How my e-reader lost its stripes

The author describes how their e-reader, a Kobo Libra H2O, started losing its stripes, which are the physical indicators of battery life, after using it to read for an extended period. The issue was initially thought to be a software glitch, but further investigation revealed that the problem was with the device's hardware. The author was able to diagnose the issue by monitoring the device's behavior and observing the battery life indicators, which were not accurately reflecting the actual battery level. The author suspects that the issue may be related to the device's capacitive strip that monitors the battery level, which may be malfunctioning.
