Hello guys how are you all doing?i am trying to get my nexus 7 2012 grouper work with autodroid 1.2.finally managed to install the rom.but I have a couple of issues
When I am driving,instead of the tablet charging via otg,it continues to drain battery.
When I turn the car off and the tablet goes to sleep mode,after 3/4 hours when I go back to the car and turn the car on,the tablet won’t boot up.i can hear my navigation voice but black screen.
And most of the time when I go back to the car after some few hours the tablet would be dead dead and have to take it out and charge it.
I like autodroid because of the option to have the media buttons on the Navbar,timurs rom don’t have that option it has only for volume (correct me if I’m wrong) for 2012 nexus 7.
What could be the course if the battery drain?i want to take the battery out and connect the tab to my car battery directly using the right dc converter but I am afraid it will also drain my car battery.any suggestions and help are welcome.thanks in advance for the answers

When I tried using the N 7 as a navigator, I found the battery going down as you describe. I found that in my case, the car's usb port was giving out a very low charge (less than 1A) which was not sufficient for the Tab's screen as well as the battery to be charged. Screen off the Tab and check if the car usb is charging it.
My solution was to use the 12V cigarette lighter port with a converter to give out atleast 1.5A.

Hello there thanks for the reply.i took the battery out and connected the tab to the car battery using dc-dc no battery mode.when I turn the tablet on it shows 100% but then it starts dropping.so even without the battery the percentage drops down.dont know why it’s dropping because the tablet is in no battery mode connected direct to the car battery.what could the issue be?could it be the battery’s pcb ?

How did you connect the N 7 to the car battery? Through the car usb which you connected directly to the car battery or through a converter/adapter? Either way, obviously the current sent to the N 7 is low. Measure the output and ensure that it is atleast 1.5A.

ok here's what I want to do.
Permanently integrate a nexus 7 in my car dashboard in the double din radio opening
Remove the battery from the nexus 7 and hardwire to always on power from the car battery
Hardwire the power button to a button installed in the dash
Dashmount a usb port connected via otg for hotswapping media
Hardwire a potentiometer into the dash for volume control
all of the above is fairly simple except for power supply, otg+charging is a possible solution but a car battery wired solution is far better so what i need is information on what the battery pins supply in terms voltage/amperage so i can create a 12v to direct power converter or a device that already does this. any help is appreciated TIA
bump, if someone knows i could really use this info

Can't you just use the USB port to charge it? it takes 5V, and 2A. With a car battery it should have enough amps, the voltage is what you'd need to regulate.
But if you really want to take out the battery instead...can't you just use a volt meter to see what the N7 draws from the battery? I'd guess it's 3.7v lithium ion but I'm not positive. I couldn't find the specs on google either..
As far as I have read there are some major difficulties getting otg+charging to work at the same time and I need the storage space provided by external storage. Having the car power source replacing the nexus 7 battery would eliminate that problem altogether.
I was hoping that someone here had known the voltages since I don't currently own or have access to a multimeter to test for myself. Knowing the voltages in advance would give me the opportunity to see what would be entailed financially to build the project and determine if its its financially acceptable to me, if the project isn't viable the money spent on the multimeter to do the tests would be wasted as it's not something I need for anything other than this particular project. So in the interest of trying to save $20 I figured I would ask here first and that there was a good chance that someone might have the information I needed.

oh ok..well have you taken a look at the battery? It should just be 3.7v, I don't think it would be too hard to find which pins it is. Maybe take a LED and test it across the pins?
Also, I have heard reports OTG + charging is working fine on CM10 with a patched kernel. you might want to check this thread: http://forum.xda-developers.com/showthread.php?t=1934722

I've been participating heavily in the arena of OTG + charging simultaneously, as well as using USB audio.
To answer the OP's question directly: I have demonstrated (to myself) that I can power down my Nexus 7, disconnect the battery connector, plug in my y-splitting OTG cable with power in one plug, and an unpowered USB hub in the other plug. [Plugged into the USB hub is a flash drive, USB DAC, and I'm sure a keyboard would also be an option.] Then I turn on my Nexus 7, and in the OS it shows the battery at 0%, but charging (obviously it's not actually charging without the battery present...).
I even booted up the Nexus 7 normally, with all the same stuff connected to USB, and then disconnected the battery connector... and the Nexus 7 remained on!
I've thought about integrating some sort of tactile switch that essentially disconnects the battery whenever the switch is depressed. So then part of the car mount could be a little protrusion that presses this switch whenever the tablet is inserted into the car mount. That way whenever the tablet is removed from the car mount, the battery will take over without removing power from the motherboard.

Am i understanding you correctly? If i unplug the battery, and just have the OTG cable plug into the charger, it would be able to power on and off and run just fine?

