Battery life poll on the Supernote Manta - what is the expectation?

I kept reading how eink devices have very long battery lives. 2 weeks! But my manta only has 3 days, reliably. Day 4 requires a charge. Hardly what i would consider "long" battery life.

Settings:

• -WiFi on.
• -No Load shutdown
• -Autosleep 15 minutes
• -Autopower off (the lowest at 4 hours)
• -Syncs only to Supernnote cloud.
• All my notes are "REal time recognition" which to be fair does claim additional power consumption.

Current example i was fully charged Wednesday morning and now on friday morning I am down to 37%.

Wanted to ask others if this is pretty normal for this e-ink device.
