[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?

i remember gamercore tweeted about openeclair 1.1 being really good, and i tried it, and it was quite good, but the rom sucked and it was hardly comparable to donut.

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.

v 1.11 release date : 2010 04 29
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. =]

bam_dmux_wavelock/spotify

Hi all,
Currently running CM10.0 (stable) on my One XL. When checking wakelocks after flashing, a process named "bam_dmux_wavelock" appeared to be running for hours at a time. After some poking, I also discovered that Spotify running in the background only consumed 700mb of data over 3 days. After disabling background data for Spotify, the wakelock (and battery drain) reduced dramatically. Disabling background data across the device reduced that wakelock to almost zero.
Currently getting 2 days of use on CM10 and 2-3 hours of screen time, with ondemand governor; 192 min; 920 (I think?) max. No lag or performance hit for day-to-day tasks.
Might have to do a cleanwipe and reinstall rom to get rid of the rest of the wakelocks.

Should be in q&a

i dont think this is q&a. just informing us of how he extended his battery life. good job exygenysys on getting a long battery life setup.

See, this is why I love sense and will NEVER use CM10. Reliability.
When building the One Series, HTC's engineers set out to address the biggest complaint from customers: Battery life. From their blog:
For the HTC One, we researched all layers in the phone; from the chipset, networking, display, operating system and preloaded applications – all with the goal of making the most efficient use of both power and data consumption. And our testing has shown significant performance improvements

HTC's version of multi-tasking that everyone loves to hate for no reason, gives you just that. Because many developers don't know how to properly code for battery life and data usage, someone has to do something about it or else we, the customers, are the ones who end up suffering. Android saves apps in their original state, so who cares if they are really running in the background or not? The experience is the exact same, you go back to an app, and it picks up right where you left off.
I have noticed spotify AND many many other apps taking cpu, wakelocks, and using data.. But it just doesn't happen in a sense rom because they get truly suspended in the background, and apps that really need to work in the background to be useful are in my experience , not affected.
TL;DR: Use a Sense Rom and worry less about battery and data.

OnePlus One CM11s VS CM12.1+ AK Kernel

Hello. So I am currently running an OPO on 5.1.1 with AK kernel and I get a solid 5:30 SoT with lots of restrictions (CPU frequency). My device is rooted with TWRP installed. I ask, is it worth reverting back to CM11 on 4.4.4? I'm looking for features and battery life mainly. I might change themes and kernels. But only on CyanogenMod ROM. If CM11s is the way to go, may a good kernel be recommended to go with it? Thanks for the help.

Well at this point 11S is pretty outdated, with CM13 already being out. CMOS12 is pretty good but getting a different CM12 or CM13 based ROM is best way to go in my eyes. I have tried going back to KK just to see what it is like and I couldn't use it because I had gotten used to how Lollipop and Marshmallow are. Also I don't think the increase in battery life is worth the loss of features with CM11S.

You should stay on cm12.1 and play with your kernel setting little bit!

I'd say give MahdiROM 2.9 a shot. It's CM11 and gives me great battery life, as well as being packed full of features. Even ran tests with play services forcing my phone to stay awake 100% of the time and can still push 5-7 hours SoT depending on usage. 7+ with that fixed up. ZaneZam's boeffla kernel builds for it work extremely well and I can honestly say I prefer it for CM11 even though I'm an avid AK user.

What about Boeffla Kernel? Is it better than AK?

There is no better or best kernel. There is just a kernel that fits your preferences.

I can only say that at least with my personal usage, the battery life did not change a bit going from kitkat, over lollipop, to marshmallow.
6h SOT is the bare minimum I get on regular usage no matter what. I've seen 8h SOT on K, L and M.
Always CM11/12/12.1/13 with stock kernel and stock settings, no undervolting, underclocking, Greenify or other bull**** apps. Also I don't use apps which are known for drain like facebook.
Seeing threads like this, I often think that users drain the most battery by constantly looking for tweaks and updates to reduce battery consumption.
Alibi screenshots from an early unofficial cm13 build:
There is almost no drain over night, same on data only.

Maybe your device got powerful battery and your app list isn't huge, otherwise most people struggle to get 6 hr sot on L & M. ?

Is crDroid the best actual ROM for hammerdeadcaf?

