Battery drain since latest update - solved!!!!! - Eee Pad Transformer General

Since the July 8.44.11 update my tablet in standby drains a good 3% or more per hour despite wifi off on screen off. This setting previously did not drain more than 1-2% overnight.
Nothing changed other than updating firmware.
Did some investigating to find the source of the drain.
See below as I think I found the source. Tablet was not getting into deep sleep.
OK I have solved this!!
I rooted the latest update and performed an experiment.
I used CPU spy to measure sleep.
With stock rooted the device was not going into deep sleep on 8.4.4.11
Then with titanium backup I froze the following to programs preventing them from running:
Mobile data and mobile network configuration.
Low and behold I now get deep sleep when testing this with CPU spy.
I suspect this wasnthe same source of battery drain in standby that occurred with the iconia tablet before a software update. Seems these programs are preventing deep sleep. Based on their description they seem designed for mms and sms.
Perhaps they were put there for the upcoming 3g enabled.models.

What do you have MobileDock Battery saving mode set to? Having this unchecked means your transformer is constantly spending power waiting for you to make a key stroke. If you have a newer keyboard or no keyboard you can check this and save that 2-3% per hour.
I do not see any additional power drain with the newer update.

I have observed increased battery usage in standby mode after the update.... an the average of 3% per hour. There has been no change in installed apps between the firmware update.
I rebooted the TF multiple times over the last few days without any improvement. Out of desperation, I plugged the TF to the recharge, and switch the tablet off. I let it charge up, and now the battery drain seemed to have reduced to pre-update rates. See screen capture of before, and after with the power-off-and-charge in the middle.
Observe also the CPU seems to be constantly awake even though the screen is off and in standby mode

2 observations I have made.
CPU spy shows I am not going into deep sleep
When I look at applications under the settings, under running services there is mobile data and mobile network configuration which to me seem more appropriate on a phone.
The iconia tab had issue with similar type process draining battery before an update. I wonder if the pre 8.4.4.11 update if those processes were running.

Experiencing the same, am on prime 1.6 (default kernel) and last night i removed charger when it was on 100%.
This morning battery was on 87%, this was after 6 hours. More then 2% per hour.
I have wifi setting on off when screens turns off.
When checking the applications in the battery info screen i saw "Maps" on top of the list. So when leaving to work i killed "Maps" hoping that it was the cause of the drain.
When returning home about 9 hours later battery was on 67%, so still about 2% per minute. That's even more then my SGS 2 with 3g on. So something is really wrong.

I saw an android bug listed, that after a reboot, the wifi sleep setting gets reset. Make sure that you select the wifi off when screen is off setting after rebooting.

I really want to help with this because there are a lot of people who are having these battery drain complaints and I just can't figure out the differences between my stock tablet and theirs. My tablet shows a very slow beautiful drain overnight last night.
My applications "All" shows the network and wireless applications also, however my running applications list is extremely small (Settings, The Weather Channel, ASUS Sync, com.asus.keyboard, Google Services, Music, Maps, MyNet, ASUS MyWater(asus live background)) so I can't say that network services are affecting my battery.

My TF has the same discharge profile as your device before the last 3.1x update. also, the CPU was never active in sleep mode. After the upgrade, the AWAKE bar is always active, and as you can see from my screenshot above, kills the battery during standby

Am trying this now, will report back. You did not charge it completely when turning it of as i understand from your capture.

Under google services, you might want to turn off picasa sync. I was told to do the same an I believed it has helped. Also try turning on airplane mode and see if it helps.
I have mostly unchecked all of the sync options which has helped in that my drain is like 2% overnight ~8hrs although I would like it to be even less .....

Inside that folder you will have checkboxes for everything Google that can be synced. IMO Calendar, Contacts, and GMail are all that is needed to keep you up to date. You can manually sync everything in the settings menu of the program you use less frequently.

Afraid u need to root.

Good find. Would help if you editted your original post with this solution. Hopefully this is fixed in 3.2.

So I guess this gives me another reason to root my tf101. Battery life is very important to me. This is the reason I got the tf101 with a dock so that I can get the full battery life of 16 hrs.

Thank you so much!
This is a great find. I just got my TF four days ago, so I haven't payed attention to battery usage, etc., but I performed these steps, so I hope to get maximum battery performance.
I also changed wireless settings to "turn off when screen is off".
This is why I love XDA.

