Competition: Best Batter life ROM

any chance of mods running such a comp? with 3 way toggle for battery save, gprs and gps?

you can always add the HTC widgets to the home screen that allow you to toggle all the battery draining stuff. And in 2.1, there's a single integrated google widget that does all the same stuff.

It is so intermittent that it would be impossible to get reliable results. I found brilliant battery life with Villain and average on MCR and really terrible on stock HTC. I get three times as long out of my phone now i'm on Villain than I did on the stock firmware.
However, everywhere you hear so many stories of people having poor battery life on custom roms and such varied accounts even on the same rom's that it would be impossible (at the moment) to get some reliable comparrisons.

I dont know u though about 2.1 or 1.5 but the Kimera v.1.5 , which based on android 1.5, has an awesome battery life

yes tried kimera, will try it again when phones re-charged, might have to give villain 4 ago beofre tho. my normal one is ahero tho.
be nice if could be some sort of benchmark for battery usage like there is for speed tho

I use a program called battery graph to monitor mine. Currently running 24 hours without dropping from 100%

and that doesn't make you suspicious? there is obviously something wrong...

Easiest solution............
Turn it off! If your that bothered about the battery life buy an old school nokia 3310 put a paygo sim card in your HTC just to play with it.
Have you not noticed that as phones get smarter battery life gets lower?
On a side note i charge my battery whenever possible, carry a usb lead everywhere with me as i can plug it in at home,in the car,in the pub,at work etc

And remember - regardless of which ROM you use, if you use a lot of widgets, programs which run in the background or programs which sync often, you will find that your battery life will be significantly reduced nonetheless.
Often you can use a shortcut to an application instead of a widget and get on-demand functionality instead of an auto-updating and battery-draining widget.
Disabling wifi / mobile data / mail auto-syncing / GPS, as well as decreasing brightness and the time the screen is on while not using your phone, will help for any rom too.
Good luck.

You're suggesting I should be suspicious because my battery is lasting like it should be? Currently:
71% left
Up Time: 2d 20h 47m 59s
66% Cell standby
34% phone idle
I've also been texting and internet & market but nothing heavy.
It just depends on what you do with your phone, I wonder sometimes why people think they should be able to have wifi, gps, bluetooth, and every other feature turned on and expect their phone to last more than a day? Does your laptop last a day? and look at the size of that battery. I know the hardware is stripped down but your phone is now essentially a miniature pc so stop complaining. If you get used to turning off all the features which drain the battery you'll see a marked improvement. If you can't turn them off for any reason then buy a larger capacity battery! There are loads around on ebay and other sites. hxxp://cgi.ebay.co.uk/EXTENDED-3000-MAH-BATTERY-REAR-COVER-FOR-HTC-HERO_W0QQitemZ380174233125QQcmdZViewItemQQptZUK_MobilePhones_MobilePhoneAccessories_MobilePhoneBatteries?hash=item5884266e25

Yes because the battery should not work like that, its a smartphone not a bottom range nokia work phone.
like I have said before no smart-phones battery are meant to last longer than say 2 days max of normal use maybe 5 at a really really really basic/no use

A Day and a half use out of an evo with FRESH rom? HOW?!?!?

Since my inquiry was ignored in the original post, I'm going to ask it here, HOW are these claims of a day and a half worth of battery life achieved with the fresh rom?
I just installed it last night with a clean wipe (including dalvik cache) and even erased the battery stats coming from Baked Snack with the kernel listed as "best battery" (which I can't get more than 12 hours out of with hardly any use).
I see claims of a day and a half so I want to achieve that as well, so help me out, here's what's going on with my evo
1. mobile data, 4g, wi-fi were all off. had no need for them for most of the day, only turned on 3g for about 20 minutes when I walked to the store.
2. GPS and bluetooth were off all day
3. listened to a couple of mp3s
4. about half an hour MAX of phone calls
5. about 50 text messages
6. played scrambled net for a while
7. haptic feedback is off, brightness is at around 30%, live wallpaper wasn't used, auto-sync is disabled on EVERYTHING, e-mail is set to once a day, google talk isn't set to auto start, using overclock widget to UNDERclock my CPU, using juice defender to turn off mobile data when my screen is off
I have screen shots posted, let me know where the problem is coming from!

