[Q] Battery life

Two days ago I installed Cyanogenmod SDSL4 on my GT540.
I knew that such ROM would drain more battery than stock ROMs, yet it's draining too much battery, a lot more than I was expecting: with stock ROMs my device would stay alive for more than 3 days without a recharge, while with this ROM it went off during both the nights passed since the installation!
Is it normal that with this mod battery life went down to ~30% of stock ROM?
I'd like to flash my device again with a ROM that drains less battery, what do you suggest? Would it be possible to quantify the average battery life for the different ROMs?
Also, from a technical point of view, why are some ROMs draining battery so much more quickly than others?

- it is normal that custom roms eat a lot more battery
-> you could try to calibrate the battery (app on market) might give you some extra life
- the most batteryfriendly is definitely 2.1 ROM (stock or modded, eg Eleganceswift) then 2.2 (very good ROM: utopia or superfastfroyo)
2.3.x is well known for the battery problems (on every ROM)
quantification ? well :
2.1 100 % "batterypoints" ~ 3 days
2.2 66 % "batterypoints" ~ 2 days
2.3 33 % "batterypoints" ~ 1 day only
- technical view : i think there are many facts but mostly the features of 2.2/2.3

Thanks for the answer.
I like this ROM, but it's not worth to me if the battery lasts this short.
I'll move back to 2.1 for now, but am planning to try 2.2 soon.
Looking at some 2.1 ROM posts I had the impression that they are better in everything with respect to the custom ROM (they say custom ROMs drain less battery, are more stable and have a few fixes). Is that true?
I want a 2.1 ROM with fastboot mode enabled (but I guses all of them have fastboot already).
Other than that I'm not sure about the differences between the several 2.1 custom ROMs: which one would you guys suggest (and why)?

Quarx black would be I think the Best. Modded kernel and theme
i dont think there is a post for this rom so i am uploading the rom and posting the link here
i will say that 2.2 and up is better then 2.1 but for battery life yes its best all newer phones like the htc sensation or galaxy sII can hold more then a full day
quarx black link:

Thanks for the suggestion, and sorry for my delay.
Could find a link to Quarx's official thread (it's in russian, but browser's translator is doing a great job) on the ROMs thread.
Is the version linked on that site newer than yours?
And how big does my system partition need to be?
System 250MB and data 134MB like with the stock ROM?
EDIT: Could answer myself to the latest question: here they say a 150MB partition for system is enough for Quarx.

Which custom ROM gives the best battery Life...!!!?!!!

First of all thanks to all developers who are providing us such an awesome custom roms for lenovo k50 series. I appreciate their hard work.

Hi all, in my case, i try many roms.

I hope to see your e periences too.

Is over heating issue on custom ROMs is directly related with Battery Life ? Because I noticed that those custom ROMs which have over heating issue , drained battery faster.......!

I used almost every custom ROMs except MIUI ROMs(I honestly don't like the UI) , which are being posted on XDA as well as on needrom..!! Out of which I made a list of few Stable ROMs as given below:
1) BLEND ROM (Stable, Battery drain fast, Heating issue)
2)Official VIBEUI_V3.5_1629_7.155.1_DEV_K50-T5 (Stable, Battery life ok)
3)XUI MM 6.0 (Stable, Battery drain fast, Over heating issue)
4)AOSP PURE St 1.5 (Stable, Battery drain fast, Heating issue)
5)Ghost Glitch v6 (Stable, Good battery life, NO heating issue, Except so many useless Apps)
6)VIBE PURE St 1 (Stable, Heating issue, Battery life ok, VR support)
7)Androium VUI K3N (Stable, NO heating issue, Battery life ok, OTA support, VR support)
8)Paranoid Android V3 Final Version (Stable as compared with other CM based ROMs, Heating issue, Battery drain fast)
9)UNOFFICIAL CyanogenMod 12.1 Final (Stable, Battery life ok, Touch sensitivity Issue)
10)Resurrection Remix (Stable, Battery drain fast, Heating issue)
11)BLISSPOP UNOFFICIAL (Stable, Heating issue, Battery drain fast)
I also flash so many CM based ROMs like CM 13, AICP 10, AICP 11 etc. on my device, but there are so many bugs in it .
We don't know when we get the BEST Stable ROMs..!! But, I definitely request the BLEND ROM developer "Indian Tigers" please give us a new update on BLEND ROM. And one more thing guys - ANTUTU Benchmark scores are useless. There is no need to overclock the CPUs, in daily usage basis we expect stable, good battery life and new added features in our devices.

Custom version of s427 is pretty much good by fran123 on needrom.. I'm using his rom and its stable and battery life is ok..

For me best Battery life is Androium VUI 1 (OTA AIUM 1,2)
Just charging battery takes over 6 hours of.

and here:
http://www.needrom.com/download/androium-vui-k3n/

I have found the stable Cyanogenmod 12.1 ST5 ROM to be quite good.

Guys, I am using this ROM "http://www.needrom.com/download/paranoid-android-v3-final-version/" from needrom and applying this patch from "http://forum.xda-developers.com/k3-note/development/patch-lagfix-rom-t3466057" developed By sandeep.sethi. I am using this ROM around two & a half weeks. I must say this the best and stable ROM available on cyanogenmod base. Heating issue was solved by applying this patch as well as battery life increases. Thanks a lot for providing us such a valuable patch. This patch saves so many ROMs life and increase the performance level......!!!!!

I tested many roms regarding the battery life in the past and reported all the results in the Index Thread with screens and all. One of the very best for battery is SudaMod and I'm still using it.

Actually there is no rom right now give such that...the android itself make battery life short.
Google has develope new android 7 nougat & state that it has improve the battery consuming power for smartphone

I'm very happy with the italian rom MM 6.0 1621 (and 1609 with google dialer) from the italian developer Cuoco92. It has a very good battery life, plus other little features like the touch on status bar clock to shut off the display and so on.
The only thing that I don't like is the showing of numbers on dialer and dial list. I resolved installing Truecaller.
The rom is in the Cuoco92's channel at androidfilehost.

EMUI vs CM 13

I want to hear the experiences you guys have with emui vs cm13.
At some points i always wonder if i should flash back to emui because of a few bugs and problems so i wanna hear a few experiences to see what you guys think about it.
- generally speaking i would love to hear what you like in comparision to the other
- how's your battery life, usage experience, how you think about the current bugs, etc.
- are you thinking to change rom to emui or to cm13 and why?

cm gives a more stock experience compared to emui, better battery life. unless youre going to update to emui 5, cm is better

With papsi ROM everything is fine by battery life is miserable with an outdoor brightness and mobile data on (only few hours).
Speedo; very descent battery life , zooming is fine but video recording is not, still buggy and finger print not working
Till now I think the best available firmware is stock but if speedo_thc managed to get his ROM as functioning as papsi's he will be the best daily driver for me.

papsi's isn't that bad on battery life for me. i get two days usage with constant bt connections and a few messengers push. you will have monitor wakelocks and stuff to optimize as much as possible though.
i am using
- amplify (no donate)
- greenify with xposed + root
but have 3 messengers, email and android wear on push at all times.

Cm notifications fixed emui not

cm's will always break after few months of heavy using, stock wont. sure cm has more customizeable tweaks and in some cases better battery life (never in my cases). evey device i have tried cm it always starts randomly rebooting, lagging and eats battery like hell(hahe had this issue with multiple devices). i prefer stock base and then rethemed to whatever you choose.

Currently, no custom rom is stable enough for daily use. I still love the EMUI camera and the finger print gestures. I will stick with EMUI 4 for now hopefully until custom roms are more stable and fully functional.

I've used papsi's rom for a few weeks as a daily. So far the only downside to me, is the battery life compared to stock emui.

Papsi's cm13 is better than stock EMUI on almost every points except the battery. I'm using his rom since he published it and it's pretty stable but the battery life can be a deal breaker. Some optimization would make the rom great for daily usage.

I agree with you, i would use his rom but the problems with the camera and battery life and the phone getting too hot when playing games or watching videos is what keeps me on EMUI since i never had issues with notifications.

G900F most battery friendly rom?

I dont care much about saving space, and from my experience debloating doesn't do much to the battery life. I'd like a stable rom with possibility of black theme. All I care about is decent speed and screen on time. As for kernel I'm open for anything. SmallWiz V8 UX seemed like a good fit, but fingerprint doesnt work and theming is not possible.
Maybe stock rom with assertive display, phoenix kernel and modded theme is enough?

If you want black/dark themes, you are limiting the possibilities by going with stock-based ROM. Resurrection Remix N may be a good candidate because it has theming support, good battery life (although less than stock) and is quite stable for daily use.
If you only care about battery life (and can give up some theming), (generic unbranded) stock official ROM is your best bet.

Surprised to hear that stock is supposed to be best. I had xXx rom before, but when I got my phone back from repair with stock rom and new battery there's less juice than on xXx. Regarding black theme, it's just about battery life, not about fancy theme.

Stock usually performs the best in SOT tests because it has better frequency scaling and is able to use samsung closed-source drivers that is unavailable to AOSP ROMs. Most problems with battery life arise from either carrier bloat, or the apps installed by the user. There may also be a chance where something else is the cause but only in rare-cases. Usually a factory reset can fix all of these problems, however it may not work for all.
With that last line in the original post, it is often thought that using stock kernel will yield the best battery and stability. It has been discussed throughly about the battery impact a custom kernel places, and whether or not undervolting makes a difference (where it usually will yield almost none).

Any rom that supports the Boeffla-Kernel

i'm using popwiz 5.1
give it a shot

Best Custom rom

Hello guys
I've just received my OP5 and I was wondering which rom + kernel combinaison to install for the best battery life / performance combo
Thank you in advance

Try them and see how you get on, other members here usage will likely be very different to your own and also consider signal quality, what apps you use will also be different.

I've tried a bunch, some Oxygen based (the stock OS) and other AOSP based. Both offer great battery life (7-10 hours SOT) and stability, so it really comes down to the features you are looking for

google it, you will find the rom
