Have a nexus 5 qi charger (googles own) and proclip setup in car. When using the nexus 6 with google maps for navigation, phone is losing charge even while on qi. This never happened on my previous nexus 5.
Is the power draw on the 6 with screen on much higher than what the charger puts out? If so, this would be extremely inconvenient since I use my phone for navigation every single day.

yup, the power output of the n6 could possibly be much more than whats going in, while using the wireless charging plugged in via a car.
I would say so, my nexus 5 would lose charge while navigating and charging in the car too
Can anyone point me to an app that would automatically dim the screen when phone is charging? I can save some juice that way in the car

you need a high power car charger to keep up with the charging. USB charging and wireless charging is not going to cut it.
there are turbo cigar port adapters that you can pick up. I have one.

Not plugging in a phone each time I get in the car. Defeats the entire point of qi charging for me. I'm going to automate screen dimming when charging and see if that gets me to stable power while navigating.
Anyone have a recommendation for an automatic app?

the stock nexus 6 wired wall charger can put in as much as 2500mV(what the n6 takes in). my nexus 5 takes in 1100mV max. where the heck are you going to find something thatll put in that sort of charge, from in a car? by default, you will get less power than my nexus 5 maximum intake. it may say AC while charging, but in reality you are just getting a fraction of a full charge. keep it plugged in, not wireless, and it might keep the charge, and not drop.

Most car chargers only output 1 Amp, car chargers are available that can output 2.4 Amp. Getting a more powerful charger could solve your problem. See Link http://thewirecutter.com/reviews/best-usb-car-charger/

Yes, I have a 2A cig lighter socket in the car already. I downloaded the "automateit" app and set a rule to dim screen to 50% when on charge. Otherwise, I like the screen at 100% all the time.
We'll see if that solves it.

I don't think you guys understand what I am saying.
Yes, I realize the N6 takes in a lot more mA's than previous phones.
Yes, I do know all about 2 amp cig lighter socket chargers.
Neither of those is relevant to my challenge. I use the phone for navigation extensively and I have a proclip dock + qi pad setup in both cars. I get in the car, and dock the phone. I am NOT going to get in the car and fiddle with plugging in wires. That's going backwards to 2005. That's going to a pre-Qi phone, which is a deal breaker for me. So, I either get the phone's power use while on Qi minimized to a point where its not draining while navigating, or I get another phone.
If I can't solve this, this is yet another major disappointment with the Nexus 6, for me. Frankly, I am regretting getting rid of my Nexus 5 so quick. The big screen on the Nexus 6 seemingly takes NUMEROUS sacrifices in usability with power draw being one of them.
my man...
Qi charging is SLOW! it you have gps running, which is a CONSTANT data connection, no trickle charge USB port power is going to keep up with that.
PERIOD.
keeping the screen off or muted/dimmed will not help if you have a CONSTANT data communication!
you need AC power to keep up with this type of battery discharge!!
same as if you are watching a video on your device. that is a lot of power being used (cpu, ram, screen, decode/encode file to watch, other things happening in the background) and no trickle USB port power can maintain a charge thats AHEAD of that.
qi charging is cool tech but its not yet ready to keep up with these types of demands.
you either use a turbo charger, high amp cigar port charger, in other words WIRES, to plug up the phone and keep it charged or stop using battery intensive applications.
Qi charging is not very efficient, there is no way you will maintain a positive charge while navigating, add to the heat issue, your phone could stop charging entirely. Qi is great for around the house or in the office but otherwise it can't really replace a physical connection.
I hear you guys. But I also know that my nexus 5 was used with a qi dock for navigation for well over a year. Thousands of miles. So I know its possible, maybe or maybe not with this phone. Well see.
I solved this. I am using the app called automateit and created two rules: when phone gets external power, I set the screen to 25% power and when external power is disconnected, I set it back to adaptive brightness. At 25% brightness, with navigation and use of an mp3 app and making calls, phone is stable on qi. In fact, it even charges at the rate of 1-2 additional percent each hour.

