I need some advice on how to tune for better battery life when using the UnOriginal ROM v1.4.6.
I ran UnNamed for some time before switching over to this ROM and never had any battery issues so I am a little in the dark as to how to go about finding out what is killing my battery. I love the ROM and have no intention of switching.
Battery life is roughly 8-9 hours in normal use. With everything shut down battery life is off the charts. 6 hours unplugged and at 95% so far today.
I suspect sync, but I rely on Google calendar and Gmail so I don't wish to go without.
I spent many hours yesterday reading posts without finding anything so a point in the right direction would be appreciated.

There are lots of things you can do to diagnose and resolve battery issues.
(I don't know what your current setup is other than ROM)
1. Get the free app Better Battery Stats.
2. Get free app CPU spy.
3. Check the thread for known battery drainers.
4. Use setCPU w/ profiles.
5. Check your kernel threads, some versions have better battery usage then others.
6. Look into init.d scripts such as init.doh
If the problem is high Android OS usage with lots of wlan_rx_wake wakelocks - sorry, you need to switch off of the horribly broken UCKK6 base to fix it.
One thing that's helped me is Tasker. I use it to turn off data when the screen is off and turn data on when the screen is on. I also use SetCPU to undervolt a little, and set my max CPU speed to 1000mhz.

Something that helps is turning off Data Backup, which is in Settings > Privacy. You should also try to disable as much syncing as possible, as that will prevent the CPU from entering deep sleep.
SetCPU lets you set profiles, like when the screen is off set the CPU speed to 200mhz-500mhz. You can undervolt the CPU and underclock it for even more power saving. I have mine at 200-800mhz and it's still very fast.
I never knew the UCKK6 was horribly broken? It has always provided me excellent reception and call quality. Much better than anything else I have tried. It is only since flashing the most recent version of UnOriginal that I have had any success with anything else.
Knock on wood, I have had excellent results with everything I have flashed.
Thanks for the feedback. I have quite a bit to go on now and am confident I will find and annihilate the culprit. Plus I found some more threads that were right in front of me.
For some chucked up reason it will not let me say thanks to anyone. What a crock of #$%. So, "Thanks"! I promise to come back later and thank everyone properly.
Thanks for the heads up on the 2000mah battery. I'll check it out.

I'm glad that you like my ROM, just so you know it is not UCKK6 it is UCKH7. UCKK6 has broken drivers which will cause poor battery life.
Good luck and happy tweaking!

I won't be doing anything for a while, I'm too OCD about smoothness and battery life.
I'm noticing this too. With my "tablet" micro-minimal usage, each hour of everything OFF and it laying on the desk takes about 1% of battery. Why? I deleted even more "bloatware" in my opinion, set cpu on a pretty conservative diet, etc. Never had this issue on bone stock ATT rom, ever.
When I started this thread I was losing 10-15% an hour and could not determine why. It was not one of the usual villains as far as I could tell and Better Battery Stats was not giving me the answers I was looking for. So, I simply started over from scratch and now, even with sync, FB, WWF, and GPS active, I get exceptional battery life. I wish I could have pin pointed the culprit, but unfortunately I did not.

I just installed the new Rom TRIGGER 3.3-beta. This rom is very fast and the GPS is great. I also put on bali 1.8.4. But the battery drains fast. If you guys tried it out, and found a way to save battery can you please let tell us what you did to control it. I know its in beta version and is being tweaked on.
Thank you
Yea Im using the same Rom. Hate to break it to you but the battery life on most all android devices sucks. I have had 5 different android devices and the battery sucked on all of them. didn't matter if it was stock or custom Rom. ether way these devices just have ****ty battery life. You can make it a little better by turning down brightness and messing with other settings but when it comes down to it. it still sucks! Just my 2 cents!

Did you recondition your battery after flashing? I've had pretty good battery performance with the Bali kernels. I also tend to use the KB1 modem. It seems to give me the best battery. But each phone is a bit individualistic, and what works well for someone may not work as well for next person.