You can tell I wasn't doing anything because the highest percentage of the battery usage was "Cell Standby" and "Phone Idle"
so can anyone help me get some better battery life?

There is definitely something eating your battery because this is bad beyond bad. I would flash a rom and not install anything at all. Set up your email accounts and use as normal but install nothing else and restore nothing else. See what battery life you get then. After that you can start installing apps back one by one and monitor how they effect your battery life.

did u do a full wipe and clean install? i cleared my stuff twice before i flashed and i get like at least 20 hrs...

Use Spare Parts and check partial wake usage, android system should be on top. If you still cannot find the app that is draining you, then flash a custom kernel that supports underclocking/overclocking and use setCPU app to underclock when your screen is off. With moderate use I go from 8am until 11-12 at night with about 20% of battery left.

are you on a stock battery? using fresh rom with kings kernel i can get a day and a half with much more usage then you have. i say reflash everything, radio, rom, kernel, and dont restore any apps at all. run it for a day without even installing any apps (except setcpu or overclock widget) and see what you can get out of it, maybe ur evo is malfunctioning?

Went to spare parts. UID 10011 is on top and slightly more than android system which is second. What is UID 10011?

ok, I'll nandroid it and try that approach.
so completely wipe it again (cache, dalvik cache, battery stats), flash the rom again, and install overclock widget only?
I'll try that - can't hurt nothin...

you should be able to get at least 7 hours of talk time with everything stock, if half an hour ate up 40% of your battery then you have something very wrong with your phone/ROM

and be careful wiping battery stats. Make sure the phone is at 100% charge (not just green light but actual 100%) and THEN wipe the stats. Then let the battery drain to 0 (to the point it shuts down on its own), and then charge back to 100%
That should get the battery back in line if you wipe the stats.

Let me know what your findings are if this helps. I'm in the same boat your in, installed FRESH 3.2 and I'm also not getting these battery improvements everyone is talking about. I'm still using the original battery from when I bought the phone which was on release day.

i wouldnt expect a day and a helf with use. While some are reporting getting it many others dont. "moderate" to "heavy" use varies by person. Many of these reporting extremly lng battry life that detail there usage to me is very light usage.
with that said you are getting pretty bad battery life. Instead of or before you go the route of taking a week to sintall your apps so you can check each one you may invest in system moniter. if you get the purchased version it has the ability to show you history of which apps are using the most battery power.
Also while some people may take offense to this i put a lot of the battery statistics into the sketchy at best catagory. It is similar to benchmarks with computer geeks. We will run benchmarks constantly trying to figure out what gives the highest score. and then we normally exagerate it a bit when we brag because we want to sound like we have the best rig.
now i am not saying everyone is but i would take most of the outragous battery stats with a grain of salt. if someon tells you they get 50 hours with moderate usage regularly. Their definition of moderate usage is probably what most consider as light usage. (ie moderate usage for 2-3 hours of the 50)

would using sense over launcher pro eat up more battery life or vice versa?

I have the Fresh 3.2 ROM flashed last night (technically early this morning). With the stock 2.2 ROM my battery died in about 5 to 6 hours, with Fresh 3.2 its already been 8 hours and my battery is at 29%. I love it! I have spare batteries and chargers everywhere, and I have auto sync on with moderate use today including a few video calls via Qik (not very long, a couple of minutes at best). If it get's better over time I will really be in love, though I wouldn't mind getting a full 24 hours out of a battery.