Hmm, was looking around in Titanium - how do you freeze (prevent a prog from starting) an app?
Okay, found "deactivate" - this is the "freezer" ?

Battery drain when powered off w/o dock

I've noticed that when I attempt to power on my Transformer a couple days after powering down that the battery is completely drained as if the device was never shut down. The only way to power on is by plugging in to an outlet. I was under the impression the battery would last longer than a few days when powered down.
It definitley should, if I just put my tablet in sleep and leave it all day, it loses about 1% per day, so turned off I'd expect the same or better.

Wow, mine loses about 10-15% overnight. The same as the op... The batch number is B50*****
Mine too drains battery when in sleep mode. Also B5 build...hope an OTA update will fix it soon and that it is not a hardware problem.
Same here and I'm stock w/out root...
Sent from my Transformer TF101 using Tapatalk
Mine was in standby with airplane mode on (wifi off) - B3OK
100% battery was down to 64% by the morning. In 10 hours lost 36% battery
With all the talk about keyboard dock drain - I think this is more a important issue.
I have a B50 tablet, and mine only looses 1-2% per day if left in standby. This is in Airplane mode. Dunno what you guys are doing to loose half your charge over 24 hours.
Probably background apps. Some apps force load themselves (Like Thumbs keyboard and TapaTalk which wants to prevent standby on installation according to someone else on this forum).
I am also experiencing this issue. When I put the tablet on standby the battery continues to drain. When I when to sleep last night the battery was at 30%. When I turned it on this morning, it showed 4%!
This is unacceptable. The battery saving option is turned on. Is ASUS aware of this issue?
if you look at the battery info chart, does it show it becoming awake shortly after using it and staying awake for quite some time with the screen off?
Sent from my Transformer TF101 using XDA Premium App
B50 here. 0% battery drain. woke up and used it to check XDA for a little bit and went down to 98% but that's to be expected since most tablet/phones don't like to stay at 100% battery level to preserve it longer.
airplane mode while sleeping.

it would also be helpful for you guys to say what ROM / kernel you're using.. and if you're stock, say stock. hence why people on XDA have this stuff on their signatures
I am on stock. Could it be because I have some apps running that are causing this battery drain? Or is it the microSD card?

microSD wouldn't drain your battery. I would say check your battery usage but that's disabled on stock.
- Check your Google Accounts in Accounts & Sync. Is Picasa Web Gallery checked for syncing? I heard there was a bug about that and it consistently drained the battery even when you're not on Wi Fi.
- Any syncing apps, make the interval longer or make it a manual refresh if it's not important.
- There is a bug where the tablet may be trying to interact with Mobile Data. I'm not sure why but people on other Honeycomb tablets have reported the same thing. You can bypass this by activating Airplane mode. You can still use WiFi when it's in Airplane mode.
- I personally don't use any SetCPU profiles. They tend to do more harm than good. Just my opinion, it's up to you but if something's going wrong with your battery. Try disabling them and see if you notice a difference or not.
- My WiFi sleep policy is set to "when screen turns off." Even though I select this, my tablet still gives my notifications on emails and stuff. Seems to be working well for me.
- Don't use any task killers.
- If you use a kernel that supports undervolting. Play with the settings and undervolt. My kernel that I use doesn't support it but I still get good amounts of battery life.
- I don't overclock. This could drain your battery as well (unsure, but it probably does to a certain extent). At 1.0GHz my Transformer is fast and responsive so I don't OC anyway. I only OC for benchmarking for fun.
Many people have said to disable GPS. But in fact, GPS is on demand! Even though when it's enabled, GPS is only used when a app or the browser requests your location from GPS. I personally have it on, but it's up to you really.
There. I just compiled some battery tips. Hope they help.
A true way to find out if something is severely wrong is to put your tablet into Airplane mode while sleeping. When you wake up, check how much % you lost. If it's over 5-7%, I'd probably say something is wrong with your setup.
^OK thanks . I will give it a try when it is fully charged.

It's the serial number. Check the sticker on the dock for S/N or on the box that it came in.
After making the changes I described in my last post, I am now losing about 2% every 4 hrs. That is 0.5% every hour on standby. Much better than before but I believe others here have a much lower battery discharge rate.
I will continue to monitor the battery discharge rate under different scenarios.

