Battery savings guide

Hello, i use Dalingrin's kernel (6/30) and CM7 nightlies (121 currently).
Sometimes deep sleep is nice for my battery, sometimes it doesn't save energy.
It's life but i need a few days between battery charging.
so i decided to add a few workarounds, here they are:
1. Airplane mode everytime + wifi on/off when i need it. Only ten seconds to activate/deactivate with CM7 status bar.
2. Battery widget monitor: it enables history of battery consuming. Very good to act that deep sleep is effective or not.
3. uninstall applications which sychronize when nook should be sleeping: K9, DSPmanager, hotapps, appbrainz.
3. Advanced task killer pro: Crazy mode when screen is off. Very nice for last applications.
Of course, you are welcome to comment those tricks and to add some

I guess it depends on use, but I'm on day 3 on a charge, running at 47%. I just have the screen at 15% most of the time, and I don't disable sync. I mostly do reader, email, internet, so that might be part of my success.

1 is probably not a good idea, since sometimes Airplane mode sticks.
2 has nothing to do with saving battery, but okay..
3a does nothing if there is no network connection (assuming sanely written programs)
3b is stupid and shouldn't ever be used.
You want to save battery? Turn off wifi when the screen goes off. You can do this automatically with Setting Profile Lite or Tasker, probably some others. I've found that the wifi sleep setting doesn't do anything for me, I can continue to ping the NC for 10+ minutes after the screen goes off so clearly the wifi is still up.
And watch Spare Parts partial wake locks and see if you have any misbehaving apps. I find that Maps with Latitude enabled misbehaves without a network connection and constantly is trying to update or something, so I cleared data on Maps to get out of Latitude on that device. CPUSpy will also show you how much deep sleep is ongoing.
The NC is going to use at least 10%/hr at low backlight doing simple tasks, I've seen it use up to 25% overclocked playing games.
While asleep it uses about 1% every 3-4 hours. Could probably do even better if you don't have a boatload of apps and widgets like I do.

Grab "Where's my Droid's Power" or whatever the application is called, and see where all the power is going.

He said the battery widget is to see if it is asleep, and see what the consumption is like.

Hello,
You are right about battery logging.
i have to test the two applications you mention both:
1. "And watch Spare Parts partial wake locks and see if you have any misbehaving app"
2. "Where's my droid power".

[Q] problem of 4.0.3 ROM German version, unrooted

I have encountered a problem and need some help pls...
I recently flashed to 4.0.3 official rom German version (not leaked version), unrooted. I downloaded the firmware from samsung-updates.com, upgraded the phone, everything worked fine.
However, i found out recently that sometime if i left phone idle, the battery drains really quickly. say if i charged it up to 100% and left it over night, next morning, it will only have 60% left.
firstly, i went to Settings, then Battery, i found out even when the screen is OFF, the is still keep on "awake" -ing, i then downloaded CPU spy, i can see that when the battery drains quickly, CPU was constantly operating in 200MHz, something must be running in the background all the time.
I also downloaded betterbatterystatus, i have checked the wakelocks, everything worked fine.
I wonder if any of you guys have the same problem.
This does not happen often, and i believe restart the phone can "cure" it temporarily, but it will come back you dont know when...
btw, i have turned off google+ services.
please help and excuse my English.
Thanks

You have Wifi on? Or added a new app recently? I usually reboot my phone when I install a new app since last time I installed a new app there was battery drain issue.

This helped making my phone deep sleep and decreasing battery drain
0.go to settings > sound and turn off touch sounds and screen lock sounds
These steps stop the kernel wakelock 100% problem:
1.turn on aeroplane mode
2.turn off device
3.take out battery for 10 seconds
4.turn on device
5.wait for everything to load
6.turn off aeroplane mode

Take a look at this blog article

I had the same issue and solved it by doing the following steps:
1. Allow a charge to 100% to occur
2. Before you unplug the charger, unlock your phone to the homescreen
3. Restart your phone
After doing this, I noticed my phone goes into deep sleep and my battery lasts longer throughout a day.

Mine did that, but I did the charge up, airplane mode, shutdown trick and it
fixed it.
Got a friend on an older galaxy captive, he finally got around to upgrading to GB,
and his was rooted before the update and he forgot to unroot before the update.
After the update, part of the old root program was running all the time sucking his battery down. After he figured out a way to get rid of it, the problem with battery drain stopped.
If the charge, airplane, shutdown trick doesn't work, download something like CPU Spy and see what's taking up the battery. Could be something left over from GB still running.

I was having a heating problem when charging the device (Battery temperature above 46C) and huge battery drain.
This was fixed after following the above steps.

Ways to improve battery life?

