16 tips and tricks to improve battery life on the Galaxy S7 and S7 edge

If you think about it, we've pretty much hit something of a ceiling with smartphones—at least in a way. Most of the hardware today has long since crossed the sanitary minimum required for a decent user experience, and previously exclusive tech is now available to the masses. So we have all the eye candy we want with the displays of our smartphones, we have all the processing muscle needed to keep things running smooth, and we have cameras good enough to capture most any moment without too much trouble. But there's one piece of tech that's been lagging behind the rest, and for as long as we can remember: battery.

Creating energy and storing it is a tough thing to do. You ought to know—just refer to your last month's electricity and gas bills, and consider the wood required to keep your swanky fireplace burning. Improvements are, of course, made as we go along. The batteries in the smartphones of today are better than the ones five years ago. And in five years, they'll probably be even better. The various components inside your smartphone are also becoming more energy-efficient. And yet, we want more.

Indeed, if there's one component that seems incredibly resilient to the law of diminishing returns from the point of view of users, it's got to be battery. The more of it we have, the better, and we sure want more. Loads more! And there are ways to get a better performance out of the juicer inside the phone your pocket, especially if it's a Samsung Galaxy S7 and S7 edge

We've compiled below a number of tricks and tips to improve battery life on Samsung's latest, and they range from rather obvious all the way to complex and time consuming. Nobody expects you to go for all of them. Instead, try and tailor these to your needs and preferences in order to get the best out of your battery without sacrificing functionality that you care about. After all, if you do end up with better battery life, but only at the expense of essential features, then what's the point?

This isnt really necessary on my Exynos S7 edge with 7.5 hours of screen on time on the regular...thicker phones with bigger batteries FTW!

Yeah, I got just under 6 hours of sot on a charge that lasted 2 days without any power saving modes activated so that's good for me.

With the GS5 and Note 4, one ('power user or not') could carry a few spare fully-charged batteries to get them through the day. This wouldn't matter.

TouchWiz + unoptimized SD810 = bad battery life and equally bad performance.

S7 easily best 6 and 6S and even 6+ and 6S+ on screen on time ( basically when you really use the phone ) So too bad for you!

Does anyone know the name of the theme in Slide 10?

I think its called TouchWiz Dark....I'm not sure

I came here to ask about this also. That theme looks perfect. I couldn't find one named "TouchWiz Dark" as mentioned before, but I found "Marshmallow_Dark", which is comparable and looks amazing also - I'm using it from now on.

First of all this article isn't about the G5 and..they already have..it's terrible. Usually I woul say don't need Phonearena's battery test but GSMarena says the same thing

G5 have removable battery, so you dont need such test... < maybe they think like this

10 should be: Go BLACK. "Dark" is not enough. AMOled switches pixels off when using BLACK. Dark only gives less eye strain when at night or in dark places.

"We find most of these silly, though we won't dictate what works for you." Thanks, that's very nice. Actually, I'm using those "silly gestures" on a daily basis, and it enables me to hit the screen of my smartphone to make it shut up when the alarm rings, every morning, instead of having to swipe a small button while I'm sleepy, for instance. Or I can silence a call by putting my smartphone face down on a table, instead of rejecting it, etc.
