Hi all,
I use codename 2.0.0rc and franco kernel latest nightly version.
the battery drops about 49% after one night(airplane mode).
i have already set the cpu to 384 to 12xx Mhz/ ondemand mode. there is no other abnormal background services or apps. others are default valuoes.
before i use aokp b30 and same kernel/radio, the power only use about 1% one night.
but when i use the codename rom, the GPS signal is very good and the connection is very fast ( severl seconds over aokp's servel minutes, i am in mainland china)
there must be something wrong, either the combination or some of the settings.
it seems that some others have similar problem.
is there anybody can teach me how to solve that?
thanks alot!!
Same problem anyone help!

I had the same problem got sick of the battery drain so went back to 1.6.0 until they had the issue sorted. Androiduser hasn't been online since the 2.0rc so dunno what's going on atm

I observed my battery first with regular use (mainly just twitter and texting, not much gaming or data usage, ie. YouTube) and I find that the battery drains about 10%~hour, or maybe even more.
Right now I'm in Buffalo and I put the phone airplane mode so I won't get charged with receiving texts (data off means better battery right?) but even with data off, I still get crazy battery drains. my phone needed a charge at 15% and it hasn't even reached 10 hours on battery, and most of the time, my phone wasn't being used. Am I doing something wrong?
Here is my settings:
- Stock rooted Bell ROM
- Faux 013u Kernel
- OC Min/Max: 1ghz/1.8ghz
- Brightness: Auto
I can't really thing of anything else that may affect the battery a lot. :/

Unless your doing gaming, which by your post, your not...why do u feel the need to over clock? Try under clocking. Hell I under clock to 800mhz and notice NO performance decrease, other than the browser not loading pages as well.
Few suggestions;
When using a tw ROM give the power saver a go
Don't over clock. That was cool in like, the hero days lol
Try out aokp, I get the best battery life with aosp ROMs....no tw crap to bog it down
Use auto brightness
Turn vibration off
Use CPU spy to ensure your phone is sleeping properly
Well, occasionally I do play games which by my experience run much smoother with OC. I use setcpu and I used the screen off profile and make sure the CPU sits at around 700 MHz, and I'd expect that to help (which it does a bit), but it doesn't help with the overall problem.
Now with your AOSP suggestion, is it safe to flash it on a Canadian I747M? (As in, I wont be getting random ATT Device Manager registration crap, etc.) Which ROM (+ kernel) would you specifically suggest?
And with the whole gaming thing put into consideration, I'd like to keep the OC since I like smooth games, but is there a way to counterbalance that for battery? Undervolting, CPU editing, etc. All the help would be greatly appreciated.

Lte hsdpa switching may have caused the problem.
I got this problem occasionally but not once after I disabled lte since last week.

Loose the kernel...trust me on that use toonz I'm ocd 2.1 and still get 20 hrs

also what is your signal bars like before airplane mode
plus it seems like you have a rogue app.
Why is your minimum soo high? Keep it at 384 or switch to Ktoonz kernel and go down to 96mhz. You can also lower your voltages to save battery.
Well, if there is the possibility of a rogue app, the only Alps that I could think of would be LightFlow along with SMS Popup.
But is my screen usage normal? 70% is a bit much no? Or is that just me?

