Chargers that don't trigger wake locks - AT&T Samsung Galaxy S II Skyrocket SGH-I727

From the thread in general, it looks like many chargers will trigger wake locks in our phones:
http://forum.xda-developers.com/showthread.php?t=1759541
I thought it would be good to have a thread that lists chargers that are known to work with our skyrockets, and don't produce the wake lock issue.
FYI- in the thread above, there is a link to another thread that has an App you can use to test your charger:
http://forum.xda-developers.com/showthread.php?p=29451951#post29451951
I've used the app to test a number of chargers that I have, and the following work well (i.e., type 2= AC Fast Charge. AC Fast Charge. There is 5VDC on pins 1&4, and pins 2&3 are BRIDGED):
Stock Samsung charger (duh)
HTC Inspire 4G charger
AT&T U2800A - GoPhone charger
For car chargers, unfortunately, all of mine produced wake locks. So, I'd like to see if anyone knows of good car chargers that fast charge and don't produce the wake locks. I looked at the Samsung ones, and from what I read, they are 700 mah, and not the 1A chargers would be preferable if you are trying to use GPS, etc.
Feel free to add your known chargers here. Maybe this can be made a sticky if we get enough responses.

Update: I had a chance to check the charger in my wife's car, which is a HTC- Mobile My Touch 3g charger, and it works correctly. Just bought another one for my car.
Here is the link at amazon:

Nice, the charger you posted also charges up to 1.0 amp, just bough 2.

I'm surprised more people haven't chimed in on this. I tested my girlfriends iGo charger and it doesn't produce a wake lock.

Other chargers....
HTC MyTouch 4G chargers
Just Wireless 1.0A Wall Charger (Target and WalMart)
Just Wireless HTC, Motorola, and Samsung Car Chargers
Or....
Buy the Just Wireless USB Universal Charger Cable ($15 from Target and WalMart) and use nearly any charger that normally causes wakelocks, including:
- Apple 5W (1A) charger for iPhone/iPod
- Apple iPad charger
- Griffin Wall chargers
- Most 1A car chargers
and much more
I'm using the USB Universal Charger cable and I'm able to get Fast Charging (AC) out of it with my Galaxy Note i717 combined with my iPad chargers.

Ordered 3 chargers off of ebay, none work

Ordered a universal one with wall attachment and car attachment and when I connect the USB to microUSB cord the phone doesn't charge. Ordered another stand alone car charger and it, also, doesn't charge. If I attach the USB cord that came with the phone to the wall/car charger it charges fine. Both, specifically said for the "Nexus One". Is it an amp issue? Most microUSB charger in the mall cell phone kiosks won't charge it either. Is it a proprietary microUSB cord that I need or a matter of amps or something?
Why not buy from Monoprice.com?!
I ordered 8 USB cords (2/each of 4 different lengths), 2 Car Chargers, and 2 Wall chargers. All work perfectly fine, and I paid under $25. (Wife has a CLIQ, so we got plenty to work for both of us.)
So, I don't know what your issue is... Other than just not going to Monoprice

