[Snapdragon] Quick Charge 2.0 hardware is built-in but not enabled - Xiaomi Redmi Note 3 Questions & Answers

LINK : qualcomm.com/documents/quick-charge-device-list
According to this PDF from Qualcomm that lists QC3 and QC2 devices, the Xiaomi Redmi Note 3 "contains the hardware necessary to achieve Quick Charge 2.0" (page 4, bottom right).
Apparently Xiaomi has not enabled the feature. But it can probably be enabled by modifying the kernel.
Can the developers confirm that this can be done?

@Luiggi79 Agreed. But the RN3 does not have the required antennae for NFC, even though the SD650 supports it.
However, it does have compatibility for QuickCharge 2.0 and I believe it could be enable in the kernel. (I don't know about QC3.0 since the document does not say so).
This is similar to the LG G2 which had official support for QC1.0, but could successfully achieve QC2.0 using custom kernel.

what are the chances of getting this working?
And why did xiaomi not include something which the chipset supports?
Both those features would have made this a killer handset, are they that much more expensive to implement?

If it has the hardware capability then it should definitely work. But the battery should be able to handle it too.
Xiaomi probably didn't enable it because they did not have licencing for this handset. It would add to the cost I guess.

What charger are you using ? I haven't used official charger I am using my Samsung charger which is just a standard 2.0A charger from my Note 3 or something. Phone doesn't warm up even a little bit. In fact I haven't felt this phone warm up ever, even after 30 mins of GPS use or charging. Unusual !

Some developers have already been testing quick charge and apparently it is working. Of course, no one knows what effects it could have mid and long term. I believe it was in on of the cyanogenmod rom threads.
>1080p external display support
Since the RN3 does not support an external display officially but the 650 does, I was wondering if this could be enabled by software like quick charge or does it need some special hardware connection like nfc? Anyone knows? Would love to be able to connect the RN3 to an external display.

Can confirm that it does not get hot at all while charging, using the original 2A charger that came with the device.

I use a simple trick to counter the charging heat, remove back cover if u use any, put ur mobile on slightly damp cloth while charging. That's it.

Fast charging works on my device 1 hr to full charge

hmmm
Then ,sir, tell us how u do that ??

AFAIK, to have full support for Quick Charge 2.0/3.0 on any Snapdragon device, in this case for Redmi Note 3
- The Hardware (SoC) should be compatible for QC. (Present)
- The OEM should pay the licensing fee for QC to Qualcomm. Around 5$ per device for QC 2.0 (Absent)
- The Kernel should have QC enabled. (Absent)
- The Power Management Integrated Circuit (PMIC) should be capable of handling QC. (Not sure)
- The Battery should be capable of rapid charging via QC. (Not Sure)

Do you know if external display support, be it MHL or SlimPort, could be enabled the same way or needs extra hardware so it is not possible?

its fake claim of custom kernel creator here...............1 hr for 4050 mah is impossible, as per the Qualcomm list of supported device RN3 supports QC 2.0, May be users and forums plague with heating issue on its launch,so they blocked at kernel level and also to save costs on Qc2.0 Supported charger, please stop bluffing as jackXXx,. even if he is skilled to code, 1hr is impossible. mi5 takes 1 hour + with 3000mah battery. qc1.0 qc2.0 qc3.0 times will be 2h 50mts, 2 hrs 10mts, 1hr 35mts. thnks to thread creator for finding it listed in qualcomm page.

Surprised to read this, can u share that kernel?

