Cell standby consuming more than 40% percent battery?

Is this normal?
I'm using the latest radio and RIL...
32.48.00.32U_5.11.05.14
It's the best I've used so far but I think that this is not normal...

It depends of the other "consumers". 40 % means that it's consuming 40% of the 100% total consumed at every point in time. So, if the overall battery drain is low, 40% from that, doesn't necessarily mean too much.

I see.. it makes sense! Thanks
But wow.. 1 day and 7h and 40% battery? Which ROM/Radio are you using?
I can't even get 24 hours with almost not using the phone..

Id be happy with 24. I barely get 6 lol

I am able to get almost 30 hours of usage and even after that I got 25-30% left. Using 11.14 radio + DeFrost 5.7 with SetCPU on ondemand. Been 15 hours(Mostly on standby with Wi-Fi + Nimbuzz on) and I still got 80% left .

I'm also with this and have results but not as good as you.. maybe because i'm using a Sense ROM I also had SetCPU in interactive.. will try and see if ondemand is better!

Hours will be many if Display on time is low (below 4-5 hours) or similar heavy processing is kept very low. Easy to get near 2 days with that usage with even the stock ROM.

Then I'm doing something wrong... I did calibrate the battery yesterday and it's a bit better... almost no usage and it's now 12hours uptime with 75% battery..
Are there any apps to monitor the apps that use most battery? The stock information is too restricted

They end up using more battery usually. Go to accounts and sync and make sure it isn't syncing crap in the background, by default Sense syncs News and weather every 15 minutes or so which drains a lot of battery. Also I'd recommend using Gmail with push rather than HTC Mail(Unless using the newer Froyo one with Exchange activesync) so that it doesn't check for new e-mails over and over again. Also don't install apps you don't need and widgets also consume battery. Make sure things aren't using Wi-Fi if you don't need them. And flashing richard's OCUV kernel for HTC Sense based ROMs will also help(Along with it use SetCPU with ondemand/conservative governor).

A single screen shot shows us absolutely NOTHING about battery life.
Your battery is also almost full...
Use the phone a full day 100% to 5%, then screenshot your overview, graph, screen on, awake, and signal times. THEN we'll be able to tell.

sorry i missed the first pic my question is i am 82% after 1 hour of screen time with heavy use that means i am getting 5 hour on screen time if that so its very good.

My first day was like this after charging it for the first time when immediately opened it. I found my brightness to be all the way up by default and set it to auto, substantially improving my battery life.

Still means absolutely nothing. Use it 100% to 5% and then report your usage.

I'm using liquidsmooth 1.3, just got this...is this on par or could I be doing better? Didn't browse the web much though, only lurked around xda cos I noticed chrome really sucks the juice

battery life is definitely improved on 4.0.4 , i'm getting between 45min-1hr more screen ON time (mostly surfing and reading xda) than on 4.0.2
i use live wallpaper and autobrightness, wifi always ON, everything stock with no tweaks, stock 1750mAh battery

Can you also post the battery voltage when you almost depleted your battery?
It can let us to see if the battery is correctly calibrated to show the proper percentage value. I encountered up to 1 hour different in screen on time with a non calibrated GN.
To know your voltage, dial *#*#4636#*#* (*#*#info#*#*) (no need press call).
Go to battery info and see the battery voltage value.

The galaxy nexus will always get awful battery. I have never gotten over 2.5h screen time and.I have tried every rom, literally. I can't really get over 14h stanbdy either.

I can verify I seem to have better battery life after the 4.04 update.

Post your battery times

I bought an extended 4800 mAh battery and cover on Ebay and I love it I currently have over 15hrs on the battery and it still has 31% left awesome, considering I am running overclocked at 1809 Mhz.
34% screen
29% cell standby
8% maps
8% internet
8% GPS tuner
5% Android OS
4% Android System
3% Device idle
2% Media server
I keep it in a steel locker at work I think that is the reason for the high cell standby #
My problem is I destroy everything delicate or expensive, and this phone is both. I have been looking for a silicone case but havent had any luck anyone see one?
This phone is going to go shotting out of my hand like a wet watermelon seed any minute now I know it :cyclops:

i get 15hrs on the stock battery?

Standby Battery Usage Glitch

Cell standby attributing to high battery usage is due to a glitch. It reports incorrect usage because of a miscalculation. You can find the fix for that here

What's your screen on time? 15hrs isn't outstanding, especially for a battery twice the OEM size.

Just search ebay for a silicon case. There are literally hundreds. I personally would go with tpu as it is more durable and less flimsy. Also less likely to be a lint magnet.

