If you are using Exynos 4g model than tough luck. My max sot is 4h

Im testing still (today is the first full day with It)...
...but It seem than It consums several battery in sleep mode.
This night at 3 am It had 100%. At 7:00 am I waked and It had 92%.

I am seeing unusual battery drain with my snapdragon version. 16% in 9 hours is way too much. My S20 plus never used to do that. I also give samsung phones time to settle down with battery usage and it's been 1 week since I got it, so it should have been pretty settled by now.

Yeah, I got my FE 5G a couple of weeks ago and the IDLE battery drain is a bit much... Also, anyone else experiencing a lot of battery drain when in 120hz mode? The reviewers said that it was minimal, but I found at least a 2 hour increase in battery life when I set it back to 60hz...

Hello, I've like 3-4% max overnight in a area with 1-2 out 5 GSM signal strength
Try to put it in Airplane mode and see the consumption in the morning - you should have max 1%

So far I have: 4h40 SOT on 120 hz and 6h20 SOT on 60 Hz - down to 15%, dark mode, WIFI only, Location On, Battery in Optimized mode
As battery drain per hour GSAM Battery shows me 2-3%
I had 5-6% on S20 Plus Exynos

I have mine for several months. First time Samsung user and not a heavy user. I go by the 80% rule, charge to 80% whenever I can using GSM Battery Monitor / AccuBattery. Overnight, battery will drop from 74% to 60% or less. I thought there is something wrong with my phone. I checked battery usage from time to time, system and Android uses upwards to 25%~30% over 8 hour period. This is regardless if I have cell on or in Airplane mode or WiFi off / on.
After reading your comments, I realized it's something that Samsung has done to make it consume more battery than necessary. I am not sure what I would do next. But I am done with Samsung.

BATTERY LIFE: Standby Drain

When you sleep, does your phone sleep, or does it stay up all night and crunch 1s and 0s? Rate this thread to express how you deem the speed at which the Note5's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.

I'll test this later today. Charge my phone to 100%, and right before I close my eyes, I'll unplug and see how it does. I'm curious as well.
Typically 0.5% per hour or less with lots of bloatware disabled (200+ apps). Couple gmail accounts, s note and scrapbook syncing.

So I unplugged my phone when it reached 100% and got a notification saying the battery is fully charged and unplugged it at 10:40 pm. About 7 hrs and 20 mins later, my phone dropped to 93%. That's about 1% every hour. My phone is stock, no root (yet) with 17 apps disabled. WiFi is on, brightness was on the lowest setting and all accounts on my phone sync through the the night.
I've never done this with one of my previous phones, so I can't really give you my opinion on how I feel about this. Let me know what you guys think. I'll try disabling some more apps and doing the test again and see if that has some effect.

if you are rooted and have xposed. download Mobileactiveradiofix...bassically some apps you are using that utilize mobile data, after you turn off the screen it still using data....thats the gist of it.
Drain about 1% per hour.
Tried 3G all the way. Not much savings compared to LTE all day
I have the 920CD Dual sim. Horrible Battery standby. I lose 2 - 3% per hour on android system usage while i'm sleeping.
I tried disabling apps etc but to no avail!
During night my phone consumes up to 30% of battery, my stand-by is 16hrs at max!!!. I love my phone but there is an obvious problem about it.
On the other side my wife has the same phone and her battery withstands up to two(2!) days.
(Hers is running on stock firmware with simple tuning, mine is also on stock but i checked and disabled almost everything)
My phone is ; N920CXXU1AOH2 hers is N920CXXU1AOGF. Is there a way i clone her phone firmware and copy into mine?
I think you guys above may have Wakelock. Mine started up recently and it drains up to 15% of my battery from just a bit under 2 hours. Before that it would be fine. Unplugged all night (8hours) and lost 2-3% battery
I couldn't believe this rating was so low. This is the best at standby. Absolutely phenomenal. It's literally around 1-2% an hour. I can get home after 11hrs and still have 70% left. Usually it's around 50% with 2 hrs of screen on time / use.
Got an update yesterday. ..it includes the doze feature from marshmallow. ..vastly improved the standby time
ścribbled from my Note 5
I wouldn't call 1-2% per hour idle time phenomenal, It's average at best.
0.5% per hour (or 2 hours per 1%) I'd say that's very good.
3 hours per 1%, that's excellent. This happens to be my Xperia Z3 Compact's idle time when I sleep.
Phenomenal? It would need to be 4 hours per 1% idle time.
My Note 5 is doing 1% per hour currently.
My iPhone 6s Plus can go over 7 hours standby and still be at 100%. One of my biggest peeves with Android was battery drain. Just switched with the release of the 6s and am very happy. Had the Note 5 and still have the Nexus 6. The doze feature still can't even come close. And it only works if the phone is shelved. Not in the pocket. Not good enough for me.
Please everyone who has the drain, write samsung feedback on their support website. It is most of the time caused by the wlan_rx_wake, wlan_cntrl_wake and wlan_wake wakelocks. I am trying to find a fix but so far nothing has helped me except turning off wifi.