What it's the list of better GPS Chipset in MTK Processators

What it's the list of the better GPS Chipset in MTK Processors.
In the past I start in Android with the FG8, a Mediatek MTK6516 416 MHz processor and with that phone I have the best GPS ever!
I can connect in only 20 second to more than 12 satelites.
Them, I have 3 phone, all with MTK6573, 650MHz+350MHz and had the worst GPS ever!
Now, I'm waiting my new phone (a Huawei) with MTK6577 (and I don't know the quality it's the GPS).
But why MTK? because I need dual-sim phones and Qualcomm don't have a lot of phone dual-sim.
So my question it's: anyone have or know a list of the best GPS Chipsets? I use a lot of offline maps and I don't have connection (wifi-3g) most part of the time)
Thanks for all for read this
I fear the difference you experienced has more to do with the other components than the MTK chipset.
Especially shape, quality and placement of the antenna is probably the big difference. Though calibration data of the antenna in the radio firmware may also matter (on the 6516 you had to take care not to loose the calibration data when you formatted flash)
And of course, the antenna is determined by the builder, and how cheap/hasty they are making the phone. For example, despite your experience, my MT6516 HD9 was not soo good at all. My MT6575 A750 is better, but not as good as my specialized Garmin GPSMAN60GS, which has a 3 cubic cm quad helix antenna. You'll never see those in a cell phone.
I suspect the actualy GPS sub-chip is pretty much the same in all modern Mediatek chips. After all, MTK was originally a GPS-only chipmaker, and have been making those for 10 years or so, so so they fixed all the early errors.
PS: There is one 'GPS' change I hope they will put on the new MT6589 chip: GLONAS support. But to repeat, I am sure all of 16, 73, 75, 77 have the same GPS sub-chip
Thanks

I don't know that details, thanks a lot for the information. I must see and search my next phone be an MTK6589 or better. I ear about Glonas of Qualcomm but I must use a dual-sim phone and Qualcomm has little amount of diversity in dual-sim smartphones.
Thanks again!
No that's not what I meant. It was just an extra remark.
In fact, as they might (so I hope) add a new GPS sub-chip in the MT6589, thats when you could see improvements, or new early adoption mistakes.
The MT6577 is a safe bet, its GPS subchip has been stable for years now and I am sure it's GPS is as good as the MT6516 was, provided the phone builder did not mess up the antenna.
My hope for Glonass is only a hope. What is known about the MT6589 is that it will be somewhat faster than the MT6577 (4 core rather then 2 core, but only A7 cores, not A9), but a lot more energy efficient (again A7 cores rather then A9)
You could wait for the MT6589, it will be a few more months, but the first models may be priced too high (shopkeepers will want to milk it) so reasonable prices may be only in March/April or so.
Thanks for the info again! I do not know that.
I think I must wait Best regards!!
(I hope too the MT6589 have a better GPS)

Indeed, at least since MT65x3 the sub-chip used is MT6620, which integrates WLAN, BT, GPS and FM into a single chip.

Thanks for this post it explains why my mtk6575 i phone clone gets a lock much quicker than my 6577 s3 clone clearly the attenna is placed properly in the 6575 it slightly bugs me because they both have the same GPS chip as you said.

Thanks!
yeah new toys
heh new remix os device.
Does anyone see where it says what chip they are using for this. I would HATE to get this like the Mini and be stuck on a device that will NOT get updates in the future. 2GB is also very much on the low side for a console you would like to run games on.

Exactly. The 2GB RAM can still be tolerated when the Remix Mini was first dreamed up last year (2015) but a BIG no-no for a 2017 model. Not with this NEW Remix IO.
Speaking of performance, I wonder why didn't they go for some SoC that has at least the ARM Cortex-A72 cluster in addition to the low power Cortex-A53 cluster to improve performance.

Possibly for cost but I have been reading where they may address the RAM. I dont know if that will make it to the Kickstarter buyers.

Chip with a least a pair of Big-Core (ARM Cortex-A72 or something along that line) in addition to the cluster of Small-Core (ARM Cortex-A53) from a manufacturer that is better in term of Android support than the one in Remix Mini who refused to cooperate with Remix on the Marshmallow upgrade. We don't want the same disaster, do we?

Well Intel tryed to build some atom phones with the asus zenphone 2 so I'm not sure but it can be comparable. Anyway low consumption and big little is useless with a tv box without battery...no limit in power here. It use a wall socket after all.
But I can imagine a nice tv box with a cherry trail atom.
And the uefi part mean: you can mod a system yourself.

