I was talking to DoomLord about the infamous battery drain hunt and we got to discussing about ways to pinpoint the issue.
At some point, I mentioned an app that I swear by, BetterBatteryStats, by chamomix.
So, DoomLord encouraged me to start this thread to provide info about how to effectively use this app to accurately locate causes of battery drain issue.
This is very important for users who want to evaluate kernels' performance on that department, but it doesn't stop there.
You can use this app to see if any application you installed is acting up and keeping your phone awake, for example.
Before proceeding with this guide, I have to mention that BetterBatteryStats is given away for FREE for all XDA users (do not redistribute though) and there is also a paid version on the Market for people who wish to support the developer. I bought this app and I am sure that if you read this guide, by the end, you are going to want to do the same! Thanks chamomix!
Step 1:
Download the app from this post for free, or buy it from the Market.
Step 2:
So, what is all these???
Don't panic! First, let's set it up in a way that it'll make things less complicated.
Launch the app and hit the Menu button, then select Preferences.
DISPLAY:
Make sure Filter stats is checked.
Hide time since stat begin should be unchecked.
Hide graph bars also unchecked.
DEFAULTS:
Default stat: It can be anything. This is what you will first see when you launch the app. I have set it to Other, so I can take a quick glance at how long the phone was asleep and how long the screen was on everytime I open the app.
Default stat type: Better set it to Since charged. Again, this is just what you will see first. You can navigate through all the other stat and display times later.
WAKELOCK:
Wakelock pct of: Choose % of time awake minus time with screen on. This is VERY important. When a developer asks for reports on wakelocks, all users should use the same option, otherwise the stats vary and thus can be misleading and not helpful.
All the other settings are unimportant, tune them as you wish.

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Step 3:
Now what?
Now you have all the info you need about where did your battery go right there in front of you! I am going to help you interpret it.
We will use my phone usage as an example.
This is what I see when I launch the app:
So, my battery is at 97%, it was charged to 100% 21 minutes ago, it was awake for 20 minutes and the screen was on for 8 minutes.
That means that my phone was not sleeping even thought the screen was off for (20 - 8 =) 12 minutes.
Interesting...
Let's press the first dropdown menu and select Partial Wakelocks to figure it out.
Here's what I see:
Browser takes the first place with 2 minutes wakelock, then my Gmail sync with 1 minute and the rest with a lot less.
So, yeah, I left my browser on loading a webpage and the screen switched off.
Up to this point, we got a good idea of what app or process may be a battery drainer.
Moving on, we will investigate more advanced aspects of battery drain, useful for kernel testing and not only.
Step 4:
Is that all???
Oh no, hardly. You can see much more with this app.
Let's select Process from the first dropdown menu to see which processes used CPU power and when.
Here's what I see:
Notice how the bars can have 2 different colors.
Blue part of the bar means that the app/process used CPU power while the screen was on.
Red part of the bar means that the app/process used CPU power while the screen was off.
akmd8975 is the G-sensor (wherever you see akmd means the G-sensor), so for some reason it's using more processing power than it should. I am currently testing a new kernel, so I must inform the creator about it because this is the first time I see this in my stats.
(And that, my friends, is an example of how you should use all these for the general good. )
mediaserver is the process that imports all your media files to the gallery, usually it shows high usage after reboot, but after a while, it fades out (because there's a check for new media files upon every boot).
Now let's choose Kernel Wakelocks from the dropdown menu to see even more.
This is something you should leave to the kernel developer to interpret.
Most of these things are gibberish for us average users but can be VERY helpful to devs.
(I can safely say that the 3 first entries are related to charging and they only appear while you are charging the phone and shortly after. No need to get into deeper.)
Now let's take a look into the Alarms.
What are Alarms?
In layman's terms, Alarms in the Android system are those intents that wake up the phone in intervals or at a specific time. I am sure you can think of many apps that do that. Let's see which apps do that on my phone.
Hit Menu -> More -> Alarms
com.google.android.gsf is Google Apps Framework (your Gmail account, and related syncs and services).
android is the Android System itself which seems to be waking up my phone way too often (104 times in 20 minutes ). One more thing I should discuss with the kernel developer.
Step 5
I get it now! How can I gather all this info into one place?
By hitting menu button, selecting More -> Dump to File.
It will create a txt file on /sdcard named BetterBatteryStats-xxxx-xx-xx-xxxxxxx.txt (where the xxxxx indicate the date and time).
And the file will look somewhat like this when opened:
So, be it an app, a kernel or a ROM you are testing, you need this app!!!
As a co-creator of TEAM ROM for the X10, I have to tell you, I love all our users for their support, but sometimes I just want to scream when I see a post like this:
my battery drains fast why???
Click to expand...
Click to collapse
You see what the problem with this post is?
I CAN'T POSSIBLY KNOW WHY. It could be SO many things.
That's where BetterBatteryStats comes to the rescue!
Use it! You will help yourself and your beloved developers beyond words!
If you feel all this is "too complicated" for you and you don't want to bother, please consider how many complicated things developers are doing for you for free. You owe them at least decent reports. Am I right or am I right?
PS: If you liked this guide, don't forget to check another one about How to Report Force Closes in an App or ROM by PvyParts.

