Stock vs Custom Rom = Which is going to have better battery life?

Just a curious, semi-NooB questions... I've been rooting phones and running custom ROMs for only about 6 months, but I just now started wondering what gives you better battery life.... Stock ROM or a Custom ROM?

The ROM doesn't really affect battery life unless it has bloat that runs in the background. With a custom kernel you can underclock/change cpu governors to save, but really battery depends on whether or not you let things run in background and how long you have the screen on.

With my s3 I found aosp based roms with better battery life then touchwiz. With the s4 i find touchwiz with better life.
If you were asking between stock touchwiz and custom touchwiz there are a couple of factors. A lite touchwiz custom Rom with a custom kernel should have better life then stock non root Rom/kernel because of bloatware removed and slight tweaks. Custom roms with ported apps and over theming can lead to more battery usage.
All battery stats are user and location related so best to run some tests on your own. A test I use is battery usage from a full charge overnight with data/Wi-Fi/sync/Bluetooth.... disabled. I find it a good constant base as long as there are no tower troubles.
One of the best things about android in my opinion is trying different roms and finding the one that suits me the best.

the best part about these types of questions is that you get to do the research yourself. try a few roms out for a week at a time. you'll find your answer.

We cannot answer this question for you it depends on how you setup any rom, how you use it, and all the other factors people above mentioned.
I for one cannot wait to get this bootloader cracked open and try and get 7 hours screen on time with this baby custom roms of course will help me do this

Unfortunately, I'm on MF3 and can't flash any ROMs..... Now I'm sitting here with a rooted stock S4 and a rooted HTC One with a custom ROM. I can't keep both and have to choose which one to get rid of within the next week.
Decisions, decisions, decisions......

Hi in my opinion better battery life then touchwiz and this is best and also i know about that dependability.

Well I can tell you without a doubt: GET RID OF THAT HTCrap!!!!
I have had 5 or 6 HTC phones in the past 4 years, all Android, all rooted and I pushed those suckers hard, but i had to make so many insurance claims on my last 2 phones through T-Mobile that T-Mo cancelled my insurance policy.. it was not that i abused them they just all had issues
Beyond that I can prettty much say with all certainty that once our MF3 devices get that bootloader cracked open, this thing will beat out any phone on the market and certainly that HTC phone you've got!

It all depends on usage. That is all.
Tips:
1. get Better Battery Stats, and look at what is using battery. If you don't need or use an app that is using battery, freeze it or uninstall it.
2. turn off vibrations, auto-brightness, smart sensor, wifi, etc.
If all you do is use the phone to talk for 30-45 minutes a day, look up stuff on the internet occasionally, and for appointments/alarms, then 24 hours of battery life is easily achievable. If you are an avid phone gamer, you're out of luck.

I've been bouncing between the two for months now. Generally TW based ROMs give better battery life from how use my phone. I prefer AOSP ROMs but i usually find myself back with TW

Do custom ROMs depend on only the model number or on the firmware number as well ?

I got 97% deep sleep last night over a ten hour period with SlimKat 4.4.2 AOSP ROM and stock kernel. Best I've ever seen.
That was with Greenify doing its job though.

ROM with best battery life?

Coming from an LG G2 (long story), battery life is what I miss the most. The nexus 4 has about half the screen on time than my g2 did.
I'm already unlocked and rooted but still stock ROM. Are there any Roms that significantly improve battery life?

I found smart 3G on Cataclysm to be pretty good at saving battery.

ROMs and kernels have little to do with battery. Your usage, signal for mobile data and WiFi, screen brightness, your configuration for location services, gps and the like and your apps determine your battery life.

I'd try Paranoid. I used it for a while after using stock and I found that the battery improved.

roms have absolutely zilch when it comes to battery life. only thing rims can do with battery is reduce it. generally, the more added mods/features a rom has, the worse the battery life. but not always. battery life is determined by hiw you personally use your phone, how you set it uo, what apps you use, and the quality of your phone/data connection. everything else, including kernels, have a very minimum effect on battery.

