So I basically have Stock 2.2 with a lot of the unnecessary apps removed. The other day I installed King's 4th Kernel hoping for better battery performance but in the end it's a little worse. I'm not blaming the kernel for my performance issues. But I'm looking for feedback to get better battery life.
Right now I am not using Set CPU. I just flashed the ROM, wiped the dalvik cache, and decided not to wipe the battery stats. I've been using the #4 kernel for two days now.
I work my phone pretty hard every day and have a good idea of when it's gonna die. I don't bother bump charging but rather replace the battery with a spare I have on hand.
Any recommendations to fix my problem?
Try a different kernel?
Get Set CPU? I'm not interested in overclocking but I realize other features are available.
Wipe the battery stats?
One thing I can say for certain is that I've been using this kernel with my current setup for 2 days now and battery performance is worse. Something definitely needs to be tweaked in my engine because I shouldn't have to use 3 batteries in one day.
Again, I want to reiterate that I know there are a lot of factors that affect battery life. I'm basing my opinion off of my past battery life throughout the day. It's probably not the kernel but how I have things setup. I'm just looking for some direction to extend the life a bit.
The biggest thing to do will be setcpu. Underclocking during screen off and using conservative governor will drastically improve battery life.
I haven't ever had good luck with the King kernels on my phone. Adrynaline's Custom kernel has worked awesome for me though. Took it off the charger at 11am yesterday, used it regularily and didn't charge until today at 3pm and still had 32% battery left. I use SetCPU for underclocking the phone when the screen is off and that seems to be the best way to save battery. I also don't have anything syncing throughout the day besides gmail accounts.
Ok, well I guess I will start with Set CPU. Sounds like it's worth the cash. Maybe I'll try a different kernel at the same time.
Thanks.
Setcpu is available for free to xda forum members. Do a bit of searching around and you'll find the link to the .apk

Setting CPU Max at 555 when screen is off took me from 9-14hours to 25-30hours.
Clearing battle stat seems important
I like interactive mode when it seems to be working right. I don't really know what Interactive mode is except that setcpu will show the CPU jumping to differant frequency instead of ramping up like with conservative.

I knew this and had forgotten. Fortunately, right before I dropped the cash the light bulb came on. I appreciate the heads up anyway.
Has anyone had luck with King's Kernels?
srt4mn, do you have a link to the kernel you are using?
The kernel comes with the Virtuous ROM and can be downloaded as a separate entity from ROM Manager in his area.

Ok, cool. I'll give it a shot. Is it tweaked to work just with the ROM or is it safe to install in Stock 2.2 as well?
Clambert11- Sounds as if you wrote your post for me. I haven't tried a custom rom or kernel yet but KK was the what I was considering. I do have setcpu running for a couple weeks now with underclocking for screen off, battery under 50%, and battery under 30%. Have noticed a modest improvement, mostly while phone is asleep at night. Not really much difference with day use. I carry a spare battery and charge at every opportunity.
I'll be watching this thread to see how the new kernel works for you. Sounds like it can be installed over the stock 2.2, yes? Does it require a full wipe?

