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%
[Samsung Galaxy Nexus] Ranker:
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 ?
[Samsung Galaxy Nexus] jsgraphicart:
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.
[Samsung Galaxy Nexus] cupfulloflol:
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.
[Samsung Galaxy Nexus] Ranker:
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.

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.
[Samsung Galaxy Nexus] Ranker:
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 ?
[Samsung Galaxy Nexus] cnoevl21:
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 ?
[Samsung Galaxy Nexus] cnoevl21:
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%.
[Samsung Galaxy Nexus] mrgnex:
Try going to 4.3 via fastboot. With the flash-all.bat that will wipe everything. That might solve it
[Samsung Galaxy Nexus] Ranker:
ok i will try it currently i flashed the 4.1.2 and flashing a custom kernel for battery saving i will post result soon. and I'm also having slow charging issue like my cell charged to full in 5-6 hours.

I think i have find the solution. I live in Asia Pakistan. I think the baseband version I'm using is not for my country. If some one can suggest me the baseband for Asia may be this can help me.
[Samsung Galaxy Nexus] cnoevl21:
When you are flashing new roms, are you wiping data, cache, etc? Do you have bad cell signal where are? Maybe your phone is constantly trying to find signal, that could cause battery drain
[Samsung Galaxy Nexus] Ranker:
yes when i flash Rom i wipe data/cache and i get full signal but the most battery is used by phone idle. I purchased a new battery today i will charge it to full and check it in night if it drains the battery like same then its may be hardware or the radio because most of battery used by phone idle.

I'm still going to say it has something to do with the lack of cell/data connection. Or at least a GOOD connection. "Phone Radio: 64%" isnt normal at all. You say you turned it off but I dont know if you did. Otherwise, Phone Radio wouldn't be so high. Remind me again, do you have a cell plan? If not, it could constantly be looking for cell service. Not necessarily just a data connection, which are two different things.
[Samsung Galaxy Nexus] Ranker:
No I don't use Internet through mobile service provider. In my country only 2G available and Internet is very slow on 2G networks. I use wifi for Internet & i just Installed 2 apps SetCPU and Battery App. I'm testing a new thing and i will post result after 10 hours. I'm just confused between the cell and the software. If it's due to some software or radio which causing high battery drain then may be a solution available but if its cell phone issue then i need to replace it. and my phone get little hot from back side left/right side of camera when its in standby mode. Is it normal or Its some kind of hardware problem ?
[Samsung Galaxy Nexus] jsgraphicart:
Try this, maybe when you go to sleep, turn on airplane mode and leave it for the rest of the night. Or maybe just turn it on when you dont need your phone. Then see how your battery does on airplane mode. If its better then it has been, then I'm still going to say it has something to do with your data/cell service.

My galaxy nexus has always had bad battery life even with extended battery, its just the phone man

His drain is not normal GNex battery drain.
[Samsung Galaxy Nexus] cnoevl21:
+1 on trying airplane mode. But I think it has to be ur phone trying to find better signal. Where did u get the phone from? I remember when I moved across the country I had some crazy battery drain because my phone was still using the east coast satellite or cell tower (not sure which) while I was on the west coast. I had to update settings to what satellite my phone should connect to. It used to be able to be done by dialing #611 but that doesn't seem to be the case anymore.
[Samsung Galaxy Nexus] Ranker:
I tried this on Air Plane mode still the phone Idle was at 67% and all battery drain over night in 7 hours plus time. Yesterday i turned off all the things in phone like auto brightness etc, charged to 100%. In setcpu Governor Powersaver. Then i dialed *#*#4636#*#* and i did following thing.

1. turn off IMS

2. turn off Lte ram dump

3. smc refresh update

4. toggle DNS check 0.0.0.0(not Allowed)

by doing this i got 14hours 5min battery time and 35% was remaining. But still when i checked phone in the morning the phone idle was on top and after 2-3 min usage screen came on TOP. I think its not the Hardware issue and i flashed Jelly bean 4.1.1 via odin and then i flashed the other radio from fast boot. Below quoted radio i flashed.

But still the phone idle taking alot of battery. I will test a new thing tonight again and will post the result after 20 hours. I will buy a data plan for 1 day from carrier and i will check how much battery it consume while data network is on.

