Sponsored App Review: DU Battery Saver丨Power Doctor Update


We’ve taken a look at DU Battery Saver before in the past, but it’s recently been updated with a couple of big new features, and of course some more polish. This version has been fully optimized for Android 5.0 Lollipop and the new DU Aurora Engine promises to save 60% more battery life than before by tackling apps that consume battery in the background. The new Notification Saving feature uses this new DU Aurora Engine to prevent apps consuming battery life by sending you notifications in the background. This not only helps save you battery life, but also helps you cut down on the noise as well. Let’s take a close look at what this latest version of DU Battery Saver and Power Doctor has to offer, shall we?

Just as before, you’ll need to download DU Battery Saver from the Play Store to try it out.

When you first get started, you’ll presented with an overview of how much longer your battery has left, and over time you’ll see statistics of what users battery the most.

The two new features of this update can be found under the ‘Saver’ tab and are called “Advanced Saving” and “Notification Saving”.

Advanced Saving needs a little setup, and needs to be enabled in the Accessibility settings of your device, but DU Battery Saver goes over how to do this nice and quickly.

This Advanced Saving mode focuses on apps that are running in the background, and looks out for apps that might not seem like they’ve been consuming battery, but they have been. It also lets you know how long these apps have been running for and consequently how long they’ve been draining your battery.

When you save power with any of these modes, it’ll outline how much you’ll save.

This new feature is an excellent addition to DU Battery Saver, but one of my favorites still remains the different power saving modes. These are scientific modes that genuinely save power by turning aspects of your device on or off, but what I really love is the ability to create your own modes. Like this one here for a “Night Out”. I don’t care about all the bells and whistles of a phone while I’m out, I just need it to last all night in case something comes up or I need to ring a taxi last minute. So, I created a neat little mode that should get the most out of my battery.

You can add a number of your own modes as well as choose from some helpful presets.

There are other key features that make a happy return as well, like the neat and easy o use notification from DU Battery Saver (which you can turn off in the settings).

Plus, you can use DU Battery Saver to get a lot of information on how well your phone is charging. This is one of the best ways to find out if your USB adapter is a fast or slow charger I’ve found.

Of course, you can always change the look and feel of the battery as well, which is nice.

As I said at the beginning, this is not the first time we’ve reviewed DU Battery Saver, and since then it’s definitely grown. It now works much better on devices running Android 5.0 Lollipop and the new Advanced Saving features that use the DU Aurora Engine are great additions. Being able to stop apps consuming battery in the background and also cut out the noise from unwanted notifications is great, and it really works quite well. I am still concerned with the idea that killing apps solves the battery problem we have on Android, but the power modes are still great. Being able to control these profiles with your own custom ones is great, and I still think this is the most helpful feature of the app. All-in-all, I was once again impressed with the wide array of features on offer here, and if you need to get the absolute most out of your Android devices’s battery, then look no further than DU Battery.


  • Speed (4/5) – DU Battery Saver runs nice and quickly and getting everything setup is super-quick.
  • Features (5/5) – With the new DU Aurora Engine, Notification Saving and Advanced Saving, DU Battery Saver is yt again packed with great features.
  • Theme (4/5) – The blue look and feel of the app is consistent, recognizable and the ability to theme the battery skin is a nice touch, too.
  • Overall (4.5/5) – Killing apps might not solve the greater problem, but with those Power Modes and the new DU Aurora Engine, DU Battery Saver can definitely get more out of your battery, and it also educates users to pay more attention to what’s going on on their smartphones.


  • New Advanced Saving and Notification Saving modes can help cut battery drain from apps that continue to run in the background.
  • Runs much better on devices running Android 5.0 and above.
  • Custom power modes allows users to tune their battery usage to their liking and make sure they have a device to use when they need it most.
  • One-tap operations for most tasks do a decent job for the majority of users.


  • “Toolbox” is basically a place to advertise games and apps.
  • Killing apps might not be the definitive answer to better battery life, but it will offer respite for a little while.

After spending some more time with DU Battery Saver after its considerable update I can say that they’ve added some great new features with the DU Aurora engine which makes it nice and easy to prevent apps in the background from continuing to suck up precious battery. The new power modes work well, and overall DU Battery Saver is still one of the best battery saver apps available on Android, and one that has just gotten much better in this big update.
