[Q] Does leaving USB debugging enabled negatively affect battery life? - Google Pixel 2 XL Questions & Answers

I prefer to leave it enabled since it gives me a little parachute if the device has issues upon bootup. Plus it's easy to send commands via ADB.
Just curious if leaving this enabled drains the battery more? For example, on my Gear S3 watch, it's recommended to leave debugging disabled since not only is it a "security risk" according to them but it also can negatively affect the battery.

cant say for sure, but Ive never turned it off, never had any issues with regards to battery because of it.

Never heard anything like this... Mine is on all the time for evry device I've had.

same as above...have used usb debugging since...forever...

Great, thanks for the info!

Just like OEM unlocking...always leave it on! :good:

I kinda think of it as a wall switch on a ceiling fan. you can flip the switch, but no power should be used unless you pull the fan chain. it's just a path you are allowing access to underlying stuff, I don't see any reason having it on would drain anything more than not being enabled.
you will still get that prompt for allowing a new device to perform actions anyway. it's best to leave it enabled, and have it already familiar with a primary device with platform tools installed

Great analogy!

It is a security risk.
Of course, everything has a downside, and for USB Debugging, it’s security. Basically, leaving USB debugging enabled keeps the device exposed when it’s plugged in over USB. Under most circumstances, this isn’t a problem—if you’re plugging the phone into your personal computer or you have the intention of using the debugging bridge, then it makes sense to leave it enabled all the time. The problem comes into play if you need to plug your phone into an unfamiliar USB port—like a public charging station. In theory, if someone had access to the charging station, they could use USB debugging to effectively steal private information from the device, or push some sort of malware onto it.

Back with Secure Settings, I had phones set to enable USB debugging while connected to my home wifi SSID and disable when not connected. I can see no way it drains battery, since it is a permission only and not an active app.

[Q] Franco kernel and forcing fast charging...

Running Winnner00 CM9 + Franco kernel (tried nightly 160 and stable M3)
Using Franco's app I am unable to enable force fast charging. The checkbox in Settings seems to be ignored. Tried both nightly and stable kernels, reboots, etc. It does work from command line, so I think the issue is in the app itself. Am I missing something here?
Any suggestions?
Does CM9 have the option built in? I know AOKP does. I leave them both fc options enabled (rom & kernel) because I charge my phone in the car waaay more often then I plug it up to the comp. If CM9 has an option for it enable it there.

did you unplug before turning it on? you cant be plugged in while enabling fast charge.
Also, try updating your superuser (even if it says it is up to date). Just a thought as I've read this can cause issues.
Afaik, CM doesnt support fastcharge.

Yeah, basically it is a combination of a few things - one is that even though it says it is enabled at boot time, it is not. You have to turn it off and back on. The second is what you mentioned, you have to unplug it and plug it back in if you turned it on while plugged in.
I ended up using a plug-in for Tasker to manage it, though it is wierdly hard to GET the current state (how hard is it to read a file, apparently hard) from Tasker, though setting state works.

You can check out Secure Settings plugin (sorry, can't post links yet, but search it) - it is great for a LOT of things including this (its under Custom ROM options)

"THANK YOU" (For ur thanks meter)
But, on a serious note, i got the solution for the problem already..
For others out there seeking the solution to the problem, the trick is to unplug and then again plugin the USB cable after you enable the fast charge..
And then in battery stats it should show charging(AC) instead of charging(USB)

Sorry, I missed that this was the issue you were trying to solve. Yeah, when you switch the charging mode, it only takes effect after you next plug in. It will not change your current connection - which can be especially tricky if you reboot while plugged in.
I wanted it to be on by default since I hardly ever use USB for data. I would love to have the ability to have it come up enabled and to disable it, but that does not seem to be how it works - which, I guess, makes sense as you would loose any ability to debug in case of emergency, as in fast charge mode all data communication over USB is off.

If you keep the fast charge option enabled, it would always be on by default, (the way YOU need it), and when ever u want to use the USB, turn it off..
There are plenty of apps on google play which support simple toggle between fast charge on/off.. many of them have widgets too.. which makes it more than easy, just a tap away..

