My galaxy s4 battery drains while charging.
My 4g data is turned on and wifi hotspot is also turned on. I also play Clash of clans while charging.
Should I replace my battery or my charger?

Download "Galaxy Charging Current" from the play store and check how many amps you're receiving. You should be getting more than 800ma for your phone to charge properly.

I'm receiving 600ma from my wall socket. Is the charger faulty?
Isn't this related to the battery swelling issue discovered recently ?

The battery isn't swelling. It lasts like 8 hours if no data use. So i think its not because of faulty batts.
Are you using the original S4 USB cable? you need a very good usb cable in order to change with high ma, it should be about 1500ma if you are using a good usb cable (with the original charger)

Depends on the firmware/kernel. Newer (stock) firmwares (>MGA) limit the charging at 1200mAh while the screen is on and 1900mAh with the screen off.
Custom kernels can charge at 1900mAh with the screen on.

Some cables are unable to generate more than 600ma. If it is the original Samsung charger, change the cable. If it is the original cable, get a 2A charger. If it's both, chances are, its the cable. Good luck.

First day i was testing different wall chargers (Samsung stock and non Samsung) with different cables combinations using a current widget. Results: original white Samsung data cable still in the box (bad impedance causing low current) and using stock wall charger with a generic data cable better than original.
We all assume hi is trying stock all charger and stock kernel...

The limit is the same (1900 with original wall charger and good data cable), the 700 mA difference is because screen consumption plus non idle cpu state... It is, 1900 always enter in the device, 1900 enter in the battery if no consumption (screen off), about 1200 enter in the battery if screen and cpu consumption (on).

You don't say, really? :good:
Older firmwares let the phone charge at 1900 with screen on or with screen off. More recent firmwares limit the charge to 1200 when the screen is on.
With a custom kernel this can be changed back to the original 1900, with the screen on. What is so hard to understand about that? No need to go into science again, I do understand all that irrelevant stuff anyway.

Thats amounts are not the limitation into the phone, but the net current into the battery, the difference between that limitation you refer and the actual current consumption for the screen and cpu.

Ok. Your tab will demand 1,5A only if it detects a original samsung charger (or if you are using a male-female usb adapter which simulates it); because this, the original samsung charger is 2A limited. Using a different charger, if you are using the stock kernel, it will demand only 450mA, just about the current that the tab drains swithed on with not too much activity so, the tab only will effective be charged swithed off and 3-4 times longnthan using original samsung charger.
If you use a modified kernel that allows it, you will be able to charge the tab at 1,5A even using a non-samsung charger, but be aware, the charger need to be at least 1,5A supported; if don't, two things could happen, if the charger is about new (or usb ports in a no-old pc), it will cut the current and the tab will permanently be charging and no charging (bad for the battery); if the charger is about old (maybe 10 years), surely it will not have a current limmiter, so the charger (or the old PC) will get smoked...
So, you will need to buy a 2A original samsung charger or, you can use a 2A non-samsung charger using a mod kernel as A1 kernel. Temporaly you can charge the tab using a 0,5A-1A non-samsung charger with the tab off, at very slow charging...

That is not correct.
With the stock kernel the tab will only (!) charge with the original charger, unless a special adaptor is used. When connecting a non original charger or connecting the tab to a computer USB port, the battery symbol is Xed-out and the tablet doesn't charge. With the adaptor, that fools the tab into thinking an original charger is used, the tab will draw up to 2 Amps.
With the modified kernels the tab will also charge with a non original charger or a USB port. In this case the current is limited to below 500mA to stay within the standard limits.

I've long time with mod kernel A1, I remember with stock kernel the symbol X you refer, but even I can not check it with current widget, I am almost 99% sure that really the tab is manteining the battery charge, what means about that 450mA, but maybe you are right and it is 0mA.
Both with connector (i've got one) and with the samsung charger, the current never will get 2A, because it is the maxime value form the charger, so because security standards the demand will be less than 2A. I checked it with current widget, it is 1,5A.
With mod kernels, it will depend of the modification and the kernel... I help AAccount to mod A1 kernel (which I am using) with this current issue, and we set it to allow charging at max current (1,5A), so the user should be care of the charger to be at least 1,5 or 2A max. If you plug it on a pc usb, three situations could happen: burn the power source if it has not a current limit system; automatically cut the supply to 0A; or automatically limit the current to 450 or 500mA if the pc power supply has this function.

