As some of you have been complaining about your Infinity's poor battery life, I thought we should start a thread on getting more out of its battery. I invite you all to share your experiences, hopefully we could come to sth helpful together.
Perhaps when the development's carried on further by more XDA developers, we can split this to stock ROM and custom ROMs, as probably the latter will have more of these already included.
1. Arguably full charge and discharge does nothing good on modern Li-Ion batteries and it's rather advisable to keep it balanced - discharge a little, don't push it with charging all the time (however in case of the Infinity, as with many other devices, the charger will just stop consuming energy after [almost] fully charging your device). There is one reason for doing a few full discharges and charges however - so that the battery monitoring apps/widgets can learn more about your battery's life and power consumption.
2. Monitor your battery life and monitor it wisely (don't use power-consuming apps and widgets). I personally like Battery Monitor Widget, as it gives you mA and % / hour (either drain or charge), which is pretty cool, as you can see how much your usage exhausts your battery in real time. This way I've found out that switching the WiFi off while reading books actually gives me battery drain closer to 10%/h than 15%/h etc. You can see some other in this apps thread. Try different apps and see what fits you best. Don't rely on system battery usage stats, see what other apps show us and what apps and processes drain the most of your battery, show most wakelocks, etc.
3. Use as low power mode as you need (administered most easily through ASUS/Android notification bar on the bottom of your screen). There are three power modes:
power-saving (keeps your CPU at 1 GHz according to some apps, 500 MHz according to others) <- can give you up to 2 additional hours
balanced (keeps your CPU at 1,5 GHz)
normal / performance (keeps your CPU at the highest speed - in stock kernel 1,7 GHz for the 1st core and 1,6 for the others)
You have to try these for yourself. Most games run well on balanced, but may sometimes need the performance mode (keep in mind that overheating your CPU and GPU may cause the clocks to actually slow down). You may also find yourself happy with the power-saving mode, which really helps your battery to last longer, but I've noticed issues with some apps while running it (problems with pdf rendering, for example), as it probably changes more than just the CPU clock speed, but also the system behaviour. I hardly ever leave the balanced mode, mostly when curious about benchmark results
There are also different CPU governors in Android/Linux kernel, which you can change if you are rooted, but perhaps leaving the default "interactive" one on should serve you well (you can also try "conservative", but it has been argued it doesn't save your battery so well in the long run).
(if rooted) You can also use CPU management apps like SetCPU, create your custom profiles or use the default ones according to your needs (for example ).
4. In ASUS setttings switch on both power-saving options at the very bottom of the list (WiFi and dock deep sleep [the former is the same as choosing "never" in WiFi advanced settings]).
5. Keep the screen brightness as low, as you can. It's better to adjust it manually through the notifications bar or a widget than to switch auto-brightness on (some recommend LUX app, personally I had problems with it trying to outsmart me when I was doing some manual changes). I like to keep it around 30-40% indoors during the day and 0-10% at night.
6. Switch WiFi off when you don't need it, unless you need it on constantly.
For me, it sometimes also helps organise my work too, when I don't get constant notifications or when I'm not eager to browse the web all the time, when just reading something and taking notes.
7a) (if rooted) Make your device fall into really deep sleep...
Add these to your build.prop file (see the thread on tweaking):
ro.ril.disable.power.collapse=0
pm.sleep_mode=1
7b) ...and make it scan for available WiFi networks less often, for example every 180 seconds (same as above):
wifi.supplicant_scan_interval=180
8. (if rooted) Switch off all the apps you don't need that auto-start on boot with a program like System Tuner.
(f not rooted) Use auto-killer for the apps you don't need (if rooted you can do the above two together as well).
You can also deactivate unused apps (settings -> apps -> [select app] -> deactivate). Remove bloatware, too (see the first few posts).
9. Adjust your minfree values, so the low level system task killer will take care of the apps running in the background for you (see the thread on tweaking). You can try with different settings and see what's better for you. Some apps drain your battery life even when you don't use them, while others don't and it's better to leave them in the memory than run them all over again every time. Do some tests and see what's best for you, if you have time for it.
10. Switch auto-syncing apps to lower values when possible (sometimes PUSH is better, sometimes worse for your battery life).
11. Keep it simple. Too many funky animations, floating wallpapers, lots of nice widgets will make your battery drain really fast.
12. Try different custom launchers, you can set more UI behaviour rules in these (see this apps thread).
13. Use a dark wallpaper and dark themes / night reading modes (see why).
PS JuiceDefender reported to having disabled deep sleep, so stay away if possible.
Hotmail app has been said to trigger wakelocks, while overriding system wifi sleep when screen is off, so keep that in mind if you want better battery life over constant e-mail syncing.
Hit [THANKS] if it helps.
First of all, thanks to d14b0ll0s for yet another great write up. I am one of those concerned with the battery life of the Infinity. Though some review says it got up to 9-9.5 hours with BALANCED mode I believe is the mistake. By using Power save mode, I think we can potentially get to that level but still hard.
My system is NOT rooted, but I have noticed significant change in my battery life so far with following:
1. Balanced Mode to Power Save mode.
This gets me like extra 2 hours or so. WIthout this change, 5-6 hours for my usage and with this it goes up to 7-8 hours screen time.
2. Under Wi-Fi Setting change Use wifi during sleep mode (mine is in Japanese so exact wording may be different) to never. Default setting was always. Prior to this change, I lost quite bit overnight unplugged; however, after the change it loses negligible amount.
Now rather than these, I am trying to play around with Juice Defender, which was recommended by d14b0ll0s in best application list he created. I have initially downloaded Juice Defender Free edition, and noticed may be minimal gain over #1 already instituted. But concept was great. So I ended up purchasing Ultimate edition, which allows us to control when to turn of WIFI per individual application based without Root i.e. while reading PDF I don't think I need WIFI connection.
https://play.google.com/store/search?q=juice+defender&c=apps.
I am still tweaking and playing with Juice Defender, but I am certain without change in #1,#2 (which are actually taken care by Juice Defender in its own way), I can gain same battery life and my hope/guess is I can get even more battery life.
So in conclusion, for those not rooted try Juice Defender (at least free version). I will let you all know how the ultimate version does in next couple days.
Thanks for this! ^^ Post 1 updated.
Have you noticed what power-saving mode changes apart from CPU (& GPU?) clock speed? Does it change auto-sync settings or unload some modules? I'm not using it, as it is too slow for me to render big pdfs consisting of scanned jpgs. But when I'm reading them with WiFi off on balanced, I normally get 9.9% drain per hour according to Battery Monitor Widget, which even with some other things that I do from time to time and some additional rendering when opening new files should give me about 9 hours on a single charge. Browsing over WiFi gives me about 7.
The Wi-Fi settings you mentioned are the same as WiFi power-saving settings on the bottom of ASUS setting list, but I've clarified that in post 1 now.
I'm happy JuiceDefender helped you, it's good to advertise it here. I'm adding the info about your post apart from the link to the list of apps.
Thanks
I would also add that it's good the deactivate unused apps/widgets (settings -> apps -> "select app" -> deactivate)
it's only possible for apps which cannot be uninstalled
Good point! ^ Added (-> p. 8).
Mine will be here this weekend.
Thanks d14b0ll0s
Look very useful! I'm about to try.
I think the standby time is awesome. Wifi off, power save mode enabled and left the tablet over night right after full charged battery w/o dock. After 10h still 100%.