[i might need this one too]
Very good guide iridaki, thanks.
And about the BetterBatteryStats, I bought the Market version, and is a great app.
Highly recommended.
wow thanks iridaki for the Guide with this i will try to help Doomlord,FXP team to report about their kernel so they would come up with the perfect kernel for us
thanks again iridaki ^_^
Thanks for your kind words.
Apparently according to XDA rules, this thread belongs to General section, among threads such as "Help I am a noob" and "Is it Sunday today?" but because Doomlord (who has released a lot of V16 test kernels and needs our help to solve battery issues) as well as other kernel/ROM/app developers could benefit if us users followed this tutorial for reporting, please bookmark this thread and link to it in the development section whenever you see fit. For example when someone asks about how to check which apps drain their battery.
Thanks a lot!

We are testing new versions of Doomkernel, trying to make it as battery efficient as the stock kernel. At the moment I don't think you will get better battery time by replacing the stock kernel, but if you want to overclock your phone I can highly recommend Doomkernel.

It seems as though battery life is one of the most common topics among us vibrant owners. We are always looking to increase battery life, whether it be with a new rom, new kernels, or apps from the market. I wanted to start this thread for everyone to share their experiences, tricks of the trade, etc on getting the best battery life.
Post pictures, rom info, kernel info, app info, modem info, battery info etc! No pic, no proof!!!
This is the best I have been able to get with my phone with:
Bionix 1.3.1 - Stock kernel - KB1 modem - TW launcher - auto brightness off, set about 2 clicks from the left - battery calibration app used at 100% - Stock battery. Light / Light moderate usage, phone calls, texts, web searches. GPS on.

Well, this is great battery life you got there For me 24h is the most I can squeeze from my Vibrant with Project V/Bullet 1.42 kernel, auto brightness off, moderate usage. 16h with heavy usage... It's fully charged now so I don't have pics to show it
i used around 5% with in an hour with somewhat heavy usage this is cm7 nightly 71 bali with uv
srdjav - have you tried bali uv? I heard it works really well, especially with bi-winning, but I have heard great things about it on all different types of roms
gamikzone - impressive for cm7, I have read horror stories that the battery life on it wasn't all that great...but I guess with the kernel script and bali, it's way better!
@corpsetomb
Yes, I did tried Bali... But honestly, didn't see much difference in battery life. I have tried 4 different kernel on Project V and battery life was always 16-24h, depends of the usage. With extremely heavy usage 16h... So i decided to stay with Bullet 1.42.
But I didn't try Bi-Winning ROM yet... Maybe I will give it a try
But I had very bad experience with Super_DragonMODz 1.5 kernel... For a few hours everything was ok. But in one moment I picked up a phone after doing nothing for a half an hour and it was HOT! And I could smell "burning" inside Luckily when I took battery out and let the phone cool down, it was ok
Can we see pictures not words :/

