Mi5 and QC with original charger+cable - What values expected in apps like Ampere?

Hello everyone,
Ever since I got this Mi5 (125GB 4GB version) I've been trying everything I can so see it its behavior matches what is advertised. I should start off by saying so far so good.
Coming from a Moto X xt1092 I was used to some sort of indication that I was plugged to a QC enabled charger, not just a regular one. On this Mi5, however, and keep in mind that I'm under Lineage OS, I have no indication. I can count the minutes it takes to fill up a dead battery or maybe just 50% percent of it, but I'd like a sure and bullet proof indication. Also keep in mind that I'm using the original charger and cable - said charger that has the QC symbol on it.
Reading other threads, I noticed some posters were advised apps like Ampere - which I installed. Now, what kind of values should I expect from the app when charging? As of now, it hits a maximum of 1610 mA. What should I be looking at and what are the cutoffs above which I can be sure it's quick charging, as opposed to just regular charging?
Thank you in advance.
Added info: just set it to charge at 4%. 38 min later it was at 29%. It seems to me that 25% in 38 min is below QC 3 or even 2 standard (as it is often said that despite the mi5 being QC3 compatible, the original charger is QC2).

So, any chance one of you mi 5 owners can grab that app and give me some reference numbers? Just so I know for sure that I need to try and get a refund for the charger the phone shipped with.

4.1260 V
2860 mA

Thank you.
Yeah that's way higher higher​ than what I'm getting. Also, under technology I have "Li-ion", and a much lower Voltage.
Weird.
Something is definitely up.

the brick you get in the box is qc2. The device supports qc3 though and if the device is hot it will go upto 1610ma only buy a qc 3 brick roughly your charge should be done in 1hr 15-1hr 30 minutes

I knew the charger was qc2, I just thought it would go higher than 1610, which is exactly the top mA registered. Thanks for that info - I guess there's nothing wrong with it.
I have a qc3 charger on the way too.

The shipped charger has max current of 2.5A and indeed, during the first 10% ampere shows value near that (23XX mA on my phone). It will then gradually decrease down to 0.01A when the capacity is above 95%. Using real QC 3.0 charger (I have both Tronsmart and Aukey), the first 10% it can reach 28XX mA. The ending is similar, though.

I use the stock charger and cable that came in the box. I bought it here in macedonia. But i dont have an idea for wich market it is destined. I can confirm that it charges the phone to 85-90% in less than an hour, then it gets slow as stated above

Yeah I don't get those times, not even nearly. As you can see from the screen shot it took about two hours, most of which with screen off and no activity.

Do you have the same oem charger that i pictured above?

try to use different cable or different charger like aukey or tronsmart..
FYI original charger which support QC 3.0 Just MDY 08-EH

No only mainland china mi5 ships with QC 3 other regions where mi5 is sold only gets qc2 charger Google it if you want

Well mine was bought in Macedonia (south east europe) and i got a qc 3.0. indeed it is not with a local standard socket so i use a smalla dapter for the plug, but the point is that it depends to wich parts of the world xiaomi "officially" export, and to wich parts of the worlds (most of them) local companies undertake an adventure to import a batch of several hundred or thousands units from xiaomi, thus meaning destined for local chinese market

Yes, the exact same. But as that's not an European plug, I wonder if that's why I get different performance - it came with an adaptor.
I'm awaiting a new cable and charger in the mail soon that should clear it up.

Damn.
This is original charger and cable? Any US to EU adapter by any chance?
Here's hoping it's not lineage os related.

It's stock charger bro.

Using the stock charger, a qc2.0 one (given with the international version of MI5), I get about 2200ma - 2300ma. I haven't tried a quick charger 3.0. However, check your kernel as well. The stock one of Lineage OS have an issue with quick charging, working once only after boot. I use DragonXia kernel and the qc works all the time.
To check if it is kernel issue, shutdown your phone and them connect the charger. I will start charging but using the recovery/boot kernel based on marshmallow, which (at least for me) hasn't got the issue of qc. Observe then the speed of charge and report.

Tested a mi5, same variant as mine, just today, with same lineage OS version. Also original charger and cable. Values are the same as yours, well above mine.
However, my original cable is defective, and has been refunded as the phone wasn't being recognized on the pc (which was a problem when flashing roms). A new one is in the mail, and in a day or two I suspect it'll solve the issue. I'll let you know.

