Hello,
I'm thinking about buying a wireless charger, but before I do that I have one important question.
How long does it take to charge the battery (compared to normal wall charger)?
If someone has already tested wireless charging (not only with this device) could You please write a quick review here?

Hi everyone,
I have a problem with my original wall charger that came with the phone. There seems to be something wrong between the cable and the connector you are plugging into the phone. I need to have the cable in a specific position for the phone to be able to recharge.
The question is, is there any better charger than the original samsung one? I could probably get it replaced as it still is in warranty, but I don't like how slow it recharges the phone. If I am running a 3D game the phone is slowly DISCHARGING even when plugged in to a wall charger.
I noticed the charger has only 500-700 mA output. I had an older htc charger which had 1000 mA output. Would a charger like this recharge my phone faster? I have seen some posts about non-samsung chargers not being able to recharge the battery fast as there is some kind of protection built into the phone.
I would also consider buying a wireless charger if it was available for a reasonable price.
Are you all using the stock chargers?
Thanks in advance for any help.
you can read this thread: http://forum.xda-developers.com/showthread.php?t=1721677&highlight=charging
Just to make sure it is the charger's fault, does the phone charge normally if connected to a computer, from the USB port?
Thanks for the link.
Yes, phone charges and transfers data from USB without any problem, so it should be fault on the charger.
Reading through that thread, I guess there is no point in buying a more powerful charger.
as i said there, i use a nokia 1200mAh charger and the charging time is more than 2 hours, so we have to deal with it. The thing you should care of is the quality of the charger to avoid the touchscreen known problems
Imho you don`t need better (more powerfull) charger because of the hardware limitations. What you should do is to try any other microUSB charger just to see if that solves your problem. So if any of your friends of family have other samsung or nokia etc. phone, thats charging with microUSB, plug it into your phone to see if it solves your problem. You will know what to do next if it does

how do I check the quality of the charger?
Hi,
I have an HTC phone with its AC Adapter rated at 5VDC - 1A. I also have an old Motorola dumbphone adapter rated at 5VDC- 850mA. The thing is, I realized that the connectors resembled each other and when I tried to plug the Moto into my HTC I found that it was a perfect fit.
I'm wondering if anyone knows if the difference in currents can damage the battery on long-term charges, or if it will just take more time to charge? I verified and they are both 5-pins and I tried plugging into the wall for a second and my phone indicated that it was charging.
What's the opinion of more knowledgeable people here?
Thanks!
You're fine, it will just charge slower.
Hello everybody,
I have recently bought the Griffin Dual USB car charger.
I use quite often a GPS navigator when I am driving, so I wanted to buy a car charger which was powerful enough to sustain gps and 3g data plus a little extra juice to charge my phone battery. I found this charger on the internet and the specifications say it's got an output of 1A which should be more than enough for my needs. However, I was quite surprised when I realised that the battery still goes down really slowly when I use the gps app.
I've had a look online and apparently most car chargers are not recognised by your phone as a proper charger. For this reason, they provide only 500mA. You can double check this by having a look at 'settings > about device > Status > Battery status'. If it says 'Charging (USB)', it provides 500mA. Instead, if it says 'Charging (AC)', it provides more (so called fast charging). Well, my phone says Charging (AC). But it's still not enough apparently
Do you guys know any app or anything I can do to test how much the charger is actually providing?
As you can imagine, this is quite annoying.
Thanks
i'm in the same boat as you but a different dual USB Charger
It's suppose to output 2.1A + 1A or something along those lines and it does charge last generation iPad and an iPad Mini at the same time without an issue.
When I plug a Galaxy Nexus in it charges as a USB BUT when I plug the Galaxy S3 it charges as AC but a 2 hour trip only got my phone battery up to 47% which is way way too slow and that is without GPS
The AC charger that came with my phone only outputs 1A but it charges my phone in 2.5 hours from dead flat to full
My car charger is the same. 2.1A port for tablets and stuff. 1A port for everything else. I have noticed that if I plug my s3 in the 2.1A port, it charges slightly faster. However, it's not even close to my 1A wall charger.

Any idea at all?
Thanks

I don't know if this will help. have a look at the comments as well.

Hi, if you are looking for a best usb car charger for your device then i have a option for you. Please check my profile and fo to the link in my bio.. Thank you
I recall back with my old phone (Virgin Mobile LG Optimus V), the lead devs teamed up and made a flashable patch that allowed you to toggle fast charging on and off, basically telling the phone whether it should consider the power source a USB or Wall charger and it worked good. Maybe we can get some people to team up and build that for the S3?
Hi guys,
I've noticed that my galaxy s4 mini 3g comes with a 1000 mA (1A) charger and it charges at a very good speed compared to when I plug it to an ordinairy USB port (500mA only I believe) on the desktop.
It gets warm after a while while charging using the official samsung wall charger (1A)
I plugged it in my battery bank where the output is said to be 1500 mA and it charged up much faster but gets a little more warmer in the back.
I have an ipad charger here rated for 2.1A but I haven't tried it yet..
I want to find the fastest but also a safe way to charge my phone in order for the battery life to become longer before I need to buy a new one. So I want to ask you guys here in the forum what chargers do you use?
A good read that made more familiar with charging via USB:
http://www.extremetech.com/computing/159727-how-to-charge-your-smartphone-and-other-usb-devices-as-quickly-as-possible
For the battery life to remain long you should stick with lower amperages. The 1A charger should do you fine. USB ports are typically 0.5A, unless its a USB3 port which gives more amperage I think.
I've used a Mega 6.3 charger on the S4 mini before (2A).
Hey all.
So recently i just purchased S20 with an exynos cpu (since thats the only option in my country). Since this device has a wireless support, i want to try the habit of wireless charging since its more convenient while using on a desk. But thing is, is it okay that everytime there is notification i pick up the phone and put it back again after i finished dealing with it?
Check out this article, it suggests lower Depth of Discharge is better for battery life (and not charging to 100%).

I stopped using wireless charging with my S3 & S4 because the 4 different wireless pads I bought would heat the batteris so much they would swell up and need replacement after about 3 months. Luckily with those old handsets I could easily replace the batteries.
I don't wirelessly charge my S20 for that reason, I use a 1A charger daily or a 2A charger if I'm a bit impatient. I rarely use the 25W charger, only for genuine emergency use.