Not entirely true - first of all for this to stay on you have to have Franco's app (or another app that turns it on at boot time) to auto-turn it on on boot - it does NOT keep state across reboots. At the time of the original posting in this thread, the Franco's app did NOT work for this, so you had to manually go into it and turn it off and back on again before it worked - so I automated this via Tasker. Just tested, seems like it is working now (although it takes a while after boot before the setting is applied, Tasker/Secure Settings route is MUCH faster). Secondly, if you boot up with the USB cable in, it will ALWAYS boot into USB mode because of what I said before. (Unplugging it and plugging back in once it is fully booted and fast charge is on, will turn then register it as AC).
But yes, there are a number of other routes and apps to do this.

I said that because mine stays on across reboots..
If your option turns off, Tasker is no doubt the next option..
And regarding booting with USB cable plugged in, i already mentioned in a previous post that you will have to unplug and plug in the USB cable again to enter into fast charge mode with stats as Charging(AC)

USB Issue?

Hopefully you guys can help me out. I'm suddenly having issues with my phone not being detected by my PCs when it is connected via USB.
When i plug my phone into my PC, i receive the error message: "UBS Device not Recognized One of the USB devices attached to this computer has malfunctioned, and windowes does not recognize it." from my Windows XP PC. My Windows 7 PC is unable to recognize the device plugged in.
The strange thing is that even though my phone is not being recognized by the PCs, the phone will still charge.
The phone is not in USB Debugging Mode, and I've gone ahead and flashed 2 separate Kernals on my phone, but i still am having this issue. I have tested this out with 3 USB cables, on 3 separate computers (Work (win xp), Home (win7), and friends(win7)).
2 Days ago the USB worked fine for me as i was able to flash Franco Kernal and JB onto my Gnex, but suddenly it's not being recognized by my computer anymore.
Stumped.....Hoping that this isn't a hardware issue and something that i can fix without having any downtime away from my phone.
Any thoughts?
Try other USB port and other USB cable.
Sounds like you're missing some drivers... Remove the device completely in Device Manager & plug it again. For MTP, Windows 7 should find the drivers online by itself. If you need fastboot access, you'll have to download the seperate drivers for that. I'd recommend the GNex Toolkit in that case since it comes with the drivers included (you'll still need to install them of course )

Thx for the reply,
Yes, I have been using the GNEX tool kit, though not the 7.3 version that was released today. The 7.2 version was being used at home and on my work PC. I usually install the drivers from the toolkit then plug my phone in when done. The drivers have been recognizing my phone but not since 2 days go.
I'm currently trying to find the MTP checkbox in the phone Settings to double check if it's checked, but im having problems locating it.

Ah yes, that is where it was hiding....But unfortunately the checkbox is checked.
This seems like a hardware issue, but I'm not certain since the phone still recharges when plugged in

Could be... Charging doesn't necessary have anything to do with data transfer AFAIK... Do you see something in the Device Manager when you plug it? You might have to right click & do a re-scan to force detection.

Device Managers shows "Samsung Galaxy Nexus ADB Interface". The drivers look to be installed.
Also another odd thing, is that after i charge my phone and unplug it from my PC, it will continue to show that it is charging on the lock screen and in the top right corner of my phone. However if i go into Settings ---> about phone. It shows Battery Status : Not Charging.

You get that when the phone is running normally? I think for me that one only shows up when I put it in bootloader mode. In MTP mode it's just a media device like any other AFAIK... I'll check tomorrow when I'm back on my Windows laptop to be sure . Have you tried putting it in PTP mode? If so do you see the device as a camera or is it the same issue?

And get your drivers from Samsung and Android sdk. Qbking77 has a YouTube video on how to set it up.

Basically the way the Nexus One talked to other systems through USB is completely different from the way the Galaxy Nexus does. The GN uses a new protocol called MTP. Your car stereo probably can't read the files on your phone because it doesn't have MTP support.
Phantom Charging Issue
So I've gone ahead and Fiddled around with my phone for the past day trying to fix my USB issue, and I've discovered that this issue may not be due to USB issues.
Throughout the day when i was playing around and trying to fix my USB recognizing issue, it miraculously started working again. Now I am able to connect to my PCs and transfer the desired files.
Upon this issue being resolved, i noticed that periodically the screen would turn on, on it's own while being off in the locked state. I observed this issue to see what may be causing this, and it is turning on due to my phone thinking that i plugged my micro USB cable in to charge it. The charging indicator on the batter flips on, and even the USB Debugger / MTP Notification is present in the notification drawer.
Apparently this is a known issue with the Battery or charging port with Gnex's. (See below the 2 youtube clips for more details for problem/fix.)

