[GUIDE] Battery Management for noobs

Hey guys,
So after many months with the XT720 and alot of flashing and trying to get the most out of my battery, i've come up with a few conclusions about battery life in general and how to extend it. I thought I'd share here. This is mostly aimed at people who are new to android and have not experimented like some of the more advanced users we have on this forum. Hope you find this helpful and please feel free to make additions.
General Battery Info
The XT720 was my first android phone, and I came from a long line of typical nokia phones whose batteries would last for ages. I had no idea the kind of power an android device would use. When I started out using it, i was surprised at how quickly the battery would die. You'd think with advancing software we'd have better batteries but sadly batteries are lagging behind in technology. Generally speaking you can expect the following battery life from your XT720.
Heavy use: 10-14 hours
Moderate use: 16-20 hours
Light use: 1 day - 1 day 12 hrs.
Note: New batteries improve with each charge cycle. It is recommended to go through a few complete charge cycles when you buy a new phone. After that, complete discharges are not recommended and its smart to start charging your phone when it hits the 20-25% mark.
How to improve battery life
1: Battery Calibration
If you've ever flashed a new ROM, you must have noticed a sharp decline in battery performance. This is partly due to old battery statistics left behind from your old ROM. Android is a smart OS and collects information over time. The more you use it, the more accurate it gets. In the same way it collects information from your battery usage and reports your battery percentages according to that. When you flash a new ROM, sometimes android thinks that your battery is 100% when its really lower than that and that causes relative reduced battery performance. To deal with that it is recommended that you use a nifty free app called Battery Calibration from the android market. What this does it removes the old battery stats and allows your new ROM to create its own battery stats. Charge your battery to full, use the battery calibration. Drain once till phone turns off by itself and charge to full again. You will notice a sharp increase in battery life.
2. Battery Managment
We all know that android has its own battery management built in but it usually doesnt give complete information about the phone. For that you need to dive deeper into the settings. Usually if you experience battery drain its because of a rogue app and believe it or not some common apps you wont think off drain unnecessary battery. To see your complete Battery Stats input this code into the dialer.
Code:
*#*#4636#*#*
This will take you to a bunch of options. What you're interested in is Battery History. When you tap that it will show you two drop down menu's.
1) Other Usage
2) Since last unplugged
Other usage shows you how long your phone has been running and how long it has been asleep. Also shows you how long your wifi has been on and running and how long your screen has been on. It is important to see how long your phone has been running. For example if your phone has an uptime of 20 hours and its been running 5 hours out of that. Your run time is 25%. Which is very good. Sometimes an app can run even when your phone screen is off. This will represent a longer run time even when you have your phone lying on a desk or something. See this setting and correlate with the amount you have used your phone. Does it seem normal? If no then use the first drop down menu and select
Partial Wake:
Partial wake is basically, any app which takes your phone out of sleep mode to use the CPU even when youre screen is off. These are apps which need to sync or use the phone resources. In this you will see a list of apps and how much they have caused a partial wake lock. See anything unsual? For me one app that caused unsual drainage was latitute. Yes, i had simply signed into it and i didnt know it was updating my location every 5 minutes. Extreme battery drain for me even when my phone was idle. See which app was draining your battery and either tweak the settings or remove altogether.
GPS, Sensors, CPU:
You can also see these in the first drop down menu. Certain apps like screeble use the sensors alot, and hence cause drain. Obviously games, camera, will stress the CPU. See if anything is causing drain in that and adjust accordingly.
Miscellaneous Information
After you have dealt with rogue apps that you don't use that drain youre battery your battery life will depend on how you use your phone. But hopefull these tips will help you with increasing your battery life. I do have some more information on different settings and supposed battery saving applications.
Autosync: When you enable auto sync, you allow google and other accounts to sync on a regular basis. This is important for people who need to use push email etc. It does not drain battery IF you tweak what you need synced. In google for example you can have your contacts, calendar, google+, google reader, gmail all to sync by default. If you just need email, please untick the rest. This will help you save battery life. Increase your update times for facebook and google+ if you dont recieve many updates all the time or turn them off altogether. If you have many services syncing at the same time you will get battery drain.
Wifi Sleep Policy: This is sort of a hidden menu. If you go into wireless & networks >> Wifi settings >> settings key >> advanced >> wifi sleep policy. This has three settings. Never close down wifi, never close when charging, or close with screen off. If you choose never your wifi will always be on, which will in turn crunch the **** out of your battery. If you use it off with screen off, remember it takes about 5 minutes to turn the wifi off. I personally use the never with plugged in. Its an intermediate. So when im plugged in wifi always stays on and when im not it follows the screen off protocol.
Wifi Vs Mobile Data: Having mobile data on all the time, does not drain battery. The only time the battery gets drained is when the data connection is active i.e you have many apps on autosync youll see your battery going down. If you arent doing anything and your phone is connected to Edge or 3G your battery will drain regularly. 2G networks drain less than 3G keep that in mind. If you are actively using your connection, wifi will take less battery because speeds are faster and you will be using it for a little time. Also your signal strength has alot of effect on battery. If you have crappy 3G signals your radio will actively be searching for a connection the same goes for wifi. That is important to keep in mind.
Control Background data: By selecting this option you can allow or disallow apps to connect to data without any permission. Some apps require this like the android market. If you uncheck this apps wont be able to sync automatically in the background.
Milestone Overclocking: This is fairly obvious. The higher you overclock with higher vsel the more battery drain you will have. Some use set cpu with profiles but I found that if i set the setcpu too low while idle It takes time for the cpu to charge up when i recieve a call or turn the screen on. Ringtones lag etc etc. I let android do my CPU management and its fine. and comfortable setting would be 850 MHZ, 56 vsel but you can change according to your phone usage.
Juice Defender/ Screebl / Task killers:
In my personal experience with juice defender ultimate I found that with the above precautions juice defender didnt make much of a difference and actually used more battery. First off theres an extra process going on in the back. Second activating and deactivating the connection everytime the screen goes off uses more juice because your radio has to search for the signal hundreds of times as compared to not having it in the first place. Screebl is good if you dont want your screen to annoyingly turn off while youre doing something but it surely doesnt save battery life. Task killers are a no no for android. They kill tasks which start up anyways, its better to use autokiller memory optimizer which tweaks androids internal memory settings and allows for more free ram without killing processes without reason.
System Apps:
Some system apps run uselessly in the background specially with stock ROM's this is called bloatware. Remove all unused system apps with titanium backup to stop them from running in the background for no reason at all.
A final word
Finally after all this tweaking, just use your phone as normal. Dont worry about the battery all the time checking how much its drained, itll mess your head up and make you enjoy your phone less. Battery temperature also changes battery life. Keep your phone out of the sun or in hot places.

