[Q] update to 4.0.4 battery - Nexus S Q&A, Help & Troubleshooting

Has anyone else been able to update their nexus s to 4.0.4 i flashed the update through cwm (but i dont have root anymore now) and im still having some battery problems after 20 minutes i was down to 84 % from 100, anyone else having battery issues still or is it fixed for some people?

Did you set the brightness in auto mode?

Ya my brightness is on auto, would that be killing it more?

It's only my opinion, I never had a battery drain but... just today I set the brightness on auto and guess what? Battery drain.
Try this: disable auto brightness, reboot (important: seems that disable without a reboot of the phone, didn't works as a workaroud of battery drain) your phone and give it a try.

Ok ill give that a try then hopefully it will help thanks

don't forget to tell us if it works for you or not!

Ok so i turned off outo bright and put down the screen brightness pretty low and it does seem to be helping a bit im still seeing more battery drain but not as much with auto bright turned off

That battery drain is very high. My Nexus S drops 2-3% per hour while idle. With flight mode enabled it only drops 2-3% overnight. I would suggest install CPUSpy or similar to check your device is going into deep sleep. You could have an application causing a wake lock and not allowing sleep.

Battery draining while sleeping? Try this!

This works in VegaN - YMMV...
Settings -> Wireless settings -> then hit the menu button, and choose "Advanced", then select "WiFi Sleep policy" (It was set to NEVER!)
Spare parts showed (via 'Spare Parts' app) that the WiFi was on 100% of the time - even while sleeping..
I'll give this a try tonight when I go to sleep.
I like to leave it at "never" so that there is no delay upon wake up to connect to wifi. With the table in use (vs. sleeping) the battery life is so long; almost 10 hours, I don't worry about a little battery drain while sleeping. Just connect it to the charger once a day or less.

You get a 'little' battery drain while sleeping? If I leave my gtab unplugged overnight, it loses about 4% per hour.. or about 30% overnight. That's why I'm trying different things. 30% overnight isn't a little to me -- it's way too much.
A tablet like this should all but go into a state of suspended animation while sleeping...
30%, really? That sounds as if there's something else going on rather than just wifi draining.
Edit- Some thoughts. There are some apps that require permission to update or snag some ads from the net and operate on their own.
Go take a look at what you have installed and look at your screen timeout settings.
If you have CWM and can get to recovery, wipe battery settings and then reboot/charge. Some people drain completely then charge to get to 100%. Some threads seem to show this is a Vegan issue. (Mine gets to 97 tops but as long as battery life is not affected, I'm good)

Just curios, why would you leave it on all night when it will never be used? it only takes a minute to boot in the morning when you turn it on.

I leave it in sleep mode because its my alarm clock. I also now leave it plugged in.
I've tried draining the battery then resetting stats in clockwork. If tried about every variation of doing that I can think of short of waiving a dead chicken over it.

I've left mine on and unplugged(it went to sleep) for 3 or 4 days and come back with battery still. 30% overnight seems odd.

I think you might be right, because I used Cyanogen Mod for a month and a half and had no issue like this. Now I am using TNT Lite 4.2.4 and I am still having no battery life issue.
Also I have never been not able to charge my Tab to 100%. So I may suggest that you guys try switching to cyanogen mod or tnt lite.

[Q] Battery loss during standby. . .

Is anybody seeing heavy battery loss during standby mode?
On average my TF is losing between 3.5 and 5% battery in standby mode. I have done a few tests with and with out airplane mode and it does not change.
I currently have an RMA setup with ASUS but I dont want to have to send it back and wait 14 days, so I wanted to reach out here first.
Thanks in advance,
Brandon
Every device I've ever owned has lost power during standby. That's the tradeoff. Otherwise, you could, you know...turn it off?
Windows has that nice "hibernate" hybrid.
It's totally not worth an RMA...don't let your OCD win.
There are a few processes that run in the background like Android OS, WiFi, keyboard etc. It needs to be reactive to certain signals so it can't be off completely. The iPad has amazing stand-by times but I don't know why. I just saw it when I borrowed one for a day from a friend.
I would NOT RMA my device unless it's a significant drop in battery life (>10%/h); it's just the way it is mate!
But what I realized is after I rooted, installed SetCPU and set the governor to ondemand the battery life has increased significantly. It idles at 216MHz now.
mine doesn't have a great standby time either, pretty bad actually when you compare it to my xoom. however its an issue that should be fixed with a software update and it shouldn't require an rma.

