How the heck do you guys get that much battery life? The most I get is 9 hours on the extended battery. Android os, for some reason, is always at 30% battery drain
[Samsung Galaxy Nexus] EyeOfTruth:
+1 to franco's kernel.

http://xdaforums.com/showthread.php?t=1422956

I use my phone for business and 50% of my usage has been do to voice calls but almost 5 hours and only 25% drain. So if I Didnt have those calls I would have only about 12% drain I have heard people having rumors of even better battery life. I am tempted to see if running at 700mhz/1200ghz might give better batter life. I am currently running 700/920mhz. I also leave bluetooth on and never connect to the internet with wifi (I have unlimited data so using 4g is way faster then wifi)

I use my phone all day, then stream media at the gym for 1 to 2 hours on the extended battery. IF you dont have CPUspy get that add see where your phone is staying at.
[Samsung Galaxy Nexus] Firon:
Have you tried wiping and starting fresh?

You could also use CPU spy to see if your phone isn't entering deep sleep. It's probably an app you have installed. I think betterbatterystats will tell you what app it is.

My battery life's been quite solid, though I'm using interactiveX as my governor (and running imoseyon's 1.6.6 exp4 kernel),
[Samsung Galaxy Nexus] piperat:
about 2 hours. I never shut the gps or 4g of either.
[Samsung Galaxy Nexus] shadowwolfy:
what's the proper way to wipe battery stats? Charge to 100% then wipe through CWR?
[Samsung Galaxy Nexus] piperat:
The gnex wipes automatically for you, and it auto calibrates. What he is saying is that you have an app that is draining your battery. Go into your settings then go to battery. It should show you what is draining your battery. If you cant find it there download the app he mentioned to find the culprit. When you find it, uninstall it.
[Samsung Galaxy Nexus] bnguyen1983:
350mhz 40% of the time, 50% in deep sleep. Drain is still pretty bad
[Samsung Galaxy Nexus] topxshelfxtre:
I have had a bunch of freezing with reboot issues serveral in a row i am using Gapps any idea what i can do to make it more stable or does my phone just not like the custom kernel???
[Samsung Galaxy Nexus] Tsoflyyup:
My drain only seems bad when im using the phone...like i can watch it count down but when the phone is sleep batt is great....i may try 13 franco kernel...
[Samsung Galaxy Nexus] bnguyen1983:
I'm counting down my battery right now. It dropped 25% in the last hour. What's another kernel that someone could recommend?
[Samsung Galaxy Nexus] Mr. Steve:
If you are trying to get better battery life and don't mind being a tester of sorts, Imoseyon's new kernel, 1.6.6 experimental 4 has been probably the best for battery life so far that I have seen.
[Samsung Galaxy Nexus] Juvenall:
...doing what, though? Not to be condescending, but there's a huge difference between watching a movie or playing a game and replying to texts. There are also a lot of apps that just burn though battery life. For example, an "HD" Wallpaper app I was playing with a few nights ago was draining the battery ~1% every minute or two. After 15 minutes of use, it accounted for something like 45% of my battery life since I took it off the charger 8 hours earlier.
[Samsung Galaxy Nexus] piperat:
Either they have an app/widget draining juice or a bad download. I've been on all kernels and the battery life is great on all of them. I seem to get about a hour more on imosey kernel then Franco's, but that's beside the point. My point is that i don't think the kernel is the issue. You have either a bad download of the kernel/rom or an app/widget draining juice. You should download any of the previous mentioned apps to find a culprit and if you can't find one then assume a bad download. Redownload rom/gapps, factory reset your phone and start over. Then pay attention to what you download in segments and watch your battery life. The weather channel widget use to kill my battery life and when i got rid of it my battery life quadrupled. I have a extended battery(verizon one) and i get about 20 hours with moderate use. Ie 10 mins of phone calls, 3 hours average online, couple of hours of games, and about 50-75 texts a day. Then after that i got around 10% left. My job requires long drives and long days thru out the week, so yes this is a normal for my phone to go thru before any tries to flame. I have it set on hot plug with 125 uv on all parameters. Hope this helps.
[Samsung Galaxy Nexus] bnguyen1983:
I was replying to texts and this thread. No live wallpapers, no widgets nothing.
[Samsung Galaxy Nexus] Firon:
The screen uses a TON of power. Like, crazy amounts. The cell radio uses a fair bit too, so if you're constantly texting, of course you'll use a lot of power in an hour.

