I've never actually timed the charge speed of this phone, but I thought it was fast. Until I actually timed it. It charged from 3% to 100% in 50 minutes... That's insanely fast. Anyone else has this ''problem''? hahaha. Post your charge times!:good:

If you're getting slow charge times, you're probably using a crappy cable. The G2 seems to throttle down to 1.2A regardless of the source if the cable is not really high quality. How it determines this I don't know, perhaps the voltage sags.
no it goes down to 500ma if the data pins in are not chortend.
I use a modifyed 1$ cable and get 1.82a
it's not about quality it's about how the pinns are connected.
to make it 100 u have to have a 800ohm resistor but it works with 0ohm (chortcircut)
I use the cable that came with it. Shooting pins seems like asking for something to go horribly wrong.

there's something wrong with your battery stats. it takes about 2+ hours from 5% to 100% with the included cable.
From 10 to 100 : 1h 40min exactly....

Check working usb thread, you will see.
1% to 100% ~1:45. Charging time varies per AWG, heat, voltage drop, top/bottom conditioning.

No, we're talking about using a sane charger, which has the data pins in their correct configuration.
Lots and lots of posts about various charge rates on various cables, although typically resolves to around 1.2A for lower quality cables, only better cables will pull the full 1.7-1.8A.
From 0 to 100% while the phone is off takes about 1h 50m, using phone cable charger.

well it wasn't the first time I've had this 'issue'. I too thought it was battery stats error but it've drained and charged it fully a few times and it's still like that.
1:50 to 2 hours if i use the phone while it's charging ! i've experienced 1:30 although
2x battery claims that it charges approximately 24% each half an hour.

Battery drains out from 10% to 1% and (OFF) in a minute, yes one minute...
Any one has the same problem?, is this normal?.
I noticed it does not happen every time, what could possibly cause the problem?.
Thanks
Hello,
You should try recalibrate your battery. To do that :
- Discharge your phone and let it turns off itself
- Power it on and wait that it switches off
- Charge your phone when it's off during 8 hours
Good luck !
and after you fully load your battery go into recovery and wipe the battery stats and charge it up again

I've seen a similar behaviour on many other Android devices. IMHO you can consider 10% Battery as almost Zero - you just shouldn't let it run that low.
I have noticed one thing,when phone is charched with charger battery life time is around 5 days.
When i charge phone over computer, two and half day is max of battery duration??
Anyone else noticed that?

Same thing for the car adapter. Weird phenomenon that cannot be explained from a scientific point of view, but it's my own experience.
Havn't noticed that with my neo, however I never have my phone below 20% for too long, have a charger in my travel bag, 1 in the car and 1 at home, always a cable to plug in nearby.

This is probably because USB port in PC is limited to 5 volts and that means that the charging will be slower and not so efficien.t probably same thing with car adapter.

PC usb = 500mA & 5V
Wall charger = 1A & 5V
Some PC motherboards had specially made some USBs ports for charging. There is output ~800mA. Read your pc manual.

I don't think so, but if you want to be sure, you may just turn it off while it is charging.

from 1% to 100% it is about 5hours
to 100% - 5 hrs...
I notice that my tab charges faster or slower depending on what the tablet is doing. If i am using it, it takes about 1 hr for every 10%, if its on but screen locked it is about 1 hr for every 20%, and if it is off (but plugged into outlet) i notice it is about 25%-30% for every hour. But it depends on your adapter, power fluctuations and etc (lower voltage gives less amps if the power is not consistent)
Around 5 hours on standby mode.. Never realised during off screen charged.. I heard XOOM one charge faster than Tab..

How long should our Note II take to recharge from 0% to 100%? Problem with practically all Android phones is that it just takes way too long to recharge. Last night I plugged my Note at about 1AM, depleted all the way down. When I woke up at 7AM, it was still at 70%. Does that sound about right for everyone? I understand that we have a huge battery capacity but the limitation with the microUSB port is definitely there.
no something is not right...my device recharges in 2.5hrs from below 10% to 100%
You using an outlet or CPU?
if CPU, are you directly connecting to a USB port or a hub?
My cpu charges so slowly compared to an outlet.

You tried different outlets?
I would turn the phone off, try dif outlet, try charging it, see if it is any better.
If no, probably something hardware related.
if yes, probably something you have installed then i would just restart from stock.
It takes me about 2-3 hours with the oem charger.

I've been having this problem too, and I can't really pin it down. I'm using the charger that comes with the S3,which is only rated at 1amp so I know that's the biggest factor. However, sometimes it charges to full in a few hours, other times after a night on the charger it will have only made it to 60% or so. The real stumper is that it only tends to drain about 1-2% an hour in deep sleep, so it's not like it's draining faster than the charger can keep up. It seems completely random. I'm ordering a 2amp charger to see if it helps, im sure it will, but I'm just confused by the random nature of this.
Yea something is definitely wrong. Mine charges in about 2.5 hours from near 0%. Try a different outlet

Yeah about 2-3 hours is my usual charge time from 20% to 0% range respectively.
I still can't help but feel that that is somehow slow though. Can't tell, it's been so long since I had a small battery I don't know what a fast charge is nowadays.
Going from zero is way different than going from 1% the battery tries to protect itself so it trickle charges for a while. Honestly going from 10-100 should not take more than three hours probably closer to two

not sure if this helps, but do you have light manager installed?

The Note 2 for me now charges faster than any device I have ever had.

