Any way to have the Touch Pro operate on external power only when plugged in, leaving the battery alone if I have it set to not charge when connected to a computer?
Sometimes I hook my phone up and turn off the charging feature because I don't need it to be charging. It would be nice if it would run off the external source in those instances so that the battery does not continue to drain while the screen is active or I'm messing with the phone.
you might be able to pull the battery out.... but i don't know why you wouldn't just set it to charge? Its not going to kill your battery to do so and you will have more power later.

Is there any possible way I can power on my Universal without a battery? Please help I need to do this very badly. Thanks for the help.
If you are near pc, you can just take battery off and plug it in pc using usb.
Works for my Kaiser : )
With battery removed Universal will not stay on even for a second. Without battery only orange light turns on but the device remains shutdown if the cable is connected.
On my Prophet at least, if you plug it in, with the battery, and then start up the device, you can remove the battery and have it running off the Mains...
Universal cannot be tricked that way. It turns off, orange light on, when battery removed after connecting cable. Waiting...........
So, I accidentally let my phone run down to zero battery. Now it won't turn on, even when plugged in. It used to show the empty battery icon, but now shows nothing, not even that icon, or even the LED.
Anyone have any ideas, or places to point me out to.
I'm gonna leave it charging overnight.
So, leaving it charging overnight seemed to do the trick.

Use the electrical outlet charger (not usb pc or notebook), connect the device and hold the power button until start. (may take up to 2 minutes)
After the LED next to the front camera light up, release the Power button immediately.
The LED lights up for some time (in my case, more than 30 seconds) and may blink, then turns off and the phone will light up the loading screen with the battery indicator at 0% (zero percent), and turns off again.
Pressing the power button again, just once, without keeping it pressed, the phone will not turn on, will remain off (not rule because he can light with the target load, it depends on the charge status of the battery). But do not worry, leave loading for a few minutes without stopping and soon the phone will light up indicating more or less a 5% (five percent) of battery charging.
Now most importantly, do not connect or disconnect the phone from the charger until you complete 100% (one hundred percent) of the battery charge. This undoubtedly is the crucial and most important point of this walkthrough. I repeat: do not remove the charger or plug in your cell before reaching 100% (one hundred percent).

So my S8's screen cracked and digitizer gone, no response. So I purchased usb-c to hdmi with additional usb port. Was working great to transfer info to new replacement S8. That was until the old S8 battery started to die. So I thought to put into power saving mode without knowing that power saving mode disables usb accessibility functions, thus disabling my external monitor, mouse and access. I can access my old S8 for 2 seconds on ext monitor and mouse to try and disable power saving mode in those 2 seconds before power save turns on, but the screen has a lock on it and there is no way I'm going to unlock it and disable in 2 seconds. SO,
Is there a way to disable power save using only buttons? I have successfully booted into safe mode, but lock still present. With power save on, computer doesn't recognize, nothing usb works except charging im guessing. Thanks for your help!
Can you let the phone remain on to drain the battery out. Then plug in and fully charge. Turn on after fully charged. I think it will go back to normal . . . ?
Is there a mod for this somewhere? I'd love to stop the screen from coming on when plugging it in to my PC, my car for Android Auto, etc.
Even if you find a method, I'd recommend keeping it enabled, as it is currently the only way to know that power is flowing to the device. Without a charging LED or activation AOD, the phone gives you no indication of its status and could leave you frustrated the one time you plug it in and the other end of the cable isn't properly inserted.

I've had it on my phones in the past and LOVED it. I don't really need any visual indication of charging, I've never had any problems with plugging it in and it just charging.
I have an old CUBOT P20 "chinaphone" with Android 8.0 that I want to use as an IP camera and I need it to stay always on.
I have removed the battery and attached the usb power supply directly to the battery terminals and it works fine.
But to my surprise when I turn on the phone, the battery percentage begins to drop and when it reaches zero it shuts down like it does when the battery get low.
How could it be possible? there is NO battery, it's just my usb power supply connected at the battery terminals!
The power supply has plenty of amps (it's not a charger) and it seems that Android has a built in "countdown" that starts regardless of the battery capacity and shuts the phone off.
If I disconnect and reconnect the power supply and then turn on the phone the percentage of the "battery" starts again from 100% and then begins to drop. This is extremely annoying because I need to leave the phone always on without interruptions.
Is there a way to disable this android function?
