What mobile phone has the best battery life?
Paddy, via email on 14 October 2010
Modern mobile phones run for far longer between recharges than phones available five years ago.
However, the high-tech features of modern mobile phones - such as touchscreens and video playback - are known to cause even the most power-efficient smartphone to drain its battery swiftly.
No single mobile phone is recognised as having the “longest” or “best” battery life, mainly because the length of time a phone’s battery will last between recharges depends entirely on what you use it for.
For example, watch a film and surf the internet for several hours from your mobile phone and you can be certain that it’ll have little or no power left afterwards.
Conversely, leave the same phone on standby in your bag and it’s likely that the battery will hold out for at least one day - perhaps even several.
It’s generally accepted that basic mobile phones - those only suitable for making calls and sending texts - offer longer battery lives than smartphones.
As you start to compare mobile phones with good battery lives, the best factors to consider are:
Every mobile manufacturer lists the basic “talk time” of their phones, such as 300 minutes. The quoted figure relates simply to how long a phone’s fully charged battery will last if you only use the phone for making telephone calls.
Basic mobiles phones have been known to last for days in standby mode.
Smartphones don’t usually last as long in standby mode because their numerous features are often active in the background.
For example, your smartphone might still be checking for new emails while in standby. Leaving apps running will also continue to drain the phone’s battery.
How long your phone’s battery will last for if you only listen to music depends heavily on the phone. For example, the Nokia Nokia X2 has a “music playback time” of 25 hours, while LG’s KM900 Arena should play music for 30 hours.
A mobile phone’s battery life can also be impacted by music features, such as bass boost, an integrated speaker or graphic equaliser settings.
Accessing the internet from your mobile phone while connected to 3G will use more power than if doing the same from your home’s wi-fi connection.
Which webpages you visit will make little difference to your phone’s battery consumption, but downloading and uploading music, videos or pictures will use more power.
Mobile phones rarely have video playback times of over 10 hours.
