Drain the battery on a cell phone by leaving the phone on.

You've just gotten a new phone, but instead of throwing away your old one, you want to store it for emergencies. Before you put it away, you should give some thought to the battery. If you are storing a battery for a cellular phone, it's best to store it empty, or almost empty. Long term storage of the lithium ion batteries that cell phones use can lower the total storage capacity of the battery if it is stored at full charge.

Step 2

Leave the cell phone on until the battery drains. This may take several days. You can speed the process by talking on the phone, since cell phones have a shorter talk time than standby time.