#nice
The system measuring system isn't exact, and early on so are all the indicators, so don't rely on it too heavily. There may be a variance of 1-3% and a lot more in the usage indicators. Try different battery / apps widgets and compare the results.
Anyway, deep sleep is nice indeed. It normally drains about 0.2% (-0,5%) per hour, mine is now 98% after the night off the charger and responding to a few e-mails in bed
Thanks for the info, it's appreciated.
Antutu's Battery Saver worked great on my 101, I'm observing how it will regulate the power drain on my 700. Hopefully it will keep the back of the tab cool as well.
i think the problem is when you have wifi on!

this is good when you have wifi off. however, when you have the wifi on, it shows 80% wifi and 20% screen consumed by battery. you can stop network access by disabling wifi from Asus customized settings and also in wifi setting, you can keep wifi on during sleep to NEVER. this helps a lot..
Stock battery (usage) stats are not relevant, use other battery apps or widgets for that.
I've heard good things about AnTuTu's bat.sav., but also that it doesn't let you have more insight into what it's actually doing, so JuiceDefender seems a better option in that matter.
d14b0ll0s:
Do you know the specific voltage setting / configurations coming out of the usb line?
Is it 16V and how does it distinguish between 16V and 5V on the single USB cable.
For example does the voltage cable go on different lines for 16V and 5V for the TF700?
Or is it 16/5V dual switchable on the same power cable?
I'm asking this is because there's interest to charge the tablet by using alternative methods such as mobile battery with 16V setting.
If so, then does a DC to USB cable be suffice for the job? Or is the cable wired differently as proprietary ASUS?
Thanks!
Sorry, I wouldn't know that. There some ppl here that are doing some testing with the batteries and hardware, perhaps the_kreature or MartyHulskemper could know something. You should post it as a thread in Q&A too.

