I got a weird one for you guys. I had LTE on my nexus 4, but after tethering for awhile, my LED started flashing red and the phone got hot. So I turned off tethering, but my LTE became intermittent, and over the course of the next day, I lost LTE connectivity altogether, even if I set it to LTE only, I wouldn't get any signal. This is what I've tried, changing different hybrid radios, changing ROMs, factory restore to original ROM. The other symptom, and the one I care more about, is that my battery now drains pretty quickly, whereas it would last 3 hours of screen time on before this incident, now it lasts less then an hour. And it seems to drain while the phone screen is off. Anyone have any ideas what it could be? Did I burn out my LTE modem?
I think you need a new battery.

I have a feeling it has something to do with the modem. Day 2 with the damaged phone reveals that my signal will go in and out, sometimes it will be on 3g, sometimes on edge (even in 3g areas). If that's the case, a new battery won't necessarily help.
Now 3g is gone completely. I can only use 2g. Anyone else run into this problem?
I had this problem a few years back. It was the wireless provider who was adjusting my internet speeds. After one simple call they stropped doing this and my phone was always connecting at 3G (I don't have the LTE hack installed)

Hi All,
Wondering if any of you have this problem with your trinity. I usually power off the screen and keep in the pouch. It tends to heat up alot on plastic and the battery drains extremely fast as if the screen is on.
But in reality i haven't switched anything on (GPS/Data Connection/Wifi/Bluetooth).
Anyone know whats going on?
By the way my ROM is 1.23.707.6, Radio 1.35.00.11, TRIN100.
Are you sure you haven't turned on a GPS app by mistake- GPSInfo etc?
Can you check Settings/Memory/Running programs and see if anything is listed when the battery drain occurs. GPSInfo doesn't close by itself so if running, it will keep the GPS awake, and drain the battery. Have you tried putting it into 'Flight Mode' to see if that fixes it?
When you power off the screen, are you using the power switch ( top right side?)
Are you in a marginal 3G region? If so, the device will constantly search for a 3G signal and switch from GPRS to 3G many times. 3G drains the battery quckly anyway, but the constant signal searching drains it quicker. To test that, go to Phone/Settings/Band and switch the upper box from Auto to GSM.
Hi NeilM,
Thanks for your reply. Yes I am using the power switch and there are no programs in the memory. I just switched teh Band according to your recommendation but I set it to WMCDA instead. Seems to get me stuck on "3G" while with GSM I can only get "E" - Edge/GPRS. Also I set the GSM/UMTS band to UMTS (2100+800).
I am charging it now so I will check it out tomorrow to see if it makes a difference.
Thanks.
WMCDA is 3G only, so setting to that will result in no signal if you are out of 3G coverage. Setting to GSM will mean you can't connect to 3G, but will still continue to get G or E, which consume much less power.
The GSM/UMTS band can be left to Auto.
If you find that the 3G switching is part of the problem, using a small program called Bandswitch will allow easy switching between the services; better still, it's free!
You may want to open up your case and check your battery. There may be a short on the connectors somewhere which is causing a massive drain. Tell tale signs will be burn marks on the battery.
I've checked the battery seems to be fine. But I decided I will send it in for warranty and got a replacement. Just charging the new one. Will see if it helps tomorrow.
By the way I looked in the WM6 threads and found this:-

I have the same problem occasonaly. Think its the band issue because I had it in a concert where my signal strength was not good
yeap i can verify that now. My battery power is normal now. The tool Comm Mgr Pro is also useful to switch between 3G and 2G when I require it. I get Edge when I am 2G. While this helps, but probably won't be able to receive 3G video calls when I am on Edge.
Also I don't know why this never happen to my Hermes (O2 Trion which I bricked). One difference i noticed my the hermes is that the band only changes from G>U, Didn't have the switching from G>E>3G>H. Maybe its the new software i saw mentioned a couple of times in the forum.
So where I work I am roaming most of the time, so the TWS goes up the sky, and the battery down to hell, is this normal? running Fresh 2.1
Yes, unfortunately it is normal I have a pretty weak signal in my house, so my battery only lasts about a day if I'm inside all day. Since the weather is getting nicer though, that will change
Basically the phone is searching for the "home" network, thus using more battery.
When I travel to my brothers house (no sprint coverage) I would switch it to roaming only network (on my Diamond), thus it saved the battery a lot as it wasn't searching for the home network.

Simply put, yes. Sprint phones look for two signals at the same time, a roaming and the home (Sprint) signal. When your roaming, the phone is constantly trying to get back on Sprint's network. So a way to combat this is to turn your phone to either home only, or roam only.
If you need more help on this issue let me know I know my way phones.
Hey, I am trying to figure out why my battery drain is so high. Part of it is the display (trying to work on that too) but I see that my "phone signal" is quite bad. I have a feeling that this is draining my battery.
I have attached my battery stats. Do they look normal. And does the phone signal look normal or below normal. I think it is worth noting that I almost always have 4 bars of signal so I am not sure whats going on. I use my phone in Canada on the fido/rogers network (i believe it is the same as At&t in the states). Is there another radio I can flash or something if this is not normal (which will still work with my phone/network)?
Thanks a lot
Reports are that using 3G a lot drains the battery immensly.
Try switching to use 2G only and see how that affects your battery life.

