Request: Tutorial for best battery performance

I've seen some pretty beastly battery times for some of the users here and haven't been able to achieve the same results on my phone. I'm running Synergy 1.3 w/ imoseyon kernel. I've also done the terminal change (su-cpu-option 8-etc.) and haven't seen a great improvement.
To any of you that are experiencing amazing times, can you please offer a good breakdown of what you did to get your results? I'm sure many of us would really appreciate it.
Thanks!

Since the first post, I've changed the nightly Synergy ROM builds and have flashed IMOSEYON's kernel. While I'm good with my battery, I would like to know what some of you did to get the beast battery life that some of you have shown.
Is there multiple methods you all are using or is there one base method I can start with and tweak some stuff from there?

I'd be interested to know as well. Are their diffent widgets that are notorious for sucking the life out of our phones. Services etc. News updates, mail things like Pulse and Flipboard and Weather updates and screen birghtness. Surely there is interest in this.

Stable rom

Hello everyone, I just got my new skyrocket and I really liked him but one thing really disappoint me, the battery
It's die very fast... So I want to install a stable rom that have good battery life.
If u know one pliz let me know !
Thank u :laugh:

Many of the jb roms are stable and have better battery life than stock ics you'll have to try some to see what works best for you. I'm running liquid smooth with h0tcaze kernel.

I agree, you'll need to try out some custom ROMs yourself and see which ones you like better. Remember to give each ROM at least a couple of days of usage so as to it can settle and a full battery cycle before judging its battery life.
Personally, I'm using SkyJB and happy with its battery life. You should be able to get 24 hours on a charge with 2 hours of on-screen time.
Good luck!

I've long been a fan of SeanZ's ROMs, but the latest builds of SkyJB have left me wanting. I've spent the past couple of weeks on car vs. driver's Nibbles ROM and it's a work of art. Couple of kernel choices, high levels of customization, and install only the cruft that you want.
While I still think it's the best choice, moving to a custom ROM isn't your only option, either. You can consider instead just rooting your stock install and then doing a small bit of work to better improve your battery performance:
Make sure you're always using the stock charger, using anything else will often prevent your phone from entering Deep Sleep
Use something like Titanium Backup to freeze all the carrier and Samsung garbage
Turn off automatic brightness, and Wifi/Blutetooth/GPS if you're not using them
Turn off auto refresh on all of your social network apps (this is the dumbest default-on setting I've ever seen; why does anyone need to download newsfeeds when they're not looking at it?)
Keep a close eye on Settings/Battery and use BetterBatteryStats to see what's truly doing the damage
Just remember to make a nandroid backup of your entire phone and make multiple copies of that backup before proceeding with anything.

Good luck!

In also installed Nibble a couple of days ago, two kernel options, can't remember the name of mine, it had a Z in it, and it was version 3.
I had used Sean's on ICS, and was going to go to Sean's JB, but I started reading threads and liked what I read about this ROM.
It is the most stable ROM I've ever installed, and with the clock slowed down to 1,026, conservative governor and other power tweaks, I'm getting the best battery life I've ever gotten on any rom on this phone.
Very Very pleased. Install and dontate!

[Q] Most stable battery efficient ROM?

I'm fixing a phone for someone. At first it was stock and crashed very often about once every 10 minutes of use, so I flashed cyanogenmod but the battery life is much worse. I just need a good stable battery efficient ROM and the other features like ICS don't matter much. Any suggestions?

Try them, and find out for yourself. Everyone seems to get different results, different preferences and different usage of the device.

The problem with that is that I'm not using the device so I can't test out several roms during the day and find out what has good battery life.

I didn't ask what's the most stable, battery efficient ROM on SGSII forum when my friend gave me a day. Flash a ROM, give it to your friend and see what he thinks of it, then if he doesn't like it then flash another ROM.
It's all about preference, you might like SCOM ROM (GB) but your friend might prefer CyanogenMod9 (ICS) more. But if your really looking towards battery life go for Gingerbread ROM.

You guys really can't just tell me what works for you or what you had experience with? I already tried to help once and it takes weeks before this person has free time to give me their phone to try and fix it again.
It's not like this phone has different hardware from all the rest of the galaxy s 4g's and they are dependent on the phone. They should all work the same so it shouldn't be such a big deal to ask for some measly suggestions.

Not everyone is going to get the same results from the same rom. It all depends on your usage.

Please state with reasons and what variables there are and what the tradeoffs are or you are talking out of your ass. Of course people's usages vary, but if you keep your usage constant while changing roms like you typically would or have a composite number than your can compare roms for battery life.
It's seriously not that hard to quantify which roms last longer on battery. This is ridiculous.

If it's that easy to you (may be?), do the testing and post the results. Document and publish your methodology so it can be peer reviewed. Please keep it up to date as ROMs are updated.
I look forward to your findings.

I just told you that gingerbread roms have great battery life.

There is no definitive answer bro. I dont get the same battery life as jeffsf or FBis251 on AOKP. And neither one of them get the same battery life. It really does depend on each phone and the users habits of use.
Im going ahead and reporting this thread because the community here dislikes these threads. They never end well and you have POHR people being belligerent .

