This is the strangest thing I've seen. My battery on idle drains about 3-4% per hour, and I assumed it was due to having 5 background tasks + a few live tiles. However, I've done a reboot the past three days, and I've seen my battery jump back up. Today, after 10 hours, it went from 60% to 90%! Generally it's about a 5-10% jump, but this is the longest I've waited before rebooting.

This is a bit ridiculous, and I'd like to know if there's a solution for it.

Like many users have experienced, the battery indicator isn't as accurate as we thought. Sometimes you find the battery just pass adversely.
For a possible solution I collected from community- Re-calibrate your battery indicator by conducting several full discharge and charge.
But I think it's just a little help, the culprit is still MS has to provide bug fix on accuracy of battery indicator.

Isn't killing the battery considered a bad thing? So even though it says "60%", once it drops to 0, it should shut off, right?

Edit: If you can link me to the thread discussing this, I'd appreciate it.

It is not accurate not sure why this happens. If your phone crashes or you end up rebooting it, your battery percentage will significantly change.
