IntegerIsNumber: Both Nexus and S3 has the same applications, settings and configurations. One without cellular but both on wifi all the time..


And the Nexus 7 has a significantly larger battery capacity... compare oranges with oranges next time, ok?

Yes I know sir, but one has much larger screen as well. Anyway, my point is if I disable data connection when I'm connected to wifi. I get about the same battery life as the Nexus 7 on S3.

I tested this a few days back and even Data connection (as long it is on) is not being used it is still sucking the battery. No idea why.

You know, if I follow the road rules, my SV6 does the same speed as a Maserati... You're not comparing equivalent hardware, so any observation you make is irrelevant.

Yes, leaving data services connected will drain the battery more than disabling them. that's simple math. Although, you will find that having the data connection enabled will not significantly impact battery life - it's applications using that connection (incurring radio transmissions, which incurs current draw, which consumes battery capacity) that impact battery life. When you disable background data, all you're doing is telling the OS to not allow apps to communicate over your data connection while the phone is sleeping. The data connection will still actually be there. edit: I would assume that leaving the data connection open is not going to be a significant drain - unless there's some form of frequent keepalive required, but experience tells me that's not the case - it's more likely that it's just an operating state. JohnR?

To conclude, if you want to improve battery life - find the apps using background data, and remove them, or disable their background syncing. don't disable background data, which to me, is not using your smartphone for its intended purpose.

edit: look, to be honest, if you have the ability to charge your phone every night when you're sleeping, then seriously, who cares if you have 80%, 50%, or 20% remaining at the end of the day?

Agree with most of your other comments, but this one - no.

If I have to head off to the hospital, or I'm going out for dinner or some other social event till late, I don't want to find myself away from town needing to make phone calls etc with my battery close to being flat.

To have 50% battery mid evening, is a big safety net for me.

Leaving data connection on using roughly 25-40% more, even on stand by it uses much more than the nexus 7. With my average usage, it wouldn't last me pass 8hours. So having a phone that I can't use is far worst than having a phone that has data connection turned off and last me more than 16hours.

I don't mind charging my phone every night when I go to bed but the problem is I have to keep charging it every 6 hours. I did manually disable background data for some apps but the drain still there. Like I said previously, it is either the modem DLIB or the Kernel is the one to blame. Let's hope the next release of Jelly Bean has better modem and power efficient kernel.

Yep this is what I'm trying to proof that having more battery even the data connection is off is a good thing. At least you can still make/receive phone calls and send/receive texts. Way more useful than having a dead phone anyway. lol

kiwitrc: Hint: The S3 has a replaceable battery.

True but that is costing $60 or something. 

Hint; You'll need external battery charger too.



Anyway:

Dick Smith is having Garnet Red S3 on sale

I
t looks quite nice. Too bad we are a little late for the colour S3. My blue is still doing alright.

Johnk:
networkn: johnk: I'd take a backup and do a factory reset. Load no apps, and see what your baseline usage is like. What is your cell coverage like?


I might just try that, will try airplane mode tomorrow for a few hours at a time, should see if its cell coverage then?

Cell coverage for me is pretty good, always seem to be on full bars of XT, running stock ICS from Telecom, unrooted still ( I know, I cant believe I havnt rooted yet myself). Live in Henderson  at work in Takapuna at the moment, so pretty main areas for coverage I would assume.




Just did a factory reset and tested it again...NO BETTER. So next test is to change to a fresh battery and make sure it's not the battery life getting sucky.

Will report back tonight.

Lastly...if this fails to produce results...I'm going back to ICS.


Why don't you try my suggestions?

1. Deactivate Data mode (power > deactivate)
2. Settings > wifi > Advanced > Stay connected only when plugged in.
3. Maps > setting > disable location sharing, disable report from this device, disable Automatic check-in
4. Don't leave Facebook, Skype sync on. 
5. Never leave SKYPE on running (It's a blood sucker app).


You should now see your battery last longer if not by twice.

This is worth doing if before considering to move back to ICS. Or flash LF2 modem and that should fixed some Data connection drain. (My assumptions and from my own experiments).



Because...it aint that that is causing the issue. The only thing that changed is the ROM, from ICS to Polish JB and the battery started sucking a Kumera. Before JB my battery was fine will all the normal stuff running.

So, nope...

Do you have Viber installed? or Skype running?

Install Gsam battery monitor free from Play store and then use app sucker view to check out the offended app and services. I had that before and it was Viber that sucking my battery dried in 4hours.

Now something else is using GPSD daemon which I'm trying to locate the issue.

That's a good deal if you want the security of walking into a shop and buying one and having a local place to take it back to for warranty purposes.
