Battery life analysis: myths and reality

After going through lots of pain with my Vibrant (Galaxy S) to try to maximize battery life and hearing discussions on here about removing this or that to extend the NC’s battery, I thought I’d apply the same analysis techniques I learned from the Vibrant to the NC.
Thanks to many smart people (BruceElliot) in the Vibrant forum, I was turned onto an app called System Panel, which gives historical monitoring of battery usage and the apps that consume them. Here is my analysis.
First, I reimaged my NC and returned it to factory state just to be sure none of my user settings would muck this test up. Then I updated to 1.0.1 and used AutoNooter to root. Next, using the paid version of System Panel, I set up monitoring and left my NC on over night (no use). I looked at it this morning. The first picture (SummaryBarGraph) shows the historical battery usage for the past 8 hours (ignore the spikes at the end, I was actually reading a book). As you can see, there are some micro spikes while the device is “sleeping”.
Next, I looked at the top apps that have been consuming power. The second picture (TopApps) shows the apps the percentage of power they consumed over the past 8 hours. As you can see, it is very little. If I click on “System Processes”, you can see more processes running underneath it. The third picture (SystemProcessDetails) shows that there are just a handful of apps. The top one is “Suspend”, as it should be as this is when the devices is sleeping.
My conclusion:
If phone or mms or other telephony services was one of the processes listed, I could see how removing the apk would have an effect on battery life. The fact that they are not listed proves those apps have no bearing on battery life. While removing them probably does not hurt, the "increases" people see are fictional.
If you feel the need to remove those apks, I would suggest getting TitaniumBackup and just "Freezing" them. You can unfreeze at anytime with out adverse effect and not worry about screwing anything up.

Yep, System Panel works great, I've owned it for months and have it running in Monitor mode 24/7 on my Nexus One and the NC.
I seem to always have 1-2% CPU going when idle on my NC, but I have several widgets which are probably doing something nearly all of the time at any given moment...
Regardless, I see about .2%/hr battery usage in suspend and a nearly constant 8%/hr while the NC is in use regardless of wifi, and with the screen at maybe 5-10% brightness, not sure what the exact level is.
Thanks for taking the time to verify that the phone related apk's really seem to be a bit of a false positive when it comes to actual battery usage. It could be that with a heavily configured device partial wake consumes more battery than a device which doesn't have stuff running, widgets, etc... That'd be a bit hard to determine I'd think, however.
Regarldless I renamed the phone apps a week or so ago, but I am inclined to think there's really no difference on the battery life in the end.

Thank You. I too saw no improvement in battery life by removing the phone and telephony apks. Not having the phone apk caused reboots when i put the NC to sleep. Reinstalled the phone.apk and reboots stopped. At least in firmware 1.0. I have not gone back 1.1 yet.

Great Post, there were many questions of whether this saved battery life or not. Thanks.

Nonsense, the phone apk's have nothing to do with the reboots from all of the observations on the long thread about this.
Why would you mess with 1.0.0 FW? It'll automatically update you 1.0.1 and hose your install....

Thanks for the info, makes sense these app wouln't have any impact in the absence of the related hardware.

Reading the other threads is what got me thinking about it. Its not the phone process that kills the battery, its the radio. And if the Nook doesn't have a radio that is activated, than how can it be using power?

It's not the absence of the phone.apk but the way it is removed. If there were any system dependencies on that file and it all of the sudden went missing, I could see why he'd get some FC.
It's like deleting a exe from Program Files instead of using the uninstaller on a PC.

Two reasons I'm still on 1.0:
1. I changed otacerts name and, after several weeks, there have been no automatic updates, crazy system restores, or Bigfoot sightings.
2. Dolphin HD successfully changes your user agent (all except Android) on 1.0. People on 1.0.1 have reported that none work.

When you say freezing apps do you mean using adb to disable the package?

No, TitaniumBackup has an option to freeze. It's different than using adb.

Ditto. I'm on 1.0.0 with otacerts renamed...no auto updates, crazy re-initializations/reboots, etc. I'm leaving it alone for now.
Thanks for studying this. It sounded a little too good to be true.

Did you have softkeys installed? Mine was rebooting too when going to sleep with wifi on and it stopped doing that after I removed the softkeys app thanks to a comment I saw in another thread. Replaced with Button Savior and no reboots with the said apks disabled (I didn't remove them, just renamed).

I did the same thing based on the post in that other thread and I'm up to 20 hours without a reboot so far. Keeping my NC on my desk at work today to listen for reboots

What about trying this with those two files renamed and see if that changes the battery usage?

I thought about doing that but the issue is that there is no phone process running for me to monitor. Doing the same process on my Vibrant shows the the phone process is indeed running and using power. Here, nothing.
I might do a comparative test to measure battery life drain per hour while idle, but I don't think its necessary at this point.