I believe my warranty is void since this phone was purchased in a different country and has had the bootload locked/unlocked a million times. Anyone else have this problem that they have been able to fix manually? Or am I going to have to cross my fingers, ship my phone to get it fixed, and hope the post man doesn't f**k up?

[Q] Why won't my Galaxy Nexus power on?

I have a Samsung Galaxy Nexus. It is had some water damage in the past (making it near impossible to get repaired under warranty) and that has caused it to act funny. Funny = Powering off at random times and rebooting itself/causing the buttons to act silly. Recently it did the thing where it powered off and now it won't come back on. I know the power button still works and it is charging because when I plug it in the charging symbol pops up when I press the power button. However it won't power on. I plug it in to my laptop and it charges but my laptop does not recognize it is plugged in. Is there any sort of program I can download that will allow me to get into my phone or anything I can do? Also I have tried the Power and Volume buttons to try and power it into Bootloader mode but that does not work either. Neither does pulling the battery or putting a different battery in or using a different charger.
Isnt it clear it is dead? Electric stuff+water=death. (Physics 101)

Why are you people so mean? I am looking for help, really just a program that would allow me to plug my dead phone into the computer (since it indicates it is charging) and allows me to get files off of it. That would be nice.

Hey man,
I'm not sure if your gnex is salvageable, but if when you plug it into your laptop it indicates charging perhaps you may be able to get to your data. First question...do you have usb debugging enabled in settings? We have to get your laptop to recognize the phone as a drive,then try to grab the files. Tell me more about what happens when you connect it. We aren't all mean, some here just forget how it was when they had nothing but questions and no answers. Most in the forums are very helpful, regardless of experience level.

Thanks for your civil post, I will try my best to inform you more on what my phone is doing.
When I plug it into the laptop it does indicate it is charging but that is the only sign of life I can get out of it. After reading a little bit more on the issue I figure might be the power button that is the issue since it is running JellyBean. One solution that I have tried that has yielded interesting results is plugging the phone into the laptop via USB without the battery in the phone. My computer then makes the "beeping" sound like it is connecting to it and then "beeps" again like it can't connect.
I can't post a link but if you google katzz ifixit then you can go to the website I went to that described the issue and gave the solution I just described. Katzz is the name of the user who posted the solution.
I'm pretty sure I have USB debugging enabled in the settings because before my phone stopped responding I plugged it into the computer a lot to transfer files.
Is there any sort of program that would allow me to turn on my phone from my computer even though I can't seem to get my computer to recognize my phone?

Device can no longer see computers, need some help figuring things out.

Ok, first off I chose Sprint because I believe that Boost Mobile is on the sprint network, but my phone doesn't specifically say sprint on it or anything, so I had no clue which of these device boards to post into. This is the exact page I got it on, if that helps. [link deleted - paranoid forum rules] - I will post specs of the device in a minute.
Alright, the issue with my phone, is that after I used a car charger 2 months after I got my phone, it suddenly stopped being able to connect to ANY computer ever again. I suspected it was PDA net at first cause that was the newest change I had done to my phone. So, a few days later, I could find now way whatsoever to fix it, and had to factory reset. This fixed my phone just fine.
Two months later, I was fed up with having battery issues all the time, this phone drains battery faster than my laptop, and its battery is 3.8 years old! I got an external battery that holds 20,000 mAh/74 Wh (Practically the same as my laptop battery too. ) that is from the LimeFuel company. I know that before I used it, my phone worked with my laptop just fine. I don't plug my phone in to my laptop all that often, especially now that I have a battery to use with it. However, I download large files on my phone with 4G to put onto my laptop because my home net is crappy, so a week after, I noticed that my phone lost the ability to communicate with computers, again. I then realized, it had to be the connections. The first time it happened was when I used a car charger, the second time, an external battery. Each time, my phone suddenly inexplicably lost the ability to communicate with a computer ever again. It can only see devices as a power source, nothing more. There's no missing software or drivers, it just doesn't register as anything to my computer. Like a power toggle so it can't tell the computer "Hey, I'm a device that you can transfer data with".
One more note; The first time this happened, I had activated developer options but had them turned off. I mean that I used USB Debugging mode once and turned all of that off. The second time, I hadn't even unhid the option yet, unhid after my phone broke again to try and fix but nope.
I did research on trying to fix it, without factory reset because a factory reset is USELESS, if it's going to happen every single time I use anything but the wall to charge it, right?
There was a topic online claiming that there is a menu under "Storage" in the settings. There isn't. It was a big fat lie. Or Android devs deleted it.
There was another topic, claiming that USB settings would be under some wireless and networks area. Nope.
Now, I remember that when my device would connect to the computer, it would let me change it from MTP to PTP, but after this happened, nothing. It doesn't even pop up anymore, nor does it ask. There is no where in the phone that these options even exist at all. It's like Android devs deleted access to these options for no reason whatsoever.
Another bit in that topic mentioned ‘USB Mass Storage’, which also doesn't exist. Here's the topic with everything I tried, if I'm allowed to give links at all. If not, well not my fault. Topics used to try and diagnose and fix issues, but failed;