well I havent ordered from monoprice since customers got slammed with bogus charges... i guess i could give them another try though, but still... kinda weary
Why? I had over $1300 attempted to be spent at Newegg, and my CC company called me and stopped the charges. Got a new CC in the mail the following day. Some random amount at Apple as well. LOL. Fun times.
(Yes, it happened to me. I'm fairly confident it was from the same issue as others..) But, that doesn't stop me from using a company that makes good products, expecially when they just made such a big mistake. Odds are, it won't be happening again for a long while
Either way... Those are risks with online shopping. You just have to make sure that your method of purchase has fail-safes.
I have a CRAP load of mini USB chargers (all HTC stock) and didn't want to buy more. I bought a bunch of Motorola mini to micro adapters off Overstock.com for $2 a piece and couldn't be happier. I also bought the official Google cradle to avoid additional wear and tear on the microUSB port.
-Mc
I bought a car/home charger from eBay when I had my Motorola Cliq, and my home charger would keep going on/off charging. I later found out that it was the voltage issue, where the charger was giving a maximum of 5 amps and the Motorola Cliq needed 5.1V or something like that.
But most chargers I've bought don't power the Nexus One. What specific voltage or amps should I look for it to have? The two I bought off of eBay specifically said they were for the Nexus One. Neither worked. Sellers are putting any micro SD chargers up for sale assuming they will change the phone. They will not. What technical spec will tell me if it really will charge it?
Could someone post a link to a USB charger that absolutely works? I just bought another one from Best Buy that doesn't charge the Nexus. Made by Rocketfish and is suppose to be universal.
Thats really wierd. Every charger i've tried works fine.
You're charger should be outputting 5V and anywhere from 300mA upwards. There is no max mA limit because the phone will only draw what it needs.
This might sound patronising, and I really dont mean it to, but when you say doesnt charge how do you know?
Do you mean from totally flat it won't turn the phone on and start charging it, or do you mean when the phone is on the battery indicator doesnt show a charging, and the LED doesnt go orange/green?
Or do you mean it never charges to full?
When I plug it in it's as if nothing happens. No light, no thunderbolt symbol on the battery, no screen wake-up, nothing. Nada. Now, the HTC wall charger and usb charger work fine. But if a MicroUSB charger calls itself "universal" it does not mean it will charge the Nexus. The HTC HD2 charger my wife has works fine on the Nexus though.
Hmm strange.
The charge process works like this:
- Charger plugged in causes voltage change on +ve USB line - potential charger detected.
- Phone draws minimal current (50 to 100mA) and tries to negotiate USB power
-- If that suceeds it tries to increase power to 500mA if the USB port supports it. If yes charging starts at 500mA, if not charging starts at 100mA
- If USB negotiation fails, it checks if D+/D- are bridged.
-- If D+/D- are bridged, the phone draws as much current as it can/needs
-- If D+/D- are not bridged, the phone draws a max of 500mA
There's nothing special about the chargers unless they have been wired in some special way for a specific phone. Thats why I'm very surprised these chargers dont work.
I know that if I chop a USB extention cable and cut out D+/D-, my nexus charges at 500mA. I've tried this myself for a totally different purpose. Thats no different to ground and power being wired to a 5v source.
Odd, I have three car USB adaptors and two AC USB adaptors.. All charged the phone, although only the AC charger shipped with the Nexus would do a fast charge, and none of my car chargers would. I found one that was rated 1Ah and soldered the two middle pins, now it works as a fast charger too.
The Motorola P513 car charger (OEM designed for a Droid) gives out 950mA, is super cheap (~$3+shipping), and works great for a fast charge with the Nexus One.

Thank you sir. I've been trying to find a car charger that guarantees a fast charge.
Just ordered one from Play.com for £3.99 w/ free shipping.
Maybe now I can use GPS for more than an hour...
I dunno.
My motorola charger for my old bluetooth (H780?) works fine, as well as the original google charger. I also have a car charger for my old bluetooth as well.
My suggestion, is to only buy name brand chargers?

Issue with charger

When I bought the Infuse Wednesday, I was excited to discover that the charging port is the same as my Bluetooth headset (Plantronics Voyager Pro) but while using the phone at work with the charger plugged in for the last 4 hours, I noticed my battery is around 20%. So my question is, do chargers and data cables made for other products not work with the Infuse? And if so, WHY!?
Sent from my SAMSUNG-SGH-I997 using XDA App
i can't tell you offhand exactly why but its definitely true. My wifes samsung focus (wp7) charger actually doesnt charge my phone faster than it dies unless I am doing absolutely nothing on it. My phone actually died watching a movie through the hdmi out using her charger. And of course it died with 6 minutes to go. If I find any more info as to the "why" part I will be sure to post. But I wanted to let you know the charger definitely makes a difference
ok so I found a better answer: even though they all use the same voltage. Those 5v chargers have 1 main difference. Different Amperage. Some chargers output only .5A, while others put out 1A. These differences will in turn make the difference between how fast or well it charges your device. This is info I gathered so take it with a grain of salt. If anyone has a better answer or can elaborate feel free to do so!!
Ok, this does make sense. The charger I've been using all night is 5V 180mA... Not all that powerful. Just didn't think it would leave me at 5% 8 hours into my night shift...
Thanks.

