Is anyone else having huge issues with battery drain after updating to 5.1.1. I've disabled all the crap, wiped my cache, disabled enhanced LTE. and have minimal apps installed besides stock. Just took the phone off the battery charger. It was at 100% when removed. It's been sitting for 40 min with the screen off. The battery is down to 93% already with 3% being used by Android system, 1% by system UI, and 1% by Android OS. This is nuts. I can't even get through 1/2 a day of regular use. Any ideas?
Big time. My phone isn't going to sleep. My Android System Stay Awake time is more than double my screen on time.
I'm having the same problem. I currently have Location History turned on to get more surveys on Google Opinion Rewards (I could turn that off if I wanted to); and I also know that because I'm not in WiFi during the day, the Lollipop mobile radio active bug keeps the radio awake way longer than it should. It's crazy that I can leave my phone alone during the day and watch it drop ~5% an hour because of the horrible standby behavior.
There is something wrong with your phone or app. I have about 100 apps. No problem here.
This is the international version of the phone

Or it's something to do with the AT&T version of the firmware as yours is an international version and not having issues.

Battery drain issue is related to the AT&T 5.1.1 firmware.

Complaint to att to stop messing with a perfectly fine phone. I haven't turned anything off and that's my idle time.

I guess it might make sense to stay on 5.0.2 in hopes of a future bootloader unlock and to stay away from a potential battery draining bug. If only AT&T would embrace a more open approach to this model phone. I only got this phone because the nexus was out of stock and I was in need of a new phone. My trusty old S3 was a godsend, with its unlocked bootloader and fully open platform. The fact that AT&T is closing up the ability to root the phone is drastic enough, let alone introducing bugs that make you want to throw the phone at the wall (battery drain).
How can I see what is keeping my phone awake without root? It's staying awake 3/4 of the time and below is a shot of my app usage. What I can tell it's a system issue, but not sure. And yes I factory reset twice and wiped cache.
Same here. factory reset cache wipe x2 and have everything non essential disabled. It's driving me nuts! This phone was a rockstar until this update. Going to best buy tomorrow and will see if the Samsung folks can reinstall the update or something. I'll post what I find out.
Battery life is worse than my old s4. The screen barely takes any of it, when it used to be more than half the battery life on my s4. Yet I still get about the same screen on time.
Yup I completely agree. Left my phone at 53% overnight and I woke up to the phone completely drained and dead. It's ridiculous.
I noticed something odd. On wifi, battery life is great, maybe 1% every 2 hours idle. But without wifi, battery life goes down 10% an hour idle.
Finally made it to the Samsung center at best buy. The guy was able to force the update again and everything went smooth. So far maybe a little better, not sure yet. I'll post when I know for sure if it worked and was a bad update.
So after the forced re-do of the update it wasn't any better. List 20% at night with everything off. Dido another factory reset and cache wipe and that seems like it might have fixed it. Only 4% list last. Not as good as it was but definite improvement. Hope this helps anyone else with same issue.

TurboRZR please update... would love to know if that fixed it before I wipe my S6 for a second time.
I too am having an issue with the new 5.1.1 update where my "Android System" is getting stuck in a stay awake loop draining my battery. Sometimes a simple restart will fix it for a few hours, but it will always come back.
I installed wakelock detector and set it up to run on a non-rooted phone. When I pulled the statistics , the biggest battery drain I had under "Android System" was diagnostic.client.network. Nothing else even came close to the drain this resource was pulling.
This was as far as I was able to get as I have no idea what that is or how to disable it if I even should.
I have resolved the issue on my S6 Edge, I even attempted a factory reset which didn't resolve the issue. I had noticed my Wifi usage in GSAM was very high (50-70%) and after some searches I found that someone else posted in a different forum (I think it was the S6 Active forum) that the issue was related to multicast being enabled on wifi routers. I disabled it on my fios router (it's in a hidden menu) and it resolved my drain. I am now at 12 days uptime without a random drain. I also had to disabled Enhanced LTE as that was causing a HUGE drain at times when I didn't have LTE. I hope this helps.
I'm having an issue with my Galaxy Tab S2 (Nougat 7.0, international unlocked T710 Snapdragon) when using any bluetooth device with it. The battery drains like hell. After a two or three hours of using a bluetooth keyboard, bluetooth is the main cultprit of battery usage. I don't know what to do - I wiped the cache partition, did a factory reset. Nothing helped.
Otherwise, the battery life is great, but as soon as I connect it with a BT device I can see it dropping. Everytime I click on Bluetooth in Battery settings I can see there's more mAh used...
I would appreciate any help.
Nougat.. thus better downgrade to MM or Lollipop.
Dear all,
I Have same bug with My SMT-813 since update Nougat, When I use with skeaper bluetooth.
Do you have found a solution?
Did you factory reset after OS update?

