The iPhone SE 4 is expected to feature a significant battery upgrade, potentially impacting its overall performance[5][2]. Rumors suggest the iPhone SE 4 will have a 3,279 mAh battery, which is the same as the iPhone 14[2]. This is a notable increase from the iPhone SE (2022), which has a battery capacity of only 2,018 mAh[2][3].
Expected battery improvements:
* Battery Life: The larger battery capacity is expected to substantially improve battery life compared to previous iPhone SE models[2][5]. The iPhone SE 3, for example, had an estimated battery life of just 3 hours and 56 minutes in lab tests[2].
* Power Efficiency: The iPhone SE 4 is likely to include a newer Bionic chip, which should offer better power efficiency[2]. Some rumors even suggest it may get the A18 processor, which would further enhance energy efficiency[2][4]. Apple is also reportedly developing its own 5G modem for the iPhone SE 4, potentially improving energy efficiency and reducing manufacturing costs[2].
* Charging: The iPhone SE 4 is expected to adopt a USB-C charging port, aligning with EU legislation[1][2].
The improved battery capacity and efficiency could lead to longer usage times between charges[4]. While the iPhone SE (2022) offered only 1.5 days of autonomy with moderate usage, the iPhone SE 4 could potentially exceed the iPhone 14's 9 hours and 28 minutes of battery life, possibly even reaching over 10 hours[1][3].
