So somehow my phone did not like the Froyo update, would not boot after install or even a factory wipe.
So Verizon swapped it for a refurbished one, Ive had it for 5 days.
It had 2.2 installed when I got it. However the phone is almost useless for me now, It wont last a full day with nothing on, no GPS, no WiFi, no mobile data, no apps running, only turning it on once or twice during the day to check things and each time I do the battery draining like crazy!
I used to get 5 days out of my old phone, literally, because I am not a big user. I actually did play with the phone the day after I received it, to personalize it, and I drained 50% of the battery in an hour!
This is the same battery as in my phone, you dont get a new battery with the replacement.
I think its a hardware problem with the phone, but a guy at work says its just the 2.2 update, that it slams the battery.
Im going to take it back to Verizon tomorrow and see what they will do for me. If they wont fix this, I will simply revert back to my old flip phone since it lasts 5 days and cancel my data plan.
Keep on them to get that one replaced. Something in your hardware is definitely borked.
Even running WiFi hotspot, I don't see anywhere near that kind of drain (50%/hour). At the very worst, my idle drain was about 9%/hour.
This is not a good thing.

You need to make sure your old battery is calibrated to your new phone.
1 - install CWM recovery.
2 - tonight when you go to bed, power off your phone (power off is not screen off). Plug in your charger and charge overnight, USB charging prefered over wall power charging.
3 - in the morning when 100% charged battery is indicated, boot first into CWM recovery and wipe battery stats, after which boot back into Android then you can check for battery longevity again.

Wiping battery stats seems to be a placebo effect. For anyone with serious drain (several % per hour), wiping battery stats does nothing. Its a shame so many threads are corrupted with this misunderstanding when there are other very real sources of battery drain on froyo ROMS.

It's perfectly normal for some people that wiping batterystats.bin did nothing useful, it's also perfectly normal for others to loose 1/3 of battery capacity from being uncalibrated.
It's definitely perfectly normal for some to loose 10% per hour from being uncalibrated.
This kind of variance often confused people.
After doing some experiments, I think its Froyo.
The reason is I turned off mobile data and the battery only drained 2% in 3 hours. Then I recorded some vids of my daughter and played them back with her and over those 3 hours it only dropped 6%. Seems pretty reasonable. I know in my original post I said I had mobile data off, but I realized I actually hadnt, sorry for the confusion.
So I turned on WiFi and GPS overnight and it only dropped 4% overnight.
So something in Froyo is sucking down huge amounts of battery when mobile data is turned on.
Or its still possible its hardware related, that the data radio runs non stop when its turned on, just seems unlikely.
A guy at work suggested turning off data roaming and turning back on mobile data and seeing what it did.
I've had my phone draining at about 10% per hour before, never did figure out what caused the problem. But I flashed back to stock (following the instructions to get ED01 by flashing back to DL09 and then running the update.zips), and that seems to have fixed it. Since 2.2, I've stayed largely stock - stock kernel and just debloated the stock rom. So far, that's what I've found to give the best battery life for me - 48 hours on a charge on average.
Few things to do/keep in mind:
Clearing the battery stats might not solve the problem, but it can't hurt. Charge the phone to 100%, then turn it off but leave it on the charger. Once the powered off battery indicator on the screen shows 100%, boot into CWM and wipe battery stats. Take it off the charger, turn it on and use it normally until the battery gets down to 5% or below. Charge it back up and you're good to go.
Also, give it a few days/battery cycles to come up to full capacity. I seem to notice shorter battery life immediately after a wipe, but after a few days, it's back to the normal 2 days or so between charges.

Definitely seem to be software problem instead of hardware, I suggest leaving everything on -Wifi, GPS, bluetooth, etc... and disable all data sync only one at a time to check for power usage.

