HTC M9 force AC fastcharge? (with stock kernel, or a kernel recommendation)

Hello, so in theory this should be a sort of straightforward question, but I'm not sure there is a good solution yet. I've found that the M9 is veeeeeery conservative with charge speeds and rating chargers it deems worthy to give it fast charge speeds. With that comes many reputable third-party chargers giving the phone little to no juice, and I would like to override this.
So what I'm looking for is a way to tweak the charge speed allowed manually. On my Google Play Edition S4, this was called fastcharge (not quickcharge, not interested in buying one of those, as every charger I have has more than one usb port and I'd like to keep it that way). It was something that I found on a custom kernel and allowed you to set a max charge speed for both AC and USB charging (with AC being able to be tweaked all the way to 1900mAh).
With all that being said, does anyone know how to allow something like this with the stock kernel? I've seen a couple kernels that advertise this as a feature, but they also all seem to be in beta, and have bugs that aren't squashed yet. I'm on Viper 1.6 if that helps at all, and any help with this would be appreciated!

LeeDroid Kernel v2

and the LeeDroid kernel will work on Viper rom? Have you experienced any problems with it so far (if you're using it)

None here and have been using it for some time now. Very snappy, superb battery and very fast boot. Using with insert coin currently and controlling with "adiutor" kernel app. Working flawlessly here

Okay then. I'll do a nandroid and give it a try, thanks!

ElementalX is great

It's a shame that you find the HTC One M9 charge rate to be too slow but don't wish to do the only thing that will give impressively fast charging with stock software: obtain a Qualcomm certified fast charge 2.0
The fast charge capability comes from using chargers that use higher voltage than the standard 5 volt.
Higher voltage leads to higher charge current which shortens charge time.

I think you just need a 2A charger. I get very quick charge time with the Nexus 6 charger.
Why HTC didn't include this is beyond stupid. This thing is capable of charging to full in an hour or less
The thing kernels have is USB fastcharge, which increases the current when connected to a computer USB port.

Thing is, I have a ton of chargers that should be able to pull more than 2 amps, and have on other phones. I have an Anker one (with charge detection up to 2.4 a port I believe) and an Aukey one that's the same. Also have the stock HTC and Samsung S4 one, those do seem to pull about 1-1.5 out of it but the third party ones aren't doing anywhere near what they should be (normally getting betweeen 3-800 out of them, topping out at about 1 amp).
And yeah I've found that out about the kernels so far, USB only. I was thinking that based on the reading but I figured I would try. I wonder when/if an AC fast charge will be implemented, or if it even can (not sure how it works with quick charge 2.0 interfaces). My S4 did have the setting for both USB and AC so I was hoping to find the same for this. It's not a huge huge deal, but I would like it if possible. Or if a company could come out with a slightly affordable 4 or 5 port charger with at least one or two QC 2.0 slots that'd be lovely as well.

There's one on Amazon
It's from a manufacturer called CHOE or CHLOE
It's a 5 port charger with 2 ports capable of quick charge 2.0 and rest of the 3 ports upto 1.5 or 2 amps
It remains for 30ish

Yeah they were the first ones to get it and now a few others are too, but 35 is still just a liiiiiiiittle steep for me to pay. Thanks for looking out though, appreciate it.

What app are you guys using to check your charging speed? I used galaxy charging current on my S4, but it obviously doesn't work on this device. I've tried a few from the play store but nothing seems reliable.

Ampere is good. It had a hard time reading an octacore on a fast charger (one of those two was giving it issues) at first but recent updates seem to have sorted it out.

One simple question: fast charging

Hi,
CM roms or GPE ROMs support fast charging ? beacuse with my Samsung Fast charger it has a very slow charge like complete in 2-3 hours.
Thanks !

Samsung charger won't work on this device for fast/quick charging. You can blame Samsung for that (or for manufacturers not all using the same fast charge standard). Samsung does not use the Qualcomm QuickCharge standard, inherent in the Snapdragon chipsets. Samsung decided to use their own proprietary fast charge technology, which only works on their devices. Probably at least part of the reason, is that Samsung does not always use Snapdragon processors in their devices.
With the M8, you need to use a charger that specifically supports Quick Charge 2.0, which will either say QuickCharge 2.0, and/or have the QC logo like this: http://www.androidcentral.com/sites/androidcentral.com/themes/android_visor/images/badges/quick-charge.png
Also, QC 3.0 compliant chargers will also work on this device, but at QC 2.0 speeds (not the faster QC 3.0 charge rates). Might be a consideration if you are going to buy a QC charger, and want some "future proofing" for a possible future QC 3.0 device.
I was reading that some higher amp rated chargers (not QC compliant) may charge slightly faster with QC devices, but you'll never achieve full QC charge rates. And from what you're seeing (and others have reported similar) is that the Sammy charger doesn't give you any faster charging then the "standard" (non-QC) charger that came with the M8.
Not sure (not a CM or GPE user myself), but I believe with the proper charger, QC 2.0 will work on the device, regardless of the ROM, as the feature is built into the chipset hardware itself. But you can probably check the ROM threads to verify that.