But is the System Pannel deserve your trust?

[Guide]Android System/OS Battery Drain FIX

After Installing Custom Mods and rooting on Oxygen OS I was experiencing a Android System battery Drain .
Also in custom Roms based On OOS I also had the same problem.
I was draining 35-40 percentage of my battery in a charge cycle.
I searched alot past 2-3 days on my phone to see which process is causing this Drain problem.
I found many but stoping them didn't fix it .
Finally today when I found that after SuperSU was installed
It was causing the Drain so I found a fix for this
Fix for all Roms having this problem
-Go to SuperSU app
-Settings menu
-Enable trust system User
-and enable grant permission during boot
-Then put the phone on flight mode and wait for it to cool down.
If this doesn't work
-Try setting default access to grant
-Enable MultiUser access
Hit the thanks button if this helps
Also tell me if this helps in the comments
Remember to follow all steps

Doesn't work still battery drain and phone always warm

Thanks for sharing but both solutions are security risk. Maybe Magisk is solution till SuperSu is fixed (hoping that it IS the culprit).

Try to delete all of the mkv files. That helps for me. No battery drain at all

i would say "kindda" help. cause still android system drains. but, a bit less then before. i would like to see some more days.

I switched to Magisk and drain is still there so reason is something else seemingly. It has something to do with FW/Modem. We all need to deluge OnePlus with requests to fix this mess.

Helps me
My current battery cycle

For me clearing the Google Play Services database solved the battery drain.
Apps,
Google play services
Storage
Manage Space
Clear all data
I then remained on that screen and restarted the phone into recovery without returning to the launcher.
In recovery clear cache only.
Reboot
Since then I have had no problems at all (though I am running complete stock no root)
No data is lost but you will have to add cards to android pay and set a couple of other items when prompted (like default backup account etc).

I mean no disrespect to the OP when posting this..
Isn't setting default root access to "grant" a crazy big security risk? Potentially malicious apps could reboot recovery in the middle of the night, flash some REAL spyware and feed back all your passwords without you knowing and could compromise your online accounts, still have to be installed first or some exploit would have to be found, but it just seems the risks outweigh the benefits.
Are you sure it's not another app you've consistently installed? F2fs? Clean installs + factory resets? Checked your signal strength lately? Wi-Fi + Bluetooth scanning? Facebook/whatsapp/etc installed? Google location history? Different versions of twrp? Titanium backups? Uncheck the the option in android settings to Backup and restore android apps? Installed several versions of older supersu?[ R4, r3, r2, r1, r2d2?]Franco kernel? [HIGHLY RECOMMEND. All the other kernels I've tried leave my device pretty warm, but franco keeps it cool), or Anoint your phone with luxurious oils, passionately bathe it and whisper sweet things into its microphone? [References here->
]
I just wanted to make my thoughts known, some newer users to root might come by, try and follow these steps hoping for SOT gains, and needlessly compromise their phone in the process.
If you persist in believing cf supersu is the root cause (that's a knee slapper!!) I think trying another supersu might be a better way to go than ticking all those options. Say like, phh's or CWM.
Again, I mean no disrespect to the OP. Just my thoughts.

Forget about SuperSU, You guys have no idea what causes the andriod OS drain after flashing.... So stop blaming kernel, SuperSU, gplay services etc.. The answer is out there in forums.. Feel free to browse and search for it...

Read it carefully though.. Explains why andriod OS drain battery more in first days (Not cycles) after flashing rom.. More apps, more the drain..
Tl;Dr for lazy people out there... Andriod os drain is present because Google itself has changed how andriod works..
On side note, I don't spread bs.. I just put my observations. It is upto people to fix it and accept the truth or get emo over it..

I read this post from Rovo long ago, and I of course was taking about abnormal drains they were occurring long after reinstalls or new ROM flashes. It's well known, the rebuilding of caches etc.. Anyone complaining before this incompressible period should be treated like you do. Also, still thanx for minding sharing something at least and on a SECOND side note, read again, I never said you spread bs, pretty much the other way around, i was just suggesting you enlighten us instead of "spraying people with their own bs" like for example, on the Blu spark thread where I know you were putting whiners back in place. Cheers.

I am using magisk, so what about me?

