My phone is sitting next to me at work. Barely using it, but it's just draining, at an alarmingly quick pace.
I have bad reception at my desk at work in LTE. As you can see from the pic, it's constantly looking for signal. Is it normal to create such a battery drain in that scenario?
I used to force my older android device to use 3G. Any way to do that? I don't see that option under mobile networks as I had in my older phone.
Go into your settings app, then into more, then into mobile networks, then change preferred network type from LTE to 3G.
I don't have that option, unfortunately. I had it on my old phone which was running a custom rom, but not on the at&t moto X.

Try going into the dialer, hit *#*#4636#*#*
To menu, phone info, scroll down to LTE/GSM Auto and choose wcdma preferred.
I have the normal menu on the XT1092, so I can't say for sure it'll work for you.

Thank you. I also grabbed an app called "4G Switcher" which does basically the same thing (allows you into that menu without using the dialer). I currently have it set to "GSM Auto" - does that accomplish the same thing? It's definitely not on LTE, as Speedtest indicates ~5 MBps download speeds, and the icon says "4G" instead of "4G LTE." How is WCDMA different from the GSM setting?

WCDMA is the European standard for 3G, speeds up to 30Mbps.
When saying GSM you generally mean 2G/EDGE. 0.12 Mbps(?)
But I don't know all of the settings in that menu, there are many that will probably lock you out of some bands you might want.
You should experiment and see what you get.
WCDMA preferred is what I've used for the past several years on android phones, this Moto X is the first where LTE is actually useful. =)
The "low" bandwidth LTE (800/900mhz) uses less power than 3G mode here.

Got it, thanks. WCDMA mode seems to give me better signal, so we will test with that one. Will report back with how this performs at work, hopefully helps the battery life.
I have much better signal at work with wcdma compared to LTE. But battery still seems to drain quick. I'm at 6 hrs off battery with just under 1 hr SOT, and at 60% already.
Screenshot. Android OS and System seem go be taking a lot too.

Your problem is not bad signal but an app which keeps your phone awake, unfortunately it's rather difficult to hunt down on kitkat and above without root, the only way is to start uninstalling apps until the problem disappears.
Hmm, I have very few apps installed actually, and just Facebook and Gmail syncing. Are there any apps that can help identify the drain (GSam?)?
Don't look further, Facebook is known to be one of the worst android app for android

Hmmm interesting. I'll try uninstalling Facebook and repeating the experiment tomorrow at work, just to see if it drains slower. I wonder if auto-sync can accomplish the same thing instead of removing it entirely, but will try this way first. Going to take off a few other unnecessary apps as well, and will install GSam to see if it helps identify anything.

I had that before, it was the Moto app for me.
Go to google play, search for the term "motorola" straight up, and click your way through the updates that are available.
If you have never done this, there's a sensor firmware update and some other goodies.
After updating everything, go into the app "Moto" and clear cache and data, now re-run this and set up your stuff.
After this android os and system is always lower than cell standby.
And there's the usual GPS setting, go into GPS, and disable it fully.
Don't allow google to use passive mode, set it to "Device only"
ed, I have facebook installed but every single notification disabled.
It still runs a bit in the background, but not nearly as much. Not enough for me to notice a battery drain at least.

Shadow, that's very helpful - thank you. I had a lot of updates to do, and as you said a sensor firmware update. I disabled a couple Motorola things like Connect, Help, and Spotlight Player - but I do use Actions, Voice, etc. Updated everything, cleared data and cache, will see today how the battery performs.
Yep my GPS is set to device only, and interesting feedback on Facebook. I will keep it off the device today for testing but do want to put it back on as I use it on a regular basis.
Thanks again, will report back with my findings.
BTW how did you figure out it was the Moto app?

Actually, I wanted to kill the always on voice activation, it bugged out and wouldn't let me disable it after I switched back to Swedish system language, I was testing the voice recognition in english a few days.
So I wiped it, and suddenly my system and os battery drain dropped like a rock. =)
I have even enabled car detection and all the sensor stuff in the Moto app, except voice obviously, and it doesn't affect the battery any more.

Ah gotcha. I thought all that voice stuff was supposed to have a side processor that drained no battery! How did you turn all that stuff - disable in settings or disable app entirely? I don't need any of it either, just want to make sure the Moto Display and hand gestures still work.

