guide to control your battery and keep build smooth

There lot of interrogations and frustrations concerning slowdowns/battery drains on Android, sometimes not really fair.
You need to control your build and knowing what is going on into it, because most programs you install live from their own and can downgrade your stability and your battery performance.
A detailed guide is provided here in order to have a good battery drain with very smooth and reliable android experience on Hd2, gathering tips and advices users need to know when they come to this Os or want to improve it durably.
Following this guide, you will be able to have hundreds of apps into a super smooth, stable and battery friendly android build.
Most importantly, without transforming your smartphone into a dumbphone :
- Wifi and sync always on
- Mails checked every hour
- 148 applications installed (no I don’t need them all ;-) )
- 6 widgets running on the screen or in background (check screenshot) : Folder organizer, News, Facebook, Current widget, Powersnap, switch pro, pure calendar, pure grid calendar.
- In standby, it can last for 4 days :
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
- Smartphones are more and more looking like a laptop, so I consider that 5 or 6 hours with the screen alight is good.
The assumption is the battery drain can be affected by several factors:
1) Screen brightness.
2) Memory management if wrongly configured
3) Program launching in background if wrongly configured
4) Program updating in background if wrongly configured
5) Build and Kernel
6) Wm rom, radio, Sd card, Cpu in standby
7) Extras : Backups, customizing etc
Once you have the good utilities and understand how it works, it is easy to setup and need no more tweaks, unless you install new apps.
To keep a battery trace, current widget with logs and battery snap are mainly used.
1) Screen consumption
The screen battery consumption is huge when we use the phone. It was the same on windows mobile, and was to expect when buying it with that huge size.
Therefore, the screen brightness is an important factor to deal with.
In order to keep a good battery life when your phone is on, you need to keep your phone around 300 MiliAmpers or less. You have to keep in mind that a 75% brightness = 500Ma.
The best behavior is to keep your screen :
-25% brightness at home, with no sun.
-50% brightness mostly of the time
-75% and 100% brightness in very rare occasions with direct sun exposition.
In order to swich fast between this settings, and since we don’t have for now a functional kernel with auto brightness, using a brightness widget is recommended.
I personnaly use “Brighness level”, and launch it by swiping a dock icon into launcher pro.
Ps : Take care to not press 0%, or your screen will be completely dark. You can revert by guessing where the icons were, but it is tricky.
2) Memory management
In order to keep your hd2 fast and battery friendly, it is better to keep your phone with more than 200Mo free ram (when you are not using it).
There is a great free program for that, called task panel X. With it you can choose which program you want to close every time you put your phone in standby.
It is very important that you choose well the apps that need to stay in memory, and the others.
It is pretty simple: Keep the widget you use and system apps. Discard all the others by including them in the autokill list. It is a bit long to do if you have hundreds apps, but you have to do it only one time.
Example:
3) Programs launching automatically in background
You need to control the apps you install. Problem is that some programs are launched automatically into your memory at any time. I was surprised to see that programs that don’t need to be to stay in memory (when I don’t use them) launch by themselves at anytime. “Mabilo wallpapers” was the best (or worst) example.
You need an app to control that. I recommend “Startup Auditor”, and set carefully wich apps that can launch by themselves or not. Same as with task panel, just keep system apps and widgets. You can keep too your mail app. If you don’t use the Gmail app program, remove it from the list.
You will see into task panel that very few programs keeps running despite of that. You have to question yourself: “Ok this one is great to find new wallpapers, but it is constantly running in my memory and I don’t know why (suspicious) -> Do I really need it ?”
4) Programs updating in background
Programs that you authorize to launch automatically in your memory are often in order to update automatically things. (Mail, weather, facebook, tweeter etc…)
It is important that you know what they are, and where are located their update settings in order to not to waste uselessly your battery. Checking mails each hour or two hour is sufficient. Checking every 15mn cause obvious battery drains.
For most needs, manual updates for social apps or weather is sufficient, because it take only two seconds when you want to see them. If manual updating is not available, choose the longer updating interval (one day for example)
5) Builds
The following is based on my personal opinion; you are free to use and test every build you want.
First, i don’t recommend using sense builds due to personal bad experiments. I had crash and a lot of slowdowns, but most importantly it was battery draining due to all the htc third apps hard coded into. It is a build very hard to control.
I use and recommend a shubCRAFT 1.5 with stock Cyanogen mod 6 Final :
http://forum.xda-developers.com/showthread.php?t=740963
Don’t forget to download the 1Go user data file in order to install more apps.
It’s a build very fast to boot, smooth, efficient and highly customizable. The kernel provided in it is good for now.
Launcher Pro is used here, very smooth and easy to customize.
6) Wm rom, radio, Sd card, Cpu
SetCpu can be usefull, depending on the kernel you are using. There is a lot of threads on it, the most important setting is to downclock your cpu at standby.
Sd card
There is some evidences that your sd card can drain your battery. If you follow this guide and still have battery drain, it can be the cause. Check into this post :
http://forum.xda-developers.com/showthread.php?t=781433
I use a Kingston 16Go class 10 micro sdhc card with no issue.
Registry tricks :
I had before these regitry settings into windows mobile rom, no idea how it affect Android :
http://forum.xda-developers.com/showthread.php?t=585729
Radio
I use 2.12.50.02_02
Ppp or rmnet
I don't have dataplans, so i can't tell about rmnet or ppp battery drains, but my suggestions to users who use it, is to activate it when you turn on your phone or every one hour, with a third app like Tasker.
SuperUser permissions
Polo735 suggest that, in rare cases, the superuser permissions program can be faulty and need te reinstalled, otherwise it drains your battery.
Symptoms are : When installing an app requiring superuser permissions, no pop up granting it appear.
See his post here
7) Extras :
If you like the screenshots design, it is the stock Shubcraft froyo framework with a custom black toolbar form manup revolution theme, compressed for speed. You can download it bellow and copy the file to /sdcard/Android/root/system/framework/ You have to set some custom colors into the cyanogens mod settings:
-Toolbar color in black
-Clock color in white
-Date and toolbar title in white.
Have fun !

