Hello, I purchased a Korean (I live here atm) Galaxy Note 4 about three weeks ago and have been experiencing extremely rapid battery drain.
Initially, upon unboxing I noticed that I'd get about 2 hours max screentime with 3G browsing usage before the phone would power down. As a result, I brought it to the Samsung store in Seoul last week and they gave me a new battery. However, the new battery appears to have changed little, though I was getting up to three hours screentime maximum afterwards, so that was a marginal improvement.
Yesterday I did a factory wipe and reset the phone, deleted all the unnecessary apps, and reinstalled just the basic extras one at a time to see if that would improve things.
Today I took it off charge and noticed the drain is still noticeable. When browsing websites OFF the charger cable I see the power drop by 1% every 3-4 minutes. Is this normal? I calculate I'd get between 4-5 hours of power at constant browsing at this rate, which would be fine if spread over the day, but the other issue is that even on standby the battery usage is noticeable.
Even following the factory reset I notice that besides from the obvious "Screen" power usage, "Android System" is one of the biggest drains on the battery. Currently it is using between 25-30% of power, and if you look at the sleep log on the battery (See attached) you'll notice it waking lots even with screen OFF. So it seems there are some extremely battery intensive processes that are going on all the while in the background. And when I click on the Android Services battery breakdown, I get about a five page list of processes that are running (also attached), which really does seem excessive for an operating system alone. Could it just be lots of network installed bloatware?
Unfortunately, Samsung told me that past Monday I'd have no chance to bring the phone back for a refund, so now it seems I'm left with fixing it myself or selling it.
As a Note 2 owner who relied on the great battery life I am very disappointed with this.
I'd really appreciate any suggestions for getting to the bottom of this -- or figuring out if there i simply a hardware fault at play here.
Here is the long list of Android System processes I've got running:
Root your phone and control your awake events by App Ops, Amplify, maybe Greenify.
Bloatware sucks. I deactivated almost everything and it works for the moment! But root will be the only way to get more Performance. S health for example i a battery drainer....

Thanks: how many processes are running in your Android system now you rooted?
Is this the solution? Because obviously if I root, then it makes getting an exchange even more complicated..
Can you tell me how to take a large screenshot? I will post u the process list. My device is not rooted. I will wait to be sure that my hardware is ok.
Thanks. I actually had to make that in Photoshop. It took five individual shots.
Quick update at end of the day.
13 h phone on with 3h45 screen and I'm left with 3% battery.
Is this really the best a thousand dollar phone can do?
Chad you have to many apps in your notification bar! Check this apps pls if they are running all the time. Is this a snpadragon device? Display @ auto brightness disable all nfc / smartstuff

That's what i disabled [emoji6]
Not sure what those apps are as they are not visibly running.... i feel the issue may be related to the sheer amount of bloatware the korean providers bundle into the system...
Is there any tool to do an optimum battery test so I can figure out if it's software?
Wakelock detector but u need root.
Dude go to appsettings and start disabling all that bull**** my phone is good now. Check every app an decide to use it or not.
My note4 SM-910L from LG+ korea too
And this is my battery stat
As you can see i use airplane mode all the time. Only use wifi and battery still good ( play shadow fight, ppsspp ,... ) and sot can reach 5h easily.
Sync takes up a lot of battery
Yes but deactivating all services of a device takes all the features u pay for.
I got up to 5-6h display time on my 3rd charge.

Well, I'm in the Samsung Service Center again and they just updated the build of the OS, slightly different one although it's still 4.4.4
He said that would fix it, but I spent fifteen mins in the shop after getting it back and battery drained 5% already.
Yet all his diagnostic tests are coming back fine...
They're taking another look at it now, but I'm not particularly hopeful of a solution.
And as someone is suggesting: what is the point of buying these new devices if you only have to disable 95% of functionality to get decent battery life?
I'm convinced there is a hardware issue at play in mine, my two year old Galaxy Note 2 gives about 30 % batter than the brand new note 4; that can't be right!
Same problem here
Hello there i got the same problem with my rooted sm-n910k and i installed amplify and now i can see where is the battery drain . I got battery drain from :
Service Name :
com.sec.android.app.soundalive
Wakelock :
RILJ1
I will also atach some pictures to find out if you got same problem like me
I have the sm-n910k too (Korean standard one).
Since going to the shop nothing is better.
Today 14 hours of power, with about 2.5 hours of screentime (not web browsing, but mainly s-note stuff).
Is this really it?!
Is Is it because the SM 910K (Korean version) uses a different chipset to rest of the world that the battery is so poor?
The guys in the Korean Samsung Service center shop told me that the battery life I am getting is NORMAL.
But look at the attached screenshots: <13 hours. Is that really normal? If so I am very, very disappointed...
So guys sorry if this post is "usual". But I bought the S5 for about 2-3 weeks now from second hand, also bought a brand new battery and I have remained on Alexander Devbase CPD7(MM 6.0.1) these days. My question is...how do people actually get 5-6h of sot on this phone? My best score was 3:46h of sot. Please give your app usages and tips. Oh and welcome me since I'm new to the s5 community Cheers.
Welcome lol
Nothing special, I just run a debloated stock ROM, 50% brightness is the only thing I change, WiFi is enabled 24/7
I was just showing my battery life with the new OTA 6.0.1 firmware earlier, over 4 hours with 50% battery left

