Losing and regaining signal "bug" is causing significant battery drain on phones
Are you in an LTE area or otherwise get sporadic LTE service?
-- and --
Do you take the subway or frequently go somewhere where there's no service at all?
If you can say yes to both of these questions, you have probably noticed your phone gets hot with no use at all and your battery life takes a big hit.
This is an issue that was discovered and first outlined in this thread. I'm starting this thread so we can raise awareness and hopefully have HTC and AT&T fix it.
This happens anytime you lose service for a certain amount of time and then regain it. This only seems to happen in LTE areas. The only way to prevent this is to enter airplane mode before you know you will enter a dead spot and only disable it after you enter an area you know that has service.
If you don't enter airplane mode, your phone will continue to warm up and suck up battery until you restart it.
We need more people and maybe developers to look into these and report to AT&T. This is such an awesome phone and this is major problem that seems to have gone unnoticed. The other day I was on the subway and saw someone else with an ONE X and thought to myself "Man, this guy is gonna suffer from this bug and he's probably going to be clueless as to why his phone is heating up and sucking battery for no reason all day..." So I approached him and needless to say, he said he noticed the issue but thought it was an app causing it.
If you are both in an LTE area and lose service frequently, please let us know your experience.

i do lose reception in LTE area but only for couple of seconds. it comes back automatically for me. it only happens when it switches from LTE/4g to 3g. now i have forced my phone to be only on 3g , not a single drop since a week. so i think when it switches bands... it losses the connection. poor coding or bad hardware or bad reception ?
I have noticed this on my phone when losing / regaining service and ALSO just when using my phone for an extended period (10+ minutes). My phone easily gets up to 110 degrees (as reported by GSam Battery App) when using it on LTE, LTE+wifi, 3g, or 3g+wifi. Obviously I feel the heat in the famous "under the camera" spot.
*edit* I am running completely stock with no root, custom rom, etc - have been since day 1.

Yeah.. I don't think heating up is usually an issue though as long as it cools down when you're done using it. That's definitely not the case with this major bug. I have purposefully not enabled airplane mode before my subway ride over and over and over to make sure this is really what's causing it and every single time it does it. A bug can be confirmed when it can be reproduced and I could do it every day if I wanted to.
Thanks for starting this up zeuzinn. Agree with this issue, I experience it daily as I commute to work in the subway in New York. I have to always use Airplane Mode, otherwise my phone will be dead in 3-4 hours just sitting there idle with the screen off.
jags_the1 - if you lose LTE signal for a short period of time, it doesn't seem to trigger the issue - for example, I can go into elevators and drive through tunnels without causing the battery drain. But a subway ride does it for me every time.
To add on to what zeuzinn said above - this is an LTE-only issue. If you force your phone to use HSPA+ only, this issue goes away. It has something to do with LTE.
Hope we get a fix for this at some point... hate this bug.
Neo, I do the same. LIRR every day. So no signal from the tunnel until I go topside at 34th. But I haven't experienced this issue.
So I don't think this is an all phones issue.

I am in an LTE area and have not experienced this issue. I do drive through non LTE areas all the time, and go in some basements where it doesn't work, but it always grabs it right away as soon as there's coverage. Noticed no excessive battery draining or heat. Running CleanROM 2.1 with 1.85 radio if it makes any difference.

Vendetta - are you running stock, or a custom ROM? I tried this with stock and various CleanROMs out there, and still have the issue.
Also, what is your S/N? I am on HT25...

Metal - if you simply switch from LTE to HSPA+/3G back and forth, this issue doesn't manifest itslef - it's only when losing all signal for a while.

Even so. There are buildings in the city where I have no service at all and my phone still reconnects right away to both 3g/4g and LTE with no excess battery drain after. Unless I'm still not understanding the issue, I don't think it's affecting my HOX.

I'd love to know what hardware you have and software, kernel and radio, you are running. Also, what is your battery life like in hours? The phone doesnt get that hot. It actually gets slightly warm to the touch , so you might not have even noticed it.. do you keep your phone plugged in at work or something?
Thanks for your input.
I have LTE in the living area and HSPA+ in rest of the house, so I constantly switch between both but, I have never had issues with battery getting warm. It definitely drains the battery faster due to constant switching but, never felt it to be hot.

