Battery love (life) on VillainRom 1.4.0

So i'll cut to the chase, Battery has been ok with stock rom, after freezing the **** out of some apps, BUT, with VillainRom the phone is working perfect + battery life is amazing.
What is amazing?
53 Hours and 30 minutes since full charge.
I did charge it in the car for very short periods while using GPS and screen on full brightness.
How was the phone configured?
- Wifi/3G Data on at all times
- Push GMAIL and What'sapp
- Screen Brightness on full and the "Adjust screen power" option ticket off.
- Lookout installed and running in background.
- Bluetooth always on, not always connected though.
- 3 Hours of display usage
- 1.5 Hours of calls
- Some gaming, browsing etc.
Don't believe me?
Here are screenshots!

Thats really good but i couldn't get anywhere near that, not even without using the phone. I average no more than 10 hours.
Well done mate i wish i could manage it myself.

and the "ups" in ur screenshot show charging..
anyways let it sleep in peace..

I'm addicted to gaming on this thing, unfortunately that chews through the battery

so many "charging" peaks lol
isnt that the guy who posted the same thing 1 day ago ? XD

Anyway still don't understand what's good about this battery stats ...

@sumeshd,
You know, I don't get money from Samsung or anyone else for posting this? Why would I lie? Anyway, believe what you what, I really don't care that much.
I'll just say again, brightness is @ FULL.
3 Hours, is not ONLY, that's my usage, and you don't have to like it or not.
@bilboa1,
If I wanted, I can charge the phone almost 24/7 I got a charger my car, at home, at work, and even a portable solar one.
The charging peaks you see are mainly USB file transfers for a few minutes, and the long ones are around 30 minutes while driving with GPS + Screen at full brightness.
So the consumption on those moments is rather high, which means the battery isn't charging all that much.
@Mittaa,
You take a 4.3" Smartphone that does everything, and get 53 hours out of it, it's not enough??
if the little charging peaks were not there i'd still get around 46 hours from the phone, is that not enough???
Anyway the information I posted was to help people who are trying to choose a ROM, chose this one, or other people who are having battery problems have a reference.

eitama dont bother posting let this thread die please .
Two reasons one you will find certain users insist you have poor gps yellow screen bad battery life etc . Not worth bothering with if you are happy with your phone .
Reason two is a bit selfish as posting VR great battery life means we are going to get hundreds of numptys posting in VR rom thread who wont read and cannot follow instructions .

I'm tempted to swap over

Having a superb battery life with VR 1.4...just over 10 hours with more than 6 hours screen on time..in a crappy signal area..this is a 100% increase compared to my desire HD with same pattern of usage..
Brightness in auto/ gps when needed/ bluetooth when needed/ wifi when needed/ auto sync & bckgnd sync enable..
Heavy use includes
Whatsapp
Instant messaging
Ebook reading
Music
Browsing
Gmail push email
And some phone calls texting etc etc..

Nice to hear that your happy with your phone ... i'm happy too
I also understand that this is way better than your old desire HD (same for me moving from my old HTC Touch HD)
But I can't understand what this have to do with "whatever Vanilla Rom" ...
Lots of people can get this kind of battery live using stock unmodified, non rooted SGS2!
It could be very usefull if someone made a exact compare between two SGS2 running different ROMs.
First same configuration (screen brightness, auto update, widgets etc) then full charge.
Then 15 min GPS (same route), 15 min browsing WIFI (same websites), 15 min gaming (same game), 15 min talking (same person (sorry bad joke)).
Al together 1 hour of heavy identical usage.
Finally screenshots of battery stats and post here on XDA so we all can clap our hands for the best bettery saving ROM of the week

Well I tried to drain the battery on vr playing games etc to calibrate, and struggled, like noonski did.
I could drain stock rom with ease, but can't do it nearly as easily on vr.
The general consensus from reliable members like nobnut and jje seems to concur with it being better

well as I said I have tried all the roms..
I have tried vr4..for many days..it gave me 9+ hrs..
good u r supporting vr but not good that u r filling threads with "anything"
this is my battery with batista70 rom..and I m happiest with it..
PS: note the screen wake time bfor commenting..(its awake most of the time bcoz my heavy txting and use)..
and I am on 3g/h network with data active all the time..
this is the best I could get till now(with my usage)
no hard feelings..

