I had seen one too many posts about people asking and complaining about battery drain issues on their G1 phones and it gets tiring to read it every 5-10 posts. So I decided to create this thinktank to pool in ideas from the community and create a set of best practices to maximize mileage of our phones. I'm currently using a HTC Dream with stock battery and my battery life is pretty good with light to medium usage. I would like to contribute to the community by creating this thinktank thread. I hope this can help as a guide for myself and for people who have been having numerous battery drain issues on 5.0.7-DS and variants of this distribution.
This is NOT the ultimate end-all solution for your battery problems. These are just steps to tackle the problem. If you want minimum to no battery drain keep it plugged to socket or plug it in a car battery.
If you would like to contribute your experience, or make any corrections please do not hesitate to post and I'll include them if they seem fit and attach your name as reference. I'll also do my best to give credit where credit is due. Please see the references at the bottom part of the post. Please do not clutter this thread by doing "I'll try this" or "It doesnt work" post. Its more important for all of us to know WHY it work/didnt work. Stick to topic, and be constructive. Be intelligent. Think first.
0. Update your Radio
Updating your G1's radio to the currently-latest version (2.22.23.02) should give you better battery life as well as signal reception (you can always switch back to 2.22.19.26I if it doesn't work out for you)
1. Recalibrate
Take note that BATTERY STATS ARE WIPED whenever you flash a new rom. (since full wipes are required whenever changing ROMS, and /data is where the battery info is.) This usually leads to inaccurate battery readings.
Here's how you recalibrate properly:
- Charge your phone till the GREEN LED shows up. Leave it for another hour.
- While plugged, go to recovery and wipe your battery stats.
- Right after the phone is booted up and settled, unplug and use as per normal till it shuts off. Then charge as per normal.
2. Disabling some basic phone hardware functionality
Turn off GPS, WIFI when not in use. And brightness set to manageable levels. Even loudspeaker. This is self-explanatory. Automation software like LOCALE can be useful, but usually all it takes for you to turn off your ringer, or turn on wifi when you're at a specific area is just a press on the Power control widget.
3. Overclocked kernels
Running on full overclock speed (by default is 528mhz or even higher on some kernels) will drain your battery faster and you'll notice significant heat increase when you're using your phone along with 3G.
Although im using pershoots 576mhz overclock kernel, I do not max it to 576 unless needed. The reason why I use his kernel is due to its UNDERVOLT capability. I have set up my phone using SetCPU
MAXFREQ: 480,
MINFREQ: 176
CPU Governor : ONDEMAND.

