Take a look at the battery recharging speed of the Samsung Galaxy Z Flip 6, and find out how its two refresh rate options affect battery life!
Samsung Galaxy Z Flip 6 Refresh Rate Affects Battery Life!
The new Samsung Galaxy Z Flip 6 offers two refresh rate options (Settings > Display > Motion smoothness) for the main, foldable display:
- Adaptive : Get smoother animation and scrolling by automatically adjusting your screen refresh rate up to 120 Hz
- Standard : Get longer battery life by automatically adjusting your screen refresh rate up to 60 Hz screen refresh rate
By default, the Galaxy Z Flip 6 uses the Adaptive mode for smoother graphics, but you can choose to switch to the Standard mode for a longer battery life.
Interestingly, we found out that the display’s refresh rate actually changes in both modes. The only difference is the Adaptive mode switches between 24 Hz and 120 Hz, while the Standard mode switches between 24 Hz and 60 Hz.
In the next section, we will look at how the two refresh rate options affect the Galaxy Z Flip 6’s battery life.

Samsung Galaxy Z Flip 6 Battery Life Comparison!
The Samsung Galaxy Z Flip 6 comes with a larger 4,000 mAh battery, which is 300 mAh (8%) larger than last year’s Galaxy Z Flip 5.
To test its battery life, we turned off Automatic Brightness, fix the brightness level, and make sure the screen brightness does not change as the ambient brightness changes.
We also set its display brightness to 50%, which is slightly higher than the average indoor brightness level of 40% during the day.
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 the Standard and Adaptive refresh rates :
Even though the Galaxy Z Flip 6 only comes with 8% higher battery capacity, it actually delivered a significantly longer battery life of just over 11.75 hours using its default Adaptive refresh mode. That’s 2.5 hours of extra battery life over the Galaxy Z Flip 5!
When we switched to the Standard refresh mode, it delivered almost 14 hours of battery life. That’s almost 3 hours longer than the Galaxy Z Flip 5!
Let’s compare its battery life at 60 Hz and 120 Hz, against the Z Flip 5, Z Flip 4, and S24 Ultra smartphones.
Standard Refresh Rate (60 Hz)
The Samsung Galaxy Z Flip 6 naturally has the best battery life with the refresh rate set to 60 Hz (Standard) – lasting just almost 14 hours.
You can see just how more power-efficient the Z Flip 6 is compared to its predecessor – it uses 14.3% less power than the Z Flip 5. Coupled with an 8% larger battery capacity, the Galaxy Z Flip 6 offers 26% longer battery life at the Standard refresh rate!
| Work 3.0 | S24 Ultra | Z Flip 6 | Z Flip 5 | Z Flip 4 |
| Battery Capacity | 5,000 mAh | 4,000 mAh | 3,700 mAh | 3,700 mAh |
| Battery Life | 16 hrs 25 mins | 13 hrs 57 mins | 11 hrs 4 mins | 10 hrs 14 mins |
| Utilisation per min. |
4.06 mAh | 3.82 mAh | 4.46 mAh | 4.82 mAh |
Adaptive Refresh Rate (120 Hz)
The Galaxy Z Flip 6 continues to deliver much better battery life, even with the Adaptive refresh rate enabled – lasting just over 12.75 hours!
The Galaxy Z Flip 6’s power consumption per minute dropped by 16%, compared to Z Flip 5. When combined with the 8% larger battery capacity, the Galaxy Z Flip 6 offers 29% longer battery life at the Adaptive refresh rate!
| Work 3.0 | S24 Ultra | Z Flip 6 | Z Flip 4 | Z Flip 5 |
| Battery Capacity | 5,000 mAh | 4,000 mAh | 3,700 mAh | 3,700 mAh |
| Battery Life | 13 hrs 49 mins |
11 hrs 48 mins | 9 hrs 12 mins |
9 hrs 9 mins |
| Utilisation per min. |
4.83 mAh | 4.52 mAh | 5.36 mAh | 5.39 mAh |
Whether you wish to enable Adaptive refresh rate for smoother graphics is really up to you. On one hand, you get almost 12 hours of battery life with Adaptive refresh rate. On the other hand, switching to the Standard mode buys you two full hours of extra battery life.
Personally, I rather go with Standard mode for a longer battery life. I may not need the extra 2 hours, but using less power means less wear and tear on the battery over time.
Samsung Galaxy Z Flip 6 Battery Recharging Speed!
The Samsung Galaxy Z Flip 6 supports up to 25 watts of wired fast charging, but unfortunately, does not come with the charger in-the-box.
So we tested it using the standard 15 watt and 25 watt Samsung fast chargers that shipped with their previous smartphones, which is what we believe most users will end up doing.
| Charging Speed | S24 Ultra | S24 Ultra | Z Flip 6 | Z Flip 5 | Z Flip 6 | Z Flip 5 |
| Battery Capacity | 5,000 mAh | 5,000 mAh | 4,000 mAh | 3,700 mAh | 4,000 mAh | 3,700 mAh |
| Charger Output | 25 watts | 15 watts | 25 watts | 25 watts | 15 watts | 15 watts |
| Charging Time | 68 min | 106.5 min | 101.5 min | 105 min | 119.5 min | 129.5 min |
| Charging Speed (per minute) |
58.8 mAh | 37.6 mAh | 31.5 mAh | 28.2 mAh | 26.8 mAh | 22.9 mAh |
One “problem” with the Samsung Galaxy Z-series smartphones is that they charge pretty slowly, probably to avoid producing excessive heat, and to keep its thin batteries healthy.
The good news is – the Galaxy Z Flip 6 charges faster than last year’s Galaxy Z Flip 5. But you will still need to put up with relatively slow recharging speeds – the Galaxy Z Flip 6 charges slower with a 25W charger, than the Galaxy S24 Ultra with a 15W charger!
With the standard 15 watt fast charger, you will need 2 hours to fully recharge the Galaxy Z Flip 6. Upgrading to a 25 watt ultra fast charger only speeds this up by 18 minutes (15%). So if you don’t already have a 25 watt charger, there’s no real need to buy one.
Ultimately, the Galaxy Z Flip 6 has a battery life to recharging time ratio of about 7:1, which is 65% better than the Galaxy Z Flip 5 – mostly thanks to its much longer battery life. You get about an hour’s worth of battery life for every 8.5 minutes you recharge.
You don’t really need the optional 25 watt USB-C super fast charger, but if you feel it’s worth buying it for a slightly faster recharging time, here are some online purchase options:
- Buy in US : Charger only | Charger + cable
- Buy in UK : Charger + cable | Charger + cable
- Buy in SG : Charger only | Charger only | Charger only
- Buy in MY : Charger only | Charger only | Charger only
