I have a dumb question about charging the battery... I'm not very familiar with Li-ion battery technology.
When charging over USB, the USB port can't provide enough amperage to charge the phone quickly. I had my phone plugged in for 3 hours and only got a 20% charge. My original Galaxy (Captivate) has a wall charger that provides 0.7A. The GS3's charger provides 1.0A. I know this phone will charge slower if I use my Captivates charger.
My question... I have a Transformer Prime, and that charger is rated at 1.2A. Will charging with a beefier charger cause any issues with the battery, including but not limited to life on a charge or life period? I can only assume it will get warmer when charging, since I'm pushing more current through it.
Would you charge the battery with a beefier charger? I'm hesitant, but I'm looking for your opinion.
Thanks, and sorry for the dumb question!

I have the Transformer too and I interchangeably use the chargers and I have never had an issue on a phone regarding this issue.
However since I have never kept one phone for more than about 6 months I don't know about the long term effects.
I tried to charge my i9100 with an iPad charger once. It hit about 70% and about 120 degrees fahrenheit and then stopped charging. I would say be careful.
Hello everybody!
I've got two questions:
Since I'll be receiving my direly awaited S6 Edge 64gb tomorrow, I have two questions which I couldn't really get any good answers for.
The first one is about the speed of charging. Since the battery in the S6E can't be switched so easy, I'm a bit concerned about battery health, especially since I plan on using the phone for a long time (budget is tight). Now with my last phone (which unfortunately I had to sell in order to come up with the money for the S6E) I used one of my computers USB ports to charge the phone over night. I read somewhere, that it's better for the battery to be charged slowly and since my computer powers the front USB even when switched off, I always used it to slowly charge the phone overnight. It would be faster charging with a wall outlet, but I didnt need it to, so I figured it would be beneficial for the health of the battery.
Is that actually true? Is there maybe even some way to keep the phone from charging higher than 80%?
My second question is about wireless charging. I'd really like to get a wireless charger for my desk at work, however I will be using this ->
*cant post the link, it's the "Galaxy S6 Edge Case, Spigen [CURVED BUMPER] Neo Hybrid Series Case for Samsung Galaxy S6 Edge - Satin Silver (SGP11420)" case
case on the phone. Are there any wireless chargers, that will go "through" that case?
If so, do these chargers charge so fast, that they let the battery health deteriorate? Do they stop charging when the battery is full or is there danger for overcharging or heat building up because of the case?
Thank you guys very much in advance for answers, I'm just really looking forward to the phone and I'm eager to do everything right ^^:fingers-crossed:
You shouldn't worry really. There are rampant unjustified myths about quick-charging. If your device is designed for that feature, the processor and software work in conjunction to prevent damage to the battery. The turbo charger provides large amperage to charge quickly, then reduces at an appropriate level. I've used turbo or quick charging since the Motorola Droid Maxx 4 years ago. Today, those Maxx still function as well as the first day. I do not purchase any device that does not have turbo charging. As far as wireless charging, a decent charging plate should have no issue. I use only TYLT and I build furniture around these things. I put glass top over them and never have problems charging.
Thanks so much
Do all the wireless chargers feature "Turbo charging", or do you mean charging with a wall outlet by that?
I've read in some reviews, that in combination with the S6, the tylt charger tends to fully charge the phone, then stop charging, then after a while commences charging again, leading to the phone screen lighting up and the "phone is charging" notification sound playing, then turning off again when the battery is fully charged and so on.
Did you experience any of this?
@myh0mie I guess we are in the same state, I'm also receiving my S6 Edge on tuesday and have been having the same questions as you have about charging this thread will come in handy
@quangtran1 If you use the fast charger on your S6 Edge, are you also experiencing the screen rotation issues people are suggesting that are caused by the fast charger? I really wanna know how i should be charging my phone to avoid damage once i receive it. Thanks in advance
I myself do not have the screen rotation issue with fast charging. I do know, however, that Samsung has acknowledged this on "a very small number of S6 devices, and has the solution to resolve it". Samsung did not disclose whether this was a hardware or software issue. @myh0mie Wireless charging does not offer fast charging. Fast charging comes from the 2-amp wall block.