That's not the issue though. It happens when you lose all service including voice and not during a simple 4G - LTE handoff.
Neo, I'm on HT24 hardware, and here's a snap of my software.
You know, come to think of it, earlier on in my ownership there was a day or two when the battery would drain like ridiculously fast, but I did a power cycle on the phone and it seemed to stop. Nothing fancy, just power off and on. Haven't done it in more than 5 weeks though and I have no issues that rise to the WTF levels others are describing.

Here's my usage today. Morning drain doing video and news and Spotify during the commute, then a clean even descent as it sat on my desk. My signal handoff profile looks like this:
Wake up in 4G
Enter LTE half way through the commute
Lose LTE about 15 minutes later in the tunnel [edit: lose all service]
Regain LTE 15 minutes later when I resurface

This problem is NOT RELATED to only losing LTE. The problem in this thread is when you have a COMPLETE LOSS OF SERVICE, i.e. zero bars, cannot make calls, send texts, or connect to the internet for some period of time. After losing service completely (NOT just switching to HSPA+, that has nothing to do with the problem reported here) SEVERE heat and battery drain are experienced upon reconnecting to LTE.

Okay, let me clarify... When I say I lose LTE, I mean I'm losing all service for those 15 minutes. In a train, under the East River... Yeah.
When I resurface, LTE and everything else reconnects, and the drain looks like what I posted.
So, like I suggested earlier, this is not an "all phones" issue.

My battery life has been amazing, best battery life I ever had with a phone. And I remember someone mentioning exchanging multiple times and having the same problem... I highly doubt it's just our phones. This has been the first sort of confirmation that this may not affect all phones... But... Not that I doubt him, but looking at his history he has more than a few posts mentioning poor battery life... I'm not exactly convinced.
Here's an example of the battery drain that happens after losing service. You can see that after losing service and regaining LTE the battery drains constantly even while asleep, a similar amount as it was when ivwas using it in the subway.
When I started using it again the battery just tanks. It drops 2-3 percent every minute. After a restart the battery is just fine. You can see the difference between the battery drain between similar screen times.

So i am running the new radio that was leaked in the RUU a couple days back. I dont see any improvement in either battery life or reliability of my data connection nor is 4g/3G/1x/noG hand off any better. I live in pasadena ca, and trvl all through LA which is blanketed and EXCELLENT 4G coverage according to vzw.
anyone else? i am running das-bamf 1.5 remix. Also i just got a replacement phone this morning and still the same issues... Bleh. why cant people write radio code properly. Hire more proficient software engineers HTC!
Try just using stock. I used stock everything was a ton better then flashed das bamf and everything seemed to get worse. Just an idea.

Come on. How is it that others are seeing improvements, and that you are not is HTC's fault?
That, and its the FIRST LTE device. Early adopters get to deal with growing pains. Blame HTC all you want, but its no different than buying a 1st gen car.
I'm not trying to be rude, but how can you whine about this, when you arent even running official software?

I am experiencing a completely different situation, I'm just outside of downtown LA and travel to the valley fairly often. My battery life was good to begin with and since flashing the new radio, whilst staying on stock ROM, it has just gotten better.
Currently running on 25% battery, been off the charger for 23 hours with moderate usage.

well you are using all these battery saver stuff like juice defender which i refuse to use because i dont want my data connection to die after 5 mins of the screen being off. i may try another battery sipper kernel or something. the stock battery would never last me the whole day and even with the extended battery i see it go down about 8% an hour
Can't say anything really changed for me. I've been getting good battery life since I got my phone. With the new RUU, it's still the same.
I'm still only on 3g btw, no 4g in Sacramento yet.
i kno right
The TB snaps right on to 4G when I come out of screen lock. No issues here.
Definitely has to be something you're doing, cause the overwhelming consensus is that the battery life us improved.
Best of luck getting the most out of the phone though!