Does the phone have to be on or off when recharging?
Sent from my PC36100 using XDA App

It also depends on how they are defining a day and a half. Are they talking about 36 hours of usage without being on a charger? I don't know many phones that can do that. Hell, I don't know anything electronic that could go 36 hours without some sort of power/fuel.
If they are talking about an 8 hour shift one day, then going home to bed, then waking up and going to work, and making it through another 4 hour shift, I can believe that. If they don't touch the phone hardly at all between the two work shifts (as I usually don't when I'm at home), I can see that.
My Evo on Fresh 3.2 only dropped 20% last night, as I left it in the living room when I went to bed and forgot to charge it. It was at 40% when I woke up, and I'd venture to say that under normal usage, I could get another 4 hours out of it when it's at 40%.
I also have netarchys 4.1.9 kernel, and setcpu set to set the processor to 245 mhz when the screen is off.

Ok, so i tried completely wiping device cleared all cache and installed minimal apps. I will see how goes. The funny thing is that I took it off the charger around 5pm and when I looked at my battery status it says it's only been 53miin since unplugged and I'm already down to 68% of battery left. what's the deal? Maybe I have a bum battery already. Who knows. I'm going to drain it all the way down and see if that makes any diff.
EDIT: ok, I just realized that the timer reset after I rebooted my device. I forgot that it does that. Also I just wanted ton add that I did not do any type of restore from a backup program.

How is your signal strength where you are?? Having a weak signal will DESTROY your battery (trust me my battery goes down more than 10%/hr in a ****ty signal area but when I get to a good signal area it barely drops 3-4% (and this with bluetooth streaming music the whole hour)).

ok today I reflashed the phone, didn't install any apps, went to work, had my phone on airplane mode for a while because signal strength SUCKS at my job so it drains my battery very quickly, but I ended up getting only 10 hours out of the battery before I had to switch.
I didn't install ANYTHING and still the same results.
I'm convinced, the EVO just doesn't have great battery life that people claim, it's decent for a smartphone, but nothing spectacular AT ALL!

yeah, I'll read where someone says "I get 48 hours with moderate use!" but when you find out what they did, a couple of THREE MINUTE PHONE CALLS and a few texts, MAYBE 5 minutes of web surfing, that's it. in 2 days that's all they did with their EVO - and then I think WTF IS THE POINT?!?!? Why would you spend 200 dollars on an EVO when you could have gotten a HERO for 30 bucks that does all those things you did in that 48 hours?

I agree, either
A) me, my fiancé, my cousin, my 3 friends with EVO's ALL have defective units
B) the people who claim "moderate" usage are REALLY only having extremely light, barely any usage
or
C) these people are just telling boldface lies.
I've said this before on sprintusers and people argued with me all day saying I'M lying, but when you look at their screen shots showing this type of time, I poke holes all through their arguments, I've seen one where the poster claimed to have made a total of 40 minutes of calls, but there was no indication of voice calls in his screen shot, and android system only took up about 18% of the battery with cell idle and standby taking up the bulk of the juice. That alone tells you that the phone isn't doing anything and isn't being used.

when I'm at work signal strength SUCKS, so I keep the phone on airplane mode
when I'm home however, signal strength fluctuates between 3 and full bars

First off grab baked snack or CM6 both these roms have given me the best battery life of all time, then grab juice defender and setcpu, make sure everything is wiped and you are not restoring any apps that might potentially eat your battery, set setcpu to 245 when screen is off and let juice defender set up its own settings.
Just with this i had my phone off a charger for 16 hours straight and am only now at 50% this is with regular use for me which means on average texting all day (i am 17 its what i do XD ) a few brief phone calls and maybe an hour worth of data/wifi usage
there must be an app doing this because i had the same problem as you on baked snack even until i wiped everything and started new.
Currently im running cm6 and during my first few hours of school i wont touch my phone at all and it will maybe...mayyyybe drop 4-5 percent
Hope this helped anyway

What sort of battery performance are people seeing?

