Hi
I'm a regular flasher and am using Phoenix V12 as my daily rom because of its smoothness and battery life.
Now, Ive tried multiple 4.3 ROMS (DN3, Dr Ketans V1,V2,V3,Phoenix V14 & V15)
Whats consistent and worrying in all of them is that while they work mighty fine, my battery lifes taken a hit.
Its down to 3.5 hours screen on on all ROMS from 6.5 hrs screen on in 4.1.2.
Ive tried installing, reinstalling, wiping data, dalvik, battery calibration, full 3-4 charging cycles and all possible permutations and combinations of the same but to no avail.
I really want to migrate to 4.3 so how can I resolve my battery problem?
Thanks!
Turn off services/apps you dont need.
Perhaps you would take a look over,
Settings->wifi->advanced-> Scanning always available.
Untick this options. This would kills your battery quickly as many users faced it before.
Also can refer the method that provided by TheATHEiST, close some apps/service that you wont longer require on 4.3 anymore.
AutoStart Check i would recommend to you. Doing well for me.
:good:

I've installed Dr. Ketans V5 MK4 ROM and the battery is just as outstanding as it was on 4.1.2 Stock ROM.
The only thing I noticed is that WiFi is now draining battery a little faster than on the stock ROM. Might have something to do with the WiFi patch I've applied because on couple of custom ROM's I 've installed, the WiFi was not working right after flashing.
You also might try some battery saving apps. I am quite sattisfied with Juice Defender, but those apps are only doing their job while the device is in sleep mode by killing the wake locks. When you are using the phone, ther is no app in the world that will help you save the juice.
Battery Drain
I am using PA 3.99 on my Note 2. Previously when I was on stock, I used to get 2 days from a complete charge with standard usage of WiFi and Data. Now, I can barely get 1 day from a full charge.:crying:
There are no background apps running, "Scanning always Available" is off in WiFi settings. GPS off. Sync off. Location Services off.

Hi, have you considered the possibility that your battery has also aged? I assume that it is 1yr or so already so your previous time of 6.5 is no longer possible tho, 3.5 hrs screen on is low on my >1yr old battery, i use to have 4.5 hrs on DN3 V3. Hope i gave you another perspective.
Cheers

Hi! Before i have got a drain of 3-6 mA with most of the roms, but suddenly all roms dain 16-20 mA. No matter if it is MIUI , cm7 or sense roms. They all have the same drain .. is my battery bad ?
Got my phone waterdamaged 2 weeks ago , but this bad battery time started yesterday...
First you need to calibrate the battery.
Charge your phone until Current Widget shows 0mA. Then go into recovery and delete battery stats. Let the phone discharge until it shuts down by itself, then charge until it is back to 0mA. That will calibrate the battery.
Secondly, new ROM's do take a few days to "learn" how to use the battery most efficiently so you wont get the best battery life instantly.

I know that ROM´s need a few days , but i have waited a few days ,and noticed that it is allways the same drain... But i will try calibrate my battery next
And please make sure that during the period of charging it the second time that you do not take it off the charger. That will mess up the calibration and you will have to start all over again.
you might want to try a new radio too
same for me. I tried everything I could.
I tried these roms:
-coredroid
-ARHD
-honey
-virtuous
-MIUI(current)
I tried these methods:
-multiple new recommended radio + ril
-battery calibration app + clear battery stats(recovery) @ 100%.
-full wipe 1.5
-re-root(hack kit v12.3)
-different kernels
When I first rooted my phone battery was perfect on any roms until I flashed ARHD,thats when my battery drainage happened.

how many hours you are getting now....with regular usage ????
I'm getting the same here... Started with ARDH too, then LeeDroid, now Virtuous.
Clean installs each time, apps restored using Titanium. Also re-flashed the recommended Radios too and calibrated the battery once.
Current drain is 15% / hour on Standby ~70+mA.
I noticed no unusal Wake Locks either.
I'm loving Virtuous, but thinking to go back to stock if the new Viruous update doesn't solve this.
Just whilst typing this I lost 2% :-(
Yeah this is no fun...

