[Q] Working replacement charger (normal or car) for Galaxy S with more than 500mA?

Does anybody know a really working replacement charger for the Galaxy S?
I have tried different models but all are not recognized as original charger so the Galaxy is only charging with 500mA.
The Galaxy S does somehow check if it is an original charger and only than switches into charging mode.
You can easily verify this. Just connect your phone with the charger, open the task list. If you see the USB choices menu the phone is in PC mode and only charges with 500mA.

2000 mAh (2A) charger
http://www.dealextreme.com/details.dx/sku.25177
this if you like windshield mount
http://www.dealextreme.com/details.dx/sku.42602
or this if you like air vent mount (i tilt it horizontally, it's more secure and works better with SGS)
http://www.dealextreme.com/details.dx/sku.37823
it actually can use both, vent and/or windshield

So you use this charger and it switches the SGS to charging mode. That is good news. All chargers I tried only charged with 500mA alltough they were stated with 2000mA or 1200mA.
How long does it take to fully charge the SGS?

that's the one i use in my car, charging varies depending on use
on short drives it will keep your battery from draing (unlike the 500mAh ones)
on long drives like at least an hour or two can charge a few bars meanwhile keeping GPS on, Bluetooth On, 3G/H data On, Screen On
on long road trips the battery will be fully charged.
but if you were using a 500mAh your battery will be completely sucked dry, on 1000mAh it can keep everything running, but battery might not be at full

Does anyone know why the standard Samsung charger outputs so low? :S
I'm just wondering if they did that for a reason like the phone can't handle too much power

it's rather cost cutting, all phone chargers i've ever had from included items were always around 500mAh

The mains charger I use seems to work the same as my official one
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=300435855427
My car charger comes up with pc mode though which as you say probably means it isn't charging properly (I notice that the charge is about the same when I finish my journey as when I started if I use gps)
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=370391436219
Is there a way to tell how well it is charging? I'm guessing if it thinks it is connecting to pc then it won't charge properly

you can use a battery app to monitor the mAh in the battery
if it charges as you consume, then the mAh should keep going up
but if the mAh keeps going down, then the charger is obviously not providing enough power

Unfortunately not really.
There is an widget (http://forum.xda-developers.com/showthread.php?t=723217), but it is not working for the Galaxy.

yes can someone post a decent charger and car charger (preferably on ebay) that charges at a faster rate, the supplied usb cable takes forever to charge my i9000!

I use a mUSB car charger made by Rocketfish (Best Buy brand). Works well, doesn't show "USB Plugged". Was charging pretty quickly even though I had GPS on and Navigation running, which drains battery pretty quickly normally.

I'm using the original charger on a US Vibrant (700mA) and I can still see the USB choices menu.
Is there any other way to check on how much current the Vibrant is using to charge? I have a 1A car and wall charger, but there is no way to tell if they are using 1A or not.

i'm using a max output:1.0A charger works fine. It is a power supply from my old phone which is an adapter with a USB port so i just plugin the galaxy's usb cable and charging happens very fast.

Did you try this in your car with the screen on full brightness and running GPS software? Important to note because all of these chargers work fine when the phone is sleeping or even idling, but when you throw in full screen brightness, tax the cpu/gpu with software, and use the GPS and radios for triangulation for location data, thats when the power consumption overwhelms the charger.

There's some good information on measuring amperage usage of different chargers in this thread in the Vibrant forum:
http://forum.xda-developers.com/showpost.php?p=7704900&postcount=15
Apparently you can read the current charge your phone is pulling by going to this file on your phone:
/sys/class/power_supply/battery/batt_chg_current
So under the same load conditions (screen brightness, GPS enabled, GPS software running, approximately battery charge level) you should be able to compare how much amperage the phone is able to pull on any given charger.

