Ways to increase battery life? - Thunderbolt General

My wife uses a rooted Bolt running Virus' Eternity ROM with Sense 3.5. I'm open to trying new ROMs and other less drastic measures as well. I've thought about switching to an AOSP ROM that might free up more memory. I personally use Liquid Smooth and have been trying tweaks to see if my battery life improves before trying to change hers. She uses the FM Radio a lot at work which is the primary culprit of her battery consumption. It's generally fully dead after 6 hours. What options do I have that might increase that life a little longer?

You may wanna take a look at THIS THREAD

Thank you much. I'm not sure how I've missed that thread as I've spent a good bit of time on those forums as well looking at different tweaks.

[ROM THINK TANK]---Battery Life---[WIP]

How do we make a rom with the best battery life? In this thread, we will make it.
Food for thought:
Underclocking
*#*#4636#*#* configurations (wcdma, gsm only, what is best)...}These two will help with the "mobile network" process,
lower gprsclass........................................................}that uses so much in the "battery usage" breakdown in settings
undervolting
wifi scan time
2g networks only
Battery-optimized kernel
NO Swap or Ram Hack or CompCache
ETC.
Anyone have ideas.
I will now list the rom with the best battery life (that i've ever tried)
Htcclay's Superfast 1.3.3
Please post the roms you think have best battery life.
I'm going on a vacation and will not have a charger handy at all times. What is best for me??? contributions are welcome (until we make the ultimate rom discussed in this thread.)

gee the forums are slow today... reserved

enomthers official AOSP 1.6..

i am running superbad cm51.2.3gj4 and i get around 24-30 hours on a single charge

I'm running SuperD 1.11 with SetCPU @ 384/128 and get about 4 days on a single charge. 3 days with heavy usage and 6 days without any data transfer (only sms and sometimes phone calls).
This is by far the best ROM for battery life I've used. Haven't tried Superfast 1.3.3.
Is it possible to undervolt G1s or MT3Gs?

jumped to almost every 2.1 rom out, Chromatics 3.5 being the last 1 and all of them are battery hogs. I was tired of it so decided to revert back to 1.6 roms (htc clays super csdi) and must say that Im staying here..Its much faster and the battery life nearly doubles. and also with ADW launcher, it gives you everything you need besides MT. Again battery is amazing on csdi roms. just make sure you turn off modder cpu and turbo mode in supsetup and use setcpu clocked at 128min 528max..

I agree. Battery life with 2.1 roms is terrible compared to 1.6 roms (which last up to 50% longer).
Something doesn't seem right with 2.1 roms. I hope Froyo will be better.

i really like the idea of a battery-optimized rom for g1/32b.
i also made the experience that 1.6 roms are better in terms of battery life than 2.1 based roms. they also are much faster
btw: the best 2.1 based rom for battery is speedtest 1.2

I agree that the 2.1 roms are all terrble, and that something uniform must be wrong with all of them in order to have ALL of them have such bad battery
wow that was horrible... im tired
I'm glad that many of you are interested in a battery-optimized rom. I'll be trying out SuperD today, but its use of swap is detrimental to battery life... I'll have to see.
Any other suggestions?

that's attractive... are you using ram hack or not? swap/compcache settings?

I remember some of the older 2.1 (Not CM 5 based) roms being not nearly as bad on battery life, like KingKlick's. It wasn't as fast and stable as Cyanogen's, but I remember being able to easily go through a full day and half without needing to charge (with moderate use, and an 8 hour gap of nothing for sleep). Maybe digging some of them up and doing some tests?

Hmmm, well didn't OpenEclair go up to 2.2.1, before Wes joined CyanogenMod? Do we know what the big difference is between those older roms and Cyanogen's implementation and why there's such a drastic battery (and performance) difference? I always thought it was just lack of drivers and Cyanogen did extensive work to various driver projects to get workable drivers. Would his drivers be the cause of poor battery life? I'm grasping at straws here, but that seems like one of the only things it could be to me.

No compcache/swap but with ram hack.
2.1 roms are using a lot more ram then 1.6 roms.
With 1.6 I have about 40 to 50 MB of free ram after using taskiller.
With 2.1 only 20 MB. This is just a guess but whatever is using these 20-30 MB of ram might be partially responsible for the battery drain.
If additional battery drain is the nature of Eclair (which clearly wasn't built with our "old" phones in mind) then Froyo might bring some improvement.

