    First off sorry if this has been posted already but I didn't see it anywhere.
    So I just switched over to simply stunning and I love this rom however my battery life is terrible. My screen brightness is set at the dimmest it can be and the battery still drains swiftly. I am using the stock kernel with this rom. Just wondering if someone could give me some tips or let me know some set ups there using cuz I really want to stick with this rom.

    The stock kernel is clocked at 1ghz, you might need to use SetCPU to downclock it for some more battery life.

    91ludesit is correct, firstly make sure you have setcpu, and have some profiles set up. Also, how quick does it drain, what apps are you running, etc. I unplug my phone at 5:30 in the morning, and when I plug it in at nights, its usually around 40 or 50%, with about an hour and a half of web browsing, some phone calls, etc.

    Not too sure I agree with the SetCPU theory. I flashed SS4.7 the morning it dropped and tinkered with my phone all day trying to get the ROM to run right. Long story short I tried several things but had issues and had to restore my Sapphire 1.0 backup. Before I restored my battery percentage with SS4.7 was at 70%, after my restore to Sapphire it was at 90%! I thought it was a fluke and continued to use the phone to see if the percentage would drastically drop but it never did. I have never seen a battery percentage jump this much when flashing from one ROM to the next.
    Don't get me wrong, I am not here trying to bash SS4.7; I will continue to try and figure out how to get this ROM running on my phone because I think Chevy has some great features in SS4.7. I'm just saying some of us may be experiencing this while others are not. My phone ran very hot on 4.7 which is why I suspect I had poor battery.
    Just my $0.02

    You had 70% with SS, then you restored a backup to sapphire and your battery said 90%? :icon_eek: That doesn't sound normal at all

    Even though the kernel is a 1ghz kernel, it will still run to the default max, which is 550mhz. Most likely the cause of the battery drain would be an app that broke during the switch. Although one thing i recommend trying is using wiping. Some issues can be resolved this way.

    Edit: I don't know what would cause the battery issue, but like I said try wiping. With bkapps, it will be easy.

    Im running SS4.7 with 7x LV (not uLV) 1.2Ghz.
    SetCPU @ 1000 MHz max, 700 MHz min(performance setting). Just going by what App says, I dont know if its actually at this level. But my Droid has no lag/sludge.

    Also have JuiceDefender shutting off data when my screen is off. My battery is much better with SS4.7 comapred to my last ROM that I dont need to take my charger to work anymore.

    SetCPU
    Juice Defender
    Switch Widget Pro (data toggle switch for this app was the biggest battery saver)

    I've noticed this also, but not just with SS ROMs, I've noticed this with other ROMs as well. The only thing I was able to conclude in my case is I generally have my phone connected via USB while doing this and it is charging at a much faster rate while I'm switching ROMs. I come to this conclusion because the user interface is so simply for these recovery programs that they don't use much battery, resulting in a increased rate of charge.

    My battery life with SS has been better then any other roms that I have tired. I can get 14-16 hours of life out of my phone before having to plug it in. When I get home from work it is usually at 40% and that is with texting and phone calls and also facebook, twitter, my weather app updating every 2 hours and my email getting checked every hour. Also my phone is on vibrate most of the day so that uses a little more battery.

    I always got acceptable battery life from Chevy's ULV kernels. Just for kicks while I was waiting for the latest ROM, I switched to a p3droid LV kernel (1000 mhz set to 800 mhz) to give me something new to play with. My phone stays cooler (I'm now getting down to 25C for battery temp, which I never did before) and it "appears" that I'm getting more battery life. I have to say "appears" because I've not done controlled tests but my battery % is higher at the end of the day than with Chevy's 1000 mhz ULV. YMMV but you might want to try different kernels (including Chevy's ULV, LV, and MV) to see if another does the trick for you.

    I experienced the same thing oddly enought. I am getting ok batt life with ss now though and I thought nothing of it.

    I flashed ss 4.7 the first time while not charging. I had to restore to sapphire because vzw activation was down and I needed to make a call.. when I did my batt % jumped 20%.

    Yeah, I thought it was kinda strange as well :D

    This was off the charger and the increase happened.

    Thanks for verifying I am not crazy :laugh:

    I'm going to have to agree about the battery life not being so good. It drops way faster than it did in 4.4-4.5.

    I run the same amount of widgets/homescreens and get less battery life. Odd.

    Same thing happened to me. Went from about 70% to 90% when I went back to another ROM. I couldn't figure out how to get better battery life either with 4.7. I hope someone figures this out as I really like the ROM, but I gotta have decent battery life.
