Question Brand new Nord 2 charging very slow. - OnePlus Nord 2 5G

Hello, I just got this phone a couple of days ago, basically i migrated from a OnePlus 6 to this Nord 2 and I'm liking it very much so far for the price all things considered, tedious bugs and all.
The gist of it, is it normal for it to charge this slow? I'm using my old 20w dash charge adapter, because imported it from the UK, it came with said adapter and my country does not support that kind of wall plug outlet and I refuse to use an adapter/extender because it won't stick to the wall it's just too heavy.
Did some reading, and I disabled optimized night charging/high performance mode. I figured using an old adapter would be slower than the new one, but are those readings normal?
Also i noticed the Warp Charge animation appears on lock screen but just the blue bubble then it disappears, no Warp Charge logo.
I plan on getting both wall and car warp chargers, in the meantime I'll be using my regular 20w dash chargers.
Thanks in advance.

I can at least confirm that the original second (and last?) generation carplug (12V charger) is also veeeeeeeeeeery slow. It takes at least 2,5 hours from 0 to 100. The 230V plug charges 0-100 in exactly 29 minutes

You need S-VOC/DASH/WARP charger.

I'm getting 500mA (2.5W USB base current) when asleep, and 1A (5W) when awake. It's definitely buggy, should always pull 1A even when the screen is off. The phone doesn't seem to have PD, so there's no way to get 15/18W on ordinary PD charger.

Remember that accubattery only reads from a single cell of your battery;
The OPN2 has 2 cells and charges both simultaneously, so it's likely accubattery is only reporting half speed, to one cell, and isn't detecting charge to the other cell, which is half of the battery in this case.
For example, accubattery will likely report your battery health/capacity is only 50% (more often lower), because each cell is 2250 mah, and the total advertised design capacity of the OPN2 is 4500 mah, but is really 2250 mah per cell, and has 2 cells.
This is part of oneplus's warp charge technology, which is really just a rebrand of their sister company's, but it's essentially a 32.5w charge to both cells, which is much easier than providing 65w to a single cell.
Also, do note warp charge only works with the official red cable and the official oneplus charger provided in the box, as the charging circuit in the cable and charger will limit your speed with third party charger/cables as they have not been verified to handle these charging speeds.
Funnily enough even if you have an OPPO cable and charger, which utilizes the same technology, warp charge on oneplus phones still won't activate and it'll charge at a much slower 20w (10w per cell)

VOOC 2.0 (20W 5V/4A) vs S-VOOC 2.0 (65W 10V/6.5A). The OS reported current is always current over both cells, whether it be parallel or in series depends on VOOC version.

9v battery based charger for the TyTn

hi guys.
im trying to build a charger for the tytn that would charge from a 9v battery rather than using the wall charger so that i can use the tytn when im trekking (which i do a lot).
ive used a 7805 linear regulator to pull down the output voltage of the 9v battery to 5v @ 1 amp as specified on the wall charger. ive also hacked the mini usb cable to short pins 4 and 5 so that the tytn draws power from the battery pack.
the problem i face is this:
the tytn does seem to draw power from the battery pack and charges from 90% to 100% in a matter of minutes. but once the battery meter goes below 90%, no matter how long i connect the tytn to the charger it refuses to charge. but the indicator light stays orange (or amber) and the battery status says its charging, but still the tytn continues to lose power over time. any ideas why this is happening? or what i am doing wrong? any help would be greatly appreciated... thanks in advance!
My guess is that you are trying to use a PP3 type small rectangular 9v battery. If so you will find that the battery can't supply enough current to charge the unit. If you look in the Magician forum here this seems a much better alternative, as a decent set of NiMh AA batteries can supply 2700mAh, which should be more than enough to charge your TyTn.
thanks man! will try it out tomoro.. did that before i hacked the cable.. havent tried since... will do it and post what happens.! cheers
nope! it still doesnt work
i tried connecting 4 1.2v NiMH batteries directly to the hacked usb cable and the orange led comes on and the battery status says charging... but still it loses charge.
i also tired using 4 AA alkaline batteries with a diode to pull down the o/p voltage and the results are same as the above...
the AA battery pack output was 5.2v @ ~1.2A which is pretty much the same as the wall charger
I got this: http://www.boxwave.com/products/batteryadapter/index.htm

