Hey guys!
Unfortunately I have a problem with my aneng Q1.

When measuring the current consumption, I mistakenly placed the test leads in place for a maximum of 200mA, but the consumption exceeded 200mA, and as a result the multimeter only turns on and beeps but does not display any information on the display.
Another interesting detail is that when I put the multimeter on the DIODE scale, it beeps continuously.
I also verified that R18 broke and Q5 was open, but even after replacement the problem persists.

Do any of my friends have any suggestions to help me solve this problem?

Thank you very much in advance!

Fungus:
What did you connect it to? There should be a fuse inside these to protect against this.

It sounds like it's very broken, maybe the chip is blown and it can't be repaired.

At this price I'd just replace it.

On AliExpress, I discovered stabilizers 3V0

€1.73 | 2x 3.3-6V to 3V DC-DC Step-Down Power Supply Buck LDO Module Voltage regulator Board for 18650 li-ion AAA Dry cell batteries

 (max 300mA) with a low voltage drop and a consumption of 0.008mA. When a given multimeter sees a little more current. I installed the battery (glued with double-sided tape) and charging circuit. The connector is glued with instant glue. More on the pictures. The question is whether the glue from the charging circuit holder won't melt :D

P.S:The battery had to be turned the other way around so that the wires went directly to the charging module.
