I rooted to get rid of bloatware and my main reason for AOSP ROM was to get away from sense messed up BT stack (want to use Wii controller), but if this is what I'm up against I will stick with a sense ROM (probably go back with fresh had with my hero and it worked well). is this the norm for ASOP? Ive seen other post about better battery life on sense ROMs. is it just how it handle the system different I already followed this one here:
http://forum.xda-developers.com/showthread.php?p=19474607#post19474607
And couldn't get it working fully. Does anyone have any other suggestion. Different ROMs, kernels, setting I could try as a last shot. Would prefer a basic ASOP with good battery life, and most stuff working (don't know if that's to much to ask).
Thanks in advance.
I don't think that 5 hours of battery life should be considered normal for any ROM. If that is all you get from a phone then something is wrong.
Have you tried wiping battery stats in recovery? Sometimes the software just reads the battery level incorrectly. It would have to be pretty far off to claim you were at 10% after only 5 hours but who knows...
You can google it but the typical process is to charge it up to 100%, wipe battery stats, then reboot and unplug. Drain the phone until it's absolutely dead then you charge it fully again and it should read the battery level more accurately. Apparently it is bad for Lithium Ion batteries to be drained completely though, so it is not recommended to do this often as it can shorten the overall performance of your battery.
I haven't seen much of a difference in my battery life using Cyanogenmod 7 or MikG (currently running 2.58 but 2.60 is out now). I personally really prefer sense ROMs and MikG is definitely the best one I have used. Give it a shot. I have gotten 60 hours of battery life on the stock Sense ROM (granted, it was with almost no use) and over 30 hours with pretty decent usage. I posted some youtube videos to demonstrate this since I figured everyone would claim I doctored photos:
over 50 hours (wound up being 60 hours by the time I finally unplugged):

32 hours:
http://www.youtube.com/watch?v=SPqtsRDRYEs
I have since moved to MikG but I pushed my battery again last weekend and got another 30+ hours of it. I'm extremely happy with my battery life!
I am sticking with MikG over CM7...I have too many issues with CM7 and there just isn't enough to keep me there. I was going to write up a huge post about that now.
yea i actually did wipe that stats. Ill probably just do a full wipe and start fresh with sense rom and see where it goes. What are some advantages of mikG any features that make it special over others? What version of sense does it have? Im downloading right now. is there a info page of what all it includes? i couldn't find much info for it.

Im in the same boat some what, but I will say your time should be better with no use. Im not getting huge battery increases with aosp roms when using the phone. Im better off with the stuff that worked well on sense roms for me with no tinkering (gps, slow sd speeds, updating prls, etc)
Im convinced the people that claim these lengthy phone hours dont use their phone besides texting much even if they say otherwise. Most screen shots I see rarely even have voice calls registering. I think the best way for "me" to get a full day is to buy an extended battery. Im not on wifi all day, Im in and out of low signal areas. I need to keep data on due to emails for work. Maybe Ill run into a miracle rom and kernel, lol
I do like the classic rom which I backed up and I will try some others today (fusion/hyrbid ex1)

I always wind up back on this ROM. I just think it looks beautiful, it is fast, and it just works. I use GO launcher EX as my launcher by the way. I highly recommend it no matter what ROM you use.

I totally agree with you with is why if you watch my second video posted above, I actually go into the usage screen and tap on the things to show what I am using. 50 minutes of voice calls, 25 minutes of words with friends, 41 minutes of GPS, Bluetooth on 100% of the time, etc.
But typically when I see those you tube videos I see people saying they were using their phone heavily and got 25 hours out of it. If you look closely in their battery stats screen though, you'll see that cell standby was the top battery user. That refutes the heavy usage claim right there!

How is this possible? I'm on 1500 stock Mah battery on a fresh sense rom 4.3.2 my battery wont last that long even if I reset battery stats. But running on cm7 with stock it does pretty well avaerage 15+ hrs depending my usage.

I put FreshEvo and it looks like battery is holding up well. I got MikG tp play around with..(it does look beautiful). A few quick question about it.
1. Does it have the native hotspot app unlocked or just wireless tether?
2. Has CarrierID been removed or disabled?
3. Should I use the default kernel in the rom, or is there a particular one you use.
Thanks,

2. I don't even know what you're asking here sorry. Do you mean you want to use it on another carrier besides Sprint? If so I have no idea...maybe post your question on themikmik forums.
3. I use whatever kernel MikG comes with. Some people like to flash other ones, but I have never messed with new kernels, regardless of the ROM I'm using.

Great! I have found MikG to be awesome so I'm glad it works for you too. If you want to upload a screenshot then tap the power button and quickly hit home. It should take a screenshot. Then if you want to share it you can go the gallery app and tap the share icon (circle with 2 arrows). If you want to attach it to a post here from your phone (xda app) then start a message and then tap the more button. You should be able to attach something from the gallery.
I just posted pretty much the same info at themikmik.com but it was more detailed. I'm on my phone right now but I'll go copy that link and paste it into an edit here.

