[Q] Battery Depleting Quickly

I have had my Note 8 for a couple of months and just recently I have been having battery problems. I restored the Note 8 to factory settings (just to be sure) and am still having the same problem.
It seems that when I watch videos or play any games the battery depletes extremely quickly e.g Its 80%, I start to play the game and within 3-5 minutes the battery is 30%. I play again and its 5% and the screen dims (which is also a pain in the ....) I realise that Games and Apps use a lot of power but surely not this much.
I have looked around for battery calibration instructions and apps but are a bit dubious to try them as I have read that you can deplete the battery totally and the device then wont charge.
Just wondered if anybody else has had the same problem.
Thanks.

My note has a great battery life. For this situation I would look in the battery menu for any apps not closing correctly thus sucking battery. Remember to dis activate GPS, Bluetooth and data when not using them. Check the screen brightness is 50% or less. Automatic brightness should be fine also.
here's a lot of info related to batteries. I'm sure you will find it usefull

Don't waste time with calibration. Sounds like the battery ifs failing or dying, either way it's bad.

I usually have Bluetooth and GPS turned off and have the screen on Auto Brightness. I also restored to factory and the problem still persists.
One strange thing is that when I charge it from 10% it takes about 50 minutes to get to 100%. I thought that was a bit quick. The battery must be reporting the wrong charge to the OS. I wish they had user replaceable batteries in this thing although its probably not practical.
I will give Samsung a call. Cannot beleive it has happened now as I am off on holiday soon to the US and wanted to use it there.
Thanks.

Hi, I've had the same issue. I sent the device for service under warranty and they could not find a fault. They only reflashed the firmware.
Its been working fine since I got it back. I updated to 4.2.2 and its working just fine.

same with me chas0001, and JCUK89, my situation is actually identical to chas0001, but my device is like a mth old now, i received it on august 5th 2013,
so its basically been used for jus over a mth now. and i barely use it, maybe 3 hrs a day, most days less than 1 hr, constant use.
i dont kno, can anyone help. on xda developers. ??

I called Amazon.co.uk (where I bought it from) and they agreed to replace it for me. Its was definitely faulty and unusable. I kept reading about people with the similar problems and so eventually decided to not get a replacement but a refund.
Its a shame really. I really liked the device but I need something more reliable. I also don't care for Samsung with their constantly delayed OS updates. 4.1.2 for a 'flagship' device. Surely if they get rid of that Touchwiz crap they can release timely updates. You never know even my Note 2 may get an OS update this year!
Just went out and bought a Nexus 7 (2013). NOW...what to do with those 5 Galaxy Note 8 cases

I would see of you can get it exchanged (assuming you still want to keep the device).

Replacement Note battery life totally sucks?

I ported everything back and I use Disabler pro, so I have a good list of stuff off like FB. getting 1.5 hours SOT for 100% to 30%

Try to just do a hrd reset and don't restore anything. i have the FD variant, and i'm hacing 4 to 5 hrs SOT

If you have a problem take it back and get it sorted.
I, to date, have not had a problem with either of my devices. IF one comes be assured it will be going back. 1.5 hours SOT is absurd. Ensure that the situation is not of your own doing then take it back.
Let us know how you get on. :good:

Return it, it's not the norm. I constantly get 5-6 hours with wifi, bluetooth, location (power savings) all on. I use package disabler pro to debloat and screen auto brightness. You may have a rough app.

i would take it back....the battery on my replacement has been much better then the original

Man setting it up all again is just a headache. I used smart switch so i dont see what the problem would be. I am doing a final test today to see how it goes. then ill decide. Ill do a cache reset.

