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.
How to smart charge the Galaxy Note 2 battery
The way you charge your device is very important and it can affect your battery life a lot. Charging it wrong will make it drain quickly and the battery will also last less, requiring a replacement after 1-2 years of use.
To smart charge the Galaxy Note 2, you have to only plug it in when the battery is below the 10% level and never unplug it until it is 100% charged.
You should also know that when your battery reaches 10%, it will last longer than usual. To understand better, it will drain much slower from 10% to 0% than from 20% to 10%. So don’t panic if your battery level is low, because it can hold for a very long time, especially in standby mode.
Never use low quality chargers, because they can damage your battery hand even the device. Only use original Galaxy Note 2 chargers and try not to use the USB cable for charging your device. Always charge it in the wall socket, because the USB port power fluctuates and can damage the battery. Also it will charge much slower.
Battery maintenance
Usually the battery is the first smartphone component that dies, having a lower lifecycle. Though you can prevent this by taking care of it.
The best way to prevent it from getting damaged is to avoid pulling it from its socket. The battery has some golden pins that can scratch or get dusty, so if you pull it out and back in multiple times you can damage the pins.
In order to help the battery work the way it should, always make sure to clean the pins with a soft cloth whenever you pull it out. This way you will keep dust away from them.
When buying a new Galaxy Note 2 battery, make sure to get an original one, as other might have a lower battery life and can have a shorter lifecycle.
Increase Galaxy Note battery life by disabling features
The Samsung Galaxy Note 2 N7100 comes with tons as features, like we just said at the beginning. But nearly all of them are big battery eaters and you need to be careful when activating them.
The CPU and display drain a lot of battery, so make sure to setup the display to turn off faster. Also don’t keep it turned on when you don’t need it.
3G and 4G are the biggest battery drainers on a smartphone. You should only keep the 3G or 4G network activated when you use the internet actively. If you really need a permanent internet connection, then go for 2G, though this eats your battery too. The best way is to only connect to the internet when you need it.
Do not keep the WiFi,Bluetooth and GPS activated when you don’t use them. They can drain your battery very fast even in idle mode, so make sure to disable them when you don’t need them anymore.
Live wallpapers are also big battery drainers. They consume a lot of CPU and RAM resources and also use your display more intensively. So you should never choose a live wallpaper. The most battery-friendly wallpaper is a dark one, which doesn’t use any CPU resources and also doesn’t requires the display to be very bright.
You also have to take care what apps you install and always look at Settings > battery to see who drains the most battery. There are some apps than run continuously and prevent your device from getting into “Deep Sleep.” This is the standby mode that helps the device conserve very much energy. If an app prevents it from getting into this mode, you will notice a very low battery life.
Please let us know if you found other ways to increase the Galaxy Note 2 battery life. We are also curious for how long did you manage to get your device running between charges.
wow thanks mate quite a good one!
Thanks!
Also you should add that if you always need to be connected to internet then its better to keep connected through WiFi as it consumes less energy than using EDGE or 3G.

Thanks it's useful
What?
No.
1. Deep charge cycles on a lithium battery accelerate the failure of the battery.
2. The device can determine the type of source it's plugged into, computer usb ports are safe.
3. Non branded chargers are safe if they are quality made. You just need to stick with quality and 2 amp/ short cables for decent charge times.
Sorry man, but those 3 things you listed are some pretty big misinformation that can easily be verified.
There's nothing "smart" about doing a deep discharge if your trying to preserve a 10 dollar battery.
After installing the new rom..I charge my battery full..then remove battery stats then drain full to zero for cycle.after complete ..I use smart charge method..that is .when my cell battery below to 10 something like 9 or 8 then I connect charger .and really it helps me alot

Deep charge cycles are for avoid "memory effect" and It apply to old Ni-Cd / Ni-MH batteries. Don't apply for modern Li-Ion battery. There is much more chance that the deep drain affect negatively the battery of a GN2.
Li-Ion battery keep better performance if never going less than 50%. But the difference will be barely noticeable.
Personally, after several tests on my own, I don't bother anymore with that (I mean for the modern Li-Ion type). Sometime you have a great battery, sometime a crappy one from a bad batch. I have seen battery died fast after "by the book" charges cycles. And others seem to last forever, no matter how bad I maintained her (like my 2006's laptop).
Anyway, thanks for sharing, even if you are wrong on this one
I don't know if you're wrong or right because when you search the net about battery charging, you find everything and it's opposite. But I disagree on three points:
- The battery is beefy and you really have to work hard to make it last less than a day
- I bought this incredible phone because of it's features. If I have to cut half of them to avoid drain, why did I buy it?
- I dare say that most of the people who buy a Note 2 somewhere are a bit "Tech-Nuts". If you're not, I am, so I don't mind if my battery doesn't last two years because I'm not sure that I will still have this phone all that long.
And if I do and the battery is dead, I'll buy a new, genuine, Sammy one to continue.
What's it worth to live 100 years if you can't have a drink from time to time, maybe have a smoke or whatever? Plug your phone in or out and use your GNote 2 happy
Lol everything has its cost turn off everything to save battery what is fun in that I have a smartphone to use it and be happy with animations and display and games otherwise get a 3310 it is best

is there any way to charge ze551ml fast till 100%??? it only charge fast till 70% then very slow charging. Any kernel changes or any tweak that can make it possible, please tell me.
That way you get Galaxy Bomb 7.
If it fast charged up to 100% it would significantly shorten your battery's life.
You can't. This is intentionally made to prevent your battery from overcharged.
It's not the kernel problem, it's the hardware

You CAN, but you need to build your kernel yourself as you need to modify the battery driver.
As this is not recommended (like AT ALL), you won't be seeing someone offering such a kernel

There's no way for ZE551ML in terms of software, well incase there is, you'll just end up torturing your phone's battery as if it only supports 60℅ for 40mins, notice that your phone gets hotter and getting warmer over time after it hits the threshold, it is required to prevent your phone's battery from taking too much heat for a long period of time.
Perhaps just buy a new phone like Galaxy S7, LG G5, etc. that supports Quick Charge 3.0 atleast they have upgraded its components in terms of hardware to support faster charging.

