Right, no matter what, I'm getting battery drain in stand by. No sync, Google now disabled, no mail, no location reporting/history etc. and yet I'm getting weird battery readings. In the pic below you can see, I'll let it idle for a couple of hours and the battery will drain. Then I'll use the n10 and the levels will spike. BBS shows that the n10 is awake for about 4 hours but the partial wakelock and kernel wakelock nothing untoward. I'm reluctant to root as I dont want to void my warranty but is any one facing similar issues?

You can unroot and relock your device. Rooting should not be a warrenty issue.
See: " [NEXUS 10 TOOLKIT V1.3.0] Drivers, Backup, Unlock, Root, Flash, Mods + MUCH MORE"
http://forum.xda-developers.com/showthread.php?t=2001868&highlight=unroot
Features mentioned among many: "* Unlock/Re-Lock your Bootloader"
You will not lose warranty just by rooting the tablet. Nexus devices are pretty much made to be unlocked and Google provides the tools themselves to do the unlocking. I have heard of other people get warranty stuff done even while their tablet was rooted. This is because warranty is for hardware defects, which are not caused by root. If you have software problems then yes, those are to do with rooting. But normally you can fix software issues simply by finding a better ROM that has more bugfixes.
Also, that is some really terrible battery life. My tablet loses 1% every 7-9 days while idle. CM10.1 ROM from CraigGomez (November build) with KTManta kernel.

Is it worth getting in touch with Google? I've had it since just after xmas? I'm about to factory reset it for the second time this week.
Why do you need to factory reset it so often?
I would root it, install a custom kernel, and run better battery stats to try and see what exactly is causing such a huge idle drain.

I'd rather not factory restore it, this is my second time doing it. I'm starting from the beginning like it's a fresh install, just using the Google apps only to see if there are issues there and then adding more until I'm comfortable.
I want to root the tablet only as a last resort as I'm attempting to see if it is an app or it is the battery. I'd rather not brick it or void warranty only to find out it is the battery and then be unable to get a replacement.
There must be somebody that has similar problems?
So, factory reset, this is after 24 hours; This is not kosher. Stock apps. Only thing syncing if you can call it that was Google now. No syncing or anything. Purely from stock apps with updates. Stock battery graph says that it's not awake but stats say it's awake for 19 hours.This doesn't even come close to advertised idle/stand by time. Surely I should return it? I was adamant that I wouldn't complain but I didn't pay so much money for it to come out with this as stock performance.
That is massive usage from Android OS. Something in there is causing a wakelock, which means it is probably a software problem. If you were rooted and had better battery stats installed then it would tell you exactly what the wakelock was from. The built in Android battery info just gives it a generic "Android OS". It looks to me like that sudden sharper downhill slope is the point which the wakelock started. Although that is a bit steep drain before that point too. The point before the sharper decline section looks closer to a non-deep sleeping device stuck at its lowest frequency, but it had to have been sleeping if the device says it was only awake for 14 hours. Still, that 14 hours is a wakelock. Probably from the kernel. Cant say what it is exactly unless you have a better app installed
The Google Services thing is probably Google Now sucking up battery. It tends to do that.
You can either continue to diagnose this problem from the software/firmware or you can just send it back if you want.

Thanks. To be fair I think if purchasing such an item, you shouldn't have to become a developer/hacker to study such an issue. Haha! I've used Google now when I first got the tablet and not understanding what it was had it enabled and get there was no battery drain to such an extent.
Fair play to Google, they've agreed to send me out a new one. It reached a point where I couldn't enjoy using the tablet and everything was a test to see what could be causing the issue.
I won't bad mouth Google, as I understand that things do become faulty and these items are complex enough. On another note I called up the RMA team in American (I googled the wrong number) and the two ladies were more than helpful. I don't know how anyone has problems with them. Maybe it was my British accent that did it!
So, I've got a replacement and so far it is not displaying the same issues. It got me thinking about when my original problem started and I think it started when it was updated to 4.2.2. This model comes stock 4.2.1 and it's prompting me to update. Should I bother? Was I just unlucky? Is there a specific way to ensure that the update is a clean update?

Upgrade to 4.2.2 as it's more stable, especially with the Chrome browser but there are additional bug fixes that address overall stability. A rule of thumb is to install new apps one at a time so you can judge if it causes instability.
You can also install, free from the playstore, "Bootlog Uptime" which tracks crashes and sometimes provides crash related information from the Android logs. It is very handy when you are trying to determine the cause of a force close, freezing or general odd behaviour.

