9V.
The Charger needs a USB-C Port and you need to use a USB-C to USB-C Cable without any adapters.
But don't get too happy right now. I present you the problems:
1. 27W Charging only is faster up to 60%. With a charge rate of 3200mAh at 60% the battery voltage reaches max and the phone needs to cut the charge rate down. At 70% the charge rate is down to QC3 18W at about 2400mAh.
2. I tested this in a room at 22°C. Battery temp at 24°C.
After about 10 minutes (20% charged), the Mi 8 is getting too hot with more than 34°C. The charge rate immediatly cuts down to 2700mAh. After a few minutes it cuts down to 2400mAh and we are back to 18W QC3.
I have to admit, I already tried to charge my Mi 8 with a tiny USB Fan cooling the phone while charging at 3200mAh.
Yes, that works, but.... I mean.... Cmon, I am not gonna start building me an aircooled charging station.
Btw: I am on Xiaomi.eu weekly Rom. Not sure about the official Rom, but isn't Xiaomi advertising QC4 for the Mi 8?

With 27 watt adapter , charging speed still suck like 18 watt adapter:3 but device is cooler and it's like no heating at all. That's the only difference.

Well, QC3, QC4+ and USB-PD, they all charge at 9V.
QC4+ and USB-PD are just able to charge with about 30% more amps.
The high temperatures, when charging, results mostly of the transition of the 9V the charger has to send over the USB-Cable, in order to keep the amps low enough in the cable, to a max of 4.4V the battery needs.
This causes the battery to heat up, exactly like high CPU temperatures heat up the battery. Its a small device, thats all.
What I want to say is:
You are wrong. 27W chargers do charge faster, about 30% faster.
You charged from >55% to 100%, of course there is no advantage in comparison to a 18W charger.
You are right. Charging speed still sucks at 27W chargers.
I really appreciate the 27W charging. During the day, when my mi 8 is down to 30%, I can charge it for 10 minutes to get back to 50%. Thats a lot and most of the time it's enough for the rest of the day.
Every night, I charge my mi 8 with a 5V 1A charger. No need for fast charging there.

I came here to say pretty much the same thing, you will only see the benefit if your battery is low. So charging from 20% to 60% will show some increase in charge speed, from the there the heat protection mechanism via the kernel will slow down the charge rate. Its truly not a good idea to charge your phone too fast, as heat will decay the battery much faster.
Although it's nice to have the option if you are in a hurry. My charger is next to a large fan ( works fine, stays cool)
BTW, here is a great informational article concerning prolonging the battery and avoiding heat: https://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries

The Mi 9 charges in around 55 minutes from 0% to 100%, the Mi 8 took 55 minutes to get from 55 to 97%.
Just wanting to say that it just isnt as fast as the Mi 9. The 27W charger does charge a bit faster, but only upto around 50%.

0% to 100% in 55 minutes is impressive. Although just from the numbers, with no personal experience, it's hard to believe. This would be a charge rate of at least 4000mA.
Can you do me a favour?
1. Can you try charging your Mi 9 with a QC3 18W charger and tell us how long it takes from 0% to 100%?
2. Can you try this app: https://play.google.com/store/apps/details?id=com.gombosdev.ampere&hl=en_US

I hope you did not get the feeling that I was assuming that you were lying about the charge time.
Maybe you found out your charge times weren't what you first think there were and that's why you did not answer to this day.
Maybe I was wrong not believing you.
Everybody makes mistakes, it doesn't count who made them. What really counts is to make mistakes in the first place. I don't know any other way to improve.
Long story short: I want to apologize. Please come back and tell us about the charge time of the mi 9 with the mi 8 charger in comparison to the mi 9 charger. That would make this thread complete.
I am really interested if the mi 9 got any advantages in it's charging hardware. I can't find anything about it but it seems that the mi 9 really charges a bit faster than the mi 8. Looks like there are improvements made in the mi 9.