Nice one, thanks!

Na, I use data most of the and with it turned on I get between 7 and 10 mA in standby,
Nice thread was already using most fixes just different apps, any chance of a link for task panel x can't find it on market.
And like the brightness app, lol first thing I did was press 0%

I use data and get 5mA in standby (screen off).
If this was true, the 1230mAh battery should last 1230/5=246 hours in standby mode running Android, which is 10.25 days, right?
We all know this isn't true.
The battery consumption gadget is cute, but not precise

Agree, it is a good build too. Cyanogen makes thing so smooth. I recommended Shubcraft, just because i have no drawback to say about it, but fortunately there are other builds we can use.

Who's gonna leave there phone in standby for ten days to test it, infact who's gonna leave their hd2 in there pocket for 30minutes, fact is my data is on I've just been to my current widget log and for the last ten minutes (logging every 2mins) my usage was 4mA, 5mA, 3mA, 6mA, 4mA
So you tell me? Guess the current widget doesn't work
Is there any other battery widgets so I can run multiple ones and compare.results?
I left off charge last night for 8 hours while I slept and used 5% I think its pretty accurate reality.

I made a simplier calculation. I lost 1% per hour, so 4 days in standby. maybe a more rigorous way. Current widget is not always very precise, but it can help a lot to trace possible battery drains.

Yeah, that's more accurate. That's approximatively what I lose too. But it's definitely draining more than 5mA.
It's not THAT bad, but Windows Mobile is still way more energy efficient.
My guess is that there are some things that should be turned off but aren't, hardware wise, when the HD2 runs under Android.

That's not the point of this thread. I am pretty sure this it is useful to new users because wm and android are obviously different to manage. I want to bring something rational here, talking about screen consumption and memory management. Not about "something" we can't see but drains.
I saw several windows mobile threads concerning battery life frustrations too, so it would be more constructive to make some real battery tests between this two Os. For now, what some users complains are just "feelings" for me.

