How Long do Cell Phone Batteries Last?

Determining how long cell phone batteries will last is not an exact science. There are many different factors that can affect the charge, and the overall life, of a battery. The key to understanding cell phone batteries is to first understand what affects that charge and try to conserve power whenever possible. In most cases, there are two standards by which cell phone batteries are measured. These include talk time and standby time. Talk time is usually measured in a matter of minutes or hours. Standby time can be measured in a matter of days, perhaps even weeks in long-life batteries. Over the years, the improving technology has made a significant difference in cell phone batteries. When the first analog cell phones first started becoming popular in the late 1990s, talk time was often limited to 30 minutes with standby time maybe going as long as 24 hours. Now, talk time is usually at least two hours, with standby time often running seven days or more. Cell phone batteries can vary ...  more

The exact amount of time cell phone batteries can last depends greatly on the amount of time the phone is talked on compared to the time it lies idle. Using the phone frequently consumes the battery at a much greater rate, and factors such as how often the battery is fully recharged are also very important.  more