This is untrue as I have owned an android device since the G1. The battery did suck on the G1, but by no means does the battery suck on every android device. My guess is you probably never calibrated your battery or you just used it very heavily. There's also the possibility that every rom you tried sucked on those devices. I have consistently gotten a full day or more with Bionix NextGen V2 with the Bali kernel with moderate to heavy usage. It is true if you lower the brightness,turn off wifi,bluetooth and gps when you aren't using it that it will increase your battery life though.
I have reconfigured the battery and have the brightness turned all the way down. Dont use WiFi but battery still sucks compared to other smart phones.

can any of you post a screenie of this rom pls
Battery usage is hard to compare since there are so many variables. In my experience I generally have better battery life when visiting my parents. The area I live in is somewhat of a black hole for signal and I notice more battery drain here with the same rom/kernal setup and similar usage pattern. I believe the weak signal here causes a higher battery drain over all.
Of course this might not apply to your situation but it could be worth considering.

I'm not going to argue with you, I'm just going to state what the facts are.
THE BATTERY DOES NOT SUCK, MOST LIKELY IS USER ERROR
Lol. It isn't user error. I think you might just use your phone more heavily than others. One thing you have to realize when comparing the battery life of the phones are a) battery size, b) screen size, c) smartphone or stone age phone, d)**** you've done to the phone including ROM's/Kernals/Apps/Sync.
Personally, on days that I am working, I get about 8-10 hours out of my battery before it dies. When I am not at work I get about 23 hours out of my battery.
what is the major difference between trigger 3.2 and trigger 3.3?
Try using overstock instead, I've had pretty good battery life with it.
Im running trigger3.3 beta with overstock and the battery is great.

bahaha you must be kidding. like someone else said, it depends on soooo many variables and phones. I was running trigger rom and overstock kernel and was going down about 1-2% battery every hour while screen was off. I listen to pandora every morning for an hour to hour and half and would go down 5%. I've sat on the web watching tv on TV shows stream app for about 1-2 hours and went down like 15-20% when brightness is lowered.
It's all about the brightness, killing apps that enjoy sucking battery life and enjoy run constantly, and running an OC/UV kernel. You can also change it from the usual 3g/H connection down to E (edge) which uses alot less power also. Turn off or turn down auto sync on certain apps like facebook from every 10 minutes down to every few hours.
The screen is the biggest power consumer, so lower that, set it to automatic or all the way down to lowest brightness to save quite a bit of battery when using the phone.
Usually the second largest power consumer (if ur not a huge user of just one certain app) is when the screen is off and the phone is syncing and just running android. the solution is If you can find a decent UV kernel (overstock for android 2.2 was what I was using when on 2.2), you can slow your CPU down. Like on my vibrant I made a profile (on the SetCPU app) to undervolt it from 1,000mhz down to a conservative 400mhz max and 100mhz minimum when screen is off. This is very easy to do. sometimes I'd watch shows on that. I usually left it at a conservative setting and 800mhz and 100mhz min all day long when screen was on, sometimes at 400mhz if i wasnt doing much. It worked wonderfully for me.
Moral of the story, there are plenty of things to make your phones battery last longer than it normally would. The big one probably to get a well known kernel that can UV, then get SetCPU and make a few profiles to make your phone use less power.
BOOM!
I am still on 2.2 froyo and waiting for the official gingerbread update. I remember reading that 2.3.4 ginger bread was supposed to improve battery life.

My battery has been pretty miserable after switching to 2.3.4. I'm a pretty heavy user, but before the switch, it usually lasted a whole day. Now, I'd be happy to get 10 hours. It's not so much of a problem for me, because I can usually get to an outlet to give it a bump charge during the day. I would definitely switch back to a 2.2 build if it wasn't for the CRT animation. That's probably my favorite addition to Android 2.3.
This has been discussed before and some people found that battery life is improved by freezing some social apps.
The battery on my Atrix lasts about sixteen hours.

