Hi,
all Rom threads have a rather big amount of discussions about battery life. It seems battery life varies between 8 hours to several days. Several reasons for this are addressed and one might check this first before anything else
1. Usage. If you use your phone you discharge it. Use it heavily with all whistle and bells turned on and you discharge it quickly.
2. Apps. Some apps like to phone home, sending or fetching frequently data. For some apps this is obvious. However, some might be hidding this or they are just bad programmed.
Using Powertutor and juiceplotter help to identify those battery eating apps. E. g., VoIP- or Mailclients, etc. are candidates being for battery sucking monsters.
3. Signal reception might make a different. The radio modules trying to minimize the sending power to save battery. If you put the phone in an box, bag or whatever the radio module might switch to a higher sending level to reach the cell tower.
In general you can't do much, simply choice "good" locations wherever possible.
4. Cell search and switching. Using a train or any other fast moving vehicle might require to switch very frequently between different cell towers. Every switch consumes power since data will be exchanged. If no cell signal is found the phone starts searching for one which consumes more power. Switch to flight mode if possible.
This are already steps which helps to safe a big chunk of the batteryand all this steps are completely rom independent.
In my opinion roms might contribute only to a small amount to the battery power. Maybe there is a buggy program or some settings are not optimized. However any more or less stable Rom should result in a rather similar battery life time.
Same is true for the kernel. Sure undervoltage, different schedulers, etc. might all change something regarding the power consumption. However this could not explain this very different reported battery life times. Its more in the range of +- 2 hours.
I know it was discussed sometimes already. I believe that some reported battery problems are due to a wrong combination of libs and settings for the used radio module.
Many people upgraded to the newest radio, however the local carrier might slightly modified settings to there specific needs. Furthermore, the might use a special tailored library enhanced by functions for there particular network.
This was given, at least for the Japanese carrier Softbank.
build.prop contains some special calls and a look into the library libhtc_ril show corresponding functions.
If roms carrier a different version of libhtc_ril and does not call settings in build.prop people on the particular carrier might observe battery drains.
Even worth the present situation creates random combination of radio firmware, build.prop, and libhtc_ril.
What might be needed is a installation routine for a Rom, which is capable to modify and replace above mentioned files for the given carrier.
I know that this would work since I'm doing it manually every time I install a different rom.
Would be glad to hear other opinions on this topic.
sure, the use of my phone make different battery drain but with the same use, this same battery drain change with the rom installed in this same phone! and the radio or the kernel of this same rom can make also difference in the battery drain (cf DeFroST for exemple...) with a scale between 8 and 20 hours!!! so i think the rom have a lot importance in battery drain ;-)
Hi,
I think one has to differentiate between an potential bug in a rom which might drain the battery and a "stable" rom.
From the technical point you can tweak rom and kernel to the max but this would never result in 4 times longer battery.
I would not say thay you can't get a kernel highly optimized for performance which might drain much more. However, in general all roms come with power-savvy kernels the small differences between those kernels could in my opinion not make such a big differences.
Same is well known for laptops. Sure a stock kernel might drain faster but even if I tweak out the very last options in the kernel settings I could never improve battery life time by 400%. That would be instead of 2 hours my laptop would suddenly hold 8 or more hours.
I belive the same is true to roms. There are some which emphase light the use of light apps and avoid animations and other battery eating eye candy. However, it can't result in an difference of 3-4 times, unlike something is simply wrong within the rom.
The main point is, nobody seems to give attention to the different modifications different carriers introduce in stock roms.
Thus, using a rom for which libs and settings come originally from T-mobile UK might fail heavily for Softbank Japan, or Verizon US.
What would be needed is
1. Awareness of the different carrier-based settings.
2. An application which is capable to modify and replace the mentioned files specific for the used carrier.
Definitely,the battery life should be associated with ROM.The models of running ROM are different-----how the SD card works..
My friend has a G2 but no xda account so he asked me to come here and ask you guys what's the best G2 ROM with great battery. Were going on a 14 hour trip and were going need it too last. Any advice? On ROM and kernels
Sent from my HTC Glacier using XDA App
It depends on what you will be doing with it. Any ROM can be made to last 14 hours if you have a battery in good condition and only use it occasionally to check e-mail, visit a few web sites, etc. My Desire Z easily holds up to a full day that way. OTOH, if you're playing games all day long or watching 14 hours of movies, then no ROM will help. You will need an extended battery at that point, or some other way of recharging the battery.
In my experience, although people make claims about how good one ROMs battery life is over another, I have yet to see any convincing evidence. People's usage patterns and phone environment are far too different to be able to say that one particular ROM makes a consistent, noticeable difference. If anyone has actually published scientific results studying this, please point me to them.
As almost all ROMs are derived from a common code base and run on the same hardware, I would focus more on a ROMs usability, speed, feature mix and stability.
+1 to the post above. It is all predicated on how you use your phone and for what, also if you use setCPU or use the tweaKr script (like me), it depends on your profiles and governors. I personally have great battery life using the latest meXdroidMod release for the G2, but I'm very careful to always calibrate my battery between flashing roms. MeXdroidMod is the only one to my knowledge that uses waydownsouth's tweaKr script that allows you to undervolt your processor and set profiles for your CPU that react much faster than setCPU does. My advice is find a rom that you like and make sure to wipe battery stats then use the battery calibration app. Good luck and happy flashing!

