Is it possible to supply a high capacity battery? For example from k20 pro, 9lite, etc. Does anyone have similar experience? My wireless charging is not working and i'm ready to disconnect and remove it

I am very annoyed about the charging abilities of the gnote cause when it's charging It continues to use power only from the battery, can't even take out the battery that the phone turns off while connected to the charger.
This leads to the battery discharging even when connected to the charger under heavy load usages such as playing 1080p through MHL, at least to me that happens, I wonder if same thing happens to other gnote owners? (I tried a 2A charger with the MHL and it doesn't discharge as fast, but still does, and I haven't tried yet cause i didnt find the Y cable on sale to do it, but i wanna get a Y microusb cable to connect 2 chargers at same time, one to MHL device and another to the gnote to see if that helps).
So i was doing some light reading on the gnote's smb328 charger circuit and according to their diagram (and from what I understand of it and their datasheet, I can be wrong ofc) the system should indeed be able to be powered by the charger alone.
The smb328 has a missing battery detect function and loads of settings that can be programmed on the fly through the kernel (I think) and through a windows program.
Now i don't know if it's that missing battery function or some other similar thing that doesn't allow the phone to remain on while connected to charger without battery, but whatever it is I guess if that could be circumvented it would also mean that the phone would also be powered by the charger instead of the battery alone.
So does anybody more knowledgeable in these things know if there's any setting to change the behaviour of the charger circuit to allow removal of battery while connected to charger or simply allow the system to be powered at the same time by the charger and battery so that under heavy load circumstances the battery wouldn't actually discharge?
Or is it the way that Samsung physically assembled the hardware that doesn't allow it?
Just throwing and idea to the air, but could a mod, like shunting 2 of the battery's pins or something similar allow to share the charger's power to the system?
Regarding the windows summitmicro smb328 program, you think it would have access to the smb328 circuit in the gnote if we tried?
Hi Elusivo,
I'm busy to fix my Note's charging circuit and R619 seems to be shorted. I've bveen all over and cannot seem to get the value for this register.
The datasheet I found from he summit site (from your link) does not help at all. Do you have a data sheet with an application note which specifies this value?
Help will be appreciated

As many of you, I struggle with charging my Note.
I've recently bought a 2.5A charger but struggling to find a good cable that can handle it. When using my stock charger with it and playing games etc. my battery slowly depletes. I did buy a cable from the same company as the charger that is designed for the higher power and does work as expected, makes charging quicker and actually charges while playing games, the only problem is the connection is loose a slight move of the phone and it stops charging.
So does anyone have any recommendations and success stories when charging their note?
For those curious this is the charger: http://www.amazon.co.uk/PortaPow-Qu...=UTF8&qid=1365954674&sr=8-1&keywords=portapow
do rooted/custom roms enable this or is this a hardware limitation? I understand its a temperature related issue. I am not saying fast charge while using overlclocked cpu and playing games. It just seems a tad annyoing that i cant charge my phone while driving in my car and navigating at the same time. (it will charge but only so very slowly....)
i am talking about the "adaptive fast charge" which really only fats charges when the screen is off or in AOD (always on display)
When you, lets say, have google maps open while driving the "fast charging indication is actually lying to you. It will only draw about 5 Watts there.

I see someone wants to recreate a newer Note 7. I don't think is is a hardware limitation, of the physical phone or the stock charger, but the (stability of the) battery itself. Playing a game at full brightness would require adaptive fast charging to generate too much heat in the battery itself to compensate for the rapid battery drain, and maxing out the factory charging cable to replenish what was lost during current use and charge the phone in the same quick time you are accustomed to (with the screen off).
You are really asking another Note 7 disaster