My battery lats very long. I can go on an all day cycling trip, where I'm being gps tracked the whole time with a cycling app, location updated to the cloud on google latitude, checking in at new places I visit on foursquare and google+, taking and uploading photos along the way, some SMS, some email, etc, and I get home and the battery is at 60%.
On work days, it's off the charger at 7am, and when I go to bed around midnight it's still over 50%. WiFi on, Bluetooth on (and paired to a stereo headset to listen to music for a couple hours each day on the bus to Redmond), doing nothing at all to conserve battery.
I bought a spare battery because I just got the phone when the HKTW build leaked, and everyone was saying the battery life was atrocious. I take it with me when I'm going to be away from electricity all day, but have yet to even come close to needing it.
Mine sucked bigtime whatever i tried, so i'm back to froyo

Yes most battery consumption (52%) comee from phone idle than in second place is screen and the app that uses the most is pulse but only 7% and I spend lot of time using it. Reconsidering going back to 4.1.8.3

One time I did see horrendous battery life, and it was just after I installed Google+ and enabled the auto upload feature. Unbeknownst to me, it scanned my SD card and was uploading everything, not just new images. Hours of the phone being warm in my pocket should have indicated something was up.
When I checked, it was "phone idle" taking up all the battery. Those seeing phone idle high up on the list, are you on baseband 01.97.00R? I know I wasn't initially, but then flashed it wondering about 4G speeds and such. Didn't improve my speeds, but I don't see phone idle up high on my list.

I configured my Google+ instant upload feature only to start uploading when I plug the charger in and when I'm using wifi (when I get home). Currently using baseband 01.77.15P don't know what else could it be. I think its because the hktw is only a beta release
Sent from my MB860 using XDA Premium App
definitely very beta. The key thing to take away from all the bugs people have discovered is that it is very inconsistent. Seems like no two people experience the same set of issues.
To the OP: give it a try on a day you'll be near power, and if the battery life is poor for you after doing tweaks (like Navalynt's mod which packages up a lot of the fixes people have made), go back to 2.2. Simple enough.
I have been running it as my main build and it works fine here for battery. Been flying around and this thing has been working great. Average of about 13 hours on some good usage (watching 1 hour video podcast and a lot of audio podcasts) wifi and gps on , streamed espn for an hour and a bunch more and still working great.
THe battery has been conditioned here and there and working good but I will always check the usage and see whats eating it and freeze those that I dont need. That always helps everyone.

Hi all, I'm new to this part of the xda forums as I had a nexus before, just got the upgrade to the Atrix, rooting,unlocking of bootloader everything went well but I just flashed Aura's from with feux kernel and im getting really really bad battery life, like I'm talking 4-5 hours. There is one process thats really confusing me, its just called "x" and its sitting there taking about 35% battery, my screen is taking 55% battery.
It's getting really annoying as my nexus used to give me about 12 hours and the only reason I moved to the atrix was to get the better battery life that I saw with all my atrix touting friends (they all had 1-2 days battery life) I'm about to flash homebase and see if that fixes it but I don't know whats going on. I have a UK MB860 and I used http://forum.xda-developers.com/showthread.php?t=1196747&highlight=t-mobile+root to root. Pleaseee can someone help!
X is the webtop and there is a fix somewhere for that (doesn't completely work). Just flash CM7 beta. Its much better than any other ROM and has the best battery life. Everything except the finger print scanner and webtop work.
Also I had really good battery on the Ying Yang ROM.