So is this with the 2000mah charger you linked?:
http://www.dealextreme.com/details.dx/sku.25177
Could you give us some measured numbers, that would be so helpful!
Does anyone know if our phones will stop charging when the battery is full? Do we need chargers with IC chips or will the phone take care of it? I mentioned this in the vibrant forum, but my old dumphones required smart chargers as dumb quick chargers would keep charging away killing the battery, but my Dell Axim PDA was smart enough to shut off charging when full itself.
I'm thinking of getting the 2000mah charger linked previously, but I'm concerned because I haven't been able to determine if it has an IC chip in it, but I don't know if we even need that with our phones.
If we need smart chargers im considering this:
http://www.dealextreme.com/details.dx/sku.40470
Someone in the reviews measured it at 1.1amps and noted it has a decent IC chip.

Android automatically stops charging if it THINKS the batter is full
see this topic
http://forum.xda-developers.com/showthread.php?t=722862
it's more of a nuisance than a good safety feature
also in another topic we found that if your phone is bricked, it will not charge the battery, because there is no OS to handle the charging.

Thanks! Looks like the phone regulates charging itself, and works well enough so long as it doesnt get out of calibration (by you flashing the phone when not at 100% =D) Do you happen to know if it will continue to regulate and stop charging even when the phone is completely turned off? I guess the question is if the android system in charge of this still runs when the main OS is turned off.
Otherwise, for the purposes of our thread, looks like using a 2000mah quick car charger without a verified IC chip should be fine!

As far as i know the 2000mAh charger that I'm using has a build in IC chip (most car chargers now in day has one) as well, but it's hard to tell, unless we can remove the auto safety feature of Android in the SGS.

well you could crack it open and see whats inside =P but I don't that is necessary since we're covered either way, our phones can regulate the charge regardless.
Thanks!
btw i would still LOVE it if you had a chance to see what value you see in /sys/class/power_supply/battery/batt_chg_current when using the 2000 mah charger.

5v 1000mA charger

Would it be safe to charge the batter at 1000mA compared to the stock 700mA the charger provides?

yes, i do it all the time

I use the charger from the Galaxy Tab all the time, it's rated at 2A and the S does see it as a proper charger. I've not checked, but I also think it charges the phone faster than the stock charger.

yes it does
the higher the Amp, the faster it charges
however this is not compatible with all phones
the SGS is a good phone, my Motorola will not charge if you exceed or you are under the original charger spec (which is totally stupid) but i understand it is to protect the phone, from over heating
SNS also accepts higher output chargers

So can I use this ?
actually it is ipad charger, 5.1V 2.1A output.
On the phnoe label it is printed max~1000mA
but this is 2.1A.....(2100mA)
it seems too high...

The battery might heat up to a high temp and if done regularly it could very well shorten the life span significantly.. the stock 700mA charger makes the battery warm, Im guessing that 2100mA will make it very hot, but you can try for like 30mins of charging see if thats the case.. if you can just say its warm then I would presume its safe.
700 to 1000mA charging has very little difference on the warmth that i feel from the battery.

If you have the International Galaxy S GT-I9000 it won't charge any faster than about 450mA regardless of the charger rating (from my tests). You can get a higher-capacity charger but it won't make any difference and is quite safe so long as the voltage is correct.

The International Galaxy S I have comes with a 700mA charger though, there is a noticeable charge difference between a USB port (500mA) vs the stock charger (700mA) and my 1000mA charger

If 2100mA is also supported, the charge time will become in just 43min (in theory).
And if the charge circuit is safe enough, it will control the current to 700~1000mA, and it will drive below 200mA in the beginning of charge.
Just try plugged to my phone, it is charging as USB not AC,
so I think the currect will limit to 500mA.....
will try again later, my battery is still full now.

If theres a 500mA limit why do I get faster charging speeds with the wall charger compared to the USB ?

That's the question..
I'm using data cable, so the phone just detect plugged to USB i/o AC power.
maybe I need to use straight miniusb power cord.
Then it will really challenge the phone in 2.1A
On the other hand, IP4 & Ipad can draw 1A from computer USB, (need new motherboard)
what about Galaxy S !?
I will test it later.

If the charge time is less than one hour,
you are getting benefit of high current.