Thanks, good article.

Very detailed and useful

Thanks for this interessting article!
Could you make a list of the bloatware that can be safely removed?

I figured this would just list all the usual stuff I've heard. I'm glad to say I was wrong! A bunch of useful info here I now plan to put to use. Many thanks
Might want to mention the display being the biggest drain of battery on this phone. Setting it to automatic brightness or lower will increase battery life. I love the screen at full brightness so I don't really follow that, but for those looking to squeeze some extra time and don't mind less brightness...

Thanks guys, glad you people found it useful.

Yes! Can't believe I missed that one out. In the start id use the lowest brightness setting, which would be fine indoors. But outside it was impossible to see the phone because of its insanely reflective glass. Since we have an ambient light sensor I use it on automatic and it does a good job. Full bright strains my eyes abit thats why I dont keep it on full bright So for people really wanting to save the juice you can keep your brightness on the lowest level. Also when you take the phone out of your pocket and use it, its better to put the phone to sleep with the power button than let it timeout by itself. Those 10-15 seconds for each time you use phone count towards many minutes of unused display time in the end and does make a difference.

This is a very gd post with lots o useful info!! ok i have a qn, is using the phone a lot while the charging good for the battery? And if u let the battery charge even though its already 100 percent for an hour good? srry if it is noob qn...

1. Using your phone while charging does not affect your battery life, and is neither good nor bad. It is perfectly normal to use your phone while charging and is sometimes recommended while doing battery intensive tasks for example navigating while driving, wifi tethering, playing memory intensive games and finally outputing video through HDMI.
2. Overcharging was a phenomenom is older lithium ion battery. New batteries have bypass circuits. So when your phone reaches complete charge, it does not charge any further. So you should not be worried about overcharging your XT720.
Hope this helps.

Excelent article and good quality info. Thanks and best regards!

awesome article! Great information. Thanks a lot for putting that together. I have already started using a few of the tips mentioned.