but it barely charges TyTN, very slowly. Is TyTN that power hungry? I don't know. Been using 4x2700mAh.
damn!
well there must be something im doing wrong! i cant figure out what though... it cant be the input voltages or the current.. and the cable i use is the one with pins 4 and 5 shorted.. why the hell doesnt it work???
can anyone help me? point me in the right direction????
My TyTN did charge some but faster in the beginning and soon almost stopped charging, maybe the voltage drops as batteries drain and TyTN doesn't like that or maybe 4x2700mAh is still way too small for TyTN.
alright that might have been the reason, so this is my workaround.
i connected 2 9V batteries in parallel with the set 4 1.2V NiMHs.. after passing this through a diode i get an output voltage of around 5.3V @ 1.3A.
the connection in parallel helps maintain the voltage of the battery pack at a level more than that of the tytn and prolong the time for a voltage drain.. so in theory the tytn should atleast jump from say 60% to 70% and the diode should prevent the tytn from charging the battery pack.
inspite of all this, the result remains unchanged! tytn led glows orange, battery status is charging and the phone loses charge!
what the hell is happening here?!?!?!

When I go away and don't have ready access to power (camping etc.) I use one of these Clicky.
I have found they work fine. Only thing I would say is that the 3 to 5 charge cycles is optimistic, I find I get about 2 charges out of a set of 4 batteries.
as far as I remember the 7805 is a 1A max voltage regulator, I would suggest trying the 78S05 - same pinout, 2A version, it seems to be the delivered current which affects charge rates on the phones.
or you can put in paralel on a heatsink few 7805's. Don't count on 1A for 7805, is gonna die quick, be more conservative )

Battery drain while charging & navigating in car

I have a 2 USB port car charger made by capdase in my car.
It outputs 1A, so its around 0.5A each port.
Yesterday I ran out of battery and had only 15%, so while driving I plugged it to the charger.
While talking the phone, it still went down to 14% and it took a long time till it managed to gain some percents. During that time only a voice call was made.
And I was only making a voice call....
So during 1 hour drive, I only gained about 10%.
Now Im about to go for a 1 week trip where I'll be massively using my phone as a GPS and I wonder if it'll even make it through the day.
What would you suggest me to do?
Maybe should I use a different kind of charger? would it make any difference..?
I hope to hear your opinion,
Thanks.
I've heard others having similar problem while using power hungry applications while charging, the power supplied by charger isn't enough to run the device so battery has to pitch in as well.
I use a car charger that claims 1 amp output (single port) and it will charge (albeit slower) while I play graphic heavy games.

Same here, i use a belkin 1 Amp charger in my car connected to my Brodit holder.
While using Navigon and before Sygic nav. both where charging.
Does it really supply 1A to the device?
because when I used my capdase with a battery monitor widget, it would receive a current of max 0.5A, and usually less than that...(I guess due to battery drain)
is this the one?

The stock AC charger output is 1 amp, so it must take more than 0.5 amp.
my charger is a traveler charger, it gives 0.7A :s
I hope that belkin is good, i'll give it a try..its cheap so I dont mind testing
Same here
Using navigation on my trip to greece, and putting a phone on USB charger from car power supply, battery was draining, not charging. so, I used navigation, than when driving 50 km on highway i switched off navigation in order to get some energy, and then again turn it on before I need it (I was watching at my km scale, ).
The problem is nearly always not what the charger can supply, but whether the charger complies with the new USB charging standard which shorts d+ to d- to indicate it is a high capacity charger rather than a typical PC USB port trickle charge.
You can determine if your charger is compliant by plugging it into the phone and choosing settings, about, status, and see if the phone indicates "charging (AC)" or "charging (USB)". If AC, the phone will take 800mA, if USB, probably more like only 300mA.
I just took a look at my Better Battery Stats info and noticed a bluetooth and pbap related wakelock. As you can see 51 minutes, over 3 events. This is invariably during my commute.
I currently have my car stereo set up to access my phonebook from the phone rather than store the phonebook in the stereo. I have a theory that this scenario is battery intensive. I'll test this by placing my phonebook in the stereos memory.
Were you using bluetooth during your trip? Is your phonebook stored in the bluetooth device or does the bluetooth device access it through your phone?

I noticed that my phone will not charge the battery if it is too hot (30 degrees?). So if you drive with your phone exposed to the direct sun then it will probably not going to charge the battery or reduce the charging current.

[Q] 2A wireless car charger

Anyone seen it?
The ones sold are 1A which is rather slow for charging, i plan on using it for GPS + music so i'm not sure if 1A is enough to charge it.
The only 2A wireless i've found is this:

For those who bought it, how thick is it?
I'm thinking of combining it with brodit / ibolt dock....
Ohh, you can purchase a USB car charger with two USB ports. So you can charge you phone with your USB charging cable and also charge your GPS or Tablet.

