Skillhunt H03 problem

I have had the Skillhunt H03 (neutral white) for more than a year now. I used it quite a lot in a first couple month of its arrival and also dropped it a few times during this period but everything was working perfectly normal. Later on, i have more lights coming and it has been my shelf queen the last two month (with no battery in it). Yesterday i decided to use it so took it out, put freshly-charged HG2 in it and it still work. The problem is the Turbo mode now is just about 300 lumens. The UI still stay the same but every mode now is just much dimmer, about one-third of the normal brightness (Low 2 used to be 0.5 lumen and now about 0.1, Mid 1 70 lumens now about 20 lumens, etc). I already check the battery voltage, try using different cells, clean all the threads and contacts but it still behaves the same.
Has anyone ever experienced the same thing on Skillhunt H03 before and what should i do now ? Thank you in advance

If all are works and modes decreases proportionally than you could check , resistanse of R082

Did you try to double-click? Every mode in H03 has two possible levels.

I’ve already tried that. My light still have 4 modes and each mode still have 2 settings for brightness just like normal. Basically beside brightness, it functions normally. UI is still the same, all shortcuts and mode settings work fine but the brightness on every modes is about one-third the normal brightness.

This is the most probable cause. By pass it! :smiling_imp:
