Hey guys, can I use a htc charger to charge the s2, I understand the output is different between s2 charger and htc charger, will it pose a problem to the battery?
no problem.
Some info:
A charger does not push a certain current either, the phone uses as much as it wants as long as it is same or less than the current rating on the charger.
And if the charger provides less than the phone wants, then the phone adapts to this as well.
Oki, if let's say the htc charger out is 1.0mah, and the samsung charger is 0.7mah, is it still alright to use the htc charger?

Yes you can just look under your battery once removed on your serial label
Erm.. what to look for?
I only see 3.7V and 1650mAh.
That's all.

No problem.
I'm charging my phone with the following chargers: 1.2A Nokia charger, 1A Nokia charger, 0.7A Samsung charger, 0.55A noname car charger, and some USB cables providing 0.5A.
And I also understand the electrical theory regarding this so this is ok both in practice and theory

The higher the A rating, the faster the battery will charge, but this also will heat the battery more, reducing it's lifespan. Slower charges are annoying, but preferred for battery longevity.
Can I check what A rating is iphone charger? I'm planning to plug in microUsb to charge my s2 at work and leave the stock charger at home.
So want to check again, if 1A charger is suitable for S2?
Just to add on. When I'm charging my S2 using stock charger and playing grand prix story, the percentage of the battery actually decreased. Is it due to the 0.7A supplied by the stock charger?

The phone only allows 650mA? or so into the battery, so anything above that is usually wasted. If you're playing graphically intensive or CPU intensive games most likely the charge rate can't match the drain rate, so slower charging or draining in your case.
S2 only allows 650mA? So even if I have a 1A charger, it won't be able to charge up fast too?

You can use any charger but, from what I've heard, if the output is higher than what is recommended for your phone, the battery life will be reduced.

This is not quite true.
The voltage of mini USB type chargers should always be 5volts. The current rating (amps) varies depending on the charger. Using a charger to charge a device to with a current rating lower than the current rating of the charger will make no difference. However using a charger to charge a device that requires a higher charging current could result it the device taking a longer time to charge and may not fully charge at all.
So most chargers will be fine to charge your phone. However if the charger current rating (amperes) is too low, you may find that if your using your phone while charging you could find the the battery will charge very slowly or even discharge (more likely when using something like navigation app). Both circumstances will make no difference to the health of the battery.
Hi,
I wanted to know if N4 uses battery or only use AC Power.
While is connected to a charger when:
A) N4 status = "Charging, Nº %".
B) N4 status = "Charged".
Assume for this, chargers....like LG retail travel charger 5V 1.2A or a Samsung Car charger 5V 1.0A.
B.Regards.
I'm not sure if this answers your question but I found this true for any smartphone including the Nexus 4. If you are doing something such as GPS navigation in the car and you do not have a charger that outputs enough current your battery level may still go down. Yes, thats annoying. The solution is to use a charger capable of outputting enough ma. I also stick with the chargers included with each of my devices. Ive had too many problems with using third party chargers.
Just food for thought.

I think that always is battery powered. When you are charging, if power in > power consumition then the phone chargers.
Regards.
Thanks! I see....
Do you think 1A would be enough for "Google directions" usage (CAR GPS).?

Stock charger sucks (attach never unplugged charger)
Mmm i just played a race in ASPHALT 7 and my battery was raised from 91% to 94% on Stock LG Charger...
(Maybe ASPHALT doesn't use too much battery? its the heaviest game i have..).
Hi all,
Ok, so I finally managed to order a 16Gb Nexus 4 and hopefully it will be with me in 1 week or so.
And I was wondering one thing regarding the AC adapter: I believe (pls correct me if I am wrong) that the original AC adapter’s output voltage is DC 5V, 1.2A.
I will need an extra AC adapter to keep it at work and I was planning to use one of those:
- The Sony Xperia P AC adapter will output 5V, 1,5A
- The Samsung Galaxy S AC adapter will output 5V, 0,7A
It is clear that neither of those 2 chargers will match exactly the specifications of the original Nexus charger (same voltage, but different amperage).
So, here goes the questions:
1) Is there any problem if I use a charger that will output the same voltage but with different amperage?... if not, which one would you use and why?.
2) how the amperage affect to the charging process?.
Thanks all in advance
PS: sorry for terrible English
You can use any charger up to 2 amps.

You must use a 5V AC USB Adapter and better no LESS than 1A
for Fast Charge.
AC Adapter I Use:
iPad AC Adapter 5V 2.1A at Work
PlayBook AC Adapter 5V 1.8A at Home 1
Original Nexus 4 AC 5V 1.2A at Home 2.
Our Nexus 4 will Draw around 0.8A when Batt lever at 0% - 80%,
then around 0.5A at 80%-95%, Final State 95%-100% will draw 0.2A roughly.
When 100%, Nexus 4 will use the AC power & the Current "A" show on phone
will like 2mA (0.002A) when idling.
** 1A = 1000mA
As previous poster said, do not go under 1.2amp.
I run the OEM charger in my bed room, a USB charger to my computer, and a 2.1amp charger in the car.

