Following rumors the Samsung Galaxy Z Flip 4 would sport a larger battery, new details have emerged about exactly how much bigger it will likely be.

The Galaxy Z Flip 3 is one of the most popular flip phones on the market but was widely panned for having too small a battery, coming in at a mere 3,300mAh. One rumor suggested the new model could receive a modest bump to 3,400mAh, while another rumor suggested it would be a more substantial 3,700mAh battery. According to MyFixGuide, it appears the latter is more likely to happen.
