    They say the 7pro is compatible with PD. I have a power bank that has PD and it charges at 15 watts. not at fast as dash or warp, but better than nothing... I have tried my power bank and a PD wall charger. using an amperage app, it's not charging at 15 or even close.

    anyone?

    I have tried charging on various chargers and results are, lets just say strange.
    According to spec OnePlus 7 Pro should support 5V/3A charging, but I was getting anywhere from 5V/1A on basic 5V/2A chargers to 5V/1,8A on Quckcharge 3 (5V/3A - 12V/1,5A) charger. I even had a situation with 0,5A charging because of charging cable (that was normally charging with 5V/2A a different mobile)....

    Remember to use USB PD aware (USB PD 2.0 or 3.0!) cable along with your PD charger. Using cable from Oneplus (that is USB 2.0), or some low quality 3rd party cable will not let you pass the 2A (or 7.5W) limit.

    So, you have to check:
    - version of USB Power Delivery supported by your charger (min. 2.0)
    - support for USB PD from the USB-C cable (it has to be USB 3.1 minimum!, as USB PD 2.0 is part of USB 3.1)

    Prior to USB PD 2.0 (read USB PD 1.0) there was a limit of 2A on 5V charging. So no 15W possible.

    thanks. everything is correct all the specs and cables 3.1 cables. I still can't get it to charge fast on PD. very odd.

    I charged it with a PD charger and didn't check speeds with OnePlus charger, but I notice it charge reasonable fast compared to a non compatible regular charger. I do notice the difference.

    So , I tested my GM1913 12GB/256GB Nebula Blue (bought in Italy) with the following PD Equipment.

    Aukey PA-Y12 60W PD
    Ugreen CD172 45W PD
    Anker PowerPort Speed 30 30W PD
    Anker PowerDrive Speed+ 2 12V Adapter 30W PD
    Xtrom XB203 27000 mAh Powerbank 45W PD

    And the following cables

    Aukey CB-CD6 2m USB 2.0
    Anker Powerline+ AK-A81880A1 1.8m USB 2.0
    Anker Powerline II AK-A8485011 90cm USB 3.1 Gen2

    I tested the power input with a TC64 USB C ampermeter and the Amper android app.

    The OnePlus 7 Pro's charge was between 50-60% during the test.
    I tested every combination for about two minutes each.

    Results were all the same.

    The OP7 Pro only charges with 7W 5V 1.5A Max.
    The Ampere app only shows up to 1.3A (that is the current into the battery at roughly 4V, minus the current used to run the phone at that time)

    BTW: All the cables do charge my Dell XPS 9570 perfectly at 60W with my Aukey PA-Y12.

    When it comes down to 5V3A only working with PD 3.0 and USB 3.1 cables, the Aukey 60W + 90cm cable combination should have done the trick.

    I saw a test online where someone used an Apple 60W charger + cable and was able to charge the phone at 15W.

    Can anyone confirm that?

    So maybe it´s a firmware thing?

    Currently running 3.5.8 with May update.

    Did OP remove the PD capability due some issues???

    The charger we use in the living room is a Samsung PD charger and it charges reasonable fast. Now that my wife took it with her on a trip I used a dash charger from my 3T and I can tell the dash charger Is way slower then the PD Samsung charger. Maybe not the speeds we can expect from a PD charger but with the dash charger it takes ages to charge full.

    The difference should only be 7W.

    The OP 7 Pro charges with the same rate at my QC 2 an 3 ports or normal 2.4 Amp USB ports. Only 5V 1.4A.

    Is there a setting I have missed?
    Like turning off/on intelligent battery mode or something?

    At this rate, I wouldn't be surprised to find out that OnePlus disabled USB C PD entirely so that you would be forced to buy their warp chargers if you want fast charging.

    BTW: I did ask OP's support directly regarding this issue.

    It's now day 8 of the "mostly 48 hours response time“.

    This is my first OnePlus Phone.
    Heard much about the community and that OP would listen in on the feedback.

    Currently not impressed. :)
    Seems like they changed that too, after now being the flagship provider ? ;-)

    Hi there, 7 pro user here.

    Ok my 2 c

    1. Ive stopped looking at the live amperage from the battery apps. I do have Gsam and Accubattery installed, but I disregard it.

    2. WHen I use USB-PD chargers, I do believe it is charging at circa 15W, based on feel - I've come from a Pixel 3 XL, which is PD as well, and the charging experience is similar, though the 3XL can support 18W PD.

    3. I calculate my charging rate manually, and it matches up. From Accubattery, I look at the charging record, and I can see the milliamps going in. Multiply by 3.85 (voltage), then divide by the number of minutes the charge cycle was, then multiply by 60 (to use an hour as the base unit). Divide again bu 1000, and thats your Watts charged in that hour. Now, when I do this on USB-PD, with mixed use (sometimes screen on for a bit, sometimes off for a bit, Wifi, data, all that on) I average out at about 8.5 watts. Considering 15W in, heat, cable resistance, usage, this should be ok. WHen NOT using a PD charger (5v2a), it slows to under 5W or less of net charge, meaning PD is nearly twice as fast.

