This is quoted from a guy on google forums - https://productforums.google.com/forum/#!topic/nexus/9B1a9GvqbMs

Follow the instructions here:

Sorry but i don't speak english very well.

You have to download the 4.3 Nexus's ROM here : https://developers.google.com/android/nexus/images

and the SDK Packages here : http://developer.android.com/sdk/index.html

1) Install the google USB driver

2) Unzip the SDK and make sure you have java on your computer.

3) Unzip the Nexus's ROM into "sdk\platform-tools\" directory (look the picture)

https://lh4.googleusercontent.com/-...AAws/yGm68pKIyEU/s1600/Capture+D'écran002.jpg

4) Boot the nexus holding power vol UP and vol DOWN (fastboot mode)

5) Unlook the bootloader using cmd into the plateform-tools directory

https://lh5.googleusercontent.com/-...AAw0/80Ia52VuO6s/s1600/Capture+D'écran003.jpg

6) when done (about 1 or 2 seconds) run flash-all.bat

7) wait ! (about 90 seconds)

===> DONE !

when all is ok, power off the nexus, reboot into fastboot mode ( holding power vol UP and vol DOWN ) and lock the bootloader using "fastbook oem lock" command.

I'm very sorry for my english !!

i made the downgrade and all is ok for me.

Uninstalled Skype and no more battery drain

I installed Skype on my Nexus 7 Android 4.3 and ever since I installed the app, my Nexus 7 would lose about 5%-10% per hour even when in sleep airplane mode.

I just uninstalled Skype and no more battery drain! Microsoft sabotaging Androids???
[Nexus 7 (2013) General] PeatCoal:
Thanks, just to confirm, this will wipe all my data right? As I said, I'd only do something like that as a last resort, because it's inconvenient for me. If anyone has any other suggestions I'd love to hear them.
[Nexus 7 (2013) General] dakunclear:
Yes it will wipe your tablet completely so if there is no other alternative use this method
[Nexus 7 (2013) General] namhuy:
There is camera bug in KitKat, just disable camera service, you will be fine

[Nexus 7 (2013) General] klobkelosh:
Why bother, when you can just uninstall Skype? I use my camera, only Skype causes a problem...
[Nexus 7 (2013) General] dakunclear:
cause it doesn't work for everyone and if you use your tablet as a camera you should be slapped but that's just my opinion lol
[Nexus 7 (2013) General] PeatCoal:
Like I said, I've uninstalled Skype (a week ago) and I still have the problem.
[Nexus 7 (2013) General] klobkelosh:
Gotcha. Guess I'm lucky it's only been Skype so far for me.

Oh, and fwiw, I use my tablet, camera and all, as a field data recorder. It works very well for that purpose, and combined with the built in waas enabled gps+glonass and a custom data logger, makes a great all in one device. Surely I don't deserve a slap for that ;)
[Nexus 7 (2013) General] dakunclear:
Nope just people that use them at concerts or traveling cameras lol but your use is very useful
[Nexus 7 (2013) General] anasmunir:
Hello.

I am also facing the same problem on my Nexus 7 v2.

Should I uninstall the Skype app completely, or greenifying it will solve the issue??

My device is completely stock and un-rooted.

Thanks in advance.
[Nexus 7 (2013) General] klobkelosh:
Greenify non-root will only hold it at bay for so long. I'd uninstall it completely.
[Nexus 7 (2013) General] GSLEON3:
Really, any app that accesses the camera can cause this state. Hangouts (video) can cause this issue, as well as Tango & even some 3rd party camera apps.

Lol... The title needs to be changed OP. It is definitely NOT Skype spying on everyone. It is a bug, that's all & Google will patch it eventually.
[Nexus 7 (2013) General] klobkelosh:
But there's still a problem that Skype can launch the camera service without being logged in at all. I may be wrong but haven't heard of other apps causing camera related battery drain without any interaction.
[Nexus 7 (2013) General] anasmunir:
Thanks for the reply.

I have uninstalled Skype completely and now the battery nosedive is gone.

But the problem is, my Nexus 7 v2 is still consuming a lot of battery for an unknown reason.

I have attached some screenshots of my battery stats.. Can you please tell me if they are normal??

I have heard the Nexus 7 v2 can last for approx a week in standby, and gives 5 to 6 hours of screen on time.

My device is brand new, and I have bought it few days ago.
[Nexus 7 (2013) General] anasmunir:
Screenshots..
[Nexus 7 (2013) General] anasmunir:
Screenshot...
[Nexus 7 (2013) General] klobkelosh:
I dunno, looks normal after the nosedive.
[Nexus 7 (2013) General] PeatCoal:
Sorry, I only just saw this post. Is there any way of doing this (disabling the camera service) on an unrooted device?

