Battery Life - AT&T Samsung Galaxy S II Skyrocket SGH-I727

I let my phone charge all night. I unplugged my phone at 6:46am it was 100% I used it non stop till 9:00am and it's at 36% battery
Does it seem normal to go that fast?

When you go to battery under settings, what is chewing up your battery?
Also, if battery is your issue - I recommend Instigators Kernel with smart ass/badass scripts.
I left my house at 9 am this morning and I still have 40% battery with GPS usage and moderate phone/web usage...

Charged 100% again
Phone has been on battery for
3:23minutes and it's at 32% now
Screen is 49%
Browser is 25%
System is 8%
XDA is 5%
I'm still a noob with all the flashing stuff but I will try it I guess.

Also, some of the forums suggest you recalibrate your battery when you flash a new rom... It wipes the battery stats and starts from ground zero. The app is in the play store Battery Calibration. Just charge to 100% and run this app it will do the rest. Don't think that is your problem, but it will give you accurate stats about your battery...
Here is the thread for the Instigator Kernel. If you flash you phone on a nightly basis, you will have to reflash this each time you update on a nightly...
http://forum.xda-developers.com/showthread.php?t=1721235
Another good program to run is CPU spy like I said. It will show you what your CPU's are spending all their time on. Once you get the new kernel flashed, just run that program. You should see more time being spent at the 192 Mhz range or the deep sleep when the phone is on stand-by...
Good luck with it!

That is a little fast, but he did say he's using the device non-stop for 3 hrs on 4g. 4g uses a lot of battery, and 3 hrs of "non-stop" 4g usage doesn't seem that unreasonable. The question is, what does "non-stop" mean to him? Screen on with 4g data being transferred for 3+ hrs strait sounds like it would kill a battery to me!

I agree it is fast. I am not sure if he is on LTE or standard 4G... LTE would drain it if he is in a bad location... There are a lot of factors.... I am sure his huge screen being on has a lot to do with it. Brightness level??? Signal Strength??? ETC...
CM9 is known to be a little bit of a battery hog in the wrong situations... That's why I suggest a kernel that is aimed at GOOD battery life...
But do whatcha want...

Where I am I don't get real good service on Cm9 it says 4G and sometimes it's just H with 1 to 2 signal bars also my display brightness is set to automatic
I downloaded and flashed the instigator + badass I will see if that helps also got the battery calibration will charge and reset it
Also I read about nexus extended battery so I ordered one of those
thanks you all for the help
Sent from my SAMSUNG-SGH-I727 using xda premium

Yeah, H means HSPA+. Good glad you got the Instigator Kernel.
With poor service, your battery will drain like a leaky paper sack..
Hit Thanks if I helped you along your way!

I sincerely recommend you give a try to sky ics either base. If you choose stock get rid of the bloat. Sean's kernel. I am getting 13 hrs to 22hrs which I did not believe was possible now I have three batteries 2 OEM and one extended and I feel I don't need extra batteries anymore

Besides the previous post regarding sky ics for battery life I have something I want to share with the forum is that I use external charger and in my last charge I am not getting any wake locks I may be wrong but look at my latest battery use

I'm sure most people have seen my results.
That's on CyanogenMod 7.0.2 with the LorDmod 4.4.2 VrIO kernel and Pinky Ultra Undervolt script. I've used CM7.0.3 and GingerBeast with various other LorDmod kernels and gotten very similar results, typically give or take a few hours.
Battery graphs without details are pretty pointless. Not hard to get a couple days out of it if you never use the phone.

No point in using wifi, I have GPS turned off as well. Minimal screen usage is my average usage but really, if someone can't figure out that a massive screen is the biggest battery hog on this thing then they should return it.
Can't screenshot ATM, but I have 91 percent battery remaining after 2 hrs and 50 mins. I have used the phone for texting all day so far (~80 messages while on battery) and my screen is consuming 74% of my battery, though nothing else is really running in the background. SetCPU 1017/245 with smartass governor is currently keeping my undervolted when asleep. My ROM is Inspired Ace by gtg465x running the latest stock ATT radio (Ace_Cingular_US_1.84.502.11-Radio-26_06_06 _30_M). I just ran the battery calibration listed here and am still working on eliminating the cpu intense processes as described.

