That's the situation where the phone battery, with no different use by the owner, suddenly drains for no apparent reason. It turns out this is often caused by Google, and there's a simple way to halt the drain.
(April 2014) (Learn how and when to remove this template message) A network host is a computer or other device connected to a computer network. A network host may offer information resources, services, and applications to users or other nodes on the network.
A parasite is an organism that lives in another organism, called the host, and often harms it. It is dependent on its host for survival-it has to be in the host to live, grow and multiply. A parasite cannot live independently. Although a parasite rarely kills the host, in some cases it can happen. The parasite benefits at the expense of the host-the parasite uses the host to gain strength, and the host loses some strength as a result. Parasites, unlike predators, are usually much smaller than their host.
