Hi guys,
1 short question. Do I have to use original galaxy s4 charger or can I use another model from old galaxy s1 ?
It has 1A loading and loads longer but my point is - can it damage my phone by having too litlle current ? As I know the original charger is 2.1A
On the other hand I also use USB port to load my phone and as far as I know it has 0.5 A and loading takes a lot but I don't mind. The question is - is it safe ?
Too less can never do wrong, too much can though.
Me Gusta!

I read an opinion that too little power of charging isn't able to charge the batter to its full and because of that damaging it, but I don't know if it's true.
How about the memory effect ? When I charge with usb port and use the phone at the same time the battery is discharging even though connected. Isn't it harmful for the battery ?
Anything above 600-700ma should be fine, according to the link below for an 2600mah battery at 0.2c is 520ma so give it a bit more for safety, 1000ma should be fine, though the S4 will charge a lot slower.

EDIT : also the usb port on an notebook is only 500ma, and the S4 charges on that as far as i know, i don't have one to be certain.

Yesy my S4 charges on USB but my questions is : does it do any harm to battery ?
And another point : how about using the phone while charging it with too little current ? I have it when charging on USB, the phone just dicharges while I use it. When I let it alone it continues to charge (% going slowly up) , when I turn it back on it discharges again (the % going slowly down) - does it harm the battery ?
Actually a lower slow charge is better for the battery, as a fast charge causes the battery to heat up and heat causes damage to lithium battery`s
So good information on lithium battery care.

Hello all!
I recently bought an i337m S4, and I've got a few chargers around from older phones. I have two that are 0.7A. I'm wondering if it will do any harm to the battery to be charging it at a slower rate? I usually plug my phone in at night, so I was thinking it would be fine to use the 0.7A charger overnight and use the faster 2A charger that came with the phone when I'm on the go and need to charge faster.
So, is it OK to use the slower charger and not harm my battery?
Thanks a lot!
I always use charger that came with the phone. If you want it to charge slower just plug it into a usb port.

No it won't hurt. I use a .7A at work all the time. However it doesn't charge while using the phone so I let it sit and it charges fine.

Alright, thanks a lot! I'll go ahead and use it to charge overnight.
I don't know what drug Apple put in their chargers, but i've always noticed my iPhone charging waaaay faster than my S2.
I even tried draining them both to 0%, and charging them with their original chargers. As soon as the iPhone was full of juice, the S2 was just about 50 or 60%
So i did some research about the safety of using the Apple charger, and it appeared to be all OK.
I'm going to end up buying a new battery anyways because i feel like mine has worn out, so i thought it was a good idea to plug the S2 in the fruitplug.
After i plugged the USB cable into the Apple charger, i immediately noticed the phone charging way faster. Waaay faster.
The phone does get a little warmer, but not too warm. I charged the phone from 8% to 100% in less than a hour!
I'm still experimenting the safety of this, by constantly keeping a look at the temperatures, and how hot the thing feels, and it appears to stay safe.
I recommend to remove your case and battery cover and keep an eye on your phone if you consider trying this, but for now i can say one thing:
If you have an iDevice in your house, charge your phone with the fruitplug
on the other side... what do you think about it? Would you try it?

It is all abouy amp your charger uses.
S2 charger give 5amp out and iphone must be more which throws more juice to ur phones battery thus fast charging.

Not 5A actually, it gives output of 5V and 1A.At least my charger. @domini99, what is the output for your iPhone charger ?

According to the information on the charger, it outputs 1A. My samsung charger also outputs 1A, yet it charges faster with the iPhone charger.
I did some quick research and found that the iPhone charger would have a special sort of **** inside of it that charges the phone in a different way. Not sure if bull**** or actually true, but they did put some sort of magic or drug in that thing to make it hypercharge anything i charge in it
They couldn't have put anything inside, it all depends of voltage and amperage.
You can use charger with higher amperage than your device need though.
And, yea, you can use charger with more amps, but you cannot use charger with higher voltage than 5V.
iPad charger gives [email protected], but last time I tried it with a Samsung phone, it wouldn't charge.
Nightshadow931 said:

The higher the amperage, the faster your phone will charge.
You can use charger with higher amperage than your device need, your phone would charge just fine, only faster. But it would cause heating your device, thus reducing the life of your battery.

