What is "time without singal" in "Cell Standby" - Captivate General

Hello,
Half of battery used on my cell phone is "Cell standby" and in Use details it lists "Time On: 1h 55m 3s, Time without signal:50%".
I'm excellent reception area (5 bars) and definetely did not have my cell off the network for half of the time. Does it include unavailable GPS location or some other type of "signal". This drains my battery very quick and I have not a slightest idea what does it specifically means. I have GPS, bluetooth ON but WiFi is always OFF.

This shows up on my phone when I leave it in the car in an underground parking garage. I haven't noticed whether it drains the battery more than when it has signal sitting idle, though.

It's time and battery your phone spends searching for signal and it's looking for cell signal not GPS.

So "time without signal" of 50% means that while phone was up half of the time it did not get cell reception? This is completely impossible in my situation.

I think it's a glitch. I notice it from time to time. You'll probably notice that when it happens it shows "time on" as twice the amount of time your phone was actually away from the plug.

wifi or 3G for battery consumption

what is better to use... when it comes to battery consumption...
wifi or 3g?
and is there a big difference in speed?
sorry for the newb-like question...
Wi-fi is better for battery life, and its usually faster than 3G
Sent from my SAMSUNG-SGH-I897 using XDA App
I found, according to Juiceplotter, that my phone dies a tad bit quicker when I'm connected to wifi at home as opposed to 3g. Funky but true. Slopes of wifi usage decrease a lot quicker than the slopes for 3g usage.

I was losing 30% every night with my phone sitting with the screen off and wifi set to never sleep. Last night I disabled the wifi and lost 3% over 8 hours even though I was only getting 1 bar or signal and have autosync on for weather, facebook, email. I am going to try to leave wifi on tonight with it set to only stay on when plugged in and see how much it will drop.

I agree setting wifi to never sleep will kill your battery quicker than 3G overnight. I use Wifi when I am at work because it is faster, I am not 100% sold on the idea that it uses less battery than normal data. Especially if you do not normally use a lot of data.

[Q] Question about battery life related to radio...

My school is in the boondocks (not really) and has virtually no cell service in half the rooms. Is there a setting I can tweak to make the phone stop constantly searching for a signal if it loses signal so that it doesn't drain the battery so much when I'm here?
For a comparison, last night after being unplugged for 4 hours, I'd had the display on for 15 minutes and I was at 94% battery. Right now I've been unplugged for about as long and I've had the display (on a lower brightness) for about as long, but my battery is at 84%. Nothing appears to have taken the battery other than Cell Standby, the rest of the numbers are miniscule, between 2 and 3%.

THere is an app for that. I just looked at the market and found this:

[Q] Battery Usage Spikes? (mA)

It would seem that looking at my Battery Moniter I would get random spikes that send the (mA) into the 900's. Then slowly begin to drop after watching it for about 10 minutes where it starts off at 2(mA) for about an hour and a half. I'm not sure if its the 4g kicking in or not but Juice Defender should be stopping the 4g while the phone is off.
If I could get some input on what would cause such a spike then I would have an above average battery to last throughout the day.

I am kinda curious about this too. I don't personally have this problem but i read on one of the forums(outside of xda) that it was either a radio tower switch (back and forth between 2G and 3G/4G) or a loop in the actual programing.
Until the battery drivers are fixed none of the numbers reported will be very accurate.
Next time you think it is spiking to 900 or a high number try using a task killer and kill the battery monitor widget and then restart it...anytime I do that it then displays back down to 2mA.
...so to make a long story short dont trust anything it is telling you. The only accurate guage is physically how long the phone runs before it turns off.

Battery life question

I recently bought a g2x. I previously had a Optimus v with cm7 that I liked, so I pretty much immediately installed cm7 on my g2x. I've noticed my battery will drain 25% on stand by overnight. Just wondering if this is normal, and if the stock rom is any better in this regard?
Well...its normal but at the same time its not, and i'll tell you why. Mine drains about 5-10% overnight (around 7 hours) and with wifi on it is usually even less, about 3-5%.
Though there HAVE been instances where it has drained about 20-30%, usually I just pull the battery (or restart the phone a couple of times) and it seems to fix it till the next time it happens.
In fact just last night it drained 35% =\ but normally it is around 10%.
Im on weapon G2x
My phone drains about 3% overnight. Wifi and data off. CM7 with Faux kernel and setcpu screen off profile.

It honestly depends what kind of network signal you're getting.
I've had mine drain a considerable amount one night just because I had low signal. Especially when you have low signal AND data on.
Mine drops 5-10% at night, sometimes less. I either keep it on 2G with data off or wifi with wifi calling on. Wifi calling seems to save a ton of battery.
But, leaving data on and 3G on I drop 30% or so.
yeah, as everyone says, depends on your usage (and/or signal). i've gotten 12h, i've also had 4 days, it really differs on lots of factors.

24% overnight battery drain, Note 10 Exynos

Hi, i have Note 10 Exynos Version, phone was fully charged (100%) at time i was gone to the bed around , i turn off all the futures like wifi, NFC, Etc... i shocked when woke up and found battery is on 74%, i had s7 edge and never face sych iss5its hardly uses 3% max un standby, sometimes My note 10 drain 18%, 20%, i had checked everything but couldn't found reason for battery drained in standby, not installed any fancy app, its not show any background uses of any app, i dont know how to attached screen shot to this thread otherwise it will clarify more about issue..... help me to resolve ..
Sync and Bixby routines are major candidates for overnight/standby battery drain.
Even i face the same overnight drain issue which never happened with my S10+, but not as much as 24%.
It has also got to do with your network signal strength in the place were you live.
Hi , the point you mentioned about network signal strength seems possible culprits, i barely get 1 to 2 bar signal strenth (idea network) at home, secondly sync and Bixby routine was already turned off, is it possible that poor signal strenth should tole that much on battery? I had s7 edge and its it's never drained that much battery even at poor network signal strength

Look under your battery settings, should show more detail about what is consuming what amount of power and go from there.
Hi, if i turn-on the flight mode at night before bed, phone won't drain battery at standby, its draining graph stayed flat at night, so i assumed that main culprit is poor network signal.... by the way can u enlighten me how to add/attached screen shot herewith if i wish to? As i dont found any option menu for that....

To attach an image, scroll down a little and there's a button to attach it or you can upload it to imgur.com and share the link here.
As for your battery drain, the main culprit is always bad battery signal. So maybe try locking it to 3g and try it out.
Sometimes when the network is bad and the phone wants to sync, it will fail and keep trying. It's an issue which plagues samsung to be honest. Had it once as well on my note10.
