[Q] Crazy high cell standby killing my battery life?

Help!
I'm running the 81xx firmware on a direct-from-dell unlocked Streak.
My battery life has so far been abysmal, and looking at the battery usage screen, my cell standby is usually over 60% while idle is less than 20%, everything else like 2%. This isn't from weak signal, though; I am in a well-covered 3g-only area and my phone has reported only being disconnected about 4% of the time.
Another strange thing is, my data indicator is constantly switching between the H symbol and the 3g symbol.
Anybody know what's going on?

It might be that while you are well covered for 3g, you are marginal for HSDPA and that constant switching back and forth is using your battery. I have not tried it but have a look and see if you can disable HSDPA in settings somewhere and see if that helps.

i'm usually around 40% cell standby.. do u have any task killer apps installed? although people think those are useful they usually do more harm then good.

I have the same problem, and I used another Android phone in the same location (hence same cell coverage) with no such problems. I just took my phone off the charger and had the display on since then non-stop. Cell standby used as much battery as the display!! There's no way that is appropriate.
I'm running build 8102, but it was the same with 6941 before. Can't tell about 1.6 as I bought my streak used with 6941 on it.
What Android version are you guys running? Maybe we can find common denominators.. :/
Edit: here's a screen shot of the battery usage after a while off the charger with the screen on constantly:

Do you think your antenna might be loose or defective?

I can't imagine the antenna to be loose really - but who knows, I bought mine used. If so, I think there is a signal strength value in " about phone" somewhere, no?
What signal strength are others getting? I'll post mine later, I'm on airplane mode right now so that I get some battery life.. :/

For signal strength, I am getting -75 to -95, and 9 to 12 for the two values while riding the train (not subway).
It also appears my battery life is quite good when my phone is in standby and not doing anything... the problem seems to come from net browsing or anything else that uses an active connection... Just browsng XDA is taking about 2% a minute!
Oh and my android is the 81xx 2.1 version with the modaco tweaks

I had really high cell stand-by too. then i installed juicedefender, now my cell standby is down to about 29%.
I think the main thing is that it disables data connections while your screen is off and only turns it back on when the screen is on and unlocked. It also has a setting where it enables data connection periodically to allow background syncs and whatnot.
I'd recommend you guys give it a go, it had almost doubled my battery life!!

Mine shows,
cell stand by 50%
phone idle 44%
it seems quite common on the streak as I read in all the forums. I am on 2.1 stock rom? what's 1.6 like?

Battery constantly drop 10+% every night irregardless whichever rom installed

my battery is dropping like mad recently, no matter which rom I use, JVK JPG JPK, all the roms that is known for good battery life, with various kind of modems.2G network taskilled everything before sleep, no gallery bug, no background data updates, not connected to wifi BT GPS, battery stat wiped, more than 3 times full cycle charge..I have done everything I could, the battery still drop like mad.I fully charge the device at 12am, took off the charger, the battery is 88% when its 8am..checked the batter use, cell standby 40+%, display 20+, phone idle 20+..no more and when I slide the menu, for nothing, just slide for fun, scroll the app drawer, see the apps flying, it drops another 1%..lol
I had no idea what is happening, maybe the battery is dead? but I checked the batter health it says good..should I buy a new battery or what
p.s.I had only 1-2% drop everynight back in a month time, but now... ... ... Is this some kind of hardware failure or battery's dead?

12% for 8 hrs is NOT that bad. I get around 1.6% drop per hr with Wi-Fi ON and push notifications.
Anyways, See if you have a Time without Signal entry under Cell standby. Keeping a phone in a low/no service area can drain the battery faster.

You should recalibrate the battery after each rom flash. I think there is an App somewhere in the forum which is really easy to use.

Did you check for Time without Signal ? Maybe cellular reception in your area has deteriorated.

time without signal 0

Or maybe just general poor reception in your bedroom? When I'm in school (a nice plain concrete building to prevent young software developers from ever finding joy in life) I have 1-2 bars of edge reception and my phone loses with data off around 1.5%/h.
Either that or your battery has lost capacity and you can fix the issue by buying a new one. My bet is on the reception.

nah not possible..I placed the device on the same spot everyday..back in a month time it constantly dropped 1-2% but now 10+%..its not about the signal or reception or what I guess..it may be due to the frequent flashings recently..anyway I just ordered a new battery..see if it works =(

I second that. In my basement lab at university, ~1 bar EDGE reception, 1.5%/h is not untypical

Is it searching for WiFi connections that is what used to drain mine when sleeping .