Why does it stop accepting data from computers after I use a car charger or an external battery pack?
Why would Google/Android devs choose to intentionally break your phone like this?
Code:
Hardware: L710T.03
Software: L710TVPU0AOA3
Model: SPH-LT10T
Android 4.4.2
Kernal: 3.4.0-1683363 (Ask if need more)
Build: KOT49H.L710TVPU0AOA3
Ask of need more.

First off, after the factory reset and everything worked did you reinstall the pdanet?
Second, 20,000mah battery? Holy cow im jealous!
Forgive me if you have already tried these things but this is what i would do...
Did you reenable developer options and reenable adb debugging?
Did you uninstall and reinstall your phone drivers?
Is there an updated phone driver?
Have you tried a different usb cord?
Is there excess dirt or dust in usb charge port on your phone?
Does your usb charge port even work anymore or do you just charge external battery on wall?
Have you tried a different usb port on the computer?
Have you tried on another computer?
Have you tried updating computer drivers?
Have you enabled a fast charge tweak like on a kernel tweak app?
If none of these questions fix it then a workaround is downloading app called airdroid. You can wirelessly transfer files from phone to computer and back again without usb cord.
Let me know what worked please! Good luck!

1. No, I never touched PDA net again.
2. Too bad forum rules say I can't be friendly and give you the link to it.
3. Read the topic you quoted. I did, only after my phone broke again. Except it's not adb debugging, it's USB debugging. Doesn't work, because the phone can't communicate with a computer anymore.
4. 5. 11. Yes I reinstalled drivers and no there were no updates.
6. 7. Nothing's wrong with the cable. I did try with others.
8. What does that even mean? Yes my phone's port works. Nothing's wrong with any hardware.
9. 10. I've tried different ports and different computers.
12. Can't, phone isn't rooted.
13. I'm not using this. My phone is not there for Google/Android to tell me I'm not allowed to use my USB port ever again. I'm also not going to wait 4 hours for a 4 GB file to transfer via my router to my computer nor am I installing some app software to my computer just to have wireless transfer. This is not a work around. This is an "Oh well, it's broken, guess you can't ever use USB ports again for data access!"
note; I tried all of these (except 12/13) before I ever came here looking for help.
2. I will google it
3. I didnt realize toggle to turn on usb debugging didnt work sorry. I just know it needs to be on for the computer to see the phone. This seems to be an area of problem possibly.
8. Lol! What i meant was did the area where u insert charger function properly. Only reason i asked is because some of those batteries charge on wall unit made specifically to charge the battery only not with charge.
12. Doesnt require root for basic settings like changing governor usually. Only to overclock/undervolt, etc.
13. Great answer! But i meant as a temporary fix until someone more experienced with this issue helps you.
I also figured listing all those things would help other people see what you had and hadnt tried before asking you next time. Wish i couldve helped more. Good luck

