Hey guys, recently my arc's batt is very quite fast. So i went and check out the battery use and i found out that cell standby used up about 20-30% of my batt. It happened out of a sudden as previously it only used up a few percent. May i know what is cell radio and how can i prevent it from using up my precious batt? Thanks a lot=)
The Cell Radio is what takes care of all the network communications as far as i know..
How to bring battery usage down i don't know though..

Do you have a bad network coverage in your area, or do you stay in rooms/buildings with low network coverage? If there's no network available, your phone will search for network continiously, draining the battery.
If so, put your phone in aircraft mode if you don't have network connection. I think you can still turn on WiFi after that if necessary.
I checked the battery usage graph. And my phone signal bar is green with occasional white. (hope u know what am i talking about) And when i click on the cell standby icon, it is stated that time withhout a signal is 0% Any idea what is happening?
Hello,
I want to know if my experience is common or not. I had my phone at ~90% and changed it to airplane mode to try and conserve battery while I went snowboarding. Got back to the phone about 7 hours later and it was dead. Plugged it in and turned it on and found out that "NFC Service" took up 80% of my battery for those 5 hours. When I turn NFC off this does not show in the battery log, but I don't want a major potential feature of this phone to be unusable. Anyone else experience NFC destroying their battery?
Thanks.
I am noticing my Galaxy Nexus not lasting as much as my Rezound did, but it had a larger extended battery. I also use Ultimate Juice to enable / disable my internet connection. So with my extended battery + ultimate juice + brightness on 30% or so I still have 29% battery after a full 25 hours. I would just disable NFC because I do not see it in my battery usage. It is only useful for Google Wallet, and wireless charging (correct me if im wrong).
I use the NFC quite frequently during the day by having various profiles set up around my house, and my battery seems to be fine. Are you using a custom rom or kernel? If the NFC battery issues always occur, I would try reflashing your Nexus. Seeing as NFC itself doesn't eat a significant amount of power, I would guess that the Android OS is being kept awake by the process.

Well I got annoyed and was one day from the end of my return window so I went to Verizon and told them I wanted another phone. They gave in and I just got the new one. Hoping the phone was the problem. I was unrooted with 4.0.2 installed. I don't have a huge need for NFC, but I don't like to think a feature of the phone was completely useless to me when I have seen others who leave it on with no ill effects.
Thanks
Just throwing out a question. I see a lot of people mentioning putting their phone in airplane mode overnight and this puzzles me. I can totally understand using airplane mode when you want to use the phone for media/videos/music/games etc. and either don't need phone features or can't use phone features, e.g. on a plane. But while sleeping, the only argument I can see for using airplane mode is for battery savings, but since you won't get any calls or texts, why not just switch off altogether overnight for zero drain rather than a few %? Does a boot up take more battery than 6-10 hours of airplane idle?
Does that make sense?

Yes, it looks like airplane mode at night uses less power than a reboot, at least on some phones.
Moreover, if you happen to be awake at night and want to have a look at something on the phone, it's much faster ;-)
I personally use "setting profiles" from the market and am pretty happy with it (it can make much more than that).

I just plug it in over night. Not really to fuss about battery it lasts me a day so I'm happy

I find that there is not too much of a difference from enabling 'airplane mode' rather then simply disabling mobile data. At least with data off you can still receive calls. If I keep the phone plugged it over night though the battery is extremely hot when I wake up. That being the case, I try to only plug it in if it needs charging.

It depends on reception.
If you have bad reception, the phone will draw more power when radio is enabled.

