Tablet idle? Sleep mode? - Nexus 7 (2013) Q&A

As an experiment, I left my tablet on overnight with %100 battery left. Turned wifi off and woke up 9 hours later and it is now at %81. So basically with no usage at all, just left on without connection %19 was used. Is this not sleep mode?
Is this normal? I understand if I left it on with wifi on overnight, sure, %19 sounds decent.
Any ideas?

Not decent. Something is waking up your device. I lose 0% overnight with WiFi off. Maybe just 1-3% with WiFi on

Yikes ok thanks

You folks sure have a different expectation than I do. Every tablet I have owned had to be charged every day or two. Only my Sony ereader would go two weeks between, and that is a CMOS device.
Good luck getting your hundred days between charges. I would just turn the device off.

recreate your experiment by putting the tablet in airplane mode instead of just turning off wifi. see if there's a difference.

Arrived at work at 9 AM. Left my N7 in my carry bag on in sleep mode. 98% when I last saw it. 8 hours 15 minutes late it's at 98%. Damn good!

My n7 is at 130 hours uptime on this charge cycle, with 7 hours screen time (but almost out of battery). You definitely shouldn't expect to have to charge it every 1-2 days if you are mostly idling.

I have used 2 other tablets (Galaxy Tab 10.1, Asus Memo pad) that would drop about 4-5% per day while not in use.

Tried airplane mode on. Didn't help. Battery life on stand-by was still 1-2% per hour.

Are those with the drain "ROOTED"? I unrooted my device and don't see any drain anymore. I also removed HD widgets...
I am not sure if it's the rooting part...

battery life

anyone else having outstanding battery life with this phone?? I am at 18 percent after 17 hours i honestly can't believe this battery life is this good. amazing.
---------- Post added at 09:49 PM ---------- Previous post was at 09:48 PM ----------
btw when i got it yesterday i let the battery run all the way down then charged it all the way back up it at around 1 yesterday central time ran it all the way down and charged it all the way back up around 7 pm and it's still on the same charge. and i have been using the hell out of it (no 4g though)
I only got 7.5 hrs today
I got 12 hours today, HOWEVER, 8 of those hours were with music playing none stop and 1 hour of internet while music was playing. Didn't touch a charger once. My EVO, rooted with godmode and freedom kernal still had to be charged at lunch to last throughtout my 10 hour shift.
I love this phone.
I had a weird issue just now. Battery was at 26 percent. Did a reboot by holding the power button down for 8 seconds or whatever it is. When it booted back up about 30 seconds later i had 10 percent battery. anyone else have this happen?

Since today was back to work day I decided to test the ET in a "real world usage scenario." All radios were on, including Bluetooth and Moar-Geez. I had sync enabled and hourly, including a push E-mail account. During the "beefy part," of the day, meaning 8am - 3pm, I was using moderate to heavy. During the downtime between 2pm - 5pm, I was using heavily and from 5pm - 8pm, there was moderate usage. So, I came home and right before plugging the phone into the charger I was at 40% battery on 15 hours. I am stoked. It is good. Zen.
You guys should calibrate your battery. Let the phone charge to 100%, run the app, unplug your phone.
This will wipe your battery stats and SHOULD give you a pretty accurate description of where you stand. We did flash a new kernel, and that can take some time for the system to get used to it. That's what I've learned from my Evo anyways.

This happened to me, but it went from about 45% to 20% after I reset. However, it took for ever for it to go down to 19%, 18% and I still had about 17% when I plugged it in around 11p.m. after taking off the charger around 7:30a.m. That was with a little over 3 hours of on screen time. I was surfing the web, about 100 texts, xda, about 10 mintues of vid games. I had skype running in the back ground most of the day. I had Wifi on all day and connected about 90% of the time. I didn't have GPS, 4G, or Bluetooth on. That's pretty damn good. I think the drop must have been a software issue.....?
from 7:30am - 12:48, I'm currently @ 72% from full charge.
Not as good as i hoped it would be.
Could it be from Launcher Pro?
my evo 4g would get to 50% from 7:30-5:30.
I dont have my 4g or bluetooth conected. just 3g data.
Not too good from me. 2h49m screen time only have 20% left ....

My battery life has been killer since day 1. Unplugged Saturday night at 8pm and when I woke up on Monday morning I was at 5% left. Over a day of use is amazing compared to my old hero and the evo 3d I test drove for a month.
Amazon?
Out of curiosity, do the people who get astoundingly good battery life have Amazon's app store installed?
On my Evo 4G I used to sometimes get up to 48 hours on a charge. Then it went down considerably and I could never figure out why. Even a new battery didn't work. I uninstalled a bunch of my key background apps like Settings Profiles but they didn't do the trick either.
The Amazon App Store runs poorly at best. Thus I always wondered if it could be the culprit.
Coming from the OG Epic, the ET's battery life is amazing. I haven't yet needed to reboot my phone due to the battery problems I've been hearing about. *knocks on wood*

Abnormal battery life on stock 4.0.2?

Lately, I noticed my battery has been dying much faster than normal. I got the phone maybe like 3 weeks ago, and it was lasting longer. I'm not sure if it's some app I downloaded or just the bad radios in 4.0.2 causing me to keep searching for signal, but it's definitely impacted how much I use my phone.
Anyone know what's going on? Or if theres some known issue with this?
Attached are some pictures of the running applications and the battery charts.
8.5hrs with 31% is pretty good to me.
You should look at my battery, 5hrs down to 16% (I have all active sync disabled, turned of 4G AND screen brightness only at like 5% for the entire time.)
*sigh*
If you look that is almost all standby time, which should be lasting way longer.
That's not horrible but you should look into what's waking up your phone so often.
Whats your screen-on time there? It looks like its really low.

It was at about 25 minutes of screen-on, but the keep-awake on the android OS was an hour. Could this be the culprit?

Well look at your "awake" bar. Something is consistently waking the phone. Just syncing email etc wouldn't keep it awake that long. Its another app.
Use something like "BetterBatteryStats" to monitor microscopically whats waking the device.
Thanks, I'll use that app and post results.
Another thing is I looked at the cell standby, and it told me that 25% of the time it did not have signal. Could searching for signal cause the intense battery usage?

Looks like you had some times of bad signal based on your screenshots, but not the entire time.
Bottom line your phone should be idling much better than that. Granted I'm on GSM and not LTE, but when I turn off my screen and let it idle (i.e. forget to plug it in over night) the graph is almost flat. It will idle forever. Yours is not seeming to do that.
reboot..
I reboot my phone twice a week. It works really good.
Battery after a reboot and 9 hours standby. 96%
Without a reboot 70%
Big difference..

After much testing, I found out the anti-theft feature in Avast! is causing the massive battery drain. It prevents the phone from going to sleep.
Ow that sucks well out with that app, I use avg very good. Also I get an average battery usage of 3hours screen on time.
That's with most syncs on also wifi and GPS are always on.
Usually its bad apps that can't handle ics
Sent from my Galaxy Nexus using xda premium
I'm also using Avast but I think my awake pattern fairly falls in line with the screen on pattern. Twice out of the 2 months I've owned my nexus the battery has drained really fast - normally I will get about 28 hours. Any ideas?

Surely not normal??

Running Liquid 1.3 Rom with Franco Kernel
48% Battery left
1h47min on battery
1h15min screen on time
Brightness is at approx 70%
No wallpaper and therefore black screen

Surely this isn't normal?? I've tried various other roms and its the same.
I dunno but I just got this phone today, stock and rooted. My battery dropped from 100% to 90% in about 20 minutes. Not a good sign...
I thought my old HTC Desire HD was bad but this is in a different league. I'm on 39% now!
I get about 14 hours with moderate usage and about 3.5 hours of screen on time before the phone dies.
Try using CPUSpy & BetterBatteryStats app to see if the phone goes to deep sleep when screen is off.

Were u using wifi? If not and on a 4g connection the whole time then u should not be surprised by that battery percentage. 2 hours of screen on time with constant 4g is pretty typical.

That looks about normal. You have a 4.65" display, pumping a lot of juice into it. Turn the brightness down to %50 or less.

new battery

Hi,
I got a new battery for my GS3. There is a lot of conflicting info out there. Do I first charge it right away before using the phone or do I use it until it dies and then charge it?
Thanks
I always thought it was a myth until I tried it out. My sister's phone had the same things as mine all stock and widgets are the same. I drained my battery right away while she kept her battery full. The result? Hers averaged 4 hours screen on while mine is 2 hours

The let it die first then start charging is a myth... just research it, there are numerous sites claiming the results will diminish and kill Li-Ion batteries faster. Just use it as normal.
How does she get 4 hours of screen time. What is she doing during that time? I can barely get 2 hours but that includes about 2 hours of talk time. Does my usage sound normal or on the low side? Based on what I read here on xda I was expecting better battery life.
We would need more info on your use and what not, after a full days use post screen shots of your use time awake time and call time. We also need to know if you're stock rom and what your signal is like.
My signal is always full bars 4g. I am 100 percent stock. For example right now I have 37% left after 11 hours of uptime. This includes 1 hr screen time and 1.5 talk time. I did nothing but talk email and text today. I did about 20 emails and 150 texts. Is this on the low side? This is why I had t-mobile send me a new battery and am considering trying it.

