The Samsung Galaxy ZFlip 4: The Battery

The battery is one of the key things when purchasing a phone. And this time, we are glad to know about the ZFlip 4 had comes up with a bigger size battery,  The good news that we have is the battery had improved comparing the ZFlip 3. In here the Galaxy Z Flip 4 comes with 3,700 mAH which is more than Z Flip3 400mAH.
With Standard Mode, the Galaxy Z Flip 4 lasted 8 hours and 57 minutes. The Galaxy Z Flip 3, on the other hand, only lasted 5 hours and 43 minutes with its adaptive refresh rate on. Compared to the Galaxy Z Flip 4 on the same mode, that's an extra two hours and 50 minutes. This is indeed a plus when it comes to me as I do not need to carry a power bank.  After a test with the Galaxy Z Flip 4, it could run the video for 9 hours 25 minutes before hitting 10% battery and entering the low-power mode, then it will mandatorily reduce screen brightness. It then toddled on for another 2 hours, 7 minutes, for a total of 11 hours and 27 minutes. And for Galaxy Z Flip 3 it can only run for 9 hours 30 minutes when it is on low power mood. With this, we are sure that, it is indeed a better battery compared to Flip 3. If you are looking at its charging performance, they are excellent too. The Galaxy Z Flip4 now supports up to 25W fast charging, you just need Samsung's 25W charger for that to work. The phone supports fast wireless charging at 15W, and it can also offer reversed wireless charging on its back. And with Samsung's 25W adapter gets the Galaxy Z Flip4 from 0% to 55% in 30 minutes. To conclude,  Samsung really made a substantial upgrade in its battery which is a double thumbs up on this.