Load up Spare parts and see what it says in Battery History. Under 'Other Usage', it should show that running is less than 100% (depending on your usage patterns, this could read anywhere from 10-90%, but it should never show 100%). Do this after having been unplugged for a while.
If running shows 100%, you have a wake lock, which is forcing the phone to be awake 100% of the time, rather than sleeping and using much less power.
You can use dumpsys power from an su terminal or adb to look and see if you have any locks.
If no locks show up, and running still shows 100% (or even if it doesn't) with mobile data on, then there's definitely something wrong with the data radio, and you should have it swapped.
Don't accept any other answer from either phone CSR or in-store rep. No matter how they try and excuse it, constant 10%/hour and up to 50%/hour drain is completely abnormal.
Ok this is what spare parts says
Running 5.2%
Screen On 3.1%
Phone On 0.5%
Wifi On 77.2%
Wifi running 55.6%
Try this, it will tell you what it causing the drain.

Is that with Mobile Data on? Are you still seeing 10%+/hour drain with those stats?
If you're seeing that kind of running time (which is good), and you're still getting huge drain (which is bad), then your phone is broken and needs to be replaced.

Thats total since all time.
So I had the phone all weekend with wifi and mobile data on, then one day with wifi off, then one day with wifi on, mobile data off.
But the battery was consumed the most with everything on, but still very high with wifi off and mobile data on.
Unfortunately a refurbished phone must be returned within 14 days if there is a problem with it. The remaining time on the 1 year warranty is voided.
just use stock rom DI01package3.tar.md5 and battery is very good for me

According to the OP, you've had it for 5 days as of yesterday, which leaves you a full week+ to get it swapped again.

50% in an hour.. even if u use it the whole time is ridicuoulous.. prob a junk batt.. what are batt temps getting to??
There is a setting in the WiFi area to have the WIFI automatically turn off when the phones screen turns off, you may want to look into it

amazing performance great bat life runz like a dream!!
I just want to report that I've been having similar experiences, and in my case it seems associated with signal strength.
If I'm at home all day (where signal is good, and I'm on wi-fi), my battery life is pretty good. Not as good as it was on 2.1, but acceptable.
But if I'm out driving around, or in a place where the 3G signal is weaker (maybe 2 bars or less, but I haven't really verified that), my phone gets uncomfortably warm in my pocket, and battery usage becomes horrible. I've had the phone drain from full charge to 20% or so in less than two hours.
This problem never happened before I flashed the DL30 Froyo leak. Since then, it has happened on every Froyo ROM I've run, including official ED01 and the community ROM.
My Huawei has a horrible battery life. I'm using stock rom (rooted of course) and the battery drains really fast, like 5-10% an hour even in sleep mode. I have used a battery calibration app recommended by someone here in xda, but I don't think it made any difference. My last Android phone used around 1% an hour, even with data and sync on, but with pretty much the same settings, I can hardly make it through the day with my Huawei.
So, what to do? I don't need the battery to last for days, but having to recharge twice a day at worst is just too much.
My battery drops around 7-10% overnight.
Probably a defective cell?
mine after i installed custom rom (b160) and a battery calibartion in flight mode during my sleep after 7 hours that passed and woke up it was 1% dropped and now 7 almost hours afterwards in normal mode it has dropped 7% with very light use of course...
i want to say just that with gsm active it drained 5% more than in flight mode...
so something must be going wrong , like you don't have a good signal and it uses much power to keep your connection alive and have better signal....
i must say that i have a profile with setcpu when the screen is off with min 122 and max 460...
and just for the record i think that with custom rom also mine was dropping more...
i don't know why although...