Any sense based rom like Unity will be processor intensive, so I don't think it would last nearly as long as an ASOP build. Also the unity dev team has pulled all their download links from xda and their website, so unless you find someone willing to share I don't think you'll have much luck.

I have unity 3.0. I get about 10-12 hours of battery life. Here are some ideas that i use:
-download juice defender
-set max sleep cpu speeds at 368mhz
-processor is set to 1.2 ghz by default. Set it to 800mhz

Exactly. I guess this is where YMMV definitely comes in handy. All the ROMs I've used I can easily get more than half a day out of them with my daily use. I shut off data when at work and turn it on on my breaks to browse the web, check emails etc.
There is the G-Lite rom from the Virtuous guys. I haven't tried it out but the other roms I've used from them are great. It's not Sense tho, it's ASOP.
http://forum.xda-developers.com/showthread.php?t=1076786
+1 for G-Lite rom. With version 1.0.2. i could consistently get 2-2.5 days on a single charge.
Asking what the best ROM battery life is is like asking what the best bass for metal is hiding: ). It really depends on your phone, and how heavy of a user you are. But if you want an actual answer, I get the best battery life with Xboarder's Stock Gingerbread ROM.
With all these tweaks, ROMS, and kernels out there to completely customize your Evo or whatever phone you have. My question is, how to make sure to you don't over do it.
I know that I will look at signatures and see what posters have done to their evos...and try some of those things myself. You can see my signature to see what I've done too.
I am a noob, but I have almost graduated to the next level (whatever that may be). There might be several people like myself who sees all these tweaks and tweaks out themselves in excitement over what you can do to your new toy.
I get the feeling that some tweaks (kernels, CPU governors, ROMS) can often have functions that can overlap and actually worsen performance rather then improve.
As a request to all those who have conquered the realm of the Evo and aid us lowly lifeforms in modding our phones, can you help us figure out what is just right, not enough, or too much? Besides, too much of a good thing can be bad...
We can start off with my Evo. Been using Linpack as a reference for performance, and have averaged 36.5 MFLOPS on single thread. How does this stack up?
Interesting, and i am by no means an expert, but here some things I have found out.
Don't use Collins ph battery tweak and Setcpu together. Your CPU will peg and kill your battery life.
Setcpu with a Screenoff profile is unnecessary if you have the kernel governor set to smartass. Smartass sets the cpu to 384 with the screenoff anyway.
Don't let your daughter take your EVO in the tub. That limits performance as well.
Add in that benchmark apps, like Linpack, are worthless.
You couldn't hit "too much". Believe me, there are people who flash things daily. Some several times a day. And think about how many mod flashes a dev does to his phone?
I meant running at once...

Too many things running at once. I figure these phones can handle a lot given the roms people float between...
And you have to remember that all phones are different and that just because I can do something that works great on my phone doesn't mean it will do anything for yours. Or make it worse... Just sayin'

