Does the 'Pixel 5a (5G)' with a 15% increase in battery capacity really have better battery life? I compared it with 'Pixel 5'

The genuine smartphone '

Pixel 5a (5G) ' released by Google is a low-priced model that boasts specifications that follow the 'Pixel 5' while being more than 20,000 yen cheaper than the high-end model 'Pixel 5'. Among them, regarding the battery capacity, 'Pixel 5a (5G)' is 4680mAh, 'Pixel 5' is 4080mAh, rather 'Pixel 5a (5G)' is 15% more, so actually measure the battery holding condition. I tried to.

This time, I will continue to watch the live video 'NASA Live: Official Stream of NASA TV ' released on YouTube by NASA with 'Pixel 5a (5G)' and 'Pixel 5' until the battery runs out. I checked it by the method. The actual comparison video is below, the one on the left is 'Pixel 5a (5G)', and the one on the right is 'Pixel 5'. Both devices have maximum brightness and volume, but since the movie itself is shot in time lapse, there is no audio.

I compared the battery life of 'Pixel 5a (5G)' and 'Pixel 5'-YouTube


I started shooting after 13:00.

At first, the playback status was synchronized on both devices, but the scene displayed on the screen is different from the middle because there was a synchronization shift in the middle.

'Pixel 5' goes down about 8 hours and 40 minutes after the start of shooting.

Approximately 3 hours after the 'Pixel 5' went down, the 'Pixel 5a (5G)' also went down. The total playback time was about 11 hours and 45 minutes for the 'Pixel 5a (5G)' and 8 hours and 40 minutes for the 'Pixel 5'.

Looking at the state of this measurement with an application that measures the remaining battery level, it looks like this. The graph on the left is the 'Pixel 5a (5G)', and the graph on the right is the 'Pixel 5'. The battery level is displayed as a blue line. The slope of the graph of 'Pixel 5' becomes gentle when the remaining percentage is a few percent, but other than that, both are consumed at almost constant speed. I started the measurement from the same time, but at 18:00, about 5 hours after the measurement, the remaining battery level was 51% for the 'Pixel 5a (5G)' and 36% for the 'Pixel 5'.

Now try charging. The same 9V / 2.0A USB PD compatible quick charger is used to charge both devices.

When charging from 0%, the remaining battery level was 69% for the 'Pixel 5a (5G)' and 78% for the 'Pixel 5' after 1 hour.

It took about 1 hour and 50 minutes for the 'Pixel 5a (5G)' and about 1 hour and 40 minutes for the 'Pixel 5' to complete the full charge. Considering the difference in battery capacity, I felt that the amount of charge per hour was higher for the 'Pixel 5a (5G)'.
