[Q] Galaxy S II Charger

What is the output for the Galaxy S II charger? Is it the same as for GSI, i.e. 5V-0.7mA?

Yes its the same.
Sent from my GT-I9100 using XDA App

Also, I have a bunch of 5V - 1A chargers lying around that I use for my Nexus One. Can I safely use them with the Galaxy S 2 ? (I think I can but I want to make sure bedore risking a brand new 600€ phone)

Should be fine the phone should only use the amount of amps it needs

I wonder why it is so weak? Why not use 1 amp as most phones use these days, for a faster charge?

Hi Guys,
Totally stupid noob questions here but mine should be arriving tomorrow from the UK and I'm wondering if my old iPhone USB charge would suffice;
My iPhone charger (http://dl.dropbox.com/u/2119590/iPhone Charger.jpg) reads;
10W USB Power Adapter
Input: 100-240V ~ 0.45A (0,45A) 50-60Hz
Output: 5.1V [weird symbol like a solid line above three striked dotted line] 2.1A
Is this suitable?

Don't worry. There is industry standards, all USB chargers interchangeable with each other. All they have 5V voltage, just current varies. The phone takes current how much it need.

I find mine is charging VERY slowly with USB/AC chargers and some of the Motorola ones I have lying around I can't use the one that came with the phone because it's a UK plug and, well, I'm not in the UK!

The slower it charges the better for the lithium battery in the long run. Search on google.

Find a micro USB charger that can give at least 1 Amper current. PC's USB socket usualy gives max 0,5A and it is not enoughf for normal charging.
P.S.
you can buy adapter like this:
http://cgi.ebay.com/USA-UNIVERSAL-T...259905?pt=PDA_Accessories&hash=item2310799941

I'd go with OEM chargers for the i9000 / Fascinate / Captivate / Vibrant because the OEM chargers have the data-pins shorted which tells the phone to go into AC charging mode. That helps a lot in charge speed because the phone will pull more current.
on ebay they are pretty cheap.

I'd rather it charges fully in 90 minutes and then replace the battery after 24 months, than wait 135 minutes on every charge and replace the battery after 25 months :-/

I got one of these delivered today and it appears genuine and works. No complaints (so far) at £3.43!

I use a what they call a 10Watt charger with 5V USB and 2AMP Current so providing 10Watts of charge. I can charge tablets etc with it and iphone chrages really fats/ but for some reason on galaxy s2 im only getting 3.885V and 641mA current which makes charging really slow on my phone. Thats with lowest brightness setting and wifi/bt/gps/etc off. Is that normal for a galaxy s2 or am i doing something wrong? I am using the revolt 4.3 ROM.

samsung's charger with 2.0A. can i use it for sgs3?

I got an original Samsung charger, looks just like the original charger I have for the SGS3 (same shape, cable & everything).
only difference is the output on it is 2.0A, while the output for my charger is 1.0A.
will it make a difference if i use this charger for my SGS3? just in case it can blowup the phone or something

No problem if the output is Always 5V.
2.0A only means the max power the Charger can send out. If the phone request max 1.0A, then the charger give it 1.0A. No difference in charging time, no difference at all.:good:

Well my fellow Israeli, I'm using 2.0A and it's been great so far.
Bought it in a "private store" and they gave me a 0.7 A charger. So after moving from 0.7A to 2.0A it did made a noticeable difference.
By the way, the 1.0A limit can be changed with a custom Kernel. Such as*Boeffla Kernel.

about the limit change, is it safe to play with such an option? didn't they place this limit for a reason?
but out of interest, how much faster can you make it charge if you change the limit?

Fast charging your battery is very similar to overclocking your cores. If it draws higher amperage and the temperature goes up it will shorten the life of the battery. Slower charging keeps the temperature low and lengthens battery lifespan.
Fast charge w/ High amps = High temps, charges fast, & shortens battery lifespan
Normal charge = Low temps, normal charge speed, & longer battery lifespan
Bottom-line, if you don't mind getting a new battery and want to charge your phone quickly, enable fast charge.

I agree with my friend up above me.
pretty sure that over heating your battery will degrade the battery's chemicals & with time your maximum capacity will decrease.
My personal routine is using another 2 Zero Lemon spare batteries with their external slow charger (0.6 A).
always got a spare in my wallet and it is saved from a possible "memory effect" syndrome which shouldn't be excited in lithium ion batteries, but a recent study by a Japanese guy shows signs of a memory effect.
No idea how much time I save by fast charging. I'll time it next charge for you.

there's no 2A charger for the S3. the one i have was originally for note 2 or something, i forgot. but you can charge the S3 with it...
if you have a regular 1A charger, then don't worry about it, it's the same basically

S3 is coded in the kernel to only charge at 1000ma.
You can override these settings with some kernels, but I wouldn't. Frying charging circuits are quite annoying.

It's for the S4. Note 2 chargers were black like ours.

High Capacity Charger

Just got my hands on the CyberMonday Moto X and I AM PSYCHED!
Now quick question.
I have a Blackberry Playbook Rapid Charger, that outputs about 1.8 amps. The voltages is identical to the A/C adapter from Moto. Can I use it to charge up the Moto X? Or would the higher current damage the internal parts?
My knowledge of electrics is limited to high school science, and subject to chronicle decay over the past 10 years.

No, the phone will only draw as much as it can support. Rapid charging is generally considered to shorten the life of lithium batteries however.

