How long should battery charge take?

[Ryvius819]

I noticed that my battery takes a long time to charge, the meter shows around 90 minutes to charge up just 10%. Both istat and coconut battery shows that the health of my battery is healthy so is this really normal?

from what I understand, if it is last 10% it trickles it to reach the 100%

"Most lithium-ion batteries use a fast charge to charge your device to 80% battery capacity, then switch to trickle charging. That’s about two hours of charge time to power an iPod to 80% capacity, then another two hours to fully charge it"
