Hi everyone.
I guess something is wrong in my settings or I don't understand this.
When I go to battery status I see there 83% remaining - 4h and half on battery. But the strange one is Display usage is 40% (highest). This is way to much. I barely use phone for stuff for like 15-20minutes max in last 4h and half. Brightness is set to 15%.
What do I do wrong?

What you mean? You can't get much more than 4-5 hours of screen time with you device.

No. He means out of 4.5 hrs uptime, battery stats are telling him he's had screen on for ~2 hrs of that, but he says he's only had the screen on for 15-20 mins.
OP - Forget about the % for screen on, what does it say for 'time on' when you press 'screen' in battery settings ? For example, my uptime is 2H 23M, my screen % is 36% (which would work out at ~50 mins) which is inaccurate as I've hardly had the screen on in that 2 & a bit hrs, but when I check 'screen on' it is accurate @ 4M 16S.

40% display usage from battery when I barely used phone in last 4h and half? Screen locked. Doesn't seems strange to you?

There you go. That's accurate. Obviously a bug of some sort/poor coding in Samsung's rom (or maybe even Google's code) that causes a reporting discrepancy. Mystery solved.
oh, I see.
40 % of the battery usage it was causes by the screen....if you were at 100 % and now it's 90 % battery usage would be 10 %. Screen took 40% of the drain so it caused 4 % of the overall drain, with 90 % left to drain that is.

I hope it's only a visual bug or sort of and not really "eating" my battery that much.

Gaston's explanation is better. Using his maths, your uptime is 270 mins, 17 % is how much battery you've used (17% of 270 = 45.9) & screen time is 40 % of that (0.4* 45.9 = 18M 36 S). Probably not absolutely exact, but close enough. Battery stats are an approximation at best anyways (as clarified by Google).

During regular use I am at 816 Max and 216 Min. When charging I use 1000 Max and 1000 Min. Screen off 216 Max and 216 Min. Battery life is alright, from 100% to 80% it decreases rapidly but from 79 to around 5% it is phenomenal. My phone will last around 12 hours of heavy use. I send a lot of texts 150+ a day and check facebook mobile about 5 times an hour.
Don't tell me to calibrate my battery, i've done it probably 100 times.
The objective of this thread is simply to see what other SetCPU profiles other people might be using.
from higher priority to lower...
Screen Off: 456-216
Charging: 608-216
Battery<10%: 456-216
Battery<30%: 608-216
Keeping 1000-1000 while charging is bad idea.
ideally power consumption should be none while charging so that battery can charge faster. I would suggest you to switch to the lower frequency while charging.
also, the 'Screen off' profile takes over if screen is off during charging thus giving you best of both world in case if you want to use fone while charging...(just set priority highest on screen off'
also, i have set battery = power saving mode settings.... through custom mode and also added peak off hours when i generally sleep
this lasts me more than 30hours on general usage and a day if i game and play music alot.
Brightness is set to auto all the times. although my usage environment never requires it to be above 40%

I just use the 608 max, 216 min for screen off and then a 456 max, 216 min for hours that I regularly am sleeping.
Does anyone know why we can only use certain seemingly random numbers? I would like to get much more fine tuned than differences of only ~150... And why is 216 the only min?? That's too high!

yes but 2nd last priority should be battery<10% (you have kept both at battery<30%)
My profile is that I uninstalled setcpu... I don't think it made any positive difference at all in battery life. I have switched to performance mode (phone charges at night) and I have been happy with the battery life. Other day 8 hour road trip with Slacker on for 6.5 hrs and screen locked on the whole time so I could flip around songs. Also exchange/email sync, news reader updates every two hours and some phone calls. I plugged in usb for maybe 3/4 hour to charge. At the end of day (took off charge at 6am and put back on charge at 1am) had 40% left. Biggest things for me to improve battery was get rid of running programs (setcpu/cache mate/etc) Also have the android task manager turn off some things when screen is dark and took email/exchange off push (sync every half hour)
Imho..
To all SGS2 owners,
Can you tell me how long this device last, generally use and talk time?
Some sites indicate it has 8 hrs talk time but others such AT&T itself, BestBuy, Costco do say it only has 3 hrs talk time.
So is it only 3 hrs?
on OEM battery: 10 hr and 30 minutes today and still at 74% medium usage
as for talk time i dont talk for hours and hours so i dont know lol but i can make all the calls i need and have plenty of juice.. i recommend using a cutom ROM like unnamed to save battery
on the extended 3500 battery: i got 41 hr and 30 minutes and i was at 19%
62% left after what I consider heavy use. E-mail, GPS, Wifi always on. It's a work phone so multiple calls during the day.
I'm using Unnamed ROM and even updated the ROM today to the latest version on battery. (hence the dip in the graph )

This device gets excellent battery life, especially after you root and freeze useless apps. Alternatively, just install UnNamed ROM.
Mine is bone stock with nothing more then Juice Defender. Tons of app's Medium use my best is 2 days 1 hours and change. Heavy use, Streaming 4-5 hours, lots of talk time and text with surfing with mail was my worst at 10 hours 48 min.
I am VERY happy with the battery life!
my phone is usually dead within 8-10 hours.. light usages in my view..
Alls i can say is that i went from 100-0 in 6-8 hours stock rom to 24-30 hours + with unamed rom... cant thank gtg enough

That is because you phone is awake 80% of the time according to your screenshot. If you want to improve battery life, look for the app that is causing it to stay awake.