Did you use Smart Switch to migrate to your new phone? Some apps don't like to be transferred. I used Smart Switch to move from my Note5>Note7 and it went fine. With the exception of any apps that work through Android Auto which I had to uninstall/reinstall. When I used Smart Switch to go from Note7>Note7 I've noticed really high Android System usage compared to my original Note7 which was set up identically. I'm going to do a hard reset and rebuild my phone from scratch over the weekend. And like @mrloootz said it's a royal pain in the a$s. For those that went from one Note7 to another and are experiencing funkiness it has got to be s/w. The h/w is what it is meaning h/w alone couldn't be so different from one device to another to cause different performance or battery life.

Exactly! everyone that have a bad battery on N7 have Android system first in battery stats... Screen on Time should always be nr1 if smth takes it place you have a draining app...

same apps i dint change stuff. i use package disabler pro as well to get rid of misc like facebook

when using smart switch does it copy the games and where you are at in the level to?

Im am having similar problems. 7 % battery drain per hour without doing anything.
The first three days with my new note 7 went fine. I got the update with the green battery and hat 6-8 hours SOT. Then yesterday I suffered from hourly 7% drain.
"system-server" seems to be the service that drains the battery.
Does anyone has a solution for this problem?
P.S. I already wiped cache, restartet the phone and froze several apps like facebook or Gear VR service. Nothing helped.

Please Search for "Oculus Android Battery drain" on Google.
"Apparently, the problem is with a new part of Oculus VR known as Oculus Rooms. The Oculus VR app is getting stuck in an installation loop where it continuously downloads and reinstalls this app. You'll be able to reinstall Oculus VR once a hotfix rolls out to everyone, but removing the app is probably your best course of action right now."
Gesendet von meinem SM-N930F mit Tapatalk

Thanks for your answer. I have never installed this Oculus Room app and I never ever used a Gear Vr.
Apart from this I already have frozen all Gear VR services with package disabler pro.
Still this system_server service drains 7% per hour

Wow that's not good. I would go see the outlet where I made the purchase and see what they can do with it. Sounds like an app but??? Mine is working great, if it wasn't it would be going back, enough already!

Oh well Samsung online Shop...
My first was running like a charm...
Gesendet von meinem SM-N930F mit Tapatalk

Hmm, I didn't use smart switch. Reinstalled all the apps and restored launcher screen layout with nova launcher restore function.
Installed package disabler and use greenify.
Upon exchanging phone, From the initial 51% charge, i used it until 40% and charged to 100 when I got home.
From full charge, it's now 3 hours and 24 min SOT with 39% left. Not bad I guess.

I have to say my battery life is actually better on my replacement! I also took a lot of people's advice here and did a complete reinstall of my device from scratch rather than using the smart switch or any other restore option. It was a pain to do but I think ultimately it's more stable and less likely to experience battery drain.
.

Reset fixed the Problem.
Gesendet von meinem SM-N930F mit Tapatalk

Well here are my stats. I think like everyone says start from scratch no smart switch no back up restores n it should give a good battery life.

Mine was running hot and slow charging as well as draining shockingly fast. Media server was top on my list at 44%. Some digging found this https://productforums.google.com/forum/m/#!topic/chrome/EJSiLeWiN7Q
I'm note using the beta version of chrome and it's all good. May not be the same thing but don't give up

Terrible battery life?

Does any one else get terrible battery life on their Note 7? I get on average 10-13 hrs of battery life, with around 3-4 hours of SOT. I noticed that my android os and android system are usually running around 20 and 30 percent respectively. If you guys have any thoughts or are experiencing similar results any advice would help. Thanks.

Yeah I am getting this too

I'm also getting this. It's incredibly frustrating as I've tried disabling everything and we can't figure out why

since last week i been getting the same and i'm pretty sure its an app that i d/l'ed bc i added a couple since then...

If you use Maps it drains a crap ton, which I think there is something wrong with it on Note 7.

I called Verizon and they are going to send me a replacement device since this is still under my 14 day return window. Hopefully that may change things but who knows. They also mentioned something about having occulus apps installed will drain battery but I don't have any of that. My old Note 4 was great and this Note 7 is fantastic but does not live up to the "Note" standard of battery life I've come to know and love.