Keep in mind apps are a bad way to check for QC capability.
My xiaomi stock charger puts out 1,8A @ 6V with 70% full battery(the higest current is being used between 20-50%, i'll try that later on)
Ampere only shows battery voltage(3,7-4,2V) instead of charging voltage and the ampere display is way off actual current

Original Charger vs Quick Charger 3.0

Original charger hits 1700mA while Quick Charger 3.0 hits 2300mA. Screenshots below. I'd like to know if anyone else has done a similar test so we can compare results. I bought a (supposedly) Quick Charger 3.0. The results are obviously better but I'm not sure if its supposed to be higher or not.

SD660 can even do Quick Charge 4, but for Mi A2 officially only in india.

Global version might need a patch.

This this means that we can use Quick Charger 3.0 or 4.0 without harming phone's battery?

Mi A2 has official support for QC 3.0 (and 4.0 in India only). Of course you can use it without any harm.

That was my doubt too, the global My A2, perfectly compatible with QC3.0, without causing any damage to the equipment, that was my fear, but now ready, subject clarified ... I use QC3.0 Lenuo.

Exactly! i really don't know how that works.. Does that mean that the original charger is somehow a quick charger?

Empirical evidence suggests that Oreo seems to show "charging rapidly" anytime amperage is above 1 amp or so, it has nothing to do with using a quick charger or the original brick supporting quick charge.

No guys. I found:
0 - 999 mA = charging slowly
1000 - 1499 mA = charging
>> 1500 = Charging rapidly
Not sure if MiA2 use the same parameter.

Nice, I was gonna say 1500 cause that was kind of what I remembered but wasn't totally sure. 1.5A is typically rapid enough to charge with relative speed even while the device is in use which is probably why that was picked. I agree that they should probably provide a reading above 2A to signify quick charging as "charging rapidly" is definitely confusing.

OnePlus warp charge comparability ?

Does anyone know/Think that the OnePlus warp or warp charge 30 power adapter would work with the Realme X2 pro ?
I know it will not be as fast but I can get one for free from oneplus referral points and it would be UK 3 pin.
Realme says the phone is compatible with other charging technologies like quick charge.
I will test it with my Oneplus 6T charger once I receive the phone and of it works I will get another one from Oneplus

I need a UK adapter but have purchased one so will be using the vooc charge occasionally when needed,
As these batteries only have certain number of cycles I would prefer to charge the phone with something else on a daily basis.
I'm interested in maintaining the battery for a few years so would like to keep it somewhere in the 45 to 85 range which has worked well for me with all recent phones I've owned

I hope you're right, because i haven't understand if supervooc is good or bad for this phone.
So, you can buy any qc 3.0, i like Aukey

I don't think it's necessarly bad for the phone but I don't trust it either. I have read in many reports it is quick charge compatable and I've heard that the OnePlus dash charge has worked also. I personally have no issue with these slower charge speeds and actually prefer them.
I will use the 50 watt in times I need it otherwise I will use the other ones

There is 2 batteries in the X2 pro and from what I understand the 50w is split between them both.... So it's more like 25w per battery as apposed to a single battery taking a full 50w. I personally wouldn't worry about it and enjoy the rapid charging.

Not necessarily, whether there's two or one battery,each will need to be maintained to some degree or they will degrade

I always charge it over the night with an old and slow adapter from my LG g4, if I need a boost, I use the vooc One, did the same with the previous huawei mate 10 pro for 2 years and battery is still as good as the first day [emoji6]

Do you have a result of charging speed in AccuBattery for example? Could you also do a test when your phone battery is low? At such high battery the charging speed will be slow, and it will show less Amps than the maximum (and it should definitely show higher than than with the Vooc speeds). I'm not saying I don't believe you lol, but the phone might be tricking both of us showing Vooc, when it actually doesn't utilise Vooc speed.

Lol I respect that, but all I'm asking is when your battery is low next time and you connect it to the charger, just check the amps again in Ampere. And perhaps check for how long it charged in Accubattery, if you have it installed.

If your battery capacity is properly set in Accubattery, then it seems that it's charging as you would expect from the Warp charge. Just that the Amps seem low, but who knows. In the "history" tab it should show the exact duration. Thanks for testing :good:

No expert myself but it seems to be charging just as fast as my old 6T though this is a warp charge 30t charger I got off OnePlus using voucher Codes,
My 50 watt charger is the EU one and I use a eu to UK adapter with no issue.
Don't think I'll use the warp charge again as it's noticeably slower than the 50 watt,
Though the warp charge is still good 27 to 85 in 33 mins
Would probably be around 12 mins on the 50 watt

Yep that seems good. Nice job :good:

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.

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.
