Which ROM has the best battery? Is it Stock because it has more battery optimizations or is it a custom ROM as they are more simple?
Please comment your setup along with your ROM and usage.
Thanks for the help
i am using resurrection 5.8.3 and the battery life is great!
at the moment i am 10h SOT with 40% battery remaining
I think stock is a safe bet. Coming from an LG G2, the P2 surpasses my wildest dreams. Could possibly get 20 hours SOT with very light use.
I agree.
I believe Lenovo optimized everything about the official ROM so as to provide huge battery life, from the auto brightness all the way to background process killing and signal search. I doubt any other ROM can achieve the same result without being severely hampered, unless it's some battery driven ROM.
Rooting the device while keeping the default ROM might allow you to tweak things a bit further and squeeze some more juice out of it, although I doubt much more can be done.
Then again, you might want to consider what you use the P2 for, and how much battery life can be expected from that usage... For example, I use mine for gaming all day on mobile data, and it lasts 8 to 10 hours! My previous device lasted 2 hours and a half under the same conditions with any ROM I tried, so I really don't expect better.

I'd like to hear some experiences that everyone is having on how the battery life is on the stock ROM (POST OTA, NOT OVERCLOCKED) vs custom ROMs (Again, NOT overclocked).
I've tried the Virtuous ROM, and as expected the battery life got slurped down like coca-cola! CM6.1 isn't as bad, but still seems to suck the life out of the battery quite a bit faster than stock.
Is everyone seeing similar? What makes the stock ROM so much better on the battery?
My experience was actually quite the opposite. When I switched to CM, my battery life improved by about 20-25%. I have a NAM Desire Z so it was running HTC Sense over Froyo.
Remember that it takes a few days of usage for your battery to 'calibrate' itself to the new ROM. My first two days on CM were really bad, but since then, battery life has improved greatly. Yesterday, after moderate use and 15 hours, I still had 45% of my battery left. With my stock ROM, I would be lucky to get 15 hours of use out of the phone period.
As far as overclocking goes, I haven't seen much of a difference in battery life. Reason is, even though you are overclocked when the screen is on, you can adjust settings to under-clock at other times, saving battery power.
I would recommend trying a Custom ROM for 4-5 days, that will give you a better idea about its battery life. Also, there are lots of settings you can tweak that affect battery life greatly. Widgets, background data, signal strength... SOO many variables in personal usage that battery life is going to fluctuate user to user regardless.
Hi,
This question is for anyone using the latest CleanRom on their Note II. Just wondering if your average battery drain is around 4-5%/h. I use BetteryBatteryStats. I also check the Battery section under Settings. The most battery life I have been able to get is 12 - 15 h with 1-2h screen time. At this point, the battery is at less than 10%. Is this normal ? I thought I remembered getting better life from older versions of CleanRom. I know these numbers are never achievable on any AOSP rom that I have tried. Just wanted to see what everyone's experience is with battery life. Just post any thoughts!
Thanks for your feedback! I appreciate your time!

Just like anyone else, it all depends on what kernel you're on and what apps you have wakelocking. I've been using Clean 5.0 as my daily for months and the battery life lasts me throughout the day until I need to sleep at which point I plug in... but sometimes, I'm running into fast battery drain due to some apps going nuts on me or when Bluetooth is trying to link from a long distance (where the phone would heat up and drain like mad... btw this only happened to me twice in many months). After a reboot, it usually clears up and after a recharge, I'm back to 14 hours with 20% left at night. I'm not one to be anal about my battery drain if it lasts me until I sleep (because I have NEVER had a smartphone that would last me that long without plugging in... in fact, barely half the day would be when my device would need to be fed).
I'm using Perseus' latest with a few screen tweaks, no CPU or power tweaks, using Facebook constantly, Pulse, SMS/MMS, camera throughout the day, Next 3D launcher with all the fun animations running, YouTube, Pandora when driving (so my Bluetooth is on constantly)... let's just say I'm a heavy user. When my kids get a hold of my device, they run a bunch of games and drain around 10% by the time I get it back.
I am happy with the battery life on my Clean Rom 5.0/Perseus Note II. I won't fuss about it as long as it lasts longer than half the day because that is what I was used before upgrading.
What would be the best ROM for battery life? I'm using CyanogenMod atm and the battery life is decent. If I flash Android Rev. would I sacrifice battery life and if so by how much?