Well
When I was with Carbon, the play store thing killed my battery to 3hrs on screen time
Switched over to Purity Rom with Hells kernel and I have 5-6 on screen time
WiFi on all the time, no data or GPS or Bluetooth.
Mostly Reddit and a game or two, and a movie

Okay, but why is the battery life better with an another kernel?
I use the HeelsCreed kernel and Mahdi rom. My battery life is better with the HeelsCreed kernel as with the Kernel of the Mahdi rom.
P.S.: I know my english is bad, sorry for that

set up your CPU and everything else just how the kernel sets it up for you, and you'll get the same battery life. be more active, set things up manually.

can you tell the story please , anyway ROM has weee little to do with battery life , its mostly on how you use it and the kernel you are using as well as sync loops and dodgy leaky apps , my personal setup is rom = paranoid android and kernel = hellsdoctor , using synapse app i switched the maximum clock speed to 1.2 Ghz , and changed the maximum core online to two, gpu is overclocked by default , rest is, location settings are turned off only turned on when required , brightness is set to 50 % , no dodgy apps on the phone , i can squeeze about 5 and half hours sometimes 6 its good enough for this battery size though and hope it works out for you :good:

[Q] ANDROID IS JUNK! (Battery "life")

Every time I track down what is sucking my battery Google come up with a new way for Android to suck even more. I have sorted out various apps, location services, underclocking, etc. Now I find that when there is an update waiting the Play Store punishes me by sucking the juice out of the battery - even though I have it set to automatic updates and to give me notifications if there are updates waiting. No notifications and sometimes the waiting update doesn't even show up in My Apps, unless you switch to the Store Home and then back to My Apps. It might make a little bit of sense if these app updates were waiting for you to approve a change to the permissions but that isn't the case.
I have this problem on my Nexus 4 running rooted stock Android 4.4.4 AND on my waterproof Moto Defy+ running uprooted stock 2.3, so I'm guessing it is the Play Store which is junk. Does anybody know a solution to this? Please? I have tried searching for solutions but there are SO many battery/Android OS problems that I haven't been able to find the answer for this particular one.
I'm almost tempted to go for an iPhone - except that they are junk too. Maybe my next phone should be a Nokia 3310.
(BTW "junk" wasn't the word I originally used)

You're never going to get zero percent battery use, maybe your expectations are out of line?
How much screen on time do you out of a full charge? And what's your %/hour drop when the phone is sitting untouched?

google doesnt come up with a new way for android to suck more battery , YOU DO , note the keyword is YOU , now figure it out .

I was getting under 2% per hour drain then, without me making any changes, when updates came along and Android didn't tell me and Android decided to suck my battery it goes to something like 10% per hour

battery life is all dependent on YOUR personal usage, your personal setup, your personal decision to install whatever apps, and very much your phone/data signal. if your data/phone signal is only so so, then youyr battery life will only be so so. if you have things draining your battery besides for your signal and use, its up to you to figure out why. thye battery klife of my nexus 4 and nexus 5, actually, all androids that ive ever owned, has been wonderful. i get the same google apps updates as you, no less. so you have to figure it out.

OK, so as I said previously, with no changes made by Me I am finding that when app updates come along my Nexus doesn't alert me to the need to update but if I don't spot that an update is needed "Android OS" usage climbs and drains my battery until I look for an app update and update it. This is without loading any new apps and with the good signal I always have and all the things I normally have turned off (wifi, BT, location history, Google Now, etc) and slightly underclocked (1.2 GHz).
I'm sorry if criticising Android has offended people but I'm asking if anyone can help me solve yet another battery drain. Assuming that I'm doing something wrong isn't helping unless you can point me at what I'm doing wrong. All I am seeing is that I've sorted out all the known battery drains in my personal set up and yet updates, over which I have no apparent control, are causing another drain. I would like to hear from anyone who might be able to help and I apologise to anyone who is offended that I see an imperfection in the phone we have all chosen.
Thanks in anticipation.

You need to find out what's causing the battery drain. Get gsam or betterbatterystats. Without one of those you're just guessing.

