I'm Getting Great Battery Life!

I installed OMGB-6 when it was released. Then flashed invisiblek #21 kernel and the new market. Since I last charged it, I've talked on it for about an hour, used the web-browser (Skyfire) fairly moderately, sent a few emails (Gmail), and spent a total of about an hour of GPS through the application WAZE. I'm left at 22% battery left after about 22 hours of use.
I've been fairly lazy with regards to changing the screen brightness, so it's been on about 50% brightness. I've left sync and gps on during the whole time.
I've been using Watchdog as a smart task manager. I have SetCPU installed, but I haven't used it at all.
Here are some pics:

I have not installed the kernel but my battery life is terrible. I barely have any apps and I do not use my phone a lot. I love the rom (favorite by far). Should I try to install the kernel.

Can't hurt, just nandroid first, or have a spare kernel handy.

I chewed through my battery in about 10 hrs today with the same kernel.
Guess I use mine a lot more. I've also got 26 hrs out if it when I barely use it.
Don't think you get great battery life when you don't use it much.
I'm in CM 6.1 but that wont really matter.

True, I haven't been using it all that much. But compared to other ROM's I've used, this get much better battery. Everything else I've tried out got me a max of ~12 hours even on idle the whole time.
Definitely try to install the kernel. Can't hurt! Just make sure you always have a nandroid backup available.

Stock Battery?

50% Brightness?!?!?! Wow....battery life is not worth looking at a dull screen. 100% all the way for me...im using 1800mah from ChiChitech that I got for $20. Seems to help enough.
I'm also running a Gingerbread ROM (Evervolv a17) but can't tell what difference it's making on battery.

Hydra 1.13 overclock kernel, stock ROM, stock battery, auto-brightness. I'm currently at 20% battery after 2.5 days. Light usage over the weekend, but there is an hour and a half of talk time in there and a half hour of reading.
The trick to DI battery life is keeping the data network usage/standby under control. If you're trying to send/receive data with no signal, the phone will burn through its battery in 4 hours and I've used 20% in 15 minutes trying to book a flight on a low signal connection.
Realizing this took me a few months since I live in NYC and as such, go through a lot of signal shadows. Some days my phone would be at 50% battery after 12 hours, other times it'd be dead after 6. I now realize that the short days were caused by sync services trying to run when I was in a shadow. You can diagnose this for yourself by going to the cell standby section of the battery usage. If you're over 10% or so without a signal, you have this problem.
You can handle this manually by holding down the power (on the stock rom) and enabling/disabling mobile network. This is a pain in the ass.
I handle this with some simple Locale rules along with the Mobile Signal and Mobile Data plugins. The first is to shut off the data when there's no signal. The second is to shut off the data at work where I'm usually but not always on a wireless network. The third is to shut down the data during my normal sleep hours and airplane mode if I'm at home.
These easily got me to 36 hours so I grabbed an undervolt kernel, which gets me to 2 days of regular use. Daily I do about 15m of talk, 40m reading news/email on the subway, and another 30 mins browsing/messaging/misc. My monthly data use is ~350MB.

While it is likely true that the OP and others have good battery life under their specific use conditions, battery life in general on smart phones is mediocre to poor at best. I have friends with various different models of smartphone (including iphone) and across the board battery life is not good. The exception is blackberry, but I don't consider those competitive from a tech and feature standpoint. Obviously different people are going to have different opinions and experiences based on the various factors that influence battery longevity.
The solution is to stop worrying about it, get a spare or two or three and pop in a new battery when one dies. This imo is one of the best things about the Dinc and Android phones in general. Just my 2c.

I had the exact same problem on EE03. Couldn't get 8 hours using wifi and the phone in sleep and I live near a tower (never have less than full bars).
Suppose this explains the delay and EF10.

that sucks ... everything is great about the ROM except for battery life (and I guess some of the other crap they still haven't fixed like the physical keyboard lag, grr). It's faster for me than most of the deodexed ROMs I've tried that took out all the Samsprint "bloat".

Wow... I his noticed that my rom somehow fixed the system apps bug...

Odd, I left GPS and wifi on took a nap, five hours later and I'm still at 100%. Of course GPS is not working for me, so now I have to go through that whole rigamorale of getting it to work. Oh yeah I'm on the EF10 modem.

Huh, I had the phone running for 5 hours in a real poor signal area after I flashed EF02 and at the end of the night I was still at 70%. Today I'm going through the usual battery calibration stuff so I won't know for sure for another day or two, but initially it seems pretty good on my phone, (using EF02 modem).

Hm that's weird with 2 hours of usage screen on for a little more than an hour, wifi on the whole time and I still have 79%

Same for me. My phone was almost dead after a long night of sleep. I went back to srf. Stock rom's are boring too

My EE03 was killer until I started messing with themes and then it went to ****. EF has been ok so far.
One other thing I noticed is that when you have your phone plugged into the computer and not the wall it doesn't see it as being plugged in even though it's charging. At the moment I have it plugged into my laptop so it's obviously charging but my screen shows it being on battery for 38 min 52 sec

that doesnt display if you put on charge thats highly unlikely to get 7 hours and still @ 100%

It's not unlikely it's impossible. Looks like a display bug to me.

