One important detail is that **Device 2 actually started the test almost 6 hours before Device 1**. More specifically, Device 2 had already been running for **5 hours and 57 minutes** before I was able to begin testing Device 1, as I didn’t have a second pair of wired earphones available at the time.

**Device 2** still has **Google Photos and the Google Play Store** installed.

**Device 1**, on the other hand, has **no Google apps installed at all**.

Despite starting nearly 6 hours later and having fewer apps installed, **Device 1 still managed to consume battery at a significantly faster rate than Device 2**.

For me, this first test strongly suggests that something unusual may be happening with Device 1. Since Device 2 had such a large head start and still performed better, I suspect there could be a battery-related issue with Device 1.

However, I will perform a **second, more controlled test** before reaching a final conclusion or deciding whether to return the device.
