I figured you would say something like that. The diode will not prevent current from flowing if the battery is backwards. In that case the power pack and battery both are pushing current in the same direction which the diode will happily conduct.
It will however, prevent current from flowing back into a charger that is unplugged from the power source.
The reality is the 1 amp diode is there to limit the current through the transistor base and so the collector which feeds the LED. So the 1amp diode is limiting the LED current.

My guess is that schematic misinterprets the nature of the yellow
disc. I suspect that it\'s not a capacitor at all, but is a
positive-temperature-coefficient thermistor - a \"soft fuse\". If the
output (to the battery) is accidentally short-circuited, the high
current flow through the PTC will cause it to heat up, increasing its
resistance, causing it to heat up even faster, causing its resistance
to increase even more... and thus limiting the current flow through
the short circuit. These PTCs usually have a \"hold current\" (which
they will allow to pass for an unlimited amount of time, at room
temperature) and a \"trip current\" which will heat them enough to cause
them to limit the current.
Since we don\'t have a profile view of this component and can\'t see
the markings, I can\'t tell for sure.

Look at the circuit diagram. The positive of the battery is only connected through a capacitor.
How can a capacitor possibly pass DC current to allow the battery to charge?

Never looked inside one in great detail. I assumed they were switched mode, since a £4 LED bulb from China is. Never tried looking inside a tiny one, like a plug in USB PSU.
The light bulb has to be a switched device. Transformerless units waste a fair amount of power. Lightbulbs need to be efficient as they consume a fair amount of power and they also need to regulate the current.
Actually I have an old one which is just a capacitor dropper. The capacitor recently exploded so I opened it up and replaced it with a larger one.
The lightbulbs are sold through retail establishments that expect a level of quality and safety.
I\'m not stupid enough to buy anything through an expensive retail establishment.
A typical wall wart isn\'t and doesn\'t regulate anything very well. The junk that are sold on the Internet are literally death traps. Watch one of Big Clive\'s tear-downs on various products. He finds dangerous stuff all the time.

I\'ve watched a lot of his stuff, but I\'ve never had a problem with a cheapo Chinese USB supply like this: https://www.ebay.co.uk/itm/303876456847

I assume you mean a capacitive dropper? I have an LED room light like that. That would be the capacitor limiting current in the AC part, but in this case it was in the DC part. I\'ve been told it isn\'t a capacitor, but an automatic resetting fuse, which looks exactly like a ceramic disk capacitor.

I\'m just guessing here, since I cannot see your circuit, but it used to be a

They consume a few watts, tens at most. not a lot of power.
a capacitive dropper is inherently current limited.
\"A few watts\" in most light bulbs is a lot more than a cell phone charger puts out. The purpose of LED light bulbs is to save power. Giving up 20% or more to the dissipative elements in a dropper makes the bulb significantly less efficient. No one buys cell phone chargers by their efficiency.
Being current limited is of no utility in this case.
That\'s what LEDs need, duh.
