[Q] Battery Drain Since Moving To Stable?

Hey there,
I was using the CM7 nightlies for a while, and the battery life was great. However, it seems like ever since I flashed CM7 Stable my battery life has went down. The part I'm finding odd is that it didn't even last 12 hours today and I barely used the phone (especially in the first 8 hours since I was at work). As well, the battery usage shows Cell Standby and Phone Idle combined using over 85% power, which I've never seen before. I want to say it might be some of my apps, but they're the same ones I've been using. In case it makes a difference, here's my setup:
LauncherPro
Trillian
Clock/Weather widget from Fancy Widget
SetCPU on "conservative" setting
Gmail, Facebook, Messages widgets from LauncherPro
Power Widget
Score Mobile widget
None of my sync settings are really frequent, most are hourly refresh, another is 30 minutes. And since I haven't had this problem before CM7 stable I'm still thinking maybe it's something with the ROM.
What I'd like to know is if I should try to calibrate the battery first. And if that's the case, what is the best method to calibrate the battery so the ROM is reporting it accurately.
Thanks in advance

Anyone have any ideas?

I have been getting the BEST BATTERY LIFE EVER since moving to the latest radio.

Which radio is that?

Always flash at 100%. Then use your phone at least 4 days, as in 2 complete cycles of using until you have to charge it again. Do not change your radio unless you are absolutely confident about the things you are going to do. Chances are you have a custom rom which does not match the radio you are trying to flash, resulting in a expensive ¨presse papier`.

I appreciate the caution, but the current radio I have is the version that Virtuous recommended to update to. Is there a more "Cyanogen-specific" radio?

I got the stock radio and it's working perfectly. 28hours of uptime with ease (and everything on, incl pushmail). No GPS issues, good reception and no static in the background.

when you say use your phone for 4 days (2 completely cycles) until you have to charge it agian... what do you mean exactly? i need to charge mine after like 8 hours...

What I mean is that you should, after you flashed a new rom, drain the battery at least two times and charge it again fully. Or charge at 100%, flash and wipe battery stats after flashing to speed this up a little. Point is, there is no definite daily use. You could (usually not) notice a very small difference in batterydrain after flashing, but be sure it's not because of Bluetooth, Wifi, GPS or some other thing which is accidently turn on. That's why I said to use the phone for 4 days, and 2 complete cycles. I do not use my phone as heavy as you seem to do. Furthermore, I take care not to turn Wifi, Bluetooth or GPS on when I do not need those functions.

[Q] Battery Draining at 10%/hr

Recently purchased the T-Mobile Samsung Galaxy S2 and I flashed Beastmod v4.2 onto it. I'm experiencing a lot of battery drain, approximately 10% an hour with very minimal usage. I flashed the same ROM onto an identical SGS2 and the batterylife on that one is great. I've tried reflashing Beastmod but still getting the same issues. Anyone knows whats going on or how to resolve this?

How are you flashing it? Wipe everything and fix permissions?
Sent from my SGH-T989

I flashed it following the directions on the Beastmod thread in development.
1. Download it and place it at the root of your SD Card.
2. Boot into recovery.
3. Factory Reset then wipe cache.
4. Flash the ROM then wipe dalvik cache.
5. Reboot!

Beastmod is still 2.3.5, you should consider flashing one of the 2.3.6 ROMs and maybe updating your Radio to the latest , much better battery seems to come with the newer update ...

Why would there be such a large discrepancy in battery life though from one T-Mo SGS2 with Beastmod to the other? That's what is making me scratch my head.

Did u do a battery Calibration? If not this might the reason why

Umm yeah that too ... duh ....
There is a BIG change in 2.3.6 in battery life, at least what I am seeing and others have reported, some say it is the ROM some say it is the radio , I am using both, I get better battery life, but overall the SGS2 Hercules is a battery hog ...

Disable sync for your Exchange email. I found that to be the biggest source of drain.

I feel the same way my man..no matter which ROM I use, my battery drains like a mother

A lot of this can be due to signal strength. If you're in an area where you're constantly disconnecting/reconnecting to the towers, or you're just below the acceptable level for 4g, it might be switching between 3 and 4g, draining your battery.
Another thing to note, you usually want to run a rom for a couple of days before you start judging battery. It takes a while sometimes to build the dalvik-cache, and calibrate the battery. Sometimes as much as 3 full charges.
Lastly, look at what you have running on your phone. If you've tried tons of different roms, and they all drain, chances are it's an app you have that's misbehaving causing wake-lock. I'd try downloading system tuner from the market, and first going into the startup section. Remove ANYTHING that doesn't need to run in the background. You'd be amazed how many apps run at startup that really shouldn't, at least until you start them yourselves. Battery spy and cpu spy can be useful for troubleshooting what's draining your phone as well.