Do you take that reading from the current widget logs, or do you read it off the screen when it's on? If you read it off the screen you're missing the 500mA of the running tablet.

Of course, from the logs and watching several values (helped by graph after measurements), with the screen off, and measuring both draining with charging connector and without charging. Measuring with screen off and no charging for some seconds you get the standby consumption (negative value, aprox. -450mA); the real charging current from charger is the diffeence between that measure and the measurement with screen off and charger connected (about +1050mA, so the difference, the charger current, is about 1500mA). I made several tests to check it. All this, of course, with A1 kernel.

Advantage: I can switch on the cable between sync and charge - all from a standard usb-port. And in addition, I have a 12V car-to-usb charger adapter. So I can charge also while driving around.
So is it me or does the s4 charge really really slow ?

Hi,
What is your charge time?
Mine is 2 to 2 and a half hours.
Which battery and/or charger are you using? After coming from the S2 I have noticed a large decrease in charging time with my S4, so this is very surprising to me.
Well I tried charging from my computers use port at work today only rise 20% in 2 hours

...*facepalm*. You're not using original charger and you're complain that the one you use doens't works so well? Do you know that original charger is pulling 2000mA out, while your usb-port is pulling between 300mA and 500mA (depends if it front or back usb-port and the quality of usb port). Do the math, 2600mAh battery and 300mA / h. Full charge should take: 2600:300 = more than 8.5 hours.
With original charger S4 recharges from 0 to 100 in 1h 49minutes. If you take a solar charger it will charge even slower (like 48 hours for 0-100%).
Next time try to use your brain before complaining.

Your Samsung power brick has the cable physically attached to it? If not, you can just use a longer cable with the Samsung power supply.
The included power supply is 2 Amps, whoever is getting long charging times, make sure you use either the original Samsung power supply, or comparable in amperage supply.
Mine charges in 2 and a half hours.
Mine takes 2 to 2.5 h to charge from 0 to 100 percent. You should only use the new white charger, it's more powerful than the black one from s3, it's output is 2.0A ,old one is only 1.0A. Newer use other chargers as they may mess up your battery or phone.

I have to check the amps but based on google the Nokia Charger is at 1.3 Amps. I need to remind myself to switch the short Samsung to longer Nokia cables.
Is it safe to get a higher Amp charger, the one that the iPad uses to charge my S4? No drawback execpt for a faster charging time right?

Take it this way, grilling meat takes for example 45minutes to cook completely. You take it to some powerful furnace like 2000degrees for 5minutes then what do you expect from it to give you back? Well cooked meat or some burned meat outside and maybe raw inside?

put it this way... the s3 comes with a 700ma charger. it charges a bit slow. and has a 2100mah battery.
the s4 comes with a 2 amp charger. thats 2000ma. it doesnt charge slowly if you use this charger. i personally am going to pop it on this charger when i get home from work and then keep it on my 700ma charger overnight... no reason to waste that powerful output, it will simply waste electricity.
make sure:
1. you use the charger that came with it
2. you use a cable thats as long as (or shorter than) the stock charging cable. longer usb cables tend to charge the phone slower.
also keep in mind usb ports charge any phone slowly. the s4 will charge even slower on them because the battery is oversized compared to most.
I'm using note 2 charger and if I surf Web while charging, literally it is not charging at all.. battery is not going up or down.. Note 2 was not like this.. i could charge battery even if I play 3d game..

It will do neither of those (Well, maybe the battery will charge a liiiittle bit faster). The charging circuit will pull only a certain amount of current, most likely around 1.2 amps, no matter how much power the charger can supply.
The phone's charging circuit (load) won't draw any more current than it does from the stock charger, no matter how much current is available.

