Hello all,
I would like to share with this forum how my battery went from lasting from 7:30am-3:00pm to lasting from 7:30am to 6:00pm(its now 6pm and I'm on 41%).
This is very simple. I went to the settings and checked "Use only 2G networks". When Im working I dont really need the 4G because I dont have time to surf the net. I do sometimes so then I just uncheck the 2G and go back to 4G but in general during the day I leave the "Use only 2G networks" checked.
As I mentioned above I am now on 41% and im home. I left it on 2G because at home I use wi-fi calling so if you dont need 4G data during the day you should disable the 4G and your battery life will be fine.
Hope it helps
Yep I've found that 2g only in combination with wifi calling enabled (and connected) and 50% backlight causes the minimal battery drain. I go from 95 to 70% at work from 7a to 5p.
I haven't removed any bloatware. I haven't changed any wireless settings. I keep my Google account auto sync on, while Exchange sync is set to every 15 minutes. Yet I still have more than 50% from 8am to 6pm.
The only trick is to use it normally, a few calls, some browsing and checking email, a little social networking. Don't use it like you just got it with endless app installing and uninstalling.

I gone from 30% battery to 70%-80% using battery apps not turning off 4G.

all you have to do is alter the thing you have running in the background. no point in having a 4G phone if you're only using 2G.

I am in a "4g extended area" where it constantly drops to 3g and constantly goes in and out. My battery is draining by increments of like 10% per hour while I am not using my phone. I am currently using the tesla 1.5 rom. Is there a possibility there is an issue with my sim card for this issue or just straight up a problem in verizons network? When I leave wifi on the battery doesnt constantly drain on standby any tips would be appreciated thanks
Try the LTE OnOff app on the market. Setting it to CDMA auto (prl) might help in spotty 4G coverage.

If you're not in a good 4G area your battery will die very fast because the radio's are constantly searching and switching back and forth between 3G and 4G, you should either use LTE mode to try and lock on LTE only or turn LTE off completely and use CDMA Auto.
Same problem here as you. stuck in the grey area at home.
I would rather be in s grey area like you than nothing where I am.

I know your pain... I'm exactly 1/2 a mile from the 4G coverage area... im in the "Extended 4G area" and i'll be lucky if I get 3G on this phone let alone 4G... I have to use wifi to get data out there. Which is kinda annoying beacuse if I go to the local grocery store ( 1/2 a mile away ) I get blazing 4G ...
This NEVER happened with my DX or Fascinate... they were both on perfect 3G data.
Hopefully Big Red will "Turn up the volume" and get better signal to those of us on the outskirts of the Main 4G areas.

It keeps intermittently going to 4G and lighting up only the UP arrow, but it's not actually transferring any data -- FB doesn't work, browser, speedtest won't find a server, etc. And then it will toggle to 3G on its own and get the standard .5-ish MB up/down.
I never made the fix yesterday to switch to 3G, figured I'd wait. Wondering if anybody else is seeing this kind of issue. I'm in Detroit. When 4G was up I was getting 30+ MB down as the norm.

