Huge standby battery drain - Samsung Galaxy S9 Questions & Answers

Hi everyone,
I am really helpless and do not know what to do anymore. My S9+ is draining battery overnight, in 6 and a half hours it drains 10%, even if always on displey is set to be turned of between 23h - 06h.
I am on the latest BTU firmware, I have tryied every tip and solution which I found on xda in order to get it better but it is still the same. I turned of almost all features like sync, location and also set all apps to be power saving.
If I use the phone a lot, I will get 4-5 maybe even 6 hours of SOT, but if I do not use it a lot, I will have 2-3 hours of SOT in total of 16 hours usage.
Any help or tips? I do not have any battery draining apps installed.
When I go to check in the battery stats I do not see anything suspicius, it says AOD 2 %, Device Idle 2%, Android OS 1%, Android System 1%, Screen 1%, Device is passive 1%.
Now I am trying it with a all black theme but still no improvement

Screen on time

It's amazing how much we actually use our phones in a given day, especially when we watch "videos"! Rate this thread to express how many hours of screen-on time you can get on the ZTE Axon 7 before depleting the battery.
Then, drop a comment if you have anything to add!
One of the better SOT phones I've owned since coming from smaller 4.5 inch screens. I easily get 4 hours on a long day (16 -18 hours off the charger). I watched 2.5 hour movie the other day and did some more stuff. In 8 hours, I had over 5 hours of SOT with 47% battery left.

How are you measuring SOT? I can't find it in the stock battery stats.

GSam battery monitor.
There is a free version and a paid version, not sure which one this is but it'll get you close: https://play.google.com/store/apps/details?id=com.gsamlabs.bbm

Does better battery stats require root? Does it read system stats or does it create its own?

I don't like gsam because it doesn't read the SOT from the system. It records it's own stats.
GSam battery monitor allows you to see the stock android battery stats and screen on time from there by going to the menu on the bottom right, clicking more and then Battery Use - Built In. If there is an easier way to get to stock android battery stats, I'd love to know.

"BetterBatteryStats is calling the "batteryinfo" service of Android to retrieve data already lying there without generating overhead" and no it doesn't need root

What settings do you guys have setup? My battery is down to 27% after only 8.5 hours off the charger and not much video watching. How do you have your phone setup concerning gestures and everything? I use the fingerprint unlock and the double tap feature and so far I am not impressed with the battery.
What settings are you using? I'm barely getting10hrs of battery

Nothing special, really? It's basically stock, I just disabled some stock apps: Browser, calendar, stock email, Gmail, Hangouts, and stock messaging. Everything else is left alone.... I even installed the actual Facebook app (aka: battery eater) for the first time in a few years, since my battery can keep up now.

No screen on time. I am in an area where I get no service and was using WiFi, so today I turned on Airplane mode and then WiFi and it seems to work a lot better. though I still need to investigate is battery drain is bad when using the phone in normal service area.

This is the best phone I've owned in terms of battery life. With nova launcher and using nova's battery widget I can see my SOT. I average 5:30 which is alot for me. I have gotten as much as 6:40! This is all usually over 12-28 hrs. The phone is just phenomenal, just wish the camera was better.

I would believe it. I got about 5 hours in my last run. What I think ate up about 20% was listening to music through the speakers.. The phone drained faster than normal Witt the speakers on at max volume.. Which makes sense and is 5000% tolerable because how amazing they sound.
Furthermore, if I could get some stronger cell phone signal, that would help with screen on time too. I never have no signal, but I never see over two bars of signal either.
Sorry about double post.. Forgot to include second one..
Ok, I thought this was a battery beast but I think I was wrong. I don't expect any phone's battery indicator to be totally accurate but I've noticed that if I top the A7 up a little the battery doesn't drain *at all* for a long time. I've been letting it go down to 30% then topping it up to 40% where it stays without moving even while I'm streaming music and surfing for half an hour. Fishy.
I thought that as I was on about 3:30 sot at 40% I'd let it go down further to see if it would reach 5 hours. Three charging cycles in a row the phone has hit 19% and then reported that it's empty and shut down.
EU model build B03.

A5 2017 amazing battery life normal?