Of course!

i prefer the 18 w fast charged since it wont degrade the battery as fast as 30 w fast charger. of course a 6000 mah is more difficult to degrade, but the life span will be better with 18w charger
the tencent edition 8/128 is a best buy.. not worth the global 12/512gb . only it has little more bands, all glass body, some new accessory and fast charged. reccomended only for people that use more than 128gb.
128gb is more than enough for me and an almost 1000$ 512gb global model is not giustified!

Proper fast charging shouldn't degrade a battery any faster than normal charging, as long as it doesn't cause the battery to heat up more than normal or charge to a higher finished voltage than normal. What degrades a battery is charging it to 100% all the time, because that last 5 to 10 percent of the charge is up in the 4.15 to 4.2+ volts per cell, which causes the damage that we see as degradation. If you limited the charge to 80%, or even 90% you'd get a MUCH slower degradation of the battery.

And what's nice about the phone is that it gives you a way to mitigate this right from settings. Go to Settings, Battery, PowerMaster, Battery Care. Here you can set times for dynamic charging between hours X and Y to get to 100% instead of as fast as you can. Mine is set 10 pm to 7 am for now.

Any 30W third party compatible?

Using the original supplied battery and cable takes around 4 hours or more, any suggestion???
Why it's taking over 4 hours?? Any way to fix?

It takes 4 hours with the phone off or on. If it's on make sure that scheduled charging isn't activated during the period you try to charge the phone.
If non of what I suggested is useful, it's better you take your device to ASUS service center.

There is a problem with your device battery mate either this or your charger is the issue. From 50% to 100% it shouldn't take more than 1 hour and that's with the default charger that comes with the device itself 18W. Try to charge the device with another charger and compare. Otherwise I advice you to taking it to the service center.

Thank you for your advice, I will try charging using my Sony Xperia 1 charger & see if it makes any difference.
Otherwise the battery holds charge very well. I will update you shortly as I've only had the device for 3 days...

I will also order this and see if it helps:
JuicEBitz® 25W 3 Port USB FAST QC3.0 Mains Charger Adapter +
It should provide me with the fastest supported charge. I'll order it next week & once tested I will report back.
---------- Post added at 09:21 PM ---------- Previous post was at 08:53 PM ----------
I already have an update and know what the problem is.
Around 30 minutes back, I had 60% battery. Just now I unplugged it and it was 96%
I used original Sony Xperia 1 18w charger and cable. This means that there is an issue with the supplied Asus charger, it is charging very slowly. The 18W Sony charger is charging much faster than the 30W Asus...

Anyway to charge only to 80% in software? With a 6000 mAh battery, I don't really need to charge to full if I can increase longevity of the battery life.

Doubt about fast charge

Hello friends. I've just bought a S20 FE Snapdragon to my wife but I have a doubt about fast charge.
My 18W Quick Charge 3.0 and my 27W Quick Charge 4.0 don't work as I wished. They just do a normal charge.
I've read that Exynos Edition uses Samsung 25W charger, but what about the Snapdragon edition? Does it use this 25W charger? What about the 45W charger?
Thank you guys.

yes it supports up to 25watt charging, you have to turn it on yourself if it's not activated.
battery and device care / battery / more battery settings / enable fast charge

Thank you for the reply. I've search it and it's enabled by default. I tried an Aukey Quick Charge 3.0 18 W and worked. It says it's fast charge. It's not stellar but way better than 2+ hours.

I didn't try the 15w charger that comes in the box. What I think that was weird was my 27W Xiaomi charger charging with the time beyond two hours until it finishes.
Do you know if the 45W charger works?

nothing above 25watts will work any faster, the maximum current draw is 25watts if it works at all. not all fast chargers do work properly, that might explain your Xiaomi 2hrs plus.
the phone and the charger need to be able to communicate with each other / be running on the same standard.

True. I just bought a Samsung 25W super fast charge to my Snapdragon 865 and worked. I'll buy one for my father that uses an Exynos SoC too. It's sad to spend money with something like that.

