[Q] 2.1 and 2.2 roms

Does 2.2 provide better battery life than a 2.1 rom + UV kernel?
Better question...for the guys who've had the 2.1 roms + undervolted kernels and are now on 2.2...which was better? I really want to know about just battery life but the more you provide the better.
Sorry if this has been posted up, I didnt really search so I expect and welcome the flaming. I will be searching after I post this though and if I can gather enough info that helps me out, I'll beg for this thread to be deleted.

Honstley, stock 2.2 gave me slightly less battery life than epic experience 2.1 with pheonix kernel and more than stock 2.1 but I'm currently running midnight and have run every bonsai rom as well and the battery life on these are amazing, I get about 14 hours on a charge and that is litening to music for 8 hours straight while I'm at work. I can't tell you aout the other dk28 roms since I've only ran bonsai and midnight but they give me great battery life and I don't think I could stand to go back to 2.1 now

Thank you thank you I knew as soon as I went back to 2.1 someone would respond >.< but its all good. 8 hours straight of music is what I like to read because thats very close to what I pull in. 2.2 has some great UI changes over 2.1 and on Bonsai I got about 14 hours on a charge as well under perfect conditions and but daily it was an avg at around 12 so I appreciate this post a lot. I've never ran 2.1 for long, as soon as I got this phone I just put on 2.2 so I never got to see what it had to offer so I guess I'll give it a go. I really just want the added battery life.

Going from noobnls 2.1 rom with different kernals, stock with noobnls kernal, now to bonsai, I say its pretty close to the same on some days 2.2 last forever that's if I'm not hands all over it playing with all the awesome 2.2 feutures which has been since last weekend once I get bored of the upgrade I say 2.2 bonsai is better

i get better battery life on dk28 than di18.

coolness. i've been back on 2.1 roms, and I haven't wanted to change back to dk28 because of battery life myself. but a lot of people are liking Bonsai, so that might be the next thing i try before official 2.2 drops.

yeah, Bonsai was really really damn good. That thing was on roids or something. I tried another 2.2 rom for today and it was just terrible...one thing I dont like is how they are all themed up >.< But I got that stock theme from that huge theme thread so its all good, but still....

The reason I like bonsai is its clean of no extra themes it apps its like the mighty rom of the epic and everything works amazing no bugs!!! I am very satisfied with it til next week when supposedly froyo official is coming

Battery life is all relative to what your are doing with your phone.
So many people like to tell everyone how they got XX hours on XXX Rom with "moderate use" or "heavy usage", etc..
It's all relative, moderate to some would be heavy to others, etc.

midNIGHT is based on Bonsai (IIRC), so I would expect them to be similar.

I wouldn't hold my breath if I were you.
The only thing I would add is that, for me, Bonsai does a wonderful job at minimizing battery use while the phone is idle (ie sleeping). If the screen is off it seems like it will last forever!
Best thing you could do is load up a Rom and try it out for a few days.
No one's phone usage is the same as yours so just try for yourself.

So far for me the best I have found ( 300+ texts 2+ hours phone calls lots of internet both on and off wifi/4g with screen on time (auto bright) averaging 7hrs a day) is CWM 3 DK28 EXT 4 viperrom 4.0.3 average 16 hours before low battery alert and Im pretty sure I have tried them all with the exception of cyanogenmod and for that I will wait till the team says its stable.
EDIT: for some reason I NEVER have a time without signal below or above 50% even if I check it 2 mins after unplug but that dosent seem to drain battery like it did on DI18 (average tw/os there was 30-40% same usage but only 8-9 hrs until phone off from dead battery)

What rom and kernel for best battery

Right now using caulkin 1.5a and stock kernel 1.1. No Los but battery drops so quickly it seems.

Caulkin 1.5a Bare Rom and Rogue Renegade kernel is giving me awesome battery life.

Stock kernel no Los and best bar life but rogue outlaw comes close.

This for me. Just make sure to calibrate.

Calkulin's and StarBurst are both nice ROMs, but StarBurst has been the most stable with best battery life for me.