First of all, the charger gives 15V, not 16V. Avoid giving your tablet too much voltage as that can kill it...
Secondly, the included cable is a USB 3.0 cable and therefore has 5 extra pins (you can see them if you look straight into the USB plug). These extra pins are used to get 15V from the charger. I don't know exactly how that works, but I guess the tablet tells the charger it wants 15V over the power lines (same power lines as 5V) rather than the charger giving 15V over these extra pins (because that could be devastating to other USB 3.0 gadgets). This is why the tablet won't charge if you insert an old (USB 1.0 or 2.0) extension cable between the charger and the tablet.
Hey I'm running with wifi on during sleep and I seem to get great battery performance (2% loss over 11 hr standby). No build.pro tweaks so no deep asleep our anything like that. I'm wondering if anyone else has gotten similar performance?
I thought it was interesting because the results were the opposite on my tf300t, and my usage pattern hasn't changed much between the two devices.

Same here. Battery life on deep sleep with WLAN is great!
But I think the Infinity needs a lot of power while reading news, tapatalk, Reader HD..
Not more than 4 hours Screen On Time!
And that with balanced mode and 50% brightness.
Any problems with the fifth companion core?
PS: Is there an app which shows the activity of the different cores?

this is crazy, i got my tablet on monday, used it about 3-4 hours restoring all my apps and signing in to everything, and i havent used it much since but today, i'm still at 76%, havent plugged it in it or docked it. I also forgot to mention my dad played with it a bit also...prob about 1 hour
So i got installing all the battery saver apps, greenify etc... they all close apps and not much else, my version comes from the mind of an electronics engineer view point...
hardware drains power NOT some little app running in the background! (Purely software programmer logic... )
So my app grabs what states wifi/gps/bt/modem at the time the screen goes off...
When the screen comes on, it re enables them! Eg go bed with 95% wake up with 94% put in your pocket it just does it...
The 2nd feature is the lost/stolen phone feature while the app itself can not get your gps data (no permissions for it) it can switch gps on/off...
So you send "on" without the surrounding quotes, the app will then switch on gps/wifi/modem/bt... it then disables itself
Now you can use wheres my droid or any other location finding app to easily pinpoint your lost or stolen phone (try getting a location with gps/agps/data disabled which people often do to save power!)
(Includes option to keep wifi/gps untouched from the app)
as for ads!... the ui has 1 ad, no popups or notifications ... and when activated the activity with the ad on is destroyed and can't touch battery life ... at all
Craig's Root Battery Saver!

Well done
Holy crap! Someone replied (first for me here lol)
Thanks!
To be honest, your app is great when it comes to save battery, but in my opinion your approach is plain wrong in terms of the main purpose of a smartphone - receiving notifications in a timely manner, not when you turn on the screen manually. The same purpose can be achieved by using DS Battery Saver, which will in addition turn on mobile data once per specific time interval to receive push notifications.
And you should reconsider your opinion about "software does not drain battery but hardware does". Check this great thread for example. I am using a combination of different apps (Greenify, Amplify, Power Nap) to tame aggressive services/alarms/wakelocks and I am able to achieve a battery drain close to 0.0% per hour while screen is turned off with WiFi, mobile data and location turned on the whole time without losing instant notifications.
The app supports wake up notifications (well, will... the app's not quite finished yet, been too busy to get everything finished)
If you had gone to the playstore you'd have seen
Also you might want to reconsider what i said..... hardware drains it not software!
You refer to wake locks ... well believe it or not, wake locks turn on hardware which drains the battery, i program microcontrollers with the esp8266 / bluetooth / compass / etc ...
Software can only drain the battery if it's purposely trying to max out the cpu, and if it did you'd know it's malware... there are wakelock detectors too

I came across this, therefore my reference to DS Battery Saver, that already is capable of exact those things. Nevertheless, your app is doing what it was designed for - saving battery (and this is pretty good, indeed).