I use the Samsung 20 w brick. When fast charging it get about 2%@minute.
Fast charging will not engage if the start temperature is too low or high.
If the battery has failed*.
Fast charging ramps down at around 80% to slow charging or if battery temperature goes to high. If temperature continues to climb above 102 F or so it will disengage entirely and end that charge cycle.
After 90% the charge rate crawls at as little as 1%@2 minutes.
* check for rear cover bulging. A battery can fail at any time but it's more likely to happen in an older degraded cell. Failures can happen fast, replaced asap, like that same day, if this happens. It can destroy the phone.

How To Guide How to extend your battery life (Xiaomi Scammed Us)

THROW YOUR 120W CHARGER AWAY.​
Get a charger for around 65W.​
Get a decently good brand. ( I'm using Anker, 65W Mi Charger is also good. )​
Anything below 30W would be too slow to charge your phone. Not really practical.​
Personally tested a 10W charger, did not work out for me as it doesn't give me the same battery performance.​
In my opinion, Xiaomi played us on this one. The 120W charger is a marketing gimmick. I don't think it charges the phone to 100% even though it shows 100%. Either that, or it messes with the battery calibration. As soon as I charge with a 65W charger, the battery goes back to performing properly. By that I mean, lasts me the entire day, and I still have 35-40% remaining the next day on medium usage like maps, streaming. On heavy usage, it still gives me great battery.
I'm 100% sure, you will notice the difference if you switch away from 120W charger as it will drastically extend the battery.
If you have already experienced the difference or made the switch, please do share your experience. On the stock xiaomi charger provided with the phone, the battery life is really terrible, the same usage gets me barely to the end of the day.
If you're still not satisfied by the drastic difference made by the charger only.

How to increase the battery life of the Xiaomi 11T / T Pro
Hello guys, I want to tell you about the adjustments that I have made to my Xiaomi 11T Pro and that have improved battery consumption, keeping the refresh rate of the screen at 120Hz. I would appreciate if you could tell me how it went...
forum.xda-developers.com

It will be simply because it is a fast charger, incredibly fast, and you can't completely charge lithium batteries fast, there is always a slow end stage that will take an hour or more regardless of how many watts the charger is. The last top off stage, or saturation stage on lithium cells needs by definition to take time and will charge at a lower current and it has to be slower.
They are showing 100% on fast charging, but that's only the bulk charge capacity with a lot of the saturation stage not done, so you don't get full capacity. The 100% indicator is saying you've charged as much as you can fast, but it might only be 70% actually full. If it is left on the charger, it will likely wait until the temperature has dropped then continue for an hour or so completing the saturation charge, all while still indicating charging is complete, but if you remove it from the charger the moment it hits 100%, then it's not the same 100% you'd get by leaving for a couple of hours.
If they indicated 100% correctly as being as charged as it can be, it will take 20 minutes on fast charge plus an hour or two for the saturation stage to be done, so doesn't quite sell as well!
Xiaomi are cheating somewhat by saying 0 to 100% in x time on fast charge, as the definition of 100% when fast charging is changed.
Personally I just charge over night at 5 watt, better for the battery and you get full capacity.

It will be simply because it is a fast charger, incredibly fast, and you can't completely charge lithium batteries fast, there is always a slow end stage that will take an hour or more regardless of how many watts the charger is. The last top off stage, or saturation stage on lithium cells needs by definition to take time and will charge at a lower current and it has to be slower.
They are showing 100% on fast charging, but that's only the bulk charge capacity with a lot of the saturation stage not done, so you don't get full capacity.

Great insight, they should have mentioned it in a different way instead of saying it's 100% charged. But then that ain't gonna earn them any bucks.
Are you getting a good battery life on 5W? As when i was using the 10W charger and use the phone at the same time it would take forever to charge. And the battery sot wasn't as good as well compared to 65W sot for similar usage.

