Have any of you daring devs figured out a way to tweak the Hero to accept the full speed charge from a USB??
Like how the old Touch Pro could be enabled to charge just as fast as on the wall charger (or very close to it)
Mod. edit: not dev related, moved to q&a

Hey all, I know this is a development area - but there is no General section for the G9... anyway...
I have an 80 Gen 9 original none hard drive none turbo which im installing in my car. So far it looks really really good - ill post a video when i finally get the facia on it. However I am struggling to keep up with the charge power wise.
I originally brought a tomtom microusb charger - which according to form puts out 1 amp (not enough). This works fine on my HTC evo 3d, but cant keep up with the power consumption of the 80. It does not show as a "slow" charger.
I then brought an adapter off ebay that has a 2.1a and a 1a port. These originally showed as slow, so I made an adapter cable shorting the data pins so it knows its a charger - but neither port can keep the thing powered, and both these and the tomtom 1 amp seem to discharge at the same speed while plugged in.
Im waiting on one from newmp3technology that is stated as a fast charger for the archos g9...
Now, on the device i have turned off bluetooth and wifi turned off, backlight always on at around 1/2 brightness, and i have it running an external laptop hard drive off the port on the back. GPS gets turned on when necassary - but doesnt really seem to negatively affect the power situation (which was kinda surpising). Ive set the maximum CPU usage at just 600mhz to try and kerb the power consumption also. While driving i have Poweramp continually playing, and have used copilot on and off for sat nav. It doesnt drop fast - but nor is it staying fully charged. Im sure I had no problems with this while on AC power in the house.
If anyone knows of a working fast charger, or has a suggestion I would be most greatful. I may between now and then test with an invertor and ac power supply. One other idea I have is to run the USB hard drive with a powered USB hub, to move the power consumption away from the device.
I believe there was one of those dual-usb chargers from Belkin, but knowing them the charger could be pretty expensive.
It also has one 2 amp and one 1 amp slot, though I have not tried it yet.
i have this
http://www.newmp3technology.com/francais/all-Archos-model-charger.htm
This is an other option www.newmp3technology.com/francais/archos-101-80-g9-cigar-split.htm
I also need to be able to run/ charge my 80G9 turbo on the road for long periods.
first the basics, the original Archos cable must be used to get max charge (its short and has the log like thing inline near tablet) every other cable/ wall charger I have tried will only give weak charge and if using tablet with other cable it may never charge at all *if you know this great, but everyday others have to find this out the slow or no charge way
now, that applies to the wall plug for sure but with a cigarette lighter usb adapter I'm not so sure you will get enough juice just with that cable. If there is a 12V adapter or complete plug and usb cord that gives full needed output, great. until its used and proven (real world) I don't know if it exist yet.
the best alternative may be to use a Power Inverter like one below, there are so many available I don't know if the ones with usb outlets would work, I have a cheap inverter I need to try but just with factory Archos wall plug & cable (I've used it in the past to power a hand grinder etc. with no problem, car battery stayed charged up even when vehicle was off)

I use the original Wall-Charger that came with the Tablet in conjunction with an HTC USB Cable that came with my HTC Desire.
It's charging as fast as with the original Archos USB Cable.
Even the small Wall-Charger from the Desire charges the Tablet very fast.
OK Ive received the so called fast charger from newmp3technology and it registers as a slow charger using the original supplied cable from archos. It took 17 days to arrive... not particularly happy with newmp3technology.
Anyway, I have found that the tomtom charger does actually charge the system while it is active - even though its only a 1 amp charger and the system requires 1.5 amp. Over about a week of driving for approx 1.5 - 2 hours a day the charge has risen from 0% to 19%. I had a USB extension (no more than 1 meter long) in line with the charger and that actually slowed the rate of charge.
The system is active the whole time - usually playing music through power amp, and sometimes using GPS via copilot. Ill test again to see that it can still maintain charge with GPS running. These devices really only require a small amount of power - I used to run a full computer in car and that pulled a bunch of power.
Here's the general section

