Read here how many users complain about slow charges. Theres a full thread in n7 general about issue. Mine charges sometimes in 4 or 4 hours but thats the best i get. Maybe theres some issues with the tab itself showing battery status because sometimes it discharges after 4 or 5 hours screen time and sometimes after 7 or 8... using youtube only
[Nexus 7 General] hassam_tariq2003:
REALLY......mine always takes more than that....it take 3-4 hours to charge FROM 0-100% since the day it came.......!!!
[Nexus 7 General] testadeferro:
2 hours for a 4300 mah battery you must have a nuclear charger! Lol
[Nexus 7 General] mssam:
I don't know exactly how long my N7 takes to charge from a low percentage to 100% because I usually charge it at night when I'm finished using it; and it is off, but these HOURS to fully charge seem kind of high to me. I might have to look into testing the charge time through a post that was suggested a couple of post back. My charge times seem to be within an hour or so using the cord and adapter that came with the N7. I don't think the N7 charges at 2mah like the ipad does (from what I have read), but charges at a lower rate, but not quite as low as the Gnex (which if I remember correctly is like 500mah). A little post from some place else to help shed a little light on the charging times...

[Nexus 7 General] iAndroidOS:
Can someone tell me if my battery drain is normal or not ? I was playing super stickman golf 2 for 21 mins, and got a 9% decrease. When i browse generally on the web, i get about 1% decrease for every 5-7 (maybe 8) mins spent browsing the web. I'm using stock 4.3 (rooted of course, and with minor build.prop tweaks). Is this battery drain to be expected or do i need to flash a custom kernel and UV/UC ?
[Nexus 7 General] Dark Jedi:
Playing a game is more intense than surfing the web. Its normal but you could flash a custom kernel but doubt you will see and improvement
[Nexus 7 General] hassam_tariq2003:
I had approximately the same battery drain on 4.3 stock unrooted........then i flashed cleanrom (4.3) and undervolted my device....it went to 10-15 mins per 1% battery...also i kept the screen brightness at auto...
[Nexus 7 General] khaytsus:
So you're claiming 16-25 hours screen-on time. You're very confused. The most screen-on time I've heard from a N7 is VERY light usage, and in the 8 hour range.
[Nexus 7 General] hassam_tariq2003:
Not exactly......once the battery went below 55%....the decreasing speed increases to 1% per 5mins.....and gets lower and lower with usage...
[Nexus 7 General] testadeferro:
I saw 9 hours screentime with faux kernel and smooth rom once surfing the web in low brightness. In android 4.2.2 jdq39. After that forget it. And what really consumes battery is gapps. I use to remove all exept market. Even gmail app takes a lot of juice. Better using browser to read mail.
[Nexus 7 General] Hypoxic1:
USB OTG works fine on my Nexus 7 with 4.3. I use it for controlling my DSLR camera, as I did with 4.2.2. So yes, OTG works on 4.3 just as it did with 4.2.2 on the "old" Nexus 7.
[Nexus 7 General] hassam_tariq2003:
TRY the Pacman rom with android 4.3...THE BEST 4.3 rom yet....
[Nexus 7 General] Choriandus:
I still have battery drain in 4.3 :(
[Nexus 7 General] khaytsus:
I have factory reset my n7 four times total, each time because of lag. It always helped by only for a week or two. Since moving to 4.3 and reseting, I have had no more lag. Good stuff.
[Nexus 7 General] tcat007:
I found rooting (factory reset) and running Lagfix did most for me stopping lag. I found Greenify and Wakelock Detector does most for my battery.
[Nexus 7 General] testadeferro:
I still have this crazy mediaserver drains like allways... strange... why!? Sometimes it takes so much as screen. I don t store pics music or videos on sd card.

Can someone with a Nexus 7 test this and report the outputs. Trying to trigger Android 4.3's built in fstrim manually. Run "adb logcat -d | grep -i fstrim" before and after to see if fstrim was indeed run once more.

