TL;DRSamsung reportedly tested a 7,000mAh Galaxy S27 Ultra battery, but ultimately backed away from the idea.The current target is said to be 5,700mAh to 6,000mAh, potentially enabled by silicon-carbon battery tech.The unconfirmed leak also hints at S27 Ultra prototypes without the S Pen and a new Samsung over-ear headset.For years, Samsung has watched rivals turn battery capacity into a numbers game while the Galaxy S Ultra line remained stuck at 5,000mAh. That figure hasn’t changed since 2020, even as 6,000mAh and 7,000mAh batteries become increasingly common on competing Android flagship phones. Now, a new leak suggests Samsung may have secretly tested its own 7,000mAh option for the Galaxy S27 Ultra, only to back away from it this time.The 7,000mAh version was reportedly one of several prototypes. But Samsung is now rumored to be targeting a 5,700mAh to 6,000mAh battery instead, which is still a sizeable jump that could finally give the Galaxy S Ultra line the capacity boost it’s needed for years.
