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.

anyways let it sleep in peace..

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

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.

Hi guys,
After buying s2 i was worried about battery life. Because first two days it was like 12-14 hours of medium use.
But now its marathon :d

I thought i was getting good battery life with medium to heavy usage (27 hours) on Cognition 1.15 but that is exceptional, can you tell me your set up as to how you achieved this amount of battery life.
cheers

Tegrak's kernel and underclocked.
Frozen samsung apps. and brightness mostly 0% as i am fairly fine with the lowest brightness it doesn't hurt my eyes.
also one more thing, i am using overclocking upto 1300 as well and you will be surprised most people will tell you to go underclock to save battery but i didn't and i am just happy with 1.3 Ghz blazing speed.
Here's a shot of running.
REMOVED
Also i used camera for recording movie for about 50 minutes in 720P and 50+ photographs as well which is not mentioned in the above post. I will post once again when my battery will reach 1% because when its below 10% it drops really slow and allows me to use it more unlike when its full.

Sit it on a desk and stare at it. The average screen on time is 5 hrs. You can use that in a day or spread it across 3 days.

One more thing, i only recharge battery when its below 5% or mostly under 2% to full turning it off. And ofcourse this only first week of using the phone, hope it will increase a bit more by next week.
[Note: I personally believe plugging in and out of charger makes the phone battery drop faster]

You should blur out your IMEI number from the screenshot buddy.

What ROM are you using?
I usually have brightness set to auto, same as you all Samsung apps frozen, am not using Tegrak i don't believe it's compatible with Cognition ROM, are you using Juice Defender Ultimate or other apps,etc,etc, im on setcpu im 200 min - 800 max - on demand and screen off profile - 200 min - 500 max - consertivave - priority 100.
Seriously impressive all the same..

That is the best battery life ive ever seen on XDA for any type of smartphone never mind one like the GS2, did you use the Internet/Wi-Fi/GPS/Bluetooth,etc, much,do you have any widgets on your screen, push e-mail,etc, im amazed your getting that amount of time without using Juice defender or some other similar app.

Bluetooth yes for 10 minutes transfering some files.
Gps yes for around 1 hour (you can see that in pics atleast it shows usage for ndrive there)
wifi yes around 1 hour but its always on mostly (mostly used for market to download and test applications, gmailing and also some browsing)
3g or edge no i didn't use it.
Games yes i played like drag race etc.
widget yes, battery widget and the running app widget and live wallpapers.

Mine, I think there's a little (big) problem :
Considering the first 8 hours were during the night so I didn't touch my phone :
Running on VR2.1, many things push or so (like 15/30mins refresh) [mails, fb, twitter, news, weather, etc], and good modem (KG2) and CF-Root 4.1.
Any idea/advice please ?
A better rom maybe ?
Thanks in avance

The real secret to great battery life is to disable all the data connections and not use the phone. Since most people are pretty active with their phones, threads about stand-by time are pretty meaningless. Actually, with over a dozen battery life threads already running, you could say new battery life thread are pretty meaningless too.

I'm on stock K2-CL. I used 3G just a bit today while in a restaurant, wifi is always on, but I normally sit in front of the computer most of the day, or use my tablet at home, so I do very light surfing - mostly while on the can.
I've not installed "app freezers", nor underclocked the processor, nor rooted or removed anything that isn't stock android. Not stopping tasks in the task manager. In the screenshot below, I did play around a bit on Google Earth for 15 min or so, I'm surprised not to see the android market in there because I feel that's what I used most. I use a live wallpaper that's fairly bright (moving clouds).
Brightness on auto - automatic gmail notifications, contact syncs etc.
I'm going to go on a big trip next week, where electricity will sometimes be optional. I do have that Samsung battery case thinggie coming the mail next week - and already have an external battery as well for emergencies, because this phone will die in an hour or two using the gps, or playing games, or doing serious web surfing - or a combination of those things. It runs very hot too if you use it constantly several hours (drove 500 kilometers last week, the phone was very very hot - seemed unhealthy).

