Glad Tidings!
It is my understanding that, with standard 5 volt chargers, in general a high voltage charger is preferable because the device takes only what it needs. I am curious what the thoughts are concerning the Qualcomm 2. 0 technology, and if the consensus is that the same holds true for those devices.
The reason for my question, is that I purchased a Qualcomm 2.0 charger that puts out 25 percent more power across the board than the stock droid turbo charger. Should I be worried, or just let her rip on my new Droid turbo?
The stock charger has the 2.0 technology as well. Which did you purchase that puts out 25% more?
From Motorola's website:
Our fastest charger ever — incorporates Qualcomm® Quick Charge™ 2.0*

No worries, the phone is measuring battery temperature and other variables continuously while on charge and it will adjust the charge accordingly, when done it will stop charging altogether. This is also why if the battery is completely dead it wont quick charge until it picks up a little battery, quick charge has to be enabled by the phone and the phone cant enable it when it is dead. Just an fyi...
Thanks krabman!
Great explanation, leaves me even more impressed with this phone! I have been just a bit concerned about heat, as the temperature gets up to 111 or so. Good to know I needn't be too worried.
C, the charger I bought is a Tenergy. It puts out 18 watts at the two Qualcomm 2.0 configurations, and even cranks out 10 watts at the standard 5 volts. It's actually a pretty cool charger, the indicator light glows blue for standard charge, but changes to green when it is charging a Q 2 device.
Merry Christmas, Happy Holidays everyone!
I have gotten the phone yesterday to 135F and I could be baking cookies on it ahahaha. Reason why it was so hot was because I was downloading movies on my phone and charging with turbo charger. But at 135F I got a warning saying temperature above normal. Once I disconnected the phone it went to 132 F and got new notification saying temp back to normal. So my guess is that the battery can take some serious heat.
My phone gets hotter than usual when I'm using a Qi wireless charger.
woke up today and my phone was at 48°C. It's hot as hell here, tho. 31°C right now...

Check the post above yours
So basically to get the fastest charge, I should throw my phone in the freezer while charging?

Yeah, man! I wasnt expecting that high temps. My phone was charging, but during the night I turn everything off, so it doesn't wake me up.
I really don't wanna try doing high usage tasks while charging...
I've had a couple phones with a version of the quick charge feature and they all got hot while charging, the Find 7 can get uncomfortable to hold if you are charging while surfing as an example. With any of them taking charge at idle they got warm but I wouldn't say hot. I am curious about having a high temp on a wireless charger though, I wouldn't have expected it. The N5 was my last phone capable of wireless charge and I don't recall it getting anything more than slightly warm. I'm not sure if it makes any difference but I had the Qi charger google sold, it was fairly slow charging.
same here
I received this unit for the note 7 but with the unfortunate event, I had to test it with S7 Edge which, on paper, works exactly as same as S7 and note 7.
This thing charges very quick, I'll say faster than ordinary power banks or cheap 5v 1A adapters.
I'd like to do a comparison on charging speed (see images) on Galaxy S7 edge with LG G4 for this charging pad.
I was going to add note 7 on this review but with all this recall issues, I'd update as I go. IF I ever get my hands on it again
there are two LED indicators, green means fast wireless charge, and blue means ordinary wireless charge.
on S7 Edge, took about 25 - 30 min to go from 25% to 46% with cool temp (30 - 32C) , that's pretty good for wireless.
on LG G4, took about 25 - 30 min to go from 21% to 33% with warm temp (40C)
on S7 Edge, it outputs up to 1.5A with 4V on my quick charge 2.0 adapter.
on LG G4, it outputs just shy of 0.8A with 4V on my quick charge 2.0 adapter.
by comparing these two setups, I concluded that it charges close to twice as fast as regular charger. I am very impressed.
I also have CHOETECH's regular wireless charging puck. I have to say, the regular puck I have is easier to charge, meaning it tolerates slightly off center but still charges as well as offer greater charging distance off from the pad, but this fast charger doesn't tolerate much, I'd have to remember to position in center for it to charge my devices. but you'll get used to it as the LED indicator will flash if you didn't set your phone straight, solid light means good. also it works well with slim cases as you can see it on my attached images.
I would strongly recommend this to anyone who is thinking about getting fast wireless charging.

and this is the regular wireless charging puck I was talking about. blue LED works with ambient light, meaning it won't burn your eyes at night. it dims automatically.

got a chotech wireless charger myself from ebay. cost £10.00. worth every penny...very similar to yours. crackin stuff.