So I've had my Defy a week and I like it, more than I thought I would to be honest.
However, one thing that's bugging me is the battery life.
In their review, Engadget actually highlighted the battery life as one of the big plus-points of the Defy.
They state:
Engadget said:
In our experience, the Defy seems to have stellar battery life, which is relatively hard to come by among Android phones. Not only we were able to consistently make it comfortably through an entire day on a charge, but we were surprised to find that after putting the phone away with about 75 percent charge, it was still on with 21 percent remaining two days later. Granted, it spent most of that time in WiFi calling range (which disables the cellular radio), but many smartphones give up the ghost from 100 percent charge in less time...
Click to expand...
Click to collapse
Now, I'm not using wi-fi calling but I don't think that should excuse or explain the fact that my phone barely lasts a day when at least one other handset has such significantly better battery life.
Anyway, I was just wondering how everyone else's Defys were performing.

Im coming from a vibrant and the battery on this is the best on android so far that i've ever used(g1, mytouch, mytouch 4, vibrant, etc.

If you don't mind me asking though, how long do you go between charges?
As I said, I'm lucky if I make it much more than a day - certainly two days isn't possible.
But I'm not a particularly heavy user, a bit of internet and a few texts here and there but very little in the way of calls, so I kind of feel like I should be getting more out of the handset.
When I check the battery usage, it's quite often ~40% each for 'Mobile Standby' and 'Phone Idle'.
So the vast majority of the drain is just from the phone being on, not from anything I'm actively doing.

Is this your first smartphone? =)
I go a day and a half or so. I'm heavy on web use and playing 'slice it' all day.
for my usage, im THRILLED to have a phone that can still have 30-40% at the end of a long day.

Just try to reboot the phone after fully charged and detached from power. There is an issue with the "suspend" process in some cases (not only on Froyo 2.2) which disappears after rebooting. Mine lasts 2-3 days with average use.
The issue at Google (I am not allowed to post links as a new user )
code.google.com/p/android/issues/detail?id=11126

I can use the web steady for 5 hours, this includes some streaming video, if I start at 100% its down to 10% by then. At work it lasts easily all day but it gets little web usage and maybe an hour of talking. I use battery booster and advanced task killer, my backlight is set at 70%.

With moderate use (some calls, lots of texts, some web browsing) I get 2 days. It needs to be charged at the end of day 2, but I'm happy with it. I don't have any ot the social networking crap on so it's not constantly syncing. I think that may have something to do with it. I keep my backlight way down too.

Battery life? i got defy just a week ago and first impressions are good. You know, in the first days you make yuor phone working a lot, testing all the features, trying new apps from the market (so internet connection always on) , watching some movies, playing 3d games!
So a really heavy use, but power lasts at least 1,5 days. So i think using the phone moderately makes the battery life easily up to 3 days.
Try some task-killer app, and then test the power duration. Some softwares stay in background and keep draining power.

No.
And I don't see what that's got to do with anything.
My battery life seems to be noticeably poorer than what the majority of people here are quoting.
If I were to use the web for 5 hours, there's no way I'd have anywhere near 30-40% of my battery left.

Having looked at your link, it sounds as though when that's happening, people can see the Suspend process listed in the break-down of what's using the battery.
I've never seen it listed, so I'm not sure that's the problem here.

I've got Spare Parts installed and it's set to 'aggressively' monitor and kill processes.
A friend recommended it over the likes of Advanced Task Killer because it's supposed to be better at differentiating between apps that are safe to kill and parts of the core software/system that could cause issues if closed.
I get what you're saying about using the phone more than normal because it's new but in the 8 days since I got it, I've spent 7 at work, so I haven't had that much scope to mess around with it.
I've switched the screen from automatic brightness control and I've disabled the background syncing for facebook, so hopefully that'll make a difference.
If not, since it's just over a week, I'm well inside the 28 days I can have it swapped for being faulty.

