Why do batteries always die at the worst time?
The Real Answer
Batteries don't actually choose inconvenient moments to die. The failures that interrupt something important are simply far more noticeable and memorable than all the ordinary times a battery runs low when nothing important is happening.
There is also a practical reason the timing can feel suspicious: people often keep using a device after the low-battery warning appears, especially when they need it most. That means the final few percent is frequently being consumed during navigation, an important call, travel, or some other moment when losing the device matters. The battery's timing isn't getting worse—the consequences are.
Your phone dies at 2% battery on a highway with no exit in sight, and somehow you blame the phone instead of the fact that you've known for three hours it was at 12%. You watched it happen in real time and did nothing. The phone is just the most recent thing you ignored until it stopped working.

A battery failure barely registers when nothing important depends on the device. The same warning feels personal when navigation, a call, or a deadline is involved, so the inconvenient failures are the ones that stick.
