BUG: BBS causes full CPU load after screen unlock - BetterBatteryStats

At least on my Samsung Galaxy Note 10 SM-N970F with Android 10 (Firmware PDA N970FXXS1BSLD) CPU load raises to 100% after unlocking the screen. ... caused by Better Battery Stats. (V 2.5-344)
unlock settings:
active Google smart lock
pattern, fingerprint
It did not happen after every unlock, but ~ once or twice per day.
The behavior was not reproducible. I guess it only happed if the phone was in deep sleep before.

Sometimes I had to hard reset the phone because operation was not possible anymore.
This behavior has disappeared since I uninstalled BBS.

Deep sleep problem

Hello world,
I just noticed this disturbing issue. I lost about 16% battery in one night. When I looked at battery state I noticed alot of tiny little wake moments during the night.
What kind of application can cause this? Or are there any known bugged apps that cause this?
Wakker is dutch for Wake

. THE Galaxy Notes when goes into standby (screen off) should go into deep sleep mode is a mode that allows you to keep to a minimum processor frequency to conserve the battery. Unfortunately, between the various firmware updates that we do and the various programs that we install (some of these work in backround without noticing it) can happen that the Note is no longer able to enter deep sleep mode remains fixed at 200mhz even while on table with display off.

To overcome this problem needs to be done in the following way: Deep Sleep Guide
- Go into settings and remove the following tones: sound freezes the screen and sound selection - Set the device in flight mode - Turn off the device - Remove the battery for 10 seconds - Power on the device - Wait until everything is loaded - Remove Airplane mode
And that's it. The Notes should regularly go into deep sleep after doing this guide. To check everything just to keep notes on standby for about ten minutes and see if The candidates and the percentage of deep sleep increases.
Hi
Even I face this battery issue....it is severe in my case. I hardly get 14 HRS of battery life even after about 30 charging cycles
I've installed CPU spy, I found that the CPU stays in 200Mhz, for testing purpose I had kept my cell phone untouched in flight mode for about 12hrs but still I lost more 50% of battery.
I had tested the battery by completely charging it, it just drains before my eyes . . .
I don't know if this is deep sleep issue. please help me.

1. Flash and test different kernels in case of battery drain. Some are easier on your battery than the others. 2. Use Titanium Backup to freeze or uninstall crapware. This list is a useful guide as to what can/can't be removed from your system: https://spreadsheets.google.com/spr...SENVeXlqUm5vV0E&single=true&gid=0&output=html 3. Set Brightness to low value, disable autobrightness 4. Disable or scale down vibration and haptic feedback 5. Automatic syncing of your accounts is battery consuming. Sync manually if you can 6. Set screen timeout to 15 seconds 7. Disable fast dormancy (dial *#9900# and do it from there) 8. Don't keep your WiFi/Packet Data on all the time. However, if you must have WiFi on the second you wake up your phone, go to Settings/Wireless and Network/Wi-Fi settings - once in Wi-Fi Settings, hit the menu button (the bottom left one), choose Advanced/Wi-Fi sleep policy/When Screen Turned Off. This way your connection will toggle on/off depending on your screen on/of state 9. Disable location services via wireless networks - are you travelling that fast that you need those? 10. GPS is heavy on the battery, therefore use it sparingly
And don't use Juice or any other battery 'defenders': they keep running in the background and consume your juice by trying to save it. Not to mention other problems they can (and often do) create.
Hope this helps.
Download BetterBatteryStats and look for wakelocks (partial and kernel). Google them if you don't know what they do. Then uninstall them or fix them somehow.

Am happy to say that the deep sleep issue haS been resolved.
I downloaded better battery stats, found that the process l2_hsic was stopping my phone from going to deep sleep mode. I tweaked the wifi settings and the battery life increased exponentially.
Thanks better battery stats

My galaxy note 2 battery is draining fast and the "android os" is at about 65% at end of day and now my battery last about 10 hours. I was trying to follow your instructions above but got lost trying to find the settings to remove some tones you mentioned. Which tones are you speaking of.
Thanks...

