Poll: Wifi only N7.. Keep wifi on during sleep?

With your wifi only N7, how have you configured the "wifi on during sleep" setting?
Personally i chose never because i rely on my phone for notifications and my N7 stays at home at all times, so no need for wifi to be on all day.

I'm set to always, as I often leave things downloading while I do other things.

I'm also an always on'er. Battery life is good enough that I don't find any issues with it.

I set it to never. Phone for notifications etc. If the n7 is around just pick it up and use it.

I had tried the never rule so that it would switch off during sleep but it seemed to stay awake. But now i use automate it app to switch WiFi off when the screen goes off, with a 5 min delay, its also set to come back on when three screen is switched on again, works perfectly.

Saving battery when not in use?

So I have a Nexus 7 and an S3, the former becoming recently rather redundant as I got the new iPad (was tired of lack of optimised tablet apps). I still, however, love the form factor when reading and this I do relatively frequently, maybe 3-4 times a week.
The form factor is also useful when I just want to pop out for a bit and feel like taking it with me, whereas the static iPad I tend to keep either at home or take to university with me.
The only issue is due to me using the nexus less, i am less aware of how much charge it holds. And the standby battery is terrible compared to the iPad, which I can honestly say would last about a month if I wasn't using it.
Is there anything I can do to my tablet to maybe tone down the CPU when not in use or maybe disable internet connection when not in use, as I'm sure these two things may be affecting the battery when it shouldn't.
I don't need my tablet to constantly be up to date the second I turn it on I wouldn't mind if it took a minute or so to show me new updates / emails e.t.c.
Thanks!

Keep WiFi and sync off. I don't keep WiFi or sync on (my g'nex keeps me up to date) and my standby battery is good. Never left it sitting for a full day but over 12 hours I only lose 2-3%.

used power toggles to turn sync off, but out of curiosity where is the normal menu option for it?
cheers for that, 5% a day is absolutely fine!

They made this one hard to find. Settings > Data usage > Menu options (3 vertical dots in upper right) > Auto-sync data (put check mark). It's really a pain. I use Notification Toggle to have an option to toggle it from my notifications pull-down shade.

just turn it off if your not using it or set your tablet to sleep mode

If your device is rooted use set CPU and use profiles so you can make you processor only do like 50mhz when the device is on sleep

Using Deep Sleep Battery Saver to extend battery life

I wouldn't be using any of these battery saving apps as most cause more battery drainage than they save.
BetterBatteryStats is the only app you need, free on XDA but support the developer by buying it on Google Play it really is a great app for the small price,and will identify the main battery hogs without using hardly any itself

Battery drain with 3g on terrible

Hi guys,
Is anyone else get terrible battery life with 3g and data on even on standby? I believe the phone function drains the battery and it lasts only 2 days or so on standby. I constantly have the tab on flight mode with wifi enabled and battery is much improved to about 1 week standby. Anyone else? I am on stock 4.0.4.
Thanks

Wtf r this guy even serious? I wish i had 1 day standby, what a joke

Hi Iong. We are talking about a tablet here, not a phone. Tablets should have 1 week standby at least. The battery drain with 3g and phone on is unacceptable. I think the reason is the connection to phone signal which is constant.

Mate 1 day pr 2 day standby is a lot, given the fact you install many program and it constantly connect to tinternet to check for updates notifs etx. You dont have 1 week standby whatsover, forget it. Big tablet big baterry big screen. Ot all goes scaling together

So 'l2_hsic' and 'batt_work wake lock' are the 2 processes keeping my table awake for 5 hours in total since yesterday. Any idea of what these do?
Thanks

most likely is that one or more of your apps is causing the problem. try a reset and see if the problem goes away. if it does, install apps one by and and check which one is the problem

Use juice defender ultimate in tablet mode. I can go several days idle time and lose almost no battery.

Nexus 4 turning on by itself?

So i notice a problem, sometimes i don't know why how my phone got turned on, and it stays on without going back to sleep or anything. It literally drains my battery from a full charge to 50% in less than 4 hours. I dont know whats causing it, but initially i thought it could be the GO SMS because i allowed it to turn on whenever i got a msg, ( really like iphone that pop msgs) but i dont think its the case cause my phone to turn on.

Check your display settings. You might have set the screen time to more than xx seconds/minutes.

Are you running a custom ROM or kernel?

[Q] Use n7 as home phone

I plan on using my n7 as my home phone, i will also attach a speaker to it so that it is loud enough to be heard throughout my home.
I have a question to anyone that uses their n7 heavily throughout the day, have u run into any issues by leaving your n7 powered on for more than 6-8 hours? like i said i plan on using it as my home phone, and it will be powered on for a long period of time and, it will mostly be on stand by. screen off with wifi on and talkatone in the background awaiting any important phone calls.
any positive inputs would be appreciated

I leave my n7 on all the time with the Wi-Fi and GPS radios always on and have hardly any issues.
If l realize that I have not rebooted it in several days, I'll reboot it - though I honestly don't remember ever needing to reboot it other than when messing with the recovery, or installing a kernel.
While it's setting there with the screen off with Wi-Fi and GPS on it seems to only use 1 to maybe 2 percent of the battery per hour.

That sounds fantastic. I'm going to go though with it and use it as a Home phone

I use my nexus 7 8gb WiFi for a home phone. It's a great tablet for it. Makes for a great time killer when your waiting for a phone call. Lol