Dear,
Yes, all reset.
I think it's Nougat because with android 6.01 all is ok.
So better downgrade back to 6.0.1 then.

Yes, it's happening since the Nougat update. I've already filed a bug report for it but got no answer from Samsung till today.
The only thing you can do about it is to turn it off. And if you need it you have to downgrade to MM.
Same here on t819, but its kind of fake data, in my opinion there is somrthing wrong in calculating mah consumption. My battery still lasts the same, even when using or not using bt, but it has a lot of bugs, like forgetting paired devices or failing to pair. Everything about bluetooth is not perfect on N
Hi All
Do you have news about this bug?
Workaround
I've had the same battery drain issue on my S2 since upgrading to Nougat. Yesterday however I found I could 'fool' the system by turning on Flight Mode and then turning BT and WiFi back on - Consumption back to normal! It looks weird having Flight Mode on at the same time as BT & WiFi but it seems to work.
Update
I’ve just been trying to repeat my observations and the results are a little ‘challenging’
I saw a comment in another forum where someone suggested that the discharge effect is really a false positive caused by a faulty battery monitor in the Samsung software. So a downloaded a third party battery monitor, I charged my tablet to 100% , turned off flight mode and turned on both WiFi and Bluetooth.
The main observation is that the battery was not discharging rapidly – previously you could virtually watch the percentage on the battery meter decreasing in real time. After using the tablet for a day or so for browsing and watching some short videos I compared the two battery monitors – the Samsung monitor showed the battery down to 40% - but ascribed virtually all of the use to Bluetooth! The third party monitor showed a sensible mix: mostly browser and video player with small values for other programs.
I conclude therefore that the Samsung battery meter is definitely very broken.
As far as my earlier observed battery drain is concerned there seem to be two possibilities:
1) It was truly the Bluetooth causing the drain and switching to flight mode has cleared it (unlikely in my view)
2) The drain was caused by something else but was displayed by the battery meter as Bluetooth, and when I switched to Flight Mode it stopped - either by coincidence or because the Flight Mode really stopped the drain.
Number 2 seems to me the most likely explanation. I have noticed that all of my Android devices exhibit anomalous battery drain about once a month, and a functioning battery meter shows this as Android System usage. I don’t know what it is doing but my best guess it is some sort of file scan/verification (or maybe just harvesting data!). After a system upgrade it would be quite plausible that Android wants to scan the new installation.
I have, in the past, stopped this Android process by rebooting a device, so it is not impossible that entering Flight mode has had a similar effect.
For the moment my S2 seems to be using a sensible amount of power – both with and without Flight Mode - albeit with useless reporting of the details by the Samsung monitor.
My phone got the update to Android 9 a little over a week ago, and since then it has been losing battery like crazy. For example, last night I left it unplugged as a test, and it lost 30-40% of battery within 6 hours (while I was sleeping). Before the update, a fully charged battery was able to last for two days, now it doesn't even manage one. The phone is often noticeably warm.
I restricted all "consuming apps" some days ago, that did not make any difference. I also tried 3rd-party apps to analyze the battery consumption, but did not find any way to figure out what consumes all the battery in the background / while the screen is off.
Using Google I found other people with the same problem, but I did not find a solution. What can I do?
I had a same kind of problem but it started a few days after a manual update flash. I had been experimenting with some root stuff (mostly magisk though so they should go away by uninstalling the modules) but could also not figure out the reason for the drain.
I also tried to reflash only system and vendor partitions, but ended with a bootloop, so I had to flash the whole firmware again. No problems after that.
I would try a factory reset if I were you.
You can also try GSam battery monitor (if you already haven't) to figure out what's happening with your phone while the screen is off and it should be sleeping.
I upgrade the XPZ yesterday to 4.41 Pie. Charge the mobile after upgrade to 100%.
The current situation looks like:
18hour active, 30 Min Display, a few calls... Whatsall, newsletter, Mail..... are running in the Background, LTE, EDGE and WiFi are always on, BT has a connection to my watch...
88% are still in the Accu. (Save mobil datatransfer is aktiv; additional the option is enabled to reduce power consumption for apps in background)
Hello, I am new here and couldn't find anything similar in the Mi A2 forum about this battery drain in Android Pie 9.0.
I bought the Mi A2 128gb/6gb two months ago, and since yesterday I realised an abnormal battery drain. When I went to check it out, 37% of the battery was spent in the mobile network standby. Today, after 3 hours of use is around 15% already. In my use, I get between 3 to 5% per hour, now it is between 6 to 10% due to this issue, is infuriating for a phone bought two months ago.
I've been since yesterday trying to find a way to discover the cause, I use 4g LTE most part of my day and the signal is good, urban area, in both sim cards.
Haven't used any custom rom or anything, still standard from the global version, did all the updates, including the latest February 25th. I don't think the update is responsible for that, but it is the only different thing I've done in the last weeks.
Have tried several solutions suggested for others xiaomi models but nothing seemed to work.
Did anyone experience this? Does anyone have a solution?
Yes that is pretty strange. Mobile network standby shouldn't be using up that much battery. Try rebooting the phone to see if it resolves. You could install 3rd party apps such as Greenify to monitor background apps more closely/hibernate them, and Naptime which uses aggressive doze to make sure you get better standby battery life.