I just installed Virtuous Custom Kernel - Version 2 without any issues. All I did was wipe the dalvik cache. I'm still not a firm believer that wiping the battery stats does anything. Now to setup SetCPU... I will report back in a couple days.
I tried bump charging with wiping battery stats a couple days ago. Didn't see any difference.
I be watching for your post. I'm happy with my rooted stock. This phone has more tricks than a $2000 hooker. The battery life is the big problem for me.
In regards to wiping battery stats, here's what I do and what seems to work good for me.
This is best to do when you have times when you wont need your phone to much.
1. Full charge phone while phone is on
2. Leave USB/power cord plugged in and turn power on phone off
3. Wait for the LED to change from orange to green while phone is off, this means you have a full charge.
4. Power on phone to get to recovery
5. Go to advanced > clear battery stats
6. Reboot phone
7. Pull out charge cable once your phone fully boots
8. Fully kill phone battery without plugging it in to USB or power the phone until it dies completely
9. Turn phone back on with charge plugged in after battery fully dies and phone shuts itself off, charge till 100%
I also keep my screen brightness down really low, this seems to help maintain good battery life too.
Those are good detailed directions. I had been wondering about when to plug and unplug. I also never fully discharged the battery. Li bats don't have memory issues so why fully discharge? Is the claim that this effects or resets something in the OS? If so where does this info come from? I wonder if someone pulled it out of his butt and it has become doctrine. Did you really see a difference? Did you try something else like lower screen brightness or setcpu at the same time?
i've been running bfs #4 on stock rooted 2.2 for about a week now. loaded the kernel through clockwork. it's working good for the most part and i've been keeping it mostly at stock speeds. however, i have noticed an occasional lag here and there (that i didn't noticed with the stock kernel) but no reboots or lock ups. i'm going to disable setcpu to see if that has any impact.

You pose a good question. I myself dont know the source of the battery stat information, and coming from apple products I've been conditioned to not asking questions, but I can claim from experience that wiping the battery stats help the OS more accurately report the battery percentage.
Since I recently reflashed a new rom and kernal, my discharge rates were rather wonky. The first 15% went pretty fast (as they usually do) since I didn't bump charge. Then it remained normal till 50% when it spiked till 20%, then remained normal till 15% where it took forever to diminish.
Wiping the battery stats will help this number be more consistent since (to me) it helps the OS learn about the battery in conjunction to the kernal being used. I'm assuming that this feature exists because we can swap batteries. Ever curious why apple locks their batteries in their devices? If I had to guess it would be to avoid this whole debacle. They only use one type of battery for each device and as such can report battery percentage more accurately. Plus its easier for them to design.
I've gotten sick of bump charging, so I reset my battery stats after charging to full and not bump charging. This should give me a more accurate drop in battery for the first 15%.
This is all information I've gathered through experience. I do not program these devices, so take it for what its worth. If any Li-ion engineers are around here, help!

Just an update. I've been running Virtuous for a few days now. I thought I installed Custom Kernel v2 but the System Settings say v1. I'll have to look into that. Kinda odd.
Anyway, I also am using SetCPU, which I think is responsible for most of the savings I have received. I've got the default scaling set to Conservative. Additionally, I have a Screen Off profile of 245 max / 245 min in Powersave and a Battery < 10% profile of 806 max / 245 min in Conservative.
I'm still playing the kernel / SetCPU game for the optimum settings but I've bought another 1.5 to 2 hours of life without feeling any real performance woes. I'm hard on the phone and use it a lot. That's what we have them for, right?
I had issues with King's Kernel #4. My phone, at times, would get real sluggish without even using SetCPU. I may try some of his older kernels or his next kernel (when it's released) to see how it behaves.
Just wanted to touch base. Thanks for the previous input and guidance.
Thanks for the update! I think my greatest savings so far has been from a screen off profile at about 460 max. I also have a 50% and a 30% profile.
Hi everyone! I am on the stock kitkat GNG8 and my battery is not good at all. I get arround 2 hours on screen time from a full charge in a day or less. I tried updating to Lollipop, but reverted because some of the bugs, and the battery was not that great either. I have 2 original samsung batteries, and both get drained pretty fast. Any rom/kernel confinguration that can get me at least 3 hours of battery life please? Thank you!
I'm using the Imperium ROM: http://forum.xda-developers.com/galaxy-s4/i9505-develop/rom-imperium-ll-v1-0-t3046889/page92
My best Kernel to avoid batery drains, was the Googy Kernel, and the settings as "Conservative".
But don't expect so much, I also get 100% charge, and in just a 5 minutes, I get about 90% (with a brand new batery and even another one 7200mAh with 8 months of use).
This sucks, I know, but it's what it is.
Avoid to get all the time the screen on, and sometimes power off the wireless/nfc/BT, or whatsoever connection that you wouldn't use it.