Senseless MikG 2.9 has gotten me over 2 days of moderate usage consistently. This however does not include 4G since I can't get a signal anywhere >_<
I use CM7.1 + SavagedZen (latest) SBC (BFS) and get between 40 and 60 hours depending on usage.
I am also using the Sprint extended battery, however. By my estimation, this accounts for roughly 8 - 10 of those hours.
The kernel made a HUGE difference. Tiamat 3.3.7 was only getting me about 20 hours tops.
Phone is also undervolted, and supercharged. No overclocking or underclocking. I am incredibly pleased with this phone - definitely can't switch phones unless I know that I can get something remotely close in terms of battery life!

Simple solution, sell or return the Evo and get a 2nd generation windows phone mango device such as the Focus S or Titan or Lumina series, or even a first Gen such as the Focus. No more constant rom flashes, force closes, lag, and horrible battery life.

Hi.
I have installed PA 3 (15 FEB Build) + Franco Kernel r72 (I heard about people talking about the r80 but i cant find it..).
I have been looking for a guide for this kernel, is the first time I flash one and people says battery life is awesome, but I cant agree with other people. So far I have noticed worst battery life, maybe because the r72 is not for 4.2.2, maybe because I need to do something else apart of flashing the kernel?, I bought the app, and the only changes I have made are some in the screen color and put the max. cpu to less 1188 MHz, i thought that putting it less will give me better battery life but it didn't.
So far I had better battery stats with stock, for example: Last night I completely discharge then charge it full and let it rest the hall night to see how the battery will be.. With franco it jumps from 100% to 85% when i saw it in the morning (I just did a little of web browsing before going to sleep but it doesnt mean 15% less??) and with PA original kernel (They use the stock kernel with some modifications) From 100% to 99%. I mean is a huge difference, maybe I'm doing something wrong or something but that cant be good.
I'm not saying that franco kernel is bad, what I would like to know is, if I need to do some adjustment in the app to get a good battery life. I have heard of undervolting but i cant find a guide for that and franco kernel.
I'm really new to all of this so any help would be appreciate
Attachments: 84% Was when i woke up, cheking all the stuff and taking screenshots then it was 80% you can see it in the attachtments and the phone idle time too.

R80 is a test kernel that Franco release a couple days ago. If you ever read the OP, you'll find the link here.
http://forum.xda-developers.com/showthread.php?t=2002782
It's even written in bold letters "Test versions (if you don't know what this is PLEASE don't flash or ask what inside)"
And here's the link from the OP, http://minooch.com/franciscofranco/Nexus4/tests/
From time to time Franco likes to test a kernel that he just implemented before putting it off as a final release. For final nightly release, you can also find the link in the OP. http://forum.xda-developers.com/showthread.php?t=2002782
It's also written in bold letters "DOWNLOAD". There are two kernel versions now. For whatever android version you're using choose the correct link and download the latest one.
Last night, Franco released a nightly (r82) for verison 4.2.2.
You can find it here in the OP like I just told you. There's a .img file to push the kernel via command prompt but there's also a zip file if you click the link when you are in the 4.2.2 download link.
Next time, you should really take your time and read the thread. People will bash or ignore you.
Have fun and good luck!
P.S You're complaining about battery life and I noticed you didn't include that you have tried undervolting the frequencies. Undervolting will help you increase battery life if not a lot it should be an improvement.

Thanks a lot, and I noticed that part but I didnt think of it. I'm really new to all of this of flashing so this: "(if you don't know what this is PLEASE don't flash or ask what inside)" , just make me focus on the official release in the zips sections
Actually my question is if there's any guide on how to undervolt/increase battery life in this kernel, is the first kernel I've flashed so I dont have experience with voltages and things like that.

