Fast charging always on - Samsung Galaxy S7 Questions and Answers

Hi all.
My S7 mounts the second PHN oreo update, G930FXXU2ERG2.
From this update the phone only charge in fast mode, in fact I noticed that even deactivating the fast charge from the settings, checking the charging amperage with an app it's very high, and as expected recharge time it gives me about 1h20m, instead before it was about 3h.
Has anyone else noticed this problem?

[Q] Z3 Bizarre slow charging via magnetic connector?

Hey guys first time posting here.
I've had my Z3 for almost 3 months now and have recently noticed some strange things going on with its charging.
Ive been using a third party magnetic charging cable for entire time I've had my phone and they work really well, they charge at a good speed. However, recently the charging time has slowed down dramatically. For example, last night my phone was at 31%, i charged it for 5 and a half hours and it only reached 36%. I checked the battery info tab and it says AC, also the graph showing the battery level shows that the charging is very slow, it says it was charging for the full 5 and 1/2 hours.
-also, no apps were running and the main power user was the screen (as always) which was off.
I don't know what's wrong, I did a battery partition reset a week ago since i was having problems where the phone won't charge past 80% and the reset fixed the 80% problem, but now this is happening.
The charging cable i use is not broken since it works in different power outlets throughout my house and charges the phone normally.
I don't use ROMs and it has the stock factory operating system.
Anyone else have this problem?

Rapid battery drain from usb_notify and dwc3-otg? Also no "charging" dialog...

Rapid battery drain from usb_notify and dwc3-otg? Also no "charging" dialog...
Hi guys, I seem to have a weird problem and haven't been able to fix it at all. My battery over the past few days has been draining pretty rapidly when not in use (6-7% per hour). I checked BetterBatteryStats and it shows that usb_notify and dwc3-otg are keeping the phone awake at all times - it literally does not go into deep sleep.
I have no idea how to fix this! Nobody online seems to have issues with these wakelocks. When plugging in my phone to charge, I also don't get a "Fast Charging" or "Cable Charging" notification for some reason. I have to restart the phone to see the updated correct battery percentage - otherwise it just stays stuck at the same number it was when plugged in to charge.
No idea what's going on here, anyone have any suggestions? I've tried reflashing roms, flashing a different rom, and plain factory resetting.
I have a Samsung Note 5 on t-mobile and I am experiencing a very similar issue. My phone has the same two wakelocks, similar battery drain of 6-9% per hour while not using. The only peculiar thing about my situation is that I still get my charger to charge my phone but it does not fast charge and the cable charge has been taking a grueling 5 hours to fully charge the battery. Another thing, although not consistently, the phone will prompt me with usb options as if the phone is plugged into a computer. When I first got the phone it was fast charging the thing from 10% to full in a little over an hour. We're you ever able to figure this out?

Fast charging using normal adapter?

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.

Question Fast charge only after reboot?

SO i;d been neglecting to check fast charging because my charger is european and i'm in Canada. Eventually, i got a oneplus 65W charged and tested to see it in action, alas, no fast charging. After doing the rounds of swapping cables and even trying the original charger with a converter and still not successfully fast charging, i recalled having installed accubattery and it flagging 80% charge. On a whim, i uninstalled it and then tried charging again ; lo and behold, fast charging no problem!.
fast forward a day or two, i check to see if the phone still fast charges and nope, blue orb city . I figured if it wasnt a fluke before tehn maybe its a software thing so restarted the phone, plugged it in and bam, orange orb of fast charging goodness.
it;s been a few days and ive had teh chance to se ethis in action consistently (charge, blue orb, reboot phone and orange orb).
Anyone experienced something like this and know what could be causing it ?
I'm on RMX3370_11_A.06 (2022.01.19)
My next steps will be the painful uninstalling apps one by one to see what the culprit may be assuming it is an app
Fast charging speed only for sometime . then it going back to normal charging speed. Accubattery show s that. Charging rate around 3500ma. Not 6500ma
I think Realme is doing this for the health of the battery... It's the same behaviour on other devices from BBK, Xiaomi and so on...

Our phone has two cell battery and they both are are charged simultaneously to increase charging speed, Accubattery can only measure one of the cell, That is the reason it shows Estimated capacity of 2500mAh wheras in reality we have 5000maH (2500+2500)
Also for fast charging,
1) Environment should not be too hot.
2) Close background Apps.
3) Put phone on Airplane Mode.
4) Dont use phone while charging.
Thanks, bro. Okkkk that's why my estimated battery capacity shows ~2480 something like that. My mobile took almost 50 minutes for 0-100 % . Even though I'm very happy with that speed. Is anyone planning to install the beta version of 13ui? Please don't. Many apps not working properly. Camscanner is the worst one affected. I tried almost every latest version of camscanner . but no luck. . Battery life and performance seems fine.