I would call that kinda normal, I don't talk on the phone for more then 25 minutes per day, and send about the same amount of text and data massages (whatsapp and gtalk) few emails, I average about 3.5-4 hours through out the day... If I were to talk on the phone I'm guessing I'd be getting around the same as you, and I have a spare battery that gets about the same performance.
What percent are u left with by the end of the day once u get the 3.5-4 hours? Now I'm wondering if I'm being paranoid. And if there's a point of trying a new battery if u think my usage is somewhat normal.
On average while stock I'd say 20ish percent... no on non stock roms I play with my phone more and use more battery haha... that's up to you I've seen reports in between both of ours from 7 hours of on screen time to people with barely 2 on screen time. Everyone uses their phone differently.

Battery life?

What sort of battery life are you all seeing with this years note? come from the ipad 3 where i usually saw 10-11 hours screen time and 2-3d standby, today is the first time ive had it from 100% and i only lasted 6 hours screentime with 7 hours overall on time, i still havent run it down completely yet but surely i should be getting more than this?
Its such a shame because i love it so much, but i cant deal with this short battery life
It's much better than that. I found it better after a couple of charges. I rooted mine and deleted or froze b.oatware and I get 13 hours heavy use

I came from an ipad 3 as well and had the same problem until I disabled several apps, turned off GPS, etc and over the long weekend I was getting ~12 hours of web surfing.
I haven't rooted yet so that should be a number that can improve. I'm sorta trying to wait for a root that doesn't trip knox. I don't want a custom rom so no reason to install a bootloader and lose my warranty if I can be patient. Tried Cydia Impactor but I had already upgraded to MK1. I'm wondering if the shipping rom (P600XXUAMIE) might have the 4.3 vulnerabilities unpatched.

I thought it was more, but looking at the list.. go to settings, General, Application Manager, select the prinstalled apps you don't want running all the time and click Turn Off. I've turned off BlurbCheckout, Businessweek+, NYTimes, Polaris Office, Screen Saver and Twitter. I think more important was turning off GPS, Screen Rotation, Bluetooth, Reading Mode, Smart Stay, Smart Pause, Smart Scroll, Auto Brightness then adjusting the screen brightness to something a bit less retina searing than the default.

I've had mine since Saturday soooo, 5 days now. I get easily 10-11 hours of screen time. I loose about 1% per 8-9 hours in stand by and i loose about 9% per hour of video streaming from either my Netflix, HBO GO, or Slingbox account and that's with brightness about or just above 50%. I'm also NOT rooted yet. Totally stock with just certain apps turned off and i restrict a lot of the background data on individual apps that i don't need running background data
Have you guys try using this damn thing at 100% while indoors? It hurts the eyes with a white screen.

Hmm, I think I misspoke about the background data on this tablet. I do that religious with my phones (Bionic, GS4) but I went to look at what i did and there is no option to turn off background data. I would normally go to settings>data usage and tap whatever app and the check "restrict background data". I must have thought I did that on this tablet but obviously not.
i think the battery life is great on my tablet - i dont game with it - today it has been running for 13 hours 48 minutes with 5 hours and 48 minutes of screen on time and battery is at 52% - not rooted yet - i have everything i dont use turned off ( ie. smart stay/scroll, air view ) and running nova laucher prime and dont use power savings mode
Face it - it's nowhere near ipads. That's my biggest concern.

I dunno, doing pretty good over here. Rooted, but have no froze anything. Only rooted to get gameCIH installed screen is between 25% and 50% brightness depending on what im doing or where i am. I mostly just use it for playing a few games here and there, taking notes during lectures.. etc. This is about typical, sometimes I get a little less, screen brightness seems to play a huge role in battery drain (obviously) but ive never run it dead during the day.. ever. I start every day with 100% charge and dont usually plug it in till I go to bed. If I have a charger around and im not doing anything ill plug it in (I mean.. why not) but I don't ever have to "worry" about it going dead on me.
I'm currently on 9 hours of battery time, probably at least 4-5 hours of that is screen on time reading comics or doing sketchbook pro pictures.
Battery is on 46%.
So yeh, battery is fine. Brightness is about 30%.

Right... It's better then an IPad. I doubt the IPads beat 11-12 hours of screen time at roughly 50% brightness and an IPad has a smaller screen and less pixels to power.

Hi all, I just bought this tablet, I have not turn it on yet...
Do I have to charge the device fully before turning on like some cell phones are?! or I can just start using it right away?!
and what kind of battery it does?! how's the charging process?! should I wait for it to be fully discharged, and then charge it to 100 percent?! or should I keep it between 40 to 80 percent to save the battery life...

and what kind of battery it does?! how's the charging process?! should I wait for it to be fully discharged, and then charge it to 100 percent?! or should I keep it between 40 to 80 percent to save the battery life...
in a nut shell, if you have any forum or link or information that could help, please share

Dude, just turn it on and use it. The days of cycling a batter (let it drain and then charge to full) were over in the 90's with Ni-Cad batteries.. these do not develop a memory. From dead, the tab will take 5-6 hours to charge with supplied charger and in the wall. Using it while charging will still cause it to lose battery but a a much slower rate.
