I have upgraded my Galaxy W to Jelly Bean using Custom Room (4.2.2) Cyanogenmod 10.1 alpha 2. maybe later alpha 3.
Everything runs well. but why my phone's battery drains so fast? and please help me HOW TO SOLVE IT AND MAKE IT LAST LONG TIME???
THANKS VERY MUCH....
Backup your apps, factory reset your phone. If battery drain problem persists, install Greenify or deep Sleep battery saver from Google Play to better manage battery resources.

when you just flashed the battery will definitely be shorter. Let it recharge for a few cycles before determining whether its good or bad battery life. Keep in mind however that even at full potential, the battery will not last for more than 2 days even at light usage.
if battery life is more important to you compared to "the newest OS" and whatever extra features it brings with it, then I highly recommend installing acro's CM9 RC2 (yes it is ICS) as the 2.x.x kernel is far better at battery life than 3.x.x (i'm currently testing it and I can already feel the difference! I believe I can reach 2.5 days at modest usage but I will have to update you on that after my first few discharge cycle for battery to reach potential after flashing new rom). I do, however notice a few annoyances with RC2 (not sure if its really the ROM, or the custom kernel i'm using, or Nova Launcher is to be blamed), so if it continues to bug me I may just switch back out to latest ICS =p.
If keeping with the latest JB is important for u, best thing you could do is download a custom kernel for it that supports UV(undervolting), then get IncrediControl and tune down your UV based on some voltage tables you can find in FAQ. This alone won't bring you a HUGE improvement in battery life but its definitely an observable difference. On top of UV, try to UC(underclock) your CPU to 1GHz. Most daily functions, apps and games (depending on how intensive it is) will work perfectly smooth even at 1GHz. IMO, the most important point of UCing is you will notice a very significant difference in the heat of your battery (ie backcover of your phone). Heat is generally bad for the battery (shorter life + faster draining) so UC is definitely a good thing to do =). Of course, on top of all those, get greenify and wakelock detector(WLD) from market to control your not-so-frequently-used apps. Use WLD to track down what is keeping your phone awake (hence drain more battery) and use greenify to hibernate all the not-so-frequently-used apps you have (example of things you DON'T want to greenify: whatsapp and gmail as you don't want to kill these 2 programs when you lock your screen. You want to continue receiving whatsapp messages and gmail when you locked your screen right? XD! Examples of things you SHOULD greenify: games, music player. Maybe some of the games or other apps may keep a background service active, secretly using your battery even though the last time you used it was 2 days ago!)
Finally, if your wonder is about 1-1.5 years old, chances are your battery is already bloated (perhaps you can feel your battery through the backcover of your phone even!) A bloated battery is a dangerous and short-capacity battery. Even with the best rom you may only push through a day from 100-0%. If your battery still looks fine but your phone is nearing its birthday, go ahead and do some online shopping (ebay or local equivalent, like malaysia we have Lelong.com.my) and get a battery for your phone. Its usually much cheaper than buying from telephone shops.
EDIT: Adding on to all of that, choosing a good governor+i/o scheduler combo is important as well. If our phone is similar with the S+, smartassv2+sio(i've used this, its quite smooth and battery is good) OR OnDemand+noop is thought to be very good in terms of battery life and responsiveness. Lulzactive is also very good but its not so easy to tune it so i usually would stay away from it. Do bear in mind that although the former 2 combo is good, it still highly depends on how you use your phone so there will not be a universally best governor+io combo. Both of those suggested by me are supposingly best in responsiveness as well as deepsleep battery conserving (only if the assumption that our roms work the same as the roms tested in S+, which MAY NOT be true).
TL;DR? try smartassv2+sio (u may change this using IncrediControl, get from playstore). Then if you are not satisfied with your current performance/battery life, you may continue experimenting by changing governor and i/o scheduler one at a time. If you are doing the testing, make sure to have some way to record your tests if not you will 100% be deceived by placebo!(with actual numbers you will clearly see whether your feeling is placebo or if there really is an improvement)
I'm having some seeeeerious battery issues with alpha3. With just 15 minutes screen usage in a day, battery settings says my screen used up more than 20% of the battery! This just for consulting the time and the weather.