You get only 8 hours because your phone never goes into deep sleep.. It is awake most of the time.. You may want to look into that..

Battery life is so dependent on your usage that almost all comparisons are worthless. I have learned its best to just make sure everything is running as efficiently as possible.
Surprising how some are getting a days worth on the battery.. I'm lucky to get 14 hours..
I can go 8 hours tool its dead or 14 with life to spare. It usually depends on how bored I am at work.
That's why I said its almost too subjective to compare.

You can also try using Screen Filter, add it as a Widget set to 75% for normal use, then another Widget set to 25-30% for night time use. One press on either Widget will turn it off, I only have to do this in full sun.

Yep. That was it. Didn't remember setting it to smartassv2. Oh well live and learn.
Its much better now, but im still not getting the battery life id hoped for. Approx 2.5 hours of screen on time. Drains about 7% per hour when sleeping

Ouch, 7% per hour in standby? Mine only drains 1% per hour. Goes up to 3% if the "charge wakelock" issue pops up.
The first long test I ran when using Screen Filter @ 75% I drained to 5% and had 4 hours of screen time. I think my total run time was 15-16 hours.

Yep just confirmed had 94%. Reported to ensure deep sleep. Woke up 5.5 hours later and had 74 % remaining. So more like 4% per hour but that's still too much. Wtf????

My battery graph goes a bit like this.
As you can see, the first green segment is the normal drain rate while my phone is in deep sleep. Say, if I restart the phone, and just leave it to sleep without touching it, the graph would go down at this rate. This rate is pretty good for me, usually a 1% can last 4 hours.
The blue segment is the drain rate while browsing with wifi. The drawing is only an approximate illustration, but needless to say this drain rate is much faster than the green drain rate. I can get 5 hours with wifi browsing, with equates to 1% every 3 minutes. It's not too bad I think.
The problem here is, after browsing (or doing anything) over wifi, the battery curve would go weird. When I'm done with browsing, I always turn wifi off. What I would expect was that the battery curve would immediately return to the normal deep sleep drain - the green line. And yes it should, because as CPUSpy shows, the phone deep sleeps perfectly. But the graph, instead, shows something of a "transition" curve - the red one as shown in the illustration. The drain in this period isn't as fast as the wifi rate (blue), but it is faster than than normal deep sleep drain (green). Only after some time will it return to the green rate.
So...what is causing that red curve?
Did you check for wakelocks using betterbatterystats?

Yes I did, but I thought having a wakelock would take away from deep sleep time? I usually wipe my CPUSpy stats and leave the phone to sleep for an hour, it would almost always come up as 99% deep sleep. But anyway, I did check again, and RILJ was at the top of partial wakelocks, at 16 mins after 16h. It isn't seem to be adding time though.
Why two threads within half an hour ? They're essentially about the same thing. You could easily have edited your OP and/or title in the thread you created ~26 mins before this one :-/

Dunno why CPUspy is reporting wrong, but the rilj wakelock was for long, hence the battery drained more. If you're looking for a solution, what I've read to solve that wakelock is to turn airplane mode, switch off mobile, switch it on and then turn airplane mode off....

The battery drain during usage is within the normal, but in standby it is too high, which I do not understand!

Using the battery app see what app or service is keeping your phone awake. That would be my guess as to what the problem is. I would also suggest flashing cpalmers kernel as well, which has been really good for me in limiting awake time.

Install BatteryGuru, give it a couple days to learn how you use your phone, and watch how it saves your battery once the learning period is done. I swear by this app, it brought me from almost a day to about a day and a half as far as battery life is concerned.
I installed the Gsam battery, it shows that "phone radio" was sucking down a vast majority of the battery.

Then you must be in an area where service isn't good and your phone is searching for service which kills the battery quickly. To conserve battery turn on air plan mode and then turn service on when you get into a zone with better coverage. This will help your battery a lot.

My opinion..don't install any more apps than what you only use. You install more apps it will obviously suck more battery. What you do. Root/unlocked the bootloader and install a sense 5 4.1.2 base Rom. I came from stock and since I've installed a sense 5 stock Rom I've notice a big battery saver comparing from the original sense 4+ stock.hopefully that helps.
Thanks all
Strangely none of this helped the battery drain is too high in standby, after resting (no apps installed only stoke apps) and even flashing sense 5 rom still 15% per hour and even in Air plan mode . The strange thing during the use of the phone the drain is normal.