What do you have your screen brightness set to?
[Samsung Galaxy Nexus] bnguyen1983:
Yea but it should not be 25% in an hour. I was on stock and AHD and i get 12+ hours a day. I just flashed another kernel and so far its been better but we'll see tomorrow.
[Samsung Galaxy Nexus] jam10238:
4 hours of constant screen on is about the best you will get out of the gnex....no matter what rom and kernel
[Samsung Galaxy Nexus] fubaya:
I lose 2-3% per hour when the phone is in my pocket in deep sleep, but 25% per hour with the screen on doesn't sound bad. It's just so hard to judge. I've spent two hours playing with the phone off and on (about 25% off and 75% on) and lost 40% and felt ripped off powerwise. Then I've spent an hour doing the same thing and lost like 10% and been thrilled.
[Samsung Galaxy Nexus] extensive:
I can't connect to my home wifi but could with stock. Any ideas?
[Samsung Galaxy Nexus] rlaxton:
DL link is timing out, is there a mirror anywhere?
[Samsung Galaxy Nexus] bnguyen1983:
IMO its bad because ive never seen that happen before. Ive never been able to actually count the % going down on stock. That's why I think its something else that's going on.

Imma put it through use tomorrow after a full charge and Ill see if there's any improvement.
[Samsung Galaxy Nexus] gnexdude:
You can also turn your screen all black (revert) if you do a lot of reading like I do on the browser...its easier on the eyes too!
[Samsung Galaxy Nexus] toastedoats:
Links not working for me either
[Samsung Galaxy Nexus] wljohnson05:
Anyone having issues with the phone not turning on occasionally? Yesterday I was at work and pulled it out of my pocket and it would not come on...I had to pull the battery on it and turn it back on.

Then this morning my alarm didn't go off because of the same issue.

Anyone else having this problem??
[Samsung Galaxy Nexus] jestercing:
Yea I've had the same issue
[Samsung Galaxy Nexus] mcampbell:
It doesn't happen often to me anymore, but yeah, it does happen.

I've found it more often when I manually turn the screen off; I've been relying on just letting it shut down on its own lately and that seems to have helped.

Also, I've started rebooting the phone when I wake up in the morning. I hate the "superstitiousness" of that, but it seems to have made the phone a lot more stable.
[Samsung Galaxy Nexus] Juvenall:
If you're undervolting your device, and/or you're using the interactiveX or hotplug governers, try turning them off to see if that helps.
[Samsung Galaxy Nexus] Firon:
Here you go, mirror on my server. http://firon.net/xda/GummyNex0.5.6.zip
[Samsung Galaxy Nexus] :
One thing I've noticed when switching from stock to Gummy 0.5.6 is that apps will occasionally re-arrange themselves within folders.

I have a folder on my homescreen dedicated to Google Apps, and every so often the order in which they appear changes. Certainly not a deal-breaker, but a bit disorienting. Has anyone else experienced this problem?
[Samsung Galaxy Nexus] wljohnson05:
I haven't messed with that. It's whatever the default stuff is when flashing gummy. So unless it undervolts it by default, it shouldn't be any of that. The default governor is the interactive. I went ahead and changed it to ondemand.

Any other ideas? I can't have it locking up overnight and making me late to work.
[Samsung Galaxy Nexus] Juvenall:
Have a look at the post for the kernel GummyNex is using. It doesn't sound like they would apply to you, but he has a few suggestions and that thread may be more capable of helping you narrow down the issue (since my understanding is this is more of a kernel issue than one with the rom itself).