Plantronics headset chargers are rated, at MOST, 300 mA. (That's what the one that came with my 975 is rated.)
Our phones need at LEAST 500 mA. The wall charger is rated 700 mA, if you want to run navigation in a car dock it looks like you need at least 1000 mA.
Also, our chargers signal that a "dumb charger" is present by shorting D+ and D- together. I'm not sure what our phones will do with chargers that don't do this (at the moment I'm assuming the phone goes into USB charging mode instead of AC.) In the case of the car dock, what the charger does is irrelevant, as the dock signals its presence in another way and does not pass through D- and D+ from the charger. (D+ and D- go to the audio line out of the dock.)
Also, our phone (and likely many others) assume that they can get whatever current is needed from the charger, so if the charger "droops", it doesn't seem to do anything other than act weird (in most cases, drain the battery).
And another problem I found.. When I first got my Infuse, I was thrilled to see that it used the same type of cable that several other devices I have used. MicroUSB...
So I tried charging with the cable & charger from my Kindle. No go.
It will charge with the Kindle charger, just not the Kindle USB cable. Which makes the 4 extra kindle cables I have useless..
If I had time and inclination, I'd set about to figure out what the difference is between the two cables.
One of the reasons I returned my Atrix and bought an Infuse was because None of my MICRO-USB chargers worked with the Atrix. So far they have all worked with my Infuse.

One thing I learned working at multiple cell phone places: Motorola phones are PICKY when it comes to chargers. Sprint basically has an ongoing memo to every tech, moto phones are ONLY to be used with moto chargers. It makes no real sense, but it's true.
I've also noticed that my iGo charger takes a good bit less time for a full charge than what came with the phone. Also, not using the adapter and plugging the phone directly into a computer via USB, also makes charging faster. I this k the problem is the USB adapter that Samsung tossed in. Just my .02!

One thing - phones vary widely in how they determine that a "dumb charger" is connected.
Samsungs look for D- and D+ shorted to each other. A lot of generic chargers (like the $1.25 Monoprice car chargers) do this.
Apple devices look for weird resistor combinations from D- and D+ to +5 and ground. See http://www.ladyada.net/make/mintyboost/icharge.html
Mini-USB motos used weird combos of resistors to D- and D+ along with resistors between a normally unconnected pin and GND. MicroUSB defines this extra pin as "ID". Our phone uses resistors between ID and GND to determine if "other" devices are connected, such as the Jig, Car Dock, Home Dock, etc. See http://forum.xda-developers.com/showthread.php?t=820275 for more details.
The MicroUSB cable that came from our phones is pretty thin-gauge wire. I have a cable from Monoprice that should work MUCH better at high currents, and HAS worked better at high currents with the car dock and an iPad charger. (Without the car dock, it gets seen as a USB charger due to the funky iCharging resistors mentioned above. The car dock works because it doesn't pass USB D+ and D- from the charger to the phone.)
WARNING: I reference the Monoprice cheapo chargers above. They claim they are a 1A charger but they are NOT. They have a resistor that sets peak switch current of the regulator to 600 mA, and output current is going to be less than this.

Car charger for Samsung Galaxy S4

Has anyone managed to get a car charger for this phone?
I've just tried to charge the phone with my car charger modded to "AC" mode by shorting the middle pins... and the S4 gets nada...
Have they changed the charging mechanics?
Is that what's going on? I was wondering what the heck was wrong with my charger!
Yup, the car charger still charges my old HTC, even with the Samsung cable... so there's definitely something different inside the charger...
I have a 2A usb car charger with generic cable to charge my devices. It's nothing special, but it works with my S4. Hope that helps.

