Hi,
My Atrix does not have any Problems with charging when connected to my PC, but it just wont detect the external Battery i own.
It shows no reaction, when the Battery is plugged in via USB and then turned on.
When the phone is off and the battery is connected and turned on, the phone will boot, but still not charge.
I was trying to find out why the Phone won't accept the Battery so I measured the outgoing Voltage: 6,3 V
Note: 2 out of 2 other phones (1 running Android) detected the battery and charged from it without any issues.
The external Battery was really expensive since it comes with a large solar panel to charge it, so I really ought to get this to work!
Does anyone have any Idea what I can do to force my phone into USB-charging mode? Or how to make it detect the battery?
Greetings,

I know
And I tested today. You must put resistor about 200OHM or just short data pins (2 and 3) in your charger or cable. I really recommend to put resistor. Interested thing is that after phone is connected you can remove resistor and charging will continue.

Thank you VERY much for your effort!
Why wouldn't you recommend just shortening D+ and D- on the Type-A-side? what could happen? Wouldn't that just make the resistance infinitively high?
Also, Why does it work with other phones, if it's the battery's / cable's fault?
I know those are a lot of questions, but I would really apreciate it if you took the time to answer them.
Greetings,

Edit: just realised I misunderstood Zeljko. I thought by "short data pins" he meant to clip them off so they couldn't connect to the device
Of course he meant short circuiting them^^
Because shorting electronic circuit could damage it. Better safe than sorry. I tested today and even 330kOhm works.
Other phones obviously doesn't care about data pins. Probably Motorola wish to protect phone from low quality third party chargers.
I followed your advice and soldered a 200 Ohm resistor between D+ and D- coming from the Mirco-USB-side.
I just insulated the D+ and D- of the Type-A-USB-side
I actually followed a REALLY useful (German) Guide for things of this type: Sorry It appears I can't post links...
Sadly, I can't test wether it works at the moment, because my phone is being repaired (touchscreen broken).
If you are interested I can tell you wether it works, as soon as I get my phone back.
regards,
XxHunterxX
I know it works, I tested by myself
Could you send me link? I think you can post link around code tag or picture or just figure out somehow
Is your charger a Minty Boost? I have a Minty Boost and it always over heats when i try to charge my Atrix :\
:EDIT: Also I tried shorting out D+ and D- with no avail. It charges but quickly overheats

It's cheap chinese charger. I just used it once for testing and I didn't noticed any overheats. I bought it for cycling but I'm traveling a lot and unfortunately I don't have time for long ride.

If your charger overheats then the worst you can do is short the D+ and D-!
Because then your phone will detect it as a charger and will draw not only 500mA, but even more so your charger will overheat even faster.
You should probably just buy a charger that isn't so cheap

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 )
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.
Hey guys, just wanted to know if anyone could recommend a brand that offers 2.0 quick charge on the go. I did some homework and the names Powermod and PureGear seem to pop up the most. Any suggestions? Thanks in advance
I had the powermod and it was slightly too small for my car outlet so if you bumped it then it would stop charging. I think I had a lemon but anyway I bought the incipio one and haven't looked back
Also, can I use any USB cable to receive the turbo charge? I'd hate to keep hauling around cables from my house back into my car.
http://www.amazon.com/Ventev-dashport-Charger-Single-Includes/dp/B00QU9DEBW
I have this and it's great. It's got a very low profile, came with a flat cable, has an LED light (albeit not very visible), and definitely charges quickly. Highly recommended.

Can you post a picture of the cable? Do they sell it separately? I was going to buy that one but it was hard to find back when I got my original QC 2.0 charger on early December.

