nice but try it with pure 3g ?
Very nice indeed but our phone uses the old 3g radio instead of rev0 so our battery will doe quicker which id why wifi is a huge difference.

recall! lol
In other words, you are saying the battery doesn't die quickly if you don't use it as a phone, and don't turn it on?
You can still make phone calls and send/receive text when 3g is off.
Doing this will save battery life noticeably.I was turning it off, before the last update.
Battery life was horrible then. Installed a data/3g off and on widget to do this easy.
After the last update, battery life was awesome and I did not have to do this anymore.But I still have the widget, in case I get into a situation that I cannot charge the phone and I will use this method to conserve power
I never tried the wifi thingy though
This is mixed use of 3g and wifi. Beat that...

Been about 2 hours since unplugged and been on 3G, played maybe 5 minutes of Angry Birds, 2 emails, 2 2 minute phone calls, few texts and browsing the android market for about 10 minutes. I'm now at 84%
Compared to the rest of you guys out there, what would you call this? Eh, so-so, decent, great, outstanding? So far anyway.
Keep in mind my RADIO and PRL have not been changed from factory since the phone has been switched over to Boost Mobile and I don't wanna lose settings since I had to pay to do so originally.

Check your Display on time, divide that by 2, add number of hours off a charger. That's how many percent of battery you should have used since unplugging (with average use between, calls, web browsing, texts, game playing etc.)
In other words, using display/cpu (with autobrightness and apps which don't consume ridiculous amount of cpu time, like 3d games) consumes about 0.5% per minute. The standby usage with 3g on will consume <1% per hour.
Anything larger than those figures, and you have a problem.
I got it. Does the Display on reset itself once a charger has been plugged in? I originally took my phone off charge around 1:10 this afternoon, plugged it in for a very brief moment (2 minutes) to put a .apk on my SDcard. I noticed my "time since off charger" reset, so does the same apply for the Display?
So it does. I'll do a full charge over night and report back.
does your 4g connection work? or you get a sprint web site?
Ok, so I'm on 2.3.4 and have the extended 2000 mah battery, but my battery drain was still pretty high. In 4 hours with barely some usage at all (maybe like 10 minutes), it drained 20% of my battery. I recall that like 40% went to "phone standby" (or "cell standby"? I'm on the dutch language so I'm not really sure).
I was connected to the internet but usually with G (GPRS, right?) connection.
I also don't use live wallpapers, or even any widgets (except the extended controls widget).
I think IM+ was running but I can't imagine it draining so much battery.
I am getting around 56 hours with auto sync on all the time and wifi on all the time during the day.. Lots of other apps like gmail, IM+, Nitrodesk are also live all the time..
I am on 2.3.5

Click to expand...
Click to collapse
2.3.5 is much much better for battery.
Of course IM+ is bad for battery if its running the whole time, it constantly pings chat services to check for replys/new messages. Ive found messaging apps like IM+ and whatsapp to be the cancer of the battery life world. So I dont use them anymore, I just use sms...
I hope 2.3.5 will indeed improve my battery life that much.

Hello.
I am having problems with the battery because drains a lot (5% per hour without wifi, 3G, screen off, etc). I looked for this problem and I found that other people resolve it installing francokernel (http://forum.xda-developers.com/showthread.php?p=36553244). The problem was that the tablet uses the 3G even if no SIM card of 3G off.
But, I have installed the francokernel and the problem keeps and I don't know why The francokernel reduce the problem of 3G but my battery keep draining a lot. Can you help me ? I attach images from betterbatterystats. The test is with wifi off, 3g off and only facebook, twitter and whatsapp installed. The model is Nexus 7 3G
Thank you.

uninstall facebook
It's draining because there is something not allowing it to go to deep sleep. Install cpuspy or similar that will tell you what the CPU is doing.
EDIT: I know there are photos but only a couple are showing up for me.

It's definitely doesn't appear to be Facebook or a lack of deep sleep. Despite not seeing the infamous Google services, you may want to verify your location settings as that can override you turning off wi-fi and mobile network.

I have tested again with CPUSpy (wifi off, 3g off, only I have used 5 min, ...). Now, I see the wakelock PowerManagerService is on 33 min. At any rate, 90% of time the tablet is in deep sleep mode and drains aproximately 6% per hour. I don't know why happen this ... Is it possible that in the deep sleep mode the frequency would be high ?
I attach images of betterbatterystats and CPUSpy. Sorry, I can't upload picture o links (but in the first message I can do it). I put the links below with a "-" behind "http".
Thanks

Try restarting your N7. Every time i have this problem I restart my tablet and the battery draining goes away for about a week

Here is another
My phone has been in my pocket all day not being used until just now when I made this post
I should also mention it is fully stock
looks pretty standard for stock to me. 5 hours for 23% of the battery? That means about 20 hours a cycle? seems very standard for stock.
If you want more then you gotta go custom ROMS and Kernels.
If your rooted use SET CPU to make phone clock speed 322-400 mhz when the screen is turned of.
But why is it awake so much?
Search for "AndroidOS Bug" and you'll get the answer.

This bug really makes it hard to enjoy the note 3 as a whole. I was plagued by this pretty badly until recently I sort of found a workaround.
Some time ago I found out, that in offline mode the bug is not present. I came across it, when i was in our datacenter where the cell signal is a nightmare. I turned on offline mode and switched WiFi back on (thankfully we have a WiFi active there) and the battery drain was very low with active WiFi and bluetooth (headset connected) over a period of several hours.
I did still encounter the Android OS bug afterwards, but then once after my phone was fully charged, I put it into offline mode for some time (30 secs or one minute) and then switched back to normal and that day I had exceptional battery life (whole day = ~12h with some time checking, messaging and checking mail, with ~70% battery left) which i assume must be the actual battery life that the phone is capable of without bugs.
So long story short:
possible workaround for the Android OS bug: put phone in offline mode for ~1 minute, then back into normal mode
I would love to read if somebody tried this and gave some feedback.
Hello,
I've experienced a sudden change in battery performance.
What used to take around 50% of battery now takes around 85%.
It happened recently, around the same time I started working at a new workplace. The reception is horrible there, maybe that's the issue. However during the weekends, it is around the same.
I was on 4.4.2 stock when it happened and since then I've flashed it again once. I've also tried a couple of different radios (and enabled LTE) and I've always had franco kernel.
Brightness was always on Auto (which I shall turn off to experiment battery life) and wifi is selected to be off when the phone is off.
I have still a few more experiments to do, but I'm considering using warranty services. What do you guys think? It's clearly not as bad as some of the other battery issues I've seen on this forum, but it's quite the change for me. I bought this phone in July 2013.
Here is an example battery usage graph. Charging finished around 1 AM and left it unplugged over night. In the morning (~7 hours) the percentage was at 75%. (5% / hr) Throughout the day, I have used it for text messaging only and by 6 pm, it's at around 13%.
Thanks for taking the time to read my long post.

You can check what drains battery with BetterBatteryStats. Google it and you'll find.
Thanks for replying.
I have tried that before an OS reset although I couldn't make much out of it. One main thing I noticed was a certain kernel wakelock which, after I googled, was responsible for LTE connectivity. Although this makes sense, I had good battery life even with the LTE chip being used (& auto brightness / wifi always on) prior to this battery incident. By good battery life, I mean 50-60% used by the end of the day