This question is also hard to answer because peoples taste varies so much.
A good example is myself, I like Sense, but I could care less if it is version 1, 2, or 3, I just want it to work good with no problems. I have never seen a theme that I liked better than stock with just a nice photo as a background. In fact, I could really care less what it looks like as long as everything works well when I want to use it. On the other hand, I have almost no use for any of the bloat apps that came with the phone. I remove almost all of them, Including Facebook, the stock browser, the calender and all Sprint specific apps. But I do have a lot of apps on my phone, about 141 user apps, last time I checked for a total of 264 total apps, including the system apps I have left.
I run Fresh 4.2 rom, that I have modified by removing the aforementioned Sprint bloat and built in apps that I don't want or need. I like Flipz rom's the best because they are stable, reliable, and not updated every day, because no update is needed. Plus he removes the CIQ, which runs all the time in the background. I run a kernel that gives me the best performance and responsiveness, with no-sbc and features like HDMI mirroring and 5-point multi-touch, but other than that pretty much stock (trying out various kernels now so can't say which one I will end up going with). The only other mods I have done is I have changed the splash screen, because the white one would wake up my wife when I would boot my phone in bed at night. I also made a battery indicator mod that reads percentage and is easier to see. And I am running the V6 script to eliminate the Sense reloads when exiting apps.
Works for me, but I am sure a lot of guys/girls wouldn't like it at all. So, in the end, it really doesn't matter what I am running, unless someone else has the same tastes as me. And isn't that really the point?
I think I do a lot for my phone. But not too much. Everything in my sig + setcpu, chainfire 3d, juice defender etc
Deck's + SZ + SuperCharger script + ViperMod script.

How much becomes too much the day you bork your phone when you tweaked something you shouldn't have tweaked, and then turn to the forums for help, only to get an attitude at the people who are trying to help you fix your own f'up. That is when it becomes too much.

I dont use my phone a lot and my TWAS is usually 0%. I dont use my phone alot, but usually when 5-6 hrs of no use or very light use it has gone down around 20-30%. Anyone have any ideas of what rom would work best for me? I am on ICS 5.0 right now and it seems they are not coming back with their 5.5 they had out. I really only care about great battery life and having some type of hotspot hack or free tethering.
Thanks.
You have to try each one and see what works best for you. Read the ROM threads. Every phone and user is different.

I have been using the latest sleeper rom and i have left it at 1000mhz no overclocking and i seem to be getting better battery life than i was with some of the others. i flash frequently and i would agree with kennyglass in that each one works differently. so try for youself.
Well, like everyone else said, its depends on what your phones handles. Everyone phones handles a rom differently, well, not that differently, but enough to make big differences.
Like the guy above me, I also use SleeperRom. Its a very stable, battery efficient rom.
here is a list of roms I would try out...
ACS_ICS_V5.5
LegendaryRom
MarcusantROM
StarskyROM1.5
I also recommend CleanGB by toadlife. Fast, clean, stable, full day on original stock battery.

I personally would towards 'which kernel should I use?' You've got to remember that although we all have epics, not every CPU is the same. What I am running it he or she is running may not be what you should be running. If you ever check out an oc/uv thread, you will see that people get different results using different settings, even though we're all on epics. You've got to try a couple different setups (roms AND kernels) to see which runs best for your device. Good luck!
via my EPICally transmogrified EI22: adrenaline injected & Supercharged
I currently use CleanGB which has been pretty great. If you're in an area with iffy service, that'll kill your phones battery pretty quick.
After installing a new rom make sure you charge it to 100%, wipe battery stats and then let it die without charging to get the most out of your battery (and having an accurate battery indicator)
In my opinion the way you configure your phone has by far the biggest effect on battery life, followed closely by the signal strength of the area you are in, with maybe a very small effect caused by the rom/kernel combination. Watch what you have syncing. Facebook and Twitter syncs can kill your battery, as can any other app that's always using data. Also, wifi uses WAY less battery than 3G or 4G. Use it when you can.
I'm on stock EI22 with mkasick's kernel and I usually get a full 16 hours with power to spare.

Basically Poit. Since no 2 people use their phone the same way it is retarded to ask for a comparison of best battery life. People need to stop being lazy and just try the ROMs out and compare for themselves based on their own use.

I agree. I have seen 3 questions over the last 2 days with these dumb questions.
but if I was to give my advice, I would strongly advise trying MarcusantROM, Battery life is pretty amazing, just be sure to flash a different kernel, as 2.0.6 is not even offered for download anymore because of bugs n such.
I would strongly advise the Shadow Kernel, paired up with MarcusantRom. You should see some pretty amazing battery life with that combo.
or try these out...
LegendaryROM
SleeperROM
Come on... "Dumb question"? "Lazy"? Get off your high horse. Certain ROMs give better battery performance than others because of certain tweaks and the OP asked for some general advice. Certain ROMs are certainly worse than others. OP wasn't asking for what would be best for him but what has worked good for others. Why is it so wrong for someone to ask for general advice about a ROM/Kernel combo. Not that hard of a question and not so ambiguous that it deserves a "dumb question" or "stop being lazy" response. If you don't want to help the OP, then simply DON'T RESPOND.
As for the question... I generally use the kernel that is included with the ROMs because normally that is what the developer has tested the most. I think Thunderhawk, Sleeper, and Legendary (in that order) are all good for battery but I haven't used all of the others.