So I opened up my car charger and un-modded it back to original and it works like a charm now
I've got a 1A Belkin car charger and it seems to overload after a while when charging my gs4.
The green light on it blinks and my phone makes that sound when you plug in the charger.
Takes a while for it to happen but gets more frequent the longer you have it plugged in.
The charger works fine with my gf's nexus 4.

I'm using the Motorola charger (big blue circle). Got it for my Razr Maxx a year or so ago (I've gone through like 4 phones since then) and it works wonderfully. It's the best micro-USB car charger I've ever seen. Coiled cord, huge blue light (but not too bright since it's an ambient-style light), and charges quickly.

Different USB cables do pass different current even if using the same charging main. From tests I've done so far, a generic 3 ft USB 2.0 cable I randomly purchased online only allowed around 400 mA. An old Blackberry Torch 9810 cable allowed around 1200 mA. Original cable that came with the S4 allows 1900 mA. These numbers are from using the original wall charger main that came with phone.

I havent tested with my Galaxy S5, but previously I had "noname" chargers and cables, and they worked fine with my HTC One S, but didnt work with my GF's Galaxy S3.
Samsung might have made devices more "sensetive" to crap products. Try different cable (try original USB cable that came with ur phone and the charger you bought).
I tried original USB but to no avail. Perhaps this has something to do with this:

The problem is most generic car chargers are designed to work with Apple products. Apple uses a non-standard way of telling their devices essentially "hey, I'm a charger." This makes "standard" devices not recognize the charger properly. The device tends to think it's plugged into a computer and only draw around 500mAh.
You can convert a USB cable into a charging cable by shorting the data pins (on the device side), or you can buy charging only cables. I've been using these cables on my S2, and now my S5: http://amzn.com/B007F1DV76 . I used a Galaxy Charging app to verify charging rate and it indicated 1.2A on both the Samsung wall-wart and cable as well as my Scosche 2.1A car charger w/ charging only cable.

Why is this? When 4 out of 5 devices are built on Android? http://tinyurl.com/qxpnyoh
I am so irritated at not having access to quality accessories for my devices. Take for example I wanted a set of great sounding headphones that controlled my mic, my tracks, etc. But, you won't find it other than Samsung's own that come with the phone. I had a great sounding pair of Seinnheisers but could not go back and forward on tracks. I plugged it into my ancient Ipod 5th gen classic and worked beautifully! For $80 I should get full functionality for my S4 or S5! My only choice is the LG Tones. Which are awesome but if my battery dies then no music or calls for me!

Anyone wanting to know how to fast charge using the usb port on your pc/laptop?
This usually takes ages compared to charging via mains lead, the hack itself is quite simple and involves modifying the usb cable
my results are as follows (these can vary depending on what you are using your phone for, what background apps running, etc.
charging with mains lead :
4.2v
998mah
mains ac
charging with STANDARD usb lead:
422mah
3.999v
standard usb
and finally the MODIFIED usb lead hack:
4.161v
782mah
usb hack
as you can see it is a 53% increase in charging compared to standard usb charging mah, and slightly under mains ac charging mah,
as my phone is always plugged in at my work pc or home pc or laptop or whatever this works out good
TUT:
use at your own risk this is for information purposes only and I hold no responsibility to any damage that may arise
using a micro usb cable (charging cable for htc phones)
cut it using a pliers half way through the cable
using pliers again cut away the thick black wiring, the red and black small wiring, and white and green wiring
from the usb port end to the microusb connect the black and red cables together so they join
from the microusb end short out the white and green cables together
from the usb port end leave the white and green cables, do not touch these
use insulation tape/solder to clean it up and then your cable is ready
I will make a mod for car chargers also soon
see attached image showing which wires to cut and which to join up and which to leave alone, if this helped you in anyway (it should help you ) then please hit the thanks button
this mod will trick your pc/laptop/htc into thinking that it is not a pc usb cable and will allow higher currents and voltage to your phone
you can check this with current widget from market place
once this mod is done, you cannot use the same cable again for pc/usb tethering or usb disk drive, only cable can be used for charging

