A mobile phone is an essential part of everyday life, whether this is to keep in touch with business colleagues, friends and family by calling or using social networking to be informed of what's happening. Not forgetting, receiving and sending emails, using the internet access or just listening to music and watching videos.

When the battery power goes from a handset all appears to be lost and you are left with nothing but a paper weight, but there are ways to prevent this from happening all too frequently and all too soon.

In this guide we are offering some useful tips and advice on extending the battery life of a mobile phone, which you may or may not already be aware of but a reminder nonetheless is always useful, from time to time.


The mobile phone's screen can draw a lot of power from the battery, depending on the display technology used and the size of the screen. A constant throughout this all of this is how often the screen is active, equals how rapidly the battery will undoubtedly drain. With this in mind, the screen's brightness doesn't always need to be as high as the mobile determines it needs to be.

A good deal of mobile phones, such as Android, have an automatic brightness function which self manages the handset when the surrounding light is either low or high - whilst increasing or decreasing when necessary, for the most optimal setting. This doesn't always need to be in use at every moment of the day and a manual adjustment could be more effective, as in a bright office the screen's brightness can still be quite high and it rarely needs to be.

Adjusting this setting to its lowest point will add valuable minutes to the battery life of the phone and it's always those last few minutes which are the most valuable, not the few hours beforehand. The screen will still be visible and usable at the lowest point, where some trial and error could be needed on the adjustment, to find the best viewing level for you.


Mobile broadband is a vital part of the use of a smartphone, feature phone and even the budget low-end devices as they too can have access to the internet and social networking sites, within the form of java apps or even direct access. Having the mobile broadband enabled at all times can dramatically impact the battery life of a handset, as the top tier devices all have access to HSPA+, HSDPA or 3G. These are great and very fast for internet use, but they do have an impact on the remaining power of the phone.

Completely switching off mobile broadband will save the most valuable resource of the phone, at the cost though - leaving the device without emails, social networking updates or internet access. Contrary to some speculation, text messages can still be received and sent whilst the mobile broadband aspects of the mobile are powered down.

As an alternative to losing complete internet access on the device there is a way to curtail the internet speed, as some handsets and mobile operating systems have a 2G setting that can be invoked. This will bring the speed down in loading webpages or downloading apps, but this will increase battery life substantially on a mobile phone.


After the two key battery drainers have been addressed, there are a number of minor, but nevertheless important ways of saving power. These fall into the realm of miscellaneous settings that although aren't as resource hungry as the screen or mobile broadband, are still every bit responsible for dragging down the power if not always addressed.

WIFI is always a good way to save that precious data allowance that accompanies a mobile, but forgetting to disable it can mean your phone will suffer, when it is not being used. A range of mobile operating systems and related handsets can constantly try and find an open 'free to access' WIFI hotspot, when away from the default home WIFI broadband. This continuous searching can have an influence on those battery resources, where just making sure the WIFI is turned-off when the leaving the home will show better results immediately.

Using maps on a mobile phone, checking into places on a Facebook and Foursquare regularly enables a better way of providing of location discovery, than triangulation through cellular towers. This is the phone's GPS feature. Although it is not a massive power drain when not in use, it has been known to have a slight impact on battery life when not used and therefore is advisable to have it powered down, when it's not expected to be used.

Following these tips will undoubtedly show benefits straightaway and will add those much sort after extra minutes, if not hours, to a mobile phones existence over a day - without the need to dash home, just to recharge the handset.