If you hold the power button along with the home button it takes a screen shot.
Thought id say to make it easier for ya in future!

thanks a millions

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.

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.

[Q] Disappointing Battery Life

I got a Nexus 4 yesterday, and so far it has been excellent. Really fast and has all the features I want. The battery life is pretty poor though. I am at 28% with a screen on time of only about 2 hours. The total time is about 8 hours. I haven't been using it a lot. The main thing consuming battery seems to be Nova Launcher for some reason. I have it on my Nexus 7 and it doesn't decrease battery life at all, but it seems to use a lot more on here. It was at 24% according to GSam Battery Monitor.
I just followed a bunch of instructions for increasing battery life from various websites so I will see how it goes. I now have all the Google syncing disabled, location services off and brightness on auto.
Is there anything I should be doing? Why is Nova Launcher's usage so high?
Thanks,
EDIT: Could it be the widgets I am using? I have two Gmail inbox widgets, the messaging widget and the circle battery widget.

Same here though I'm not sure its nova, my battery got as bad as yours when i rooted to stock.

it could, or any other apps you have working in the background. it can also be how you use the device. but before you assume anything about your battery life, give it 3-4 battery cycles before it normalizes.

Alright. I have minor OCD kind of thing so I always close the active apps through the task manager as soon as I exit them. I'll give it a few more days and then pursue the issue further.

im ocd about that too, lol. the back button to kill is one of my favorite custom rom features. also, autostarts and greenify are both great apps to make sure that you have mich less ctap opening in the background. anyways, im a heavy user normally, battery life on the nexus 4 id never call bad. usually i get 3.5-5.5 hours screen on time, depending on use. but then again, i use a custom kernel thats optimized for performance and battery. but, stock rom/kernel isnt bad on battery.

I too Force Close all the social networking apps before sleeping and turn wifi off. And i daily get around 4 hrs of OST. Will attach pics later to show. So to get 4 hrs OST you need really need to have a custom kernel. Just optimize your usage and you are fine with the stock kernel.
Phone is totally stock. Not rooted. And i got 6 pages on Apps installed.
I even used to clear RAM every now and then but I just stopped doing it as I couldn't find it doing anything better.

The battery life is much better now. Yesterday when I got back from school it was at 40% or so, and today it was at 68%.

Gets better after a few battery cycles. My battery life was average, so I rooted and with matr1x kernel it's snappier and better battery.

i'm stock and my battery life was shockingly bad on the default settings until yesterday when i tried some fixes and they have made things much better.
looking at my N4 right now, i'm still on 58% after 22 hours. that's after several voice calls, some browsing & reading emails, GPS navigation using Maps, a couple of skype video calls, wake-up alarms etc.
basic fixes as follows:
- screen brightness right down to maybe 10-15%
- data off when not being used, ditto location services
- NFC and BT off.
- i've left wifi on as it doesn't seem to take much battery if it's not being used.
that's all! after charging last night, i woke after 6 hours or so and was amazed to see it had dropped only 1-2%, so apparently nothing is waking it from sleep.

One thing that really improved my battery life (when I had a Nexus 4) and something I tell to anybody with poor battery life, is to go into maps, go to settings, location settings, and uncheck "report from this device". If you've got the app "wakelock detector" just watch the wakelocks from maps almost entirely disappear. It nearly doubled my battery life at the time.

Hey thx man that didn't work but it did start me down the path to fix my problem.
I found out it had something to do with my GPS options its in settings and location access WiFi and GPS location options i checked it off and now i am getting 1 hour screen on time for every %10 if you do the math i have about 8hours of screen on time! I also have setcpu app which is giving me about 48hours of standby time, i will upload some screens after a bit more testing.