That's very unhealthy for a Lithium-Ion battery type. With a Li battery type you should try to keep the charge as close to 100% as you can to maintain longevity of the battery. This isn't like a Nickel-based battery, where it'll retain memory if you don't discharge it frequently.
Charging it correctly, a Li battery can be kept very near to its original specifications even *years* after it was made. I have a Macbook Pro that's 2 years old that still has 98% of the total battery life remaining.
Synopsis: Plug in your phone every night if you can. Plug it in during the day if you can. Plug it in while in a car, plug it in while in a bar, plug it in on the planet Mars, plug it in while contracting SARS.
Don't worry about the phone getting warm. It does that because it's sucking in a lot of energy. When it's full, the phone will funnel the energy back out. It's nothing to worry about.
I took my phone off the charger last night and this morning around 9 I looked at my phone and it was down to 50%. I checked to see what could be causing the issues and what was using the most of my battery was device idle and cell standby. With device idle being the most. Im not even sure when this started but i just started checking into it. Is anyone else having battery drain issues? Im stock and not rooted. Ive done a factory set but still didnt work. Ive uninstalled apps disabled all of att apps not sure why this is happeneing. Ive googled the issue and notice that ppl with the s3 are having the same problem weird.

Device idle isnt killing your battery. It is saying while your device was idle this is the energy it consumed. I would say after that much time your cell standy by was your problem(signal or distance ). Idle is not a thing but a state. Was your bluetooth on? Was your wifi on? Etc... 3 items using 11% battery is 33% which could have extended your life 50%
Disable unneeded connections. And switch 4g to 2g (edge) to help. I shut wifi off everytime I leave my house. And never use bluetooth.
Edit: The number 1 killer could be 20% and then you could have 15 things at 5%
They all add up. You should post a picture of batteru stats if you can. (Long touch stylus while holding button)

You should check your cell standby "time with out signal" that is the worst killer.

hi guys,
sorry i'm noob and this is second time im posting on xda forum. I recently bought a Galaxy Nexus Made in korea by samsung. It's currently running on 4.3 latest update phone doesn't lagg or nothing happend like crashes etc but please see below major problems im facing.
Phone getting hotter from back side where camera is installed
0 to 100% it take 5-7 hours to charge ( I tried both wall and USB)
I charged the phone to 100% in night and i didn't use the phone night in morning when i check the phone the batter was at only 12% left. the phone eat all the battery in 7 hours the most battery was used by phone idle 57% and stand by 33% & i didn't put any sim card in the phone whole night and automatic wifi was on which was only 17% battery.
again i charged the phone to 100% close the automatic wifi and insert a sim card
The result is like
After 3 hours 57 mins battery was at 52%
Screen take 49% total screen on time 16m 1s
Phone Idle 22% 3h 41m 29s
cell stand by 10% 3h 54m 55s
Android system 5% (CPU TOTAL 1m 47s *** CPU foreground 33s *** Keep awake 1m 19s)
I don't know what was the battery time before 4.3 update becuz when i buy this set it came with 4.3 and i bought this 3 days ago. Is this a battery problem or the phone problem or its the android ???? any type of help is welcome
Thanks in advance
The Galaxy Nexus is known for its not so great battery. It also just depends on how you use it. If you are playing games, watching videos, etc. it will drain fast. If you just check a few things here and there, it will last longer. That's common sense. But yes, compared to other phones, the Galaxy Nexus sucks with battery. Theres not much you can really do software wise. The best thing you can do is get a bigger battery or a spare battery. I have a charger pretty much wherever I am so battery isnt an issue for me. But if you are someone who is on the move all day, I would suggest a spare or an extended battery.
EDIT: Actually, looking at your screen time, you are getting a bit above average on phone idle. Right now, my phone idle is at 8%

Yes i read that and i planned to get extended battery but the cell eating the battery while screen is off. I'm just confused about the OS 4.3 i read alot about that after updating to 4.3 nexus 7 user experiencing of slow charging and battery draining but as you seen in attached pic the phone eating battery without any usage the total on screen time is 6 min and in 3hrs 57 min 48% battery gone ?? so in your opinion what is the prob is it OS, phone or the battery ?