Delete all htc account and calibrate the battery
Hey, I'm trying to fix my battery drain during light use. Having screen on for not even 5 minutes eats around 2% of my battery. I've calibrated, gone through many different ROMs [GB(CM7,MIUI,Sense) and ICS] with full wipes(format and wipe). leading to my question in hand... how do I completely wipe my phone? I visit the wifi settings and see a wifi history that were from a pretty long time ago(before wipes). This leaves me thinking I have not fully wiped my phone in between flashing. Does the google account save wifi history or something? Thanks for any tips!
My problem still persists any help is appreciated

You seem to be wiping your phone correctly. The WiFi settings are backed up under the Google account and are restored when you add the account again. It also backs up other settings, wallpaper, and app data of certain apps. Here's an easy way to fully wipe your phone (including the SD card app files in .android_secure) - http://tinyurl.com/66fc8og
It's called super wipe script and it is from the Android Revolution HD ROM thread, thanks to mike1986.
Sometimes the battery loses it's ability to hold charge after sometime. This happens when the battery is quite old or due to various reasons that I don't know. You'll need to get a new battery then.
On the ROM side, a good ROM+kernel combo gives the best battery life. Instead of using a plethora of apps to save battery, finding the right ROM & kernel combo and choosing a good CPU governor and min-max frequency settings will give you much less battery drain. I don't use any battery saving apps, but I run a great ROM (CM7.2 RC1) with an awesome kernel (LorDModUE 8.9b7), with smartassv2 governor running 122-1152 Mhz and a few build.prop tweaks.
You can try out my combo and see if you're getting any better battery life. The max I've gotten recently is 14 hours of heavy use with 4 hours of screen on time, wifi on for 75% of the time and a lot of web browsing and video watching. I usually keep my phone in 2G mode and only change to 3G when I need to use the internet. 3G drains the battery really fast. On average I get around 13 hours heavy use, 1 day medium use and more than a day of light use (with mobile data off unless when necessary). I get around 1% per hour drain in standby.
You can try this ROM VictoryMod by victoryo. It has my same ROM+kernel combo I've mentioned before + build.prop tweaks. Change the CPU governor to smartassv2 with 122-1152 Mhz frequency. It gives great battery life.
Among the Sense ROMs, Android Revolution HD with klquicksall's kernel and LeeDrOiD HD with LeeDrOiD's kernel give awesome battery life.
Thanks for the reply! I greatly appreciate it. As for my ROM, I've been using the latest LeeDroid, but the battery drain seems to be happening across all the ROMs I've tried recently. I never install battery saving apps, and I keep default kernels and settings. The problem is probably with my battery, I've had this phone since last May, so almost a year. I'll see if I can get this problem sorted out. Thanks again!
I have recently installed cyanogenmod 10.1 onto my galaxy s3. The battery life since then has been very poor. If I leave my phone on without even using it, it drains about 1% every couple of minutes. When I look at the battery it says that the process of "phone" is taking up a huge amount of battery. Can anyone tell me why this is or how I can fix it?

Generally these issues are user related and not ROM related.
I was so frustrated with some of the ROMs when I first started out but then realized I was doing a few things wrong (mainly because these ROMs, including CM10 have very decent battery life).
First, I would recommend a clean reflash:
factory wipe / reset
wipe cache (some say twice)
wipe dalvik cache
install ROM
after rom loads, wait 5 minutes (don't touch at all) then reboot
now you must wait.. sometimes it takes 24 hrs or so for a ROM to correctly load.
Not sure how true it is, but some say to now drain battery down, then fully charge.
At any rate, I follow these steps all the time and works great!
Also, keep in mind that most of battery issues are user related.. so think about what settings, apps and kernels are being used on your end before question a ROM. This is why waiting 24 hours or so before installing all of our "crap" will give give the ROM more time to settle.
Hope this help!!!! Happy Flashing
Thanks for the reply. However, I have looked at what apps and processes are draining my battery. And it appears it is the "phone" process that is doing this.