Guys this is kinda off topic, but do you

think google is going to make a 64GB version, and sell it like the 32GB and eliminate the 16GB version, (Like they did last year with the 8GB model)

:\ i really dont want to buy the 32GB version, and then after 1 month, there's a 64gigs v, for the same price

If you were using an ad blocking host file you will need reapply it.
[Nexus 7 General] prestige777:
I do use ad away, but the point was that ads never opened tabs automatically before, even without an ad blocker. Installing ad away again took care of the problem, though so its no big deal.

Can [MENTION=5077195]hassam_tariq2003[/MENTION] try my last kernel on 4.3 to see if WiFi works? If it doesn't, then I'll have to branch and start working on the source again.
[Nexus 7 General] prestige777:
No the popup blocking settings are enabled, its something new that google enabled, it has nothing to do with popup block settings, it does this in every browser.

WiFi lags and drops out. Any fix for it? App installation and web browsing takes too long and I'm like 5 feet from router.

Just got mine today brand new and updated to 4.3
[Nexus 7 General] veeman:
Did you do a clean install?
[Nexus 7 General] jblazea50:
It was a clean install. I unboxed it and then used fastboot to erase everything and fastboot to install the new images.

Installing Google Drive took like a minute and Chrome beta like 3 minutes. My internet speed is 20 down.

[Nexus 7 General] Dark Jedi:
I am tethering off my phone and my WiFi on my N7 is still perfect like it was back on 4.2. Maybe a compatibility issue between your router and 4.3?

I think Google got it right on 4.3. Seems the lag of 4.2.2 is gone as everything seems to load fast and even the keyboard doesn't lag on me at times like it did on the older os version. I just can't wait till we start getting custom ROMs and kernels and this thing is going to fly. Going to breath new life in to the old girl lol.

[Nexus 7 General] sjondenon:
A few questions about the new 4.3 build:

- Does it have a new kernel?

- Did Google do anything about the screen calibration (colours etc.)?

- How's the browser performance (especially Chrome) compared to 4.2.2? Chrome was laggy as hell on 4.2.2.

- How is the overall smoothness? Does it now scroll steady at 60 fps or is it still a bit choppy when scrolling slowly?

- How is the battery life?

Thanks!
[Nexus 7 General] jbaumert:
Does anyone else have apps with "Show Notifications" unchecked and still have the notification still showing up? The notification does not show initially, but comes back after a reboot.
[Nexus 7 General] khaytsus:
Anyone having problems with root needs to follow Chainfire on G+, he's been working on Root since a 4.3 leak in early July and it's still not quite right. Google changed quite a bit about how root used to work with Android apps.

I had to flash the zip twice and reboot a few times before any apps showed I was rooted at all, and folks are saying that the new daemonsu service randomly locks up and takes 100% cpu until rebooting and/or root randomly stops working and you have to reboot and possibly re-flash. I'm sure this will get sorted out eventually, but very annoying right now on rooted stock.

https://plus.google.com/+Chainfire/posts/WqS2E9kkN1L

I've also seen slow wifi, but I haven't tried it again today. It could have been a temporary thing yesterday, but hopefully it doesn't persist as like other people it was taking forever to download small things from the market.

And anyone saying their Nexus 7 is "like new" and "buttery" again, did you all do a full wipe, install the Nexus images from Google, etc? If so, yeah, that always made the N7 "buttery" again. Until the storage gets filled/fragmented again, anyway.
[Nexus 7 General] slybunda:
its running super smooth on 4.3, i can notice the rendering improvements straight away in the chrome browser, scrolling and zooming is much smoother, and seems to be better on battery too so far.
[Nexus 7 General] testadeferro:
Using this for one day and don't feel difference at all. Performance is same in benchmarks, maybe a bit snappier in scrolling. Battery life is to early to comment before first 5 cycles. But media server drain is still ruining my battery.
[Nexus 7 General] danvee:
Pretty sure there's one over in the Dev section.
[Nexus 7 General] hassam_tariq2003:
-Yes it has a new kernel.