I'd recommend Danvdh's GPE rom. It has a nice battery life. I can't tell you how much screen time you will get 100-0% because I generally don't let it go under 50%.
But I can get around 2 hours, from 100% to 50% (while gaming) This is with wifi and bluetooth off. Screen brightness at the minimum and no vibrations.
Anyway. It's worth a try. And many people praise the rom. It's also the most bug and hassle free lollipop rom I've tried.
Or you can try any AOSP rom and Ktoonsez kernel. It's a really awesome kernel. Look in the Ktweaker shop and download some kernel profiles and switch between those. There are 3 categories: Conservative, Balanced, Performance. I guess they are self explanatory.
I used Sleeping-Dragon 1.2 Single Core (Basically turns your phone into a single core phone. It is still surprisingly smooth though) as my battery profile. There are several profiles for each category.

Hi xda family
What has everyone's battery life been so far on root?
Preroot I was getting over a day with 6sot and 16 percent
Android drain.
After rooting with the eng kernel it has dipped a lot with high android system drain. Have not used amplify and greenify yet. Just been used my tweaks I did on pd7 kernel.
Thoughts?
Amplify will probably help out a lot. I've seen others reporting the battery is worse after rooting as well. Hopefully someone nails it down and posts a fix. If not, I'll see what I can do once (if) I decide to root.
Yeah I can literally watch my battery % drop after root. I noticed 46% of use is the android system. I'm also getting lots of random reboots.
You guys rooted with an EngBoot that was not intended for daily use, this is one of the side effects.
Yeah the ENG-BOOT is a terrible way to achieve root. I really hope that this tiny victory doesn't cause people to stop looking for real root. The ENG-BOOT is not meant for daily use is going to cause lots of issues, it's designed just to push fixes to the system for an authorized repair shop.
The focus should have always been on the bootloader.

Wow 46 is high. To be honest for eng kernel it's been stable. No lag and reboots for me. I am debloating and doing a few tweaks and making it settle in some more. If I can get to 4 sot I will take that.
Also I have heard if you your governor set to on demand it will cause reboots. Using interactive and been solid.

TEK knows what he's doing, so I'm sure this will at least help with battery. This, plus Amplify and BBS+ should at least help get battery close to where it was before root.

Thanks I am following. I have gotten android system drain down to 13 percent with amplify.
Things are looking very promising but will see how the next 48 hours go.

+1 it runs a lot cooler than the normal stock rooted. And way smoother without have to tweak anything with kernel. It's basically plug and play.

dam we got root now? I didnt even know
With all the different tweaks now available through root, the battery life is quite excellent. The only concerning thing is how hot this phone can get at times (after a reboot, gaming, downloading an app) that I may be doing great harm to my batteries life in the long run.
okay so,
the engineering kernel's default governor is performance and that's the only thing that's causing the heat issues and thus, the throttling of the CPU cores to lower frequencies resulting in lag/stuttery performance. that's all you're experiencing. thinking that apps are using more/less battery than usual is silly.
after wiping data and cache and going through the horribly slow setup process, I used kernel adiutor to change the governor back to interactive (NOT ondemand) and let the phone finish settling/syncing. after 2 days, it's back to its silky smooth performance and all-day battery. I don't see anyone experiencing anything other than symptoms of the performance governor.
btw, it took the same amount of time for my phone to stop being laggy when I first bought it. so literally all you need to do is change your governor back to interactive if you want the performance/battery life you had before, and zero heat issues. antutu scores 110k-138k depending on temperature/throttling. just like it did before. battery gets 4:30-5:30hrs SOT just like it did before.
TL;DR

I used kernel aduitor too till I found out my big core were maxed at 1500 also just like the little cores and you can't change those with aduitor.
Once I installed kernel toolkit, I confirmed it.
So I bumped up the big cores max and got much more speed back. No heat here
Food for thought.

