[Q] Nitro as WiFi Only phone

I am looking to buy the Nitro HD for WiFi only use and maybe occasional prepaid use. I will flash to some deodexed ROM or maybe CM9 so I am not so concerned about software issues in the stock ROM.
What I am more concerned about is - how are the cameras for Skype/Google Video etc?
Any way to turn off all radios except WiFi by default everytime the phone starts up?
Thanks.

^^bump^^

I'll chime in here, I use mine as a wifi only device. As far as Skype/google video goes, video calls are great. I don't have a Sim card in mine and the mobile settings are greyed out which I'm assuming the cellular is off.
I'm currently running the latest cm9 nightlies and the device keeps getting better and better.
Battery life is definitely better than gingerbread. Battery life is within reason for a device this powerful while on wifi. The only battery drain I've found is being out of range of a wifi area. It seems the device goes on over drive looking for wifi and within an hour, majority of your battery is dead. This might be a CM9 issue, I'm not sure on that. Just remember to turn off your wifi when out and about.

Thanks for the response. I got myself a used one for $200 today off Craigslist. Will put leaked ICS ROM on it
Looks much sweeter than my iPhone 4S!!

UP！UP!
The super screen is eye candy. Using wifi it will last for 5-7 hours, while using 3g only for 2-3 hours.
For these two reasons, i often use it only as WIFI.
Will somebody introduce a super airplane mode without shutdown of WIFI？

Get dx battery saver, put it into sleep mode, then activate wifi.

You don't need any special app. Just enable airplane mode, then enable wifi.

oh,no, it is a two-click thing with a wifi interruption.
We want a one-click button.

If there is /system/etc/settings.xml, modify it about what is airplane mode （this is, remove “wifi” in the lines of "airplane-mode" ）.

Can rooting help your battery life?

I just rooted my phone and installed CM10a couple days ago. I love jelly bean and having my phone debloated.
My question is.... are there any roms or settings on the roms that can help me get get better battery life? The battery life on my gs3 is good but not great... I selected the powersave feature on the CPU governor, turned down my brightness, turned off gps and bluetooth. I have been thinking about installing juice defender but I have had it previously and got tired of turning it off when I streamed pandora.
I am a pretty heavy user... about 1-3 hours of screen time per charge. I have seen some pretty rediculous stats out there and would like to be able to achieve a full 24 hours. :fingers-crossed:
I had my gs2 rooted and it seemed to get better battery life than the gs3 (rooted vs rooted). There was no comparison when it came to stock vs. stock.
Any tips or suggestions would be greatly appreciated! Thanks!

Could you please elaborate how I should go about switching to that setup from kernal version 3.0.42 and the nightly CM10?
I have also had problems figuring out how to properly backup with nandroid or titanium. I can never get the backups to load
I am ready to try pretty much anything to try and get some premium battery life and performance.
I really appreciate your help and input. THANKS! :good:

Basically ya download the up to date versions of the aokp ROM and the KT kernel for aosp jb. Then ya open to recovery and first go to backup/restore and make your nandroid. You can decide whether or not you want it on internal SD or external. Once that's done ya wipe your system & caches like ya did for cm10. Then flash the ROM. After the ROM then flash gapps & fix permissions and reboot. Let the ROM settle and then boot to recovery, clear cache again and flash kernel then reboot. My instructions are a broad guideline though. I'd make sure to fully read both the aokp & kernel OP'S to get a warm and fuzzy on what your doing