I've got the black Samsung Wireless Charging Stand which comes with Samsung's fast travel charger. It's very fast and I use it with my SM-G935FD (Dual SIM S7 Edge Exynos). Comparing the times from the fast charger, the wireless stand is usually just 10-20 min slower. That's according to the estimate Samsung shows in the notification tray once you plug it in. Haven't measured the timings myself yet.
The temp goes around 35C to 38C during fast charging but if I leave it on the charger even after full charging, the charging stand stops charging but the battery temp stays at 32C. Off the charger, it will fall to 26C which was a little disappointing since I would have loved to leave the phone on the stand all day since it looks cool especially with the Always On display clock. I measured the battery temps with CPU-Z.
Charging speed is definitely faster than a normal charger plugged in.
Ebay must be 7.5watts and not 10watts

is it safe for our phone?
Has anyone heard of a wireless Quick Charge 2.0/3.0 external battery? If yes, please post where this can be bought.
Here's a wired one:
https://www.amazon.com/Anker-PowerCore-Qualcomm-Backwards-Compatible/dp/B01CZV9FUW
You could fashion a wireless one by attaching a QC wireless charging pad, but it would be incredibly energy inefficient due to increased heat loss. Why bother?
I've got one and I highly advise against it.
1) It gets REALLY hot, it can't be good for the battery.
2) It's considerably slower than cable.
3) You won't get as much high quality batteries as there's less competitors making them, the best batteries are not wireless.
I hope this helps.
http://www.banggood.com/Qualcomm-Ce...t-Power-Bank-With-Power3S-Tech-p-1062286.html is one I just bought - only got it yesterday but very nice build quality and my Note 5 registers it as a fast charger.
I was hoping there would be one selling in the market, but judging from your replies, i guess not.
There are actually those selling QI-enabled external batteries, that got me into thinking that QI-enabled Fast Charging should be possible.
RAVPower Wireless Charging Pad with 5,000mAh External Battery Pack for Samsung Galaxy S7, S6, Nexus 6 5 4 7
Even samsung is selling a QI enabled External Battery Pack for Note5.
Samsung External Battery Pack for Note5
I guess i will just make one. Thank you for informing me about the heat issue, perhaps a silicon or ceramic plate will be sufficient to insulate the battery from the heat.
Still, if you encounter any wireless QI Quick Charge external battery packs, please do post.
I don't know about wireless. Seems like a good idea but I would think it would be very inefficient.
I have the Anker PowerCore+ 10050 and I love it. It works so great that two of my family members got the same one. Highly recommended. I have to admit it does get hot sometimes but not to where I've ever thought it was "too hot".
Hello,
My Galaxy Watch 3 heats up during charge, either on Samsung dual phone-watch charger or on charger which came with the watch. Is it the common experience?
Thanks!
no.
is this your first smartwatch or first galaxy watch? do you have LTE or BT only?
what was the charge % when you placed it on the charger?
wireless charging is very inefficient. its imperative that you place the watch directly on the coils or else you will experience some warmth. if you have an aggressive watch face that uses a lot of power, this may also contribute.
ive an LTE varian and always purchase the LTE variants of this brand and i have not experienced this. now if the battery is flat in the watc and ts charged to full, it will get warm - that in my opinion is normal.
I have the T-Mobile USA version. Several days back I was charging and also streaming audio via the web browser via LTE. Watch got rather warm and warn me it was overheating then powered off. I let it cool down no damage I guess running all of that code it's a little more than that little watch can handle.