Check if you have your Wifi on sleep also?? Depending on number of applications that you use for updating it might be using your battery.
There are a number of other threads already discussing the issue of battery life in standby, but here's my conclusion: the TF has an issue with wifi that if you set it to stay on while the TF's screen is off (a setting in the wifi section of system settings), it burns quite a bit of battery while on standby. If you set it to turn off when the screen is off, then it doesn't.
I know this is a bug with the TF because the Xoom does not exhibit this behavior. It burns less than .5%/hour when on standby with wifi set to stay on when the screen is off. The TF gets this same performance (<.5%/hour burn) on standby only if wifi is set to turn off. Otherwise, I'm getting the same as you: around 3.5%/hour burn rate.
I'm assuming that the TF's wifi just doesn't enter whatever low-power state it's supposed to enter while on standby. My second assumption is that this is something that will get fixed in an update.

I just turn on airplane mode when I know it is going to sit, and it burns about 1% an hour.

Is there an adjustment for the Wifi and/or app settings. In general the second or third largest power consumer in these devices is the radios. The radio needs to be powered up whenever a connection needs data. This can be for keep alive messages that verify the existence of a wifi connection to an access point, or from an app such as gmail, calendar, etc. checking for new data. In any case there may be settings that allow one to decrease the frequency of these operations.

FYI, I did a few tests with airplane mode on and I was still losing around 3.5%-5% battery life.
I did do a few more tests, and my most recent test I found interesting.
I use my TF as usual and had a few applications running, I then turned off the screen and let it sit for an hour and 4% battery life was used.
Then I powered down my TF fully, then I powered it back up and turned off the screen. (Currently the TF is up and running but no applications have been opened aside from backround apps Syncing).
I put the TF into standby (turned off the screen) at 1:37 am and I had 53% battery life.
I checked on the TF in the morning at 8:51am, and I had 51% battery life.
So in just over 7 hours my TF only used 2% battery life in standby which is a very acceptable range.
Conclusion, what ever apps we are opening and using under normal use are not being fully closed out, and are running in the backround, not the backround services as per the airplane mode test.
I will do a few more tests tommorrow, I hope this helps and I look forward to others feedback!

Brandon - Please check out yours with wifi set to turn off when the screen is off. In all of my testing (similar to yours), that made the difference between great standby performance (<.5%/hour) and not-so-great (3.5%/hour or more). Nothing else seemed to matter, including manually turning off just about every app that normally runs in the background and verifying that they stayed off.
Hopefully soon Asus will also fix the battery stats bug so that we can see what apps/system components are actually using power on standby. Or they'll just fix wifi so that it sleeps as it should.

I have already done the tests with WIFI turned off and also with the TF in Airplane Mode.
So far the only time I have gotten great standby time was when I rebooted my TF and did not open any applications. (WIFI was on FYI)
Brandon
so, the last two night i've gotten great result from stand by mode. The first night i went and killed couple of programs, before putting in AP mode for the night. 12:45 am till 9:00 am from 78% 75%. Last night at 12:00am had 34% this morning at 8:00 it dropdown to 32%.
I took a screenshot of the battery usage after waking up in the morning. Wifi was left on with the sleep policy set to sleep on screen off. It seems to turn back on intermittently but the awake bar seems to happen more often the longer it is in sleep. Is that meant to happen? What does awake signify? That the screen is on?
background data probably running in the background
like weather updates to it to refresh every 4 hours or something
its weird though, towards the right theres like 2 times where the device is awake for long periods of time :S

Would you try "Task killer" for decreasing battery loss?
My battery seems to be dying alot quicker now I have the dock. Hopefully a new firmware will come out that'll lower the battery consumption of the dock when its in standby.

