Massive battery drain

Hey guys. Recently my battery has been dying at an alarming rate. According to BBS it's from a process called diagnostics.client.Wakelock, does anyone have an idea what could be causing this?
I started noticing the drain after setting up my Galaxy Gear, don't know if that may have something to do with it.
Thanks!

Same issue here. Not sure what it is. Google didn't help much either (besides finding this post)

I am seeing the same wakelock keeping my device awake and hence draining the battery while in standby. Found nothing else on the web other than this forum

Why don't you ask in the BBS thread, i think you'll get more responses there.

Thanks! I'll give that a shot.

I am facing a huge battery drain as well after the recent update was pushed. I don't have the "diagnostics.client.Wakelock" in BBS but Samsung Push Service was hogging a lot so I turned that off. It was 80% at 11PM and today morning it was down to 59% .. that's 21% in standby mode. Is it not going into sleep mode or is something else causing this? I have almost everything turned off. Any ideas guys? Thank you.

MJ7? (not sure why but like other people remarked - the battery life looks to have somewhat declined - 30-60% less?)

Yes MJ7. I hope this is a bug that can get fixed sooner than later. It's horrible. I just got 1h 37mins of screen time and now I am down to 12%. Just a few calls and some Instagram. Nothing else. Would removing the battery for a while or something help? I haven't installed any app since updating to MJ7 (2 days ago).

I've had this issue with MI7 and MJ7 so the update is not the problem. My guess is me freezing most of the samsung bloat on the phone through Titanium is causing this. Maybe there's a process trying to find something thay I froze?

I fixed it by charging my battery up to 90% then removed the battery and kept it aside for a while ~10 mins and then plugged it back in and charged it to 100%. Now it seems to be normal again. No drain last night. Moved only 1% from 12AM to 9PM. Cheers!

I have the same issue with MJ7 firmware; the phone sometimes doesn't get into deep sleep while the screen is off.
A possible cause of the issue: switch off wifi when data are off.
So now I switch data on before turning wifi off.

Anyone ever find a solution to this? It's killing me.

Same here, my battery declines almos 1% every 5 minutes just texting via Whatsapp and I know Whatsapp is not the guilty. Using Wakelock monitor shows 30% Android System usage with a lot of entries in Gpslocationprovider (even with GPS off and everything on Location settings off), SyncloopWakelock and AlarmManager... MJ7 here too... My Note2 wasn't like this... I finished the day with 5% of baterry after heavy use from 8am til 10pm (including 45' watching videos)... With my Note3 at mid-day I have my battery death!! I can't believe it! and I don't know what is happening (I only have 4 days with my new Note 3) and I have tried almost everything (deactivating) except wipe data/factory reset (I've tried soft reset and nothing)

Anyone ever find a solution to this wakelock?

anyone find a solution?

Delete Google search from system apps and deleted Google play services. Redownload both from play store. Seems to help.

I noted that my GN3 would have great and then poor battery drainage. It seemed to happen right after my first long call of the day. I noted in my wakelock app that diagnostics.client.wakelock was using a lot of time.
I decided to take more drastic action by doing a factory reset and restoring apps one by one. I first used Kingo Root to root my GN3. I had to uninstall Kies and the Samsung driver to get the rooting to work.
Then I backed up with Helium and Titanium backup.
After a factory reset, my battery usage was about 0.2 percent per hour. I use only data and no wifi.
I have now restored most of my apps and still have 0.3 percent per hour usage. I have not updated any Samsung or ATT apps.except for ATT code scanner. i have not "used" any of the google apps except for gmail, search, google+ (signed out). Google music is turned off.
Diagnostics.client.wakelock still shows up but with low time now.
After twelve hours, the GN3 is at 96 percent including a two minute phone call and email updates.
------
After a long phone call, I once again saw my battery usage increase and stay up after the phone call.
-----
I re-started with a factory reset and only restored the minimum apps that I use to browse, email, text, phone, and backup.
So far it is performing well in battery usage.
I will be adding more apps until I find the one that breaks the good performance.
-----
So far I have been able to make it through 24 hours using only TEN percent battery usage. I have added TextPlus, BofA, drippler, Helium, Titanium Backup Pro, CPU Spy Plus, Wakelock Detector, System Tuner Pro, Battery Monitor Pro, AutoBluetooth, Maps, Youtube, YP, Total Commander, Visual Voicemail, Quick Boot, Root Checker, Turn Off Screen. Everything else is stock without updating AT&T apps or Samsung apps.
I am seeing an idle usage of less than 0.3% and that is with two widgets for Battery Monitor and System Tuner. They and Textplus use up the most power. I also talked on the phone via bluetooth for about 30 minutes.
I still get the diagnostic.client.wakelog but only getting about 5 percent awake time.
-----
I did another factory reset. This time I did not allow any app updates.
I installed Titanium Backup, CPU Spy Plus, Wakelock Detector, Battery Monitor Widget Pro.
I have not seen a diagnostic.client.wakelock at all after one hour of use.
-----
I added TextPlus, System Tuner Pro. I put the widgets to System Tuner pro and Battery Monitor on the home screen.
I have not updated any apps since the reset.
I have counted about 7 diagnostic.client.wakelocks for a total of 4 seconds of wake time. My wake time percentage since yeaterday is around 1 percent.
I plan to update apps one at a time to see which one kills the battery usage with wake locks.

