Does roaming use the battery more????????
I think the phone searching for towers and switching between home and roam uses the most battery. I really think its gonna be about the same.

ok thanks, i was wondering because my battery seems to go down quickly when im roaming at school i have 2 bars
Cell standby uses a lot of battery compared to screen (48% standby, 38% screen)... and my time without signal is 5%
When I'm at home, I usually get between -90dBm and -110dBm on 3G.
Is this pretty low? Would it being this low cause my phone to chew through batteries like candy?
It has to be pretty low since incomming calls usually go to voicemail and outgoing takes 2-3 tried to get it to connect.
Hmm..
Thanks
Time without signal is good. Its only 5%. If the majority of the tome your phone is off than yes cell standby will be the higher percent. If you think something is draining your battery then download spare parts from the market and it will tell you what is using up your battery and if your phone is sleeping g properly

How many bars of service do you get at your house? If you're not getting a very strong signal and you are rooted then give the app Roam Control a shot. It will change your service towers from Sprint's to Verizon's. Also follow Muscleheads suggestion of downloading Spare Parts and checking your wake lock usage.
It varies but usually 2 or less...
Sprint sent me an airave but now they won't activate it since it's "incompatible" with the epic 4g... So I have to send it back to upgrade to an airave 2 (airvana)
give the app Roam Control a shot. It will change your service towers from Sprint's to Verizon's.

It works great and roaming is included in your Epic's unlimited plan, but don't use it unnecessarily and be aware that it provides only 1X data.
I finally got all my lines ported over to Verizon and am experiencing 5x faster data speeds coming from Sprint.
Of course I am new to ICS and had a quick question. When you into settings, Wireless & Networks, Mobile network and then Network Mode, does having LTE/CDMA on make it so the LTE radio is constantly searching for LTE towers, consequently draining the battery more than having just CDMA on? Appreciate anyones help!
Yes, if you're area doesn't support it, then is is not worth it and you're wasting battery

When you have that option on yes both radios are on and LTE is searching for a signal. When you turn it off it powers off the LTE radio and runs on CDMA only saving battery

I haven't even used 4g after coming from Sprint last week. 1.7mbs on 3g is good enough for me. .
I would be more interested to know if 4g sleeps while the phone is off.

It does not. It will stay connected at all times unless your phone cannot get a 4G signal, pretty obvious though.
I just switched too ...this me at work

I figured that was the case but just wanted to confirm with you guys. Have any of you tried with and without both radios on? Battery drain difference?
If both radios are on and you HAVE 4G coverage the battery drain will be noticeable compared to 3G but nothing crazy. If you have both radios on and no 4G coverage your phones battery will drain much faster
Also, some custom roms like AOKP has an option when your screen is off it'll shut the 4G radio (or 4G/3G) data off and when you turn your screen on it'll reconnect

That was one good thing with the GS2 on Sprint, when you weren't using your data the device would put 4G to sleep until it was called on again.
The problem with actually shutting off 4G data when you turn the screen off, what if the device is in the middle of downloading something? Will it just cut it off or finish the active connection and then shut down once complete?

I leave LTE enabled all the time, and most of the time I'm in a non-4G area. The battery drain between having 4G and not having 4G is negligible, and I never switch it. The only thing I do is put the phone in airplane mode at night.
holy **** balls! I have 4G almost anywhere i go! The same place that I got .39 down with Sprint's 3G, I got 26mb down on 4G through Verizon. Didnt even know that was possible. At my home, I get 17 down! Love this phone!

Hahaha I felt the same way. I came from sprint to Verizon 2 weeks again and I love it. 4g everywhere I go. I haven't even seen the 3g icon on my phone. Lol.

Question for you guys that jumped ship from Sprint. If you left due to the contract change, did you have the etf fees show up on your final bill even though you called and they confirmed they waived them? They told me I would have to call back when they showed up on my bill to have them credited yet I still do not see the fees.

No, I did not have them show up on my account. I did call the day after I ported to make sure they were waiving the ETF. My bill date has ended and I still have a $0 balance.
I think most of the more common custom ROMs (Gummy and AOKP, I know for example) have optional pull-down toggles. 3G is plenty fast for 99% of my phone's use, but it's nice being able to toggle LTE on and off with a single button when I do want it.
For what it's worth, you will notice a greater drain using LTE, but like I've said before the screen is really what kills the battery on this phone.
I had a large ETF on my final Sprint bill. Called and they are supposed to send refund check. Probably hoping people just pay it to leave. Data speed was so slow on Sprint. Not sure why anyone would stay.

I just did the porting yesterday so we'll see. They did say that they'd show up and I'd have to call to get them removed. It bothers me that I paid them what I did for ****ty service. And it only makes them look even dumber after seeing what Verizon's network does.
They also shouldn't be allowed to get away with having such ****ty service, or if they do, they hvae to charge less. Premium data my ass!
I switched over on the 16th. They said I would have to call back in and they would credit my account and end up with a $0 balance.
I leave my wifi on so I can pick up wifi at my work or home to save on data. What is happening with the LTE/cdma radios when wifi is on?
My girlfriend and I have the exact same Epic Touch purchased at the same time from Amazon. Since we began our contract, When we travel to the Eastern suburbs her phone switches to roaming (data) until we travel West back towards Sacramento. Mine has no issues whatsoever.
I have checked the service maps on Sprint.com and they indicate strong 3G service for voice and data in the area that her phone switches to roaming.
Anyone have any similar experiences?
assuming that both phones have updated prl's, its possible that one phone may have roaming guard on while the other doesn't. Sounds like the roaming phone may be hitting a dead zone and staying on stronger roaming signal.
Make sure u turn roaming off. I used to just be switched to roaming in places I could get 4g but then after I disable roaming I got good sprint signal

Does turning off roaming affect just data, Voice or both?
Just and observation on LTE and battery life if you are in an area that has been refarmed to get LTE but may not have the strongest signal for it yet.
I get constant LTE signal wherever I go in Baltimore. Download speeds are great. But the signal isn't super strong yet. So my phone does a lot of pinging the towers to stay connected. That is the yellow signal in my battery graph. This causes a decent amount of battery drain while the phone is asleep.
But 3G signal is great. That is the green line in the battery graph. You can see that when I switched to 3g (or HSPA as it really is) the battery drain while idle reduced dramatically.
So if you are in an area like this and you really need the battery to last longer, put it on 3G and it should help a lot. At least until T Mobile increases the LTE coverage, which I am sure they will.
And for when you need the LTE speed, I have an LTE button on my quick settings panel to activate it so I still get the speed when I need it, but not the battery drain when I don't. (Note, I'm using cm10.1 rom. I am not sure if the TW roms have that quick setting button available. But it can be done in settings.)
This option is not for everyone. But if you are not a heavy data user like me it might be great for you.

There are many apps in the Play Store that allow you to do that.

Never thought to have data go to 3g and lower.. I've always used tasker to disable... no off screen email but I go in and manually check it anyways so it works for me. I get 2.5 hours out of 1 percent when my device sleeps.