I've noticed the same thing. 2.2 seems to be better... but jubeh's rom quit apps in the background much quicker than the other guy who compiled from source and posted in this forum (his had no wifi tho, but i liked it better because of memory management)... i don't know what the difference was, but i liked the other guy's froyo rom better.
Back on topic, I still think that 1.6 remains the best rom for battery life.

Change Log:
-Updated Frameworks and Settings from latest Cyanogenmod Donut tree
-Proxy Settings in Wireless Settings
-WIFI in Airplane mode
-USB Debugging notification option
-5 minute screen timeout option added
-Updated Working Renice script -thanks to merlos
-Media to SD -thanks to merlos
-Exchange Work Email app fixed
-Battery percentage option in SpareParts
-Live Folder FC fixed
-Portrait / Columns bug fixed
-Remove Launcher script – This fixes the battery life.-thanks to merlos
– from terminal type remove_launcher then the one you want to remove nexus or stock
—-EXAMPLE: remove_launcher stock
-Other Crap
Maybe the claim that 1.10.02 has better battery life is because of the "Battery percentage option in SpareParts" Some people think it drains the battery. For users of 1.11 I recommend to disable it (Settings -> Spare Parts -> Battery Status Display)

I would like to add something about RAM hack... Some games don't appear as "3d" but still need that RAM. As I remember running a 3d game on a ROM with the RAM hack would drain your battery horribly fast and make the game horribly laggy. Well some games can handle the lag, but still destroy battery life.

I think the main idea about this thread/rom is to make a rom for the g1 that makes for great battery regardless, so ram hack could be an option that will be disabled for this rom.

I know what the thread's about, silly. But RAM hack has a great chance of just destroying the whole "better battery life" aspect and I don't think there's really a way around that, that's all I was trying to say.
If you do end up making a ROM with crazy good battery life, I'll definitely keep it around for vacations. I made the mistake of going on vacation with a 2.1 ROM - my phone lived for two days out of a week (and that's with charging every chance I got) so I'm all for you. =]

[Battery] Recommend widgets/apps/roms/packs/anything what could improve O3D's battery
- I found some apps what helps, similar to task killers, but they seems to be abit 'better' in some way, not sure if task killers are actually good, but I will give it a shot for a day or two to see some improvement.
- What about these performance packs, are they really improving performance, if there is such pack out, is it possible to change it to battery saving pack which will lower your performance in exchange for battery life and how long will it last longer if will made such pack?
- Custom ROMs, can they actually increase battery life without killing performance or maybe boosting performance AND battery life? and is there any good ROM out yet for LG Optimus 3D?
- Is it possible to use LG Optimus 2X rom's for LG Optimus 3D?
* TESTING:
- Battery doctor, it's task killer + battery monitor + log/graph for charging etc etc, will try it out and will see how good will it improve battery.

Software can have a great impact on battery life and custom ROMs can help without losing and sometimes even gaining preformance.
There are NO custom ROMs out for O3D, the phone is just a few weeks old, ROMs takes time, O3D will probably take even more time than usually since the 3D is new to the platform and to the once creating alternatives.
However there are things happening on the ROM side but don't ask for a ETA etc since there is no way of telling and people do it on their free time.

Nice to hear that, about performance improvement regarding to losing it.
What about other similar phone ROMs, like Optimus 2X, possible to import that in O3D just to add this 3D space seperate or maybe just make Sense 3.0 with 3D space. I'v heard Optimus 2X is same as Optimus 3D, it's just some features are in 3D, but rest seems to be same as in 2X?

Can someone please post some example of real world use versus battery life, so the people can get a feel how much the battery lasts on average.
Thinking of getting myself a O3D but i am concerned about battery life.

You won't get 24 hours out of the battery I charge mine in the morning so its full at 9 ish and by maybe 9pm it can be around 30% or less but that is best case scenario.
I think if you don't have a car or a way of charging this phone a spare battery is needed to guarantee a full day.
Would be interesting to find out if the 1900mah battery's I seen on ebay make any difference.

I'm trying juice defender right now...