Or an uncalibrated battery meter. The first battery cycle after a flash can give you some wonky stats, I usually run a calibration and at least one more full charge/discharge before I can pass judgement on battery life.

I seem to be getting IMPOSSIBLY good battery life on this. I've had it off charger for 3 hours + and have been using it like crazy installing apps and configuring. I'm still at 75%.
I fully charged and ran battery calibration when I got up. Who knows, maybe it'll drop 50% in the next hour, but for now, this is stunning!
PS I'm also getting like 15% phone idle, so I don't know if that's accurate.

My battery life is pretty bad too

Hmmm ... EE03 Sucked for me but this is great ! yesterday after 5 hours of no wifi and maybe 3 phone calls and a little browsing in the market i still had 88% ....

It seems that every once in a while something goes rogue in the background and uses 99% cpu that systempanelapp can't see but if I use the memory clear button in the built in task manager and cpu goes back to 2%. Weird

There's about 2 solid hours of screen time there, I wouldn't consider that too crazy. Did your gf realize the screen was on all that time? Your idle drain doesn't look great, try better battery stats and/or watch dog (mixed reviews).

Watchdog is awesome, a must have! But yeah if you haven't calibrated you need to.

Wifi + screen on = loads of watching YouTube clips online while many apps using wifi open will definitely kill your battery.

Admitedly im a minimalist though. I tore out a lot of cm7 and its already core.
Toggle background data off when not in use too. There are a lot of smaller power tweaks though, its a science and takes tweaking.

I had horrible battery life (10% every hour) as well until i flashed the latest Orange UK radio and all of a sudden my battery lasts for two days without charging. Note that wifi is off most of the time and u only use my phone to listen to music on the go, send txt messages all day long and at the end of the day i have around 70%+ battery left.

this time start use from93%

How much did you actually use your S2?

My guess is very little, look at the power use ratio of screen vs. cell standby, they are almost the same. Right my phone is 57% display vs. 3% cell standby.

This looks like barely open SGS2, no wifi , barely touched...

You have never touch your phone.....have you..?? Hey....enjoy your phone and have a normal life..........

Exactly, posts like this are tragic in my book, oh look how many hours i get, anyone can get that if you don't or barely use your phone.

Wow what a pointless first post.. Congratulations on not using phone..
Anyone could get battery life of xxx hours if they never use there phone, it's the screen on time that everyone cares about since generally people with such amazing devices rooted and pimped can't put there phone down...

I get 4:30 hours with CheckROM 4.0 and DK kernel, all values to stock... and that's with playing games! My battery is the stock one.
I guess with minimum brightness, underclock and undervolt and no games i can get 5+ hours but I wouldn't count that as normal usage either.

i charge mine everyday and always excited and looking forward to charging.

Fantastic....
If you wanted to buy a phone you aren't going to use and then brag about not using at all for 100 hours maybe next time you could review this?
Would make you look a fair bit less ridiculous, you would have got the same use out of it and would have saved you over £300...

The only great thing about having such a great battery life and not using your phone is if you end up losing it, which is unlikely if its lying there on the side all the time.. At least you know its bound to stay awake for a few days so you can send over Plan B and locate it. Funnily enough I went on a cruise this year, start of November and after 5 days of no use (being in the middle of the Ocean n all, i went to grab my phone from inside the suitcase to find it was still turned on, (i swore i turned it off) and the battery dropped no more than 40 percent. Was amazed to find it last so long, especially as i've not got the patience to leave it dormant for so long.

keep your galaxy off and the battery usage could be increased to a year lol

bought one of the best phone in the market and not using it all features? rofl
dont have what to say

This post is similar to "Hey look at my mileage of the car that is parked in the garage".
Kinda pointless imo.

Lot of comment you got there LOL
Mine are using about ½% per hour in standby (little sync, good 3G connection, no Wifi), so it might last for about 200 hours (8 days) ... if I ever should go into some kind of long lasting coma where I couldn't use my phone

I've been waiting for my battery to die. This is my normal use. I just do what I normally do.
Streamed music to my car while driving for a while
browsed reddit/xda and other forums a lot... mainly on WiFi.
Had data/wifi disabled when I didn't need it on... really no point. Takes 3 second to enable it again
~50 texts with a few MMS sent. I'm not a popular person
checked voice mail once.

Btw That was an old screenshot I just had in my gallery from not long after I got the phone.

Ive gotten 34 hours out of it so far im really impressed

I have the moto Maxx, Mexican firmware. I´m from Argentina.
Could you tell me guys the version and the baseband of yours?
Because it seems that the latin america version the battery is barely poor.
Thanks!

Damn... Going beast mode with this battery. Would've gone longer, but gotta use it more tomorrow when I'm out. Ya, I know I only have 4hrs of SOT. Haven't been using much

I assume anyone getting more than 48 hours of battery life is turning off data, or at least disabling updates/background data. Just out of curiosity, do you always keep that turned off, or do you just do that when you're seeing how much you can squeeze out of the battery? In my mind, the big reason to get a device with a big battery is so you don't have to baby the battery like that.

I disable data and auto sync. I've done this for every phone I've ever owned. Not to preserve battery life, but I have no need to have it on 24/7. I turn it on when I need it.
