[AT&T Samsung Galaxy S II Skyrocket SGH-I727] FourGates:
If you are rooted you can install setcpu and underclock your CPU. You can have a profile to set it very low when the screen is off and this should help a lot!

But installing a custom rom would be the best option to maximize your battery. I'm using [ROM][UXKJ2]Buoyancy v1.3.0||Rogers/AT&T||[1/25/12]

I'm on 12 hours and I'm at 52% with light usage. Pm me if your interested in a newb guide to installing a custom rom!
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] checkyoulater:
About a week ago, I decided to try a little experiment. Turned data off when not in use, and monitered my battery drain. It made a huge difference. I can go well over 24 hours, and still have 40% battery.

This is on TPC v3 with his oc script. Unfortunately, I never tried this with the stock Rogers rom, but I'm pretty sure it would make a big difference.
[G Tablet Q&A, Help & Troubleshooting] noto45:
I am running Vegan 5.1 with almost no issues. I want to upgrade to a newer OS but not sure which one I should try. Any suggestions??
[G Tablet Q&A, Help & Troubleshooting] sjmoreno:
My question to you is "Why?". If you're current install on your gTab is stable and it lets you run what you want to run why do you want to "upgrade" to another ROM. If a different ROM will give you something more than what you currently have like maybe let you run a cool video game (Shadowgun) which can't run VEGAn 5.1 then that would be understandable. I was a happy user of VEGAn 5.1.1 for a good part of a year and decided to move to Mountain Laurel 3.1.0 only for the fact that games like Shadowgun will run on it.

So, if that is the case and you feel you will get more out of your gTab by moving to a different ROM then I would suggest you do a full backup via ClockworkMod of your current install so if you choose to revert back to it after you've tried some other ROMs you will be able to do so easily.

Also, it is VERY important for you to figure out what version of the bootloader your gTab is currently running. You can save yourself a lot of wasted time if you figure that out first and then plan your path to a different ROM.
[G Tablet Q&A, Help & Troubleshooting] noto45:
I have some apps that will not run on it. I am not sure if its the OS but I cant even download them from the market. I was hoping another OS would fix that. I also thought the newer versions of OS run faster? I am not sure but I am a newbie to all of this.
[G Tablet Q&A, Help & Troubleshooting] tsukaza:
Since you like Vegan 5.1 then why not try VeganTAB 7.1, it is very stable.:)

I ran it using clemsyn's 1.6 kernal and it is fast.

http://vegantab.gojimi.com/

Also the new CM7 7.2 which is also based on Gingerbread is another one I recommend.

I am currently using it. It comes with a 1.4ghz OC kernel already.

BTW to make thing runs better, change the VM stack size to 64M.
[G Tablet Q&A, Help & Troubleshooting] sjmoreno:
There could be a few reasons why an app will not run on your gTab or will not show up in the Market for you. It may be that you are trying to run apps that are for Gingerbread or Honeycomb. It may also be that your LCD density is keeping some of the apps from appearing in the Market.

As for newer OS versions running faster, I've tried about five different ROMs and VEGAn 5.1.1 is by far the fastest (you can overclock it if you want to run at 1.4 ghz or higher with custom kernels). So when I switched ROMs away from VEGAn 5.1.1 it wasn't about speed but rather better video driver support.

On more note, VEGAn Ginger and most other ROMs will take what seems like forever to boot up compared to VEGAn 5.1.1. Keep that in mind if do make the switch so you won't think your gTab is stuck during bootup when trying other ROMs.
[HTC Rezound] danutzz:
Love the speed on my 4glte (30mbps! WOW!), plus I do have unlimited data (grandfathered), so the only reason I use wifi is so that I don't over abuse the unlimited data every month, or if I want to save on battery life.

That said, wifi is extremely slow. I have 20mbps cable at home and I only get 2 through my phone, even when standing right next to the router. My laptop connects to the same network and gets 10!? Why is the wifi on these phones so slow (same issue with tbolt)?

Also if u have unlimited data how much do u use month? Are you afraid they might take it from u?
[HTC Rezound] dawynkoop:
I've noticed the same thing. I have 35/35 internet at home, but when the phone is connected to WiFi I don't get anywhere near those speeds. I actually almost get better speeds leaving the phone on 4G even though I'm lucky if I have two bars at times.

