Fast charging using normal adapter? - Xiaomi Redmi Note 7 Pro Questions & Answers

As we all know, the charger xiaomi provided in the box does not support fast charging, although it is quite good. For fast charging we have to use different adapters or powerbanks that support it.
Yesterday when I was using my normal charger, it suddenly showed quick charge and two lightning symbols in the top right corner, which indicates fast charging, that I usually get when using my mi powerbank.
First I thought it was a software flaw but sure enough, my phone was charging at a much faster rate and was heating up similar to when I charge using powerbank.
Unfortunately when I removed the charger and reinserted it, the phone charges at it's normal rate, and I've been unsuccessfully trying to repeat it but it's not happening.
My device is completely unmodified, stock unrooted rom and bootloader locked.
I think this means that the normal adapter might be capable of fast charging but xiaomi has disabled it, something worth looking into.
Also I know the phone charges quite fast below 50%, I saw this effect while phone was at 69% and reached 72% in barely 3 minutes or something.
Unfortunately I did not have the presence of mind to take photos as proof.

first of all if you are using charger which comes in box with the phone, its not a fast charger its only 5V2A.
2nd it can't charge at pace compared to fast chargers as it can only provide 2A at max or it may be faulty
3rd it may be software bug just showing quick charge
and in the end you said it charged from 69 to 72 in 3 min. i can say its not fast charging because my charger 5V2A which came in box also charges at same speed you are saying. it normally takes around 1 min for 1% increase but depends on various factors like load being used currently by the phone.
sometimes when data is off or battery saver os on it charges more quickly as consumption is also less so it charges fast.

It was 2% in one minute, I've attached a ss from telegram group of violet where I reported this for proof. My data and wifi were on, and I've enabled always switch on data for faster switching in developer settings.
Even now it's currently happening, but the rate is very slow, I think it's probably a software bug like you say, any idea why this is happening?
Edit 1: That Telegram ss is from the day where I first created this thread, not today.

i know the time is different but why didn't it increased in screenshots you uploaded the time already changed in both of them but battery remains same 69%. its showing fast charging but its not working I guess
plus maybe your battery health is not good.

Depletion time on battery - turbo charged vs normal charger

This is a poll. Again, its your normal day use.
My finding so far: my battery will deplete faster if its charged with turbo charger. I have two MXPE's : one for me and one for my wife. I charged hers to 100% using Turbo and mine with normal charger. Same settings for Moto display, same brightness level and pretty much similar usages. In fact, I use my phone more than her because I am somewhat more active on whatsapp. Her phone deleted faster than mine.
Have you guys noticed any difference in this respect? I am thinking I am going to use normal charger for night and use turbo charger only in a pinch.
I've read this assertion elsewhere too - that any quick charged phone depletes battery faster. Actually I charged my battery with my old slow charger last night to see if I'd lose less today. Subjectively (because my usage isn't really consistent), it seems like maybe the phone is discharging more slowly...
Could be a possibility but i have my lg g3 that i used for a year.. Co pairing my faily usage i get about the same hours of ost.
I think hers may be going down faster maybe because of the background apps or the ost shes using? U cant say ur using the same apps unless u tried them both for ur self..
I know this is the case. I have a Tablet and Phone when I charge them with slightly higher power chargers they deplete at a much faster rate. And when I charge with the slower charger they hold a charge much longer.
(Although bare in mind I'm talking about non Quick Charging devices so maybe that plays a huge part lol but I dont use Quick Chargers on them just slightly faster chargers when I have no choice.)

For those of you that have noticed faster battery loss after using the quick charge have you tried the non quick charger for a night charge than at a random time used the car quick charge charger? Does the time differ at all than?
I think this needs more testing. I need to do the test on my phone alone on 2 consecutive working days.
I don't understand what the logic behind this theory would be. Just because one reviewer mentioned it all of a sudden its a thing? Not trying to argue just don't understand the logic. The battery/phone don't heat while turbo charging so why would battery deplete faster?

A lot of people report the device gets hot when turbo charging. By the nature of the forcing of charge and the small footprint, how could it not get somewhat hot? I do not use fast charging on my Pure due to this.

Charging fast is bad for the battery, so it only makes sense for her not to last as long.
My wife wears down faster when I quick charge her. I only do it when I need her for short bursts.