Oh cool then it's good to hear that it seems like it's NOT the fast charger that causing the issue and the fact that Samsung already has a solution to it
I haven't had a screen rotation issue either, on a 64GB Edge (AT&T).
As far as methods of charging, seems like the "Adaptive Fast Charging" is definitely the fastest way to charge the phone. The feature only seems to work with the packaged charger, though. I have a few 5V 2Amp chargers that don't charge my phone as fast as the packaged Samsung charger. It's extremely effective when you're very low on battery life, below 25%.
If you look at the Samsung charger label, it says it outputs at 9V 1.67Amp OR 5V 2Amp. The 5V 2A is standard on many chargers. The 9V 1.67A must be the Adaptive Fast Charging.
For wireless charging, I purchased a few PowerBot Qi chargers (very good price and reviews on Amazon) and supplied them with 5V 2A power to keep myself topped off at work and overnight. To me, they seem to charge the phone at about the same speed as a generic 5V 1A power source.
My last phone was a HTC One M7 and I kept a close eye on the temperature with an app called Cool Tool. I still run the M7 in the same operating environment as my S6 and have noticed that the S6 runs 10-15 degrees (Fahrenheit) cooler than the M7 in both charging and non-charging states. Hope that helps.
I have the S6 edge with the TYLT desk charger and the TYLT car charger dock. Neither of them charge the phone quickly at all. I am not a fan of either really, but I use the desk charger on my desk at work and it is fine to keep the phone topped up throughout the work day (I forget it's even there). The car one, however, is going back. It charges hellishly slow, especially if you run any tasks like music streaming or GPS. Not a fan.
Can anyone confirm this? When i use adaptive fast charger to charge my phone, the charger it self is cool but the head of the micro USB is very very hot. Is it normal or i need to replace the cable?
It's okay. Mine gets hot, too. Keep in mind that the current and voltage during fast charge are higher: 9V 1.67A (15.3W) , a regular charger supplies 5V 1A (5W).
Same here. The USB Port (Charger Side) heats up a lot. Started yesterday apparently. Until now it was fine!
Smells bad (The expensive smoke smell) on the USB port of the charger. Doesn't seem normal to me.
I was searching over internet, mine gets extremely too.
when charge, my charger is hot and sharp noise
Same here.
My charger "head" the part that goes into phones gets really hot, but it's normal I guess. A couple buddies have reportedone same thing.
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 G6 can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!
I have used the charger that came with it (since it was the only USB-C cable I had at the time) and it charged amazingly fast. I bought a Wireless charger as well which is also amazingly fast. It's my first wireless charging experience and I was told it trickle charges so it would be much slower than charging from the cable, but I barely notice a difference in speed at all. I keep checking the phone what seems like every couple of minutes if not seconds and the % has increased by a lot more than I would have imagined. I thought wireless charging to be pointless and a who-cares ordeal, but not that I have experienced it... I don't think I will go back to a device without it (not for a phone at least). I'm not sure if any health issues can be there from radiation, but I'm almost dead anyway (well... I have about 50 years to go I guess) so I don't really care, lol.
For those wondering, I went with the CHOETECH Qi Model T513 wireless charger. Input: DC5V/2A (Max) Output: 7.5W which I purchased from Amazon for only $19.95. That was 50% off at the time I purchased it, but that was only a few days ago so you might want to check on it.
Really? I feel my g6 charges way slower then my S7 edge. I still have it but I'm gonna test this tomorrow.

Went and picked up this bad boy today. LS variant. Out of the box, had 41%. Using my car charger Qualcomm Quick Charge 2.0(yes 2.0) and the included USB C, it charged to 70% in the 20 minute drive back to my house. For using the old QC tech, still charged amazingly fast. I have a QC3.0 39W wall charger that got delivered this afternoon. Will wait til this baby dies and charge her up with that and will report back.
Ive noticed when using a QC 3.0 charger and cable doesnt seem like the g6 is actually charging faster. Its suppose to support QC but its not.
I'm finding this charges a lot slower than my S7 Edge as well. Using the provided cable and charger it takes about 2.5 hours to go from 5% to full which is generally fine, but there isn't a burst and then trickle. I appreciated being able to plug my phone in for a short time when it was low and top it up enough to go out and not worry about it dying. Can't really do that with this one.
I had a power brick laying around and says qualcomm 2.0 and it charge`s really fast, like 1% of battery every min. , but yes with the stock charger brick takes forever to charge.
Using a Xiaomi USB C charger (45W) which supports both UPD 2.0 and QC 3.0, my phone charged very fast.
Mine charges super fast with the supplied charger. I plugged in with 11% yesterday and hit 50% in like 25 minutes.
quick charging is convenient and all, but is there a way to revert to normal charging? I don't want to accelerate my cycles. Thanks.

Use a non-QC charger.
thanks. I'll do that, I have to get extra cables anyway. Although I was wondering if there was a way to hack it phone-wise.

the charger that comes with the device doesn't support QC3, it's a QC2 charger.
so, getting a QC3 charger would defiantly decrease the charging time :good:

I'm pretty sure the supplies charger is QC3.

