Samsung is reportedly planning significant battery upgrades for its upcoming Galaxy S26 series, with the standard model being replaced by a more advanced “Pro” version, the Galaxy S26 Pro.
The Galaxy S26 Pro, code-named M1 with the model number SM-S942, is expected to feature a substantial battery upgrade to 4,300mAh, marking a 300mAh increase from the Galaxy S25’s 4,000mAh capacity. This upgrade is part of a series of enhancements aimed at improving the device’s overall performance and user experience.
In addition to the battery upgrade, the S26 Pro is anticipated to see a significant improvement in its camera capabilities. It is expected to replace the 50MP ISOCELL GN3 sensor, which has been used in the S23, S24, and S25 models, with a potentially improved sensor such as the ISOCELL GN5. Although the ISOCELL GN5 maintains a 50MP resolution and a similar pixel size, it is touted to offer enhanced autofocus performance and Front Deep Trench Isolation for Dual Pixel sensors, thereby providing better camera functionality.
The Samsung Galaxy S26 Edge, code-named M2 with the model number SM-S947, is also slated for a notable battery increase, reaching 4,200mAh. This represents a 300mAh bump from the S25 Edge, underscoring Samsung’s commitment to enhancing battery life across its flagship models. Furthermore, the S26 Edge is expected to be thinner than its current counterpart, which measures 5.8mm, potentially making it more sleek and appealing to consumers.
Rumors surrounding the Galaxy S26 Ultra suggest that it may receive a charging speed upgrade to 60W, surpassing the 45W charging capability of its predecessors. However, the battery capacity for the S26 Ultra remains uncertain, with sources indicating either a 10% increase to 5,500mAh or remaining at 5,000mAh. This ambiguity highlights the ongoing speculation and anticipation surrounding the specifications of the S26 Ultra.
The charging speeds for the S26 Pro and S26 Edge are not expected to undergo an upgrade, potentially remaining capped at 25W. This decision is likely influenced by their battery capacities, which are similar to those of the Z Flip7 (4,300mAh) and Z Fold7 (4,400mAh), both of which also have 25W charging limits. This suggests a strategic approach by Samsung to balance battery capacity with charging speeds across its device lineup.