does anyone know of any tweak, app or utility that will disable the semi-regular notification telling me that "the usb port I am using does not have sufficient current to charge the device, please close some applications." It comes on whenever I am playing music and then switch over to my gps app. I'm never really in the car long enough and I think the normal warning when the battery gets low is sufficient enough without this thing popping up ever time i open a new app.
Any help is very appreciated. Its an ATT Pure with the last feb 16th energy rom, maxmanila, and sense 2.5
Thanks!
This warning message is to alert you to the fact that you are discharging the battery at a greater rate than you are charging.
It is not to tell you the battery is low although that is what would eventually happen rather more quickly than normal.
In effect the charge circuit is being overloaded and the battery capacity is being drawn down and depending on the usage, will result in increased heat generation which is bad for the circuits and the battery cell.
I gather you are using the device in the car. You should have a USB adapter that gives 1000mAh, at least, and if it's not then the associated circuits and also the wiring, could well be showing signs of damage from heat build up.
If the USB adapter is rated at anything less than 1000mAh I would suggest obtaining a more suitable one because it's not up to the job.
As for disabling the notification it will be a registry tweak if it's possible at all.
thanks for the help.
i checked the car charger,it is rated correctly. this also happens when its plugged into the pc usb port, or a powered hub. the only time it doesnt happen is when its connected to the htc ac adapter. when i am using it in the car, it still charges to full ( albeit slower than normal) even with the tom tom ap, music player, palringo, and bing open. I was aware that the battery will drain, i just want the only warning to be the low battery warning, which i have set to 20 percent, but even in the car, it doesnt ever get that low ( i do periodically discharge it to empty for battery maintenance reasons)

If you have a car charger rated at 1000mAh and it is exhibiting what you say then there is something wrong with it!
USB ports are rated at 500mAh nominal. That is to say the manufacturer of the equipment should make sure that one port will give that output.
It sometimes doesn't work that way and you get badly designed port power feeds across however many ports that you have and if you have more than one in use then the current drops of accordingly. Then it struggles to charge your phone.
Even powered hubs can suffer this way.
When you use a wall charger that all changes and the whole thing works efficiently.
Having your phone under stress like this in your car is not a good thing and neither is periodic discharge. It's just not necessary.
Could you please give me an advice? I'm using my tom-tom charger for my td2 in the car. It says 2A for output while the td2 original wall charger says 1A. Do you reckon is there any problem? many thanks.
If the car charger at 2Ah does not have a "shut down" circuit, or the charging system in the phone does not, then you will, in short order, smoke the battery.
Ok, txs jdwilson. You mean "shut down" circuit as a way the charger prevents the energy pass to the phone when the baterry if full but allows it when more energy is needed? By the way, now i've notice that my tom-tom says input 1A! So, the charger as the "shut down" circuit or tom-tom as in it, or i will have the same problem on my tom-tom, although the charger is the tom-tom original one. Thanks
Quick question. If you leave your phone plugged in and its fully charged and your using it, is the phone just leeching off the charger for power or is the charger pushing out small bursts of power to the battery. The context of my question is i'm starting to use webtop alot and I leave my phone on all day plugged in. Is continuing this behavior going to impact my battery or does the phone just leech directly off the charger without using the battery?
It's fine to leave it plugged in all the time. The phone has a "smart circuit" that use what is called trickle charge to just continually top off the battery as it drops below full charge. The phone is designed such that it doesn't receive power directly from the charger or USB cable, unless the +5v DC current is on pin 1 like a factory flash cable.
Bottom line is there is no damage or shortening of the life of the battery to leave it charging all the time while in the dock or any other means and Li Ion batteries no not have memory problems.
On a related note, is there any damage in using low-power chargers?
I have an external solar-powered battery charger that also supports USB-out, and I find that it doesn't put out enough power to really charge the battery, but it can keep the battery at its current charge level (whenever it is plugged in) for the equivalent of one charge (so the phone could theoretically last 2ish days).
I'm wondering whether this is constantly charging/discharging the battery (bad thing), or just providing enough power to run the phone (good thing).
I've also seen a similar behavior when charging over USB. If I'm using the phone a lot, sometimes a usb port doesn't supply enough juice to charge the phone.
I also saw this in some (rarer) cases with my OG Droid, but I didn't pay it much mind because I had 3 batteries for that thing and you could pick them up for a few dollars off of Amazon.com.
Thanks!

To my knowledge, there is no reason a low power charger should present any problem, but charging from the USB on a PC is limited to 350mA and will definitely not push enough current to charge the phone while it is under heavy use like Mobile Hotspot tethering with LTE or even 3g.
The standard wall charger is 850mA and even that can sometimes only keep up or charge very slowly under heavy load.
USB spec is [email protected] not 350mA. But yes, a dedicated charger probably will charge faster. Some may go as high as 1A output...

I have a aftermaket car charger that does not show "slow charging" but when I am using google maps, it will slowly drain the battery, but if I use a power inverter and use the ac adaptor and cable that came with the phone, it charges faster than the screen, gps, and maps can use it up.
does anyone know of a car charger that is up to this challange?

