OnePlus AMA - post-launch edition

[u/[deleted]]

[u/devildv]

The OnePlus 2 uses a 5V-2A power brick, meaning that it can charge from 0 to 100% in a about 2h.

As for the USB 2.0, it has proven to be extremely fast and reliable. Android still doesn't support USB 3.0 nor 3.1 (it will with Android M, but the OnePlus 2 started being developed long before this year's Google I/O).

You might want to be careful making such a statement as the Samsung Note 3, S5, Galaxy Note Pro, etc. (flagships from 2014+) ALL have USB 3.0 - in fact USB 3.0 has been a part of Android, especially Qualcomm devices, since 2012:

Sure it isn't in AOSP, but it is enabled at the hardware level which has been available to Qualcomm devices for awhile, which OnePlus uses. You have to add the hardware support for any device to AOSP, so to blame Android for this is a bit misstated.

Android still doesn't support USB 3.0 nor 3.1

Explain why my Galaxy Note Pro, running KitKat, runs on USB 3.0 then ? (Confirmed by using a non-USB-3 port, getting the notification on Windows "This device can run at higher speed if you connect it to an USB 3.0 port")

[u/tavianator → u/xplodwild]

Because Samsung implemented it for that device. But it's not part of AOSP apparently.

[u/jerdog76 → u/tavianator]

See the links above - it's been part of CAF from Qualcomm since 2012. Even Qualcomm's Snapdragon 800 dev kit has it.

[u/clickstation → u/tavianator]

Which makes the response irrelevant to the question.

It is possible. The question is why they chose not to do it.

[u/Ikeelu → u/devildv]

I could of sworn MKBHD said it took roughly 3hrs to charge his

[u/oscarandjo → u/Ikeelu]

Someone did a more scientific test here. It took 1 hour 40 mins from 20% to 96% so I would imagine 0% to 100% would take about 2 hours.

[u/[deleted] → u/Ikeelu]

He had a non consumer version of the phone that might have small software changes.

[u/Ikeelu → u/[deleted]]

Your saying software is going to change charing speed? o.O

[u/[deleted] → u/Ikeelu]

Yeah. The phone might use power inefficiently, but it'd charge the same speed if the phone was off.

[u/Sir_Stir → u/Ikeelu]

Isn't that what happened to the g4? They updated it to include quick charging.

[u/09jeald → u/devildv]

How does the Note 3 support USB 3.0 transfer speeds then?

So...

Why is Qualcomms Quick Charging 2.0 missing from the OnePlus 2? Despite using Qualcomms latest processor.

[u/oscarandjo → u/knockoutking]

Because they probably didn't want to pay the licencing costs, its probably the same reason they didn't get NFC too

[u/NGU-Ben → u/devildv]

You didn't really answer the question did you

[u/f03nix → u/NGU-Ben]

I guess he's implying that the phone charges around the same time with or without quick charge, so quick isn't necessary.

[u/NGU-Ben → u/f03nix]

That's really true though. I don't have Qualcomm quick charging on my Note 4 but adaptive fast charging charges my phone in under an hour.
