I tried to measure how long 'Xperia 1 V' lasts with battery drive & how much it heats up

When I'm out and about, I can spend half a day without even getting a chance to charge my phone. I actually measured how much the Xperia 1 V would run on battery power and how much it would heat up under load.

The appearance of the terminal is summarized in the following article.

In addition, the following article summarizes the photography and video shooting.

First, let's talk about battery life. Since this terminal was a test machine and it was not possible to use a SIM card, I decided to watch

YouTube playlists endlessly while connected to indoor Wi-Fi. When viewing, the screen brightness was maximum and the volume was medium.

Below is a graph created by checking the remaining battery level every 30 minutes. The vertical axis shows the remaining battery capacity, and the horizontal axis shows the elapsed time in minutes. Roughly speaking, at first it was a pace of ``about 10% less than 1 hour'', but the remaining amount reached 70% after 3 hours. After this point, it decreases at a pace of slightly more than 10% per hour, and the remaining amount after 6 hours is 34%. 7% remaining after 8 hours and 30 minutes, 1% remaining after 8 hours and 50 minutes. It was 9 hours in 10 minutes, but unfortunately the battery ran out without reaching it and the screen went dark.

In addition, when I took it out for shooting, I couldn't use the SIM card, so I carried it without communication. Even 0 times was enough. Recording video for a long time will consume a lot of battery power.

The result of charging using the USB PD compatible rapid charger '

Anker 511 Charger (Nano 3, 30 W) ' with a maximum output of 30 W is as follows. The vertical axis is the remaining battery level, the horizontal axis is the elapsed time, and the plot interval is 5 minutes. It charges to 19% in the first 10 minutes, then slows down a bit and recovers to 43% after 40 minutes. After 1 hour, it recovered to 78%, and finally recovered to 100% in 1 hour and 40 minutes (100 minutes). In terms of percentage, it is ``recovering 1% in 1 minute'', but in fact the initial response is large, so even if you forget to charge at night and can only charge until you go out in the morning, at least You should be able to get a limited amount of recovery.

Regarding heat generation, there is a model that has a problem that 'when shooting 4K video, a temperature rise warning appears and recording has to be interrupted', so we measured what happens when shooting 4K video. I tried. The shooting environment is indoors with a room temperature of 25 degrees.

As a result, 40 degrees over 20 minutes after the start of shooting.

After that, I checked the temperature occasionally while shooting all the time, but the maximum temperature was about 45 degrees, and it did not rise too much. In addition, since there was no particular problem even after shooting for 60 minutes, recording was stopped manually.
