I see lots of posts around the Interwebs complaining about battery life on smartphones (specifically Android ones, since I don't hang out on sites that are aligned with evil Apple), so I decided to consolidate my knowledge for people with Slide's to improve their battery life.
DISPLAY
This uses about 80% of the power according to battery use on auto-brightness. On a bright day I can read the screen at about 1/5 position on the brightness bar which cuts down heavily on the battery use.
There's not much else we can do to cut down on screen power usage, so moving on.
CPU
This one requires SetCPU, I strongly urge you to buy it from the Market (it's just a few bucks IIRC) and supports the AWESOME dev. If you're cheap just go download it from that link.
Once you have it you'll want to set up profiles! So click profiles, check the box next to the Sleep profile and choose 480,000/480,000 with ondemand scaler! I have no idea if it actually changes anything but the placebo effect is nice. Next back out of that and set the CPU governor to performance. What this does is clock the CPU to 600mhz constantly instead of scaling between 480mhz and 600mhz as the additional power is needed. It cuts down on choppiness while barely increasing the amount of battery required (in my experience the Slide tends to jump up to 600mhz when I'm not doing anything anyway).
Sync
Turn auto-sync off or set the sync intervals to the highest number possible (once a day I believe). It takes power and most of the time doesn't download anything important. If you really need some data just go and hit Sync Now and, well, it syncs.
Autostarts
There is this nifty little paid application in the market (costs like $1.25 or something) that you absolutely need: Autostarts
Basically applications launch when triggers are triggered, alot of these are pointless and just take up RAM and power.
These are what I have disabled:
After Startup
{Any 3rd party apps that aren't widgets}
Calendar Storage
Download Manager
Voice Dialer (unless you, yaknow, use it)
Maps
Mail
Calendar
HTC Media Uploader
My Account (unless you like the power alerts that take up power!)
Connectivity Changed
Download Manager
My Uploads
HTC Media Uploader
Genius Button
Media Mounted
My Uploads
Application Installed
Voice Dialer (wtf?)
Pico TTS (sem-wtf?)
Application Removed
Voice Dialer
Application Replaced
Maps (lolwut?)
Autokiller
There's an app called Autokiller, it changes the internal task killer's settings as to when to tell an app to shutdown (at stock settings this is almost never).
I use the moderate preset, but you may want to increase it if you never want to have to manually kill a task. Note that this method tells apps to cleanly shut down so data is saved (such as the page you are on in the Browser)
Additional Settings
In Mobile Networks set to GSM only (no 3G)
Turn GPS and WiFi off when not in use
Turn always on data off
Use a silent or vibrate alert method instead of sound alerts
Turn off your screen whenever you can
If you flashed ENG-BUILD flash the updated RADIO!!!!!!!
Protips
Do several battery cycles every 6 weeks (Charge to 100%, discharge to 0%, charge 2 hours past green LED while phone is off)
Espresso is heavy duty stuff, use a non-sense ROM for additional speed
Charging via USB takes significantly longer than charging via AV
Live Wallpapers will use lots of battery
Use wallpapers formatted at 480x320
Limit the amount of widgets you have to around 5 (unless they are from the same app, like Beautiful Widgets) they constantly refresh and do their thing in the background
I learned most of this thanks to enatefox's guide which I modified to suit the Slide, a coffee fueled mind, and general observations. If you have anything to contribute please let me know and I'll add it!
check general, few threads there on this .. it seems the development section is the hot spot around here..
an APN widget will do wonders, or even juicedefender.
i disable APN until I need it. screen is about 30% always. after everything i do i lock the screen.
on a normal days use (1-2hr phone calls, 30-50min of browsing the net, a ton of text messaging, and streaming slingbox) I'll have about 60% battery by 10pm.
great guide. thank you.
does autostart continually kill those processes? I ask because that long list of bloatware you listed is what is irritating me on my slide and even when I force kill them all they restart themselves every 5 minutes. I have taskilller set to kill them and they come back like the herp constantly.