I just added AT&T Visual Voicemail, PayPal, BofA, and Evernote to my GN3.
The diagnostics.client.wakelock started climbing and keeping my phone from sleeping.
Uninstalling the four apps did not help.
I think that the problem is with the Visual Voicemail.
----
Factory reset my phone and am back to 1 percent wake state and very low battery drain.
----
The cause of the bad wakelock was due to restoring APP+DATA in Titanium Backup. I did that to save setup steps.
I had restored BofA and Shazam with data and the wakelocks started up.
After I factory reset again, I installed apps the normal way and have been seeing a 0.3 percent use per hour.

Samsung's own software is most garbage in my opinion.
If you use ChatOn and Samsung Hub, etc, disabling this may have an impact.
Here's how I've solved the problem with this pig of an app.
1) go to application manager under settings.
2) go to the "ALL" tab
3) find that "samsung push service"
4) uninstall - this will only uninstall the updates. Once all the very useful updates are gone, the option changes to disable.
5) disable and good riddance.
On a side note, search for this on the playstore. the reviews are hilarious.
c.

Nothing I had tried up to today has fixed my battery drain and diagnostics.client.wakelock issue.
However, today, I got a software update OTA (nb4) on my phone and it appears the problem is fixed.

Lollipop battery drain

I got the German 5.0.1
IS it only me or is it general with the battery drain?
Even in Flight Mode, I am losing the battery in a couple of hours

Hello everyone, two days ago i downgrade to kitkat, I decide to re-put Lollipop because I'm documenting on various forums Italian and foreign, and this drain the battery does not have all .... well for my case I installed the GSAM Battery Monitor from Play Store that seems to work well with Lollipop. I left the phone idle and discovered that the deep sleep has never been reached. The phone was always active, even when locked.
GSAM has reported that the app "Unified Daemon (EUR)" was among the top three applications that consume battery.
According to various forums is a preloaded application from Samsung that unifies information like weather across other applications preloaded. I really do not know what good has this application.
I tried to turn it off, and in fact the phone goes into deep sleep with consequent consumption "standard" like KitKat.
The downside of disabling this app is that you lose the weather from the lock screen and through the window of the cover S-view, while the widget on the home seems to work perfectly.
Obviously there is to say that others should do the same test and see if this app will appear among the first applications to battery consumption.
A greeting

disable Facebook app (use web version) and turn off wifi when not being used. My battery usage has transformed! See other thread....70% after 10 hours. 56% after 13 hrs! Lollipop is buggy. Manage wifi manually and you're battery will be awesome.

^^^^this^^^^ . Me too. Disabled damn Facebook and it a few Google apps and I'm back to normal. The main culprit is the stupid Facebook. To make easy access of it from Web just make a shortcut on your desktop.

I will leave wifi on today regardless of whether or not it is connected and see if things get warm / battery usage ramps up. If it doesn't it might indicate an issue with FB alone or at least prove whether or not wifi is stopping the phone from going into deep sleep after a period of non use. Yesterday having left FB and wifi off, resulted in 40% battery remaining after 16 hrs usage. It never got hot once. This is my yard stick.
Lots of users are having issues with the latest update to facebook - just look at the comments on the play store!
Anyone else been having high battery usage but are not users of FB app on lollipop?

@gasland Here is what i did.
I uninstalled
Facebook, Facebook pages, Facebook messenger and com.facebok."something"....
I removed everything that had the name "facebook" and rebooted my device.
Battery has been okay since then.
Ps: I also froze "unified demon" as I don't use either of the weather services or finances or all that crap.

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.

Pretty sad that needs to be done on a week old phone with minimal apps. I'm not even a heavy user.

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.

Trying to track down cause of recent battery drain issue.