That sucks guys I'm getting 6 to 6 and half hours of screen on time and I'm beyond surprised @ how incredible this battery is..

Ditto. 6 plus everyday. Actually better than my first.

Everytime I try to call them and ask for a replacement they always tell me to go to the store so I can get a brand new device instead of a certified like new. ?

Screen on time may not be a great way to judge battery life. You need a breakdown of everything using the battery. Different apps will use different amounts of battery and even the same apps like chrome will be different person to person cause of browsing habits. It all depends what you do on your phone.

Would you mind sharing a couple things like screen brightness, if you use maps, what services are on, if you listen to music, and how much of a power user you are? I am also getting around 3-4 hours of screen on time and would love to get 6.
Thanks

Same for me battery life ia horrible. And the phone is slow

With Bluetooth (fit2) and locations On and brightness on auto, wifi on, sound on vibrate, did some YouTube, Facebook, Instagram. My battery is doing much better than original so far.

Replaced my 7 with the 5.. And getting good battery life so far. This is just another option for those that may still need the pen..
From note 5.. rip note 7

Impressive. I didn't know the note 5 got that much screen on time. I range anywhere from 6-9 on my note 7. Does the note 5 feel that much diff than the 7? I'm going to guess it doesn't have the always on screen. I've really become used to that.

Actually, it's not that bad.. I didn't know it was possible either to be honest.. I just set it up like the 7, and this is what I received.. The battery life is so far seeming to be much like the note 7 for me.
It feels a little heavier in the hand, and wider.. It doesn't give that "ultimate" comfort in the hand like the 7 did, but it's surprisingly comfortable.. Much more so than I thought..
And lol, yes, it actually does have the always on display. It received it in the marshmallow update.. To be honest, from what I can tell so far, the only things major it does not have, are, of course micro slot(this one sucks, but there are tiny micro usb adapters for cheap), the iris scanner(i actually loved this, but oh well), the GIF feature of screen capture(i hope they incorporate that, at some point), and that's pretty much it.. Oh, and of course the edge and no secure folder. But I'm hoping, because of this fiasco, they will roll some of the software features from the 7 to the 5, like the GIF and secure folder.. Not to mention, bring back the eraser function of the pen like it originally was on the notes, and that they incorporated into the 7.
There are indeed a few sacrifices to it that I've discovered in my first couple days of owning it. But nothing that would make me want to go to a non pen s7 or edge.. It even has the pro camera features.. So I'm pretty good and settled actually with it.. I've got my gear 2 paired with it, and functioning normally, all my s notes.. And it's cheaper than the 7.. Now I'm not going to hardly say it's a 7, but at this point, we don't have a choice(unless your going to just try to hold on to your 7 for dear life)..
But it's a very decent alternative to be honest.. It really is..

SOT seems up to 2 hours less on exynos chip

I hope I'm wrong but looking at all the forums samsung have really let us down on the exynos chip... Can we c omplain or just wait a ND hope that they sort it out for us

Evrey user gets particular results, I have seen these varying results from the same type of device many, many times, since the days of the note 3, I recall the case of the note 8, there were people claiming absolutely insane SOT numbers, and others extremely low figures

I have the Note 10 plus with Exynos chip and my battery life is great! I had over 2days standby with just over 8 hours of screen on time yesterday! Granted, i do have background data turned off for alot of apps i dont use and i have disabled some apps etc but brightness is on auto and iam using the default theme as oppose to night mode! Iam very happy with mine! Battery life is one of those things that seems to vary massively between people for some reason! I would say the battery is marginally better then the S10 plus and the S10 plus was great!

