Galaxy Note 9 battery life isn’t great, but it never leaves me worried

The Galaxy Note 9 hit retail stores worldwide in late August. Barring the two weeks of using the Galaxy A7 in between, the Galaxy Note 9 has been my daily driver for nearly two months at this point. The Galaxy Note 9’s 4,000 mAh battery was one of the biggest reasons I had been looking forward to its release, and I feel battery life on the phone isn’t as great as I had expected. But the Note 9 never leaves me worried, which is not something I can say for any other Samsung flagship since the Galaxy Note 4.

Galaxy Note 9 battery life ain’t great, but it’s dependable

I have been taking battery life screenshots at the end of each day for a couple of weeks now. And I noticed that I could always get at least four hours of screen on time and 14 hours of total time off the charger. On most days the phone would be sitting idle on a 4G connection for two hours or so as I played badminton; the rest were spent on my home’s Wi-Fi network, with two SIM cards active at all times. And I have to admit that it’s not the kind of performance I had expected from the 4,000 mAh battery, especially since it was mostly just moderate usage that didn’t involve a lot of browsing, video viewing or other heavy tasks on any given day.

But then the Galaxy Note 9 battery does have to power high-end hardware. Samsung’s newest Exynos chipset (the 9810) is based on the (albeit improved) 10 nm process that last year’s Exynos 8895 was built on as well, so it’s left to the higher battery capacity to improve things instead of major enhancements to efficiency under the hood. And it’s also worth mentioning that Note smartphones offer a few extra software features over the Galaxy S smartphones.

If I had to vote in our poll about Galaxy Note 9 battery life, I would select the “it’s good, but I expected more” option. Some of you might be wondering how I can have anything other than great battery life. Or how the screen time almost never seems to cross the 5-hour mark. That might be down to how battery life on Samsung phones seems to differ by country. Mobile networks here in India aren’t very optimized and using a flagship phone with two SIM cards also takes its toll. You can imagine what people in India go through with a Galaxy S9, then, with that measly 3,000 mAh battery.

Dependable battery life on a flagship is enough for me

But the Galaxy Note 9 almost never has me worried about running out of juice. That’s something I can happily live with, especially given how the Note 9 offers an excellent overall user experience as well. It may not be enough for everyone, but after years of seeing fast charging being offered as an alternative to long-lasting batteries, the Galaxy Note 9 is a breath of fresh air. Here’s hoping Samsung will continue to keep battery endurance a priority on future flagship Galaxies as well.

I get more than 3 days battery life on my Note 9, because i don’t usually use it more often.

seems many exynos note 9 users don’t get great battery life. there are some exceptions though. I have the snapdragon version and i consistently get great battery life. Ii’ve had 14h of SOT in one day a couple of times, but if i use my note 9 that much I always get 12h+ in one day. what is great since I’ve calmed down since the honeymoon period i easily get 2 days of battery off one charge, sometimes 3 days. my note 9 has a completely black wallpaper and many of my UI/UX elements are blacked out also. when I… Read more »

I’m getting 7 to 8 hours of SOT each day, wqhd mode and always on off. On less usage days my phone lasted two days or in YouTube days or working designing in sketchbook I’m getting 10 hours of SOT…. Battery is great for me, just as I expected or even more. Pretty happy with my device.

With only turned off AOD and no power savings, I got from my note 9 exynos atleast 8h SOT and 24h on battery. If I game a lot, like 2h and more, I still get 5h+ and 24h atleast. I guess your signal area is bad or/and you use the note 9 a lot more in boosted brightness mode?

Finally someone that says that the battery life should be better. Anyone who disagrees please check oneplus 6t’s battery life (i don’t like that phone but heck that software is optimized)

There are 2 methods to which you can improve the battery life of your Note9: Option 1 ======== I think there could be a small improvement, if you could apply a Dark Theme from the Samsung Theme Store. Additionally, if you use Substratum, non-root method via andromeda (paid app) and use Swift Black (paid app) theme, you would see a slight improvement. If you guys are planning to use substratum, please make sure you follow guided instructions. It’s little risky when playing with the options (follow an online guide or youtube tutorial), if the wrong options are selected it might… Read more »

It should be good already for a device that costs that much and that has a ginormous battery

Yup, It has to be.

I’m currently on Note8, the battery isn’t that impressive as the Note9.
Wish I could have waited a bit longer to get the Note9.

I guess next Note would be a huge leap.

I think it’s more than good! 5/6 hours of scree on! Sometimes I wonder if people has a life to use the smartphone more than 4 hours a day

If I don’t game I can easily get 8h SOT and 24+h on battery – facebook, messenger, youtube, viber, samsung internet browser. If I game for 2-3h heavy games, I end up with 5-6h SOT and 24+h on battery. The only thing I do is turned off AOD – never liked it and it drains quite a lot of battery.