Because most likely it is a 800ma-1amp charger. Get a 2 or more amp charger... very extensive car charger thread here....
My father bought one of these for his G2:
http://www.amazon.com/Vehicle-Charger-Dual-Output-Universal/dp/B00C9D5EJI
I'm not sure where he ordered it from.
I tried it out on my G2 with Waze running, screen on, and GPS running. No slow charge indicator. I left work with the battery at 69%, drove for a little over 20 minutes, and ended up at 81%. That's a nice fast charge with all of that running. I'll try it sometime with bluetooth and pandora on as well, but I imagine it'll keep up.
I purchased one of these.

Make sure you have a micro usb cable that can handle it as well. My old cable had the "slow charging" notification but once I switched it out for the one that came with the phone, it went away.
hope that helps.
I just buy a car charger for iPad and it works perfectly with 2.1A max. Screen on 100% light, battery turn 60% to 80% on 40min.
I have built a Nexus 7 into my car and I have a small issue.
I need a tasker profile:
When I turn the car on, the screen turns on and music plays.
When i turn the car off, the music stops and the screen turns off. (along with other stuff)
I have created a "test" version of all this so when I connect a power cable (i.e when charging) it turns the screen on and plays music.
When I disconnect the USB (i.e. stops charging) the screen goes off, music stops, bluetooth off etc and all this works fine.
However, the USB will always be connected with power coming through so I cannot use this option. I need another way to detect if the car is on and when it turns off so I can run the correct tasks.
One option i thought of is buy a wireless charger and build it into the car. When my phone is placed on the charger, send a text message to the tablet to turn it on, and when i turn the car off the charging will stop, then the phone will send a text to the tablet to turn the screen off etc.
However after purchasing the wireless charger, i realised everytime i get a call or take my phone of the charger for whatever reason, the screen will go off and music will stop, so this isnt an option either.
So the question is, what can i do so tasker can detect that the car is on or off so the nexus can perform the tasks?
Hope that makes sense

You do realize that you really have two problems, right? The Nexus 7 will not know when the car is started, or stopped. Unless you can disconnect the power, manually etc.. If you can do that, you can send a command in fastboot to force the N7 to power up when power is connected, otherwise you'd have to boot it up manually.
You could unplug the USB charger.. Or have the tablet turn off after N hours of inactivity, although how do you detect "new" activity if there's no change when the car is started.
If your car has bluetooth, you could detect that as the "turn off" task perhaps, but turning on is probably your bigger issue.
Will the wireless charger idea work?

No idea what you mean by wireless charger (2012 model has no wireless charging), or how you'd control it with the phone. And unless your tablet is a 3g one, I don't know how you'd directly communicate with it either.
I just put my phone back to stock so I had to uninstall Tasker, however your tablet does not pull power once the car is off correct? I had a power based one as well, I remember testing it with a surge protector. I could leave the USB connected but flip the surge protector on and off (to mimic power to the phone being halted). To my knowledge when the car is off your USB shouldn't be drawing power therefore you could run the profile off that. Export the profile and post here. I'd like to help test it.

My last four cars (current and previous of wife and my cars) the lighter plug stays powered when the engine is off.
I think it's getting increasingly common for the plugs to stay powered. So there's no way for the tablet to know the car is off unless the car has bluetooth and you can look for that.

I have actually found the exact opposite to me true. My wife's 2014 Pilot goes off as well as my 2012 Veloster whereas my 2001 Sable and her 2007 Passat left them on. I'm not sure if you can resolve your issue then. I'll keep looking into it. You could trigger it based on speed I think

I suppose that could work.. Find out the speed for several periods in a row, if it's zero, assume it's time to shut down. But that'd mean it's playing music etc during that period etc.
IMO bluetooth, or a plug he can turn off, is really the only way if his USB is powered up all of the time.
Also remember, he has no way to know when to power UP either. I still maintain that's the bigger problem, especially if it's a fixed install and he can't poke the power button
At the moment, its connected so when the car turns on, the USB is powered up and when the car turns off, the power in the USB stops. So at the moment, my tasker profile works on "when charging" do Task A, when not charging do Task B. And it all works fine at the moment.
However I am having issues with charging, (The device is not charging fast enough when turned on and the battery drains over a couple of days) so i planned to keep it always charging, so the power in the USB will always be there regardless of if the car is on or off. So i cant use the "when charging" on tasker anymore. So i needed a new way to it to figure out when i got in the car.
Here are my ideas:
1. Have a wireless charger in my car for my phone. (Not the tablet). When i get in the car, i could put my phone on the charger, have the phone send a text to the tablet to turn it on. When i remove the phone from the charger, send a text to the tablet to turn it off. Simples
2. Connect a wifi router in the boot or something and have it start up only when the car starts, and turn off with the car. It doesn't have to be connected to the internet, it just needs to power up. Then i can do a 'When wifi near' on tasker to see if the car is off or on, and turn the screen off accordingly.
3. Connect the tablet to my phones bluetooth. Whenever i get in the car, they will connect and the tablet will power on. when i leave the car, it will power off. (Not the best option since it will stay on even if i am near the car)
4. Similar to option 1, but have a nfc sticker in the car. when i swipe my phone on it, it communicates with the tablet and turns it on, n then off when required. but i dont want to do this since i know i am going to forget to turn it off one day.
I don't really want to do the speed option, since i want it to turn on as soon as i enter the car, not when i start driving, and i want to be able to park up and use it when i need to put an addess in the sat nav etc.