Quadrant: 1100 points, Linpack: 6,49 Mflops
Edit: ooops, should read the title more carefully next time.
My defy runs for about 40 hours on one battery charge.

i have to charge mine everyday at night after using it whole day, time to time. Not bad tbh.

A task killer is NOT necessary.
It seems like blur services are push rather than pull which uses much less battery (think blackberry). But im not 100%.
I've set up yahoo, corporate, facebook, and picasa just to test it out and it didn't make much difference in my battery life.
I consistently get a day and a half (unless i play games). Can push to 2 days if i put on airplane mode overnight.

Found this on a german forum, as you can see, he was not in flight mode. I guess my desire's battery won't last that long.

I can go about one full day with moderate/somewhat heavy usage. Won't last 2 full days though.

People keep saying that but I'm not convinced.
I mean, if I use my browser say and then finish using it and know I won't need it again for a while, why prevent me from actually closing/killing it?
It seems so ridiculously counter-intuitive.
Plus, if it's really not necessary, then why are so many of them being developed?
Even Samsung are producing task managers now for devices like the Galaxy Tab - if it really wasn't necessary, surely one of Google's top hardware partners would know that.

And samsung is so great at making stuff...? Touchwiz??
Also, samsung's task killer does not show inactive or background apps like most task killers do.
What is the harm in the browser being open? It uses no cpu+ this phone has more than enough ram that it doesn't need you to close apps to keep things running smoothly.
It also will not improve your battery if you arbitrarily close an app only to re-open it later and use more processes.
Just my 2 cents on this topic.

Something i already posted in a german forum about my battery life:
2,5h gaming (Zenonia),
3h mobile internet (ICQ, Yahoo-mail, web, market)
2h of activated WLAN and deactivated sleep to copy stuff from pc to Defy
1,5h music (radio)
and 1h (and 6 minutes lol) of phone calls
After that day, i still had 30% of battery.
The maximum i reached were 75 hours including MY normal use with some mobile internet, some texting and 1 or 2 calls...maybe an hour of gaming at most.
I did not charge it first when i got it, because the battery was at 80% already/still and i wanted to play around.
Current running time: 26 hours...i activate plane-mode at night from now on. Low 70s now.
Everything at minimum display brightness (30%?)

All the apps launched keep consuming RAM even if they're not in use. I brought back 106 mb last time i performed a task killing! In most of the cases less ram means worst performances / more work for cpu.

[Q] Terrible battery no matter what... anyone else?

I've had 3 or 4 different evo's and it's been almost impossible to receive decent battery life on almost any rom. It started with CM6 and I switched even though I loved it and went to Baked Snack or some other rom that stated battery life, but it just always ends up dropping on me no matter what. I thought my expectations were too high, I just recently got my last replacement and it's now 3-4 days old. I heard how CM7 and Miui's latest had excellent battery life so I couldn't wait to test them. I first tried CM7 and as long as it's on stand by or not being used the battery was pretty decent I guess. That's with Green Power free running btw. when I turn the phone on to start using it, the percentages just drop. Tried Miui after hearing how good the new battery life is and almost the same thing.
So, that led me to believe it was due to some program, but for the most part I keep these stock. One of the first things I setup are a Gmail account, FB account setup... then of course my apps are added automatically hardly any widgets ever run. If anything it's Buzzbox, I've got beautiful widget's clock now. I use Vlingo, not sure if it's a hog. When I check the battery stats, there's nothing crazy or out of the ordinary. Anyways... there's got to be something wrong, I'm guessing. I've got a regular battery and an extended battery and they both do terrible. I'm going to install a rom from scractch with nothing loaded at all and test the battery. I hate to do that, because testing will take awhile especially with adding one program/widget at a time to monitor the percentages lost.
Here's a list of apps I normally have on my evo and run occassionally:
Vlingo
Green Power Free
Juice Defender (before green power and GB)
handcent
buzzbox
facebook
Swype
Google Services
Voicemail
Are any of these battery abusers without me knowing it?
I normally keep wifi on and connect to it over the 3g data, although I believe Green Power said it cant control the data on the GB roms as of now.
Today, I started with 98% with my extended battery, CM7 and now at 1:00PM I'm at 70% Minimal usage.
Sorry for the long post.
Bluetooth is off most time and Wifi like I mentioned usually is on, because I heard it uses less power than mobile.
sorry for the long post.
Just looking for some assistance.