Hey, I didn't want to belittle your thread, the OP is definitely useful
My point was, right now even with all tweaks, the situation is not really satisfying, and hopefully soon we won't need any tweaking anymore because the developers will have perfected the HD2 port.

One thing that may help some people:
Make sure that your phone is using superuser permissions correctly. A while back on an earlier build I installed setcpu and autokiller. I thought they were working correctly but my battery life was poor. I tried opening superuser permissions and it crashed. I uninstalled Superuser Permissions, then reinstalled. Now setcpu and autokiller work correctly and battery is very good.
There is no indication that these apps aren't working besides the "... granted superuser permissions" popup. If you don't know to look for that message you may not realize there is a problem.

PS: Some of you might ask why Yin? This thing is fast! Active as a Yang! Because this is more or less a ROM which you will keep on your phone for a long time and therefore will give you the feeling of stability and calm.
Thanks to hardcore for the kernel and wifi drivers, camalot for the keyboard, boomboler for AppWidgetPicker, aleadam and F44g0r for the Armani hacked camera app. If I forgot someone, please let me know

Ugh, really?! I just flashed Continuum 1.2 lol. Guess I'll have to give this a try since you make the best ROMs.

How's battery life with Yin?? Does it have a stock kernel?
I will flash this and test

Keep Continuum if you use TiBu frequently. I got used to installing apps again from the market and inserting my credentials However, if you flash, leave it 10 minutes after the first welcome screen, turn it off and start it again to see how fast this damn thing boots. HTC's fastboot has now competition

do i9000 kernels work on this?...i just want to keep speedmod until a i9088 native kernel comes out that is as good...ill come over when the tibu issue is fixed

I must say that I was impressed by the battery life. I lost 40% in 16h with moderate usage = 8h standby - wifi on, sync on for 3 accouns (google, fb and twitter), tapatalk running in the background - messaging (i recieve 2 SMSs for each email i get), regularly checking mail and 1 call for 5 mins.

I was impressed with kp1 modem when using it before, up to 2600 kbps down and 1600 kbps up with ping times between 130-180 (never had that download speed with jk4, etc)... I'll post my results after, just charging to 100% and then its go time

Cezar,
Sorry to hear about the TiBU issues, I know you were working hard to fix that before release. Just wanted to thank you for releasing anyway, I enjoy your work.

I tried some possible fixes with Joël Bourquard, the TiBu dev, but none of them worked. It looks like a locale issue as TiBu is looking for EN locale but cannot find it (not sure why...) even though it exists. I am sure he is digging, hopefully will have a fix soon.

Cezar does your theme work on this rom?

Cool. Glad you got it going. Downloading now.

Android OS process eating away battery life

Hi all,
So, this problem appears common on other phones as well, and appears to be a Gingerbread issue. Drilling down further using Watchdog Lite on the phone, it appears to be a process called Suspend causing the high CPU usage.
There are a few threads on this:

http://code.google.com/p/android/issues/detail?id=15057

Personally, I'm getting pretty terrible battery life out of my S2, and I can confirm that in the Battery Status menu, Android OS appears extremely high at around 40% (a friends Nexus has this sitting at around 2%).
Not sure there's much we can do about it but wait and hope for a fix from Samsung (or Google)... People are reporting that rebooting the phone can help, but it's only temporary.
Anyway, just something to check if you're having issues.

+1 second that.
Android os eats the most of the battery
Reboot helps temporarily.

My os is at 79% i have no idea whats going on? but i am running launcher pro plus?

OK. So now we have identified an "issue".
Could you guys post juiceplotter logs while phone is asleep and draining, and while in use?
For asleep, i mean literally not touching it for half an hour. On, just occasional tap to keep screen on.
What we are after is an idea of what is causing system to use the power. Can we compare configurations of push email etc, to see if anything differs?
Are we rooted? Etc

Hi mate,
I rooted my phone yesterday, but I don't think that's a cause as it was just as bad before. In fact I rooted it just so I could freeze some apps
At the moment, I only have my google account set to sync (calendar, mail, contacts), and I have gmail pushing through emails.
All the stock Samsung apps are frozen. No widgets are running (I'm trying to run it fairly barebones to see how long I can get out of it).
I don't have juiceplotter installed, I'll look into that. I do have Watchdog though, and from all the other threads on this issue the problem seems to be the Suspend process (confirmed by a Google employee).
I don't think there's much we can do aside from wait for a fix. The problem appears to have been around since at least September last year.

