How long will a phone’s battery last?

It’s difficult to give an exact estimate of how long a phone’s battery will last – battery life depends on the phone itself, how often you use it and what you use it for. Checking the following specifications on a phone gives you a guide on how long the battery will last:
 
Talk time – the maximum amount of time you’ll be able to make a call on your phone before the battery runs out.
 
Standby time – the maximum amount of time you’ll be able to have your phone turned on before the battery runs out.
 
Having facilities like Bluetooth or the internet turned on means your phone will drain your battery more quickly. Top of the range smartphones often do as much work as a laptop, so it’s no wonder that they need charging more often.
 
If a long battery life is very important to you, you might be better off opting for a more basic phone.
