[AT&T Samsung Galaxy S II Skyrocket SGH-I727] eghoti1:
updated to 6.9.2, did a claibration, full drain, full recharge. Phone went through 2.5 days battery life with normal use with no SIM card in but GPS, WIFI, Bluetooth, Autosync all on. I couldn't kill the battery if i tried. Now I stick in my SIM and my battery drops 5% in the 1st half hour with just data (4G only, no LTE) and sync on, but no GPS, Bluetooth or WIFI. I am guessing using the radio for data makes the difference. anyone else notice similar affects?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] y2whisper:
Yeah Im trying to figure out what it could be.

Some theories (for me at least) are;

Radio related (battery drain is less on wifi. on hspa i can see the % dropping by the minute)

Battery related - I have two and my new one seems to out perform the old one, but its a very small sample size

Something else......
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] eghoti1:
yes.

I am leaning to radio related but to do a real time comparison, I am going to see what the drain is when changing the variable to packet data off and wifi on. If that's what it is I don't mind since I have wifi access through most of the day, but the drain with 4G seems pretty outlandish compared to wifi from what I can tell.

Does anyone know a way I could apply seans Swype theme to the newer version of Swype that I'm using (3.26 beta)? I feel the functionality of the new version is much better but I really like the ics skin... Thanks in advance!

http://xdaforums.com/showthread.php?t=1428530

no i don't know if any of these scripts are actually working as the boot time is pretty quick which I would think shouldn't be the case as it clears caches. but I am on "4G" right now and the rapid drain seems to be gone. again very small sample size i have only been testing this for a couple of min. I am just wondering if some kind of script runs on reboot with this rom that needs to go away.

again small sample size could end up being a placebo effect. What i do know is on the weekend my battery was performing better than its ever did. felt like i had a new device.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] eghoti1:
great thanks for the tip, I am on the 6.9.2 ROM, I forget which kernel that came with, Faux or Romracers. Faux right? Would like to try if you seem to experience a difference, plus we can add to the sample size then.

EDIT: I see I have romracers. I will report back after some further tests. thanks

I've wiped a couple of times now and reinstalled ROM but battery percentage stays at 100% until I reboot my phone. Any idea why?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] onearmedscissor:
Would it help battery life to flash a different radio?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] eghoti1:
i would think so. I am running KJ2 which from the skyrocket radio thread, users report better battery life anyway. So I'm not sure if any current radio available would make much difference.

update on wifi testing. I recharged back to 100% and calibrated battery. I have been on wifi/no packet data for last hour and 20 min with normal use. Lost 4%. So wifi definitely seems to drain less. Tonight I am going to try the kernel script cleaner and reflash romracer kernel

Is there away to disable the volume rocker (both up and down) from turning on my screen? I'm using the ICS launcher on this rom. Can't find a settings section to turn that off.

Thanks!
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] onearmedscissor:
Thanks for the response. Yeah my friend who doesn't use his skyrocket much got 2 days 16 hours battery with 25% left and he was on wifi the entire time. He only had the screen on for like an hour and a half though haha, but he used had packet data on for a significant time too. Hes using sky ics 6.8. Do you think changing network to gsm hspa only would help at all? I don't live in an lte area anyway. The only problem is the mode will reset every time I toggle mobile data off and on...

It seems like the main drain for me is the display, even though I have it set to adjust power automatically and I try to keep it around 15 to 20 percent brightness. Is there anything I can do to help make it drain less? Usually I'm just reading text, not watching videos or playing games or anything.

Here's an example. I was on 15 percent brightness almost the whole time too. The display was on for 1 hour 48 minutes. I even tried turning on flight mode for about 39 minutes but it seemed to drain at the same rate from what I could tell...
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] eghoti1:
Sure. Going back and forth between wifi and data i think I would get about a little over a day which i would be happy with cause my Infuse would last 5 hours no matter what I did. I also only have GSM/HSPA only toggled in the settings as I am not currently in a LTE market at the moment. There are a number of Power Control widgets on the market that have a data on off widget you could put on the homescreen.

