Sometimes my L5 does not start charging on plugin of the original power supply, also turning the plug does not help or trying it a few times. I don’t think that it is an contact problem because it starts charging being rebooted. What could I do without rebooting?

What’s the battery percentage?
I can’t remember the exact value, but it must have been below 50% because I was out for 4 hours.
What does “sometimes” mean more precisely? Do you see any pattern? What do you do to actually make it charge? Do you have to just reboot, or do you unplug the cable, reboot and then plug it again?

“sometimes” means once a month, more or less. Can’t see any pattern and normally I reboot and after it plugin the cable. I will gather better information from now.
My question was more: can I push the charging from shell w/o reboot?

Hard to tell without knowing why it doesn’t charge in the first place.

Last night I have had another such case. The battery level was around 30% and I tested two original power supplies (I have two L5). None worked. Then I did a reboot (without the power supply plugged in) and after this charging started as usual.
An output of tail -n+0 /sys/class/power_supply/*/uevent gathered when plugged in but not charging could tell something more.

had that happen to me once in two weeks, it was a little scary. i think the red charging light did not turn on when plugging in the charger.
reboot fixed the issue. the following likely wont show it since it has been a week:

Yeah, there’s no point in checking that when things work fine 
There are a few reasons why charging may stop working until a reboot that come to my mind, and checking this command’s output while in that state could point us to which one is it.

@dos caught it:
Whats happening:
- phone doesnt charge on charger and cable with or without PD,
- phone lock shows solid red LED indicating charging but it isnt charging,
- battery status indicator shows no charging or usb cable being plugged in while it is definately plugged in,
- phone knows when usb is unplugged because sound over headphones disrupts briefly,

OK, could you keep it in that state for a moment while I’ll prepare next things to check?
It would be helpful it you could catch the output of:
sudo i2ctransfer -f -y 0 w10@0x3f 0x16 0x08 0xff 0xff 0xff 0xff 0xff 0xff 0xff 0xff
echo 1 | sudo tee /sys/kernel/debug/tracing/events/tps6598x/enable
sudo cat /sys/kernel/debug/tracing/trace_pipe
during plugging and unplugging the cable in this state. The last command is going to block and wait for events to come, which is when you should do the (un)plugging, so don’t wait for it to finish (you’ll have to ctrl+c it anyway when you’re done).
In any case, it appears that the USB-C controller gets confused for some reason. Now I’d like to see whether it’s its firmware (in which case we likely won’t be able to do anything with it) or the driver (which would be a good news, as we can fix it ;)).
let me try the other cable again, ok its not charging again
Also, please tell what kind of cable are you using. The original thread was about the charger provided with the phone, USB-PD is complex enough that we can’t even rule out the problem with the cable (some are violating the specs and can in turn be picky).

ok apparently thats not a PD cable (a cable i found in my drawer) , surprised it doesnt charge even without PD, the Purism cable works and charges. I maybe mistakingly thought it was charging before due to red LED.
You will note
in your original configuration, for some reason it was only ‘negotiating’ standard USB-C power, not PD. In other words, either negotiation didn’t happen at all, or it did happen but it failed.
Why that is would be anyone’s guess … however I think the golden rule is: if you are having problems with charging, you must revert to the original Purism-supplied charger and cable for fault isolation.
Agreed it does not explain the red led charging indication though when not charging.
it was a non PD cable i am pretty certain of that now.