I had this the first few days I had the phone, my battery was being wiped out in hours.
I formatted both my mem cards and hard reset. Since then my battey life has been amazing (got through the whole day yesterday only using 25% battery), and os use has dropped to about 18% (still a bit high but better than 40%).

Same issue here, both new flashed roms and my own slim roms suffer from same issue. I have a look tonight if i can find any solution.

I don't have juiceplotter installed, I'll look into that. I do have Watchdog though, and from all the other threads on this issue the problem seems to be the Suspend process (confirmed by a Google employee).
I don't think there's much we can do aside from wait for a fix. The problem appears to have been around since at least September last year.

OK. I will see if I can think of anything, as I remember we fixed a similar issue when popping 2.1 onto it, when some binary was giving us trouble...

Root or no root don not affect this issue. Only time i dont get it: fresh flash of new rom without anything installed.

Same issue here and I rooted freezing load of Apps but still drain
*edit*
It seems to stop drain when using reboot the phone.. not yet confirmed just a speculation... Btw these processes eat a lot of battery never got these problems on sgs1 custom gingers rom

Seem that ginger on SGS 2 has this bug present:
http://phandroid.com/2011/03/04/android-2-3-3-gingerbread-update-killing-nexus-one-battery-life/

Did anyone tried this? I had a similar issue with Gingerbread on SGS1 and it was fixed after clearing the data for System Update.

Haven't encountered the problem yet with pretty heavy use plus a few resets. It's probably a specific app or settings that you're turning on/using after each hard reset that causes it.
I'm still on the original firmware though, haven't flashed a new one yet. Might be related.

this is not universal, i don't have this problem. sgs 2 rooted with insecure kernel by chainfire.

*subscribing*
I also have the same drain issue. I have the S2 setup exactly the same way my Captivate was, and the battery life isn't the same.

I got better results after disabling background data in accounts ans sync (settings)
More testing ongoing.

Not really relevant I think - all Android users are going to have background data enabled in accounts and sync. Mine is enabled without the issue, anyway. I am only syncing a single gmail account though.
Have you tried what the linked thread recommends - going into manage applications and clearing data for the update system? You might want to try clearing data for all of the android system tasks.

Yes, but this 2.3.3 bug eat 5-10% battery/h in idle!... so all solutions is good.
I tried a number of "solutions", none helped. The background data seems to help

I just tried this, gonna charge to 100% then unplug it and let juiceplotter run to see what happens. Also I have the Samsung account app frozen.