Getting Greenify to work with the Fire 7

So I didn't expect it to have the greatest battery life in the world. I'm coming from a Nexus 7 2013 edition (just wanted something cheap to carry around -- I'd be very upset if my Nexus 7 was dropped and broken or stolen in public whereas this $30 tablet won't exactly cause me to lose any sleep if it does, but I need to be able to read and otherwise pass breaktime at work) so I'm used to it lasting almost a week on a full charge since all I do is simple stuff like reading with a relatively low backlight even. I noticed my new Fire 7 is going down so much faster that it will surely be a problem (I guess 20-30% a day?) Now, of course, the Nexus 7 has a significantly larger battery. However, its ~5-7% compared to this thing's ~20-30% is not to scale. One big difference though is the Nexus 7 gets to run a clean LineageOS setup with a rooted Greenify (actually I have Xposed, but lately the module doesn't work without explanation. That's an issue for another time though.) The battery is purportedly a 2980mAh versus the 3950mAh in the Nexus 7, so at 75% the capacity I wouldn't expect it to get 1/4th the run time. I'm hoping Greenify can help. Unfortunately, Greenify is not working at all.
Firstly it seems you must manually grant a bunch of permissions for certain things. During initial setup it tells you to grant one and sends you to the settings, but it doesn't send you to whichever part of the settings it actually means for you to change. (I'm guessing something that isn't present on this thing's modified non-standard system settings app.) Now, they give you instructions on how to manually grant certain permissions via adb, but it doesn't mention that particular permission. It seems also that the accessibility service that it uses for hibernating isn't actually working because it pops up a message. However, that could be related to the more serious problem at hand: it doesn't work at all. When I press the hibernate button, it does nothing. Literally nothing. (Which makes me wonder if it's just saying that because of its failure when it tries to automatically hibernate.) Without root access obviously it is much more limited in what it can do, but it should still do something. The guide only has you grant DUMP, READ_LOGS, and WRITE_SECURE_SETTINGS. These are intended for features like accurate app state detection rather than basic operation though. I have no idea what it wants on initial setup since it's not specific at all.
Actually, I think it's not actually granting the permissions at all in the first place. I manually grant those three via adb as it says and pm doesn't say anything back. Regardless, Greenify is unable to do anything at all -- it never hibernates any apps even when run manually. I'm not sure how effective it will be without root, but I'd still like to get it working if at all possible. Still, it officially supports rootless systems, so I don't really understand why it's unable to do anything at all. Even the most basic functionality should work at least (though if it only acts as a task killer it may do more harm than good. Hard to say since I can't even get it to do that much even.)
Any idea what I'm missing?

in my experience, Greenify doesn't work too well with these tablets. If you are on 5.4.0.1 or later, I would try Brevent.

I'm on 5.4.0.0. Given how much more restrictive 5.4.0.1+ is I've removed the OTA update apps so it won't go up.

Just a note: on the 7 tablets, you can downgrade from 5.4.0.1 back to 5.4.0.0.

I know that. So?

"Battery usage data isn't available" /data/system/batterystats.bin -daily.xml etc

"Battery usage data isn't available" /data/system/batterystats.bin -daily.xml etc
Got a "new" left over stock Nexus 6 through Ebay, installed lineageos 15.1 nightly, MindTheGApps, root, radio, bootloader. Everything seems to be working nicely, except the Nexus 6 runs pretty warm rather quickly after using it, and I find that the battery is draining pretty quickly. In standby mode it doesn't drain quickly.
But I get no access to battery stats in the settings, because under Battery, it says "Battery usage data isn't available".
There has been talk about this before, but it's all pretty wishy washy. Some people apparently had success by using recovery to clear the cache. Others deleted the /data/system/batterystats.bin file using the battery calibration app from the play store (I know I know, there is no such thing as "calibrating" a battery, but it's just used a tool to delete that file in this case), the one that happens to mention batterystats.bin in its description. Others simply waited a while, and others ended up reflashing. Short of reflashing, nothing has worked. I've tried to manually delete that bin file using Termux and then rebooting. I can see that the file gets regenerated upon boot. What is the reason why the Settings/Battery feature can not show any of its details?
Aside from batterystats.bin, I also see batterystats-checkin.bin and batterystats-daily.xml. Does anyone know anything about those files, and could I perhaps delete them all (or rather, move them into a backup folder so I can place them them if needed), without bricking my phone?

Try using acubattery for some days and see what condition the battery is in. Even if the device is new, left over stock, the battery might really be damaged.

I'm installing that now, thanks.
I just found this: (I'm not yet allowed to post links), youtube: v=dZL2LDAg5cs
So, in developer mode, Android can produce a bug report zip file that you can upload to a special website, that is able to pluck detailed battery usage data from. I wonder if there is an app that can do that instead. I suppose that app would not be able to directly show this kind of detailed information, but would have to be pointed to a zip file that the built-in bug report developer feature stored, eg, in the Downloads directory.
All this is only needed to troubleshoot what the cause of the battery drain is. But yeah, it may well be that the battery is old and stale or whatnot, even though it has not been used for like what, 4 years since it was manufactured. Interesting to find a "new" unopened sealed Nexus 6 on Ebay in 2018 though...

