Battery Life
The Serene’s removable Li-Ion 800 mAh battery offers a standby time of up to 225 hours and a talk time of up to 3 hours and 30 minutes. These specifications were adequate for an era when power-hungry applications were less prominent, ensuring users could rely on the device for the essentials of communication. The daily usage cycle fits well with the phone’s minimalist proposition and the expectations of the time.