[Samsung Galaxy Nexus] hslayer:
Hey guys,

I am currently running Android Revolution HD rom, but I would like to try this rom on my phone. In order for me to install this rom, is there anything that I have to prepare before I install this? (i.e. uninstall previous rom? etc?) Thank you,
[Samsung Galaxy Nexus] kejar31:
update released :) .. read the change log in the op... No need to wipe data as long as you are coming from 3.0 or higher of Gummy... Also you must as always install gapps when installing an update
[Samsung Galaxy Nexus] :
Nice downloading now
[Samsung Galaxy Nexus] hslayer:
but i am coming from different rom, not the previous gummy.
[Samsung Galaxy Nexus] Jdella681:
Just installed, wiped davlik and batt stats.. not pulling any 3g/4g.. any suggestions?

edit: turned on wifi and off, 4g up and running
[Samsung Galaxy Nexus] gnexdude:
I came from ARHD too.. all you got to do is follow the instructions in the OP. Flash as u would any other rom and then flash the gapps before rebooting. Good luck.

[Samsung Galaxy Nexus] extensive:
Had 2 questions in here and I just get ignored. Anybody else have issues with connecting to wifi? I can't connect to my home wifi WPA2. Really appreciate if anybody chimes in.
[Samsung Galaxy Nexus] evilkal:
That's only 1 question. No I can connect to wifi just fine.
[Samsung Galaxy Nexus] EyeOfTruth:
I also connect to wpa2 just fine. My connection also hides the SSID. Maybe try installing a different kernel I run francos just fine or try downloaded the kernel only that this rom uses.
[Samsung Galaxy Nexus] Juvenall:
A question like that would really only get the attention of someone else having the same problem. So it's generally safe to assume that you're not being ignored, you're being indirectly answered with a "no". :-)
[Samsung Galaxy Nexus] extensive:
Thanks for counting. I figured out my other issue. Tried to figure this one out but best I can tell its now having issues with my router(s) or just WPA2 in general
[Samsung Galaxy Nexus] rlaxton:
It works fine for me
[Samsung Galaxy Nexus] hslayer:
so i dont have to uninstall or delete my ARHD rom? I can just install gummy over ARHD rom?
[Samsung Galaxy Nexus] tonm156:
Are browser bookmarks syncing for anyone?
[Samsung Galaxy Nexus] extensive:
D/l gummy

Boot CWM

Data whipe

Install zip-gummy

Install zip-gapps

Clear dalvik cache

Reboot
[Samsung Galaxy Nexus] i_am_the_one:
They sync for me
[Samsung Galaxy Nexus] gnexdude:
Yup that's it...
[Samsung Galaxy Nexus] gnexdude:
Remember follow the open instructions...you got to wipe data I think because you're coming from another rom
[Samsung Galaxy Nexus] hslayer:
thank you very much for this instruction. one question, what is dalvik cache and where do i go to clear it?
[Samsung Galaxy Nexus] extensive:
Don't know off top of my head but pretty sure its under advanced
[Samsung Galaxy Nexus] wljohnson05:
Any way we can have being able to attach audio files as mms added. Not sure why that is gone anyway. I used to be able to send ringtones with my incredible, but haven't been able to with the nexus.

