The Du Battery Saver & Switch Widget has over 10 million users across the world. According to its developers, the new version of Du Battery Saver (version 3) follows a simple, streamlined approach to perform even better at saving battery life. The app optimises your device  to squeeze in some additional battery by shutting down or lowering the intensity of other features. We’ve tested the free version of the the Du Battery Saver&Switch Widget  for Android. Read on to know how it fares.

User interface :

The new version has introduced some cosmetic changes, and the overall user interface comes across really neat. The homepage of the app is divided into four tabular sections  – Battery, Saver, Charge and Monitor. Under Battery, it shows the percentage as well as time left before your battery goes kaput. There is a prominent “Optimise” button and just a single tap on it will take you to the optimising page. The Saver section is further divided into two parts – Mode and Smart. While “Smart” section is for Pro users, the “Mode” section lets you opt for custom usage modes. For instance, Long mode keeps your calls and SMS on and shuts down mobile data. Users can even customise or add new modes as per their mobile computing needs. The “Charge” section gives some gyan about three different methods of charging and the “Monitor” section displays how much charge is being gobbled down by your apps and hardware. On the upper right side corner, it has the Settings icon, which lets you tweak the features as per your needs.

The interface is undoubtedly slick and simple. Inspite of the comprehensive set of functions, it won’t take too long to get the hang of it. Options like optimising the smartphone, tweaking the settings and swapping modes are easy to use.

Features and performance :

As soon as you install the Du Saver app, you are greeted with a three pager introduction, and then you are good to go. The Battery section shows a large battery icon along with the percentage of charge remaining. But what we really liked is its ability to reveal how many hours more your battery will last. Now, if the time left is six hours and you want it to squeeze through, say, seven hours of battery usage, then simply click on the Optimise button. With a single tap, it takes you to a page wherein you are given options such as optimise screen brightness, set the screen timeout, disable Bluetooth or Wi-Fi and so on. The app quickly scans your device and shows the best possible options that will help you save some battery life. You can enable these options with simple taps directly on the Optimise page. Each option you enable will add some time to the battery life. For instance, by completely optimising the phone, we managed to extend the battery life by 1 hour and 16 minutes, and on another occassion by 45 minutes. However, there is no undo or disable option on the optimising page; one will have to manually turn on Wi-Fi, Bluetooth and other features. But the “Saver” section can come to the rescue here.

 The Saver section lets you choose from several battery saver modes. We really liked the Sleep mode, which disables all the power consuming features and simply keeps the clock and alarm on. This feature is also very helpful if your charging switch is away from the bed and you have to wake up in the next five or six hours. Simply optimise the phone or put it in the Sleep mode and the app will show how much power can be retained till your alarm rings. Other modes include Long mode, which only keeps calls and SMS active, and General mode, which keeps call, SMS and mobile data on. It features “My Mode”, which saves your current settings and lets you further customise them. Moreover, there is an option to create new modes and decide what features should be turned on or off. We could easily create modes and even swap between them effortlessly.

The app monitors and neatly displays which apps have been consuming your battery power. It also displays the battery consumed by other factors such as the screen, Wi-Fi, Radio, Bluetooth and so on. One will always find Du Battery notifications, giving a glance at how much battery life is left (percentage and time) at all times. Along with the battery life, it shows if key functions like calls, messages, Wi-Fi and mobile data are enabled or disabled. This ensures that you get a quick glimpse of the battery life anytime on your phone’s display.

 While the app worked smoothly all the time we tested it, we did face a hiccup. While testing it on the Galaxy Nexus, the phone stopped charging altogether and we could charge the device only when the Du Battery Saver&Switch Widget app was uninstalled. We didn’t find any such issues while testing it on other devices. The app worked smoothly without any lags. The app also shows a graphical representation of your battery usage. The graph gives a clear view of how the battery life has been depleting in every six hours of the day.


Apart from the glitch we faced while using it with the Galaxy Nexus, the Battery Saver app worked very smoothly. We liked its optimising features to save/increase the battery time and the several “Saver” modes that can be accessed with a single tap on the screen. You will not be disappointed with the UI either. If you are a smartphone user who usually frets over frequent battery power loss, then the Du Battery Saver&Switch Widget is worth considering.

 Du Battery Saver Pro version automates features from the Free version and adds up to 20% more battery life. Schedule power saving mode by power level or by time. Slow down CPU, remove power hogging apps and update device settings to boost your battery time.