People seem to be getting time between charges that vary wildly, but for me the biggest indication of battery life is obviously 'display on' time, and this seems to be roughly the same for the vast majority. Best I've seen so far is 4 hours, and that was mainly 3G/HSPDA browsing. My most recent however was slightly over 2 hours with VR 1.4, and again that was mainly browsing with data.
So while a screenie showing over 2 days may look impressive, it's how much actual use the user got that's important. The post above that showed over 6 hours was certainly impressive, but how much 3G browsing was done? How many 3D games played? GPS? etc etc

<shamed> - sorry for long post!!!
@ OP - you had a few minutes under 3hrs of charging. That is in excess of a full charge of the battery! And a total screen of a a few hours.. Nothing impressive at all. Saying you had on GPS and screen on full brightness negates the charging is just silly. It is usage, and usage is what we're interested in.
@ mittaa + Zedwings: Completely agree with both. Even display on (IMO the most accurate comparison) is a long way from the full truth for comparison in testing and a very fixed test environment would be needed to test a pattern of usage. I started to think about this like mitaa suggests (and when you do, you realise it is virtually impossible to co-ordinate without resetting back to factory) and there are still variables.
And anyway, it's kind of irrelevant at that point. You wouldn't consider doing it unless you're battery life is not meeting your hopes or needs. but your usage is your usage and you'll be happy or not.
Unless you are prepared to compromise on screen time, game playing, widgets, sync settings, live wallpaper etc, then what does it matter? You must find the balance between battery life and customisation that YOU can live with.
Personally, I do this by running my phone in 'full fat' mode. All radios on (this inc. GPS), synch on full, screen set to about 75% (no auto), the widgets I want, high spec live wallpaper (like Galaxies!) that make my £500 phone look like a £500 phone. I settle into my daily usage pattern, charging whenever I need to charge. This is why I bought my phone, not to immediately turn everything off and play the 'longest, littlest' game!
After about two weeks and this has settled into a fairly regular pattern, I start to switch off the things that mean least to me, one by one, day by day until after a numbers of days I find the balance that I can live with.
Personally I start with turning into perm 2G mode as I have wi-fi almost everywhere I go and I live in an area where 2G and 3G is on the cusp. This is extremely draining to batteries (I deal with none phone GSM equipment every day where battery life is key) and I know signal stregnth on the band you're using, constantly cylcing between band (and the variance in antenna power) is the single biggest thing to affect battery life asside from screen. It may not reflect this in stats, but trust me on this... If I lived and worked in a strong signal area, it would drop a few places down the list, extra call quality is nice as well as data.
For those of you living and working in London for example, but mostly out and away from Wi-fi, then consider leaving 3G on, and turning Wi-fi off.
Wi-fi scanning for networks constantly is another big drain.I have noticed this about Android, it allows you background apps to work leaner than the iPhone in power consumption when you have lots of widgets and synch etc. However the iPhone actually uses GSM to perform background tasks when the phone is off (shutting down wi-fi radio which reconnects as soon as you unlock the screen). This means that if you're out and away from a friendly hotspot all day, battery is less affected than an android.
Anyway, sorry for the long post, but hope you all have luck in finding your 'sweet spot' in usage / customisation.

Well, that's good. Recently I got a total of 16 hours including 57minutes screen on time.

3h screen time on is nothing, on 2-3 days it's called very light usage.

