[Q] longest battery life?

Hey guys! I'm going to a trip to Poland to see Auschwitz and all that stuff about the holocaust with my class on the nesxt monday, and now i'm wondering which rom for our device that got the longest battery life?
I'll just be able to load the battery on every second day and i want to upload 2-4 photos everyday to facebook and i want to be able to take photos without the batterys going to 1%
Right now I'm using SwiftDroid but the battery isn't that good, so.. which rom do you think i shall use?

2.1 custom roms are good.

sanmit: Which of them do you think is the best? And do them got Swedish/Svenska as language?

Stay on SwiftDroid, but reduce the clock of the CPU to stock 600MHz (or lower) max and 122MHz min. Try to turn off any fancy animations of menus etc. Use static wallpaper instead of live one. Turn off screen rotation, wifi, BT, GPS. And AVOID USING THE PHONE until You need it actually (reviewing pics etc).
That should maximize Your battery charge.
Have a safe trip and have fun!
P.S. Oh, and I forgot to mention to turn off (remove temporarily) any widgets like clock, weather...
Try to find a compromise in all this stuff and stick to it.

MomirPeh: I'm already using my phone like that and still the battery is kind of crappy

I think the Quarx 2.1 rom w/ his custom kernel is very good with battery. If you want to try it, download it from my Dropbox In this .zip is the system.img, boot.img and an update.zip file. The update.zip file contains a fix for the device rebooting when Wifi is turned on. You HAVE to flash this .zip with Clockworkmod 2.0 (2.5.1.8 recommended)
Hope it helps,
Jack

Swedish language support...not sure.
But i can say 2.1 mmxtreme advanced gives me 3 day usage with moderate audio-video and wifi.

Just use the Open Europe v20B stock ROM. No custom ROM gives a battery life better than a stock one. And one small tip. Do not use 3G. It drains that battery much faster. If you gotta use data, use 2G.

Definitely 2.1 mmxtreme Advanced Lite rom! I use my phone quite often, and no rom gave me more battery than that one! Turn of background data, 3g, mobile data, and other stuff like that. Use an advanced Power Widget or ZDBox to have them all "use-ready" all the time

i've got 7-8 days without wifi/GPS and other....just calling and so.
on swiftdroid 1.8 (cpu speed :MIN:245/MAX:600 [MIN:122 was way too slow on phone startup])
but on 1.9 i've got ~3-4 maybe 5 days at same cpu speed

Battery
My recent Froyo Optimum (aka superfast froyo) v3a has a exceptional battery life, I gotten 3 and a half days with moderate use, like messaging the girlfriend all the time and couple hours with wifi and angry birds. Also my 3g was switched off and so was GPS

battery drains completely in less than 12 hours

On Galaxy S I9000.....what can I do to fix it? This happens even with minimal usage.

I have this issue on Darky 10.1 (2.6 kernel), 2.3.3
Battery lasts around 10 hours with light to medium usage (its a new original Samsung battery as well).
Does anyone have any quick advice to fix this? Bit under time pressure due to job at the moment and don't have much time to research this. Any advice to fix this easily and quickly?

I had this problem after switching on the “Vorabruf über Mobilnetz“ in the Cache-Settings of Google Maps. Maps was closed, but battery was fast going down. Using XWJVH.

I too have almost the same problem with Darky Rom 10.1 - but I've heard that it has been fixed in the new beta version. I'm gonna flash it at the end of the week and after a few days of observing, I'm gonna tell you the results.

It's been through quite a few cycles.

I think I figured it out.....I think it was Skype. If you sign in the app is always on...it doesn't have an exit feature. There is, however, an app to close it. I used it and got normal battery life today!
We'll see if it keeps working like it should.

So I've upgraded to 2.3.4, (Ficeto.Deodexed.XXJVP) and Android OS battery drain stopped. Now it shows 70% battery usage on display (before it was 70% android OS). I recommend updating your system too

with darky on medium use never had more than 14 hrs )

I've given up for the moment and gone back to Darkys 9.5
Now at least I can get through one whole day and have about 40% left

Are you willing to flash the rom again? or you can try to use the speedmod 15g t11 for the kernel to replace the JVP kernel.

it's said that when you use the USB connection to your PC, you need to reboot it. So this battery drainage will not happen.
In the ROm 2.3.3 JV5 and JV6 for Asia, I do the same to keep the batter alive.

