Hi.
Is there any notice of heat build up when wireless charging ? I got an otterbox defender case so its a little thick/ insulating.
I looked at the Samsung wireless charger and it has a builtin cooling fan....So if the mfgr wireless charger has a cooling fan, is the heat buildup a problem? A problem source?
BTW, it is a yootech 10w wireless charger and the phone says it charges faster through the wireless charger than it does through the USB cord powering the wireless charger.
THANKS !
i've been using a Pleson 'fast' wireless charger for years with my GS8+ and now with my GS21+ and while there can be times when the phone is warm to the touch i've never had a problem. I have a Quad Lock case on the device which is a pretty thick back. FWIW I also use the charger on my work-assigned GS20FE w/o issue.
I've put a Vanguard rubber case on my phone. and I'm using Samsung Wireless Charging Powerbank for wireless charging. Yes, the phone warm up while charging. It is a20 watt charger and so far, the only charger that shows "Fast Charging" while charging wirelessly. For wired charging, the fastest charger I've used so far is the 65 Watt Lenovo Laptop charger that comes with my Yoga Laptop. 0 to 50 in just 45 mins. But I got the 2nd fastest charger from a totally unexpected place. It is from IKEA. Yes, IKEA also now making fast chargers. I've bought a 23 watt USB-C + USB-A dual charger with PD 3.0 and it charges pretty fast. at least 1% per minute.
Alright thanks. I havent noticed any warming when using a wired charger...of course it isnt the the new super fast charging plug.

Wireless adds unnecessary heat and right where you least want it, inside the phone.
If you increase the gap (a case) between coils it may create more waste heat than a coupling that is closer. Air core transformers aren't very efficient.
I never use wireless but do use fast charging.

So my friend borrowed me his charger from his phone, which is a galaxy edge. It said it was charging rapidly and omg it sure did. It was super fast. Does the N5 support any kind of fast charge? Will this break my battert?
Also attaching screenshot
Thx,
Dan
how many output amps was that charger?
I tried charger that came with Galaxy S6, which has output of 5V - 2A, and 9V - 1.7A when recognizes fast charging device. It charges my N5 from 15% to 100% in about one hour, but on lockscreen, it only says "Charging", and charges it really fast, without heating the phone, which then seems to be pretty much safe.
@tampitzel If the phone doesn't get hot to touch on the back while not used when charging (warm is ok), then it probably is safe to use.
If the screen starts to flicker, or doesn't respond well to touches (eg. while typing), that means that charger is giving too much voltage and that's bad for phone. But that mostly happens with cheap non-original chargers.
Cheers!

I will check, I didn't look to be honest, I was just baffled by fast charging
Nexus 5's OEM Charger (by LG) is rated at 1 amp - whereas the Blackberry OEM travel charger (folding plugs) is rated at 1.8 amp - been using it for a year - and, it fast charge the battery typically in 1 to 2 hours (even when it's down to 25% to 40% on heavy use for the day) with its extra long micro-usb cable. http://www.amazon.com/BlackBerry-Pr...1449956341&sr=8-6&keywords=blackberry+charger
No need for custom rom or other "tweaks" - for in-car use, a 2-amp mobile charger with a high quality micro-usb cable is the "key".
Good and beefy cable makes an improvement more than you would ever imagine!
The stock charger is rated for 1.2A not 1A.
The Nexus 5 doesn't have any kind of official fast charging. However it will allow up to a 1.8A charge rate. Plug in a 2.4A charger it won't go any higher than 1.8A. Its what the TI power circuitry is rated for.
I find it a bit strange that through coincidence that the Blackberry folding blade charger is the best (I would say perfect) charger for the N5. It was cheap and plentiful as well as high quality.

Hi there,
I'ved tryed and the time for charging was the same as the "normal" wireless charger.
Well, I connect the fast wireless charger with the wall charger that came ou of box (fast charger).

I bought the same one, it charges ok.. But nothing fancy..
I would only use one if you go through cords a lot.. It doesn't charge too fast.. But if your tired and don't want to fiddle with a cord or in my case I go through cords a lot for some reason.. It's nice to just put it down and forget it..
The downside to Wireless charging is over time the heat generated can actually damage your battery.. So better stick with the fast charger...
I bought a decent Samsung Knock off charger with the Samsung logo on it.. It works just as the OEM.. Lucky me..
The specs show it charges at 1A (1000mA), which is not fast at all.
100% Brand New,High Quality!