-Not anything in specific.

-I never experienced any lag in Chrome on 4.2.2. but they have improved the stock browser.

-It is alot more smoother than 4.2.2. and still a little choppy.

-the same....
[Nexus 7 General] spinosa:
Yep. I find that if I recheck, start the app, go back to settings and uncheck the icon goes away for a while. Definitely a bug though.

---------- Post added at 09:44 AM ---------- Previous post was at 09:41 AM ----------

After flashing 4.3 (boot, system & bootloader, TWRP and supersu's beta daemonized version) I find that, in low light situations with a light background, I get very noticeable flickering. This was NOT happening in 4.2.2. I do a lot of reading on the device and flickering is quite distracting - I would have noticed...

Turning off auto dimming in settings does not cure the problem nor does changing the wifi power optimization setting.

On the positive side the 'auto brightness' app seems to be able to reduce this to manageable bearable levels. I seems the light sensor's reading jumps all over the place in low light levels and this confuses android 4.3.

Anyone else?
[Nexus 7 General] mgl888:
Anyone know how to revert to gtalk from hangout?
[Nexus 7 General] :
I flashed-- it's pretty nice so far. I was doing a marathon run with a CM10.1 combo over the last seven days (and I'm convinced my Nexus 7 could have made it until the ninth day off the charger), but this convinced me to charge up and flash. So first up is the battery test, since they're boasting some real improvements here. Here's hoping, but it looks pretty good overall (minus the initial root snafu).
[Nexus 7 General] PVL_93_RU:
It's always like that on 4.2.2, and 4.2.1, and 4.2

It's not caused by auto dimming or WiFi optimization

It's the stupid NVidia Prism function that's enabled by default and supposed to "reduce power consumption", but in fact it does not work properly, it changes the brightness accordingly to what is currently being displayed, thus causing it to jump from 10 to 50 to 20 to 45 etc.

Though I noticed that flickering is to still there on white backgrounds sometimes (like in Play Market). But it only happens on the minimal brightness. Turning it to 10-15% is enough to get rid of it. But it is an awful bug. Thank god that Google decided to put Snap S4 Pro in Nexus 7/2. Now I realize that Tegra frickin' sucks ass

Anybody else having issues with flash not working on 4.3? I have only tried boat browser and chrome beta, which both were working on 4.2.
[Nexus 7 General] mssam:
How's the bluetooth? A lot of complaints about it on 4.2.2...
[Nexus 7 General] bluecarbon:
Having a few issues. Lmt launcher's back and menu buttons won't work on 4.3, I can not get Horn to work at all, even tried using a 4.2.2 ROM in multi-boot and horn still won't work, and fullscreen will not work, so I had to use hide soft keys. Haven't had any issues so far with root. I used the toolkit to install the images in the tgz folder, then flashed twrp, from there I flashed the superuser.zip. I hope things get ironed out soon.
[Nexus 7 General] GedBlake:
Wow... finally found a kindred soul who also thinks that NVidia Prism is nothing but a damned nusicance!:).

I used to run a script at boot (automated with ScriptManager), with the line echo "0" > /sys/devices/tegradc.0/smartdimmer/enable... to disable it. But since I got Franco's updater app, I now just set it to DISABLE in that apps Custom Kernel Settings.

But I can always tell if it's failed to disable it (for whatever reason)... a subtle, but irritating flicker is ever present (particularly, as you say, on white backgrounds). TricksterMod (free on PlayStore) should also disable this tiresome irritation.

I'm surprised Google haven't attended to this problem with 4.3.

The more I read here on XDA about 4.3, (various reported problems with root, Titanium, etc), the less enthusiastic I am about upgrading:(.