Try backing up everything and then factory reset phone. Generally this happens because of a few unwanted applications excessively using ur processor, in turn draining battery or there may be a malware that stealthily connects itself to the net. This will almost certainly cure the disease. If it doesn't, then there is a serious defect in ur hardware or some of ur system app required for properfunctioning of the phone is corrupted, causing excess pressure on the processor

It is a big problem to everyone, I charge twice per day for this.

Calibrate your battery
Let the battery go down to 0% and turn off
Then turn the phone on, it'll turn itself off again cause battery is low
Keep doing this until its totally 0%
Plug in the charger, charge it to 100%
Turn the phone on
Download SGS Tools from the android market place
Run the app
Go to "scripts"
click delete battery stats
Unplug charger & you're done
battery should be more stable now
go to settings
applications
running services
check what you have in the background
close them down if they're unecessary
I get through the workday with only 10% loss

If you have an really old SIM card, try and replace it with a brand new one. This may also help. I had bad battery run time with two LG Optimus 2x phones (about 10 hours) and not so stellar 20 hours with the i9000. Finally I stumbled over some advise to replace old SIM cards. Since mine was over 12 years old, I ordered a new one. It is not gonna change the world, I know, but it was worth a try .

Any ideas

Hi there,
Firstly, I would ensure we rule out a hardware issue by flashing a completely stock firmware using ODIN. It would be best if you remove your external SD card, and backup all your data on your internal memory and then wipe as much as you can as well. After flashing a stock firmware, see if there is a battery drain still, and if so you will at least have more evidence to suggest there is a hardware issue.
CPU Spy is an excellent app for discovering issues whereby the CPU is being utilised too much - additionally, System Panel is also excellent. However, again neither of these will be able to determine if there is a hardware issue of some sort, only excessive CPU usage.
WRT EFS backup, my preferred method it to use Root Explorer and create an archive whilst in the EFS directory. It will put the archive on your SD card - and it takes no time at all.
Some of the apps I mentioned will be charged for I guess, but not very much.
If you need more details, let me know.

:-( my battery was perfect. I installed onecosmic and it was fine battery was normal after few days my battery started draining fast 1% every 3 minutes and I flashed Miui mintberry rom and still problem exist. Even wifi off and background data off and edge too it drains 1% 3-5 minutes while screen is off or deep sleep it drain 1% evey hour
Last night I flashed back to stock rom 2.3.4 and rooted and installed Miui mintberry rom again still problem exist
What should I do :-( plx help
Sent from my GT-I9000 using Tapatalk

ok.
You need to examine this problem to narrow down the cause. You will have to invest some time and possibly a little money to achieve that! If all else fails, you can of course buy a new battery - but it's best to work out where the drain is coming from.
Have you checked the battery log in Android settings?
Also consider installing OS Monitor, it is free and allows you to look at what processes are running.

That's quite some drain!
It's important to get the right tool for the job here and the apps you are using aren't detailed enough unfortunately.
System Panel will inspect android system apps to check where CPU usage is and log it making it very easy to determine what is happneing.
BetterbatteryStats will allow you to check on the WakeLocks which are a big cause of battery drain when the screen is off.
I use them both - but must say I haven't see such fast battery drain as yours.
Throughout this process, I suggest you stick to a ROM as close to stock as possible but prefereably with CWM.

ok; excellent.
If you need help turning on the "monitor" mode of system panel let me know. Otherwise just turn it on and then use your phone normally for a while (i.e. allow time for it to be left with screen off as well) after that stats will be collected to show how the CPU has been used over that time.
Also check CPU Spy and make sure that the CPU isn't "stuck" in 1000Mhz

i am on official with cf root kernel and been on for 13 hours with 11% used. superb battery life for me

LPY with CF rooted kernel, 3h of voice call, wifi always on, auto mail check every hour (3 accounts), ebook/comics reading.
1 day and 9 hours on battery and still have 31% left. Not bad for me, round 2% per hour.

Surprisingly that airplane mode -> turn off phone -> pull battery -> turn on phone -> disable airplane mode trick worked for me. Also the pull battery part was essential for no idea what reason.
Now after almost 4 hours intensive use I still have 70%, kinda meets my expectations now.

This is one thing everyone should try...the other thing is (as always): Use the ROM for a week or so! Load and reload it a few times (100% - ~5%)...the battery has to "settle" every and each time you flash a new rom.

mine seems fine. been sitting next to me for the last 4 hours and so far it has lost about 3%

I am also having a horrific battery life. It was much better with both stunner and cm9. I am trying to go back but not sure how to. Dont want to flash anything and brick my phone.

