Touch A question on battery life and charging the battery

anguila · 07-25-2014, 01:44 AM

If I charge my Kobo before the battery depletes, for instance between 20-30%, and I keep recharging never below that level, does that reduce battery life?

In other words, is it harmful to recharge the battery when it's not fully depleted?

I have this prejudice(?) that batteries have to be recharged only when they're almost out of juice, else their capacity declines quickly. Not sure where I've learned it.

The Kobo devices all use Li-Ion batteries. It is generally better for Li-Ion batteries to not completely discharge them. Completely discharging before recharging is more for NiCad and NiMH batteries. Li-Ion batteries are fine with partial discharge and recharge cycles. What you are doing is what is usually recommended for them.