Yeah, I kind of did that when I factory reset it, I just loaded up the stock apps, desynced everything, logged out of everything that wouldn't be used, disabled Google Now and location settings, rebooted and it was still iffy. Before I sent it back I left it for a day and the battery stats were going up and down like a roller coaster. Could it of been a faulty battery? I would like to update but I'm so wary of the problem coming back.

You may have been unlucky. I have had great battery on all 4.2.2 some ROMs/kernels make a difference.

So, after a few days my new Nexus 10 started displaying exactly the same issues as before and I had just about ruled everything out. I used BBS again and looked at the stats, with PowerManagerService being the main culprit but the numbers in Partial wake locks just didn't match. There were very little wakelocks but something was still draining. I looked at the CPU and for most of the CPU was running at 200hz in deep sleep. I just couldn't figure it out and looked at the Running apps and there was only a few but one remained constant throughout all my tests and that was the Settings app. I took a punt and stopped it and cleared it from recent apps. Lo and Behold, the drain has disappeared and the battery doesn't drop at all in idle.
Excuse my noobiness, I didn't know that Android treated Settings as a separate app? On my Samsung S3, this isn't the case, once you leave settings it closes it and suspends it causing no drain.
200MHz in deep sleep doesnt make sense. Cause deep sleep is different than a MHz value. If you are mostly on 200MHz then that means something on the tablet is not letting you sleep properly.

Sorry, didn't make myself clear. BBS was saying that tablet was running at 200mhz preventing it from deep sleep and that thing causing it was having the System Settings app not closing. Hope that makes sense and helps people in the future.
Well that is certainly an interesting find. If you restart the tablet and dont open settings does the tablet sleep fine?
Yes, if you restart it and avoid going into settings, it sleeps happily only waking sync if you have any. It has been idling for about 10 hours without dropping.
I've attached a picture and if you compare to the one I posted at the start of the thread you can see a clear difference. There was a point where I forgot to close Settings and you can see the drain (middle of the graph).
Somehow I don't think this is normal. It dropped almost 30% at home while I was at work. Google now is disabled but groove IP running. No apps that should be sucking battery, but its mostly the android OS. Any thoughts?

I installed Spare Parts and saw that my phone was never sleeping, even though it was on standby all the time.
This was caused by the location by antenna feature.
Ever since i unchecked that feature i've had around 50-60 hours of uptime, with a few calls and a lot of texts.
hope this helps alot others
With the new firmware the problem of battery dissapears completely
There is a known issue with network location detection in android 1.6. I had the same issue with my galaxy and it was solved. Now that we have root, we can hopefully do the same.
Also, br aware that I have found spare parts to actually stop the phone from sleeping, as well as tapatalk. I suggest rebooting after using either program.

Actually that issue is fixed in the latest update so it's already fixed without needing root.
Which firmware? I know I'm still experiencing it.
RBA020 solved the battery issues for me.
Where in spare parts does it show you if your phone has been sleeping?
you don't need spare parts. Just dial *#*#4636#*#* and click battery history and then the running bar.

I know from having a Samsung galaxy and being part of the androidforums community that was going nuts until Simone found a bug report with Google saying that network location was stopping devices from sleeping. We had root so a Dev applied a patch to services.odex and voila! Phones were napping again.

Update after turning location off completely
Well first run with all location methods disabled (I can still enable GPS quickly via a widget when I need to use it)... the battery performance is up phenomenally!!
I charged fully before going to bed last night, then kept the phone unplugged... woke up and found the battery was at 97%. This has never happened to me.
Ok, one thing tho, I use Juice Defender with night time schedule, so my wifi and 3G were off during most of the night. Anyways, its been around 3 hours since I woke up, and I've been using the phone on and off to do some browsing.
The battery is now at 93%.
I do not use any other aid other than Juice Defender... no task killers, no startup editors. Will update on how the rest of the day progresses.
EDIT: my thanks to Inebriatef and adrianoftyriel for pointing this out.

