[Q] Battery Rom Question.

Hellos guys I would like to know wich Rom out there has the best battery life.??? Im running the latest juggernaut..thanks.

I would say dewizzled

I'm not sure if you can just say best battery life is XXX as everyone's usage patterns are different and different aspects drain the battery faster than others. I have found Dewizzed to give me the best life out of all of the ones I've tried, but I don't get near the time that many post in that thread. The one difference is that when they post their usage stats I never see "Voice Calls" in the top half of the apps using battery, whereas if I look at mine right now Voice calls is #1 at 53% and Display is #2 at 18%. I use my phone heavily as a phone during the workweek, others use it as a media device, others gaming...you get the idea.
Try Dewizzed and try a couple of others. It's easy to flash and then restore or go back to one that works better for you (plus the geek in me thinkgs that is fun too).

How about NO ROM? I am using stock right now, but using Faux #009 mainstream Kernel. I was running Jugg 4.1 before, but went back to stock after having some issues with texts not going through.

Im going to try some of the roms.. I
Thanks guys

WOW! thats pretty impressive. what's your time on display?

I was wondering the same thing. But more along the lines of which rom kernel combo people are running. Now to hijack original posters thread, but if people could also put what kernel they are running too. The best I ever got was BeastMod with Synergy, but once he left the building I don't feel like any of the other ones have been as good.

That tells us little, click on display and show us how much time the display has actually been on

From my experience, it is not necessarily the rom that effects the battery life as much as the kernel does. Every rom I have installed I end up changing the kernel to synergy 10 and see a big increase in battery life.

+1 on the syngery kernel.

+1 on Synergy kernel
Juggernaut was OK for battery life, much better than stock, but I couldn't be any happier than with BeastMOD and synergy kernel.

Display time on and brightness? From the graph it doesn't seem like you used the phone for too much and we don't know how bright your screen was, time on voice calls and any other applications. Why is it that people don't know how to post battery life correctly? Your wifi was on most of the time and wifi uses less battery than data connectivity plus we don't know the type of reception you were receiving. Edge consumes less battery than 3G. These are all factors that need to be taken into consideration to draw a clear conclusion on your battery life.

Custom Kernel - What do you say?

Hi everyone, for a long time i see ppl claiming their phone last longer due to a custom kernel.
Normally i read they saying "i could never make my phone lasting with 2hs screen on or lasting for 2 days".
Anyway, its obviously that this will depend 100% what ppl do with their phone accordingly to apps, widgets, syncing, etc.
For me, normally i have around 3 and a half hour screen on and around 1 day and a half to 2 days.
I do use WiFi and 3G alot... browsing, gaming, texting, etc.
My point is that i belive ppl have a placebo effect. Custom kernel will give you faster response, OC ability and other advantages.
What do you guys say?
Attached are some screenshot from my 100% stock phone.

I just believe some of the little tweaks devs do to a custom kernel do make a difference.

I bag 4h30m on my gnex regularly.

Yea I totally agree that stock performs just as well in the battery life department. All I care about is having root.
Sent from my Galaxy Nexus using xda app-developers app

Your battery life won't really get better than that. I really agree that there's often a placebo effect in switching roms/kernels, i only use a different kernel for color settings volume boost via Francos app. Stick with stock though I'd say, but of course it's always nice to try out kernels, despite the placebo effect.
Speaking of which though, I'm performing a real life test seeing which governors on my kernel work best for battery life. I simply switch then lol at my screen on time and see if it's improved, I'm assuming hotplugx will win, so we'll see. Interactive is still a great balanced on though.
Sent from my Galaxy Nexus using Tapatalk 2

It made a difference for me personally, because I wasn't getting very good battery life at all with the stock kernel. The other tweaks were also a pretty good bonus.
You're getting pretty great battery life as is though, I wouldn't worry too much about changing to a custom kernel if you're consistently getting numbers like those.

Thanks everybody for the feedback. I guess we are all at the same page.

Battery life or not but performance of the phone definitely improves with custom kernels... Asphalt 7 use to lag a bit on stock JRO03C but after trying Franco kernel Milestone 6 no lag or reboots whatsoever..
In fact I have a placebo that custom kernels reduce battery life

Worth it for the small performance improvements alone but I do get a little better battery life.
Even a few percent better is better than nothing when you sit in a building with poor reception and your battery takes a hit from your phone having a low signal

Personally, I run trinity...
Mostly for it's colors but I did seem to go from 1 day to 2 days without charging after the switch (placebo...?)

My battery suddenly dropped from 15% to 0% on Milestone 6... Now I'm back on stock custom kernels are like 3rd party engine mods on a car..

3+ hours screen on time, 12+ hours standby. I didn't think it was possible, my battery bad been draining pretty quickly. I think the key this time was that I was on WiFi all day.

no sync because i don't have the data to go syncing the whole day, auto brightness, 3g outside, wifi at home. Web browsing only, i don't play games on my phone, it's reserved for my computer.

Stock kernel, stock ROM. Turn off auto sync unless you are connected to a wifi hotspot. This will give you 3 hours screen on time and 12+ hours uptime. I have 3 email accounts set up, but they do not sync automatically. I manually check my email in the am, at lunch, and evening.
Stock kernel, unless you can't help but obsess about making your phone "fast". If you want fast, go into Development Options within Settings and turn off all animations, then install a launcher like Nova and turn animations to "faster than light".
I used to flash all kinds of mods on my phone and I realized that was ALL I did with my phone, tinker and troubleshoot it. I will only unlock and root my phone if we stop getting the latest OS updates. In the meantime, nothing is so wrong with the stock kernel and rom that should make you install Bob's OS. But you know, that's the beauty of Android. You can decide what you do with your phone. Hope my point of view makes you reconsider flashing any custom software.