Happens a lot... turn data off, then turn it back on...
yeah my thunderbolt also says 4g but only the up arrow lights up and it sits there for like 3 mins until it switches to 3g and starts working again. i only just started noticing it after the outage. is this normal then? how do you fix it when it happens?
This was happening to me all day long as well. It's still really flaky even right now. Also in Detroit.
4G is now working up & down. It was only doing 4G up earlier, so I was forcing it to CDMA auto (PRL) to keep it on 3G.
Sent from my ADR6400L using XDA App
Anybody in Detroit seeing any improvement on this? I tried turning off/on mobile data, restarting, battery pull. Still same issue as I mentioned in the original post. The frustrating thing is it won't just automatically go to 3G when 4G isn't working. I just notice it's switched to 3G randomly at times.
Note: I tried a *228 when the network dropped before I heard the news and before I read that it was a bad idea to do that. Of course now I'm wondering in the back of my mind if that's the reason I'm getting this issue now.
I am on BAMF remix 1.5 with the new radio.
Since the new radio came out, 4g was working pretty good. BUUUUUUUT, since the 4g outage, it's working like pre new radio.
What a CS rep told me was to check the Data roaming feature to fix the problem.
Settings > Wireless & networks > Mobile networks (under Mobile network with the check mark)
Then check the data roaming.
I had the same problem. Where I would lose connectivity to data. However, checking it seems to fix it for me. I just turn on the option "data roaming sound" just in case.
So after the now infamous 4G outage I did notice one important thing on my TB. That day I had the best battery life ever. First time I made it through the day without charging. Hopefully sometime soon we will have an official 4G on/off toggle. I know there is one that takes you to the service menu so you can change the settings but it would be nice to have one that you can just toggle 4G off to 3G then toggle back on without the extra steps.
I'm pretty sure we all knew this was the cause.. look at when the evo came out it had horrible battery life when wimax was still young
And when 3G came out it was killing batteries also... And the circle of life continues...
I'm not sure if I am lucky or what. I am rooted and running BAMF rom. I use my TB just how i used my OG droid and I still get 15 hours on a single charge. I also have full 4G coverage in my area. That might be the cause. I dont see the connection switching around between 3G and 4G. Stays at 4G

Power 2 antennas will definitely use some juice. That's why individuals in non-4G markets (like myself), disable the feature to keep from constant searching.

Agreed. I live in a 3G area, but work in a 4G area, and honestly didn't see much of a difference in normal usage except that my battery would die about 3/4 into the day with 4G enabled. Ever since I disabled 4G my battery lasts the whole day.
I am in a 3g area. Even before the outage my TB was always going from 3g to 1x. I called for help but it only continued. During the outage a fix was posted for a temp. fix to bring 3g back for those in a 3g area. The fix was to apply Rev. A. once I did this not only did I get 3g back but it remained stable and it was loading w a y faster then it ever has before. When I heard the 4g3g problem was fixed I followed the instructions to revert to the original setting. When I did the pages loaded slower like it always did. So I turned it back to Rev A. for good until I find myself in a real 4g environment. Oh and another big plus is that the battery has dramatically improved. So I am very happy leaving it like it is. Sweeet.

Are you still able to do voice/data at the same time running like that?
I did not notice any degradation in terms of battery life after the outage. I'm in 4G area and use LTE Only Mode, so everything is the same as before about 18hrs from a charge.
I did use voice and data at the same time . I was surprised that it actually worked.

They just turned on LTE in my area of Hawaii (though I don't think officially.) But it constantly switches back from 4G to 3G and vice versa. Sometimes it gets stuck with no data and I have to toggle airplane mode. My buddies phone in same spot could show 4G and mines 3G and vice versa. This significantly drains the battery and not a very good experience. My question is I noticed in the app that we used to turn off 4G there is an option for LTE Only, does anyone know of there would be any negative reprocussions on leaving it on 4G only? Like could it harm the phone, would any certain features/apps not work properly, etc?
I ran it like that today. Data connection seemed better and constant. When I looked at my phone throughout the day I did not notice a time where there was no data. My calls/texts/emails came through like normal. Battery seemed better. Left work with more battery than my LG Revolution which is normally the other way around. I did not run into any negative impact with setting it to LTE Only. Can anyone think of any warnings?

All it does is set your radio to only use 4G. If you get to an areabthat has no 4g or wifi you would have to switch back to 3g or 3g/4g auto in order to get data.
No harm, just won't switch out of 4g unless you do it. Probably why the data lock is better and battery life as well.
If you get solid 4G just use LTE only and switch it if you loose 4G.