Hold down your power button. Set data network mode to disabled.
I was getting 10-15% battery drain over 8 hrs of stand by with data network mode enabled.
Now with data network mode disabled (when I need it I just switch it on again) I get 1-2% drain for the same time period.

Turn off all networks, including 2G (put your phone in to airplane mode) and leave it overnight. If the battery still drains the same then you can make sure it has nothing to do with 2G/3G/WiFi/BT or GPS.

well if its not about 2G/3G/WiFi/BT or GPS then what could possibly be the problem?

running apps or worn out battery

What is the point in buying a smartphone, if needs turning off everything?
I suppose your custom ROM is a wipe install
10% battery drain overnight seems to be fine. If you use background data and auto sync, keep on Wifi because that will do the job quickly.
Widgets are notorious battery drains, esp weather widgets. Remove all type of widgets from display. Change sync interval for facebook/twitter to 3, 6, 12 hrs etc... from 15min, 30 min.
Check sync interval for apps like Pulse, buzzbox, weather apps

Just a thought.. how about letting your phone completely discharge. When restarted, immediately flash to stock rom, allow that to completely discharge, repeat process several times (3 ideally) then load your custom rom of choice.
If it sounds absurd, I agree. It really does! However just remember, electromagnetic charge carries resonance memory, much like xrays. This old school trick is not often related to modern batteries, but have found it to increase battery life with several Android devices.
The main things are screen brightness and running apps. Your problem sound's quite normal even. Considered a secondary battery?

I think it is fine because if I use wifi (i.e. browsing XDA forum), it use ~8% for HALF an hour.
Anyway why don't just shut it down when you are asleep?

your battery dropped because you on wifi, at least, the thing is, I din even connect to BT wifi GPS, no task running in the background(taskilled before sleep) and it still drops 10+%..jus imagine if I had my wifi on overnight

What is "Cell Standby"

Sorry for the noob question, but what exactly is "Cell Standby"?
So far today, i've used 50% of my battery, of which 37% was consumed by my display which is fine, but 17% was consumed by Cell Standby!
When i go into check, it says i have been without signal for 100% of the time, which cant be right as i have an "H" and 3 bars of signal at my desk for most of the day, and besides i've been using the internet so it knows i have signal.
I've also switched off WiFi and Bluetooth.
I did an autoupdate of the firmware yesterday, i wonder if thats causing it

Doh should have used the search better.

looks like i have to manually go to settings and about and status to get this to correct itself.
seems stupid?

Yes thats a work around on the bug, I dont know why thats never been fixed.

any idea if its just a visible thing, or does it actually affect battery life?

Idle Battery Drain

I've been getting a lot of idle battery drain after only a couple of weeks and it's very disappointing to see. I used GSAM Battery Monitor (after granting the additional permissions via adb) and it looks like my three biggest issues are Phone Services, the OS itself, and Google Play Services. I have attached screenshots below of the information from GSAM.
Anyone experiencing something similar or know of any way to fix this?

looks like it is your app usage not your screen that is using most of your battery. Try closing/uninstalling some apps.

If you look at the first post, the "apps" causing the majority of battery drain is the Kernel and Call Services. That's my problem, but I don't know how to fix this.

My battery is good. Can you go to settings, battery & power saving and take a screenshot of the bottom of the Battery usage screen. It shows what apps are using what, just like the app that you are using but stock android for statistics. Phone idle is using the most for me with 4% followed by Screen with 2%. I have had the phone on battery for 5 hours and 15 minutes from a full charge and still have 90% battery left. I usually end the day with about 60% or 70% battery life remaining.
Also are you using wifi calling? Do you need it? Turning it off might help your battery.
EDIT: also even if call services takes up 16% and you don't have any apps running then you are only using 16% of your battery. I you have 32 apps open using 1% each you are using 32%. From the screenshots it looks like you are using a lot of apps which means a lot of battery drain.

"My battery is good." Doesn't really help me man, mine was good for the first couple weeks I had the phone, but my usage habits haven't changed.
Phone Idle is at 32%, Call Services is at 12%, Screen at 10%, Snapchat at 8%. I use WiFi calling as there is almost no signal at my apartment. When I leave however I turn it off.

