Cell standby drains my battery (~40-80%). Anyone the same problem?
Same here, do not know if could be a software or hardware issue.
Not evry h7 suffer this draining from "Cell standby", so when I write to the assistance they said to bring them the device for "further investigation about the device problem".
Suggestions?

After not using airplane mode for 2 Days I'm on 33%
But in the night I need the airplane mode. Not really happy with the battery life but it gets better. I also call the service in saturday they wanted to report it to te technical service and said its normal. I think its because of 5.0
High % of battery used by cell standby means you are not using device much, it is normal. Also note that battery stats are not always accurate. To increase standby time make sure to close all background apps and turn off mobile data before letting phone idle. It'd be much easier to tell if there is a problem if you post screenshot showing battery stats and screen on time.
Mention any battery related thing in "All battery discussion here" created for all battery related things , Thanks

Hi,
I watched my battery info a moment ago and don't know if those stats are normal.
Cell standby: 42%
- Time on 19h 44m
- Time without a signal 100%
Display: 20%
Android System: 15%
Phone idle: 7%
Android OS: 6%
"Cell standby" seems to use much battery power and my phone signal strengh does not show more than 2 of 5 "bars" in the notification bar (inside buildings). Data network is not enabled.
Now I'm not sure if the antenna of my phone might be defect cause of this high battery usage. I am also sometimes not reachable if people try to call me.

But you miss the key component battery used in that time span .
1% battery used 90% used ???
Your post reads as phone not receiving a signal .Phone sleeping/not in use .
Of the battery used in that time 42% was cell standby NOT 42% of the battery 42 % of the amount used .
more than 2 of 5 "bars" in the notification bar (inside buildings)
No network will guarantee any reception inside buildings . Faraday cage and all that .
Test the phone outside the building first for signal strength .

If you know you wont have signal turn airplane mode on, to save it from searching for a signal all the time, and thus draining some battery.
@Jesmicael: Thanks! I'll watch this thread.
@JJEgan:
My phone uses about 12% battery within 9 hours. No display, no data network, no wlan, no gps, but about 1h of listening to music in this timespan.
I got signal inside buildings most time (with 0-2 bars) but it also happend to me that I was not reachable, even when I placed the phone next to an open window. Outside of the building I have maximum signal.
I did not have any problems with my older LG phone in the same situation.
Of course I know that this 42% are just compared to other battery users
@veyka:My phone is not placed in an isolated cage, and I want to be reachable in this time. Airplane mode is good for saving battery, but not when you want to use a "phone" ^^

Phone gives full signal so nothing wrong with the phones hardware or antenna .
Your alternative is to take the phone to a service centre .

Seeing as you're pretty much putting your phone in stasis for the 9 hours of usage. i think its pretty normal drain. it just looks like the only thing the phone is actually using is the antenna.
Just a wild idea, did you set the phone to GSM/WCDMA auto?

Yes, but does it matter, if I have no data connection enabled? If so, what should I use instead?
Maybe this battery "drain" of the cell standby is normal, when I do not use the phone in this time. On the other hand I am a bit confused, cause due Samsungs official data sheet, the phone should last up to 620h in standby with 3g enabled.
Of course the realistic value is less than 620h, but not 6 times less.
Ive come to realise that this might just be an erroneous stat. I honestly don't think it takes up 100% of my battery. Cell standby has actually deceased since I've flashed villainrom 2.1
any one else have a clue?
I had a theory that since my gsii its actually gt-i9100t not gt-i9100 it might make a little,difference.. whoo knows.. :/

I've come to the conclution that the SG2 is not for use it all day, I have turned it on this morning connected all day to wifi/dataplan and after 14 hours the battery is dead. Will not be able to use it for an entire day.
Pd: wanted to share a pic but seems that the forums are not allowing the png format.

