Improve the battery life on the Samsung Galaxy Note 8 with these 17 tips and tricks

The Galaxy Note 8 is the hottest new Samsung super-phone in town. This handset is the latest representative of the company's new design approach which emphasizes on keeping the displays big and bezels small. 

The results from this philosophy are quite impressive - the latest Note packs a massive 6.3-inch panel at the front which is easily one of the largest screens we've seen on a high-end smartphone to date. The majority of its specs and features are equally awe-inspiring: the powerful Snapdragon 835 chipset, an advanced dual-camera composition, loads of RAM, and a new and more precise S-Pen. 

However, the Galaxy Note 8 does have one key area that isn't all that breathtaking - the battery. Its 3,300 mAh capacity would have been more than enough for many other mobile devices, but it does look a bit underwhelming for a phablet of this stature. Of course, there's a very good reason for that - Samsung tried to cram a 3,500mAh cell in the Note 7, and we all know how that ended. Still, let's take a look at the numbers before we jump to conclusions. 

Battery life (hours) Higher is better
LG G6 6h 9 min (Average)
Google Pixel XL 7h 19 min (Good)
Samsung Galaxy Note 8 7h 50 min (Good)
Samsung Galaxy S8+ 8h (Excellent)
Sony Xperia XZ Premium 8h 15 min (Excellent)
Apple iPhone 7 Plus 9h 5 min (Excellent)
OnePlus 5 9h 18 min (Excellent)

The Note 8 clocked in at 7 hours and 50 minutes in our custom battery test. That's better than the LG G6 and the Pixel XL, but the iPhone 7 Plus, OnePlus 5, Sony Xperia XZ Premium, and Galaxy S8+ all performed better in this department. Overall, one might argue that the score is decent and that we're nitpicking a bit here. However, we have to remember that this phone costs nearly $1,000, so more should be expected of it. 

Odds are that the Note 8 will be able to last through a busy day, but what can you do if you'd like to get even more time between charges? 

Below, we've compiled a number of tricks and tips that will improve the battery life on Samsung's latest and greatest. Some of them are rather obvious, others - not so much.

Nobody expects you to adopt all of them as they include turning certain functionalities off, but you can test them out and decide what works for you. A good rule of thumb here is: If one of the methods takes away features that you consider essential, just don't bother using it. With no further ado, let's see what's on the list.

Yeah, turn off everything that makes a smartphone smart. Instead we could simply provide feedback in lower review scores, because of the weaker battery life in newer generations of devices. Even Note 4 has a better battery life. A 3 years old device! What a great leap in innovation we made!

I haven't turn off anything except Bixby button, and I turned on things that were off by default. I still get 2 full working days on a single charge The Note 8 has great battery-life, except to people who don't actually use or have one for anything other than to write articles and lame reviews.

Yep, totally agree. They have really optimized the software to improve battery life on the note 8. I get atleast 1.5 days on a single charge. There are tests done in other sites which clearly shows note 8 has a better battery life. All of them who complain have not actually used it and just going by the capacity reported in these sites.

how are you getting 2 days? i am using accu battery and it says ~24 to 25 hrs with SOT and sleep combined and i can see from my daily use too. i think 2 days is over stretched.

Nah, just presstitutes trying their best to downplay the successful non-apple competition with asinine lies and BS. Just search Note 8 battery life test on YouTube and see all the comparisons contradicting the BS on this site.