Hello all,
So I know there's various discussions all over the web about the Galaxy s10 and battery issues on both Snapdragon and Exynos variants. It seems people are experiencing a wide margin of difference in avg battery life..
So here's my situation. My wife and I both have S10+'s through AT&T. We got them the first week they came out. I looked though the forums and performed several battery optimization tweaks on both phones and since then the battery life has been really impressive... No complaints really. Until this last week.
We both recieved the March security patch and fingerprint scanner fix about a week ago. My wife's phone seems unchanged by this. Everything working as expected. My phone however has been draining battery MUCH faster both in SOT and standby time. I'm losing 2-3x more battery % overnight. In the last 20 mins of just reading through threads on the XDA forum app, I've lost about 10% battery. I'm sitting in the dark with my screen brightness very low too. (down another 5% since I started typing this!)
My wife and I have very similar phone habits. Since both our phones are optimized identically, and we used most of the same apps a play the same games, I started looking through everything different I've done in my phone since this problem started. I installed Adhell3, which seems to be setup properly and working. Mike B. from Adhell's Discord assured me that Adhell shouldn't be draining my battery. I'm mostly using it just to remove a bunch of basic bloatware and block some ads.
The update seems to have worked fine otherwise. My FP scanner is much better now, but something is definitely wrong. I've tried wiping the partition cache afterwards. I've tracked down others experiencing issues after this particular update, but cant seem to find a way to fix this problem yet. I saw something about Deep Sleep problems after the update when someone uses a VOIP service like Skype or WhatsApp, but I dont use anything like that. I can't even find a good tool to use to see more information about my battery usage, as the built-in battery monitor lacks a good deal of information. CPUspy doesn't work on my version.
If anyone has any ideas of what could be the culprit, what else I could try, or what tools I could use to try and track down what exactly is causing this sudden increase in drain, I'd really appreciate it.

Which update do you have ASBA or ASCA? This is rather weird, Battery drain can also come from restoring from backups. I lose 2% every night and my phone is on airplane mode, not connected to anything except location. I do not have adhell, and last time I tested before the fingerprint update I had 10h SoT on wifi purely. When I got the new fingerprint update I checked if the phone went to deep sleep and it does, so I really do not know what might be your issue. I have an exynos variant btw. Also I charge my phone constantly from 80 I let it drop to 40 and charge it back, I do not use fast charging options. Since unplugging my phone now on LTE fully I have lost 1% in 30 min, I have my fitbit always connected, location on, max resolution, I have a semi black wallpaper and brightness around 40-50%.
I will see today how much SoT I can get from 80% part wifi, part LTE, I will update.

clear cache helped a lot of people

Update 1

Reset all phone settings to factory. Don't do full factory reset, just all the settings, fixed my post update battery drain issues

Update 2

Hrrm. It seems I don't have ASBA or ASCA, I have ASD3. The March update.

I'm really hoping I don't end up having to factory reset and manually install everything... Because I did do a restore from backup with AT&T Transfer, because it seemed really convenient and time saving. I had no idea that so many people have had issues with restoring from various back up services (AT&T, Samsung, Google etc.)
I did the same restore from backup on my wife's S10+ too and she's had no problems. Her battery life is phenomenal. My battery issues only started after this last update.

Well that seems rather strange to be honest, you can eliminate possibilities by just testing and see what works. Last possibility can be that factory resetting and installing all new, but then again, it could be that it solves your issues or not. You should be having rather horizontal lines to prove your phone is truly going into deep sleep in my opinion, but also you can check with CPU Spy

Sorry it will be this pic

Try to log too safe mode and check the battery drain
If stopped then it was from an application that have a problem
If not I think it might be a system app or something

So. I'm starting to think that some of my problem has to do with wakelocks. Unfortunately I have limited access to wakelocks statistics since my phone is unrooted. However. Last night I fully charged my phone right before bed and then took it off the charger to see how much it would lose overnight. It dropped a whopping 10% vs the 1-2% it used to.
I looked through some of the battery info and noticed several apps running in the background for very long periods of time since last night. Chrome(2hrs) , Discord(2hrs), Google Play Services(a whopping 13hrs 30mins running in background) and Google Play store (5hrs)
Somehow Discord was responsible for draining 7.6% battery in that time!
So, could this be a wakelock issue causing my phone to lose so much battery overnight? I know that's only half the problem, because I'm also experiencing higher drain than usual while using certain apps too. But I'm trying to figure out one thing at time.

You can look at this thread and see if you can install the app without being root or not

You just need to tweak your settings more, put which apps do not run on the background or go to sleep, how many days you need to wait to put unused apps to sleep. Is all tweaking the settings.

Then I don't what you can do, either do a factory reset and so not restore anything from backups and see if that works. I usually set my phone that way, clean no restoration from any backup all apps are installed manually, and I do not even use adhell to disable most of Samsung crap apps and services.
