which rom for oneplus 3 has best battery life and performance

Please tell me which rom is overall gud for oneplus 3. Checking all the rom ia not possible for me it takes lot of time and i m really disappointed form oxygen os 4.0.3 it drain lots of battery please suggest me a rom with good battery life and performance i dont care much about customization

Iam afraid there is really nothing that can help you (or others like me..). I have tried allot of ROMS and they all result in somewhat the same result.
1 charge 1 day (or almost 1 day) Does not matter if i use custom kernel battery improvement tools or "special" tips and tricks at the end of the afternoon iam still running low. I know i use my phone ALLOT and i use allot of connectivity (WIFI, 3/4G, BT) that is properly the issue, but still its sad that the only thing that might help is buying the oneplus3T.

If you want to stick to MM then go for Sultan's CM & if you want to upgrade to N then go for Resurrection Remix. Both ROM's stock kernels have new good battery life but in the camera part they are out numbered. Sultanxda has done best job by optimising the inbuilt camera app at par with stock OOS & also he gives security patch updates too as soon as they are released.
Resurrection Remix on other hand works great with Android N but has buggy camera due to buggy camera on LOS & we know that till now OnePlus has not released blobs so can't do anything.
All this is my personal preference. You can try out both our any other ROM's from development section like Cypheros or AOSP extended which are AOSP & LOS based or for for Freedom OS or Experience ROM which are OOS based.

I have around 7h SOT with latest freedomOS and bluspark kernel. In my eyes thats pretty good and carries me easily through the day. And light use even 2 days.
If you have any heavy battery drain you should search for the reason. Check wakelocks and logcat too find out whats wrong.

Try VertexOS.. You wont feel a stutter and I'm not joking.. Als it scales way more efficient because of EAS. It delivers a near stock experience

Well it has EAS.. Which means that the CPU can be really tamed.. Battery depends on standby but in my usage pattern I can easily get 4 hours SOT. I get an average drain of 13% per hour.

Great Battery on LOS Nougat roms!! :)

Hey folks. I'm sharing something nice i've been using for a week that I am very happy with.
First of all, I'm a humble guy and I'm not into coding like many respectable members from here are.
Since I changed to Los based ROM ( ressurection remix + dragonxia kernel- thanks to pappschlumpf, the only complaint I had was the battery. With MIUI ROMs battery used to last a lot ( at costs of performance and limited multitasking, I must say), and this was a nice Thing
After googling a little bit, I found out on XDA another thread belonging to people who uses the OP3 smartphone. On that thread they've created a project called AKT that states for advanced kernel tweaks.
So thing is, those tweaks were first released for snapdragon 820 processor, but latest versions supports tweaks on our Chipset (snapdragon 821). Using the instructions on the thread I was able to get a good battery with consistent performance ( need more time to quantify - I'm using zana balanced profile), much better comparing to stock settings. Its also good to remember that not all settings are applied because of the limitations of the kernel..
So here is the link:
:cyclops:
https://forum.xda-developers.com/oneplus-3/how-to/advanced-interactive-governor-tweaks-t3476589
Hope it helps you if you were having the same problems as I was, any other suggestions are also welcome
Screenshots with battery profile "fusion conservative"

Been using Ghostpepper from that thread for a while now, works great on both Lineage/RR and MIUI. Good stuff!

Hey. Can you just describe 'Great battery' with farther information(or proof) like how much Screen on Time(from 100 percentage to end), total battery life, used apps during the session etc? Saying just 'Great battery' doesn't mean a lot though. Thanks.

I know that app for a while, didn't try it yet though. I just wonder what does 'Great battery' mean for anyone who puts it into word. It means +9H SOT over a day for me, which I actually get.
Im sure there would be a difference but that wasn't the point of my post.

I agree with you my friend, and I think the more suitable world to describe it would be "better"
Since this is the first week im using AKT, im running some tests and varying many of the profiles on my daily smartphone use, so my battery levels aren't consistent to a fixed kind of profile
Anyway, As other user said, if you are on a LOS ROM you will notice how battery drain is very high. If you try it you will see the difference, and I think it's worth trying since it's free..

Here are some screens of my battery life. Used battery (ZHANA)profile in akt app. And 15% performance profile to play mupen64 games.
So u see batterylife is amazing in my opinion. And still have 20% left
I think the phone would make 18Hours battery with one charge.