To be fair to ARM and its big.LITTLE™, low power is not useless. All things being equal, low power can also be translated into less heat. I'm sure you know what less heat means to longevity, packaging etc of a product.

well no mostly because I live near a desert area so all those passive TV boxes overheat here what ever CPU they have. I know a fan add a failure point but a fan is just needed here.
most computer we build here have oversized coolers.
so this is why I am interested with the Io having a fan.
and to me usability comes first with performance.
this is not a phone after all

Nope! We have to wait for the Kernel Sources to release. Then you can expect some custom kernels with fast charging!
Kernel sources​ are out now. When will we get qc or a custom kernel. Are there any custom kernels on construction
Is there any proccess on QC enabling? Maybe someone needs any help in it?
According to devs, enabling quick charge will damage your phone.
don't, our battery and motherboard doesn't support quick charging

RN4 model, how to be sure

Hi guys,
I just gor my RN4 which was advertise as 4/64 Global with snap 625 cpu.
The fact is that Antutu says it's a mediateck cpu while Droid Hrrware info and CPU-Z say that it's a snap625 !
Also according to kimovil (where you may go by your own as I can't insert links), Global version are supposed to be equipped with a sony imx258 sensor while non global version with a samsung S5K3L8.
Mine came with a samsung sensor, but I've seen it happend a lot to RN4X, but did not hear that about RN4 global.
Do you have any recomendation to have a solid answer what my cpu is, and if I do have the 4G band of a global version.
Lastly any reliable plans to get a imx258 sensor from somewhere ?
Thank's in advance

It literally says on the box if you have Mediatek or Snapdragon chip. What does it say on the box on the back, next to " Product Name / Product Model: Mobile Phone / XXXXXXXX", reply with the number.

Not true, it's 100% random between 3 camera sensors.
It's indeed all writtent on the box, global with snap 625 !

And for the sensor, I'm a bit frustrated not to get the sony, but I may feel happy not to get the omnivision, so glass half full

Most of the time benchmark and device info apps don't read info from the device, but read them from a server which has a library of device infos. So it could have been possible that antutu judged your device incorrectly. The most basic difference by which you can get your cpu type is by checking the number of cores. Mediatek Variant has 10 cores. While the Snapdragon one has 8.
yop that's also what I assumed, but that's lame...
Anyhow I could also very fy that I have a snapdragon cpu in the settings > about this phone > Cpu > octocore 2.0GHz.
waiting for 72 and I'll unlock it.

150Mb wifi link

Hi there
I'm trying to achieve the best bandwidth over wifi which i need for local file transfer, but strangely enough my Redmi note 4x (Mido) can't get any higher than 150 Mbps link speed over wifi.
My router Asus rt-ac3100 can handle way more than that.
Looking at SD625 specs reveal that the SOC can peak up to 364Mbps.
I used a bunch of 7.1 and 8.1 ROMs but they all have the same results
So i'm wondering what is the limiting factor, and if there is anything to bypass it
The phone's WiFi chipset only supports N bands. It's a/b/g/n only. Though you'd think it'd connect a bit higher, since N allows for 600Mbps. My laptop is stuck with an Intel a/b/g/n card and I get a link speed of 240 to 270Mbps when connected via 5 Ghz.
How far away is your router? My router is in my room, where I am right now with all my devices. Though the link speed on my Note 4 is still capped to 150Mbps. Strange. Don't know if it's a fixed hardware limit or something else. I previously checked on MIUI and now on LOS 15.1. Both show the same 150Mbps link speed.
My LeEco x722 (SD820, 802.11ac WiFi) got 866Mbps easily. I also had another Snapdragon 625 phone, but with AC WiFi. It too got a pretty high link speed of around 600Mbps. I think the issue is that the wireless chipset in the Note 4 is very poor.

The router is in the same room as i am with no obstacles between.
I found (at gsmarena.com) that Mido only support up to wifi N (no AC) even though the SoC support AC standard, probably due to the implantation of cheap radio hardware, and because most phones optimized for efficiency it run only on a single radio band that is why 150Mbit and not the 300/600mb advertised even for wifi N standard.
The news left me disappointed, for a top midrange phone not to support AC, i guess something to consider in my next phone
The twin brother of mido the Mi A1 which is literally a Redmi note 4x play edition support AC wifi. Moreover the Mediatec version (nickel) also support AC wifi, so why xiaomi left the redmi note 4x without?
The more i dive the more i feel betrayal.

I believe it is a driver from the firmware and/or kernel that doesn't allow full speed N or AC to work. I have looked into most of the software and cannot find what is stopping it.
Try wired connection by buying usb adapter maybe? Have you tried flashing latest dev firmware along with rom that might help.

Wired connection is not an option for a phone. I tried both stable and dev firmware with a bunch of roms and it is always the same 150 Mbit link.
Gsmarena listed the phone as Wi-Fi 802.11 a/b/g/n enabled device. So it it official, no AC for mido
