One of the horrors of the smartphone age is running out of battery life. The SMRT recently installed charging points for mobile devices at four train stations.
Beyond charging on the run at train stations, what else can you do to keep from running out of battery? There are, literally, a battery of apps to help you track the battery life of your iPhones. We look at some of the most popular apps which pop up in the iTunes story when you look for "battery saver for iPhone" and do a quick comparison of functionality and interface.
Here is a run-down of five of the apps we tried.
Free from iTunes
This is the first app to pop up on the search and it is easy to see why it is popular. Besides being free, it is slickly and professionally presented. There is a short introductory section which tells you the app's various functions, including an option to boost your RAM and another which helps free up space on your phone.
Not quite sure what the latter function does, but there is an impressive animation on the screen when the cache clearing is at work and at the end of the scan, it does manage to find more space on my phone.
The app will also keep track of when and for how long you have charged your phone over a period of weeks in addition to the basic information about how much battery life remains in your phone.
After a comparison with other apps, this one gives you the most functions without actually making you pay for it.
Battery Life Magic
Free from iTunes
The second app to pop up in iTunes' App Store does not have such a nice interface. But it tells you instantly at a glance exactly how much time you have left for each application, whether it is YouTube/FaceTime or GPS navigation.
Unlike Battery Saver, however, there are no other functions to help you clean cache and sort out memory space.
Battery Life Saver
Free on iTunes
Nicely designed interface which greets you with a quick run-through of its functions, from finding out "Remaining battery time for what you do", to an "Optimizer" to clean up memory usage. This one gives Battery Doctor a run for its money, with additional functions which tell you which app consumes the most battery life and a Battery Life Saver which claims to help keep your battery healthy while it is charging.
