Ok, so I have an AT&T SIII running AOKP (was on CM 10, waiting for a bit better 10.1 stability in the Bluetooth department). I just found out how awesome the PS3's Dualshock 3 controller is for gaming on android. I'm considering purchasing a GameKlip for it.
-Anyway-
I know that the SIII's charging rate is capped somewhere between 750-1000 mA. I did some searching here on XDA, and it seems that buying a 2A charger wont charge the phone any faster because the charge rate is capped by the phone. I get that. My problem is that my phone will discharge 10% or more per hour on AC power (OC'd, brightness up, PS3 controller) while I'm gaming. I also understand that concept.
My question is: If I use a 2A charger, will the potential excess power prevent the phone from discharging while gaming, or will it be irrelevant? I assume the former.
While everyone is on the same topic, what is the highest charging rate that OEM's typically allow? Does say, HTC or Motorola tend to have higher rates? I'm not against switching to another phone (or carrier if I have to) if it means no discharging while gaming. The way it sits, if my battery is already low from using it during the day, and I come home from work to play some games, the battery will just die even though it's plugged in. Seems counter-intuitive to me. Other than this issue, I have my battery usage down to a SCIENCE, and I usually have idle drain less than 1%/hour while on WiFi with MINIMAL wakelocks. I think because of that, this drainage thing really drives me nuts!
What do you guys think?
Thanks!

Honestly, I've been using a 2A Charger since i purchased my phone three months ago. Im using the one from the nexus 7, but to answer your question.
I've noticed no difference in discharging using the 1A vs the 2A, the only factor that can that is your kernel and rom.
Since i've switch to a ktoonz kernel my battery life is improved by 75%. (using custom settings)
Also can i suggest possibly looking at a extended battery pack? I have both the gorilla gadgets and the hyperion. Both are amazing i was able to get 3 days on it, under heavy gaming 1.5 days.
Im using only a 3150maH battery right now, as i stopped gaming on my phone, bought a sick computer.
Funnily enough, I also use a DualShock 3 with my device on occasion, normally while on AC power. I've never noticed any power dips, but that may be because I'm not particularly pushing the device to its limits in the process.
Anyway, I think the meat of the matter is this: does the phone limit the amount of current entering via the micro-USB port (which is then split between battery charging and normal device usage), or does it limit the amount of current going into the battery? If it's the latter (which I'd consider more likely, given that the micro-USB port is expected to handle at least 1.8A), then you'll notice a benefit from using a more powerful charger under the circumstances. I don't actually know if that's the case, though.
Does your kernel support quick-charge? I don't know the science behind it, but it allows me to charge my phone from dead to 100% in less than half the time it normally takes.

Yes it does, but I thought fast charging only makes USB charging the same rate as AC charging (plus I heard it can permanently damage the USB interface)... Therefore my understanding is that the hardware charge cap still applies.
we all know that one of the benefits of A70 is it's so called "Super Fast Charging"
well...as super fast as the claim, its super fast in dissapointing as well
TTHE PHONE IS CAPPED AT 15 WATTS ONLY !!!!!
as soon as u charge the phone it jups to 32 watts, so, its not the outlet that have the issue which is decent, then u wait a couple of seconds annnnnnnd....its stuck at below 1000ma with 14.4 watts of power
i dont get it, why the heck it doesnt stick to the 25 watts promise ? am i doing something wrong ?
i am using franko kernel app to measure the watts
From what I gather it will only 'fast charge' when the phone is in standby. I.e. The screen is off and phone not being used ....
But I agree it is a poor fast charge.
My honor note 10 which is a 22w super charge on a 5000mah battery charges way faster even with the screen on and phone being used.
Maybe it's Samsung just being cautious with there batteries.... [emoji848]

With screen off, 0-100 in 1 hr 40 minutes. If the screen is on it'll charge normally. This is to prevent overheating and damage to the battery

well my friend, i doubt it, cause i have rooted my A70 and used ACC (advanced charging control) to completely disable the cooldown thingy to fast charge, well, nothing helped, stuck at 14.4 watts for eternity
i mean...assuming your theory IS true, i tried leaving my phone screen off for 15 minutes, then opened it and checked the wattage from the notification...aaaaaand its still 14.4 watts, i mean, if what you say is true i should probably find it at like 25watts and it drops down 2 sec after i open the screen, but it NEVER reaches this 25 watts thingy, and the ampere app is stuck at 1200 max mAh
I think trying to work this out while running a custom kernel is a fool's errand. We have no idea how charging work with custom kernels yet, so you dont know if it's a kernel problem or a hardware problem. Since you dont seem to have tested this prior to switching the kernel, you have no baseline to compare it to other than what other people who are running official firmware are telling you..So not much help then.
I'll say this though, I checked mine with a power meter and not a software readout: 25w screen off, 10ish screen on. That's below 80% charge, anyway, at which point the consumption drops.
I think my A70 charges pretty fast and I'm okay with how fast it is, no matter the watts.