There's no official guide. It's actually pretty simple.
But first you will need to find out what type of CPU bin you are using. What is that you say? I will try to explain it with the best of my knowledge.
Well, it's quite obvious that we have the same Snapdragon chip but not quite the same. Each one is somehow made differently based on it's quality. There are a few types, slow, nominal, fast and faster chips. What are the difference? For one, I know that they all have different voltages for each frequency and the quality of the chip will determine how much you can undervolt.
From here I am going to teach you how to find which chip you are using, you can follow this guide on the very very top section of the page.
http://forum.xda-developers.com/showthread.php?t=2048739
Second, you will need to download an app in the Play Store called "terminal emulator" (Link below).
https://play.google.com/store/apps/...251bGwsMSwxLDMsImphY2twYWwuYW5kcm9pZHRlcm0iXQ..
Here's how to find out the CPU bin:
1. Go to the app once you have finished installing it.
2. Type in "SU" to request Superuser root action
3. Type this in: "dmesg | grep PVS" (Without quotation marks) -----> http://forum.xda-developers.com/showthread.php?p=35547734&highlight=terminal+cpu+bin#post35547734
4. Finally, you should get something like this: "[ 0.873920] acpuclk-8064 acpuclk-8064: ACPU PVS: FAST"
5. At the very end of the command, you can see that the CPU quality like above. It's a fast CPU.
If you have a FAST cpu bin like 90% of Nexus 4 owners, you can undervolt up to -100mV just to be safe. You can test it farther but if your phone reboots, that means the value that you have entered is not stable.
Here are some articles on undervolting on android:
http://bigfatreality.blogspot.com/2012/03/guide-to-undervolt-android-safely.html
http://www.android.net/forum/android-rooting/58117-droid-x-guide-undervolting-guide.html
I hope this helped you in some way. Good luck!
P.S In addition to the Franco's test kernels, you can always wait until the official nightly release. Franco releases them when testing is complete. But it's nice to see what in store for us when the official nightly comes out. LOL

Hey. So I wanted to buy the nexus 4 , and then I've heard that the battery life is suck.
I found out that it could be fixed by installing a custom kernel.
I'd like to apply a cusom kernel
that saves -Alot- of battery , doesnt change anyting specific but the battery usage.
and to still stay with the Original Rom.
Any suggestions? Thanks.

try them all out, they are all good. the thing is, all our devices react differently, and all our usages vary with as many users as there are. so the only way that you would find YOUR perfect kernel that YOUR device likes the best is to try them all out. it takes seconds to flash, so time isnt an issue. try one every few days, youll find the one thats for you.

OK... but all the kernel changes something in the rom. I would like to keep my rom exactly the way it is , exept from the battery usage.

You can flash any kernel you want, and the ROM will stay the same. The kernel operates "under the hood" (the engine), while the ROM is what you see (rest of the car, to use that analogy). You can use an app called Trickster Mod to tweak kernel settings. Be sure to know what you're doing though, and keep a backup just in case.
Also, be sure if you flash faux or trinity kernel (that I know of), that you flash on top of a stock kernel/reset kernel. If you flash any of those on top of another custom kernel, you could get in trouble (because of the way the kernels are installed).
And the stock kernel is really not as bad as people make it out to be.
Sure custom will usually be better. But stock is not that bad. All those reports of horrid battery life I really don't know what the heck they are doing to be honest.
I used it for a while. And the other nexus 4 in the house is bone stock. It gets off the charger at 530am and needs to be charged around 4pm with around 4 hrs of screen time and 45 mins or so of candy crush.

You can flash any kernel you want, and the ROM will stay the same. The kernel operates "under the hood" (the engine), while the ROM is what you see (rest of the car, to use that analogy). You can use an app called Trickster Mod to tweak kernel settings. Be sure to know what you're doing though, and keep a backup just in case.
Also, be sure if you flash faux or trinity kernel (that I know of), that you flash on top of a stock kernel/reset kernel. If you flash any of those on top of another custom kernel, you could get in trouble (because of the way the kernels are installed).

And the stock kernel is really not as bad as people make it out to be.
Sure custom will usually be better. But stock is not that bad. All those reports of horrid battery life I really don't know what the heck they are doing to be honest.

Now that the battery life is improved on 4.3 JB version , I wont be needed to a custom kernel. Thanks alot.
howdy ya'll
Like most people I've been here a few years lurkin, but now have a problem I can't fix and so signed up for some help
I've installed vrtoxin rom 3.0 (android 6.0 marshmellow) and I am getting appauling battery life
I've done a complete wipe and just installed the ROM itself (no Gapps) for troubleshooting.
I'l get about 5 hours of battery life (not screen time, actuall just sitting there going flat battery life) a quick look into the battery stats and it says the "android system" is keeping it awake
here have some screen shots for references... I've done some searching on the vrtoxin page but no one else seems to be having this problem (or my searching skills are sub par)
any help will be apreciated and thank you in advance for your time, I really really REALLY love this rom, but I want to figure out what wakelock is stopping it from going to sleep.
sorry according to xda, im not allowed to share external photo links as I havent done 10 posts or something....... soooo thats helpfull. I will post them up after I have donme 10 posts I guess.......
hmmmmm interesting,
Ive installed AICP (android 5.1.1) and it seems to be doing the same thing, could this be a hardware issue?
before installation I did a full wipe (data, system , cache)
and its doing the same thing, battery is going down at an alarming rate (about 30% and hour with no on screen time)
these both use different kernels but I might try flash a custom kernel and see what happens
Anyone got any suggestions?
Try an app like this
https://play.google.com/store/apps/details?id=com.uzumapps.wakelockdetector&hl=en_GB
CM13 is a nice MM ROM too with good battery life as an alternative ROM
If Android system is the problem and not an app, it's likely the ROM itself, custom ROMs often have worse battery life
Check the CPU is throttling down, and the governor is not set to performance where it keeps the CPU @ max clocks all the time
Please post your battery life in stock marshmallow,stock nougut,RR,AICP and other roms.
So we can compare them.

