Battery life was at about 7+ days expected, until it reached 12%, after 6 days, then it went to 0% in 2 hours.

This reduced the full battery from 100%-0% of over 7 days to under 6 days.

Hence perhaps the 35% low battery warning - the last 10% can't safely be used.

Even in the app it says not 10% if it is under 10% - very odd battery behaviour.

Charging it, it needs only 130 ma, instead of 300ma for a Sense, which implies the battery of about 162 mah might be confirmed, against 266mah for a Sense / Versa 3.

You may be onto something. I also noticed on Sense 2 that the last 99% to 100% charges a lot longer and it looks like GPS drains more power than on Sense (I believe it's the same GPS hardware but as you said, battery capacity is just lower).

@t.parker - well it took over 45 minutes to go from 99% to 100% which is absurd unless you want the absolute maximum duration.

It can charge from 0% to 99% in less than 90 minutes, 

It's not worth charging it to 100%