If your charger isn't charging fast enough, you're using a crappy charger or one that isn't designed for Android. If your car has a built-in USB port, those are usually super slow, maybe 500mA, most less.
Anyway, glad to hear that your power follows the car state, that makes it all simple.

I've tried about 20 different chargers, up to 2.5amps. The problem isnt the charger. The problem is i dont drive the car long enough to give it time to charge. So if i drive the car for about half an hour a day, for the other 23.5 hours, its on standby. so the battery is always going to go less. So thats why I plan to connect the charger directly to the battery so it will always be charging.

Oh, I thought you had the tablet turning off when the car went off. If I were you, I'd set up a profile that turns off the tablet if it hasn't had power in a few hours, pretty simple to do. On Power, set a time var, every so often check that time var to see if it exceeds your threshold, and power down if so.
If you don't have much installed, it should be a fairly quick power-up, especially the plug goes hot when you start the car.
BTW I hope you're considering cold and heat if you're leaving the tablet in the car. Leaving it in the heat all summer will will the battery.
You can use Timur's kernel, it senses power to turn N7 on or deep sleep it.
Also charges N7 while using OTG.
It;s designed for car install.

I agree, you need to get at least a 2A charger for your car. My wife would watch Netflix on long drives and my car USB port or the normal USB charger I got for the cigarette lighter worked until I up'd it to a 2A charger. I can have screen on for hours while streaming video and still fully charge the tablet in a reasonable amount of time.
do rooted/custom roms enable this or is this a hardware limitation? I understand its a temperature related issue. I am not saying fast charge while using overlclocked cpu and playing games. It just seems a tad annyoing that i cant charge my phone while driving in my car and navigating at the same time. (it will charge but only so very slowly....)
i am talking about the "adaptive fast charge" which really only fats charges when the screen is off or in AOD (always on display)
When you, lets say, have google maps open while driving the "fast charging indication is actually lying to you. It will only draw about 5 Watts there.

I see someone wants to recreate a newer Note 7. I don't think is is a hardware limitation, of the physical phone or the stock charger, but the (stability of the) battery itself. Playing a game at full brightness would require adaptive fast charging to generate too much heat in the battery itself to compensate for the rapid battery drain, and maxing out the factory charging cable to replenish what was lost during current use and charge the phone in the same quick time you are accustomed to (with the screen off).
You are really asking another Note 7 disaster

haha not quite. i think you are confusing some concepts here. The net energy / charge arriving at the battery is actually less when the device would be under full load because the device itself uses a portion of the energy supplied by the charger... or am i missing something?
I think the gpu/cpu/screen heat in combination with charging is what the issue was on the Note 7. The battery itself can, as it might be obvious, easily be charged with ~15w. I believe the smart solution here would be to simply reduce/throttle charging with relation to CPU/battery temp.
I can tell you that when in a holder in an air conditioned car using google maps the battery will be fine with quick charge unless there is some weird coupling between two ICs.
Any decent quality USB cable will not be a limiting factor. 2 Amps @ 5V or 9V is really not a problem/
My measurements with the factory cable and charger at about 85% battery were around 1 Amp @ 5 Volt with screen ON and about 1.67 Amps @ 9Volts with screen Off or AOD on.
anyways. really only wondering if custom ROMS support this is or not. having my phone quick charge in my car while navigating is very important to me.
I think Samsung just played it very very very Safe after the Disaster. Limiting current and battery size that a guy who quick charges his phone in a Sauna can play candycrush on max brightness in performance mode....

Samsung smartly chose to avoid the issue altogether.
Heat dissipation will be that issue to contend with in my opinion. My phone's charger only does 18Watts on a good day (screen-off) in an airconditioned room (measured by a USB multimeter). There needs to be adequate overhead left in the thin stock cable that is shipped with these phones (which isn't even USB 3.0).
I believe that this maybe an safety feature built in by Samsung in the wake of the Note 7 battery issue. There may not be a work around for it.