Never have been able to find out why, but since I do have unlimited data as well (grandfathered) I typically just leave the 4G on and forget about WiFi.

My typical data usage per month is two maybe three gigabytes with moderate usage, but now that I'm on 4G it might increase some since I'll probably use Google Music more often.
[HTC Rezound] AtLemacks:
I get 25mbps to my home and pull 17-22 on the phone. You may have a bad antenna. Also, speed test isn't very accurate. Your "speed" is restricted to what the server you are pulling from can provide. Also, you may have a bad/slow router. If it is dated, I suggest upgrading.

So long as you are not using exponential amounts of data, like 8-10GB, they shouldn't throttle you, and they CAN'T just take it from you.
[HTC Rezound] con247:
I don't have unlim because I just switched last week. But I have the double data 4GB plan. Really glad I have that and not 2 gig because I am using an average of 2-3x the data that I did each day on my Desire before I switched. LTE just causes you to use more lol.

I wish I had unlimited because I would watch a fair amount of netflix over 4G
[HTC Rezound] AtLemacks:
BTW, I have a Linksys E1500 Router.
[HTC Rezound] Evo4gLI:
I agree. You may have a bad antenna, because my Wifi speeds are just fine. I get 30 down and 7 or so up, so there's no problem there. Here's something I've noticed though: My wifi won't stay connected while the phone is asleep. It always goes back onto 4g for some reason. This happening to anyone else?
[HTC Rezound] voxigenboy:
The only time i get wifi is at Starbucks or the library... and both places are show as hell. No internet(or even tv) at home because i am rarely home. So that being the case, i absolutely never ever use wifi period.

As for data usage, let's just say it's enough that a few people here have labeled it "abuse".
[HTC Rezound] con247:
It is a setting. The phone is set to go back to 3G/4G after 15 minutes of sleep by default. You can change that in Wifi Settings. You may have to hit the menu button and go to the "advanced" menu to change the setting.
[HTC Rezound] Evo4gLI:
You are my hero.
[HTC Rezound] zetsumeikuro:
I use 10-20 GB a month and they don't throttle. They only throttle top 5% of 3G users and only on crowded towers and peak times.
[HTC Rezound] postmortem.:
low WiFi speed usually means your router is using overused channel (channel that many of your neighbors are using). WiFi Analyzer is nice free app that will tell you which channel to use.
[HTC Rezound] Scott:
Try changing the channel on your router.

That's about what I get too. I don't think it is the antenna, I think its the channel and or the bandwidth / modulation settings on the router.
[HTC Rezound] nev310:
I noticed when I turned my data connection of my WiFi seemed faster. My home network is maybe 15-20mbps and I usually get 12mbps in speed test. If I have data on WiFi is slower.

4g even with one or two bars is about 6-

12 mbps but I loose signal in parts of my house.
[HTC Rezound] nrfitchett4:
no problems for me, get wifi at 10-20mbps down and 5 up, and my home plan is 30/5 so that is good.
[HTC Rezound] jbh00jh:
My wi-fi works as good as the data connections, no problems with wi-fi being slow. Use wi-fi 80% of the day and it is always fast.

[HTC Rezound] drtnsnw:
Almost always on LTE now. I don't see anywhere near the speeds others get. Usually around 5megs.

This month already I have used 4 gigs of data. the most I ahve ever used in 3g was 3.6. BTW, my billing cycle is only 5 days old :):)

Gotta love netflix and Sons of Guns!!!

[HTC Rezound] AtLemacks:
You might be in an extended coverage area, and like I stated above, SpeedTest is not accurate at all and completely dependent on the server you pull from. Try changing servers and I bet you see faster speeds.
[HTC Rezound] Serinety:
a friend of mine said that verizon will throttle you above a certain data usage. So we decided to test the theory.

I setup an FTP from my home PC, and proceeded to DL , over 4g, my entire movie collection.

It was a little hard to do because the SD card (16gb one) kept getting full. I ended up with about 33GB of usage for that month. (This was using the droid charge a few months ago)

no overage fees, no throttling.

However I bet if i did that every month, i might see throttling.
[HTC Rezound] jbh00jh:
If you lived in a high use location (like NYC) you might have gotten a warning. :D
[HTC Rezound] danutzz:
I checked this "advanced" setting just for the heck of it and saw a setting for "best connection" or something similar. It seems by default this is checked off cause it says it uses more battery. Once I turned this on I doubled my wifi speed so it seems like everything is now working correctly.