I too would like to hear a bit more. Could the OP please elaborate?
I'm running the latest FW and although my battery life increased exponentially, I find that it's not going to sleep anymore! I had close to 50 hours battery life and now I repeat everything to get just under 20 hours.
I don't use task killers and crap anymore, just before I put my phone away. If I don't, I have a trillion programs running with like 40mb of RAM free. Although I understand this is Linux based, these programs are RUNNING and not idle. All my **** is draining the battery again after a clean reinstall of everything. What a bummer.

@bongd, by latest FW, do you mean the R2BA020? If yes, then you shouldn't be affected by the problem being reported here. I'm still on R1FB001, which apparently has this Android 1.6 bug related to location.
As in my case, simply by disabling location settings (even though this reports that network location is the culprit, I disabled them all), the phone is now able to suspend itself and basically consume very little battery in standby.
Personally, I dont see any issue with lot of applications running and having little RAM left because I trust the Android system to manage it efficiently. Furthermore, the RAM on these phones is not as fast as what you would see typically on desktop systems, so it actually helps having things around in memory rather than aggressively cleaning it out. Checkout this link to understand a bit more about Android task management features: http://android-developers.blogspot.com/2010/04/multitasking-android-way.html
I suggest you use Spare Parts to isolate your battery drain, there might be some app that is misbehaving and hogging systems resources. Also turning off very frequent updates/refresh intervals in some applications is the way forward.
I found through trial and error that fancy widgets keeps my phone from sleeping.sad cause I really want to use it.

Thanks, j4mm3r. I am using R2BA020. It looks like I have some diagnostic troubleshooting to do when I get home.
Sitting here at work charging my phone, it isn't loading craploads of programs anymore. And it seems to be sleeping okay. I'll play around when I have some free time.
Fixed my problem big time
Hey guys,
I just wanted to throw my two cents into the pot.
OK – so after experimenting with Task Killers, Task Managers, Spare Parts, Juice Defender, etc. I came to the conclusion that they (for the most part) did more bad than good. It was getting to the point that I was just starting to accept that “The X10 just has ****ty battery life” end of story.
I also read in a Google released post on the web, that there are a number of reasons that Task Killers, etc. are actually not required to end tasks. Android actually has a fairly intelligent and systematic approach to killing tasks that are not being used. I haven’t used any sort of proprietary battery saver, task ender, startup cleaner, etc. and I’ve been having the best phone performance since I got the headset.
The time now (Eastern Standard) is 3:30pm on Monday. The last time I charged my phone was Saturday evening at 6pm, and currently I am showing 24% battery remaining. Let those numbers do the talking!
My settings are:
Wi-Fi always off unless I am going to be actively using it (browsing)
Using Phone info, I change WCDMA Preferred to GSM Only (enables 2g instead of 3g without disabling data altogether)
GPS always off
Screen settings, brightness, etc. I believe have a much smaller effect than people tend to believe. The SINGLE BIGGEST factors for me, and noticing this huge increase in battery life are:
Settings -> About Phone -> Software Update -> UNCHECK Automatic Search (this constantly searches the market, etc. for app updates and what not)
Cycle power immediately after charging. Once my phone completes its charge, I turn off and then on again.
I hope that some people can enjoy moderately extended battery life as I have. I am SO ecstatic to be at HOUR 43 and still at 20%+
Worth mentioning also that I am on Rogers (Canada) and have not received any updates, so this extended battery life is not a result of a firmware update.
How I Fixed My Batter Life Problem
My Incredible would run dead in about 4 hrs doing nothing. I finally dug into several "task killer" programs and found that about 20 - 30 apps were invisibily running in the background constantly. As soon as I permanently killed them, my battery life went to normal. I can now get about 2 days of normal use on 1 charge. Even a day of pretty heavy use will last almost all day.
So for me, it was all the new apps I installed when I first got the phone that were running in the background. The free "task killer" program was not showing them. I finally found the app called "System Panel." It was the ONLY app that would show me all the "invisible" apps that were still running invisibly in the background and let me kill them. Once I killed them with System Panel, they stayed dead and the free "task killer" program could auto-kill them from them on.
Not sure why the free programs could not see the rogue apps, but my battery life is GREAT now.