seems like you are new at this so let me add a new thing, the S3 has amazing battery currently 9 hours up time and 1.5h screen on time and still 50% left and that is very light usage. Usually I listen to music play games watch movies and after 12 hours i still have about 10% left.
For starters cycle the battery a few time. Charge 100% and let it die 0% not charging in between, take out the battery and put it back in. Let it charge to 100% and and do this a another 2 times during a week. This will will use all the cells in the battery and should give you a boost. I have herd following above but charging while off may help, but cant confirm.
The next thing to do is remove bloatware or app you will never use, some of these apps will just load up in memory and use up your battery. Most apps can be disabled in Settings > Application Manager > All. Things like Allshare Play can be disabled, some apps like video hub may have gotten an update that needs to be removed before it can be disabled, this is the same as freezing in Titanium Backup. BE CAREFUL WHAT YOU DISABLE BECAUSE THERE MAYBE NEGATIVE EFFECTS.
This is what I have done and my battery has been amazing and never use power saving mode, actually i took it a step further and downloaded system tuner and disabled non essential apps like Vplayer from even booting at start-up.
Flashing different kernals and ROM can greatly improve battery life but you loose OTA and forced to wipe which i got tried of doing so i stick with stock. Waiting for CM10 to go stable then i will switch. The S3 stock is still snappy and never lags and for me battery life is very good.

thank you both very much. I just installed the AOKP rom and I will try the power cycles next time my battery dies. One question on the AOKP... I cannot figure out how to change or add lockscreen icons. and yes I have looked at the lockscreen option on ROM control. I can post screenshots if you dont believe me lol

We believe you because those lock screen options haven't been implimented in the ROM yet. If its a must have for you I'm pretty sure ktoonzes aosp jellybean kernel will work with CM10.

Lol well that explains a lot. Its not a must have but it would be nice. Hopefully they implement it soon.

One other question. My network constantly switches from 4g to HSPA to 3g. When my phone was stock it would stay on 4g (lte) 99.9 %.. is this normal? I would prefer it to stay on 4g. I also think it might hurt battery life since its constantly switching even though lte is a battery hog.

What rom are you on? I'd love mine to switch to 3g the majority of the time, LTE is such a hog, there's no way that switching it down is going to use more battery than staying on LTE full-time.

Bump.
Nobody has this issue?

A couple of issues?

- Has anybody been experiencing 3G/HSPA+ signal issues whilst on CM10-M2 or the CM10 10/14 nightly?
I completely lost my signal until I had a friend call my phone. And then it came back, but it was very slow. (The indicator was grey) This seems to happen often.
- Also, do profiles work?
I have a School profile (default lockscreen with a pattern) and a Home profile (insecure lockscreen) It seems like switching in between these does nothing since I have to still unlock the device with a pattern when I use the Home profile.
- Home button issues?
This just might be my phone, but my homebutton has not been waking my device sometimes. I have to push it extra hard for it to register.

Grey bars means you aren't connected to Google Services, I haven't had any issues with signal.
The home button is a known issue. Mine does most of the time but sometimes it takes two presses.

It could just possibly be a bad connection within the hallways (cell signal has been known to falter in there.) But even using my phone outside seems to yield a weak signal.
Okay, I thought that my home button was broken, thanks for clearing that up!
Using capacitive buttons would be some much more durable..

So, after much hassle (I managed to brick my phone) I finally managed to fix my data speeds.
Switched back to stock TW ICS.
Data speed aren't 12mbps, but at least fast enough for me to actually use my data.
Which is strange, but heck, I can finally use my phone again.
Just have to wait for the OTA Jellybean update then...

FrostyJB was the first ROM that I ever installed on my GSIII.
And I hated it....
That experience just wasn't as fast as I would like and the battery life was terrible.
I'm open to suggestions for other TW-based JB ROMS though if anyone has any.
Edit:
Even stock ICS TW doesn't suit me. Battery life is terrible (Not used at all today, screen's been on for 30 minutes = 79% battery.) and the OS itself feels groggy and slowed.
CM10 feels like the only ROM that I could really use.

For your home button, have you disabled svoice? Double press home and if svoice opens go into settings and uncheck double press home to open.
For profiles, not too sure as I've never really used them, but have you looked into apps like Tasker?
How long ago did you try the jb roms? Both Frosty and XquiziT have come a long way and according to almost everyone are great daily drivers.
For data speeds, have you tried all the different modems? My thread is now stickied in Development. Check post 3 for some build.prop tweaks that may help as well.
As for battery life, it sounds like you're just not using the correct settings if that's your goal. Turn off any features when you're not using them. Especially auto sync. If you have a poor signal this can decimate your battery. (Which may be the main cause anyway, to which id have to say to try the different modems.) I generally get great battery. Often 3-4 hours screen on and can go 20-30 hours on a charge.
Hope some of this helps.