Thanks everyone for the posts and ideas! Great community here when we're not flaming each other about who "might" be coming out with root...lol
[HTC Rezound] chaoscentral:
Actually, throttling on VZW is only for 3G users. Verizon currently has no plans for throttling 4G data users because there is more than ample bandwidth. This was in an internal document that leaked a while ago when they said they were going to start throttling the top 5% of users.
[HTC Rezound] koszor:
my phones wifi as compared to my fascinates wifi is actually amazingly better, 4g in my house is only about 8 Mbps where as my wifi can get upto 15, im usually on wifi as much as i can because i believe its better on power

pop the back off of your phone and make sure none of those connectors are blocked cause my first impression of the rezound was that the wifi was really really fast lol
[HTC Rezound] Imitation:
After turning off that "WiFi Auto-On" feature, I've never used Wifi. Always connected to 4G.

Total Bandwidth: 5.316 GB this month (10.28 - 11.28)

Got the Rezound on the 14th; w/ Droid X used 2GB before upgrading.

Never have gotten higher than 2.4GB on 3G before. I blew that out of the water with this phone.
[HTC Rezound] brisdaddy1207:
They only throttle data when your on a congested cell site, so if you live in the burbs or boons you can use as much as you need with no worries. If you go into the city they'll slow you down. Everyone has this thought that they'll just slow you down, doesn't work like that.
[HTC Rezound] voxigenboy:
hmm... when I had my Incredible 2(obviously, not 4g) I averaged about 20GB/month on that and it seemed to always stay around the 1Mbps range....

and of course, you can imagine I do a tad more then that on my Rezound, and yep... never experienced any throttling or extra fees... so that being the case, man.... the people that actually do get throttled must be doing like 50 - 100GB/month
[HTC Rezound] brando56894:
0.98 GB in 9 days. I don't really have the need to watch videos on a daily basis.
[HTC Rezound] Mean Bro Greene:
I use this phone and the Thunderbolt before it as my home internet connection. I've used ~50 gigabytes a month for the past 3 months and have yet to see throttling. Then again, I live in a town of about 27,000, so these towers aren't getting congested. It's nothing to pull 25mbps down here.
[HTC Rezound] AtLemacks:
I wouldn't exactly call it a "congested area", but I was in South Bend yesterday, and went to the College Football Hall of Fame for lunch. I jumped on their free wifi and tested the speed for ****s and giggles, fastest was 21 down, then I jumped back to LTE only on the same server and got 48 down. All of these free WiFi hotspots may start going the way of the landline soon! lol
[HTC Rezound] nev310:
I don't know if any body noticed but there is a best wifi performance setting under wifi. I did a speed test without it checked and got 8 megs down and one with it check and got 21 megs down without moving my phone.

[G Tablet Q&A, Help & Troubleshooting] cedrikfd:
Hey guys,

I have a Viewsonic G Tablet (running CyanogenMod 7.1) and a Sony Ericsson Xperia Play R800a (flashed with R800i UK Generic 4.0.2.A.0.42, locked bootloader, Rogers locked and not rooted).

What I am looking to do is use my G Tab as my phone when at home, like install it at my desk and answer calls and SMS from it directly. Somewhat like a bridge between my Xperia Play and my G Tab. Then, when not needed, just "disconnect" them and go my way with just the phone.

Answering SMS would be way faster with the USB keyboard I have and it would make a crazy looking home phone.

I tried searching on Google and in the forums but couldn't find anything... perhaps I missed something?

If you guys know something that can do what I'm looking...

Thanks!
[G Tablet Q&A, Help & Troubleshooting] Apodidae:
There aren't any telephony components in the gTablet. That said, you can still do voip. The Google Voice app will let you do sms. And GrooveIP works with a Google Voice number. If you use GV, then you can use your tablet as a second device. You might be able to forward your cell phone to a GV number to transfer calls (don't think you can forward sms).