I also have it on auto bright and the display seems to take most of my battery use averaging at 47%. CPU spy shows the phone rarely goes into a deep sleep, which I am thinking is attributed to BLN, but that being active is a must for me. At this point I don't know what else to do to minimize drain except keep stuff like BT, GPS Wifi (when not needed) off. Also freeze or uninstall any running apps you don't need. I am going to try the kernel cleaner tonight and see if it makes a difference.

[AT&T Samsung Galaxy S II Skyrocket SGH-I727] eghoti1:
well curiousity got to me. I did a cache & davlik wipe, flashed the kernel cleaner and reflashed romracer kernel. Looks about the same for the drain. 5% in 30 min.

[AT&T Samsung Galaxy S II Skyrocket SGH-I727] eghoti1:
I haven't flashed any radios on this phone. It looks like there are a limited number of radios for the skyrocket and I read through the radio thread. The one I have, kj2, has the best battery life consensus. But if you decide to let me know which one you do and the results.

I installed juice defender but its so tedious in its settings to make it effective for me. I use google voice for texts so my data or wifi always needs to be on even when idle.

Question ....

For those with weird drain.

What kernel are u using?

Any battery savers?

What does OS Monitor show as highest CPU use?

Have u flashed any 2.3.6 ROMs without returning to stock before this ROM?

Trying to track it down when I don't have it ain't easy.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] eghoti1:
just to document:

Romracer's Kernel

No Battery Saver (need constant data, whether wifi or packet)

Display is highest at around mid-40%

Flashed 2.3.5/2.3.6 ROMs (varying Sky ICS versions)

How do you get bln to work?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] onearmedscissor:
Has anyone tried the app, "screen filter," to reduce the amount of battery the display uses? It just shades your screen to various levels of black I think. Do you think it could significantly affect how much power the screen uses? Or is it basically that screen just requires a lot of battery regardless of how bright it is?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Danielk425:
I've never tried it, but I will now, thanks for the suggestion.

Does anyone know if haptic feedback significantly affeCts battery life? I did a search but got conflicting results. Would setting it to a lower intensity vibration change anything or is it more of an all our nothing type thing?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] appdroid:
What did you re-flash??? Next time when you have problem just make sure you include details it helps us to narrow down the problem.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] onearmedscissor:
I don't know if my drain is weird or if the display on this phone normally just drains a lot of battery but I'm using faux kernel 9u v2 on default settings, juice defender ultimate, and the newest sky ics. Also using v6 supercharger v9 rc4 on 1000 team settings and go launcher ex.

highest cpu usage is Android system at 31 percent, then Swype at 9 percent. My display is showing 60 percent battery usage at 4 hours 20 minutes on time with mostly low brightness and a little higher brightness. Is that normal for the display to use that much or is it a lot?

I never return to stock but I just formatted my internal sd	a couple days ago and factory reset.I used a few t mobile s2 roms until about a month ago when I switched to sky ics. I've also flashed most of the various skyrocket kernels starting at dag, then stockish, then faux and went back and forth a few times, but I always make sure to wipe cache, dalvik, and fix permissions in ROM manager. I don't think I've ever even used a 2.3.6 ROM. I also have maybe about 20 to 30 of the apps that come with this rom frozen with bloat freezer free. I'm also not in an lte area.

Sorry for such a long post haha. if you have any helpful ideas, thanks in advance. I'll add 2 of my battery screen shots in case it helps any

First yay Canada! :)

I used screen filter and noticed a bit of a lag. Seems that the app keeps running to hold the settings.

Still investigating battery life. Thought it was a mismatch with lib files when I flash radio. But the weird thing is when I reflash the dates on the lib files that are being pushed match the others in the folder. Hmmmm.

[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Uncle Irish:
Thanks

Looks like yours is pretty much default config from the ROM. Have you only flashed SKY ROMs or an actual 2.3.6 ROM?

How many days have you had the ROM installed with no updates or mods? Normally takes a few days for things to fall in place. Thats when you see more accurate battery results

Thx

Are you overclocking at all with Faux's kernel?

