Apr 17, - What to do if your phone charges too slowly on PC But in order to charge your phone with USB , you'll be needing a proper cable. Meaning that, if you plug in your device and select ”Charging only” mode, your PC will, For a faster charging, keep the phone plugged into the USB and the laptop.
Hmm, I have a new idea.
NormG NormG 18 6. I never answered if it was safe.
Yes, as the other answer states, it is safe. But it is like saying if I put my wet fingers across the terminals of a 9V battery, is it safe? Yeah, but why would you want to?
Because in the scenario you describe it will charge so slowly as to be useless. And it thhe charge at all if you are using the computer.
So sure, in an emergency, if you need to charge and have absolutely no other way to charge and have a ton of time to wait, go for it. Your advice sounds like the advice for very old NiCd or NiMH batteries which laptops haven't used for years.
It's very bad for lithium batteries to be fully discharged at any time. Usually a battery pack will shut of protectively well before zero. I reflashed the exact same version and the problem went away.
If that doesn't help, one test that might be interesting would be creating Windows 10 installation media get the Media Creation Tool can i charge my laptop through the usb port Microsoftbooting your system into porr environment, and then seeing whether phone charging works there. That would tell you whether your system can charge phones while a plain Windows 10 kernel dbpower waterproof action camera manual running.
If that works, my next step would probably be to capture chaege image backup of my hard drive use a tool like Macrium Reflect Free fharge then perform a clean Windows 10 install and see whether charging works when running a fresh copy of "full" Windows If charging worked at that point, I would probably decide that completing this clean install would be faster than continuing to troubleshoot my previous installation.
Hcarge it did NOT work at that point, then I would restore the image I had captured in order to avoid performing a clean install for no real benefit, but that point I'm not sure what I would suggest.
Is is totally not charging or charging very slowly which is what will happen at mA with USB 2.

Chaarge, any laptop that's awake should charge any device plugged into it, even if the computer isn't plugged into the wall. This almost always works — but a grossly obsolete Dell running Windows XP don't ask failed to charge an iPad mini and only started the flow of electricity to an Android phone after taking a minute or so to recognize that device as a form of external storage.
If the laptop is asleep chage plugged in, it should also still be able to charge a mobile gadget — that was the case with a MacBook Air and a vintage ThinkPad. But certain power-management settings in Windows can obstruct that as well in strange ways, and it's not hard to find reports from Mac users of equally mysterious charging failures.
What if the laptop myy asleep and running on battery? Some Windows laptops will let you get away with that, courtesy of USB ports that continue to channel power under those conditions — and even if the computer's shut down. The trick there is knowing what to look for, as there's no standard way to indicate this feature. For instance, that ThinkPad's sole "Always On" port can i charge my laptop through the usb port a yellow interior, while Dell PowerShare and Toshiba Sleep-and-Charge ports bear a tiny lightning-bolt icon on potr Mac, a similar logo identifies high-speed Thunderbolt ports.

Here's why: the USB ports on laptops function to dispense power to other devices and peripherals, which is why you can charge your iPad, iPod, and other devices by simply plugging them in. This means that any battery pack or power solution meant for your laptop needs to be plugged into the power port.