Restore it to stock.
Calibrate your battery.
Use it for a few days without installing all your apps. If the battery still sucks, then you are probably going places that do not have signal and the phone is searching a lot. Check About - Battery for time without signal.

It is a Seidio
Of course it's not as bad as the original, but watching the batter go down 10% while I'm using it is very disheartening. Awhile back, I was able to get decent battery life, but I can't remember what rom, it might have been Baked Snack like 1.6 lol, guessing anyway.

I have had my best luck with mikFroyo.
What is going on with google maps? I have the same problem wiht MikFroyo

I am one of the heaviest users around, I stream pandora for about 8 hours , listen to music app about 2 to 3, check facebook and certain websites constantly, my two email acounts check every five minutes, my brightness is at 100 percent, my gps and location services are on, I'm overclocked...using 4.3 mikfroyo with sbc number 7...at the moment I'm using miui with sbc 7 for aosp roms, depends what you do, but either way no matter what kernal or rom you use I'll tell you, this battery will last you all day, this battery changed my evo experience...
edit: I don't use setcpu for profiles, just for overclocking, i dont use juice defender, the useless task killer or anything
edit 2: Conductive i had the same problem update to 4.4 or 4.3

so let me get this straight, average use is 8 hours of pandora, 8 hours of sleep, and that leaves 8 hours for facebook and etc, so lets say 4 hours total for a guesstimate, leaving 4 hours of non activity of the phone being off. 20/24 hours is "average use". I mean this is not a competition of who uses theyre phone more, all im saying is that with this battery you can do pretty much whatever you want without caring with ANY rom or ANY kernal you want.

i just got my evo after a hero.
the battery life is exactly what i expected. ive got a stock sense, rooted with clockwork.
i dont use widgets, no auto syncs. i have complete control over my device and it never leaves my hand. that being typed, i can get about 13 hours of up time.
yes, id like the battery to last longer but im not willing to have a fatty evo for the 3500mAh battery. I purchased a second stock battery, official HTC, so if Im gonna have a long day, ill have a battery with me.

Ok, yesterday I loaded Miui with nothing additional except changing the LCD density to 200, green power (which is useless since wifi doesn't work with this kernel) and right now I'm at 14h, 49m since unplugged with 17% left (normal battery). That's with minimal to average use. I notice when I'm using it, I can watch the percentages just drop, so I guess it's functioning normally and it's due to just my usage and programs, I'm probably expecting too much from my battery, once again I guess. I'm going to try your rom next with my extended battery.

