[Q] Does Perseus kernel give a better battery life? - Galaxy S III Q&A, Help & Troubleshooting

I'm currently running Omega V43.2 on my phone and it works like a charm (No lag). Average battery life is 1 day and 2/3 hours on screen. I'm thinking that changing the stock kernel to Perseus may help improve my battery life but wonder if Perseus kernel really does the magic. Some advice is much needed thanks

If you leave default settings, yeah.
If you optimize it even more for battery life, then heck yeah.
If you configure it incorrectly / aggressively for performance - you may actually reduce it.

thanks maybe i should try it out.

Battery life depends on your signal strength, data transfer, running apps and usage scenario.
For my usage, 3hours is pretty good, others have far more

[Q] Good SetCPU Profiles for Eris?

I just rooted my Eris and I'm interested in overclocking. Can anyone recommend some good setcpu profiles for the Droid Eris?
Here's mine

}
The only other profile not shown is the same as "AC/full", called "USB/Full
I get about 2 days use out of a full charge, though I use the 1750 MaH battery over the (1300MaH) stock one.
Take a look at the attachment I made. Its simple, and it works well enough for me. I have the internet off a lot and am a heavy texter, so this fits.
For good battery life and good speed, try 710max 480min with 2 profiles. 480/245 when temp gets 40-43° and 480/245 when screen is off. Just my opinion. Works good for me.
Keep in mind the higher you overclock the more it will drain your battery. NEVER check set on boot till you have found a speed that is stable or your device could freeze on boot.

Hey guys this is what happens to my phone quite often is it even normal? Im using androidmeda rom and got kg1 baseband. Thx for comments and possible solutions in the mean of telling me that if u use the same rom which basedeband u use

No its not normal. It should gradually creep down not that steep drop. KI8 battery life is great... Among the other benefits. Someone with more knowledge may be able to explain whats causing that sudden drop. May be a faulty battery.

Man that is savage battery drain. Try something like smaberg's KI8 Rom with siyah kernel, I'm getting amazing battery life with that combination. Siyah also has some good advice on improving battery life.
Sent from my GT-I9100 using Tapatalk
Did you wipe your battery stats when flashing the ROM? If not, boot to CWM, wipe battery stats, charge to 100% and then drain that battery.
Goin to try that battery reset.
UPDATE: So I did battery reset but the phone has gone crazy. It suddenly started to automaticly switch to flight mode when I turn the screen on

Battery life w/ CM7 (Pics inside).

Whats your guys battery life like? Considering its alpha and all, its pretty great battery life. Figured i'd share my usage and see how it compares w/ some of you fellow CM7'ers
Btw, this is NOT overclocked.

Not too bad, as you can see, still had 17% left, but i normally dont like my battery to even hit 25%.
5 plus hours screen on isn't bad.... But I can't wait to see what it can do after they work on the power more. It is showing promise.

exactly my point. shows great promise on just alpha. curious what others are getting as well.
About the same.. I was using my TP pretty heavily for 5 hours with live wallpapers (koi - from the videos) and still had 37% battery left. Very happy with this "Alpha" build, can't wait to see what they improve.
Yeah, I've experienced solid battery life considering. Quite impressed.

Pretty good results there. I haven't installed CM yet, but I reckon I get about 8 or 9 hours of screen on time with WebOS, so it looks like CM is in the right ballpark.

[Q] Bad battery life

Hello, 3 days ago I've installed CM10.1 nightly build from 2013-07-25 on my friend's Galaxy S III (international), now his battery life is really bad and he's complaining on me, any way I can improve the battery life?
Here goes a screenshot (as you can see, he wasn't even using the phone when the battery just dropped 50%):

Cyanogen mod roms are known to drain battery much faster than touchwiz.so you cant really expect the battery life to be the same as on stock or stock based roms. you may improve the battery life by using an app called Greenify. it hibernates apps so that they will not run in the backround. this can help considerably. also make sure to turn off gps , bluetooth, wifi. and mobile data when not in use.
well first tell your "friend" that thats how things are in AOSPs. Secondly use differrent kernels and proper setting to get max battery (tutorials are available) plus greenify apps you do not use. And the usual killers as GPS/WiFi/NFC/3G use only when needed or turn them off..
Something is extremely wrong there. Get a normal usage BBS dump and post it here. Also take screenshots of the BBS pages.
Also post a screenshot of your battery stats page (one that shows which apps drain battery).

What ROM do you use? I recomend you use shostock3 v4, with jeboo kernel for me this rom and this kernel are the best combination to save battery.
Sent from my SGH-I777 using xda app-developers app
Before changing rom's, you need to install Better Battery Stats and find out exactly what's draining so much. Chances are if it's a rouge app and you inadvertently re install it on a new rom, you'll continue to have the same issues. Best to find the current cause before taking drastic measures.
Mine did this. Media sever was running wild. Check if that is the cause.

i was using shostock3 v4 itself with AJK kernel. flashed jeboo kernel and it turned out fine. BTW no apps was eating battery..looked like kernel problem to me...its SOLVED for now. thx guys