I'm at 15% and got 8h23 SOT. Surely will hit 9h mark I assume.
4G enabled but mostly wifi, volte, Bluetooth. Watched 2 series, was on the Internet all day and some Internet radio on high quality. So no compromises.
Haven't had this much battery life with any smartphone, flagship Sony, galaxy s7 edge and oneplus 3t recently.
Anyone else have this? Didn't expect this at all..
Edit: almost 10h SOT short a few minutes. Added screenshots to show.
Yes, this is normal for this device. I'm sorry for your inconvenience. Since you're dutch, you can read this for more information on batterylife.
Well yea, will need to send it back!
"battery life too good"
Yes, it is amazing and it is normal. It seems Samsung finally put some effort into the optimization.
Samsung has nailed it this time

Mine gets as high as 4.5-5 hours of sot. 2G, full reception, data off, BT off, sync off, occasional Wifi usage, Facebook crap disabled and AOD on. quite disappointing.
Is this normal sot...after 3 days of use?

I think so, 52hrs of standby time also takes some batterylife. So.... Did u also use always on display?
No...I dont use always on display. And my sot i about 7h after 2/3 days.

I hit the mark of 1 day and 19 hours with the first half charge, right after unboxing... Although it seems it won't repeat as my previsions are for 22 hours with 80%... Anynway, very good battery life
Look at this stats . Wifi +sync +4g allways on.
Best device i ever had regarding battery life
Battery life is simply amazing on this device... with Nougat
All sync on, wifi, BT and so on.. google services such as location history and assistant...
After 2d 4h 45m on battery and 7h 21m screen on I still have 23% battery left !
Samsung made a mistake in the design specifications of the 2017 series. They currently use a battery that uses a low-radioactive component that is superior to the standard battery but it has not been tested for the long term. just kidding It's not only the A5 also the A3 shows this kind of battery stats. Battery usage with GPS (not including wifi/cell location) is also very good from my experience with A3. But have noticed that after a week or so the battery will go down faster but am not so sure because of irregular use of chat apps running that receive messages frequently.
I'm on Marshmallow. I like to know how Nougat does in comparison
Is there still anyone who get these kind of stats in nougat? I got 6h of sot and I'm at 12%. Is this normal? Also, I woke at 17% (didn't discharge a single % overnight) but it dropped to 12% only by using fb, samsung default browser and settings...

I get similar, seems MM had bettery battery life.
Yes, A7 is champion in terms of battery life.
That's weird my A5 just got the Oreo update and now the battery drains faster than before... When I check the device maintenance I can see cell standby consumption is higher than the screen. I wiped all the data and cache, reset factory, restet network settings, disabled sync, location... and the issue remains. I don't know what to do to solve the issue and am afraid they're not going to take the problem seriously if I send it back to samsung... Anyone can relate?
It is not in a single charge but that's what I get. The stamina is still correct though so idk if it is more like a display problem or if it does show the real consumption and so the battery should last way longer.

need your opinion

I brought an used a5 2017 for $183 (12500 INR)
8 months warranty left ...device is overall awesome...but im concerned about battery ...battery is good almost give me 6-7 hr of screen on time but it drain in ideal condition. It drains almost 6-7% during night time... Is it normal for this device..???
This device is running on nougat

Always on display will not take really any power. The a520w has an AMOLED screen, so only the pixels lit up is being used not the whole screen. I get about 2 days on one charge and I use it about 2 - 5 hours playing games and 1-3 oh YouTube. Try using an app to stop things in background.

S20 serious battery drain issue

My s20 Exynos is draining 1 percentage battery every 3 minutes when screen is on. Location , bluetooth, aod and all are off including Bixby. I'm using single sim and signal is very good. Using wifi for data. Can't understand what is causing battery drain.
Is my battery fault? I purchased just 2 weeks ago and it's really frustrating me.
Thanks a lot for your list. I'm going to do factory reset and check how it improves. Its a big pain moving all files to pc and copying back. I'll update my status in some days sure. My sot is very bad now, getting 3 hours only

For the moment it's normal let the phone learn your habits and your usage do the update and do 2 or 3 full cycle charge (20 to 100%) after that it will be good if not you can ask a replacement because you have a damaged product

It has completed learning habits already. When I put full charge it shows 1 day 2 hours left but it is consuming 15% when screen is on and doing web browsing with wifi.

Check for an OTA Update, some Exynos users are reporting lower battery drain after the latest update.
Its up to date. Yesterday I received wireless dex one ui 2.5 update. Battery drain is still worst. I have cleared cache also. Anybody help me to solve this please?