No the 2X or any other phone doesn't have the same hardware, the chipset in O3D is completely new (to the smart-phone scene), some things might work but something that saves battery on the 2X might actually do the opposite to the O3D, but have no fear, in general all Android phones get better at battery handling and performance as new ROMs are released both Official and Custom, also Android itself is getting better and since this is a dual-core phone 2.4 that is said to optimize for dual-core will feel a big gain hopefully

Juice Defender and other battery logs and optimizers made it worse for me. I leave gps and wifi deactivated until i need it,screen brightness on auto. I keep mine loading over night. I leave home at 7am and am back at 6pm with 40-60% left on my battery.moderate use,some calls music email surfing. Im really happy so far!

Just need to be patient. Afterall it is a very new phone.
I am getting the 1800 battery myself. it'll give more juice to the phone. Also if no task killer is used, you will experience a much faster drain in battery. There are tons of apps opened by default. So a task killer with careful plan will gain quite a lot in power saving.

havn't seen alot improvement from battery doctor, but atm waiting on new battery to arrive, will see how long will it take on new battery and is it gona be better then stock one.
also now using juicedefender with aggresive profile, will se how will it boost my battery life

[Q] just got the Nexus S 4G. should i stick with stock?

Hey everyone, i just upgraded to a Nexus S 4G this morning from the ol samsung transform, and i was planning on applying cyanogen but then i messed with the phone a bit, did root and restored a couple of my game apps...it seems to work with very nice speed, only serious issues ive noticed are just with the signal, sensitivity of keyboard, and i havnt had time to see battery life yet..
But i was wondering, since the stock rom is so clean and fast, why are we putting on different roms like cyanogen?
More importantly, as far as kernel, whats the best kernel right now for nexus 4g? im running stock kernel, but naturally and ideally id like even more speed(not sure what id use it for, but always nice), better battery life, and better data signals..
ive been reading about overclocked kernels a little bit and such, so basically im wondering about what you guys would say to all this? should i change rom &/Or kernel? to what? why? does overclocking at 1.4ghz like these kernels say have any negative side effects? things like that.
Thanks for your response!

There are quite a lot of things that can be changed by flashing a custom ROM. Cyanogen is reported to be more responsive than stock android, and a slight improvement on battery life and performance. Also, with other ROMs like MIUI you can completely change the entire GUI basically. The lockscreen becomes changeable by one click in the themes app. I've also noticed a slight improvement in battery life/performance and responsiveness.
Also, with regards to kernels, they add extra features (like voodoo sound, BLN notifications, UV'ing, OC'ing, etc). Now if you're looking to overclock your CPU AND save on battery life then that is probably not going to happen. If you OC the CPU you'll as a result draw more battery power when it reaches it's peak. Hence why I went with the TEUV88 kernel. This kernel undervolts the CPU yet manages to give me the same performance as the stock kernel. It runs extremely nicely and the battery lasts me about 24-30 hours on moderate usage where as before I was getting around 16.
Hope this helps.
Edit:: note that both undervolting and overclocking can be dangerous for any phone. The kernel developers put their kernels through testing though to ensure they are stable enough for most people (I hope anyways). But be aware that it is possible to damage the hardware be either of these methods.

yeah im looking at more undervolting for battery life cause current performance seems great for me as of this point. but i mean cyanogenmod doesnt change much since its built on gingerbread, its just slightly more customized, but on the actual performance side, it is a slight increase? so whats the best kernel for undervolting and still getting stock performance or more? im guessing its the one u just mentioned? cause i saw a voodoo kernel or something on main dev page and itwas undervolted and OCed to 1.4 i think...idk.

Yeah you might be talking about the matr1x kernel. It ocs to 1.44 and is uved also. Plus has voodoo sound, bln and bld. Some people have issues with cm7 and some don't. I really don't like the look of miui so I can't say for it. But I use decks 1.3d with zero issues and matr1x kernel with zero issues along with heavy use 4+ hrs screen time in over 12hrs. Personally running 1.44 your phone will prolly lock up but I run 1.2 non stop no freezes or lockups or reboots. Try them and see qhich ones fit you and what you like.

I'm still on stock with mine and honestly, I don't need anything else... i get 12-15 hours of moderate use and i don't really know what lag is because i never experience it with my phone.