Hello guys. I know that this is a very common question not just in OnePlus 2 forum. I read some posts of this, tried, but no success. So far I've tried couple of ROMs but battery life is so disappointing. Best shot was RR ROM 8.1 official with BB kernel installed. After system and kernel installed, I've done a wipe of data. I wanted to make sure there is nothing except system on my phone. After that, all necessary apps I use. That was operating very good in few days. But recently, out of nowhere, battery life is awful! Over the night, with no use and battery saver turned on, I loose more than 20%! I know that I haven't downloaded any additional apps after first days of installation, I haven't changed any settings since first day... I added fingerprint lock 2 days ago and yesterday I turned it off. So What is going on??? Phone is not overheating, seems like there is nothing in the background running to drain battery.
If you know what could cause the problem, it would be very helpful. But I'm also opened for installing a new ROM, kernel...
Who is here with good battery life? Gimme some advice! Btw, I don't care if it's N or O, or anything as long as it's operating well, reliable and no bugs. Thanks!
That's probably a battery issue, install AccuBattery then see how much health your battery have(requires few charges).

I reached (haters gonnah hate) best battery life on lineage 13 with boeffla kernel (zanezam's uber builds, use some battery safe profile from profile thread or make your own), amplify, greenify (optimized accordingly to the corresponding thread, with xposed) and NO GAPPS. Get about 3 days with SOT of 2-4h or a sot of 6-9h on 1 day (on an old oneplus2, no gaming). You can also use dualbootpatcher and a second, battery optimized (but lagging) ROM so you can switch when you can't charge your phone for a longer period of time.

Forget everything with dualboot patcher, you would probably mess up your phone.
For everything else, use xda search. Seriously, you only have to type the apps i suggested 1:1 into the adress bar and you will find it! If you are too lazy for this, unroot and go back to stock.... seriously...
Edit:
Yes, i'm using this now (lineageos13) with a self compiled boeffla kernel (uber 8, camera focus fixed on 6.0.1 roms), greenify, amplify (own build), xposed (needed for amplify, greenify works better with it) and no GAPPS (= google apps--> no playstore, youtube, etc--> draining battery as hell, idk what they are always doing in the background...)
My boeffla profile: 3 cores 1250mhz max, big cores disabled, battery extreme governor, system and my apps (whatsapp, telegram, 9gag, browser) work fluently (they start up a very little bit slower than before).
Battery profile is same but with 2 cores 675mhz, still only few microlaggs (you have to disable all animations in developer settings), internet browser is slow (use a lightweight browser, such as firefox focus) apps open up slower but aside from that the phone is usable. If you're interested in the kernel and my profiles, please tell me (you still have A LOT of work to do by yourself, such as setting up amplify and greenify, disabling (system) apps you don't need, adjusting everything for your needs, deny unnecessary permissions on app ops xposed, etc).

Results can vary. As someone who flashes way too many ROMs - its an addiction - I currently use crDroid Oreo as my daily. I also flashed the blue bolt kernel. This seems to give me good battery. I do have a rooted version of the stock ROM I flashed in twrp backup. Just in case. With crDroid also backed up I can move quickly from one to the other in about ten min without losing all my settings. It is a good idea to occasionally do a fresh backup of one or both since apps added or deleted or updated and any changes you've made since last backup will not be kept otherwise.

Do you know dualboot patcher (google it )? Very nice opportunity to have multiple roms installed on the device (which even share the data for specific apps--> u have all your wa chats from one rom on the other, directly after reboot). Wouldn't recommend for people who can not restore a backup over adb (unexpected things can happen, but way better than always saving and restoring a backup)...

If you don't mind for a worse looking screen quality, you can use terminal emulator (with root), do a backup in TWRP(ALL partitions!) then type (hit Enter after each line):
"su" (grant root if asked)
"wm size 720x1280" (for 720p, it looks about the same as 1080p, u can also use 480x854)
"wm density 300" (200 for 480x854)
Then u can lower your cpu frequencies until it lags. (and disable system animations, my phone works fine at 480p with 2 cores at 768mhz max freq) will post sot/running time (without charging) when i have the time to test.

