Leaked CADs Show Samsung’s Four‑Model Galaxy S27 Line Adopts New Camera Plateau and Bigger Batteries

Leaked CADs plus tipster reports indicate a redesigned four‑model S27 line, larger silicon‑carbon batteries, preserved S Pen for the Ultra, a smaller Pro without a stylus, ahead of a planned Q1 2027 reveal.

Overview

  • Multiple late‑August CAD leaks and reliable tipsters corroborate a four‑model Galaxy S27 family: S27, S27 Plus, S27 Pro and S27 Ultra, with the Pro positioned between Plus and Ultra.
  • The S27 Pro and S27 Ultra share a new wide, horizontal camera plateau that puts lenses on a full‑width bar to cut camera wobble and free space for larger sensors and magnetic charging features.
  • Leakers say Samsung built Ultra prototypes that removed the built‑in S Pen to fit a 7,000mAh cell but has targeted roughly 5,700–6,000mAh for the S27 Ultra and about 5,200mAh for the S27 Pro using silicon‑carbon battery chemistry instead.
  • The S27 Pro is described as a smaller ‘Ultra‑like’ device at about 6.6 inches with no S Pen slot while the S27 Ultra is expected to keep the S Pen and a ~6.9‑inch display; final SoC choices, sensor sourcing and availability remain unconfirmed.
  • Context: silicon‑carbon batteries first appeared in the Z Fold 8 and enable higher capacity in the same volume, but supply pressures for advanced RAM and storage could still shape final specs, regional chips and pricing for the S27 line.