As I understand turbo change. The phone only utilizes turbo charge for the 0-85 or so, then the phone uses standard charging to top the battery off. I have also not noticed any heat while charging using the OEM charger provided out of the box. Believe what you will. I just don't care how you charge your battery.
Sent from my XT1575 using Tapatalk
Why would the phone discharge faster after a quick charge? Isn't one hundred percent one hundred percent? I'm not flaming, I'm actually curious if there's a difference.
Idk who came up with this, your battery does not drain faster when its charged faster, its not logical.. All turbo charge or any type of quick charge does is supplies more a more faster charging rate based on the volts and amps it puts out. This should not effect your batteries life in anyway.
I can understand the thinking behind this but there is absolutely no way you can test this correctly because you aren't doing the EXACT same usage every day. Something will always differ.
Was this ever an issue with previous Moto X's?
After about a week's use I feel like the battery has a break in period. I was getting horrible battery at first. The past few days have been par (4ish hours SOT). I've only used the OEM Turbo chargers once but I have several other Turbo chargers (mainly from Galaxy's, Turbo's, etc). Almost every charger in my house could be considered a "Turbo charger" but I only receive the notification that the device recognizes a turbo charge on the OEM charger.
That said, I have worse battery life if I charge all night. It's as if the battery fully charges, then depletes, but still registers as 100%. So shortly taking it off the charger, the battery will quickly drop to low 90's and soon into the 80's. If I charge to 100% and unplug soon after my battery life is as expected.

You are making an interesting point here. Anyone else can confirm?
I'm going to do a test myself. Before that I want to add that I've noticed when charging with turbocharger(I've used only the OEM's) the charged capacity tends to go a little over the 3000mha, it becomes something like ~3300mha and after plugging out it still stays like that until 90% where it stats under 3000mha charged.
I charge every night with slow charge. I am at 95% after 1 hour and 45 minutes unplugged. Checked some news a few texts and 2 phone calls. Seems normal to me.

Battery drain is pretty evident. I am on MM Indian ROM and below are the findings.
1. Used turbo charger to top it up at 100%. Dis-connected the charger. WIFI is enabled and network is 2G (data off). All background app sync is disabled, and the only major applications running in background are firefox and whatsapp.
With medium brightness and browsing, the battery will drop to 97-98% within 5-8 minutes.
2. 100% turbo-charged at night. WIFI enabled/2G network (Data off). Woke up in the morning after 6 hours and battery is good at 98%
WIFI off and network moved to 4G/data and after browsing for 10 minutes, the battery falls to 85%
3. Instead of turbo charger, used Xaiomi MI pad charger (non-turbo) and my experience with #1 and #2 are pretty much the same.

charging - amperage/current quickly drops to ~440mA regardless of battery %

in the last week my battery no longer "quick charges". i have 'Ampere' installed so i'm used too seeing it charge at around 2800mA. i vaguely understand that phones charge quicker up to around 80% and then at a slower rate for the remaining - it's not this.
when I plug in the, current starts at ~1300mA and climbs to just under 3000mA... and drops to ~440mA in a minute or so.
it doesn't appear to be the cable and/or charging block that came with the phone - using a 1A charger from my last phone gets similar results and i purchased a new cable that's compatible with high speed charging.
i really wanted to love this phone.
I have a Samsung quick Charger from a Note5, and it has never quick charged my PureXL (actually super slow charges it,) but after the last update, I noticed I got an overvoltage error using it....
The reason is that this phone is not quick charge enabled. That's actually something that needs to be built into the SoC + Kernel support. You have a solid 2A charger, it'll go fast, but it can't rapid draw like say, the premium motos or a OnePlus.

sorry, i don't think i explained myself that well. i'm pretty sure that i've noticed a change in performance. when the phone was new i remember the current being high when battery % was lower, and then decreasing as it charged.
in the last week or so it seems to be charging at a slower rate and with the original 2A charger and cable. if the battery is at 20% the current will increase quickly to something above 2800mA and then immediately decrease so that by the time it's at say 22% charged the current is at a steady 440mA.
oh! ****. i didn't realize that 'quick charge' was actually 'Quick Charge™ by Qualcomm®'.. nice and generic sounding.
my pure xl was doing a full charge in less than 3 hours. as of last week all of a sudden it takes 10 hours to fully charge. using original charger and cable. can anyone shed a light on fixing this problem?

My Nexus 6p is now facing the same problem as yours. It charges less than 3 hours before and all of a sudden two days ago, it has taken 10 hours to fully charge. With all cables and charges faults ruled out, my only guess is the fault lies in the phone. I don't think it is the USB port either. I believe it may be something to do with the software I cannot comprehend. But I currently don't have the time to reflash my ROM. This Resurrection remix ROM served well for the past year.
Currently, my amperage averages out to 350 mA. Sad. I wish someone with knowledge about this can reply to this thread. It seems this question has been lingering here for more than two years already. Are we the only ones who face this problem?