Really? I can live without WiFi most of the time if it helps my battery.
I was getting great battery life, I stopped using the Note 5 for about 3 weeks while I reviewed some other devices and when I return I'm loosing 5% an hour, doing nothing. I've done a factory reset once, slightly better, but still not great. Might try another tomorrow.
Let us know if you find a fix.

just like you .. I come from a s6 and did not have this problem, hopefully be resolved soon
During night, I switch off mobile network and wifi, but both SIM still active for phonecalls. Drain this way is around 0.5% per hour or 3%-4% per night - depending on how long I sleep
Frankly, I only used the phone with the latest update so, I have no idea about battery performance before it. Anyways, I'm getting great overnight battery performance, with 3% dropping in 7-8 hours (mobile data, wifi and bluetooth off).
all data and BT off and you're dropping 3%? Turn your phone off and you'll drop 0%
Mediaserver, system and kernel kill my standby. Is it worth factory reset or should I hang out for marshmallow?

Same here
Flightmode? Wifi on? GPS on? Charge-Level of the Battery?
Mine loses 5-7% in 8h in Flightmode, without Wifi and GPS on when in the 70% Level. Maybe it would lose only 1% when fully charged because the battery gauge stays at 100% for the first few % of drain (~ 100mv on mine).

Can everyone here note whether or not they've rooted their phones or not. I'm trying to determine whether the AI is assisting people with their amazing standby times/battery life because when you root, supposedly the AI doesn't work properly any longer

I'm rootless. Phone is sleeping better than me.
pretty impressive
Mate 10 PRO
I have lost ~0.4%/h with dual sim cards from the same carrier.
Official rom, no root
WIFI ON, MOBILE DATA ON, LOCATION ON (high accuracy), LOCATION HISTORY ON. all apps in the background were closed/cleared.
It was 95% after 11 hours, the screenshot shows 94% because I have forgot to take the screenshot and I have used a bit the phone.

Yes that's really impressive and similar to what I'm getting. What other users have reported (and also in my experience) is that the battery meter takes a much longer time to drop from 100% to 95% compared to maybe 80% to 75%. You can try repeating your experiment above but start when the phone is 80% or 70% and see if you still get the same rate of discharge. I'm curious to know your experience. Cheers!

I will try that also but next experiment is to activate the data saver from: settings --> Wireless & Networks --> Mobile data --> Data Saver change from OFF to ON.. I want to see if this helps a bit...
edit: to see if it helps even if the WIFI is always ON
Guys, give the phone some time to improve performance and reduce battery drain.
The NPU runs when the phone is in standby so, on the first days it's normal if the battery drains faster. If you are changing phone settings all the time, the NPU unit will try to optimize it again.
Also, the latest firmware from HUAWEI improved a lot the battery.
Mine lost 1% last night. All on as usual. I guess if you remember to closely all apps that help...