Well, I am familiar with what wakelocks are. But without software, that produces a wakelock, there would be no noticable drain, right? Thus we can go round and round here, I guess. From my point of view the most battery drain on an Android device is the result of poorly programmed software (which results in an unneccessary wakelock) and alarms waking up your device, not from ****ty hardware. You can hunt down those wakelocks/alarms by using apps like Better Battery Stats or Wakelock Detector and reduce them to a minimum without losing functionality. Therefore I consider this as a better approach.

Unless the software drains it by intensive cpu work, anything else has to be hardware, if i power a gps module, talk to it via uart to enable/disable it... then it's hardware doing it not software..
Take Qualcomm, the newer cpus support an embedded DSP
https://gigaom.com/2014/12/12/5-things-to-expect-from-qualcomms-flagship-mobile-chip-in-2015/
Qualcomm*made that feature possible*in the Snapdragon 800*with its DSP, and they’re pushing hot words even farther. New devices will have the ability to passively listen, using only a small amount of power, for more than just the word “OK.” Qualcomm calls this feature Snapdragon Sense.
The first feature it will enable is a much faster Shazam search. So if you find yourself too slow on the draw when trying to identify unfamiliar music, you’ll love this: When you boot up Shazam, it’ll already have been listening just a little bit, so it can identify the song in a few seconds.

As hardware gets smaller and uses less power, then things like the embedded dsp chip will allow you to use wakelocks without little drainage, but were no where near that yet...
think of it like this... software simply carries instructions which can turn on hardware via a field effect transistor, that binary 1 value shows up as 3v logic and the fet begins to conduct between the drain and source, this sets a flip flop and the hardware starts wasting power...
Or to put it another way after the software enables the hardware via a gpio the software stops, or better still, show me software draining the battery with all hardware services disabled... it can't
Good
Does it really work ..
Don't you believe the title? (Really works!)