My battery life is brill and i never turn owt off or force anything to close, it is only bad when i play a 3d game or something but what do you expect. over night it only drops about 1% every 4 hours which is a bit bonkers.
(screen on auto, fully stock with Nova and not rooted)

Lol, so whats a custom kernel? cuzz i think I don't hav one because i hav rooted stock rom. sorry not to change subject
Sent from my Nexus 4 using xda app-developers app

first day of full use in my nexus 4 I got 5 hours of screen on time. stock rom and kernel, just rooted. I think it's pretty decent.
just do what people say, disable location useless stuff and monitor your wake locks.

If you would like to risk such things as unlocking bootloader, rooting, installing custom ROM and kernel, then it'd be easier for you.
Personally, I've found codefireX ROM and faux123 kernel to be battery friendly and very responsive, but of course you've got to be a bit fixed on such things as playing with your devices and getting fun from it to do that

another update:
after 20m browsing/ emails this morning and a couple of calls, i'm down to:
2d 9h 18m and 11%

S4 Charges fast and Discharges fast

Hello,
My S4 is nearly a week old now, it's the international GT-I9500 octa-core version. Since it dons a big battery of 2,600 mAH (middle point of S3 and Note 2) it was suppose to last long more even with heavy usage.
My usage is moderate, a few calls, but I use connectivity extensively i.e. WiFi indoors and Mobile Data outdoors.
I tried switching off the WiFi to preserve battery and to see any boost but zilch.
Whenever I put the phone on charge, it charges very quickly and when the charging is complete and I remove the phone from the charger, it discharges pretty quickly, goes to 99% in a minute WITHOUT any usage.
What could be the issue? I even formatted my memory card from S4 as I read some bad mp3 files or something can cause the battery drain and such.
Everything is stock, both ROM and Kernel and the phone is not rooted atm
I'm attaching the screenshots for my cycle with minimal WiFi and Data usage.

I can get more than 16hours on my S2 easily with average usage...This is just BS optimization from Samsung...

It's better than the s3 because the battery is larger but I'm telling you that screen is a hog. It's larger and brighter and its 1080p; yes the resolution causes the gpu to eat more battery too.

I freaking hate watching my battery drop.. and mine goes by quite quick. . I have wifi and mobile data on.. When I leave my house I toggle off wifi. I read that having mobile data on all the time doesn't use battery. . Is that true?
Anyway. .I just turn off the battery percent.. Can't stand putting the phone to sleep at 80 and turning it back on 20 min later at 75.

im wondering if there's a way to switch the screen to 720 mode instead of 1080p to save battery life. similar to switching a computer monitor so you stress the gpu less during a game... this would also save a small percentage of battery life...
also a more efficient auto-brightness would be great.

Same here, hate watching the battery drop so soon. For me, what I've observed is that WiFi eats a lot of battery than mobile DATA for this set when it should be the other way around...
I have my internet disconnected at home due to some upgrading of the lines in my area so I haven't been using WiFi at home, only at office, so mobile DATA was switched on all day yesterday at home and when I go outside and surprisingly the battery didn't drain a lot.
I'll post screenshots of this cycle as soon as the battery drains down to 2%

No! Mobile data is one of the biggest battery killers going! I have my toggle within the first 5 so I can turn it on and off when I need it easily
Sent from my GT-I9505 using xda premium

With big screen and higher resolution, it will definitely consume more power. try to turn off screen and kill running apps when not needed.

16hours on battery is quite good considering the WIFI indoor and Data on.
i probably get a little bit more than that but less wifi usage and data is only EDGE in my country.

Nothing alarming
Firstly, your stats are perfectly normal. I got the same results on my stock octa core version.
Try omega its much better battery consumption wise. Other tips: Switch to 2g only if you are using your phone just for chatting, keep backups off and turn unnecessary sync off. Turn off your screen tap sounds.
You might already know all this.
Anyhow, trust me 16hours at 60% is not bad. Hopefully samsung will do something about it with future updates.
CHEERS.
Ow and if you are over with your honeymoon with all the air motion gestures smart eye tracking features, turn them off if you want to save some more.
