- DU Battery Saver & Fast Charge
What it is:
Another “battery-saving” app with an insane number of downloads. It has 7.6 million five-star reviews. Well, sorry, but all of those 7.6 million people are wrong
Why it’s bad:
Fast Charge? An app does not have the ability to change how fast your device charges. This is also the king of adverts – it sponsors almost every ad that you see in any other app and manifests its own ads on your lock screen and notifications bar. Also, all those fancy speed graphs and cool animations? Totally fake.
What you should use instead:
If you’re genuinely interested in your phone’s battery stats, you should use GSM Battery Monitor. For proper battery saving, try the aforementioned Greenify.
