What about a StepUp that have it's output following the battery voltage?
I mean that, let's says that our step-up is able to output
- 1.5V
- 1.3V
- 1.2V
- 1.1V
- 1.0V
- 0.9V
Allong with a small and power efficient uC (like an Attiny9) that read the (real) battery voltage and switch the step-up to a close output value for the stepup.
Ultimately the lowest available value should be configured with the device cutoff voltage, so that we are sure that the voltage never goes off that limit.
What this will do
- Prevent unusefull consumption on the battery by doing a too high conversion from the battery voltage to the output voltage
- But better, the battery meter on the device will work as before.
What is unknown:
- Does this will have any effect on the "tap into 800000000% of the battery remaining" I'm not sure, that it would help, and anyway if the device also use a step-up this is still absolutely unuseful.
- The total use time may also get worst by using this (but can't be as worse as a batter raiser)
Ho and by the way Batteroo, you are not allowed to take my idea for your next device if you will be able to make another one. This is an Open Source Idea, with the only limitation that any company with a name that start with "Batter" won't have any right of use it, and use of this idea need to follow this license of course.
So joke apart, Batteroo don't try to patent this idea, or you will have to pay me as my idea will precede your patent claim.