Usually I would set my phone to 384mhz if im going to stay on it longer (texting/long browsing etc). On the sleep mode I set it to 122mhz to 384mhz.
4. Tame your widgets, minimize using them.
Widgets that constantly connect to the internet, or constantly refreshing on the screen to update data being shown on the screen at extremely small intervals would also give you battery drain. Minimizing widgets can help minimize applications running in the background (free up memory) and avoiding your phone going on "partial sleep". Also tweak your widgets to update as less as manageably possible. If for some reason you can't see the next suggestion.
Aside from that you might want to disable Background syncing and do manual syncing. Aside from saving your data plan, it also saves battery life. You can disable it by doing the following:
Menu > Settings > Accounts & Sync > Background Data - OFF
Click to expand...
Click to collapse
manually update your facebook widget or contacts/gmail by
Menu > Accounts & Sync > Facebook (or GMail) > Sync.
Click to expand...
Click to collapse
5. 3G, 2G, switch off, or automate it.
You'll notice that inside the default settings for mobile networks. Setting to 2G will "save battery" which is actually true. The connection will definitely be slower, but if you like your phone to last longer throughout the day, either switch to 2G or turn it off altogether.
Also, similar to juice defender, I use 2g/3g toggle and toggle data as and when needed.
Another suggestion that I just found out recently is the use of Juice Defender app [d]. It automatically turns on or off your APN settings at intervals. You might want to try to look at that app if you cannot do #4
6. Disable live wallpapers. Auto Updating Sense
Remember that 2.1 isnt actually built for our old phones. and livewallpapers do require cpu/gpu processes. These are also running in the background and may run while your phone is asleep. So turning them off will benefit you.
7. Refrain from using Automated task killers and choose what you kill.
If you see that the app you had been trying to kill a few times keeps coming back. Stop killing it. Everytime you do, and whenever it respawns, CPU flies to 100%. Go back to #4.
8. Disable Market notifications.
- Open the Market application.
- Select the Menu key.
- Select Downloads.
- Select the Menu key again.
- Select Notifications.
- Select the Do not notify me radio button. press [Ok]
Click to expand...
Click to collapse
9. Make your phone sleep.
Open your spareparts application, Go to End button behavior. Select "Go to sleep"
10. Under the hood tweaks
10.1 Extending Wifi scan intervals
Edit the wifi scan interval in /system/build.sapphire.prop (or build.trout.prop if you have a G1)
# Time between scans in seconds. Keep it high to minimize battery drain.
# This only affects the case in which there are remembered access points,
# but none are in range.
wifi.supplicant_scan_interval = 45
Click to expand...
Click to collapse
Changing this number to just 90 second will half your wifi scans. Obviously larger numbers can mean less wifi scans which means more battery life, though it may take a little longer for your phone to pick up a remembered access point when in range. This is not just a CM/Eclair thing, it can also work for Donut phones.
This setting needs a reboot after editing the file. Edit it with Root Explorer, or nano as root if you have CM5, or pull the file with adb then edit it then push it back.
11. Remove your phone from your pocket whenever you can.
Body heat deteriorates battery life no kidding! there had been already studies to back it. I keep my phone either on my hand or outside of my pocket to keep it cool. Do whatever is manageable in your environment. If you're using your phone as a music player streaming using streamfurious and stuff. dont let your body heat add to the heat already been generated by your phone itself.

really? isnt warmth charging batterys? in my old gameboy years i always put my batteries on the heater when the drained completely and after an hour i could play again with the old batteries.
1. Recalibrate [a]
Take note NOT TO WIPE BATTERY STATS whenever you flash a new rom and your battery is less than 90%. This usually leads to inaccurate battery readings. If you already wiped your battery during one of your flashes, here's how you recalibrate properly:
- Charge your phone till the GREEN LED shows up. Leave it for another hour.
- While plugged, go to recovery and wipe your battery stats.
- Right after the phone is booted up and settled, unplug and use as per normal till it shuts off. Then charge as per normal.

This is true, but since battery stats are stored on the data partition, a data wipe also deletes the battery stats. A lot of rom's require a full wipe, meaning data and dalvik, so battery stats are deleted whether you select the option or not.

Hi!
Yes Im very familiar with that practice because i do that too. The reason might be because of the composition of the battery (alkaline, non alkaline). Usually we put it under the sun so that the heat will help change the composition of the compound inside the battery in order for it to lower down its resistance. Leading to a "charge".
But now we are using Li-Ion batteries, and I do not suggest putting them under the sun because it will deteriorate your battery capacity holding charge and its lifecycle.

how about going to setting - about phone - battery use?
there you can find out exactly whats killing your battery and take appropiate action.
Also, similar to juice defender, I use 2g/3g toggle and toggel data as and when needed. Using these two widgets i have no battery issues.