Funny, this combination drained my battery quickly until I replaced Rogue with stock--now battery life is great. Rogue had worked fine before the most recent Calkulin update. If you have problems I think you need to try the available options or reflash.

Before switching to a different ROM or Kernel, I always go back to stock to make sure I have a clean starting point. This is so easy now this is available > http://forum.xda-developers.com/showthread.php?t=1351761
I am not saying this will solve every issue but its worked well for me. There really is no reason why a certain config should work fine on one device but not another.

Agreed.

I love starburst but battery life winner goes to Calks rom. V1.5a can last me all day with 50% left.

that is now incorporated into my flashing routine as well. Takes about an additional 15 minutes but well worth it in my eyes.

Yeah caulk use to be awesome. Now I'm getting bad battery drain. About 3% since turning my screen on navigating to this Page and replying back.
Going to flash stock tonight and reflash.

I can easily get a full day of heavy use when off charger with calk's rom. Which is nice to know. I might just pick up another battery to have just in case but coming from the Evo this phone is light years ahead with battery. I suggest flashing stock tar and pit file as part of your "wiping" routine.

Yeah I use to also but last two days its been relatively bad. Definitely flashing stock.

What about this one on battery life as well as signal extra...
EpicAOSPmodv2.5.1

I UV the cpu and GPU on stock EG31 kernel

after flashing starburst 1.9.5 battery life was great but then getting worse
I had great battery life after flashing starburst ROM 1.9.5 and calibrating, but after a couple of weeks battery life has become 50% worse. What could be the cause of something like this when my settings haven't been changed?
running lostKernelExp+
i installed badass battery monitor and it appears that the application "kernel" is responsible for 30% of my battery life. when battery monitor shows "kernel" is it referring to lostKernelExp+?

EL26 Kernel = Butter

Okay so I just installed the EL26 Rogue stock kernel and I feel like my phone just got sooo much smoother. Scrolling is like buttah! Coming from Rogue EL13, btw.

+1
Loving it!

no lie, still on EG30 mainly because love the scroll bounce, was rocking it with desperado OC to 200/1400, but this EL26 Rogue beats it how silky smooth it is.
as bonus VPNC Widget still works, see /dev/net/tun when connected with EL26 Rogue, hadn't expected this, thanks!!!

Great to hear. Still on the EG30 ROM, reading and doing more reading before I take the dive into EL26. But the positive reports are very encouraging!

Glad to hear this. Still holding out because some themes don't support EL26 yet.
Any noticeable difference in battery life on EL26?

I've never had large differences in battery life when on any modem or kernel with any custom ROM. To me it's all dependent on how your phone is set up and how much you use it. As long as I can make it through the day without having to charge up, I'm good. If it lasts longer than 24 hours, that's just extra benefits.
With stock ROM, my battery only lasted maybe 7-8 hours. On any custom ROM I've ran, it's usually well past that.
I'm on the Nothing but the honey theme, and that's been my fave theme out of the ones I've tried. I know for certain that one is working without issues on EL26 with Calk's rom.

I wasn't seeing smooth scroll performance with EL26 on UnNamed EL13 rom base touchwiz use.
Went back to EL13 all is perfect again.

Decad3nce of OG Epic Cyanogenmod fame explained to me how having a matching system is best due to intents and some other things that were over my head..lol. I always keep my ROM/modem/kernel matching but that's just me

ICS & battery

Is anyone else experiencing major battery drain on the latest leak of ICS? If so, what have you done to improve battery life? All I know is battery life was great on GB, and this is with heavy use, but now its really bad. I need to have my charger with me at work because it dies in about 5 hours.
Also, I noticed Facebook will not allow me to post status updates in native app, but if I have a widget, I can post from the widget with no problems. Is there a fix for this, or do I just have to wait for Facebook to be ICS compatible?
Thanks in advance.

