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.

I tried the Samsung Galaxy Note 4 quick charger on my ZE550KL 2GB ram model. The starting battery percent was 18% and after about half an hour the battery was still at 42%. I read on Qualcomm's website that SD410 supports quick charging 2.0. But the results speak otherwise. Could it be the software restricting quick charge?

I thought that only the SD 615 version of the ZE550KL was quick charge compatible.
The 410 is also quick charge compliant as well. Check this

The processor supports quick charge, but as far as I know, it's not implemented in the phone.
Yes I tried it too recently and the best rate at which phone charging was 1.1A (I used 2.1A charger, it took 3 hrs to charge from 10% to 100%)
Either we should all ask ASUS to enable fast charging in coming updates or wait for someone to build custom kernel that supports fast charging.
if it's any consolation, the moto g3 also doesn't supports quick charging. It also has SD 410. 3 hours is the time is takes for me to charge it to full with the provided OEM charger as well.

I had Moto G 2015 for couple of weeks. Didn't really use wall charger enough, I used USB charging through PC most of the times so can't really say about charging time.
I found some references online they claimed Moto g3 does charge faster, here is one...
http://forum.xda-developers.com/2015-moto-g/help/charge-time-t3171725
As far as the laser is concerned, has anyone raised this issue with them on forums?
can't bear slow charging :crying:
It more than likely has to do with the USB configuration so I doubt any software update will enable that, but to be fair it could be a software based limitation. The USB component needs to allow for the high throughput though.
I personally don't feel too negative about the charge time because I came from an iPhone 5S that doesn't have quickcharging. I am sure for others it is like watching paint dry though.
What I find most disturbing about the phone is that, it came with a 1A charger. You can save some significant charging time if yo use a standard 2A charger.

Have you tested this? Devices will only pull what they are able from a charger so if it was designed to drawl up to 1.35A then even with a 2A charger it will only drawl 1.35A.

I think you are right on this. I just tested and even with a 2A charger it takes more than 3 hours to charge the phone.
Anyone tried using qualcomm 2.0 certified quick chargers?
From this zentalk link, looks like my suspicion was correct. Event though SD 410 supports quickcharge, Asus limited the circuits etc. to not take 2A. Sad!
At least it charges faster on super saving mode.
35% in 60 mins on Normal mode
41% in 60 mins on super saving mode

My ZE601KL comes with a 2A charger in the box. I would say it charges quick when battery is real low and slows down when it close to 80% to complete the rest of the charging cycle.

Quick charge is supposed to charge from 0 to 60% in 30 minutes then slow to normal speed.

Are you sure that quick charge works?
What kernel are you using?
Hello everyone,
my phone is charging with only max 1A, when my charger gives more power. How to remove limit in my phone to get more intensity?
I don't think it is possible. The charging circuit within the phone only lets 1 amp in.
Fast Charge is a hardware limit too?

I am not really sure but it can be managed in the kernel if the hardware supports and fast charging is not supported by this phone. Btw Im not 100% sure
I believe the feature has to be in the SoC, as well as implemented in the kernel for it to work. I know with the Redmi Note 3 quick charging was not supported in the original firmware, but since the Snapdragon 650 supported QC 2, custom kernels were able to use it. The Snapdragon 410 doesn't have quick charge capability to my knowledge.
EDIT
It appears the 410 does support quick charging, and the OEM has to support it. Wether that means A software or hardware implementation, I'm not sure. So maybe it is possible for a custom kernel to implement the feature. But there is not any kernel I know of right now that allows it
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.
If yes, Then let me know which brand of charger should i buy!
No.
I think it only supports QC 2.0, though the QC 2.0 charger does not come out of the box. But imo, who needs fast charging when the battery life can last up to 2-3 days with this phone.
in it's specs sheet in gsmarena quick charge 3.0 is listed. That's why i asked.
anyway, what's the best quick charge 2.0 charger out there? and will that charge the device faster than the original charger?

The 625 snapdragon processor does support Quick Charge 3.0, but Xiaomi prohibits using it i guess to cut cost, i know some user who try to use QC 3.0 on this phone but it doesn't work, to be honest i'm also not sure about QC 2.0, my advice is you should try testing it first by borrowing QC 2.0 charger with some of your friends/relatives that has QC 2.0 charger before attempting to buy one.

No QC 2.0 support for me, tested with new xiaomi powerbank 10000mAh, ampere show max usb current 500 mAh instead of 2000 mAh. However from measurement I can get 1700-2000mAh so still charging fast enough.
Redmi 4 supports Fast Charging (i.e. about 2A), not any form of Quick Charge. The chipset supports it, but as Xiaomi have decided not to pay Qualcomm the royalties they charge for QC, it's disabled at a low level in the phone. It might be possible to enable it via custom kernel, but I don't think it's been done yet if so.

you mean that from the measurement you're getting a CURRENT reading of 1.700 to 2.000 Amps, right? Because mAh is the capacity measurement while A or mA is the current measurement?
To be on topic, the hardware inside (global version - snapdragon) and the battery support QC v1-3 specs but quickcharge is disabled.
The phone will charge at 1.8A or 1800 mA for about 10 minutes between 20% and 55%. battery capacity.
the current raise up while you changed to a qc 3.0 adapter.

CURRENT WILL NOT RAISE ABOVE 2A by now. ONLY VOLTAGE WILL BE INCREASE, but with decreasing current.
I tested a bit :
with QC 3 compactible Aukey PA-T16 charger, Ampere shows 2030mA
with Anker 40W 5 port charger Ampere shows 1830mA.
I have a Redmi 4 (standard edition) and I also have a USB Ammeter/Voltmeter which I can use to measure actual voltage and current flow into the device.
Using a standard 2A charger, the device accepts 4.9-5.1v (average 5.0v) at 1.5A (1500ma), and rarely exceeds this due to the voltage drop of the charger circuit /transformer in the wall plug.
Using a Quick Charge 3.0 charger (Capable of 5v, 9v, 12v and dynamically 5v-12v for QC3.0), I was able to charge the Redmi 4 at 6.2v/2.1A. The peak voltage was 6.24V and peak current 2.4A (momentary).
The Redmi 4 will charge at 6.2v and 2.1A with a Quick Charge 3.0 compatible charger when the battery is totally flat. As with all batteries the current slowly decreases as the internal resistance of the battery increases as it charges.
This is 13 Watts of power, 1.7 times higher than the 7.5 watts provided by the included '2A' charger. Thus, while it does not officially have QC3.0 capability, the device is still able to utilise a slight boost from the chipset's compatibility with higher voltages. Realistically, this means you could cut down on the charge time by around 1/3, and even moreso when charging from, for example, 0%-30%.
hi guys, eventually I find a solution for ghost touch issues.
1. flash agni kernel 13,
2. enable focaltech FT5346 forced,
3. and set qc 2.0 9v suppression mode to "suppression".
works for me, try that.
I'm using qc2 xiaomi charger 2.5A on 5v, 2 on 9, 1.5 on 12.

why? i checked sometimes, battery and cpu temperature came up to 45 degree only.
by non-quickcharger, battery full time is 2 and half hours but by quickcharger takes only 1 and half. 1 hour for 60%.

Because this phone has firmware bug. Hardware is limited to 5V, but Xiaomi made a mistake in firmware (not in the ROM) and enabled charging at 9V and 12V. So if you charge with QC, V is not limited to 5V by firmware and Zener diode on charging port or/and motherboard blows away, and You will have charging problem.

Its charging board flaw. There is no proper circuit switch control to stabilize the voltage from high voltage quick charger.