FACT - PA's battery test have been purposely flawed to make the iPhone seem to have better battery-life, when in no one else's test on the internet gets such low numbers on the battery. PhoneArena is bias towards the iPhone and rigs any battery or camera test, so that it favors the iPhone. Facts online everywhere show the Note 8 actually outlasting the S8+, just like there were tests showing the Note 7 outlasting the S7 edge, even though in both cases of the Note 7 and 8, the battery was smaller than the S model. So I have been using my Note 8 since 9/6. For the first few days I was using it very heavy, seeing what has changed, getting everything set back up and testing out apps and stuff. Saturday I gave it my biggest battery test. ZI took a 100mile bike ride. I rode from house in Chicago to Elgin IL which is 40 miles one way and then I rode back home via a different route which was 30 miles to go back east and then another 30ish straight south. Total ride was 103 miles. I had 2 mapping apps going which means GPS was always going which normally consumes a lot of battery, and recording 4K video. The apps are MapmyRide and Strava. Now I did a similar ride with my iPhone 7 plus. Same 2 apps, same camera recording 4k video from my house to Six Flags which is 48 miles one way. The iPhone 7 for just 48 miles has lost 70% of its charge. My Note 7 lost 60% of its charge. My S8 Plus on a similar ride lost 67% of its charge. My Note 8 in 40 miles which took me 2.5hrs lost 62% of its charge. I always turn off the camera for the ride home, just in case I break down and I need to call for a ride/UBER. But the mapping apps are still going, I simply turn off the camera. My iPhone 7 on a 100 mile ride, died 2 hours into the ride home. My Note 7 even after I got home still has 15-20% of its charge left. My S8+ also had 25% of its charge left. My Note 8 had 27% of its charge left. This is how much charge is left when I pull up to my door and turn off the apps. These apps auto-pause and start when I stop and go. GPS I know is a strain on the modems. This is leaving all phones on whatever settings they are normally on. Now, I though my Note 8 wouldn't last the whole ride so I brought my spare Samsung 5000MAH battery just in case. But I ended up not needing it. The 256GB iPhone before taxes is $969, or about $1070 or so with taxes. It gets even worse battery life. Curious if you've ever said the same?!

So you're suggesting to turn off half the features that I payed my hard earned money for just to get a couple minutes extra juice? Money wasted down the drain.

Yes and congratulations for wasting money on flagships. There are other midrange smartphones with battery life miles ahead of any of those compared here.

You should turn off features of a phone that you don't use that could be a battery drain. I mean, just because your phone has a ton of bells and whistles, doesn't mean you should have them on all the time. Example - When you arent using WiFi, do you leave it on? If so...why? Its draining battery even if its not being used. What about BT? What about the display? Do you have it on when you're not using? Of course not because it turns off automatically. But the other stuff doesn't. I personally always turn off WiFi when its not begin used. Its not money wasted. Turn on a feature only when you need it is called being smart. But dummies like you who buy featureless phones, why do you even care? Do you own a Galaxy device? No! So really your opinion doesn't matter.

According to PA, the Note 8 has "Good" battery life, so you don't need another phone. FACT - no matter what phone you buy, if you use your phone a lot, especially to talk or heavy internet usage, you should invest in a phone with a large battery and less features. But that isn't how people whop. They buy what is popular or eye-catching, don;t read the specs and then complain later. Once I go back to normal usage, my Note 8 will last to full work days on a single charge. Even if it don't, it won't matter. I have a charger at my desk, in my car and at home and everywhere else I go I can charge it too.

Exactly if Apple made a smaller battery last longer on a bigger display phone they would be called genius Samsung does it and pa uses the only test a iphone can win. Watch this test change when the OLED Iphone comes out :)

Battery life is extremely variable, depending on what you're doing. Pretty much every other battery test out there has the Note 8 beating the S8+ by a bit, and both beating the iPhone. Look at them all as an average to get an idea.

Get the best battery life, don't buy it.

All my past Samsung phones had very bad battery life except the Note 7. The Note 7 was the only Samsung phone that can last me through the day. I was hoping the Note 8 would improve upon the Note 7. Sigh...

If PA tested the Note 8 at its native 1440p resolution, instead of a reduced 1080p resolution, the phone will probably last only 5 hours, whereas other 1440p android flagships such as the HTC U11 last 9+ hours. But PA being a Samsung supporter would never give us such a fair review that would end up making Samsung look bad.

Turn the phone to Ultra Power Saving mode instead

It's very wise to get a flagship smartphone with fastest chipset and turn off most of the features to conserve battery. You only need to switch it on when you want to brag about it to your friends, it's called "flagship smartphone syndrome".