Phone is made in korea but i think it came from some Europe side.
[Samsung Galaxy Nexus] lightson:
I'm sorry if these have been suggested. But, have you tried flashing the stock factory image. Let it run stock for few days without installing anything. Don't forget to turn off all unnecessary features (GPS, NFC, etc).

What about your cell signal quality? Poor cell signal quality could make phone work harder to find good signal.

And, make sure that the battery is still good. :)

Btw, this is my battery usage for your reference :)

Your battery timing is pretty good. I turned off all things like GPS, Wi-Fi, Mobile Data Network, i ticked on 2G network only, NFC off all type of syncing is off and in my area i don't have signal dropping issue i always get full signals flashing other radio seems little better the current radio was xx which is for Europe recently i flashed some japnese Radios which are for other Galaxy nexus models the result seems better. I will test these settings for at least 1 week so rom get stable and if the result is same then may be i have to find out some solution 1 thing is confirmed its not the battery and cell hardware.
[Samsung Galaxy Nexus] jsgraphicart:
All I can say is that in every screenshot you are posting, it is showing no signal bars in your statusbar indicator. And your phone network, or whatever it was called, is showing high percentage. This is telling me that your phone is either constantly looking for service and/or a data connection. This will happen even if your phone is idle, which is why you see your phone idle at a high percentage as well. This is why I suggested airplane mode to see if you would still get battery drain with all the radios turned off. If you say it didnt help much then, I'm sorry, I have no other ideas as to what could cause it. From your screenshots and the description you give of your data use and availability. Thats the only logical explanation I can see. There is no reason your phone network should be that high.
[Samsung Galaxy Nexus] lightson:
agreed. based from his last post with lots of screenshots, I see that actually the phone said that it connected to an unknown network (the grey network icon showed that it can't connect to a data service). and the first screenshot showed that (no network or unknown signal).

I also suggest flashing back to stock and try airplane mode :)

please correct me on this :D

btw, OP, can you show the detail of cell standby usage? :)
[Samsung Galaxy Nexus] Ranker:
here are the new screens. The signal bars you are watching in status bar are grey because no data network connected. but i'm getting calls and texts on my cell. When i connect the cell to wi-fi those bars turns into blue color. Today i will charge the cell to 100% and i will test Airplane mode and i will post result after 20hrs.
[Samsung Galaxy Nexus] jsgraphicart:
That was my point. If your signal bars are all grey, but you havent turned off your cellular radio, its constantly looking for a better connection. You having a weak or no connection like that is causing your battery drain.
[Samsung Galaxy Nexus] Ranker:
here are the new screens while airplane mode was on. any idea why what's wrong and which thing is draining battery ?
[Samsung Galaxy Nexus] cnoevl21:
I see 100% for no or unknown signal. I may be getting texts and able to make calls but for whatever reason ur phone is constantly searching for service. That is most likely causing the battery drain. I don't know your country at all, but do you have other cell phone providers available? Maybe another service would give u less battery drain. I still think, since u say ur phone was previously used in Europe that your phone is still using the European satellites and since you're not in Europe this is obviously not good because you want to be using the closest satellite and towers possible.
[Samsung Galaxy Nexus] Ranker:
I live in Pakistan its near to India, Afganistan, China. But I dnt understand 1 thing that the cellphone was on air plane mode then why it keep looking for network ?? the radio was off whole night but it still looking for the network ???
[Samsung Galaxy Nexus] cnoevl21:
True. It shouldn't happen in airplane mode. Maybe it is a hardware issue. Can you return it? I doubt this would help, but may go back to factory unrooted and try updating to 4.3. I don't think this will change anything, but if u can't return it or get another phone, it wouldn't hurt to try

I'm testing a new custom rom. It's giving me 17% battery perhour on continues use but on stand by its really sucks Phone idle always high and phone dying without useage under 17-23 hours. I have noticed 1 thing that phone consume more battery when its in stanby mode.
[Samsung Galaxy Nexus] cnoevl21:
17-23 hours isn't bad. I get 20-30hrs depending on usage. I basically get 2.5-3hrs of screen on time. But I also have 3 batteries and a separate charger so I never have to plug my phone in. I always have a charged battery on standby. Maybe u should just do that and stop worrying abt fixing the problem.
[Samsung Galaxy Nexus] Ranker:
yeah I also have a seprate battery now but dont have a charger and my slow charging issue solved with fast charge. My office is start again and now i can check how much back-up my nexus give me before nexus i got Xperia P that phone give 36 hours backup time with 4-5 hrs screen on time. If my nexus give me 12 hrs with 3-4 hrs screen time that's enough for me.

