Hi guys and gals (if exist)
I really love my HebMIUI ROM based on Erikmm's latest MIUI V4.
I injected it the latest Team Acid kernel and auto brightness mod and it seem to work flawlessly,
Problem is battery life is just not good enough to serve as a daily driver.
I intend to merge PIMP my ROM mod and DS's A.I when I have time, but I seem to miss something.
I'd be happy to get suggestions.
Here are some XDA version Better Battery Stats raw data snaps : (10x!)
Idk but actually, when I told u my battery was not good and I meant it just could last for a day lol...and I have never used it for more than a day w/o a charge even on GB so i dont think its bad...anw, just try all things u think its good cause its hard to say anything bout tweaks and battery life I think cause...IMO and from what I have been through, scripts and build.prop lines not really help much both performance or battery life...and even OC or UV

I use cMiui 2.8.10.
so I don't know about HebMIUI but i use that rom around 20hr w/o charging.
This rom base on Hefe kernel 0.8(I think)
I tested Hefe 0.8.1 kernel but 0.8 is better than 0.8.1 battery life.
I use cMiui 2.8.10. I think cMiui and Miui is almost same.
I love this rom. I waiting UPDATE. ^^
You can try this and flash rom again.

Hi Dao
I know what you mean..
we both are more than heavy users, not leaving the phone for a minute, so in that way, yes, even on Valhalla I barely made it through the day.
Here I get this issue even if I have no activity and that's what bugs me. Batt is draining no matter what the user does. That's why I shared this technical data presented in the pics.
Thanks MJMJ
I'm not looking for a replacement.
I love the original MIUI, tune and customize it and share it, here on xda, especially for Hebrew speakers, but not only.
Every ROM has his pros and cons. Cmiui is based on cm9 and miui is based on touchwiz. I prefer Miui as it is the original ROM and is generally considered more stable.
I might try Hefe kernel though.
I think problem is related to device awake status...

That your phone is running quite a bit at 100 MHz when I might expect that it be in deep sleep caught my eye. I suspect something is keeping your phone from deep sleep. I can't tell from the BBS you have posted as I'm not sure what you were doing during the time it was collecting stats. I find the BBS from when I'm not touching my phone and it is running on battery overnight perhaps the most valuable.
As far as Hefe 0.8.0 vs. 0.8.1 on battery life, you've completely fooled yourself if you believe you are finding a difference. Go ahead and pull a source diff -- it all is about the interface to sysfs so that external apps can control the UV/OC, not the kernel operation.

I an not a professional. I'm just user of this forum.
I found this about battery life.
about WIFI I advanced setup Keep Wi-Fi during sleep -> Only when pluggged in.
use both of this hefe 0.8 and 0.8.1.
0.8 is wifi off when phone lock.
but 0.8.1 is not.
and battery life is different.
I write just my experience on my larrow professional konwledge.
I'm sorry I can not understand about source code,Interface and UV/OC.
Just experience.
Anyway I love cMiui and Hefe kernel.
Hi
I put WiFi as always on (even on sleep) because I wanted to get whatsapp and work mail in real time. Otherwise I didn't get them in time. Perhaps this is it. I will try it as on only when connected and report.
I would also try it with and without auto brightness mod. Let me know what data do you need.

