Remember when phones used to last a week between charges? Sadly, this isn't the case with modern smartphones. Sure, they're pretty awesome with all the things they can do, but all these features take a heavy toll on their battery life. In fact, even the best phones may need a daily recharge if they're used extensively. But DU Battery Saver is coming to the rescue. It is a handy Android app that promises to extend the battery life of your smartphone by up to 70% by managing how power is consumed by apps and the device's hardware. Better yet, the software can be downloaded for free from the Play Store. Here's our hands-on look at what DU Battery Saver can do.

My Nexus 5's battery life is really bad,i have tried many battery saving apps but i am not satisfied with the results...now the only thing(software solution to battery drain) that interests me is Google's Project Volta.

Bitdefender Smart Battery Saver is another one. You can tweak wifi, data, sync time, night time and battery level to deep sleep. Add some closing app actuon and that's it. You can save some juice.

Hmm, I can make it through a solid day with my N5, and still have plenty of battery left when i get home. Chargers are as common as the basic cold, you'd have to work pretty hard to not have access to one in today's society. Of course there are exceptions, but that's a lot more rare then not having ability to recharge along way.

Maybe you are not a power user or you charge your phone multiple times a day....chargers are common but that doesn't mean that you keep charging your devices all the time, its like eating all the time to survive .

Tell me, why not charge as and where needed? What is the problem there? I eat, when I get hungry, not by a clocks dictation.

That's because it should at least work for a single day if its completely charged....for God's sake it's not a laptop that lies on the table most of the time...even the 9.7inch iPad doesn't need to be charged as many times as my nexus 5 but unfortunately I need my phone to be with me all the time and not the tablet. I don't like to be one of those people who are being called as 'wall huggers' these days.. And the batteries wear out after a few charge cycles...and I want my phone's battery to last for two years from the day that I bought it.

You are being unreasonable. Why is it a bad thing to charge, batteries prefer a full charge please do keep on draining it an see what will happen from empty to full charge, you will lose charge cycles in the long run, fact. I never said squat about laptops or their regiment. Do you not work an are stationary for a spell, drive a car...have a battery bank etc... power is everywhere, make use of it an don't worry about what others think ffs.

I have talked about laptops because it is okay if they require to be charged multiple times because they are on the table most of the time. I am not being unreasonable....all I am asking for is a single day on 100% charge. We have many electronic devices with us all the time, its not just a phone so charging any one of them multiple times daily is really annoying. Instead of worrying us so much, can't the OEMS just make phones a little (almost unnoticeably) thicker with bigger batteries....I think you are being unreasonable to the users because its a one time decision for the companies...and their decision can save us from years of inconvenience. Or at least they should make batteries that won't wear out for 2 or 3 years even if they are charged multiple times a day.