In relation to what you said that IP4 and IPxD can draw 1A, thats why I said the USB 2.0 spec is only 500mA so those devices cant draw more than 500mA on a USB port.

IP4 is USB2.0 Device,
plug into high power USB port (that is USB3.0 port)
USB2.0 IP4 can draw over 500mA
I know what you mean, if the source is USB2.0 of course you can't draw higher than 500mA.
My point is, if the device can draw higher than 500mA, just like the usb2.0 IP4,
and if galaxy s can draw that high,
then we can get benefit from the high output usb ports and also that high output usb charger.

Hello everybody,
I want to share my experience.
So I have a Samsung galaxy S, and usually I charged it with the original charger (700mA).
I tried with a 1000mA one. The charger was really faster than with the original one. So I thought that if I buy the galaxy tab's charger (2000mA) it would be faster.
It's what I did. But the problem is that it's not faster with this one than with the 1000mA one.
I think the problem comes from the USB limit of charge (1000mA in a outlet, 500mA on a USB port from a computer).
But I have a problem with this... I mean, the galaxy tab is charged by an USB cable too, even if it's not the same plug out (I don't know the name of this plug out, I know on the galaxy S it's a micro-USB) on the cable, it's still an USB cable. So why this USB cable can give 2000mA while it uses an USB technology ?

it's definitely faster charging on a 1200 nokia charger..

I can't help myself and I must tell you guys something. The mA of a charger means how much current it can provide in 1 hour, imagine it like a pipe through which only a ammount of watter can pass. Now going back to the phone... We have a 1500mA batt which means that if we use a 25000mA charger it will only output 1500mA... So it is useless to use a more powerfull charger than 1500mA. I hope you understand what I said

That is a 1500mA*h* battery which means capacity and not current.

[Q] Voltage on unofficial micro USB charger

My GF ran over my mains charger cable with the vacum cleanerr at the weekend, so i ordered i new one from Ebay. Rather stupidly (as an "official" one would only be £1 more), i bought this unbranded one:
UK MAINS CHARGER FOR SAMSUNG i5700 i9000 GALAXY S on eBay (end time 02-Apr-11 14:51:41 BST)
When it arrived i noticed that the output is different: 5.5v 500ma as opposed to 5v 700ma from the one that came with the phone.
I know tha ampage will affect charging speed, but am concerned about the extra 0.5 voltage. Is this safe to use?

I'm curious about this too... I thought the "U" in USB meant Universal.
I just ordered 2 micro USB chargers from Ebay for my GF's Sony Vivaz Pro and my Captivate... neither work.
Her's doesn't recognize the charger at all... mine beeps and says "charging", but the battery level never goes up.
My chargers are 5v 500mA.
The chargers were listed as Blackberry chargers, but had a long list of compatible phones underneath (none matched our phones, to be fair.)
Now I'm afraid to buy any more generic chargers....

I don't know if the output voltage is part of the USB standard or not. I know that computers output 5v and it seems like a lot of phone chargers also do. However, i've seen some external battery chargers listed as compatible with the SGS listed as 5.2v, so maybe theres an accepted voltage range? Does anyone know for sure if a 5.5v is acceptable?
I'm not sure why the ones you have don't work as the specs seem right,possibly they are faulty?

Yeah, I'm not sure. I certainly thought so, even though it seemed pretty "unlucky" they both might be faulty.
I did ask the seller, and they claim they are NOT compatible with my phones, but I just don't get it. They're offering me a refund, but at $4 each it's hardly worth my time mailing them.
I found some forums online of a small handful of people like me with chargers that won't work. It seems people with this issue were using 500mA chargers, and anyone using a 700 or 1000 had no problems. This wasn't necessarily because all phones either require 500 or 1000.... Someone also said it's only very certain phones that are built this way. That they require newer, or more powerful chargers... but that it's not the case with all new phones/smartphones.
But there were others who said 500 should charge it, just more slowly.
I still think Micro usb is Micro usb, period. That's why the EU (and here) have been looking at making these chargers universal. I think I'll just try my luck again with another charger.