XT1064 Android 6.0 will not go into deep sleep, CPU stuck awake

I have a Moto G 2014 (XT1064) running Android 6.0 that will not go into deep sleep. I could see that the CPU was never going into the deep sleep state even when the phone was not being used and no user apps were actively running in the background. This is causing abysmal battery life as expected. The phone was updated to Android 6.0 via regular OTA updates. I haven't flashed any third party ROMs onto it at all since I bought it.
The first thing I did to investigate was to unlock the bootloader (it was still locked since purchase prior to this) so that I could obtain root access to see what was going on. This also had the additional affect of wiping the phone to stock Andoird 6.0, which I had hoped would maybe solve the problem but it did not.
My first thought was that it was a user app that was holding a wakelock keeping the phone awake. I looked at the user and kernel wakelock counts via BetterBatteryStats and WakeLockDetector, but from what I can tell it is not any user app that is holding a wakelock at all. Instead it must be some kernel level app keeping the CPU awake, but I can't determine what it is. There isn't any single entry in the wakelock list that sticks out as the culprit.
I have done some other investigative tests such as turning WiFi off while the phone sits unused overnight. This did not have any effect as the phone still remained awake the whole time. I also repeated this test with the phone in airplane mode (WiFi + cellular radios off) and again it had no affect. From this I could only conclude that it was not the wireless radios that were keeping the phone awake. The wakelock counts also didn't show any evidence that WiFi, cellular or GPS were holding wakelocks.
Here are two screenshots I took of the BetterBatteryStats and WakeLockDetector apps showing the highest count kernel wakelocks over a roughly 17 hour period:
(I'd link them in properly but I am prevented from posting outside links on this forum until I have 10 cumulative posts...)
i.imgur.com/nPAY3S6.png
i.imgur.com/5VfgFv1.png
You can see that the phone has been awake 96% of the time during this period, and that the highest count kernel wakelocks are from "event8-1877", "event9-1877", "qpnp_soc_wake" and "qpnp-vadc-e4a28400". I could not find any information as to what these entries mean or what they're related to. Whatever they are, they appear to have abnormally large wakelock counts which leads me to believe that they are related to this problem. The other thing that puzzles me is that the total time for the top four entries in that list only sum to about 2 hours, yet the phone has been awake for almost 17 hours within the same period.
If anyone has any idea about this I'd appreciate the help. I may be completely wrong about the root cause here but I'm running out of ways to debug this.
Updating this thread to say that I have also tried re-flashing stock Android 6.0 using the firmware files linked from this thread (in my case I used XT1064_TITAN_RETCA_6.0_MPB24.65-34_cid14_CFC.xml since I am in Canada). I still experienced the same behaviour where the phone would rarely enter deep sleep. It seemed to be marginally better after re-flashing, going into deep sleep about 10% of the time over a 12 hour period or so, where as before it was only going into deep sleep about 4% of the time during the same period. This still doesn't solve the problem though.
Now I am thinking about downgrading to stock Android 5.0.2 and see if that fixes the problem since I don't know how else to diagnose this.

ssp_sensor_hub_wake_lock - need to catch this battery thief

Hello there . Using Better Battery Stats I found out about this process which takes my phone out of Deep Sleep for about 5 minutes every hour. Totally annoying.
My phone is seriously trimmed down. I'm very strict when it comes to what is running. Data connection is almost permanently disabled, no weather widgets anywhere (that I'm aware of), no sensors active, extremely few processes in background, and even those that are have been thoroughly vetted. I'm using Disable Service / Greenify & Autostart to seriously trim down on whatever is running.
I did notice that when the phone is in Airplane mode, ssp_sensor_hub_wake_lock is keeping my phone alive "only" about 1 minute / hour. That is still too much, since I do NOT have any sensors that should be active at that time.
CONCLUSION AND THE ACTUAL QUESTION:
How can I investigate WHAT PROCESS starts ssp_sensor_hub_wake_lock OR ALTERNATIVELY get any logs / debug that could lead me to the culprit.
Thank you in advance!

Is the fingerprint scanner enabled while the screen is off on stock rom?

After unboxing and charging my new Note 9 I immediately rooted the device and flashed a custom FW.
Can a person on stock ROM please clarify these questions for me:
1) Is it stock behaviour that the fingerprint scanner on the back is always on while the screen is off?
2) Does this feature impact battery life?
3) If it's stock behaviour how do I disable this? I tried changing the secure setting "biometrics_auto_wakeup_enabled" from 1 to 0 without any effect. But maybe there is another switch? I don't know.
Thanks for any help!
1) If I remember right, I have not changed any settings related to the scanner being enabled/disabled while screen is off, i.e. it would be at "default". I haven't even looked for such. For me, it does unlock directly even when display is off. (Edit: fingerprint seems to unlock from any state before homescreen, except in the lockscreen note writing mode.)
2) I haven't measured battery life yet, let alone looked for changing the feature's behavior for another measurement, so I can not really tell. However, standby battery life seems to be ok. I'm using the phone with very varying levels still, so hard to estimate well, but I'd estimate from the early daily %-drops that standby time is at least 4-5 days. So, I guess the feature doesn't drain the battery that much.
Just a small follow-up, as I finally got a decently "normal" (for me) day and a half with the phone, only one short call, text message, maybe 10 gmails received (but mostly read on PC), a bit of "usage" with screen on time probably less than 15 minutes in total.
Seems I could get about 7.5 days of standby time.
Screen settings don't matter much in this scenario (as the display is off most of the time). Other significant settings are: wifi off, BT off, 4G LTE always there, GPS always available, NFC always ready, fingerprint sensor always waiting for finger, the only extra apps that could be battery hogs are Flowdock and Steam apps (both seem to behave nicely, Flowdock was nasty on my previous phone). Using the LED cover. (Quite the "default" setup with a relatively small number of installed apps or changed settings.)
In a way, that result is good. But on the other hand, with similar setup (minus Flowdock and LED cover, fingerprint sensor only works when display on, but add an extra email account on samsung email app with polling checks), my Galaxy S5 was getting about 6-7 days standby time, too, and that with its original battery (and the phone was bought pretty much the day when it came available here). Note 9 having much larger battery, and presumably better SoC (at least they always claim lower battery drain in idle from each CPU after CPU generation), better Android version... kind of "meh" result from Note 9. However, I did tighten some settings on that S5, like reduced email check frequency and such, which I have not looked for on Note 9 yet. And possibly will not look for, that 7+ days is good enough for me.

Factory Reset does NOT solve S10 Battery Drain (15-20%) when Idle

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