haha not quite. i think you are confusing some concepts here. The net energy / charge arriving at the battery is actually less when the device would be under full load because the device itself uses a portion of the energy supplied by the charger... or am i missing something?
I think the gpu/cpu/screen heat in combination with charging is what the issue was on the Note 7. The battery itself can, as it might be obvious, easily be charged with ~15w. I believe the smart solution here would be to simply reduce/throttle charging with relation to CPU/battery temp.
I can tell you that when in a holder in an air conditioned car using google maps the battery will be fine with quick charge unless there is some weird coupling between two ICs.
Any decent quality USB cable will not be a limiting factor. 2 Amps @ 5V or 9V is really not a problem/
My measurements with the factory cable and charger at about 85% battery were around 1 Amp @ 5 Volt with screen ON and about 1.67 Amps @ 9Volts with screen Off or AOD on.
anyways. really only wondering if custom ROMS support this is or not. having my phone quick charge in my car while navigating is very important to me.
I think Samsung just played it very very very Safe after the Disaster. Limiting current and battery size that a guy who quick charges his phone in a Sauna can play candycrush on max brightness in performance mode....

I agree, I should have made that point clear in the first post.

Samsung smartly chose to avoid the issue altogether.
Heat dissipation will be that issue to contend with in my opinion. My phone's charger only does 18Watts on a good day (screen-off) in an airconditioned room (measured by a USB multimeter). There needs to be adequate overhead left in the thin stock cable that is shipped with these phones (which isn't even USB 3.0).
I believe that this maybe an safety feature built in by Samsung in the wake of the Note 7 battery issue. There may not be a work around for it.

You aren't helping the OP's case in trying to re-create another (explosive) Note7. Suggest something nerdy, like creating a custom kernel that tricks the charging circuit into thinking that the screen is off when the the charger is connected.
I wanted to know if anyone has the same problem with charging as me. if I use the original battery charger the recharge is more or less that indicated (it takes about 10-15 minutes longer). the problem happens when i connect it to a laptop or car. I connected it to my car via an adapter that goes into the cigarette lighter and cable that I used with my redmi 9s. the battery is charging but does not increase. same thing happens with my laptop on standby. with my redmi 9s even though it slowly increased the battery. does someone else have the same problem (software optimization?), or is it not a problem because it absorbs more energy and I cannot make the comparison with the two smartphones?
edit: after a few days of testing I saw that the recharge takes place with the laptop or the car if the battery exceeds 60% otherwise this does not increase.
I have both the x90 pro and 90 pro plus. origin os. interesting question because I feel that mixing and matching chargers doe not charge at the max speed of charger/unit. so, given same cable length of 6a cable (or same cable) :
would the vivo x90 pro 120w charger be able to charge the vivo x90 pro plus at 80 watts? and would the 80 watt vivo x90 pro plus charger be able to charge vivo x90 pro at 80 Watts?
I also posted this on this website(
). I just feel that they dont do so.
Just food for thought..thanks
The x90 Pro plus never charges above 60w... (mayb 10 seconds - but surely never for a full minute!) - can easily measure this with a powermeter. This does not matter if switched on or off.
Also even worse there is no hardware to stop charging - go into bootloade fully charged and leave it connected - phone will get very hot once fully chargd as vivo messed up something there.
And yeah it's hypersensibl based on the cable. Some cable charging my laptop at 60 watts (max speed for my laptop - actually on a 65w brick) will only give 3-10w. Others are better and allow 20w (the max for 3rd party chargers)

Interesting. I was wondering about the message "fully charged, remove immediately".. I mean silly .. what if you want to charge it overnight.. I have to say (again I don't have a power meter.. yet.. ),the x90 pro with 120 watts brick charges so so quickly ... Anyways thanks for the feedback .. ps:both units I disabled smart charging option or the option that learns your usage etc..
in bootloader it's worse than trickle charge - if phone is on or off it's trickle charge - in bootloader it's like 6-7w pushed in that need to get rid via thermals. It's really crazy vivo saved some pennies on hardware charge protection (on third party chargers at least - maybe the vivo charger brick that I don't use because it's way too big for the power has some inbuilt protection).
But clearly even on the own charger there is no like charge to 100% - go down to 97% - then shortcut the battery or similar. It's a great way to destroy the battery quickly though.