I dont use any battery saver stuff, only Mi's background restriction. And Im using my device with 9 active xposed modules, live status bar indicators, live widgets and wallpaper, lots of app including two or three games like RR3, brightness %60+ under the daylight, low 4G signal+wifi(Smart radio switch when screen is off) and here is what I get(sometimes):

That's very nice results, but:
1) Do you have problems with notifications on this MIUI rom(like messages not arriving at the real time when the phone is on standby)?
3) Do You also keep GPS ON?
2) Have you tried a LOS ROM?

Thanks,
1. Since background activity is restricted; nothing comes in background. Besides; I always disable whole notifications, led, for all those apps. I only check them when i want lol.
2. Yes, I've tried LOS for 15 minutes then returned to miui immediately.
3. I use navigation sometimes, it reduces SOT remarkably, that's why i keep it off when it's not needed.

I am trying up this tweaks on RR from today. Let's see how it goes. So far best battery on a LOS based rom I had with AICP, and still nothing approaches EPIC rom, especially the latest marshmallow build.

I would even ignore if the battery would worse on Los, or RR though. I don't really care battery life since i've got a secondary device on my pocket. The deal breaker is Xposed all alone [emoji1] Dammit I can't stand without my status bar set up, not even for a day to test Nougats.

Hey, I got it and I agree with you, the best battery of this device is from MM MIUI.. But still you are keeping notifications not delivering properly and keeping GPS OFF.
Its a personal taste of course, but On LOS ROMS this phone is almost perfect, as another user mentioned here. On MIUI I had many problems about my notifications ( I didn't receive them without a significant delay) and with multitasking options, even disabling the tweaks to save battery.
Not to mention that MIUI is not customizable as LOS..
As I agree with the other user, this phone is a BEAST with LOS ROMS..
The only problem with LOS roms I had was the battery and the camera ( yea the camera has a better consistence on point-and-shoot mode on miui).
With this mod, battery is very good and acceptable, WITH GPS ON AND LTE ON AS WELL. For me, so far, it's lasting more than 12 hours with around 3:30 sot, LTE on and GPS on, and that's great :laugh:
I think we'll have the best battery and performance when xiaomi releases official release nougat for our device

Side note; my all day Gps on for Navigation, Lte on usage was like over 5H sot/14H total. Damn tough battery though. My first Xiaomi device but I've been using Miui on my previous devices. I will keep miui on it until frickin xposed shows up for Nougat. Ps. Never flashed a Miui nougat rom yet

Konstantine, everyone understand that the battery is BETTER on MIUI ROMS. No discussion about it. What I'm talking about is a good battery that can last a Day with GPS, LTE on all the time, with no battery saving apps ( or background data restrictions), ON LOS roms. LOS ROMS .
If you use it on miui, I really don't know the results, but I think the battery WONT BE BETTER THAN IT ALREADY IS on miui Roms ( most specifically epic rom), if you use this mod
So, If you ever plan to try LOS roms, give this mod a try, it's nice.

Total of 4 hours of screen on time is 4 hours ?
Also check what apps you use mostly which is highest in battery consumption list.
4 hours SOT (screen on time) isn't bad if it's for playing heavy duty gaming like PubG or such. Same setup would offer higher SoT if used others daily used apps like social and videos.

Have you checked in your battery stats as what is eating do much of battery?
That usually points to the culprit.
Otherwise, you can change kernel to a more battery friendly one.
Yes, 90 mins PubG for 100-0% is indeed low, unless your battery has degraded hardwarely

Try using different kernel. Select one which is known for better battery backup over performance and try that to see if that helps to get more backup.

In the ROM section here.
I don't use that ROM so I am unable to comment which kernel would give you best results, it's more like Trial n Error type testing you may have to do.
Allow a kernel to run for couple of days before coming to any conclusions about its true potential.
If nothing helps I guess time to try out a different ROM

