Most 4G flip phones use a 2.8" main (internal) display and many include a smaller external (cover) display around 1.77". In practice the typical dual-screen setup is a 2.8" internal screen plus roughly a 1.77" exterior screen.
Listed battery capacities include 1350 mAh, 1500 mAh, 1850 mAh and 2000 mAh. Reported talk times span roughly 5.33 hours up to about 14 hours, and standby times are described as lasting multiple days on some models. (Note: exact runtimes vary by model and usage.)
Rear cameras are commonly listed as 2 MP or 5 MP. Many listings note no front-facing camera, though a few specify a front-facing camera (for example, one listing shows a 5 MP front camera).
Common connectivity features include 4G/4G LTE cellular, Wi‑Fi, Bluetooth (various versions), mobile hotspot capability, GPS and a microSD slot for expandable storage.
Some packages include removable batteries, USB Type‑C cables, cleaning cloths, extra back covers, stickers, charms, a beaded lanyard and quick-start guides. Several listings also bundle a preinstalled SIM or a one-year service plan (examples shown in listings include 1,500 minutes, 1,500 texts and 1.5 GB).
Some listings list IP ratings such as IP52 or show entries like "IP00," while a few list hearing‑aid compatibility ratings (for example, T4/M4 or M3/T3). Several other listings do not specify durability or accessibility ratings. Because notation and availability vary by listing, check the product details for the specific model.