Base CAF: Smooth and 3h Buttlife
Base non CAF: A little buggie n 2 1/2 hours but snapchat (and SafetyNet required apps, i dont use any so its a random feature for me)
CrdroidCAF: Smooth, all the features i want, the same exactly smoothest from 6.0 and doze v2, almost no bug except putting it at secondary, will crash sysui whem tap dev opt) and 3-3.5h buttlife with the same social usage as other roms.
AnymoddedAOSP: a bit laggie n butt hours = 1.5 or 2, terrible.
so with my 2013 im getting 30-50% more than noncaf, letting me use my phone completely fast EDIT: with tons of features

Depend on usage, Slim7 has best battery so far.

What is the good Custom ROM and kernel for 5+ SOT?

I used default stock ROM (6.0.1), RR (7.1.1), CM 12.1 (5.1.1) with squid kernel but still my battery don't get even 3 hrs SOT with greenify also. I mostly use it for facebook and whatsapp only. I cant afford a new phone due to this. Plz help me. TIA.

No rom will give you that much of a increase, stock is the best battery in general but there is no way any tweaking will increase that significantly.
Sounds like you need to replace the battery...

That maybe your opinion, but I disagree... Facebook Lite with it's built in Messenger is essentially a specially written browser, uses far less memory than Chrome, removes ads from videos (in general there are less ads throughout) plus you can still get push notifications. I have been using it for months.
If I am "completely wrong" give me some proof. In fact, although the regular Facebook is not the best, it is hardly "mother of all battery sucker apps". It is a space and data hog, but it doesn't use battery any more than REAL hogs like Snapchat, Netflix, Amazon Shopping, SoundCloud, or Outlook, in fact if you do some testing it has less effect on battery than you likely think (granted 2-3 years ago this was different, FB used to be one of the worst offenders).
Regardless, the OP was looking for an app to increase SOT... unless you can lower the battery usage of the display, you are not going to see increases in the magnitude the OP is looking for, from 3 hours to 5 hours, or a 66% increase in SOT. No app change or ROM is going to make a change even close to that.

3 hours SOT with greenify is a little off. you need to watch for wakelocks. better battery stats or wakelock detector can be useful to you. and also, if you have greenified the apps that you use the most, it will reopen those apps everytime you open the app, that could do more harm than good. you can try shallow hibernation, or just install naptime and tweak the doze parameters using GeraldRudi's method and quit greenify for some days just to see if this improves.
Then again, your battery could be the culprit, that's always a possibility
about ROM's, every ROM has it's merits, but Motorola really knows how to optimize their ROM, so for now, I think stock ROM gives the best battery life, even if that is marginally better than custom ROMs.
Kernels: Stock moto kernel is very efficient, but you might get a little bit more battery life with squid kernel, it has a great governor that relies on voting mechanism, plus it's just perfectly undervolted to get you some extra battery. probably a 15-20% difference than the stock one.

1) Use AOSP-CAF based ROM like Tesla.
2) Flash squid or Firekernel
3) Reduce the Max Freq to 1152Mhz and Min to 200Mhz
4) Use IntelliPlug Hotplug (Turn off Touch Boost and set Screen off frequency to 400Mhz)
5) Install Force Doze app and add Facebook, WhatsApp and other Battery consuming app to blacklist (Remember you will not get notifications from those app if screen is off).
6) Don't charge too quickly, always charge to 100% and plug when it discharged to below 10% (Recommended to charge at night).
It will improve your overall battery backup and somehow SOT.
At last i am totally agree with @acejavelin Facebook Lite app is made for low memory devices so it consume less memory and also less Battery. Also it's fast and have almost every features.

The real problem here is the device is going on 2, maybe 3 years old... the battery is at it's limit and will need to be changed to get really good SOTs.
My Moto G 2015 used to get 5+ hours SOT easy... not it's barely 3.5... and this is a backup device, it has NOTHING installed in it at all but it was used regularly for 18 months. The battery is just not what it used to be and if I am going to continue to use it as a alternate device I will need to replace the battery. Like it or not, these devices were not designed for more than 2 years of service.

downclocking the cpu is kind of redundant and saves less power than what it takes. the reason why for some users min-max is a battery saving governor. Besides, the performence hit is greater than the battery gained which is not at all more than 2% probably.
you should not fully charge your battery. you can, but the best practice is to charge upto 80%. And anything bellow 25% is not good.
the issue is either wakelock or dying battery, no tweak is going to save him if the underlying issue is not fixed, moreover, doze is the most sophisticated solution to save battery till now, downclocking, hotplugs these are pointless unless one's usage is known to us. I'd suggest to have doze editor if you must have a doze interface.

You can use aosp caf osprey by Ahmed hady...it will give 6 hrs plus sot from moderate to normal use..
