Turn off quick charge

Is there a way to turn off the fast charging?

Just use a charger that doesn't provide quick charge.

ok, so if I use a htc one m7 charger, does it works?

Why would you want to turn off the feature?

To have more charge and discharge cycles, so as to have a battery that lasts for a longer time, in terms of age of the battery.

It would be nice an option to disable it, like in the SGS7. Especially for the people like me that charge the phone at night and doesn't need quick charge.

Why not just use a charger without quickcharge, e. g. 2A output or even 1A if you prefer? Very simple solution!

This is what I'm doing now. I'm using my girlfriend charger, but my car charger is QC, and I don't always want to use it and I'm not want to have two chargers in the car...

Okay, that makes sense! We better get an option to turn it off then.

I noticed the Axon charging current drops off somewhere above 90-95% capacity. Using the app Ampere and with the Axon's included QC3.0 charger, the phone will charge at a current of ~3A when the battery is below ~80-90%, and then when the charge capacity is above that, the charge current drops to around 0.3A for a slower charge up to full capacity. The charge current may even drop lower but I haven't observed Ampere like a hawk when charging.
I'm curious what's causing that smart charge current drop: the phone or the in box QC3.0 charger. If it's the phone, then using an older charger with a max output of 2-2.5A may be ideal for battery longevity. If the Axon battery is truly 3250mAh, then with a preferred C-rate of say 0.7C (I've seen recommended C-rates from 0.5C to 0.8C), we get 2275mA as the ideal constant charge current. If the phone also drops the charge current of this older charger when capacity is nearing full then it would certainly be better than using the QC3.0 charger.
However, if all of this fluctuating charge current is controlled by the QC3.0 charger itself, then it might be the better charger option versus one with a lower rated current output. The OP on this thread should test both out with Ampere and share the results.
Some good reading:

Quick charge rates are designed around the capability of the battery. I have extensive experience with system design around rechargeable cells of all major chemistries, and the large batteries currently used in phones can be charged at much higher rates simply because there is more surface area (more mAh) that in older phones. Quick Charge will never charge at a rate unsafe for your battery. Your battery is more likely to fail from simply age or damage due to a drop as opposed to quick charging.
The bigger the battery, the higher the acceptable charging current. At over 3000 mAh, the Axon 7 battery can safely be charged at a very high current.

Absolutely correct, like my previous post, but not an answer to the question asked. I agree that since the capacity is high at 3250mAh, a constant C-rate of 1.0C (up to 3250mA charge current) is safe. However the question is not about safety, but longevity of performance.
Lowering the charging C-rate to 0.5-0.8C could potentially mean the difference of good battery capacity performance for 1 year versus 1.5-2 years.
With Ampere I've observed the charge current on the Axon with QC3.0 charger as high as 3200mAh. At 1C, that's perfectly safe, but less than ideal for battery longevity. We're simply looking for an alternative at a lower C-rate of 0.5-0.8C.

So, is better a 5V- 1A than the original QC of axon?
I charge it in the night when i sleep, and I don't need a quick charge during the day.

Explained In short and ELI5.
If you charge ~300( charge cycles) times with the QC3 you will lose ~10% battery capacity.
10% off 3250mah is 325mah.
So roughly (depending on usage) after a year you will lose 325mah from your battery.
If you charge slow it is prolonged.

The MiA1 wasn't designed for fast charge so the battery will probably fail sooner.

This is not true at all. There's no special "quick charge battery" installed in phones that support quick charge. The SD625 supports QC 3.0 (it's listed right on the official qualcomm website), Xiaomi just decided to exclude the functionality in their kernel. That being said, I would make sure the phone is placed in an open area to make sure heat is dissipated well while quick charging. I would also only use quick charging on an as need basis. Putting it on a quick charger at the end of the day, every single day, just to sit at 100% most of the night is kinda pointless. A slower charger would be a better choice for over night charging if you're really concerned about battery health. These same tips would also apply to phones with QC support OOB.