change preferred network type helped for me increasing battery life
Hello all,
as describe in post
forum.xda-developers.com/showpost.php?p=6432560&postcount=1
changing preferred network type worked for me.
default setting: WCDMA preferred drains my battery in a few hours, crazy
within CM 5.0.7-test7 I was able to change to: GSM/CDMA auto and it worked
But now in the final release 5.0.7-DS I can not select this setting. Perhaps it correlates to the this (PRL) info in brackets.
It seems that no "auto" setting want be working so I am trying WCDMA only right now and will see if I have a network in 2G networks too.
Bye morT
Hhmm let me think…
Running a prrocessor that's massively overclocked with software that was never meant to run on our g1's I have an idea.
****** off back to stock or get over it
I mean seriously people come on, we have set cpu for power profile management, basic battery usage which is dim screen, turn off wifi and 3g when not in use blah blah blah same **** written in every guide about battery life for ANY roms from cupcake to eclair.
As I said, get over it or go back to stock.
[highlight]Mod Edit: Please watch your language and don't flame others.[/highlight]
im sorry does turning on "display battery status" in spare parts still effect battery life? TIA
Ive noticed that bluetooth is killlllling battery life, but dont know if its normal. I charged to 100% and turned everything on, leaving screen on the whole time and what not.
While I was actively using the net over WiFi, I had nothing using the bluetooth, and both seem to eat up 20%..
This might be normal, might not be, but thought it was odd that it being on, but not in use, ate up just as much as functioning, in use, wifi.
whats funny to me is as soon as my phone dies i plug it up reboot it a few times and my battery is at 70%
.... i think its not reading correctly .. i mean fully charged play talk text browse till it shuts off .. plug it in turn it right back on then reboot ..
and my battery is back at 70% which is weird ... anyone else notice that???
also wifi, gps is on screen brightness is standard !!!
batteries really seem to be the least developed technology in our high tech phones. feels like a sportscar with a one gallon tank...the fun's over quickly...
turned off my 3G and got a lot of additional battery life. with bad 3G reception (like in the place I live in) the phone was sometimes sucked empty in just a few hours, now I get two days.
another thing that really helped me extend my battery life was turning on airplane mode when I went to bed.
how about dont use overclock or any other cpu speed up tool....maybe the speed they are factory set to is there for a reason...Hmmmmmmm

You should go through a battery recalibration - steps on the first page.
Best Practices for Improving Battery Life for CM 5.0.7 (and variant ROMS) is to use this ROM, Thanks.
Do whatever you like, show or hide battery status in the Spare parts, calibrate or not....the battery remains....for loOng....enough time....

Since I have a background in electrical theory and chemistry, let me end this debate once and for all: heat makes atoms (and therefore molecules) move faster. Lack of heat (cold) makes them move slower. In general, fast-moving atoms in batteries mean MORE power, not less. The reason your car doesn't want to start when temperatures are subzero is that the battery acid (electrolyte) molecules are moving too slowly to oxidize (give off e-, electrons) and turn back into positive ions. The same is true for the ol' Gameboy AAs -- put them on the heater, the dry cell warm up, and more electrons are transferred to the anode by anions, the positive ions (cations) are more able to travel to travel back to the cathode (in the case of dry/wet-cell rechargeable storage batteries). Heat acts as a catalyst to produce electricity. Some of you may have even taken your car battery indoors if the electrolyte froze in the winter. Some of your cars may have battery blankets or even battery heaters if you live really far up north. In addition, the process of charging a Li-Ion, Ni-mH, or even lead acid battery will produce heat, because chemical conversion is bi-directional, but anyway . . . you charge the G1, it gets hot. You use it heavily, it gets hot. You know you're spending electrons somewhere when it gets hot period. Keeping the phone cool will not increase battery life or make it charge fast. What lower battery temperatures will do is lengthen the battery's overall life. What happens if you leave meat out in 100F/30C temperatures? It goes bad quickly. Same principle in Li-ion. The rechargeable battery is ideally an efficient, closed system of ion exchange that should work for many (hundreds) of duty cycles, but eventually heat plays a role in deterioration of the electrolyte and chemical catalysts inside.
So put your extra charged batteries (but you don't want a Li-ion or Ni-mH battery to sit very long in an discharged state, so be careful here) in the refrigerator in an airtight bag (rotating on a daily basis) if you really want them to last a long time, but don't charge them frozen (ka-boom!) and remember cold batteries charge slowly. Car batteries in sub-tropical areas are replaced at a rate of about once every 24 months, but in Sweden? Maybe every five or six years. Cold temperatures slow down chemical deterioration just like cold keeps that steak from becoming maggot food.
Again, a hot G1 may weaken its own internal components and batteries over time, but putting it on ice won't give you an extra 6 hours to oogle Miley Cyrus' vBlog
Hope this helps.
For me, unless I'm expecting a text or a call always have my phone on airplane mode. I turn it off every hour or so to see if I got any unimportant texts, and then turn it back on
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
Sent from my Milestone XT720 using XDA App
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.
u da maaan dude, thanks for a very detailed and informative article
Just a question for those who having the same problem with me, please share your opinion.
Green power premium vs JuiceDefender Ultimate vs Power Max
i'm stuck on this 3, any of you have better idea which is the best for battery?
i tried JuiceDefender Ultimate before and i'm not really satisfied with the result. Please note, i'm running Exchange email for daily use and required data connections.