Hi,
This is what I have found. Sometimes when the microusb end is plugged into the phone that the phone charges at usb rate instead of ac which is wall outlet. I only have this problem with a standard usb cable in the car. Will change it soon but. What you can do after you plug in the microusb into the phone goto settings then battery and see how the phone sees the charging its getting. It will say either usb or ac. Ac is full charge rate usb is much slower since usb like off a pc or laptop has a lower output to your phone.
If you see it takes more than 3 hours to charge your phone and it says ac in settings then you definitely have a problem with either the charger, usb cable or phone.
Thanks,
Bryan
If you're using the cable and charger that came with the phone, you have a problem. Based on what you reported, I'd say you're using a 1A or less charger.

The app can only tell how much different the battery is, not how much juice is actually flowing into it. Meaning, the possibility exists that you phone is *using* juice while it's charging, lowering the amount of difference the app can see.

Thread fail. Voltage output, as verified with a Fluke 77 Type IV multimeter, is spot on 5 VDC. Current, which is governed by the phone, has been verified by many to a max of 1900 mA.
I can see just from the screenshots that the app is detailing misinformation. Were your phone actually charging at the rate indicated, it would take approximately 26 days for it to fully charge, assuming no use, from the 76% in the screenshots.
Oftentimes you get what you pay for. Such is the case with Amazon's Free App of the Day sometimes.

Help a newbie out.
I had an iPhone 5 that charged ridiculously fast compared to older phones.
When I'm charging my new S 4, how do I get the faster charge rate?
I'm currently using the Moto 2 USB wall outlet charger that came with my razr maxx hd. And it seems like it takes way longer then my five and I chalked it up to having twice the battery.
Is there a faster way to charge?

The new charger is amazingly fast, if thats a word. I was going to use my.old charger from the s3 at work but its so slow it barely keeps up with use and can't keep up if I'm running my wifi or playing games. Now I just need to find a car charger thats as fast as the new charger.
Sent from my SCH-I545 using xda app-developers app
Keep in mind there's more to it then just the wall charger's output ability. There's something in the S4 that recognizes the original sammy charger and turns up the charge rate yet will only allow a trickle charge on other non-sammy 2.1A wall chargers.
It appears that dome people are aware of this and have managed to modify the non-sammy chargers to enable the faster charge. Then there's some semantic confusion between "quick charge" and "fast charge" features that may be enabled in roms or kernels.
All I know is I wish there were more info on this stuff.
A little knowledge of how Li-ion batteries charge is an important thing. Li-ion batteries have special charging requirements.
The part you plug into the wall... thats not a charger... its a power supply. It provides a 5v DC output at up to 2 amps.
The charger is built into the phone, and it determines how to use that available power to charge and power the device.
Li-ion batteries charge in a two stage cycle that is called "constant current/constant voltage". It is also important to know that a battery's voltage drops as it is discharged. (this voltage drop is how the battery meter gets its information, as it is predictable when tested under constant loads... the variable load of a phone is why the meter seems to be inaccurate at times)
During the first phase, "constant current", the battery is fed a constant current at the same voltage as the battery is currently outputting. As the battery takes in energy, the voltage rises but the current is kept constant.
The second phase, "constant voltage" starts when the battery reaches its highest voltage. (or more accurately, its highest safe voltage, which is around 90% capacity) During this second phase, the battery is fed a constant voltage, (the max voltage) and the current varies. The battery will draw as much current as it is able, and this rate slows naturally as the battery reaches full capacity. When the current drops lower than a certain set amount, the charger stops the charging process and the battery is said to be fully charged. This second phase is slow compared to the first phase, and that is why it can seem like the last 10% of charge takes longer than any prior 10%.
Some phones use the power supply to both power the device and charge the battery, the battery is electrically isolated during charging... but most charge the battery without isolation. Either way, the power from the power supply is being used to both charge and power the device, and this limits the charging speed.
This also limits the maximum capacity the battery can be charged to while in the device, because the voltage/current measuring is less precise. Unfortunately for these phones, the charging is controlled by software, and not simple hardware circuits that are isolated from the battery power. In fact, even when charging the phone with the power off... the phone is still actually powered up but in a low power background mode. This mode is actually a special screen off recovery mode. CWM recovery has had several instances of bugs, where the phone could not charge if the battery died to the point of powering of the device. Because the phone could never power into the special mode to start charging, due to this special mode being missing from, or bugged in CWM.
Also... these batteries have on average a 2-3 year lifespan, and also limited number of recharge cycles. The 2-3 year life is the same even if the battery is unused. As the battery ages, it looses capacity.
Charging at slower rates is better for battery lifespan than higher rates. Now the batteries in the S4 and especially the Note 2 are larger, and 2A is still considered a fairly slow rate, but of course 1A is even better. If you tend to charge only at night while sleeping, it may be better to use a 1A charger.
Awesome explaination !!! That makes complete sense and explains things. The point made in a prior post, about the phone recognizing the new charger, thus charging faster makes sense as well. The new charger must "turn on " the quicker charging on the S3 as well, because it charges my old S3 as fast as my S4. I didn't try the charger on the older firmware but it definetly works with the latest update.

Hello guys, I bought this phone recently and I don't know if I'm having an issue or not.
The phone charges unusually fast either with the fast charger that came in the box or a normal one I have laying around. Even when fast charging neither the phone nor the charger get hot (the charger just a bit warm but that's it). I use a USB c cable I bought a while ago, not the one that came with the device, but it's supposedly a good quality one.
The thing is that the battery is understandingly discharging pretty fast. What could be the issue here? The cable? Battery calibration?

Way shorter than it's estimate. With a fast charger, from 50% to full in about 30 minutes, and that getting a bit warm. Not even the charger gets hot. With a normal charger it doesn't take much longer. Those are the things that seem suspicious to me.
