I find myself either on wifi or 3g 99% of the time and I rarely even turn on the 4g radio. Does anyone actually use 4G more than wifi and 3G? I don't like that I have to turn it on and off, if I could leave it on all of the time and not destroy my battery it would be great.
[Epic 4G General] Geekybiker:
Sure. When I'm sitting down out of the house and know I'm going to be doing some serious browsing.
[Epic 4G General] Sh0wNuF:
I would definitely use it if I lived in an area that had 4g but it would be a toggle thing like wifi if I did use it
[Epic 4G General] fatsack1:
Works great in Dallas.....
[Epic 4G General] boomerbubba:
Is the premise that the 4G radio draws more battery power than 3G a solid assumption? Subjectively, I find that 3G is a battery hog. But I have not tested rigorously to compare 3G and 4G.

I get better battery with 4G

I think there are some drawbacks to using 4G. Pictures messages don't come in and sometimes the market is a little bit slow to do anything. But I have had 4G on for the last week, and can make it through the day with juice to spare (I get to work at 7:30am and plug it in at 10PM.)

It seems like the 4G sleep mode does what it is supposed to. I am running Baked Snack 1.3.

I'm with you... really, I find myself finding excuses to use 4g just because I should since I'm paying the 10 dollar fee... mostly i just use it when i have very large downloads or if i'm plugged in and receiving a good signal ill kick it on while doing some browsing... but really i haven't found much real use for it consistently... in part because its such a battery hog (which i don't understand why it hogs so much more battery than 3g but w/e) and in part because wimax isn't Officially released in nyc yet... so my 4g coverage is spotty and minimal at best.
[Epic 4G General] BrianFX:
I disable 3G 95% of the time for the massive battery savings. I just use 4G and wifi when the need for data comes up. 4G turns on faster than re-enabling 3G via the Quick Settings app.
[Epic 4G General] itsmebryan:
So you have found 4G is less of a battery hog then 3G? I won't have 4G till Dec so I don't know. I found on AT&T 3G was a hog and I would turn it off it I wasn't on the net.
[Epic 4G General] crazaytalent:
how does one cut off 3g, unless you talking about airplane mode, which is difficult to do when u get a lot of call and texts, ... i need my device fully functioning as far as phone services go...

but if there is a way to disable 3g (data only and still have operational phone services, id love to know how to do that.
[Epic 4G General] DevilDogVIKING:
I use 4g all the time. That is my main source of internet. I don't have a wifi connection so 4g is my lifeline.
[Epic 4G General] itsmebryan:
That's another feature that I miss from WMs modded roms. I could turn off 3G and just run on AT&T edge network. You may need a modded rom or root you phone to turn off 3G on this phone.
[Epic 4G General] SkulloCrasher:
Well, the Switchpro widget has a data connection toggle that cuts off 3g, but I'm unsure of how to do it manually through menus.
[Epic 4G General] shook187:
3g what is 3g? I for one never had a 3g phone and I don't plan on using it. Why would I use 3g when I have 4g and pay extra for it? 4g coverage in Boston and outside of Boston is very good, so I'm not sure why I would ever use 3g.
[Epic 4G General] itsmebryan:
3G is a older and slower connection than 4G. We all don't have 4G yet. Some have said that 4G uses more battery then 3G. Alot are trying to get the most out of their battery and try different things.
[Epic 4G General] Xhyperion:
I use it to download psx roms , movies, kernels, epic roms etc. Its useful.
[Epic 4G General] coolqf:
I live in DC, and I have always leave 4G in auto on. I barely notice the diffeence between 4G and my wifi. Now, that's pretty cool. 4G is WAY faster than 3G in my area.

4G use to be a big drain, but with the latest update I find my phone always lasting the whole day. My Palm Pre would always struggle by 8PM, and it would get less use than my EPIC 4G.
[Epic 4G General] p-niiice:
I use it all the time in Atlanta, and even get a good signal in my house.
[Epic 4G General] Unknown Zone:
well I am giving spirnt one yr for 4g in my area which I am pretty sure it will not happen, so my next upgrade I will be going back down to 3g. 3g phones by then should have either a 4.0 or 4.3 screen which I want anyway and a 1ghz would be nice to 8) .
[Epic 4G General] NeonMonster:
Sprint almost has all of Sacramento covered in 4G.

Tried it yesterday and I got 3x faster than my home DSL connection. :\\\

I checked Sensorly and there is now 4G less than 10 blocks away from my house! :D

I use 4g when not home only cause its not in my area. 4g even at the slowest has a faster dl speed than my home connection (300kb) and the fastest I had 4g was me downloading a 66mb file in 1min. I love it

I use it at work because our firewall blocks certain sites.
[Epic 4G General] churro7:
i would if i had it here

and when im in 4g areas i use it only

otherwise 3g and wifi
[Epic 4G General] Mutiny32:
Actually, yeah, I do use it. I live right on the edge of 4G coverage; sometimes I'll get it at my desk in my house, sometime I won't, but it switches over to WiFi anyway so I don't mind. Almost everywhere else I go in my area has 4G and it is great.