You could try this one, which claims to be (and looks like), an official SGS charger:
http://cgi.ebay.co.uk/Samsung-i9000...ories_MobilePhoneChargers&hash=item2c5b2d355a

5.5V is supported. I've tested a very wide range of chargers for my SGS and all worked.
The voltage range of these chargers is 4.8V - 5.6V and all worked just fine.

I've actually got an original Nokia USB charger which is declared at 5.0v/550mA and it works like a charm...
Model is AC-6E:

Well finally decided to give the ebay charger a go. Plugged it in, a green light lit up and plugged the phone in. The phone didn't recognise the charger, no indication the the notification bar that the battery was charging. Unplugged it and and tried again, and now the light on the charger doesn't even come on! Won't be using it again.

Another question on the topic : Is it save to use charger with higher Amperage ?
I mean original samsung one is 0.7A, could something go wrong if I´ll use 1.0A charger? Thanks
EDIT : Answer no needed anymore - found it in another topic. It should be safe

I believe any microUSB charger will be safe. Ideally, you want the highest voltage and highest current possible.
I've heard that the phone will use the data lines to tell the USB charger what voltage to set. This ensures voltage compatibility. Then the phone itself regulates the current.. it will only draw as many amps as it needs. So if the PSU can handle 2A, your device may only draw 0.725a for example, but it's safe. You want a high current one to ensure the phone has all it can take.
BTW, I'm not an EE person, so double check what I said.

I fear it's not that simple, especially with dumb chargers that can't negotiate current using the USB protocol, and instead may short the data lines, in various ways, instead to tell the device what current to draw...
Sent from my GT-I9000 using xda premium

There's an explanation here of why different chargers do indeed make a difference:
http://en.wikipedia.org/wiki/Usb#Power
see in particular the note on the Battery Charger Spec.
In particular. my own testing shows I can go from 500ma to 700mA charging current simply by changing a small connector in line between the 7Ahr battery I'm using to charge the phone, and the phone. That's due to the nature of the short on the data pins.
There are proprietary tweaks to this mechanism; e.g. iPhones use voltage signalling between the two data lines and ground to indicate various things to the device.
All of this is only for "hosts", i.e. chargers etc, that don't implement the USB protocol and so can't engage in the normal current negotation that occurs when connecting e.g. the device to a PC.

It's a bit too high.
You have to know that slow charge = long battery life and fast charge = more battery drain after a couple of years maybe months

Maybe because the current is higher. My battery voltage is arround 4200mV at 100% and 4100mV with USB
For the solar charger 5.8 is really high but the wall charger is ok

guys can anyone tell me what would be the reason that my Samsung j7 prime charger is giving me 4.63v instead of 5v .. the rating is 5v on the charger. is that possible the ic or some other thing is damaged? in that case what would be solution?

USB vs. AC Charging and battery life

A few days ago while driving home from work, the TB tells me that even though it is connected to a USB power source, it doesn't have enough juice to keep on going and that I should switch to AC power. I was rarely (if ever) using the AC adapter. I always plugged the phone into a USB port on my home/work computer or into the dual USB adapter I have in my car. I started charging with the AC adapter at night and noticed a significant improvement in battery life.
I can't really say that the power source was the key factor, since I was experimenting with kernels, ROMS, and SetCPU profiles/smartass governor on a pretty consistent basis. In any case, I'm pretty sure it made a big difference... something did, anyway... I can easily get through the day now.
Then I stumbled on a dual-USB-A to mini-USB cable from a 2.5" Antec HD enclosure and figured I'd give it a shot (with a mini->micro adapter). It was necessary for the enclosure when you tried to use a 7200 RPM drive because a single USB port didn't deliver enough power alone. I decided to plug in my old Droid and see if it worked. When it did, I crossed my fingers and plugged in the Thunderbolt. Seems to be running fine. I've been taking the cable with me between my car, home, and work computers and have noticed faster charge times, less of an immediate drop-off when disconnecting.
I found what appear to be the same cables online if anyone is interested in testing. They are made by StarTech and compusa.com apparently has the cheapest prices (~$4/ea). The part numbers are USB2HAUBY1 / USB2HAUBY3 / USB2HAUBY6 for the 1ft/3ft/6ft respectively. I'm wondering if anyone else could try my experiment w/a more stable platform (i.e., not changing ROMS/kernels/etc.). I figure now that the initial "I can't stop playing with this phone" phase has worn off, we should be able to measure the difference with more typical usage patterns.
FWIW, I have no intention of ever using a single USB-A to micro-USB cable to charge this thing again (except w/the AC adapter). Anyone charging via USB should definitely consider it.

