Nexus 4 doesn't charge after battery dies

I ran my Nexus 4 battery completely flat and then when trying to charge with the USB cable out of my laptop I could not get it to charge. I tried several laptops or hubs and no luck. No battery icon on the charge screen, nothing, even if I left it in several hours. After a day of this I plugged it into the wall charger and boom it charged as normal.

So! If you are having problems charging from USB once your battery has gone flat make sure you have a wall plug adaptor. This is an absolute nightmare if travelling unfortunately as I usually don't bring a wall plug and usually do run it flat!

I once did not charge my Nexus 4 for about a week after the battery died. It took four hours of charging from the wall charger before it even started to show any signs of life.

Thanks...
Yep. That is why Apple rule! :p Just kidding.

Even before Android and iPhones some phones required the full kick from the wall
to revive once completely flattened.

I'm not overly surprised by the op, usb is a bit weedy.
I don't use usb for charging so no idea if my devices would react the same way.

Why?

I'd have been panicking before that I think, well if I noticed anyway as usually charge overnight.

A lot of phones will not charge from non-factory charger if battery is completely empty - this is a well known fact.
I haven't seen phone that wouldn't charge from PC UBS, given that you have correct drivers installed. Without drivers phone will not charge, if completely drained. This has to do with how over-voltage implemented.

Make sure you have correct driver installed.

Thanks for the discussion everyone! Smart group on here. CTPAHHIK - interesting. I didn't know it would have anything to do with drivers. Are you saying that because the battery is completely flat it over voltages the usb port for that first 'second' until it can stabilise a charge? I haven't had a phone before that I couldn't charge from USB even when flat (excepting flat-for-a-month flat).

There is power management function build in into circuitry that detects voltage (for sure) and some other things (don't remember) - this is what tells you that charger is wrong. Remember dumb phones that wouldn't charge from non-manufacturers charger? This is there to prevent damage to the phone (like frying it). When you plug anything other than original charger verification fails on hardware level and phone wouldn't charge.
The rest of power management functions are done in software. If your battery doesn't have enough juice to load up basic boot loader/kernel functions software will not load and phone will not charge.
Correct driver on PC will pass hardware power management check. It's not USB media transfer driver that is basic data transfer protocol, but boot loader/kernel driver specific for your phone. This is the one you would need to recover bricked phone.

It's not 100% correct for every phone, but it's a general idea of how it's implemented on most phones and laptops.
