My s6 wifi version has very good battery life compared to the s3 I upgraded from. Imo
I'm getting horrible standby time dropped 60% in 14 hours with almost no use. Where are those setting mine look different.
Found the settings, but mine are all set right. Doing a full charge now and gonna see if I can find anything using battery, but I suspect the tablet is never going into deep sleep
I found that there's a bug when charging with the keyboard case closed around the tablet.
If the case was closed and I put the tablet on the charger then take it off the charger. I would find it had lost 40% the next morning.
If I open the case & close the case after removing the charger I would only loose 1~2%.
What I'm thinking is that "Fast Charging ...%" that is visible during charging (even with the case closed) sets the screen to active.
However, it seems that removing the charger with the case closed, the tablet isn't picking up that the case is closed and keeps the screen somehow active.
(That's why, opening & closing the case resets that state and the tablet goes into proper idle/sleep mode again with the screen state in off mode.)
Tested it around 3 times now and each time it seems to be this exact issue.
Mine dropped 2% of battery per hour during standby with no apps run in the background.

+1 on this. I had an S3 and unplugged overnight I'd drop almost 50%. As a test I barely used the tablet for 4 days but didn't charge it and 4 days later I still had a good 30% charge left.

That's horrible battery life. I have barely touched my s4 since I got this and its dropped 20 percent. This tablet dropped 20 percent sitting for 8 hours today. Looking at battery usage it only shows 1% device idle and nothing else. I'm going to return and swap for different tablet. Hopefully I just got a bad battery, but it seems prevelent.
Ok, so that answers that. I returned my tab s6 and exchanged for new one and got keyboard case. The new one has been sitting all day and is still at 100 % with slight use. The old one you could watch the battery drop and on standby it would lose 20 % overnight. I have all the same apps installed and all the same apps disabled. Something was wrong with that tab.
Interesting followup is since I got my new tab it started showing standby drain again. So I've been experimenting and at first I thought it was leaving tablet in dex mode, but now I think it's related to multi-lock and using the "don't pause" apps option. I use this for videos and games to stay running while I check email of forums in multiwindow. I think when I have this one and I have apps running and close the lid or press the power these apps prevent sleeping. I'm still experimenting and hopefully will know more soon.

Thank you, I will definately give this a try tonight. Lost 40% tonight in standby. The battery drain is driving me crazy
Skickat från min SM-T865 via Tapatalk
yeah it's kind of random, to me it definitely seem related to leaving apps open when you turn off the tablet. I've seen the drain with and without the keyboard attached, in and out of dex mode. Some morning I lose 3% overnight, some mornings it's more like 20%

Going to try this as well. Mine has been dropping up to 60 percent overnight which is absolutely ridiculous. Even with airplane mode on and bloatware disabled.
I am having the same issues with my Tab S6 Lte.
Huge drain during the night. Battery settings correct with all battery savings on. Most often I even enable flight mode to save power.
When checking what have caused the battery drain, and I put all those percentages together I don't get a number that is nowhere near the actual battery drain.
So something is clearly wrong and some process is draining the battery that doesn't show up in the list of apps battery usage.
Thought it was just me!
This is very interesting.
My wife got hers about 2 weeks before mine arrived.
She's an English teacher and uses it anything from 8 to ten hours a day. High brightness, keyboard case attached.
She gets around 3 days usage before she needs to charge. (Primarily uses Dex)
Set mine up, and I'm charging every night! Stand by drain is shocking compared to my S10+
I'm going to wipe it and slowly check battery differences with any change I make (app installed, setting changed, environment changed)
See if I can isolate what's causing it.
It used to be pretty decent here but lately I've been having some insane battery drain issues. It started when I switched to the book cover, so I'd say GiantAxe is right on the mark, shame on you samsung..
Idle drain is all good here, nothing out of the ordinary.
Idle battery drain is really getting on my nerves!
Initially the I didn't really notice the overnight battery drain, as I'm never used to looking at the battery of my devices every morning. But one day, a drop of 50% did strike me and since then I'm just developing kinda OCD over this issue . It's pretty random too, 2 to 5% an hour. I've tried restricting background use for most of the apps and it still persists. Nowadays, its like I pick the tablet only to check the battery percentage and nothing else! Very frustrating.
I'll keep experimenting like all others and post if I find a culprit.
I hope we'll be able to close this thread with a solution!

