Design
Mudita Kompakt
Soft-touch casing and honest, simple industrial design. It is larger than other minimalist phones, which is exactly why its E-ink screen is so readable.
Sonim XP3 Plus
Every surface is reinforced. The keys are huge, spaced, and tactile; the hinge is rated far beyond typical flip lifespans.
Battery
Mudita Kompakt
The 3300 mAh battery is the largest in its class, delivering up to nearly a week of light use — the best endurance of any minimalist phone.
Sonim XP3 Plus
The removable 1550 mAh battery covers 1-3 days. Swappable spares keep field crews running through long shifts.