Autostarts does not 'kill' processes, it disables them from running when certain triggers are triggered.
For example if SpywareApplicationOVER9000 runs everytime an application is installed, and you disable it in Autostarts, then it will not run when an application is uninstalled

Better Battery Life Tips
I've been using (and tweaking) Android devices since the original HTC Dream (aka G1, Android Dev Phone) was released, and I've had devices that are both good and bad at power consumption. In this thread I will share what I have learned and invite you to share what you have learned as well so that we can all get the most out of our devices.
Please note that I like to keep my smartphones "smart" and don't like to be manually toggling things on and off throughout the day. If you like to geek out 24x7 you can manually turn on/off every feature of your phone every time you use it to conserve juice... that's not me though!
Here we go...
-Consider a Different Browser
It seems like Opera Mobile and Mini are the kings of battery conservation. I tried Dolphin, Boat, Firefox, Chrome, the stock browser, and about 10 others... I didn't see significant differences in battery with any of them, but with Opera I noticed the difference. It makes sense since Opera renders the pages and optimizes the images remotely and then sends the bare minimum amount of data to your device to display the page.
-Location, Location, Location
Android's location related services can be a big drain. There are 3 different location settings you need to know about.
1) Location Access (Settings -> Location access): For maximum savings, you can turn off "Access to my location". However, there are many apps that make good use of your location. If you don't want to cripple them, leave this option turned on but at the very least uncheck "GPS Satellites" to save some juice.
2) Google Apps Location Settings (Settings -> Accounts:Google -> Location settings): Allows Google apps, such as Google Maps, to access your location. Why this needs to be separate from #1 above is beyond me, but turning it on requires the above setting to be on as well. If you don't use Google Maps, Now, Plus, or any other Google services that use your location you can turn this off.
3) Location Reporting aka Latitude (Settings -> Accounts:Google -> Maps & Latitude -> Location Reporting): This is the bad one. Really bad. Wakelock and battery drain city. I don't even know why anybody would want this. Kill it with fire. Set it so that it does not update or report your location.
-Turn off stuff you don't use
This should be common knowledge by now... if you aren't using GPS, Bluetooth, or even 4G... turn them off. If you don't need instant notifications and app updates you can even turn off Auto-Sync. If you decide to do that, I recommend the Synker widget from the Play Store. It is nice and configurable so that you can sync on demand with one touch.
-ROMs and Kernels
I'm not going to go into these too much here... there's a whole development section devoted to them with tons of info. Generally you get the best life from the stock based ROMs. Liquid Nitro and HO!NO!'s v20f (+Wind kernel) are quite good. Next best is probably HO!NO!'s CM9. The CM10.1 ROMS and kernels have a bit of catching up to do at battery consumption, but they keep getting better.
-Kill Google Talk!
If you don't use this program, disable it. It is always trying to do something on the network. Even if you turn off data and wifi you can still get NetworkConnectivity wakelocks from this app trying to do its business! Killing it is the first thing I do after flashing a ROM, especially CM10.1. From home hit: Menu -> Manage Apps -> All -> Talk -> Disable.
*Some report that disabling apps through the Android OS might not stick. If this is a concern for you, download NoBloat or Titanium Backup and freeze this app. Or if you're a nerd like me, use a root file explorer and move or rename the .apk file in /system/app
-Kill Google+ (Plus)
Just like the above, if you don't use it, deactivate it. It also uses data and location services pretty regularly. Disable it in the same way, or use NoBloat or Titanium.
-Kill Google Now
If you don't use it, deactivate it. It uses data and location services pretty regularly. I like its features and keep it enabled on my N7, but leave it off on my phone. To turn it off, go into the Google Search app (long-touch menu/search button), hit Menu -> Settings -> Google Now. You'll see the option to disable it.
-Data-Toggling Battery Saver Apps
These are pretty controversial, almost as much as app-killers were when they were very popular. In a nutshell they turn your data connections on or off based on whether your screen is on or off. They usually will check to see if you are downloading or streaming anything before they shut off the connection. Then, they periodically turn the connection on while the screen is off so that the device can perform a sync to get emails, etc.
Should you use one? If you are running CM10/10.1/AOKP4x then YES USE ONE!! EDIT: THE LATEST VERSIONS OF QUATTRIMUS AND WIND FOR CM10.1 HAVE RESOLVED THE BATTERY DRAIN ISSUE. Use of a battery saver is no longer essential. If you still want to use one, read on...
Whether or not you use a battery saver depends on how you use your phone, and if you are willing to accept the trade-offs. These apps get their savings from maximizing deep sleep time for extended periods with zero data concerns or interruptions. If your usage habits allow the app to do its job, use it. If not, don't use it.
[What follows here is some long drawn out jibber jabber about the pros/cons of these apps. Read it if you like]
Some people love these battery saver apps and swear by them; others hate them. The reason some like them is because they get a few more hours of battery life. The reason why some people hate them is because:
1) They wake the device periodically to do their job... which negates some of the power savings you get from having them. To some people these tiny wakelocks are the most horrible thing ever... even if their impact is quite small compared to the power being saved. These people are usually the ones who live and die by their BBS logs. I'll admit, I was one of those people
2) Syncs are delayed, so messages and notifications do not arrive instantly but when either of the following conditions are met-
a) The screen gets turned on (which triggers data on and autosync)
b) The program hits a scheduled time trigger (usually at user selectable intervals)
3) There's a small lag while data connects when the screen gets turned on. If the screen gets turned on very frequently the constant on/off/syncing can actually hurt the battery more than it helps.
But, if you are ok with the delayed syncs and you set up the sync intervals long enough apart you WILL see a gain in battery life. Your phone will sleep much more soundly as well. With one of these apps my Nitro HD on CM10.1 can sleep all night and will only lose maybe a percent or two.
*Note that these will NOT help you at all when the screen is on, which is a bummer because the Nitro screen sucks down a LOT of power. Also, your usage patterns may make them ineffective for you... in which case you are probably better off without them.
Personally I get about an hour or 2 of extra life if I use one, but it's a trade-off since I lose instant notifications and a there's a slight delay while it reconnects to the network when the screen gets turned on. And the more you turn your screen on/off, the more it disconnects/reconnects/syncs... meaning it is using a bit MORE power than usual for those seconds.
[/jibberjabber]
The following are my favorite data-toggling battery-saver apps. All of them have "free" versions and more advanced "pro/prime/advanced/whatever" paid-for versions. These are not the only ones out there; feel free to report back on ones you prefer. If you find one that you really like, I suggest buying the pro version not only for the additional customization they offer, but to support the devs for a job well done.
1) DS Battery Saver - Super easy to configure and since it kills background tasks before sleeping it puts your device into a nice deep sleep. Also combines the feature of CPU Sleeper if you are rooted... it'll shut off a CPU core when sleeping.
2) Green Power - Works really well. The interface is simple and well laid out. I used it for years before I discovered DSBS.
3) Juice Defender - Another decent app, similar to Green Power. I personally preferred the options and the interface of GP better, but you may not.
4) CleverConnectivity +++Battery - The interface is a bit weak, and I had problems with the full data on/off features working on my P930 w/CM10.1... BUT this program has one very cool feature- it has an option for dropping the connection speed down to 2G/EDGE when the screen is off instead of disabling it completely. This allows syncs to still occur while still saving some power in 2G. I've even streamed Pandora on 2G, so in theory you could do stuff like that too. This feature worked fine on my P930 dispite the normal data on/off failing intermittently. There is a moment of zero data while it toggles between 2G/3G. I think this app might be awesome when development advances some more.