Wrong. Fast charging is not just a function of the SOC but requires a different battery chemistry and improved charging algorithms built into the battery and charger itself. Heat is not the only problem with fast charging as you are alluding. Hammering the battery with a 'forced' fast charge is a good recipe for killing the battery prematurely.

Axon 7 Max battery in Axon 7?

Anyone done this? Replaced your Axon 7 battery with the 4100 mAh battery that's used in the Axon 7 Max? Same dimensions? Will it fit? Will it work?

that's way too much fam. I think the Max is a 6 incher, plus it's fairly different.
What may be possible is using an Axon 7S battery which is slightly bigger at about 3300 i thibk. supposedly they are the same dimensions

But is the max charge voltage the same?
Many Chinese OEM's will raise the charge maximum to have a higher capacity in specs but in reality that kills the battery and that extra bit of charge drains back off really quickly as it's overcharge. THL are a major offender in this. Personal experience with that one.

well it's going to be charged to 4.3 as that's the phone's max charging voltage in software, so in the worst case it's going to have the same capacity as the axon7 one. The battery doesn't define the charging curve

Is there actually any battery available with more juice then OEM one? I read in other threads some time ago that even those promising more capacity are just fake labeled OEM ones ... can anyone confirm that?

Does anyone have experience with it?

Check health of battery

Hey, my battery is gradually getting worse, how to exactly check battery stats? I AM using accu battery, And after a few battery cycles IT shows 4000/1500 mAh. How can i gry better readings? And if that's readings are correct, is IT better to buy new phone, or replace battery. Redmi 3S is enough for me, but maybe IT is time to move on?

If you are on a budget get the battery replaced or get a new phone

Did you try a full charge + reset of your battery stats ?

I replaced battery, long live Redmi 3s

Battery capacity lower than expected.

Hi all,
Using AccuBattery and it's telling me the battery is around 4160 mAh (that's from three charges so far). Obviously it should be around 4500 mAh.
Anybody else see this?
Thanks

I've installed the app to test your problem. It detected the correct battery capacity for me. The app tells you that you can adjust the battery capacity, probably because sometimes the reading is wrong.

No, no you misunderstand.
It detects 4510mAh which is correct. Once you've gone through a few charging cycles the app will tell you the actual capacity of your battery under the "Health" tab.

Me too, Accubattery says I have 4220 mA battery. Its around 5% less than original capacity (4510).
I see when battery is full charged, battery down from 100% to 99% quickly. On oneplus 7 pro I had the same problem, battery was "old" and OP7pro lost 5% quickly.
I don´t think it is enough to return the OP8pro, I will buy a new battery in the future when battery is older.

They use battery designed for max 4.4V. Advised capacity is correct if battery charged to designed maximum voltage however there is software limitation and you cannot charge battery over for example 4.275V in 7 pro. Real capacity is approximately 10% lower than advised. You have to understand that Oneplus is Chinese company so you cannot expect any reliable and trustworthy information from them.

4042mah on my one... But battery life has been great... It seems the voltage limit thing is the main reason.

4440mAh on mine.

Many reviews in playstore says similar problems on many phones.
Seems this app is not really accurate.

Thanks all

On new Pixel 4 XL I had 3850 mAh according to accubattery and 4100 mAh on LG V50. This measure is quite reliable after long time usage and you gonna see quite similar results like using usb meter. On my 7 pro I had 86% designed capacity and I have bought new battery - still 88% but when I noticed what's written on battery label all happened clear. Please never believe Chinese people even if it is global company they always lying because of they drink lay whit mother's milk and it's strongly correlated whit their totalitarian culture.

I just did 3 charges on my new op 8 pro and i'm getting 4419 mah ... :S

I did around 5 charges and mine is 4084mah, battery life is not great...

It's not accurate lol, don't trust it
