[Q] How to see the battery current? - Samsung Galaxy Nexus

Hi
Like the title said, how can we see it? i am having a drainage issue (more than 40% drain in 8h on standby!)
I tried using Current Widget but it shows no data on my galaxy nexus. Also, i used Battery monitor widget (free edition from the market) but the numbers showed on standby (No auto sync, no wifi) are way too high ( around 100 mA!) is it normal? My old HTC desire will only display 4-6 mA! does the widget work properly on the galaxy nexus?
My phone has a stock rom, no apps installed (except for Titanium backup and the widget).
I looked at the battery stats, and there is no awake time, nothing..
Any help?

I have the same problems. CurrentWidget doesn't show widget in the widget list Battery Monitor Widget shows unusually high current (sometime 1000+ mah). I wonder if this phone supports reading current properly. Any solution?

Are you rebooting after widget install ? Sometimes you have to for them to show in the app drawer

Current Widget is showed in the widget list but it reports no data.. I checked the path sys/class/power_supply/battery/ and the "current_now" script is not present.. Maybe that's why there is no reading for the current mA in the Gnex?

Conserving battery, Hungry apps etc

Hey guys, thought it might be a good idea to share with each other what apps/settings are mauling their battery life...
Personally at the advice of beards, I used systempanel app to try and monitor app cpu usage etc.
I was experiencing large battery drain overnight, so I decided to leave it running for 1 night. By the morning I had lost about 30 or 40% of battery and systempanel told me that Fancy Widget was using about 11 or 12% avg of cpu (if I remember correctly).
I removed Fancy Widget, turned off Data (with APNswitch) and also stopped systempanel (which prob contributed some of the usage itself) when I went to sleep the other night and the batt was at 40% usage. In the morning I turned on my phone and was greatly surprised to learn that the phone was STILL AT 40%... didn't even lose 1% wooooot
So.. I'd like to put my suggestions out
Batt hungry apps: FancyWidget (maybe...? but I'm surprised that other people don't seem to have a problem so maybe its my human error?)
Phone settings:
Data:3G data seems to consumes a lot!!!
I suggest leaving on 2G if you want to keep auto syncing apps etc, and swapping to 3G when you really need the speed (browsing/downloading).
If you want to totally maximise battery usage, turn off data completely every time you put the phone on standby, and turn off all autosyncing apps.
I also believe Wifi consumes less battery than 3G usage, although I haven't done any serious testing, I managed to use wifi on and off for about 5 hours at a lanning event and I still had a fair bit of batt left.
Recommended apps:
I recommend APNswitch to turn off data. I like it because you can use it as an app, not just a widget, as I've found all the APN widgets too be ugly. It also uses the notification bar wisely
Other experiences:
According to systempanel, samsung widgets (feed, buddies, daily briefing) all consume very little CPU (less than other widgets in my experience. I've kept them all as they seem beautiful to me
To XDA members, anyone else experience bad batt life with fancy widget?
Please feel free to critisize any of my claims, I hope we can help each other out with sharing battery life tips, good/bad apps etc.
EDIT:
Wallpapers:(thanks gadjet0)
Live wallpapers seem to consume a lot. Also having read discussion about the power consumption of oleds, I put a pure black background on my device. Whether it's actually reducing power or not I have no scientific evidence.
Thanks should pin this!

Have you tried any live wallpaper, I got the feeling that they put a drain on the battery!
Yes, all its true what have writed oswade. I was make this thing with my Galaxy, and battery life have very growing...
Regards
also try tasker, I have set profiles to put phone into airplane mode at night, during day the data is off, but comes on every 15 mins or when the screen is turned on (like juicedefender i think its called) works brilliantly and conserves battery.
I can unlpug phone at 5am and still have around 60% at 9pm with light usage, while before I would get to evening and battery would be close to dead!
Glad that I'm not the only ones.. I suffered quite bad. Full charge ard 6pm..was playing robo zone for an 1hr+. Batt left 50%. Arghh..
Does black or darker background uses more batt?
I'm using beautiful widget.