The S6 can not fast charge wirelessly so there is no point in spending more money for a fast wireless charger. You can save your money and get a regular wireless charger.

i got a "knockoff" samsung wireless charger puck type and it doesn't charge fast because i didn't know that the s6 did not support fast charging wirelessly!
the only issue i had was every time the display went out the wireless charging would stop and wake the display then start charging.
fixed this with an app called dock station
I went for an Anker qi wireless charger and it is perfect. It's like a small hockey puck and works a treat! Under £10 as well [emoji106]?
Hi, I would like to ask you, what is your experience with that cheap S4 Qi receiver pads (for example from ebay...). Is it charging fast? How much is cover bulged? Is it dangerous for the battery?
Thank you very much for sharing your experience.
It does make the back cover bulge a bit but it's not bad.
The phone gets warm when charging wirelessly but it's not too bad at all.
Sometimes, the charging pad will detect the receiver but the phone doesn't charge. If I remove the phone from the charging pad for a few minutes and put it back, it will start to charge.
Charging wirelessly is not as fast as using a wired charger and I would say it takes about 30 to 50 percent longer.

Thank you for response. Is NFC working with that Qi pad?
I have never used nfc on my phone but I know you can get pads that do support nfc as an option.
Hi there
I have a qi receiver on the S4. My one has input: "self-adaptation" (whatever that means) and an output of 600mah. It charges at a decent speed. I use the LG G3 wireless charger and a few other wireless charging pads and they seem to charge at a decent speed. A full charge takes about 3 hours.
The cover does bulge a tiny bit, but it is barely noticeable trust me- definitely worth it.
The phone only gets a little warmer- again nothing to worry about for sure.
I am certain that it doesn't do any damage to the phone and battery. I have using wireless charging overnight everyday for the past few years on the S4 and nothing has gone wrong. I rarely use cable charging anymore
I recommend getting a qi receiver for the S4- it is worth it.
Has anyone found a Qi charging receiver so thin that it doesn't bulge at all?

Is it today something better what can more than 600 mA ?
Can you recommend something good ?
I can tell you the one from Aukey, although it uses a flat printed circuit coil, bulges a lot. Enough I didn't want to use it. It was advertised as being "ultra slim 0.2mm", but when I measured it with calipers, it's more like 0.9mm. The ferrite pad on it is most of the thickness.
No Bulge

hello guys, i recived a wireless 9w charger with my Samsung s22 ultra, and when I'm charging the phone with it, the phone heated up to around 45 celsius ...
I'm not touching the phone during the charging, also the phone heated when I'm using the 45W charger...
what I'm missing?
please guys need help
My s21u also heated up when charging wirelessly on a 8w wireless charger....I got a 15w one from a friend to test and the heating wasn't as bad....There are some days that my s22u also heats up when charging, but mostly it's cool....probably stuff/apps doing things in the back ground. I disabled the "screensaver" when charging and that helped a bit
Wireless charging by it's nature, causes a lot of heat. Charging in general does. Ambient temp will have a small effect on it's heat too.

I never use wireless charging due to the higher temps it seems to produce as a side effect. I've also heard (but not verified) that poor alignment of the phone on the wireless charger makes it charge less optimally and hence produce additional heat.
I bought a wireless charging stand with a built-in fan on Amazon a few years ago. I have it connected to the 9w charger that came with my Note9. The device does not get much warmer than normal, but of course, it does not charge as fast as it would with a USB cable.
Does it get as hot, or hot at all, when charging while the phone is off completely?
That's way too hot. For comparison, my 2022 15 Watt Wireless Duo gets up to around 103f.
Hi,
Does anyone know if such a thing exists ? It seems that the only magnetic wireless desktop chargers are for iphones and hence seem to top out at 7.5w. I have bought: https://www.amazon.co.uk/gp/product/B08S6XQFDM Which allows you to sue magnetic wireless chargers, but I'd like to get one that can utilise the 25w charging capability of my new Z Flip 4.
Any help or advice would be very much appreciated !
Thanks in advance,
Jeremy
Just to clarify, 25w is only wired charging. For wireless, max is 10w only so look for qi magnetic chargers for that speed. This one says it can do max 15w wireless https://www.amazon.com/Universal-Positioning-Placement-Operation-Compatible/dp/B096W24V1H
Thanks NguyenHuu - good to understand that clarification. Will take a look at that stand.

As far as I can see in the available specs, the wireless is up to 15W and this is something that I'm actually seeing (without the actual current measurements, just perceptibly) - the phone seems to charge quicker on my Samsung 15W QI charger than the Flip 3, which supposedly had 10W wireless charging. The brick for that charger is also 15W, so it seems legit.
I'm using a generic 15 Qi watt wireless charger from Amazon. Was dirt cheap, Did not come with wall plug. Using a generic 25 watt charger (same specs as Samsungs wired charger) my phone reports charging from about 12 -14watts. Charges up quick. Why the 25 watt? The old wall plug I was using was 10 or less and would take all night to charge if 35% or less left on battery. So if you use Qi 15 watt wireless, just make sure your wall plug is up to speed.
PS that free flip case they gave out with the strap and metal lug will not allow wireless through it. Case and strap too thick. Probably why they are dumping them for free.
Yeah, the rapid wireless charging is the thing I will miss most about the Pixel 6 Pro.