Install Juice Defender, it helps managing wifi and 3G/4G on/off when you don't need them, actually the most thing kills your batteries are wifi and 3g.
I usually get 2% drops from sleeping for 8hrs.
btw im using WanamliteV2 and redpill 0.9 BEST COMBO!!!!!
Hi, ill tell you a little bit about myself and then get into suggesting how you can get better battery life. Okay, i have a Note 2 flashed with WanamLite V2.0 & RedPill Kernel. The battery when i got my Note 2 on the stock rom was great. But i ventured into a custom rom for the further enhancements to my experience. So i flashed on WanamLite ROM V1.5 and the regular RedPill Kernel (Rev.0.5), With only Power saving mode on and brightness set to Auto. I would get approx 20 hours total time & 8-9 hours scree on time. Then of late i decided to try out Omega ROM V7.1 + uNEAK Kernel. = Results were the battery life and performance sucked! So within 2 hours i flashed back on the newest version of WanamLite ROM (V2.0) and this time flashed RedPill Ultimate (Rev 0.7). (This version of RedPill kernel had the ability to undervolt the phone so i decided to try it out.). I undervolted each clock speed -50mV. And than my standby time went to 27 hours with 10-12 hours screen on time. (With the same settings as above). This week i decided to give Omega ROM one more chance. So a few days ago i flashed on Omega ROM V7.2 + RedPill Kernel Ultimate Rev 0.7. This time my experience has been amazing. I get better battery life than WanamLites ROM. (And i also undervolted the phone the same way as i did previously.) So as of now my total standby time is approx 30 hours with 10-13 hours screen on time.) I also have my WiFi sleep policy set to "Never" And under location services i have all 3 options uncheckmarked, motion turned off.
Getting good battery does not only depend on the OS / Kernel, it depends on you as well. And your habits. What features you have turned on. (E.G, Wifi, Data, GPS, Bluetooth etc.). Here is what i would recommend you try out:
1. Flash WanamLite ROM (V2.0 or newer).
a) While in Aroma Installer choose NOT to install any of the Bloatware. (AllShare, Talk, Yahoo News etc.)
2. Flash RedPill Ultimate Kernel (Rev 0.7 or newer).
3. Install SetCPU. Set governor to Pegasusq, and IO Scheduler to Deadline. (I get the best battery life with this combination).
4. Undervolt the CPU Clock-speed's by -50mV.
5. Turn Power Saving Mode ON - In settings.
6. Turn OFF Motion based features.
7. Set WiFi sleep policy to Never.
8. In settings under Location Services. Uncheckmark all 3 options.
9. Turn LTE OFF (If your phone has LTE).
10. And if your using a WiFi network, turn Mobile Data OFF. And vice-versa.
11. If using Bluetooth, turn it OFF when your immediately done. Same goes for GPS.
12. Leave brightness set to Auto OR under 30%-40%.
13. Invest in Titanium Backup, and use it to freeze or uninstall bloatware or junk software you DONT need! Also use it to regularly backup your apps, in case you need to flash another rom in one touch you can restore all your apps!
Try my above suggestions, and if you are still getting horrible or bad battery life than there most likely is a defect in your battery! With doing the above, you should at MINIMUM get 1 day out of your battery! (With doing the above, i can get upto 3 days!!! With medium usage! And atleast 2 days with heavy usage!)
My $0.02 cents, hope my suggestions will help you!

Hi, I would say go with WanamLite as no 2 Android phones are the same, and you are currently on Omega ROM and experiencing bad battery life and performance. I have power saving on all the time. I have never had any issues with lag! With power saving mode on i get a benchmark of 5800, with it turned off i get a benchmark of 6700. So just from that you can gather i have no performance related issues with power saving mode on. Also dont forget to flash RedPill ULTIMATE! A good kernel makes a HUGEEEEEE difference in performance and battery life! I have tried a few different kernels, so i can safely say that RedPill Ultimate is the only kernel that gave me the best battery life ALONG with amazing performance WITHOUT ANY COMPROMISES!! And media using up 62% of your battery that is something that is not right! Try removing the Music Player Widget from your homescreen and see if this persists. But once you flash another rom this issue should automatically be resolved.

Oh and dont forget to Wipe Data / Factory Reset AND Go into Mounts and Format /System!!!!! - When flashing WanamLite or any other ROM.

tbh i think Omega has gave me a little better battery life then Wanam because when i was on wanam today morning it dropped from 100 to 20 even when the phone was on airplane mode and the screen was off all the time!

