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 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.

so i lost my fast charger which i didn't didn't use anyway as i kept fast charging unchecked in phone settings
now i got a new romoss charger which is a good charger AFAIK. it is rated at 2.1a, plugged it in and it took too long to charge. i downloaded an app called Ampere to measure the current and the maximum it gets is about 1000mA.
i thought the new charger was ****ty so i tried my friend's LG charger 1.8a and got the same results. tried another 2.1a samsung charger and nothing exceeds 1a.
is it something wrong with my phone or is it software related?
i'm using eRobot's newest rom with spaceX kernel (also tried googymax and suemax kernels). tried to check the fast charge option and again, same results.
any opinions or thoughts are much appeeciated
thanx
You need a Qualcomm Quick Charge 2.0 compatible charger in order utilize adaptive fast charging on your Note 4([email protected] & [email protected] output). Buy new Note4,Nexus 6,Motorola X Style charger. Also make sure your USB cable is undamaged/good quality, since not all cables actually support fast charging.
i dont need to use it as a fast charger, i just want it to charge with 5v 2a which the chareger is capable of
My device is taking more time to get full charge. Is anyone experiencing the same.is there any way to improve the charging
My device is taking around 3 hrs to charge fully which is quite normal as given it has 5000 mAh battery and no fast charging. Only way to improve could be to switch off and then charge or not use phone while charging. Disabling cellular data and WiFi may also help.

In my first time charge, i leave it charging when i sleep, but when i wake up my phone just have 82% battery, it takes 7 hour charge when i sleep, i realize that my mistake was not plug in perfectly the usb cable to charger adaptor, shame on me LOL
When it plug perfectly the charging time may 2,8 - 3 hours to 100%

Does it show "Charging Rapidly" state on the lock screen?
On my Anker triple ports QC2.0 charger, 2 of the normal ports 5V2.4A are able to "induce" my M2 phone to go into "Charging Rapidly" state. It only happens after plugging in for a few mins; if plug into the QC2.0 5V2A port it doesn't display "Charging Rapidly", just shows the normal "charging". Another of my QC3.0 charger 5V3A is also able to do this while other chargers I tried from 1.8A-2A range can't get this "Charging Rapidly" state. Is it possible that the M2 only support "fast charging" on 2.1A and above chargers?

No... Actually the speed of charging also depends on the current... If you current is 2A, then it automatically shows charging rapidly...
If you use any other charger with a lower ampere rating, then the phone will automatically detect that the current is low and it is charging slower...

Its just a suggestion... Dont use the S5 charger even if it charges faster... It voltage is 5.3v ... Voltage should always be 5v ... It will destroy your battery in the long term...

Why do you say it will heat up a lot? Phones nowadays should have protection circuit to limit current, right? For my M2 I don't see any difference in using 5V2A or 5V3A adapter.

I might be wrong... Of course they have protection circuits ... I have another phone Galaxy E5. It also should have a protection circuit or whatever...
Its charger is rated 5V 1.55A... But when I use a 5V 2A charger, the phone starts heating up...
Though it happens only while charge is less than 100...
Upon reaching 100% it cools down...

Did the voltage of the other charger n default charger are same? U can check it by the body of charger itself. Its state there..if that the other charger are lower voltage then its make sense if it slower than the default charger.
