Battery low - prediction

[Steve81uk]

So, I usually just wait until I get a email notification about low battery , set to 10%. And the put it on charge. Tonight however my 10% was quite literally when my routine for sleep starts. So now I am going to miss out on sleep starts tonight.

Was wondering if there was a way to get a more predictive setting. To work out how much battery could be left by the time it's bedtime..

@Steve81uk   There is no way to get a more predictive setting.  Daily battery use will change depending on how you use your device.  I hope my explanation will help you avoid this situation.

I strongly recommend you change your battery charging habits to improve your long term battery health.  Here's a lesson in lithium-ion batteries.  Li-ion batteries are said to have a certain number of charge cycles in their lifetime, but not all cycles are created equal.  Letting your battery get down to 10% is known as a deep discharge.  Deep discharges are harder on batteries and shorten their lifetime.  You shouldn't go below 20-25%.

I always charge my Fitbit while I'm showering.  My first two wrist Fitbits weren't safe in the shower.  Fitbit recommends not wearing them in the shower because repeated exposure to soaps, etc., can weaken the seals.
