High batt usage for cell standby?

Dear All,
I've playing around with my fren's SGS2 and looking at the battery usage.. Seems like Display is taking 36-40% of his battery on the SGS2.. And cell standby on his phone is only using 6% of the battery..
On my OB, the display is only using 6% of the battery power and cell standby using 45%..
I was wondering whether is the cell standby taking up a big amount of the battery and causing my phone to run out of battery so often.. Althought the nova display is saving alot of power..

Just remember,it's on % not an exact point

can we flash the baseband?

Same problem here. I think it is a bug. There is no way that cell standby is consuming this much battery.

what baseband ? sgs ?

Well it depends. If you leave your phone overnight its cell standby will be at a higher percentage than display, since the display wouldn't be used at all

i think using 10% of battery to standby for 8 hours seems too much.. BTW.. I am using singtel networks..

i did not test on those custom rom because some of the things i need may be taken away..

Hi
I am using Zeus v1 rom and I have the same problem. At night with phone in standby, in about 8h it spends 10% or more. With everything of and in 2g and gsm.

I have the same problem when using the indian based official GB. My battery drained in 10 hrs of minimal use. no wifi or 3g just 2g service. I followed the instruction on flashing another GB update which is for V20b & v20n but did not succeed in wiping data & flashing superuser. I am still waiting for helpful guides from the seniors here.

With regards to the original posters comment you need to remember that the percentages that are posted when you go to the battery use in settings are a percentage of the battery used. The only way that the two handsets could really be compared is if they have both been used in the same way for the same amount of time.
How long are you getting out of a charge and how heavily do you use your phone will give a better indication of the standby usage in relations to your friends handset.

rocket rom v10 battery usage

Hi all Im using rocket rom v10 but battery uses 1% per minute. I have read posts on the rom thread but cant post there yet. Using Betterbattery I have Surfaceflinger using lots..... after 10minutes screen now 85% battery 83%.

Yeah I have the same issues, many of us do, dunno from where that is, kernel or rom or android 4.0.4 or the lrk base??? , deep sleep is perfectly fine, but once screen is on, it's ridiculously high..

Alternatively you could take the overclocked NoteCore kernel and underclock it.
The kernel is undervolted, so disabling higher processor frequencies will give you the benefits of undervolting and the benefits of underclocking.
I.e. low power consumption and low temperature.

Its not a 4.0.4 LRK issue. I was running a rooted stock build and installed NoteCore kernel without any issues. When I flashed Rocket V10 it was only then that the battery life became crippling. Shame, I love Rocket and the tweaks but guess I'll go back to stock!

Could u help how much underclock and undervolt....
Sent from my GT-N7000 using xda premium

Take a look at the NoteCore thread in the development section for the undervolt details.
The overclocked kernel is undervolted.
Install the overclocked kernel then use something like Tegrak to limit the processor frequency to 1400 or 1200 then you will get the reduced battery drain of using lower voltages and lower frequencies on your processor.
Don't change the undervolting set in the overclocked kernel add this had been optimised.
Sent from my GT-N7000 using xda premium

I don't think it's the kernel's fault for the battery drain.. I think it's the modem..
I have been using notecore with all the touchwiz roms no battery problems at all

RR 10 with NoteCore 13
Just installed NoteCore 13 8hr ago, and plug the power cable for charging. Still plugged now, but the SpyCPU report shows that during the past 8hr, the phone didn't go into deep sleep (while I was ) , but it stays at 100Hz.
Will unplug now and go to work for a day. See if I can get a usage report after work.
Cheers

Yep, definitely faced the same problem, which was the reason I switched to Classic Rom V4 (because of the newest firmware) but actually, though battery life is better, it is still worse than with AlBA v4...I haven't been able to determine whats behind it...

After a normal day usage... The battery drain is still heavy... When screen on, the percentage dropped around 1% per a min or two.
Dunno why... Deep sleep state is ok.

2nd of RR10 with NoteCore 13. The screen-on drainage improved. I read my whole travel time (around 1.5hr) on newspaper via 3G signal, and the battery went from 100% to 81-82%, which is acceptable for me.
Again, Deep sleep works perfectly.

