Can you set 95-90 and check is it freeze on reinit or not? Also what you have on others players after reinit on internal flash? Is it freeze or not?

I had the fuze var0 running now @92 for 2h: 2,9,0,0 but still responsive, can use the file browser and launch other songs.


On my clip+ on reinits it was mostly stuck or incrementing the counters or it even crashed with dc_write_callback etc.

You mean clip+ v1? On clip+ v0 it just crash/panic at low voltage?

johnb:
Mihail, I am afraid I did not note that down properly and need to re-run ...

johnb:
Fuze var1: crashed in less than 30min with "data abort" @81, prefetch data abort to be precise.

clip+ var0: I ran without any re-inits for more than 5hs at even 74, flickering got even worse. It got stuck when I navigated through the shortcuts, still playing the song. I could stop the song, but stayed in shortcuts and then idle powered off.

asymsucon:
For internal flash 86-88 on CVDD2 seems to be the most stable overall. Unfortunately all my units are only var. 1.
Except for the Clip+ with faulty internal flash, all other 5 run very well on 88.
If we could move on to the SD card testing, I'm getting 2 extra 64GB microSD cards, Transcend and Samsung.
I'd imagine no issues on v12 for those, but this 128G Sandisk is still giving me tons of reinits and causes Clip+ to be very slow (even browsing through dir structure).
Loading and seeking through Opus takes anywhere from 3 to 15 seconds.
DOOM takes forever to load (after 10 mins I performed reset)  :)
IT/XM modules vary between 1-3 minutes.

After 3 hours of continuous playing I was at 0,0,134,0

But despite this slowdown, I'm fairly certain we're close to 30 hrs target runtime. After those 3 hrs, the battery percentage dropped just by 8%.