Sorry for the long list of screenshots above, and also for creating a new topic, but didn't want to spam the normal board for battery discussion.
Anyway, I have the N920I model of the Note 5, using it on Telkomsel in Indonesia, and getting average 3+ hours SOT on this device, which I think could stand to be much better, given I got around the same figure on the Moto X 2014, which has significantly worse battery life according to most counts.
Here's my settings:
Screen brightness 60%, auto
Sync on
NFC off
Location high accuracy
Bluetooth on from 8 to 3.30, then off for the rest of the day
Connected to an Asus ZenWatch 2
Wi-Fi on from 4 to night, from plug out in morning to 8
Here's the list of apps I disabled:
And here's how my usage goes:
* Plug in when I wake up, then out at 7-ish.
* Get to school and let My Places switch to "Work" mode, where it changes the Bluetooth, Wi-Fi and power saving settings and turn off data before starting the first class.
* Turn it on between classes to check for new messages.
* Leave at 3-ish, and get home, letting My Places change the settings back to normal. At this point, the phone is usually at 70% with an hour of screen on time to report.
* Use it periodically throughout the rest of the day, switching between WhatsApp, Snapchat, Netflix, Chrome and YouTube.
* Plug in at 8 or 9, then plug out before I go to bed, topping up what's left in the morning.
It's a fairly light usage pattern, which reinforces the point that this phone should get more than just 3 hours. Any specific app you're seeing here that might be putting its toll on battery life, or a specific setting that you can advise enabling or disabling?

Just try counting how many threads there are about battery life in this section. A lot! I, being one of the victims of horrendous drains, have tried everything. If you keep the device relatively clean(software) and it still drains then there is only one thing you can do. Wait for the marshmallow. I'm sorry but that's what it means owning a samsung device.

try gsam battery monitor. It may give insight into what is going on....

Already did! But Android OS is always the top consumer.

thanks!

As Octa_core mentioned, there are quite a few threads about battery life already. They might be of benefit if you haven't already looked through them.
Here are a few things you might try, if you haven't already.
- Turn off location high accuracy, or only turn on location when you need it (if you can)
- Turn off location history
- Turn off Always Allow Scanning in Wifi advanced settings
- Turn off S-Pen settings (alerts, sound, vibration, detection)
- If using Google Fit, disable activity detection in settings (this definitely helped my idle drain)
- Turn off anything you don't need to sync on your Google Account
- Disable enhanced LTE services
- Turn off Motions and Gestures you don't use
- Set touch key light duration to Always Off (under Display)
- Turn off Smart Stay
- Set Screen Mode to Basic
- Use a darker theme
- Try disabling some apps, especially S-Finder (may require Package Disable Pro to disable some apps)
- What does your signal look like in GSam? Some drain may be due to poor signal.
If none of that helps, then uninstall or disable (probably will need Package Disable Pro to disable) all apps you installed, and I also recommend that you disable S-Finder. Turn off all radios (location, NFC, bluetooth, wifi, even data) other than cell. Reboot after those changes. Monitor and see how idle battery drain is. After I did this, my idle drain was around 0.4% per hour. Then you can gradually enable radios/apps, only 2-3 at a time, reboot, and see how it impacts idle drain. Continue until you find app/radio that increase idle drain.

(if exists) what is the normal awake time (screen off)?

Hi all,
I've tried to find somewhere a discussion on this topic. What do you think of it?
Here it's my report:
12h4m Deep sleep
54m47s Awake (screen off)
26m11s Screen
Honeslty, I don't know if it is correct or not. Basically, I find this statistic of Awake (screen off) as a Key Performance Indicator (KPI) to analyse whether your system is working correctly or not. I've seen many people going ahead to the partial wakelocks screen. I believe it is better to make an initial diagnosis using this KPI.
My point is that I feel people is too obsessed with wakelocks but the main point is whether your system is working in a normal awake (screen off) ratio.
Summarizing, what is a correct ratio of awake (screen off) time?. In my case it is under 10% of the deep sleep time. Of course, I understand there are other variables like if you check screen very often then deep sleep is achieved less time. Or, as in this case I post, 7h of those 12h, the phone was in plane mode as I was sleeping.
Thanks for participating

BUMP! I like to know aswell since i have 25% awake(Screen off) which i believe is too high but really dont know.

No, what you have displayed is not correct. In a proper dump file (Which is taken while the device is idle), your 'Screen On' time must be less than one minute.
Your 'Screen On' time is 26 m 11 s.
That means you used the device, which throws all other device statistics off, rendering your findings ineffective.
What you have displayed is 'Usage' mixed in with deep sleep. 'Awake' time will vary, but means nothing if your device is in deep sleep the entire time. Airplane Mode simply kills all device radios, it fixes nothing. To gain an accurate picture of what keeps your device from sleeping properly you must:
1. Charge device to 100%
2. In Better Battery Stats, you should have 'Unplugged to Current' as your start point. (For Beginners)
3. Unplug the device.
4. Let the device idle for 6+ hours. Do not touch the device, put it on a table and walk away.
5. When completed, save the log as Dump File (Default setting). The log is saved in the root of your SD card as a *txt* file.
That log will tell you what happens when your device sleeps.
1. 0% /h drain, or lower is acceptable battery drain.
Below is an example what proper deep sleep while idle will resemble.

I have done these steps and identified those kernel wakelocks:
bam_dmux_wakelock (*api*): 1 h 34 m 13 s Cntc/wc/ec)5285/0/0 20,4%
[timerfd] (*api*): 49 m 3 s Cntc/wc/ec)20174/0/0 10,6%
What steps are to do to reduce these wakelocks?

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

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

Oh, seems like the same with mine, the fingerprint update