Battery usage is completely subjective so what will be awesome for one may be absolute crap to another. Only way you'll know is to try it yourself

As mentioned, battery life is completely up to your usage. Some steps to try though which can be used across any rom is to give Rom Cleaner a shot and to use Greenify. This will rid any rom of bloat that could be sucking up battery and better allow the device to enter deep sleep where the real battery savings are had.
A well optimized kernel would give you some savings as well. I can personally say that on ARHD 5.5 with Elemental kernel .15 I'm seeing about 70% battery left at the end of a normal day. For me though that may only be one 20 minute call and an hour of screen on time. Even when flashing and messing with tons of settings for hours, the phone has never reached a critical battery level for me. I
It's more about the way you optimize (or debloat) your phone , than the ROM you are running. Use battery monitors like GSam or Battery Drain Analyzer and freeze apps that are causing you huge drain. Greenify is also good. Ideally on the M8 you can expect around 6 hours of screen time if you're optimized correctly.

This. I am able to get about 6 hours on stock, ARHD and Insertcoin. With power saver on, that ends up around 7-8 hours of screen time. Coming from a Nexus 5 that got 4 hours typically, I'm pretty satisfied. I'm inclined to believe ARHD will get "slightly" better battery life than CM since it is based off the stock ROM on the M8.
Generally the OEM skinned roms have better battery life and benchmark scores opposed to aosp. Happens all the time on Sammy phones and HTC apparently too. Posts above mine cover most you'll need to know. Its all about optimization and frankly that part is extremely fun and especially rewarding IMO. Gives me an idea for something like a community made thread on different battery tweaks/voltages :good:

Thanks for all the feedback guys
I'm currently using Android Rev. 6.1 odexed (using ART atm) with ElementalX 0.10. I don't know if this is a placebo effect or not, but after flashing ElementalX(with default settings) my battery life seems worse :/
Hello, I've been thinking of switching to an AOSP-based ROM. However, I want to know if the battery life will be better or worse, and I need opinion from people who have tried an AOSP-based ROM.
I've heard that they give better battery life on other devices.
I'm not asking for "which ROM is the best", but I am asking what your experience is like with battery life, so I have full confidence that this kind of thread should be allowed. Thanks.
I personally haven't noticed a difference between the two. I'm currently running Candy5 and set the IO Scheduler to 'row'. It lasts me throughout the day. But to be fair, I don't use my phone very heavily. With heavy gaming, I'll go about 2-3 hours from a full charge to about 25% charge. I don't know if this is something that is universal or not, but the phone gets REALLY hot after about 5 min. of gaming.
Ok, so I got my new N5X 1,5 week ago. Before that I had the Z3 compact. After reading around on xda and reddit I decided to go with the purenexus + elementalx combination. Have been tweaking the kernel with EXKM with both bluejay, ghost pepper etc.
But the problems arise after >20hrs uptime. The lag and stutter gets really bad. Also the battery life starts to get eaten up (2-3hrs SOT with ghost pepper settings). I use messenger, Facebook, snapchat, chrome etc. I know these are memory demanding apps, buy I never experienced stuttering and such battery drain on my previous phone.
BTW, my idle drain is really good. Less than 3% during the night. I use amplify for wakelocks.
Don't know if I should try to change kernel or rom? Or just factory reset it to stock? Even though I love root..
Some suggestions would be greatly appreciated. Thanks
Try purenexus with the kernel it comes with. It performs great with good battery life
I personnaly loved root and everything, did try purenexus with elemental x and a few tweak profile too
Result : no better performance, no better battery life, random bugs and hot phone with lags from time to time at the end of the day
I'm back to stock not rooted and I got to say I don't miss anything and the phone flies.
This is my personal experience.
I also recommend purenexus with its built-in kernel and leave kernel related values as they are. You should decript your data partition to get most out your N5X. Encryption is putting a considerable strain on CPU and battery and does not offer much in return (debatable). With Pure Nexus I get outstanding performance, amazing battery life and rock solid stability. Using it since tuesday and not considering any other rom for now. Just decrypt your data partition.

What's the difference in battery life for you? I've never decrypted it, but I'm thinking about it.

With my usage i get about half an hour of SOT more. Im averaging around 6+ hours with 10% left. This is mainly on WI-FI.
Is there a simple way of finding out what prevents Doze from kicking in on an unrooted device, or is it trial and error without root?