Charging speed

To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the OnePlus 6T can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!
dash charge (now called fast charge) is crazy fast!!
Still, I would only recommend using that feature if there is a real benefit - i.e. time is of the essence. The battery will age quicker being dash charged all the time.
saw 60 percent at 35 minutes and 38 seconds, which is more or less in line with what OnePlus claims
Incredibly fast compared to my old Honor 8. One example I have is the first charge I did 5 days ago when I had bought it at a pop-up event here in Sweden. I had used it for about 1-2 hours with the screen on when I was setting it up and trying out the phone. Then when I plugged it in, it went from 36% to 75% in just 24 minutes. That's insanely fast
I've also noticed that just like OnePlus claims, the phone basically charges at the same speed with the screen on as if I would have had the screen off.

Can you provide any factual basis for this statement? Research or articles from established professionals in the field of battery charging?
Everything I've read from reliable sources state that the biggest impact on battery longevity is temperature. Repeated heating (or extreme cooling for that matter) will accelerate the "aging" process, as you put it. OnePlus has actually solved this problem by offloading the energy conversion that causes heat to the power brick, leaving the phone cool during charging (pretty ingenious). I've also read that not always charging the battery fully to 100% can prolong longevity, which is why you get charging strategies on laptops that will stop charging at 80% or 60% if you leave your laptop plugged in 24/7.
Point being, the ONLY way to slowly charge this device would be to use a third party charger and/or cable.
The reason I ask this, is that the manufacturer, OnePlus, clearly states in their documentation that comes with the phone or dash chargers to ONLY use the charger and cable that came with the phone.
Please charge the OnePlus Dash device only with the official Dash Power Adapter and Dash Type-C Cable. Using unauthorized adapter can be dangerous and may void your warranty.

I'm not completely opposed to the idea that this could just be a marketing ploy to get you to buy their own adapter and accessories, but again just want to know if there's any substantial proof that fast charging, by itself, degrades the battery faster, of if it's just a case of incorrect tribal knowledge.
Thanks.
You are correct that the rate of charge and discharge alone are not the only deciding factors on lipo life and certainly not the most decisive ones.
Excessive heat, especially on high charge levels, is the biggest factor for increased aging.
As you mentioned extreme charging levels (completely empty or full) will also contribute to faster aging, albeit the impact is not that extreme for these low current-draw Lipos used in our phones (as opposed to high-drain Lipos for instance).
Discharge and Charge at high rates will also contribute to the speed of aging, but not as much as heat.
When a lipo spends most of its time one medium charging levels at moderate temperatures and is only charged and discharged with low rates on it will have the longest service life.
This is common for all Lipos, just how much a low or high rate is for that particular battery differs (low drain, high capacity VS high drain, low capacity cell)
With Lipos everything is a compromise. Max and min voltages, max temperatures, max draw are values the manufacturer has chosen as the best compromise to reach the intended MTBF. All these numbers are not physical absolute barriers.

First of all, how many device support Super VOOC? How many device you can buy outside China with VOOC?
Super VOOC is 50W, the same like Huaweis SuperCharge 2.
Did you test SuperCharge 2 or VOOC?
My OP6T charges up to 100% in 1hr 22mins, so I don't charge overnight anymore. Go to sleep on 40% and charge in the morning
The combo of battery life and crazy fast charging is for the first time breaking me of the "plug it in overnight" habit that I have had since my first cell phone over a decade ago. I can keep my charger at my desk, plug it in for half an hour, and be at 100% with almost no chance of running out before the next morning. That means fewer vampire chargers around the house wasting power, and fewer charge cycles lost leaving the phone plugged in long after it's full. I wish I had swapped to OnePlus sooner - I think I have finally found a phone maker to call my favorite.
The charging Speed with "Dash charge" is amazing.
Within few minutes the battery is from 0% to over 50%!
Generelly I can only say: Amazing battery life. The best I ever had with a phone (except Nokia 3310).
I started to charge when the battery was 5%. It took around 1 hour 20 mins. I can say this to be quite faster when compared to the devices I have used previously, that too when the size of the battery is much bigger than the previous phones.