Just to piggyback on spenny88's reply, exactly what did you come from (stock?) and how did you wipe and flash?
This is all key as to how well your device will perform.

I have noticed something similar. I am coming from stock. I am going to guess my battery life is in the neighborhood of 10% less. I wiped everything before I installed CM. That said, this feels so much faster than stock.

Having the same issue with my Samsung Galaxy Tab P1000 (p1 in Cyanogenmod). "Cell Standby" is taking as much juice as "Screen", and I am using Wifi only. I don't even have a sim card in the device. Wish there was a way to disable Mobile Networks without disabling Wifi via Airplane Mode.
I installed through Rom Manager as upgrade from CyanogenMod 9.1 with wipe. I will try the recommendations above and report back.
Try the latest nightly (or RC4) of CM10.1. The battery life has definitely improved a bit.
Samsung Galaxy s3 intl battery drain cm10.1
I recently installed cm10.1 nightly on my international S3, it has cut the battery life down drastically and seems to drain over 10% an hour, even when not being used.
I've tried everything that i've came across by searching and still haven't had any real gain on battery life. Doing a full wipe and reinstalling doesn't help, and i've given it time for battery to calibrate; no difference. Even with wi-fi and location services off i'm getting a big drain. I've even tried switching to Slim Bean, if anything the battery was worse still.
Firstly i'm getting that Android OS is eating up a large chunk (usually above 60%) and using BetteryBatteryStats i don't see anything out of the ordinary in terms of partial and/or kernel wakelocks. I really don't wanna have to put the stock Touchwiz rom back on but that seems like the ways it's going. Any help would be greatly appreciated. Is there anything else i can try?
i find i get terrrible battery life on AOSP when i restore google through the setup. i skip thru the installation and open the play store to enter my gmail. then, before restoring my apps, i let it charge to 100%. honestly AOSP still doesnt have decent battery life, but it does improve if you play with it and try different things

I would respectfully disagree with you. I have run a number of ASOP based ROMs and find them better than stock in terms of battery life. Certainly better in terms of not making my eye bleed (as I hate touchwiz, but that is a personal preference). I find that SlimBean gets me the best battery life of the CM based ROMs.
To clarify, I get just over 1%/hour battery drain, when idle (as measured by BBS) with GPS and google sync enabled, mostly on LTE. My phone happily spends almost all the time I am not actively using it in deep sleep.
The recipe to achieve this is to disable google location reporting and history, avoid tons of widgets that constantly update themselves, disable samsung services that you do not use, and monitor battery usage to look out for rogue apps that do stupid thengs, like hold wakelocks when they should be idle. Dropping the minimum frequency to 192 MHz, and going to ASSWAX (CPU scheduler) and ROW (I/O scheduler) also helps.
To get decent performance you do need to install things properly. Which means ensuring that you don't have conflicting settings or random leftovers. I tend to dirty flash updates but you reallly do get better and more consistent performance going through the pain of a complete clean install (format system, clear cache, reload apps from the store) when you are switching ROMs. Only use TiBu to restore app data. Once you do this, in my experience rogue wakelocks are the biggest cause of lousy bettery perfromance, and you can track down and eliminate these. I have around 150 apps loaded and do not run any task manager/autokiller. My phone typically runs without any reboots or power cycles between ROM updates which equates to rebooting every couple of weeks to a month. I have seen over 2 months of uptime.
Certainly should be able to go 16-20 hours between charges which I would consider real world all day functionality. I guess my point is that rock solid stability and all day battery life is possible if you are systematic about how you do things.

