If I power off my P8 (L09, B370) while it's plugged into a USB power source, it immediately turns itself back on again.
If I power off while unplugged, it turns back on as soon as I plug it in.
I've tried powering off from system, from TWRP, and from fastboot, all with the same result.
I've tried the original factory USB cable and various other cables.
Does anyone have a solution for this? I really need to calibrate the battery, which requires charging while powered off.
Thanks!

I think this is normal behaviour. If you start charging, then power off, the phone will not boot up. I think battery calibration is a bit overrated, fully charging, fully draining and then fully charging again should work.

Hello. I've bought today broken Typhoon. It doesn't turn on, but when i connected cables to the battery and then put battery in and hold a switch, red light appeared under the power button and sometimes display lighted white. When i'm plugging in charger, red light under the power button also appears. Any ideas, how is it broken? what should i do to repair it? help me please
which charger? the one that plugs into the wall or a usb cable that plugs into your computer? If it's into the computer, or not the wall plug that came with the phoen, then it's possible your battery is completely drained dead. When the battery is extra super low, the usb and some other chargers don't have the juice to charge it. You have to have the right wall plug charger i've found.
i'm hopin that's the thing....plug it in, charge it for a bit then try again. Also, once you get juice in there, plug it into the usb port on your computer and hit the camera button. that should jack it into the boot loader mode.

The batteries do die totally over time especially if they are charged from part full and never allowed to totally discharge. Do the do as described and if that doesn't work there are 10 on UK eBay right now one with 256Mb card for £25.00, you can't say fairer than that
Battery is too low in order to initialize the charging process.
Just plug in and plug out the wall charger until the LED turns orange.
When on battery power, it boots just fine. But if I plug it in, it shows the moto boot screen, and stays on it forever - and while it's on that screen, the battery isn't charging. I have to unplug it, take the battery out, then boot up without plugging it in. That itself isn't a problem...just a pain.
The problem is when my battery is too low to boot without plugging it in. I can't boot it up on battery power, and I can't charge the battery by plugging it in.
I finally got it to work by borrowing a friend's wall-mounted external battery charger and got the phone up and running. But what the hell do I do for next time?
Also, I installed CWM and it doesn't work, ironically, because CWM requires power to boot into recovery, and my phone won't boot at all when plugged in. The normal recovery has never worked on the phone, since its unboxing, and I'm starting to get pissed about this lack of recovery. Any ideas would be much appreciated.
Are you using a USB port to charge?

I've tried USB and a wall charger. When plugged into USB, it turns on but will not enter CWM still. When connected to a wall charger, it stays at the Moto screen forever, charging.
When the phone is switched off and plugged to the wall charger you need to do a long press on the power switch till you will see the Motorola logo again. Once the phone is fully booted it will start charging again (still plugged to the wall charger of course).
A friend has given me his 2012 Nexus 7 because it wont switch on.
I read many solutions on how to fix this but nothing works. I'm getting no responce from the device at all.
Heres what I've tried:
Leaving on mains charge for over 24 hours.
Long press on power button (30s+)
Disconnect battery cable & re-attach it.
Un-plugging & re-plugging in power & then trying to power it on.
Theres voltage going through the usb socket & I've measured power at the battery connector with my volt meter but its not powering up.
Now I've read that the Nexus 7 normally has a 5V/2A mains supply, however, I'm only using a 5V/1A supply which I use normally for my phone. Could this be why its not powering up as its not getting enough voltage to kick start it from being completely run down?
If its not the mains power, any ideas what could be causing the problem & is there any way to fix it?
Thanks.
When I plug charger LED blinks for a second and turns off, when I charged battery manually by putting the cables to V+ and V- for 5minutes the system booted, battery was at 20% and shows device is plugged in, but it's not charging it actually. While device stayed on cable for all night it was still 20% in the morning but as soon I disconnected it and battery went to 18% I plugged it back, after 2 hours it was still at 18%. system recognizes charger but not charging. I've also changed cable, adapter, replaced USB port and battery, but that didn't work. Now I have empty battery and it won't turn on for charging even in bootloader mode, as soon I turn recovery mode on it, device turns off and won't turn on again.
What's wrong? Is it motherboard problem and will repair cost more than new device?
Ok, seems the issue resolved when I disassebly phone completely and reassembled it, weird and a signal for phone replacement I guess.
Have had a stock Le Pro 3 since Dec 2016. No real issues prior to the last few days.
1. The device will only charge when powered ON. If powered OFF, the phone will vibrate once, the LED indicator will briefly come on, then turn off. Unplugging it and plugging it back it again does literally nothing--no vibration or LED indicator.
2. The device will not power on while plugged in. It will simply vibrate after a few seconds, then nothing.
3. The device will not connect to my PC for data. Have tried four different cables without success. It will charge from PC, however.
4. When connecting to USB and powered ON, the phone will vibrate and show the battery charging indicator, but will then hesitate slightly (battery charging indicator turns off), then shows the battery charging indicator again. Not sure if that means anything, just seems odd given everything else.
5. USB headphones do not detect/work.
6. The USB to 3.5mm adapter for headphones does work.
I've tried a factory reset to no success and have ordered a replacement USB C board just to be safe (it was $5 shipped), but am at a loss as to what to do. Tempted to let the battery drain completely and see if that puts everything into working order, but as it's my only phone, that seems a bit risky if I can't be sure it will ever start charging again while powered down.
Anyone here run into these sorts of issues before and any advice if you have?

A $5 board will not solve your problems. It will likely get you into deeper trouble because it doesn't support mtp and otg. It's only good for charging.
Your connector is probably damaged. You can try contact cleaner/lubricant on the connector. It may fix your issue. Something like this https://www.electrolube.com/products/contact-lubricants/eml/contact_cleaner_lubricants/
I use lubricant often on usb-c connectors even if they are working. Just extends the lifetime of connectors, the pins are really small after all so the contact surface is not much.
Replacing the usb-c board is not an easy task. You would need to remove the screen etc.