Just install akt apk and select sd820.

Has anyone used this [AKT] Advanced Kernel Tweaks with their LG V20?
If so, how good is it?

Just an FYI the akt tweaks only work on nougat. Development ended quite awhile ago. My understanding the devs moved onto oreo and developed some tweaks search xda for something called helix engine I believe

I tried AKT on Classic rom with BTTF kernel on Ls997 and had no luck. Not sure if it was rom or kernel or what. Seemed to cut battery time in half instead of doubling. AKT would be sweet if I could get it to work right. Kernel already has no touchboost imbedded I guess btw.
Here's my results on alpha nougat, mk2000 bttf kernel with akt tweaks

What profile if I may ask?...I was trying Xana extreme and few others. Did it take long for results to start showing?

Go figure...the first selection lol. I will test over a few days and see what comes about and then Ill post results.
Just a quick update so far... I am currently in midst of testing the Xana Extreme again because on my cell I was experiencing no lag or if any very slim and wanted to real test as I got it working properly via app version. The Zanah didnt seem to cause any issues as it also did increase a few hours of battery life. So far however with the Xana extreme I am currently on 26 hours since full charge and no plug since at 56% battery left. I know it is about SOT, but total life is just as important. No restarts as that kills the test. Im happy and impressed so far. Will post more after battery nears death
Here of some pics of current test so far...
You could try this as well https://forum.xda-developers.com/android/apps-games/app-kernel-profile-manager-t3799348

Which of the files did you use? (OP3? OP3T? KPM125? KPM.prj?)?
What settings?
What's been your results?
Thank you for sharing this.
Here is the final result...even though not showing much as for screen as I did not use too much, but overall battery is epyk . Still showed main results luckily after a reboot because it died before I could get a "before death screenshot".
Thanks for these... Is everyone using mk2000 kernel, or is there a better battery life friendly one (for US996)?

I'm currently on aokp rom so haven't tried this. I would suppose it should work with op3
Here is a shot of my initial rundown of a new 4100 mAh Li polymer battery that's the same size as the stock one (mentioned in the Accessories section and the V20 Subreddit), getting past 10 hours of screen-on time. You can ignore the averages section of the screenshot as it's the first run.
Setup: LS997, ClassicROM ZV7 | mk2000 BTTF kernel | AKT 1.6, OnePlus3/SD820, Project Zhana Battery profile
I also turn on aggressive doze when idling overnight using Naptime, dim the display down after sunset using CF.lumen, and auto-brightness is on.
So I decided to switch up atm because I wanted my GPU to not be bogged down at all. I checked the Xana battery in the balanced area and was fairly impressed. For absolute no bog down and fully clocked GPU/CPU for full performance and good battery I recommend this. Sure the results seem less, but my battery has also had hundreds of restarts and charges since I got it and who knows how many before hand. A brand new would show better. I also have a dynamic wallpaper and am running Dolby and Viper as well. Same kernel. Same rom. Same phone.
Also the pic shows 15% because phone died before I could get proper screenshot, the 95% is the key and results are still accurate.
This is my final post as to testing for this thread.

Mysticblaze,
I wanted to bring the conversation from "[Discussion] Improving efficiency and battery life of the V20." back to here since we started to get into some talk about this AKT.
There, you said, "I can get around 10hrs sot (depending) using Xana extreme battery. That's the one I'm currently on.
Have a 4200 mAh battery (reg size)"
1st - what ROM and kernel are you using with that?
2nd - is the battery 4200 or 3200 (mine's a 3200)?
3rd - any other settings I need to know about to pull 10 hours SOT?
Thank you so much!

Yes, 4200. It's a Shemnz. Got from eBay. Rom is Classic for ls997. Kernel is latest 7.0 mk2000. Hard to say on other settings. My test tho was an up to.
I left screen always on with a live wallpaper running with a covered proximity sensor for lowest Auto. Got about 10 and a half.