Noticed this myself. i use spotify alot on the phone, walking, bicycling, at the gym. and it drains a whole lot of power even in offline mode. but if i set it in flight mode the phone last for hours and hours without even dropping 5-10% of power. but when gsm or data traffic is on the battery life just drains out so quickly! so it is definitly something serously wrong in this rom. Im hoping gingerbread is coming soon to this phone, so maybe all these small issues has been fixed.
I've found highly variable battery life. Sometimes it's awful, almost 50% overnight when it's sleeping on my nightstand, other times it's much better and only drops 7-10% under those conditions.
One thing is Google Maps, even when not in use it seems to suck battery like crazy if it's loaded (and it has a habit of getting loaded even when you don't run it or any apps that use it). There's a long thread on this in the Google support forums, but no sign of a fix from Google yet.
I've found doing a 'force stop' on Maps if it's running often helps, another thing is to reboot the phone after you charge it, that seems to fix it for several days sometimes, but then it starts sucking juice again for no apparent reason, so I tend to reboot it after each recharge. There can also be other apps that due to bugs can suck battery, for a while there app killer did this but the author put a fix out pretty quick and it shouldn't be an issue now.
Just noticed that there's an Android update from Huawei now available for download, maybe that'll fix some of the irritations and help with battery life; I'm off to install it!
where can you find that update? through phone's settings->check for update (in my case it says i got the latest version) or online?
My phone has been on for nearly 48 hours.. charging it right now. I played, connected to wifi, browsed the net, facebook, gmail etc.. and I really played hard on it for a few hours.
30mins ago it switched off, dead battery.. I'm quite pleased with the battery life

Exactly the same problem here. I formatted now both the internal and external SD card, let's see if that helps.
edit: No it doesn't. The problem seems to be that my phone doesn't sleep properly. I charged it to full, then turned the screen off for one hour. App called Spart Parts shows that since last unplugged, time spent without sleeping is 36m.
it took mine 2 weeks to get to the full battery life. now i get 36-48 hours from it.

After 5 weeks i get about 12hrs. No GPS, no 3G. About 10min ago i took the charging cable off. Now Battery History in Spare Parts show that "Since last unplugged" time spent without sleeping is 10m 33s (99.9998%), and time spent with screen on is 3m 23s.
im thinking of buying this phone is it available in India ? also can this device be rooted n what about the custom roms ? are they available as there is nthng on XDA :'( . And what about its battery life even being 1500mah is it so awful ?

Now after factory reset it seems that this is fixed. Over night with Wi-Fi and all sync's enabled, it took about 20% which is quite ok.

The problem is back... For some unknown reason the phone doesn't go to sleep and starts to use more battery.
Battery History:
Other usage, since last unplugged:
Running (100%)
Screen on (3,2%)
Partial wake usage, since last unplugged:
Android System: Total time: 13s
Dialer: Total time: 0s
Maps: Total time: 0s
It seems that reboot helps with this every time. After reboot, running-% is 32.9 when screen on is 6.5%. It would still be interesting and helpful to know what causes this.
its an android thing

That's not true. My battery history shows that correct(as far as I can perceive) running time.

I get most of the time also. But after charging, at one point (after some time) for some reason the time spent without sleeping goes to 99%. The problem is, that the partial wake usage doesn't show that something is wrong. Usually restart helps, but sometimes it can be already late, because 100% running has already taken quite much of the battery.
Also, when the time spent without sleeping is 99% or 100%, the CPU is still NOT in heavy use. So something just prevents the phone to go to sleep mode, and it seems that it is not the CPU that causes it.