Thanks,
This is BT version. Stock watch face with only battery level complication. I charge the watch on 20-30% discharge. Always precisely aligning with coil.
The watch does not became really hot - no overheat warning etc.
My only concern is that I've red that overheat kills battery.
I don't know if it also for Galaxy 3 since due to MIL standard it's made to stand up to 50 C temperature - the watch does not became that hot. I think it gets may be up to 40 degrees.
I'm looking for recommendations for a charging station (or multi port charger) that will activate super fast charging on my S21 Ultra. I'm looking for at least 3 or 4 ports. I see a lot of stuff that say up to 100 watt charging but none really say if they activate super fast charging on samsung phones. If it can 45 watt super fast charge my tab s7 plus also would be a big bonus.

25 watts is as much as I go with for this generation of Li cells.
45 watts doesn't charge that much faster and creates even more heat, stressing the battery especially on the deeper charge cycles.
Just replaced a swollen Li on my Note 10+.
I'm lucky it didn't damage the display... that's what you're risking. The bag pack Li's aren't very robust... I torn one apart recently.
If you go with none OEM cables and chargers they may or may not work. Troubleshooting fast charging issues is a real pain as it is.
I just got done learning that
Adding more potential variables will only add to the trouble when troubleshooting.

The original one that came with my 10+ after a year and a half is still functional.
It's gotten heavy use.
It outlived the battery
The 25 w brick/cable can be had for $20 now... I know because I pick up a pair when troubleshooting fast charging... now I have two. Yes, well... I'm more conservative now with charging limiting the time/% as well temperature and rarely going under 40% or over 80%.
Most times I use a damp microfiber cloth to cool the charge cycle as even a 20% midrange charge can top out at over 100°F. New batteries soak up more current faster and the waste heat comes with that when fast charging.
Li charging itself is a weak endothermic reaction but the resistive heat produced greatly outweighs that lesser factor.
My thoughts on the charging situation with the S21 Ultra
In the newer S21 series (as with the Note 20 Ultra), 45W super fast charging 2.0 support has been dropped (I suspect it has something to do with the findings stemming out of the Note 7 battery fiasco investigation). From the reports I've read, they seem to have invested a lot of money and resources in studying battery safety after that embarassment, and have a new lab dedicated to studying battery and charging safety.
Max supported input wattage on the S21 series is 25W (so called superfast charging) and then there is the regular 15W "fast" charging. There's also 9W and 15W wireless charging (latter only available vis proprietary Samsung wireless charger)
There isn't a very big difference in the charging times between the OEM 15W and 25W Samsung adapters - there's a differnce yes, but its not a huge margin - definitely not what a 66% higher wattage charger should provide (25W over 15W).
Heating during cable charging is present on the S21U both with the 15W and the 25W charger, way more than what I have experienced with Warp charge on my OnePlus phone. This is despite the much higher wattage used by OnePlus, thanks to the VOOC implementation from Oppo, with lower voltages and higher amperages, and letting the charging brick do most of the thermal dissipation rather than the phone. Samsung on the other hand uses USB PD 3.0 + PPS standards.
If you're using a wireless charger without a built in fan, you get an even hotter phone than with the 25W cable charging, despite a lesser charge throughput. It's objectively worse for battery longevity because the battery is kept at the higher temperatures much longer due to the slower charging speed. Heat and Li batteries don't mix well.
From my limited experience with various charging standards and different phone brands, my conclusions about the S21 ultra are as follows:
1. Regular cable charging works just fine on the S21U. I use regular QC 2.0 chargers lying around at home and they work fine for charging up the phone without wearing out the battery. I plug in the phone whenever i am not using the phone, like for 15 to 20 mins at a time and most battery experts say that multiple small top up charges are better than a high stress pedal-to-the-metal full charge.
2. 15W is the fast charger of choice that I would charge the S21 Ultra with, if I needed a quicker boost on a nearly flat battery. 25W performance doesn't justify the extra cost of the brick. If you already have a 25W charger, then use that - what I'm saying is, there's no point buying one thinking it will charge 66% faster than the 15W charger.
3. I avoid Wireless charging on the S21U with third party Qi chargers (these only charge at 10W or lower). The phone really heats up depending on the charger - and then safety protocols slow down the charging speed even further on an already inefficient power delivery system. I would either use the OEM Samsung fast wireless charger (15W) with built in cooling, or none at all. This ensures minimum charge time to full and active fan cooling - least thermal stress is what I'd look for here.
4. My phone's battery charge level usually ranges from 20% to 90% - i try not to let it run down to flat or charge up all the way to 100%. If it does so occasionally, it's fine - the phone can handle it. I just try not to let it happen all the time. Have you noticed how fast the battery falls from 100 to 99? and then to 95... but it takes way longer for it to drop after that? 100% charge is a very unstable state for the battery 85-90% is the sweet spot. And around 50% is the most stable state. This is why Li Ion batteries are shipped at near 50% charge by most smartphone manufacturers to provide longest shelf life (the company has no way of knowing how long the phone is going to sit on the shelves before being sold)
5. I don't charge my phone overnight. I know that good chargers stop supplying power once battery reports 100% charge, but it starts charging up again when battery drops to 99%, charges it back to 100 in a few mins, then it cuts out and battery drops again and the cycle continues many times during the night till you take your phone off the charger. We know 0% and 100% battery level are the highest stress states for a battery - yet we leave the charger connected overnight, maintaining the battery at 100% for 6 to 8 hours at high electrochemical stress level.
All this is inconsequential if you change phones every year. You can do anything with your phone if you aren't planning to keep it for very long. I personally use my phones for 2-3 years and like to keep the battery is as good shape as possible. The above charging discipline has helped me maintain good battery health on all my devices for an average of 2.5 years each.
Some readers may not agree with my assessment and recommendations. Please feel free to disregard them and follow whatever has been working for you over the years. My use case and lifestyle may be very different from yours and consequently your charging habits will vary. That is fine.
This is not a directive from me to anyone, nor am i a battery expert. These are just my observations and advice for people that may be looking for it. If you've already figured out your best cahrging protocol, I'm happy it works for you.