Don't use any of them. They all consume your battery.
Try this:
Set your display brightness to auto or dimmest. This usually consume the most of your battery.
Download a data switch widget or toggle from the market. I use the dataswitch from tomatoX. Turn off your background data when you dont use it. Turn it off at night or sleeping.
Turn off your gps or wifi when you dont use it.
If you are rooted, you can also edit your build.prop wifi scan intervals to higher number (for ex: 120)
You will find by applying some of these changes, you will extend your battery life.
have fun
I also find that using ROM Toolbox to Disable some apps that start up on boot helps too. Google Maps is a battery killer for me (at least thats what I find) it seemed to start up on boot and eat all my battery so I disabled it.
You might find disabling a few more useless apps helps too.

Just curious if you've actually tried these for yourself or if you're just quoting "common knowledge"? The reason I say this is I've been using Green power for about 6 months now and it gives me a noticable improvement in battery life. Yes, I know I can manually turn off wifi and/or data when i know I won't need it, but green power does that for me automatically. I tried juicedefender for a little and didn't really like it, and I've never used the third choice. Green Power has the best free option that I've seen, it gives you full functionality while Juicedefender free is a limited function app. And if you're wondering yes I've tested my phone both with and without green power enabled, several times. Each time results are the same, at least a few hours extra time at worst and at best it's nearly doubled my usage time.

Here was my original post...I do use it daily

recheck the thread.
Not really sure what you're saying to me? You give good suggestions in you're first post, my point is that using green power will do all that for you automatically and definitely does not use more battery power.

if that works for you, then that's fine.
green power is loaded into memory and may actually consume battery as it is running in the back ground.
my point is that many programs with data syncs are unknowingly shorten your usage per charge.
turn off your back ground data..saves data and battery usage.
try this: use your green power for a few days..see how long it lasts
then try the dataswitch on the green power and without the green power and see what it does...
carry a spare battery also works
Hi
First of all I'm back on Android and back on the forum after four years of iOS, really enjoying Android and the forum again!
I just got my Z3 for about 2 weeks now and I'm not getting the 2days out of my single charge, when I take the charger out at about 7 in the morning, I'm left with about 30-40% at 11 a'clock at night. I'm just wonderring if these 2 days should be able to reach with heavy whatsapp usage (groups, really almost receiving a couple of messages a minute ) and moderate Facebook, Snapchat, browsing, and maybe some app downloads? Are there some settings you guys recommend to increase battery life? (already using stamina, doesn't really make a big difference).
Thanks in advance!
You can follow the battery life thread.
I have autosync, location and WiFi calling enabled and I still get 6-9 hours of screen time out of a 24 hr period with heavy usage with or without WiFi calling. At first I got no more than 5-6 Hrs screen time but as I used it and it settled/calibrated it got better.
Whats your signal strength like? It can have a big impact.
As for battery saving tips:
Try turning off or reducing the nunber of apps syncing. Facebook can also be a killer at times, I disabled, I barely use it and when I do need to I just use the mobile site.
Also turn off background WiFi scanning and set the following option -> WiFi off when screen off or on w/screen off only when connected to power.
Lastly try calibrating the battery as even Apple as you probably know reccomends for their devices:
1. Full drain
2. Full uninteruppted charge
3. Discharge with regular use to 0-1%
4. Full charge and use normally
As for stamina its not done anything for me either so I disabled it. More like placebo effect lol, I think they will fix it.