Even if our devices were truly capable of accepting an input of 2A, the charge isn't linear; i.e. the charge rate isn't constant. Take a look at this thread to see what I mean! It's a good read for everyone.
Your battery gauge is lying to you (and it's not such a bad thing)

I use the charger that came with my HP Touchpad, which is a higher rate charger than the stock Nexus 4. It does make the phone charge faster, but it also heats it up. I don't use it as my full time charger, but its nice for a faster top up.
Hi,
Since the 4.3 update on my Galaxy S4 I've had a few occasions when the charging does some strange things, i.e. when charging it repeatedly stops charging (as is I'd removed the charger lead) and then immediately starts charging again, this happens every 20 seconds or so.
This initially happened when i was charging from a backup battery but then also happened when I was using a charger which I've been using OK for quite a while.
I also added a non samsung QI wireless charging kit which charges fine but starts the same issue when charging gets to 95%
I suspect the issue is linked to putting the phone on charge when it is already at 95% ish not when at 50%...
I've searched the forum but found any similar issues, anyone any ideas?
Cheers

Sorry, but i am very sure you have damaged USB port pcb. It has nothing to do with 4.3 updating, but maybe it got damaged at same time. Depending of the charger and cable you will get a different impedance value and so that different issues with the charging messages...

Yes but it does exactly the same when using the wireless charging option.

Well all I can say is that I can move the USB connector around when I'm charging, up, down and side to side and there is no loss of charging, I cannot make this happen.
I suppose I'll have to raise it with Samsung, the phone is still under Warranty.

Absolutely correct, the phone doesn't have FAST/QUICK charger technology...
However a higher ampere charger like 2A could still charge a phone faster, hence my query above
Are you sure it takes 90 minutes to fully charge with stock 1A charger as mathematically it's not possible
3000mAH/1000mA=3 hours
Or
3000mAH/1.5H=2000mA or 2A
Pehaps you are using a higher capacity charger? That would explain it...

The time of charging with 2A is the same using a original charger with 1A. The limit is inside at the circuit control of charge.

Yes, you have right.
We can put a 10 A capability charger at our device, but charge control circuit is doing his job and let device charging with 1 A max, even if is there 10 A disposable....
Maybe with some command in hidden menu or with some customized firmware is a way to override this limitation.
(At LG 4X HD is in hidden menu a command that enable fast charging).

I doubt we will be able to find any such software hack to allow fast charging.
There just isn't enough development going on for this phone for anyone to discover and share such information
https://www.androidpit.com/huawei-p9-lite-review
Above review was found by another user on this forum where it's mentioned that phone supports 10W (5V×2A)
So this is what I am hoping is correct and is verified by someone who owns the phone already

That would be really very nice, I would be really happy ).
Maybe fast charge working with another type of charger: Huawei 9V2A Quick Charge Travel Charger
Instead of 5V1A(5W) or 5V2A(10W) with 9V2A(18W) charger, the charge circuit control will sense 9V instead of 5V and maybe switch to fast charge...
2 Amp charger are only needed if you are using a 2 or 3 meter USB wire.

I dont think so.... the options you mentioned actually mean QC 2.0 technology which we know for sure isn't available in P9 lite
There are few mentions of phone supporting 5Vx2A online; one such link shared by me in earlier post...
Read up on QC technology if you want to at below link

The P9 Lite doesnt support any sort of fast charging. The ability of a phone to charge faster depends on it's hardware and the use of a fast charger. However, with a 2A charger, it slightly decreases charging time since the phone pulls approximately 1050mA. Be careful not to use a charger thats higher than 5V as it will fry your circuitry.

Where did you get this 1050mA spec, did u measure it yourself? This could be true as well, as fast charging is not observed by anyone until now except few online sources which state otherwise...
The part about damaging phone is inaccurate as QC 2.0 or 3.0 chargers are reverse compatible with old devices which support 5V only, the phone and charger never switch to 9V/12V/20V mode as the technology isn't there...

I did measure it myself with the aid of a friend. By the way, I was referring to a standard 9V/12V charger, not the QC charger.
According to my knowledge, the voltage is like a gateway to your phone, your phone pulls the current. Hence, if you use a standard charger with higher than 5V, you'll most definitely burn your circuitry. BUT....if you use a 5V charger with an abnormally high amperage, the phone will only pull the current it needs.

Great that you actually measured it, I am assuming using an external device...
That would confirm it without doubt that online reports are incorrect and phone can't charge above appx 1A

So just a quick question.
This means that for a phone to be able to pull 2A, is not just software control?
It means that the hardware has to support the ability?

I believe that is true. Although, most fast chargers (like the samsung one) only supply 1.67A at a higher voltage, normally 9V. This combination increases the output wattage of the charger....Like i said on my earlier post, the voltage is the gateway to the phone while the phone pulls the amperage.