Try the suggestions i gave you in my first post, including the flashing of WanamLite & RedPill. Follow all my instructions and use it for a day. Tell me tomorrow how things fare out,
I dont everything you told me to do except the power save i unchecked screen power saving that made my phone lag and ive been drawing on the s note and its been in 57 for a couple of minutes..i think why my phone keeps draining battery when my screen is off is because of deep sleep..it drained 80 % when i was on stock kernel i hope that doesnt happen with red pill i flashed the ultimate 0.7.
Thanks alot man again ill give you my results tomorrow!

i dont understand, so you DID everything i told you to do including flashing WanamLite? Also in deep sleep the phone uses less power ... also i forgot to mention. Go into Settings - SPen, and turn on the battery saving feature. It REALLY helps. What it does is, when the S-Pen is docked inside the phone, it turns OFF the Wacom digitizer thats embedded into the phones regular digitizer saving you battery! I noticed a significant boost in battery life when i first turned that feature on.
Yup did everything including flashing Red pill and Wanam rom (i already had it in my pc ! ) but im using CPU spy and my phone isnt going to deep sleep im pretty sure my battery drain when in standby is from it not going to Deep sleep

Not really. Im a heavy user and my screen is almost always on. And my battery life is amazing. Did you also undervolt the phone using SetCPU and change the governors to what i suggested?

Yeah i undervolted each one of them to -50 using setCPU it definitley bumped up my battery life but ..i really need the phone to go to deep sleep cause i just left the phone for about 3 minutes and dropped 3 %..should i update to the Stable version of 0.9 or stay with 0.7 ultimate?

There are 2 versions of RedPill, Stable, Ultimate. I was using stable for the longest time. And recently started using Ultimate. Ultimate gives you the features to undervolt. And i would recommend you stop flashing rom after rom and same with kernel, You have to give the ROM and Kernel some time to set in. Now that you have followed my instructions i would suggest you just use the device normally without worrying about battery life for atleast a couple of days. Hopefully by then everything should improve and settle in. The whole issue of deep sleep, as far as I know the phone has to be sitting idle for quite some time before it goes into a deep sleep. I could be wrong. The moment you turn off the screen the phone does not / is not supposed to go into deep sleep! Also one more thing you can do, which i also forgot to mention: Go into SetCPU, slide to the right to get into the "Profiles" page. And make a new profile, so that when you turn off your screen, the Minmum CPU speed is 200 Mhz, and the Maximum CPU speed is 400 Mhz. That will also boost the battery because it will limit the processor to down-throttle while the screen if off! Remember, dont jump the gun and flash anything else. Let everything settle down and than let me know tomorrow if you see any improvements!
---------- Post added at 03:41 PM ---------- Previous post was at 03:39 PM ----------
Oh and one more thing, since I believe this is the third ROM you have flashed today or at least the second. Boot Into ClockworkMod Recovery and goto advanced, and wipe your battery status!
Batterylife issues?
Well... I'm running Jellybam (CM10/PA/AOKP) and I can use mobile data, Wlan, GPS, gaming, listening music and phone about 11 hours while surfing in the web and stuff and I'm going down to kinda 10% in that time. Oh, I got the N.E.A.K. kernel flashed.

I havnt tried that ROM, but i have certainly tried that Kernel, and i didnt have any good luck with it. Based on your usage i think maybe you would benefit from trying out WanamLite ROM + RedPill kernel. You will most certainly get close to 18-24 hours standby time and more than double your screen on time. Try it out!
Install BetteryBatteyStats and then check Kernel Wakelocks and Partial Wakelocks.
Should help you narrow down what is causing your phone not to go into deep sleep. Probably some rogue app.
As citizenlee said, install better battery stats. From what you've said it definitely sounds like a wakelock issue because I have wifi, data and gps always on with stock rom and kernel and my phone gets me through the day easily. Normally about 17 hours total time with screen on about 5-6 hours.
I also have autosync on with everything as push.
Can you post a screenshot of your battery usage including the main usave page and the detailed one that you get when you click on the graph

Perhaps with airplane mode on (wifi, bluetooth, nfc, data, gps etc all disabled) and screen brightness all the way down, it could be possible to get that 13hrs if you are just reading a book?
But with realistic everyday use does seem farfetched lol