-Underclocking (rooted users)
Capping your max CPU frequency at a lower limit can save power. Quite honestly, for 99% of my daily use I can't tell the difference between the CPU clocked at 1.2ghz and 1.8ghz except that at 1.8ghz my battery bar laughs at me and gives me a wedgie. On custom ROMs there is often a built-in method to set the CPU clock frequency (Settings -> Performance -> Processor). On stock-based ROMs you'll need a 3rd party app like Kernel Tuner, SetCPU, or any of the other 50 options in the Play Store. You can usually safely set your minimum frequency to 192mhz, but some phone/ROM/kernel/voltage combos will cause stability or lag issues with doing this. YMMV.
*If you are using a CPU controlling app like SetCPU that allows for profiles, you might be tempted to set the screen-off frequencies to the absolute lowest setting of 192/192... be careful! This setting could end up costing more power consumption because the CPU has to work for a much longer time to handle the tasks at hand at such a low clock speed. If it was allowed to ramp up a bit the task would be done more quickly and efficiently. Honestly I gave up on setting screen-off profiles. I just use governors based on smartass which have their own screen-off settings integrated. Less adjustments needed, similar results. This leads us to...
-Changing governors (rooted users with custom kernel)
There's about 50 different governors floating around out there. If you don't know what a governor is or what each one does, read this thread: http://forum.xda-developers.com/showthread.php?t=1736168
In short: Any governor that is based on smartass, ondemand or interactive is going to be pretty light on battery, and you may not be able to tell the difference between them in normal use. I like smartassv2 and badass, which are both based on smartass. Conservative may sound the most battery friendly, but usually ondemand does better and is less laggy.
Try some out. Have fun with it. Eventually you'll want to start tinkering with the I/O Scheduler... that's a topic for another thread. There's not much battery life to be gained there anyway.
-Undervolting (rooted users with custom kernel)
WARNING: This can cause instability if done improperly. MAKE A CWM BACKUP BEFORE TINKERING WITH UNDERVOLTING!!! I've never seen *drastic* gains on any device, but you do get a little bit more life, and every little bit helps, right?
So if you want to do it, read this: http://bigfatreality.blogspot.com/2012/03/guide-to-undervolt-android-safely.html and then proceed with caution.
Generally you can aggressively undervolt at lower frequencies, but be careful at higher frequencies because your device needs more power under load and will not like it if it can't get it. If you're a car guy this is like running too lean of a fuel mixture
Kernel Tuner and IncrediControl have nice GUIs for fiddling with voltages. Remember, adjust in tiny increments, followed by thorough testing! If you get a crash or reboot then you've gone too far. DO NOT ENABLE "SET ON BOOT" UNTIL YOU ARE SURE YOU'VE GOT STABLE VOLTAGES!!!
-Screen dimming
Screen backlights use lots of power. This ain't no AMOLED where you can save power by using dark backgrounds- LCDs light up the entire display regardless of what is on them.
I suggest turning off auto-adjust and set your brightness at a level that is just bright enough to be comfortable. I keep mind around 30-40%. Auto-adjust periodically polls the sensor to get light data, and uses a small bit of power to do it each time.
Turn on the 'Status Bar Brightness Control' if your ROM supports it so that you can easily swipe your finger along the top of the screen to brighten or dim the display on the fly. In CM9/10(.1) this option is under Menu -> Settings -> System -> Status Bar -> Brightness Control.
If you MUST use the auto-adjust, consider adjusting the levels that it uses. Make them as dim as is comfortable for you. For stock-based ROMs you'll need a third party app like this: https://play.google.com/store/apps/...wsMSwyLDEsImNvbS52aXRvY2Fzc2lzaS5sdXhsaXRlIl0.
For CM/AOKP based ROMs this can be done from the Display -> Brightness sub-menu of your device's settings area. CM10.1 has an excellent and simple adjustment interface.
-Build.prop Tweaks (rooted users)
You can add the tweaks below into your build.prop file that may or may not help with battery life. Download BuildProp Editor from the Play Store and add them. They seem to help a bit, but it could be placebo effect. They certainly don't hurt anything so give them a shot and report back what you get. These seem to work with ICS and JB:
ro.config.hw_fast_dormancy=1
ro.ril.fast.dormancy.rule=0
ro.ril.disable.power.collapse=1
pm.sleep_mode=1
wifi.supplicant_scan_interval=180
net.tcp.buffersize.default=4096,87380,256960,4096,16384,256960
net.tcp.buffersize.wifi=4096,87380,256960,4096,16384,256960
net.tcp.buffersize.umts=4096,87380,256960,4096,16384,256960
net.tcp.buffersize.gprs=4096,87380,256960,4096,16384,256960
net.tcp.buffersize.edge=4096,87380,256960,4096,16384,256960
^ this forum keeps adding a space near the 16384... there shouldn't be any spaces. I think they get disregarded anyway if they are put in the file, so no biggy.
^some of these have presets in BuildProp Editor, some you have to enter yourself. I copy/paste them individually. Don't paste the "=" signs though. Everything before the "=" goes under "Property Name", everything after it goes under "Property Value". If you are experienced you can edit the build.prop file directly using a text editor. Just back it up first and don't screw with the permissions.
-Some other useful apps that help with battery life:
*CPU Sleeper (root users)- Shuts off all but one cpu core when the screen is off. This probably isn't required with a good kernel and governor setup (and a stable phone that sleeps well), and if you are running DS Battery Saver this feature is built-in to it. It uses barely any resources whatsoever, so give it a shot.
*Greenify (root users)- This essentially freezes selected apps when they are not in use. They cannot do background tasks or wake your phone when they are not active. When you attempt to open one of the apps it instantly thaws them for use. After you are done with them it freezes them back up. It is quite brilliant really! It eliminates a lot of wakelocks and battery drain from apps trying to update, gather location data, etc. Use with caution though- don't greenify apps that you actually need to have a data flow from or ones that you use widgets for.
*RootDim (root users) - You know how when you are using your phone in bed at night and the screen is just too bright, even on the dimmest setting? This app lets you go even dimmer. Less brightness means less power, so it will reduce battery usage in the process.
-Apps that help diagnose battery drains
*Better Battery Stats - Good for discovering the cause of battery-draining wakelocks. Just uninstall it when you're done using it to diagnose- otherwise it is constantly doing its thing which is not going to help battery life any!
*OS Monitor - See if your CPU is settling down like it should and see what is keeping it busy. It also has a ton of other advanced options and features.
...there's too many apps to list here! Share the ones you like I'll add more later.
-Adjust your advanced Wifi settings
Go to Settings -> Wifi, then hit Menu -> Advanced
Most people agree that Network Notification should be UNCHECKED, Keep WiFi during sleep should be 'Always', and 'Avoid poor connections' and 'WiFi optimization' should be CHECKED.
If you have a noisy wifi router (some Netgears are guilty) that keeps waking your device from sleep with wifi packets you may get better results if you change Wifi During Sleep to 'Never' or 'Only when plugged in'.
-Watch the reboots!
Every time your phone reboots, Android checks the SD card for errors and then runs the Media Scanner to take inventory of all media files. Both processes consume power, so try to limit unplugged reboots. The more files on your SD card, the longer Media Scanner has to work, so get rid of unnecessary files cluttering up your card. You may have some luck using .nomedia files to tag directories to be skipped during scanning. You can also use an app like this to disable the automatic Media Scanning Service. It also lets you scan on demand. Caution- If you don't ever do a scan, then new pictures won't appear in your gallery nor will new music appear in your player.
I'm sure I'll think of some things later that I have forgotten, and I'll discover new things... I'll update this when I do.
Please share your findings so that this can be the best battery saving thread... In the world.
Very interesting and helpful info.
Thank you very much !!! :good::good::good:
Couple things I'd add, especially if you're running a CM-based ROM
Get NoBloat and disable the following:
SuperUser - Get SuperSU instead, less battery drain.
CM Update Checker - Every time I use my phone to go online (I don't have data on 24/7) this thing pops up and wants to check for updates, but never properly gets flushed. Disabling this one app dropped my hourly drain by about 1.5% on CM10

