My 3 day old S9+ Battery Drain Fast

[rushmore]

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.

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.

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.

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.

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

Ya I agree. I have over 60 packages disabled ranging from Samsung stuff to Gmail, to Yahoo, Bixby and others. I have always used BK package disabler for Samsung on Samsung devices.

FYI: Going on the third day with the phone, the battery is about done with the calibrating I believe, and it is performing to my needs and beyond. So far has gone over 24 hrs each day without needing the charger.

My wife's S9+ runs all day without any battery issues. But she is not a fan of the edge screen, so that's turned off.

I went yesterday and today, no charger and it went dead in 47 hours with about 3.5 hrs SOT, just insane battery life. I'm really cautious about what's syncing tho...

With power save(FHD+, slowing cpu etc.) mode my battery drain %9 in 35 minute.

Same here. I took delivery of my S9+ 48 hours ago. The battery life was about 3 hours compared to an hour and a half yesterday. It took 2/3 hours to charge last night so most likely it's still conditioning. I've heard that if it's on contract, wiping it helps the battery a lot. Mine is on contract so I'm going to try wipe it and see how that goes tomorrow, I presume the samsung manager will remove unseeable (to the user) Optus bloatware. Hopefully by monday the weekend the battery will have finished 'conditioning' and all will be swell. Fingers crossed.

I get 28 to 30 hours plus battery life. With 5 to 6 hours screen on time. I've disabled nothing. fully utilize all features including Always On screen. loving this phone battery life!