I'm running R2BA023 and I am struggling to get a full day from the phone at the moment. It normally lasts around 12 hours and then its flat.
However, I ran the Telenor R2BA020 update and I manage to get a full day with ease.
I have just done a clean install of R2BA023 Generic UK "root" edtion and going to see how I get on. What I did notice before is that the phone was not returning to a idle state.
My Evo battery is draining at a rate that is all together too fast. I took it off the charger about 3.5 hours ago and it has drained about 30-40%. I have not made a call nor used the net at all save for the receipt of 3-4 emails. I had a rooted phone but I reset the phone back to complete unrooted stock. I have not even so much as installed an app. What can I do about this?
turn off your mobile data when not in use. This will save tremendous amounts of battery.
if you search the forums you should find countless threads on battery and how to find out what is draining your battery and to extend life.
not sure why you would unroot unless you were exchanging it at sprint store but it greatly limits what you can do to help prevent battery drain. If you dont want to mess with much jsut use a rooted stock rom and it is pretty much the same thing as being unrooted but you keep the extra rooted benefits.
your best bet on non rooted device make sure mobile data, 4g, auto orientation, bluetooth etc are turned off. do the HTC battery condition/charge trick. and turn off background sync.
my suggestion is to re root and look into undervolted kernels and many other battery saving tricks found using search!
hopefully it helps some.
I had the same problem OP.
Turns out my radios weren't update.
Head over to the developer section and download the newest radios and stuff.
I've seen significant improvement of my battery life by using Collin_ph Battery Tweak 1 that was offered by Myn's when I flashed his/her's rom. I had my BF take his Evo to work after he come home complaining that the charge would only last about an hour or two and behold, he got through the whole day without having to charge his battery. This is after listening to music at work for 8 hours also. I HIGHLY recommend this tweak for ROOTED PHONES as I and everyone else I've recommended loves their Evo now and have no complaints...I'm at work right now and I'm at 79% and when I usually get home the battery is either still green (full) or orange (med) charge. I'm not sure if this tweak can be used with other mods but I'm very happy with this tweak as it has made my phone perfect now~~
Could be a Rogue app running killing your battery or radios not updated like stated above.
I recently started having the same issue. Advice such as turning of data and the GPS aren't helpful since the device functioned fine with GPS and data on before. Also if the battery was draining at a slower rate on the current radio before, you shouldn't need to update it, should you?
Seems that either something is making the Evo use more juice than it was before or that the battery is not holding the same capacity it used to. For some reason Phone Idle and Cell Standby have been using quite a bit more juice than they used to.
I don't like some of the software mentioned to try and locate anything that could be using more juice since those programs seem to use quite a bit themselves. Either way, what could be doing it that would come up as Phone Idle or Cell Standby in the included battery monitor? Wouldn't anything else come up under Android System?
The battery draining that quickly is not normal even with background sync, GPS (idle), 4g, data, or anything else on. There is another issue which must be solved. To troubleshoot so far I've tried another battery (same thing happens) and now I'm trying with everything turned off. If I can isolate what was causing my sudden rapid battery drain, I'll update everyone. This just started a couple nights ago for me. I think I'm on the latest radio, but I'll check.
Last post sums up my problem perfectly. I have an extended battery that lasts half the time it has over the last 4 months. Started with the radio updates. running myk
Use the battery usage functions of 'spareparts' to determine what's consuming cpu or preventing the phone from sleeping.
Can't fix the problem until you've isolated what's at fault.
Turning off mobile data will indeed fix a problem of some app trying to access the network, but it won't solve the actual cause.

I think juice defender does this automatically when the screen is off.
In the case of my phone, and I believe the OP's, we don't have any rogue apps or things running in the background. I know this phone like the back of my hand. I have completely uninstalled unnecessary apps like facebook, twitter, all things like news and weather are on manual update, i don't keep 4g or gps on, and I use wifi at home. I turn off 3g in terrible reception areas. I'm not a new user who doesn't understand the basic ways to save a little battery. I'm pretty sure the OP isn't either by his post. I use my phone the same every day. My chinese extended battery would last me easily from morning to bedtime with 20 to 30 percent to spare. Now I can't get near that after the radio updates. Since it's been well known that something is weird with these current updates, I've downgraded to 1.77 to see if that helps. My phone was sleeping fine though, so I don't know how much it will help. Always some BS with this phone.

if you are having trouble after a radio update, just try some of these other radios and see if that helps
Your best bet would be to root your phone again and give one of the SBC kernels a shot. I'm running CM 6.1.2 along with Zendroid 1.1.0 BFS AVS SBC and I can easily get 16+ hours with HEAVY use. And when I say heavy use, I mean hundreds of sms, dozens of calls and lots of websurfing. You will love the SBC kernels. Give it a try.
PS. My name is HondaCop and I approve this message.
We can offer suggestions until we're blue in the face.
First off, the OP needs to provide specifics of what's installed on the device, including rom, kernel, radio, etc, not to mention the hardware version itself.
Assuming it's not the known pri /rom conflict, then determination needs to be made as to what's actually consuming cpu - see first sentence above.
Need to use a systematic approach to troubleshoot this, otherwise it's a waste of time.