I Finally Did It! (24 Hour Battery)

I have been desperately trying for SEVERAL months to find a way to get my Samsung Epic to last ONE DAY. Many of you might say thats EASY but not for me. You see I am a POWER USER. Not one of those send a few text message, listen to some music, play a game or 2 users. I actually TALK on my phone a LOT.
I purchased a Yoobao 2800 MAH battery a couple months ago, thinking it would solve my problems and to my dismay I could ONLY get about 5-6 hours with the way I use my phone. So I began searching for apps and configurations that would help me achieve my 24 Hour goal and yesterday I finally found a configuration that works.....
My Results
Battery Life 25 Hours which included 4 HOURS OF ACTUAL TALK TIME W/ BLUETOOTH USAGE
Including 3 email accounts (2 Yahoo set to 1 hour check and 1 Corporate "PUSH" email)
A WHOLE GANG Of TEXT AND PICTURE MESSAGES...LOL
What I Have
Samsung Epic w/Yoobao 2800 MAH Battery
Running Stock Rooted EG22 (Leak) and Generation X "Green" theme.
What I used
Set CPU:
Set up profiles for maximum battery save when screen was OFF and when battery went below 30 percent
Juice defender (Free Version)
Tweaked for maximum efficiency using advanced settings
What I did
Themed everything as dark as possible (Go SMS Pro, Go Dialer, Go Contacts)
No Live wallpaper (Ovious...lol)
My Findings:
Contrary to popular belief....Tasks running in the background IS NOT the biggest source of battery drain. HAVING YOUR SCREEN ON IS! I was having NO success with any of the top task killers so I STOPPED USING THEM ALTOGETHER. All they seem to do is run constantly in the background (Even when the screen is off) killing apps that will RESTART themselves anyway after a few seconds. Juice defender works in a different way. By cutting off the data connection when the screen goes dark. That means any time Ii was on a call and the screen was dark, my data was cut off. (I dont usually need it when I am on the phone anyway) During this entire process I had a rather light wallpaper on my phone. so Im sure I could probably have saved a lil more battery if I wanted to.
Hopefully this will help some people get more battery life out of their epics. After all, whats the point in having a great phone if you can only use it (the way it was INTENDED) for a few hours.
Good Day To All!

lolz
im runnin ec05, srf1.2 rom, bright red & black theme(transmattered reds made by me) pulldown animation, stock battery, no memory mods, live wallpaper(my theme is mostly transparent so the live wallpaper is playing almost all the time), play pandora average of 4-5hrs a day, constantly checking fb xda email market(i have 120ish apps lol), & i get about 13hrs a charge...
you should try those changes on srf1.2 rom if you already havent... some people running similar setups have reported 2 full days or more...
but instead of set cpu you should try voltage control

Pretty sure when you get a phone call it shuts off 3G anyways. Atleast whenever My phone rings my 3G symbol vanishes completely.
Congrats on the 25hours though

I dont think thats true... I've been on a call using speakerphone and 4g data at the same time... I think 4g data still works if you are on a call

The key to good battery life is making sure your phone is sleeping properly when not in use. If CPU Spy shows 100Mhz much higher than deep sleep, then you got something that is keeping your phone from sleeping. I had a problem with some HP printer monitor on one of my computers pinging my phone constantly on my wifi network that would kill my battery if I let it sit with wifi on at home.

In the bottom right corner up there 1day 8 hours at 39%. I run srf, genocide, juwe ram tweaks, and set cpu with profiles to run the frequency lower as the day goes on.
Edit: I see now that that is a very ****ty picture. Man I just can't get screenshots right at all..
Cd's or tapes?

Talking on the phone and the 3g network use the same antenna, so you can only do one or the other. 4g and wifi use a different antenna so they will still work for data while on the phone.

Its not the antenna its the chipset. Bluetooth and wifi share the same antenna but both can be used at the same time.

Thats unbelievable....

