'Finally, we've got silicon-carbon' — why SuperSaf is just as excited as we are for the Samsung Galaxy Z Fold 8 Ultra's new battery
A much-needed battery boost
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.
Now, as uninteresting as this may sound, it's actually pretty big news, especially given that the phone is thinner than ever and the same weight as last year's Galaxy Z Fold 7. We were invited to an exclusive, early-access hands-on session alongside SuperSaf to try out the new phones, and we discussed this change (and others) in our latest podcast episode, which you can watch just below.
It's not just us professional tech nerds moved to excitement by the news; in a poll we shared in the weeks running up to the latest Samsung Galaxy Unpacked show, our readers overwhelmingly agreed that a larger battery life would be their biggest wish for the latest and greatest Samsung foldable, and those prayers have been answered. Feels good, right?
The sad news is, the second-most desired change remains unmet — that being the re-introduction of the S Pen and the digitizing layer under the display that makes the technology compatible. In fact, as reported by 9to5 Google, Samsung recently quietly removed product listings for all previous-generation S Pens, which perhaps doesn't bode well for the longevity of the styluses overall.
It's a real shame, and one I highlighted in the podcast as being particularly at odds with the phone's productivity-first marketing messaging; if the idea is that the best way to use this phone is like a tablet, which, for me, includes doodling, taking notes and not having to constantly wipe off grubby fingerprints, then hand me the S Pen and be done with it, even at the cost of a few more millimeters thickness.
That being said, at least in the case of the S26 Ultra phones, a Samsung exec shared with TechRadar just last year that the S Pen is a crucial part of the phone's DNA, so I hope that gives at least a little more runway for these handy accessories.