I got it through the phone, it was the 2.2.1 B136SP02 update. Not online at Huawei website. It doesn't seem to have improved battery life alas (or the frequent WiFi dropouts I've had since new, particularly while downloading app updates). Main feature of the update is WiFi tethering/hotspot support, at last...
What seems to have worked for me after a couple of weeks++ of REALLY crappy battery life is a battery stats wipe.
FullCharge while the phone was off. First boot in recovery, battery wipe and then i just let it run close to dry before the first charge (almost 48 hours of medium use). Note here that i am now using the charger that came with the phone because i noticed that my generic usb one had an output of 0.7A instead of the full 1A of the factory charger.
Another point arose however. Does anyone else have stability issues when battery drops below 25%? I am talking about some serious crash/reboot/lag/noradio issues.
Some of you may have noticed that battery life on this phone can be both unbelievable and mediocre. I've been trying to figure out what can trigger and cause mediocre performance and I'm at a loss. The problem is, there doesn't appear to be a smoking gun. No obvious wake locks. No rogue Apps. I have Carrier IQ disabled by System Tuner. Google Now is off. What I'm running right now is pretty bare bones. And the kicker is my phone is sleeping, as can be seen in the shots below. The vast majority of the time my phone was off the charger it was in deep sleep mode.
I noticed my phone in excessive drain mode Saturday so I let it run over night and into the next day, so that BBS and GSam could pick up as much data as possible, including sitting idle overnight and very little use throughout yesterday.
Here are some shots to show the story. The graph, which is definitely steeper than when idle drain is normal, which resulted in idle drain of about 6% per hour. Also as can be seen in these shots, there is not a wakelock problem. Deep sleep shows as 12 hours 38 minutes, Awake time of 1 hour 8 minutes, and screen on time of 1 hour. So, my phone was only "awake" for 8 minutes when the screen was off out of almost 14 hours according to BBS.
I did notice and oddity here though. BBS listed the unplugged status as 13 hours 47 minutes, while the phone's battery meter listed it at 12 hours 13 minutes.
Attached are the shots I took at 19%, as well as a final battery meter shot after charging the phone to full while powered off and restarting, where it's been purring like a kitten in deep sleep.
Part of me is beginning to believe there is a bug with the battery gauge. What do you guys think is going on?
Try clearing data for google play services,google services framework and playsore than reboot and check if things changed.
And i would recommend uninstall the updates related to those apps and let them update itself again.

Done. Although I won't know if any attempts to resolve the issue have worked until the idle drain triggers again (or doesn't).
Thanks for the advice.
Well unfortunately that didn't solve the issue. The heavy deep sleep drain again triggered after a bit over one full day. I charged to full last night and let sit over night where it drained 6% per hour with no obvious culprit. Anyone else have any suggestions?
It seem that your signal is week, did you get stable signal and have you tried airplane mode, to find out how much battery drain in this mode?
Also, did you disable LG MLT? This is a massive app from LG, can consumed about 150 MB RAM.
This might sound boneheaded, but what about just resetting the phone. Maybe some system app is causing some type of memory leak and thus draining your battery. Also disable wifi when you're not using it.
I don't think it's signal related. I get an excellent signal at work and the idle drain still occurs. Also, it happens whether wifi is on or not. I have not disabled MLT, as I'm not concerned about RAM, just running processes. Rebooting the phone eliminates the issue, so something is obviously getting hung. The really odd thing is I was draining 6%/hr overnight, all while the phone was in deep sleep, yet my top battery consuming category was the screen at 35%, with just 1 hour of screen on time of 10 hours off the charger. If something was cranking in Android System that caused 40% drain overnight I would have expected Android System to be higher. It doesn't make any sense.
I may just have to factory reset.
My battery's been great until couple of days ago when I turned on GPS and Voice Notification (for speaking out names when phone call/message comes in). After I noticed the abnormal battery drain, I turned off those two options, because that's the only thing I did differently before noticing the drain. However, that didn't help... yet. I needed to do a reboot and battery's been fine again. Not sure if those two were the actual culprit, or just coincidence.
Have you changed any settings right before you noticed the drain? Just a thought.
had the same issue., wakelock detector, BBS, GSAM nothing could show what was eating the battery. i use mobile browsing a lot and almost 8/10 times this battery drain was happening with chrome , chrome beta and firefox browsers.
Only thing thats helping me is the Greenify app . Greenified the chrome and firefox and almost all the cloud apps and the battery is now much much better.
still ...IT IS AN PROBLEM to be found..
To provide a bit more info on this, attached is a pic of my reboot a couple hours ago (marked by the thin white vertical line). The change in the slope of the drainage line is drastic. Also, notice the small hump after the reboot? The line actually increased a bit, fell, then flat lined. More and more I'm beginning to suspect the battery gauge, but I just don't know.