Guide: De-Bloating and De-Touchwizzing the Note 5

I updated from the Oneplus One and Nexus 6 to the Galaxy Note 5 on T mobile. I wanted a better camera, better screen and better hardware. The note 5 delivers on those things and then some. But coming from the OPO and Nexus 6, I was really missing stock android and material design, and I was used to customizing and streamlining the apps and features to maximize performance and battery life. I had an idea what I was getting into but Touchwiz and all the bloat had to go! You can disable much of the bloatware, but many apps I dont need or want are built into the system and cant be disabled in the App manager settings. Since we dont have root yet, and Im new to Samsung phones, I did some research and I wanted to provide some of things that helped turn the note 5 into the kind of phone I really love now. Please suggest anything else you have found that helps.
First thing I noticed was the cell standby battery drain which I have seen on numerous lollipop devices and roms. It was draining the hell out of my battery but I found out it was an easy fix on T mobile. Disable Voice over LTE by going to dialer app --> More --> Settings --> Voice over LTE settings --> Do not use. No more cell standby battery drain!
Apps:
Adguard- Im used to using an adblocker app but most of those require root. Adguard creates a VPN on the phone and filters out all of the ads from web pages and tracking info from your web data. Speeds up any browser and helps battery life.
Package Disabler Pro- Usually disable or uninstall unwanted apps with Titanium backup, but this app can do those same functions without root! I disabled 178 system apps and bloatware. Phone performs better and battery life is amazing (On pace for SOT of 9-10 hours with brightness on auto, battery saving location settings - wifi and cellular only - when Im not at work where I have really crappy signal all day. I will give a full battery life test this weekend).
Next thing was getting as close to the stock look and feel as possible. I got the Dark Material Theme from the Theme store before disabling the Theme store . I installed Action Launcher but Nova Launcher will serve the same purpose, and disabled the Samsung Home Launcher. Unfortunately when you switch the launcher, you go back to those cartoony Samsung icons. No good. So I installed Glim icons There are many material design icon packs and the icons here arent strictly like the stock ones but they are very nice and the nice thing is it changes out most of the Samsung icons for the apps you will want to keep around, like S note and the Galaxy Apps (I bought the paid version which I think has more icons). Now the software looks amazing to go along with the hardware. And I was concerned about battery life coming to this phone but now, to my surprise, battery life is actually better than I was getting on my Oneplus One on Lollipoop. May not need root after all.
WARNING: DO NOT USE ULTRA POWER SAVING MODE IF YOU HAVE COM.SEC.ANDROID.EMERGENCYLAUNCHER DISABLED - YOUR PHONE MAY FREEZE AND BE UNABLE TO BOOT AND YOU WILL HAVE TO DO A FACTORY RESET. THE REGULAR POWER SAVING MODE IS OK.
I attached some example xml files. There is a "basic" xml file with around 150 disabled apps where I only disabled the apps I am sure of what they do, and mostly left apps and services that shouldnt run in the background most of the time anyway. This package preserves the most functionality and gets rid of the samsung fluff that you probably dont want and gets rid of most of the things they use to spy on you.
There is also an "extreme" version which I would say is still somewhat experimental but has been running great for me so far. BUT USE AT YOUR OWN RISK IT MAY NOT BE COMPATIBLE WITH ALL APPS AND SETUPS. It disables around 200 apps!!! I attached screenshot of battery life I have gotten with this configuration. This is my own personal configuration so there is some minor functionality missing because I only left the things I felt were important for how I use the phone. If you like, you can import this and work backwards, enabling the things you want if you kind of know your way around the app.
I also am posting a screenshot of the 250 apps and services you can disable safely without crashing your phone or creating major issues. Probably. Hopefully.
HOW TO USE XML FILE: You have to download and unzip the xml file, put it in the /storage/emulated/0 section, open the app and select import xml file from menu. You will need to re-enable the stock LAUNCHER, CLOCK, CALENDAR, MESSAGING APP AND KEYBOARD, or replace with alternatives from playstore like I did if you use extreme configuration. You will also likely get a message saying you have modified your phone without permission or something when you try to do a System Update (at least thats what I get on the T mobile version). When there is an update or you want to check, you should use the app to export your file to preserve your settings, then re-enable everything, reboot the phone, check for update, then import your xml file again to go back to how you want it.
To update if you're coming from a previous configuration, first go into menu and enable all disabled apps then import the new XML file.

Without the volte enabled does that mean the calls won't have the little HD when calling another tmobile user?
Sent from my SM-N920T using Tapatalk

Probably. This is the first time I have had the option for voice over LTE on my phone so Im sure i wont miss what I never had. Im sure someone else here knows better than me, but I think HD voice is linked to Voice over LTE? The cell battery drain is a bug so if you dont have it, leave voice over lte enabled. Hopefully it gets fixed soon.

it is, HD voice is VoLTE. And i agree about the drain. I talk on the phone so little i dont really care how clear it is as long as we can hear each other. The future of coice calls is VoLTE so hopefully it will be fixed before that

I'm on the AT&T variant and am interested in the steps you mentioned. I guess maybe a bit of research will be required but do we know if TMO and AT&T share all of the same files or does one require more than the other. I am interested in getting your XML file but minus the TMO stuff.