I was just about to post that lol. Also make sure every time you flash a new rom you are at 100% if not that is a sure fire way to cheat yourself out of battery life. I don't know if I'm just one of "the lucky ones" but I easily get over 16+ hours with moderate usage. I'm running CM7 beta with quite a few things frozen.
Ok so I followed the guide to perfection and it didn't improve the battery life one bit! I'm trying hard to find a t-mobile radio I can flash as I have read around it could be my radio that is the culprit and I am also getting rubbish HSDPA readings, I should be getting full bars but since switching to homebase Im only getting one bar.
Using watchdog I have noticed that the Xorg process is using over 50% cpu which does not seem right to be and I believe that because its a linux process Watchdog can't kill it. Is there anyway of fixing this?
1) Uninstall Tango, Facebook and Handcent SMS if any of the three are installed. They are huge battery drainers and you can find less battery hogging substitutes
2) Freeze any unnecessary apps, I believe there is a thread somewhere in the General section that has a pretty decent freeze list (if you flash CM7, you will have very little to freeze but that's good!)
3) Keep brightness down to a minimum when you can, I've noticed kicking the brightness up rather high can be pretty demanding on your battery
4) Set SetCPU Profiles to something like this...
Screen Off 216/216
Charging 1100/216
In Call 456/216
Battery <20% 456/216
Battery <10% 216/216
5) If you have the proper kernel set the CPU govner to power saver.
6) Undervolt, test yours and never apply set on boot unless you are positive it's stable, mine are something like this...
1100 MHz -50mV
1000 MHz -50mV
912 MHz -50mV
750 MHz -50mV
608 MHz -100mV
456 MHz -150mV
216 MHz -200mV
This way when you're phone is idling with the screen off, in a call or low on battery it is undervolting heavily to save maximum amounts of battery
With this setup I can get 30+ hours pretty regularly with moderate-to-heavy usage (weekdays/non-work days), 22-25 hours with more heavy usage (work days) and close to 48 hours with little usage (weekends).
It all depends on your usage and your phone but I have found this setup here to work fairly well.
I am currently on CM7 Beta, stock CM7 radio and stock CM7 kernel, running at 1100/216 when above profile conditions aren't met. 32% been running since 9 am this morning, it is now 3:15 am, today was a long workday.
I can almost guarantee (almost) that its your rom/kernel combination. Had same problem til I changed.

That will nuke your webtop & fix your problem.
I'm now using faux kernel for CM7 and that hasn't improved anything, in fact I think it it has made it worse. It's getting really irretating because using the watch dog app it always says there is one linux process on every rom I use that is clocking at over 50% cpu usage and It won't let me kill it (probably because it's a linux process), its really annoying me because all I want is my phone to work properly but to enjoy the full rooting experience. I know countless amounts of people with atrix's and they get a full day and a bit out of their phone with heavy usage i can't even manage 10 hours!

Watchdog eats battery like a mthrfckr, get away from that. Install BetterBatterStats instead & look for wakelocks. Which linux process are you noticing with that high cpu usage?
How many hours of screen time do you get in those 10 hrs?
Have you tried with a fastboot wipe & internal storage format prior to installing a new rom? Are you using the latest recommended radio for your phone?

Turn background syncing off if you are using that, and get in the habit of doing manual updates.
Too many times (with ANY Android device) people leave background syncing on and it tries sending/receiving data in a weak signal spot when you don't realize it. That's like a hot knife through butter on a battery.
Leave syncing off permanently if possible! That's a huge improvement right there for anyone...

I've been using the latest gingerbread builds and I'm having great battery life, But I notice when I use AOKP or any kind of ICS rom my battery life isnt so great..
Is there a specific kernel you people are using? and What kernel settings are working the best for you?
Thanks!

Good news that you are not alone. Based on my premature calculation, only 10 out of 100 (that's 10% ) ICS ROM users have good - great battery life, meaning the rest is having worse. Mine is falling into that group. I never have great battery, only so-so and below average.
Also as Nick has mentioned, asking for which best is a NO NO here.
One might be good for me, doesn't mean it will be good for you and vice versa.
Try them all and pick one that best suite for you.
My 2 cents......I know you have read this several times - but battery life is really dependent on a lot of factors - your AT&T signal, rogue apps, data sync frequency, CPU governor etc. etc.
read Entropy's excelled thread on battery drain on this forum.
i tried out a few GB roms over the last few weeks and really did not notice any battery improvement over ICS.
Currently running cMIUI with xxkernel and it is really working out great as in the battery easily lasts for the whole day.
I remember when I was on stock GB I could go upto 2 days on single charge - but that may be due to the battery being brand new. I have read that the battery in SGS2 really degrades fast
I have 2% drain per hour when doing absolutely nothing, screen off, wifi off, gps off during 8 hours overnite.
While someone has reported having only 2% or 3% drain over 8 hours overnite.