In my hands, the airplane mode trick works, but toggling the energy saving menu restores the no-deep-sleep battery drain state.
Connecting and disconnecting from external power or car dock doesn't seem to precipitate the drain, instead.
Please try yourself to confirm.... In this first ics firmware, knowing what to do to make it work at best is of great importance.

Samsung Galaxy S3 *AWESOME STOCK BATTERY LIFE*

THIS THREAD WAS INSPIRED BY MOST OFF YOU WHO ARE TRYING TO GET MAXIMUM BATTERY LIFE WITH SOME CUSTOM ROMS.
Before Galaxy S3, I had Galaxy S2 which battery wasn't soo good. I was always searching for battery friendly roms and I was flashing one or two roms every day.After every custom rom I was thought like that: Why I done that, when every stock firmware gives better result(battery life and performance) then any custom rom. I know that there are some excellent custom roms, for me ,these are STOCK LOOK roms with bloatware deleted and some unused apps. But, we don't need to flash them when we can do that alone.
NOW,I HAVE GALAXY S3 :
Let's see my result on stock battery,stock rom (4.1.2 , DDELK1,XXELLC), and with some apps turned off in application manager,battery saving is turned on just for color of backoground,nothing else.That was heavy usage,I installed that firmware updated, all appps that I am using , and charged it. Viber,WhatsApp,Instagram,Sync,Wifi,3G,Facebook,Gmail, are always ON.
Results:
4h of screen on,phone was used(wasn't just screen on) , 52% battery left. I lose about 3-4% maximum during the night ( 7-8 hours) with wifi on.
See this on attachments.
Mostly ,my battery lasts for 2 days, I achieve min. 5,5 hours screen on in every charge with hd gaming,facebook,gmail,whatsapp,viber, about 40min-1h talk in 3g every day.
My tips for battery life improvement are:
-Turn the Energy saving(I turned it on just for background color i vibration,if you turn on full battery saving you will get much better result, but it seems to slow and laggy)
-Turn off apps that you aren't using in app manager( Settings,Application Manager,All > than find apps which are unusal for you. I turned off : All yahoo apps,samsung suggest,google +,flipboard,dual clock,chat on ,all samsung hubs because they doesnt work in my country, google maps(I use google earth).)
That's all. Enjoy that battery,that performance and that beauty of stock rom

Hi Guys,
This is actually my 1st post, but I was looking around xda for couple of months now.
I am using stock rooted XXELLA with Siyah kernel. I can make my phone last easily for 2 days, with 2g mostly on, disabled lots of unused apps, lowest brightness, sync off, etc. and UC to 1200 mhz. I'm using pegasusq gov and noop scheduler.
But I can't imagine 4 hours screen on and get 52% battery left, or get 7,5 hrs totally. I always monitor the usage with BetterBatteryStats and when the screen is off I can even get about 4-6 hrs / 1%. But I can't reach >5,5-6 hrs screen on. Any suggestions? Do you think I can lower the min. brightness in build.prop?
Btw, I think if you share your battery stats, it would be nice if you also share your governor/scheduler and OC/UV values.

I don't think it would make any difference, since I have only few apps, I don't like putting garbage to my phone Could you maybe share kernel and partial wakelocks from BBS, maybe cpu states too?

Sent from my GT-I9300 using xda app-developers app

Everyone uses their phone differently so comparing battery life is not possible, someone who demands smooth scrolling and instant response is not going to get 2 days use or more than 4hr screen on time.
Personally I'm not worried by stutters or lag, I'd rather get 9hr screen on time over 48hr up time - this is with a super lite ROM, I have all the bell and whistles turned off and all power saving options on, as close to AOSP as a stock based ROM can get.
I'm very happy with this phone, compared to my old htc sensation I no longer worry about battery life, I have two batteries which get swapped over between phone and desk charger every two days, unless playing games when I only get 1 day life.

Hey op, sorry to say this but you might be wrong. For battery life it depends on kernels and tweaks rather than on roms. Roms are actually just themed/stock themed firmwares with additional apps/removed apps and pre-installed tweaks and kernels. Most roms use v6 supercharger tweak. For me I use phenomenal kernel which has undervolted and underclocked gpu and cpu. But if you want more options with oc/uv try boeffla kernel where there"s an app included that allows you to over/underclock you gpu and cpu. By underclocking, it will save more battery. My ohone lasted about 12+ hours of continuous use of my phone (gaming, watching videos) with the kernels I use