haha what is this, a courtroom?
truly, none of this matters. one big factor in battery life is application use. in order to pinpoint someones battery usage, one would have to list, in detail, their application usage. which/how many apps poll for background data/how often? is the person using an autokiller/ram optimizer? which/how many apps stay open in the background, even when killed?
The bottom line is, battery life is ultimately determined by the user. there are only so many differences, in terms of battery, between these roms and kernels. none of them will give you a SIGNIFICANT difference. this is not the fault of the devs, they are not magicians.
This is why people do not get nice responses in rom/kernel threads when they ask "how is the battery life?". Then some clown who is a very light user will say "its great! i get 20hrs per cycle!!" and then you flash it expecting ground-shaking results...only you forgot that you have 317 apps on your phone (20 of which are constantly poll/checking for background data), and you use your phone/data like a whore who youll never see again. and unfortunately, there are horrible noobs out in there who, after doing this, will actually go back into the thread and say something like "DO NOT FLASH, MY BATTERY DOESNT EVEN LAST 8 HRS!!!!"
Theres only one true way to REALLY compare battery between ROMs/kernels (and it still isnt 100%trustworthy): download a ROM, try it out for a few days at moderate usage. Then flash the one you want to compare it to. Make sure you have the SAME exact setup as the ROM before (apps, brightness, GPS on/off, background data, etc.), and try to mimmick your usage with the other one. NOW you can effectively determine, relatively, which ROM may show better battery results for everybody. and then, when someone asks "does this have good battery?" you dont just say yes; you say "yes, i have seen noticeable improvement since coming from _______ rom, i about ___hrs more per full charge "
sorry for the rant

@TopShelf10
No worries, I welcome your input! I agree that a big factor in battery life is application use. You will see in the OP that I recommended people put in as much detail as possible along with their picture, such as what type of use, kernel, rom, etc. I would also like to hear and see comparisons between roms, that is part of what this thread is all about! To be able to compare different roms and see what helps based on usage.
Thank you for participating and your input!
Note: Do you guys think I should start a list of best battery life in the op?

You can manipulate the battery use stats pretty easily... at least on CM7. If I plug my phone in to charge for an hour, it doesn't reset my battery usage. Sometimes when I look at it it will say 24 hours+. Which I know is not at all accurate.

Happy New Year first to all.
Now what i would like to do with this thread is create a place were people can discuss about battery life and post screenshots of their battery life. Also talk about what settings you are using and what is your overall experience and what is the best screen on time you had so far.
What i like people to talk about is what kernel they use, what governor, if you are using a scheduler and if you are using any scripts to improve performance or smoothness when scrolling through screens. Also if people can provide there tricks and tips on how they get the best out of their battery might be beneficial for new users who just got their handset and looking for ways on how to get that extra juice from their battery
Over the last week i have been using Siyah kernel and i have to admit in the beginning i thought not much of the kernel. But after reading and learning regarding the Thunderbolt scripts (by Pikachu) and also that i could use the lulzactive app(by Tegrak) i was blown away by the smoothness and performance. Now if you are using scripts the app is not needed as far as i know(please someone correct me if i am wrong) but either how being able to use different apps or scripts to improve my phone even more it has left me speechless.
My average screen on time is about 4hrs and 30 minutes. That is over the duration of one day and a half. Before i used to use Savaged Zen governor and use to UnderVolt quite alot. But now after turning to Siyah kernel and trying out the lulzactive governor i am also again amazed by the battery performance.
Now different governors and different schedulers are dependent on what use you need them for. That i will not go into as there are other threads that explain all that in more detail. Please see here for more information:[REF][&Tweaks] Kernel Governors, Modules, I/O Schedulers & CPU Tweaks: Siyah & Others
My idea behind this thread is to keep in one place everything. Regarding settings, what scripts you use, what app you guys prefer either if it is Voltage Control, No Frills or SetCpu or if you recommend any other ones and what scripts are best to use if you do not like to use an app to control all your frequencies. What kernel you guys prefer and which one gives you best performance, or best battery life or even which one you guys has the best of both worlds. That is my aim for this thread..
Not to have wars in which one is best or not. Just a discussion on how people can improve or learn even on how to use scripts or how to get the most out of their battery and improve performance as well. Yes again i will say there are loads of threads but if you have one were each member can provide their experience someone might benefit from all this.
And as a pointer yes i know let's say my settings that i use might not work for someone else. But if we can give pointers and examples to others on how to start and they can use my one as a template say on how to improve their ones then why not i say.
Anyway guys i know for some they might not like this thread and for some they might say it is not worth the hassle. But if you can give ideas on how to improve the thread and please first see my idea and logic were i want to go with this then please feel free to input and give me your opinions in improving it.
Thank you to all and have a very Happy New Year.
Credits to all the devs and specially the creators of all the kernels out there who make my phone into the beast it is now. Respect to all XDA members and this is one community worth being a member off.

