Who's been able to wirelessly charge their phone above 3 or 5 watts?
If so, Motorola's charger or another brand?
I have 3 charging pads and a stand (various brands) and built-in car charger, and none charge more than 350 or 450mA according to Ampere app. Tested at 40-70% battery.
Best charge was from 50% to 57% in 1.5 hours.
Note: Wireless chargers charge Pixels and a Samsung at higher rate as expected.

I have recently been profiling a few USB chargers to figure out which one is the best for rapidly charging my phone. A few threads have pointed to the EP851 charger being something a bit special. I was thinking about it on the drive into work..
The specs say that it charges for 60 minutes talk time in 10 minutes.
The XS has 8.5 hours talktime,
This means the charger can fully charge the phone in 8.5 * 10, 85 minutes
Plugging these values into my Charge Timer app gives an estimated power output of 1235ma, almost identical to the 1211ma of mu cheapo 1500ma charger.
Given this closeness, and the fact that the EP850 is also rated at 1500ma I am conclude that they are the same thing.
So, if you want a fast charger for your XS, and are waiting for the EP851, stop waiting and get a genuine BlackBerry Playbook 2A charger. It is about 10% faster (est 1314ma) and available now.

That's throwing some serious power at the battery, is it safe? Will it knacker the battery faster? The PlayBook charger im referring to

Is it possible that the S has the "boost" pin with its USB connector and the 51 triggers it?
This is my understanding of it. PIN 1 and 4 provide power, 2 and 3 provide data (and 5 provides USB OTG?)
If pin 2 and 3 are not bridged, the phone will charge at the maximum rate as determined safe by the usb 2.0 spec
If pin 2 and 3 are bridged the phone will charge at the maximum rate as determined safe by the phone designers.
Both scenarios are, of course, restricted by the power that the connection can supply. For example, if you plugged the phone into a 1000A charger, I would expect it to only pull about 6? amps
As for "is the Playbook charger is safe?", the Playbook has the same type of battery as the SXS, just a lot bigger. For the Playbook, this charger is considered the slow charger, and a rapid charger that pushes more amps at 12V is available.
Obviously, its your phone so use it how you want. I prefer mine in my pocket instead of tethered to a wall so I am going to use the fastest charger I can.
So USB-C is finally being incorporated into many devices these days so I would think that the days of bringing 4 different chargers on the road would be becoming a thing of the past. Unfortunately a quick test shows this might not be the case if you want to maintain the rate of charge that the OEM charger provides. My understanding of USB-C was that whenever a device ( In this case my Nexus 6P ) is plugged into a capable USB-C charger, it would charge at the highest available rate that it could take, given the capacity of the charger and capability of the device. What I found is that when my Nexus 6P was around 60% charged, I tried switching over to my new 2016 Macbook Pro 87 Watt USB-C wall charger, the charge rate slowed way down and never recovered. While it was plugged into the OEM charger I was seeing 1800 mA; then when I plugged it into the Mac charger, the rate never got higher than about 600 mA after several minutes. I then plugged back into the OEM Nexus charger and the rate again increased back to > 1800 mA. Anyone else have a different experience with chargers other than the stock one and the rates they can provide to the Nexus?
Most Apple chargers have chips for interacting with their products. Would make sense they limit unknown.

I did consider the possibility that the charger isn't built to the official USB-C power delivery spec, but I wouldn't think Apple would be the company to build a non-compliant part.
Most ac/dc usb charger (1.5A-2.5A @5V) give me 1500mA on lockscreen (Custom ROMs).
Only original charger came with 6P will show 1800mA.
(Not sure about real charging current.)
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.

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.
Got my Pixel 6 recently and noticed the charging speed has been quite slow, over 2 hours for a full charge. I realize the Pixel 6 will only reach the claimed 30W charging speed with a modern charger that supports USB-C PD and PPS, so I bought an Anker PowerPort III Pod Lite (https://www.amazon.com/Charger-Anker-Compact-Adapter-PowerPort/dp/B08F28BH7C).
However, when I connect the Anker charger to my Kill-A-Watt meter, it never shows the charger as drawing more than 10 watts from the wall outlet when charging the Pixel 6. This is despite the Pixel displaying "charging rapidly" on the screen.
Has anyone else noticed this? If you have a watt meter, would be useful to see what the actual wattage draw is when charging the Pixel 6.

make sure you turn off all the adaptive settings as it will charge based on current status and will not always charge at full speed.
What charger?
So we have the official 30W charger for £25 at Google store, which I believe most people will be going for. The pixel 6 requires PD 3.0 with PPS for full 30W fast charging. Since chargers will no longer be available in future phones and to avoid...

Check that thread out. It's got a lot of information you'll find useful.
I have a 10,000 mAh 22.5W magnetic powerbank and I noticed that the 10,000 mAh can only do a 1 full wireless charge of S23U which has a 5,000 mAh capacity. My powerbank at full charge was only able to charge my S23U from 10% until 96%. Considering that I've not used the phone extensively while being wirelessly charged and the 10,000 mAh is not true rated.
Is this really the case for wireless charging. The capacity consumed is doubled compared to Wired charging?
The power lose can be high. Wireless charging isn't ideal for a number of reasons. Excess heat production being the core issue.
The bank uses a switching voltage converter for stepping it up and/or the wireless charger does I would think. That's another chunk out of the efficiency.