Thanks for this- I just disabled CM Updater.
BTW with JB there's no need to download NoBloat- you can disable most apps (including this one) from the built-in App manager. Settings -> Apps -> All -> CM Updater -> Disable
Here's another trick for a specific type of battery drain: (you don't apply the fix in on your phone though)
Symptoms:
1) Your phone drains its battery while doing basically nothing while connected to your wifi router.
2) BBS shows massive amounts of wlan_rx_wake wakelocks
3) Android OS seems to be a high contributor to battery use
Fix #1: (Found HERE) "Change DTIM value in your router configuration from 1 (default) to 255. This value is usually in Advanced->Wireless tab on most routers."
^Seems to help a lot.
Fix #2: Set a static IP on your phone for your home network. The easiest way to do this is to find out what address range your router uses when it hands out IP address via DHCP, then hard-set an IP on your phone that is not in that range so that there won't be any conflicts with other devices that connect to your network. You'll need to consult your internets and googles to figure out how to get this information from your router, if you don't know how. Once you know a clear address you can use, go into your phones Wifi Settings, long-touch your network name, hit 'Modify', 'Advanced', punch in the static IP you wish to use. This might not be an option on corporate or shared housing wireless routers.
Fix #3: Check ALL computers on your network for the presence of the Dropbox software. Mac, Windows and Linux computers alike. If it is running in the system tray, click it, go into preferences, turn off 'LAN Sync'. This little booger wreaks havoc with wifi locks on some Android devices.