[Q] Can't figure out what's eating my tf700's battery?

Hi all,
My new tf700's battery is draining while sleeping.
I tried Don's airplane mode, unchecking Activate Wi-Fi while screen is off, checking disconnect Wi-Fi while screen is off, yet nothing works!
~5% drain per 7 hours.
The battery stats show that ~11% of the system resources go to waste because of "System Idle"...
This is despairing.
Please help.
Even a device that is sleeping consumes power. Personally, I do not think that about 5% per 7 hours is that bad -- is it? I would recommend installing BetterBatteryStats and then have a few charging cycles to see what's happening inside. (It may be an app that's going amok, and that may not be reproducible with a single run.) The standard Android battery report I do not trust.
5⅝ isn't that bad really. There are some extra power saving options and if rooted you can enable deep sleep.That'll give you 1% - 2% overnight.
What's your screen set to? IPs or IPS+?
Which CPU mode?
Is it very cold? Cold drains a battery faster.

IP (not IPS+).

How can u enable deep sleep in root?

Big Overnight Battery Drain

The first screenshot is my battery life and as you can see Doze was applied but it still drained 10% in 8 hours. In the second screenshot of Better Battery Stats, it shows I have a lot of the phone being awake while the screen is off.
How can I figure out what is causing it to be awake and fix it?
Please let me know if you need other sections of battery stats or anything. Thanks

same things , im on on 10.3. it was pretty good during fresh install like 2 % in 6-7 hr. now 10% overnight drain everything off
PlusBeat installed? Had the same issue. No drain with it under 9, high drain under 10. BBS did not show this app. Found it only after freezing one app after another.
I really can't understand how you guys end up with these drains. Since I rooted I've taken about 7 updates to 10.0.2 , never wiped my phone and never encounter that type of idle drain. Check my screenshot it shows 0% drain in 6hrs with only 10% deep sleep which makes no sense at all. What's crazy is im trying to perform a battery test to get to 10hrs SOT with regular use but my uptime won't be accounted for in the battery menu because it starts calculating after you lose one percent. Thus the discrepancy in the screenshots
Some app is preventing your device from going into deep sleep. Facebook was the culprit for me.
Do you have a custom kernel installed? Something changed in a recent update & there's a service that goes haywire if you have a custom kernel & keeps one CPU core at 100% constantly. I found it in system logs as "vendor.oneplus.hardware.brain". My idle drain was over 4%/hr till I figured it out. See this post for how to stop it:

Question Standby Drain Exynos

How is everyones standby Drain?
Mines appaling. Even over night it drains about %6 with nothing running and airplane mode on! I've already reset it since the April update and cleared cache etc. SOT is good enough but obviously I will manage less of that with the poor standby drain.
That's about the same for me. 7 or 8% but no airplane mode
I have bixby routine that enables power save mode and disables wifi and mobile data from 22h00 until 06h30 the next day...I loose perhaps 2-3% for that period. Without power save I loose for the same period of time 6-9%
~3% overnight drain. No flight mode.
I lose around 4-5% in 8hrs. That is with WIFI on and Flight mode OFF.
mine has gone down hill over the past few days - not sure - but went from 5% overnight to 15% - didnt change anything - just installed the app updates that were available so am thinking something with an app - but nothing showing up in the battery life check
2-3% overnight drain with everything on, get the galaxy max hz app and enable doze and powersaver mode when screen is off, before mine was 6-8% a night now its 2-3%
1% per hour on average when left idle overnight with wifi on

Is this only in the payed version, because my issue at the moment with this app is, when my phone goes into battery saving mode, when it comes back out (with bixby routine) the phone is stuck in 60 hz. Basically, i have to manually set up the adaptive refresh rate everytime.
Is this problem gone with the payed version? Or am i doing something wrong.
Cheers