The above posters are correct in everyway. I mean it definitely comes down to preference. I was averaging about 13-15h on my stock kernel/rom but my phone would be basically completely dead.
I switched to TEUV88-rammstein2 (Trinity Undervolted rom). It has Voodoo sound, BLN (backlight notification), and with todays update it has touchwake mod. So as you can see my phone lasted 15h (still with 35% battery left) with 3h of screen on, and 45m of audio streaming, and lots of texting.

amazing battery.. better possible?

I'm using current venomxl Rom with elemental kernel (all default other than max 1.5ghz and flu overclock off) and getting what I feel are amazing results on battery life. On phones of the past, aosp style roms pulled better battery life, but I saw here in the forums people were getting better battery life with sense roms? Is that true? I posted a screenshot below of my battery life, sorry couldn't figure out how to get jpg link from dropbox app.

Would be nice to hear what Rom/kernel combos others are using and what kind of battery life you are getting.

Put the picture in your public folder. Right click on the picture and click copy public link, or something to that effect then paste the link in your thread.
In any case, the only things you could do to get even better battery would be to undervolt your processor and maybe underclock as well. Some phones become unstable however and while I noticed the general ui and most apps run fine with a clock speed of about 1.2ghz, some, more CPU intensive apps do lag a bit. You can also disable radios when not in use. I actually use juice defender to do this for me automatically, which is pretty handy though not everyone likes the idea of having an app do that for you.
Last but not least, if your radio signal seems low most of the time, you can try flashing different radios to give you a better signal which will, in turn, increase your battery life.
Hope this helps, maybe others have had different experiences?
I use viper and bulletproof right now ad I wanted a stock kernel with swipetowake
And this holds up damn well in terms of battery life. Never used elemental for long though so not sure if it's better or worse.
*edit* I forgot to add, you can also turn off fastboot. Your phone will take longer to power on but saves some battery life.

Such reports are often just anecdotal and very subjective. Like you, I've also seen people claim better life on AOSP or certain ROMs on various devices, but never really experienced it in any consistent or meaningful way. Battery life often has more to do with the radio and reception in your specific care, than anything. Sure, various ROMs on various devices may have some subtle difference in battery life. But unless you are very methodical and scientific about comparing them, there are just too many variables involved, and you are often just left with subjective reports and placebo effects.
Can't open your pic. But if you are satisfied with the battery life (enough to call it "amazing"), I'd just go with the ROM that has the features you like the best, and leave well enough alone.

ROM with best battery life

Hi
A friend of mine is endlessly complaining about the bad battery life on his stock nexus 5, the phone is off the charger at 7am and is all but dead at 4pm
Being a nice guy and all, I want to help him out by offering to install a ROM that optimises battery life.
Can anyone suggest a good rom for the task ?
If such a rom exists and battery life can be extended to 15 to 17hrs I might jump ship from my LG G3

None

roms have absolutely nothing to do with battery.
battery is determined by your personal use, your personal setup, apps installed, and very much the quality of your phone/data connection. there are other things that'll influence battery life slightly as well, but these are the main things that determine your battery life.

Turn off auto and set the screen brightness display to 15%!

Autobrightness isn't too bad if your ROM allows you to change the values/levels
Also, "Lux Autobrightness" is useless for saving battery on an LCD screen since the backlight is still the same brightness. on AMOLED (aka not the Nexus 5) it would help, however.

not sure I agree with you, project volta looks like a concerted effort from Google to do exactly that.

Funny. I always use Auto-brightness and get 4 hours SoT at least twice a week. Other times, I get a little over 3 hours or below.

The best battery life for me is with elementalx 1.05 kernel with a stock rom. 2 days stand by and at least 5 hours sot is the usual verdict.
But i think the problem here is how your friend uses his phone

Different ROMs do have different battery usage. Even with the same kernel. He could stick on stock with elementalx aosp kernel. Then mess around with trickster mod to suck out the most use. Only use the high power goveners when needed. Then switch back to low power for general use. Honestly, had my n5 for a month. Also had a n4 before. The n5 battery isnt much better. Biggest downside. Just doing nothing its fine, but if I play some games on the train it dies in no time.
Some ideas
Vanir
Slim
Purity
Cm11
Vanir with elementalx was good for me battery wise. But after a certain nightly I was getting alot of heat and battery drain. Im now using sabermod carbon with elementalx.

Turn Location off. It has the biggest Impact in Battery life time.