I've found that for whatever reason the built-in app disabler doesn't always work. I still like using NoBloat better.
Second to this, once you do disable a bunch of apps it's good to boot back in to recovery and wipe dalvik/fix permissions.

Oh this is kinda off-topic but Mattman86 I wanted to ask you, I just installed your Hono CM9 Full Throttle rom and I'm having some issues putting the apps onto my SD-Card. Whenever I move them (through titanium backup or just standard move to sd in settings) whenever my phone restarts the apps disappear and or say "app not installed" then they are a green default android icon and just don't work :\ Also does Wind Kernal work with your 4.0.4 Rom?

I haven't done anything with CM9.
I currently have the ROM in my signature with Wind Kernel 3.5 and Battery Guru along with SetCPU installed and I get roughly 23 hours of battery.

Oh then I'm tripping then haha, I have a question though. I tried installing Liquid Nitro and every time I tend to wipe data, wipe cache, wipe dalvik, and wipe system. It just hangs at the LG logo and I haven't had the ability to try out your v7 or for that matter any of the other previous Liquid Nitro. I'll send you a PM since I can't really post in the development section due to my lack of postage xD :cyclops:
On the CM 10.1M3 with wind kernel 1.8, after one day of normal use with WiFi off and Data Off and Location services off I got Google Maps being the worst offender battery wise, the weird part is that I didn't really used maps that day. So even with everything off some service is still eating bat in background.

