[Q] Maximum Charging Rate, Gaming, and other Nerdy Stuff....

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.

Phone Drains faster than Charge

Hi XDA Forum!
I've got a Sony Xperia Z5 Premium that drains faster (or at the same rate) than it charges playing games such as Pokémon GO but also oddly using applications such as Snapchat. Obviously this is inconvenient as I'd like to be able to charge my phone via a portable charger and use it at the same time but the phones battery percentage either stays the same or goes down slowly while plugged in (whether its a wall charger or not). When checking the charging current with AIDA64 and Ampere, I get jumping readings but it usually stays around a charge rate of 300mA with the occasional jump up. Any reason for this ? Currently using build 32.2.A.0. 224 (Android 6.0.1 Marshmallow).

Realised that the Jump from 17% to 18% took way too long and looked at the readings for the charging current. Please see attached while I'm still sane Help on this is really needed!
Edit 1: Bear in mind the charger I'm using for this is rated for 1500mA and when using USB ports rated for 2400mA, the same issues occurs and with different cables (definitely seems like a phone issue rather than equipment used-issue)
Edit 2: Also bear in mind that my brightness is on lowest, WiFi is turned off, GPS is on Battery Saving and all other apps are closed via the recent apps drawer.
Send help pls!

Another Imagine depicting how bad this issue actually is. I can't use my phone at all while it is charging or else it just doesn't charge at all. The image shows that from ~10:00AM until now (4:00PM) it has gone up by roughly 4%.

Stop being so impatient, we all have lives here... Next, stop using your fone while it is charging and let us know how that goes. Next use a different wall outlet and charger and cable and see whether things improve. There are quite a number of factors at play here. Lastly, factory reset if all else fails...

When charging without using the phone, it charges slowly but surely. It is when the device is in use that it drains faster than it is able to charge (which is inconvenient seeing as I need to use it while Charging for a Pokemon GO event). I have tried multiple cables and multiple outlets and have just performed a factory reset yesterday (via Sony's Xperia Companion) which I'm not so sure has fixed the issue as I'm still getting the low current readings. If the issue persists I'll just get a Samsung Galaxy S7 next month since I'm pretty sure they wouldn't have this issue and I'll most likely have to send my current Sony Xperia Z5 Premium to Sony for repairs.

One more thing, the Sony Xperia Z5 Premium's battery is rated at 3.8V and 3430mAh but looking in AIDA64 the voltage shows as 4.106V. Normally as a somewhat tech savvy person, I would be extremely worried quite a bit if voltages were this off. Any help?

Battery-gate has everyone paranoid.

This sounds like BS. When Samsung investigated 90+ cases of exploding batteries, it found that 26 reported cases were fraudulent scams - this was in the news today.
It sounds like the same ****.

This.
I would believe the below from the article before I'd believe Samsung's stupid enough to make the same or similar mistake twice. I was worried about QC on the replacements considering how fast they're racing down the production line. Mine's perfect BTW. Any articles about Samsung because of what's happened is guaranteed click-bait. A Note 2 overheating on a plane made front page news with whatever (still to be determined) happened to it being tied back to the Note7 issue.
"The issues being reported in South Korea are related to minor errors with the mass production of the new units."​

Mine seems too also but I thought it was all in my head. It seems smoother and snappier for want of better words. My old phone would occasionally get choppy and stutter as if it was struggling with something in the background. The new one doesn't. It's on AT&T and the new phone's shipping s/w was the same as the old phone's updated s/w. Curious.

My s7 edge and note 7 (both exploding and non-exploding versions) have always had times where they charge slower than they discharge. (Waze + Pandora when it is super sunny, so 100% brightness. Even on QC2.0.)
The new note7 (and/or new firmware) pops up a warning to say as much. The S7E had an overheat warning that came up occasionally in similar conditions (even air-conditioned, DC summer is warm..)
I think the only difference is the notification that its happening, which is nicer than discovering after a drive that you have been losing power the whole time.

I'm experiencing the very slow charging issue. In fact when I was watching a movie while fast charging it was losing charge!?

I have experimented the same thing, actually ending with less batt while using and charging with other devices, so, this happening with the note 7 indicates nothing wrong with the batt

Customers in South Korea who received a replacement device have reportedly complained the phone's battery is overheating and drains too quickly after use, according to a report by YTN, a TV network in the country.