Silly question - is there an easy way to tell if a charger is QC2 or QC3?

Look to the charger specification, if it supports only 5v and 9v then is QC2. QC3 scales on various voltage between 5 and 12 volts.
And yes, the provided charger is QC2, probably the same Found with the G5.
Yeah I take back what I said. The supplied charger does appear to "only" be QC 3. It still seems faster then QC2 though. Maybe it's just in my head. It works for my needs though, I can get almost 50% in like 20.
Charge in airplane mode when you can. When you have no worries of anyone calling or texting. With wifi off as well you'll see a decent jump in fast charging.
purchased by phone a couple of days back and it charged from 5% to 100% in approx 1.40 mins with the stock QC 2.0. I'm damn impressed....
Let me Ask y'all something. Coming from a LG G4 and just Charging My Batteries by a OEM Battery Charger I got 2HRs More of SOT. When I charge via the USB Quick Charger I got the same 3HRs as usual. So I got 5 while charging Slower then the SO-Called Quick Charging. To my understanding Batteries are meant to Slow-Charge rather then Fast
Hey, is it safe to use original 45W Samsung charger daily? Got it for nice price ($25) from friend's shop.
I read somewhere it's not recommend to use 45W. Also I read S20+ supports 25W only.
Thank you for answers.
It is safe to use the charger but I am not sure if it will be able to charge it at 25W also.
So if I will use 45W, charging will be the same as with original charger?
Tried it, remaining time to fully charged is showing the same with both chargers.

I have the 45w charger. Charging speed depends on the phone temperature. The phone slows down the charging when phone temperature gets high. It's marginally faster than the one that came with the phone. But it's super fast charging for the first 30 minutes or so compared to our of the box.
So i use the 45w charger at office when I need to charge the phone fast and seldom fully charge it as I would unplug it and go somewhere else.
At home I just plug in the charger that came with the phone for overnight charging. Perhaps not the best to leave it charging overnight but I need a full battery next day.
Even if the charger provides 45w, the phone will only pull what is needed from the charger itself. So if the phone limits itself to 25w, then thats all it will use from the charge available.
Equally, if the charge provided is lower than the maximum the phone can use (i.e. 25w phone but 15w charger), then it will use the maximum from the charge available.
Chargers these days offer a multitude of different voltages and amp ratings, but they are smart and will only send what is requested by the device that is plugged in so there's no chance of accidental over-voltage.
I too have the 45W samsung travel charger and did a comparison on power draw compared to the 25W charger that is included with the phone. I used both the USB C cable that came with the phone (Black) and the thicker cable that came with the 45W charger (White), while measuring the power draw using a power consumption meter that was plugged into the wall between the charger and the outlet. My phone was at 40% charge when I tested. The results are shocking.
Included 25W charger
Phone's Black cable - 27.9 W
Charger's White cable - 27.2 W
Samsung 45W travel charger
Phone's Black cable - 29.7 W
Charger's White cable - 31.3 W
The similar power draw explains the charging speed difference of 10 minutes which many reviewers on youtube have observed. Taking another step, I have read that the S20 Ultra requires the charger to support PPS to achieve (10V, 4.5A) in order to charge at 45W. So why does the 45W travel charger only support (15V, 3A), (20V, 2.25A), (3.3-11V, 4.05A), (3.3-16V, 2.8A) and (3.3-21V, 2.1A)? Even the best case scenario would be to use the (3.3-11V, 4.05A) PPS profile and set it to (10V, 4.05A) to give only 40.5W. I smell a rat.
Interesting. I have also measured power draw but my results are bit diferent.
45W charger was getting up to 41W for 4 mins.
On overall charging speed 0-100% the diference is 10mins, but after charging 20mins I'm getting 54% on 45W and 37% on stock.
17% in 20mins it's a lot of difference.
45W is slowing down up to 1A after that to cool down the phone. 25w have similar behaviour.
Baseus 65W PPS chargers triggers SFC 2.0 but it takes more than 2h to charge fully. Amperage is oscilating as hell.
my Huawei 65w laptop Charger charges my S20U much quicker than the 25w charger i find...

I have been continuously testing and found that if your phone has less than 30% battery and the battery temperature is under 33 ºC, it will charge at 40W. After that, it drops to 30W for the remainder of the charge and then drop again to 20W when the battery is above 80%.
Next step is to find a good battery data logging app which logs battery percentage, battery temperature, charging current and time. Surprising to find that not many apps can do this. Even the Battery Charging Monitor app doesn't log all that data.