I'm getting roughly 2.5% battery drain per hour during standby. Worse than the OnePlus 6t
From 100% I unplugged at night around 23.00 and in the morning 5.00am I've got 92%, it's on Wifi.. Worse battery for s10+ Exynos
As far as I remember, a few years back, my old Galaxy phone with customised rom will only lose 2% battery during the night. Now, it's about 8%-10%.
Do you have AoD enabled? And also do you have Mobile data always active enabled in developers options? (it makes your phone keep mobile data connection going even while you are on wifi and thus draining battery faster)
My S10 is draining 2,5% per hour during the night after 3 times charging and discharging (slow charging) My old S8 about 1%. I think 2,5% is to much..
Samsung needs to fix this thing. This problem used to come in old smartphone days. Its 2019. How their QA team passing it?

any idea how to reach samsung regarding this battery drain??
Twitter maybe? Or Discord?
First day back at work and between 7 am and 16:45 I lost approx 20%. In that time I used BBC news for about 10 mins and Facebook for 10 minutes. No AOD and I had medium power saving mode on. All that time on 4G with strong signal.
Based on that I am losing approx 2% an hour which isn't much better than my 2 year old S7 if I am honest!!
Very bad standby drain.. Even when S10+ full charge 100%, set to airplane mode, wifi off, data off, sync off, AOD off, and set many app to sleep, from 23.00 to 5am, battery left 92%... It's worse than any huawei
1% over 5 hours at night.
AOD on tap.
WiFi LTE Bt all off.

Indian exynos version

I have around 1% per hour on S10 exynos model, which is normal.
Im on SD + and the battery life is the WORST I've had in years on any phone. Combine that with the HORRIBLE fingerprint scanner, this junk is going back. Im not a Guinea pig for Samsung. Rush to get crap out is not an effective way of doing business, with so many competitors out there.
3% over 7.5 hours last night
No deep sleep?
S10 exynos here
No battery drain on my Exynos S10. From 23:00 to 6:30, only 3%. Same as S9+
AOD, BT off
Wifi on
But on 4G it seems worse but didn't test it yet.
I left my S10 with airplane mode turned on last night, and after 6 hours it went down from 100 to 93%.
Thats not good at all as I had turned off everything.

Anyone noticed battery drains bad after the FPS update.

Wondering if anyone facing this issue because when I first got the phone the stand by drain was really bad but with the March 1st security update the battery was really good. Since the FPS update the battery seem to be back to before let alone the FPS really bad too, at least in my case it worse than before the update. I tried to reregister the FPS but I have to presses really hard for it to accept the scan or else it just keep telling me to press harder. Snapdragon version by the way.
For Exynos version after FPS update battery drain is also worse then previously. I contacted Samsung for this issue but no response until now

No phone comes close to my XS Max 12.3 DB in standby. Bluetooth connected to my watch, WiFI, et al. Never tried airplane mode. Its battery life when being used is not as good as the S10+ but standby certainly is better so there's that.
TBH I stopped worrying about standby drain when wireless charging came about. Now if it's draining more than a few % per hour then something is clearly wrong.

Phone lost 24% overnight. Culprit seems to be Facebook services, which in turn triggered Google services (for GPS location). I've disabled all the FB crap now and I'll see how it goes today...
Update 19/02 - I'm using Swipe Pro for Facebook and since then the battery seems to have settled. Getting really good battery life now with not too much standby drain.
The 730G is dreadful on my Xiaomi Mi Note 10 - which has an even bigger, ~5200mAh battery. It performs much worse than my OnePlus 7 Pro with 4000mAh. IMO the chipset (730/730G) is NOT power efficient.

Likely a device specific problem. Notebookcheck test power consumption in idle, sd 730/g phones are within the same range of comparable mid range SOCs. A71 in particular consumes pretty much the same as Pixel 3a for example (Snapdragon 670), more under load but it's quite a bit more powerful as well, consumes less than Galaxy A51 (Exynos 9611), way less than Huawei P30 lite (Kirin 710) and quite a bit less than Oneplus 7 pro as well for that matter. It uses the same modem as sd 710 and 712 so that's not a problem either.
I have 2-4% standby battery drain. But I checked all apps for background battery usage, I don't use facebook app. The only background apps I use are email, sense flip clock and I use greenify on top of that.