My biggest problem is screen time. I can never get more than 1.5 hours on a single charge, that lasts 8 hours at the max. Also, it's a Verizon gnex

Try to install Better battery stat app (which is free on XDA), let it run a few hours and post results here.
Also, which brightness level are you using? Rom, Kernel? Custom color settings?

Auto brightness no custom colors and check post #1 for rom and kernel

-Get a new battery
-Change kernels
-Change ROMs
-Change Governors, CPU frequency speeds, and/or I/O schedulers
-Use a 4.2+ ROM and kernel that will insure you get a GPS lock
-Check for any rogue apps that continuously run in the background
-When these aren't being used, turn these off: Data, Bluetooth, Wifi, Sync, Location, and autobrightness. use Lux for autobrightness, both free and donate in the play store.
-Buy an extended battery (I bought the Seidio 3800MaH battery, worth the money.
Hope I helped!

I had similar issues and imo it was all related to the 4.2.1 roms+kernel. My phone lasted 6-8h. It didn't matter if i used it or not the battery life was terrible. After switching a lot of kernels the latest faux123 was the best.
I really had bad charging if i would use my phone while charging it would not charge and it would sometimes also lose percentage of was scary. I changed my adapter batteries with a friend he is running 4.1.2 blackbean and everything was okay but mine still had problems. After flashing latest faux123 kernel it is as i said working really good. Btw im a heavy user.

Is that for you battery problem?
That looks really normal but yeah.. I have much better battery life! D
68% of battery left, Nexus have been in idle 7 hours 1min, screen on 60 min...
Change ROM, I recommend stock ROM Takju/Yakju
Use stock kernel.
Try different radio basebands, I recommend the XXLH1 radio baseband for Takju/Yakju build (JB 4.2.1)
Disable apps which runs in background what you don't even use.. e.g. "Currents"

I had the same problem and I solved it changing rom and kernel

So I've got a recommendation for faux123 and stock. Remember that this is a Verizon gnex. Any other good kernels?

Trinity is having troubles all over the place with sods and trinity was always my so to say daily driver kernel. Franco also had that problems like trinity but his latest kernel is good but that battery drain remained. Anarkia's purity kernel is good his latest version is v11 but lot of people say v5 was/is the best. Leankernel was giving me some serious problems. Faux123 gave a bootloop before but his latest release b3 i think is the bomb.
All these kernels were tested on three roms xenonhd, xylon (imho most packed and flawless rom currently) and now i'm beta testing blackbean7. The problem with kernel+rom is that our devices are not the sam, so faux may good for me but bad for you or vice versa. Just try it out first and then go from there flashing other kernels.

I am having almost identical issues. I have gone to stock and changed kernels, roms, radios you name it, battery life stayed about the same 6-8 hrs. Will check out lux and faux kernel

Post a Screenshot of your battery drain in the settings and give details about your setup. And what is fast in your opinion? 1% /hour?
Maybe you should buy the extended battery kit?

try flashing different kernels and see which one suits u the best.every phone is different.u may also wanna underclock and undervolt. also change the rom may b if changing kernel doesnot work.ine suggestion.XenonHD rom with its stock kernel.

The stock battery is a joke at 1800 and the extended is 2100...I had both and both sucked although the 2100 was a lil better. I have the 3800 Seiko battery now and that will last me all day. Makes the phone thicker but its better then charging all day and worrying about what's killing your battery.

Turn off features when not being used like data NFC GPS.
Also avoid auto task killers

How much does it drain in one hour? Battery drain depends on many factors. The mains ones would be what kernel and ROM you are running as well as what "features" you have turned on. For example I am running CM10.1 with the stock CM kernel and I usually get around 16-18 hours of battery life with 1.5-2 hours of screen time.. that is with all of the features (gps, NFC, etc.) turned OFF.

How on earth can you drain a 3800mAh battery in one day? Nonstop internet radio AND 3d gaming on full display brightness?

I am currently using PA rom with franco kernel. Normal day = roughly 13-15 hours ish.
By normal day I mean around 30 minutes of talk time, about 1 hour ish web browsing and like what, 30 minutes ish of youtube? Of course, sometimes I am free and end up playing games on it for couple hours lol, but the stock battery seems to be plenty enough to me.

My battery makes it about 15-17 hours,with about 1 hour gaming,1 hour browsing and talk time around 1,5 hours...Xylon + Purity Kernel!

It is what it is. This is Wi-Fi only on this charge:

Turn data off when not using it. You can download a widget for that.
Keep screen brightness down low.
If rooted use setcpu and choose a screen off profile of 350mhz maximum - I find this a real benefit.

You can see I turn wifi off unless I'm using it. The single line under "Charging" is when I plugged it in to copy about 60mb of music over. Took about 1 minute, so not exactly long enough to bump the percentage. The screen is almost always set to 25-30% brightness. The heaviest period of use was yesterday, when I was browsing the internet and downloading and installing some apps, so I haven't exactly been going hard on it.
Another thing I'd like to say is that this phone is less than a week old. We all know batteries degrade with time, so I'm sure the freshness of the device has something to do with my extended life. However, it is mostly because I'm using a stock based 4.1.2 rom. When I had Slimrom 4.2 on it, it was getting just over 24 hours, with a couple periods of fairly heavy use(playing games, downloading/installing all my apps on a new rom and getting everything set up the way I like it). If I were to baby it like I did yesterday and today, I'm sure I would see about 30 hours on 4.2.

ROM: Orion AOKP.
My only tweaks were to edit the build.prop file: WiFi supplement scan interval from 30 to 1800.