You are fine running LTE only. All you will get with that is 4G & 1x, so either extremely fast data, or slow as a turtle. I use that setting almost all the time here in Jersey, I live right outside of NYC so I get constant 4G coverage. It does help with the battery life too.
So does turning on WIFI calling when I'm at home connected to my router save battery life?
It all depends I guess on what you are doing while on Wi-Fi

Well that's obvious. But I'm talking about WIFI CALLING. Does turning it on actually not use the cell radio/modem so in turn should it save battery life, since cell radio/modem uses a lot of batt.
Wondering if anyone's had experience in this. This is the first device I've had that supports tmobile's wifi calling.
This is also my first device with WiFi Calling. I always have it on while I'm home because the signal is poor inside my house. Not sure if this is because of WiFi Calling, but when my phone has 30-40% battery left at night and I leave it in standby with WiFi on...I wake up to find the battery dead. So it's possible it's because of WiFi being on during the night. I sometimes put it in airplane mode so battery doesn't drop.
No. Wifi itself sucks mre power than data. Even if your not on a wifi call, your wifi is still on.

I don't think so, but wifi calling is awesome. Free calling FTW

I am not saying you're wrong, but I've always heard it's the other way around, so I did a google search. I found many posts debating this topic, but this is the best answer I've found so far, and it makes a lot of sense:
WiFi drastically saves battery compared with 3G because the radio is so much weaker. Think about it this way: The 3G radio broadcasts powerfully enough to reach a cell tower 15 miles away. The WiFi radio has a range of about 200 feet.
However, the WiFi radio wastes power if you are not actually connected to a WiFi node. Therefore, it's best to turn it off when you leave a hot spot. You can use a utility like "Y5" to automatically toggle WiFi based upon your location.

I don't think so. When I leave WiFi Calling on overnight, my battery is dead by morning. When I turn it off, my battery barely drops overnight.
I notice less battery being consumed when I'm connected to WiFi

WIFI calling burns through my battery at least a third faster than when it's disabled. I only enable it when I intend to make a call; to receive, I use the data/tower.
It's one of those non-exact sciences to say which is better on battery
The GSM/3G radio uses more power when it's active (i.e. IN USE, on a call/data) than when it's not. The difference is actually pretty huge.
Wifi radio when 'in use' uses more power than when it's 'idle' - but the difference is a lot less, due to how it keeps 'in touch' with the wifi router.
The actual amount of power they take depends on distance, radio quality, the weather (yeah, I'm serious!) etc.
There are only few providers who support Wifi calling here in the UK - Orange, I believe is one of them, so I can't comment on actual use. Of course, we have VoIP services, which I use regularly on my Sensation, over Wifi (it won't work over 3g sadly).
Out of interest, if your TMo 'Wifi calling' fully UMA compliant - i.e. can you send/recieve SMS/MMS as well? I'm interested to know if it's a UMA app, or something built into the phone, or a TMo system, or something different.

Yeah, I can send and receive SMS/MMS when I have WiFi calling turned on. I tested it this by turning off the mobile network as well and worked.
Make sure you go into the WiFi calling connection preferences in settings and select wifi only. Sometimes it will leave your 3g on.

It's not quite as robust as the older UMA phones were, however. It does NOT handle hand-off from WIFI to CELL. You'll lose your call if you leave wifi range.
2G is better than WiFi but WiFi definitely drains less battery than 3g/4g
For me, my phone definitely lasts longer when I'm using wifi calling. My g2x generally goes through about 10% of battery every hour.when at home and using wifi calling it usually only uses about 2-5% an hour
Sent from my LG-P999 using XDA App
I'm willing to wager that in areas of strong WiFi, the WiFi calling may save battery power. However, in an area where WiFi is weak or may drop in and out, using the cell tower may be more efficient. However, this may not be true if you're in an area with poor 4G signal (of if it's searching for 4G constantly in a 2G or 3G-only area), as it'll constantly be boosting the cellular radio to search for service.
Turning on the WiFi calling works well for me - I use it at home and at the office, both of which have very solid WiFi. Maybe I'll do a trial tomorrow with it off entirely (4G only) and see if it ends up lasting longer during normal use.
Ok.everyone on this forum are talking about wifi calling I got a tmobile branded device in uk were is the feature to call via wifi.

On a stock T-Mobile USA HTC Sensation 4G, the app is right there preinstalled called "Wi-Fi Calling"
Not sure if it's available for T-MOBILE in Europe.