Maybe the iPad charger has too much drugs or magic inside of it and your Galaxy doesn't have any Space for it?
tablet/smartphone 5V | 2A,Micro USB
I buy charger for tablet/smartphone [email protected] It charges 3x faster.
I check all the chargers i have with current widget, a nice little app tell how much mv your battery have left and how much your charger putting in. I plug in a 600mah charger and i get around 500-550mah input. With a 2a charger i get 641mah consistantly, so i guess that's thr limit of our device
So 650mah, and a 1650mah battery, that means 2 and a half hour for full cycle. And that also means something is happening to that apple juicer

This.
S2's hardware doesn't allow it to charge more than 650mAh from an external charger. So it doesn't matter if you're using 1Ah or 2Ah charger, it will be the same.
Now, that's for the international i9100, who knows if there's something different with other versions or if the phone has a faulty hardware. I've also noticed that my phone recharges much faster right after being quickly discharged. So it could also be that the metering is faulty and there was juice left in the battery.

I got European s2, would that make any difference?
What I know is that the s2 never will charge over 650mA per hour. I use a 700mA charger and incoming at ~640mA on my s2.
Maybe a battery charger will do better than charging through phone?

How did u make it work ? For me it shows 0mA always. I tried with v0.38 though, could you send me an apk for the latest version (0.40) from play store, cause it keeps telling me that the app is not compatible with my device.
Also, are u on jb or kk ?

I install it from gg play and it works, no trouble there. Im using cm10.1, and i have tp resize the widget to have full vision of it. Anw, just got a ipad mini charger, 1A, plug in and it show around 640mah. 2.5h for a full cycle, that means op's charger have some problem. Too good to br true

A charging dock for the battery only, maybe. But be careful of those, they can make battery "fat" then eventually broke

I dont have a proper charging dock though, i can only guess when it's finish, and that's dangerous. Im using an ipad mini charger now and it's fine, just can do the 1hour-to-full like op's

They didn't disable anything - it doesn't have the Qualicom Quick Charge variant, but it does have it's own variant of a rapid charge.
Using two wall chargers I have here and a Benson certified USB-C Cable, one of the wall chargers support QC2.0 and the other QC3.0. Both charged "normally" reporting on the screen as "Charging".
Using the stock USB-C wall charger that came with my 6P, using EX Kernel and the stock kernel from January 8.1 stock ROM, both reported "Charging Rapidly". I switched kernels using EXKM and a backup of the stock Kernel to test this.
Also, I bought a Tronsmart USB-C Car Charger, and it too reports "Charging Rapidly".

Hey everyone,
So I got my nexus 3 Months ago, I just found out NOW that it is not fast charging at all. I bought a new ANKER charger and wire with it and its just charging slowly which got me really annoyed as I wasted money on it because I thought it had nothing to do with the phone at all. I did some digging around and the maker of franco kernel found out that bloody google disabled the bloody fast charging on the 6P?! What kind of solution is that? I mean they could of at least gave us options on whether to disable or enable it in the phone. Is there ANY way to get fast charging enabled on this phone?

Nexus 6p just charges at a higher amperage then most average phones. As long as you use a charger with 5V/3A you should get charging rapidly. Just remember as the battery percentage increases the amps get lower. Use an app like ampere to make sure your getting close to 3000mA. I think the highest charge I seen on the stock plug was like 2800mA.
Well I bought an ANKER Charger and usb cable with it which definitely says it is fast charging compatible. When it comes to charging my phone I got a small text on my lock screen showing me how much charge there is going to the phone while charging. The average charging mAh is 1,400 and the voltage is 4.3V. I am pretty sure that it has reached a higher charge rate....I'll have to keep an eye on it. Do you think thats an acceptable charging rate?
It's not just about amperage, because some of their chargers are a whopping 8A - https://www.anker.com/ca/products/108/203/Wall-Chargers
Anker doesn't support the variant of rapid charging that the 6P accepts, therefore it only will negotiate down to a normal "charging" rate, which IIRC is exactly what you're getting.

I'm having this problem too. I used to be able to rapid charge using anker usb c to usb c but now it just seems to charge normally not rapid charge.
Anyone know of a fix, let me know.
Thanks
Using s8 fast charger it is rated as 5v , 2a im worried as is dont have lg original charger which supports 1.8a(fastcharge). My phone also got hot on samsung adapter . Should i buy original or its nothing to worry about. Kindly need advice.
AFAIK, there will be no difference. The chip controls how much energy is delivered to the battery, and even if you use a 3a charger, the phone itself will limit the maximum energy delivered so it doesn't affect battery.
It's normal that the battery gets hot on fast charge (even in normal charge) Just try to avoid using the phone or charging in a hot environment so the battery doesn't go further than ~40°C more or less.

The original one is 9V 1.8A so there won't be any problems with the Samsung one.
