My GS3 takes about 3-4 hours to charge from 0% to 100%. I am on stock and am using the OEM wall charger that came with the phone. Is this normal?
Mine takes around an hour or two I believe it used to take around the same as yours but it doesn't last as long. But how long does yours last

Mine take over 2 hours from 5% to 100% using stock wall charger,,, 3 to 4 seen like a lot.
The answer is... it depends.
If you're charging with the phone on, it will take longer, if you're charging via a usb port, it will take longer.
If the phone is off and you're using the stock wall charger, you're charging at a maximum of one amp. If you have a stock 2100mah battery (2.1 amp-hours) and your charger is 100% efficient (never happens), the best possible 0-100% charge time is... 2.1 hours, it really is that simple
Now, you're not getting 100% efficiency, plus the way lithium batteries charge, at around ~50% capacity, the charge current steps down gradually from 1 amp to nearly 0 amps, so your real full charge time with phone off is probably going to be closer to 4 hours than 2. The step down is necessary to avoid over-charging. The logic (usually in the battery itself for phone batteries) to determine full charge is when the battery reaches 4.2 unloaded volts. Charging current will increase the voltage reading, so as it gets closer to full, charge current is gradually stepped down to maintain the 4.2 volt full charge state. As the current approaches zero and volts stay at 4.2, the charge controller knows that the battery is full.

I always drain completly my battery then I charge it for 8-10 hours even if it is showing 100%

3 hours is the average using the included 1amp A/C charger.
Charges 10% about every 15 minutes for 0% to 90%, and charges the last 10% in about half an hour.
(don't bother trying to charge using your computer's 0.5amp usb port, though; takes forever, especially if you're using it while charging)
There are reports that the charger that came with the s3 is garbage.
I was using the s2 cable to charge and it took approximately 1.5 hours.
Now it's taking 3 - 4 hours.

The charger that comes with the S3 is NOT garbage. I tested charging times against a "better" 2.1amp charger about a month ago and there was no difference. (If your custom kernel supports "fast charge", then there'll be a difference, but your battery will suffer. Better to stick with 1amp)

That doesn't make any sense. I think you're just not remembering correctly. Test again and report back.

Flashed JB today. Phone currently charging. Started charging at 2%, now at 41% and it's been 45 min. Estimate completion time, 1 hour 45 min.
So the culprit is not the USB charger, but rather something I had installed on ICS. I suspect it is the launcher I was using, which was GO launcher. Prior to JB, i was using apex and it was charging a little bit faster than GO, but still wasn't acceptable. I think it was 3ish hours for full charge.
My current JB setup is pure stock launcher and apps.
With stock charger it takes my phone approximately 2.5 hours to go from 5% to 100%.

I can confirm that,my AT&T S3 has been charging with that charger for 6 hours and I am still showing a 50%,so I had to grab a Motorola charger and it went up from 50% to 73% in half an hour.
Freaking Samsung,there's always something.
I'm on Slimbean 4.2.1 RC1 w/ lean kernel and my phone will usually last (with average daily use) about 3 days on one charge. The rom/kernel supports fast charge so I can get it from 0-100% charge in under an hour and a half. On stock rooted rom I was getting maybe a day and a half of battery life. Darned AT&T bloat lol

So how do we decide the most efficient charging method possible? How do we look at the Amperage of the battery and the amperage of the charger and decide what's best?
Also what's faster? Wall charging or fast/quick charging to a USB line?

Fast Charge will make it charge the same speed the wall charger would (but breaks storage mount while it's turned on).

:good: I started charging my s3 at 8:30AM this morning. and at 5:50PM it's showing 96% charged. taking 9 HOURS! to ALMOST CHARGE?? I ALREADY REPLACED THE BATTERY ONE TIME WITH ANOTHER ONE. BOUGHT THE PHONE NEW FROM METRO.
SO MAYBE YOU ARE RIGHT THE CHARGER IS GARBAGE. I WILL TRY ANOTHER WALL CHARGER AND SEE IF IT WILL CHARGE FASTER.
THANKS! FOR THIS POST!