On my Note 10+ it fast charges at about 2%@minute until about 80%. Much faster than a 15 watt brick can at 1%@minute in snail mode.
On the N10+ it has to have a 25 watt brick for fast charging to engage. I believe this is true with all Samsung models that support fast charging.
For brief midrange charging which Li's prefer, it's perfect. A damp microfiber cloth and/or a fan to keep it cool.
The temperature rise is due to resistance mostly in the battery it's self rather than the method of charge. More VA per minute, more heat*.
Samsung ditch the 45 watt brick because it was only a small increase in speed mostly in the 5-20% charge range I believe it was. This had nothing to do with the N7 fireballs. However a full charge with a 45 watt brick is the most battery stressful charging routine.
Honestly I'm not worried about longevity of the battery on my phone. I usually only keep a phone from 6 to 8 months. I just want something that works.

I'm not either anymore. I now know that changing out my N10+ battery is well within my skillset comfort zone. I could switch to slow charge midrange partial charges vs fast midrange partial if I wanted maximum life.
I just don't want to get too stupid about it*.
A swollen battery is an immediate threat.
That should be a consideration as an "event" can be painful and de$tructive.
"My pants, My Pants are on fire!" Bah-ha-ha-ha
I've had things blow up on me and onto me... better think and move real fast, and be lucky.
It's always better not to test your limits as eventually you'll discover them.
*sleeping with a charging Li is a bad idea. In the very rare instance were an event to occur it could easily be the last one for you. Anyone who's been sleeping when a fire broke out knows this.
Some of us already know people who died sleeping during a fire as well. As you get older you will too

15 watts, got you. I never use wireless or power charge; too inefficient.
Still considering removing that antenna. A substitute sheet of graphene might improve heat transfer performance and characteristics.