App updates come along. Play Store is set to give notifications and to auto-update. Some app updates don't give notifications and "Android OS" causes a load of wakelocks until I spot that the update needs doing and do it manually. Same thing happens on my wife's stock Nexus 4. We are both in the Uk on Three network and have good signal.
I have BBS but I need to see what it says when I get this app update problem. I will post my findings when I get the info. If nobody here recognises this problem maybe I need to look at what is similar between our two Nexus 4s. I know we both have WhatsApp and, of course, all the Google apps, both on 4.4.4 but there the similarities end.

Why don't you try a ROM other than stock? I have flashed countless phones and tuned ROMs always offer better battery life. I don't understand why people go through all the effort of rooting then stick with stock ROMs. I know the general consensus is that the stock ROM (on the Nexus anyway) is one of the best, but let me tell you the general consensus is wrong. It is good, but there are much better custom ROMs.
Oh, and stock 2.3 on the Defy??? Come on man, why are you on XDA? This isn't the Carphone Warehouse helpdesk.
Try something barebones - no bloatware/small rom and choose barebones GAPPS. This will make a huge difference in battery life before you even dive in and stark tweaking further.

You're wrong. The rom will make very little difference. I constantly get far over 5 hours sot with stock rom and kernel. It's your signal quality and the apps you use and how you set then up that makes the difference

one more thing, you do not need root or to be rooted to run a custom rom or kernel. the only thing that root is need for is to change system files or to run root apps. but yea, you can get great battery life on stock.

I have been getting great battery life from the stock ROM after a few tweaks apart from this problem with updates. I have had a couple of other ROMs on this phone but went back to stock after the last couple of system updates. When I'm not having this particular battery drain then, if I leave the phone alone, I'm getting about 1%/hr battery drain. Also my wife doesn't want her Nexus "messed about with" and it helps if the two are fairly similar. Xposed is the big difference between the two.
The Defy+ is on 2.3 because I only use it when I'm out hiking and it might rain. The Defy is not easy to upgrade and 2.3 was where Android got good, so I'm OK with it, if that's all right with you.

BTW I have a degree in Electronics & Physics plus 17 years postgraduate experience in software engineering in the defence sector. So it's not that I'm not technical I just choose not to make a hobby out of keeping my phones working.

A stripped down ROM running only the bare minimum can greatly improve battery life! Just have a sift through some custom ROMs and you will find the ones that are tuned to do such a thing.
Also in reply to others here, the advantage of being rooted means you can remove unwanted system apps, underclock etc which if you're concerned about battery life would be quite important I would have thought.

This is what you need to do if you want to persist with the stock ROM. I personally have used betterbatterystats with success. Use this to check wakelocks as these are often the cause of mystery battery drain. There is an old but useful guide to that here: http://forum.xda-developers.com/showthread.php?t=1827676

Flashing Franco's Kernel (which is geared towards extending battery life) and Franco's Nap Time (which puts your phone in deep doze mode as soon as the screen goes off) will give you better battery life, but with a trade-off negativity affecting the performance and functionality of your phone. You have to decide how important extending battery life is to you.

I use Cortex Rom, I see someone else recommended Pure Nexus, which I think is an insanely overrated Rom. I've never used a rom to improve battery life but Pure Nexus gave me crap battery life compared with stock and was buggy to boot. The downside with Naptime is that everything pretty much stops working when the screen is off unless you exempt the app from power saving. That includes music playing apps, email apps, text messaging apps--whatever you want to work you need to exempt from power saving. If you let Nap Time turn off your proximity sensors then the only way to get your phone back in on is by hitting the power button.

Best ROM so far for OnePlus 2 or Solution for battery life

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.

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).

AOSiP it's a rom - Android Open Source Illusion Project
NGK it's a kernel - No Gravity Kernel
SOT - Screen On Time

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)...

I did, really awesome app but I'm not sure that I understand what is saying to me. And I don't think that is battery issue because before this I had a really good battery life. I'm sure that if I do a fresh install of new ROM, battery life will be great but only for few days.
Can you explain this please with simple phrases? How was the performance? Do you use it now?

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.