I use this one as well. Any USB cable will work. I tried an old ASUS cable with my wife's Note 4 and it said a quick charger was enabled. That flat gray cable it comes with is really stiff and I drive a manual so it was always getting in my way when shifting. I switched to an old USB cable I have that's more floppy.
This doesn't sit flush with the port though even though the design makes it kind of look like it does. It sticks out about a centimeter or so. It would be super hard to get out of the vehicle if it sat flush.
Thanks for all the replies! i've decided i'm gonna go with the PureGear
http://www.amazon.com/PureGear-Qualcomm-Charge-Extreme-Charger/dp/B00QQPG57K
Pretty cheap on amazon and I like the design, will report back with my opinion on how it works
Sorry for resurrecting an old thread but does anyone know a very good quick charge 2.0 car charger with at least 2 USB ports? One port could be quick charge 2.0 and the other port could be normal or whatever.
I saw the choe one that has 4 points but its getting mixed reviews and I don't think I really need 4.
Thanks guys.
Yes just buy a power converter and use the OEM wall fast charger that came with phone.
Definitely not trying that in my car....
There made for cigarette lighters. Its perfectly normal. Most new cars have them built in.
I wanted to get the Ventev dashport charger, but they seem to be out everywhere, or ridiculously expensive in the places that do have them.
I want to try and get one thats as flush with the socket as possible, because theres already very little room in that spot in my car.
Found these two:
Aukey 4.8A / 24W Dual USB Car Charger Adapter for Apple and Android Devices (The Smallest but Most Powerful Car Charger in the World)
SCOSCHE USBC242M 12 Watt USB Car Charger for iPhone/iPad/iPod Lightning/Micro
I admittedly don't know much about, and neither of these are QC2. I was just wondering if anyone has used, or knows if they would work good. Would there be much of a diff between them and a QC2 one?
I just love the cables of WSKEN. I use them on most of my devices.
So also on the MI9... But sometimes I had more battery drain than other times.
I found the problem through BBS. The WSKEN connector activates a kernel wakelock. Which uses lots of energy.
It declares why I have it sometimes because I don't use the connectors all the time.
Now i am on Xiaomi.eu rom. Can other users on different rom with maybe the same cable report if they have the same or not?
Thanks.... It's a shame i can't use it anymore now I know this.
It's the WSKEN X1 Pro.

I think it's better to use wireless charging. I don't know why, but I'm not a fan of permanently putting something into the charging port...

Where do you think the leads of the wireless charging coil goes to?? [emoji848]. And wireless charging generates more heat.
And let's not talk about efficiency.... Wireless charging is around 60% so 30-40% of the energy got lost.
And the wireless charger I have got is very noisy.
I'm not unlocked and rooted so I can't use BBS, but I've got the WSKEN X1 and I haven't noticed a dramatic battery life.
EDIT : There is indeed a wakelock. I believe it might be due to pins being shorted by design. Like CC1 & CC2 (plug detection) being on all the time, and the phone constantly asking ("yes, who is it?") and getting no answer.
I'm writing to WSKEN about this (and dual magnetic cables) to see if it might be fixed in the future.
I use wsken cable for my mi 9, but most of the time it doesnt charge my phone, sometime it does.
The cable works perfectly on my micro usb plug, but not on my type-c plug (for wsken mini1 & mini2)
I've tried the cable and the type-c plug on another phones (not mi 9) and it works perfectly.
But my phones charge normally with the oem cable.
Anyone can help?
Sorry for bumping an old thread.
I'm using WSKEN mini 2 cable and the USB-C adapter on my Mi 9 which works flawlessly, no drainage and the phone charges every time.
So @24ilham I think that you might have a faulty USB-C adapter.

The drain is not very noticeable, but I got it too and decided to remove the USB-C Plug.
As I said in my edited post, I believe this comes from the 4x4 USB lines on the outside being fused towards the USB-C inside, which got 8x8 pins. To be reversible, I believe they are shorting VBUS and CC1 or CC2, and since it's used for Power-Delivery negociation, the phone is constantly asking "Ok, you're a PD Charger, what are you capable of?"
Unfortunately, the plug is too small for me to test removing a CC2 pin, and trying to find if it fixes it.
Someone with a lot of patience could try to use a USB-C cable with splitted CC2 wire to extend a plug, but... a lot of trouble.
@24ilham I believe you have a faulty USB-C plug as well, I have never had a problem with mine.
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.