Download cpu spy and check if phone enter deep sleep, there was a bug some time before with the cpu stuck at 1401mhz.

Thanks for your answer. haven't tried yet rebooting the phone, I did just the network reset and haven't changed a thing.
I downloaded greenify, but haven't quite used because I can't identify an specific app that is causing the problem.
I am using Greenify, Accubattery GSM Battery, CPU Spy as well.
A strange thing is that the excessive battery drain is allocated in some apps.
Usually, in the android battery use, it shows whatsapp and/or instagram are using the most battery, but when you ask the full device, is when it shows the mobile network.
In the GSM Battery, it says the battery used 12% while turned off and 5% while turned on. It makes no sense.
The only thing I could realize is that when it does get in sleep mode, the battery drain stops, but as soon I start to use it again, it returns to happen. I am afraid is a hardware problem.

Thanks for your answer. I downloaded and monitored for today, most of the time it stays in 633MHz, and Deep Sleep. Both together are above 70%.
I don't think is a CPU problem. I am afraid is something with the antenna
I have an update.
I usually use LTE Network most of my day, today I managed to use wi-fi and the problem is not happening.
I suspecting is either an incompatibility with the Mi A2 network. But my girlfriend has the same phone, but the 64/4gb version and is not experiencing this problem, or and hardware problem with my antenna.
Nobody else has experienced this?
So, It has been 10 months of headaches. Bought in july 2019, for two months best phone ever, battery lasted 2 days, near to 1-2% of battery drain at night on standby. After installing miui 11, the battery said "bye bye". 3h screentime, need to charge the phone twice a day, losing 10%/h on standby.
What I tried is:
-havoc os
-xiaomi.eu Miui 11-12. beta and stable
-Evolution x
-latest firmware always/reinstalled latest firmware-vendor
-always clean install wiping everything
-new battery 2 months ago (same results, no difference at all)
-no app is draining battery in the settings
-unistalled analytics and miui daemon (msa not found on xiaomi.eu roms)
the phone goes in deep sleep as you can see in the photos in the link below.
Gps, wifi and bt always on. Tried switching them off, just 1% less of battery drain on standby.
Bought a broken mi 9t pro just to try switching motherboards, just to try that it isn't a electric or physical issue with the phone, but can't do it that right now, waiting the new screen to test the broken phone.