Why do you say not to go under 1.2A? Charging from a laptop is at .5A. I've been using a 1A charger since day one. Haven't experienced any issues with it.
Charging at a lower amperage shouldn't hurt anything, just charge slower. All you have to do is make sure it's a 5V charger. Amperage shouldn't matter but a lower amp charger will charge slower. As for a higher amp charger, the phone will only draw the amount of power it needs to charge so using 2A charger won't hurt anything either.
Also 2mA is 0.002A not 0.02 A

Since the charger doesn't actually regulate the charging itself (the phone does this) it doesn't matter how many amps it can supply, could be 100 amps, no worries. As long as it is 5V, the phone will draw as many amps as it needs.
Since the supplied charger is 1.2A rated, it's fair to assume that the phone will never actually try to draw any more than that, so there will be no benefit in going higher.
Going for a lower current charger will likely extend the charge time.
I use a 2.1 amp daily without any issues.

Wow guys!!... thanks all for your answers!!
So, if I understood correctly, the amperage will only affect to the charging time, meaning that by using the Xperia P AC adapter (1,5A) the battery will be charged faster that using the Galaxy S one (0,7A)... right?
Pls allow one last question: a few yeard ago, I think I read in some forums that a slower charging process could help to keep the batteries in the best conditions for a longer time... is this still true with modern batteries??
Again, THANKS all for your help!!

Yes, the .7A charger will take a little longer to charge you phone.
On the other answer, I think NO but I'm not as familiar with LiPo batteries. I would venture to say that .7A vs 1.2A (max the phone will draw but I think someone above mentioned it's even less than that when the battery is very low) is not going to make a bit of difference in your battery life.
One thing I do know about LiPo's is you do not trickle charge them. So while plugged in it will charge at the rates mentioned above until full and then it QUITS charging all together. Once the phone discharges the battery to a certain level, it will charge it back up again. Probably at 98-99%.
There may be one other thing to consider when selecting a third party charger. In the Nexus 7, the device looks for pins 2 & 3 (data) of the USB plug to be shorted in order for it to draw full current. If this pins are open (or have a load across them as is the case with iPhone/iPad chargers), the Nexus 7 will assume it is plugged into a computer and limit its draw to 500MA.
Not certain the Nexus 4 behaves the same way but would assume so.

setzer715, thanks for the answer... I think I will be using the Xperia P charger at work...

I want to make this case clear. According to my Charging log,
Here is some key point.
Nexus 4 Max Draw Rate at Fast Charge Mode is around 800-900mA,
even you use a Charger that rated at 1A (iPhone Tofu), 1.2A (Original),
1.8A (Playbook), 2.1A (iPad).
Fast Charge Mode must be with Charging Cable with 2&3 pin Shorted,
or the charger itself have the 2&3 pin already shorted.
Therefore, 1A is a Sweet spot for getting Charger & Charging Time for
Li-Po/Li-Ion/Ni-MH Batt charging.
If you use under 1A Charger, eg 700mA or 500mA, it will take much longer
to charge the batt but no harm as well. Just too slow only.
The stock charger that came with my phone sucks, I use one from my epic 4g touch (gs2)and it charges much better

Left a phone on a charger all night with a long (10ft) cable and it couldn't even charge the phone over night. I know a 10ft cable will slow things down but my gs2 plug has no problem charging my phone. Search around and you'll find a few fail stories about the stock LG charger.

I have a question regarding chargers and the amps they put out.
While the stock wall charger is a 1amp charger, will a 2.1A charger damage the battery in my Nexus 4? I know 2.1 is usually for tablets, portable gaming systems, but does it damage our cell phone batteries, or just charge them faster?
thanks

2.1A just means it _can_ output a maximum of 2.1A
But the Phone itself will "decide" how much current it draws for charging.
So no need to worry, it will not damage the battery. But it will very likely also not charge it faster.
I myself also used different chargers including the higher amp one from the Nexus 7.
so
You saw no difference in charging time compared to the 1 amp charger?

I did not specifically think about it...I can test some other time right now my phone is fully charged.
But I guess the charger is adopted to the maximum charge current the phone can use.
I believe the phone can pull more than 1A if the charger is capable of delivering a higher amperage

Nexus 4's (from Google):
The input voltage range between the wall outlet and this travel adapter is AC 100V– 240V, and the travel adapter’s output voltage is DC 5V, 1.2A.
And I have another charger that says 5V2A, is it too much or can I charge with it?
How can I know what is the voltage of the iPhone's charger?
Thanks .

It's 5V. Anything USB will be 5V. Don't worry about too much amperage. The phone's internal circuitry will limit/regulate how much juice actually reaches the battery. I use a 2A charger on my Nexus 4 all the time.

So if I will charger my Nexus with the iPhone charger and it is 2A it won't charger my phone faster?
The phone will allow only 1.2A?

It might charge faster. I honestly don't know, nor do I know what the max amperage/speed the Nexus 4 charges with. Heck, I don't even know what the stock Nexus 4 charger was, since I got my N4 second-hand. Come to think of it, I should do some tests, just for future reference. I think I only have .7A, 1.8A, and 2A chargers though (the latter 2 being for tablets).