All depends what you're doing on your phone though, if you're using that battery hog facebook app, or even have it installed, it's gonna drain your battery much quicker, or playing games etc
I use mine for WhatsApp, emails, texts and calls mainly, some browsing and easily get 6 hours SoT, today I was headed for 8 hours but forgot and plugged it in at 35%
First time posting. Bought two new S7 Edge phones in late November. My wife can go a day or two or three without charging, similar use with hers. I am lucky to get maybe 6 hours ever since I bought it. I don't use it for gaming, I use social media, email, news, some music, take a lot of pics of the kids, Photoshop, reading, research, etc. My phone is my laptop replacement.
I installed CPU-Z a while back because my phone is often hot. Sensor readings often exceed 150° F with battery temps exceeding 105° (with very little activity).
I've tried charging with rapid charge disabled, decreased screen brightness & resolution, shut down background processes, did malware and virus scans, factory reset, etc. No change.
I do have many apps installed on my phone and I have moved as many as possible to the 64Gb micro sd. No difference. Looking for suggestions. Is this a defective phone? Should I be looking at a replacement? My Note 4, Note II, and Thunderbolt all had much better battery performance.
Your help is appreciated.
I can get like 10-11 hours, did you check "Battery" section to see what is draining her ?
Well I can get even 12h of sot so I don't know how can you get such low battery life. Also, if it heated up to 100° Celsius the battery is not healthy anymore,you should change it
There is absolutely no way that U can get 12 hours of SOT on official rom and with average usage. Don't confuse the OP.
About the problem,
Did U try factory resetting the phone? That should be the first thing to do when the battery is draining abnormally. Also. send us pics of battery usage.
Sorry for the late reply. Apparently I turned my notifications off.
Yes, I have done a factory reset twice in the past few months. I think I'm going to backup in the next week or so and do another one and this time try installing only a minimal set of apps for a few weeks and see how it goes.
Here is a screenshot of my current battery usage. I charged the phone twice today. It's actually doing ok at the moment, usually android system uses the most juice.
Also a shot of the current temps.
Thank you all again!
I can't cope with this bad battery life that came with Oreo. I'm not a heavy user and I do have Bluetooth enabled because of my Gear S3 - but at this rate I need to recharge my phone twice a day...
I've already done a restore, removed all unnecessary apps, replaced mail Push to 15min and other changes for a better battery life. But nothing helps.
Do you also have the same issue?
I personally have exrltraordinary battery life 6 H SOT.
Better than nougat

Lucky you, can you tell me more about your usage and settings?
I also have a bad battery life comparing to nugat. On nugat it was around 36h and on Oreo around 20h

Quad hd, allways on during day....

auto brightness seems to be stable and a bit better but the battery is horrid i left home at 6:20 am with 100% i'm already on 53% with bluetooth audio and whatsapp really.

turn of "mobile data always on" inside Developer Options and see.
Can someone on the internet identify this underlining issue of battery getting exhausted so rapidly. On Nougat it was just fine but after updating to Oreo, battery backup is gotten worse. Whenever I see battery stats Android OS and Android System using absurd amount of battery just below the screen usage time and sometimes either of them is on top in usage.
I have done numerous resets with and without data restore. But nothing changes.
I think have found the problem. Samsung Email, after Oreo this app keep on in background every time (do not look in battery monitor but in applications) . I already try one day without any mail app and the gain is enormous and other one day with other mail app (Gmail) and the gain is also enormous. For last day (tomorow) I try again with Samsung email for confirm the result .
Same problem here but with my S8+. Went from 7h SOT to 4h SOT. I also deleted samsung mail app and replaced it with gmail but even that didn't really fix it.. Other than that Oreo is really good in terms of performance, but I want my old battery life back. Hopefully Samsung will fix this with the next update.
I am really surprised some people have better battery life with Oreo. Maybe it has to do with Snapdragon vs Exynos ? I have an S8+ with Exynos CPU
I had great battery life with Oreo beta 6 but then I "upgraded" to the final version CRAP and my battery life is now a crap!
Currently on my S8Plus(Exynos) I am unable to get a full day of battery backup with moderate usage. SOT usually lies between 2-2.5hrs max in 12hours on battery.
Also I don't have Samsung Mail App. All things stock with limited no. of 3rd party apps likes social media apps, 2-3 shopping apps and also 3 gmail accounts synced.

What's your SOT and how many apps are installed also do you use location services. If possible share your battery stats here.

Hi I went by your suggestion and checked in apps to see which one were consuming the highest battery & my culprits are Bixby Global Action & Bixby Service each consuming 11% each (Please see attached files). I am also attaching usage statistics of today. Both before disabling services and after disabling. (See the time to figure out). Will get a better idea tomorrow.
Suggest everyone to look in to their apps usage and post their findings.
EDIT: I just checked I had used the STOPPED the applications but forgot to disable them. Have disabled them now at 17.45 PM and will update later.

Be careful the percentage of consumption of this app is a is a consumption of many app from "android system "
But it's not worth to disable lot of Bixby
Derp
Battery on Oreo is way better than Nougat. Never had over 4 hours SOT... And I have tons of apps installed. 143 apps to be exact

I get regular btw 7hr and 8hr SOT on Nougat.
4-6 SOT is not so good as i expected...
Hi guys. I am a S10+ exynos version user from Indonesia. Recently I just bought the s10+ and after a few days i realize that the battery is draining quite fast. I need your opinion on this, and what should I do? The battery reduced about 40% after only 1 hour 40 minute sot and 12 hour 46 minutes device idle. Don't use it that heavily since the last full charge. Sorry i cannot figure out how to upload the picture. Please help me. Regards