I had similar issue on my S 20 Ultra but even worse. After update to One UI 2.5 I had huge battery drain,overheating, can not even reach 120hz and had lags every 10 secconds no matter what I was doing.
I tried to: Wipe cache did not help, new function apps optimizer did not help, restart did not help.
I found that new "design" Edge panel ate approx 8% of battery over the night so I disabled it ,restarted my phone and everything went back to normal.
I never had such a problems with any phone in the past. This is embarrassing!
Hope this will work for you too!
May I know how did you know edge panel took 8%?
Because battery care does not show system apps power consumption. Accubattery and gsm battery also did not show system apps power consumption.
I struck on finding which one is causing this huge power consumption.

settings -> device care -> battery -> battery usage-> edge screen
edge panel is a part of edge screen "app" which I can normaly see in the list.
I've checked it. It shows only 1% was used for edge screen. Samsung has hidden the feature of showing system usage like screen , wifi, cell radio signals etc.
Why the hell they did this. If it is available we can easily find which one is causing issue
Any ideas?
Try running med power saving as a test, see what your drain is then.
What is showing as your biggest battery drainer? You can try grabbing galaxy labs and seeing what's going on via battery tracker. You can find galaxy labs in the galaxy store, if it's not there then someone posted the apks in the apps forum as it's only available in some regions. . It gives you a little more granular visibility in batt usage.
check out gsam battery monitor from google play store. You will need to enable permissions to allow it to collect enhanced stats. This is done via ADB ( Android Debug Bridge), which is quite a simple process. The app walks you through enabling it step by step. This may help to identify what is going on. I can't remember how much detail it gives on system processes. But it is free, so worth a try
Newest update has also tanked my battery. Have a S20 snapdragon.
welcome to the world of exynos
see my post #311 here https://forum.xda-developers.com/galaxy-s20/review/screen-time-t4010447/page32 it may assist with some options to tweak to help with your drain. I got the new update a few days ago and my battery use is still fine, around 3% drain overnight for 8 hours.
Battery and Lag
I have the S20+ and when the new software BTH5 was installed...it was a nightmare ...huge drain and lag was terrible...I wiped cache no difference then factory reset which I hate doing due to the reinstall........however it is absolutely perfect having done that. hope that helps
Install Better battery stats from plays store, give it all the required permissions, do a full cycle and check what is draining your battery there. It's a very good app, perfect for troubleshooting battery problems.

There is no app causing battery drain because I have put all apps in deep sleep mode. Accubattery and Samsung labs battery tracker showing apps power consumption only and not hardware power consumption.
I've charged for 92% and it went to 82% in half an hour of sot and 2 hours of screen off.
This is very annoying me to find out where is the problem
No issue here. Do a factory reset may help

Question Z Fold 3 battery life discussion

Hi to all F3 owners hope your enjoying your new toy?
Only query / disappointment for me so far is that battery life is nowhere near as good on Fold 3 as it was with Fold 2.
1.5 hours light usage today and I am down to 58% - mostly indoors and on WiFi
I expected the latest Snapdragon 888 to have as good of not better power management than last year's CPU.
What is other F3 owner's experience?
WhatsApp has been running for 25 mins and eaten ~30%? You have something deeper going on there it looks like.
Digital wellbeing is a battery eating feature itself. Turn it off and you will get more battery time.
I have similiar problems with battery. But in my case, it's Calls that take a lot battery, windows link too..

Believe it or not to today has been very light usage compared with a typical day
I have same Apps and settings as i had with my Fold2 so don't know what's up
Hopefully after a few more days of battery usage learning things will settle down

A completely different list of apps with top battery usage is shown with the 2 screen shots...hmmm
This happens with every release of every new phone. It always takes a few days for it to settle as it's downloading apps, settings, updates, etc. It's WAY too early to compare battery life. Give it a week.
Give it time to take a calibration and you to stop using your device not in the muscle memory you and the phone will develop.
Then they'll push a firmware upgrade that destroys all that hard work you and your new fold put in getting to know one another.
See Buds+ battery stat.
Only paired them with phone 2 hours ago to so recording 10 hours of background battery usage is quite an achievement
I reckon the battery usage stats are unreliable on my Fold3 ...
Estimated 15 hours on a full charge..... Spectacularly BAD if accurate long term
Battery drain (mostly standby) in first hour is 6%

Total app usage in 90 mins since coming off charge is 1.9%
Therefore standby drain is 4.1% per 90 mins. Not ideal.
I didn't notice a particular issue whith battery life on mine l nearly 10H of uptime with 35% remaining is alright in my book)

Update: today I put !y SIM card in another phone and used Fold3 on WiFi only
Normal battery drain and good SOT
Can only hope September OTA improves network radio power consumption

Accubattery estimates 6hrs SOT time is, which I think is a out what I got from Fold2. My previous high battery drain does appear to have been network / radio related