Thanks for the tips. I didn't give it a chance to do 3 full charges yet and I'll take a look into removing startup apps.

From the OP, it sounds like you have more than one SG2 phone available to you. Try swapping batteries to see if the same rapid discharge occurs where transferred.

I did try this but the issue with the draining is still there.

Have you tried changing kernels? Each phone responds differently to kernels and like some more than others. I've tried everyone and Faux's "stock" kernel works the best on my phone. It's UV, on stock speeds with a screen off profile.
To make sure your phone is actually going into deep sleep check the app CPU spy on the market. it'll tell you what clocks your phone is running through and staying at for the most time.
Also, check out System Tuner to see what rogue apps could be running constantly in the background [se Bloatware Freezer to freeze or remove apps as necessary] as well as if your 2nd core is staying offline and not staying on when it's not needed.
I would also throw your phone into airplane mode and compare the drain with no data activation to how you normally keep it to check if the 3G/4G toggling is draining your battery.

[Q] Worse battery life after installing DoomKernal

I'm using FPSE playing FF7 as the test.
Before installing DoomKernal I was getting a drain of about %13 per hour.
After Installing DoomKernal I am getting a 24% battery drain per hour.
I thought DoomKernel was supposed to help battery life. I even cleaned up the running processes. So they don't drain the battery in the background.
I have installing SetCpu but I haven't overclocked, I only used it to set the minimum speed lower.
I have JuiceDefender set to disable connectivity when using FPSE.
Am I doing something wrong?

try fully charging then turn off phone continue charging then boot recovery and press wipe battery stats.
Sent from my R800i using Tapatalk

Not sure which kernal your using with 10 i get nearly as good as stock, so close i leave it, where in the past ive tried them and always gone back to stock
If its V11 i think from memory the GPU is overclocked and in his thread he does state that the effect of this on battery is unkown.
When i say as good as stock i mean at comparable set speeds.

using v11 now, no significant difference than previous one...

I use DoomKernel v10 and battery life is excellent. I use different governers based on what I am doing.
Like smartass and underclocked to 400Megs during night and 1G or 1.2G during and gaming with OnDemand.

Tried DoomKernel v10. Went back to Advanced Stock to emulate the original conditions. No significant difference here between both kernels.

Well I don't know why then. I used the latest one available at the time.
When I tried it, I wasn't overclocking or anything. Left things as is.
I'm now using Cyanogenmod 7 with it's kernel, and I'm getting same/slightly better battery life than stock. But when I was on DoomKernel, battery life just sucked.

I'm really sorry for it, Masters... I guess there are too many variables to understand. Maybe it's a slightly different phone, maybe our modus operandi is different (i proably drain more battery than you, based on your posts).
Anyway, I hope you can find a solution, or maybe in newer versions it will be better. For now, sorry I can't help.

Possibly crippled Radio

Hi guys, I recently flashed CM9 on my trusted KL3 baseband and run into wifi problems which were later solved. In desperation trying to fix the wifi I flashed the latest LM8 stock (slovenia) and subsequently used CM9 with that baseband till I noticed my battery had become like a leaking bucket. During this time it was also obvious my mobile data performance was below usual..... sluggish response when using internet based apps. After a week I decided to revert to stock, expecting everything to go back to normal. First I tried to stick with the LM8 baseband and restore my old nandroid(from kl3).Everything worked fine but the battery still drained and there were constant dropped calls. Then I went back to kl3,sadly my radios still crapping out. Dropped calls, below par 3G response and worst off all battery draining in 5hrs. My device was better than this before, NO dropped calls, 3G
was excellent and I could get upto 20hrs on moderate use... I don't know what I may have done wrong. Each time I wiped everything before flashing with CWM5. Any help guys?

do you also notice worse network signal? i notice that on mine. since i update to baseband xxlm6 and xxlm8 i´m considering flash older baseband. you can do this trough odin (flash older firmware) then trough odin also flash cwm recovery and then aply your nandroid backup. the baseband should stay the old one