Hello
By following many, many XDA forums, downloading/ buying apps, trial and error, advice, ect. I think I may have a solution to the battery drain some of us experience with our devices. I feel confident my process applies to most phones running Nougat.
*This procedure will also cover most Android devices running 6.0 and up.
This guide is on the assumption you are rooted, and removed all bloatware. But may help some for the non-rooted idk.
*Create a Nandroid backup...Reboot.
*Delete any battery saving apps/ task killers/ antivirus apps.
1. Disable Wi-Fi. (You can re-enable later) Personally, I leave it disabled until needed.
2. Clear data in Google Play Services, Google Maps, and Google Play Store.
3. Go to Settings> Power> Battery Optimization> Reset App Preferences...Reboot.
4. In Settings, turn off Body Sensors, Bluetooth, Vibration, Location, Auto Sync, disable 'Backup and Reset'. (You can enable later)
5. Delete/ disable all apps you do not use. Less apps means less background operations while idle, a good thing. Delete Facebook/ Instagram/ Twitter apps, Viber, Whatsapp, and any other known battery hogs. (You can download again them later)...Reboot.
6. Follow this link. Thanks @MeggaMortY !!! The link cuts down some of the wakelock/ chatter/ cpu usage during idle.
https://forum.xda-developers.com/oneplus-3/how-to/guide-stop-google-play-services-t3549760
Follow the steps he has provided. I personally used MyAndroid Tools Pro for disabling Services and Broadcasts.
Next...
*Download App Ops from PlayStore. Open App Opps, and scroll down to Google Play Services. Select 'Prevent Phone from Sleeping' -Select 'Ignore'...Exit App Ops.
*Download Greenify from Play Store.
Using Greenify settings, select:
1. Shallow Hibernation, and Automated Hibernation.
2. Greenify System Apps (Requires Donation Package)...Exit Greenify.
*Download ForceDoze from Play Store.
*Personally, I use ForceDoze. (Try using your personal doze app if you wish).
In ForceDoze settings select:
1. 'Turn off ForceDoze While Charging'.
2. 'Ignore Lockscreen Timeout'.
3. 'Disable Wi-Fi during Doze'.
4. 'Doze delay '0' seconds'.
5. 'Disable Motion Sensing...Exit ForceDoze'.
*Return to phone settings, go to Power> Battery Optimization> All Apps list. Select ForceDoze, Greenify, App Ops, MyandroidTools, (Or whatever app you used to disable your services) as 'Do Not Optimize'.
Reboot to recovery (Also assuming you are using TWRP).
Select 'Advanced Wipe'.
Wipe 'Dalvik/Art Cache' and 'Cache'...Reboot.
Charge to 100%.
Remove charger. Let idle for 6+ hours minimum let to your battery monitor (BBB or GSAM, ect) have a good look. You can trim the excess fat afterwards...Then slowly add your social/ email/ sports/ weather/music apps. I would suggest you use your browser instead for these things. (Less battery stress during idle).
I also keep sync off, and manually sync, and only use Wi-Fi / Location/ Bluetooth when needed. (Optional, but saves battery)
**After you see your improvement, feel free to try out the device settings/ apps that balance functionality with battery savings!
*Mileage may vary depending on how many apps/ settings you have enabled (smartwatch, Facebook, ect. The less apps/ settings running, the better).
Sorry for the length. but I wanted to make this easy to follow.
Hopefully, this at least reduces some of the drain. Let me know.

Hello
By following many, many XDA forums, downloading/ buying apps, trial and error, advice, ect. I think I may have a solution to the battery drain some of us experience with our devices. I feel confident my process applies to most phones running Nougat.
This guide is on the assumption you are rooted. But may help some for the non-rooted idk.
*Create a Nandroid backup...Reboot.
*Delete any battery saving apps/ task killers/ antivirus apps.
1. Disable Wi-Fi. (You can re-enable later) Personally, I leave it disabled until needed.
2. Clear data in Google Play Services, Google Maps, and Google Play Store.
3. Go to Settings> Power> Battery Optimization> Reset App Preferences...Reboot.
4. In Settings, turn off Body Sensors, Bluetooth, Location, Auto Sync, Disable Backup and Reset (You can enable later)
5. Delete/ disable app you do not use. Less apps means less background operations while idle, a good thing. Delete Facebook/ Instagram/ Twitter apps, and any known battery hog. (You can download again them later)...Reboot.
6. Follow this link. Thanks MeggaMortY !!! The link cuts down some of the chatter/ cpu usage during idle.
https://forum.xda-developers.com/oneplus-3/how-to/guide-stop-google-play-services-t3549760
Follow the steps he has provided. I personally used MyAndroid Tools Pro for disabling Services and Broadcasts.
*Download App Ops from PlayStore. scroll down to Google Play Services. Select 'Prevent Phone from Sleeping'...Exit App Ops
Using Greenify settings, select:
1. Shallow Hibernation, and Automated Hibernation.
2. Greenify System Apps (Requires Donation Package)...Exit Greenify.
*Personally, I use ForceDoze. (Try using your personal doze app if you wish).
In ForceDoze settings select:
1. Turn off ForceDoze While Charging.
2. Ignore Lockscreen Timeout.
3. Disable Wi-Fi during Doze.
4. Doze delay '0' seconds.
5. Disable Motion Sensing...Exit ForceDoze.
*Return to settings, go to Power> Battery Optimization> All Apps list. Select ForceDoze, Greenify, App Ops, MyandroidTools, or whatever app you used to disable services as 'Do Not Optimize'.
Reboot to recovery (Also assuming you are using TWRP).
Select 'Advanced Wipe'.
Wipe 'Dalvik/Art Cache' and 'Cache'...Reboot.
Charge to 100%.
Remove charger. Let idle for 4 hours minimum. (You can peek in an hour, but you gotta start over).
Milage may vary depending on how many apps you have installed. The less the better.
Hopefully, this at least reduces some of the drain. Let me know.

