My Personal Experience

Let me come to the personal side of the app. The DU battery saver has been an instant hit with me. Actually, there were two apps (won’t like to mention it here) that were eating my battery for at least two months. It was very difficult to manage this as the battery was losing around 60% of the charge in around seven hours – from 2 am to 9am (without using the phone).


Due all the hectic daily activities it was getting impossible to diagnose the exact problem. However, two days back, I took this task on a war-footing, searched the app on Play Store, read some reviews and immediately installed it.

It didn’t take me long to realize that the DU battery saver is what I was looking for. I set the time after charging a bit. And I realized that the battery hadn’t lost even 1% in about 15-20 minutes. Another test I did was how much it lost in seven hours. After installation I found that for the same time period – 2 am to 9 am, it had lost only 4% of the charge.

Highlights of the App


There is an “Optimize” button on the home screen. Tapping it optimizes your phone to the best possible extent by stopping the power consumption of the apps running in the background.


It increases the life of the battery by healthy charging. So, the battery charges faster and remains in good condition.


With the help of the “Optimize” button in the DU battery saver, you can instantly find the problems with the battery consumption and find solutions.

Charge Mode

This afternoon, I did the last test. I had used the phone for a while and the charge dropped to 56%. Yes, the Fast Charge option is indeed fasssssssssst

Fast Charge

Uses constant current for performing fast charge up to 80 per cent. It is followed by healthy charging for getting the battery fully charged.

Full Charge

Reduces charge current when the battery is fully charged. It then uses the impulse current to charge the battery fully.

Trickle Charge

Trickle charge keeps the flow of the electrons in the battery. It makes up for the self-discharging for getting longer life.


Even after watching videos for more than five minutes, I had lost only 1% of the charging. The volume was at its peak on the MX Player. This simply shows that the DU battery saver is indeed the world’s No.1 battery saving app.