LOL!!! Wow that is some awesome battery life you're getting on your GingerBeast ROM.
I think what dilli is trying to tell us is these types of threads have minimal value. Everyone uses their phone differently and the battery life is impacted greatly by this. If Joe Blow gets 3 days battery life out of SuperDuper v3.0 ROM paired up with the BestBatteryEver v2.5 kernel doesn't mean I will get anywhere near the same results.

This.
If you turn off your wifi and screen, Then its just similar to keeping your PC on sleep mode.
At the end of the day, battery should last through the day if you dont have a charger within reach. Again depends on usage.

The display on my inspire is what murders my battery. I mean seriously, if it is pulling 70%+ of your total battery usage, how much life can you expect with screen on for games, videos, browsing, etc. 9 hrs and 5 mins and 76% left. I have my phone locked to 2g networks when not using data, btw. that seemed to help. screen has been on roughly 30% of this time as I lock when not in use (between texts, as I text my gf all day usually )
I bet most of the folks here didn't use a Captivate by any chance... Use it, and u'll love the battery here.

Yeah, I've been getting erratic battery behavior with mine. I don't have it rooted or anything but there will be days where the phone will be idol for 4 hours during work, and it'll be down to 60%.
I always keep the wifi off and syncing off too.
With all syncs on.WiFi on average use(20-30 mins Facebook per day, 10-20 emails, 10-20 text, a few calls,etc.)

Anyone else think this is decent battery life?

Dunno, I hear battery complaints all the time. honestly imo its pretty decent. Or is this not that good?

At first after updating to Gingerbread, I thought it was draining faster, but I guess the battery adjusted to the new OS.

New personal battery whore record

It's well known I like to be a battery whore, my previous record was a little over 48 hours on a full charge with my Infuse. Today I beat my old record by about....20 hrs!
All notifications off except Gmail. 3g data turned off for about 80% of the time. Wifi on but set to turn off when phone sleeps. I did use the phone, text, talk, surf, etc. Probably would be considered light usage though.

I never use notifications, never will. This is my normal usage pattern. As I said in the OP, I do use the phone.
Get rooted and remove blot wear
Best way in some sense to get great battery life is get rooted, use Excellent Roms that removes all bloatware and find any apps that are continually running in background and remove them. (Tip) Get titanium backup and backup your apps then remove them but if you need later then reinstall them for future use. Just a few things to mention, so much more to add to save battery. I suggest you just use your phone and try and save in other ways that will extend you daily use.
How much screen on time? That's generally the best measure of battery life, because if your screen isn't on, you're not really using your phone. And a percent usage tells nothing.
My infuse is currently going on 12 days, 14 hours, 16 minutes, 7 seconds since last unplugged with 1 hour 28 minutes of screen on time. That being said, it's because I use it purely as a backup alarm clock without a sim card now that I have my Note, haha. And no, I'm not going to go to the hassle of rooting, downloading a screenshot app, then waiting another 12-14 days to prove it. Just goes to show that battery life doesn't mean much without usage.

Hi all,
I just cant reach 2h+ whit my anker battery running aokp rom but it has been like this on any rom ? I do medium usage but still dissapointed tried every calibration method out there ! Is my battery dying ?
And also my battery is reading wrong it shows wrong % like when i reach about 25% all of a sudden either it shuts down either it indicates 1% remaining ? Saw quite alot of threads on this but couldn't find a fix...