Until the newest RandomRom 2.3 Hawk I had the same problem trying to get my phone to last 24 hours. Now I have the RandomRom 2.3 Hawk installed with bloatware Removed, voodoo sound V9 module loaded, busy box pro and golauncher ex with over 100 apps also. 27 hours and I still have 14% battery life and that has been after using 4g for about 3 hours, flashlight for about 1 hour(teslaLED), played games for about 2 hours combined, sent about 40 emails, texted all day(about 150 texts), browsed the web for about 1 hour, watch some youtube videos for about 30 minutes and used navigation for about 30 minutes(coPilot). That is also with weather bug auto updating every hour and gmail sync'd to do its thing automatically. I am happier than I could ever describe now...I think I will finally leave my phone alone for a while now and stop flashing a million roms since I feel I have the best made for 2.3.4 now.

I get about 18 to 20 hours of normal everyday use out of EG22 but i stay on wifi. on ec05 the most i could get is 6 hours, bottom line no matter what i tried. and thats with a stock battery.

About the battery consumption

Hello, I am a happy owner of the DHD.
It 'a great phone, but as you know, the only drawback is battery life.
I've tried several (few) ROM so far, and one with which I am slightly better is the RCMIX.
Now with this post does not go into details about what set, how to optimize (Sync off, energy saving displays, etc. ...) but I ask all your experience based on the ROM that you have installed:
1 - how to use the terminal?
2 - how long you last on a full charge and use it to do?
3 - What kind of ROM you use?
Thanks to all. I think it will be useful for someone like me, prefer a long battery life rather than three thousand graphicals functions

With normal usage (some SMS, about 30 minutes surfing and emailing during the day, 30 minutes music listening and wifi turned on all day) my Phone lives mostly a full working day. When i come home from work (mostly 8 to 9 hours) i still have 20 % left...

Battery life... it's been quite heavily documented on the DHD fora, but here we go:
1500mah is not enough for a huge screen, especially if you want to use the phone's capabilities. The versatility of this phone means you'll want to be browsing, doing emails, playing processor heavy games etc. Each to his own
So, limit the stuff you sync (mail/facebook, news, weather), or at least reduce the frequency. These things cause "partial wake locks", which stop the phone falling into a deep sleep, after which battery consumption is minimal. Watch out for wifi settings too. Search for BetterBatteryStats (by chamonix) on the Android Apps section of the xda forum for much more detail, and tips.
You should be able to get to the end of the day with a good ROM (eg Leedroid/Revolution - they are very popular, but the threads are immense, which makes looking for information difficult). These ROMs have over/underclocking built in (governors), and you can also undervolt (theoretically reduces consumption too).
Limit transitions, be reasonable with screen brightness etc.
And if all else fails, and you use the phone intensively and can't get to the end of the day, you could invest in a power pack (search Amazon for the New Trent 5000mah power pack, which costs less than €30)

my DHD lasts around 4 hrs continuous screen on, much longer screen off. IMO, LM based roms have the best battery life.
But you could always get cheap $3 batteries for the Desire HD off ebay.

Battery life on my DHD was very bad before i rooted it. I am now running RCMix3D Runny V1.3 and my battery has lasted over 30 hours with alot of use.

Your kernel? Radio? Ril?

with m0rbus called "normal usage" my phone lasts around 48h. using my rom and lordmod 7.2 cfs and my personal governor/undervolt settings.
edit: though this result is not really specific to MY miui rom. one should be able to achieve these results with that kernel and settings on every aosp rom.
edit2: with "my normal usage" it last around 24-30h. this includes gameing, emailing, testing settings for developing my rom, rebooting etc.

I've used alot of roms most of the sense ones seem to use about the same battery life better than stock (they get me through work stock needed charged at lunch) but for a week now I've been using miui I've been home about an hour played about 15 min of angry birds, watched a few min on youtube and surfed on xda for a bit and I just over 40% i think that's pretty good going.

Hi, I upgrade the ROM from the group Android Revolution, and my internet I put on 2G and work with WI-FI, GPS and SYNC ON. My battery life is working about 1,5 day.
Before I upgrade I use a Super-Wire patch from ARHD, I think this patch get this performace.
PS.: Sorry My English. I´m Brazilian.

