In addition to Raja Ram Mummadavarapu's comments, Li-ion batteries degrade at a much lower rate when charged to 50% than when charged to 100%. That allows the device to sit on the shelf for a long time, without degradation, before it is sold. It would be disappointing for the customer to buy a new device and have the battery already "worn out" due to aging.
Also, charging to 50% instead of 100% reduces the energy used by the device manufacturer for charging.
