Samsung E840 Battery Life and Miscellaneous

Battery Life and Miscellaneous

Battery life on the Samsung E840 is supported by a removable Li-Ion 690 mAh battery. The phone offers a standby time of up to 360 hours and talk time of up to 4 hours and 30 minutes, which is modest yet serviceable for a feature phone of its age. The absence of a 3.5mm headphone jack is noteworthy, as users had to rely on proprietary solutions for audio connectivity.