Same here... Was great for the first 3 weeks, even with book cover. Then since Wednesday last week it went crazy and battery dies, no use at all, after two days stored in my backpack during the weekend. I hope this is a software issue that can be fixed via an OTA.

I bought my transformer and updated it to 3.1 on day one. So I don't know how good battery performance is in 3.0. But after updating to 3.1, one day stand by drops the battery level to 50% with wifi on. Is it normal?
That would seem normal to me if you're leaving your wifi on all the time. Really it all depends on how many background services you keep running while the device is in standby. In my case when I first got my TF, the wifi was never set to turn off while in standby, so all of my accounts and application synchronization continued while the screen was off. My battery typically lasts about a day or two if I allow those services to run when the device is not in use.
If instead you turn off the wifi, sync, and even live wallpaper, you should be able to get a few extra days of standby time.
Normal for me is 3-4% drains overnight with wifi on. Sometimes it will drain ~20%, and goes back to normal after I reboot it. Must be some rogue app or something causing problems.
It lasts a lot longer if you turn wifi off.
Better yet, check out JuiceDefender. It has a free version and paid versions that give you more control/settings. Try the free one. If you need better control, then buy it. I don't buy lots of apps as usually the free ones do it for me, but it really works well.
The only other app I bought was TitaniunBackup (for my phone, but as it turns it, once you root the TF, it works there too.)
Other threads already started here seem to indicate that while docked the TF will drain at around 5%/hour while in standby (wi-fi or no) and 2%/hour while completely turned off.
This is not the case when the TF is not docked so this is not necessarily a question of having wifi on or rogue apps.
I would not consider this an acceptable drainage level. Hope Asus is looking at this problem and a firmware update will fix this...
Otherwise, very satisfied with the combo.

yeah, I was expecting much longer stand by time even with wifi on from a tablet. Asus should fix this to be at least close to what ipad does.

Others may correct me but I think the standby time with wifi for the tablet is ok. The battery life is a problem only when the TF is docked.
Nothing wrong at all with the battery life, not sure where Asus are getting their 8 hour battery life from, I have far exceeded 8 hours and have currently been going over 5 days (still with 20% left)
i think the battery life is based on playing 720p video at a certain screen brightness(60 nips or nits i think but i have no clue what that means) of course you can get more life depending on what you're using
and i guess everyone has different opinions on acceptable drain but i wouldn't expect my laptop to last more than 2 days if its internet connection is on and sync'ing so why expect a tablet? laptops(that i've used) shut off connections and do nothing when left alone to save battery
people who need their tablet to last for days while not in use(or very minimal use) should just turn off wifi(or turn off the tablet) when you're not going to use it for hours... or leave it charging
Concerning battery drain of the keyboard dock when the tablet is sleeping:
There is a setting SCREEN>MobileDock Battery Saving Mode.
"Disables wake-up function on keyboard when the device is asleep to save more power"
I have to assume this setting should be checked. If not, that may be why your battery doesn't last long when asleep.
Asus states 9.5h (9h30m) battery life on tablet alone, see bottom of this page, *1:
http://usa.asus.com/Eee/Eee_Pad/Eee_Pad_Transformer_TF101/
they tested 720p video @ 60 nits (lowest screen brightness), I think with wifi on.
prior to 3.1 update I've been getting 9h15m to 9h25m per charge.
I use the TF for 2-3 hours at a time and shut it off (not put to sleep) when not using.
since 3.1 the best I got was 8h15m on a charge (same type of use as before).
I went through TF settings, i monitor the apps, got rid of all my Widgets and still am getting over an hour less per charge than before 3.1 update....
there has got to be some kind of a bug in the new release.
granted, there are some welcome improvements in 3.1, but this battery life issue bugs me
I hope Asus fixes it in the next update.
no1
I really hate to be "that guy", but who cares?
As long as it lasts through a day of normal use, you charge it at night, and that's that. I never understood the obsession with "My device gets 5 days without a charge!" Good for you. Those of us who have electrical outlets only need 1 day. Unless you're doing something special that requires you to be away from an electrical outlet for several days at a time, it really shouldn't matter. If that is the case, it's probably your responsibility to look into ways of saving power.
Cutting WiFi while inactive is one solution. Keeping it charged while idle is another.
Stand by doesn't mean 0 battery is used, it means less battery is used. I'd say 50% is pretty decent after 24 hours of inactivity.
Hi everyone
My question is for techy people in this forum.
According to you why standby time of TF is so bad when compare to ipad2.
Is this software or hardware related problem?
Is it fixable?
Thank.