What follows is my opinion and it is not completely backed up by experimental evidence, so take it as you will.
I don't believe that any ROM or kernel can significantly improve battery life over any other "good" ROM or kernel. I do believe that there are ROMs and kernels out there than can significantly reduce battery life though.
In my opinion, the two biggest factors on battery life (past battery againg) are
How you use your phone
The applications you or the ROM have running
The most insight I have gained on battery life is running BetterBatteryStats on a "full" battery (unplugged) overnight, when I'm not interacting with the phone at all. As soon as you wake up, turn on the phone, go to BBS, and save a full log.
With a good ROM/kernel, I think you should be getting 90-95% "deep sleep" and no more than ~2% per hour (on a typical 1800-2300 mAh "advertised" capacity battery in good condition) drain. If you're not getting that, I'd look carefully at what is keeping your phone awake. If you have questions about interpreting the results, I know the BBS author and has a great thread where you can post your logs and get some feedback.
When the phone is running, it is my opinion that the screen consumes most of the current, assuming you're not a "gamer" or streaming music or other content. Running with dark themes in your apps (as you can), as well as keeping the brightness reasonably low (auto-brightness should help most users here), are good steps to take.
The GP2A light sensor reports 0.75 mA current consumption in Android, so I have a hard time believing that turning on auto-brightness is any worse that running at similar manual brightness levels. If the phone were to be able to run for 18 hours with the screen on (which we know it can't), it would be averaging ~100 mA -- the GP2A would account for less than 1% of that. Of course, that 0.75 mA may not be the correct number. I'm hoping to see if I can do some measurements on the screen drain at various brightness levels, as well as confirm that the GP2A draws minimal current itself. (Unfortunately, the I2C version of the light sensor used in the SGS4G and other phones does not seem to have a publicly available datasheet.)
I think that the way someone uses the phone has a significant impact, even day-over-day. I know that Hefe Kernel v0.8.0 and v0.8.1 have no meaningful differences in how power is managed. The report that one is noticeably different than the other says to me that day-to-day differences in how a phone is used, even when the owner thinks they are using it the same way, are perhaps more than may exepct.
Werd to your grandma!
Good post Jeff!
Good post Jeff.
Sometimes something as simple as playing a game and then switching to something else without the game exiting properly can do it. Once or twice a day on my PC, I'll go to my task manager and notice that IE or Chrome is still running despite my windows being closed. It's stuck in limbo. On a PC, it may suck up a bit of RAM or CPU cycles but if you have 6cores/8gb like me, you don't notice. Something like that on a phone can suck up battery life like a hog though.
Installing 1 badly coded app from the market can do it. Viewing webpages with more of a white background can affect battery life. There is a million things. It's like laptops. They may advertise 6hours battery life. Sure on the dimmest settings with the screen turned down and very few apps running. Stream and HD movie from Netflix and watch how that 6 hours turns into 2. lol.
Thnak you very much good informantion about battery life.
I understand what you say.
About my post.(I use cMiui and Hefe kernel 0.8)
WIFI I advanced setup Keep Wi-Fi during sleep -> Only when pluggged in.
I tested both of this hefe 0.8 and 0.8.1.
0.80 is wifi off when phone lock.
but 0.8.1 is not.
kernel version : 2.6.35.7-Hefe-ics-00044-g151987a and
2.6.35.7-Hefe-ics-00046-g83ec25b
Do I something worng?
I am not complain about your KERNEL or ROM.
I'm very glad you guys about good efect,time and everything for make good ROM and KERNEL.
Thanks again.
I don't think you did anything "wrong" at all!
The control of the WiFi is mainly a ROM thing. Android says "turn off the WiFi" and the kernel does it. I'm puzzled as to why you are seeing a difference. Since v0.8.0 and v0.8.1 are the same as far a WiFi goes, I suspect something else. Perhaps settings not "sticking" between flashes? If it happens again, logcat and dmesg might provide a clue as to why. If you do would you post in either the Hefe Kernel Q&A thread or the Q&A thread for your ROM?
Hi Jeff
Thanks for the detailed posts.
Did what you asked : got 96% after 7 hours of no use, no charge. Deep sleep is 98%.
So I come to conclusion that wifi is sucking up the battery on miui. It has very good reception and always shows full bars for all spots.

This is a mod that Erik put into his miui rom to attempt to fix the wifi "issue" on ics, the wifi signal is very strong (or maybe its just the wifi icon)

Hi
I installed 'Better WiFi' (from the creators of BBS) and set it to open wifi connection only when screen is on and keep it if there is network activity.
Left it at night and dropped from 65% to 35%.
I'm now sure WiFi is over draining when opened.

I haven't heard of that app before. My search-fu is failing me though, both here and in the Market. Where did you find it?

I don't want this to turn into a "my ROM is better" thread by any means... but as a newer ROM flasher, I was wondering how much difference a different ROM would have on battery life? I'm lucky to make it 8 hours on my Skyrocket right now even idling... and while I like the ROM I'm on now (Embryo), it's almost unusable as a device this way for me.
Thoughts?
ROMs definitely have an effect on your battery life, as they govern what's running in the background and how the system operates. Some ROMs are optimized for battery life, and some are optimized for performance. The OP and ROM thread will usually tell you which is which.
That said, if you're only getting 8 hours of battery life on Embryo 5, there's something else going on. Check the link in my signature for information on hunting down and wiping out wakelocks, and consider underclocking/undervolting and changing the governor.