As for 3G, it is by far a MUCH larger drain on battery life than 4G or WiFi is and I assume it's because of the clusterf*ck of a baseband firmware Samsung has for the CDMA chipset. Really, if I lived in an area with 3G only, I would take the phone back.
[Epic 4G General] pissinguoff247:
I have a 4g antenna on the roof of my office building. I use pandora and stream stuff all day long, and I do it over the 4g to save my it department the grief of me hogging bandwidth. I am a little annoyed about the pix messaging failing over wimax... incomlete implementation = fail. I would love to tell you about battery life but I leave it on the charger during the day... sorry.

I get 9.5mb(950kb) download on 4G here in Atlanta... **** yeah I use it.
[Epic 4G General] aero1:
I am with you. In my tests having 4G on saves battery life.

What I am seeing is 4G tends to slow in poor RF conditions while 3G tends to respond to poor RF by pulling more power.

I wonder at any claim that 4G uses more power, are people running tests? As I have three epics I am able to try out a lot of comparisons, and what I see is 4G saves battery over 3G. Variables such as RF conditions,a and type of data you are pulling are of course present but I wonder at any per se claim that 4G draws more power. I don;t see that at all.
[Epic 4G General] Mutiny32:
That's because of the advantages SOFDMA modulation combined with other technologies in the 802.16-2005 spec has over CDMA. Much higher spectral efficiency. Expect 802.16m to bring even more advantages once ratified within a month's time; which is actually as little as a base station firmware update away from us because it is backward-compatible.
[Epic 4G General] ravizzle:
I use 4g a lot and its not horrible on battery. Only time 4g caused a lot of batt drain was when iwent outside 4g area and it was constantly searching for 4g which makes sense. So just make sure u turn it off when u travel outside 4g area.

[Epic 4G General] Erica8123:
I rarely use my 4G. I use it during large downloads and that's about it. I find it won't stay connected anywhere besides home anyways. Besides my battery drains so fast I can't waste precious juice on 4G when I'm not home or in the car lol.
[Epic 4G General] durhamite:
thanks for all of the responses everybody. From the response it looks like 4G doesn't really murder the battery and for everyone in a 4G market it is great for them. I am in a wifi hotspot most of the time (at home and at work) but I think I will turn 4G on outside of wifi to see how it goes.
[Epic 4G General] bomix:
Testing 4G in my downtown area i wasn't impressed by the speeds,, I was waiting for the 10x faster then DSL. It didn't drain as much battery as I thought, but then again i was testing it for only 45 mins.. it drained like 3% during that time.
[Epic 4G General] Geekybiker:
I don't know about 10x faster. Ive been getting 7mbs though.
[Epic 4G General] BrianFX:
I found that DATA is a battery hog. By disabling 3G, I can get 2 full days from a single charge. Slightly annoying that my weather widget can't update, but it's a very small price to pay for wonderful battery life.

Quick Settings from the app market. Disabling 3G still allows calls & txts to come thru. I have gmail setup to auto-forward to <my number>@messaging.sprintpcs.com as SMS, so I get all my emails pushed to me as 160 character-limited previews. Gets the job done nicely.
[Epic 4G General] Geekybiker:
Why not just use something like tasker to setup an auto sync every hour or so and leave the 3g radio off the rest of the time? I would imagine that would get you the best of both worlds...
[Epic 4G General] ravizzle:
Use juice defender, it disables 3g when screen is off and catches email and updates data on set intervals that u choose. I have it fetch every 30 minutes. Also u can set exceptions like for if u use panddora it won't shut off 3g when screen is off etc...

Sent from my Epic 4G
[Epic 4G General] boomerbubba:
The advantage of BrianFX's SMS-forwarding solution over your suggestion, or Geekybiker's, is that there is no significant delay in getting notified about each email. Your solutions would impose a latency of 30-60 minutes.

For many users, that is unacceptable. I would not want to cripple the inherent advantage of a smartphone -- getting immediate communications from work, family, etc. -- just to preserve my battery. That sort of defeats much of the purpose of carrying such a device.

Of course, the two methods are not mutually exclusive.
[Epic 4G General] Sesquipedalian:
There's 4G in Nashville, but I can't use it most of the time cause it's so spotty, and the phone doesn't go between 3G and 4G very gracefully.
[Epic 4G General] BrianFX:
Precisely.