I would suggest all the steps except the cache wipes in TWRP. Remove Whatsapp, Facebook, Twitter, ect. Disable google Now, Google Drive, Google Photos, (You can connect them later).
You want the minimum of apps interfacing with Google Play Services/ Android system during your first idle run.

I already have google drive, photos, whatsapp, Facebook disabled. Google now I'm not opted in if that's alright. I can still do the cache wipes in stock recovery as well. I do use the official twitter app and 3rd party twitter apps.

Give it a go with what you have installed. Preferable if you disable the Twitter apps, and re-enable them later.
Hopefully, you will see a better idle time.

My personal experiences taught me Google Play services is not broken, nor is Android OS. It's the inefficient way that apps send/ receive data, take constant analytics, perform background tasks, pushing notifications, ect. Then, Google Play services must tend to these apps, plus do it's own tasks, send/ receive data, analytics, and Android OS tries to keep it all together.
(It reminds me of Windows 10 high cpu/ disk usage while idle before I hardened it from Microsoft servers as best I could).
All of those processes hammer away at your cpu, and kill your battery while you sleep a little at a time. Or a lot.
I have no idea how to read a Logcat, and this will probably be seen as overkill to some, but my results speak for themselves.
Try it. You can always download apps after you see your result. Good Luck.

I would guess to say Samsung apps, Notification pushes, scanning for updates, ect. This looks like the behavior of Android dealing with multiple apps sending/ receiving data (Anaylitics, polling, crash reports, ect) causing the wakeups. My way (Unscientific) is to delete/ disable them all, and add them one by one, until you notice this behavior again. (Takes days of installing, and many idle runs).
Or, you could post the BBS idle dump (At least 6 hours idle) on the XDA Better Battery Stats forum, and let one of the guys take a look. They will tell you the offending app/ process far quicker.
But, at 1.0 drain per hour, you may be on the verge of 0.8-0.5 per hour idle drain (Or better). Wi-FI off will do even better. Simply engage Wi-Fi when you need it.
If you can, make a backup of your current setup, if something goes wrong, you can always revert back to it and start over.
Everything else looks great for a non-rooted device.

How would i be able to get the BBS idle dump? is wifi off and having data on overnight a better option in terms of minimizing battery drain? I also know i have scanning for updates off since i deny that all the time

Click where the circle is, You will see 'Share Data As'...Dumpfile should be checked by default. Click save.
It will be stored a the root of your memory card, or root of internal storage (Phone). I cannot remember which.
Access the dumpfile by plugging USB to computer. It will be a *txt* file. It should be visible as soon as you access storage. Then copy the dumpfile to your desktop, and upload to XDA BBS forum.
For me, drain is slower as I don't have any processes for Wi-Fi running at all in the background. You should try both ways to compare what is best for you. (Yes, yet another idle run).
Turning off 'Scanning for Wi-Fi' is good. Shutting Wi-Fi off completely is better. All those little processes add up. The less processes running, the better.
You should really practice the 6 hour idle runs, as more process come to the forefront in longer runs. Sometimes, extra idle drain from processes kick in after 3-1/2 hours. I used to get 0% idle drain in the first 3 hours, Then android would go nuts. LockerMaster app was the culprit. Got rid of it.
I am testing a faulty app that it's being faulty during deep sleep, therefore to fasten testing I would need an app which can force the phone to enter deep sleep mode immediately.
Any idea?
Macrodroid or Tasker maybe

Thanks guys!
Try disabling all power management apps ie all the toggles in Device Care are toggled off except fast charging.
Do not enable sleep for any; Developer options>stand by apps, all buckets should show as active if not power management is active.
Close apps when done with them especially ones like Brave.
The phone will automatically go into a deep sleep state at screen off unless a 3rd party apk is misbehaving.
On my 10+ running on Pie this is how it runs best and gets the best battery life.
Goggle Play Services, Gmail, Playstore, Google Backup Transport, Google Framework and Samsung cloud backup are prime offenders*.
Disable these and all Google, Samsung, carrier and apk feedback. I use Karma Firewall to find rogue apks and lock the phone down as well as a package blocker.
I also use Battery Tracker from the Galaxy Store.
Nominal battery usage is 7-10%@hour heavy usage like vids and surfing. Off screen usage with AOD on is 1%@hour.
*enable when and as needed