**Edit: I got ninja-posted **
I agree on stock firmware being sluggish. It's just terrible. I personally chose to get away from TouchWiz altoghether. I don't hate the way it looks, I just like AOSP more. I've been using CM10 for over two months now.
Well, as it's been said, the home button issue has been around for a while now. Don't press it hard, just press a few times.
I don't use profiles myself. I get the feeling that the profile settings just don't encompass security settings. I would expect that to be for ringtones/volumes etc. But maybe Tasker can do this for you (PIN or slide, depending on location)? Tasker is very cool, and even more powerful. Even if it can't do this for you, it's still worth every penny (imo).
As far as your data connection, if data stops working, try cycling it off and on. It should re-establish the connection. Have you tried different modems?

I have S-Voice disabled, yes. Plus, the whole issue of the home button doesn't really bother me anymore. Simply reaching my hand up to push the powerbutton is easier now that I have switched cases.
I tried FrostyJB at the end of September.
The build.prop tweaks seem too far out of my league, but thank you so much for the modem idea!
I can remember installing the UVLI8 once upon a time and getting insane results. Will definitely give it a shot. The Jellybean modems work on JB 4.1.2 right?
My battery usage has always been the bare minimum. Literally no toggles are on (GPS, WiFi, Sync, etc) and that's my status. I've been noticing that "Cell Standby" has been the primary culprit for battery drain.

[Q] Best Jelly bean Rom For battery Life

I'm wondering what ROM people have found to be best for battery life? I'm hoping to find something close to the stock Jelly Bean. I currently get about 6-8 hours on a charge and really need my phone to last me at least 12 hours. I'm not doing anything major just some email and texts maybe a short phone call.
Any advice would be appreciated.

You should be getting closer to 13 hrs
The stock rom is fine
Its your settings causing this
Keep wifi gps off #1
Brightness down
Turn sync off in settings
Manually push for your data
Use power saving mode
Set screen timeout to 15 or 30 seconds
Iff rooted govern the cpu down some
With rom tool box app
Not to many others have bad battery life
Good luck

My answer: switch to aosp. Though make sure you're not syncing unneeded crap, and brightness also affects battery life.

Are you connected to a 4G LTE network alot? I am running GOODNESS JB and I can usually get about 2 days worth if I'm not on 4G. If I am constantly connected to 4G I maybe able to get 6 hours of battery life.

My Gps was already off, I will try some of the other things you suggested, I don't see sync in the settings. I will also turn of the wifi when I'm not using it.

Its been awhile since I looked but the festure to turn sync on and off through account /settings is now crammed deep into ics and jb somewhere
It used to be right under settings accounts and sync when USING GB
Its all trial and error
Adjust adjust adjust , main thing is keep off or down on BRIGHTNESS AND GPS AND WIFI AND SYNC

My note 2 seems to get get slower at 20% battery. At 5% the changes are obvious. Scene dimming etc. Are their settings the I am just missing? I look through that Blocking, and the Power Saving modes. None of them seem to be on.
Was wondering if a am missing something in the menus. It seems to happen on stock kernal, and the Saberkernal I am running right now. I also running Novella Rom.

I noticed that even with power saving mode disabled in the menu settings its still toggled on in my drop down menu. You can set the parameters of behavior whilst in power saving mode through the menu.

I was just wondering the same thing. I got the Zero Lemon 9300mah battery and it lasts super long. So when my phone reaches 20% I'm not sure if it slows down or not. But when it reaches 5% the screen dims and it runs slower. How can I disable this. There must be some way to stop the program that is doing this?
This is a problem because 0-5% last a very long time on this battery to try to kill the battery to zero.
Any ideas?

I'm of the belief that in order to disable the built in conservation mode...you would need to flash an AOSP build to get away from TW framework altogether. .
I can confirm no such mode exists on AOSP....g
