For those with charging issues [Possible Solution]

There have been quite a few people that have come into one of the IRC channels for this phone with complaints of very slow charging batteries. There have been a lot of theories regarding the slow charging, but after testing for about a week I think I may have a possible solution.
Many stated that they were using USB ports on their computers or USB hubs, while others stated that they were using the wall adapter's from their old phones. The problem with this is that, although USB 2.0 ports have 5v output (the same as a wall outlet), they only MAX out at 500mA (milliamps) or .5amps. USB 3.0 ports output at 900mA, so this is almost twice as much as 2.0...but still more than half as low as the wall charger. Also, not all wall adapters will handle the same electrical output. They range anywhere from .5amp through 2amps. The one that Samsung bundles with this phone is 2amps.
So, if you are experiencing extremely slow charging while connected via USB to your computer or hub (or even using the wall adapter for your old phone) then you may want to charge your phone via the supplied wall adapter. I realize that its probably inconvenient as most like to connect their phone to their computer while they are at it, but you can't have it both ways. And for anyone that thinks that their USB 2.0 ports are somehow magical and their phone charges more quickly than others through this method, it's not possible as 500mA MAX is the industry standard.
I tested my, and my girlfriend's, phones for the last week, and this is indeed very much the case. Laptops can put out slightly more amperage, but it is negligible.
Charging tests were performed on 2 different laptops and 2 different desktops (one through a hub and one direct to the USB port on the PC itself).
Charging from dead via USB took ~8 hours (one actually took about 12 hours during one of the laptop tests) to fully charge from dead.
Charging from dead with the supplied wall adapter on either phone took ~2-3 hours.
Charging from dead using the wall adapter from the HTC Evo 4G took each phone ~6 hours.
I realize that this will vary in some degrees from user to user, but I think for the most part it will be correct. I also had two friends run similar tests (one used the Evo 4G charger and one used the Evo 3D charger) and their results were very similar.
Most of this is probably common knowledge to many people, but for those that didn't know, I hope this helps.

Umm...the charger included is rated at 1A?

HTC 10 USB 3.1 Fast File Transfer Speeds Much Lower than 5Gbps

I've bought three USB 3.1 cables from Amazon, one cable from Startech, one cable from TechMatte, and one cable from FRiEQ. All of these cables are Benson Leung approved.
Initially I bought the Startech cable because I thought the HTC 10 would support USB 3.1 gen-2 (10Gbps), but after further reading I see that the HTC 10 (probably) only supports USB 3.1 gen-1 (5Gps).
I bought the other two USB 3.1 gen-1 cables so I could have backup cables for my home/work/travel bag etc.
Then I wanted to confirm that the phone would actually support transfers at the speeds rated by the cables. It would appear it doesn't.
I tested the HTC 10's transfer speeds by connecting it to the USB 3.1 port on my motherboard (ASUS x99-m WS) and testing file transfer speeds, but even connected to a USB 3.1 port speeds are still definitely not fully USB 3.1 gen-1 5Gps. Here are the results that I found.
With Fast File Transfer mode enabled, transfers for all three USB 3.1 cables complete at ~130-150MB/s read and ~100MB/s write speeds. These speeds are definitely not USB3.1 gen-1 (5Gbps) speeds.
I tested this by transferring a 700MB file from PC to phone internal storage (not microSD card), then transferring the same file back to PC.
The test file was transferred to and from the Samsung 950 Pro m.2 SSD drive, so the SSD drive is not the performance bottleneck.
Transfers were consistently ~3x slower with "Fast File Transfer" mode disabled.
It's possible that what HTC meant by the "USB 3.1 Gen 1, Type-C" spec was just that it had a USB Type-C cable connector form, regardless of the speed the port could achieve.
Q: Does anyone have USB 3.1 transfers confirmed working at 5Gbps (ie. ~600MB/s)? And if so, what cable/mobo are you using?

I thought you needed UBS C on both ends to get the higher speeds, no?

That's what I thought as well.

You're probably limited by the HTC 10's internal storage. Just because it's flash doesn't mean it can saturate USB 3.1 like your 950 Pro
Those transfer speeds are pretty close to what you see with sequential internal storage benchmarks, and they're among the fastest you'll see in Android phones:

High-end SD card transfer rates are somewhere in the same ballpark.

USB Type C is not the same as USB 3.1.
Type C is a connector, USB 3.1 is the protocol version supporting 10gbps speeds.
The USB 3.1 protocol works with type A 3.0/3.1, type B 3.0/3.1, micro B 3.0/3.1, as well as type C connectors.
Type C is even compatible with the USB 2.0 protocol (which is 480mbps half duplex and with more overheads).
Also, your transfer speeds are always going to be limited by the slowest component in the chain. The USB 3.x protocol itself isn't what's limiting you here. The speed of the flash memory probably is.