True words. I can also see your other points and do agree with them. But as you said, we are not even close to a system where wakelocks do not drain as much as they currently do. Would we have such a system, your app wouldn't be required, I guess. Therefore taming the unneccessary wakelocks is a good way to achieve a great battery life without losing functionality for the moment.
Awesome
Awesome!!!
Can't open the settings and this sound makes me rly angry lol. Why it makes this sound? (even my phone is silence)
Gesendet von meinem ONE A2001 mit Tapatalk
There are no settings... work in progress (says so in the play store readme)
I've had the flu for the past week so i've not been developing much... expect updates shortly to remove the "settings" option which annoyingly is placed there by default... i never put it there
The sound is cool no? ... it plays a low volume sound to indicate the app is working!
Alright, update includes support for android 4.1 for gps now... i'm slowly working my way through android oddities and different techniques to switch hardware / on and off and with 5 phones to use 4 of them use kitkat!
Had to stop for a break i've had the flu all week, throwing up constantly, later on i'll add the finishing touches to wake up notifications as right now it's extreme power saving mode...
Stay tuned.... oh and i found a bug supporting lollipop, fixed that too, so if you have lollipop and it never worked, it should now ...
Antibiotics did the trick! It was sadly not the flu but some rare bug...
I've almost finished the autowakeup every x minutes 5, 10, 20 min intervals..
Unless someone here can think up a value or maybe add it as an option.
.
I removed the blocking side of things prior i used a thread/sleep now i use a timer event this stops the lag when unlocking the device on older models...
nive work :good:
I dumped the smart check (as far as i can tell anroid never fails, so i removed it)
It should now be seamless between lock screen and the main screen without any more lock up due to the threading...
Enjoy!
great!! will try it. thanks!
The guide to get incredible battery on your S7E!
A lot of people are having trouble to push the 3600mah battery to the absolute max, so I will here show you how to do so. This will mainly be a link to another post made my @v7, which have made an incredible guide to get a good idle drain. I will mainly explain what works on our S7E and what not, while giving a few other tips. Most of these tips can be found all over the internet, but I just want one thread, where they're all collected, so people can read every tip in one thread. As most guides are general through out all devices, they is what works and what don't on our devices. You're free to share your own tips!
REMEMBER TO MAKE A NANDROID BACKUP. ANYTHING YOU DO ARE NOT MY FAULT NOR ANYONE ELSE BUT YOUR OWN FOR MAKING THIS CHANGES!
Firstly, use a debloated rom.. That do a lot..
As said, @v7 have made this guide here. Remember to thank him!
Greenify:
Get the donation package and greenify everything that runs in the background and you don't need push notifications with. With the Shallow Hibernation, it still runs nice and smoothly when you open them. After that, you enable GCM push for hibernated apps and look, if any of the apps that you need push notifications for, supports GCM push and if they do, hibernate them. You will still get notifications, but remember to check "Do not delete notifications from hibernated apps".
I have almost everything hibernated - Maps, Facebook Messenger etc, when still working smoothly - besides Play Store, as that gives problem with paid app licenses. I also enabled Aggressive Doze. You should whitelist the same as in Powernap, that will be listed below here.
Amplify:
I have everything in mentioned in the thread Amplified without problems. I hadn't touched the services, but they should be save to disable anyways. Network Location service, have given me problems with Android Wear communication before.
Powernap:
Here comes where you need a permissive kernel. The SuperKernel that just came out, is the only one on XDA for now. In Powernap you should whitelist the following
Amplify
Android System
Google Account Manager
Google Play-Services
Google Services Framework
Greenify + Donation package
Apps you need push notifications from (like Facebook Messenger)
Xposed Installer
Your alarm clock
Basically, you should whitelist anything that you want to run in the background while the screen is off.
Better Battery Stats:
Check the app after a sleep, but leave everything on as if you were using the phone (data, bluetooth etc) as this is about lowering power usage on normal use and not seeing how long standby time you can get while everything is turned off. GCM_Reconnect and Heartbeat might be high for Google Play-Services, but for me, limiting them gave late or non push-notifications, but test it yourself (remember to restart after limiting/unlimiting).
All the small things:
Turn off location history
Turn off services you don't need and let Tasker control it. (Turn GPS on when maps open, hibernate and turn maps of when closed etc)
Turn off bluetooth and wifi scan all the time
Get Smart Network from Xposed and set your network to Edge when screen is off and 3g/4g when screen is on.
A dark theme with dark icons can save quite some power
Samsungs own greyscale can be enabled in accesibility and then triple tab on homebutton, when you know you're out for a long day.
UPSM Manager from the Play Store can add apps to the Ultra Power Saving Mode, so you can add apps like Facebook Messenger and suddenly it's way more useable.
Use Tasker to force sync, instead of having it activated. I force sync every 2 hours with Tasker + Synker
I have turned off features that I DO NOT USE. Under Advanced Functions, almost anything + edge screen features.
More connection settings and "always search for devices" - Off
Custom kernel settings:
There are no custom kernel out on XDA yet that supports full Synapse, but the Echoe Team have successfully build one.
I have set both governors to conservative, which actually is impressive smooth, while it should be the most battery saving governor which don't lag (like Powersave).
The I/O schedulers should be set to noop which have quite good battery life, without limiting performance too much. I haven't felt a difference yet.
TCP Congestion is set to Westwood (but I think that is standard anyways).
Everything have been undervolted by 25mV. That is nothing from a battery saving perspective, but well, i'm still testing.
L Speed from @Paget96 (thank him!) here is quite nice too!
I haven't had any lags with these battery saving options yet. Everything not mentioned is just standard.
OOM Killer - Enabled
Cache Reclaiming - Minimum
Kernel Tweaks - Light
Kernel sleepers optimization - On
Battery improvement - on
Wifi sleeper - On
Flag Tuner - On (Some people on S7E have mentioned problems with this.. Lag, reboots and bootloops, but I haven't had any problems).
IO Boost - On
I have power saving mode enabled, with background data enabled and my phone is still butter smooth, Also, check for apps to add in the battery saving menu, as I have enabled some apps I don't use or need notifications from, manually.
I get around 5-6 hours SOT where 3-4 of them are Clash Royale, if not more.... Yeah, I game quite a lot.
I think that was all for now, but I will keep it updated when I get new ideas to push it to the limit.
This is still keeping the phone "smart", as you adjusts it for your needs.. Inb4 all the people saying, why buy a smartphone if you disable every feature.
hmm that would kill performance in tekken and AB2 as those games are heavy on QHD but i try it nonetheless, ty.

There are two kernels on here now.
You could ask for permission to get on the forum where the kernel is or you could simply wait. I knew it would only be a question about days, before there would be kernels on XDA too.

Exactly.
I've gone through a lot of these kinds of tweaks in the past, and generally found having to re-load apps and disable features I like having wasn't worth the small battery life increase I saw.
That said, Everyone uses their device differently though, so what doesn't work for me may work well for others. Remember that before you say I'm spouting nonsense about small battery life increases.