Software problem, IIRC mainly related to the keyboard dock (dock will drain battery when it should be asleep). I still get several days of standby time, which is far more than acceptable. I don't need 2 week standby .
This post needs to go in the proper forum, however.

Sorry, I though this is related to development.
So you are saying that honeycomb is bad by design to battery? Because all honeycomb tablet have the same problem.
There is some thing about standby mode that consume for power than ipad, but why?
It is nice that the tablet does not run out of battery when you really need it.
After leaving my Transformer untouched for about 4 days last week, the battery was sitting in the 80-ish percent area. Seems like pretty damn good standby time to me.
Standby time depends on whether you have the pad docked to the keyboard or not.
If you keep the two separated the standby time is pretty good although I haven't timed it.
If you keep the tablet attached to the dock then standby time for the dock is greatly reduced as it seems to keep charging the tablet until it drains to zero even if you started with a fully charged tablet. It is a very annoying problem that no-one seems to have found a cure for yet. If you let the dock discharge fully some people have found it impossible to charge again.
I am comparing TF and ipad2 without the dock for the obvious reason.
And how long is the iPad 2 standby time?
After using a HTC Desire with poor battery life for the past year I find the standby time for the Transformer to be fantastic. I'm able to use it a bit each day for at least about 5 days. Nothing heavy, but the fact that I can pick it up after a few days of no use and it's still got a decent charge is impressive to me these days.
never used an ipad/2 for extended period of time but stnadby time on the asus is pretty good. what i find helps greatly is if you plan on leaving it in standby for a awhile, then its best to turn off WiFi as it'll help save battery life even more.
i had it fully charged this morning and unplugged it to take to work. Unplugged it around 730am, powered it on and turn off wifi and let the screen timed out. Finally turn screen on at like 130p and the battery still shows 99%
My stand by time was horrible on stock 3.1 I don't why. Once I rooted and installed Prime and OC kernel at 1.2ghz I get much better standby time. Almost comparable to my Ipad 1. Battery life seems to be better too as compared to stock 3.1

let the wifi shut off when the tablet goes to sleep, it's something iOS does by default and turning off radios will make the battery last a lot longer.
also, if you are going to leave wifi connected, the less widgets and applications you allow to pull data (or adjust the intervals they are set to sync), the longer your battery will last. iOS also is a very passive OS so when you put an ipad to sleep, everything is basically shut down, android allows apps to keep running if you have set them to sync data (ie, twitter, facebook, etc) which will also consume more battery.
the dock issue is an issue. but undocked, mine will last a week or so with light/moderate use, then again i generally charge it at night anyways.
and yes, this should be in general section, it has nothing to do with development for the device, you are asking a general question about the device/platform.
I just took my transformer on a 5 day trip, fully charged to start with, and i didn't bring the charger. I probably only used the tablet 3 times for 15 minutes, and the rest was standby. When i got home and plugged it in, it was down to 2% battery, just about to die. That is just unexceptionable. And iPad 2 under slimier circumstances would have consumed maybe around 20% of it's battery life?
I read somewhere that the new samsung galaxy tab 10.1 is rumored to have up to 75 days of stand by. I don't believe that at all, but if they are claiming that, i would assume that i would last much longer than 5 days. (plus i played with one the other day in best buy and it just feels awesome in the hands)
conclusion: hopefully future updates will help out with the transformer's battery life and stand by time.
Thread re-opened and moved to General.