Couldn't figure that out either... probably need to use a task-killer or reboot.
So what do you recommand (or anybody else) to replace Fancy Widget ?
I don't really want a HTC like Clock but I want a digital clock like this ?
Beautiful Widget for exemple ?
And i don't know why an app which automatically turn on/off the 3G when ur using the brownser/market doesn't exist already ? That will be great !!!
What's wrong with fancywidget? Seems fine on my device.
If using Juicedefender,do I still need Advanced Task Killer?
Then What?
Hi!
We have industry best hardware configuration.
But we
1) can not Use live wallpapers
2) can not Use 3G for many hours
3) can not Use considerable number of applications from the market
4) can not watch two full length movies
5) etc.................
If you want above
1) Purchase additional battery and put in your pocket
2) Power adapter/ Travel adapter always carry with u
If you are roaming for more than six hours, then it's bad.
this is not only for Galaxy S most of the samart phones fall in this.
What can we do????????

Dude, I have a Samsung Galaxy Ace
As soon as I got it I installed fancy widget and some other programs. My phone was lasting only 6 hours. I sync to corporate, gmail, facebook and a few others. At first I thought 'bad phone'. I uninstalled Fancy Widget last night and voila my phone is fine. It'll last a day+ now.
What the hell is wrong with that app?? Why does it need so much compute? Its just a widget that shows time??

Stupid Battery Drain

Follow the guide on battery drain i installed current widget, im on RevolutionHD rom (fresh install after wipe) nothing installed apart from CurrentWidget im getting 385mA just with my phone sat there - Wifi is off, bluetooth is off data network in on.
Is something wrong?
Now running at 404mA with no other apps installed and turned off as much as i could, coming from sleep to view the widget...
How much it drains when asleep?

you can post your currentwidget log file here.
it's normal to have 200,300,400 if you play with your phone. the consumption is come from sync, screen brightness, or gps.
you can only have below 10mA if you put your phone in idle(with screen off) at least 1 hour, and you can check your log file back.
btw, if you dont know how to check the log file, so to currentwidget apps (not the widget) -> view log. post it here so other can help.
yep, when your phone is working with screen on, it's normal to have 300-400mA.
if your phone idle with screen off, it can below 10mA, you can check the currentwidget log.
Hi,
The currentwidget log stops on mine (Gingerbread) when the screen is Off. Weird!
But it logs the current when screen is off on my Desire (Froyo). It shows 5mA, with my SetCPU settings.
Any idea why Current Widget stops working in Gingerbread screen off?
What is the app name to know about the battery. And second thing, anybody knows here how to free mobile rom memory I have just 200 left even all applicable are moved to sd card... Plz help to increase the memory...????

Current widget doesn't show me the mAh

hy guys i have a problem with this widget it shows correctly temerature mV percentage but when i switch to the consumption of mA it shows no data! in every rom i tried it will shows the same thing anyone can help me?
some screenshot
Have the same Problem
The Galaxy Nexus doesn't monitor this parameter, so the widget has no data to draw from. It was very frustrating to learn when we were trying to verify the force fast AC charging mode. Sorry.

NCX kernel & battery life....?

Has anyone experienced their advertised battery life??? I can barely squeeze out 2 hours screen time on a full charge?
Currently using slimICS

I have never used that kernel myself but I would recommend a 4.1 sense rom (ARHD 9 is good and bugless). The use better battery stats to get rid of kernel wake locks and partial wake locks. Find a good screen brightness for yourself and turn off all not needed sounds. Wifi, data, but, gps, Facebook, Gmail, gmaps, and others can be a constant battery drain sometimes. No app is ever perfect (sometimes causes massive battery drain) but finding an alternative that works better is always great. Also let the kernel run for a couple days and it tends to fix most of the battery issues itself.
Any more info could easy be found with a search
I can do about 3-8 hours of on screen time depending on what I do. Like reading black and white text could do me 8 hours while heavy Web searching or calling or gaming could do me 3 hours

Is there a way to turn off Facebook in the background completely? I turned off notifications and location services from within the facebook app..but its always listed in the "Apps currently running" menu.

I find the Facebook app useful so keep with it only way to completely disable it is to uninstall it and use the mobile version of Facebook instead or tinfoil Facebook app on the market which is just like using the mobile version.

Are the native battery stats accurate?

Hey guys,
I wanted to know if the native stock Battery stats (under settings) considered accurate.
I suspect that a certain app drains my battery, though I cannot see it under the Battery stats menu.
Is there any chance an app drains a lot of battery and it's still won't appear under this menu?
Thanks
Tom.
I use it only for total uptime and screen on time. Other is near useless. It always show similar stat whenever you battery draining fast or not.

Not in the slightest when it comes to which app is using what. Get BMP from the play store to check wakelocks and such.
I too only use it for the total uptime and screen time. For specific app usage I use Betterbatterystats and android tuner, both paid.