As I've said before, usages vary but it's pretty reasonable to think that some people have used a few roms while keeping their usage constant. What makes it frustrating is that the people on this thread spew some faux wisdom that it's impossible to compare which it isn't.

I've had pretty good battery life so far with HebMIUI when it comes to ICS. Of course, GB ROMS such as Valhalla Final, Valhalla Black, and Octane are known for the excellent battery life.

All of this is far too subjective. Try them and make your own decision.

[Q] Custom ROM vs Stock ROM (thoughts/suggestions/etc)

One of the reasons I purchased the Nexus 5 is because it is Android at is purest. After I got the phone, I used it for a while without rooting it, until I needed to use an app that required root. So about a month after having the phone, I rooted it. Now I am finding some things that KitKat doesn't let you customize. They are all minor interface things but I'm sure everyone here can relate... I want more customization. So, here are my questions:
How long before you rooted and/or flashed a custom ROM?
Are you happy with the stability of your custom ROM?
Any difference in battery life?
Which custom ROM are you using and why?

1. Day one I rooted.
2. Most roms on a nexus are stable... Except maybe some nighties, which are works in progress.
3. Roms have very little impact on battery life.... So don't use that as a deciding point.
4. Mostly you'll just get a list of the most popular roms when you ask that. But I'll say Graviton. Cause it's a little different than some... And the Dev is very active in his rom thread. Always a good thing.
5. questions go in Q&A. For future reference. ?

Please post questions in the Q&A section
Thread moved

I have rooted the device, the first day I got it, uninstalled bloatware and other crap, installed *my* favorite Apple and I am happy. I did Not finden *any* thing, which could not be customized. What specific point are you missing in customization? My device runs fine, I use Greenify app, so the battery runs about 48 to 60 hours depending on the programs I use. Video is more battery consuming that making a call of course.

There's another alternative in case you have a dilemma whether to stay on or leave stock ROM. Check out my GravityBox project (xposed module).

Wow, I just started using Xposed on my tablet but didn't realize it was capable of all of this. Definitely going to try this out before flashing a new ROM.
P.S. Sorry, not sure what I was thinking... for some reason, I thought I was posting in Q&A.

I left it for 3 months. Then used xposed and gravity box to get the notification toggles the way they should be.
I shouldn't have to have it take me into settings to toggle data on and off.
Other than that stock is pretty well perfect for me.

Stock Nexus is Android at its purest... with Google apps and services added.

After the OTA images of Lollipop came out, I knew since I was rooted, I would have to do a manual install. So I'm back to stock (non-rooted). Right now, I don't see a reason to root. So far Lollipop 5.0 is serving it's purpose. Yet another huge step in the right direction by Google.

Flashed 5.0 factory images the day they came out, was not satisfied with the OS as a whole, so now flashed a custom ROM Mahdi till 5.x.x comes out or any AOSP 5.0 rom comes out.

AOSP 5.0 roms are already out.

I ordered mine Oct 31 last year. Unlocked the bootloader day one. Probably stayed stock for a bit, don't know how many custom ROMs were out at the start.
Stayed on Cataclysm for a long time, went to Purity. Flashed stock 5.0, was on that a few days and now a custom ROM again.

I know about that, no offense to the current rom builders but I was more like waiting for slimpop or cm12 or paranoid android roms. But I have a question most of the roms come with gapps built in them which i find confusing as no rom built from source should do that, or are they just themed or mod-ed stock roms?(which is the primary reason i haven't yet tried them out)

Which kernel

Hi,
Should I root my nexus 5?
I still have a year warranty so...
Which kernel should I flash then : Franco Kernel, or Code Blue Kernel?
I am running lollipop 5.0.1 stock right now. Screen on 1/4 brightness, no location and WiFi turned off when I don't use it. Know I am getting around 12h battery life with 2-3h screen on time, would one of the kernels help with battery life? And how much? Will it be worth to void my guarantee for it?
Thanks in advance!

Although Kernel devs will build in optimisations and efficiencies that will improve battery life, these are very, VERY tiny...and if 1 kernel has these optimisations, they likely all have.
People will often say "Kernel x is better than kernel y for battery life". This is actually wrong. Kernels respond to user settings. Setting up the governor to favour either battery life or performance is simple enough to do, you just have to do some learning. The reason people think Kernel x is better than y is because developers set their kernels up with their preferred governor settings. This is what we refer to as out-of-the-box settings. The out-of-the-box settings for kernel x may well produce better battery results than the out-of-the-box settings for kernel y, which favour performance. The fact is, you as the user have the ability to tune kernel x or y to perform the same, be that battery or performance - so start learning how to do this yourselves - that way, you can choose the kernel based on the FEATURES you want, and not the fictional performance benefits of one kernel over another.

Hi!
Thanks for taking your time and your explanation mate, you really helped me out! Think I am gonna see for Franco kernel, cause there are more users and more tweaking options to fit my wills.
Thanks again!