I know what stock battery users go through, and with heavy use they don’t last too long, but I’m now in a different, horrible place entirely and I have the 3500 mAh battery!
I know that something is clearly wrong with my Evo but no one seems to know what it is. As I said I’m also using a 3500 mAh battery, but not to any advantage. In fact I get considerably less usage with this now then I used to get with the stock 1500mAh battery, regardless of the ROM or kernel.
Current specs:
HTC EVO 4G, Hardware 0003
16GB Wintec Class10 MicroSD
SEIDIO 3500mAH Battery/Camera Protector
Calkulin's EViO 2 v1.7.7 (have run several different Sense and CM ROMs)
HTC kernel #15v7 (doesn’t matter, have tried stock and every TM, regular and SBC)
Quadrant ≈ 1365
Linpack ≈ 33.05 MFLOP
and…(drum-roll please)
Battery Life: 70% after 6 hours, literally next to no usage.
Before middle of last November, if I charged the phone fully (without the benefits of SBC), and then just unplugged it on a Saturday night and let it sit unused for like 19-hours, the charge would be around 89%, +/- 1%, with the stock battery. In that same scenario now the 3500 mAh battery would have shut the phone down long before 19-hours rolled around.
Yesterday, using the 3500 mAh extended battery, no phone calls, Bluetooth on for about 20-miutes this morning for the drive to work and was turned off upon my arrival, and I’ve sent and received 4-5 messages on GTalk. That’s it.
The current status:
Charge: 70%
5h 52min unplugged
Up time: 6:15
Awake time: 1:20
Battery Usage screen:
Cell Standby: 42%
Phone Idle: 43%
Android System: 8%
Bluetooth: 4%
Display: 3%
Phone runs great; everything works great, no other issues. It once fell about 10”-12” onto plush carpet (kitten attack). It was in the Sprint case with the stock battery then, and has not been dropped otherwise. If anything, I am ridiculously careful with it.
Something happened the middle of last November like a switch was flipped, and battery life has been horrible ever since. Since we got our Evos back in the very beginning of June, 2010, I don’t think that returning it to the Sprint Store was an option then or now.
No one seems to have seen anything like this or have any clue what the issue might be, but it was suggested that I RRU it back to original, update it to current and then test the battery usage. Then, basically just live with it and see if it helped. After that, I’ll re-root and get on with life, whether battery life is better or not.
Any constructive thoughts are welcome. Thank you for your time.
Note: my apologies is this constitues a thread hijacking; not my intention, just saw title of the thread and it sounds like my life.

Thank you for the input. I thought about that so I tried the 3500 mAh in my wife's stock Evo and it runs forever. I'm so envious! I've swapped her stock battery and mine and they both run the same in either phone.
In mine, the stock battery usage is proportional, too. Fully charged and unplugged at 6:00 AM and with absolutely zero usage, sleeping screen off the entire time, by around 2:00 PM the stock battery was at 41%. That was also with very minimal synching (I've tweaked those settings nicely), no bluetooth, etc. I believe that the awake time was like 36mins. Sick, but unfortunately not in a good way.
Since it can't hurt, I think that I may do the RUU thing this weekend and then re-root afterwards. It may not help, but its literally the only thing that I can think of that I haven't tried.
Again, thanks for your thoughts. Have a great day!

Sorry, I've bypassed your rom for so long, but I've got it loaded now. Looking forward to trying it out. I can't lie I love and miss CM7 and Miui, but if my battery seems to last longer with a sense rom, then I'll be switching. So far it is very snappy and quick. Do you recommend I stick with the stock kernel or switch to something else? Do you use any setcpu, juice defender, green power or anything?
Do you have theme's as well?
Updating a titanium backup for my apps now.
I'll post back how it goes. I would say I had the same problem as the user above, but this has happened on mutliple phones and roms.
I know with a new phone you need to cycle the battery quite a few times. Someone told me roms were similar, even though I never understood why. Would you say that's true? In order to give the rom time to adjust to the battery and settings you need to give it 3-5 days?

More Battery Testing on the SGS2, Stock batt VS Ankler

Hello forum and its inhabitats ! I have a new issue today (a new thread about it at least, the issue was here always); battery capacity and the SGS2 battery life ! My GS2 was sent with a 1650 chinise battery -- im not very happy with it. Using the phone quite passively leaves it with only 6 hours of battery life - i checked and it was roughly 20% per hour -.-
So i was browsing ebay and stubled on battery replacers for the GS2, one of them being a 2430 mAh capacity battery (http://item.mobileweb.ebay.de/viewitem?itemId=130594902895&index=14&nav=SEARCH&nid=15065655277).
So i wanted to ask, is it a fake ? Which battery should i buy to prolong my phone's life ? Thankyou for anwsers by time ^^
Sent from my GT-I9100 using XDA App