That sounds like a very weak cellular signal is forcing the radio to keep searching for it, draining the battery very quickly.
One way to somewhat alleviate this problem is to force roaming, to connect to a provider with a better signal.
"Roam Control" app does this (Market).

Sometimes I wonder how far android users went in school....is scientific method lost these days? By no means am I qualified to help here..so my flamesuit is on for the post but damn.."my ****z broke...halp" won't cut it in a developer forum...

Actually,
some android users looked at the posting date, saw that the op hasn't updated in over 24 hours, wanted to complain about it, decided against it, posted quickly the most useful idea they had.
All that while doing real science.
Hey guys, I have tryed to find same issue, but i dont seem to find anything that is exactly the same on this forum, yet i see it everywhere on the web/google.
I have a problem with my new 2weeks old note 3! It have problems maintaining a prober battery drain and its really pissing me off. I have to restart my phone everyday, its like its slowly building up overtime or overnight... mby even after i recharge it?
I wanted to post some links to my dropbox with screenshots of betterbatterystats and gsam battery, but cant right now because im new, so first up ill see if anyone have any idea without further explanation!
Im rdy to do allmost anything, but i have no idea how kernel and stuff like that can be fixed... :S
Heres some of the pictures from working and not working!

Wow that looks much better than betterbatterystats, atleast easyer to understand! seems its samsung push and exchange mail that is the top users.. Could they both go under the category as a android kernel?
if you don't use exchange corporate mail you can freeze both apks. I use touchdown app for my corporate email, so those apps are also freezed.
I use the build in calendar, and its synced with my work calendar, so i use "Microsoft exchange activesync" to keep it updated. Could that really be the killer? according to gsam battery monitor my exchange "mail" is only 0.6% battery use while Kernel (Android OS) is 28.2% then its Android-System and then rest is below 2%..
Gonna share some screenshots when its gonna be available for me! This is really annoying me, knowing the phone can easly function and have battery for 2days+ the way i use it!

When I have a battery drain the first thing I do is give the phone a soft reset. Switch your phone off, take the battery out for a minute, reinsert the battery, do a cache wipe (start up in recovery mode by press and hold VolumeUp-, Home- and On/Off-buttons at the same time, and choose "Wipe cache partition"), then reboot.
Usually that solves the problem. If not, then I will start investigating what is causing wake locks etc.
If everything fails, than I do a factory reset.
To my feeling, people in general tend to do the investigation too soon, leading to nothing and forget to do the soft reset first (which doesn't delete any settings, apps or data, so there's no reason not to try it).
I had an unexplainable battery drain two weeks ago, solved by a soft reset as described, perfect battery since.
In location services (in Google Maps) I've switched off Location History and Location Reporting, which are known battery drainers, but that's pretty much all I do to prevent battery drain. I did notice that Nova launcher takes more battery than the stock launcher, but not enough to skip using it (at least not for that reason).

Even though it don't delete any settings etc. it still helps for some time. but my mobile is as close to stock as it can be, I hardly use anything that could cause this, except if its from android itself/samsung installations. Which it seems to be!
How often do you have to do such a painful reset? in my eyes, thats something you have to do, if its Broken!
Starting to belive its exchange, mail_service.
That specific one have 92x wakes in 2hours and all most 2mins used. I Think thats what keeps my phone from having deep sleep going. but its weird cause I only have it syncing calendar, which also show as a specific thing under the "mail_service" and it have like x2 wakes and less than 2sec used...
Apparently this bug is not new! Come on google!
I have read some people having kernel problems. .. and they have fixed it with changing kernel..
Do anyone know a good kernel for note3 ?
Speeking of the devil: today my Note3 wouldn't go into deep sleep again. Solved it by again by a soft reset, but start to wonder what triggers it. In my case I suspect the Tomtom app that I used yesterday, which gives me other problems as well every now and then (e.g. when the phone goes into stand by while Tomtom is running in the background).
I guess doing a soft reset on a regular basis is something I should do to keep my phone happy. In that, smart phones are not that different from PC's, which tend to show instability after a while as well if you don't restart them regularly.
But I do agree: in a perfect world it should not be necessary.