Can not help you then buddy. The only thing i would suggest is try and make wifi to go off when screen is off. You can set that up when you go into settings - wifi and network and then wifi settings press menu button click on advanced and there you will find sleep policy and try switching it to when screen is off for wifi to sleep come out and reboot

You do realize that generally this will use more battery than staying constantly connected to wifi.
3G uses more battery than wifi.
If you think about it, the cell tower is pretty far away compared to your router.

Steve. Why would it eat more battery? I mean screen is off but having wifi on will keep your phone awake. A thing that is not really needed and would eat more battery.

Having wifi on will not keep your phone awake
Because if you have a constant connection to your router that is 5 foot away your using less battery than it constantly polling to the data tower which is prob a few miles away.
If your out and about turn wifi off as the constant searching will decrease battery.
There is a fair bit of info on the web about this, i'm afraid i haven't the time to find it out now, have a search tho.
there one example

nice one fella thanks for the link...i always thought it was the other way round. and yeah i know i always switch it off when i am out as like you say it will eat up battery by constantly scanning to find a connection. so best to use 3g when i am outdoors
systemcrasher said:
Adding to this, poor phone reception will also drain more battery.

exactly so maybe sometimes instead of having 3g best turn it to 2G or Edge to save up bit battery...
Hey there Guys,
I have been here for quite a while,
But never really signed up, I went up the ranks from having a Galaxy Ace, to an S1 and now i got a lovely S2, I have switched from SOOO MANY different Roms its ridiculous lol ^_^... I think im addicted!
Anyway,
The purpose of this thread and i hope it kicks off, Is for us to post our stats with how much battery life , Display screen time etc etc, we are getting out of our current set ups, Which i think will be helpful for all so we can "Roughly" estimate and compare between ourselves, and to help those looking for a better alternative..

it would probably be more relevant if you post a graph without charging the phone
btw, it's an interesting thread to help choose a battery efficient rom, and to see if anybody really can get a 5 h screen on time with a single charge (like i've read around here), I only get 3,5-4 hours, I'll post my stats later

The screen time highly depends on what you're doing with the phone. If you play somewhat heavy games, you won't get the 5 hours.
But if you mostly use it for light stuff, those 5 are generally easy to get. And even 6 or 7.
So in other words, this thread is simply a big fap fest/look at my e-peen hoedown ?

Ummm Not really Mate,
And well i was in a bit of a rush when i made it...
But of course there are MANY factors that can determine the battery life,
But there is also no harm in us showing what we are getting with our current setups? Im not saying we are going to get 3 days if we play like 4 hours of a game on our phone..
But for some "General Users" this may prove quite useful?
I for one am interested in the post above, Saying that he is getting 3 days, I would love to know his setup , then i can try it out and see if it works better for me?
Thats the only aim of this thread...
So i would appreciate if you didnt use such remarks mate ^_^

Using Checkrom Revolution v4 and neak 1.3.3 kernel
With stock battery

are you kidding me, 7 h and 44 mins , I get almost 4 hours screen, only by doing moderate stuff, (browsing, a few calls, some music, I'll post graphs later when the battery discharges), I'm on cm9, but it was the same before with stock roms, think i'm going to get Checkrom a try, only to see if it can reach that kind of performance

LOL I've seen someone hit 8 hours screen on with Hyperdroid. I'd have to underclock to about 500mhz and have screen brightness on the lowest setting whilst looping a blank video to hit that lmao
Sorry. I'll leave you to fap off over battery life & show each other your e-peens in peace.

No need to say sorry ,
Its a free world and we can say what we want
So please feel free to wonder off..

I just reflased Neak with my Hyperdroid rom,

Mostly browsing the internet..xda..videos on youtube..whatsapp..email..calling..and some games
Im using a mostly black wallpaper..no widgets and brightness on around 30% with sync on all the time.

