You know mate with GB i never got more than 2.5 hrs of battery backup .! But with ICS im getting 4hrs+ battery backup and the screen brightness is set to 60% Which is great .!
[Galaxy S II General] ant987:
Wee I dind't use to get a great battery life too, but when I updated to 2.3.6 XILA2 and then XILA3 version, there was a huuuuuge improvement in smoothness and battery life! And since then I've never been able to find an ICS rom with the same result!

Whaaaat? How is possible 10+ hours of screen time? I can't believe it!

Don't know about everyone else but what's the point on a phone lasting 4 days if there's no usage? Show some screen times, that's the relevant part.
[Galaxy S II General] Pryltokig:
Yes, the wakelock is due to Endomondo... :)

I currently use the kernel that comes with NeatRomLite UHLPS (Siyah 3.3.2), but I'm thinking of upgrading that to 3.3.3d...but now everything is working so good for me, so I don't know..."If it ain't broke, don't fix it", sort of... :)

Damn, you guys get good battery out of your phones, I thought mine was good! I don't think that I could ever get out 6h of screen time out of my phone!

Edit: I saw now that the guy with the 6h screen time was running GB, that's just plain cheating! ;)

[Galaxy S II General] Zod5000:
I'm using stock ICS 4.04 LQ7. I rooted it. I removed most of the useless extra garbage with titanium backup. Then I installed setcpu which is running on default settings with 200mhz as min.

I think over the 5 days I used 2 hours of screen time. Mostly at 15-18% brightness (sometimes much higher if outside). My job entails using a computer so I don't use the phone alot during the day. Maybe to check my gmail and what not. Play some angry birds on the bus...

I never made it to 5 days before. GB 2.3.6 was the best I'd gotten at 4.5 days.. I had a really hard time getting to 4 with 4.0.3. It's good to see my phone isn't draining too much power.

Weird battery

I've got some weird battery related questions:

I am quite new to flashing and i just flashed cf-root and installed the supernexus rom and before that the f1 nexus rom from the same designer.

My battery life was quite amazing. 1.5 day and still 60%, then when doing some stuff on my phone: scrolling in whatsapp/listening music/watching a movie with mx player it just hangs.. only way to uncrash it is pulling out the battery. After pulling that in my battery shows 5% to 20% less battery..

flashed kernel: cf-root

rom: supernexus rom JB: 4.1 or F1 Galaxy Nexus 4.0 ICS.

I tried reflashing and clean flashing but doesnt solve it.

anyone knows why it just hangs out of nowhere and scews with my battery? ..

I know it is not the right forum but i have to get to 10 posts to post my problem.....-___-

Honestly when I was on 4.0.3 I didn't think setcpu helped that much.. maybe added 25% life span. On 4.0.3 I had a hard time getting to 3 days with min. use. Setcpu got me to almost 4. I think the 4.0.4 upgrade did the most.

I haven't really messed with the setcpu settings. I run the default settings that it comes with.
[Galaxy S II General] currway:
seriously how did you guys get days of usage. Even if i put the phone on 2G data , it could only last me 20 hours or so ...

i9100G

ReMICS ROM

Horsepower 215 - hotplug on low 150 mhz , max 1008 mhz.
[Galaxy S II General] currway:
OK folks , done a real life usage test scenario and here's my report.

Phone : i9100G

ROM : RemICS-UX 1.5.3 for i9100G

Kernel : Horsepower 2.1.5

Modem : DXLP6

CPU settings :

AbyssPlug Governor with min CPU 150 Mhz , max CPU 1008 Mhz.

Undervolted at :

1008 Mhz = 1100 mV

800 Mhz = 1000 mV

600 Mhz = 950 mV

300Mhz = 875 mV

150Mhz = 850 mV

I/O Scheduler : noop

Radio : Only 3G (up to HSPA 15) with data on ( no WiFi / bluetooth / GPS )

Syncing : Gmail , calendar sync. XDA app on 30 mins interval sync.