I actually just finished disabling everything manually with your list vs TMo/AT&T.. there are a small number of differences but most of your disabled services are full on android vs carrier specific (stating the obvious)
So far, so good, I'll be able to tell more after I do a full recharge on battery, now just waiting for it to dwindle down by the end of the day.

Just debloated mine this is usually first thing i do with root. Great find

Thanks for your guide and the tips on Debloating - I usually use Titanium Backup - but can't for obvious reasons (yet) so this was a very welcome thread. The Ad blocker is also very good and works well -
Thanks for the tips - I haven't 'frozen" all of the apks that you did - but I did freeze the ones I don't use or want - and now I will run for a few days to see what sort of impact it has on battery - thanks again -

EDIT: not ready for prime time. Got stuck in boot loop. Stick with earlier version.
The new update for package disabler pro allows you to easily Google different apps to see which are safe to disable. Took some time doing this especially comparing some of the other Samsung scripts out there and disabled another 20 apps or so. Here is battery life from first 20% lost just while researching and the list from xml file. Not much idle time but so far so good, but I'll check for issues and adjust if needed.

[BATTERY] life got you down? Here's how I fixed mine!

Everyone talks about the incredible battery life on the OP3T. I had some good battery life in the first couple weeks of having the phone, then it seemed like it had gotten worse around the time I installed 3.5.4, then continued when OOS4 hit. Friends of mine with the OP3T however, didn't have the same problem. I was essentially having constant drain to the point where my phone, whether the screen was on or off, dozing or not, would drain approx 2% per hour at baseline. Far worse than it should. Even more frustrating, the standard android battery page in settings showed me that my phone was being used most by Android System and Android OS (not even play services!). Here are some screenshots of my battery life and some stats:
{

