i am planning to flash an aosp rom on my GSM evo(s-off,unlocked).what do you suggest.ia have tested this one (http://forum.xda-developers.com/showthread.php?t=1551746) but battery is the worst ever.barely 4 hours of using.
i would love to see your suggestions for a ROM with good battery and camera working(2d,i don't really care about 3d),also jelly bean would be better than ics but ics it's ok too!.
thanks!
As a rule of thumb sense roms tend to have better battery life and aosp roms lack that. However there are a number of ways to help save juice on your phone. Having your phone CPU governors behave in a way that saves battery power when your screen is off. Don't overclock your cpu. Smartass governor is a great balance between battery and performance. Disabling apps that misbehave. If both CPUs are online, you can force the other offline when not in use or screen off. Not having certain features running in the background like auto sync, GPS and Bluetooth. And of course there's always that extended battery.

So guys, what are your experiences with different rom's and kernels considering battery life? Which one broke the record?
Stocklite works very well.
For how long?
On 2G/3G, with gps and wi-fi on or off?
Indian stock its amazing best battery life and performance

I usually keep 3G on, gps and wifi off, and my cpu speeds set to 480 max, 245 min. brightness slightly turned up, no animations. Lasts pretty much the entire day with casual texting, phone calls and browsing facepunch
There is no term like "BEST" battery saver in custom ROM department. My configuration is in my signature. Gives me good battery backup. However, I am missing the stability of stock. But, I also hate the fact that S2E doesn't work on stock.
Battery depends on how much usage you give your phone. I follow what I posted on my signature and I get good battery life on any rom I use. As much "optimized" battery life might be on a rom or kernel, it won't matter. 1350mAh will only last as much as you use it.
I was wondering if any of you people could be kind enough to give me some more battery tips for my new SGS3.
I'm getting around 4-5% / hour battery drain on standby. I have 2 GMail accounts on sync.
Here's what I've done:
-> Removed Kik Messenger because it was commandeering an outrageous amount of Wakelock Time (about 5-11% of Wakelock Time in 4-7 hours).
-> Installed Omega v5.0 (latest).
-> Still on Stock Kernel
-> Changed my WiFi Policy to "Only when Plugged in"
Turn off automatic synchronizatikn for fcbk email or other accounts.

What does Facebook sync anyway? I always thought it was just once to get the contact pictures. I will disable it now
I've been using Foxhound and Siyah kernel, super combo. I can honestly say it's the best performance/battery life on any android device I've used, 6+ hours of screen on consistently - wifi/gps on, 3gmails autosyncing, autobrightness, 1hr>calls, 50+texts, light browsing, redditt, Google Music... Battery life is so subjective though depending on your apps, usage, cell signal, etc.
Experiment! All things being equal, in my experience its the kernels that make the biggest difference in significant battery life improvements, with the exception of stock roms vs. AOSP/AOKP, battery life doesn't differ very much minus bloatware in the various roms. And if you're a flashaholic like me you'll actually have to wait a few charge cycles to get an accurate representation of battery performance for your phone.

Thanks for the big post! ^v^. I am going to flash the SiyahKernel. But after turning Facebook Sync and the Wifi Policy (which I found out about today).
My battery is at 93% at 2h 01m 05s (also my battery goes down to 99% as soon as I take it off the charger). So thats 6% in 2 hours which is 3% / hour ! Getting there ^^
Apparently going to 99% immediatelly after the charger is normal for Samsung devices. So I wouldn't count that as reduction.
I dont use aftermarket kernels and roms, I have disabled a few stock programs I do not use and get a very decent battery with the 2x battery saver. I had already ordered a secondary battery which is on its way actually as well, so ill be covered from there on
sent with SGS3

99% right off the charger is a feature .
Undervolting is an option as well.

Oh my! Great feature! Do you know of a guide on how to do that, or is that just a fancy term for "underclocking" ^v^
As I am still on stock kernel I am obviously still on stock speeds but I'm going to flash SiyahKernel after I finish uploading photos of my A77

I don't think there are any OC/UV guides in the SGS3 forums but you could search XDA to acquaint yourself, there many writeups on the subject. Make sure have ADB and are familiar with it before so you can recover if necessary from any mishaps. Every processor has a different tolerance to OC/UV so there isn't a tried and true method of implementing it you just have to use trial and error.
I won't get in to it too much but undervolting and underclocking are related but different. Undervolting effectively ask the processor to run with less power from the battery at a specific clock speed or frequency. Underclocking would be reducing the overall frequency of the processor depending on the load. They can be used independently or together.