Have you tried using "Better Batter Stats" to see what is causing the drain?
I have been using AOKP since Task brought it to us and I average 1% every two hours over nite.
Do you use the Facebook app? That sucker is hungry for your juice.

I got BBS v1.7 for a while, that was absolutely no help.
I installed BBS 1.8 for about a week. Based on their info, I got the "multipdp" along with some other things (such wake-lock) cranked up big time.
I read the Entropy thread, not much help.
Note: Wifi is off.
Maybe 3G/H+ keep toggling for sync process?
I do use facebook! haha. and I havent used better battery stats

I'd also recommend using CPU Spy in conjunction with Better Battery Stats to see if the phone is able to enter deep sleep.
I don't get as good as you. . .I average about 1% or less per hour overnight. But that's with wifi on, periodic syncing of 7 accounts, scheduled backups and cache cleaning going on.

My understanding is multipdp will show when apps are waking the radio to use cell data - each wake instance results in a minimum of 6 seconds of wakelock. Switching to wifi when you are idle "should" eliminate this wakelock.
I could be wrong here...dig into the known battery drainers thread from around the time the first ICS roms were being tried on the i777. There was some discussion of it...it is a renamed version of some other wakelock in GB.

That's what I said, "maybe 3G/H+ toggling".
I believed that if I left wifi on overnite, do nothing, I still had 2% drain per hour.
Let me completely turn off data tonite and see how thing goes.
errrrr I have a huge problem with my battery. I've been testing various ICS roms and kernels(aokp, foxhound, serendipidity, fluxxi Kernel, siyah 3.4.3.,Neak) and all of them with the exception of serendipity w/siyah kernel, drain my battery real fast.
Not really sure what the problem is but when I look at what's been using the battery its most of the time either screen (which is understandable) and android os? I went to bed last night leaving my phone at 100% and woke up to find it at 52%. When I looked at what was using the battery it displayed, 93% android os and only 3% cell standby??(btw Foxhound ICS, Siyah Kernel) Maybe I have to many things updating/syncing?
When I first got my phone, 2-3% battery drain overnight was one of the things that amazed me about stock gingerbread on the i777.
I've flashed alot of roms since then, and so far, no ROM can even touch that stat.
Hello,
I was wondering which rom you guys could recommend for better than stock battery life? Seems like a lot of the roms are tweaked for smoothness and speed not battery life. Currently on d3rpICS but the battery life isn't so great...barely getting 8 hours with 1 hour on screen time. If anyone could point me in the right direction I'd appreciate it. Thanks!
Meanrom ICS comes to mind. Your kernel can also play a role on battery life too. Overclocking will drain your battery, so will certain governors. Experiment around a lil bit to see what settings work for you.

How are you only getting 1 hour of screen on time? I suspect something else is the issue. Are you in an area with poor signal reception (that is usually my worst battery drainer)? Or maybe you have a runaway app. I recommend that you download Better Battery Stats XDA to monitor what apps are eating your battery.
Maybe you could try a fresh install of the ROM, but leave off the extra apps and see how it runs.

No I'm not in an area with poor reception...and the ROM was a clean install I haven't even put anything back on. I'll give meanrom a try and see how that goes. Thank you.
Coolexe's kernel UV's the screen, i'm getting 4+ hours scraping 5 hours+ on screen tme ... note not using 3g, i find 3g canes my battery.
tips.. stop the media service in running apps 'the one that often gets stuck restarting' .. mediadbmservice or something, i can't find anything that doesn't work after disabling
running 1188 -ondemand, cpu1 not forced always on and gpu3d/2d/266/200 using 'kernel tuner' and a small undervolt.. all 1xxx up to 1188 frequencies set at 1.0
I also stop apps that i don't need after their use, including 'kernel tuner', I know your not supposed to but i haven't seen any ill effect so far.