Best battery-saving app 2012?

Which is the best battery-saving app 2012?

Mugen power

Hi,
In my little experience, there is no software that makes alot of diference, normaly what i do is:
disable motion
insert *#9900# and disable Fast dormacy - check is your network needs this
disable sync for accounts
disable GPS
disable wifi gps
disable wifi when not using
set brightness level to auto
set wifi sleep policy to when pluged in
Of course there are a couple more things you could do, and again this is what i do cant say it will work as good for you.

rooting.

Tasker
With it one can automate almost everything on the phone.
It's almost like programming i use it all the time and there are a lot of examples on this forum. http://forum.xda-developers.com/showthread.php?t=1110775

Juice Defender Ultimate + Battery Saver Pro (by Antutu).

I tryed a few battery saver apps but no longer use them as i found if i turn auto sync off, change wifi sleep policy to never, untick network notification, and use task manger frequently to kill unused apps my battery lasts a lot longer. I also use easy task killer and set it to kill all apps every 30 mins. im using king cobra v1.1 for evo 3d gsm and the battery life is amazing!! just swapping battery's over now and its nearly 9pm!!
If any one needs any help rooting or unrooting the evo 3d gsm hboot 1.4.9.0018 let me know as i have done it a few times now. I unrooted my phone back to ***locked*** s-on with no traces of rooting, then checked for ota updates, wouldnt of installed them tho even if there was one!! then downgraded back too 1.4.9.0007 and rooted it again with revolutionary.

forgot to mention auto brightness is a must. and i also calibrate battery after installing roms . can anyone please tell me if calibrating the battery every time it gets to 100% is good or bad? thanks.

When you use an xperia mini pro like me, with just 970 mAh, you get to try all possible battery savers... and unfortunetly no one of them makes the exception... actually as said evilchild, they don't make difference...
just disable everything that may drain your battery, your launcher effects too can be in cause, get rid of unuseful apps, put your brightness to lowest levels or just get it to auto if your rom use it... choose the best profile for your CPU... and with this you are good for 10 new hours in your daily battery life.

I'm not sure a 'battery-saving' app is real.
They just disable some features that we can manually do that. They just make it automatically disabled.
But, 2x Battery is good. It could disable Wifi or mobile data while the display is off.

one touch battery saver is awesome. create a widget to enable/disable wifi,gps,sync,brightness,bt,data ect with one touch!. free on google play

Yeah. There's a thread somewhere which gives real battery saving tips

I tried some apps, but I didn't found one which really improved the battery.
In my opinion the best method is to reduce the brightness.

From the apps I tried out and used, almost all of them just disabled certain things, or tweaked settings that I could have done on my own, and eventually did do.
I found it easier to just go on a sub forum for the phone I had at the time and look up tweaks, tips etc.. I'd say doing this helped me more than any app I found previously, and was easy to do.

Dolphin companion is good and gives more remaining of time.

I use juice defender and the setting: "Only 2G"
3G takes a lot of battery..

None. There are no working saving battery apps, not a single one.
What a battery saving application can do is to change the phone configuration to a lower energy one, just like lowing brightness, disabling data packages and such, to sum up, things you can do by yourself and you'll save the battery that that application consumes.
The best way to save battery is to make a proper use of your phone:
-Disable gps when you don't need it.
-Turn off bluetooth when not needed.
-Keep screen brightness low at all time.
-Disable data packages before going to sleep and enable them again when you wake up.
-Keep your phone clean by periodically uninstalling apps that you don't use anymore and that make unnecesary use of memory, cpu and battery energy.
-Check your battery use statistics and keep an eye on applications that are using energy unefficiently, and replace them with better alternatives. Facebook and facebook messenger are clear examples.
-Some people say that connecting to 2G networks instead of 3G helps as well.
-Activate wifi at home, it seems to eat less battery than connected to 3G.
There are more tips out there, just gogle it and make a responsible use of your phone. Keeping phone clean and lowing brightness will probably make the biggest difference.
Moreover, if android S.O. is on the top of the list of battery use, your phone's software entered a weird condition. Reboot it and if it persist, consider a factory reset.
I hope this helps

I just started evaluating Juice Defender Ultimate to see if it can save battery life, but there are many options that I don't fully understand. I have attached a screenshot of the Notificatin pulldown window from my Galaxy Nexus which shows the JD status. There are 9 objects just to the right of the JD shield. They include 3 icons, 3 colored circles and 3 lines of text. Can anyone explain what each of them mean? I have checked the JD online info, without luck.
My best guess is:
the up/down icon represents mobile data
the red circle next to the up/down icon means mobile data is disabled
the radiation icon represents WiFi
the green circle next to the radiation icon means WiFi is enabled
the 3G icon represents 3g mode
the red circle next to the 3g icon means 3g is disabled and 2g is enabled
As mentioned, these are just my best guesses. I have no idea what the 3 lines of text mean?