"lightbox_next": "Next",

Being the standard XDA user, I decided to figure out what the hell was going on with my phone, so I installed the usual apps. My go to battery stat apps are: wakelock detector, betterbatterystats and gsam battery. These apps are fantastic for determining what is killing your battery, usually in the form of wakelocks. There is an incredibly helpful guide to understanding wakelocks here. These apps in my past experience had all required root to my knowledge, but I gave them a shot anyways. Since I am on stock OOS 4.0.1 without root or TWRP, I found that I was able to grant the necessary permissions by using adb commands to grant battery stats to each app despite not being rooted.
Code:
adb -d shell pm grant com.gsamlabs.bbm android.permission.BATTERY_STATS
adb shell pm grant com.uzumapps.wakelockdetector.noroot android.permission.BATTERY_STATS
adb shell pm grant com.asksven.betterbatterystats android.permission.BATTERY_STATS
I then spent about a week obsessing over my battery life and literally checked these apps, especially GSam's "Rate of Change" (always showed AT LEAST 2-5% drop per hour, at MINIMUM) and "Other" graphs to try to figure out if my phone was sleeping properly, etc when I changed settings. Android OS and kernel were both at the top of the multiple lists of apps using data in GSam and BBS, but when I would click on each process, it wouldn't actually tell me what was driving their high utilization. I looked through these two processes and noticed for example that NLP was high so I disabled location on all apps except google now. I even disabled location services completely (with no subsequent change in battery life). What was frustrating to me, though, was that my battery wasn't draining due to wakelocks. The wakelocks I had were appropriate. Google now set off thousands of alarms (*alarm*), but this didn't seem to be the reason for my battery drain. I also changed pretty much any setting with anything to do with battery life, hoping that it would fix my issue, ie disabling pocket mode, disabling ambient display, disabling google backup, setting my exchange email account to poll every 60 mins instead of push email, removing extra apps, uninstalling screen filter apps (ie lux dash, twilight), using greenify, turning on aggressive doze mode, etc. Ultimately, I performed a factory reset because I thought maybe the upgrades from 3.5.3 to 4.0.1 caused some trouble. I only installed the essential apps I would use every day, but soon after realized that my battery life was unchanged after the reset.
Then yesterday, I came across something about apps utilizing more CPU time, etc. GSam and these apps list the stats for CPU time by app, but my interest was piqued. I opened GSam and looked at the CPU usage graph and realized that my CPU was constantly being utilized and wasn't coming down to 307 mhz very often. I installed a couple random CPU apps from the play store but nothing gave me the information I was looking for. They just confirmed what I noticed in GSam, that my CPU was never really off. Next, I figured hey, I do it on Windows, why don't I try to use ADB to look at my CPU usage real time by app/process. A quick google search and some futzing around and I was in business with the following ADB command (NB: hit ctrl+c to exit out of the loop):
Code:
adb shell top -m 20 -d 2
This command brought up the top 20 processes using my CPU and would refresh every 2-3 seconds as long as the command was still running. When I would shut my phone off and let it "idle", I found the two unsuspected culprit applications that were CONSISTENTLY eating up 2% and 1% of my CPU: textra(see 4/30 update below) and swiftkey. I uninstalled textra and switched to google messenger. I tried switching my default keyboard to google keyboard, but had the same issue, so ultimately had to disable swiftkey (can't uninstall it without root as it's a system app). After that, I was in business. My phone went from 2+% drain per hour while idle/dozing to 0.7%/hr (according to gsam). Overnight, I only lost 2% battery over 5 hours while I was sleeping. This used to be at least 6-7% before. I'm almost at 24 hours since discovering this, and my battery life is MUCH better even with heavy use.
Thanks for reading, hopefully this is helpful to others in tracking down some rogue or crazy app that is driving you crazy. Cheers!
Edit 1/12, full day 2: battery life went crappy on me again. Looks like inbox was the culprit this time, consistently in the top 3-5 processes. Wiping data seems to have fixed it for now (not sure what changed, wiped cache first and closed out of inbox properly prior to wiping data).
Edit 4/14: gboard keyboard began doing the same thing for me last month that swiftkey used to do. Went back to swiftkey and seems the issue is resolved and swiftkey no longer drains better like crazy.
Update 4/30
nhshah7 said:
So 4/30 update on my battery life. I thought swiftkey was fine for a couple weeks especially since I had syncing off (I thought this was possibly the culprit but I was wrong), but then last week I checked again and swiftkey was running near the top of my list of processes (again) and my battery life was starting to suck again. I disabled swiftkey and reverted back to the stock google keyboard apk (NOT gboard) for a while with an improvement in my battery life. I wanted the gif feature and the backspace/delete feature back so I updated to the most recent gboard and my CPU usage jumps from 3-5% according to GSam to 8-9%. I run the top command again and lo and behold, it's at the top of the list again (see image below).

I then uninstalled gboard updates (app info --> gboard --> menu --> uninstall updates) and reinstalled version 6.2.18.151907649 and I THINK that this version doesn't kill the CPU (not in the top 20 while idle at least). Didn't try any other versions though. If you do this, be sure to disable auto-updates from the play store for gboard!!
Also, I'm curious why no one has reported on this being a major issue. Is this just a bug on oxygen OS, android 7, swiftkey or gboard? Does this happen on all phones? If it's just on oxygen OS, oneplus has some work to do!
Just some investigation on the side, I powered up my trusty oneplus one which was running slim6 and ran the top command. It's syncing a bunch since I haven't turned it on in a few weeks but I don't see swiftkey (updated to the latest app version) in the top 20 at all! And on top of that, textra was nowhere to be found on the list either (granted there's no SIM in the phone)! NB: just for fun, I reinstalled textra lol and it didn't show up in my top 20 list. hopefully it stays this way!
I've been stock unrooted for a while now, but if this crap keeps up, I may have to root so I can try a different kernel or disable permissions for apps to wake the phone up grrr.

Update 5/24:
Googlequicksearchbox alarms were driving me nuts, with thousands of alarms resulting in HOURS of kernel wakelocks. I realized this had only been going on since I upgraded to OOS 4.1.3. My work-around was initially to disable the google now feed but apparently removing the google now widget from the home screen (regardless of whether on nova, OP launcher or google now launcher) stops the alarms and significantly improves battery life. Wow.