Once again tough question since the Custom ROM is meant to satisfy different need of different people. Some wants PubG over anything else. Some wants performance of UI.
More or less all ROMs are good but all have different short comings.
Chose a ROM which is officially supported here and widely used. Unlike your present ROM, which seems to be not supported anymore. This helps to obtain assistance when something isn't in order.
Start with Pixel Experience ROM. Performance, integration, fluid nature of operation is mind blowing. I personally had issue with battery drain when idle (SOT was fine, like 5+ hours with mixed use). AR Beast kernel solve it a bit.
Pixel default with anything mode was drinking 2.5% to 3% battery per hour but after I installed AR Beast, it was down to 1% or even lower per hour when idle like night time.
Some other users have different setup, like @$Ayush$ is running,
PE ROM + AR Beast kernel + Sun Cooling
Then @Rahil4321 is running following setup,
PE + Heliox V2 kernel + Boost v7 + Uber Cooling
Then @sanjay.2704 is running following,
PE with heliox 2 with akt project xana balanced
So if you chose to try it out, check that ROM section and start with the ROM first, after couple of days depending on your need chose a setup by asking there. As those individuals can comment about their setup, how or why.
I am presently running AiCP 13.1 may 4th build (latest one). No extra modification or kernel or any such. Performance is some what satisfactory, things are working fine. By things, I mean most of the stuff I use in daily life.
But pixel was by the smoothest ROM I have used. So start there. Couple of issues that I faced with it was as wrote above, battery drainage in idle (others have solved it with different setup), then WiFi link limited to 72 Mbps (AEX/AiCP/ZUI i see connecting at 150 Mbps) last of all the Jio reception (but all custom ROM I have used have this network bar fluctuation issue) issue, but never faced call drops.

That was actually helpful. Thank you..

DotOS
I was also previously using CitrusCAF 3.6 as it gave best battery life. But in last month or so, battery drainage became very common. Even on clean installation.
I have currently settled on DotOS Oreo after trying AEX5.5 and RR. AEX gave me 4hr+ SOT. But DotOS gives around 6-7hr+ SOT.
I am a moderate user. No bugs so far and smooth.

Going from Oreo to Marshmallow & Battery??????

hello there, been following this forum for ages, and a owner of a htc 10 for two weeks....
But I have a big problem....... the battery.....It really is abysmal......
I am currently on LeeDroid oreo, but have tried other roms, and come to the conclusion, the battery sucks!
I know there are kernal tweaks, but with this phone, i just like running the basic custom rom, no bells and whistles......
i am s-off and know how to downgrade/sort signal out/CID/ADB and everything, but I am reluctant to go too far back (Although I do like marshmallow)
I know on other phones, that going back to a previous firmware...sometimes improves the battery
but will it improve my battery????????

I went from Oreo to Nougat. Battery much improved. I was running pure stock rooted. No other mods on Nougat. Took a day to settle, but I could finally leave the house not worrying if I needed to carry a USB cable with me for a charge.

And overnight, do you notice any abnormal discharge? As much as 25/30%? or less?
I have this much of a discharge on nougat and on oreo... Did not noticed much of a difference on both FW tbh... As i bought this phone 2nd hand about a month ago, it was already on N and never tested it on MM to tell if there is any difference.
Our luck is the fast charge capability this phone has...

I would say so, yes I had problems. I bought this phone 2nd hand as well. A mint Red one. Pristine condition - at least in appearance. I also have/coming from a daily driver LG V20. Which also uses same 820 chipset. So I had some kind of expectation as to what battery life around. I was kind of shocked how bad the battery was on the 10. Phone was dropping like maybe 20% overnight. In the daytime on stock before I rooted I was getting maybe 1.5 - 2 SOT hours depending on use(i'm not a heavy gamer). I had never experienced such bad battery life before on an HTC phone. I unlocked it/rooted it and started playing with mods. The most success I had was with the Helix engine. I also had some Magisk modules installed to help deep sleep. Probably improved to getting 3 - 3.5 hours SOT. There is a thread dedicated to getting better battery life on Oreo in the guides section and I'd follow that thread and try various things. Also I had done the HTC calibration a few times, and the HTC battery test just to get a sense of the battery's health. In their test, I scored an 85, so I'd say the battery was OK. Not in the area of being a replacement.
But in the end, I was curious to go back to Nougat and then maybe on to Marshmallow to see how battery life would be. Simply going down to Nougat, I was satisfied. Not quite as good as my LG V20, but close enough. Don't feel the need to go down to marshmallow for it.
Maybe in the future I'll go back to Oreo on the 10, but for the most part, Nougat is fine.
From what I've read as well, HTC sort of 'unleashed' the power of the 820 chipset in Nougat, therefore when people went from Marshmallow to Nougat they reported worst battery life but improved performance especially in gaming.