7 ways to overcome your android battery draining problem

my own original article with original thoughts for starting my first post on xda its also on my blog
Android technology is one of the exceptional operating systems of the world. With its great embedded features its quick and loaded. Billions handsets are running on this OS these days. Right from Eclair to ICS 4.0 all are great to use android versions of OS. But with certain brilliant embedded apps like google apps i.e. gmail,gtalk and some other bundled apps like facebook,twitter and other downloaded apps it becomes a rather heavy os and uses handset battery a lot.
Though Android OS is a revolutionary one but still it has shortcomings which we think Google will certainly with its innovative perception will make it more efficient in near future. Android based handsets are mostly run on either GPRS(3G)or WiFi. They are kind of internet based OS handsets. So it requires a constant use of internet on these handsets and that makes it even a more battery draining OS. Certain applications which we download from Google Play(app store) also uses the internet and battery in background. These are mostly free apps as because these are available to you for free but developers to have to adhere a cost on it and they try to recover it from inbuilt ad packages that some times becomes annoying for us while using the app or playing the game but we have to bear with it as nothing in this worlds comes for free.
Certain issues with android OS according to me are :-
1. Applications most free applications uses battery a lot as it runs in background and that drains a battery a lot
2. Some applications require a constant gprs or wifi facility to stay updated like facebook,twitter etc. again use of constant gprs will surely drains battery 40% faster then when gprs is off.
3. Sync problem every time you add Twitter,Facebook,Gmail of other social apps it tries to sync the phone book with it thus contact list become so huge even when you try to send a message you cannot differentiate whether its a phone number or an email of the contact your are selecting thus converting it to a multimedia message(Again battery is used to a great extent)
4. Location services running in background drains battery a lot as they use gps
with all these problems android still seems promising to me as it has changed the way mobile OS used to be. It gave mobile computing a new heights, with a use of gps,3g and wifi like services in a average looking handset.
To overcome these issue i have a made a checklist which you can follow to overcome these battery draining issues in your android handset:-
1. Always turn off your location services by turning of wifi and gps in settings will make your battery's life longer than usual.
2. Turn off GPRS and WiFi when not using internet so that your battery doesn't drains out quickly as it used to be as we know the major source of battery consumption is anytime activated internet services on OS.
3. Use a good kill task app as it will kill your apps running in background so as to reduce the battery usage for example Taskman etc.
4. If you like a free version of app and game try to buy the full version of it as it will come free of annoying ads thus will reduce your battery usage to a great extent.
5. Try not to stay login onto social apps for automatic login as they will run in background to keep continuously for resumption of internet services to sync back to where you left previously. I know its a bit annoying but a good way to reduce your battery consumption
6. Try to adjust the screen brightness to a an extent it makes your phone screen optimum for your eyes don't keep the brightness to 100% as it will drain the battery much faster.(Ideal would be to keep 50%-55%).
7. Last but not the least try to fully dry out your battery and then when your phone is switched off then plugin the charger for charging as it will reduce your battery usage and increases the life of battery.
These are few of my suggestions regarding the battery draining related problems in your android based handsets. I know we all love our android devices because of their amazing capabilities and multi tasking abilities as we know every good things comes attached with certain shortcomings though we have to bear them but still it is fruitful enough to enjoy. Try my suggestion will certainly make your android experience a bit better.

Hi there,
Nice first post. It's good to see folks contributing their thoughts. I do have some comments on a few of your suggestions...

The GPS-based location service doesn't actually consume any battery power unless an app is actively polling for a location - in which case you'll see the GPS indicator in your notification bar. Just go ahead and leave GPS enabled - again, it won't drain the battery when it's not being used. Additionally, in the unfortunate event that your handset comes up missing, apps like Lookout's Plan B require GPS to be enabled in order to locate your missing device.
2. Turn off GPRS and WiFi when not using internet so that your battery doesn't drains out quickly as it used to be as we know the major source of battery consumption is anytime activated internet services on OS.