Yesterday I Greenified a ton of apps, turned my wifi to 2.4Ghz only (suggested somewhere else), SKype has been uninstalled for days, and today I'm still getting ridiculous Android OS battery drain (90% wakelock and the battery only lasting like 24 hours with a few minutes screen on time)

I noticed yesterday that BetterBatteryStats can show me kernel wakelocks, and the culprits seem to be "suspend_backoff" and "qcom_rx_wakelock".

I've tried Googling these two and didn't find any viable suggestions. I think my battery drain is wifi related because it didn't seem to be a problem on my last holiday when I had no wifi signal most of the time.

Can anyone help? Sorry for spamming this thread so much.

Edit: just as an update in case anyone was having the same problem, I decided to go all out and back up my apps with Helium, unlock my bootloader and install the official CM11 nightly. Battery life is back to normal. Haven't tried installing Skype yet.
[Nexus 7 (2013) General] klobkelosh:
Hopefully, this puts an end to this thread:

Skype updated with 'aggressive battery savings,' disables group chat push notifications

Battery life bug tied to camera access in KitKat also fixed

http://www.androidcentral.com/skype...avings-disables-group-chat-push-notifications

So, yes, this WAS a skype problem.
[Nexus 7 (2013) General] anasmunir:
Yes :D

Its time to reinstall Skype. :p

*Fingers crossed*
[Nexus 7 (2013) General] klobkelosh:
let us know how the new version works!
[Nexus 7 (2013) General] anasmunir:
I haven't installed the new version yet.

I am planning to root my tab, and then I'll install all my apps from the scratch..

Has any one else tested the new version??

Is it still draining battery, or not??

Please post your feedback. Thanks.
[Nexus 7 (2013) General] zoltan.fekete:
Tested latest Skype version and battery life now seem unaffected. Installed this morning, up to now I don't see anything strange.
[Nexus 7 (2013) General] C5Longhorn:
Thanks for posting. I'm going to keep an eye on this thread. I'm still not ready to put Skype back on after how massive the battery drain was with the previous version.
[Nexus 7 (2013) General] anasmunir:
Okay I can confirm it too..

No more massive battery nosedive after installing the new version of Skype.

It's been 10 hours and my battery is performing normally..
[Nexus 7 (2013) General] C5Longhorn:
Good to know. I will probably reinstall now to test also.

Heres my batt usage with the latest skype installed:

Looks OK to me. Anyone else?
[Nexus 7 (2013) General] LinearEquation:
Good to hear. You can try Greenify to stop it from waking and if you do root use DroidWall to prevent internet/data connection until you say.
[Nexus 7 (2013) General] namhuy:
Properly because of KitKat camera bug, try to restart your n7, use Skype and don't use camera.

[Nexus 7 (2013) General] Federic0:
it was skype for me too. uninstalled, wiped cache, works fine since 2 weeks now.
[Nexus 7 (2013) General] r9800pro:
Same happened to me and when I unstalled Skype, it went back to normal.
[Nexus 7 (2013) General] gr8twhite:
Dunno guys, this is with the latest Skype on my nexus 7 2013:

Its no 6 or 7 day standby, but pretty good IMHO.

I get 6-8 hrswith constant use surfing the net, looking at YouTube videos, using BT with Torque, etc.

Pretty much the only game I play on it is angry birds (time waster when waiting for something) but that seems to chew right through battery life. I only play it maybe 20 mins at a time or so anyways.

No movies or video.

I'm on 4.4.2, unlocked and rooted....
[Nexus 7 (2013) General] mbamberg:
Several days of data, Skype now removed!

All,

My buddy was having all kinds of battery discharge issue and being the great engineer he is, did the following series of tests:

"Thanks to all the pointers you sent me. The results of my experiment are in and pretty conclusive and all finger points at Skype. Here are the experiment results:

-- Skype installed but flushed from Davlik cache; Wifi on while sleeping; battery loss per night: 33-40%

-- Skype installed – flushed from Davlik cache, tablet rebooted after Skype session; Wifi on while sleeping; battery loss per night: 25-35%

-- Skype installed – flushed from Davlik cache, tablet rebooted after Skype session; Wifi off while sleeping; battery loss per night: 18-20%

-- Skype uninstalled; Wifi off while sleeping; battery loss per night: none – charge state did not change overnight.

This is a real pity as I like the way Skype works on the tablet and I wanted to use it for that purpose. Let us hope Microsoft gets it fixed."

He's running a stock set up, no unlock, no root, latest OTA update.

I have the same tablet, but mine is unlocked, rooted, and I'm running CleanROM 2.5 with Flar's ElementalX kernal.

I have no problems with my battery, with or without Skype.

