I struggled for a while reading this question where the OP was asking for a consistent answer about the Android battery, battery calibration and battery usage.
He pointed out several answers from different users that present a conflict on advices on how should an Android user proceed with battery maintenance and usage.
The question raised on my head after reading this was:
Are we giving the appropriated information about battery usage and maintenance?
that in turn lead me here to discuss this matter, because if we've got contradictory information, some one is wrong or the specifics of each situation require a more careful explanation about the battery maintenance and usage.
Should we have a canonical question e.g.:
How do I take care of the battery of my device?
I believe for now, that this question would have an answer covering each scenario, or a single answer pointing to individual already existent answers for each scenario.