I dunno guys.. I think all that is your subjective feeling and that ROM has no effect whatsoever on battery. Maybe small, but unnoticable. You never do things exactly the same or have battery charged exactly the same. In order to prove ROM has effect on battery usage you would have to make lab tests, i.e. make conditions the same. Moreover, if you look at the statistics of battery usage, it is clear that the most battery goes on SCREEN. And then GPS. Everything else is just a couple of %. All the talk of turning off wifi/3G to conserve power is simply not true. Just look at the statistics! Wifi takes like 2-3% of the power used, tops! The screen with it's 40%-70% is the problem, and there is no way to reduce that...

exactly....

You could always try to lower auto brightness levels by way of a flashable patch. I found that after doing this the screen was only using between 30-40% of the battery. Even so, it is the screen that always uses the majority of the battery. All the tips regarding decreasing battery by switching off syncing, wifi, widgets, etc are in my opinion a bit misleading. If you have a good radio and corresponding RIL then this will vastly reduce battery consumption whilst still being able to sync emails, widgets, etc with the wifi on. I recommend Radio_12.54.60.25_26.09.04.11_M2 and it's matching HTC-RIL 2.2.0160HM. I'm currently on Orange in the UK and this combo works best for me across several different ROMs.

Moreover, if you look at the statistics of battery usage, it is clear that the most battery goes on SCREEN. And then GPS. Everything else is just a couple of %. All the talk of turning off wifi/3G to conserve power is simply not true. Just look at the statistics! Wifi takes like 2-3% of the power used, tops! The screen with it's 40%-70% is the problem, and there is no way to reduce that...

Yes and no.
If you are using the device, you can limit transitions, underclock the processor (via a custom ROM), flash a patch to modify the brightness as mentioned below. That definitely will help reduce consumption while in use.
However, and this is not collected in the Battery Usage option in Settings, Partial Wakelocks are the main contributor to battery consumption. When the phone is inactive, it should be asleep as much as possible - applications like Phone, Mail, Latitude, alarms etc wake it up for either scheduled or ad-hoc events. If you install BetterBatteryStats you will see which processes are keeping your phone awake & hence in a higher state of battery consumption.
Oh, do NOT buy cheap ebay batteries. They lie about their capacity. The only battery which offers more capacity than the OEM one, is Mugen (search in the Accessories forum), it's 1500mah. That extra power could make the difference in making it to the end of the day, but it costs about $45 I think.

You think this behaviour is normal?
Keep in mind that my DHD are this morning on the deck, and only hotspot is active (with whom I connect from the notebook) and sync only 2 emails to connect every 15 minutes each

Probably do you think may be due to the fact that until now has always been on the deck in charge?

If I charge the phone before going to sleep to 100% and leave it on, in the morning the battery it at like 60-70% which IMHO is really too much. I have sync set to between 1-2 hour intervals depending on service, but over night I set phone data to OFF so it shouldn't matter, should it? Then why such consumption? I understand it over the day when I use it, but at night the display is off, data is off so what could cause this? It can't be syncing since the data is off....

Anyway,
The purpose of this thread and i hope it kicks off, Is for us to post our stats with how much battery life , Display screen time etc etc, we are getting out of our current set ups, Which i think will be helpful for all so we can "Roughly" estimate and compare between ourselves, and to help those looking for a better alternative..

it would probably be more relevant if you post a graph without charging the phone
btw, it's an interesting thread to help choose a battery efficient rom, and to see if anybody really can get a 5 h screen on time with a single charge (like i've read around here), I only get 3,5-4 hours, I'll post my stats later

The screen time highly depends on what you're doing with the phone. If you play somewhat heavy games, you won't get the 5 hours.
But if you mostly use it for light stuff, those 5 are generally easy to get. And even 6 or 7.

So in other words, this thread is simply a big fap fest/look at my e-peen hoedown ?