No Probs - unfortunately that section did not exist when i created this thread...
Just got my S6 Edge from ATT here.
I've been hearing many accelerometer problems and some people say that it has to do with the quick/fast charging thing.
While everything's working with my phone, including the accelerometer and auto-rotation, I would like to just regularly charge my phone
if that makes any sense? (Just to be safe and sure)
Need some clarification I guess:
Is there a way to regularly charge the phone with just the default cable and charger?
Is there a way to disable the fast charging option?
Does it automatically start fast charging with the default wall charger?
Or is it the default usb cable that came in the box that enable the fast charging?
I guess I could just plug it in to my PC's USB slot but I think that would be slower in general than a wall charger.
So if anyone could shed some light on this, I would greatly appreciate it.
(P.S. I have not charged my phone at all since I got it a couple hours ago, waiting for it to drain completely and then charge)
So i love my nexus 6 because i can fully charge it in less than 2 hours with factory charger.
i also use a 28aw usb port and it makes it even faster with the factory adapter.
with all these new phones that are coming out (n5 2015) and supposedly they'd be using USB.C, does that mean that charge time will improve even more than quick charge 2.0 or would it stay the same? Is USB.C mostly faster data transfer or will it be "quick charge 3.0"?
Would someone explain it to me as i'm dying to find out how much faster phones will charge with USB.C, if any.
Thanks coming your way!
Far as I know USB-C is only the connection. Reversible. Don't have to figure out which end of cable to connect. To change charging rate is internal to device hardware and software.
that is one of the benefits. but from USB's website, it also increases speed from 3.0 to 3.1 drastically so i'm hoping to see some numbers!
It's going to depend on the power management chip that is in whatever the device is.
From my understanding it should also make charging and transferring data faster but not sure how much faster. It will probably be determined by the other hardware built into said device.
can't wait to see what it's going to be like.
universal is the way of the future.
I think how fast you can charge a battery depends on how much current the battery can effectively handle. I don't think it has much to do with the type of connector (usb-c) or the USB spec (3.1)
...except that we're already at the limit of micro-USB with tablets. It's why you have some manufacturers using proprietary charging connectors on their android tablets in order to get reasonable charge times for such massive batteries. The connector is very much a limiting factor after a point.
Whether we reach that point with current battery tech in phone-sized application is another issue.
As far as usb fast charge from a computer usb port it should make no difference. That is controlled by the kernel. For wall and QI charge need the upcoming Qualcom Fast Charge 3.0 that is in the new chips.
Hey folks,
you are reading right: For a certain reason* (if you care, pls scroll down) I need to "limit" the charging current to something like 500mA.
I am running stock rom (20c, rooted) but if there are solutions for custom roms / kernels I'd give it a try.
1st thought: The phone has an inbuilt "Thermal Protect" which can be disabled via hidden menu. It seems that the file (/sys/devices/platform/lge-battery/power_supply/battery/temp_control) only accepts the values "164" and "0". I'm looking for a way to actualy lower the temperature to trick the phone into thinking "wow, battery is too hot, I'll better charge slowly"
There are also a bunch of temp throttling files in /d/tegra_thermal, but as I unterstood they do only throttle the tegra chip which I don't want.
2nd thought: I've read articles about building special cables where the usb data ports are short wired, which then is interpreted by the phone as "charge only" and draws as much current as possible. I'd need it other way round and tried to just physically block the data ports but no success.
Why am I trying this? I bought a lamp for my bicycle which has a small (150mA) battery and a usb-out. The dynamo (generator) will charge the (inbuilt) battery like up to 40%, then the lamp will activate the usb port. The phone will then charge quickly (~1A) until the battery inside the lamp will go below the threshold, and the usb port will be deactivated.. and it starts all over. I'm ending up with a few hundred charging connections/disconnections a day of cycling with actually pretty few breaks. Thanks to snoozy it's not that bad.. but it still sucks.
Any ideas appreciated, hardware and software vise.
Regards, kugelz
I guess you mean 150mAh battery.
It's interesting how you say the phone gets about 1A during charging. How do you know that? One would think this kind of USB port (driven by a small battery and a dynamo) would provide max the standard 500mA (which is the slow charging you want).
Anyway, you could try the cheapest sh*tiest USB cable you can find, since the reason for being cheap is having a thin cable, and a thin cable means less current can flow.
Iodak
You are right, 150mAh is what I meant.
Someone created a diagramm for serveral similar devices (speed / power) and for speeds > 15km/h the current is about 800mA.
I flashed iodak kernel as it has the fast charge mod, but unfortunately in the latest ready-to-flash iodak kernel (v10) there is not the latest fast_charge mod included (where you can actually specify the current) but an older version where you can only switch it on or off
Hi,
I've got an old Samsung Galaxy s4 (i9506) and I would like to use it in my kitchen as multimedia center connected to a TV using a MHL cable. The problem is that phone detects it as USB so it charges only at 500 mA max, and it drains battery quicker.
I've been searching all around, and I didn't find any kernel that supports fast charge for USB ports for this phone... In fact I only found arter97 kernel, obviously not maintained for a long time...
So the question is... is there any easy way to enable fast charge in this phone? I know there's a c patch code available to add fast charge support to any kernel... and arter97 source code is also available, but I don't have enough skills to do it myself...
Ok. I was wrong... There's more kernels around than I though initially, and there's one ported from Note 3 with fast charge feature included:
https://forum.xda-developers.com/galaxy-s4/i9506-develop/kernel-krait-kernel-shv-e330s-k-t3548770
I post it just in case someone faces same doubt.
bye!
