DU Battery Saver PRO & Widgets

★★★★★ One of the best battery saver app.

★★★★★ ****Update 4/13/2018***** I seen that DU has finally updated to version 4.0.0 as of today. I have not installed but based upon previous experiences with this app it should be a good purchase for any user looking to extend their battery on pre-android 7 systems. *****Do not buy - Buyer Beware!!!!***** Most companies want you to buy their products. However, DU sees fit to promote their free Ad-supported version over this the PAID version. Proof: The Paid version was last updated on March 2, 2015 (over a year ago) and is on version 3.9.8. The Ad-supported version was last update on September 9, 2016, and is on version 4.2.6.3. Why would you pay for an outdated and apparently no longer updated software that has less features? Until this PAID version is updated to and and stays current with the Ad-supported version, I will keep this rating. If DU decides to again support the PAID version and keeps it current, I will then change my ratings. Additionally, they ask you to join the Beta program . I have asked to join that over 3 months now, and still have not been accepted. Again, this supports the belief they are not supporting their PAID version.

★★★★★ I noticed a saving right away. I tried the free version first and noticed more drain then gain. Uninstalled then bought the pro version and noticed a big difference. More options, well worth the 4$.

★★★★★ Months ago it really looked like I had no choice but to buy a new device, but I searched the app store one more time and after reading a couple of apps similar to this one, I installed your free DU app. I couldn't believe the difference it made for my device a nd ME! Thank you! After a couple of weeks I was so happy with it, I got the paid Pro version and today months later, I still feel very pleased with this app and want to say thank you, thank you, thank you!!! Financially wise I needed to wait until the end of summer to get a new phone, but with this app my phone runs like new, I also installed this DU app on my tablet and my husband also got this app for his tablet nd his phone. Again we want to say...thank you, thank you, THANK YOU FOR OFFERING THIS APP!

★★☆☆☆ Free version works far better than this paid version. No widgets does not optimize like free version. Advanced cleaning and Notification cleaning does not work. Does not shut down any apps. No real notifications of anything. Update this as much as you update free version. Paid version should work better than free not worse

★★☆☆☆ Warning Last update 2 may 2015. And free version update and paid app not update why plz paid app

★★☆☆☆ Pro Version을 설치했는데 왜 다른 DU 앱에서 10개의 앱이 켜져있다며 무료버전을 깔라 그러죠ㅋㅋㅋㅋ 왜 Pro Version은 아무것도 하는 일 없이 충전 다 됐다고 하는 기능밖에 없고 최적화된 앱 리스트에는 아무것도 없는걸까요.... 세계 최고의 배터리 앱은 무슨... 진짜 DU 너무 실망입니다...