mine lasts all day even with pretty heavy useage mate
you will get about 5 hours screen time on average from this device and battery .
I suggest checking to see if you have killed samsung bloatware that likes to run all the time , installed juice defender which helps a lot , adjusted your start up programs , installed latest firmware or a custom rom like leomar2.1 , if you cant get 3g signal switch to 2g only , switch wifi/gps/bluetooth off when not in use .
Doing all of the above will get you excellent battery life and you will easily last through the day .
The only way i can kill my battery in a day is with some severe gaming sessions and dlna sessions or internet browsing sessions
Battery and phone are fine its the setup thats important
Hope you get it sorted peeps and have a great day too
Look its really normal. You phone will use power in standby, so there is really nothing wrong. The numbers are relative.
Hie guys, I just woke today to see my phone was off and when I switched it on the battery was @17%, from the battery stats in settings it shows my phone switched off after 2hours of me sleeping. So what can really make a phone lose 74% battery whilst it's OFF??!!
Help me or you can paste me a link to where similar problems have been discussed.
Thanx.

Download a battery calibration tool off the market and use it, I have had this happen to me before where i would lose over 50% of battery life just by restarting my phone, and it would gradually go back up.
Also check if their are any updates for your rom and os you are running

Probably a pointless exercise since it's been proven you can't "calibrate" the battery in an S2.
I've had something similar happen, I was raping my battery with a torch app then restarted. Before the restart I had about 90%, after it was around 30%.
Could it be a sign of the battery failing? I've not had any real problems otherwise..
Perhaps you have wake locks? Purchase better battery stats or download it using the search button.
A high battery drain is often a limiting factor for a great user experience.
With BetterBatteryStats you can analyse the behavior of your phone, find applications causing the phone to drain battery while it is supposed to be asleep and measure the effect of corrective actions:
- Spot drainers based on detailed information about the root cause
- Use the online Knowledge-Base to find how to reduce or remove the wakelocks
- measure the effect of actions to reduce drain
- detect changes in the awake/sleep profile and quickly find the causes (rogue apps)
I think we've ALL been here. Is there any uniform answer to this?
Let's be honest, I'm one of the not so frequent xda user, I always read several articles but have been, so far clueless.
I have the international model running on CM10 and constantly switch between ROMs of stock and CM, I've always liked AOSP ROMs, love the simple and uncluttered interface as opposed to the ever so bloated touchwiz. What else can I say? It has 32GB SD card and 16GB onboard storage, and it has a little trouble with 3rd party chargers (lose connection / disconnects every so often ) Its an old phone in technology time, but its still great.
So, I've tested wirh CM, stock and 2 other kernels which still make me feel like the phone is gobbling up a power plant everyday. One main culprit is Cell Standby which is very odd since it's usually just in my room (I use an other phone otg) and has a pretty decent signal (3-4bars)
On the most recent checks:
Cell Standby - 25%
Android OS- 18%
Screen - 15%
Google Services - 10%
Phone idle - 10%
Android System - 6%
And the rest are some of my apps..
I just recently started using Deep Sleep Battery Saver and wakelock detector. I'll send the info when the results are in for a day.
I'm not that fond of using 3G since data rates in my country are time-based and the KB-based pricing is off the charts. So I only use my phone for call and text and the occasional casual gaming and browsing (usually the cnet app)
I can only say that, if we could help on this either way, there are a ton of xda threads related to fast battery drain with varying issues because of Androids openness, I can only think if there would be some sort of centralized thread for this, or if you guys could help. That would be pretty awesome.
Ask any question or request anything so I could get this phone going. Thanks
Cell standby will be highest because you don't use your phone.
It's not a culprit,it is normal that it is up on the chart
But if you are experiencing any battery drain of more than 1-1.5% on standby then you have to look for an app or similar service running in background otherwise there is no problem
Press thanx if i helped you in anyway...
I don't think so. I left my phone's battery last night at 29% and after waking up 6-7 hours later, I got 16% left.
So that's around 13% consumed in one night without using it, or 2-3% drain per hour.
I already greenified Facebook and Lookout which were the biggest wakelocks, deep sleep gave me no noticeable difference even on Slumberer mode. I'm suspecting this is due to cell standby. the location which my phone was in had 3/4 bars of signal, wifi and location services are also turned off.
What's the big problem here really? I suspected it may be due to facebook but nothing has changed so far
Update: Signal strength is 73-80+ dBm, When I got home today the phone was dead from 16% this morning. The highest consumer is Cell Standby at 26%, Facebook is already turned off and everything, Still no perf difference.
So I also have a friend on and he's got a GS4, battery life was terrible for him since the kitkat update.
Anyone??