I too am getting very good battery life with the new leak. my battery is currently at 52% and its been unplugged for 10 hours. I leave LTE always on. Ive been using it with moderate usage. Could it be a defective battery? Or maybe a poorly coded app thats draining the battery in the background?
Using Tesla Coil 1.7 here and it works great. I never get reliable service at my house, dont know why even though it is blanketed with 4g according to verizon. I do get better coverage then I did with older radio.
I unplugged my phone at 10 in the morning and eleven hours later I am at 45%. Well at my house I drop out of 4g alot and thats when I loose battery when it keeps cycling between 4g and 3g, but outside and work, school, driving around I get great 4g, I do get decent 4g at home but not nearly as good as I get outside.
When I left home I was already at 85% battery so sitting for 40 mins after I woke up the phone went down 15% it is because if I forget to turn on wifi the phone will keep switching radios if I put it somewhere in my room where I get bad signal, lol.
I was at work for 9 hours and came back I still had 60% battery and I used it for moderately as well and 4g was on the whole time. and used it after I got home. Right now I have it sitting next to me with wifi enabled and the battery hasn't gone down even 1% in the last 15 mins. Plus I am overclocke to 1228mhz on the cpu.

I am kinda new to HTC and such but my advice for you is try to get a new phone from Verizon. There is a way to change back to stock ROM. On a side note, half your Max CPU speed and put it on conservative. That aught to save some juice with very very small compromise to your daily routine performance.

I think my battery life is probably about the same as it was before. Not really sure. But I did manage to get through a whole day at work while playing podcasts through google listen all day.
I've seen a considerable increase in battery usage since the update... Here are my stats... Juice Defender is running but I DO NOT HAVE IT KILLING DATA when the screen is off. I like my data and I didn't buy the phone just to neuter it.
I live in a solid 4G spread and I don't use WiFi... My 4G is way faster than my cable hook up.
I am running the stock leaked RUU. I Only DeBloated it.
These are perfectly acceptable to me for a device of this caliber. This was an average day in the life of my TB.

The data connection being always on is what's killing the battery.
With all the battery tweaking Ive done, Ive determined that having the mobile data always on is the quickest way to drain your battery. At first I unchecked "always on mobile data" and that saved a bit of battery. Im using JD now, and saving even more.
I understand if you depend on Push notifications, this isnt a solution, but for me, nothing is so important that I need to get the notification right away. With data off, you get Calls and SMS when they come through and that's what really matters.
When you power the screen on, the data connection establishes and stuff comes through. What's nice with JD is you can have it turn on data periodically to let push updates come through.

okay is this the stock battery or extended? what other settings on juice defender are u using then if it is not killing data which i thought was the biggest thing it does? those hours are insane.. i cant believe you are getting such great battery life without turning off your data.
BTW i know many people thing some rouge app or something is killing my battery but i looked at both my battery stats and spare parts and see nothing of the sorts. in addition i have had the same apps on my fascinate and OG droid and that was never issue on the phone.
just an update for the day i have used my phone for a few emails, listening to 15 mins of music via wired headphones and a 5min phone call ALL using the extended battery. my phone has been unplugged for 2hr40min and is at 88%
I live in non LTE and have had great battery life normally (w/o LTE switched off)... I am on a two week vacation in the DC area... I was getting great battery life with 4G connectivity... however, since the outage... i have regained 4G connectivity but my battery life is plunging! Anyone notice anything like this? (BTW, i have not made any changes on my phone recently)
I have noticed that whenever i turn my screen off, the phone is showing 0 signal bars and it takes 5-10 secs for it to go to 4 bars, which I have been getting regularly in DC.
I'm having bad battery life to after it. No 4g here

I have had a similar experience, but I also flashed a new rom that same day. I originally thought it was just the new rom. I live in a 4G area.
No change post-4G outage. But my battery was never great before the 4G outage either. Actually, it's always quite sucked.
Odd thing is, DURING the outage, I was either on 1x or had NO data service, and my battery didn't improve then either.