Ummm Not really Mate,
And well i was in a bit of a rush when i made it...
But of course there are MANY factors that can determine the battery life,
But there is also no harm in us showing what we are getting with our current setups? Im not saying we are going to get 3 days if we play like 4 hours of a game on our phone..
But for some "General Users" this may prove quite useful?
I for one am interested in the post above, Saying that he is getting 3 days, I would love to know his setup , then i can try it out and see if it works better for me?
Thats the only aim of this thread...
So i would appreciate if you didnt use such remarks mate ^_^

Exactly,
I know there are alot of factors with what determines the screen time,
But there is no harm in us discussing what we are getting with our current set-ups and how much use we do with our phones..

Using Checkrom Revolution v4 and neak 1.3.3 kernel
With stock battery

are you kidding me, 7 h and 44 mins , I get almost 4 hours screen, only by doing moderate stuff, (browsing, a few calls, some music, I'll post graphs later when the battery discharges), I'm on cm9, but it was the same before with stock roms, think i'm going to get Checkrom a try, only to see if it can reach that kind of performance

LOL I've seen someone hit 8 hours screen on with Hyperdroid. I'd have to underclock to about 500mhz and have screen brightness on the lowest setting whilst looping a blank video to hit that lmao

Sorry. I'll leave you to fap off over battery life & show each other your e-peens in peace.

No need to say sorry ,
Its a free world and we can say what we want
So please feel free to wonder off..
But phew 7hrs On screen with Check Rom + Neak,
What were you doing when the screen was on most of the time ?
I just reflased Neak with my Hyperdroid rom,
Going to check it out...

Mostly browsing the internet..xda..videos on youtube..whatsapp..email..calling..and some games
Im using a mostly black wallpaper..no widgets and brightness on around 30% with sync on all the time.
Sent from my GT-I9100 using xda premium

These are the results I got today. It's not the best but pretty good.
Info:
• Foxhound 3.0 (KL1)
• Siyah Kernel 2.6.7
• 2000 mAh battery
• All day connected to wifi, 15 minutes max to 3G/H+
• Activities on phone: lots of whatsapp, viber calls, Internet browsing, played a few games for a few minutes (fruit ninja for example), etc
Result as in screenshots: 6 hours of screen time and over 13 hours of standby time.

well here are my stats, not very good from what i see
-the latest build of cm9
-2:36 h of screen on but 31% still left
-about 30 mins of calls, some sms, connected to a 3g network but data on only for about 10 mins and wi fi for about 3 hours
-an hour of music
-about 20 mins of games (apparatus )
I think that I'll flash Check Rom + Neak tonight to see how it goes, tomorrow the 2000 mAh battery will arrive so the next post will be with the new battery

Nice seems like we are getting some good feedback at the moment ^_^,
If we get more and more posts,
I will make some sort of Template Guideline i guess that everyone should follow when they make their Posts...
Im tempted to get a 2000mah battery it seems like a couple of people have upgraded to that, I think i will wait for a bit more feedback from others,
Still currently testing my Hyperdroid + Neak 1.3.3 at the moment,
Will see what i get out from it..

The 2000 mAh extanded battery is very nice. It adds about 20-35% battery life. What I also like is the new back cover that comes with it. The back becomes "flush" with that hump at the bottom of the phone. Also, the phone becomes more rounded. It sits better in your hand imo.