I can get 20 hours with 3 and a half hours screen on and still have 30 percent left.... Stock battery. Your battery sucks.
Sent from my SPH-L710 using xda premium

I am definitely getting better battery life with the stock battery, with 3-4 hours of screen time. I'm not using power saver feature either. Stock, non-rooted. Wifi on at home, VZ LTE elsewhere.

Heh, i was just interested what other were getting.
My GF has yet to have to charge her SGS3 except for when she puts it on the charger for the night, and has yet to run out of battery.
I've been quite impressed with the battery performance so far.
SGS3 is rooted stock ROM.

Thanks for the link missed that somehow.
Flashed the file and my screen went to 56% and the cell standby droped to 5% ? Is the miscalculation just in how it calculates the percentages? Will have to do some more reading on the subject.
Screen time was 7 hrs 54min
Only 3hrs commando........lite weight.
Lol just yanking your chain

I took these screen caps recently, but this isn't out of the normal for me. Running a version of kyanROM that I modified with kt kernel.

Out of curiosity, does using a 3rd Party battery void your carrier warranty?

Remove it and replace it with the original before you take it to the Verizon store. It all depends on the store and or the clerk, better safe than sorry:fingers-crossed:

Post a Screenshot of your battery drain in the settings and give details about your setup. And what is fast in your opinion? 1% /hour?
Maybe you should buy the extended battery kit?

try flashing different kernels and see which one suits u the best.every phone is different.u may also wanna underclock and undervolt. also change the rom may b if changing kernel doesnot work.ine suggestion.XenonHD rom with its stock kernel.

The stock battery is a joke at 1800 and the extended is 2100...I had both and both sucked although the 2100 was a lil better. I have the 3800 Seiko battery now and that will last me all day. Makes the phone thicker but its better then charging all day and worrying about what's killing your battery.

Turn off features when not being used like data NFC GPS.
Also avoid auto task killers

How much does it drain in one hour? Battery drain depends on many factors. The mains ones would be what kernel and ROM you are running as well as what "features" you have turned on. For example I am running CM10.1 with the stock CM kernel and I usually get around 16-18 hours of battery life with 1.5-2 hours of screen time.. that is with all of the features (gps, NFC, etc.) turned OFF.

How on earth can you drain a 3800mAh battery in one day? Nonstop internet radio AND 3d gaming on full display brightness?

I am currently using PA rom with franco kernel. Normal day = roughly 13-15 hours ish.
By normal day I mean around 30 minutes of talk time, about 1 hour ish web browsing and like what, 30 minutes ish of youtube? Of course, sometimes I am free and end up playing games on it for couple hours lol, but the stock battery seems to be plenty enough to me.

My battery makes it about 15-17 hours,with about 1 hour gaming,1 hour browsing and talk time around 1,5 hours...Xylon + Purity Kernel!

It is what it is. This is Wi-Fi only on this charge:

Turn data off when not using it. You can download a widget for that.
Keep screen brightness down low.
If rooted use setcpu and choose a screen off profile of 350mhz maximum - I find this a real benefit.

Worse battery life with KK

Worst fears realised.
The Kit Kat update has delivered drastically worse battery life.
Could often work with 10% per 45 min - 1 hr screen time before on WIFI, that has now gone out of the window.
1 hr 44 min screen time with 68% left now.
That is quite a bit worse I would say.
Anyone else feel the same?
I would rollback, but the camera improvements are just so much better.

I had about 5 hr screen time and almost 2 days of usage. I am using stamina and greenify though since I don't need emails and notifications pushed, I just manually refresh it.

Nope, I just managed 7.5 hours OST on my last charge on WiFi without Stamina Mode, so quite a bit better for me than JB where 5/6 was more usual. Standby power is also noticeably better, averaging ~0.4%/h.
Sadly the KitKat changes make most battery stat apps useless without root now, or I'd suggest you run one to see what's up on your end.

Cant find anything that stands out. Going to drain and do a charge from fresh.

Did anyone try to calibrate the battery after flashing?
Calibrating battery gives exact battery reading.

There is no real calibration in android and for everybody pls alow 3-4 full charges before reporting your battery life on kitkat(same when flashing new kernel)

same here.
Done full drain but no change. moreover the phone gets heated quickly..

This is obviously a sign of some rogue process running intensively (compare performance after booting in safe mode to confirm). You should be able to figure out pretty easily which it is from the basic battery stats page, sadly no partial wakeleock listings anymore on non-rooted phones though.

How to boot into safe mode?? sorry I am new here and this is my first android ph )
I have done factory reset>>installed 4.4.2 via PC companion>>full factory reset incl internal storage.. heating problem is somewhat solved.
But it gets heated up when connected to charger..which on JB doesn't happened!! strange..
Draining seems to be normal but takes too much time to charge..

I got a great battery life on kitkat.
