Akko 5075 V3 HE ghost input and battery defect.
Hey, I really like this board (Akko 5075 V3 HE). Response is great, 8K polling feels solid, magnetic switches are fun, and the RT feature in Valorant is honestly a big plus. Cloud profiles are also convenient for switching gaming/casual setups.
But I’ve been running into some issues that feel more than just software glitches.
1) Battery issue
- Charging from ~10% to 100% takes extremely long (often 10+ hours).
- After it finally shows “full charge” (Bluetooth + FN+Space shows 100%), the battery immediately drops.
- Example: from 99% → ~81% within ~2–3 minutes of use.
- This happened 3 times already.
- Tested on both Windows 11 and Fedora 43 (so not OS-specific).
- RGB is fully OFF (no lighting at all), so power drain shouldn’t be from that.
Context:
I’m using Bluetooth (low polling / low power mode ~125Hz). Even with that, the drain still feels off for a ~10,000 mAh battery. My older ~3000 mAh keyboard (also RGB off) lasted significantly longer (weeks to a month), so this behavior feels inconsistent.
Clarification:
* The instant drop only happens from ~99% to ~81%
* After that, the drain from 81% down to low/empty is not as instantly dramatic, but still feels unusually fast overall
* In total usage, the battery still drains faster than expected (roughly within ~12–24 hours even with RGB off and Bluetooth use)
At first I thought it was a reporting bug, but after repeated full charge cycles and identical behavior, it seems consistent.
2) FN+L (RGB off mode) ghost input issue
- If I turn off RGB using FN + L, the keyboard starts spamming random/ghost inputs and becomes laggy/unusable.
- This is also something I saw in other users’ reviews (Shopee Akko official store, 3-star section).
- Workaround: instead of FN+L, I set RGB brightness to 0 while keeping RGB “on” → no ghost input issue.
So basically:
- FN+L = broken / unstable input behavior for me
- RGB brightness 0 = stable workaround
Random key input spam happens even when the keyboard is untouched. Settings are left at default, so it doesn’t look like a configuration/sensitivity issue.
