I need to charge my hox+ (charging time 3 hr) with any rapid charger
Galaxy S4 charger» Output: 5V»2A
Htc charger» Output: 5V»1A
Can i charge with S4 charger or any rapid charger(high A) or there is a risk?
I need most rapidly mod for charging if there?

The higher mA the faster the battery is charged.However this is not recommended due to the battery life will be affected as well.
In addition :
Your phone would get hotter, and this may damage your mainboard.
Long term usage will affect battery life span .
EDIT: If you have one of those chargers , try charging with it. If your phone gets hot, unplug it as it can damage your device.
Normally, the device (phone) regulates the current while you charge the battery. 5V/1A only says that the charger can supply a maximum of 1A.

i'm reading different opinions about this when i searched through the xda forums and on google.
i'm using the same custom rom and kernel for about a week now. a few days ago, i charged purely on wall socket. left overnight, my battery lost only 2%.
last night, i charged my phone when it was about 30%. i charged using usb up to 85%, then i finished it off on AC up to a 100%. my overnight loss went up to 5% (i did not install any additional apk, or change my setcpu profiles, etc).
there are no topics on this, specifically for SGS2. mostly are from HTC threads.
from what i learned, usb's only pour out about half of what AC's can give (500 mah vs 1,000 mah). does that translate into a poorer batt life?
How you charge your phone, usb vs AC will not effect the battery life, 100% is 100%, it will just charge slower via usb.

I have noticed something similar with my captivate.I would guess that when you use the wall charger with 1amp the battery gets more of a charge than when you use a usb charger at .5amps. 1amp can cause more chemical change in the battery than half an amp.
sent from my Infuse at Tranquility Base.
SGS2 will only let 650mA into the battery, AFAIK it's hardware restricted to do this. Wall charger will charge faster, but only slightly.
I see no difference and 2% to 5% is within a tolerable variation of overnight drain .
Its all the same electricity .

Firmware, actually, and the phone determines how much it will draw based on the resistance between the two USB data pins. If the resistance is < 200 ohms, it assumes it's plugged into an AC charger, and will draw up to 650 mA. Otherwise, it assumes it's plugged into a PC's USB 2.0 port, and will draw up to 450 mA, just under the 500 mA that a USB 2.0 port is supposed to provide, per the USB 2.0 spec.
Since it's firmware, it should be possible to change the current draw by re-compiling the kernel sources with new values. Note that you don't want to go too high on the charging current, as that could cause overheating or fire.

And how about charging a spare battery using a separate battery charger?
I have two batteries and I never charge them plugging the phone, just using a spare battery charger. Does it have any negative effect on the batteries' lifespan?
dont know what happened but my phone is being charged with ac adapter as same speed as usb.(more than 4 hours) :S
I have a USB charger capable of delivering 1A.
Even with the data pins shorted (phone side), it still seems to draw only 350 mA :-(
Any ideas?
Known made-up cables that do work?
Hey guys
I was wondering , since it takes this phone over 3 hours to fully charge... If I buy a Nokia charger with an output of 1.2 mah ,would it take a shorter time for this phone to charge? Its own charger has 0.7 mah output..
No. SGS2 has a capped charge rate of 650 as far as I know.

yes but it might get hot. i used to charge with playbook's charger all was well. but now i use the samsung S2 charger. but i never checked if it was charging faster
Ok, thank you both

Charging is controlled by the phone only and varies depending on whether it detects a USB data link or not. And the battery temperature.
So, provided the charger is rated at 700mA or greater, the phone will charge at the fastest rate it sets. On USB, the charge rate is lower. USB 2 ports have a maximum of 500mA output... and if the phone is on, the charge rate is often lowered further.
I use an iPAD2 charger for convenience, which is rated at 2A. The phone charges fine, but only at the same rate as the stock Samsung charger.

thanks for the info dont know about S2 but i know few brands allow that. blackberry is one of them, using playbook charger on their phones charge them faster but battery gets hot.
I cant find the exact post to link it for you but I'm sure the devs had a discussion about it in the siyah dev thread.
Mains capped at 600 by the device.

Well, I needed more actual facts than technical stuff. So the idea is not to buy the nokia charger cause the sgs2 wont charge faater. This sucks. HTC evo 3d battery charges to full in abou 1,5 hours and it lasts enough so...I really dont understand samsung
In my ROM there is an option to enable fast charging. If you enable that, a charger with a higher mAh will make sense.
Probably the heat issue is the main reason for not implementing a higher charge rate. Battery degradation world be another.

I don't think you should use a bigger charger with a higher voltage to charge your phone, the battery for your SGS2 might not be able to handle the amount of voltage from the charger

Just curious if there is an app or something similar that would show how many amps are being provided when charging through a wall charger/USB powered hub? The reason I ask is that I'm thinking of buying a powered USB 3.0 Hub. The adapter that came with our phone says it's 2 Amp, so I am assuming our phone can pull 2 amps for charging. Just wanted to verify in some way that a 2 Amp dedicated port would really work for this phone.

When I get home, I'll download the kernel source and see if I can find out how much power it draws during charging. I doubt however, that it will draw 2A during charging as most chargers are rated to supply more power than the phone will accept.
Yeah, 2A seems like that could melt a battery charging that fast. Someone sent me a private message and told me to try CurrentWidget. I threw that on the phone and it registers as 1A while charging. But it appears like the widget doesn't break it down with decimals. For instance it could be charging with 1.8A and wouldn't know it. I put it in a standard USB port and it reported as charging with 0 Amps but the battery was indeed charging.
I took a quick look at the N7100 (International Note 2) source posted on Github by CM and it looks like AC charger is 650mA, USB is 450mA. It's a little hard to tell what exactly it's using for charging, so I'll try to verify that when I get home and have a chance to take a better look.

A 3100mAh Lithium Ion battery can easily handle a full 2A charge rate. The ideal charge profile for Lithium Ion is a CC/CV profile, starts at constant current between like 3V and 4V, which most LI batters can take a rate of 1C, meaning it can handle a charge rate of 3.1A, recommended charge rate to achieve the most possible charge/discharge cycles is usually 0.2C so for a 3100mAh battery that would be 620mA. Once the charge gets to the correct voltage it gets to constant voltage and charges until termination current usually in the 100mA range. So yes, it can handle a 2A charge no problem.
Hey there. I very much appreciate that breakdown. Makes me wonder why they dropped the amps so much during charge.

If this is true (first time I've seen this anywhere), that would line up great with the 650mA max charge rate I found. Also, I downloaded the VZW source, and it doesn't look to significantly different from the N7100 source, at least as far as the charger stuff is concerned, so I would say they both probably have a max charge rate of 650mA.
I appreciate the info and time you both put into this. I guess it means a 2A usb port will be slight overkill. Even changing the charge rate to a higher value seems to indicate a lower battery life. Makes you wonder how apple did it's math for the ipads charge rate. The battery must be huge to accommodate a 1.1A charge rate. Or they are sacrificing battery life for fast charging.
Wont the kernel dictate the charge rate no matter what the charger is rated at?
If the kernel is set for a charge rate of 650mA (0.650A), then why does the Note 2 have a more powerful 2A wall charger, while the GS3 has a 1A wall charger.

The original nook color 7" came with a 2A wall charger and that was 2 years ago... both my note 2 and nook color charge about the same rate (quick to 99% and slow to 100). The charger is probably cheaper to make at 2A rather than anything and plus it could be used to charge future devices. Also if you used a 1A charger to charge the note it might possibly get warm/hot from running at near full capacity.
Im using my OLD blackberry 700mA wall charger to charge the phone at night while im sleeping. No problems with heat.
Hi.
The charger we use to charge our s2 gives 0.7 A to charge the battery. But Note2 has a charger of 2 Ampere output.
Will it damage the phone if I use branded chargers capable of giving higher output ???
It won't charge your phone any faster, limited by hardware. But you should be able to use the charger safely.
No it will not work ... I have original samsung charger with 0.7A and with a multimeter i testet it and real output its 1A but while it is connected to phone it charges 0.650(5)A and it cluses touch problems but only while charging
2A will make screen unresponsibile and inacurate and could damage battery

You definitely shouldn't charge with any other charger then chargers made specifically for your phone, it can do nothing or it can make your phone trash, seriously don't take that risk.

As long as the charger is original and not cheap Chinese crap, you are perfectly fine. It is not the Amperage that matters, the phone will take as much as it needs, even if the charger gives less/more. For example :if you use a charger that gives 5v 300mA the phone will charge at 300mA.
If you use a charger that gives 5v 700mA (which I believe is the max the phone can take) the phone will charge at 700mA.
If you use a charger that gives 5v 9000mA the phone will charge at 700mA.
If you use a charger that gives 220v 300mA the phone will blow up.
This to say that Amperage affects just how fast the phone will charge, up to a max regulated by the phone itself. If you give more, you waste the exceeding. If the voltage is wrong, then you will surely have lots of troubles.

Yep. Well explained
Can I charge Xiaomi Note 10 Lite with a standard Samsung charger? Following are the specifications of chargers
Xiaomi Note 10 Lite came with 30w Fast Charger, following is whats written on the charger:
Output 5.0V=3.0A 15.0W/9.0V=3.0A 27.0W/12.0V=2.25A 27.0W/20.0V=1.35A 27.0W/10.0V=3.0A Max 30.0W Max
I want to use the following Samsung charger:
Output 5.0V=1.55A
I don't need fast charging and I am planning on keeping this phone for a longer period of time thus want to use a standard charger to save the battery.
Kindly if anyone has technical knowledge about these readings please advise me whether I can use the above standard charger without damaging the battery if not what standard charger should I buy for my phone?

Thank you but I asked the opposite, I want to charge the fast charging phone with a standard charger. The question was whether my specific charger with 5.0V = 1.55A be safe for my phone battery.
Also to add: the reason I mentioned the Volts and Amperage details is because I don't have much knowledge about it. I remember using a different charger (on laptop) with only slight differences and it caused the battery to bloat. So I need to be sure this Samsung charger won't harm Xiaomi's battery lol
Update: I have been charging 'Mi Note 10 lite' with Samsung Standard Charger (1.55A 5V) but the charger is getting too... hot, not sure whether its affecting battery life (battery is not getting hot) though.