Just to make a thing clear though, I am not looking for battery saving tips etc. that would ruin the point of having a smartphone, its all those cool features that makes it worth buying. But knowing it can work WITH all these features and Not drain the battery, makes me crazy mad(I am at the point of returning it as being "defect")! It just destroys my experience of having it when I know something is not right. And it wasnt exactly cheap..
Anyone know anything about this?? Do the Screenshots help anyone? I am so close to the decission of rooting and then change kernel and rom this weekend if I dont find out why my phone is using this amount of power, When I know it dont have to!!
I've the same issue too on my completely stock set! Can't figure out what exactly is the culprit though ...

I just got totally fed up with it, so i did a factory reset and done minimal account bindings. So far it's working! So now I will just pay super attention to What I install. So i know When it goes wrong!
having similar issues recently..
and I can't detect what's wrong with BBS either :/
I am also having the same issue with my Note 3. Always the same thing. Works OK for some time after a soft reset and then starts not deep sleeping properly. When viewing at Battery usage it usually shoes "Media" or "Android OS" or "IndexerServices" as the number one.
I am happy with my Note 3 but it is really annoying knowing that your battery is being wasted without real usage.
Have someone contacted samsung or google about this?
Nice knowing I'm not the only the one with this Android OS causing battery drain when phone is idling.
Not nice knowing there isn't a solution yet.

Lets keep this going, I am going to contact google about this when i figure out what it is, for now im just being super observing! I did a factory+cache reset this friday and now sunday evening its still working(didnt even charge it all weekend!!!)(https://www.dropbox.com/s/khjosuw9t207paf/Screenshot_2013-12-01-19-35-23.png) I havnt synced it with much yet, but I have a little bee buzzing in my ear, telling me that its very likely something with the samsung_push service/email. So atm I have NOT added any email to the phone. Going to charge it up over night, use it normally all day tomorrow AND- if it still works, ill then at evening add my work email and then do this kinda step by step and check when it ****s up. Cause who am I kidding, if I just contact google/samsung now, they wouldnt care ****.
any updates on this mystery?
I've noticed this phone has hit or miss battery life depending on what you have installed, greenified and frozen. I thought it would be a good idea to create a thread where everyone could share their battery life tips and tricks on this phone.
Below I posted what I have done to maximize battery life. I have not rooted my phone yet, so none of the below tips require root.
I disabled all bloatware apps that came with the phone. I did not disable any of the Asus applications.
I utilize the Asus autostart manger and denied auto start to all my applications except music applications, messenger applications, and google photo sync.
battery sucks. drain to much.
Just use until you have 5% free battery, this should make at least your day
With Android OS taking so much thanks to lollipop, there is not a lot to hope.
We wont see a good battery improvement until we get 5.1
Luckily, that is in the future for this device acc. to Asus.
Since the issue seems to primarily be Android os draining the battery I don't think most battery saving measures will make a difference. We will just have to wait for an update
When I was looking at the phone reviews people were claiming 8 hours screen on time, I can barely get 2 hours screen on time.
The problem I'm having is that the phone never goes to sleep and is constantly awake. Has anyone else seen this issue?

I'm on 2.18.40.12 (ZE551ML of course), I restored the phone from backup & restore in settings (It may take 30 minutes or more). Before restoring I had 45+% of Android OS during the night, now 20% more or less, but, as said, also in BBS I can see deepsleep in frequencies.
Someone posted on Zentalk to turn off remote lock and scan for security threats in google settings. Not sure if it helps or not.

Glad you solved, but don't know why, maybe they are working hard on the firmware and there are lot of changes that can cause problem, maybe we have to wipe after every update, Intel processor and Lollipop are so unstable right now!