In kind if you don't like the responses don't respond to them. I read for a month all the ROM threads before deciding on one to flash. Go to ANY ROM thread and someone there will claim they got the best battrery life there. It is different for every body and EVERY phone. ALL of the ROMs here have tweaks that work differently for everyone depending on use. Also people are sick of every other thread as "what's the best ROM". You HAVE to try them for yourself. If we are being to real for you then don't read what is written.
I was once where you are now. When I couldn't find a satisfactory answer, I made my own solution. I'll be uploading the latest version of it, version 3.3 today or tomorrow.
Battery Used: Extended Battery 2700 mah
Testing Performed: Idle Only
For those unsure, idle testing is simply when you treat your smartphone more like a phone. This included uses such as, checking the weather, responding to the occasional text, checking the time, etc. The primary goal of idle testing is to understand how long the phone can stay alive when used for texting and phone calls only. This is useful primarily for occasions such as, going on vacation, where you would like your phone to last a week or more in case of emergencies, but you'll be preoccupied and not killing your battery with Angry Birds. It's nice to know that our phone is capable older, simpler cellphones in standby time.
This indicates that my phone could stay on for as long as 10 to 14 days.
Direct arithmetic calculations indicate as much as 5.5 to 8 days on the stock 1500 mah battery.
Obviously, usage varies greatly between people and even between days, so anything other than idle testing is subjective. Testing was not performed on a stock installation, but rather, on my own daily personal fully-decked setup.
On the stock battery, I've played games for a total of more than 3 hours over a 48 hour time period before needing to recharge.
This has held true on my phone, my wife's, her mother's, and more than a thousand other user's phones. Yours may vary. Try them all. I do.
Looking forward to Random's latest!

I have to say I have tried EVERY ROM on the SGH-T989 and can say none are as stable and have the battery life to match the stock ROM.
I tried Darkside today. It is a clean ROM. Close to stock. I had two complete lockups on the phone that required battery removal in about a 6 hour period. I am not overclocking at all. The ROM has an underclock by default.
I just think it's time to give Samsung and the programmers there a thumbs up for doing such a great job on this phone.
It would be nice if they could release more of the header and source so the developers here could have a better chance of getting a stable ROM built...but until that happens I will just stay with a rooted and stock ROM.
Peace.
I've had no lockups or any problems in the 150 hour uptime I had with Juggernaut 5.0 with 009m faux's kernel.
Battery life is much better as well. Dropping down to 80% after 1 hour of display time.
Cool story bro

I was on the stock ROM for 6 hours yesterday. Surfing, playing games, wifi enabled. Used a bit over 30% from a full charge.
I jumped right into custom ROM's when I got this phone. After going back to stock is when I realized how much the custom ROM's actually degrade the phone.
I have ran Jugg's 4.x with Faux kernel and Bullet kernels. Bullet was faster by a good bit. Battery sucker from hell though.
Do these phones really need the overclocks and tweaks? After going back to stock my opinion is no.

You probably didnt follow the directions when installing any of the roms you tried.
If companies like samsung were as awesome as you say they are, would XDA exist at all in the 1st place?

Keep it civil and to the point. Don't attack my character by implying that I don't know how to follow directions and flash a ROM. I have been a member on XDA since the first year....much longer than you.
I don't have a problem with bloatware. I use a stock ROOTED ROM and remove the bloatware. Very easy to test and then delete bloatware using Titanium Backup.
XDA got it's start back when the CPU and chipsets on phones were very slow. Over time the new phones have become handheld computers. The processing speed is much faster.
In the beginning the OS's were in the infantile stages as well. They have all improved dramatically.
I remember when a flash on something like the HTC Tytan made a huge difference. You were getting the GPS and FM Radio Unlocked. The bloatware was removed in the ROM(Windows based...no ROOT access). It made a huge difference in the performance of the phone and unlocked a lot of features.
This isn't the case with the new phones. There really is nothing being added to the ROM's that can't be added via the market or removed using Titanium Backup.
What I have seen with every ROM is intermittent lockups that require battery removal and excessive battery consumption probably from the aggressive timings that aren't necessary.
Peace.

Please include multiple kernels as you test various ROMs, especially faux and Synergy
And perhaps install Juice Defender as a best case.
Personally I haven't experienced any lockups with the two custom T989 ROMs I've tested, but have benefited from the improved battery life dramatically. I'd still love to see a more controlled experiment, however.