Hello all, I hope I'm posting in the right section.
I've been searching for info on the battery drain problem for some time now. I have used GSam and System Panel to find the culprit and observe it for a while and I think I see what is happening. Don't know if there is anything to be done but I'm hoping there is a fix out there.
Background:
Stock Verizon Samsung Galaxy S4, stock Rom on latest OTA update (screen shot attached)
One morning around Christmas time my phone drained the battery from full to 10% in about 5 hours. I had my phone in my pocket like every other day at work, I had noticed it was heating up as well. I got an error message at some point that morning about some kind of "Samsung Power Share" I had never heard of. Then I could not get the phone to charge unless powered off, and that very slowly; it was the "grey battery" problem. This problem persisted for several days and then turned intermittent then nearly back to normal, though never quite right.
What I've done:
Wipe cache, FDR, replaced USB charge port, replaced stock battery with Anker battery.
The new charge port dramatically improved recharge time and eliminated the grey battery error but I still have terrible battery life compared to earlier in this phone's life, in other words, compared to before the latest OTA which appears to be a disaster. Didn't notice any significant improvement with the new battery.
Here's what I've seen:
As soon as the battery drops below 50% the rate of discharge maxes out and this matches up almost exactly with the activity or CPU usage of the system process "krtccd." (See attached pics showing krtccd activity corresponding with increased battery drain below 50%). GSam shows the "Kernel Android OS" (in which is krtccd) using 50% of the battery where it used to be that the screen was the biggest drain, pic attached.
Is there any way to control "krtccd" as it seems to go rogue? Why does it only seem to go rogue when the battery gets below 50%?
This is a company owned phone so rooting is not an option unfortunately.
Thank you so much for any input you may have!
I apologize if this posted in the wrong part of the forum. I did do a lot of attaching for info on what the krtccd process does and why it changed so drastically with the last OTA update but I can't find much out there or in here. I don't have the option to root phone so am I such with this weird poor performance whenever the battery drops below 50%?
Thanks again, I appreciate any input you guys have.
As a follow-up, here is a screen shot from System Panel this morning showing that "krtccd" stopped activity as soon as the battery began to charge. I don't get it, it's like it spins full bore in the background sabotaging the battery for the last 50%.
BTW, the discharge last night (in my first set of screen shots) happened while the phone dat idle on my windowsill, don't think I even turned the screen on during that whole time as I was in discussion with a friend. It's weird...
Rooted Galaxy S4 (Sprint)
Same issue. Can anyone provide any information on what this process does?
Someone opened an issue report with android open source.
Issue 160689: KRTCCD Bug?
Since updating to Pie my M5 standby is much worse. It used to be brilliant.
Exact same problem with my device Used to last weeks on a charge, now I'm lucky to get afew days out it while on standby. Looking at the battery consumption details it's due to the wifi not being switched off when locked (despite the settings saying to switch it off.)
I posted on the UK huawei forums and there's no response. https://uk.community.huawei.com/other-products-52/mediapad-m5-pro-10-8-and-wifi-sleep-4822
I have to manually switch my WiFi off when I've finished using it. ?
Mine drains in airplane mode. It used to have amazing standby battery life.
A typical 'update' then. Worse RAM management and worse battery life.