Ah thanks a-lot. Would creating a profile to limit the CPU to 300 MHz MAX during screen off save battery also?
I have SetCPU installed and have flashed to SiyahKernel now but haven't fiddled with it yet.

Download extweaks from the market instead to configure Siyah. Extweaks hasn't been optimized for the SGS3 yet but it works better than SetCPU with Siyah, it also has descriptions of what each setting does.
If you aren't a gamer you could even toggle two of the cores off, definitely will increase your battery without much if any performance hit in real usage.
Plenty of focus on all ROMs have been performance and battery life has not been so good. Request a ROM that focuses on battery life, for those that are away from a charger during a 14 hr. work day.

Have you thought about purchasing an extended battery ?
Or
Simply limit your processor, brightness, radio connectivity, and use am android firewall to limit which apps can and can't use data/WiFi. Also ensure you have good settings in your task manager

I get 2-3 days out of my 2400mAh-battery, using MIUI and the forbidden kernel.
I can't complain at all about battery life.
Everything runs silky smooth at 192/1180mHz - xondemand
A little undervolting and a little gpu underclock.
I think poor battery life is more "user error" than something to call dev attention for.
There are plenty of guides on how to maximize battery life on the web and on xda.
2 tips from me, because many guides get it wrong or fail to mention:
- This app lets you schedule autosync. With some care and thought when setting it up, you can be always up to date without your phone snycing all the time. If you need to be in second-precise sync-though, it's not for you.
- Wifi off @ screen off is a myth. I have set my wifi to be on all time for months now and haven't noticed any decrease in battery life. If anything, it's better now.
I use mwakious, forbidden kernel at 1512 mhz and an anker 1900mah battery and get about 19-24 hours no problem
Try using Juice Defender too
I've also noticed keeping wifi connected all day is drastically less harsh on the battery than 3g.
I get awesome battery life with mentioned banned kernel and meanrom. I just switched to another rom and not sure about battery life there yet or i'd share
I have been using MeanRom and MikVirgin off and on. I like MikVirgin alot better, and want to use it full time, but the battery life is terrible. MeanRom makes my battery last at least twice as long, but I get worse reception. I read somewhere that the great battery life has something to do with turning off one of the cores while the screen is off. I'm not an expert, but i think that is a kernel issue.
Is there a kernel that I can use with MikVirgin that will give me battery life similar to MeanRom?
That's a relatively hard question to say which kernel gives good battery life. Because no one kernel by itself can save more battery life than the other. Some do handle the tasks and compliment the CPU better than others. It all boils down to how your kernel is set up, what governor you use when your screen is on. What frequencies on and off, overclocking the CPU drains battery quickly. Having both cores online and one off when screen off. What I/o scheduler in combimation with a governor. It really depends on how you use or phone to best suit your needs, not one combination is best. While maintaining good battery is a must sometimes you end up sacrificing from performance and your phone suffers with lags. From these experiences I have found that the cool kernel and the forbidden kernel give good balance and stability in most sense roms. Along with meanrom and common sense. Those two roms I have found to give good bettery life. You just got to experiment. While one combimation of Rom, and kernel work for one persons EVO may not be the same on another persons.
I am switching to the Mi Pad 4 from another device which had much better battery life (I had an extended battery case which I can't buy for this one). I'm finding the transition difficult and I'm wondering if there are any custom ROMs that have extreme/ultra battery saving modes like some of the OEMs put on their devices. In general, they get rid of any optional/unnecessary graphical 'prettiness', limit the CPU, and sometimes restrict you to a more limit set of apps (either predefined or ones that you choose to remain active). I've just now tried a few different ones but apart from a light general battery saving mode that doesn't do a whole lot, none have this option. A recommendation for such a ROM to try would be great. Thank you!
Interested in this as well, mainly just for custom ROMs that are very stable and great on battery life. ATM, my MiPad4 is draining at about 800 ~ 1000 mA. I'm using a custom ROM created by ProtoDeVNan0 since 2019 and there hasn't been any updates for a long time. I'm considering switching to a new ROM, but from what I can see so far, a lot of them have bugs.