Sounds like a bad battery, I would try to exchange it through Verizon... These phones aren't crazy bad on batteries, most people either have a defect or have too much running at one time...
P.S. horrible service and battery after the outage here in Philly as well, was awesome before...
Sent from my ADR6400L using Tapatalk
I don't think that was the case...when a 4g phone or any phone for that matter gets a signal less than it is supposed to, usually it will continue searching for 4g or 3g. That eats up more battery than even being connected to 4g at all. When the outage happened or I'm not in a 4g area I just turn 4g off.

Mine spiked to about 300mA at idle from 40ish after the outage.
No new apps or settings. Reboot didn't work, setting to 3g only or 4g only or auto in the settings, reinstalling a lot of apps. Nothing I did could fix it, so I had to factory reset. Was a lot less painful than I thought it would be, the Market installing all my apps automatically was amazing to see.
Its OK now.
I'm having the same issue. Before the whole 3G/4G outage i could get 8 hours maybe a little more out of my battery and now that everything is working I'm lucky to get 4 hours at best and sometimes less. I even went so far as to factory reset my phone in an attempt to fix it but still no dice.
It's too hot to hold right now. I walked around my workplace and lost 4g. Nothing is running on the phone. I've lost 20% battery in the past half hour. Something is wrong :/

Not really worth posting... you are doing something to cause the cpu to run crazy.. the only time i have ever got it hot is in games or if im tethering for any extended period of time.

It's possible the tower you're connected to is having issues, causing you to drop back to 3G which might also be having issues, causing your phone to fight for a signal.
Loss of signal makes everything go nuts on a phone. It pumps up the antennae to try and hold on to any signal it can see. This also increases the drain on the battery which generates heat on it's own.
In certain stores, I have to turn my phone completely off (sometimes I can get away with just turning off mobile data), as even maintaining a voice channel is running everything at full blast, murdering the battery and scorching me (not really, but it's still hot).
The phone's SOC should have a safety switch that will force it to power off if it gets TOO hot. Unfortunately for our comfort, too hot for electronics is MUCH higher than too hot for our skin.

Loss of signal makes everything go nuts on a phone. It pumps up the antennae to try and hold on to any signal it can see. This also increases the drain on the battery which generates heat on it's own.
In certain stores, I have to turn my phone completely off (sometimes I can get away with just turning off mobile data), as even maintaining a voice channel is running everything at full blast, murdering the battery and scorching me (not really, but it's still hot).
The phone's SOC should have a safety switch that will force it to power off if it gets TOO hot. Unfortunately for our comfort, too hot for electronics is MUCH higher than too hot for our skin.

yes this is what I have been thinking. Although sometimes I will lose 4g until I restart my device. I think it's somewhat of a software issue over a network problem.

Agreed. I think the problem is along the lines of 4G dropping and the phone is trying to reconnect to it with no success. Is this debug info in the logcat?

It could be. I've never personally had occasion to pull a logcat, so I'm not sure what kind of information gets stored in there.
My phone also did this yesterday while idling except, I did lose 4G, it just wouldn't charge cause it said it was too hot and felt like it just came out of the oven (ofcourse it was mid 90's here yesterday) but IMO still shouldn't get that hot when not in use.
The information about signal should be available in logcat.
My GNex would do this. It would struggle to find a signal and heat up significantly as a result. Battery life suffered. This would happen in my office, but not at home where I have a better 4G signal.
Switching to WiFi at the office helped, but was not really a solution to the problem which certainly can occur when you don't have WiFi available.
As a note the GS3 doesn't do this for me, so it appears that the radios are better in this device. Doesn't help you much, but hey, it could be worse I guess.

This happened with my Fascinate.. where it had died due to running out of juice. And wouldn't turn back on or even charge with the in car charger due to Texas heat being 104 Degrees scorching at that time.. -__-". Had gotten an error temperature message with phone will not turn on/charge due to temperature too high risk...

All phones do this. There's a local grocery store that I swear uses a cell jammer, you get 20ft through the doors and a full 4G signal drops to nothing, not even 1xRtt, not even voice or sms. All throughout the store, until you walk out the door, then wide open signal again. I have seen my battery go down like 80% in an hour in there until I figured it out and started putting it in airplane mode when I go there.