Screen brightness : Med Low.

Usage :

Started test on a fully charged standard battery, just when i went to bed.

During 7 Hours 35 mins of bed time for me, drainage of less than 1% per hour, so that's about 7% of batt gone over my bed time. I'd call this a healthy deep sleep, no issues.

Uses screen time to view facebook , news apps, browsers, whatsapp over the course of the day. As you can see from screenshot, my screen time is only 2 hours as opposed to 4/5/6 hours as posted by others on the forum. When using screen time , battery percentage drops pretty quickly - eg 10% gone over some 20 mins.

If i leave my phone idle with screen off on the desk, there's no problem with it going into deep sleep. It's able to maintain very little drainage ( avg less than 1 % per hour ) , which i'm happy for.

Summary:

- Out of the 15 H 41 Mins to get from fully charged to 2% , to be fair 7.5 Hours of it is practically my bed time. So to discount that , it just means i get only 8 Hours out of my phone when i'm out and about. Not happy here, looking for more than 12 H.

- There's no issues with phone getting into deep sleep , able to retain charge very well during deep sleep. Happy here.

- My issue with battery drainage is focused at screen time ( and also 3G modem usage time as it goes hand in hand ). Not happy here, looking for 5 hours of screen time.
[Galaxy S II General] kmetek:
why i'm getting ANDROID OS always 30-40% while you guys 10% max?
[Galaxy S II General] currway:
kmetek, there's no easy way out, you have to install betterbatterystats and cpu spy to monitor which process is hogging it up. Chances are the process is giving you partial / kernel wake lock hence unable to put your device to deep sleep to save battery charge when you're not using it.

http://xdaforums.com/showthread.php?t=1631433

A common cause of partial wakelock would be the AudioOut_1 which despite many has reported that it's due to keytones/lock sounds/touch key sounds , i myself find that it's not only due to that but more reason(s) than that which i still haven't found a reasonable answer to for ICS. AudioOut_1 is just one example, there could be many more reasons and i guess i would let you follow the leads from other forum topics rather than me digressing more in this thread.

[Galaxy S II General] mayzei:
Firstly, if you've not got it, install Bettbatterystats from the Play Store.

Then, have a look at the cpu states, if there really isn't any time in deep sleep (bottom of page), have a look in "kernel wakelocks" and then more importantly in "partial wakelocks", google any entries that you do not recognise or have a large amount of wakelocks (the numbers under the entries).

Hope this helps!

I'm doing a study with overnight battery drain on S2. I run 2 S2 in parallel. The latest 4.0.4 with standard kernel drain 3-4% per night (8-9 hours). With siyah kernel, after about 1 week of training I got 1% drain per night, same conditions no data. Results aren't definitive because I don't get always the same results from siyah. Sometmes it drains 2-3% also.

With screen on time, meaning daily usage, results vary. My acceptance is 48h with 2h+ screen time. I'm running these tests for about a year an d best results came with 4.0.3 XXLPG and 4..0.4 XWLPI. results aren't definitive.

from the screenshots I attached below, does my alarm clock eat the most battery??

because I always turn my alarm on, I almost never turn it off..

any feedback will be appreciated..
[Galaxy S II General] currway:
AlarmManager is a system process that is used by apps to keep the phone awake so that the app could finish what it wanted to do, without the danger of the phone stopping its work.

Simply speaking, AlarmManager has nothing to do with your alarm clock that wakes you up every morning.

does anybody here use auto memory optimizer??does it improve battery life...I have been using it for past 1 month but I just dont get it weather its really helping or not ;)...
[Galaxy S II General] iovaniorgovan:
generally speaking, you get more hours of screen on time if start using your phone right after unplugging.. Modified kernels reduce the brightness more than stock, reduce the cpu and gpu freq so you get less battery drain and lesa performance when not needed. I find reduced brightness a pain when outside in the sun, those moments until maximum brightness kicks in fell so long.

You shouldn't need extra ram management on s2, it has plenty of ram.
