[Samsung Galaxy Note 9 Accessories] Ashton_Durkhun:
Ok, I have two similar but also distinctly different issues here...

First, I have 2 different USB-C charging cables (yes, I'm late to the party, the note9 is my first type-C device), and they likely present the (supposedly) best and (presumably) worst option...

Cable #1 is, of course, the OEM cable that came in the box from Samsung.

Cable #2 is a generic USB-C cable I picked up for literally $1 at my local Dollar store.

Both are plugged into the OEM Samsung fastcharge AC adapter (I use 2 different adapters, one from my old Note4 and one from the Note9, but I've noticed this same discrepency on both so I'm asuming hardware revisions are, at most, extremely minor between the two chargers)

Plone us usually only drained to ~50-70% (normally closer to 70%) to try and maintain the battery as long as possible and except overnight, removed as soon as I notice its at 100%

When I plug in with the $1 cable, I almost always get ~1:45 (one hour, forty-five minutes) till full charge

When I plug in the OEM cable it seems to usually be closer to 1 hour to fully charge.

I have not actually swapped them out to be 100% sure, but given the battery % is usually the same, I'm almost certain that the phone is charging faster with the OEM cable.

Does this actually make sense? Is it worth the extra $$$ to shell out for Samsung's own cables? Is it likely to damage the phone? (the last point I'm not quite as concerned with since I usually use wireless charging, but I know with some products instead of a "very slight amount each time but eventually it gets noticeable" you have "works fine 99% of the time, but the 1 time it doesn't work right it kills the device" which is what worries me on a $1000 phone...)

Second issue...

As I mentioned, I use wireless charging most of the time. I have 2 charging pads. One was literally the cheapest one on eBay that shipped from within the USA (which, to be fair, I bought years ago when I was attempting to add aftermarket wireless charging to my note4 and it was just as successful as I had expected it to be, so I didn't want to shell out top dollar for hardware that I knew was unlikely to work for me) the second charger was one I picked up from Wallyworld (I think it's "Onn" brand? whatever Walmart's "store brand" of electronics is) for $10

At first, both chargers seemed equal except for how the phone reacted to being misplaced on it (the larger Chinese one is about the same size as the phone and if not lined up right it would start-stop-start-stop-start-stop, while the Wallyworld one would not even start unless the smaller disk was centered under the phone) but now after using them for a while, the Wallyworld one seems to be charing slower than the cheap Chinese one... and its almost like the "time till full charge" doesn't go down accurately (i.e. "1:45 till full charge" then 45 minutes later "1:15 till full charge") though the battery % does go up it seems slower than it used to be...

Also, I had a weird issue where the phone was "charging wirelessly" but it never charged, several hours later it was at the same or possibly slightly lower battery% than before - on both chargers! Right now I'm chalking it up to the phone software glitching since after charging it over cable and rebooting, the next time they both charged like normal.

Again, does this sound like its a quality issue (where hilariously the cheap Chinese pad is better quality than the Wallyworld one)? Is using these 3rd party chargers possibly screwing up my phone's wireless charging circuit? (this time I'm very concerned with the risk to damage of the phone since I use wireless charging so often --- I'm even looking at buying a car windshield-mount with a built-in wireless charger)

So... thoughts?