Well I see in your screenshots that it looks like you don't have any cell service. What could be happening is that your phone is constantly searching for a connection, which could eat up a lot of battery.
best bet

youre best bet if rooted and unlocked is to install a custon kernel and underclock it to about 1000 mhz ... install dark themed apps or theme chooser theme also us a black wallpaper .. turn off 4g . ... turn off nfc when not in use .. make sure youre using the oem charger to charge the battery .. use wifi whenever possible .. also turn off anything like hotword detection that is constantly listening

The mobile service was on but data service was disable i received 2 calls and some texts msgs 2 but they are not long or didn't took the battery. All syncs were off and location to. But the battery is going down very badly. Please see new attached files of last night. The cell was at 87% battery and in the morning the battery was dead.
Try using something like Better Battery Stats or GSAM and see what they say is draining your battery.
With the current info given, I would lean toward thinking it is a hardware issue. Perhaps your battery doesn't properly hold a charge anymore.

Few hours ago i left for office the cell was on 14% charging and turn-off the cell and put it in pocket. After 1 hour when i reach to office i was trying to turn on the cell but the battery was dead and then i put it on charging and it start from 6% and turned on. I think the battery is not holding charging . The battery is in made in Korea and have NFC details on it. I think its the original battery but its not use able any more. i will try above mentioned widgets before changing the battery.
new screen shots
didn't use the phone and it ate all battery. Any guesses what's wrong with the phone???
need a fast reply.
Try updating the radios (I don't remember how to do it. U dial #something). Also, have gps and 4g turned off. Auto brightness turned on. If u have the Facebook app, get rid of it and just use the mobile site.

4g/3g are off and i ticked use only 2G network. Facebook app is deleted brightness is set to auto GPS every thing is off but mobile consuming battery without any usage.... im just confuse about that its the hardware prob or i have to flash some other rom?
bump! any 1 with solution ?
U really need to get better battery stats. It will tell u specifically what wake locks r causing the problem. Idk if using only 2g is a good idea, u may be burning battery with apps constantly searching for a data connection. Can u access wifi? That takes up less battery than data (3g or 4g). U may want to buy a new battery, they aren't that expensive. U can get one on amazon for like $15. If that doesn't work, I'd try flashing a different rom, maybe even a custom kernel.
I am still running 4.1.2 because I like it better than the newer versions and my battery life isn't bad. I usually get close to 2.5hrs of screen on time. More than a day of standby. Obviously, if I make a lot of calls I will get less battery life. I'm running eclipse rom with leankernel.

Today i flashed Cyanogen mode 10.1.3. i didnt flashed any google apps just to check what eat battery. When i flashed the ROM the battery was at 36%. I used the mobile for almost 1 hour and on screen time was 54min 37sec and battery left 16%. The cell eat total 20% battery in 1 hour continues on without mobile data network and 2G was on. Wifi GPS every thing was off and brightness was set to auto. At 16% battery i stop using mobile and after 30 mins i check mobile it eat 6% battery in 30 min without any usage. then i truns off the phone and after 30 mins i tried to turn on the cell the battery was dead. then i plugged in the charger and i turn the cell on. The battery charge start from 10% but instead of charging i start loosing battery. then i charged for almost 1 hour on 0% battery and took 5 hours to fully charged. My cell phone drain all battery over night under the usage of phone idle 73%. I'm just confuse about that its the battery issue or its cell phone problem. and my phone getting very hot from back left side. I just need a good developer advise if this is hardware issue then i'm gonna replace the cell phone and if its the battery issue and hardware is ok then i will get a new battery and continue using and 1 more thing my phone get little hot even its turned off from back left side and sim jacket side.
Bump! any suggestion ?
I doubt a developer can answer that question. Could be phone, could be battery. I would try a, new battery just cuz it's cheaper than a new phone. Maybe go back to stock and see if that helps. If not, call Verizon and complain, they may send u a refurbished unit.

I flashed ICS 4.0.4 but the highest stat on battery graph is phone idle. The battery was 36% in night and after 3hr 1min the cell was dead. then i put the cell on charge and checked the stats. Phone idle was on top 43% , then screen 30%, cell standby 19%, android system 7%, media server 2%, Android os 2%.