If you're getting more than 30MB/s then you're already getting better than USB 2 speeds (practically maxes at 30 and theoretically at 60) and must therefore be at USB 3+ speeds which can max out at 640MB/s but you're going to be getting less than that because of overhead and the speed of your flash memory.

Slow OTG adapter write speed...

Hi all,
I'm experiencing pretty slow USB OTG Write speeds while copying my nandroid backup. Currently I'm getting between 2.5-4.5MB/sec.
I'm using the much praised Anker USB C-A OTG cable with a little red SanDisk USB 2.0 micro SD adapter and a 64Gb Samsung Pro micro SD card thats rated at 95(read)/90MB(write)/s. Internally it was pretty fast in my MxPE. It definitely didn't hit the advertised speeds but was definitely faster by a factor of at least ten than the highest speeds I'm im getting now with my OTG cable. IIRC I also obtained similar speeds using the same SanDisk USB adapter on one of my desktops.
Anyone have any ideas? Should I just cut the whole sd/usb adapter out of the setup and just use a thumb drive with my OTG cable? Is there possibly something that I am doing very wrong?
-MeeGz

its not the phone or the memory card, its adapters, i had purchased https://www.amazon.com/gp/product/B01C5JJN2Y/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1 and i am getting about 12 MB/sec, i think SanDisk USB 2.0 micro SD adapter is ur culprit, I am pretty sure that is not going to say the speeds its has and it is not going to use the full speeds of the micro sd card b/c that micro sd is blazing fast, i use it for my surface, so i highly doubt it will be the phone

Thanks for the quick reply... Whats weird is that the same adapter works quite fast with my linux box and an old C2D iMac(IIRC). Perhaps my memory is failing me. I do have one or two more generic adapters kicking around. Maybe I'll give them a shot.
Then again maybe it'll just be faster to use one of my thumb drives instead.
Also, I'm wondering if I should have just purchased a micro SD to USB C adapter rather than getting an OTG cable and plugging my mSD to USB dongle into it... Oh well, I'm hoping that once my USB A Y cable arrives from China I'll be able to power my hi-gain USB WiFi and finally(maybe) do some pentesting from my phone... Anyhow I've just(almost) derailed my own post!

USB type C >> microUSB interface

My long awaited shopping has arrived, and I finally may trash those pesky microUSB cables...

Aren't you supposed to get micro USB to type c so you can use older cables?

Why on Earth should carry obsolete microUSB cables around me (in addition to USB type C cable I use with my htc 10)..?
For those rare cases I may encounter those obsolete microUSB female jacks in old devices - I had purchased the above mentioned interface.. it's small, quality and cute; it occupies no space in my backpack..
P.S. I happily donated all those microUSB cables to the Needy who still may use obsolete type of appliances..

Then why are you downgrading your operation by shifting to microUSB cables which is already proved of being a crap standard - instead of sticking to USB type C cables - as it is in my case ?????

Cos some people have spent good money on good quality cables (2m) but they can't no more so they can buy a converter.

Been looking for these, I too want to keep usb-c cables around and have the option to charge legacy devices. Where did you get it from?

How to change the Max 1.5 A (non dash charging) speed?

So I was wondering, When I dont use My dash charger the OP3 only charges with a maximum of 1.5A eventhough im using the Dash cable.
Is there a way to up this number to like 2.0A/2.4A with a custom kernel or something in that matter?

No, if you're not using both dash charger and cable you're stuck at standard 1.5A.

1.5A is limit of most cables so.. u can change it with the chance of a melting cable.

I would be quite unwise to go higher.

I have blitzwolf USB c cables that can handle up to 3 amps

Then idk..

While it can likely be done from the kernel side, I would advise against it. Some of the OnePlus 3 charging circuit has been offloaded to the Dash charging brick so we don't know how the phone/battery would react to a higher wattage standard charge. Could damage the board/battery or cause a fire.

Exactly - this is the reason OP3 charges fast only with DASH and nothing else (except VOOC which is the same thing).
It doesn't have the necessary internals to handle other fast charging solutions. And everything above 1.5A at 5V is considered fast charging.
If it could be done safely, someone would do it already; the device has been out for months and there are many custom kernels and ROMs.
We have enough burning phones already *cough*Note7*cough*, please don't try to detonate our beloved OnePlus 3 ?

USB-C can support far more (As is the case with the Nexus 5X/6P doing 3A) so the cable is not the issue.
the fast charging circuitry being offloaded to the charger itself is likely the main reason the phone can't do more than 1.5A, and if so, SW mods can't change that since it's a HW capability the OP3 lacks.
Honestly, there was no reason for this phone to have USB-C at all in terms of charging speed - this could have been done the same with microUSB.