On a side note....I have never really been able to get the panorama camera to work(this rom or the factory stuff)...anyone else having issues with that?
[Samsung Galaxy Nexus] EyeOfTruth:
Reboot into recovery (CW) goto advance and it should be there.
[Samsung Galaxy Nexus] EyeOfTruth:
I just tried panorama on the latest version worked for me. I also did it under a stock rom

The attached document is from the latest gummy running francos 13.1
[Samsung Galaxy Nexus] Znomon:
Can someone please mirror the Rom? I can't download it from the nexus itself...
[Samsung Galaxy Nexus] tonm156:
Thanks. Strange I only have local bookmarks and have tried everything I could think of. I guess I will try re-flashing to see if that fixes it.
[Samsung Galaxy Nexus] kejar31:
lol clean your damn desk :P
[Samsung Galaxy Nexus] Dark Lazer:
So just to be clear, if I'm coming from the last version of this rom, I don't need to wipe data, but I DO need to flash the gapps file again? Or is this just when wiping data or coming from a different rom?
[Samsung Galaxy Nexus] tonm156:
FYI - the bookmark sync issue was not rom related, it was google account sync related. All good now.
[Samsung Galaxy Nexus] guitarshredder87:
You must install gapps with every update.
[Samsung Galaxy Nexus] mike216:
Anyone know what temp are normal? I get between 105-108 with normal to heavy use and just would like to know if that's ok or maybe if the UV could be causing this? Any help would be greatly appreciated
[Samsung Galaxy Nexus] Dark Lazer:
Okay thanks.
[Samsung Galaxy Nexus] hslayer:
so i just installed gummynex and i noticed that i can't press 4G toggle button from the status bar. I can press all the other toggle buttons except the 4g button. How can i fix this?
[Samsung Galaxy Nexus] EyeOfTruth:
If its a fresh install I would say wipe and reinstall. OR you might try downloading a touch sensor program <https://market.android.com/search?q=multitouch+test&c=apps>. Then you can see if maybe there is a small dead zone. I doubt there is but its worth the check.
[Samsung Galaxy Nexus] zman6900:
agreed on reverting to 1.5 kernel. I was getting amazing battery life with it and performance also. keep up the good work dude. :)
[Samsung Galaxy Nexus] mike216:
1.5 sleeps like a baby and performance like a monster!
[Samsung Galaxy Nexus] hslayer:
I noticed that Google map running in the back by itself, and it comes back even after I close it. Any idea why this is happening?
[Samsung Galaxy Nexus] b33zu:
Hey can we use aokps system mods on this rom? Anyone try it?
[Samsung Galaxy Nexus] gnexdude:
Thanks again for the update Kejar...love the new bootanimation too :)
[Samsung Galaxy Nexus] threepio:
Finally got around to installing this. VERY fast. very smooth rom. nicely done.
[Samsung Galaxy Nexus] Grims:
Thank you!
[Samsung Galaxy Nexus] mrdziuban:
Just flashed (with full data wipe this time) and had the same "Login failed" error when opening Maps. Solved the problem by opening latitude, choosing the notification to grant permissions, and allowing access. The same notification showed up when I opened Maps, but after allowing access the first time, it just said login failed again. For some reason, going through Latitude worked though.
[Samsung Galaxy Nexus] v2.2v:
Thanks bro
[Samsung Galaxy Nexus] donlad:
I figured I would let you know of the battery percentage mod bugs on the top right of the notification bar.

You'll notice that at 24%, the icon looks different than at 23%

Screenshots:
[Samsung Galaxy Nexus] kejar31:
ok gapps updated wallet is now fixed
[Samsung Galaxy Nexus] kejar31:
huh thanks for the heads up I need to work on these icons anyways.. next week expect an update to them..
[Samsung Galaxy Nexus] zman6900:
Very well done with this new release. Thanks soo much. BTW, loved the work you did for the Charge
[Samsung Galaxy Nexus] Grims:
I still get a maps signin error.
[Samsung Galaxy Nexus] rnagenetics:
I upgraded from 2.6 to 2.8. I did not add my accounts back in on the upgrade. Then I flashed 2.9 without wiping data. Afterwards I could not add my Google accounts. Had to wipe data and reflash 2.9.

Also had a lock up with hot plug governor.