The incredibly fast charging, coupled with the insane battery life (especially in dark mode) has made me totally OK with no wireless charging. I used to leave my phone on the charging pad at my desk most of the day, and on my nightstand charging pad overnight. I never had to worry about charging at all and plugged in maybe 20 times max over the last two years with my Note5. I said I'd never buy a phone without wireless charging, but the $350 or so I got for my Note5 exchange for this phone was just too tempting to overlook, particularly if it set up my family for the next two to three years (our current phones didn't have band 71 and Samsung said no more security updates). The only thing I was really worried about was wireless charging and whether or not the battery life and dash charging would be enough for me to overcome range anxiety.
It has.
So I'm thinking of keeping my dash charger at home ,and my 30w aukey charger at work ,I take it this will be ok to use ?

It should be. If you are starting from full in the morning I doubt you will even need the charger are work except for very rare instances. I have gotten 7 hours SOT that was mostly gaming on this thing, moderate use you can easily get 24 hours, light use around 48.

Question So what is the best android charging habit...?

So I bought POCO X3 Pro earlier this month...So I play games on it mainly and the question is which kind of charging habit is better?
1.Frequently charging to make the percentage between 50%-100%
2.Charge it to 80-90 and try not make to make it fall below 20% and charge only once in a day?
The second option is a bit far fetched for me...Though I will try
My habit is 1 + 2: when around 50%, charge it up to around 90%.
Of course I'm not paranoid about it. But I do check battery levels most times I pick up my phone, to decide what to do.
If you root your device, you can use Battery Charge Limit.
You can set the maximum charging percentage, like setting it to 80%, then the charger will stop charging.
For our POCO X3 PRO, we need to go into this app setting and change "Set Control File" to the one with mi6 or something I don't clearly remember.
ArrowOS has this smart charging built-in.
I personally use my old charger to charge it slowly.
From what I observe, the Xiaomi 33W charger will rise the battery temperature to 40°C, which is bad to the battery. My slow charger will increase to ~33°C.
The fast charge is for convenience and emergency eg. forgot to charge at night and need to rush in the morning.
Frequently charging between 40~80% is better for battery health in long term.
Advanced Charging Controller (acc) is a good module to do this under control. It also has links about battery health explanation. (Battery university)
It is best to keep it between 20-80 present and not gaming while charging. I use my old slow charger when i am not in a hurry.
i keep mine at 70% max. i charge when it gets to 40%. I use arrowOS so i can set max charging and it resets the battery stats as well, so i know which apps eats power next time
Trying to keep it between 40-80%, with 10min break before recharging to cool down
Actually, I always keep my battery between 25% and 75%, then I restart the device once a week. Finally, I will use it until 0% one or two times a month before charging fully to 100% , I have read in a newspaper, it is necessary for digital devices.

If you want your phone battery health to last longer for years, like 2 years or more, then it's better. Info is here: https://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
For long term, battery will degrade and loose it's capacity, so your battery die eventually, then replace, then die, then replace...

If you are wealthy enough to change your phone so frequently that you don't even want to concern the long term damage to phones, then forget about it and go for the TOP. (And coffee for me )

To be honest, I wouldn't worry too much about any loss of capacity in the battery. My oldest still active device is now 5 years old and even with that I do not notice any significant loss of capacity. Typically all of my devices charge from around 5% to 100%. My Nokia 7 Plus was charged almost daily by me for 2 years and by my brother for a year before that, but I don't know how he charged it. Still, I haven't noticed any change in the running time to this day.
Maybe it's not the place to ask, but I was wondering, is there any way to know if a Xiaomi charger is fake? I want to buy a charger between 10-18w to replace my 33w charger in order to reduce my POCO X3 PRO battery's suffering, but I live in a third world country where is VERY difficult to adquire imported products and I don't want to buy a fake one from the local online marketplaces, if you guys could please help me I would appreciate it

Just buy any 2 Ampere, 5 Volt charger. It should be fast enough, but not too fast. It doesn't have to be a Xiaomi charger.

If you have a laptop, use it's USB. It most likely will charge VERY slow, to the point that you want it to charge faster.
Edit: The alternative way is to use Magisk module Advanced Charging Controller (acc)
You need to unlock bootloader, install Magisk, and install Advanced Charging Controller (acc) module.
Then you can restrict the charging current or voltage. I tried with the official charger and it can be charged below 500 mAh, so below 2.5 watts.

If you have a laptop, use it's USB. It most likely will charge VERY slow, to the point that you want it to charge faster.

