No mention how old is the item.  Old batteries become stubborn: stubborn
to charge (charge rate slows down) and stubborn to discharge (run time
decreases).  Might be time for new batteries if over 3 years old.

If it is new (newly manufactured, not sitting in storage and merely
newly bought by you), it could be due to a crappy design in the unit.

From its specs: "Up to 5 hours battery life (depending on usage)."  Is
that considered long for a tablet?  Seems short to me.  According to
http://www.laptopmag.com/articles/long-lasting-tablets, 5 hours is about
half the category average for battery life.  If your unit has small
sized batteries then they might be limiting the charging current to keep
down the heat (to prevent battery damage or fires).

They may have figured that slow charging would mean longer battery life
(longer to get stubborn).  By striving to get batteries to last longer,
the units have a better chance to outlive the warranty (rather than them
reducing the warranty period which reflects negatively on product
quality to consumers).

"a change that could take the average life of a lithium-ion battery from
a couple of years to around 10 years."

In the past, 3-4 years was about the lifespan of a lithium battery (that
was in use, not just stored).  Twould be nice if they lasted 10 years
but not if they burst into flames with high heat due to high charging.