Actually, I'm guessing that the number one source of battery drain on any given device under normal usage will be the display. Similar to the GPS, the radios don't use all that much power when they're not being used. A better suggestion would be to use wifi whenever it is available, as the wifi radio is much more power efficient.
3. Use a good kill task app as it will kill your apps running in background so as to reduce the battery usage for example Taskman etc.

NO. Task managers are a no-no. They interfere with Android's built-in memory management and cause way more harm (and battery drain) than any benefit they might provide.
4. If you like a free version of app and game try to buy the full version of it as it will come free of annoying ads thus will reduce your battery usage to a great extent.

Agreed, but more so just to help support the developers that create great apps and games.
5. Try not to stay login onto social apps for automatic login as they will run in background to keep continuously for resumption of internet services to sync back to where you left previously. I know its a bit annoying but a good way to reduce your battery consumption

This is good advice. Any app/service that is constantly or frequently polling for updates will use up juice in a hurry. Many of these auto-syncing apps will have a configuration option for how frequently to poll. Try perhaps every half-hour rather than 10 minutes for email, and 3 hours rather than 1 hour for weather.
6. Try to adjust the screen brightness to a an extent it makes your phone screen optimum for your eyes don't keep the brightness to 100% as it will drain the battery much faster.(Ideal would be to keep 50%-55%).

Or you can just set it to Auto-brightness and forget it.

If you're saying here what I think you're saying, this is also a no. You should never (or at least rarely) let your device drain all the way before charging it. At least with the popular Lithium Ion batteries, "If at all possible, avoid full discharges and charge the battery more often between uses." (source)

number 4
just install adfree if you are rooted user.

But i read @ sony forum that draining to full atleast once a month and frequent charging ( wont affect battery life) will help the lasting of battery ( from the forum staff) which way we go now?

It depends on the technology of the battery, really.
And there is some benefit to fully draining an Li-Ion battery, as it helps with calibration so the OS can more accurately measure the battery's state. It's certainly not something you should do every day though.

Out of the 7 points which you have given, after reading the 2nd point, switch off the phone and throw that away, thats the best think we can do.
Everywhere , almost everywhere this is the solution given to save battery, if all features ( atlast the basic features ) are meant to be turned off, then why a Smartphone ? Nokia 1100 phone is better. I will wait for somemore time on android, and next I will defintely to switch to iOS, atleast its using the battery while we using the phone, not while sleep.

Battery

I know I've made a few posts about this in the past, but now I've learned a few things since then.
I know the battery isn't the greatest on the infuse (no rom that I'm using atm..) but would like to get the most juice out of my device that I can. I have root access and currently use the apps "battery calibration" and "no-frills CPU control" which I set my cpu at a relatively low frequency to help keep juice.
My phone is drained throughout my day, even without use. I believe it primarily happens because my data (mobile network) consumes it. I know apps such as "juice defender" are great at reducing idle drainage because it shuts off your network connection while in idle to save battery. However, I have used this application in the past and after a few days of use, it shuts off my mobile connection altogether.
My question is, if I were to use this application again and my mobile network were to malfunction, would I be able to change my apn to regain my network connection? In the past I had to reset my phone to regain connection, which isn't really worth using if that's the only solution.
Or are there any other battery saver apps worth using??

I know I've made a few posts about this in the past, but now I've learned a few things since then.
I know the battery isn't the greatest on the infuse (no rom that I'm using atm..) but would like to get the most juice out of my device that I can. I have root access and currently use the apps "battery calibration" and "no-frills CPU control" which I set my cpu at a relatively low frequency to help keep juice.
My phone is drained throughout my day, even without use. I believe it primarily happens because my data (mobile network) consumes it. I know apps such as "juice defender" are great at reducing idle drainage because it shuts off your network connection while in idle to save battery. However, I have used this application in the past and after a few days of use, it shuts off my mobile connection altogether.
My question is, if I were to use this application again and my mobile network were to malfunction, would I be able to change my apn to regain my network connection? In the past I had to reset my phone to regain connection, which isn't really worth using if that's the only solution.

