When it comes to battery life, foldables have it harder than regular phones. These devices need to power not one, but two screens (one of which is twice as large as the other), and so it's important to pick a model with decent endurance if you don't want to lug around a portable battery at all times.
Yet in the throes of a seemingly unquenchable thirst for thinness, Samsung has somewhat neglected the battery tech in its foldable phones. That is, until now, because the brand has finally introduced silicon-carbon batteries in its latest devices, the Galaxy Z Fold 8 Ultra and Galaxy Z Fold 8. The former, specifically, packs a 5,000mAh cell that, based on Samsung's own testing, offers 27 hours of video playback.