Ok, Yeah I was just using my battery as a comparison. Looks like phone idle is eating up a lot of battery and It is probably because you have low signal or because of the wifi calling. Not sure which as I don't use wifi calling. You might want to look at getting a Sprint Magic Box. https://www.sprint.com/en/shop/serv...16=magic box |All&question_box=magic box |All
Only problem is that it isn't out yet so you would have to preorder it. The good news is that it looks like it is going to be free.

Did you figure out any solution to this? I'm having similar performance on my Sprint G6 and not sure how to fix it... All these people reporting 5-6 hours of SOT have me really jealous.

I use greenify and hibernation manager.... It says it might slow down the performance of the phone but I can't tell the difference.

Norc?

What do you mean, "it helps with the idle battery?" What exactly are you referring to that helps?

I'm having the exact same issue with my sprint g6. Battery was fine until recently. Nothing has changed, no new apps or anything. Adb reports call services draining the most, just like your screenshots. Anyone ever figure out the culprit for this issue?

I haven't figured it out yet, but I really hope someone does. I read somewhere that resetting the phone fixes the issue even in the long term but I don't really want to back up all my data and apps and everything to try it.

Try using iRoot, maybe it can rewrite how your phone uses different apps to save battery.

Anyone have any luck solving this? I'm having the exact same problem with the same phone - Sprint LG G6 and "Call Services" is my primary battery drain.
I don't have particularly low signal - med/high for most of the day and I have wifi calling turned off. I've had this same problem across multiple phones (G5 and G6) as well as across factory resets on both phones. I used to get great battery life with my G5(~85% at the end of the day if I didn't use it much) and then this started happening about a year ago.
Wakelock detector is showing >1000 wakeup triggers from call services - the most by tenfold above everything else.
Seems like it might be related to Sprint/LG since Call Services has mostly LG related processes running on it, but unfortunately that doesn't help me get rid of the battery drain. Any ideas?

LG V20 Battery drains on "Phone Idle" and Wifi is always on.

Hi guys,
Hope you all doing great.
Guys i have LG V20 n using from last year. It was working great without any issue. Battery timing was awesome. Giving me 5:30 to 6 hours screen on time. Almost day and Half on normal use. 2 days back something happened no idea what. Now phone idle using more then screen on time and wifi is always on even its off. I tired to uninstall app, then factory reset but still same.... No luck.... Any solution ??

Go to your location setting use the tab in upper right, click setting and turn wifi scanning off.

I tried this but no luck
As i mentioned i tried everything thing, like location off, wifi and Bluetooth scanning off, play services off, Almost everything is off, but still same. No luck...

Try to install battery monitor application (I use betterbatterystats) to find out what is causing your idle drain. But to be honest, I've never got 5-6 SOT. My idle drain is about 0,7% per hour with greenify, managed Google play services wakeup, custom kernel, kernel adiutor and about 80 apps on board.

I'll try and help the best I can..
Within the last year or so..I have been reading about this issue quite often. That is, people posting about "Phone Idle" having high percentage in battery stats. And then they are off to hunt down the culprit. The truth is, "Phone Idle" is NOT eating up your battery. Phone Idle is just that.... Time the phone has spent being idle (being still, or CPU/Battery not being used). Or in this case, percentage of total battery "usage" that belongs to "Phone Idle". In actuality, phone idle isn't "using" anything. The "usage" for phone idle is really time NOT used. A higher percentage is better. If your phone sat for 2 days straight without being used...the phone idle % will be real high. Also, you can't "Greenify" phone idle. You only greenify phone idle when you greenify other apps.....think about it.
And as for Wifi. The Wifi radio on this phone is a bit more power hungry. It doesn't even include any power saving options that some phones, like my Samsung S4 has. My S4 used on average from 2% - 6% depending on signal strength. The V20 can use from 7% - 11% ..again depending on signal strength. If you leave Wifi on overnight and it's in bad proximity to the router..10-11% is normal.
What is your average signal strength for your 4G and cellular (calls)? CDMA has 1X, I'm not sure what GSM uses. If it's in the high 90's and higher, that right there could be chewing up your battery. Phone radio often doesn't even show on the usage list.
How often do you need to charge? Also how much time between a charge and what is your usual screen on time now..after you wrote this post? Phone idle is only at the top because the "idle" time now exceeds the amount of time you have your screen on. ......don't take this the wrong way but some people think the phone idle is actually something that's draining the battery. It's not..it's just placed within the list. Ignore the Mah it shows for it. That just assumes it's some app and it tries to convert everything into mah..and I really don't know how accurate that is. But it obviously doesn't apply to Phone Idle. Speaking of...what is the amount of phone idle time?