A bit more information is needed before a specific course of action can be recommended. How much battery life are you using in an average 24 hour period? Also, what version of Juice Defender(beta, free, plus, ultimate) are you using, and what specific settings are you utilizing. It is a very customizable program after all. You might look into Battery Indicator Pro, which estimates your total remaining battery life based on your level of usage. I would also recommend CPU spy, which, if your device is rooted, will show the percentages that your device is running at various CPU levels.

If you turn off all the locational stuff, turn off 'update my current location' in Navigator, and set your CPU gov to conservative, you might get better battery life. I've not had any lasting luck with any of the battery saving apps. In the end, I decided to buy a couple of Anker batteries from Amazon just in case I have a bad battery day... Also some of the battery saving mods work, but I'm not sure about applying them to ICS and JB ROMS. I haven't tried!

Battery life is what you make of it..
Anything running in the background will drain the battery.. email constantly checking for new messages, twitter, Facebook, GPS, WiFi if no connection is found, etc..
Anything that makes the phone process even while the screen is off is going to kill a battery..
What ROM are you using? Some ROMs have better life than others..
How much are you actually using the phone?
What's the brightness set at?
Have you tried changing the processor and slowed it down?
Lots of information that is missing is helpful..

Some have good luck with these, others don’t. I prefer to try to adjust settings myself.

How about putting a widget on your homescreen to toggle data on/off. Keep it on only when you need it. I go a step further, I use Tasker to automatically turn my data off every time my screen times out (because that means I’m not using it... I can restart my data later with my widget when I need it). Maybe that’s extreme, but I’m not just watching my battery.. I’m managing my limited data plan.

It may be that you have wakelocks keeping your phone awake when it’s supposed to sleep. One way to see this is (in GB or above) Settings / About-Phone / Battery Use...then click on the small graph at the top... should expand it to a large graph with traces along the bottom including Awake and Screen On. If you have long periods of time where phone is awake while screen is off, that’s a wakelock problem. A good program to troubleshoot that is Better Battery Stats. If nothing else, follow the instructions in the first post in the BBS thread linked below, and then post a dump to the end of that BBS thread (the developer and a lot of other knowledgeable people follow that thread and will help you interpret results):
http://forum.xda-developers.com/showthread.php?t=1179809
Thru use of BBS, I found that Google Maps is one that was keeping mine awake and I think someone else on the forum reported the same. If that program (Maps) is causing problems, you can disable it from auto-starting on boot using Gemini Manager. It will still be available when you need it, just take a few seconds longer to load the first time after boot. Then need to reboot to stop it from causing wakelocks after use (there may be other easier ways, but this works for me).
Another program (Power Tutor) was helpful to me to see programs that were consuming unusual amount of battery although not necessarily thru wakelocks. In my case Dolphin Browser HD was occasionally drawing very high power even when that program was not actively in use.

Just to provide more details on my previous post (not sure if it's answering your question):
I followed instructions here:
http://forum.xda-developers.com/showpost.php?p=29420959&postcount=7059
In particular, I installed the free program "Gemini Apps Manager". That allows you to stop programs from auto-loading at boot.
So I used the program to stopp Google Maps from auto-loading at boot.
That stopped a large chunk of my wakelocks, as long as I don't manually launch Google Maps.
If I do manually Google Maps, then those wakelocks come back, and to get rid of them I have to reboot.
I don't use Maps that often (only when I go on trips), so it's not a big problem for me to reboot when I'm finished with my trip to help keep my battery use low.
It may also be possible to kill it from the list of applications at Settings/Applications/ManageApplications and killing botht the application and the process...but I'm not sure if it will stay killed that way... haven't tried. I know some applications have hooks that make it hard to get rid of them once they're launched.
But (if you haven't already), I think it's a good idea to use BBS to find out what programs are causing problems on your phone. You may have other apps causing lot bigger problems than Maps. And it certainly may be the case that a program that acts up on one phone can be fine on another phone due to differences in the way the user configures the application settings and the phone settings (along with other possible differences in application version, ROM used, etc etc).

Thanks for your detail explanation. My main question was how can close the app without restarting? i feel my major battery drain is from dolphin browser, befor dolphin i used opera, even that has the same problem. Most of the time, if I dont open dolphin, my phone battery is good, but once I open it, it drains battery. So i am looking for soemthing simple which does, without rebooting the device.
Any way thanks for your help.

Prevent medium power saving mode from disabling background location access?

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