Android System at %31 is too high. Mine rides about %5 - %7

Your display at 4+ hrs is great, it's going to always be the highest point of drain though.

If there are apps you simply don't use, you can uninstall them instead of freezing them. Just some advise.. I trimmed almost 90mb from the ROM before I even flashed it.

I'm using GoLauncher also. It's a RAM hog but easy on the battery

Yours looks like good battery life. What are the big drops when it drains fast in your pics though? Is that gaming, videos or something else?

The main thing I am trying to find out is if there is something weird from bouncing between 2.3.6 ROMs and then back to 2.3.5 ROMs. Maybe there is something going on between the AT&T and Rogers versions. I guess my thoughs are if you have any sort of drain while charging or excessive battery drain in other ways, go back to completely stock, wipey wipey, format both internal and external cards and start from ground zero with ONLY the latest SKY ICS. I really don't care what my flash counter shows (63 if you're interested). I said in an earlier post a couple/few days ago that if I can get 10 hours out of my phone, I'm beyond happy. I beat it like Mike Vick's dog, so 10hrs is killer IMO.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] eghoti1:
Yes I'd say it is pretty default for this ROM. I've only flashed Sky ICS ROMs back starting with v6.3 I think. For update to 6.9.2 which was my last mod, it's been 3 days so it still may settle.

I agree if I can consistently get 9-10 hours from this phone I will be happy. My Infuse would barely last 5-6 hours no matter what I turned on or off and that was with a custom kernel and ROM. For whatever reason, Wifi plays so nice with this ROM and if that what it takes to get it to last extra long, I can oblige. I was just shocked at the dropoff in battery life when using 4G data only.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Uncle Irish:
9-10 hours should be about the norm for this phone. If you're getting crazy life like 1 day+, then you're definitely not using it to the full potential.

I see a lot of people using calibration apps and methods to calibrate the battery. It won't do much. I used to refer ppl to http://batteryuniversity.com but this link might bee more relevant. http://arstechnica.com/gadgets/news...-is-the-best-way-to-use-an-li-ion-battery.ars

I don't charge mine overnight

If it drains to %57, I charge it some.. same for any percentage. Just charge it some, no need to go to a full charge.

BatteryStats clearing won't do much either. Just forces the phone to re-read what it interprets the battery levels to be. Only the battery knows the exact amount left. It's best to use the recommended manufacturer battery also. Aftermarket batteries aren't specifically designed for the phone (or device) so there will eventually be some issues.

I just read a lot about battery life and this or that about the battery. Life is all based on per user. Just carry a spare charger and give it a boost whenever its needed. I've blazed through my battery in under 4 hours before. Hell, worst I ever did was 3hrs on my Captivate. Streaming music, downloading full ROMs and working remote desktop wiped it pretty fast, but then again, I expected it to.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] xblack5dahliax:
This rom is amazing I have no problems with it at all I flashed a bunch of the mods that were offered as well. It is much another than stock and I love the blue! Keep up the great work!
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] y2whisper:
Yeah its just weird how we get great battery life for a bit and then it goes away. I simply got spoiled last weekend when I was just using my device like crazy because I was amazed how much battery life I had. its almost as if some tweaks aren't getting run after that first reboot or something.

but again 9 hours is decent, I have a charger and a spare battery so its in no way an emergency.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] eghoti1:
i tried one thing this morning and it seems to help very slightly when on 4G. Underlock the phone with setcpu when the screen is off (there's a screen off profile). I set it to 1.08ghz. the drain seems about 1-2% less per hour on 4G data only so far.

You try the kernel mainline for skyrocket?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] y2whisper:
Downloaded but not installed. reason being that when i had great battery life I was using the ultimate edition.

Sticking with my theory that it was data draining the battery. I am thinking it may have to do with my account sync. as if auto sync is running to hard on something (calendar or contacts) first step is turning it off which off the bat made a difference. now im looking to clear any temp data etc

it seems that when i did a Format / system or some other wipe, it wiped out my APN..

So i just restored a nandroid backup i had from yesterday and the radio started working again.. looked at the APN and it was completely different from what it was when it was not working..