These are the results I got today. It's not the best but pretty good.
Info:
• Foxhound 3.0 (KL1)
• Siyah Kernel 2.6.7
• 2000 mAh battery
• All day connected to wifi, 15 minutes max to 3G/H+
• Activities on phone: lots of whatsapp, viber calls, Internet browsing, played a few games for a few minutes (fruit ninja for example), etc
Result as in screenshots: 6 hours of screen time and over 13 hours of standby time.
well here are my stats, not very good from what i see
-the latest build of cm9
-2:36 h of screen on but 31% still left
-about 30 mins of calls, some sms, connected to a 3g network but data on only for about 10 mins and wi fi for about 3 hours
-an hour of music
-about 20 mins of games (apparatus )
I think that I'll flash Check Rom + Neak tonight to see how it goes, tomorrow the 2000 mAh battery will arrive so the next post will be with the new battery
Nice seems like we are getting some good feedback at the moment ^_^,
If we get more and more posts,
I will make some sort of Template Guideline i guess that everyone should follow when they make their Posts...
Im tempted to get a 2000mah battery it seems like a couple of people have upgraded to that, I think i will wait for a bit more feedback from others,
Still currently testing my Hyperdroid + Neak 1.3.3 at the moment,
Will see what i get out from it..

The 2000 mAh extanded battery is very nice. It adds about 20-35% battery life. What I also like is the new back cover that comes with it. The back becomes "flush" with that hump at the bottom of the phone. Also, the phone becomes more rounded. It sits better in your hand imo.
Okay guys...!! To start with I was very upset with my battery life that it doesn't even last a day or even 4-5 hours...
I was so upset that I was feeling like taking a new phone instead of this...
I also tried to add custom ROMS ( Cyanogen Mod 10.1.2, PAC ROM, AOSP )...
but nothing worked out for me...I keep asking in the forum of XDA how to save battery life, which rom does give more battery life..
Finally, I've found my own way to increase the battery life, It says learning on its own teaches you everything...!!!
I learned finally how to increase the battery life...!!
To start with, I'll let you know how much I used and how much % battery it lasted...
On my daily usage it comes to Whatsapp+ using it 24/7...!! Facebook, downloading apps, Browsing on Google Chrome, Listening Music allot, Playing games ( smaller games like Wheres my water, Despicable me, Ninja jump, Pool, Cricket, temple run, angry birds..) Asphalt 8 really sucks in battery...If you use it for 20 minutes and play that game your battery will jump from 70 to 55%...
Even after using my battery so much, I had 13% left to use...!!! A REAL SHOCK
After doing all that My battery lasted for 9 hrs and 52 minutes...!!! I was really shock with it...!!! But it really worked out...!!!
Stamina mod showed 1day and some minutes as a standby mod...!! I'll soon post the screenshot...!!
Lets start:
It's just 10 Simple steps
you need to 1st VVVV important thing is to ROOT the phone..!!
2nd..Again important thing...!!! ( DO NOT DOWNLOAD ANY BATTERY SAVING APPS )..Examples are ( GO power, Juice Defender which sucks for me, DU Battery saver...!!! )
3rd...Keep the Stamina MOD on..!!
4th..Download Better Battery Stats...for your guidance...!!
5th Make your screen brightness to 0...( Select Adapt to light conditions )...Trust me making brightness to 0 will still help you to see anything on the mobile even in the sun..I've tried it..
6th Download Greenify for Hibernating apps....which will not eat your battery allot ( Worked for me like a charm ).
7th Download Startup manager...For stopping all the apps that start when you boot the phone..
8th Don't keep any launchers ( Next Launcher, Go Launcher, Nova launcher or any other launcher except for the Xperia Home..)
9th On the homescreen, put the apps only on 1 page...!!
10th Don't use any Live wallpaper or anything news or weather widget...!!
Trust me guys..!! You'll definitely see results as I've experienced it and I'm now really happy with my Xperia Z ( Rooted) phone..!!!
Below are the screenshots!!
Uploaded new photos...!!!!

Rather than using apps like Startup manager, it is better to de-bloat and remove system apps that is known to eat up the battery or converting them to user apps, and then greenify the **** out of them.
Also with the use of custom kernel with undervolt and init.d script support will help a lot - it makes the battery life tweaking easier!

It's the screen-on time that is most important and amount of time between battery fully charged and phone shuts down because of 0% battery, not the current percentage..

