How does the battery life of the iPhone SE 4 impact its usability throughout the day

Battery Capacity and Potential Improvements:
* Larger Battery: The iPhone SE 4 is rumored to feature the same battery as the iPhone 14 (A2863), which has a capacity of 3279 mAh[1][4]. This is a significant increase compared to the iPhone SE 3's 2018 mAh battery[1].
* Increased Battery Life: The A2863 battery brings an increase of over 1250 mAh compared to the iPhone SE 3, potentially resulting in longer battery life for the user[1].
* Efficient Chipset: Upgraded chipsets in the iPhone SE 4 could further improve battery life because newer Bionic chips tend to be more power-efficient[4]. Even if the iPhone SE 4 does not come with an Apple-made 5G modem, its larger battery capacity alone should mean it comes with much better battery life compared to previous iterations[4].
* Cost-Cutting Measure: Apple's choice to use the A2863 battery from the iPhone 14 in the iPhone SE 4 is a cost-cutting measure, avoiding additional research and development expenses[1].

Other factors that impact battery life:
* Software Updates: New software can affect battery performance, and it may take time for the software to be optimized after an update[2].
* 5G Connectivity: Using 5G can drain the battery more quickly[2].
* User Habits: Turning off background app refresh, using Wi-Fi instead of cellular data, and disabling unnecessary features like location services and Bluetooth can help improve battery life[2].
* Recalibration: If a battery becomes uncalibrated, it may be necessary to recalibrate it by fully charging and discharging the battery over several cycles[2].