Also, there's no benefit for me to having 3G on when the screen is on (via JuiceD/tasker), b/c my most active use is when I'm on the subway. Wifi/4G are both quickly accessible from the pull-down menu for when data is needed other times.
[Epic 4G General] thomasskull666:
4G works fine in downtown St. Louis, but out farther west there is no service so basically I never use 4G unless I'm going to a baseball game or something. When I did use it for about an hour, I didn't see ridiculously significant gains either and battery drain was a bit more than 3G so for now, 4G is staying off.
[Epic 4G General] chino0131:
I primarily use 4G when I'm using data, or if I ever find that I'm not near Wifi and I need to make a call while surfing the internet at the same time.
[Epic 4G General] Phen0m:
Like Chino above, I only use 4G(if there is no wifi) when i need to surf while in-call
[Epic 4G General] APOLAUF:
Absolutely use it. Was getting over 8Mbit in Cincinnati, and here in Nashville it's easy to get 3-5. Works GREAT when you don't have WiFi around, and is especially nice when you want simultaneous voice and data. Makes things so much snappier than over Ev-DO, and lower latencies really make a difference.
[Epic 4G General] boomerbubba:
I do use 4G most of the time around my city. But I find that Sprint's coverage map is overly optimistic.

At home, for example, the map shows that I am supposed to have a 4G indoors, but I really don't and my exterior walls are thin materials. There are pockets, even some on freeways, where 4G drops out completely. On the plus side, I have decent performance (3Mbs down) inside my concrete office building downtown.

So I disable 4G at home (WiFi is better there anyway) and enable 4G elsewhere. I do think that when the 4G coverage is stable, it uses less battery than 3G. When driving outside the urban coverage, of course, I turn 4G off.

Hopefully some of the infill coverage holes will get filled in over time. I suspect that Clearwire is pressed for capital to get everyone wired, just recently announcing coverage for NY, LA and SF markets. Because the technology is more susceptible to line-of-sight shadows and building attenuation, getting the nth pockets covered is probably very expensive.

I have excellent 4g coverage in Seattle but have a 30 megabit connection at home so I use wifi here. I really haven't been home much with my epic but now that I'm getting a local job my biggest concern is battery life. Since I drive for a living I suppose being plugged in is pretty easy anyway so I may start leaving 4g on

[Epic 4G General] mousiluck:
I've actually started using 4g a lot more than I did when I first got the phone. I'm not too sure how much of a battery drain 4g is compared to 3g, but I did notice that my battery life ended up being a little better for some odd reason.

I'm actually usng my phone as a hotspot for two other people I work with. When I'm running the hotspot on 3g the speeds are pretty slow, the phone itself tends to get pretty warm, and the battery drains quite fast. (Probably because of the constant data traffic). But once I turn 4g on not only is the speed faster, the phone stays pretty cool, and i'd get somewhere around an extra hour or so of battery life compared to having it off.

I could just be imagining it all, but wouldn't it make sense to use data as little as possible. So using 4g over 3g should be a better right? say you were downloading a 400mb file and you can get it done in 15 about mins of data traffic with 4g on compared to about 30 mins of data traffic with 3g...I'm probably being a noob and not making any sense to you guys at all, so I'll just stop.

[Edit] I'm in Boise and no matter where I went I almost always have a 4g connection. [Edit]

I use 4g ALOT man its like lighting in a bottle!! Crushes my battery tho...
[Epic 4G General] compuw22c:
In Chicago...

Here in Chicago, 4g is pletiful. The issue is, even in the car driving around, there are coverage holes, lots of them. Granted, I live right by O'Hare (not quite the city proper) but all of chicagoland is covered. If you look at sensorly charts you can see there really isn't THAT great a range from each tower. The result is that while watching Youtube in the car, I'll be humming along just fine then boom, handoff from 3g to 4g, and loss of video (also happens with skyfire streaming, or any other constant data requiring task)

For this reason, I turn it on when I need it ONLY. It is SUCH as hassle jammin' to some rockin' tunes on youtube to just have it drop out entirely.

If they could handle the hand-off between interfaces (and ip addresses) seemlessly, or at least teach the apps to try and reconnect via the other available interface, it would be MUCH MUCH more useful.

Cmon sprint/google, give us 3g-4g handoff. I KNOW it can be done! (maybe hand out the same ip to the same phone on BOTH interfaces, using 3g as fallback path??)
[G1 General] Dr.Gonz0:
Okay, so I had this G1 for about a month now, works fine, rooting was a blast, but I wanted to get rid of the cracked digitizer glass. So the part comes in the mail... I read and followed the take-apart tutorials to the letter, install it, put it back together, and what's this???

The screen is dark with no display, I slide out the keyboard and I get a display but no back-lighting. I wait for the thing to get to the home screen and I am not getting any touch-screen action. Any ideas? It is safe to assume the digitizer may be dead but what's the deal with the darkness?