All interesting posts. I wonder however:
What about having the device connected to the charger most of the time (at work place) with 100% most of the time, so it is de-charged only a small time of the day? So only at times when really moving around some workdays or in the weekend the device gets down to 20% or below.
I have now changed the 33W (12V/3A) Fast-Charger with the older 18W (9V/2A) Charger of the RN7 I have.
Would setting the charge limit to 80% give a huge benefit if I would like to use the device at least for 2-3 years?

Connecting to the power all the time at around 100% is bad. It is at the limit of Over charging, the battery may bloat up and destroy the screen.
If you want, it's better to set it limit 40~80% and connect. The importance is the battery temperature. Don't make it hot. You can check it with Ampere.
The benefit is about the battery. You might not need to replace it often when you encounter like cases of sudden drop of percentage or sudden shutdown.
Huge or not is subjective.

Regarding battery temperature at least after reaching 100% I never noticed a hot or even warm phone.
I taught the device/system has some "charging intelligence" when always connected, so that the phone is directly using the power from the cable while the battery is not drained?
In Stock MIUI (debloated) or xiaomi.eu without root it is not possible to set a different Battery Charge Limit then?

When it's about to reach 80% or 90%, smart batteries now will charge slower automatically, so you don't feel the temperature.
However, when you see it in ultra-fast charge, like 40% charing to 70% in 30 minutes, the battery rise to 40°C or higher (as I observed.) Can even go higher depend on climate and using while charging.

This can be done with Advanced Charging Controller (acc).
I had answered similar questions here:

This control needs root.
Unless it's built into the Rom.
ArrowOS version 2021-05-07 had Smart charging that can set a limit threshold without root.
But developer said will remove this funtcion. See in his Rom thread for his reply.

Question Steady charging not working

I'm on the latest .151 build and I think steady charging does not work for me.
Maybe I didn't get the functionality or I misunderstood something but it doesn't matter what charging mode I use, it always charges incredible fast unless I use my old charger.
When I plug my device and go to the steady/ultra steady settings it claims it would take as long as a 18 watt charger and would take ~1h until it's full. However it mostly only takes around 35 minutes (I don't go from 0% to 100%). When I use my old (Oneplus 5 or Nexus 5) charger it takes around 1.5h.
Is there a way to tell if I load the phone via hypercharge or steady charge? Forum mods mentioned both share the same animation and no matter if you use hyper or steady it's always listed as hyper charge in the lock screen.
As soon as I plug my device all notifications appear claiming it would be ultra steady and scheduled.
So my questions
- how can I tell if it's working?
- does it work for you?
- would be using my old charger a better alternative?
- how long takes ultra steady for you?
Things I've already tried
- I did a factory reset
- cleared all caches of Powermaster app
- restarted the phone multiple times
I am on .151 as well, and use the steady charging feature without issue. I typically plug it in around 30% give or take a little bit, and let it charge to 80% with the limiter. Usually takes 25-30 mins to complete this. I was skeptical at first as to whether or not it was working as intended, but I have a USB gauge which verified it was indeed working. I will run it again the next time I charge to give you the exact information, but as I recall it was approximately 16.9w at about 2 amps.
Thank you very much for your answer. So you use steady - not ultra steady?
Because my experience is nearly the same I plug it at ~25/30% until 80% and ~55% in ~30 minutes seems pretty damn fast for a 6000mAh battery.
Especially when I look at the settings when I charge my phone it shows ultra steady === 18w charger but when I really use my old 18w charger it takes waaaaaay longer. That's why I was so confused.
I would be really really glad if you could help me understand if it works as it should or not. I expected a charging time of 1.5h or so to be honest

I do use the ultra steady charging option. I popped it on for a minute to get the read out. I am going to kill the phone sometime this weekend and measure capacity with the device and see what it says.
Ignore the other readings on there for now as I didn't reset them before taking that pic.
I see, thank you very much.
So it indeed charges (compared to other/older phones) extremely fast even on ultra steady - at least in my opinion.
Why are you going to kill the phone O.O?
You don't like it?

I meant I'm going to let the battery die completely then use the USB tester to confirm battery capacity.
I really like the phone and plan on keeping it barring any issues
So I let the phone die and did a full charge from 0%-100%. I did it with the phone turned on. It appears to be charging at the claimed 18w the whole time. Next time I do it I will do it with the phone off. The mah didn't get captured properly for sure though.
For the first 3% it did charge at a speedy rate, which I did include a screen shot of. Once I turned the phone on that rate was never seen again.