Nice! So generally it would better to find out what is constantly using the CPU on a case-to-case basis, but going from your final results: SwiftKey and Textra were the culprits. I was reading the other thread about SoT and people were getting over 6+ hours and I was getting only.. 3-4 at most? I've had the same issue as you where the battery was draining and I could not really find the source (general suspicions such as G Services didn't really contribute).
Thanks for letting us all know! I'm running OOS 4.0.1 (fully stock, unrooted) and I've just uninstalled/disabled SwiftKey (didn't realise it came stock). Will see how it is in a few days..

Yup, I was getting 3-4 as well before I fixed this.

I was trying this out because I am in the same boat. The command is wrong though, it doesn't take an option "-s".
I am kind of stuck at this point, the entries keep on jumping all over the place and the package names are being cut off (I see com.google.android.g and have no clue what's coming after the g)

the -s command worked for me. See attachment. Though I think it may sort by CPU activity by default anyways. Not sure why it's cut off for you but it could be gms or gms persistent (don't think that's anything to worry about). Try to leave your phone with the screen off and idling for a while to see if you notice any patterns if you haven't already.

Nice find. Really useful to the community. I had swiftkey disabled day 1 because did not like the layout. Battery is doing ok. But how do I go about uninstalling swiftkey entirely?

Unfortunately you can't if you are not rooted. Just disabling it is fine though. I'll clarify that in my post, I think I wrote it out wrong initially.

Man I'm a huge textra user and I really love their app, maybe we should let them know about this so that they can improve their app ?

i just finish uninstalling my swftkey...will share results soon

Well I also use Textra and my OP3T has no battery drain issues, but nonetheless thanks for sharing. I get about 6-8 hours of SOT regularly with both Oxygen OS 3.5.3. and Oxygen OS 4.0.1., so I guess its depends case by case. Swiftkey is uninstalled through Titanium Backup, since I use Gboard.

The 2 apps that used the most CPU on my phone were Genius and OnePlus Launcher. I removed genius and installed nova launcher. Battery is much better now

Thanks a lot for this! I have had mediocre battery life on OOS 3.5.3, then very good battery life on OOS 3.5.4, but unfortunately again mediocre battery life on OOS 4.0 and 4.01.
The difference in BetterBatteryStats was that awake time fraction was around 15-20% for mediocre battery life and well less than 10% for good battery life. I was not able to really find the culprit with BetterBatteryStats, but deactivated SwiftKey half an hour ago and it seems I am back to good battery life with less than 10% awake fraction. I think your method might be an extremely useful way to identify problematic apps.
By the way, another problem that appeared with the update to OOS 4.0 was that K-9 mail stopped synchronizing push messages and at the same time produced much increased wakelocks. What helped here (although it seems counterintuitive) was to switch on the "strict power management" feature in the battry settings and exclude K-9 mail from being optimized.

Interesting. I'm curious to see if it's using up as much CPU on your phone as it did on mine.

holy moly, I am a big fan of swiftkey from day1 and I have good battery life but not like the poeple here... I hope swiftkey will fix it soon. Maybe I can try to switching it to agressive doze so it will kill swiftkey process? Actually should it be killed anyhow if we are not using it?

90 minutes after disabling SwiftKey I can definitely confirm that battery life has improved a lot!

For me it's com.google.android.gm (corresponding to gmail I believe) it could be the same for him. I'll try to hibernate both swiftkey and gmail with Greenify
Thanks for the tips !

I ran the command and it gave me error that it cant open proc/stat
"Cannot open /proc/stat"

Given that the OP has identified Swiftkey as a decent battery drainer (I am going to try this simply to see if I can squeeze any more battery out of what I feel is an already impressive performance), is there any keyboard anyone would recommend? Swype?

one from google is not that bad actually, they improved

Started to use it but it doesn't show the word you're typing, using swipe, in certain apps such as, ironically, Google browser. Any other suggestions from the forum
