Nexus 7 battery dies fast - Nexus 7 General

Hi, I got a nexus 7 for Christmas and the battery was really good lasted all day, but I had to return it for an exchange because there was circle marks on the screen,
my new nexus 7's battery dies really fast, i left it on charge all night and it fully charges so I don't think its a battery issue maybe a software issue?
I don't know if this makes a difference but my first nexus had 4.2.1 pre installed but my new nexus I had to update it myself.
Is there a way to fix this or should I return my nexus to PC world?
Thanks in advance!

The main difference I found when switched from 4.1 to 4.2 is that Wifi didn't go on standby when the device wasn't awake. So go into wifi settings and change it so it's only connected to Wifi when the device is in use or charging.

I changed the Wi-Fi settings now, I'll let you know if it helps.
Thanks

It stays on' I went into Wi-Fi settings and pressed the 3 dots on top right > advanced > keep Wi-Fi on during sleep and select never and it should turn off when your nexus 7 is sleeping.

What? Could you restate that so that we (or at least I) can understand? It sounds like you're saying 2 different things.

Hello, I'm in the UK and I'm facing a problem similar to yours.
I got my device at the beginning of December, and used to get ~8-9 hours of screen time. Now, I'm barely getting 6, and you can add screen lifting and back light bleeding issues to that as well.
I'm going to preform a factory reset in a few days, if that doesn't work, I'm considering getting it to customer care/replaced.
PS, I'm stock 4.2.1 and my Wi-Fi doesn't turn off when it's in sleep mode. :-\
Sent from my Nexus 7

mine last 4.5 days with light web browsing. mostly just mx video player. 17% idle. you need to see whats keeps your device awake and not letting it goto sleep properly. i'm on latest smoothrom. i manually turn off wifi when i am not gonna use it for awhile. when i 1st got my nexus 7 i had a similar issue with mediaserver process using 80% of battery and killing the device within 9 hours. i couldnt pin point the culprit but hasn't happened again.

Its a shame really I honestly thought Google had made a good and reliable tablet I had to return my other nexus back again today because I dropped it and the battery wouldn't charge so they replaced so I'll see how the battery does

Battery Problem
I had the same problem / My Nexus got switched off and even drained even when the usage is less / Switched to Zerolemon battery and no problem after that.

Silly question but have you checked for installed app's that's keeping your n7 awake and in turn draining the battery?

My battery life has been holding up well from a secondhand Unit I bought a few weeks ago. I'm getting about 7-9 hours of life on average use with a little gaming.

I still have that problem on CM 11 M2

Yeah...saying my battery life sucks isn't going to help anyone help you. How about some details? Screen shots? Do you have Gsam....its a great tool to find battery issues.
Without some digging....your battery troubles aren't gonna go away.

Please Fill Out Your Nexus 7 Complaints Here

I've taken the time to make this thread to hear about any complaints people may have about the Nexus 7. Keep in mind, this thread is NOT for PHYSICAL defects or imperfections. I'm talking about complaints about the performance, any lag at all, crashes or freezes, horrible battery life, performance with major 3D games, or any bugs you may find, post them here ! :good: Complain all you want about it, let's discuss it. Is the Nexus 7 what you were expecting ? Is it BETTER than you expected ? Is it good for the price ? Are other tablets better in any way ? Say it !
Is this really necessary?
I thought it would be interesting to know. Thank you for replying !

Check it out in the pictures and let me know what you think; I don't have any frame of reference for the quality of these and I don't want to have to be out of a device for a long period of time for an issue that doesn't really bother me.

You definitely have a rogue app killing your battery. My mytouch has better screen on time then that. It also goes against what everyone else with the device have been experiencing.

Screen on time?

Quick battery life question for you guys. When your battery is almost totally depleted, what does your screen on time look like? 3 hours? 4 hours? I have a GS3 and for me it's somewhere between 2.5 and 3 hours. I assume the One would be a bit better due to the LCD screen instead of the amoled.

I've been getting about 2.5 hours of screen on time. Generally amoled screens use less power than LCD.
Sent from my HTCONE using xda app-developers app
Really? My gs3 does 4-5 hours. And yes, I use the phone.
Sent from my SAMSUNG-SGH-I747 using Tapatalk 2
I'm pretty sure amoled uses less power also, particularly with darker colors.
My screen on time has varied depending on usage. Mostly I have been playing games, the 3d ones tend to take a lot more juice. Certain less intensive games and regular browsing/texting/videos seem to draw a lot less. I'd range my screen on time from 3-5 hours depending on this.
So I'm having a hard time finding the screen on time. I go into the batter setting, check usage and scroll down below the apps to system apps and cannot find it. Am I missing something? I apologize for the ignorance but I'm having a hard time.

yea judging from what I've been seeing on the forums you should be able to get around 4 hrs screen on time. I'll be kinda mad if i get less than that with moderate usage considering I get 2-2.5 hrs screen on with my GS2 at the moment.
Im getting my phone today so I'll report back after a few days of use
5 hours a day is normal. 5:40 is peak.

Battery life 1 week
Hi,
I own my note 3 now 3 weeks and use it primarily as an organizer (acalendar+) with phone-capabilities. I dont use big internet-bandwith. So I usually use the GSM-network and avoid UMTS. I rooted my device to be able to reduce processorspeed via juicedefender as soon as the screen is switched off, As I found it unacceptable to live with a short screen-timeout, I installed "screen off and lock" to switch off the screen manually as soon as I am done.
I am syncing my Lotus-Notes calendar at work with google and sync once an hour (controlled by juice-defender) via gsm.
I usually use the calendar twice an hour (as I enter most of the appointmernts in Lotus Notes I do only reading)
Bluetooth is switched off, GPS is switched off
with this I enhanced my battery lifetime from 2.5 days to 7 days
Last week my note 3 survived 1 week without charging. This week I am at 68% after almost 3 days (see attached screenshot)
