When comparing these two smartphones, the question is, 'Which one has a longer battery life?' The horizontally foldable Fold 3 has a battery capacity of 4400mAh, but the display area is large, and the vertically foldable Fold 3 has a battery capacity of 3300mAh, but the display area is small. Of course, the larger the display, the more battery it consumes, so it is thought that 'Fold 3 has a large battery capacity but the battery consumption is fast' and 'Flip 3 has a small battery capacity but the battery consumption is slow', 'Start using at the same time Then, which one will run out of battery first? '

So, keep playing NASA's LiveStream with the display brightness fixed at 100% and the volume maximized, and try to practice which of Fold 3 and Flip 3 runs out of battery first. Below is a time-lapse movie of the situation.

I checked the battery life of Samsung's foldable smartphones 'Galaxy Z Fold3 5G' and 'Flip3 5G' --YouTube


The experiment started when the analog clock at the top of the screen reached 0 o'clock.

About 6 hours and 45 minutes after the start, the Fold 3 runs out of battery first.

And the battery of Flip3 ran out after about 7 hours and 10 minutes.

That's why I found out that the Fold 3 runs out of battery earlier, but since it is 6 hours 45 minutes (405 minutes) vs 7 hours 10 minutes (430 minutes), it can be said that the difference is less than 10%.

Now let's find out how long it takes to charge. The Fold 3 and Flip 3 come with a USB Type-C cable, but they don't come with a charging adapter, so this time both devices will start charging from 0%

with a USB PD 2.0 compatible 18W USB Type-C cable. Then, about 40 minutes after the start, Fold3 was 50% and Flip3 was 56% ...

After 1 hour and 25 minutes from the start, Fold3 reversed around 90% and became dominant in percentage.

However, it was Flip3 that re-inverted immediately afterwards and reached 100% first. It took 1 hour 33 minutes for Flip3 to reach 100%, 1 hour 35 minutes for Fold3, and although the battery capacity is 4400mAh for Fold3 and 3300mAh for Flip3, the time to complete charging is almost the same. It was a result.

Samsung 'Galaxy Z Fold3 5G' and 'Galaxy Z Flip3 5G' will be released from DoCoMo / au in early October 2021. The price of Galaxy Z Fold3 5G is 237,600 yen including tax for DoCoMo, undecided for au. Galaxy Z Flip 3 5G is 148,896 yen including tax for DoCoMo, and it is undecided for au.