Why wouldn't you just toggle it when needed?
[G2 General] noname1x:
Good HSDPA+ enough for any task, LTE enhances comfort, but a quick discharge of the battery - it is a very high price for it.
[G2 General] Hid3rs:
Unfortunately I only have 500MB/month. With the speed OP mentioned, I could use it all in ~35 seconds. :D It's great, but kind of sad to be honest.

I have only 250MB), but G2 is really fast!
[G2 General] ndnesh:
WOW!
[G2 General] force70:
Ummm...113mbps isnt that fast really guys.

I would average close ton that here in toronto on pretty much any of my devices and have seen close to 140 mbps on occassion.

I have a 6gb plan and go over every month lol.250 or 500 mb plans? I dont know how you guys deal with that....

I dont have battery drain issues either using LTE.

[G2 General] Steamer86:
Constant 4G doesn't actually use much battery. When switches start taking place, it can make quite an impact.

Not just the international model... All models should as it is a "feature" of the snapdragon 800 chipset :)
[G2 General] phoenix_rizzen:
7-12 Mbps on average using HSPA+ on Rogers.

40-70 Mbps using LTE (unofficial, still in testing in our town) on Rogers. Wife and coworkers get 70 Mbps on Bell/Telus.

Rogers did a contest last year when they turned on their 2600 MHz LTE. The vast majority of the entrants were getting over 90 Mbps.

u joking where are u ?
[G2 General] Billy Madison:
No! A h*ll not!! You kiddin' aren't you? there are antennas, there are amplifiers don't you know? the modem is only latest part in chain of the radio.

Read this topic http://xdaforums.com/showthread.php?t=2444131 if you've not heard of QFE1100

The antennas in G2 is best thats why it is faster than Galaxy S4 or even Note 3

that is fine it can be but if network will cap your speeds u can have even 30 times fast antenas radios whatever and it will be for nothing ..

I dont understand I have LTE but speeds are like on 3G up to 15Mbps .. Just fake .. yeah right they shows it is LTE and keep people happy but reality is somewhere else.. that is standard procedure here in crafty UK .. just lies, tells bull**** to people ..
[G2 General] ceyo14:
Dude, the speed depends on so many factors... but it really depends on the area... the only place i tested it it was 5m for H+ and only 6m for LTE on a HTC One X.

Just the same in H+ regardless of signal i can have varying speed with the same signal in different places...

[Xperia Z1 General] dante2086:
Galaxy S5 just announced. And I have to say, the Z2 kicks it's ass. Heck, the Z1 might even have a thing or two to say to it. Never thought I'd see the day. But some features Samsung omitted are odd. Especially when u consider 3GB RAM and 4K recording can be gotten on the note 3.
[Xperia Z1 General] jonmorris:
No QHD screen and 'only' a 16MP camera, albeit with faster AF fix times and improved HDR. Even Samsung is running out of things to wow people with.

The fingerprint detection isn't meant to be that hot either, and waterproofing? Yeah, that's unique. :)

But Sony has been a bit lucky as it could have been a lot more, leaving the Z2 looking like a poor show.
[Xperia Z1 General] shem2409:
The only 2 things that got me excited about Galaxy S5 are the ultra power saving mode, which is putting an Amoled screen to a good use and the 10hr LTE web browsing. I won't believe it until I test that in person though. That sound's nuts, taking into account that I usually get about 3hrs on screen time with Z1 and when testing Z1 Compact I managed to get around 5hrs.
[Xperia Z1 General] Moze666:
S5 is like:

Samsung S5 is old people phone :D Private mode, kids mode for your grandchildren :D Camera sticking out OLD, but not for huge Nokia camera :D + backside looks like old case, that was attracting to the eyes :D and a HEART MONITOR? Why? Old people will really like that, phone + heart monitor, 2 in 1 :D
[Xperia Z1 General] krabappel2548:
Samsung S5 looks like **** :eek:

Specwise it's about the same as Z2 probably. But Z2 looks 100 times better :D
[Xperia Z1 General] omnius1:
Why should this even be a surprise? The Galaxy series have never been great phones for people in the techie crowd. They're more for the average John Q Public.