I left this good rom because of this, deep sleep ok, but when the screen is on, too heavy battery drain. same with 2 kernels, should be another reason.

I tried with notecore and speedmod. I have used RR10 about 3 days to have several battery cycles. but I felt a big battery drain when using the note, even at low brightness, with nothing strange in CPUspy or BetterBatteryStats.
so I switched to JB liquid. Yesterday night. I would not say it is better for the moment to be honest. New rom, new kernel, not even a beta, so hard to compare, but you are right I feel the same today: high drain with screen on.
(but whatever the battery drain, with palm rejection available on CM9/10, I will switch again to a sammy rom)

I really cant seem to find a way to lower the screen on battery drain , its ,horrible ,
been on latest std notecore and speedmod , and with both i cant seem to get more than 2:00 - 2:30 hours of screen on time & basic use (in total of 10 - 12 hours ) , deep sleep is perfectly fine with 1% loss per hour (sometimes even less !!) , but with the screen on , battery just goes bursting -1% per minute........
we do need our devices to be used , not rested on deepsleep the whole time , otherwise this defies the whole concept of a "smartphone"....
on GB it was very good ,it got worse when Samsung introduced ICS (but was manageable) , but now on 4.0.4 , its just horrible and unacceptable!!! dunno what kind of testing Samsung does before rolling out an update...
sorry for the whole rant and rage post in there , had to speak it out cos im struggling here..
would be highly appreciated if someone can help or a suggest a 4.0.4 rom with a "reasonable" screen on drain... im even considering going back to RRv7 (4.0.3) cos as far as i remember i was getting good battery out of it (deep sleeping and screen on was great there)
cheers.

My batery drain is too much in this rom any sugest

How's your battery life on the incredible s ?

I'm not sure that if my phone has a low battery life or others as well . When I go to bed , my phone was at 70% and I wake up after 8 hours of sleep . My phone dropped to 58% . Is that a normal case or should I get a new battery pack ?

i'm using 1800 mugen power battery. it's better on about 20/30 % and you can really see that. so if you want to buy new battery - better buy this one than original. i'm working with it for half of a year n everything is fine.
about your battery - yes, it can go in that way and its normal for our dev.

Mine is about the same as yours, 100% at sleep and 88(at times it's 87 or 86) or so when I wake up. But I think I slept for about 10h
Edit*
Atm it's at 80% and it has been on battery for 13h exactly

im having issue with poor battery life on this device too up to 5hrs ~)

A tip is to disable sweep2wake if you have it enabled. it consumes a lot battery. Since I disabled it yesterday my battery gained a couple of hours battery life.

Using Longevity on CyanVivo X Rom and very impressed with the battery backup, Lasting over 18 Hours with average 3G data use and gaming before it was like 8-10 hours with Juice defender. Don't keep data on all the time otherwise use longevity Worth a try!

Imo it's just placebo effect. I actually think that they waste battery than save.

About battery saving apps:
Some might help save some of your battery, like Juice Defender, but about 100% of the stuff that an app does is something you can do for yourself.
Like dim the screen when you don't need 100% brightness, turn off data and use only GSM when you don't need to use data (and if 3G has better reception it might be worth staying on 3G though, at least in my world a better reception would mean a little bit better battery than if you changed to the network mode with worse reception) and when you don't need WiFi - you turn it off.
Using apps to kill other services and apps are not a good idea either, since some apps will only restart and restart and restart while the task killer will keep killing = both apps will drain your battery.
And by turning off both WiFi and data and the apps are well designed, they should not try to look for updates and such if there are no available internet connections.
And, by undervolting you gain more than using different apps and such and if you then learn how to set up your device in the best way for battery you will get longer battery life.
If I don't use my phone so often, I can get about 2 days with 3G/GSM + WiFi turned on all the time and mobile data connection turned on all the time. If I use it a lot I still get long enough battery time to make a full day, usually I need to charge my phone every 18-24 hours when I use it to check mail, send some texts and read news (and XDA, as the addicted person I am).
Now, I just hope that I haven't f*cked anything up - I'm just too lazy to read it through.

