The Measurement I Kept Skipping

For months, I had a gap in my test notes. I would only measure the device when it was most interesting, right after a heavy scene, a long export, or an event that compelled me to write something down. However, this instinct was actually the opposite of what I needed. A reading taken at the peak only tells you about the cooling system under a spike.

On the other hand, a reading taken ten minutes after the peak reveals the device's actual behavior when held. I started using a fixed mark - twelve minutes after each scene ends, without exception - and my notes became less dramatic and more reliable. Previously, sessions that were described as "hot" and "fine" now showed readings of 41 and 38, which could be easily explained rather than described as emotions.

The same approach worked for battery notes. Instead of saying "drains fast," I now record the percentage at the same two marks every session. For example, one percent every eight minutes is ordinary, while one percent every four minutes in the second half is a pattern. In my case, it wasn't the chip causing the issue, but the screen staying at full brightness on a page that never idled.

This simple change was the only part of my notebook that survived the second week of testing. If you're starting a log like this, pick the fixed mark before you begin. Any mark will work. The key is the discipline of the mark itself.
