How to improve Galaxy S8 / S8+ battery life


Bigger screens. Faster processors. Batteries that are the same size (S8) or smaller (S8+) than their predecessors. It’s not surprising that critics and consumers alike are worried that the Galaxy S8 phones may have disappointing battery life. Thankfully, there are plenty of ways to improve your phone’s longevity, from software tweaks to hardware additions. Let’s take a look at some of the easiest and most effective ways to improve your Galaxy S8 / S8 Plus battery life!

Software tweaks

Find out which apps and features are using the most battery


Google added a very useful feature in Android Lollopop, and it remains indispensable to this day. Visit Settings > Battery, and you’ll find a handy list of apps and features (like the screen, Wi-Fi and your cellular connection), along with the amount of battery each of them is responsible for using.  Click on each entry on the list to fix the problem; e.g. by disabling or removing unwanted apps, turning down the screen brightness or disabling Wi-Fi.

Enable MID power saving mode

Samsung’s power saving mode returns with the Galaxy S8. You can enable it via SettingsBattery, or find it in the quick settings (drag down from the top of the screen twice to see the full range of options). You can choose to manually enable it, or have it come on automatically at a certain battery percentage level.

However it’s turned on, the effects are the same. Apps won’t be able to fetch data in the background, so you’ll need to have apps open to see incoming messages and notifications. However, texts and calls will be unaffected. Location services are also disabled, but these can be re-enabled manually if desired. Even vibrations will be kept to a minimum. The phone’s performance can also be limited to save additional power, so you may notice more stuttering or lag than usual.

Enable MAX power saving mode

If power saving mode isn’t strong enough, there’s only one place you can turn: MAX POWER SAVING MODE. Accessible in the same area as vanilla power saving mode, ultra power saving mode goes even further to limit your phone’s performance and eke the absolute maximum of battery life out of your phone. The display goes black-and-white, and all apps apart from Phone, Messages and Internet are disabled.

Disable the always-on display

The Galaxy S8 retains the same always-on display as its predecessor, and it’s unfortunately no more efficient this time around. It will drain between 0.5 and 1% of your battery per hour, or almost 25% in a full day, so it’s well worth disabling if you don’t need it or use it. You can find the toggle in Settings > Always-on display.

Hardware solutions

Use a power bank

One of the easiest ways to extend your phone’s battery life is to simply recharge on the go when you need to. Just pick up a power bank or portable charger in the size, shape and capacity of your choice. We recommend one of Samsung’s Adaptive Fast Chargers, as these will allow you to recharge much faster than with a traditional power bank. Huawei also make a Quick Charge 2.0 power bank that works well.

Use a battery case

Another good option would be to pick up a battery case: a case with a built-in battery pack, allowing you to augment the capacity of your smartphone with ease. However, battery cases haven’t yet been made for the Galaxy S8. If you’re reading this after mid-April 2017, then check out our range of S8 and S8+ battery cases below:
