Hi there,
i have a problem with my milestone and cyanogenmod 6.3.2 (and the same in earlier versions of this rom).
After flashing the rom, deep sleep works for a few hours, and after that, without doing anything special, my phone doesnt go to deep sleep at all.
When i take a look at the battery stats, there is "running" with 100 percent, and partial wake usage is fully accounted to "android system".
I tried to restart after charging the phone, but it doesnt help. With stock rom, i have normal deep sleep accounting for about 80 percent of usage time.
Anyone has an idea how to fix it?

What app you used to see this "battery stats"? If you have a SS or a LOG it would help us to help you.
it's the built-in battery history that can be accessed via spare-parts. i dont know if and where this is logged somewhere as a file.

After updating to 6.3.3 I figured out that deepsleep worked until the first reboot. I also noticed that, after restoring 6.3.2 with nandroid, deepsleep also worked before I rebooted for the first time.
Anyone has the same problem or any suggestions (except 'dont ever reboot')?
I had the same issue on 6.3.2. After upgrading to 6.3.3 and playing with wifi settings the deep sleep started to work. One more thing I did was going into sleep mode with CMMod extended button (Zzz on notification bar)

thanks for your response. can you tell me what exactly you did with wifi settings? i also tried going to sleep mode with Zzz button in notification bar, but it doesnt work (screen turns black, but cpu runs at 250 mhz, and no deep sleep).
Hello,
since i flahsed this kernel, the phone works, but it wakes up from sleep mode all the time, causing the battery to discharge very fast. Is there a solution for this?

Imho an even better explanation on the whole wakelock issue and how to solve (some of) them:

We need more information what's causing the wakelocks, before we can (try to) help.
→ Install Better Battery Stats and let it run a few hours.
the solution was disabling home button wake up screen in Android cyanogen version. Thx for Reading.
I noticed my Samsung S10 T-Mobile Snapdragon would drain about 15-20% overnight while asleep (6-8 hours) since last week or so. The drain during the day is also significantly worse, but it's easier to compare the numbers when on idle. The first weeks that I had the phone, I was losing less than 5% overnight (6-8 hours). I am not sure if this was caused by the security updates, carrier updates, or a rogue application. I made no changes to the phone settings that I can recall. My phone was connected to WIFI overnight, with cellular, cellular data, and Bluetooth on. Prior to going to bed I would charge the phone to about 80% and unplug it.
I installed AccuBattery after reading some forums and it showed that my battery drain overnight was about 2-3% PER hour. AccuBattery also indicated that my phone was in deep sleep +85% of the time. The breakdown per application does not total the 15-20% so there's something else draining the battery. Eventually, I uninstalled AccuBattery to see if it was contributing to the drain, and it made no difference.
Below are most of the things that I have tried and tested overnight while I slept (6-8 hours), all of them have been UNSUCCESSFUL at solving the battery drain. I might have forgotten some other settings that I have changed. Keep in mind that this took me over a week of playing around with these settings, and checking the battery right before and after I went to sleep.
Restarted phone (There's always someone who would suggest this if not written down)
Cleared Google Services, Google, and other Apps Cache and Data
Cleared Cache Memory (Through recovery menu - Tried this about 5 times at this point)
Reset the big 3 (Reset settings, Reset network settings, Reset accessibility settings)
Enabled Airplane Mode (Cellular, WiFi, Bluetooth Off)
Disabled Location
Disabled Sync
Disabled Always on Display
Disabled ALL Motions and Gestures (e.g. Lift to Wake, Double tap to wake, Smart Stay, etc.)
Disabled Video enhancer
Disabled Game Launcher
Disabled Bixby Routines
Disabled Nearby Device Scanning
Disabled WiFi Scanning and Bluetooth Scanning (Improve Accuracy)
Disabled Show icon when screen is off (under fingerprints - from Samsung Forums)
Disabled certain Apps (AR Emoji, ARCore, Briefing, Chrome, Game Launcher, Google, Facebook, Secure Folder, etc.)
Forced Stop certain Apps (Bixby, Secure WiFi, etc. - they seem to all come back after a couple of minutes anyway)
Enabled/Disabled Adaptive Power Saving (Tried both settings, made no difference)
Enabled/Disabled Auto Optimization (Tried both settings, made no difference)
Switched between Power Modes (Optimized to Medium, made no difference)
Change lock screen and home screen to a 100% black wallpaper
Ran Safe Mode overnight with ALL of the settings above (Airplane with Location and Sync Off, etc.) Still got a 15% drain overnight.
Last night after I got fed up with playing with the countless of options, I decided to Factory Reset the phone thinking that this would solve my battery drain problem. Well, WRONG. Still got a 15% battery drain overnight with only the core apps installed, in airplane mode, location and sync disabled, and other settings disabled. I did NOT restore any backups from Samsung or Google, nor installed any additional apps that did not come with the phone.
I have complained to Samsung through their Samsung Members application under Feedback. If you guys are on the same boat, I suggest we all start complaining so that they can start taking a look at this and hopefully release a fix.
If you guys have any tips or anything has worked for you guys, please let me know.

If its still draining that much even in flight mode, then something is definitely wrong. Seems like you've tried everything. Can you not get a replacement under warranty from where you purchased it? Sounds faulty.
Sent from my [device_name] using XDA-Developers Legacy app
I have had this same issue with my S7. Hence my reply. At that time I have traced it down to a certain kernel process. The only way to resolve this was to replace the motherboard. A factory reset didnt helped either.
Later when i investigated it further it was like an Interrupt request for sleep mode. Eleminating the phone going to deep sleep. Than you will see drains like this
My advice. Get the device replaced. It was the only way to resolve the problem on my S7. Hardware replacement

I installed BetterBatteryStats and got a ~20 drain over 9 hours of standby while sleeping. The phone was untouched for 9 hours, airplane mode on, location off, sync off, and other settings off.

Also, how did you manage to get your phone replaced? By Samsung? I am past the 30 day return policy so I am not sure how easy/hard it will be for the to replace my device/motherboard. What did you say to them exactly?
Reflash firmware?
Which update are you on?
After the ASCA, but before the finger print sensor update, I had amazing battery life, less than 1% per hour on idle.
But after finger print sensor update, it's about 2% per hour on idle.
Maybe reflash ASCA without the fps update? If it's possible

Spoke to someone in Reddit and he flashed his phone to the Febraury update. It still had bad idle drain.
Additional things I have tried recently overnight with no success
Disabled fingerprint
Removed SIM Card
Cleared memory cache again
I'll wait for the April update and see if that solves things. If not, I guess I'll drop by one of their service centers/genuis bars.
What a terrible experience...
Yeah that does not seem normal.
With airplane mode drop 0.2%/hours.
Sorry you are having bad issues. I would try to install U1 firmware and see if that helps.

I'm having the same issue after the recent updates on AT&T. I used to get close to 9 hours SOT and now I barely get 4. Nothing unusual in the battery stats either so I'm not sure what's going on.
Same here. The idle drain is completely insane! It's a shame that the phone suffers from issues like this when you compare it to the price we paid for it. From what I can tell the issue stems from the kernel not being able to figure out the proper frequencies for the cores in idle which leads to **** performance. I'm gonna try to flash the asd4 firmware via odin once. If it doesn't work I'm gonna get a replacement if possible. Currently I get around 4 hours of sot no matter what I do. Doesn't matter what I do which is super weird. My s7 edge which was at least 2 years old gave me a better sot more regularly, so I'm definitely pretty irritated with this. Will update once I flash over odin.

To all who has this issues. First thing to check is .. Does the phone ever enters deep sleep ....
I used this app on my S7..
Wakelock Detector. Can be found in google play.. Sorry cant post links due to my new status here.
Znalazłem rozwiązanie szybkiego rozładowania bateri zwłaszcza jak telefon noszony jest w kieszeni. W moim przypadku telefon przez noc zużywa jakiś 3% bateri a po włożeniu do kieszeni w 2 godziny 15% do wczoraj. A teraz Rozwiazanie . Wychodzimy w MENU - ZAAWANSOWANE FUNKCJE - RUCH I GESTY* - i odznaczamy opcję DOTKNIJ DWUKROTNIE ABY WYBUDZIĆ. następnie w MENU - EKRAN BLOKADY - ALWAYS ON DISPLAY - TRYB WYŚWIETLACZA zmieniamy opcję DOTKNIJ ABY POKAZAĆ na którąś z pozostałych lub całkowicie wyłączamy ALWAYS ON DISPLAY . To powinno rozwiązać problem z baterią w moim przypadku kończąc**pracę**z telefonem w kieszeni po 8 godzinach miałem 30% Baterii a teraz 70% .

BetterBatteryStats shows it goes to deep sleep 99% of the time overnight. No abnormal kernel wakelocks/partial wakelocks/alarms.
A couple of other things I have tried recently unsuccessfully while sleeping (6-8 hours) over the past week:
Safe Mode
Safe Mode + airplane mode
Safe Mode + airplane mode + cache wipe + Google services wipe
Safe Mode + airplane mode + cache wipe + Google services wipe + Remaining Apps in Sleep Mode (Battery Settings>Sleeping Apps)
Safe Mode + airplane mode + cache wipe + Google services wipe + Remaning Apps in Sleep Mode + Max Battery Mode (instead of Optimized Mode)
The best idle drain I got overnight was 15% drain over ~6 hours (~2.5%/hour)
I'll try disabling the Adaptive Battery/Auto Optimization while I have all my Apps in Sleep Mode an Safe Mode. I'll also try another Factory Reset this weekend.
If that doesn't work, I'll schedule an appointment with one of their service centers.
This sucks. My 2-year old S7 Edge still has better battery life than this.
I remember reading a post on Reddit from a guy saying he had a current leak on his faulty motherboard. Maybe you got the same issue on yours.

After reading your comment, I decided to test the phone completely off overnight.
To my surprise the battery drain was still present. From 5PM to 730AM my battery went down from 87% to 60%!!! So about ~2%/hour while the S10 was COMPLETELY OFF.
I'll be taking my phone to the service center sometime this week. For anybody else having crazy drain problems, turn your device completely off and see if the drain is still present. It might be a hardware issue