Hi,
I follow the forums here for years but have not posted yet, hence not allowed to post on the dev forum in the appropriate thread, had to open a new one
A couple of days ago I installed "[ROM][JB][4.3.1][JLS36I] CyanogenMod 10.2 Alpha (Build 3)" on my wife's phone. Until then she was still using the stock GingerBread ROM. The phone got so slow to the point of not being usable at all.
After I flashed to CM 10.2 it feels like a new phone. Lightning fast, good looks, everything works - fantastic, very much appreciated and thank you very much @ Devs!!! :good::good::good:
One big problem though:
When running the stock ROM the battery usually lasted about 2 days. Now, with CM10.2 it is empty after half a day. Since I did a full wipe before she is using less Apps as compared to before and there is no single big consumer. Just the typical mail apps, facebook etc.
When I look at the wakelocks there is one app consuming most CPU which is CSipSimple. But that app was also running before the upgrade when the battery lasted 2 days.
The screen seems to consume more power though, is that possible? Anyone else with similar experiences?
Thank you very much!

You can try out battery calibration app before new kernel. Cause there is no "wipe battery stats" on cwm 6.0.4.4. I had same problem, and its a bit effected on cm 10.2. It's free. Maybe it will solve your problem.
Battery Calibration
That sounds very good, let me try that!
I have the same issue with increased battery drain. Yet I've not been able to identify the source. I disabled a lot of services (with Disable Service), also deactivated unnecessary system apps.
Cell standby is also shown as a huge drainer, although I usually have a good signal and no losses (checked with Better Battery Stats). There are no wake locks out of the ordinary.
Now I'll try battery calibration to see if that helps at least some amount.
Actually for me nothing really helped.
I eventually identified the 3 apps that drained the battery via Wakelock detector.
Those apps are Facebook, GMX Mail (based on K9 mailer) and CSipCimple.
Before the update to 4.3 my wifes phone was running the stock gingerbread and did not have an issue at all with those apps.
Yet on CM4.3 they are draining the battery.
Once I uninstalled the apps the batter life is back to normal. Which is sad, because she needs those apps. But no other solution so far from my side....

Again the myth with whiping battery stats / battery calibration. Make a full charge and unplug the charger. This will whipe your battery stats.
And for the ones who never get this. The stats are just some data about apps consumption collected while the battery gets discharged. The ROMs are whiping them by itself on each full charge and after shuting down the phone.
This data has no Infulence to how long a battery lasts. It´s just collected to show you visually the statistics.

At least I thought it helps with the effect that the first 50% of the battery last 3 times as long as the last 50%, but not even that changed

I had the same problem with my S4 running CM 10.2 stable. The battery was empty after 8 hours. What I did was to change the theme, and today i got 12 hours and only 20% of the battery gone and wi-fi/3g all the time. Well, I still have only one hour of screen up time, but that is how it was before... I don't know, i'm just saying! Maybe it helps. The theme i added is LunarUi 2.
All the best!
Hi Guys,
i have a bit of a problem with the battery in my GNex maguro.
I'm an avid Rom flasher, but when i have something that works well i usually settle with it for a while. So i flashed Cataclysm (http://forum.xda-developers.com/showthread.php?t=1995801) sometime in the last months and it was running great. Best bettery life i had so far.
Then with the release of Android 4.4 i looked for a rom to test it. I flashed XP (http://forum.xda-developers.com/showthread.php?t=2539201) and i really like the 4.4 changes.
But since then my battery won't even last a day in standby mode. I thought maybe it's an issue with 4.4. still, but even after flashing back to Cataclysm (newest release) i still had the same issues. I thought it may well be, that the final version isn't what it used to be, so i flashed another rom again. This time Purity (http://forum.xda-developers.com/showthread.php?t=2012706) aaaand... still the same problem. So now i'm pretty much lost. I also tried different kernels (lean kernel specifically) but to no avail.
My battery used to last 2+ days in idle mode. Now i can see my battery drop every minute. It barely holds over 10 hours. I already did a full phone wipe and flashed back to stock before installing cataclysm again but still no improvement.
I hope someone can help me here or point in the right direction.
Sorry if this topic already exists, but the search funtion doesn't seem to work right now and google didn't show something helpfull.
Thank you all in advance.
I don't know why you would still have bad battery life moving back to the original rom you used but.. on 4.4 it is most likely the new Google Now features that constantly listen for voice commands. Disable it by long pressing on an empty part of the home screen and go to settings. Slide Google Now Off and go to voice and turn off hotword detection as well.
I get great standby battery life on 4.4. I'm running the 11/29 ART build of cmetal(toro), 150ish hours of uptime without any issues so far.
Re: Bad Battery Life since KK
What kernel are you running? Are you just using whatever kernels come with each ROM?
I'll try turning off google now and the voice stuff and report back.
It still seems really weird to me, that the problem still persists after flashing back to 4.3. My guess would be, that 4.4 flashes something hidden that messes with the battery. But i don't know where or what.
Especially since it persists after a complete wipe (/data, /system and /cache).
Well, i'll see how it behaves without google now.