Could anyone post some pictures so let the mocking begin ;)
[Xperia Z1 General] Option58:
Umm, op... Could you please change title to "Galaxy S5 announced. Z1 kicks it's ass" xD . Cause that is what's true already. No need for Z2 in comparison with disappointing S5!!
[Xperia Z1 General] kantk20111:
Honestly even the Z1 looks better than the S5. Considering the amount of hype Samsung generated with their 'overhauled' UI and new metal frame, the end product is complete crap. Just look at it...it looks like a cheap chinese ripoff. Somehow I think it looks even worse than the S4. Even the 'all new' UI is the same crap with new icons. No innovation either, they blatantly ripped off the fingerprint scanner and waterproofing from Apple and Sony. Samsung make the most uninspired, overpriced crap I have ever come across. Touchwiz is sh*t and their design is sh*t. I really wish Sony or HTC had the marketing budget of Samsung so that their phones can become popular and represent Android instead of Samsung. Why anyone would buy this over the LG G2, new HTC One or Z2 is beyond me.
[Xperia Z1 General] _-..zKiLLA..-_:
This is spot on ^ lol
[Xperia Z1 General] Gitaroo:
lol, Samsung do to pump out clones of their own before chinese knock off flood the market with galaxy clones. Yeah, really wish Sony got the same kind of backing from the Japanese government like Samsung does for mega marketing campaign. And they also need to get their stuffs out quick, heard Z2 won't be available in NA for at least 2 months after other regions, by then all competitors would have sold millions already.
[Xperia Z1 General] funky0308:
Awesome... I had one of those in 1998 ;)

Really, I though guys are overreacting but it really looks plastic and cheap...

But, as I said many times before, I never liked Samsung, it always look kinda cheap to me...

But there's many great friends (mine) who are loving it - so I'm happy because they got a new toy (this time it's a real toy :D.)

BTW, if it's powered by KitKat, how come Samsung are allowed to use that kind of battery icon?

I thought Google was clear about KitKat icon philosophy...hmm....
[Xperia Z1 General] mujj:
I cannot wait for the Z2. Haven't been this excited about a phone since I got my first android phone (desire) about 4 years ago. The specs seem perfect, but the only thing I'm wary of is the size of the phone. Will it be too bulky?

You guys are forgetting the rumor about a premium version of the S5, i doubt Samsung will remain with that piece of crap(still high end flagship hardware) as their flagship for a whole year

They must be planning to release that premium metal version we've all heard about
[Xperia Z1 General] Rekoil:
And why do they keep insisting on trying to make phones that have removable batteries waterproof? Best case scenario users become paranoid and worry about the casing staying attached (and it's gonna wear eventually), worst case scenario a whole bunch of phones ruined due to "user manufacturer error".
[Xperia Z1 General] Shan89:
Who cares what else they release , this is the main version and the version reviews are gonna compare it with so this is a 2014 flagship? from sammy.
[Xperia Z1 General] kantk20111:
If the S4 is their flagship, we can assume it will sell for around $800. How much are they going to charge for the so-called 'premium' line? $1000+? You'd have to be a fool to buy that with phones like the Z2 and HTC One already having the premium status for much less.
[Xperia Z1 General] negrobembon:
They'd be crazy if they sold the S5(crappy plastic version) at 800 just to sell a premium for 1000, we're not talking about apple here

they probably will sell the plastic version as a cheap high end device at a low price probably 400+ and a premium metal edition at 600+

Or maybe they'll make a new premium line called Galaxy F, if we go by the rumors
[Xperia Z1 General] techstudio:
Wish the Z2 would come to Verizon....
[Xperia Z1 General] kantk20111:
That's not going to happen. There's no way they'll sell this for $400. The S5 will be at least $600 at launch. It doesn't matter if it's crappy plastic, their marketing budget is so big that that doesn't matter. All that matters is that it's the new 'Galaxy phone' and that's enough to make people buy it.
[Xperia Z1 General] negrobembon:
Yeah, now that i think of it, 400 is too far fetched but yeah 600 seems about right and 800 for the supposed premium line

Be aware that you will lose a lot of the Samsung gimmicks and bloatware and some people find it hard to be without them once they switch from a Galaxy(except me, i ran away from my S4 as fast as i could)

If you like those features then consider the S5, otherwise get the Z2 and feel the PREMIUM
[Xperia Z1 General] Nidhal AKA the king:
loooooooooool :D

i need aid kit box :D
[Xperia Z1 General] se1000:
I know what I'm getting into. Call me crazy but I like the capacitive buttons on the bottom and wish Sony would add those. That and Qi charging would make the Z line perfect for me. Either way, passing on the S5 and I'll be spending my money with Sony when the Z2 is released.
[Xperia Z1 General] drsoran2:
The Xperia V, Xperia ZR, Galaxy S4 Active and also the Xperia active and go (I believe) are waterproof and have removable batteries.

I like this fact a lot and thus you can just easily change the battery yourself after a few years and keep using the phone.

With the Z1 I can't do that myself because of the non-removable back and the waterproofness. It costs extra money and time.

So I like that feature, on the other hand, I'm already paranoid enough about the waterproofness of my Z1 and check if the flaps are okay often.

No wonder as a former XZ owner who suffered from a lifted back cover but luckily I got my money back and bought the Z1.