Read it. It is basically a generic thread. No stats or true testing methods just some user comments.
I want to actually test the phone in real life conditions. Watch some vids, talk on the phone, skype/gtalk/YM video call...etc. Actually run consecutive tests across the best ROMS and stock and see how they match up.
Benchmarking is a bit ridiculous....in several aspects.
If a game runs 30 fps or greater...you won't see the difference.
If a game runs a stable 30 fps versus a ROM that peaks at 50 but valleys at 15....you will definitely see the difference.
If a ROM runs 50 fps versus 30 and both are stable...you won't see the difference. The question then is which one uses less battery. The obvious answer is the one running 30fps. Less frames means less redraws and less CPU and GPU.
I just want to once an for all be able to definitively say what each ROM is really doing to the phone with graphs.
Not hard to do. Just takes a real world test model and some time. I think I can test one ROM a day. I will test the most popular ROM's....Juggs, Beast, Darkside, Bombardier, Gingersnap, etc... I have tested them all. I know which ones are legit and which ones aren't.

I don't have a problem with bloatware. I use a stock ROOTED ROM and remove the bloatware. Very easy to test and then delete bloatware using Titanium Backup.
XDA got it's start back when the CPU and chipsets on phones were very slow. Over time the new phones have become handheld computers. The processing speed is much faster.
In the beginning the OS's were in the infantile stages as well. They have all improved dramatically.
I remember when a flash on something like the HTC Tytan made a huge difference. You were getting the GPS and FM Radio Unlocked. The bloatware was removed in the ROM(Windows based...no ROOT access). It made a huge difference in the performance of the phone and unlocked a lot of features.
This isn't the case with the new phones. There really is nothing being added to the ROM's that can't be added via the market or removed using Titanium Backup.
What I have seen with every ROM is intermittent lockups that require battery removal and excessive battery consumption probably from the aggressive timings that aren't necessary.

Agree 100%
Nothing has performed better than stock 2.3.6, rooted and debloated.

I run Juggernaut 5, ADW launcher, AOSP ICS themed, with Darkside's latest kernel (extracted it from Darkside ROM pakage), and I've had amazing battery life, OC'd to 1.83ghz with ondemand governor.
And IMO Touchwiz is ugly, samsung tries too hard to make all their stuff look like the iPhone. They do a crappy job of it and it ends up being a dissapointment.
I think any small degradation of battery life is worth the noticable boost in snappiness and cosmetics of the phone. I personally couldn't stand the stock phone, as soon as I could I flashed something different.

Strictly aesthetics can be achieved through the use of different launchers/lockscreens. The point of ROMs/Kernels need to be more than aesthetics. Hence, "some" of the ROMs offered [strictly speaking] are a pretty big disappointment because they're nothing more than themed stuff baked in and offer no real functionality.
I'm REALLY interested in a controlled experiment of battery claims of different ROMs/kernels. Preferably all at stock speeds.

Sorry but there is absolutely NO proof in these pictures.
I can see that your phone was on battery for a bit over 1 day.
I can also see that 45% of your phones battery usage was the display...and that the display was on for a bit over 7 hours.
What I don't know is what was your screen brightness set at?
Does the display percentage represent JUST the LED power for the screen or does it also include the GPU/CPU driving the display?
Where are the numbers for the stock ROM?
Those numbers mean nothing when you don't have a standardized test bed and procedure.
Peace.

You can use a home launcher on the stock debloated ROM and get the same results with more stability and better battery life.
I recommend you check DXHOME out to see a smooth launcher.
Peace.

Actually, unless that test was completely skewed (e.g. screen on displaying black screen), 7 hours of screen on time + 20 odd hours of standby time with use of radios/connectivity is very very impressive.

I agree with your first paragraph 100% and will get the experiment underway with Stock speeds.
Peace.

When you can refer us to pictures of a base ROM with the same parameters and settings for comparison then I might say it is impressive. But with no base ROM data it is purely speculation.
Peace.
enjoy the drm laden ciq enabled features... That cannot be removed by titanium unless it can magically decompile recompile frameworks on the fly...
Enjoy the Memeroy leaked jobsmanager....
Anyways now thats oout of the way
How much time did you spend between stock firmwares and custom firmwares?
Did you fully wipe the device before flashing and after
Did you do dirty nanoid restores?
A little more info woud be helpfull
at the end of the day if you enjoy stock more great for you.... Use it n move on...
Still missing the point of this thread on a dev website unless you like being trolled.