Well i used mostly lean Kernel with 4.3 roms but i can't find any 4.4 kerneles besides CM. I have XP installed right know which uses CM Kernel.
Re:Bad Battery
Make sure your governor is set to interactive or ondemand...it could be seeing power drain from being set to one of the performance settings.
It's also possible that your battery is just going bad...do you have a backup battery you can try?

It could just be that you need to replace your battery. They are only good for so many charges and do degrade.

Reporting back. After deactivating google now yesterday my battery is still ****. It's at 50% after 2h idle and 30 minutes screentime. Before the 4.4 flash it would be at around ~85-90% now. I suspect that 4.4 flashes something in some hidden partition that i don't have access to, that messes with the battery. Users on other boards report the same issues as i have.

Could be, of course. But it's kinda weird that the decline is so dramatic and it has to be a pretty big coincidence that it just happend after a 4.4 flash. Seems unlikely to me.
edit: I'll order a new battery just to eliminate the battery as the source of error.
Mine is pretty bad but it's running google play to death so maybe gapps flash was bad? dunno

Same problem here. Since I flashed Kitkat on my phone, battery life isn't enough to last a day on standby. I tried installing another kernel (ASKP) but to no avail. Please keep in mind that I'm not very experienced with custom roms and rooting my phone. Does anyone have some good tips to improve battery life?
Update: After fiddling around a bit with better battery stats, greenify and a bunch of other stuff... i still don't have a solution. I made some screenshots of my stats, but can't post them here because i don't have permission to do that...
So i reflashed swordrune's cm11 rom and it seems to be working better with 1080p kernel w/o art enabled. i'm 11 hrs in with 80% battery on the extended battery (toro btw)

are u sure greenify didnt helping??? already got rooted & exposed installer running??
can u state your screen on time??
usually gnex can handle 3-4 hour screen on depend on battery condition n phone performance... not include idle n stanby time.

Not to hijack your thread, but I'm also experiencing battery issues after flashing the XP 4.4 rom. I did enjoy it but the battery drain was terrible. Not only that, for some reason my charger drains on a 1A charger but charges slowly on a .7A somehow. I only have 1 micro usb cable so I can't test if it's the cable and I can't find any apps to check the current speed. I tried downgrading and flashing to Slimbean but so far it's been no dice.

Ok, back again. hibernated every app and system-app that was running in background. Still wasn't getting better. I then saw the only services still running are google location services. I deactivated them now to see if these are causing it.
The biggest wakelocks i have are "wlan_rx_wake" which seem to be a known problem with KK:

I then researched again and found several threads in google groups which describe the same problems that i have. Across several devices (though mostly Nexus 4, 5 and 7).
Google seems to be aware of that issue and is working on it.

Yes, same for me. Charging is really slow since 4.4 as is the bootprocess of my phone. From the first vibrate when switching the phone on it takes ~10 seconds until the google logo pops up.
i dont know any about gapps issues bcoz not running any gapps in my phone since last year.
1. try searching for updated radio.img (baseband/ radio) if got any network issue.
2. try install trickster mod app. this app can help you for tweaking into deep sleep, also help for optimizing.

Hmm I don't know if this is going to resolve the charging problem but i will try it and also try and use a battery calibrater and come back.