Skype also works on the gTablet.
[G Tablet Q&A, Help & Troubleshooting] jbuggydroid:
Just listened to Android central's podcast and somebody mentioned getting the paid app gvoice. From what I understand it allows you to make calls via internet (wifi or cellular data) and receive them using your google voice number. dunno about being able to disconnect like the way you want but worth checking out
[G Tablet Q&A, Help & Troubleshooting] regmar:
I installed Skype, then bought a phone number ($15 / year) and bought an international calling plan ($15 / year - optional) so I could be reached on vacation. I forwarded my phone to my Skype number, and voila! any calls coming to my home number go to my tablet.
[G Tablet Q&A, Help & Troubleshooting] cedrikfd:
Hey all, thanks for your ideas

I can't use GVoice since I'm in Canada, and I'm looking for something a lot easier

I basically want my tablet to act roughly like a Bluetooth headset (communication still handled by my phone on the GSM network) but with a dialer that would allow me to key in the number I want to dial.

Worse case scenario, I can live without the SMS but I would really like the phone to work as I want

Someone mentioned the G Tab does not have telephony capabilities. Can that be installed at all since what I'm looking for is hooking it up to my actual phone by Bluetooth and therefore don't require an actual SIM in my tablet?
[G Tablet Q&A, Help & Troubleshooting] alanhzl:
there is an app called tablet talk, you can google it, which allows you to pair your tablet n phone via bluetooth to send n receive sms.

[Kindle Fire Android Development] airmaxx23:
If you don't mind sharing I'd like to know how you have it set up exactly, I usually use auto killer and it now fc's on me also.
[Kindle Fire Android Development] chairshot215:
Is very easey, Google and download V6 supercharger. Should see a guide in the first few posts that contain a download link. After downloading the zip extract and place the script in the root of the SD card (main SD card directory, not inside a folder) then do the following,

Download busybox installer from the market and then install an older version like 1.17.1. The script apparently has issues with newer versions above 1,17.1 so be carefull as by default the busybox installer app will have the latest version selected for the installation. Think its something like 1.19.

Download script manager from the market and select browse as root and then select the script you extracted to the SD card and the script will run.

Once it runs the only option I used was option 10 witch will ask you to set a value for each slot like autokiller. thre is also a few preset values listed as options 1-9. After you add a value for each slot enter 16 to exit the script. Will need to reboot the first time but after that the script can be run and values changed without needing to reboot.

The values to set depends on the apps installed. I like to customize the values so the apps I use the most often are more likly to stay in memory. The nice thing about autokiller is that you can view your processes and see what slot is controlling each app so you get an idea of what apps each slot is controlling.
[Kindle Fire Android Development] CTTKDKing:
I have version 8 running on cm7 an it makes a big difference (I use option 9) . Ran it on my old tab and on my Evo and it helps a lot with multi tasking and with interface smoothness. Haven't tried it on the stock ROM yet.

Whats your battery life like, Mine sucked using V6..:(
[Kindle Fire Android Development] chairshot215:
The slots are the same categories as used in Auto-Killer. If you don't have much experience adjusting these settings or used the app presets I would recommend probably using a v6 presets, numbers 1-9. Another option would be to temporarily install auto memory manager as in the options it shows what slots all of your installed apps fall under so you know what slots control your apps. After that its just a matter of experimenting. Would still recommend keeping the first three slots low as they are responsible for system apps your launcher and background apps like Juice Defender, wich by the way works well on the Kindle running CM7.

Will only need to reboot the first time you run the script. After this you can adjust settings on fly without rebooting.
[Kindle Fire Android Development] Hydrocharged:
And the settings will stick from reboot to reboot without having to mess with them again?
[Kindle Fire Android Development] Takenover83:
Why are you selecting option 9? I have got a quadrant score of over 4K using option 6, which is the correct setting for our tablet. You should be using one of the 512HP settings, as the Kindle Fire only has 512MB of memory (not 768MB+), which is what Option 9 is.

Use option 5, 6, or 7.

5: Unledded (Multitasking)

6: Ledded (Balanced)

7: Super UL (Aggressive)
[Kindle Fire Android Development] Hydrocharged:
Can you break down what each of those different settings mean?
[Kindle Fire Android Development] Takenover83:
Choose unleaded if you like keeping apps in memory for access later. Say Browser, FaceBook, and Gmail. Side effect, tablet will be a little more sluggish and have less free memory (for the current app). Super UL will only have a app or two in memory, before killing other apps off, so the tablet has more memory to give the current app in use (max performance, max memory for current app). Ledded is a mix of the two.
[Kindle Fire Android Development] Hydrocharged:
Since I only ever do one thing at a time on my tablet, Super UL seems like the way to go. Thanks a million!