you should check out the battery life help thread as it has almost every possible detail of enhance your phone battery performance. when im running embryo i always get around 22 hr with 2 hrs on screen so there something your missing. and every rom with have different battery performance not all because of the tweaks and rom enhancers but because of the user. a person who is surfing the web all day with little phone and text will easily drain battery. but a person who mainly running music social browsing talk text can easily get longer battery life.
No offense man but if embryo's rom is considered "unusable" then use another rom
Hey im looking for a rom that is great on battery. I just got up an hour ago and my battery is already at 90%. I feel like its going down too fast. Im using Purity rom with greenify.
Hi,
Better is to try by yourself, battery life is mainly based on your own settings and usage. If you have some rogue apps, bad network reception and your brightness at 100% (it's an example but I think you see what I mean).... Whatever the rom it will be the same thing.
1 hour... 90%... all depends of what kind of wackelocks you have, synchro, etc...
There is a ton of thread about battery life, take a look in them for help.
And: http://forum.xda-developers.com/showthread.php?t=2477889.
And also purity is awesome on battery life when I was using it... There are way too many factors to consider when talking battery life.

Stock Rom works very well. But it really does depend on the processes you run and the apps you install. Thus "best" becomes a relative term. If you have very bad network reception I'd recommend installing a kernel like Franco kernel. It stopped draining my battery even in areas of bad reception.
As it has been mentioned, battery life depends just as much on you and your usage / location / etc / etc.
Something tells me though that the roms that have in their title: Battery Saver Script might be something that focuses on what you are looking for. Just a shot in the dark...

One of those was literally on the front page of roms listed in Development.
I use omni rom with franco kernel r31 and I get 3 hours screen time with about 13 hours battery life most days. I use the internet a lot and text all day.
There are too many factors that affect battery life but also these threads are not allowed on XDA, as pointed out above. Try some out yourself and see which best suits your needs.

Recently I've been experiencing absolutely terrible battery life. I lose about 1% every five minutes with the screen on - sometimes even faster - and find myself increasingly unable to last a full (work) day without having to plug in at least once. My current ROM/Kernel are LolliGPE (http://forum.xda-developers.com/showthread.php?t=2716306) and Elite kernel from when I switched from stock Kit Kat back in December. It's worth noting that I haven't gotten around to updating either since their installation. I can't remember how my battery life was back in December nor before Lollipop, but I'm almost certain it was better than it was now.
My questions are:
What ROM/Kernel do you recommend for the best battery life?
Are there any apps I should check for and uninstall that drain battery?
In general, how can I increase my battery life?
Thanks!

1. Rom/kernel combinations in regards to battery life, or pretty much anything, is a completely subjective experience. You're better off trying different combinations for yourself and seeing what works best for you.
2. To see if you have any rogue apps, better battery stats probably does the best job showing what is using your battery. If an app is an issue it'll show you exactly what's causing it.
3. Best way to improve battery life is to monitor your battery stats with a battery monitor and try to control your wakelocks as much as possible. You can Google search exactly what process is keeping your phone awake and fix your problems one by one.
In my opinion, the three biggest things that truly affect battery life is mobile signal connection, Internet connection strength, and Google services such as Google now. Trying a different firmware version could increase your battery life as well as trying different rom/firmware combinations.
I'm running Adrenaline 1.2 with quantum kernel 1.25 on stock 4.4.4 firmware. I'm getting the best battery life I've ever had with that combo. Then again, in bright light where the screen has to run at full brightness and with a less than stellar signal, it will still eat through power pretty quickly. It's just the nature of the beast.
Odd I am stock non-root and see the best battery I have ever had with Android

After experiencing the same problem as yours with the two mentioned kernels, i seek for solution and found one. backup all my contacts, sms, call log, bookmarks, apps then i did a clean install of fluent rom based on sprint port cos i love lollipop and the two devices are similar in many ways. Surprisingly i get 6hours of usage with just 20% gone and at least about 3 -4 h screen on at the same time. so my advice is to try clean install.

Here are Buckmarble's own recommended settings with the Elite Kernel:
Governor: ragingmolasses
Ioscehd: fiops
Read ahead: 1024
UV: -24 across the board
2265 max 300 min
I use Trickster Mod to set these. I have heard that the frequencies don't stick, but I haven't bothered to check because battery life (running Fluent ROM 2.0) is stellar. I put my M8 on extreme powersave yesterday when it was at 100% because I'm testing a different handset and when I returned to the M8 late yesterday evening it was "all the way" down to 95%.
I know there are other threads to search I was just asking really quick how are people getting 3-4 hour SOT? I have a brand new battery running lean 5.1.1 LMY48 tried elemental and racwr kernels most settings stock and by battery life is terrible with 2hrs top SOT. Kernel settings are stock and device settings are stock I'm not looking for a huge gain just seems something is not right. I have tried different roms ect, wakeloxk detector just always shows Google as top user but nothing else crazy.
