Increase Battery Life by doing this. - Samsung Galaxy S8+ Questions & Answers

I have found out that samsung's App power monitor actually drains battery !
This is my normal drain .

This is app power monitor turned off (located in device management>Battery >3 dots>slider to off)

And does turning app power monitor off cause background applications to drain battery over time ? The answer is no.
Unplugged my phone at 100% with 20 apps opened in the background .Woke up the next morning seeing 3% battery drain only. (whatsapp msg led was blinking all night too )

Few people at the S8/S8+ group on whatsapp did say it improved their sot/standby abit.

Do you have anything else tweaked? Are you using any package disablers?

Wifi is draining power

Hy
My asus is working fine, but when I let my Wifi on and have my dock attached I lose 10% in 12 hours
Can anyone help me with a few ideas?
Thanks guys
Gesendet von meinem Galaxy Nexus mit Tapatalk
i simply turn off the wifi when im not going to be usung it for a while. it uses a lot of Push data delivery systems so thats why i think it would drain as quick as it does..
thats crazy! I'm having a similar problem, i turn on my screen and it seems to lose power faster than when i don't have it on!!!!
Whatever could my problem be!

You are funny, and I am sorry
It's losing power while I turned it off or better I put it to sleep and it still using lots of power without doing anything
I hope that is a little bit better?

Like I said.. simple solution, disable the wifi. Or change the apps to not Push or to pull for updates over longer time intervals so reduce the ti,e wifi needs to stay connected in the background. when I've just disabled wifi the battery drain is next to nothing.
EDIT: There is also the option to auto-disable wifi when the screen is off in the settings

Ok cool, if you want, let me know how it goes. There's other options as well. They just take more micromanagement/setup

Power manager service sucks my battery

Hi, since a few days ago, a battery drain started to appear, the phone is almost always awake and no deepsleep. In the settings menu it shows that Android system is responsible, and batterystats says powermanagerservice...
So where can I find this service, and investigate what went wrong all of a sudden. Didn't have such problems before, and only changes are I started to use the network localisation service(without wifi) and had viber, which i just removed.
Any ideas how to fix?

if you are rooted you can get rid of this power management thing.
you can delete the htcpowermanagement.apk/odex in system/apps.
This is the easiest thing to do. But i want to find out the reason of this sudden misbehaviour. Thanks.

strange. did you tried a factory reset?
I still hope to avoid it
I think of getting some log info, when this happens again. This morning, after unplugging the charger, just checked mail, browsing and tapatalk, and the phone remained awake. Now sleeps like a baby, but already lost 10% from this, and the cpu was stuck at 300mhz during the awake period...

Anyone out there who have issues with mediaserver draining too much battery? Last night i charged my phone till it reach 90% then i wake up and it dropped at 72%. When i checked the battery usage in settings, mediaserver is 6 hrs kept awake.. also in GSam, mediaserver is responsible with the drain. I know i've read somewhere here in One S forum about this but i couldn't find the exact thread.. does it have a fix? Thank you.

If you have viber, uninstall it. There are tricks to fix that, but are annoying. Waiting for update.

Phone suddenly dead. Can anybody help?

I was already noticing that my battery was starting to drain faster than usual, but yesterday it completely died. The battery said it was 100%, as soon as I unplugged it it was 0%, and then it wouldn't charge anymore.
This morning I replaced the battery with one that was confirmed working, it wouldn't turn on. I connected the charger and it went into an infinite reboot loop, it would show the battery charge screen with the battery and a loading circle on it. And then reboot, repeating this all the time. I haven't tried putting the original battery back.
I am now at school, but does anybody have any idea what's going on?
Greetz, Dominique.

Maybe change battery. You can use battery from normal SII

Wifi doesn't turn off even "Keep wifi on during sleep" = "Never"

Hi all,
I have set "Keep wifi on during sleep" = "Never". But when I turn off screen or sleep over night, Wifi is always on.
Attached the screen shot from GSAM battery, Doze mode is active, "Keep wifi on during sleep" = "Never", but Wifi still on. This takes away 10% of my battery over night.
Does anyone get this problem?
maybe you have an app keeping WiFi on? this works for my s7...
Same is happening with my galaxy S7 edge. Are you rooted ?
Just noticed same happens to my s7 edge. European model, no root.
Yeah. It happened after the new PD1 update. You can just forget the network and add it. It seemed to fix it for me

Go to Settings, Location, there's a menu called Improve Accuracy (ίσως βελτιστοποίηση στα Ελληνικά) and it allows the WiFi and Bluetooth to keep scanning even when off. Disable this feature and you should be fine.

Is for turning off wifi when the phone goes to sleep mode, most of the times this happens after some minutes after you turn off the screen provided phone hasn't any task to do.

But mobile data consume more battery than wifi, so what's the point to disable wifi during standby? I just want to understand

Yeah I also thinking of that but i'am not so sure that is a fact. Why in the first place then exist this option, if you go for wifi always on it says it consumes more battery, if you go for mobile data it says consumes more data. If someone knows more about about this I would like to learn it also.

I think it depends on the network coverage in the area you are at any particular time. For example, at my old house coverage was pretty abysmal, so if I had mobile data turned on the battery drained like crazy. WiFi was a more stable connection as it only depended on a router a few metres away that for the most part worked as it should.

So, are you saying that in a good cover area the "wifi active in standby = never" is useful?
Because if you don't use wifi when the screen is off, you will use mobile data anyway. So where is the "saving"?

It really depends. For example, some people are on contracts with limited mobile data, so they want to use wifi as much as possible. In terms of battery consumption, I don't think there's a huge difference, apart from when in extreme circumstances, like a low signal area, as I mentioned above.

Battery fading

Within the last two months, same setup and even after full resets, I have gone from getting max 20% a day loss to 30-40% loss.
My S3 is about a year old I tend to charge when around 15 to 20% left.
Anyone finding finding similar?

I think I isolated my issue, it's that stupid Samsung Pay, doesn't show in the usage as high but recall since installing (app is waste for me as bank does not support) I lose 1 day battery life.

Add me to the list. It's infuriating I've tried everything. I'm now running the simplest, darkest watch face I can find to see if that helps.
