Best Battery Saving ROM/Mod/Anything?

I am on OOS 3.2.7 Stock Root Xposed.
By the time passes, the battery performance is getting fu**ed up. Its losing around 10% overnight with everything off. Earlier it was less than 5%.
Whats the best ROM/Mod/any way to improve battery performance? Even though we have Dash Charging, There is no point charging phone twice a day with moderate usage.

Use force doze? Maybe a CPU profile? Greenify? Amplify? Have you checked your wakelocks?

PowerNap, Amplify, Greenify, ForceDoze. These are the best, they helped me a lot... Also, try using the HawkPepper profile :good:

Try force doze first, I recommend you Nameless CPU profile to save some juice without performance loss

Force Doze is xposed module? Do I need custom kernel in order to use CPU profiles?

Force Doze can be used with xposed, u don't need a custom kernal for a CPU profile but I recommend it to you, anyways try and see what happends.

I am using FreedomOS with ElementalX kernel (without any profiles atm).
Used to get SoT around 3-3.5 hrs prior to flashing the ElementalX kernel, now I almost consistently get 4.5-5 Hrs SoT.
I have noticed a bit of noticeable lag while gaming but its an acceptable tradeoff for me. The kernel has some profiles that you can use with their app - I have heard people getting crazy SoTs using them.

Thanks. I just installed Force Doze. I will see how it goes.
I dont like putting all my social apps frozen though. I had RedMi Note 3G before this with same 3K battery. It used to last 1.5-2 days easily. OP3 is way better only apart the battery and Camera issues.
Thanks again!

Hmmm. I am also thinking of switching kernel. Either Elemental or Buffela. Have you tried that one?

No, sadly I haven't yet tried Boeffla. Yup sure go ahead, I have coupled it with Naptime by Francisco Franco to keep apps from causing wakelocks. The deep-sleep time is almost a flat line thanks to this app.

The kernel that comes with CM13 works reasonably well. A few things can cause excessive battery drain and its not just the kernel that is at fault. We don't know all the settings and installed apps of the people who have claimed long battery life for their phones after flashing this rom or that kernel, or even if their testing methods are reliable and can be compared with others. So any claims about long battery life is very suspect.
Google services has always had a big problem with power drain because of bugs. Google's location data gathering is not only bad for privacy but for draining power as well. And many free apps tend to use too many non-related permissions and they may misuse google play services which also drains power. So the easiest thing is install the bare minimum of google apps (start with google pico package) and use xprivacy to tighten up permissions. I think nothing can be can be done with rogue apps that use google play services.

What do you use your phone for if you don't install google play and gapps? Many people including some reputable posters liked Kairi's Xcelerate for increasing battery life but there isn't a version yet for MM. You could try the God's kernel which works with CM13 but it looks buggy from the looks of things.
I doubt any kernel (Xcelerate included) can instantly transform the redmi 1s and give it good battery life. 4-5 hours of SOT is reasonably good and believable. Claims of 12-16 hours otoh......

Should I even bother using Greenify?

I used to use Greenify when I had my Xperia Z3, but I don't know if I should keep it on my 5T, and if it affects performance or not (ex. reopening apps draining more battery or apps taking more time to open).
I have the 8 GB model, so I don't have any RAM problem.

Lately I've decided to try not using any battery "optimizer". I'm currently on OOS B2 with Flash Kernel 3.0..1 and I can easily get nearly two days if battery life with a "normal" use with around 4hrs of screen on time and 1~1.5% per hour while on idle overnight.
So, I think that overall that's not worth messing with Greenify. IMHO
About performances, in theory having to relaunch apps that have been terminated by Greenify would have some inpact on that. Guess that would be quite low, being the device so fast!
My advice would be see how it goes as it is and then try installing Greenify and see if you notice any improvement.
My two cents.
M!

Greenify only hibernate apps, not terminate.

I use Greenify for Facebook and Messenger as they drain a lot of power. I would simply check your battery stats if there are apps that use a lot of power without active usage. If so, Greenify then. If not, it probably doesn't make a huge difference.

Greenify is no matter what, a must download app for me.. Until V30+ and OP5T.. Didn't need it anymore, because I didn't notice a different between installed it and not..

This is an easy one. No.

Deep sleep and idle battery drain seem pretty good on the OP5T so far, I wouldn't bother.

I still use it, nothing related to performance but because I personally do not need some of my apps to run in background. I only use them when I open them so I can save a bit of battery by keeping them hibernated until the next use.

As long as I have good cell signal, I can routinely get 8hrs of SoT with the stock One plus kernel from OpenBeta2. I do use Greenify for the social media apps though. Greenify will basically tell you if it will help or not by displaying apps that it thinks will benefit from hibernating. Although, if you aren't rooted, it basically isn't worth installing.

I'm just asking because I use Amplify, Greenify and Android's built-in battery saver and Android OS still drains A LOT, and by a lot I mean that I can get 3 hours SoT with amoled themes on.

Upgraded to Android 10, garbage battery life

Hi,
I flashed stock android 10 image after it was released a few days ago and the battery life is GARBAGE. Any ideas on how to fix this? I know adaptive means it should get better after a few days, but I don't really see this.