Which is your WIFI policy?
I have it on WIFI off when screen off, and stand-by time is pretty good. I guess that if you need WIFI always on it will adversely affect your battery usage.
Regards.
Its not a Honeycomb issue its a Asus issue. I have a Samsung 10.1 and the stand by time is much better then the Asus. The stand by time for the 10.1 is about 7 hrs and it eats up only 3%. Also, the wifi policy on the 10.1 is set to stay on when it goes into stand by mode. My TF wifi policy is set to turn off when the screen is off and it still eats more battery life then the 10.1. I pretty much have the same apps on both tablet.
Yeah, I have mine set to turn off the wifi when the screen is off (pretty sure this was the default setting), and my standby time is much better than I was expecting (as per my post on the first page). Given the drain I've experienced, I'd expect it to last 2 weeks or so on standby, which seems pretty good to me.
It could be that your wifi disconnect policy is not set to go into standby when the screen goes off. Don't worry, it waits 15 minutes before actually turning off the antenna. But there is a bug where it defaults to "Never" after being charged (including the dock), or after a reboot:
http://code.google.com/p/android/issues/detail?id=16720
I get a few days out of mine, but I don't give it much chance to be standby, I use it regularly in the evenings.
Hi,
I am sorry, I think I didn't well explain it.
It is the fact that TF has less standby time than ipad2.
But, my question is more about Technic.
Ipad2 does email sync with wifi always ON beat TF wifi off.
But why? There is some app working in background? Why it need to be in standby mode?
I still hear email notifications even with Wifi policy set to turn off when screen is off. Definitely a software problem. In regards to the dock issue, ASUS needs to make some changes to Honeycomb so when it knows the dock is plugged in, the power saving features still kicks in when on standby despite the tablet being charged. It probably assumes the dock is actually a wall charger and doesn't kick in any power saving features. (default behaviour set by Google)
I think the main question in this thread needs to be why are people leaving their Transformers in standby for soo long!!
USE YOUR TABLET EVERY SECOND GOD GIVES YOU AND YOU WONT CARE ABOUT HOW LONG IT WILL LAST WHEN ITS ASLEEP

Hi Guys,
How is your battery performance going? We have three 64GB 3G Lenovo tablets in our office and we are struggling to get two hours usage out of any tablet. Even just leaving them in standby mode will drain them fast (less than a day). I have the acer iconia A500 and can leave that around for days and still have some juice when I pick it up again. Any idea why battery life is terrible on the Lenovo? We are all running different apps. Mine is pretty much just running stock with a few ebook reader apps.
Cheers,
SB
Something is wrong with them if the battery life is that poor. Presumably with the hardware if you're running things mostly stock. Strange, though, that it'd be all of them and not just one. Mine gets 8 solid hours of medium to heavy use, no sweat, and other people have indicated theirs get about the same. You might want to contact Lenovo's tech support (though just a word of warning, they have kinda lame tech support nowadays...).
I've got a 32GB no 3G tablet that continues to surprise me with it's battery life. I'd read plenty about folks with crappy recharge and usage times.
Mine will still have the same charge the next day if I don't put it in the dock and I generally get 7-8 hours out of a full charge, even over the period of a few days.
The old 'cell-standby' battery drain disappeared a while back. Don't know why. Don't miss it at all.
Under normal use for me (sketchbook pro, browsing, and an occasional game) I get about 8-12 hours of use (basing that on the screen on %), with 3-4 days between charges. Something is certainly up with yours, what is listed under settings>about tablet>Battery Use?
Info
Tablet 1:
Battery 69%, 7 hours on battery, maybe 20 minutes use. (Mobile broadband turned off)
Screen 39% (on auto brightness)
WiFi 26%
tablet Idle: 23%
Cell Standby 7%
Android OS 7%
The other two are not available, but as a colleague ran out the door, he mentioned that his cell standby was 33% despite mobile broadband being turned off.
Thanks for your feedback so far.
Mine (16GB version) lasts for 4 hours when it's REALLY busy, that means when I stream videos over wireless.
Otherwise...after a full day of normal usage I'm back from 100% to 40%.
Anything else I think is not acceptable..I suggest you guys have your tablets replaced.
Wait, I just had a thought. Are you guys using the keyboard folio with the tablets? If so, there's something you should know. After putting the tablet to sleep, you can't close the folio for another 10-20 seconds afterwards. Otherwise, the optical trackpoint ends up detecting motion from the tablet being on top of it and it wakes the tablet up repeatedly while the thing is sitting closed. So you have to put the tablet in sleep with the folio still open, let it sit until it goes into deep sleep, wave your finger over the trackpoint to make sure it has (after 10-20 seconds), THEN close it up.
my battery is good on standby (with wifi sleep).
Your battery drain is because of cell network. use airplane mode !
I RMA's 2 of them with the same symptoms, took all day to charge, discharged way to fast they ended up having both bad motherboards and bad batteries. I called up lenovo sent them in and had to wait about 3 weeks for the parts to come in, but they have been working incredibly well now.