Any suggestion?
Have you tested putting the phone on standby in airplane mode? This is unlikely to be the root of the issue but poor cellular signal may negatively impact the battery life.

tried that also, nothing change. Always 4%+/h of drain in standby.
I've pretty same problem, and it's really strange...
I've a Mi 9T Pro, bought not more than 2 months ago brand new, all stock.
I leave on just the phone active during the night, in both SIM cards: no bt, no wifi, no mobile data active.
The battery drain is around 10%, which is really insane considered that before my 3 years old phone, an Honor 8, in same conditions, was draining not more than 4%.
In general battery is draining really too much.
Passed OTA from MIUI 11 to 12, but the drainage is same.
I'd like to understand what is the issue causing that.
Dude. Same issue for me. It's only 6 months old. I noticed battery loss on miui just a month into purchase. I'd suggest pick a rom without Gapps or one with microG and try them out. I was using evo X and getting around 6-7 hrs SOT. Once I moved to Aim and Omni I started getting 9-10 SOT. I think Gapps is mostly the culprit. Miui sucks these days. I tried miui 12 and was utterly disappointed. Try this and you might just start loving your phone again. I'd say go for Omni and setup microG, install greenify, turn off battery optimisations only for essential messaging apps and turn on aggressive doze. Your sure to see a difference
Try havoc os 3.7 , try it without social apps like instagram, facebook and other crap.
Mine usually lasts around 3 days with 6h sot.
I also have gps , bt , sync and data always on
Tried gms doze? Disabling autostart of apps in miui?

The point, guys, is not to try different ROMs or install apps or not to use social medias because the phone drains battery...
The point is that the phone should not drain battery that much at all!
I think Xiaomi should care more of the firmwares released, trying harder to fix bugs that might be important rather than releasing new features.
My own opinion.
PS. Last night i checked the battery drain thoroughly: from 1.30 am to 7.30 am, just both SIM cards on to receive eventually phone calls, no WiFi, no BT, no internet connection, ND mode active = battery drained 9%
It is not acceptable!!
Clear all apps from memory, clear cache of 'Google Frameworks' and 'Google Play Services' don't restart the phone
I do this whenever I remember usually every few days and get great SOT around 9-11 hours. Although Accubattery says my battery health is 3300 of the 4000 as I've had it for a while and I'm a very very heavy user. Brand new was getting closer to 10-12 hours doing this same method.
I found it by someone posting a random comment somewhere in this forum just don't know who or where I saw it. They gave no explanation as to why it works but just what they did and its worked immediately. Note I'm still on MIUI 11.0.3 Global as I'm nervous this method won't be as effective in more newer MIUI Versions.
If you have a newer version please try and let me know if it still works, hope this helps
Also I reinstall MIUI through the phone after clean flashing it via Mi Flash
That is that I flash clean (erase storage but not lock bootloader) from Mi Flash and then go to the update settings of the phone and then press the 3 dots at the top left and "download latest update" and then install it again
This helped when I was on MIUI 10.X.X but do it out of habit so not sure if it helped for MIUI 11.0.03
edit: Reinstall method
Similar issue with my K20 Pro.
1. The battery backup on Android 9/MIUI 10 was giving me close to 1.5 days of backup of 7-8 hours of screen time.
2. It was decreased to 6-6.5 in Android 10/MIUI 11
3. Now with MIUI 12 it is reduced to 6 hours and with need of charging two times in a single day. All this with no social media apps, only Whatsapp, Youtube, Prime Video, Spotify and MS outlook, teams apps with regular usage. WIFI all the time, no GPS, 2-3 hours of Bluetooth. plus tried deboating MI apps.
So far I have tried PE, EVOX and EU roms but all gave me disappointing battery backup. The battery seems fine only on android pie so my assumption is that battery probably doesn't need replacement and more of xiaomi's firmware related issue on android 10.
It's so disappointing to see such a great piece of hardware holding back because of battery. I hope somebody find a good solution to this issue.
