Don’t take it for granted that a smartphone’s battery can only last a couple of days. In this guide, I will show you how you can greatly extend the mileage you get out of your trusted sidekick. I’ve more-than-doubled the battery life of my Galaxy Note 3: my current record is 5 days, including quite a few phone calls and occasional browsing & gaming. True, the Note 3 has a large battery (3200 mAh compared to Galaxy S4 at 2800 mAh or iPhone 5s at 1560 mAh). If I’m conservative, I can easily get 8 days out of it! I don’t think I have to tell you how awesome it is to reduce your reliance on recharging, not to mention this prolongs the lifetime of the device’s battery.
Many of the energy-saving measures presented here rely on one of the most capable automation apps ever: Tasker. There’s a gazillion things you can do with it, and one of these is the ability to regulate the way your device uses mobile data, which is a serious power guzzler. If you truly want some amazing battery life improvements and are willing to invest a few hours in permanently advancing the quality of your mobile experience, I’m going to remove your (potential) fear of rooting your device and also tell you about how to use a custom kernel for further energy saving.