"Best" ROM.
There is no such thing as a best ROM. The question itself is ambiguous. "Best" is obviously a subjective term.
What I want from a ROM may well differ from what you want from a ROM, ergo - what is best for me could be worst for you.
If you are asking what the most popular ROMs are, or which ROMs people are using, you can see which threads stay around on the first few pages (and have the most posts) in the Android Development or Original Android Development forums. You can also see what other people are running by reading the What are you running on your Nexus 5 thread.
If you are asking which is the most stable, being a Nexus device - they're all pretty stable.
If you are asking which is best on Battery, ROMs only affect battery if they have a feature that is badly coded. You will likely be able to read about this in the ROM threads. ROMs do not impact battery life. The only impact to battery life are your apps, your settings, how you use the phone and mostly, environmental issues such as Phone Signal.
For tips about improving battery life, please read [Battery Life Help] Troubleshoot battery issues here!
"Best" Kernel
Also, please note that as above, "best" is still subjective. What we all want from a kernel is different. Again, many people have the misconception that Kernels affect battery life. Let's get this cleared up. Although Kernel devs will build in optimisations and efficiencies that will improve battery life, these are very, VERY tiny...and if 1 kernel has these optimisations, they likely all have.
People will often say "Kernel x is better than kernel y for battery life". This is actually wrong. Kernels respond to user settings. Setting up the governor to favour either battery life or performance is simple enough to do, you just have to do some learning. The reason people think Kernel x is better than y is because developers set their kernels up with their preferred governor settings. This is what we refer to as out-of-the-box settings. The out-of-the-box settings for kernel x may well produce better battery results than the out-of-the-box settings for kernel y, which favour performance. The fact is, you as the user have the ability to tune kernel x or y to perform the same, be that battery or performance - so start learning how to do this yourselves - that way, you can choose the kernel based on the FEATURES you want, and not the fictional performance benefits of one kernel over another.
Hope this helps

There is no such thing as a best ROM. The question itself is ambiguous. "Best" is obviously a subjective term.
What I want from a ROM may well differ from what you want from a ROM, ergo - what is best for me could be worst for you.
If you are asking what the most popular ROMs are, or which ROMs people are using, you can see which threads stay around on the first few pages (and have the most posts) in the Android Development or Original Android Development forums. You can also see what other people are running by reading the What are you running on your Nexus 5 thread.
If you are asking which is the most stable, being a Nexus device - they're all pretty stable.
If you are asking which is best on Battery, ROMs only affect battery if they have a feature that is badly coded. You will likely be able to read about this in the ROM threads. ROMs do not impact battery life. The only impact to battery life are your apps, your settings, how you use the phone and mostly, environmental issues such as Phone Signal.
For tips about improving battery life, please read [Battery Life Help] Troubleshoot battery issues here!
"Best" Kernel
Also, please note that as above, "best" is still subjective. What we all want from a kernel is different. Again, many people have the misconception that Kernels affect battery life. Let's get this cleared up. Although Kernel devs will build in optimisations and efficiencies that will improve battery life, these are very, VERY tiny...and if 1 kernel has these optimisations, they likely all have.
People will often say "Kernel x is better than kernel y for battery life". This is actually wrong. Kernels respond to user settings. Setting up the governor to favour either battery life or performance is simple enough to do, you just have to do some learning. The reason people think Kernel x is better than y is because developers set their kernels up with their preferred governor settings. This is what we refer to as out-of-the-box settings. The out-of-the-box settings for kernel x may well produce better battery results than the out-of-the-box settings for kernel y, which favour performance. The fact is, you as the user have the ability to tune kernel x or y to perform the same, be that battery or performance - so start learning how to do this yourselves - that way, you can choose the kernel based on the FEATURES you want, and not the fictional performance benefits of one kernel over another.

with this guy

I used about every rom and kernel.... And my battery life for me, with my lean setup and usage was always 24 hoursish total and usually over 6 hours screen time on all of them.
So no one will ever convince me that different kernels and especially different roms affect battery life any more than in the smallest ways. Definitely not enough difference to base a choice on solely.

Well said. I hope you don't mind but I've linked your well written response in a Reddit post. Users there argue daily over which ROM or kernel is best for battery life despite my best efforts.

Not at all. I'm just copying and pasting it wherever needed now.

not sure I agree with you, project volta looks like a concerted effort from Google to do exactly that.