Ok so this is my battery with a normal day of use... Tomorrow ill show the results with your sugestions. My normal days have gsm calls(normal phone calls) whasapp (chat) youtube, twich, game like plant vs zombies 2, look at gmail, surfing internet, taking pics like 25 today.
I notice that battery drains a lot more while photo app open.
I use doble sim as you can see
If you want to test app battery drain, try GSAM Battery Monitor, or for some extra functionality the Pro version. Also very useful to determine what is causing wakelocks when you run into them.

Everyone is always wondering about Android using the most battery. Without doing some in depth debugging and tracing I would guess Houdini falls under Android. Because the ZenFone 2 uses the Intel processor a binary conversion for ARM instructions takes place with Houdini. More than likely you have a lot of apps native for ARM.
Force closing asus support app and zenui services app from apps setting gives me good amount of battery boost. Apart I have also disabled google books, movies, plus etc. I don't know if its placebo effect but someone can try and confirm. These app tend to restart at times so if you feel the battery decreasing at high rates again, make sure you force close them again.
Roughly speaking, I tend to get 3-5 min per percentage of screen on time with this which totals to 5 to 6 hrs on SOT on continous usage. Without the apps being force closed, I barely get 2min/%. The usage scenarios are normal web browsing, chats etc. This is using mobile data. It gets even better with wifi.
Try and let me know if this helps.
Maybe I don't use my phone as much as other people. I posted this last night on another forum. My phone was unplugged at 07:00, It's now 21:00. I have 80% battery left and the battery monitor shows 3 days left
I have received email, 3 phone calls and text messages. I checked Twitter a couple of times with the browser. I have read Google News a couple of times and played GSN Casino for about 20 minutes.
In Auto Start Manager I turned off Docs, Sheets, Skype, Slides, Translate, Amazon Kindle, Data Transfer and Web Storage. Everything else is Allow, but I have no social networking applications installed.
Its looks like battery life is a right mixed bag. At the start of the week I was suffering wake lock issue, my phone wouldn't go into deep sleep and was constantly awake. I wiped and restored from backup which seams to fix the issue.
Got up this morning and it looks like the wake lock issue is back. I don't know what to do to fix it.
Feel like giving up on the phone and sending it back if I can
hi MI A1 owners.
for those brave enough to use the latest vanilla, official OTA rom, what change did you notice?
does the battery still suffer huge drain that appeared in 2018 roms?
it's a big "NOPE" for me to update, i'm still on official DEC rom because of this drain issue.
Battery life is good on 8.1 no issue for me getting 5-6 hours SOT on gaming.
Never had battery drain problems. Only "issue" is notification led not blinking.
Just noticed that led light is no longer blinking when notifications arrive. Light stays on only when screen is off. Also Bluetooth is constantly disconnecting.
Ambient display isn't working for me.
Led notifier is also not blinking anymore!
Led not blinking, proximity sensor doesn't work properly all the time, some scrolling lag. That's what I've got so far
dudes thanks for your answers.
i'm just more convinced to not doing the update.
maybe the drain i had was magisk-related. (?)
Nothing for me, even got ten hours of screen after some cycles. Led doesn't bother me and it's the only thing i noticed.
Yes, the LED is always on, which is annoying, but the bigger issue is there is no change in the battery drain. I charged to 100%, set the phone down and did not move it or use it overnight. 8 hours later almost 14% of battery was drained. I have tried everything I can think of to try, including turning off high accuracy location, not allowing any location things like safe area, etc. and still I get this drain even when the phone is not in use. Android kernel and system consumed 85% of that usage, and System UI, Play Store and Phone Services accounted for 7%! SO basically, basic Android paired with the A1 hardware seems to be the issue and I don't know that there is any fix for that.
At one point, I thought an upgrade to the A2 was going to be a no brainer, but with the issues with updates being broken and this battery drain issue that nobody seems to be able to pinpoint and resolve, I am thinking I may not buy ANY other Xiaomi. It may be time to try something else because the only way I can get two days of battery is to turn on airplane mode when the phone is not in use!

Dunno what to say man. Mine is below.
2-3% at most over night.
And now it would appear that there is an issue with airplane mode.
I put the phone into Airplane mode at 2300 last night with 90% battery and did not pay attention to it. This morning I turned to phone on to find there was only 69% battery left, and WiFi was working. (see screen shot) WTF???? I have started using airplane mode to keep the battery drain to a minimum when the phone is not in use, and now it would appear that this doesn't work either.
I am REALLY getting frustrated with Android and Xiaomi as it seems that every time they do an update, something else goes bump! I have gone from totally happy with the AI when I first got it to being ready to write off Xiaomi as a company I would consider for purchase.