Other then those issues been great so far.
[Samsung Galaxy Nexus] tysdad08:
Any one else have the bug that if the phone is turned off and u plug it in u get the battery with the lighting in the middle but it never goes away even if u unplug the phone? I have it and only way to get it to go away is pull the battery.
[Samsung Galaxy Nexus] Grims:
So is this working? I don't see how it could go that low, but it does freeze if I go lower
[Samsung Galaxy Nexus] frow86:
I had the same issue with maps. Open maps goto settings and click sign in. Click your account and it will want permissions. I think there are 3 its wants. After that it no longer pops up
[Samsung Galaxy Nexus] ihyln:
Apex kernel fixes that issue
[Samsung Galaxy Nexus] tysdad08:
Where can I find that kernel?
[Samsung Galaxy Nexus] ntantinan:
It's on the rootzwiki website. I like the kernel that came with the gummynex rom though it's faster.

Btw love the rom. It is my absolute favorite!
[Samsung Galaxy Nexus] daveseris:
After trying available roms, there is no doubt Gummy is the one. Been using since Thursday w/no issues. I did flash Francisco's kernel and if you want consistent quadrant scores averaging around 2700 ( I know, not the best indicator) give it a try. Great work Justin!! Merry Christmas.
[Samsung Galaxy Nexus] mrdziuban:
That would be pretty insane if those actually worked. I was running 1225/1125/1025/925/825 until I saw this and just decreased them significantly.

Anyone know if a widget/app exists to record the CPU voltage? I'm interested in seeing if the UV is actually working.
[Samsung Galaxy Nexus] diablospeed:
this seems to really be a nice ROM. i'm glad you are back on the samsung train.
[Samsung Galaxy Nexus] mastertwiz:
I'm trying to flash this ROM but I'm continually getting errors in the file (status 7). Any insights on this problem? Thanks.
[Samsung Galaxy Nexus] daveseris:
Check to see if you're on CWM 5.5.0.2. If so, try flashing CWM 5.5.0.4 via CWM. That should do it.
[Samsung Galaxy Nexus] Zzim:
I don't know if this is part of this ROM yet or not but could you remove software rendering? So the OS is always using the GPU to its full potential. I have issues with some emulators on this phone and I think its because of how android 4.0 uses the CPU/GPU.
[Samsung Galaxy Nexus] wljohnson05:
Yeah I can open it up and take the panorama, but it starts processing it and then just quits back to the camera. It has done that most of the time. I've taken like 1 panorama since I got the phone. I mean it's not a big deal because I don't use it often, I just wanted to know if it was my phone being dumb or if it was software.
[Samsung Galaxy Nexus] shimmishim:
One quirk I've found is that if you have an alarm set already (with the alarm clock icon) if you go into the gummy settings to hide it, it won't hide.

so you have to turn off the hide alarm clock setting in gummy settings. go into your alarm clock. turn off your alarm. go back to gummy and turn on the hide alarm clock setting. then when you go turn on your alarm clock, it won't show up.

Also I've found since 0.5.6 the battery life on this phone to be awesome. I'm averaging about 2-3% drain per hour.
[Samsung Galaxy Nexus] Kevin3328:
First off awesome awesome rom and coming soon a custom theme I'm building green gummy
[Samsung Galaxy Nexus] Tsoflyyup:
2-3% an hour? While sleeping or in use?
[Samsung Galaxy Nexus] Znomon:
I'm still getting this problem with my soft keys on modded dpi's. My current dpi is 240.
[Samsung Galaxy Nexus] shimmishim:
While asleep and not in use. With the older ones I was getting 4-5% per hour in sleep.
[Samsung Galaxy Nexus] Tsoflyyup:
I gotra figure something out....my phone sleeps great....but when im using it....the timers on! All i do is chat...mid to low brightness...i may data wipe n start over
[Samsung Galaxy Nexus] EyeOfTruth:
can we call it gumby, sorry I watched way to much gumby growing up and when I red green gummy I thought gumby.
[Samsung Galaxy Nexus] Juvenall:
I (almost) always do a full data wipe when updating my rom. Most problems I run into are quickly solved when I do, so if you've not tried that, give it a shot and report back. However, your screenshot puts the bulk of your battery drain on your screen. At almost 70% of your battery usage, that's clearly the killer here.