There is really nothing one size fits all kind of thing. Try these different ROMs for yourself to see what works best for you. It's hard to see which has better battery life since different users will have different usage stats.
I have to agree... One person might get great battery on RR and terrible on AICP, the next person the opposite. The only to really tell which one gets the best battery in your situation is to try them.
Data is too scattered to determine which ROM provides the best battery life. You see people getting all day battery life with different kernels, tweaks, usage, etc

I'm not trying to bash your post but TBH, any comparison you make from others is practically useless. As mentioned, people have different experiences on custom ROMs. One specific ROM might have excellent battery life on one phone and have horrible battery life on another of the same model. But there is an even more important factor that makes comparing across ROMs just as useless... Everyone uses their phone differently. Not just with apps they install, but with the features of a ROM they they decide to enable or not.
On that note, if you are considering a custom ROM, the best way to determine if it is right for you is simply to try them. Make backups that way you can revert back to the one you decide is best.
I know that every user use their phone differently. I don't know what made you guys think i don't know that. But what i am trying to compare is not overall battery life but battery life based on individual usage. Like when some one use that rom for only calls and get a lot of stand by time how much battery it drains. from that i can know how much battery it drains when kept idle. Same goes for using wifi or using mobile data , watching YouTube or reading PDF. I want to know how much battery that rom uses on what usage.
Sorry for my bad English. I hope you guys can understand what i am trying to say.

I understand this. But I think it would be easier to try for yourself, because to get say, me to try say 4 different ROMs, same usage, and then report back to you would be more time consuming than you trying for yourself.
I know you know that every user is different but the same user trying different ROMs for you just doesn't make sense.

Referencing individual usage as you have, along with any specific ROM across devices, you are not going to get consistent results. I understand you are trying to consolidate this data on one post, but there are to many variables involved.
To highlight: I could run AICP on my XT1575 with a clean install and no extra apps installed and make only calls and I might get excellent battery life on standby. But another XT1575 owner can do the exact same setup, make the same number and times of calls and get horrible battery life. This pretty much goes for any custom ROM, especially those not based on stock. This does not even account for differences in MM vs N. This also does not account for an update to a ROM screwing up battery life and the next one may fix it (which is relatively common). I've even seen where someone gets great battery life up to a certain update and thereafter it sucks, but another can experience the opposite.
And once again, individual usage still matters as individuals will have different apps installed, which can take up varying amounts of battery depending on background processes and syncing. This affects standby time and SOT to some degree. Also do not forget that the chipset on this phone is prone to negative affects on battery depending on cell signal strength, so that is another kink in observing and comparing battery life across users.
Ultimately, the best way to determine what gives you the best battery life is too rest ROMs for yourself and your specific usages.

I am not saying anyone to try different roms for me. I was just wanting them to post battery stat of the rom they use as their daily driver.

Yes ok. So we should be on the same page about different users using their devices differently. So if user A posts about say ROM B, and user B posts about ROM A, you know you can't compare. I would post my stats with RR but you couldn't compare to someone posting AICP stats as we are different users. The only way to be even somewhat accurate would be to get the same user to try different ROMs. Which you can do. Honestly just try the different ROMs! I will say with my experience though DU has not had the greatest battery life.

Well said!
@yk1999 As stated above as well as in my post, you just can't compare experiences of users across multiple devices and ROMs as there are to many variables involved. We understand what you are asking and we are telling you that there is only one way for you to get the information you are looking for. The only way for you to figure out what will have the best battery life in YOUR situation (how a ROM operates on YOUR specific device, YOUR selection of apps, and YOUR specific usage scenarios) is to test the ROMs for yourself.
Maybe there should be an app saving battery stats for the current ROM (internal storage or personal cloud), and comparing these personal stats with previous stats made when you had another ROM installed.
Of course there are other variables that affect the battery stats (like the apps installed, or the apps you actually open in a battery cycle) but at least the app would be able to list and compare battery stats on the same device and user.
Ie, I imagine a list like:
- ROM R1. Kernel K1. X1 apps installed. Battery rate: BR1
- ROM R1. Kernel K2. X1 apps installed. Battery rate: BR2
- ROM R2. Kernel K1. X1 apps installed. Battery rate: BR3
...
It could be able to group by Android version,...
I haven't found an app doing this. Do you know an app doing it? And, do you think this app would make any sense?
