Battery life: three days sixteen hours at 25%

Yes, I've been using my phone the past few days. Andromeda Three is great.
EDIT: I was dumb and didn't notice my phone number there, could a mod remove the quoted pictures? Lol.

Sounds like its been sitting on the table

i got about 3 days on andromeda 1.2 with moderate use. if the op is a light user and turns data and wifi off when not in use i would expect about that. honestly that rom is so good on battery that i stopped using juice defender because it was only saving me a couple percent and since i could already go 2 days without thinking about it and have 25-35% battery left.

Apparently background data has been on this whole time since I hit the market icon and it went to the market automatically...

Andromeda was a great battery saver for me too, but I can't say it was THAT great lol.

I had great standby time on Andromeda but with heavy usage it was about normal. Leaving it for 8 hours with no use I would get 0-1% battery drain and that was with data and Gmail syncing. With heavy use i was able to get around 3 hours of screen use a day, sometimes a little more.

We put alot of work into refining Andromeda3.

Well I was on Andromeda when it came out. Never got 3 days.

Deep Sleeps Woes

Does anyone else have an issue with the phone NOT going into Deep Sleep after unplugging from charger? Phone deep sleeps after rebooting, but upon plugging in charger and then unplugging never sleeps again until a reboot. This isn't ROM specific and happens in all of them.

Have toy tried using better battery stats to find out what is causing the wakelock? I've had fewer issues with this phone and deep sleep than my previous i9100.

I've tried, but BBS shows me obscure names (can't recall atm). Haven't been able to track back to a specific app or what not. I'll try BBS and report back with the specific name(s).

Does it happen after a factory reset?

Take a screen shot of partial and kernel wakelocks and let us take a look, and maybe we can solve what random PID is causing your issues.

something like setcpu will tell you what frequency you are idling at, and if you are in deep sleep or not. could you install that and take a screenshot?

I've been using CPU Spy and it shows at 192Mhz most of the time after unplugging charger. After reboot it shows majority in deep sleep.
I can attach screenshot later after plugging in.

you need a custom kernel which supports changing the min freq.

Same here, Deep Sleep required reboot after unplugged. I am on Skyrocketeer with sky kernel.

[Q] Screen absolutely killing battery

Hi, so ever since ICS, or at least SCv7 (not sure if it did it stock, I switched right away), my screen has bee completely killing my battery
I still get perfectly fine life with the screen off, but it just drops right down with it on even not doing anything to heavy. Definitely a problem not normal.
Anyone have any ideas? Is this happening to anyone else?
P.S. Thanks for the new Q and A section by the way.

What are your screen settings at (levels, auto on/off, etc)? Screen is by far the biggest drain on battery. Check my Battery Guide, last Page for an app mentioned to lower brightness more than the stock settings will allow for- maybe that would help in certain instances. I haven't tried it myself, but will be doing so over the weekend, and if beneficial I will update the OP with it.
My SGS3 is the same as my A2 being that the screen gobbled up battery like crazy. So, I suppose you're not alone, at least with what I've experienced.
Not sure if any of this is helpful, but thought I'd share my thoughts...

I keep it on auto or low all the time. this is definitely a real problem, because it was nowhere near as bad on GB. now I know they fixed the cell standby issue, but I can literally see the battery go right on down when I turn it on. 3-4 hours on would kill it.

Maybe try with auto off for a while, see if you notice any difference.

Turn auto off and get a widget to adjust yourself. Read an article one time how on Android system auto brightness is more harm than good.

Looking at your battery's discharge rate graph, looks pretty normal. There's no drastic drops in battery, it's fairly linear in discharge, and even if the screen is using most of that. However, there could be other culprits. What about sync, or haptic, or any of the other things I outlined in my guide? WiFi is off, from what I saw, but might not just be the screen. Have you tried editing build prop for "deeper" deep sleep or edits to other things? I'm going to update my OP with a few more things I thought of for improving overall battery life this weekend. Maybe some of the new ones will help...

I'm sure that the display is eatin more than GB ....
i didn't see display going >50% in GB ..... now on ICS its like always >=70%
i have 2nd system as MIUI from "rdavisct" when i switch to it & come back to ICS
then my battery calibration scrambles ... i did switchin yesterday & it showed me
30% far early than expected

Same problem here..my screen draining 57%

Why don't you try the app betterbatterystats it's here in xda:
http://forum.xda-developers.com/showthread.php?p=15869868
This may help to see the real problem of the fast battery drain you said, also you can install the app rootDim from the playstore to custom your screen brightness.
I hope this helps.

Lean Kernel has amazing battery life undervolted!

Out of all the kernels I have messed with and tweaked voltage settings with, lean kernel has given me the best on JB. I did not overclock though. Here is a screenshot. Took my phone out of the charger at 9:00 AM today. It is currently 6:37 PM.

Yes really! And it is amazing. Use system tuner. Or another system tuning application. And you can do quite a bit. Very handy.

Undervolting is more for stability, yes it saves some battery but nothing drastic Imo. I usually UV if I feel the device is getting too warm while in use.

You don't need to do anything to undervolt Leankernel, it's undervolted by default.

That isn't true of the newest ones.You have to at least run the lkconfig script and tell it to allow undervolt.

Lk is not UV'd by default. You have to use Term Emu to even get the UV to stick. Guys please don't add things when u dont know what ur talking about, especially kernel related stuff. Very easy to brick a phone messing with the kernel. And for those who want to UV LK, please go to RootzWiki and use Imoseyon's chart for UV, if you UV too much you will run into problems. Its on page 142. I used his guide and LK and I easily get 24+ on a charge with 3-4 hrs screen time.
Btw LK 1.7 just released last night!

Went to page 142 but not sure I understand the slow/nominal/fast aspect. Which setting is under-volted for better battery life? System tuner shows me running the slow number settings.

Thanks
Thanks for the info. Will try it.

Do you mean the "screen time out?" Its set to 30 seconds which is the lowest setting. However, ever since i stopped a bunch of useless apps from running in the background the problem has gone away. It was also happening in class while i was connected to the crappy university network. It consistently loses and regains connection. I think that may have played a role as well

No that's not what he meant.
I am assuming you are using that CPU Master apk I slid your way. When in that app see if your profiles are on and what the min/max is set at.
I don't use profiles, tend to find they cause more problems than good. The app is constantly having to monitor and check for "conditions" to be met so it can activate the profile, using CPU to do so, which results in more battery use.
Our devices are setup with governors and/or hardware scaling which do excatly that, adjust CPU frequency based on demand.
So you have to look at it in a logical sense.
Lets say opening a certain app at 1ghz takes 5 seconds. Than say you underclock the phone to say 816MHz and than open the app. Instead off the app increasing the CPU load and the governor polls the.frequency up to 1GHz for 5 seconds and than scaling frequency back down, the governor will poll up to 816MHz and spend, lets say 10 seconds to load that app up now at the slower speed, you basically forced the CPU to spend more time at the higher frequency (816) as it's capped at that speed, so you actually made the phone sit at the higher end of the frequency pool consuming more mV in the long run than if you would have just left it at 1GHz cap and let it consume the more mV but for a much shorter period of time.
This was how it was explained to me and via my own testing the % of time spent at 816MHz was much, much more than the % of time spent at 1GHz.
Logic man, lol, logic. There will be those who argue, you just have to expirement for yourself, you'll see.
Also, don't use swap files unless you have a class 10 MicroSD card, all it does is increase read times and slows down the phone.