Rgrds,

Ged.
[Nexus 7 General] zamuz27:
Just upgraded to 4.3 and I'm having issues with the wallpapers. When I set one it ends up looking very distorted, even though they're pretty high resolution (higher than the N7's screen) and this didn't happen in 4.2.2. Anybody else seeing this?
[Nexus 7 General] Tommy-Geenexus:
there are no root problems. it runs just a lot times better than 4.2.2

[Nexus 7 General] skippa:
Has anyone received the OTA update yet? The legit way?
[Nexus 7 General] PVL_93_RU:
Why make such a difficulty for yourself when you could just use the NVidia Tegra PRISM Toggle app from the Play Store, set it to disable and "Apply on boot" and never again think about it?
[Nexus 7 General] zamuz27:
Well for anybody having these issues, this app seems to work well: Image 2 Wallpaper

And I did find another app that does something rather strange that I've never seen any other app do: AutoResizeWallpaper. This one actually modifies the aspect ratio that Android crops to, so that it fits the image that you want to set as wallpaper. For example, this is what it looks like when trying to set a 2560x1600 image as wallpaper using the "traditional" method (long tap on home screen, select wallpaper from Gallery), and the result is a noticeably distorted background:

If you use AutoResizeWallpaper instead, the image looks good and has no distortion.

But this is what happens if you use the "traditional" method again, after using AutoResizeWallpaper:

As you can see Android now wants to crop this image to the aspect ratio of the 2560x1600 image I used before! This is kind of insane to me. No wonder I've seen so many issues with wallpapers and Android in the past, if apps can modify what aspect ratio Android uses to crop images.

Sorry if I got a bit off-topic, but this could help in case someone has the same issues I'm having.

[Nexus 7 General] getinnocuous:
Installed 4.3 stock zip with the root patch on my 32 gig WiFi Nexus 7 and things have been just lovely ever since. Got TiBu working after changing the backup path to the legacy folder and stayed up way too late last night pretty much running everything, spending a lot of time in SunVox without closing out other apps and everything was smooooooth as butter.

I guess this screen flickering is my only issue! I put on a little Netflix last night as I was going to bed, room all dim and such, and I noticed these sudden, extremely brief quick flashes interrupting my video. My initial thought was "OH GOD SUBLIMINAL MESSAGING / MY TABLET'S POSSESSED" because I couldn't really make out what the image was, but I just might have to give this app a try.

also: Read in some thread around here that USB OTG isn't working? Can anyone confirm that (I lost the cable I just bought like a week ago so I gotta go and buy me a new one)?

[Nexus 7 General] Kilek_360:
Is not an issue, i read that in 4.3 all apps in background have a persistent notification, in my opinion that is the only reason im thinking to stay in 4.1.2.

If i uncheck the "show notifications" box of any app will it work properly?

I read somewhere that may cause problems...

4.3 is very smooth, Chrome works perfect for me, I haven't had any lag yet.
[Nexus 7 General] khaytsus:
Well, no, it's not. It's caused by interference between the wifi, screen, and IO. Not sure if it's internal or external (electric noise) interference, but it has zero to do with Prism. Disable prism, go into a dark room, white background app, load some wifi data. Like news apps are where I always see it. It's not Prism.

Prism has its own problems, but not the "low wifi backlight flicker" problem.

As for root being flakey, it might be fixed.

https://plus.google.com/113517319477420052449/posts/Jkuu84odnx6

Chainfire fixed the root issue, the zip in his G+ post should work. He's concerned that this may not be the final version, but it's working in the cases he's reproduced problems.

On another note, wifi where I work has not worked since Froyo. It was broken in 2.3, 4.x, 4.1, 4.2.. But works in 4.3! Enterprise WEP (802.1x), TTLS, PAP. It worked with no fooling around, just put in the info, user info, bam, connected.

Just perfect. Recently I had so bad battery problem even with stock rom & kernel and only few apps. It was draining 1% per 1-2 minutes. Now I see it's 1% per 5 minutes, same usage (reading), lowest brightness.

No sure if placebo but it feel it smoother too (like 4.1.2 was)

And the smart bluetooth is amazing.

Great update!