Same problem, if left overnight looses around 30-40% of charge and looses 3-4% as soon as I disconnect charger. All sync is of, email check is manual. Juice defender is installed and on. So I have checked its logs and it says that almost every 10 minutes tablet uses WiFi connection. Went to Settings of WiFi connection and unchecked Notice about open Wifi spots and checked Always on when cgarger plugged in instead of "Always on". Will see how it works now.

Battery problems?

My new note's battery seem weird after I let it run to 1% and then charge up to 100%.
After that, it seems to lose battery very much faster.
Left overnight, it went from 79% to 49%!! a 30% drop!!
I checked Battery status report battery health is good and average 33-35 degrees temperature.
Bulk of battery usage is reported for Display (62%, "time on" of 1hr 30m) ...
Is this normal??
What can I do?
Thanks.
Maybe the battery needs some recalibration, run it down to 1% then charge the phone while its still off.
Here's the battery level profile...
Not sure what is keeping the phone awake even while screen-off??
Any help or advice to diagnose and resolve the battery issues appreciated.

Try a factory reset and then calibrate the battery.
Just woke up after the first night with the Note. I had 45% battery left when i went to bed, and now 9 hours later it's at 43%.

You diagnosed the problem correctly by identifying the device being awake while the screen is off. I suggest two tools to narrow it down:
1. Cpu Spy, Market, free, displays how much time the CPU spent in the different power states. During the night it should almost completely be in deep sleep.
2. BetterBatteryStats, Market, ~2.50$, allows to identify apps with wakelocks, apps which prevent the system to enter the deep sleep power state while the screen is off and the device basically is idleing. On CM Spareparts xan do that for free, for Samsung devices I first have to find a free alternative app that works...
No wipe needed (yet), no delete this or do that. First find the villain, then shoot em, not the other way round.
Sent from my GT-N7000
Installed BetterBatteryStats,
but there is lots of information, and I have little clue what these constitute or how to identify what apps cause the issues??
You could post screenshots of all the screens of betterbatterystats and we will try to help you.
Charge the phone to 100% and disconnect it right before you go to sleep, enter cpuspy and reset its counters. Then enter task manager and kill all the programs and clean the memory. Now go to sleep and when you wake up post screenshots of the built in battery stats, betterbatterystats and cpuspy.
Hi
I have a similar problem, my battery keeps draining entirely too much for what I think it should. Mine gets drained about 40% in about 10 hours of very light use.
BetterBatteryStats shows it is WiFi that has a humongous amount of wakelocks, but the thing here is I have WiFi disabled.
Image (BetterBatteryStats): http://antti.vahtera.org/images/SC20111221-020623.png
CPU Spy shows nothing that looks that weird to me, although I rather wonder why so little deep sleep and so much 200MHz, but that might be if deep sleep has a longer "counter" than it did on SGS/SGS2. If I use the phone to check time, or twitter from a widget couple of times per hour, does SGN enter deep sleep during those "breaks"?
Image (CPU Spy): http://antti.vahtera.org/images/SC20111221-020441.png
But, the one that caught my eye, was the stock Battery Info window. During the (almost) entire 10h time the phone was awake?! Why in the whole wide world? Does SGN really have some bug with WiFi keeping it awake even though it is disabled?
Image (Battery Info -window): http://antti.vahtera.org/images/SC20111221-020744.png
I really wanna get behind this. I love this phone, but this battery drainage begins to be a problem for me. I got about 2-5% drain per night with SGS2 and 10-15% per day on similar usage.

yeah, there's something seriously wrong with your phone. Are you rooted ? would you consider a full wipe and maybe a different ROM ?
Not rooted, not modified in any serious way either. (Using GO Launcher EX, not TouchWiz launcher, that's really the extend of modification on this phone.)
Android version is 2.3.6, Baseband N7000XXKK5, kernel 2.6.35.7-N7000XBKK4
This is what was shipped with the phone. It's unbranded and unlocked.
I haven't really done anything to it but installed apps from Android Market (and a couple with Samsung Apps).
EDIT: This is my day-to-day phone with all settings as I like them and all things set, so I would like if I wouldn't have to do a full wipe. But if nothing else helps, I guess I'll have to, in the end.
I hope someone will be able to help you cause I've never seen anything like that.