Play services also cause these type of sudden battery losses.

Thanks for the thoughts, but unless I totally misunderstand what airplane mode is, WiFi should not be active when airplane mode is invoked. You can see by the screen cap that airplane mode is on AND WiFi is active. This seems to be a one off as it has not happened again for the last two days. I turn airplane mode on to stop the overnight battery drain while the phone is doing nothing. I have location set to GPS Only. IIRC play services was just updated 3 days or so ago, so it should have the latest version. I will check it and see though. Again, thanks for the thoughts.

I can't logically understand why you would think it is the hardware causing the issue. If it was hardware, what you are seeing would be happening to every owner of the phone and clearly that is not happening. By saying it is the hardware when you have other software loaded is akin to saying your car's air conditioning doesn't work properly when you have all the windows wound down.
There is something loaded on your phone that is causing the systemUI to be working when you think nothing should be happening. The first thing I see on the screenshot on your phone is that in the top left of the screen you have two non standard icons. That tells me that you have a skin or non standard software constantly running.
The way to solve any issue like this is to go back to basics. I would get the fresh rom and do a Miflash whilst keeping your data. Make sure you do a backup first.
If that does not work, back up your data and do a clean install and check the phone's battery life. Do not load any non google software / app at this stage.
Then each day add one app and test for 24 hours. You will find this issue and the offending app or apps and I would be willing to bet you a few Singhas it will be an app you downloaded not the hardware causing this.

Actually, I think it is a combination of hardware/software, but that is just a WAG. Others have noted the exact same issue without running the same software. My bet would be on the RCS services stuff.

Those icons are my Email client and GSAM Battery Monitor (presently 0.1% and 0.8%) and are the only two constantly running programs other than the stock apps and Sophos (0.3%). Neither use much battery compared to the Android stuff. Presently Kernel is 41.6%, RCS/Phone is 30.3%. SystemUI is 3.3%, Play Services is 2.0% and Phone Services is 1.8%

Good advice. I will do this when I have a few days to play with it. In the interim, it's airplane mode every night. Thanks for the reply. If it turns out to be one of these apps, let me know where to send the Singhas.
Good luck with it. I hope you find the solution. It can be frustrating, but getting to the bottom of it will be worthwhile. I haven't used Sophos for a long time and even then it was for PC. I am not up with how Sophos AV is integrating into Android but that would be my first guess.
I have only had one issue with this phone after updating and it was that the OS was constantly asking for a password on unlock after using fingerprint not just on startup. A clean install solved it and I have been trouble free since with every update. With over 50 PCs in my office, I could only wish that I had so few issues with Windows updates as I do with Android.
For me, night light auto schedule not working properly.
I can't tether via wifi/bluetoth/usb
Made another post with the problem.

Just for grins and giggles, I uninstalled my email client, GSAM, and Sophos, the only programs that run constantly other than system and Line. I then turned my phone off and back on, forced stopped Line, charged it to 100% and set it down with the screen off. It did not move of get used for 8 hours, yet it still used 12% of the battery. (see screenshots) This is better than the 20% with those apps installed, but still not close to what I would consider normal. When I first got the phone, it easily lasted 2-3 days between charges, with 6-7 hours SoT. Overnight would use MAYBE 2% of the battery. Now if I want it to last 2 days I need to turn on airplane mode overnight and then I can make it through a day.
So I guess the next step is to do as you recommended and load up the fresh rom when I have time to mess with it. At least I am now pretty sure that those apps aren't the culprits causing the biggest part of the battery drain. I hate to do it, but I am seriously thinking of a factory reset and seeing if that clears the issue. Would that put me back to Nougat?

So those apps were causing 40% of of the 20% of the battery drain. That is a good start. I am confident there are software issues with your phone. I see you have some GPS app on your home screen, if that was running askew, it might be constantly pinging. That is just a guess.
In things like this, work methodically through it. But of cause a hard reset would be the best way to go. I see no reason why you wouldn't stay on your current version after a hard reset.
If you want to go make to version 7 you would need to use the MiFlash program and a downloaded standard fastboot rom. You may need to do something else to the phone to go back to 7, but I would not think so.
