The number one complaint among smartphone users is "not enough battery life"! We’ve all been there, desperately hugging the charger towards the end of the day to get some juice in to power up the Droid. My Samsung Galaxy Tab 3 lasts a little less than a day on full charge, and the DU Battery Saver/Power Doctor was offering up to 50% more battery life, so I thought why not?
After all, every few minutes count when you’re waiting for an important call or trying to watch that YouTube video that just can’t wait till you get back home.When it installed and opened for the first time, the app added a little’Optimize’ shortcut to my home screen.It opens at the’Battery’ screen, one of its four sections, which shows me the charge on my battery, along with the number of hours remaining before it’s time for the next charge.
The screen also shows me the battery temperature(which has been between a healthy 20 degrees C to 31 degrees C for me depending on how aggressive my settings are), the voltage and my battery capacity.These are useful bits of information to have, especially when you want to put your battery through healthy charge cycles and prolong it’s life as long as possible.
There is also an area that displays the battery usage in the form of a graph, so you can see how your battery is performing over time.The Optimize button scans through the background apps, sensors, brightness and other power-guzzling elements and removes programs running in the background.The Saver tab takes you to a screen where you can select the mode you want your phone to run in. There are a couple of pre-set modes: Prolong, General, Sleep and My Mode. Calls and SMS are on in all the modes, but screen brightness, WiFi, Sync and Mobile Data statuses change among other things. You also have the option of adding your own custom mode for quick access. The tips on how to prolong your battery life is a useful addition. In the app’s Charge tab, you will find brief information on Fast Charge, Full Charge and Trickle Charge concepts during your battery’s charge cycle and how best to charge your Li-ion battery to help it retain its maximum capacity for longer. There is probably more you can do with this information with the Pro version.