Battery life for me is pretty horrible, I can't get 2 hours of screen time doing simple things like taking photos, reading the news and email and some book reading. I don't even play games, I would say processing of HDR photos is the most intense thing I've done. I updated on Tuesday and battery life has not improved.

I had the same terrible battery experience with android 10 stock until I changed kernels. Assuming you are rooted, you can install Ex Kernel Manager, then go to the ElementalX tab and click to check for update and it will give you the option to download and flash Elemental X v. 5.05 for pixel xl android 10. It will flash the new kernel for you and then ask if you would like to reboot. Once you reboot you can change governors and many kernel settings. Currently I am at 54% with over 3hrs screen on time and average about 15 hours per charge with 6 or more hours screen on time. This is at least double what I was getting on the stock kernel.

Actually, even if I do apply on boot, is resetting governor to sched. Hmm

I don't see a real battery difference switching to powersave, just a performance difference.
I didn't actually switch the kernel, though. That's with the included kernel.
The battery life really is awful. Any ideas?

Changed to Elemental.
Set governors to Elemental.
NO improvement in battery.

here are my settings on Elemental. *note under cpu, I have to manually disable perfd after every reboot as the setting doesn't stick but everything else where the apply on reboot is highlighted works automatically. Battery is noticibly better with perfd and core control disabled.

That's awesome! but, does it have significant impact on performance compared to stock kernel? I'd like to balance out performance and battery life.

I wiped the phone and installed 10.
No improvement with battery.
Also, now I have the problem of my messaging and email apps don't update unless I manually open them. and sensor seems to be messed up to where if you tap twice on phone, you don't see clock, and picking up phone doesn't show notifications, despite these options being turned on. I know there is a bug on this.

For what it's worth, I was on the Q betas, and battery life was similar to what I was getting on pie. Then once the official update installed, battery went to garbage even after several days. I ended up downgrading to Oreo leaving the bootloader unlocked, but installing elemental x kernel so that I'd still pass safety net. I had heard before that Oreo had better battery life than pie.
Things improved after that, but I know that a downgrade like this won't be an option for most people.
Edit: also should mention that I've underclocked the CPU using the installer for the ex kernel which has also given me a slight boost in battery life. Don't really notice any performance difference for my usage.

I used ex kernel manager to flash it and then rebooted but it's a paid app. for a free app you could try flashify which is an app that can flash kernels and recoveries. I haven't used it in a long time to flash a kernel so I make no guarantees but it has worked well for me in the past.

How much did you underclock? I went back to 8.1 and battery life is much improved.

Stock seems fine to me 6hr sot on lte off charger for 17 hr. But did replace battery a year ago

Hey, I assume you're asking me. I underclocked to 1440 for the small cores (down from 1593), and 1900 for the big cores (down from stock 2150). The aroma installer has a few values to choose from, so you can try experimenting a bit. The values I used represent about a 10% drop from stock speeds.

The biggest battery drain I have is keeping WiFi on. So I created some tasker profiles to turn off WiFi 2 minutes after the screen goes off, and back on when the screen goes on. It also only turns off if it's not plugged in. Still not perfect, but works well enough for me.

Horrible battery life all of a sudden on 10.0.7

It's due to OnePlus brain service. Search in the forum for it and you'll find a couple of ways to stop it.

thanks. Seems like that is very hard to do. I might just disable the custom kernel. Honestly the only reason I installed it was so that I could change the vibration intensity. If anyone knows of another way to do that outside of custom kernel manager I would be all for it!

I also have ExKernelManager with default kernel because it fixed my WiFi issue and the phone sleeps as a baby at night.

sounds like the issue is probably the kernel then. Im going to just go back to stock I think

As I read in the forum it is related to oos version 1.0.0.3 and oos 1.0.0.7 and not kernel related.
I flashed the fix mentioned in the thread but no luck for me. Cluster 3 remains on 2999 MHZ and CPU tmp still on 50+.
Seems flashing to build 1.0.0.6 is the only way to fix this issue.
Edit: I just set the max CPU from cluster 3 to lowest settings and the CPU dropped right away and temp is now steady around 30/35 degrees. For me a temporary solution till next oos update.
Regards ysco..

I got the same issue. Getting not even 2h SOT. No custom kernel here, just basic OS with darkmode on & on WIFI connection.
(Currently 1:28h screen usage at 29% battery left)
Any fix in sight for this?

Phone is almost unusable for me now with such crappy battery life

Just install arter97 kernel, worked for me and clusters are running nicely now and CPU temp is low.
Battery life is improved now because cluster 3 is not hanging on 2999mhz anymore.
Just download the kernel from here https://forum.xda-developers.com/on...development/arter97-kernel-oneplus-7-t3952578
Just flash in your favorite kernel manager the new kernel, magisk will be preserved. First boot takes some time after flashed the kernel.

Glad it also worked for you to.
Well i was testing and reading on the forums about the drain because I only got two hours of Sot because of cluster issue. And started testing different kernels and this one fixed everything and is my daily kernel now. Battery is improved with 90% now I have almost 3 hours Sot and 70% battery left on the first run after installing this kernel.
Regards ysco..

Just a update with the used kernel I discribed earlier.
7 hour Sot and 10% left, never had such good battery on my former oneplus devices then I have on the 7t now. So no issues anymore with battery drain.