Sounds like your battery is bloated. Can u show me a screenshot of your battery graph and app usage?

that 20% is not actually the 20% of the battery juice. It is 20% of whatever amount of battery is drained due to the display being ON. Like if your battery is used from 100% to 90%, then only 2% is used by the display.
I am not sure if I could explain what I mean.
EDIT: Hmmm maybe I misunderstood what you said... If that is the case, disregard.
And also my galaxy W will use all of its battery charge when the display is constantly ON for about 3-5 hours.
Actually, I've figured out what it was. It was Google Now. Chewing away at the battery without saying a word anywhere in the battery screen. I am now back to my old 3 days battery.
you need to install cpu spay from google play and you need look deep sleep time.
this reaction is typical if your coming from a stock or at least cm9.
there has been a lot of arguments about battery life of cm10 and above.
in my opinion, there really is a difference, i mean cm10+ drains battery faster.
and the reason being is of course the features there is in cm10++.
if you're after battery life, stay with stock or cm9 (for now).
but if you feel like your in with cm10+ and you don't want to go back like me, then may want to try these tricks:
1) using Titanium Backup, freeze the apps that you don't really use.
- in my phone i froze pico tts, voice search, talk back, etc. (i even froze google search )
2) i use an app called "autostarts", it can disable auto starting of app including those of the system.
- in my phone, i disabled google maps in every activity. ex. after startup, connectivity changed, wifi connected, widget updating
3) disable system settings which also contribute to battery draining.
- disable location service when your not using it
- disable automatic backup/restore
- disable haptic feedback
- disable autosync
- disable the top battery drainers when not in use (wifi, mobile data, gps, bluetooth)
- and many more just explore
4) do not use so many widgets (my home screen has 0 widget)
5) do not use live wallpaper
6) charge only using the original charger, not from other phone/brand, not from a usb port
- the best way to charge is to avoid using the phone until it's fully charged
7) finally, install only apps that you really need. just keep a backup of your not so often used apps and install only when you need them
If you think about it, everything i wrote above contradicts with the original concept of Android.
But that's life, sometimes you have to trade something in order to achieve another.
Our phone was baked as Gingerbread, now we want to make it taste like Jellybean.
We have all the ingredients, but we don't have a jelly bean pan to make the candy molds.
So we improvise, we work around, we do some shortcuts, we make alternatives, certainly it will cost something.

Hey guys
I recently installed CM12 (official version) but i noticed that it eats up alot of battery alot quicker than my stock ROM
i installed better battery stats and started recording stuff but idk how to read the information it provides
can someone help me?
Thanks
You could also try a cpu app such as no frills cpu to set the min and max frequencies.
I don't want to mess with clocks till I have expended all my other options. Do you guys know how to use the information betterbattery stats record?

Set BBS to show stats since Unplugged.
Charge your device so that it is fully charged just before going to bed.
Unplug and let it set idle overnight. This will let you know about background processes consuming battery, as opposed to you actually using the phone and consuming battery.
First thing in the morning open BBS. Click the share icon at the top left of the screen. Select the Text Dumpfile option and then Save. You could then take screenshots of the BBS pages; especially Partial Wakelocks, Other, and Alarms.
There are active threads with participants who are very familiar with interpreting the BBS results obtained.

The kernel that comes with CM13 works reasonably well. A few things can cause excessive battery drain and its not just the kernel that is at fault. We don't know all the settings and installed apps of the people who have claimed long battery life for their phones after flashing this rom or that kernel, or even if their testing methods are reliable and can be compared with others. So any claims about long battery life is very suspect.
Google services has always had a big problem with power drain because of bugs. Google's location data gathering is not only bad for privacy but for draining power as well. And many free apps tend to use too many non-related permissions and they may misuse google play services which also drains power. So the easiest thing is install the bare minimum of google apps (start with google pico package) and use xprivacy to tighten up permissions. I think nothing can be can be done with rogue apps that use google play services.

What do you use your phone for if you don't install google play and gapps? Many people including some reputable posters liked Kairi's Xcelerate for increasing battery life but there isn't a version yet for MM. You could try the God's kernel which works with CM13 but it looks buggy from the looks of things.
I doubt any kernel (Xcelerate included) can instantly transform the redmi 1s and give it good battery life. 4-5 hours of SOT is reasonably good and believable. Claims of 12-16 hours otoh......

Whats up people I want some information how I can fix this massive battary drain on my H815. I have root and unlocked bootloader, what can I do?
Flash for example imperium rom. It's stock based with many improvements.
Why do ypu have that huge battery drain? Use GSam Battwry monitor to find out what causes it.
Some tips to make your phone last longer:
- Lower the brightness
- Turn off GPS, NFC, and Sync
- Use Greenify to freeze apps (Facebook and Messenger is a really big battery drainer!)
- Use a debloated system, or debloat yourself what you dont need
- Use the GlassFish 1.2 EX Kernel profile, with battery friendly settings
- Dont charge your phone to 100%, for ex. dont leave it at charger a full night long, cause Li-Ion needs to be cycled

There may be apps running in the background. Find out about them. See which app is consuming max battery. If possible, clean flash a ROM like bootleggers and flash bfr kernel under clocked. The download link is available in the bootleggers thread.

Kindly share few basic information with your question.
Which ROM
Which baseband
Which kerñel
How many sim card
Which is your primary network
Your usage patterns (games or social or video, or like 4G or WiFi)
Age of Phone (actually age of your battery)
What is your SOT and standby (how often do you need to charge?)
Etc..
Usually battery monitoring apps like AccuBattery can give you good idea on what is using how much battery !!