I also use 10w (5v 2A) and can get for about 8h of sot, charging time is in my case takes about 2:20h from 17-100%Its not that bad, and i prefere slow charging time anyway, i only use 120w when in hurry

If you are using the phone at the same time as charging, you are of course using a chunk of that 5 watts to power the phone, so whilst your battery may not be discharging, there isn't much left over to charge it up.
I always charge overnight as I easily get a day if not a few days from a single charge as I'm not using it much currently as working from home, but if you need to top up during the day whilst still perhaps using it, you would need a charger with a bit more wattage.
Also note that whilst it may say 100% charged, that could represent anywhere from say 95% to 100% actual charge. This is because lithium cells can not be trickle charged, so when charging it will get to being a full capacity, then charging stops, the battery is allowed to discharge several percent before automatically being topped up again, and the cycle continues. So depending on where in that cycle you take the phone of charge, you might be really at 100%, but could equally be at 95%. Because people would complain if the true charge status was shown, i.e. people leave the phone on charge all night and its still only showing 95% in the morning simply because it's on the discharge stage of the discharge/top up cycle when they look at it, they would complain, so 100% is shown from say anywhere between 95% and 100% of real charge state. This applies to all devices. It is why sometimes you take your phone of charge at 100% and it seems to stay at 100% for some time, and other times it starts going down soon after you've unplug it from the charger. Google on their Pixels have an adaptive battery setting and use the alarm clock you've set to know when you are getting up, so they make sure they time that cycle so that you get the phone at a real 100% capacity.

Good thread fellas. Yeah 120w it's just a thing you should use when there's not another option or your in a real rush. And by using it your battery calibration might get confused.
It's as the OP mentioned, with 120w you can feel that your battery life is shorter than charging with lower wattages.
IMO and experience I calibrated my phone's battery (drained it to 0 let it turn off , leave it unattended for around 10 min, then charge it with a 10w while still turned off if possible. And leave it charging 1h more after it says 100%) and b ayer doing so my 11t pro finally became the 2-day phone it should have been from day one.
I personally prefer to charge mine with a 18w (1h20min) or a 22.5w (1h) during the day. 10w it's just for overnight, it's just to long 2h40min or more.

This might be the reason why Samsung nor Apple has not yet jump into bandwagon of 100w-ish charging. Even not to 65w. It just my hunch though. Still, 100w-ish charging might be life changing in certain situation. And if I recall correctly, the most ideal percentage to charge Li-On is around 80-ish, that might the actual percentage that we get if we charge to 100% with 100w-ish charger.

To be honest i tried 33w charger and 120w charger and battery performance for me is the same(4.5sot + 6 background yt music)
The thing is when u use 120W charger and battery go 100% you have to let it charge 5-10 min more because is not fully charged.
You can check with app called ampere(download from playstore)

Please try a 65W charger from xiaomi or anker, i guarantee you the difference. Sot also depends on the usage, but there will surely be a drastic increase in the battery capacity.
And i completely agree to your point on trickle charging. But unfortunately, it does not justify the 4 hrs sot difference im getting after charging my phone through different chargers. 65W gives me 8 hours, whereas 120W full charge gives me around 4 hours.
I feel xiaomi really just did this as a marketing gimmick and did a half hazard job at it.

Like i previously mentioned as well in the above post, trickle charging or that 5-10% of charge shouldnt make the difference im experiencing after switching chargers. 4 hours sot difference is no joke. Its literally half battery capacity.
I love the phone, but Xiaomi really messed around with us on this.