Batteries need a balanced charge for longevity.
You could fast charge from zero to 100% but expect to kill a battery once a month.
Smart phones hey lmao
That's no necessary, just decrease a little time.
Buy the ZenPower.
Maybe adding a temperature check while charging could make it possible without explosions
I'd rather not cook my phone. Thank you very much. Lol

So I am curious how people are using their battery mods? I have a Tumi that came with my phone (swappa). I am grateful to have it though I realize it may be unneeded with the Z play. I was surprise the first time I used it to notice the phone does not sleep with the battery mod on. Is this normal? It correctly kept it at 80% for most of the day but I believe it probably wasted quite a bit of energy doing it.
Another thing I was surprised at was how HOT the MZP got when I charged it with the turbo charger. It was fast! I am curious at what cost this speed comes at. I am tempted to leave the battery mod on and charge wirelessly over night. This would be a much slower charge and possibly better for the phone's battery. I have had bad luck with batteries going bad and I would like to care for this one the best way possible. Would this be be better than just running a turbo charge for an hour each morning before leaving the house? I expect the phone will last the day without the battery mod without problems.
Anyway... I am curious to hear how others are managing their battery and using the battery mods in you have one. I am sure I can learn a thing or two. Also, any research on if turbo-charging decreases the life of the battery? I know they are designed for it, but they are also designed to last a little over a year. Moto won't be upset if I have to buy a new phone in two years. Thanks for the conversation!
Despite of what the research articles on Internet says, I have stopped plugging in my devices overnight on regular basis after I have had my share of bad luck with swollen batteries. I don't have a battery mod for my z play but I try to care for my battery as much as possible. Since phone gets charged in less than 2 hours with turbo charger, I generally charge it in day time or before going to bed. If I am at home and I am not in a hurry, I use a normal charger to charge my phone. It's well known that heat the known enemy of batteries and whenever I plug in turbo charger, my phone gets hot. Highest is 42 degrees only though ( ambient environments plays a role). As summers are approaching here, I simply switch on the fan whenever I charge using turbo charger.
Though turbo chargers are designed to charge fast acconpnained by the compatible chipset, I highly doubt that companies had some real progress in lithium batteries and they are not meant to be tinkled like that so I am a bit sckeptical regarding long term battery health when constantly used with turbo chargers.

I am curious as to how is everyone's battery life been? I pulled my phone off the charger at 7:05 am and currently sitting at 73% at 9:06am.

Is it me or is there no setting to automatically turn on battery saver mode when the device gets down to a certain percentage?? [emoji848]

Strangely....the battery drained faster than it charged for me. Of course, that's an exaggeration, but Quick Charge on this phone isn't as fast as other phones.
I can say that using it while charging DEFINITELY affected the charging speed more than my last phone. It does not charge quickly while charging AT ALL.

Using your phone while it's charging does not destroy your battery. It may not charge as fast because you're obviously draining it at the same time, but it's perfectly fine to use the phone.

charging and discharging at the same time causes heat, which does destroy the battery, unless you have a unit with something like oneplus dash charging that heats up at the wall instead of at the battery

It's a MYTH. Do a simple Google Search. And if it did destroy the battery, we'd definitely be hearing of a battery shortage simply from everyone driving around using their phones for GPS while plugged in.

hmmm my search turned up mixed results. some people think it'll make your battery explode, and that has been debunked. it is still debated (from what i can see) if doing heavy tasks (like gaming) while charging will degrade battery.

Your battery simply starts to degrade once you start draining and recharging. There's a difference between degrade and destroy. If it really destroyed our batteries, phone companies and cell phone carriers would be telling everyone to absolutely 100% do not use your phone while charging. That's just silly. How many times do you walk through an airport and see people sitting on the ground by an outlet, so they can charge and use their phone? Same with laptops. The batteries in cell phones now are so much better than they were before.

That's an old "wise tale". I do it on every phone whether it is needed or not though. I actually do it twice. I take it to around 10% and back up to 100. I still fully charge it before I even use it. May be a waste, but for some reason, it gives me a certain "pleasure".

Hmmmm. We discuss 2 separate things here.
May you still use your phone when charging
Of course you may
Will it be charging as fast when its on and being used in contrast to being blocked?
Of course it will be charging very much slower
Those people in airports may either have very much cooler CPUs in their phones like MTKs, Snaps 660 or Apple A9s. They don't produce as much heat as SD820 or SD845 so shey can still keep battery cool and let it get charging., or they put their phones aside and let them get battery charged fast because its not charging as fast when being used. Like G7.
Using G7, especially gaming or watching Youtube on mobile cell produce too much heat and battery gets warm fast. So to prevent Note 7 style overheating and explosions both Samsung and LG makes speed of charging lowest in that case. Even that was stated by Samsung's advertisements when Galaxy S8 was introduced. You may search for them on Youtube. LG does the same, it become charging with 0.5A like form USB 2.0 port, lowest possible speed. It prevents battery from heating to avoid degrading and explosion. Turn screen off, put phone aside for half an hour and let it suck up juice