I have the same situation after charging. Even in"deep sleep" it would chew through the battery. Now I just reboot the phone after charging and it plays nice. The gerbil on the wheel seems to take a break and rest.
To all who have excessive battery drain, did you charge your phone while it is on or off?
Some where in this forum (if not mistaken), I read that there is a bug while charging G2 when it is on. You should reboot your phone after it is fully charged otherwise you will experience excessive battery drain.
Mine always charged it while it is off and never had problem with battery life.
i got the same issue which is very annoying, have over 85% deep sleep, no wake lock, battery draining like crazy, and it happens randomly. I wonder if factory rest fixes the problem, or hardware issue
i have done a bit testing for this random drain,
with mobile signal on ==> huge drain
without mobile signal on and only phone signal ==> huge drain
airplane mode ==> no drain
so i believe it is a bug within the phone software, actually sometimes the random drain started after a phone call
I've been getting the drain too in the past few days. Last time i could fix it by factory resetting, but obviously I don't feel like doing that once per month. What I do know is that flashing another stock ROM (kdz) without factory resetting doesn't fix it. However last night I figured i'd try disabling WiFi (kept it on during the night until now) and I only drained 1% in 5 hours, down from 3% per hour. Perhaps this bug is related to WiFi.
Have you disabled LG MLT? It acts like CIQ for internal LG purposes. I have personally seen it cause mass wakelock in unexplained situations. If I leave everything on overnight under 95% battery, I will get around a 3% drain in about 7 hours. Pretty normal. The first 5% on these batteries seem magical. At 100%, with everything on, I wake to 100%.
Yup, frozen in TiBu. Will be factory resetting however when I get home as GSAM grabbed my attention. Never were system things so high up the list when i had no drain.

To all who have excessive battery drain, did you charge your phone while it is on or off?
Some where in this forum (if not mistaken), I read that there is a bug while charging G2 when it is on. You should reboot your phone after it is fully charged otherwise you will experience excessive battery drain.
Mine always charged it while it is off and never had problem with battery life.

I been struggling with this since I got the phone (almost a month now). I've done all the usual:
Removing bloat
Disabled CIQ
Disabled Google Now, Location, GPS
and I have the same apps as my Nexus 5
Just last night I realized that this battery drain only happens after taking it off the charger. This got me to add the word "charging" in my search and I found this thread.
Is this hardware related, or would a custom ROM resolve this? I have the AT&T version.
Ok and which stock rom does not do that?

Probably this is a software issue. Never heard this problem on latest firmware or custom ROM.

Guys could you write which stock rom does this wakelocks for you so we could eliminate corrupt firmwares?
For example I experience these wakelocks on latest F international version.
I've got the 16gb nexus 7 (non 3g).
I've had it for less then a year and the battery life had been great. But starting over the last few days the battery is horrible. After a full charge over night my battery was down to 50% today. And that's with hardly any use. I used it for maybe an hour total and at least half of that time was just reading reddit.
I haven't changed any settings recently. This is all stock, no mods, not even rooted.
The battery usage right new says it's been 13 hours, and it's down to 48% and Android os accounts for 27% Followed by screen at 18% and WiFi at 9%. Those are the top 3 showing for battery usage.
Any suggestions as to what's going wrong it how to diagnose be fix it?
Thanks
Either your battery is bad or you have a stray process running somewhere.You might want to factory reset it, possibly even reflash your image.

Would the battery go bad that fast though? In my experience batteries usually gradually get worse. This went from losing a few percent of power to losing half power in the span of a day.
I might try the factory reset - just have to make sure everything is backed up. This tablet isn't rooted so i dont have titanium backup on it.

