It looks like the unannounced Galaxy Z Flip 4 could solve a problem seen across the industry when it comes to foldable smartphones – battery life. Because batteries can’t bend along with the screen, they need to be smaller, which means most foldable devices don’t have much battery life. Even though Samsung’s foldable smartphones feature two batteries, one in the top half of the screen and the other in the bottom half, the Flip 3’s battery was perhaps its worst feature.
Fortunately, a report from the Galaxy Club says that the Flip 4 will increase its capacity compared to the Flip 3. According to the report, the “main” battery (as Samsung calls it inside) will remain the same at 903 mAh, and the “auxiliary” battery will be increased. from 2300 mAh to 2400 mAh. This isn’t a major upgrade with just 100mAh indifference, but depending on how it’s used, the Flip 4’s battery life could be extended over its predecessors.
Hopefully, Flip 4 owners will be able to see a noticeable improvement over the previous model, but given how small that increase is, it’s unlikely that too many people will notice it. Samsung sold the Galaxy Z Flip 3 with a 3300 mAh battery, even though it is much closer to 3200 mAh. We can only guess what this year’s marketing machine will be touting, but the Flip 4 will likely be touted as a 3400mAh battery, though the real number is closer to 3300. The ads may stick with the 3300mAh message if Samsung doesn’t see an increase in battery life, but if it wants to use “increased battery life” as an argument in favour of selling, then it’s likely that they’ll use 3400mAh. mAh in device marketing.
Currently, not much specific information is known about the Flip 4, as Samsung has not yet announced it. Looking at previous flip releases, it seems like it could come out in August or September, but that’s not confirmed. If so, an ad may appear soon.
