> You need to remember that the battery temperature can influence a lot. The temperature does influence a lot, but it only influences within a range that's allowed by the current health status of the battery. In my mind, this status is what should be somehow visible / easy to check. As opposed to trying to estimate it given the current temperature and the reported range when X% full or whatever. My iPhone says its battery is X% healthy. I've seen my battery drain quicker when I was using the phone intensively by 0 °C than when it sat on my desk doing nothing at room temperature. But the health indicator didn't go up while in the office.