Phone will only charge around 1amp as far as I can tell. One of the things I miss about my s4 is that it charges at 2amps

Spec wise it may say that , but I haven't seen it hit anything over 940mah. Says full charge is 2.5 hours which sounds about right but that's a far cry from the s4 that charges zero to full in 1 hour

Yeah I charge my S4 @ 1.9A and it's done in no time. I know it's bad for the battery but, that's the real benefit of having a replaceable battery!

Thanks, I use that too. But I question its accuracy on the X since it doesn't properly detect my battery's capacity (i have to manually enter it), and often it shows -600mA when running (and not connected to power) even though I can get 24hrs+ out of the charge.
During charge cycles, I've even seen it only show +2mA and +3mA when plugged into AC (and battery is in the 40% remaining).
Right now when I look at it now, its showing +950mA while plugged into the Smart port on my Anker 2nd Gen Astro 3 12000mah battery.
Edit: now its showing +731mA so its all over the place. Not sure if this is the app or the phone.

Does anyone know how well these rapid chargers work with extended batteries like the Morphie or the Zero Lemon?

As long as the charger's output voltage matches the device's input voltage requirement, any charger should work. Then it becomes how much current (amps, or A) does the charger output vs how much current does the device need to charge, which will factor into the time it takes to charge the device.
A few examples:
With a Droid Bionic that ships with a 850mA charger, it will barely charge when using a 550mA (.55A) charger or USB port on my PC. With a 750mA (.75A) charger it takes about 10 to 15 minutes longer than when using the 850. Using a 1000mA (or 1A) charger from my HTC Thunderbolt it charges about 20 minutes quicker than when using the stock 850 charger. Even though using a 2000mA (2A) charger can provide more current, the Bionic charges in the same amount of time as with a 1A charger.
iPad 3. It comes with a 2100mA (2.1A) charger. The 1A charger that comes with my iPhone 5 and 5s doesn't provide enough current for the iPad. It wont charge the iPad unless I power it off, and even then it takes way too long.
The X comes with the 1150mA (1.15A) "duo rapid charger." The X doesn't charge any faster using the 2.1A ipad charger (using a standard micro usb cable of course). And it does seem to charge at about the same speed as when using my 1A charger from my HTC Thunderbolt. While I've used the 850mA charger initially (so I didn't have to replace any of my cords on my dresser), I haven't timed its charging with the 850mA vs 1A.

(sorry about replying to an old post but...)
it says "if you use that kind of charger" the article also says that the X comes with a 850mA charger yet mine is labeled 1150mA output. Either way, an 850mA or 1150mA can't supply 1500mA (1.5A) current.

Did you verify whether the powerbanks energy output is high enough? The HTC "stock" wall charger provides 5V and 1.5A. The powerbank I used for my old One S for example only provides 5V and 0.5A. Since the M9 discharges aproximately around 0.7A while the screen is on (there is a thread somewhere here on xda where someone measured the exact value but I can't find it right now) so weaker powerbanks like my old one may not be powerful enough.

It's working awesome! it's working better than wall charger..

Charging speed

To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the LG G5 can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!

Great Charging
This is the first phone I have had that would actually increase the charge significantly while navigating using google maps in the daylight. And it increases pretty fast.

My Anker QuickCharge 3.0 charger got my G5 from 0 to 100% in ~75 minutes while on. The same charger port got my spare battery in the cradle fro 0 to 100% in ~3 hours (it only pulled 5V).
After lunch today, I plugged it into a USB 3.0 port on my Lenovo T430, and it got from 60 to 100% in under 30 minutes while pulling over 1.2 amps (way above spec).
I'm happily impressed!

As has been discussed elsewhere, QC 3.0 doesn't boost speed much if at all over 2.0. Instead it provides a continuous range of charging voltages (or amps? or whatever) so that it can charge at just the right rate. This should heat the battery less and (in theory, no idea how true/noticeable this will be after a year of use) wear down the battery less because of it.

Screen off = no difference in speed
Try with screen on then 3.0 is 2-3x as fast as 2.0
This has made a massive difference in the car when my screen stays on.
3.0 charges at a solid 1A with screen on as oppose to 2.0 that only musters 0.3-0.6A depending on phone temperature. ?

Qualcomm's Quick Charge goes outside the USB-C spec in order to be able to charge compatible Quick Charge devices faster (higher voltages when possible).
Dose this meet the USB-C spec, no... Would I be concerned about it, Not if I'm using a reputable QC charger and USB-C cable.
Happy fast charging....

I'll be commenting on these cables and QC3.0 charging on my battery charging thread once I have more data. I have 2 QC3.0 USB wall chargers that I'm collecting data on now. These both have USB-A ports, so they need cable adapters.
But yes, early SPOILER @GottZ: The USB-C compliant cables (USB-A to USB-C) with the resistor limit the benefit of QC3 over QC2. But @stuart0001 does have a point with charging with the screen on.

I look forward to your findings.
After further experimentation, QC 2.0 will hit 1A with screen on when below 32deg. So I've found when screen on:
QC 2.0
<32 = 1A
32-35 = 0.6A
35-42 = 0.3A
>42 =? (I haven't tested yet)
QC 3.0 maintains 1A, certainly upto 42. Again, I've not tested higher than that.
This is all with the cable that came with the phone.

when talking about QC 2/3 you should also mention volt or just combine volts and amps to watts
just talking about amps is like saying A: has 2 inches Ampere and B: has 3 inches Ampere