LOL I just started a thread about this here: http://forum.xda-developers.com/showthread.php?t=1022400 not 6 hours ago! Nice to know the cables would work. I figured if I ran two in paralell it might do the trick.

Weird, I've yet to have a cable that told me it was not strong enough.. Multiple cables used in my car (has a usb port), home and work computers. Guess I've gotten lucky.

thats interesting, i kno for sure that using a/c is by far the best solution as it lasts longer, stronger charge, and charges MUCH quicker, i usually only use regular usb as a last resort, but i think u made a pretty damn good discovery! im definitely looking into this

The chargers that came with the phone are 1Amp supplies... Standard USB is only .5Amp, so far 1Amp is the largest draw on a USB 2.0 standard... While when USB 3 hits, that will have higher current capacity than 2.0, so it looks as HTC has designed the phone for USB 3.0

I don't remember what the exact error message was, but I was at about 7% when I got to my car... I tried to use the phone for navigation and after a few minutes it told me that I needed to switch to AC power.
My thinking is that when the phone is running, active, and the screen is on, it is drawing too much power from the USB power source to allow the battery to fully recharge. This is probably why my experience with the battery has been abysmal. I was using a single USB cable plugged into my computer or a cigarette/USB car adapter 90% of the time.
But if the AC power supply pushes 1A and each USB port can push up to 500mA, the Y adapter should come pretty close to matching the performance of the AC adapter. I'd guess that AC would be the best option, but I'd prefer to have the USB connection w/the computer.
Sorry nerozehl / mods for not adding onto another thread, but I wanted to get the poll going to see how people are typically charging.

Sounds like you have Power Save set to ON for the error message...

Due to my crappy battery life I use this method.

very often when using your car charger and navigation, the phone uses more battery than the car charger can replace, so the battery will drop even while plugged in charging. a imagine USB would be similar, since usb is 0.5 amps, while A/C is 1amp. i went to radio shack and got a 1.3 amp charger for my phone, and when plugged in in my car it pulls around 800mA during charging. so its just about close to good enough.

Now you risk the overcharging/overheating...Keep an eye on that temp

I don't remember what the exact error message was, but I was at about 7% when I got to my car... I tried to use the phone for navigation and after a few minutes it told me that I needed to switch to AC power.
My thinking is that when the phone is running, active, and the screen is on, it is drawing too much power from the USB power source to allow the battery to fully recharge. This is probably why my experience with the battery has been abysmal. I was using a single USB cable plugged into my computer or a cigarette/USB car adapter 90% of the time.
But if the AC power supply pushes 1A and each USB port can push up to 500mA, the Y adapter should come pretty close to matching the performance of the AC adapter. I'd guess that AC would be the best option, but I'd prefer to have the USB connection w/the computer.

Turn off 4G and drop the screen brightness to 50% orless and the draw should be low enough for USB charging. If you are using a car adapter, get one of the high current ones that output 1A. You can get a nice widget like 'Battery monitor Widget' which will show you if your charger is keeping up or not. If the widget displays a value that is green, the charger output is exceeding the draw from the phone by the value shown in the widget.

No need to worry, battery only draws what power it needs, anything higher just doesn't get pulled. Been using it a year now

Xiaomi's latest 10000mAh power bank offers USB Type-C for $22

http://www.androidcentral.com/xiaomis-latest-10000mah-power-bank-offers-usb-type-c-22
And the big Q... will it rapid-charge the Nexus-6P.... anyone?