That sounds very similar to the three we have. 6-8 hours to charge. Less than an hour of use to discharge. Less than 10 hours on standby to discharge. Lenovo suggested a factory reset (ha ha) to fix the problem. I'll humour them for the weekend.
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 Samsung Galaxy Tab S4's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.
Then, drop a comment if you have anything to add!
With Wifi on and Blue Tooth on, was very decent. Averaging around .42% (30.9mA) or less per hour, and last night I think I really did well at only 2% decline over a 12 hour period.
I'd say battery drain is fairly good on this device.
On airplane mode there is virtually zero battery drain. It doesn't lose any % over the night
First time I bought Tab S4 for my wife (64GB version) I turned on Airplane mode then turned on the WiFi + connecting it to my home WiFi.
It stay on standby for 10 days straight & when I checked it still have 50% battery.
I didn't test my Tab S4 256GB version though.
Mine is just draining like crazy even when I am not using it. I've had the tablet for 7 months now, and battery started to drain while unused last week. Let's say I have 100% charge when going to sleep and wake up with 60% of charge remaining. Before, I would drop only to 98 to 97% percent. Anyone with this issue? Anyone solved it? Shall I return the tablet?

Well first off.... I don't think you can return a tablet after 7 months of use.
Second, you said it started recently. What new applications have you placed on it? Updates to applications included. If you have something that monitors the battery drain per application that would be helpful. Since its new you could upgrade your tablet to the new Pie update might help out.
Personally I have had nothing but great luck on my tablet.
I've got the same problem. Brand new S4 LTE on ATT. sitting in my bag, unused, its draining 5% an hour. So I enabled Airplane Mode to cut the Mobile Connections and BT then enabled Wifi Only. Overnight I lost 20%. I'm going to run a new test: Charge to 100% then let it sit for 24 hours in WiFi only and see what happens. I may give a factory reset and set it up completely from scratch to see what happens. If it continues, I'll sell it and Get a Huawei MediaPad M5 Pro. My last 3 phones have been Huaweis and I love them. I like the UI on them and adaptive Power saving is stunning. And Huawei has the in my opinion the email and calendar app. They are linked and I can turn emails into calendar appointments. Thought I was going to Love this S4, so far I only like it and the battery issue is really irritating me. And mine weighs in at 516grams to a claimed 483 ....
No probs here, best tablet ever even comparing to iPad.

my tab S4 is 3 month old and it will only do 5 hours web surfing on wifi. previously it used to last for more than 10 hours. I tried to factory reset, it didn't work. then, I tried updating to pie and it didn't work either. any suggestions
One week of standby use all the battery (with wifi on), it's normal or I have some drain?

I have the same problem, no clue how to fix this. I'm looking for a good iPad deal now...
Made an BetterBatteryStats Dump but this shows no problems: https://forum.xda-developers.com/showpost.php?p=80827125&postcount=36696
A few days ago I had battery drain too. It was related to Samsung Internet. Uninstalled and reinstalled it and the drain went away.
I'm getting some drain from time to time and the cause seems to be the smart scan (Iris+ face unlock), sometimes it crashes and the processes are stuck running constantly in the background.
The kernel wakelocks according to Betterbatterystats are "video6" and "video5"
And the process that is running in the background is "[email protected]"
A restart solves this drain but eventually it'll come back.
I also had the drain issue after the pie update. I installed WiFi automatic after realizing the drain seemed to be related to no option to allow WiFi to turn off when tablet asleep. I have now set it to turn off 2 minutes after screen off. Just went 20 hours of standby losing only 2%.
I also have a standby drain issue, but it even persists when the tab s4 is powered off. I was away for about 26 hours and I charged the tablet and turned it off before I left. I also unplugged it. When I got back, it was down to 49 percent, after sitting off for 26 hours. I'm not sure what's causing it. It's only been happening for a few weeks or so. It also happens when the tablet is on but in sleep mode.
Battery life in general seems to be worse overall.
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 Samsung Galaxy A71's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.
Then, drop a comment if you have anything to add!
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.

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.

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.

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

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.