I meant i use GPS and music on my note 3, So it will charge very slowly or maybe not charging at all if i use 1A wireless
There are a few threads that cover wireless charging. You find some info there. You are not likely to find a 2Amp wireless charger.
- Wireless charging will be slower than wired.
- It is more inefficient and produces more heat
- Most devices are limited to charging at something under 1Amp or even 500mA (as to minimize the heat produced).
- A custom kernel may be able to raise the charging ability of the device, but probably not over 1Amp.
No matter what you do 640ma is the charging current so a 1 amp charger will work fine

So this is false ad? Or just marketing gimmicks cause the max is 640mA?

2Amp charger powers the pad. The pad puts out 1Amp to the device.
Like I said there are threads discussing wireless chargers in this and in the Note 2 section. The Note 2 section is little older and has lots of info. It even discuss that Samsung charger.

How Do I Know If My Mi 9 is Charging at QC 4.0 Speeds

Hi Guys
Just purchased a Xiaomi Mi 9 along with a razer charger QC 4.0 charger and was wondering if the phone gives any indication that you are charging at QC 4.0 speeds.
Download "Ampere" to see at what rate your phone charges.
Thanks just downloaded the application.
Any particular stats within the app to look out for

Just the charging speed, QC4+ should be around 4A, if I'm not mistaken? Haven't checked, but I think that's about what you should get. My Mi 9 charges at 3.3A with the stock adapter.

I bought the Belkin QC4+ charger and it seems to charge the same at the stock Chinese model (8/128) adapter.
Mid 4000s mAh @4.4v
Take it for what you will. I bet anything is better than the Global brick I guess.
I know it's working because my phone charges absurdly fast.
Look for rapid charging on lock screen
Or charge turbo on charge animation
I am using the Hama QC4+ charger, no Charge Turbo and no Charge Quick/Fast displayed.
Wonderful charger
It does charge kinda quick, and the text shows Charging Fast, but that's it. Disappointed.
Could always use one of these, they're fairly cheap and quite usefull for checking port/usb output
or you simply look at the GSI lockscreen which integrates usb meter
shows volts, ampers, temperature, battery% and speed status

The charger that comes with the Chinese model should be a qc4+ one.

This was not my experience at all. I bought that belkin 4.0+ and it averaged at 2200... I don't think the phone does Charge Turbo or even Fast on 4.0 / 4.0 + because it isn't really a QC 4 rated phone. Offical Xiaomi chargers that do 27 w are running at QC 3.0 (look closely at the brick) they do however have an extra mode which makes the QC 3.0 charge TURBO... here is the confusion I beleive after buying a Hama 4.0+ and this Belkin 4.0+ you said works but doesn't charge Turbo.

But I connected this charger to wireless charger and I gave almost 4000. Who is know please explain me, how can I get more from wireless charger than charger itself?
By the way charger I bought from AliExpress, original Xiaomi 27w charger

ROG 2 30W Watt Charging

HOW DO I ACTIVATE HYPERCHARGING WITHOUT ASUS ORIGINAL 30W CHARGER​
I have ROG2 bought in India..
Box came with standard 18W Charger which charges phone around in 2 Hours from 0 to 100%.
Now i read about 30W charger available from Asus possibly which charge phone at 12V & 2.5Amps.
i tried various chargers like Baseus 12V 2.5A Type C to Type C and also thru normal QC 4.0 Port. But no charger is able to charge at 12V.
however i have Aukey Multiport Charger also which is able to charge my Phone at 12V but Ampere is 1.5A Max. but device doesn't show any hypercharging msg...
suggest me charger which can charger at 30W i.e. HyperCharging my ROG2
I have tried all kind of chargers.From 10W to 40W. Only Asus's 30W charger would make the ROGPHONE 2 HyperCharge.
Thats looks right, only asus 30w can do that...
But the difference btw hyper and fast charging is only like 1.5 hrs vs 2 hrs right ?
I also tencent with 18w charger

I tested loads. In the end I stuck with the 18w as the 30w is way over priced. I charge the thing slow over night anyway....
The phone actually charges a little faster if you use an 30W (or stronger) PD charger. When charging from 20 to 80% it saved me about 15 Minutes (reproducible), so I guess 0 to 100 it should be about half an hour, probably a little less. It falls somewhere in between the 18W and the 30W charger from Asus.
The 30W charger is good if you forgot to charge and you need battery. Otherwise the 18W charger is enough.

though hypercharge message doesn't show on Mobile, but above aukye charger is able to charge ROG2 at 12V & 1.5A max. that's 18W. I observe because aukey charger is rated at 12V 1.5amp max so it cant go beyond 1.5Amp.
I need to look for aukey Charger with 12V 2.5Amp rating and try it....
Aukey Model PA-T1 available on Alixpress.
