Quick Charge 2.0 by Qualccom

Our snapdragon 410 supports quick charge 2.0, is some hardware limitation in our device that dosn't allow to charge at a higher speed? the battery needs to be compatible? etc

Our battery only receives 5V/1A.

You need a 1.5 Ampere Quick Charge enabled charger to use that feature.
Xiaomi ships two kinds of chargers with the Redmi 2 ( based on region) : one is a 1.5A QC2. 0 charger and one is a 1.0A QC charger.
If you're looking to buy one, I'd recommend Microsoft Fast Charger

It can be enabled through kernel modifications.
As Redmi Note 3 has got the feature through Franco kernel.

Enable 2.1 or 2. 4 Amp charge input

All we need a basic feature to be enabled / developed by developers to kernel i.e Charge rate control.
Other features can be focused after this.
The most wanted feature we want from kernel is fast charge support.
Option to enable 2.1 or 2. 4 Amp charge input.
All other features are secondary.
To fully charge redmi 3s takes 3hrs. with input of 1.4 Amp.
Please work specially over this feature.
Whats your opinion?

Use Eximious Kernel ,Its capable with fast charge ,took 1hr45min from 30-100, You have to turn on usb fast charge by Kernel auditor . But dnt try to flash any custom kernel with miui base rom.

usb fast charge and quick charge are two different things. usb fast charge let you charge from pc like with regular charger and quick charge let you charge faster using fast charge charger.... stock charger is limited to 2A and no kernel implementation can change it....

redmi 2 fast charging, is it safe?

i have this feature on my phone's kernel atm, is it actually safe? because Redmi 2 itself doesn't support fast charging by default will it cause our battery to overheat? or even explode (lol)

Redmi 2 supports quick charge 2.0, however the charger sent by xiaomi does not have this technology. And yes, that support in the kernel is secure.

The Redmi 2 battery only accepts 5V/1.0A, so QC 2.0 isn't supported by hardware, altought the SD410 supports it.

Yes, but using a quick charge charger makes the battery charge 1A / h constant, which makes the charging much faster than using the charger sent by xiaomi

Does Redmi 3s support Quick Charge?

The Xiaomi India website doesn't mentions that it supports Qualcomm Quick Charge but there are some people who are saying that it supports Q.C. 1.0/2.0 and some even saying that it supports 3.0.
And the Xiaomi website states that “[it] Comes with 5V/2A quick charging to charge and go with minimal downtime.”. Interestingly enough, Quick Charge 1.0 also charges at 5V/2A.
Has anyone tried charging with Qualcomm Certified chargers and is there any long term issue like battery inflating, poor battery backup, etc?
And if it does work then what are the things I should be looking in a charger when buying apart from Qualcomm certified chargers?

The soc of our device does support quick charge, but to enable it, we need a suitable kernel

I think it's enabled on MIUI developer rom.

Yes. Some say that latest beta update miui 8.2.5 has total charging period of 2.5hr.

As per the super moderator in MIUI forum the Dev rom supports QC 2.0 and charging time is less than 2 Hrs.

Fast charging on custom ROM?

Fast charging has been most controversial topic for our Mi A1 device.
Is it possible to enable fast charging on custom ROM.?
I have read somewhere that our SoC supports Fast charging

It was a bug, MiA1 do not supports Quick Charge.

Yes I should think fast charging would be available on custom ROMs. We saw on phones like Redmi note 3 it was also enabled. Basically Xiaomi phones have all capabilities to fast charge, however the speculation is Xiaomi does not pay Qualcomm the license fees so they can't officially support it.