Thank you for quick response!
I've searched for a battery life thread but I couldn't find one, where can I find it?
My signal strength most of the time has all the bars, except at my house I have only one or two bars in various rooms, I didn't know about its big impact so this might indeed be a reason for my battery drain. Turned off almost all the syncing for my apps, and did the WiFi settings you mentioned, if the setting 'WiFi off when screen off" is enabled should my WiFi be of when I light up the screen without unlocking my phone or just really when the screen is off? Thanks for the tips, I hope I can get more hours out of it now!
At some time I had a short battery too and after those same steps I have 3 days battery without any problem:

The battery thread is in "General" its called "Battery Life is Insane".
Hey all,
I bought an S22 Ultra a few months ago and was disappointed with the battery life I got, even after I waited fo Adaptive battery to kick in. I expected a hell a lot more with a 4nm chip and more efficient LTPO Adaptive refresh display. So, I did some investigation and I think the main culprit it background services hogging battery. I tried out a few settings and finally found the following 2 steps to help me drastically improve my standby drain and battery life. Thought, I'd share them here, so anyone else who has terrible battery from the S22 series could try this out to improve their battery life.
Here is what I did;
1. In the Developer options, there's an option called "Suspend execution for cached apps". Please enable this! We all have to accept that Samsung devices have a lot of services running in background which hog the battery and all poorly optimized for efficiency. As some other posts have claimed this setting just shuts off all unnecessary nonsense running in the background. After enabling this setting, my standby drain is incredibly minimal (about 2% overnight, utit used to be 6% or more). I still get notifications from messenger apps (see next step).
2. In "Background usage limits", put all rarely used apps to Deep sleep or even just sleep. Here, make sure to put all your messenger apps to never sleeping to get notifications.
NOTE: I don't see any performance hit with the suspend cached app setting. Adaptive battery should actually do this (in a less obtrusive way) , but for some reason doesn't work as good this setting in disabling background usage. If anyone cares to explain this, I'm all ears
Do you keep adaptive battery on

Yes. I have left it on. When I disabled it, I got slightly worse battery life. But, the game changer is suspending cached execution. I see immense difference after enabling it
One thing I don't understand is, in Android 12/13, if we put apps to Deep sleep and keep adaptive battery on, I don't know if this will affect the Deep sleep configuration

I find it better off personally adaptive battery
подскажите этот метод кому помог в плане автономности?
anyone else test it?
phone apps works fine with option Suspend execution for cached apps?

Yes, phone apps works fine.
I followed this stopping cached apps since 10 am, it is now 7 pm, so far, so good, all notifications ok, no delays
I'm testing this now, I'll update tomorrow with any results.
always start with DEBLOAT

I am testing this right now, and after almost 1 day of ussage, i think that battery has improoved quite a bit.
18h 28min usage, out of that 4h SOT, and i have 37% left battery. , so thanks for this. One more thing that i did is, i turned off RAM plus. I think 12 GB of RAM is enough.
Hello, can someone tell me how to disable RAM plus? I want to test if this improves battery, but can't see an option to disable it, only to select how much RAM you want to assign. I'm in Android 12, still waiting the update. Many thanks.
I just turned it on, lets see what happens.

See for adb command
Disable Samsung RAM Plus
Android Police has an article on how to disable Samsung RAM Plus if you're still one OneUI 4.x. In the beta for OneUI 5, the option is there but it's not in v4. RAM Plus allows you to allocate a portion of your phone's storage to act as virtual...

Tested it for a bout a week, battery is a bit better, but in some cases system UI gets unresponssive or totaly lags out. Would not recommend this option as it is not stable. Also in some calls people didnt hear me, so I had to repeat the call, than it would work fine.
Tried it for a few days and went back to the default setting. Phone performs better in default setting for me. Battery life was never an issue for me either.