I have about 15% battery drain in flight mode during the night. I feel this is a CATASTROPHY! What is causing this??? Is there a FREE app that can find what app is doing this? If I check in the settings, it says all apps has drained 0% during the night..
Hey, am thinking of buying an A71 and was wondering if you still have battery issues please?
I have wifi off and Bluetooth for watch, No FB . I get 1 or 2% loss mainly messenger lite , and my games I don't shut down .. with wifi on an average day its about 40% loss . that with wifi always on , games being played, youtube etc ... Since taking of FB I have noticed a huge difference, as before I was loosing 10/20 % at night and 70% in the day ... now I charge once every 2 days, which is not bad ...

if U use Facebook Messenger , just remove it and test your phone again
if its not gonna helpful , just check what app drain your battery in setting
Same problem. Just got mine and lost 25% overnight. AOD is not even on. I disabled Facebook the instant I took it out of the box so it isn't that. Must be another app but not sure which. All the same apps I was using on my previous device and had no issues like this.
My battery life is horrible on my A71, I come home from work with 10%, on my P20 Pro which has a smaller battery is 65-70%. I have already used package disabler to disable the crap and its still happening. Going to be returning this phone.
Standby Drain on A71 Samsung
I have the phone for 1 week now and the battery I can say is performing very poor. Just got it to 100% then after 1 minute suddenly went to 99% and after 5 mins suddenly went to 98% just on standby mode. Can anyone please explain me why this is happening?
My device is always optimized (no background processes running). Every app (even the useful ones) I have put to sleep, which means I'm sacrificing on not getting the notifications when the internet is connected as those those apps are put to sleep but I did it just to put my battery on right track. Still no significant benefit.
Standby drain is the biggest issue I'm facing. Early 2% drops from 100% for no reason at all. At night time, I see at least 3% drop in 4 to 5 hours standby with wifi off and zero brightness and dark mode on and always-on display disabled, battery saving mode on and no app running in the background.
I'm having 1% battery drop every 10 mins for just reading comments on XDA developer or GSMArena with brightness to 0%, no extra app working in background, have put all the apps to sleep when not in use, no multimedia use, always-on display disabled, dark mode on, battery saving mode on. So, when I'm using Chrome, I'm only using Chrome. When I'm watching Youtube videos on app with 20% brightness and 60% volume, I'm having 1% drop every 7 to 8 mins. I see variability between each % drop. Like for example, sometimes it drops 1% at 4 mins interval and after that it will take 8 mins to drop a percent.
I have never been so confused in terms of battery life before. Someone from Samsung should at least come forward and explain to us what is going on.
From the reviews, the new updates doesn't have much to offer in terms of battery life. I haven't gotten the update yet.

Every app (even the useful ones) I have put to sleep, which means I'm sacrificing on not getting the notifications when the internet is connected as those those apps are put to sleep but I did it just to put my battery on right track. Still no significant benefit.
Standby drain is the biggest issue I'm facing. Early 2% drops from 100% for no reason at all. At night time, I see at least 3% drop in 4 to 5 hours standby with wifi off and zero brightness and dark mode on and always-on display disabled, battery saving mode on and no app running in the background.
I'm having 1% battery drop every 10 mins for just reading comments on XDA developer or GSMArena with brightness to 0%, no extra app working in background, have put all the apps to sleep when not in use, no multimedia use, always-on display disabled, dark mode on, battery saving mode on. So, when I'm using Chrome, I'm only using Chrome. When I'm watching Youtube videos on app with 20% brightness and 60% volume, I'm having 1% drop every 7 to 8 mins. I see variability between each % drop. Like for example, sometimes it drops 1% at 4 mins interval and after that it will take 8 mins to drop a percent.
I have never been so confused in terms of battery life before. Someone from Samsung should at least come forward and explain to us what is going on.
From the reviews, the new updates doesn't have much to offer in terms of battery life. I haven't gotten the update yet.