My radio fluctuates between 2G and 3G a lot more, even in strong reception areas. I flashed my old baseband which I'm using now (XXKL3 UK) but it's still the same. It seems I've wrecked the radio somehow by all the flashing but it's confusing because I always wiped and formatted everything before flashing.

i think the same thing. i belive that something went wrong with radio. i wish i had a stock W to test my theory

Since my last post I've reflashed stock XXKL3 and begun installing apps afresh without restoring nandroid. Radio performance still sluggish and battery still drains in 14hrs maximum on light use.Was getting over a day before . I guess flashing a custom ROM or a stock ROM from a different region CAN ruin you're phone beyond repair.

Massive battery drain, 122Mhz unused
Since I last posted here, my 3G radio has improved a lot and is close to normal now, but the battery drain is still enormous. After running cpuspy, I noticed the 122Mhz state is unused. The phone does go into deep sleep normally bit I still lose upto 30% while asleep over 6 hours or so. Anyone know why the 122Mhz is unused?

Battery drain on clean Rom installs.

The last few nights, I have tried a few different JB Roms. All with the same results. My GNex has a full charge before I go to bed, I wake to my phone telling me to charge it 8 hours later. With NO wifi or network data on. This can't be normal.
The roms:
ASCENT 3.0
Jelly Belly 4.0
New Unofficial Cyanogen Release.
No extra apps installed. Purely stock.
Tonight, I'll try it in airplane mode, and see if my network coverage is what's draining the battery. But for the most part I'm never without a signal.
Any ideas or ways I can see if the battery is just bad?
Also, what would the current Verizon radios be? I believe mine are up to date, but I guess that could be an issue if it is indeed my network signal being dropped.

Im on the 07/27 fitsugly cm10 rom with r225 franco kernel and for some reason my battery life has gone through the roof, after 30 hours of being on the battery is still at 56%. Granted im not using it much now but still i've never seen this type of battery life before. Overnight the battery dropped maybe 4% at best, wifi is always on and its fetching emails.

How odd have you tried charging up and resetting the battery stats ? May help

I installed the newest version of the ROM. I was curios what the different GPU kernels were for. Is there one that Toro should use rather than the other? I think I installed the 512 version. Should I not have?

Minooch + franco.Kernel #223 (see attached files). I haven't used my phone much in past 24 hours, but battery life is awesome. I use latest bootloader and radio firmware, CPU is set on interactive governor, 1420-384MHz, max screen off CPU frequancy - 729MHz, 512MHz on GPU.

I think I tried that ROM before, not sure if its just for maguro. I have a Verizon toro.

If you don't need the higher clocked gpu speeds then just stick with the 384mhz kernel.

Pretty much identical battery life im getting right now, battery monitor is saying im sipping 8mA of battery when idling.

Yeah, No MiNCO toro release. :|
Went with the ROM and latest Kernel, and I can't believe the battery life. Tonight will be the real test though.

Try better battery stats... I am on gsm nexus.
I tried jelly belly, minco , paranoid android, and xenonHD plus bigxies stock. I've used Francisco Francos kernel on bigxies and that gave good battery life but the others all burned cpu and battery, specifically via Android.mediascanningservice. and maps.
Right now I am back to stock 4.1.1 rooted courtesy of rom toolkit and with better battery stats and cpu spy I have a cool phone.
One thing you should be aware of is if you have a lot of media on your phone the scanning service can take a long time to run and calm down. I I upgraded my bosses razr to ICS and his phone took all night to update I guess he has lots of music on it...
To increase battery life you can install titanium backup and freeze maps, and wallet when I not in use. You can install rescan media from the app store and trunk off media scanning service. Or just buy a bigger battery.
This is not a knock on the custom roms. The rom teams mentioned above they are all awesome and are the reason us crackflashers have so much fun. I have learned lots from this experience and have a better grasp on how my phone works due to the efforts of these devs. For now I am sticking with stock... I'm sure I'll be flashing again soon.

You can never judge a ROM on battery life within a day. Every ROM I flash gets bad battery on the first cycle and most the time even the second cycle. You really have to stick with a ROM/kernel combination for at least a few days to be able to judge battery life. It may just be a placebo effect but I use a battery calibration app each time I flash

Resetting battery stats accomplishes nothing related to battery life or reported percentage. It's been debunked some time back by Google.