Are you running a stock FD02 with stock kernel? Battery life seems the same as FC24 and better than FC22. It is a bit worse than GB but its not really done yet so I cant complain.
A long time ago I found facebook app to be a huge battery killer. This was on another phone and 2.2 so maybe its improved since then but I doubt it. Quite frankly if you can live without facebook all together your quality of life will improve.

does the rouge fc22 kernel gives a better battery life? im tempted to flash it and see how it works? anybody has tried it. Im on calks 1.4 rom

Modems are phone-dependent. Someone may have great speed on FC22 but someone else may not even have 3g on the same modem. You have to test yourself. I get best battery on EL29, but with my last E4GT I got better on EL26.

I have tried a few ics roms and battery life was worse than gb on most and i think that is expected. Ive been rumming venum's AnaKonda rom and i am currently at 37% after 16 hours of medium use.
Edit: fc24 modem and dazednconfused theme.

Am I the only one still using GB???

I have found that out of all the ROM's Ive tried, even the latest JB ones, that the ones with the best battery life and stability were Blazer and Calks 3.0. Those of which are on Gingerbread. So, am I the only one that thinks or agrees to this? I might not be "up to date" but my performance is damn good! =)

must be
What little extra battery life I'm not getting on FK23 & FL16 compared to GB is not worth all the extra goodies I would have to live without. For me GB is boring and the tradeoff is more than worth it.
Have you tried both the TW JB and the AOSP JB roms?

Haha, you're not the only one. After DD'ing Jellybean leaks for the past 25 days, I flashed back to my Calkulin nandroid backup for its awesome battery life. . I got the best Jellybean battery life on fl16 (3 hrs 45 mins) but it can't compare to the ~6 hrs on calkulin. I'm just gonna wait now for the ota Jellybean + source before I try it again.

Probably not the 'only' one. But in these parts XDA Developers you will certainly be in the minority.
By it's very nature these forums are for those looking for the latest greatest and bleeding edge technologies and tweaks.
The latest JB builds are awesome. Good battery, hotspot working natively (so far). Stable. Google Now natively. More responsiveness. Nicer looking and more customizable. I get about 14+ hours with fairyly heavy usage - my cell is my phone for work and home.
Yes these forums do provide some great stuff for the 'regular joe' but that's not what the forums are here for. We try to work together to get the most out of the devices as possible. That usually means functionalily and features 1st, performance 2nd and battery 3rd. I do know that there are some devs who may change those orders but that is usually the case.
I have always been amused by the 'how long does your battery last' crowd. While I think any phone should last at least a day with a good battery and reasonable usage I think it's silly to 'demand' more. It's 2012 get another battery (or external battery for emergencies) for backup, grab more chargers - I have one in all cars, home office work office and laptop bags.
Just my two cents.

Have you tried replacing your battery ? I just bought 2 new ones from Anker and my phone is getting better battery life and I'm running FL16 JB. I am delighted with the purchase and wish I had done it sooner. Here's link and read up on them as well.
Anker battery for D710
Good luck

Personally I use CM10 on my phone, but on my mate's phone, it's running Blazer's 4.1 GB sheerly because of the WiMax speeds. If I didn't love flashing the latest and greatest, I would've stuck with GB too.

From my experience, nothing beats calkulin's 2.8.1. I wanted to like more current roms, but even with underclocking, ics and jb chug the battery. People can ask or claim that your battery is bad. If the battery is bad then why can I get about double the battery life out of calkulin when compared to more recent roms? Same battery, twice the run time, practically no lag or noticeable performance hit. I was halfway through my second extended life battery during a normal shift at work with ics and jb when going home when I'd be around 20% with calkulin gb on the first battery. I'm not saying everyone else is wrong in their preferences, but to me, battery efficiency without noticeable CPU hit means everything. Other builds seem sluggish and battery hogs to me. Don't get me wrong, there's some cool features with new builds but the trade off of battery isn't worth it to me. It's a damned shame calkulin moved onto other pastures. He definitely knew his $hit when it came to tweaking rooms and I like his choices he took in his earlier builds with this phone.
I think if calkulin and bugless beast Pete got together, their rom would be damned near bulletproof. Peter Alfonzo.

Pacman ROM has amazing battery life for being JB. Plenty of customization tweaks as well, I used to only rock blazer 4.1 as well but some of my apps got updated and now require to be on ICS or JB based ROM.
