Show us your battery stats.... To see what's eating your battery..

845 version?

[Firoz110]

Same issue here, been at work all day and not used much at all. Screen on time is 2hours and down to under 30% got the the phone on optimised mode.

Here's a screen shot, I did put it on charge for a few mins right before I took the screen shot so you can probably see it going up. I knew I shouldn't have bought another samsung.

Anyone know what might be going wrong?

UK version s9 plus

[Shaquille Biffee]

Not an expert... But I mean it's supposed to be a 3500mah battery right?
Not good news at all...

[Firoz110]

Switching from a Google pixel first gen which had a 2700 mah had better battery life then this with similar usage to the above it would be around 50%

I knew I shouldn't have bought another samsung.

And yet!

The Pixel doesn't have 230 extra apps running in the background. I would highly advise anyone getting a samsung device to not expect great battery life because of the software. I'm not saying it can't be a great device and a great experience, but I would not expect great battery life. If it does happen I think its an anomaly and not then norm.

[dikonomi]

It seems a great device with a weak battery performance

[the mav]

just curious but what is the best display to have set for every day use? I'm new to Galaxy

[DamianP]

if you search on YouTube there are a bunch of new battery comparisons with the s9+. I'm consistently getting 5.5 to 6 hours of SoT on my Note 8. I have about 140 apps, ATT locked version. I disabled almost all the bloat. With AOD on standby loss of about 1% loss per hour. I would disagree that Samsung has general bad battery life . I have an Mate 9 as well to compare.

[LPRodgers]

Android system and Android OS @18% is insane, means rogue app....

[neo158]

Batteries take several charges to be conditioned properly anyway so bad battery life on a 3 day old phone is to be expected.

I have a SD845 S9+ (delivered today).. Battery seems to be very good. Don't have enough info on standby drain but don't see heavy drain. I did the following.
1) Setup from scratch.
2) After updating to the latest firmware I reset the phone
3) Disabled a few apps & Bixby, using BX Actions to remap bixby button
4) No AOD, no iris or facial scanning just the fingerprint sensor
5) Charged the phone after turning it on, setup the phone while plugged in.

I'm at 1hr 48 min usage 84% battery remaining. I used the phone for browsing and some apps here n there, set them up, not heavy usage. I know I'm happy that I am on the good side of battery (I OCD on battery usage :P ) and seeing stats like this would make someone who has bad battery go crazy, I'm posting this so that one could try these and see if the battery gets better.

Many purchase Samsung for its features. Now we are told to get decent battery life it is best to disable as many features as possible. If I wanted a featureless phone I would buy a Google phone in the first place. Older versions of Android would tell you which apps were using the battery. Now too many are included in "Android system" so we have no idea what is going on. This is a bad thing.

The real source of the problem imo are the changes in Android that prevent us seeing specifically which apps are eating the battery. This isn't Samsung's fault. I suspect providers prefer that users don't find their bloatware as a proven source of problems. Android now hides it nicely.

My s9 went from 100% battery to 35% within 8 hours normally it goes down to 70 or 80% within 8 hrs and mine is 6 days old

[pedrouliani]

My friend’s S9 goes from 100% to 30% in 9 hours, he said it’s pretty good and wouldn’t change anything about it

[illdini]

Disable features that you're not using (for example, I disabled Bixby & associated programs on my S8+).

[jako607]

This happened to me out of the box with my S7 Edge as well....FWIW I found that factory resetting it someone "jolted" the battery/OS into working properly and I never had a problem after that .

What version? Kind of hard to trend not knowing if 845 or 9810.

You can blame that on consumers wanting thinner devices (per consumed marketing). Aesthetics over practical useage.

I played with a "loaner S9+" today at work and it seemed like the battery life was quite good, better than my 9-day old Note 8s. I did disable/uninstall a lot of the bloat, but I always do that.

[manomic]

I was able to squeeze 7.5 hrs of SOT in 47 hours after the first charge. SD845.. 22 mins of calls, mostly browsing, didn't play a lot of videos.. took a few snaps and played around with AR emoji.. standby seems 3-4 hours/ 1%.

I don't use AOD, Bixby, Google Assistant & Iris / facial unlock. I'll use AOD if/when I get an update that makes AOD work with proximity sensor that allows me to wave and make the phone display the AOD content (like I used to have on my old Nokias). The rest not important for me.

My point being, I was able to get this much, so anything less in battery life would amount to what we use on the phone and how we use it like disabling Location, bluetooth , wifi etc when not needed.

[sqa4life]

I didn't read all responses, but I also noticed the battery life was not so great on my s9+ initially (on the first day), even thought I set it up as new device and reintalled all apps manually.

However, on the 2nd day, I decided to reset to factory and start fresh. To my surprised, the battery life is awesome now. I set the screen resolution to the highest and always display on as well.

I use the phone alot throughout the day.

Here's mine for today. Day 2. Much better then my Note 8. And this is heavy use. Downloading a ton of stuff. Phone calls. Lots of texts. And some light gaming. I think it can only improve. I dont remember the last time I got much over 3 hrs of SOT.

I found a couple of apps to tweak on my end to improve this as well. Hopefully it gets even better. Very happy so far.