This might help...
I had the same problem. The first night my Note was dropping from 100% down to about 50% when I was asleep and the screen was off.
In the battery stats I could see that it was the Android core that used all this power.
So I tried a couple things to see if it helped:
1) I went to WiFi-settings and set it to turn off WiFi when screen off. This is a setting that is not on by default, you have to set it yourself.
2) I turned off AutoSync (Google account and so on)
Those to settings removed the overnight powerdrain problem. The next night it only went from 100% to about 98% when I slept
And since I am a serious betterysaver I also turned off autolight on screen, and set it to lowest light possible (still nice picture). I turned on the "Autoadjust screenpower), turned off all animations, turned off all kind of vibrations on the phone.
I left the"System powersetting" alone. It didnt save much power and it made the phone slower.
All in all, now my battery is great, I still have lot of juice left after a full day of using my Galaxy Note
I seem to have fixed my problem, without having to do a full wipe. I don't know which part it was that finally did it, but I'm glad it now behaves like I think it should. (about 2% battery drain in ~5h in pocket, one 1min phonecall and two or three times checking time from lockscreen.)
Anyway, I apparently ALSO had the infamous problem with Mediaserver eating humongous amounts of battery, so I'm not sure if that had anything to do with the WiFi keeping it awake or was just a separate problem.
Long story short, here's what I did:
a) installed JuiceDefender, had it manage Wifi
b) turned Wifi on, restart
c) turned Wifi off, restart
[d) installed nomedia manager and excluded most directories from mediascanner]
e) turned phone off, recharged to 100%.
Seems to be working now. No WiFi wakelocks, no mediaserver eating CPU, deep sleep ~70% of the time.

Unexplainable battery drain

For a month or more I'm facing totally unexplainable battery drain.
As seen on the screens below, the phone is awake, but it is not detected anywhere - not by android nor by GSam. In any case the battery draws faster.
I have one observation tho - this happens after I make phone calls. Not every time, but once per 2,3 days.
Any ideas?

You have this problem
http://forum.xda-developers.com/note-4/general/explanation-horrible-note-4-battery-t3004274
I'm pretty sure that I don't have this issue. Yes, the percentage in GSam maybe high, but I don't believe this reflects what is happening.
First of all - I don't have bad battery life. Usually my over night drain is less than 1%/1h.
Second - the issue appears sporadically.
Third - in the provided thread I don't see the issue appearing in stock battery monitor, while mine appear.
At last - my battery drains faster only while the issue is present and before I restart. After that it is back to normal ...
@Spo0f
Just some suggestions maybe you're using 3g I always have that turned off and switch it on when I use it my guess is that some apps are causing your drain after a call maybe like you said if you're not fimiliar with greenify I suggest you use it to stop all those apps and system apps also uninstall all those bloatware you don't need or at least freeze them if you don't mind lower the resolution to 1080p with nomone app use power save or disable dvfs and use an app to lower and raise the CPU to save juice when not needed....
Thanks for the suggestions, but as I said - this problem appear sporadically - home when using WiFi as well as outside when using 3G.
All of the rest is done - I'm no newby

Oh sorry mate well I don't use much 3g so I can't help you there but if you're having drainage when you're using WiFi in general then maybe you should reconsider investigating the post above with the link I don't have so much drainage on connectivity with 3g or WiFi....viewing the pics you uploaded it seems suspicious.... Maybe an app? I don't know...
Use wakelock detector

My overnight drain was also very low, but that was because the faulty device on the network was asleep at night too (my desktop).
If you're not rooted, use the PC version of Wakelock Detector at the end of your day and post screenshots of your highest drainers for the various categories. In my case, the device was being woken up by something on the network and it showed.
Bear in mind that actively downloading something in the time period will also raise wifi power used but more stats will help.
The fact that you're still experiencing a lot of drain even when outside suggests it might be a rogue app
One phone call today and after it the phone stayed awake.
Because I had issue with the PC WLD the screen shots are from 11 minutes after one of the disconnects. The device was awake all of them.