Fast charging does not seem to want to work on my new one, with stock charger brick and cable. I am hoping I don't have to go BACK to TMo and get another new phone.

my replacement seems identical to my original, same charge speed, same discharge speed.
as for the people saying about watching movies and such and the battery ending up lower, that is normal, if you are running the screen and charging not only does the battery get warm, so does the CPU so the phone will start to throttle the charging. I've had phones in the past that refused to charge once the CPU got above a certain temperature. this is just people being paranoid or looking for a way to get money as mentioned above with the fake tales of exploding batteries.

Odd. I use my Note7 (pre and post replacement) with Android Auto via USB. Android Auto really puts a load on the phone. Even off the wimpy output from my car's USB port the phone never loses charge and frequently gains it. My previous Note5 was the opposite. It would stay even most of the time but would lose charge on occasion. The only difference between the two scenarios is I got a Orange-E 12" Type C USB cable to use with my Note7. So my experience is different than yours.

I suspect the screen is the big drain. 100% brightness is vicious. Isn't the screen off for android auto?
Things it's usually doing when it drains (starting from 70% or so) :
Overheating (direct sun, no ac pointed at dash or top/doors off)
BT music streaming + wear
GPS
100% brightness
QC2 (aukey car charger)
Even without overheating that combo usually only gains me about 5% over 30 minutes.
Unrelated, but without getting too far off topic is AA worth the jump? (~900USD if I want my steering wheel controls and stuff)

Yep. When in use and the display is on its black with the Android Auto logo. But the phone's still using all its radios and if navigating pushing data to an 8" display so the phone's definitely under load. I have a Samsung Fast Charge car adapter but the problem with Android Auto is it doesn't let you connect by BT so the car's USB power output is all you get. But as a comparison under the exact same conditions the Note7 definitely either drains less or gets more power than my previous Note5 and both phones are/were configured identically.

A black screen with amoled means the only pixels lighting up are the ones in use. The screen itself is a massive drain so the more pixels are lit up, the more the juice is drained from the battery. That's why AOD doesn't kill the battery fast.

Ive used a USB multimeter on both my old and new note7.
No matter what, old or new note7, the charging rate gets cut exactly in half when charging with the screen on. This happens when using a quickcharger or a normal 2.4a 5v charger.
So if you want full speed charging the screen needs to be OFF.

On my replacement Note 7 I noticed that if you are doing allot with the phone, it still gets hot, the battery does take a little longer to charge with both the Samsung charger that came with the phone and an Anker IQ 2.0 / 3.0 charger. The phone does seem a little snappier/faster though.
I just want a removable battery to end all this bull * and I will pick the battery I want to power my phone.

The biggest advantage for the integrated battery is that the unit is completely sealed from water.

I beg to differ, because they have that wireless backpac battery that is completely sealed from water for the Note 7. The purpose of the permanently installed battery is for the NSA to track people since the battery cannot be removed from the phone.

Charging speed

Hey guys,
I have recently purchased xiaomi mi 6 and this is my first quick charge phone so something got me worried. My battery charging speed seems to be too fast for me. Although I don't think temperatures are worrying however I'm conserned regarding long term effects.
I have xiaomi mi 6 6gb ram 128gb storage ceramic edition model.
These are pictures taken from battery app from playstore and image of my charger.
If anyone have some advise about this it would be great.
My greatest consern is that charging speed doesn't seem to diminish as charge is getting to 90% after it hits 90% it slows down dramatically. But from what I know it should change charging speed between 60 and 70 percent to little slower then from 0 to 60.
Is this damaging battery?
Screenshots below.
Thank you.

Totally fine. Its QC 3.0. Imagine this: QC4+ charges ~50-60% in under 15 minutes.

Oh such a releaf. Thank for replying.
Anyone got idea if this has any at all negative effect to battery?

No, higher battery voltage - slower charge, you would damage your battery in few weeks without this slow down.
Also avoid heavy load of phone when charging

Would they put a fast charger in the box if the phone couldn't handle it? Nah probably not. Maybe Apple would......
Should you worry if you use the stock charger or a certified QC 3.0 charger? Definitely not its fine.
Are you still worried?: use a non QC 3.0 charger like 1.5 amp.
I use my old Sony one and it works equally well.
I find a slower charger gives slightly longer SOT.
The fast charger is just useful if I need power quickly.

Thanks guys

Question Thermal throttling

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.
