FiiO X7 1.3 Firmware Update and Other Ramblings
After using the FiiO X7 for a while, a few problems showed up:
- When playing songs, it stalls once at intervals ranging from 30 seconds to a minute, and after stalling for about 20 seconds it resumes playback.
- Battery life feels like it should be around the officially claimed 9 hours, but standby is a real weak point, and there should be auto-shutdown.
- In the song titles on the device, the artist is all uppercase whenever it’s in English.
- Firmware updates on the device can only be done by copying to an SD card — it’s supposedly a smart device, yet no Wi-Fi updates.
- The breathing light stays on constantly, which is light pollution at night.
- The device formats cards as exfat, which doesn’t support long filenames.
So I was grumbling about all this when I found out FiiO had released firmware 1.3. The update method is the same as on older devices, but 1.3 does fix a fair number of things.
- First, the breathing light can now be configured.
- Second, there’s now a mode to auto-shutdown after a set number of minutes in standby, so long standby sessions won’t drain much battery, and overall it should beat the ZX1.
However, the most annoying problem — playback stopping — is still not fixed. I emailed FiiO and they suggested I try a different card.