Oh and what i want is an extended battery without having to get a bigget case or anything. And, should i buy a 1650 again, just the japanese version ? Come on people i know you can anwser this
Sent from my GT-I9100 using XDA App

The Anker 1900mah battery (amazon.co.uk links: single battery, two batteries + charger) is probably the best extended battery which is the same size as stock (no bigger battery cover needed)

20% battery per hour is not normal with whatever "passive use" means. I would first investigate what's using up your juice before getting a new battery. Go into Settings -> About phone -> Battery use to see what's going on. Your phone might not be getting into deep sleep in which case BetterBatteryStats from the market might help you.

Yes its fake, only buy original samsung batteries, samsung has a larger 2000mah battery if you want more capacity.

Yeah, the screen usually eats 65% of the total battery. Where and what should i search in this betterbatterystats ? (downloaded it already).
And yeah, not quite passive use i'd say ^^
Sent from my GT-I9100 using XDA App

Well, if the device loses 20% per hour, its probably not going to sleep.
When looking at the battery stats (settings > about > battery), try to see if the device is awake a whole lot more than the screen is on.
If it does, with betterbatterystats you'll be able to see by going to "Partial wakelocks", whats the cause of it. if an app has a long wakelock time it is probably the issue for the battery troubles.
try to see if you have facebook sync, maybe its causing it as well.

Im gonna run System Monitor today, to watch what apps used what and how much. Plus BetterBatteryStats at the end of the day. Lets see whats wrong with this phone <.<
Im also using Revolution ROM (2.7.1 i think..) with the CF-Root kernel. What i turned on by myself is: screen brightness minimum, sync of Gmail and Twitter (quite often, twitter every 5 minutes and Gmail i dont know how much. Constantly i think). Gtalk is always on, Mobile data is always on too, i do some browsing at times and some games too (at a higher screen brightness usually). AVG antivirus is always on, Latency is updating my position, Evernote large widget (the only widget im using, everything else is shortcuts). And thats it.
I know it may seem much but i still think it shouldnt be eating THAT much. Especially when its screen is off for 4-5-6 hours per day because of school.
Im also gonna post the apps that shouldnt be running in the background this evening (im from germany)

Today's results:
-unplugged this morning at 7:33 - 100%
-plugged in right now at 16:23 -5%
So roughly my battery lives ~9 hours per day. Why im still not happy ? Because im not using it the half of the day due to school, and when i do use it, the discharging is a bit overwhelming in my opinion.
Turns out it drains 11%/h or so.
I'll post the numerous screens from different applications, hoping that peoplr will help me improve the battery (since i know a lot of other people have their phone living for 20 hours !)
Also, you will notice the skip in the stock battery monitor and in the system panel app, its just how i said in my other thread - data loss. I was reinstalling chainfire so that the tegra game would work, and ofcourse the phone rebooted forcefully after installing/upgrading the CF3D plugin.

None of the next ones should be running in the background in my opinion:
None of those eighter:
These too shouldnt be here ?

Those that are EX here i know they should be working.

Sorry guys for the overload of screenshots.

UPDATE: today my screen (when it was used) was at 20% brightness, and i deleted the twitter account, so no sync every 5 minutes (i still dunno about GMail, maybe its constant ?)
Also ! I dont think my screen really used just 48%, its usually more - around 60% ! And today i actually saw that it was 73% at some point but then it would fall down to 60 again due to idling (probably the data was lost. Again.)

if you are looking for a new battery, the anker 1900mah is the best you can get without increasing the size of the phone! It is also the only third party battery that is proven to be the mah they claim it has, some even get 2000mah with this battery.
If i was you, i would first disable all your widgets, and then check again! If its a big difference, add them one by one slowely! Some widgets can cause battery drain. If that doesnt help you can try to reset your whole phone back to how you got it in the beginning and then slowely add your apps back.
