The iPhone SE 4 is expected to have significantly improved battery life compared to its predecessors, particularly the iPhone SE 3. The new model is rumored to feature a battery capacity of 3,279 mAh, which is a substantial increase from the 2,018 mAh battery found in the iPhone SE 3. This upgrade represents an increase of over 60% in battery capacity, which should directly enhance overall battery performance[1][3][5].
Additionally, the iPhone SE 4 will likely be powered by the A18 chip, known for its energy efficiency due to its advanced manufacturing process. This chip is expected to optimize power usage, potentially allowing the iPhone SE 4 to outperform previous models in terms of battery longevity despite having similar battery capacities as the iPhone 14[2][4].
While the iPhone 14 also has a 3,279 mAh battery, the efficiency gains from the newer chipset in the SE 4 may lead to better real-world usage times. Current estimates suggest that the iPhone SE 4 could achieve around 10 hours of usage, significantly surpassing the 3 hours and 56 minutes recorded for the iPhone SE 3 during testing[5][7].
In summary, if the rumors hold true, users can expect a marked improvement in battery life with the iPhone SE 4 compared to earlier models.