Most buildings like grocery stores and such are built with steel framing, rather than the wood that gets used in regular houses. This creates a faraday cage effect when you walk through the doors. Depending on the construction, it can be very strong and effectively block most signal from getting in.
I have also seen this effect in manufactured homes/trailers, as they tend to use steel framing rather than wood.

Yes it's all do to the radio. Those of us, in a fringe area have to suffer tthrew this. If I'm at my house I can get 4G upstairs and 1x in the basement. This causes the phones battery to drain much faster and cause great issues. I recommend using a different kernel if you are comfortable with it. Also use deadline/smartass . It takes some tweaking, but it will help. No matter what we do we have to face the fact that 4G devices kill battery life.Your not going to get no more then 4 hours screen on time. I love the phone don't get me wrong but the only all day battery phone is the MAXX. I have one also and Motorola s radios are killer lol I wish I could stick my MAXX radios in this baby Another thing its download CPU spy , see if your phone is actually sleeping. It could be a rouge app , contributing to the problems to. I just picked up a 4500mah extended battery , it was the best 30 bucks I ever spent. Good luck and let us know if it was anything else then software related.

Plenty of us here can pull more than 4 hours of screen-on time in a single charge.
I got my AT&T One X a month ago. The battery life has been pretty good, considering the specs of the phone, but I've never been in an LTE area until last night. I'm running AT&T/HTC's stock Android 4.1.1 firmware, and I typically get through the day with no problem and have some battery to spare at the end of the day in an HSPA area.
However, last night, I was in an LTE area for the night, and I noticed that the battery drain was outrageous. As soon as I got into the LTE area, the phone started getting really warm around the camera and I noticed the battery drain was about 10% per hour. I never let mobile data on all the time, I switch it on when I need to use it, and then turn it off when I'm not using it. I was using the phone a bit more heavily than normal, but it shouldn't have been enough to kill 80% of the battery in 8 hours.

On the graph above, I entered the LTE area shortly after 5PM, and you can see where the graph starts dropping quicker, and then around midnight when I left the LTE area, it levels out again. Also, the first break in the mobile network signal was a reboot. Prior to that, the phone was warm all the time and the battery was draining quickly. After the reboot, the phone would only get warm when I was actually using mobile data, but the battery drain was still happening.
I went ahead and did a factory reset on the phone afterward, to see if there may have been a rogue app or setting causing the problem, but I'm not sure the next time I'll get to an LTE area to check it out, but I'll try to report back soon.
Has anyone else had this happen or know of a cause or solution? Thanks.

I dont have LTE with my provider but from what ive read this is normal.
As with many battery issues, you will probably hear vastly different experiences from different people. I've had LTE in my area the entire 1+ years I've had this phone (area had LTE since before the phone was released). I seem to have good coverage in the area, and can often get 48 hours (or a little more) on a single charge with light usage. Drain while idle on LTE for me does not seem significantly different then when in a non-LTE area, or on WiFi (around 2% per hour).
Its possible you were in a fringe LTE area, which would drain the battery much more quickly than an area with good reception. But I would not describe the type of drain you experienced as "normal". Or at least not what is intended or expected.
Since the phone is stock, there isn't a lot that can be done. The stock AT&T ROM is locked out from turning off LTE (which would be one workaround). Flashing a different ROM or radio might help. But those require root, bootloader unlock, etc.
I was in Baltimore, which has had a fairly mature AT&T LTE network for about a year, IIRC. I was in downtown most of the time, which shouldn't be a fringe area. At one point, I did a speed test, and got 17 mbps down and 9 mbps up. I know there's not much that I can do about disabling LTE using the stock ROM, but I shouldn't have to use a custom ROM; this type of drain shouldn't be happening.
I'm pretty sure you can switch LTE off on a stock ROM. Enter the following code on your dialer keypad:
*#*#4636#*#*
A menu will appear, select phone information.
Then scroll down and you'll find a drop-down menu. Open it and select gsm auto prl or wcmda preferred.