Doubtful it's the battery... my money is on a rogue app!!!
Hi, merkk...
It's possible, that as the previous poster suggests, some rogue app is 'eating' your battery.
The biggest consumer of power is the screen, so ensure you haven't got it set it maximum brightness... and ensure auto-brightness is enabled in settings.
Another thing you can check, is your WiFi setting... on my Nexus 7, I have 'Keep WiFi on during Sleep' set to 'Never'... it's not a setting that is easily found - it's buried in SETTINGS>>Wi-Fi>>overflow MENU (three dots, top right hand corner)>>ADVANCED>>Keep WiFi on during Sleep.
It also might be worth checking if the SYNCING of your respective accounts (Google, Twitter, etc.), haven't been inadvertently changed. Particularly the SYNCING of your Google account... which by default, SYNCs a lot of stuff and frequently. This will keep WiFi awake, and may cause battery drain. Go to SETTINGS>>ACCOUNTS>>GOOGLE and disable what you don't need to be SYNCed.
-----------------------------------------------------------------------------
It's unfortunate that your Nexus 7 isn't rooted, because there are a couple of excellent diagnostic apps available (GSam Battery Monitor and BetterBatteryStats) which provide more granular and finely detailed battery info/history than the standard Android battery info screen... and are useful for tracking down problematic apps that might be keeping the device unnecessarily awake ('wakelocks', etc.).
However, due to changes in Android 4.4 (KitKat), these apps now require root access to read and report battery stats info.
If your Nexus 7 is running any version of Android BEFORE 4.4 KitKat (and some haven't updated yet), then you don't need root to run these diagnostic apps.
-----------------------------------------------------------------------------
It's sometimes the case, with Android, that there will be occasional peculiarities with battery performance... and in my experience, it's almost always the case, it's due to something the user did... some app or widget installed. I'm currently experiencing similar battery issues on my Samsung Galaxy S3, but having run GSam for a couple of days, I think I have the culprit identified. If I can't eliminate the problem, I'll uninstall the app.
-----------------------------------------------------------------------------
Hope my ruminations are of some use.
Rgrds,
Ged.
Gedblake, thanks for the suggestions. For whatever reason, today it seems to be back to normal. The only thing i did last night was drain the batter to around 10%, turn it off, and let it charge while turned off.
Turned it back on today,used it for about 15 minutes or so playing a game. And now just about 5 hours after turning it on, it's down to 92% which is what I'd normally expect.
I'll try some of your suggestions if the problem re-occurs.
I noticed that my N7 (2012) has been draining quite a bit lately. Watching the battery stats, it seems Google Wallet was eating up some major battery. It was 2nd at 29% with the screen number 1 at 38%.
Not sure what the heck Google Wallet was doing, but I killed it and things seem to have stabilized.
battery drain after update?
For years I've had the same routine. I use my Nexus 7 all day for work, mostly notes. In between I play, (youtube, E-reader, etc). Every night I plug it in to charge and in the morning it's fully charged and ready to go. On Tues, I received the OTA update for 4.4.4 I noticed this morning that after a full night's charge, the battery only reports 50% charge. Is this the beginning of the end? What steps should I take from here? I recently bricked by GS3 so I depend on this thing now more then ever, any help would be sooooo appreciated.

I'd just restart it and let it charge again. I've updated mine a while ago and haven't had any issues.

I'm on a custom 4.4.2 ROM and I have had intermittent draining behavior as well.
Sync is off, location services off, I turn off wifi manually, and I always clear recents before I have my tablet sleep. I have greenify installed. I'm using better battery stats.
My issue seems to be similar, but I am also having battery percentages jump around.
Earlier today it went from 26% to 43% in the middle of me using it. Without charging. It frequently does this, both lesser and greater values reported. I've had my tablet shut down in the 30% range. I've had it shut itself off on 4%. I've had it drain all the way to 0% and then some before shutting down. I've had it turn itself off and when I power it back on the tablet is thinking it is at 25% or more.
I haven't been getting much more than an hour of screen time with my tablet lately. Clean fresh install of my ROM.
But I've never, until the last couple of days, had it go from a small percent to a large percent active during use. I took screenshots. I even started a thread to talk about it but nobody has responded yet.
Has anyone else ran into this behavior? Is it a sign of a soon to be dead battery?
mine got almost 30% drained on idle, airplane mode, screen off for 3 hours (tested on stock rom 4.4.3. GApps + Swiftkey + BBM + Facebook only)
my nexus 7 never lasted a day, only half a day max.
trying GSam app, hope it helps in knowing what's eating up batteries.
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 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.