I bought myself a Nexus 7 about a month ago to satisfy the cravings for that Jellybean goodness. After trying several ICS/JB roms on my IncS over the past year, I decided to revert back to the CM7 Nightlies. Much to my surprise it's almost as if I forgot how blazingly fast Gingerbread was.
Given how i use my IncS on a daily basis, I seem to be averaging around 34-36 hours before it hits below 5%. It really only gets used for calls, texts and wifi tethering to my N7.

I used to average 30% battery drain per day with light use with stock GB rom and kernal, it has upped to approx 50% per day with stock ICS rom, with lOst profit's overclock kernal running at 1400 wake and 368 sleep. ( setcpu )
Not bad considering 40% increase in processor speed, but less than 20% increase in battery usage.
Addy

I tried latest cm7 nightlies and it wasn't smooth at all so I reverted back to jellybean cyan x
don't know why you are saying that GB was blazingly fast...
My battery is so bad on the jellybean ROM though!!

keep in mind you have to give it a couple of hours , maybe even a day(depending on how much it has to do and your connection etc) Before the rom settles down after flashing. Then you can give your impression of it if it is laggy or not.

[Q] Battery life

Hello everyone,
I wonder how much battery life you have on i9000 with stock battery (1500mHa) on cm 10.1 with semaphore kernel?
Asking, just because I can only get max. 12h of battery life with cm 10.1 20130218 rom and semaphore 2.9.10, smartassv2 and row. Wondering is this normal or my battery needs to be changed. Any suggestions to max battery life on i9000 would be appreciated too
Sent from my GT-I9000 using xda app-developers app

The battery can last between 3hours and a week, depending on how you use your phone, so that's not a good question to ask.
If you feel that the battery is running out too quickly then download betterbatterystats and look for any apps using unusually high partial wakelocks or alarms and get rid of them. It only takes 1 rogue app to screw up your battery life.
Sent from my GT-I9000 using Tapatalk 2

I think he knows that.
12 hours uptime is not uncommon, especially when on 3g a lot. On wifi you should be able to get at least 20 h in my experience. If the battery is as old as your phone I suppose its capacity is not what it used to be, and you might consider replacing it with a sgs+ one f.i. - they come cheap nowaways!

That's in your experience, the way you use your phone.
Try playing NFS MW or something. You'll get about 2 hours on a gti9000. It varies far too much to try and tell people how many hours battery life they should be getting. Totally depends.
Sent from my Nexus 7 using Tapatalk HD

I use my phone for 3h wifi browsing, 30 min. music and 30 min gaming, but nothing intense. And with this usage I get 12h battery life. Flashed 2.3.5 stock rom. Still getting 18h max. So I think this comes to conclusion that my battery is old enough. That's why I asked for the battery life you get, because I didnt knew this is usual or not

My last for 2 days more or less depending on usage.

AW: [Q] Battery life
Guys i think its wrong to measure the battery life with how long your phone is working. i personally look at the screen on time it says more than just how long our device is working. I get always stats around 3h its unimportant if my Phone works 6h or 18h.

had only 2g on.
but when i was at home with wifi on, was some more than 3h
but the phone was already 1.5 years old when i go it. must now be 2.5years old. never changed battery (maybe because of that i had bad battery..)
now passed to the lg optimus l9 get every day 4h screen on time, great standby time.
ow btw i'm sending text messages hole day with go sms. (browsing the web is more battery friendly..)

Flashed PA ver. 8. and the battery life improved greatly.
Now i get about 3.15 hours with screen on an improvement of 50% over the cm10 unofficial of pengus.

Lol.that is placebo or user app related,you are using same kernel on both roms and only maybe few little batt. tweaks in tony's rom which don't make that much difference
Probably you had app battery drain couse there should be verry slight difference between this rom's in terms of battery usage
I have tested both,and the drain for me is the same...
