    Pretty disappointed in my S9 battery life. Using on AT&T and coming from a Pixel 2. Took the phone off of the charger 4 hours ago and already at 65%.

    I'm quite happy with mine(S9 845 At&t) Fully charged last night & I haven't used my phone much this morning but our SOT is similar.

    AT&T here I can go two days, maybe do a clean reset from new and make sure you're not double syncing, there. is a lot of useless syncing on this phone. Disable the Samsung cloud and Google cloud and go into Google and all your social media apps and see what's on for permissions (like location). I'm using Facebook lite and messenger lite and, disabled all the bs permissions they ask for in settings and that changed the phone for me quite a bit. You really have to tweak things on this phone from stock to get it just right. Disable the games and AT&T bloatware in settings is another tip I could give you. You could also download package disabler and completely turn off apps you don't want running. In battery settings you could also go add sleeping apps that you don't want notifications on and turn them off so they only work when you open them. I don't like a lot of notifications so I turn a lot of apps off and the phone is nice and quiet and I get what's important.

    I’m very disappointed in battery life on my s9 compared to my iPhone X. Yeah I know I could get better battery life by going Plus but I like the 5.8” form factor. I think the s9 battery life is poor to be honest.

    Check your mobile signal strength. Aside from the screen, the largest battery consumer is the radio transmitter when the signal from the tower is weak. (If the signal from the tower is weak, the phone transmits at full power to get a better signal to the tower.) A strong signal (around 90dbm) will result in a longer battery life. (Which can mean that you need a different carrier.)

    The point is, I'm using my S9 exactly how I used my Pixel 2. Same locations etc. The battery performance is just not great especially since the S9 battery is larger than the Pixel 2's.

    Review in general state the S9+ has similar battery life as the S8+, but the S9 is almost an hour less overall than the S8. Even some reviewers admit it seems odd.

    It's a new device. Let the battery get a few cycles and get conditioned.

    It takes a few days to settle in.... Or do a couple 100 to 1-2% cycles like I did

    I noticed battery life on my ATT S9 was not as good as my S8 also. There was an update I installed yesterday as well. Not sure what fixes were in it.

    i expect battery life to be crap when the phone is new, setting it up and downloading all my apps and just generally playing around with the phone will take a toll on it. I use both iphones and android phones, the iphones just do a better job at trickling battery usage when the phone is idle.

    My battery hasn't been well...it's definitely lasting longer then my 1 yr old lg g6 but I haven't been able to reach above like 4 hours screen time...usually occasional FB and maybe a game here or there but mostly text...most all my apps are asleep...I noticed when I take it off the charger the battery drops at least 5% fairly quickly maybe I'll do a factory reset already

    Disable all of the At&t crap you don't use too. I'm sure that's not helping.

    MKBHD just came out with his S9+ review and he said the battery life wasn't very good on the device. That's disconcerting because the battery life on the S8+ was great.

    Problem with listening to reviewers is you never know how they use their device. For me I get better battery life on my 9 plus than any other device I've had as of late. And that includes the Note 8, S8 plus, iPhone x and iPhone 8 plus. I'm averaging 6 hrs of SOT which for me the highest I've normally been able to get is around 4. So for me its amazing. You can't go off what reviewers say. It's just how something did for them or what their opinion is. He's a great reviewer for sure but I like to see for myself because everyone's mileage will vary.

    Yes, everyone's mileage will vary, but he told everyone what he uses his device for.

    Does the S9 have good background app controls? On my Mate 9, I can turn off background processing and autolaunch on an app by app basis. I find it helps with certain apps.

    I didn't watch it but I always start fresh. Especially when moving from a lower OS to a upgraded one. For me it's less of a chance some rogue thing will happen when coping data.
