How far in advance should a product warn you that the battery is low and in danger of dying? On many mobile phones, you will get “power saving mode” with around 20% battery life left. Depending on your phone, that might give it another hour of power.
My motorcycle Bluetooth helmet system gives an auditory low battery warning. It interrupts whatever I’m hearing to say, “Low battery.” Thanks! That helps.
Except it gives it one minute before the unit shuts down from being out of power. This makes me think the low battery warning happen with around 2-5% left.
Not helpful. Remember that warnings should help users fix the problems. Giving me one more minute of power while I’m listening to Google direct me is… not delightful. Give me a half hour or hour so that I know to charge up the unit.