Out of all my phones, the note 10 plus is the only one that gets me past 5 hours. I got more than 6 hours yesterday.
My old phones average less than 4 hours
Note 8
Lg v20
Note 4
Etc

Now that I have used my note10+ for 4 days, I can say that the battery is really good! I am getting 7+ hrs SOT

Power management may be causing issues for exynos variants; this happens on the snapdragon variant.
First week it seems ok with battery usage then boom, it goes hog wild nuts... happens every reload.
This may help those with unrooted Note 10's
I get best life if I let Android manage power management completely.
-Avoid using all 3rd party power management apps including Samsung's-
If you start manually setting apps to sleep it can cause increased battery usage; counterintuitive.
Bloatware and Google Transport are also the usual prime suspects.
Samsung Cloud Storage is another; package block* it.
Kill all Samsung, Goggle and carrier feedback.
Package block all carrier apps unless your really need them.
Package block Samsung push and all Knox crapware.
KLMS will still run though; turn off in running processes in demo mode.
Do not use a package blocker to kill Google Transport; simple turn it off. It's dependencies will constantly try to poll it if you use a package blockler on it... and kill battery life.
Clear data on Google transport, framework and Play Services as needed to curb Google transport usage.
Use the factory loaded Samsung Device Manager to clear app caches.
If AOD is on Google Transport brattery usage may be erroneously reported**when screen is off at about 1% every 6 hours; this is normal.
Goggle Transport should stay >1% during SOT.
Use **Gallaxy Labs Battery Tracker to keep an eye on power usage.
Turn off wifi and bluetooth if not using.

Battery draining like flies dropping dead on my brand new S20+ 5G Exynos..!! Any Help?

Recently bought a brand new S20+ 5G Exynos and it's running the latest March Security Patch update for Android 11. Problem is, after successfully rooting and killing off some of the ****ty bloatware that Samsung is obsessed to ship with it's Smartphones like Bixby, Samsung cloud, samsung games, pass, and much much more, my S20+ is losing single digit after every few minutes of just bare minimum usage like Browsing through apps, opening a simple utility or app or just wandering through the Settings Menu. I said it BARE MINIMUM since these activities do not cost so much pressure on the battery as running videos, games, installing and deleting and things alike. As I said, I turned off all the unncessary things like GPS, Display Brightness set to almost 20-30%, using BREVENT to keep all the background memory clear off of the background apps. I am not running any games, videos for that matter but my battery consistently losing a digit after every 8 mins I would say on these bare minimum activities. Sometimes even opening the screen and just scrolling through the app drawer drops 2 digits within 10 minutes. I set the display pixels to the lowest minimum and also disable the 125 Hz display smoothness effect.
I read in some posts that since Android 11, many users complained about constant and persisting battery drainage across multiple smartphone brands including Google Pixel users..
I am thinking of reverting back to Android 10 for my S20+. What do you people suggest?

As I said, nothing special in the Battery Usage as well. All the main components like Display and other multiple core system services are hardly using 2% and below.

if you used a backup to setup the phone (smart switch etc) this can cause battery drain. this is my personal experience. if you dont have 5g in your area disable it aswell.

I did not use Smart Switch. It came fresh out of the box. My brother sent it to me from Saudi Arabia. I just reflashed it with the Android 11 KSA Stock Rom and simply rooted it. Also disable Bixby **** and other unwanted Sammy Bloatware.
Yes, I do not have 5G currently in my area and my country as a whole except some 5G Trials.
How to disable 5G???
BTW I charged my Phone and I turned WIFI OFF. It just stayed there and I picked up the phone and just opened it and just used it for a couple of seconds and the battery came down from 99 to 97% on just simple Unlock and simple APP DRAWER browsing with WIFI Being off all this time.
Then I just opened the camera and took a couple of selfie shots and battery came down from 96% to 94% in just 2 mins. WiFi is still off. Only Sim card is active.

has to be some service that you disabled that is needed for some other sh** from Samsung.
If I were you, I would start all again, flashing the rom, test it without rooting it... see how much is the battery drain like that.... Try that method for removing the apps thru ADB connection without root, it works (search it here in xda)