The sudden discharge of the battery could possibly indicate A issue with the battery itself. If it's new I would defiantly ask the seller for a replacement. I have Anker myself And It's never discharged like that before. I'd look into trying a replacement and see if that helps your issue! Best of luck.hopefully a new battery will fix the problem.

i used AOKP rom before and it has battery drain problem, maybe that causes the problem?
AOKP link
try with other ROM and see?
AOKP does cause more battery drain in my opinion but the battery dropping percentage so drastically or discharging isn't normal. I would defiantly look into getting a replacement battery. Anker has been a good battery for me. They should honor the return and if its new, replace it. Best of luck

Sent from my Sensation using xda app-developers app
you probably just have a defective battery, from the pics and what youre telling us (happens on every rom). what mAh do you get on a full charge? I have an Anker as well and it doesnt drain quite as fast as yours, even when I was on AOKP I would get around 13-14 hours light/moderate use. try another battery or see if you can get a replacement Anker from the seller you got it from. but from my experience, the Sensation in general doesnt have great battery life. my MT4G on the other hand...I could easily see 20+ hours
I´ve bougth a new Anker and used it until my Sensation turned off.
No Calibration, because it is crap to do it manually and just make it worst!
Then full charge it (better while Sensa is turned off) and you will reach about a day and 5 or 6 hours on moderate usage (2-3hours screen on).
After 4-5 charge cycles you´ll get about 1 day and 17 hours.
If not, you should listen to the others above and send it back.
Hey,
How good is the Anker battery compared to stock battery? Does it really last 25% longer?
Well it's definitely better then stock however I remember I used to reach the 3h mark screen on time, but if you guys talking about stanby it's okay I guess I can get up to 16-22 hours

Although I have a P6210, so no 3G, but WIFI always on, 7 hours with browsing (mostly reading articles), on stock HC 3.2.
I didn't understand why the power lasts only ~5.5 hours while browsing and found out that Opera Mobile consumes much power.
Now, using Opera Mini, it lasts ~1.5 hours longer. I know it's uglier but for reading, it's perfect.

You should first check what is eating your battery (where you check your screen uptime). Or use cpuinfo for cpu deep sleep and betterbatterystats for processes or wakelocks. There must be something eating your battery.
Those guys with the much better battery life are probably P6210 users or P6200 without mobile data enabled all the time.
Probably

I will if i have time. But to give you a hint... It'll probably drain faster than normal. Common issue on all devices. Even iOS.
Exactly.
It will drain much faster, coz apps like Gmail will constantly try to sync.
But since I got free mobile data connection, I don't care.
3% off from watching a 20min video at Auto Brightness in a dark room, without mobile data & wifi on. 1% off on a 4~5hr. standy without mobile data & wifi on. I have not yet had the "full charge" in a while, which is charging only after the battery level hits below 20% or less. I have always charged at around 70~90% because it was advisable to charge it without letting the battery level being too low.

This completely opposes the video I just watched from YouTube on how to improve battery life. The video tells us that you should completely drain your battle once or twice a month .. which I can't see why so. I believe that only applies to the technology of batteries in the past

Exactly. The info in the video you watched is outdated and actually harmful to modern batteries. Heat is the killer of all Lithium composition batteries.

I always used my tab for fast revision (student) and browsing through wifi with about only half an hour of game. Here is my screenshot.
I have prob of getting into deep sleep, but one day suddenly i can get into deep sleep and my battery lasted quite long. Anyone know how i cn get into deep sleep? I've always clear my multitasking and ram before screen off.

The might be some apps hindering your phone to go into deep sleep.
How long is the screen on? Can you click on display when you go to battery stats again and look

Big improvement of battery screen on performance,
I'm now on my 10th hour after being fully charged.
I had wifi on all the time
2g mobile setting only.
Brightness on mid
Was able to use the phone on with wifi , gaming, doenloading, surfing for 5:30 min and still has 3% left
Much better from my batt life before which could only handle 4hrs avg of screen on
What I did: downloaded setcpu and undedclocked some apps using profile,
It doesn't lag at all even fruit ninja . Because our phone is using dual core, we don't need entire processing speed to use the web of play some games , so when I underclocked
Min 200 , 500 on some apps
Max 800, 1000mhz some apps
Nothing changed , there are no lags or delays whatsoever

Ps : I don't have problems with stand by batt time, this post is supposed to be regarding about how to prolong screen on usage