In your first post, you indicated you installed bootloader amongst other things. Did you mean boot? As in a third party kernel? If you really meant bootloader, would you go into more detail on that.
When you first turned on the device, what version of Android was it?

I followed the official instructions on how to install LineageOS 15.1. Part of that was flashing the bootloader using fastboot.
I just checked my phone again. It still says "Battery usage data isn't available.".
Accubattery was showing many details on how different apps were using power, but now it's only showing 2 entries. One for settings, and the other "Trebuchet" which I think is the camera app that comes with LOS. Oh, AccuBattery itself spontaneously joined in the list.
Anyway, I don't expect Android to work all perfect, because it's clearly one big pile of make shift goo. Nothing ever works right on it. You have to literally babysit the damn thing fighting problem after problem after problem.

Trebuchet is the LineageOS stock launcher.

i have this same problem with my Alldocube x, it drains pretty quickly and heats up enough I had the urgency to shove it into the freezer, sometimes I stick a block of ice cube on the back metal to counter the heat, I am only using youtube.
Along with this annoying heating problem is the battery drain and no battery usage problem.
I also tried resetting, reformatting, clearing cache etc.
im loving the Tab S4 screen on this and I cant go back to petty LCD tablets.

Question What's is the best firmware for battery ?

Hi i have a question my battery is very bad 3 4 hours normal usage and I must go to charger my oxygen firmware is C.30 its my last oneplus phone :/

So long as it's a clean install, they should be all very similar... I've always been able to go past a day / 2 days depending on my usage.
Your apps will determine how long it'll last, if you're constantly on social media, playing games and hammering the battery , then it really doesn't matter..
I'm still on android 12 and I get about 8-10 hours SOT over about 40 hours..

I try make a clean install for games i have steam deck my usage is normal Messenger Facebook Instagram sometimes YouTube tiktok but 3 4 hours and my battery have 20% battery. What's is the best app for backup all apps ?

If you're rooted then swift back up... Bare in mind that all those apps you just mentioned are very heavy... So yes your battery will always be poor..
I made a comprehensive list of things to do to get the best from your battery.. it's in the battery life thread, have a search for it..

Thanks

Interesting. I noticed my battery life took a nosedive after I let it update to 13. Some folks told me its just coincidence but I think 12 was better on battery.
I am not rooted, is there any way to back up apps so I don't have to find and login to them all again without root?
I have things like smart home applications to control outlets, my DJI mavic app, control for an LED sign, my air conditioner, etc that I'll never remember all the logins to if I format right now.
I know from experience that I'll forget what they even are until I need to use it and then spend the next 30 minutes trying to remember not only what the app was, but also what email I used as a recovery for lost my password.
I'd give a fresh installation a try if I weren't afraid of it being a multi day ordeal to put everything back.

If you're not rooted then no I don't think you can back up your apps in their current state like you would with let's say swift or titanium, but you can restore them using Google.
I think you need to take a look at your situation, it's always a faff when you full wipe.
Personally I would always root. I use two banks which are just fine with root.. I need root for my mods and for a few other apps I use that require it, it's not a battery issue, In fact quite the opposite as I can tweak my device using a kernel manager whilst a non root user won't be able to, not to mention adaway and swift backup.
I do a few things to make sure everything works..
1. Allow Google/chrome to remember my passwords for all sites, if I wasn't going to do this then I'd make an offline list of them and then go from there or even use 1password, that way you only have to remember 1 whilst it'll last every single site for you.
2. As im rooted I use the mod I posted to allow free back up to Google photos so I don't have to worry about media.
Same goes with my contacts.
3. Finally copy out critical files that I'd otherwise miss, I do this locally via PC, like the swift back up folder after the main back up, then others like emulators and their folders as they contain settings to my custom setup, my nova custom desktop back up, my downloads folder or categorise the contents into their own folders, anything else I can think of that I'll need (you get used to your routine, most of the time it's simply a case of adding the additional files that are different from your last back up, the more you do it the quicker it gets)
4. Get my boot images ready (patched and stock) a copy of the full firmwares I'm going to plus what I'm on and a note of both unless I can remember.
Done.
PS: reason I'm suggesting looking into it is you could be forced into it by something as simple as an error or device fault, so best to get your ducks in a row..
Overall I think I've seen better battery life from 12 if I'm being honest, but again it's down to the apps you use, what used to be quite light on android 12 may not be as friendly on 13 and vice versa, it's extremely difficult to get a bearing between devices as no two are the same, plus the apps each person has is so different.
If you really wanted to test then you'd need to remain as the device was then run tests on solitary apps and see what was lost over a period of time.
Also bare in mind that the device will begin to remember your habits over time too which helps write a lot with battery on both firmwares but it does take time to happen, a week I would give it.

Swift backup is the best backup app for rooted phones. You can back up everything completely along with its settings.