This was how it worked while the N7 was running Jelly Bean 4.1.2. I can't guarantee it would operate the same on 4.2.2.

Someone tried it on Reddit. Removed the battery and tried powering it on with only OEM charger. The screen just flickered. They were on 4.2.2
I am curious about removing the battery and hardwiring as well as I am gathering parts to put my Nexus 7 in my car dash. The problem w/ the OTG route - it gets pretty hot down here and I'm afraid the battery will have some long term issues (ie...could leak/explode). So, hardwiring it would be preferred.
Any ideas for hardwiring?
with the new nexus 7 coming out I am just going to mount the wireless charger behind the tablet dock, now I just hope otg is supported with the slimport on the new nexus 7
My Nexus 10 is rooted and on stock Kernel/ROM with locked bootloader.
I've just bought a TV tuner (Elgato EyeTV 3) that connects to the Micro-usb port - It works great - all of the freeview channels in my area within minutes of install.
I've also got a POGO charge cable. It charges my N10 OK using the official charger.
I had thought that using both together would increase battery life whilst using the tuner, but that's not what I've found, it makes almost no difference to battery life whether I use the POGO or not.
After 1 hour with POGO the battery fell 19% with the tuner on BBC 1, volume at 50%. (100% > 81%)
After 1 hour with NO POGO, the battery fell 20% with the tuner on BBC 1, volume at 50%. (100% > 80%).
I can't understand this as I've read on other threads that the POGO continues to charge even when using the microUSB port, based on my findings above this appears not to be the case.
I cannot find any options anywhere to ensure that the POGO continues to charge whilst the USB port is in use.
Am I missing something somewhere ?, do I need to use a different Kernel/Rom ?
Does anyone have any ideas that might clarify this for me ?
Try using the USB port but in another way (is not the TV tuner) w/ Pogo and see what the results are...

Hello!
I recently installed my Nexus 7 in my Honda Civic and I love it. However, I have some questions!
I am using Timurs USB rom and it works very well. I was using Fixed Installation mode with an OTG-Y cable and the tablet was going to sleep and waking up when the car was turned on or off just fine. However, the OTG-Y cable I was using was faulty and was not allowing the tablet to charge.
I now have it connected without the OTG-Y cable but Fixed Installation mode in Timurs USB rom requires an OTG-Y cable to work. I have tried to duplicate the same behaviour using tasker but I can't get the tablet to turn on reliably with the car. Sometimes it works, however it usually takes a few tries. From what I can tell this because of a battery state where it is powered but not charging.
I am wondering if there is a way I can use Fixed Installation mode in Timurs USB rom without an OTG-Y cable? or if thats not possible, maybe someone can provide some tips for making tasker reproduce the same behaviour?
Thanks!
Jarred
I can't answer your question, but do you have any pictures of it installed? I have a Honda civic 2013, but can't find a place to install it that I like.

I have instaled my N7 on Civic RS (7 gen). But removed bat - reason at -10C Nexus don't want to start =). About not charging your install - you need good wiring about 0.75 mm2 or 1mm2 copper wire and as short as u can from DC-DC converter to succes charge. And Fast charge settings on USBROM.

Thank you for the info, but this is not relevant to my question. My tablet is charging just fine.
Hi, I have recently installed my Nexus 7 (running CM10.2 on 4.3.1 and leanKernel) in the dashboard of my car. I installed a cigarette socket behind that dash that provides power to the device when the vehicle is running. When the vehicle turns on i have tasker set to lock the display on, start my music and torque. The problem I am having is when the N7 is one and receiving a charge the battery is still discharging (approx. .8%/h according to battery stats app). I have used 3 different charges, two which are 2.1A and the third is 150w dc 12v to 110v ac power inverter which i have used 2 different usb chargers in, but i am still seeing the battery discharge while I am using the tablet. i can rewire the cigarette socket so it is constantly charging the device but since I am not able to reach the power button on the tablet i dont know how ill be able to toggle the screen. i have tried to under-clock the cpu and gpu (currently have the device running on 1 core) but still havent seen an improvement. Any idea what i may be able to do to rectify the problem?
I was also going to try to upgrade the tablet to 4.4.2 but adb and fastboot cannot see the tablet anymore. i updated the usb drives and it was working perfectly fine up until a week ago so i am not sure what is happening.
Thanks for the help.

Hi, do you have a dcdc-usb? I know Who did your work (n7 in dash car) normaly have that, with a otg-y cable and normaly use USB ROM with Timur's kernel, which is a dedicated rom for car 's installation. Try to search info about that.
Unfortunatelly development is stopped to android 4.2 (the release before 4.3) But it' s very good rom.
If your installation is fixed, in the night u will lost about 1-2 %
Ps can you upload some photoes about your dash ?

