A mobile phone has a housing having a battery chamber for selectively accommodating a rechargeable battery. The mobile phone includes a battery latch and a latch coupling element. The battery latch is movably connected with the housing for locking or releasing the rechargeable battery. The latch coupling element is disposed on the housing adjacent to the battery chamber. The battery latch, corresponding to the latch coupling element, reciprocally moves along a direction parallel to a longitudinal axis of the battery chamber. When no force is exerted on the battery latch, the battery latch is in a first position. When a predetermined force is exerted on the battery latch, the battery latch moves a predetermined distance to a second position to release the battery from the housing.