Any suggestions on Dash chargers for Z2plus ?

Hello Everyone,
I am looking for a dash charger for z2plus , I just used my friends OP5 dash charger for z2 plus it works like a champ. But OP5 dash charger is expensive like 2k, any other suggestions on chargers ??
Thanks in Advacne !

I would say.. don't go for anything except original charger.. it can fry some important diodes on your board and I am not kidding happened to me twice...
First time, battery was empty, and phone never woke up, I had just installed custom rom maybe because of that...
Second, exchanged phone, new phone, stock everything.. and it happened again..
Then I realized it was because of the 3t charger...
Read few posts, and found out if used some qc 3 chargers it can fry the diodes cx68 something..
Better read those post before investing money...

Nonsense! QC tech and Dash Charge tech are totally different. If used, any oneplus dash charger will charge your Z2+ like a normal charger and not any faster. Dash Charge Tech is Oneplus's Proprietary and won't work on any other company phones. And Regard to Best QC3 Chargers, Only and Only buy & use Qualcomm approved QC chargers. They are tested by Qualcomm and will almost never cause any issues. The List of approved chargers can be found on Qualcomm's website.

After buying the Qualcomm Fast charger can this device charge quickly ???

The Zuk Z2 plus cannot quick charge (No QC2/QC3), atleast yet. Some say the hardware isn't present in the device but i believe with the other group that say it's locked in kernel. In the Fans page, a dev has posted a mod to enable QC 9V charging on kernel level. If you or anyone has QC charger feel free to try it (UNDER YOUR OWN RISKS). At Stock Charging Capabilities, the device can charge with 5.25V 2.5A max. You don't need QC chargers for this, the lenovo charger that comes in box is more than enough.
zukfans.eu/ community/ threads/ request-quick-charge-support-qc-3-0.2526/

1.5A on screen en 2.5A off screen all by 5V are the best charge number the z2 plus can do, so it does charge good but it's doesn't benefit from a dash or quickcharger like one plus phones do.
Quickcharging is charging at higher voltages for the same or sometimes even more amps. and since A*V= Watts you put more and faster the power in your battery

Is Xiaomi Quick Charger 3.0 okay?

I am really upset with my htc 10. It's battery is not okay. Yes it does charging so fast, but It lose charge so fast too.
What is the main problem of it???
And I use a normal HTC 3 pin Charger. I don't have qualcomm 3.0. And its difficult to found in my country.
Can I use Xiaomi Charger 3.0 for my HTC???

Don't know about the Xiaomi charger, although in theory, any certified Quick Charge 3 charger should work (as long as you use a good cable). And the phone is backwards compatible with older charging technology.
I am using my old HTC charger from the ONE V. It is just a normal 5V 1.0 A charger (USB 2.0 spec) and it worked. (I am doing that since I don't need the quick charge, and I figure the slower charging with lower battery temp might prolong its life.) A Quick Charge 2 charger (Samsung), and a USB 3.0 fast charger (5V, 2.4 A) also worked in my case.

Re-enabling QuickCharge 3.0 support?

Hi.
As you may know, ASUS (following the Samsung Note debacle) locked the fast charge capability of the Zenfone 3 Deluxe/Ultra to the included QC2.0-spec OEM charger with one of the updates (I think it was the Android 6->7 upgrade update).
This leaves users not only unable to use any power banks, car chargers or 3rd party chargers to fast charge, but basically robbed users of ANY QC3.0 support (which the phone was advertised as being capable of). Even other ASUS QC-chargers (be they QC2.0 or 3.0, tried the Zenfone 2 charger unsuccessfully) don't enable fast charge, making it impossible to have another fast charger eg at work.
I thus have two questions:
Could QuickCharge be re-enabled somehow (eg. by rooting+app, custom ROM, or other means)? Would reverting to Android 6 do the trick, and if yes can this be done easily?
Thanks in advance.