I´m not sure if this Power Bank can charge the Nexus 6P fast ( 5V @ 3A ). I´ve tested a iVoler 10000mAh USB Type C Power Bank before and this one works great with the Nexus 6P.

The Xiaomi is much much smaller...

Quick Specs:
Input Voltage : 12V/9V/5V
Output Voltage : 12V/9V/5V
Input Current : 12V 1.5A/9V 2A/5V 2A（TYP）
Output Current : 10180mAh/39.19Wh（TYP）
Rated capacity : 3.6V/10000mAh(TYP)
Size : 128.5*75*12.6mm
Load detection : Auto-detect the plug-in and plug-out of devices
Weight : 223g

seems like it could only charge at 2A for 5V

No. I just received it today, and the usb-c interface is for charging the battery only. The legacy USB interface is said to support fast charging, but it didn't when I connected it to my Nexus 6P; it charged the phone at normal speeds.
I suspect the advertising around "bi directional usb-c" means simply you can plug the cable in both ways, and "fast charging" means you can charge the *battery* quicker.
In fact, if you connect the battery and a Nexus 6P via a usb-c cable, the phone starts charging the battery!

This is true on many (all?) batteries that allow you to both charge or discharge on the Type-C port. You might have to push the power button for the phone to start charging. What happens if you unplug the Type-C cable, push the power button on the battery, and then plug the Type-C cable back in? Does the phone start drawing power from the battery instead of charging the external battery?
IF the phone starts charging itself from the external battery, can you please let us know how much power is being delivered per the Ampere app? I'd be curious to know this. I couldn't find anything on Xiaomi's web site that gave a definitive output current number.

Nope, pressing the button on the battery makes no difference (before or after being plugged in to the phone). The USB-C port is purely for charging the battery, not for using the battery to charge other devices.
I've attached a scan of the booklet that came with the battery. You'll need to read Chinese (I can't) to understand it though. 2 colleagues have told me it explicitly says only the legacy USB port can be used to charge other devices.

That stinks. Thanks a lot for the heads up, I was considering buying one to compare to the Orico battery.

the part that says USB接口(输出) means USB port(output)
the Type C接口(输入) means Type C port(input)

Argh... I wish I read this thread before I purchased this. I can confirm that the USB C does not output a charge. Really disappointed as all the reviews I've read led me to believe the USB C port was both an input and output. I've attached a screenshot of what I'm getting per Ampere. Oh, and I know this is in the Nexus 6P thread, but I'm actually using this with my Nexus 5X.

I cant find the Xaiomi on any website

I fell for the same ****. I got mine today for $60 AUD, the only reason i paid that is there is no power banks in Australia that support USB-C. The USB-C port is only for charging the power bank, you can also charge the power bank using your phone. Xiaomi mi 10000mah doesn't rapid charge.

I'd assume so, Chinese only instructions. I'm on a tab at the moment, can't view the pic.

Hi guys, sorry for the UP but I bought the power bank today and I run into your same issues.
I saw a video (in bangladeshian, LOL) that actually from Type C port you can fast-charge the Nexus 6P, and also if the phone is off, it starts to get fast-charged by the battery via USB-C.
So basically, is there a question to disable "Nexus power output"? This way the USB quick charging should work fine.

Damn , maybe because it's usb a to C , so the Ampere really low

This powerbank looks quite nice but it doesn't support USB Type-C Fast Charging. It only supports 2.0A output so it won't charge the Nexus 6P or 5X at full speed . Looks like I'm gonna be looking elsewhere.

The usb-c port is for charging the power bank only. It does not rapid charge.

According to people in this reddit post it quickly charges the Nexus 6P if you use a different cable than the one it ships with. Only from the USB-A port though.
https://www.reddit.com/r/nexus5x/comments/49xj4c/just_got_my_hands_on_the_xiaomi_10000mah_mi_power/

I bought one as well.
It does NOT charge via the USB C port, it is only an input port.
So no quick charging with it unfortunately.