You'll need to play with it; what works with my configuration may not work for others.
These are my current observations. My stock AT&T 10+ variant is heavy modified and watched over. As I intend to continue to use the current Pie firmware, I continue to tweak it.
What I've observed though over the last year to my dismay is any power management interferes with functionality sometimes randomly and unpredictably. It actually ends up increasing battery usage within a few days although initially it may seem to improve it.
Apparently it causes system conflicts.
I have no power management active other than the screen is set to "optimize" in Device Care and even Device Care is package blocked then unless I wish to use it to clear the cache (which the factory load version does very well).
I toggle Google Play Services/Gmail on as needed and a few other battery hogs. Point is I know their status; no random shutdowns or apk failures... and the best battery life I've ever seen on this device.
You need to go explore, find the resource hogs one by one and find a way to tone them down.
All the shotgun get it done power management apks failed miserably for myself multiple times....
Android runs very well by its self once your rein in a couple problem apks.
Many times the factory loaded versions run better then their updated versions. Gmail, Gmaps, Device Care... may or may not be true on your load; trust nothing!

When I go into standby mode in developers options each app has 3 options. Frequent, rate, working set. What should I put them on?
Also what exactly does standby mode do? Is it manually disabling that app while not in use or only when you close it? As far as closing the apps, will closing them via the recent apps screen suffice or do I need to force close them?
And my last question is what do you mean by disabling an app such as play services?

It shows the app's bucket state when power management is enabled.
Your power management is enabled... and likely wasting battery even though it's suppose to do the opposite. If power management is disabled as I suggested, all buckets are locked to active.
Right now I have GPS enabled; I disable Device Health Services com as it was constantly accessing the internet.
Usually closing the app is all that's needed.
Use Karma Firewall and Battery Tracker to help ferret out bad apps.
Depending on your model, OS/firmware load, 3rd party apks and settings configuration your system may respond differently.
I have heavily modified them on this 10+ Pie variant; it's an ongoing process. I have around 88 apks packaged disabled as well.

Is there a way to prevent an app from ever being killed? I have 2 examples:
1) Fitbit app (background sync service, specifically) - when this stops running, some features on my watch quit working until I launch the app and sync manually.
2) Battery monitor app - I've tried AccuBattery (my preferred app), GSam, and BBS, but they all get killed and restart, and therefore give inaccurate information. BBS doesn't die as often as the others, but I don't like it as well. All 3 have persistent notifications, so I can tell when they last restarted.
I've set Battery Optimization to "Don't Optimize" for all of these. I've tried turning off all 3 of the settings under Advanced Optimization (probably unnecessary, no noticeable difference). I've also Locked each of these from recent apps. Are there any other settings I'm missing that could prevent an app from being killed? Possibly something new to Android 11? Fitbit and AccuBattery worked fine on my previous OP7P with Android 10.

Interesting, I haven't seen that before. Thanks for introducing me to something new. All of the apps in question are currently grayed out and say Exempted, so they shouldn't ever be put into standby.
Disable all power management*, Android does fine without it. Address any remaining power hogs individually on a case by case basis.
Power management will cause erratic behavior and can even increase battery usage even after its lame "adjustment" period.
To check if it is fully disabled go to Developer options>Standby apps, all buckets should show to be in their active state (and can't be manually assigned), if not power management is enabled.
Make sure allow background usage isn't disabled on the apps you want to run.
*yeah turn all those optimizing toggles OFF.
Only fast charging should be toggled on if you use it.

How does one disable all power management? I don't see any sort of global switch for that. Turning it off entirely seems drastic, but I agree that power management is generally more trouble than it's worth.
I did verify that the apps in question are allowed to run in the background and use unlimited data.

It seems like you're setting up right. Check the Stand by apps status.
When you first load Accubattery it gives an option to disable task killing in settings, Pro version.
Uninstalling then reinstalling it sometimes works for me; clearing its data does not. I was getting the same error message until I just reinstalled it
Just don't take Accubattery too seriously... it's useful up to a point.
I'm on Pie. Google really screwed up 10 and especially 11... so yeah it could something new as Google insists on changing things even if they're already nearly perfect
If that fails check with Accubattery for guidance with 11. They are responsive to emails.
They may also be punching out an update.