Today is my 3rd day with last flashed custom rom the battery drain is now 4%per hour without any usage. I'm using following settings

ROM : Vanir 4.2.2

Full Black Theme

PREF NETWORK 2G ONLY

DATA CONNECTION OFF

SYNCS OFF

APPLICATION INSTALLED ONLY 1 (BETTER BATTERY STATS)

CPU UNDERCLOCKED

CPU : Min 350 Max 1060

Governor : Interactive

I/O : FIOPS

CPU Under Volt :

350 mhz : 775mv

700 mhz : 883mv

810 mhz : 934mv

920 mhz : 985mv

1060 mhz : 1013mv

So is that all i can get from my nexus or it can be more Improved ?? I'm happy with my Gnex for this but if it give me a little more on battery then this is the best phone. Is there any other tweaks i can do get more juicy battery .
[Samsung Galaxy Nexus] cnoevl21:
What's the point of having a smartphone if u have the data turned off all the time? R u using wifi at least?

I have wifi and data always on. Data only kicks on when there's no wifi.

There was a thread on here I used months ago abt saving battery that had a lot of little tweaks that were in the developer section (u may have to unlock that, ask someone who has ur rom how). The thread may have been over on rootzwiki which is why I'm not seeing it so do a search for power or battery saving over there.

[Samsung Galaxy Nexus] nshaziq89:
my mom s4 once had similar problem.

i go to settings>developer options>and ticked show cpu usage.

and compared it to my nexus(function normally).

i noticed that the "android.process.media" is constantly running compared to my nexus. and it turned out, it was a bad SD card causing the phone to keep scanning it and causes heating and battery drained.

why dont you try looking at the cpu usage and compare it to other android that function normally to see whats the prob.

hopes this helps.

I'm just waiting to get the phone stable first then i will turned on the Data network. currently I'm figuring out that what's the real problem of battery drain. When I created this post the phone was giving me 4-6 hours on battery doesn't matter i use or put it on standby & the charge time from 0 to 100% was around 7 hours. But step by step checking things doing different tweaks today the same phone charge in less then 2hrs and giving me 24hrs standby time and upto 6hrs on continues use but still thats not enough and thats not what google promised as TI OMAP chip have alot better saving features comparing to Exynos in s2. But still i just want to learn some more things about this beast how to control it.. basicly I'm a heavy user of application and i like to try new roms etc etc etc but until my Gnex get fully stable I will keep looking for a stable battery tweaks. Currently when i fully charged my phone to 100% at start the battery drain is 2% per hour and it keep increasing and in the end of battery it reaches around 5.5% drain per hour on standby. but some one told me that the normal battery drain is arround 1% per hour and i have to find some more solution to achieve that.

If you turn 2g on your phone will not connect to mobile data. Looking at your first post the signal is grayed out or you have no signal at all. Which is why the battery drain. One of the previous posts stated turn airplane mode on. And use WiFi. I would do that. The nexus is a CDMA/LTE correct me if I'm wrong but using 2g will not work and it will keep searching for that connection. Achieving 1% bat drain on a gnex impossible in my opinion unless you absolutely don't use it. But every phone is different so good luck.

I recently noticed that my standby battery drain is a lot worse than when I just got my Z1. Checked battery stats and saw that the android os process is keeping my phone awake for hours. Also, I think my stamina mode has stopped working, because before, and just like my tablet z, when u unlock the screen, i usually notice data is off for a sec, then it comes on. I don't notice that anymore. Any ideas why. Thanks.

Reboot your phone as far the Android OS battery drain goes and for me it stops usually... As for the stamina mode, if you allow apps to still work in the background in stanima mode,it will still show wifi icon...
