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 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!

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?
I have flashed several roms, radios, and kernels to this phone and none of them will roam. Not even stock out of the box. I also have a photon and I can be in a location with little to no sprint service and the photon will roam on cdma with full bars but the epic touch wont leave sprint to roam. Db never makes it above -100. I don't even know where to begin. I have tried forcing roam, but nothing. I have went through all the settings for network and mobile data/voice every option I could think of and the phone is still stuck on sprint

For me whenever roaming control is on, it never really activates roaming and if it does the signal still is bad when the person next to me on verizon and or tmobile has all 5 bars.. So either roam control doesnt turn on fully or it doesnt want to connect to better outside network towers ??
roam control doesn't work in all areas with Sammy phones. Frequency for roaming is different. Roam control site explains it better than me.

Btw roam control dies work. The problem is the prl. If you are using a normal pro it will only roam on 1x. You need a business prl like from korey's thread.
Sent from my PG86100 using Tapatalk
Also, Sprint prl's will use VZW for roaming as a last resort.
Download Net Monitor and check to see who you are actually roaming on.
What PRL and what location are you at?

Yep, that is the problem that I see most people having. They download a pirated copy of the app and wonder why its not working. The developer has implemented something to disable the roaming function with pirated versions. To use Roam Control to its full potential, either buy the app or go on a hunt for version 1.4.
I have the same problem.....p***es Me off,but im trying different modems,hopefully I get better signal or I might just try flashing my phone to boost or cellcom

Are you sure that you are actually switching over to roaming? Do you see a small triangle next to the signal bars.
First off, your never going to roam on T-mobile since they're GSM.
Samsung phones have a "bug" where they cannot roam on the cellular band; they will only roam on the PCS band. Your friend on Verizon is probably connected to a strong cellular band signal and when you force roam your connecting to a crappy PCS signal.
I have a paid version of the app. On my photon which is a sprint phone will roam perfect. Tested the app on that phone and it made no difference, the phone already roams like its supposed to. Same house the epic touch won't leave sprints network. I can barely hold one bar with every roam setting in thx phone turned on. I installed roam control again from the market onto this phone and even the app can't get it to roam. Still 3G at one or no bars on sprint network. Also what are these prls I keep reading about on all these roms. I know I could search the forums and find an explanation on what they are how to change and whatnot but are these codes that important? And would that effect the phones roaming and signal strength? Because even with the photon not roaming and using sprints network I can hold a steady 2 or more bars but with a sucky data speed

Could it be because im inside and its trying to switch between H+ and LTE all the time? Is there a toggle i can just keep it at H+?
I would find that unlikely but you can try being on HSPA only and see what happens

You can go to settings, more, mobile networks and switch from gsm/lte or just gsm. But I have not dropped data other than H to 3G every once and a while in weird areas but not a whole lot, but talk to bell online chat and see what they say.
Sent from my SAMSUNG-SGH-I747 using Tapatalk 2
what do you mean it loses signals?
does it get disconnected to the network completely? and you get the emergency calls only message?
because that happens to me as well. I am also thinking its because the phone tries to switch from LTE to H+ over and over.
I think I'm getting the same problem, a fee times a day i get zero signal, then all of a sudden it pops to full signal, without moving the phone. When i lost the signal, it says emergency calls only...
Sent from my Nexus 7 using Tapatalk 2
I had the same issue downtown Ottawa. I switched to HSPA+ only and the problem went away. Turned out, Bell was working on their LTE stuff and that was going up and down and so did the phone. Now, it is all good.
Try having Bell reset your connection from their system....then get them to give you a different SIM card.
I had the exact same thing happen to me when I was in a zone not completly covered by LTE, whenever my phone lost LTE connection I would lose all signal for a bit to eventually drop back to HSPA+, I simply disabled LTE until the coverage reaches where I am completly.
Yep, disabled LTE for now. Problem has gone away and battery life fixed
me and my brother have had the issue in dowtown ottawa on rogers. seems fine in my apt in the market but on a patio and at a restaurant it just wouldnt work!! couldnt send texts, or receive, couldnt call, sometimes it showed i had full bars and lte but couldnt do anything. my brother complained about this the day before. i will try disabling lte next time

So Raleigh finally has a few LTE towers active, and with the help of Sensorly I know where those are.
Seems though half the time it doesn't connect. I know it's not a tower issue, as if I turn on airplane mode on then off it will connect to 4G just fine.
I noticed under settings there's the Sprint optimize connection thing. Turning that on/off seems to have no difference.
Is there a file somewhere that I can edit to change the default connection lookup time? Since LTE is different from WiMax, where you don't "really" have control over the 4G radio, I'm assuming there is a time-out feature. A specified amount of time it takes before looking for an LTE signal. If this is true, is there a way to edit that to speed it up just a little bit? Say going from 10 minutes to 5 minutes? I'm not worried about battery life. I can't kill this thing in a day anyways and I'm lucky to have access to power 7/10ths of my work day.
Also I'm not sure if this is related to MA7, Deodexed stock ROM, or what but I am having issues with coming off Wifi to 3G, and 3G not being active. Have to cycle airplane mode a few times to get it to work.
I'm rooted with stock and although my my phone switches fine between Wi-Fi and 3g I did have a little trouble switching between 3g and 4g. One thing I did that helped was switch the mobile network to 3g only then after it reboots switch back to the 3g,lte network, after reboot run a prl update. That may fix your issue. The problem may also be Sprint is still not done boosting the strength on the 4g towers and is still testing them.

Folks,
Your phone will connect to the strongest signal possible....if LTE is stronger it will connect and vice versa. When you toggle your airplane mode or power off/on it scans for everything at that time and will scan LTE and connect even if its weaker. As areas become more saturated it will connect easier
Edit:also turn off the sprint connection optimizer

I understand that. My question pertains to how long in between scans for LTE (I've read anywhere between 10 minutes and 30 minutes) and whetheror not that time can be changed on a rooted phone.
What exactly does the sprint connection optimizer do?

Well the note 2 scans pretty quick...id say <5 mins or so. I can leave my station where theres no lte and drive 1-2 miles and be connected. Once it loses lte it seems to reconnect in under a min. The connection optimizer scans available wifi hotspots and attempts to offload your data on wifi networks you have used before. Ive heard that it connects to wifi spots that you havenrt xonnected before but I havent seen this. It will cut your wifi on periodically to check and so forth. I uncheck mine and freeze it in titanium. ...personally I think it isnt needed and is a waste.

Not true. Your phones data connection is set in a priority order. Wifi is #1 and overrides all, 4G is #2 (will override 3G and 2G even if it's a crappy 4G signal), 3G #3, followed by 2G as the final drop back if none of the others are available.