I also checked out my battery behaviour this night and was very disappointed. Although my phone was in flight mode and every peripherals and services shut down, today morning my phone was crying for energy. So I made a quick investigation in my power diagram and found out, that "Android OS" requested a wakelock during the whole power-on time. So I installed "CPU Spy" to check in which states the phone was really over the whole charging period. I couldn't believe my eyes. Although the kernel should do it's job good, cause most of the CPU times are in lower freqeuncy states, the deep sleep mode was never activated.
Therefore I installed an app called "Wakelock Detector" to check out which apps could cause that. I found out, that S Health had a big amount of wakelocks and also active-time, so the first thing was to disable S Health. After some minutes I checked back, but nevertheless still no deep sleep time in "CPU Spy".
So I searched around and found another one arguing about the wakelocks and that they could be the products of some programming issues concerning WiFi. The should be gone, after turning off WiFi and rebooting yout phone. And it seems that he was right. I waited some time and hooray, "CPU Spy" listed the phone state "Deep Sleep" the first time as an active state and also with the major active-time. So at least that was some step ahead. (I have to remark, that S Health was already unfrozen at this time, so S Health should not be responsible in any way.)
The next step was to reactivate WiFi, leave it on and set the phone on standby. After some time I checked back again the phone showed even more deep sleep time. So that was an improvement. I reactivated everything and waited some time... Deep Sleep all over the time. Can't figure out for now, if it was S Health, WiFi, or anything else that caused the wakelock for sure. At least the reboot helped. I'll check that out on a long-term test, maybe I get some further conclusions.

Phone Idle under Settings/Battery

What runs under "Phone Idle" on the V20. It's been the largest battery consumer for the last week of use that I've noticed. My wife's V20 is the same and I had my brother check his and his wife's V20.
I'm only asking because I'm not see great battery life like other have been reporting. I don't have live wallpaper, have only two widgets on the home screen. GPS is set to battery save, screen is set to auto but that doesn't even come close to chewing up the battery.
Sadly I feel like I'm still using my old 2.5 year G3 where it'll need a charge mid way through the day.

Really??
Pretty sad that needs to be done on a week old phone with minimal apps. I'm not even a heavy user.
I feel like I'm back on my old DroidX days where everything was a factory reset but never helped...

I agree with you. Although my phone is just beyond a week old and does have all my apps installed, a factory reset can't be the solution here. This is the typical "I don't know how to fix this" answer always given by manufacturers and carriers.

In the roughly 3 weeks I've had my V20 I've only seen this once where phone idle was higher than Screen. I started looking thru all running apps for 'keep awake' time being high and noticed Android OS had keep awake of over 2 hours when it's normally less than an hour after a full day use. I power cycled the phone and it stopped.
The weird thing was Android OS didn't show high battery usage even though something was triggering keep awake. Looks like the keep awake was causing phone idle to be high.
I'd look at everything in your battery usage to see if you have any high keep awake times.

Sorry did not mean to be short in my response. When you set up your phone did you restore it from another phone using the nfc bump thing? I did the same and my phone battery was the same way. Wouldn't last even half a day. After i factory reset and set everything up manually i get 18+ hrs with 7 hrs screen on time sometimes.
If this situation doesn't apply to you then maybe a reset won't help. But you have to understand your situation isn't normal.
Make sure Google now features are all turned off and not running in the background.

I'll have to go through the apps one by one like I did previously on my G3 and see. Now within the battery stats there is only a handful of apps like hangout, play music, chrome and camera. The rest is OS related so that's why I was curious what ran under Phone Idle.

No and sadly I was looking for that feature a week ago but couldn't find it so I had to individually install most of my apps I had on my previous phone...made for a long night along with the additional emails and configuration or icons and such.
I'll keep digging away at the phone...I really want to like this phone ?
Has there been a definitive resolution to "phone idle" battery drain? I just got a V20 2 weeks ago on sale for $360 and its a fantastic upgrade over the One+1 I've been rockin all these years, but I'm also suffering from mediocre life due to whatever phone idle is. Some forums (for other phones) say phone idle is related to your wireless signal. I'm still with the same carrier and frequenting the same locations and had no such battery drain with that old One+.
i finally discovered whats was goin on with me..
i had the same issue..
phone idle was topping my battery usage list
it turns google plays have this "locationmanager service " and locationwhatever" that kills your battery over wifi even with location button off
Go to locations/ 3 dots in top right corner/ turn off WiFi scan. See if that helps.
My phone has been suffering from poor battery life for quite some time now, here are the screenshots, Android OS has been this high on almost all battery cycles.
I disabled wifi scanning as suggested above and will watch the performance, does the community have any other inputs to fix this? View attachment 4212978View attachment 4212979