i use old regular usb cables, charges about 1% per minute, works great!! (not using usb3 cables)
wtf black price!! lol. mine was about $10, purchased 2 when the s5 phones came out.
I heard that cables matter the most in charging. I always use cables that came with my phone and have had no issues charging my phone so far. Have used PowerGen and Avantek. Both charge my iPhone 5 and Samsung Galaxy S4 at full speed. High quality construction and seems pretty durable.
This car charger works flawlessly at 1800mAh, i have been using it for a few month now.

I tried at least 5 different chargers and none of them charged more then 450mAh, i was really depressed about it until i found the charger linked above. Also, the fast charging USB cable *charges on 750 - 850 mAh which is just enough to not let your phone loose battery percentage while the navigation is turned on.
Try a Special Samsung Galaxy S5 Charger

I recently got a new Galaxy s5 on contract. I've heard that the galaxy s5 supports fast charging with a 2.1A charger. I bought a 2.1A car charger online, but the charger doesn't work when I connect it via a regular micro-USB cable to my phone. My brother's Galaxy s4 mini charges fine on it.
I was reading something on another post mentioning the need to modify the cable itself?
Any suggestions? I have another USB car charger for an iPad, and this charger also doesn't seem to work, whereas my old 1A car charger does work, but charges very slowly.

Hello,
I think you should go for a special Samsung Galaxy S5 Charger[/URL] car charger .I found a large variety of car chargers but you should look if it is the right watts that your S5 needs,maybe this is the reason why your brother phone charged and yours not

[Q] Weird Car Charger Problem

The Scosche car charger that I've been using with my old phone (HTC One m7) doesn't charger my Note 4, but still chargers the HTC.
This type http://www.amazon.co.uk/Scosche-Dual-USB-Car-Charger/dp/B00E1UWA4O/ the dual USB charger.
I've tried various cables (Note 4, another Samsung, Mini USB with Micro adaptor cables), they charge all devices, when connected to mains power.
Additionally, I've got a cheap 750ma output car charger, that was free with some eBay tat and that chargers the Note 4, obviously too slowly to be of any real use.
Does anyone else have the Scosche charger?
Should a non QC2 charger work, I'm guess it should?
Should I just buy a QC2 car charger?
The only thing I've not tried, is switching off the QC feature in the phone. But, I wouldn't think I should have to do that.
Thank you for any feedback.
********** Edit **********
Just to help anyone else in internet land who might be reading this.
I contacted Scosche and they recommend using a charge only cable to fix the issue with the Note 4 (and possibly S5).
I can't confirm this, I don't have a such a cable at the time of writing. But I might have shortly.
I use a Anker power IQ charger in my car and it works with the Note 4. Non qc2 chargers should work fine.

Any 1000 - 2000 mAh charger will work on our Note 4.
I've tried HTC 1000 mAh charger, even Blackberry charger & all working.
May be the Scosche pin circuitry is not compatible with Note 4, try another car charger.
I'm using Capdase 4 ports car charger (2 ports 2.1 Ah & 2 ports 1 Ah) and it charge my Note 4 quite fast even without Fast Charging capability.
Thank you all for the replies :good:
I'll try the Aukey charger.
look for a car charger that has 2.1A output rating.

Thank you for the reply.
I decided to get the Aukey QC2 model, which should arrive tomorrow.
I bought this 2.4 amp MiLi smart car charger... works very well. Even recognized the fast charging. Simultaneously charged my note 4 and my ipad air at good speed.

I use an Incipio QC2 certified 12v adapter in my car that worked fine on Kit Kat but on Lollipoop I've lost the fast charge capability, only regular charging.