Not everything, Just what you never use but Google decides that it should be running in the background wasting battery for nothing...
Its up to the reader to decide whats Worth or not to disable then.

exactly, why shouldn't we disable/shut off certain things: There are plenty of features or apps
1. I tested but didn't like or
2. which I know better alternatives to or
3. which I never use or
4. ...
Why should we leave these things (ON) on our phones?
Thats irrational.

Keep screen brightness at zero
Only one page of apps no widgets
Sorry but I'd rather have a bit less battery than neuter my phone..... I would say that's more irrational, it's like buying a sports car and saying I'll save gas If I never drive it, or only drive it ten feet every week!

Sure you can do that
I was a bit upset regarding my battery life however I myself learnt how to save battery and it worked for me...
I was also worried about the admins or some devs who will comment that don't post something like this...etc
But it's okay as It worked for me, I am guessing it should work for everyone if they do the same thing that I did..!!
As it worked for me, I thought to let other users know about this and it might be useful for them...!!

Hello.
I'm using PA 4.4.4 Final on my Nexus 4 and I need a kernel that has good battery life (3Hrs SOT will be great).
I'm a medium user, not gaming so much, etc.
I just need the kernel to have 3 things:
1.Good battery life.
2.Gamma Control.
3.Sound Control.
Thanks!

first off, these threads are not allowed on xda, period.
secondly, theres is no such thing as a magic pill for you to take for battery life for your phones. kernels do not increase battery life. battery life is determined by how you personally use your device, how you personally set it up, which apps you use, and very much the quality of your data/phone connection. thats it. everything else plays such a minor role in battery that it doesnt matter.

Only because it's on your device, it doesn't mean it's like this on any other device I think

it is like that on every kernel, not just because its my device. again, battery life has everything to do with how you personally use your device, how you personally set it up, what you install into your device, and what apps you use. also, very much so, the signal quality that you receive plays a huge role in battery life as well. this fantasizing that you will install a magic pill(kernel) that will magically make you have amazing battery life, is just that, a fantasy. if it was true, you would have this magic pill ready for every single device. but its not real, so people waste their time constantly looking for it.
Just one link:
http://forum.xda-developers.com/nexus-4/general/kernels-battery-benchmarks-t2449982
I think this is the evidence that different kernels can affect battery life.
For example not every kernel uses mpdecision hotplug driver. For example faux kernel uses Intelliplug and this lets the cores act much different than with mpdecision.
For example when I'm on Intelliplug and drag my statusbar down, only one core goes online at 1512Mhz.
And if I'm on mpdecision and drag my statusbar down, 3 or 4(!!!) cores go online! So this affects the battery.
Even if this is a stupid example

I think this is the evidence that different kernels can affect battery life.

i use trinity kernel, which keeps all 4 cores on at all times. yet i see from 4.5-5.5h sot without ever doing anything to try to get better battery. so that info you wrote means nothing actually(as how many cores are running does not affect battery). you are just caught up in good salemanship by the developer selling you his kernel. and no mpdecision runs on any of my phones, ever.

I don't run into "good salemanship" I chose this kernel because it brings the capability to optimize the color settings and even undervolting and the most important thing is the "Eco-Mode" which completly disables 2 Cores.
So my Nexus 4 is running as a dual-core phone and as you can see on the screenshot on my first post in this thread,I get 8 hours of screen on time! So please, please don't say it doesn't matter how many cores are online.
If would enable all cores, I defenatly won't get 8 hours of screen on time.

so where is the page that shows what apps you used and at what percentage? seems like youre posting fake/artificial battery stats. othewise you would actually show your usage(which you show none). we are not children here, ok some are, but us adults know whats going on in reality, there is no fooling us.

How to hell I should fake the batterystats? and please fuc**** tell me why I should do that?
This day I almost was connected to my wifi (see screenshot) and this is the fact why my batteryusage isn't that high.
Today I was at school and because of that I wasn't connected to WiFi the hole day.
Actually I've 4h 38m SOT and 13% left.
Please don't accuse me to fake something! I forgot the screenshot of the apps-list but if you want, I can try this weekend to get the same SOT!
Best regarts mate
BTW: I'm still teenager but faking such thigs isn't brave and might brings dissapointments to some which would try this IF I WOULD FAKE WHAT I'VE NOT!!!
I'll try to get the same SOT this saturday because I'm at home the hole day and you'll see guys, nothing's faked!