You can, but it won't stick, since AT&T has this setting 'locked'. It will reset itself to LTE on at the next reboot.
I'm just curious but did you have the Power Save turned on because when I use Power Save and I live exclusively in an LTE area it would last me about 48 hours on a single charge give or take a little. One thing you can consider is checking to see if you have applications running in the background trying to use your data even though you may have it turned off.

You mentioned you used the phone a bit more heavily but never mentioned screen on time. 8 hours doesn't seem all that bad to me if LTE + 3-4 hours screen on time.
Screen wasn't on that long. Take a look at the screenshot in my first post.
Also, in the meantime I've found an APN setting which is supposed to just use AT&Ts HSPA network and not LTE.

Hows connection stability with that APN? I tried using it back in the day to circumvent at&t's LTE only setting and it was very unstable. A few minutes with the screen off would also turn all data off.

I haven't had any problems with it yet. A few hours with data on the past few days, and I haven't noticed it drop. I'll keep you posted how it works the next few days.
Hi I have a just got a MAXX and updated to 4.4 without root. I found that my battery is not staying up as long as it should, it lasts for like 18 hours. The following are the details:
- Canadian user, Fido sim card, exceptionally bad reception (3 bars tops indoors) (My Phonto Q / Razr Maxx gets full bar when I plug in the same sim card)
- Screen On time at about 3-4 hours
- Rarely turn on data
- Rarely Game on Phone
- Non-rooted
- I keep wifi turned on, connected most of the time
- Use apex launcher instead of MotLauncher
- Active Display, Touchless Control on
- Location Services are in "Battery Saving Mode" (Meaning the phone uses wifi and mobile network to estimate location)
Is anyone else experiencing the same problem? If so, is there any solution? I see a similar thread made early but that is for the Ultra, and even the ultra got around 12 hours of discharge time
Edit: So far based on doogald 's reply, I suspect its the poor reception thats draining the battery, the following photos shows the reception differences across different devices with the same sim card

How long have you had 4.4? When I have updated or changed ROMs, it seems that it takes the software a little bit of time to catch up getting to know the battery.
Sent from my XT1080 using Tapatalk
That's a little more drain than I would see for the same screen on time. Bad signal will definitely drain a battery faster. Forget about stupid bars - what is your signal in dBm? (Settings->more (under Wireless & Networks)->Mobile networks->Network type & strength. Also in settings->about phone->Status->Network type & strength).
The number will be negative. For GSM or CDMA, anything less than (more negative) than -100 dBm is a bad signal and the phone will amp up the antenna to try to pull in signal.
Based on your battery screenshots, though, it's probably not bad signal - I think "cell standby" would be a higher drain if that was the case.

I have had 4.4 for exactly 10 days now, i think everything should be settled by now
My signal is around -97dBm, and it jumps from that to No Service. I dont understand why this phone have such terrible reception though. I had two other phones try the same sim card and they have excellent reception.

Question- are you rooted and using xposed framework? Things that heavily mod the stock system, like GravityBox or Xblast can easily have that affect. Even smaller things like the smooth progress bar can hit it. The more changes, the harder the system has to work to keep up

I have terrible reception at home and work and am getting 7 or so hours of screen on time. Constant switching between 4g/3g and sometimes to 2g.
I'd suggest trying a program like betterbatterystats or similar to see if there's a wakelock keeping the phone from going into deep sleep mode (processor shuts off) when the display is turned off. Also cpuspy will show you if it's deep sleeping. It won't deep sleep while charging btw, this is normal.
For me the problem was the Facebook app. I disabled it and not only did my battery life significantly improve, but so did my productivity Info about wakelocks, if you're interested - http://developer.android.com/reference/android/os/PowerManager.html
Pain in the butt but there's always the factory reset option too.

Not sure why this worked, but it did. At least through one day of testing
I ready elsewhere on Droid X forum someplace I think about draining the battery completely until your phone shuts off and then recharging. It's supposed to re-calibrate it. Sounds sketchy at best I know, but it seems to have worked!
I did this with my ultra followed by charging to full and did a factory reset. My phone seems to be normal again.