How I upped my battery life

Hi all,
*
Throughout my <two months with the S3 I generally got 3.5-4 hours on screen time in an 8.5-9.5 hour window with frequent/heavy usage at <25% brightness before I hit <3% from full charge
*
My day always consists of upto 2hrs HSPA+ browsing+rest wifi, 1 hour of streaming episodes of BBT across home network, twitter, gmail, google+, flipboard, a few YT vids, 5 minutes of calling, trying new apps, bit of gaming etc.
*
I saw a noticeable battery life improvements when I did all of these 2 days ago, hopefully you'll gain:
*
SetCPU profiles. 200/1000 screen on, 200 off, 200/400 incall, 200/800 <20% battery - ondemand
Disable Now, Maps, Whatsapp and NetworkLocationService. *
1-25% brightness
Limit running apps to Keyboard, GoogleMessaging (?) and SetCPU
ScreenFilter
Sync disabled, enabled manually for 30 secs every few hours (just gmail/contacts)
Removed heavy widgets (imo G+ and Flipboard)
Inverted browsing
Wifi sleep timer at 5 minutes
Use wifi whenever possible, however still browse on HSPA+ for 2 hours a day average**
Aeroplane mode 70% of time (wifi exception)
2G when not aeroplane mode and not using data
*
*Using AppQuarantine for a 1x1 widget (click to freeze app/service, click again to unfreeze+open)
**which still drains my battery 1% every <5mins. How can I stop this guys?
*
[Q] Just wondering, what other tricks are there in bag that will help with battery life? Please share!

You shouldn't need to do all of that. All I've done is removed the Samsung Bloatware, and turned off syncing (I'm not an email kind of guy). I have Facebook AND Whatsapp installed (both known to drain a fair bit of battery). Screen brightness at 50-60% and I can get 3-4 hours screen on time over a period of 24 hours easily.

Please please

.....just what I was thinking! May as well just turn off phone, I got about 40 days on my S1 by doing that......fantastic! :thumbup::thumbup:

So, what you basically suggest is to turn your smart phone into something like this:
Sorry..could not resist..

Well, lol. I always get more than 4 hrs on screen. Ive only removed bloatware. Everything is turned on.
Always on auto brightness.

SETCPU is a battery hog, but your main problem is the weak signal you have.

LEAVE NOKIA OUT OF THIS!!! :jk:
Seriously though, I don't mean to take over this thread and turn it into a 'my battery life is better than yours' thread, but I haven't done any of those steps and well, I'll let the results speak for themselves
Full screen brightness . Null_07, Siyah kernel 1.8
Oooh poop, I just remembered that I did under clock a bit but I won't say what settings as I don't know what I'm doing and won't take any responsibility for anyone taking that information and screwing up their device

g33mt4z, great stats especially with full brightness! But they're expected from tablets
m8tik, this was purely experimental and I don't think my user experience has been hindered to an effect, especially to that of a 6300 just yet
Sent from my GT-I9300

Take a look at Null_07 maybe? It comes with 240dpi by default I'll take that tablet reference as a compliment although, just know that it's definitely an I9300 and that bad reception really does kill the battery, I work in bad reception areas and have to turn it onto airplane mode or else it dies shortly after arriving home, still better than my old HTC velocity which never made it home turned on

So you basically transformed your gorgeous S3 into a Nokia 1100 and you are happy about it?

no idea how others are draining the battery because this is really "customer dependant"
but here is mine with this rom: Darky ROM III - 7.2

I remember I did some testing on Hyperlight rom (a stripped one) with Siyah 1.6.8. All I did that time is lowered CPU to 1200 or 1300, UV -100, 3G manager to cut off data when screen is off but allowed to turn it on every 30 mins for emails sync.
5% left, 2h 37m On Screen and 3d 9h on battery

Well battery life and phone usage varies between people. Bad receiption always one of the main culprit. U dont have to turn ur device to nokia 1100 lol. Disable data when u have bad reception.
And check if ur carrier support fd or not. If u got it enabled and ur carrier doesnt support it then it will hog ur battery.
Doing/disabling too much thing just to get a couple more hours.. well not really bright...
Might as well just use nokia symbian rofl. Batery life prob solved.
Using a smart phone, u will want to get the best out of it, not to get it less than it should normally do.
Just my opinion though.

Can't agree anymore! We are using a smartphone, but not preserving the battery of the smartphone. As long as removing all useless Samsung boatware and undervolting, say 75mV, then it's good enough!