This doesn't mean you battery is "on charge" for all the time... once the battery is 100%, the charge changes to something called "trickle charge". At this point charge does not happen continuous, but like a trickle to maintain the 100%.
Pull the phone out at the end of 8 hours of charge, and notice how quickly it goes to 99. Pull it like 10 mins after it says full, and it takes longer to go to 99%.

Higher amps charge battery faster... but... at the cost of capacity... At approximate 10% more charge than the battery is optimized of, it kills the battery by as much as 30% sooner. So its not really worth that. At the same time lowering the amps by 10% increases life by about 20-30%.

1 hour is like kinda too low... non stock charger?
My s2 takes approximately 3.5 hours to charge. Why? Btw, is it bad for the battery if after the battery is fully charged, it's still plugged for approx 6 hours almost every day?

I'm using original charger and I'm forced to shut down when ever I plug in charger. I tried other usbs and same thing happens, I can't use it while charging?
Also I charged it overy night to 100% turned it on about 30 mind later and it was at 92%....what's going on?
Thanks guys!
Mine does the same this tablet takes a lot to charge you can't use it when charging or it will shut down

That's lame also I had it on for 3 hours and playing castle clash and I'm already at 35% do games drain that much battery? When I had nexus 7 2013 it lasted for ever....:crying:
Yes, @one hour of the room two about 25% battery drain, blame the screen so nice but so hungry

I think I'll exchange it if it's still doing the same thing I'll just get the nexus 7 again or the pro:--( but I like how thin this is
Edit:
I exchanged it, it seems to charge fine now while using it. It was a defective battery.
I got a Keedox quick charger 2.0 (with the logo on it) 2 days ago, well it's very deceiving as it will not always charge the phone fast, only one time over 3 I saw it really fast (65% in 30 minutes) but the rest of the time it's as slow as the normal stock HTC charger.
From the Ampere app it detected 1850mah speed till 80% then it drops to 950mah and above 90% 256mah!!!
Ok I bought it for just 13$ but how qualcomm approved to give them the logo if they are too slow?
Could it be my Rom the culprit? Viper 2.3
I remember back with my S6 it was blazing fast with the samsung charger
I'm using this Qualcomm fast charger 2.0 and it's fast works great every time.

That's how the 2.0 works. I'm using Aukey's 20. charger. The lower your phone, the faster it charges and as it approaches full charge, it drops the current down. A neat way to look at it is to take your phone below 10% then use the 2.0 charger up to 95%, then look at the battery usage chart, you would see the different charging rates on that chart.
HI, I have a ZUK Z2 Plus and I was used to charging it overnight. I was using the ZUI 3.1 and there was no problem in charging, no heating nothing even after charging it overnight. I was using the stock ZUK charger. Last week I have changed the ROM and flashed AOSP Extended latest build and charged it overnight. In the morning the phone was heating abnormally. I disconnected the charger and used the phone whole day and when there was 5-10% battery left I connected the charger and that's where the trouble started. The charger connects and within seconds shows disconnected. The type c port is heating a lot after connecting the charger. I tried another 1A-5V charger although it doesn't shows disconnected but it does heat the connector. On searching the forums (https://zukfans.eu/community/threads/z2-plus-not-charging.1697/)I found that maybe the voltage regulator is burnt. Removing it can solve the problem (may be I have not tried). I want to know what is the cause of this. Is it because of kernel? Or anything else? Please help
The problem is charge overnight, I had to remove the voltage regulator, now is charging.

I know it happened may be because of overnight charging but as I have already mentioned I was used to charging my phone this way in ZUI and there were no signs of heating.

Is Redmi 6 pro supports any fast charging standards (2 or 3) ?
Because it have SNapDragon 625 and it supports Qualcomm® Quick Charge™ 3.0
I don't know.
But I have charger from mate 9 and showing fast charging.

how much time takes to charge from 0 to 100% in fast charging. normal charge takes more than 2hrs to full charge.

Absolute no. Soc is supporting Qualcomm fast charge but Phone is Not. İs hardware limit. Not software. İf u buy qualcomm quick charge, its will not work, will charge like stock charger. 5 volt 2 amp is enaugh.

5volt 2 amp is already "Fast charge". Fastest way to charge massive 4000 mah battery. Use stock cable and brick