Phone idle is always the biggest battery draw on my phone too. I have minimal apps too. No Facebook or similar types of apps. I'm on a Verizon V20 stock with the latest security update. Is this normal V20 behavior to have phone idle consume more battery than everything else?
how about doze mode , isnt that meant to help with this sort of problem ? ( my phone is currently on a ship )
Any update. İ have the same problem

So what did you do?
Would also be grateful if anyone shared a solution.
I specifically have a SIM-unlocked Sprint model (LS997) which am using in Europe with another carrier.
Using it in LTE preferred mode drains about 10-15% overnight.
Using it in WCDMA preferred mode drains up to 5% per night (yes, wifi and cellular data OFF and many apps greenified) . So I'm really interested in how this can be fixed and achieve 0% battery drain across several hours.
Or maybe it's SIM-unlocked Sprint ROM related?? I can't root my phone since it has the Feb 2017 patch and is a ZV6.
I suspect rooting it and using another ROM would solve this + the annoying issue of not being able to send images via FB Messenger and Viber while on cellular data (I imagine the Sprint guys placed some kind of restriction to deny media transfer for these apps when using cellular data).
I have noticed this too.. wondered why "phone idle" takes most battery... any suggestions would be great!
I am also curious about the solution. Phone Idle is at top. Even without SIM card. 30% drains during a night (everything is disabled, but no airplane mode is on). I tried factory reset, reinstall older ROM, replace battery, use no app but still sucks.
hi
my v20 phone battery draining was about 1% per hour before (about 7% totally ) and recently increased to 2% during sleeping time overnight. (draining 15% overnight in sleeping state)
it seems that during day either performance off battery is decreased.(about 5h with wifi and screen on usage)
Fast charging while second screen is On , is slower than when it is off therefore when second screen is Off , fast charging goes better . exactly , first 30 mins fast charging makes about 40% battery charge(instead of 50%) and after 60 min leads to 85% and full charging taking place after about 100 min instead of 80 mins.
another important thing is that sometimes shades have been seen on the LCD that many users have complained about it.
phone information is :
Android security patch level: September 1, 2017
BASEBAND : MPSS.TH.2.0.1.c3-00045-M8996FAAAANAZM-1
KERNEL : 3.18.31
BUILD NUMBER : NRD90M
SOFTWARE VERSION : V10g-AME-XX
MODEL NUMBER : LG-H990ds
my actions are as follows :
phone is factory reseted. No third party apps is installed. [especially social media apps.]
battery calibration steps for not rooted phones is taken place.(turning off the phone and charging several times repeatedly).
testing battery drain in safe mode in done and didn't change results
turn off location services and location scanning for WiFi and Bluetooth scanning
turn off WiFi being On during screen is Off.
turn off auto sync, NFC, GPS etc.
not using auto brightness.
not using comfort view .
turn off location services and location scanning for WiFi and Bluetooth scanning
second screen is off during test overnight. (either with second screen is ON with faced down to lower brightness in other day test )
phone is in Air Plane Mode and all data services is off.
system apps like Google services and Play and Assistance is limited by permissions.
following are some advanced battery drain overnight figures of my phone for more analyzing.
any help with this issue is appreciated.

Battery Drain | Idle

My Essential PH 1 is draining a lot.
Phone idle is taking most power with approximately 17%. Screenshots attached.
Can you please advise if this is normal and ways to minimize battery drain ?

Are you showing off? because those are amazing numbers. You're on track for 35 hours! I get around 26. Your bigger killer is What's App, but that's expected for a Facebook app. 17% for idle means your phone is on and doing nothing 17% of the time.

Nope I am not showing off, I think i am having huge drains when I am asleep. Most of the time in that graph is idle time so i am thinking it should be better ?
Again I moved recently to droid from iOS so i am unsure of the droid power management baselines.

Cool. I didn't mean to seem mean, but those are good numbers. If your phone is on, and you have push notifications (pretty much every social media app, phone, sms, etc.) you're going to have drain. Even if the phone was off, the battery would drain somewhat. But you have What's App and other chat apps, so that'll use battery, even if your asleep, the phone isn't. It's the only way you would be able to receive calls, text, updates, etc.
That 17% looks steep, but it's all relative to a small screen. over the span of 20 hours and you still have almost 50% battery, especially with "free" apps that are basically advertising engines pushing ads at your every minute. Having Phone Idle at the top is not a bad thing, it just means you don't use your phone as much as you use What's App.
1% per hour is good, better than our S8 even
I had enabled "Cellular data always active" and it chewed through my battery life. I turned it off and can now last 1.5 days on a charge.
My phone is draining 12% overnight. And phone idle is top of the list. What does this phone idle do? There was a random night where the phone only dropped 1%. But most nights, it's draining around 10% with phone idle at the top.
Update: setting wifi to not stay on while phone is sleeping seems to fix the drain issue.

