The iPhone SE 4 is expected to have a significantly improved battery life compared to its predecessor, potentially rivaling other budget smartphones with OLED displays[4][6][9]. It is rumored to adopt the iPhone 14's battery, which has a capacity of 3,279 mAh, a substantial increase from the iPhone SE 3's 2,018 mAh[1][4][7].
For comparison, the Samsung Galaxy A15 5G, a top pick for budget Android phones, features a 5,000 mAh battery and an OLED display[2][5]. While specific battery life comparisons between the iPhone SE 4 and the Galaxy A15 5G are not yet available, the A15 5G is known for its long-lasting battery[2]. The expected 60% increase in battery size, combined with a more energy-efficient chip, should give the iPhone SE 4 a competitive edge in battery performance within the budget smartphone market[4][9].