There is a thread dedicated to getting better battery life on Oreo in the guides section and I'd follow that thread and try various things. Also I had done the HTC calibration a few times, and the HTC battery test just to get a sense of the battery's health. In their test, I scored an 85, so I'd say the battery was OK. Not in the area of being a replacement.
But in the end, I was curious to go back to Nougat and then maybe on to Marshmallow to see how battery life would be. Simply going down to Nougat, I was satisfied. Not quite as good as my LG V20, but close enough. Don't feel the need to go down to marshmallow for it.
Maybe in the future I'll go back to Oreo on the 10, but for the most part, Nougat is fine.
From what I've read as well, HTC sort of 'unleashed' the power of the 820 chipset in Nougat, therefore when people went from Marshmallow to Nougat they reported worst battery life but improved performance especially in gaming.

Im aware on the unleashed power htc did on N, but it just don't justify the amount of energy drained. It does not make sense to remove social or other apps from background just because you need to retain battery. Still have a one M7 and the battery still is way better than this htc, with all the apps and settings i need on both, almost a clone of my m7. Im no gamer at all, and don't use whatsup, viber, FB, g+ etc.
You are saying that just by returning from Oero to Nougat, your htc 10 battery got less discharge, like it got fixed? without any mod's?
Thanks for your time to answer me!

Yeah, for me moving back to Nougat fixed my drain problems. Keep in mind, I didn't own the phone before Oreo, so I can't say what it was like pre oreo. But I finally felt comfortable with the performance/battery life I was getting on Nougat. I can't say this will work for you, but others have reported the same. Moving back to Nougat improved battery life.
Before you do it, I'd advise to rule out a hardware problem though to save the aggrivation of downgrading. Do the HTC battery test. If you fall below 70% in the test after an hour, I'd say it might be more hardware related than software.

Good morning.
Wile i was chating with you (yesterday), finally used the htc battery test and to my surprise it went from 99% to 88% in that hour test (99 because it was off and spent that ~1% booting). So, hopefully, will experience the same as the most of you who made the downgrade.
Perhaps its some part on the process of downgrading that fixes something, maybe the format of the [persist] partition one have to wipe to recover access to the baseband (thus the imei) repairs something, a kind of file system error that makes the android system use a lot of power(?).
As i told before, if do mobile repair and to this day, after several hundred of phone fix (hard and software, various brands as lg, samsung, htc,, iDeveices and china phones, never seen this type of problem unless it was hardware problems like pmic (power management IC) due to use of bad chargers / bad cables, water damage, drop damage, etc. Got this 10 and as soon i got here (xda) immediately noticed the amount of people that had the very same problem. And we are (here on xda) just a few to the many thousands of 10 owners around the globe that don't use xda or any other forums to talk about this problem.
Going to do this downgrade today. Im eager to see the result and use my 10 finally (another agnostic hope :angel!!
Thanks!

Most efficient kernel to preserve battery life for T800

I've had my T800 since pretty much launch day. It was my go to tab until recently when I got fed up with charging it every few hours and bought a Huawei Mediapad 5 10.8. I have passed the T800 on to my wife for reading, casual gaming etc, and I will still use it for monitoring my DJI Phantom 3 Pro flights. But the battery life is still a real bugbear. I have been considering replacing the battery, but a friend suggested using a different kernel to see if it helps improve the battery life.
So I would appreciate if some of you could give me your experiences with different kernels, and how they have affected your battery life.

This is not how things work.
The high battery drain is usually caused by two major reasons. First - the bad battery cell state, caused by extensive wear. This is fixed only by replacement of the battery. Second - the software locks preventing your tab from going into deep sleep state (aka "Doze"). These locks can be inside kernel but as a kernel developer and maintainer of Team Exynos5420 I closely keep track of patches applied to the kernel source and I have zero issues with sleep.
Much more probable, however, is a bad Android application you installed causing a wakelock. Say, Facebook Messenger and WhatsApp are known battery hogs. Identifying them is quite easy using Settings - Battery pane giving younthe app list consuming the most.
If you want an advice regarding the choice of kernel, I'd recommend using LineageOS official ROM for T800. Its kernel is the most stable and tested on many devices to have zero issues with sleep. And don't be afraid of replacing battery - after 3 or 4 years of daily use it surely becomes dead. New battery costs $35 to $50, and I am going to get one for my T805 anyway.

Thanks for the advice. Its really hard to tell with the T800 whether the battery is on the way out, as battery life has never been great anyway. But yeah, I'm gonna stick a fresh battery in there and change the stock rom. Its a small price to pay for reviving such a good tab.