Could you pull up those stats again, then tap the graph, and post a screenshot of the new page it brings up? It will give more details on what's happening.
[Samsung Galaxy Nexus] Tsoflyyup:
Yea the screen...but i still dont think it should drain that quick...im only using gtalk n g+ a lil twitter here n there

Here ya go....yea maybe i need to try a full wipe n start over...
[Samsung Galaxy Nexus] Mr. Steve:
This is the cost of having such a huge, high resolution screen. Most people normally get around four hours of use with the screen on the entire time so what you're getting is to be expected.

Umm, one idea that may help with your battery life could be what governor you set the CPU to use. Which one are you using?
[Samsung Galaxy Nexus] Tsoflyyup:
I keep everything stock like the rom came
[Samsung Galaxy Nexus] Mr. Steve:
What you could try is this...

Download the latest stable version of Imoseyon's kernel (Right now GummyNex 0.6.5 has version 1.5, the newest version is 1.7.1.

http://rootzwiki.com/topic/13092-kernel-leankernel-minimalistic-kernel-171-12012/

Flash the zip file for 1.7.1 in Clockwork.

Then, set the governor to hotplug.

What hotplug does is when the system doesn't need the extra power, it shuts down CPU1 when you don't need it, effectively saving the energy that the second core would be using. It should, in theory, improve the battery life on your phone when the screen is no but you aren't doing anything that need a lot of power. Try that out and see how it goes.

EDIT: The reason I want you to update to the latest kernel is because the hotplug governor is not really that stable in 1.5, but it was greatly improved in 1.6.6 and 1.7.1 to work almost with no issues at all.
[Samsung Galaxy Nexus] Tsoflyyup:
Ok do u suggest i try this before doing a data reset? I tried hot plug a week ago and my phone start freezing....wha about the voltage settings i have no clue wha to do there...im afraid of frying the processor... but ur saying hotplug is safe on the 1.7.1 to try?
[Samsung Galaxy Nexus] Tsoflyyup:
And when flashing the 1.7.1 kernel do the typical wipe cache, dalvik, and batt stats?
[Samsung Galaxy Nexus] Mr. Steve:
1. Do before you do a data reset, save data reset as a last resort

2. Hotplugging got a major overall in the last week, it's really quite stable now.

3. You don't have to mess with the voltage settings if you don't want to.

4. When you flash the kernel wipe nothing, you don't have to at all.

5. Follow the golden rule, make a backup, not that I think anything will go wrong, but it can't hurt to have a safe backup in your pocket.
[Samsung Galaxy Nexus] Kevin3328:
Lol I'm down I actually thought of that myself.. it will be a bit b4 its released hopefully within the week
[Samsung Galaxy Nexus] Tsoflyyup:
Ok cool thanks for the feedback! Imma try this now and report back. I really appreciate this!
[Samsung Galaxy Nexus] Mr. Steve:
No problem, and if the hotplug doesn't work out then InteractiveX would be a good second choice.
[Samsung Galaxy Nexus] player911:
Just to clear things up, the default included kernel doesn't work with Hotplug even though its in the options?

Hotplug sounds like the way these dual core phones should have been programmed from day 1.

I'm running the latest Gummy. Couldn't resist the MIUI battery bar and custom lockscreen options.

A few things I've noticed. The Battery Icon selector popup menu is whack. And the lockscreen custom apps seem backwards on the actual lockscreen. #2 is on the left and #1 is on the right. Would be an easy fix by just swapping the numbers around on the graphics and menu items.

Pretty slick.
[Samsung Galaxy Nexus] UniqueNate:
Do you think a grid size could be added in to make up for the space that Google Search bar took/takes even after we remove it? The menu tab in the dock doesn't work in some sections even though there is the normal '3 doted' menu there.