Does disabling it affect receiving messages that rely on mobile data such as WhatsApp?
Where is the "cellular data always active" setting? I don't see it. Have not updated to run Oreo.
My battery was dropping from 95% to 5% overnight. Did a factory reset which helped, but I'm still losing 17-20% overnight. Seems odd to me on a brand new phone, but I have never owned an Android before. I have blocked notifications and location services from nearly all of my apps. Any advice other than what has already been posted?
If your losing that much overnight it's probably a bad app.
I don't use it, but have read that the Facebook messenger is good for that. As in eating up a battery overnight.

I can promise you that that's not normal, especially for this phone. Overnight battery loss is minimal, 15 hours of idle with a 10% drain is what I'm getting. That's pretty amazing. I'd check your apps and ask the general android forums for advice. I also bet there is a rogue app draining you juice. chat and social media apps with all their pushed content and friend updates are huge battery killers.
Install accu battery ,charger to full last thing at night ,don't touch through night ,then see what's draining battery ,mine drains by about 2/3% through 8/9 hrs at night

It's under developer options settings. I have mine always active without draining my battery noticeable.
The social media apps such as snapchat, facebook, twitter, etc... are the ones draining your battery while your phone is idle so you need to disable their background data running.

The option to Cellular Data Always Active is on the Developer Hidden Menu. If you have it enabled you should be able to turn it off.
Thanks to all for the replies. I thought that restoring factory settings had helped somewhat, but it turns out not to have. Battery has just depleted from 100% to 67% in 3 hours while the phone has sat idle.
The only social media apps I have installed are FB and Whatapp. Notifications for both are turned off. Location services for all apps are also off. The only apps I have installed have been download from the Play Store and have run on my previous phones without causing any trouble. Those who replied all suspect a bad app, so I have installed ACCU Battery as suggested to see if I can nail it down.
Thanks again for the responses.
Try this for one night. Right before bed....
1. Turn OFF WiFi
2. Reboot phone
3. Leave WiFi off after reboot
There is a bug in Google Play Services that affects many people on many different phone types since the November updates.
When on wifi, in certain circumstances (many theories on what the actually trigger is) it will cause Google Play Services to run non stop on certain WiFi networks causing huge battery drain.
In this particular scenario, turning off Wifi does not stop the battery drain. The phone has to be reboot.
I don't know if that is what you are experiencing, as you didn't say if it was an app or system taking so much battery, but I thought I would mention it in case it helps.

Why don't you look in settings/battery and see what is using the highest percentage of the battery?
Have looked in Settings/Battery, but am not seeing anything there that diagnoses the problem to my understanding. Highest use shown is Chrome (4%), then Screen (4%) then Google Play services (3%). ACCU Battery app shows the same. Battery is still losing 10-12% of its charge per hour while the phone is idle.
Have sent a message to Essential support to ask if they know anything about a bug in Google Play services causing battery drain. They have so far only suggested rebooting to safe mode and doing the reset to factory settings. Hasn't helped.
Will try shutting wifi off, rebooting and leaving wifi off tonight as suggested. Not really sure where to go from there even if that does save the battery, as a phone that has its battery drained just by being on wifi is useless to me.
If turning off WiFi and rebooting helps reduce system cpu usage, it is a bug in the software and not the phone. I can reproduce that specific issue on my pixel 2 and Samsung Galaxy s8, too....
If the CPU usage isn't from system, though, or turning WiFi off and rebooting doesn't help then you obviously have a completely different issue and need to troubleshoot further.
Sent from my Pixel 2 using Tapatalk
Update:. Nothing Essential support has suggested has helped. Battery is draining to zero overnight while phone is idle both when connected to wifi and when not.
Upon learning that I had purchased the phone at a Telus store in Canada, Essential have said that they can't help me further and have referred me to the store for assistance. I'm disappointed in the lack of support from Essential.
