There are various smartphone accessories. Generally, the internet is the best place to shop for them, because the cost may also be less that the price in a physical store — particularly in the smartphone provider's store.
Chargers and cables – A charger and cable are normally included with the devices, since nearly all smartphones are rechargeable. Having at least one spare set is a good idea because cables can get lost or damaged.
Cases – A case is highly preferred for safeguarding your smartphone. They come in many materials and in varying degrees of device protection. Some cases are in the form of a holster than can be worn on the belt. If you want to know more about the smartphone, you can also go through the web.
Headsets – A set of ear-buds or earphones is usually supplied with a smartphone for listening to audio played back on the devices. Wireless headsets which eliminate the cable connection can also be used with many smartphones.
Screen protectors – Screen protectors are constructed of a clear plastic material which is attached to the touch screen with a special (usually water-based) adhesive. This can help protect the surface of the smartphone touchscreen.
Batteries – Generally, the battery that comes with a smartphone is rechargeable. If you be sure you recharge your device when the battery is low, you mustn't need a spare. However, spare batteries for smartphones with replaceable batteries are available in the $20 – $50 range, with some higher.
