Red
Unit has gone into “battery critical” shutdown. No
power source suitable to recharge is attached (e.g. an
iPhone is not “suitable” and so no current will be
drawn from the iPhone). All functions are off, current
draw is a few mA from the battery, LED will blink until
unit is turned off or the battery is exhausted, appx. 48
hours in this state. Until the battery is recharged by
about 15% the unit will remain “locked in shutdown”.
Turn unit off, attach a charger, make sure charging commences and leave
unit to charge until blue charge indication turns off. Depending on charger
and discharge state this may be between 8 and 24 hours. It is possible to
resume use after partial charge, but it is best to restore the battery to full.
At this point the unit attempts to protect
the battery from a deep discharge that
would reduce lifespan. If resolved in good
time, there is no negative impact.

Unit has gone into “battery critical” shutdown. As part
of the shutdown the iDSD micro tests if a power source
suitable to recharge is attached (e.g. an iPhone is not
“suitable” and so no current will be drawn from the
iPhone). Such a power source was detected and the iDSD
micro is in full shutdown but recharges from the USB
Power Port.
Turn unit off (at which point the LED will indicate charging by turning a
steady blue) and leave the unit to charge until blue charge indication
turns off. Depending on charger and discharge state this may be between 8
and 24 hours.
At this point the unit attempts to protect
the battery from a deep discharge that
would reduce lifespan. If resolved in good
time, there is no negative impact.

(very fast)
The battery’s own protection circuitry has disconnected
the battery to prevent deep discharge that may cause
damage to the battery. The iDSD micro is inoperable
until the battery is restored to healthy status.
Turn unit off (at which point the LED will blink blue very fast). At this point
the iDSD micro will charge the battery under USB charging standard “flat
battery provision” at very reduced rate to avoid damage. Afterwards the
battery can be charged normally again (normally will be the case within <
30 min) the unit will return to normal charging with a steady blue LED
indication and leave the unit to charge until blue charge indication turns
off. Depending on charger and discharge state this may be between 8 and
24 hours.
In rare cases (actually so far only theoretical, we have not been able to
provoke this in practice) the battery may be depleted so much that after
the expiry of the 30 minutes for “flat battery provision” the battery can
still not be charged normally. In this case the unit will shut off completely.
Then the iDSD micro must be un-plugged/re-plugged from the USB port to
restart another 30 minutes “Flat Battery” cycle.
At this point the unit attempts to protect
the battery from damage. In this rare
instance, the impact if any is likely
minimal, but repeated cases of the
battery protection circuitry engaging may
impair battery life.
There is no other risk as the protection
circuitry prevents battery states that may
result in damage.
Worst case scenario, have your micro
iDSD serviced by an authorised repair
centre - to exchange the battery.