2. amazon dot com /External-20000mAh-Limefuel-LP200X-Flashlight/dp/B00OHZVN5U/ - It let me charge my phone 7-8 times fully before it was empty. Automatically stops when your phone is full.
3. USB debugging doesn't need to be on in order for a phone to communicate with a computer. This is only if you want to debug apps or use other developer tools. File transfer works just fine without it.
8. I still don't understand what you mean. My phone is not broken in any way. Nor is my battery. My external battery charges off any USB input, my phone charges off any USB input. My phone just can't communicate data wise between devices anymore via USB.
12. Fast charge isn't going to fix my phone. Unless it disables data communication, then I need to turn it off. All "kernal tweak apps" appear to require root. The top 5 google searches shown this.
3. Wasnt sure. Ive always had it on
8. Some aftermarket batteries dont charge while in phone hooked up to charger. They come out of phone and into specialized charger for battery only not phone with it, so that it can charge the larger battery in a matter ofan hour or so is what i have been trying to say. But its obvious thats not the case for you now since i asked and clarified. If this was the case one might not know that the small usb port on their phone needed cleaning to make a good connection because they literally dont use it to charge their phone. They charge their phone with external battery charger. You see?
12. On my custom rom and on my trickstermod app it does say fast charge disables data communication and that you have to turn it off for computer to recognize phone again. This fast charge mode only works when connected to computer not wall charger it says
Wish i could be more help but im out of ideas. Good luck
Update to the current situation.
My phone is somehow, repaired. But I have no clue why. I did several things today, just screwing around while I backed up my stuff to the SD card. One of them could have fixed it, or my phone is magic and self repairs after a while. Lets list everything I can remember that I did.
1. I typed in *#9900# in my dialing app. Toggled an option called "Low battery dump" to "on".
2. I deleted a whole bunch of files, including hidden files on the internal storage. Probably screwed up my apps but, whatever, it works now.
3. I pulled the SD card out.
Shortly after all these things, I plugged it in for power, and it finally, got my computer to see it as an MTP device again. No clue which of these succeeded. I'm going to wait a small bit before I test the things that tend to break it.
The magic option, is because I tried to root, it broke, stuck in download mode with some error about firmware. For 4 hours it was stuck like this, I tried everything I could think of, which wasn't much, tried installing the ROM back too, after wasting 2 gigs of bandwidth downloading it only to get an error before it even started the install. Phone was still rebooting in download mode error screen. Left it sit there off for like a minute and it just turns it's self back on, flickers a few times and the logo pops up and the device pops on like nothing had ever happened to it. I'm so confused. :/ At least everything's back to normal. Now add a good confusion post icon below so I can click it and post. :|

this was your problem remember? fast charge does disable data communication.

Except, I don't have a fast charge option anywhere. I can't toggle fast charge. My phone is unrooted and locked and such. If plugging in a device like a battery or a car charger, toggles this option and the OS developers deleted access to toggle this option, it is an OS bug and a critical issue in the device that needs to be fixed. I don't know what fixed it, but I'm assuming it was the low battery dump, and that doesn't appear to have anything to do with fast charge and it was a hidden secret option in the system.

The way u said it i misunderstood i thought u did have it on. Its not an option on all roms though. Mine has it and i tried it and couldnt see files thru usb until i toggled it off so it was just an idea. I dont know the effects of the low battery dump off top of my head but i will remember that if i hear someone else with same problem. Glad its fixed now

touch screen is non-responsive and computer does not recognize device

The touchscreen on my 2013N7 fizzled out earlier. Responsiveness has been on and off for the day - for a few hours it would improve after I press on a certain spot on the back of the device, but after that it has gone entirely. I've rebooted several times and there is no response.
I'm trying to use android control (http://forum.xda-developers.com/showthread.php?t=2786395) to just access it and get my data off of it, but when I plug it into a PC, the PC doesn't recognize that there is a device plugged in at all, even though it'll still charge the N7. It's completely missing from the device management list; adb shell can't find devices plugged in. I've looked around for possible fixes, but all of the ones mentioned require being able to access the tablet.
I'm at a bit of a loss here - is there a way to get the N7 to show up on the device list, or an alternate way to pull data off of it?

The spot corresponds to the plug (att) and now it is time to unlock, reseat the cable and relock it as all of the problems relate to poor contact of the cable.
Same issue here,I am inserting a usb otg and connecting mouse there and then rebooting. This is really a bad issue
