Samsung Galaxy Z Flip 3 Review : Darn Good Value!

Battery Life + Recharging, Performance

Samsung Galaxy Z Flip 3 : Battery Life

The Samsung Galaxy Z Flip 3 comes with a small 3,300 mAh battery.

To test its battery life, we turned off Automatic Brightness, and set its display brightness to 50%.

Why 50%? That is actually slightly higher than the average indoor brightness level of 40% during the day, and is what we usually use in all our mobile battery life tests.

It is important to fix the brightness level, to make sure the screen brightness does not change as the ambient brightness changes.

We then ran the PCMark Work 3.0 battery life test until its battery capacity dropped to 20% several times, and this was the best result we obtained with 60 Hz and 120 Hz refresh rates :

This is the biggest problem with the Galaxy Z Flip 3 – a relatively short battery life, because it pairs a powerful processor and a very large display with a small 3,300 mAh battery.

Even with the display set to 60 Hz, it only lasts just over 8 hours. If you set the display to dynamically adjust its refresh rate up to 120 Hz, that drops to just over 6.5 hours.

The Galaxy Z Flip 3 recharges very slowly, even using the same 15 watt Samsung fast charger as the Galaxy A52.

It actually took longer to recharge its smaller 3,300 mAh battery than the Galaxy A52 which has a much larger 4,500 mAh battery!

Its only saving grace – it was able to recharge slightly faster than the Xiaomi Redmi 9T.

For gaming, we tested the Galaxy Z Flip 3 using 3DMark, with these results :

Look at that – the Qualcomm Snapdragon 888 packs a serious punch when it comes to gaming.

It may seem unbelievable because the Galaxy Z Flip 3 is so slim and stylish, but it will easily handle any game you throw at it. Easy peasy, lemon squeezy!

The only problem is that because it’s so thin – it can get real toasty when you game on it. The back of the chassis can get as warm as 42°C.