I dont have a dcdc-usb as the power to the tablet is coming from 2.1A car charger or a 150w power inverter. i dont have a otg-y cable but i do have the means to easily install one if i ever need it. I never knew about USB rom and Timur's kernel. ill flash those asap and hopefully that will fix the battery drain. As for pictures i only have this one from when i first installed the the tablet but know i have my dashboard disassembled. hopefully this will hold you over for now .
Uhm i can say to u try the USB ROM,i haven't other idea
Ps nice work

Ted, you need to flash a kernel that supports fast charge and enable it. I have the same issue, after flashing a 4.4 rom I lost my fast charge and over the duration of a long drive the battery is discharged. Apps such as fanco kernel updater have the option to enable fastcharge, if the kernel supports it. Great setup BTW, I have mine mounted on the dash.

Hi ryar,
Thanks for the help. I've flashed a few different kernels that have fast charging enabled. The latest is Timur's kernel which says fast charging is enabled. Sadly my tablet is still discharging when its in use so I've decided I'm going to have it set to charge at all time and use a magnet to switch the screen on when I need it.

Are you trying to charge in host mode or just using the USB came that came with the nexus 7? I could help you solder power and volume to some switches so you can toggle screen on off that way? I bought a Samsung branded car charger and it works great for car charging. I made a y cable that you can turn host mode on and off with a switch. I could help talk you through it or do it for u if you buy the stuff its pretty cheap fairly simple to do if u have patients. Most of Those 2.1 amp dual port chargers only supply 1 amp to android devices, this could be your problem.

I am just charging the tablet straight up no host mode. ive used a variety of chargers: two different branded 2.1a chargers and both the stock nexus 7 wall charger and another tablet wall charger plugged into a 150w power inverter. Thank you for the offers! If its fairly simple to solder the power switch I would prefer to do that regardless of the discharging problem so that i can hard reset the tablet if i ever need to.

I've had my Nexus 7 "in my truck since last year. I at first had it sleep via Tasker, but I was having issues if I left my car for awhile. The batterywwould be low and if I didn't have long drives, I could never rechargeit to ssufficient battery fullness.
I changed my setup to have the tablet power on upon receiving AC ignitionpower using this adb command:
there is a Fastboot command that you can issue to the bootloader to make the tablet power on once plugged it.* “fastboot oem off-mode-charge 0” makes the unit power on the instant its connected to AC. “fastboot oem off-mode-charge 1” returns to normal state,* so fitting an external switch isn’t 100% necessary, but i decided i wanted one anyway. I’m using Tasker to switch the unit on and off* with the ignition, but having the external switch is a handy addition.

Then I have Tasker turn it off after minute not being used. I'm sure it's not good for the Nexus 7 to always be at 100% power, but I don't care about the batter health because I purchased this for my truck only.
My only concern now, is the safety of the battery in AZ summer heat. I don'twant it to explode, and iI'm wondering if the tablet will function with AC power only, then I could remove the battery and not worry about it.

How are about temperature there? How is your setup into truck? I mean n7 is into the Dash? Or You have some support? Anyway maybe your technical questions will be better answering on developer forum (If You have installed usb rom by timur)

The temperature gets to almost 120F (48.8C) in the summer, and that's outside the vehicle. I took a dremel to my dash and modified it to mount the nexus 7. It's clean and looks just about stock. I made a wooden box to the dimensions of double DIN, and put the mounting brackets on either side. I used sticky tape to mount a nexus 7 matte black case to the front of the box, so when I slide the box into the double din area it lines it up perfectly. Then I just snapped the dash back into place over the top of the Nexus 7. So, the tablet is basically built into my truck.

Okay so currently I use my genuine Samsung 2.0 MHL adapter for my car because I use the AppRadio 2 head unit in my car. I use the ARUnchained app with it and everything works great. However if I use a navigation app like Waze, my battery drains even though it states that it is charging. If i'm just listening to music without the phone constantly looking for my location then it will charge, but slowly. What really blows my mind is that if my phone is at 100% charge when I first plug it in and then use Waze, it will stay fully charged. I am using a Scosche car charger that puts out 2.4 amps per usb port. Also when I go into my battery settings it shows that the phone is being charged from (AC) instead of (USB). I have tried using various USB cables, MHL adapters, and even different car chargers(the one I currently use puts out the most power so I'm sticking with it). My question is, how can I get my phone to charge when using a battery draining app like Waze? It absolutely blows my mind that if you start with a full charge it will stay charged but you plug it in with anything less than 100% and it will drain.
I noticedon my phone that when navigation software being used my charger cannot keep up with battery drain untill i lover screen brightnes