i am already running the stock kernel, its just i patched it using magisk and that's it, so i believe there is no issue from my side as i am using the stock kernel
Mine is charging pretty fast, no issues on my part.
I have a POCO F3 and I know that it's normal for the phones to get a bit hotter while they are charging. I noticed that my phone while charging can get a temperature of 40º celcius, then the temperature comes down gradually I believe. When it's not charging, it's usually between 20-25º celcius. Is this normal?
Phone are supposed to heat up while charging (especially Fast Charging "33W"). Normal human body temperature is around 37c. So your phone is pretty safe on 40c while charging. But it isn't if it is on 40c all the time.

It's only when it's charging. I've noticed that the temperature decreases when it's approaching 100%. When it's not charging it's usually between 22-28º celsius

This phone uses fast charging till 90% and after it slows down. That is the cause of temperature decrease when it's approaching to 100%.
I used a slower charger and only a fast charger in emergencies, heat and electronics don't play nice.

The faster the charger, the higher temps, therefore more battery degradation.
However, 40°C is still o.k. I think. I think the advantages of using Fast Charging are bigger than the disadvantages.
Keep in mind, the biggest battery degredation comes simply from age.

Never use your phone with heavy tasks / call / gaming ... while charging : not only the heat will damage your battery, but this can explode, especially in hot environment !

The disavantages are bigger than advantages :
. heat degrades battery faster
. explosion risk still exist and is higher with fast chargers
. heat not only damages the battery but thermal paste in the motherboard and the storage ... you will notice lag / data corruption after 6 months no matter what you do/update the software !!!
I use only old chargers 5v/2a max ... even if my devices are modern and support fast charging !
Fast charging is a marketing trick to force consumers buying new phones in a short period while your phone can last more than 4 years !
Bad software/kernel optimization is the main culprit for fast battery draining.
Age/ Time : NO ... my Redmi Note 4 (mido) still holds (after 4 years) its full battery capacity and i can reach easily 9 to 10 hours SOT. (i use self compiled lineageos)

I think you are a bit overprotective. Explosion Risk? Come on. I know it can still happen, but it's so rare.
Yes generally heat causes Battery degradation, but it also depends on the phone and how good of a job the manufacturer has done.
10 Watt Charging is really slow man...
I also don't think it's simply Marketing, because Batteries have also gotten bigger. We went from 3300 mAh batteries, to 4500 mAh batteries in many phones nowadays.
Chipsets are also getting more and more efficient through 5, 7 nanometer-technology, however the increased clock-speed (and other stuff) outdoes that mentioned efficiency-improvement.
I really understand your concern, but don't you think it's overprotective? 10 Watt is really slow in my opinion

Don't forget the heat generated by the modern cpu/gpu ... so yeah add this to the heat generated by the battery itself !!!
... and don't forget that smartphones are closed environments for the electronic components (some manufacturers add fans for heat dissipation and they know why they are doing this) !
I don't care about slow charging since ... i remove the sim card and put it on another phone while charging.

So should I buy a slower charger? Or can I keep this one?
gringo80 , I agree with the things you have mentioned. I have only one doubt, does the use of slow chargers with the new Mi 11x will support it completely and doesn't have any side effects?
In Layman's language, slow charges can be used with today's generation Android phones?
9to5Google has released an interesting article. I never noticed this, since I charge my phone slowly overnight with a 5 watt wireless charger. Have you guys also experienced this? Can people here with root can confirm wattage measurements? Especially the decrease overtime?
As it seems, both the Pixel 6 & Pixel 6 Pro are affected by this.
Google is notorious for having algorithms that sometime suck and need refinement, just like Adaptive Charging that only likes you when you are a normal human being that wakes up in the morning; if you are a night worker, Google doesn't care about you.
Pixel 6 doesn't actually charge at 30W as Google implies, analysis finds 22W max
A new analysis of the Pixel 6 charging speeds finds that the phone never hits its advertised 30W charging speeds, even under ideal conditions.