    4. I also have a powerbank which has an amperage and voltage LED. when using this (with PD support), it shows 5.3V at 2.5amps = 13.75W going in. Considering this is just an average priced powerbank, I'm sure the multimeter is decent, i if not PERFECTLY accurate. PLUS the heat and cable resistance, I am pretty confident it is going in at 15W standards. WHen this occurs, it also ends up charging at about 8.5-9W (see above), consistent with PD wall charger.

    As the charge level passes 85%, you can see the amperage reduce gradually, 2.5 to 2.1, 1.6, to 0.9....

    Could you specify what model of 7 Pro you have? (and in which country you have bought it?)

    Amperage apps do only show what goes into the battery. (As I have described above)

    Using apps it is still possible to compare the amperage.
    You do not get the exact value, but if there is no big difference in current getting in to the battery , the power getting into the device in idle state isn't different too.
    (why would the phone consume more power in front of the battery with a PD charger?)

    But my TC64 is quite accurate. Tested it with my 200€ multimeter. Also it is protocol aware and shows the device choosen mode. (oddly QC 2.0 for the Pro 7).

    I think the chargers I tested the pro 7 with, also represent a good marketshare of available products at amazon p.e.

    If a Pro 7 only charges at 15W with a obscure powerbank then there is something fishy going on.

    perhaps it's only my phone?

    BTW: 12 days in I haven't heard anything from the support on this topic so far.

    So two weeks in and no response from OP if the 7Pro does officially support USB PD 15W chargeing and if I do something wrong.

    Tried the chat , but the only thing the support employee wrote was, use the originial charger and if you want a feedback on USB PD other than the AMA I should contact the press office ;)
    (OK that´s just a no on support documents for USB PD. What else shoukd he have said? ;-) )

    For me it doesn´t look good right now.
    In an other thread users are reporting that warp cherging isn´t working as advertised.
    https://forums.oneplus.com/threads/...-fast-as-claimed.1039569/page-2#post-20541605

    Maybe we have a battery issue with some devices (overheating) and the nerfed some Phones by software?

    Update!!!

    So I updated my 7 Pro to 3.5.9 today and repeated my testing.

    40% remaining charge as last time and ca. 30 Celsius battery temp.

    Aaaaaaannnd, now it charges with 15W!

    But its a bit odd.

    As before I used my Anker USB 3.1 Gen2 cable.

    When plugged my TC64 between the charger an phone, right from the start the power indicated was 10W.(Instead of the usual 7W)

    Only when I turned off the Screen , the power rating went up tp 15W.
    Enabeling the screen drops the power back to 10W.

    But I´m glad that it does work now.

    Tested this again with all the other chargers got laying around and I can confirm the power ratings.
    Only the XB203 Powrbank maxed out at 13.5W since it keeps a stable voltage of 5V instead of the slightly raised voltage on the other chargers (5,1-5,4V)

    So after all USB PD charging with 15W does work.
    But If you use the phone while charing, it still drops to 10W.

    I don´t know what made the difference. My guess is the update.
    I do not think that 5-10 degrees C would make such a big difference.
    But I will test this the next chance I get.

    And I´m back ;-)

    So, I updated to 3.5.10 instead and was shocked.

    Back to basics again
    All combinations just charged with 7,5W.
    What?!?

    So I thought, have you turned it off and on again ? ;-)

    And it was fine again. Sort of ;-)

    But now the detection circruit for the charging power seems to be a little more sensitive.

    I testetd my USB PD ensamble again and that´s what I got now.
    (before everything worked mostly with 14-15W)

    The new Anker USB 2.0 90 cm is a PowerLine II 3ft USB-C to USB-C 2.0 Cable (A8481011)

    Entries with two values had the power fluctuate between the values

    Aukey 60W
    Anker 3.1 90cm 15,30W
    Anker 2.0 90cm 15,50W
    Anker 2.0 2m 13-15W
    Aukey 2.0 2m 7-8W

    Ugreen 45W
    Anker 3.1 90cm 15,00W
    Anker 2.0 90cm 14,60W
    Anker 2.0 2m 8.00W
    Aukey 2.0 2m 7-9W

    Anker 30W
    Anker 3.1 90cm 14,57W
    Anker 2.0 90cm 11-14W
    Anker 2.0 2m 7,80W
    Aukey 2.0 2m 5-7W

    Xtorm 45W Power Bank
    Anker 3.1 90cm 11-13W
    Anker 2.0 90cm 10-12W
    Anker 2.0 2m 6-7W
    Aukey 2.0 2m 5-7W

    Xtorm 29W
    Anker 3.1 90cm 9,70W
    Anker 2.0 90cm 12-13W
    Anker 2.0 2m 9.00W
    Aukey 2.0 2m 7-8W

    Anker 12V 30W Caradapter
    Anker 3.1 90cm Turns Off
    Anker 2.0 90cm Tunrs Off
    Anker 2.0 2m 5-6W
    Aukey 2.0 2m 4,70W

    (The Car adapter seems to have developed a small issue,too.
    When the display tunrs off and the current rises from 2A to 2.8A, it shuts off.
    Replacement is on the way)

    So the quality of the voltage/current seems to be an issue now.

    As a side info. The Aukey 2m cable works fine with the Aukey 60W and my Dell XPS 15 at 57W!!!

    Somehow this mechanism or software component seems to crash sometimes.
    And then it´s 5V and 1,4A until the next reboot.

    Started at 30% 30C and ended at 40% with 35C.
