The iPhone SE 4 is expected to feature an OLED display, marking a significant upgrade from previous SE models that used LCD screens[1][5]. This transition to OLED technology is anticipated to impact battery life, with both potential benefits and drawbacks[1][3].
OLED displays generally offer enhanced energy efficiency because they only consume power for the pixels that are lit[1][2]. This could lead to longer battery life for the iPhone SE 4 compared to its predecessors with LCD screens[1]. However, OLED screens may consume more energy when displaying predominantly white images, such as during typical webpage browsing or office-related tasks[4].
Additional factors, such as the inclusion of a more energy-efficient chipset and potentially an Apple-designed 5G modem, could further improve the battery performance of the iPhone SE 4[3][5]. The iPhone SE 4 is rumored to have a battery capacity of 3,279 mAh, a 60% increase from previous models[3].
It is important to note that features like an always-on display, which is compatible with OLED technology, can significantly impact battery life, potentially draining the battery faster[2].