I dont think it is worth it to pay $30 a month to use 2g networks. I will try to turn off the 3g radio when on wifi though. And maybe only turn on 3g when i need it. As for the phone signal bar. Is it the same or worse than what you guys are getting?

It already works this way. Wifi is going to be your best bet to lessen drain if available (both in standby and when using data - just make sure you have the sleep policy set to never).
If you have poor signal you are going to murder your battery - no way around it. The radio will boost power (Gain is adjusted automatically) in an attempt to get a better signal - and constantly search for a better one. So if you are bouncing between no service and 1 bar or even with just a weak 1 bar signal you are going to see atrocious battery life. There's not much you can do there except potentially switch to SIP in those times if you use a SIP provider.
If you are sitting with 4 bars then you should be seeing decidedly better battery life. What is the actual time the display was on in that screenshot?
I use 3G and its fine. What radio are you using?
the choices are: JK8, KB1, KB3, KD1
you can find them on the dev forums

that looks pretty normal for that kind of usage. id say that you were a moderately heavy to heavy user.

I usually have about 3-4 bars. The time on for the display was probably just over 2 hours (judging from what it is now).

I agree. you're a pretty heavy user So far different radio doesn't drain battery, but only the difference of data connection speed cap.

Yes I do love android (been tinkering around since the g1). I do realize that I am a heavier user than the average person but it might also be that I recently got this phone so I am using it more.
Aside from that, does everything else seem normal?
"Android System" should not be taking such a high %. It should be about 1-2%.
There is (was?) a bug that causes high cpu usage (and shows as Android System) when wifi is on, but not connected to a network.
Another thing I can think of and is something I've experienced, is that sometimes you get an IP address from the mobile network that has a lot of noise, that is, it's an address someone has likely used p2p programs with and there are lots of connection retries. You can see it because the green arrows don't stay dark for more than a couple of seconds, and it kills your battery quite fast. Reconnecting to get a different IP address is the only solution...
Also, bluetooth may be a factor...

Blutooth is always off unless I need to use it (which is rare). I am not sure how to make my mobile network connect to a different IP adresse, would turning it on and off do the trick?
Being in area where there is low/no signal also causes my battery drain to increase by a lot! Which sucks cos where i live i get either 1 or no bars of signal.
Been poking around a bit trying to figure this out. In the last couple weeks my otherwise perfect phone has been randomly switching from 4g to 3g in normally strong 4g areas. My work iPhone 5 stays connected during these times. If I reboot or put it in airplane mode, it goes back to 4g with no issues. Strong signal too.
Got a new SIM on Saturday. No change. Did a factory reset on Saturday night. Still does it after that too.
The fact that it goes straight to 4g and stays after the reboot or airplane mode toggle makes me believe it isn't the phone. Even more so after the reset.
Then I found this- http://www.howardforums.com/showthr...to-3G-in-NYC-Verizon-owns-most-total-spectrum
Is anybody else having this issue? Is there a fix? I really don't want to send this otherwise perfect phone back for a warranty replacement refurb that will only give me the same issue. I also have a glass screen protector on there that I don't want to move or pay to replace.
Any help would be appreciated. Thanks all.
Have you tried to disable Fast Dormancy to test? It should be doing this by design to save power when the radio has not been used after an X amount of seconds. Be warned that disabling Fast Dormancy may lead to battery drain if the cell tower's setting does not match that of the phone

I will try that now and report back. Thank you.
So I recently switched from MetroPCS to Verizon. The day I switched my battery died twice as fast. Cell standby being the problem according to the battery stats. 2nd day, same exact thing. So I did a factory reset. Then the next day the same exact thing. This did not happen on MetroPCS. Also, it seems to only be a problem when WiFi is on, but not connected for most of the day. Which is strange, because I don't see how your carrier would make that a problem. Has anyone else experienced this? Fixed this?

No signal?
Check your cell signal connectivity to see if you are losing signal throughout the day, if your phone loses signal your Cell Standby will constantly search for a signal untill it finds one eating your battery. I have this problem when at work, I don't get signal and my battery drains. I fix this by using Airplane mode when I know I don't have signal. Saves my battery Everytime.
Yeah, would be surprised but Verizon may have worse coverage than the Sprint MVNO in your work area. If your cell radio is constantly hunting, it will chew battery. Have you tried Wi-Fi advanced settings to leave Wi-Fi on at all times, even while the phone is sleeping? May sound counter intuitive, but for me Wi-Fi uses almost nothing battery wise. But like Noland said, if you KNOW you will be in an area of poor reception for a long period of time, airplane mode will save battery. Also check data usage by App. You may have a rogue app sucking bandwidth. Cheers.

Some Verizon members reported poor cell reception with the current radio. I think the January security updates include a new radio. Maybe that will help.