I certainly agree that it depends how you use your phone. But if you only rely on a few apps when display is off, like a few messaging apps, Power Nap can certainly increase your battery life. I have a idle drain around 0.0-0.2% (note, 0.0% is not the same as zero drain.) and I still receive messages, and Tasker turn everything on that I need when I need it (GPS, nfc, sync and so on). So if you just install the apps, yes it decreases functionality a lot, but by tweaking it to exactly match your usage and not limiting what you use, you can certainly get increase battery life without losing features. I use my phone the same way now as uprooted, not limiting anything I use..
Most people have a lot running in the background they don't really need or depend on or that can wait till the screen turns on.
Hi,
I come from sony xperia z3 compact, which had a really cool feature, stamina mode, and what i especially liked about it, is that when it was activated and you locked your phone (screen lock) - it restricted ALL background data, no exceptions. Only when you lighted the screen, it would activate the data. Does anyone know, how can i achieve the same feature with the Samsung S7. Basically all i want is that if i lock my screen, all the background data is truly disabled?
Samsung's equivalent of stamina mode would be the "Power Saving" option, of which there is two tiers("Mid"and "Max"). Background data is restricted by default in both modes, although I think the "Mid" tier still allows it periodically.
Yeah i saw them, thanks for the input, although the MAX setting makes the phone lose its features. I will try the MID setting (i disabled the limiting of cpu and some other stuff, because i want it to function normally when i use it). Maybe theres an app, that will make it work just like i want it. Because the s7 battery should last longer - with sony, wifi off and background data restricted, i sometimes got like 4 days without charging. I am not a 24/7 nose in the screen type of a guy anyways, i mostly call and when neccessary look stuff up on google and read my mails. Would be nice to extend this S7 battery to around 3 days or so with such usage.

Yeah i saw them, thanks for the input, although the MAX setting makes the phone lose its features. I will try the MID setting (i disabled the limiting of cpu and some other stuff, because i want it to function normally when i use it). Maybe theres an app, that will make it work just like i want it. Because the s7 battery should last longer - with sony, wifi off and background data restricted, i sometimes got like 4 days without charging.

You can add *some* apps for use in MAX mode, most notably WhatsApp. Maybe use Tasker to toggle data when the screen turns off?(Would need root though). But yeah, there's only so much you can do for a big AMOLED paired to a power hungry SoC I've never known more than a day and a half's usage though. Perhaps other people have better suggestions.
so far its been 6,5h since last charge, and its on 91% - with the mid power saver mode, cpu limiter disabled, screen res on FHD, screen brightness about 40-45%, wifi off, and gps on high accurancy - it looks somewhat promising. I'll see how long it will last on that charge and proceed from there.
Ive got a SM-N770F/DS and I always have medium power saving mode on. I have also always had an issue with Google Maps not wanting to detect location after I turn the screen off. I assumed it was a google issue until I turned optimized power saving mode on today and Maps suddenly started reading my location and giving directions while the screen was off. Is it possible to disable the "prevent background location access" part of medium power saving mode? Long pressing my power saving settings doesnt give any options to do this, im thinking my only option is to root. Would rooting fix this? If so, does anyone know of some roms on here that would allow me to do this? I dont care about much else from the rom, I like the phone as is and this is the only issue I have with it
Do not toggled on any power management other than the power mode (optimized) and fast charging.
They screw up functionality and increase battery usage on my unrooted 10+ running on Pie.
In Developer options>standby apps all buckets should show as active otherwise power management is active. Android will manage apps well without any power management options turned on. Track down any remaining battery hogs on a per case basis and deal directly with them. Sometimes closing the window gets it done like with Brave. Others need to be dealt with by package disabler and/or Karma Firewall.
This may or may not help you.
Gmaps is crapware. Runs best on original factory load and is a parasitic drain wanting to constantly run in the backup from boot sucking up battery and bandwidth.
Unlike you my goal is to keep it from doing this
Also review Gmaps notification and other settings. It's a mess; buried settings galore.

I feel like I have experienced the opposite. I felt like my battery was draining faster with optimized on today (2nd pic) compared to the past few days with medium power saving on (first pic). Obviously more testing needs to be done to see. Going off of the pics I lost about 50% each day, so optimized seems to be worse for battery life but the reduced screen on time makes up for it in this scenario