Unfortunately i don't have a 65w charger :/
I get 4.5 sot because i also use yt music for 6-7 hours in background + 5g all dhe time.
The problem i noticed is that when i use my phone after charging my battery gives me good sot (5 hour non stop gaming mlbb and still have 25% left). But if i charge at night and use the phone the next day the battery drain really fast (that's why i charge every morning before i leave home).
I'm not really happy with battery life to be honest but im really happy with charging speed
+ How you guys get sot 8hrs?. I never couldn't do that with my phones( old device k20 pro average 5hrs sot)

Even after switching away from 120W charger, if you're not seeing a drastic difference, then i recommend changing the chargers to something similar to what i own (anker) about 65W or a mi charger 65W (official). Because i personally experienced the huge battery life change, and i know this phone can give a 1.5 day battery life on medium usage. On heavy usage it lasts me easily the entire day (8hours sot easy). But usage may vary. And when i was using 120W charger, it was giving me 4hours sot, with the same usage. So i know, the phone has the capacity to do it.
Maybe it could be a non branded charger issue? I'm not sure. It should show quick charging when charging via the different charger as well that way you know its getting the juice it requires.

Rocking a Xiaomi 67W charger and so far not much difference. I'm using the phone out of the box, I am not switching back to 60hz since whats the point of buying it if you wont use 120hz. Lets see after a few more cycles.
EDIT: After using this 67W for 2 days now, battery life is the same. IT might not be the charger but going back to 60 Hz might be the reason some ppl had improved battery life. I will return back to 120W since I prefer the ultra fast charging while the phone stays cool at the same time (mine is at 40-41 degrees C and it charges around 20 minutes)
EDIT 2: Tried 60hz for a day, since I was out with family, it noticeably improved battery life even though I charged with the 120W adapter. Hopefully Xiaomi adds a dynamicswitch feature for us soon or a 90hz option

I tried using my phone on 120hz for a day or two, i get like an hour less compared to 60hz i find a major difference in battery even with 120hz enabled.
Not sure why. But if it works, it works.
Also just to clear my experience, i never use this phone on 120hz, even when i initially was using the 120w charger. It has always been set to 60hz for me, as i like to save battery wherever i can.

Update: Using accubattery, when my phone reached 100%, its still taking in current around 1500-2000mah range (around 10-15w) and its trickle charging the battery. The estimated capacity when reaching 100% is around 2200 mah(times 2 since our phone is a dual cell battery) then letting it trickle charge for a few minutes (an extra 10) made the capacity to 2550(which is around 5100 mah) and by doing so I am easily getting 6-7 hr sot on 120HZ. It may be a marketing trick to reach 100% in an instant but leave it plugged in for an extra 10 mins or so to get more screen on time.

quite great battery life

Amazing!
MIUI 13 by any chance?

I am on miui 13 official, had heavy battery drain on miui12.5, disabled miui optimizations and now everything is good
Edit: apparently the program that handles battery changed after disabling miui optimizations, maybe it's a bug related issue

Question Battery charging

Whatat is the best way to charge 11T pro, from 10% to 100% or during the days a couple times , charge to 60% , charge to 80% depends how much time you have to prepare when you go outside??

You want to keep the battery as close to 50% as possible. The general rule of thumb is to keep your charge between 80% and 20%.

I read somwere that this our charger and charger of 62 wat difrently charges battery, this 120wat charge it so fast that the battery dont have time to fully charged but with 62 wat charger it takes a litlle longer and battery can least more than a day, its a very big diference adn people on Reddit confirming that ..

I don't know and I don't care. You're still replacing it in a couple of years so why bother?

Performing the test with a 20w charger and the 120w charger, the battery time estimate is more or less the same but after similar use ,the use time with a 120w lasts less than that of the 20w.

I don't think that the "estimated" time will change after 1-2 charges. I think it takes into account many previous charges. (that I guess you did with 120W)

Absolutely not, it is obvious that for physical reasons, the 120w charger remains a charger for people in a hurry and that the best charge for this type of battery remains the low and long charge.

I wouldn't be so sure my friend.
In Another Samsung phone with removable , I have a really old battery that lasts like an hour or two and a brand new original that lasts 36 hours.
When I had used the good battery (and get an estimated remaining time of let's say 28h) when I switch to the old battery the E.R.T. is still 20+ hours. Nevertheless it runs out in a couple of hours.
Same with cars and consumption.