Had the same issue and no matter what I did couldn’t fix it. I turned this off turned that off, lowered this, reduced that. In the end I gave up and returned it. Shouldn’t be that much of an effort but then it always seems to be with Samsung. Huawei for example it’s just ready to go and works flawlessly out of the box. For a phone that had 4500mah battery it performs nothing like it. I bought the new iPhone SE, it’s battery is tiny 1800mah or something and it lasts longer than the A71.
47% overnight, with no use. It's my second A71. The first, the battery seemed normal. But I did not observe this detail carefully. I changed it the first time due to the infamous discoloration defect of the screen on a gray background with low brightness. Now the second, in addition to the same discoloration defect of the screen, the battery does not last! I went to sleep, the battery at 47%. Wifi off. Mobile data off. GPS off. Bluetooth turned off. Vibration off. Always on Display off. NFC Off. Sim card removed. Only Whatsapp running in the background. All other apps have been configured to be suspended in the background. Approximately 8 hours later, without any use, the battery has zeroed. I have a Samsung Galaxy A7 2017, which has 3 years of use and a 3600MAh battery worn by hundreds of charge cycles, and yet its battery is WELL better than the Galaxy A71, which has 4500MAh and a few days of use. If a new cell phone discharges at this rate, imagine after about 2 years of use. You will need to recharge every hour. Turning the adaptive battery on or off for me made no difference. During normal use, it discharges quickly, but the problem is much more evident at night, when the device is not in use. It seems to drain as much energy in idle mode as in normal use.
The quality of Samsung's products is dropping every day. 3 years ago, you could buy an intermediary made of metal and glass. Protection IP68, OIS and Gorilla Glass 4. Today, the devices that cost almost the same as the high end, are all made of plastic. Without IP68. Gorilla Glass 3 (obsolete technology from 2013), without OIS, and batteries that although bigger, last less. Quality decreases and price increases. It is unfortunate.

The 730G is dreadful on my Xiaomi Mi Note 10 - which has an even bigger, ~5200mAh battery. It performs much worse than my OnePlus 7 Pro with 4000mAh. IMO the chipset (730/730G) is NOT power efficient.

I have the 730G 8GB ram variant on my A71 (This is the standard in the PH) and my phone lasts for 2 days with social media and youtube usage. OST is between 6-7 hours so no issues with the chip itself, the phone software is probably not optimized properly with the Mi Note 10.

So what's happening to the other people in this thread? Is it a case of just too many bad apples (bad/broken devices) or... ?

I think we need to put things into context first. None of them talked about what apps they had running, what settings they used, etc. Also, the other dude talked about the Huawei when that phone is known to aggressively kill apps very quickly in the background to save battery as a default. You can also do that with Sammy's but you need to activate it first.
As for my phone, it's set on its default out of the box-setting which is optimized if that at all matters.

I think we also need to look at which carriers are having issues. I have an open line international variant and I've had none of the issues in this thread.

Hey, am thinking of buying an A71 and was wondering if you still have battery issues please?

If you can find an open line (not tied to any carrier) international variant, it doesn't have any issues.

Phone lost 24% overnight. Culprit seems to be Facebook services, which in turn triggered Google services (for GPS location). I've disabled all the FB crap now and I'll see how it goes today...
Update 19/02 - I'm using Swipe Pro for Facebook and since then the battery seems to have settled. Getting really good battery life now with not too much standby drain.

Mine was a bit power hungry at first 6 months ago
Now that i shut off and tried to kill all processes but active ones my battery is AMAZING!
So to compare I read your post last night at around 11 ish to midnight topped off the phone to 94%, and it dropped to 93% just before i went to sleep
killed all the processes with built in battery device care and also greenify.
woke up today at 8:30am and the batter was at 90% and dropped to 89% after a min of use.
So 3-4% over eight or nine hours.... I"m pretty happy with that.