At this point I'd rather have a broken adaptive charging setting as the culprit. Maybe it's active without people having the toggle on. As far as I know, the "trigger" for adaptive charging is an alarm set in the morning. Would be interesting to know if the people with slow charging problems have any alarms set at all, to rule that out.
I was going to take the charger back because I had to pay for it and for the most part was no faster than my previous pixel phones, a couple of days ago tried the two chargers side by side, and this time the charger was apparently going to be 30mins faster to fully charge, nothing scientific rather looking at time till full on lock screen.
And as you mention in the evenings charges super slowly, so no point having a charger that I had to pay for.
The has been plenty of people saying that their phone never fully charges, and my guess also is no alarm set
I'm having similar issues with wireless charging so I think this is probably part of a bigger problem with the phone, and probably why they haven't put out the new pixel stand yet. It could really tank the launch if they released it today and the phone still has all these problems and can't charge at the advertised 23 Watts.
After reading this I'll be sending my charger back, no immediate need for it at the moment, perhaps further down the line if Google sort it out on the phone.
Google need to address this because a lot of us have bought the official charger and it's not giving what is advertised. They'll keep quiet about it though until any sort of noise from it dies down.

Mine was charging at 27.4W (fluctuating between 25W-27.4W, I'm assuming because I had the display on) using Google's 30W power brick. My battery was at 71%, I'm going to try it when the battery is lower to see if I can get 30W.
The article says it doesn't go over 22W, that's already false in my case.

Not sure how you're getting 27.4w there? 30w is approximately 6000mah current draw, no?

It depends on the voltage. The specifications of the power brick say that at 5V and 9V it outputs 3A of current.
You can see from the screenshot I posted that the phone was pulling 3.076A @27.4W.
P=VI, so V=P/I
V=27.4W/3.076A=8.91V
It seems pretty spot on to me.
Attached the specifications of the power brick.
After 2 days of trial and error, it's thermal throttling due to battery temp.
It hits 96.20f on the battery and goes from 2.8mah at 15w to 8-900mah at 6w
Full charge speed comes back as soon as it's under 94f
This is something I never dealt with with my OnePlus phones....
6000mah always, no issues 40 minutes to full..
With my testing, I've found that,
While charging
Power saving mode with CPU throttle, screen rate throttle, Bluetooth off doesn't help keep it from throttling...
Charging, I can play a YouTube video slid to the side off the screen and browse the internet and after a good 10 minutes or so it's bouncing in and out of fast charging
Playing a game while charging get me around 400mah charging lol
Takes 10 minutes for a single percent when gaming when it gets up in temps
I'm a business owner and a heavy user when I'm using it.
I atleast now understand how it works and what the limits are.
Brightness is half way and on auto.
I would be fine with it getting a bit warmer to keep the fast charging going for sure...
Now I set it in front of the AC if I need some quick charging lol
Slight edit.. it even throttles charging when closed and not being used...
You telling me this phone I paid almost 2 grand for throttles like a baby after a little light use? I noticed today that Enhanced processing has been removed and the option to change the screens resolution has also been removed. I swear my note 20 ultra still kicks this phones butt
It's give or take, it doesn't like charging,
I was playing genshin impact when it got warm and dead lol, but when charging it's straddling the throttle on and off if your using it for sure, download battery charging monitor pro and watch for yourself
She games well I love it, I'm sure I'll be able to manage it, but just coming from a one plus it's mehh
Samsung has limited the charging speed while its in use since their old models blasted some time ago left and right. That is the reason samsung no longer gives faster charging speeds like other brands. We are stuck with 25w charging plus slow charging while using the mobile
It only hits full speed when the screen is off

Incorrect, I can take a screen recording. If the batter stays below 96f it won't throttle.
Like I said my fix is to put the phone in front of my ac for a minute flat for like 15 minutes of play while charging at full speed.
It has nothing to do with the screen being awake.. it's all on the battery temp.
I tested it by putting my phone in front of the AC when warmed up and as soon as it drops below 94 it's back to full speed.
Yes it's Samsung, but they will learn someday when other phone companies start pushing into the US like OnePlus has

pushing a battery thats charging full power is asking for a fire to happen. This is EXACTLY why Samsung and other manufacturers put these safety measures into play. Users think they know better when they don't and create safety hazards. Like dude please learn basics about batteries before you start a fire.

For starters, I came from a one plus with 2x the charging speeds. What makes them so special to have it down?
And on top of that, I deal with lithium polymer batteries on a daily basis. Owning rc cars I've handled 100s of those "house burning down" batteries.
The phone doesn't even get warm.
I'm sorry your just used to following Samsung and what they say is the fastest standard for something lol
They gotta lack somewhere
I understood those limitations are for battery life. But you can be unhappy about it.
That's understandable and personally I don't care if the charging speed is not blazingly fast.
I remember my Note 7 well.
