I've seen mine run up to 43C (109-110F) while charging on OEM LG charger. The battery states do not exceed 40C. What's the highest you've seen? I'm using Battery Monitor Widget.
Highest I've seen is about 34C

What is the amperage on the provided lg charger? I don't have one so I don't know. I think it might be charging at too high a rate. Use another USB charger and see if it is cooler during charging.
When tethered mines been up to 43 before it would reboot on my old hero it could get up to 53

LG charger is rated for 1 amp. I think that's normal for a 1500 mah battery. Last night only went up to 39c.

Hi guys, I was just wondering if anyone knows of a good app to measure how fast your battery is charging while connected to an outlet.
I just got a Duracell usb car charger that says it outputs 2.1 amps, but when I check in settings>about phone>status while charging my phone it says it's charging as USB (slow) rather than AC (fast), so need an app that can show me the rate at which my phone is charging.
Any suggestions?

I don't really know of an app.. But I do believe its the phone that regulates the amount of current to the battery not the charger.

Yeah I know that the phone will only take in what it can, so I wasn't expecting it to charge at the full 2.1 amps or anything but it's bugging me that it says it's only charging as USB.
I just want to make sure it's not charging slower than my other charger (1 amp) that DOES charge as 'AC'.

Gotcha, I use a compact power inverter in my vehicle it has a USB port and a 110 socket. Says AC if charging in either port..

hello
My stock charger is us for galaxy s4 (samsung regular charger)
and then I found this (link above) with 2.1A
is it matter charging via 2.1A and not 2A? what is the different? it will charge faster/slower?
thanks
In Stock kernel there is current limit 1.9A. So everything above it, will be the same as 1.9A.
In reality, you will find that even 2.1A charger doesn't supply even 1.9A. Chinese charges definitely don't supply current thay claim. And beware of them - you may fry your device by such cheap charger.
Also, it heavily depends on USB cable as well. It has to be very short and very thick.
I have a Mediabridge car adapter that has a 2.1 amp charger on it. When I charge my S4 with it it barely charges faster than the 1 amp charger does. I think it charges at either 1.3 or 1.7 amps, sorry can't remember exactly.

How do you measure the exact amperage that it charges at?

I don't have the equipment to measure it exactly. So what I did was charge my phone from 50% for 40 minutes on my stock Samsung wall charger and then recorder the percentage it increased. I then took that number and assumed it was charging at 2 amps and used it as a baseline. Then I did the same test with my car adapter and recorded the results. The I figured out the percentage difference and came up with me estimates. I just don't have the data in front of me anymore but I remembered it being somewhere between 1.3 or 1.7.

The stock charger is fast at charging this phone. On my s3 it took forever . I would stick with stock

Chargers, power supplies, etc, don't "decide" the amps that go to a device - the device "draws" a certain amount. Just because a lamp is plugged into a 20amp circuit in your home doesn't mean 20 amps are going to be shoved through the bulb.
So if, as sorg says, the phone is only going to "ask" for 1.9a, you could plug it into a 5 amp charger and it would make no difference.

You already got your answer above.
No, your phone will NEVER charge faster than 1900 until a developer comes along and figures out how to hack the system to allow this. And it would be a potentiallly STUPID idea to charge faster than Samsung has deemed safe.
Go here to find out how to test your charging rate:

I have note2 right now which have to go. But I'll keep my office charger which is 2A.
Can I safely use it to charge n5?
Sent from SGH-i317m
Using chargers with a high power (A) is no problem, the phone will not "take" more than it needs.
Sorry for the poor english ^^
The issue is if charging IC can handle 2A current or not. I dying wanna fry it lol
I would think it should not be an issue while 2A ICs are widely used in our days, but "better be safe then sorry".

The charging block that comes with the Nexus 5 is 5.0 volt, 1.2 amp.

While AFAIK there's no 1.5A ICs, than its 99% safe to say they using 2A nominal IC.
Thanks guys

If using a different charger was a problem they would have made the connection something other than micro USB.

Not really. Charging current depends on IC installed, not the connector itself.

From what I understand, you could use a 10A charger and still be fine. The handset will not take any more than it needs. Basically, the charger doesn't push current, the phone pulls it.

Thats correct and nothing else. No way to destroy a phone with too much A because it just takes as much it needs. The 2A on an charger is just the maximum power output. It is physical impossible to PUSH the ampere in the device.
What's the side effect of using 2A output powerbank on the cellphone ?
From my experience, the output of cellphone adaptor usually between 500mAh-1Ah. Well, except phone with bigger screen (which i don't have).
What i notice is, the back of the phone are usually hotter compare if i charge my phone using phone adaptor or via usb.
I am kinda worry with this excess heat. Heat is not good for electric components.
It will shorten the lifetime of the battery

What about a phone that's designed for 750mAh and it's being charge with 1.2A powerbank ? Since the common minimum powerbank output are 1.2A.
Even that would be harmful there are 500mA powerbanks available which would be ok

I see. Thank you.
What about the opposite. 1.5A capable cellphone that's being charge with 750mAh charger ?
I think it would be fine. Just the time it needs to charge the phone is longer. What do you think ?
That would be perfectly ok, you're right it just takes longer to charhe

it does not work with my touchpad (HP). If i not charge with 2A output is no charge
Hey guys, does anyone know a tweak where my phone will stop charging at like 99% so that when I charge overnight, it doesn't over charge? Or is this already a feature in many custom kernels such as elementalx

It's a feature of the phone itself. Don't worry about it

With all my phones, I've always left them charging overnight. As jd1639 says - they are designed to ensure they are not overcharged. This is both to protect the phone and also not to waste electricity.
I use an old Motorola charger by my bedside which is rated at 500 mah. As it's going to be plugged in for 7 or 8 hours, it might as well charge slowly! It's better for the battery that way - maybe see if you can pick up a lower-rated charger if you want to be extra careful.

That's actually worse for the battery, being charged too slowly

I've not heard that anyway, but is 500 mah "too slowly"? That's the output you'll get from a USB drive.
Ah right... Just looked it up. If it's an ac wall charger. It's ok. If it's a usb port they generally give out less voltage (around 4.2-4.5) so your battery won't last as long between charges

If the battery is fully charged it shouldn' matter what voltage was used to get there. A full charge is a full charge.

This isn't true. A charger only works by applying a voltage to the cable which causes electrons to flow into the battery. The N5 battery is at full charge at 4.2V. If you're charging it with a supply that is running at less than 4.2V it will only charge up to the voltage applied.
Edit: I guess to clarify I should say that you're right that a "full charge is a full charge" but you will never get to a full charge if you are applying too low a voltage. And keep in mind that if your USB port is only providing 4.2A there is a voltage drop across the wire so you would end up with a lower voltage at the battery.

That's ampage i think. Ampage will gain with charge. Voltage will always stay the same