Prior to installing the screen I had the back-light issues and I thought "maybe one of the flex cables are loose" but now I am dead in the water. Any info anyone would have about this would be helpful :)

Thanks
[G1 General] lbcoder2:
That sounds like the right thought. Clearly, something isn't connected properly.
[G1 General] CrusaderNN:
As i see, there are three variants (from good to bad):

1.) You`ve connected some cable badly, or, for example, you`ve didn`t put down the black blocking panel on some of connectors where it is. As for me, i`ve additionally put some scotch upon any connector i was attaching - it works.

2.) Some cable went bad due to inaccurate handling. When i was doing the same thing (replacing G1 digitizer) - it was stated in manual, tha flex cables, especialy black ones, connecting mainboard with LCD&touch block - can be easily torn. You should examine then carefully - electrical tester would be a nice idea.

3.) You`ve spoiled some chip on the board with static electricity on your fingers. It is really rare - but really bad variant.
[G1 General] Dr.Gonz0:
Hehe turns out that the flex cable was already fried before working on it, thanks to a great friend I received a new flex cable and was incredibly surgical putting all those cables back in, but I did it. Back up and running @ 100% muahahaha!

So how do I cook for this device?

[Galaxy S I9000 Q&A, Help & Troubleshooting] [Ramad]:
This is a normal error for Eclair if you flash a non multi-csc firmware because the requested folder is not there, what you need to be careful about next is to backup the efs folder before doing any other flash. You need a copy of that folder, you can read many threads about missing IMEI number or changed local and sales codes, and these errors cannot be corrected unless you have a copy of the efs folder. When you have a copy of that folder then you may flash as much you like to JPM using 803.pit with no re-partition and the tar file as PDA.

I figured I'd make a thread about some of the weirdest stuff you've had happen to your SGS. Only a few minutes ago I had a little incident which made me wonder, what kind of weird stuff do other people deal with?

I'll start.

A few seconds ago I tried playing Angry Birds. After it loaded I clicked play and the screen didn't change. Instead random dark lines started to appear horizontally across the screen. At first there was one and then slowly many, many more started to appear. None of the capacitive buttons worked, nor did the home button. Eventually it got really bad and I lost all hope so I held the power button and it reset. All seems fine now.

The time before that I was flipping through some menus fast and I started getting mass FC's. I decided to restart the phone. Upon booting up ALL info that I downloaded or came from Bell was gone. The Remote PVR app and everything, was gone. The factory reset button in the settings menu didn't even work. After doing a reset via the 3BC everything worked again.

Now, what kind of crap have you had to deal with?
[Galaxy S I9000 General] AllGamer:
hmm... how about a double weird even of the same magnitude? ;)

So, here i was doing stuff happily with the SGS on me, suddenly i hear the phone have restarted on its own i was like OMG!!!!! :eek: WTF!!!! :confused:

it was just once, and i was doing stuff, so i disregarded it and continued with my life.

then shortly after (30min ~ hour) the same thing happened :eek: so i was left pondering :confused: and started to investigate, only to find out that the belt letter case that i use have an exact opening to activate the buttons (never paid attention to it before) and when i sit down the rugged parts of the Jeans will press exactly right into the spot where the On/Off button is located :p:D:rolleyes: mystery solved

solution move the belt case a little bit more to the front to avoid the hard edge of the jeans plies

But!!!.... that's not over... the SAGA continues!!!....

not long after at around the same time (a day or 2 later) the phone did it again, it rebooted on its own IN FRONT OF MY EYES (i was texting in the toilet), so i said it aloud WTF!!! :eek: this definitely was not a Jeans/Belt combo issue, it was not the SMS / XDA App program causing it.

so i started to investigate, i installed a new app recently that i was testing (superpower), it worked really good for the first roughly 12~24 hrs i was using, made some options changes

then it worked even better, however the reboot was caused by the app that i installed it.

removed the app and now the phone is back to normal ever since.

How's that for excitement?
[Galaxy S I9000 General] davanw:
Every now and then, when using it to play music in the car, it will turn itself off. Not a graceful shutdown though. It will be playing one minute, then BAM, it's turned off.

Holding down the power button for 5 seconds won't turn it back on. Even multiple tries.

But holding the power button down for a solid 10-12 seconds will turn it back on. Then after it boots up, everything seems normal again....
[Galaxy S I9000 General] black heart:
well, I was showing the phone to a friend, he has an iPhone 4, he saw the Angry Bird icon, he said, ok let's compare the game between ur SGS and my iPhone4

when I pressed the home key it went back to home, then suddenly screen started getting brighter, more and more, I wasn't able to see anything after few seconds, and I was so shocked casue I read some topics about Super Amoled going brighter and then dying for ever :D I immediately restarted it using the power key, and never played angrey birds again :D this was before a month, my screen is still fine