Hello I seem to have a problem and I am hoping someone can help. My phone is rooted running Modaco r20 Desire Rom. Radio is ERE27. I have a strong 3G signal in my town with T-mobile. My problem is that for some reason whenever I use data (internet,online gaming, searching using apps etc) the icon will stay on 3G then switch over to H. Sometimes it will stay on 3G and it will not allow any data. I know about the EDGE to 3G issues. I don't seen to have that issue. Can anyone help and or know why this happens?
Usually, when browsing the internet or anything is being downloaded at all - the 3G icon will switch to H. Really only in custom ROMs though, I don't really believe this happens in the stock ROM.. it's not a bad thing or a problem, at least not for me.
Data doesn't completely shut off for me though.
The "H" means you are achieving an HSDPA connnection of sorts. Stock does not have this icon in it, since HSDPA is a form of 3G and they didn't want people getting confused by it switching from 3G icon to H icon.
HSDPA is faster than basic UMTS, aka "3G"... so it is not a bad thing at all.
No idea why you loose your data connection all together when it switches, since it isn't doing anything other than recognizing you have a faster data connection than basic 3G, nothing is actually changing to cause you to lose your connection since it is still the same connection.

no it is not...
mine does the same thing... i have to twiddle my thumbs and wait when it switches between UMTS and HSDPA... they are different frequencies just like EDGE is on a different frequency...
I don't think UMTS and HSPA are on different frequencies, the same two frequencies are used (alternating for downlink/uplink) for both, those are 1700mhz and 2100mhz.
For some reason I don't have this problem on Long Island, but when I'm in the city this happens the whole time. Might be something to do with the way the network is configured. Basically whenever data is in use, it just says 3G, but as soon as I browse to a site or actually use data, it switches to H within a second or so. I think a stock ROM would technically be doing the same thing, but it just won't show the actual switch, as it doesn't differentiate between HSPA and UMTS in the top 'taskbar.' Although it would probably show this in the phone status screen under settings.

The "3G" to "H" (and back) is a "red herring". If it's "stuck" on 3G when you're trying to do data, it means your handset is having issues communicating in the AWS bands for 3G (2100/1700) and the handset hasn't dropped back to GSM/GPRS/EDGE (1900) yet or is attempting to switch frequencies and the associated towers aren't cooperating with the hand-off or the hand-off is failing.

I'm in times square. My phone has never switch to UMTS. Either HSPA or EDGE.
also while it's idle it will only use 3G
it will switch to H to transfer data, then revert to 3G

Which Modaco ROM? If it is Desire, you have to flash the newest radio, and do it after flashing the ROM itself, otherwise you will have major Radio issues... at least that is my, and a fair number of other's, experience.

Yeah its Desire rom. I have radio ERE27 right now
Try upgrading to the newest one, 32.26.00.24U_4.04.00.03_2:
http://android.modaco.com/content/g...-online-kitchen-optional-root-insecure-himem/
Make sure you have at least 50% battery before flashing, just download and flash via recovery just like a ROM, do not panic, ever, during the process and do a battery pull, just wait for it to flash, then ask you to reboot, reboot, it will then do the actual radio flashing (you will see a box with arrow screen for a couple minutes) it will reboot on its own into recovery, say "writting" cache with a progress bar for a few seconds. The bar will go away, but the "writting cache" text will not, don't worry it is done, just reboot and then double check it flashed by going to about phone, software, and checking baseband version.
Just remember, can't stress this enough, do not pull your battery at all during this process. And make sure you have at least 50% battery before starting. Flashing a radio is the only way you can brick an N1 right now, and only if you pull the battery during the process, or have a bad download. Speaking of which, I do recommend checking the MD5 sum to make sure it is a good clean download.

I'll have full bars for 3G and when I goto check the market or anything internet related, the 3G will switch to H and work or stay at 3G and pause with connection error, retry or cancel.
I started having this issue after updating my factory stock radio. Anybody know which one is the stock/default radio IMG is? I'm thinking of downgrading and seeing what happens.

So the *#*#4636#*#* GSM battery fix has been all over but I am unsure if it actually changes anything.
Here is what I have found:
I do the the *#*#4636#*#* dial, go to phone info, hit menu, then select radio band, force close, change to CDMA auto (PRL), then hit home.
Now here is the problem. Hold down home for recent programs and go back into testing (I found doing the *#*#4636#*#* lags and kills my phone sometimes). Hit Menu, force close, and take a look at what the preferred network type is: GSM.
As a test to the “visual glitch” theory, I changed the type to GSM/CDMA auto, when I return to the test menu, GSM/CDMA auto stays. So this menu is showing what it is actualy set to.
Every time you go to menu and select radio, the force close shuts off the radio and the menu says GSM. Is there really a “visual glitch” or does the GSM show because of the procedure followed??
Also it is referring to the PRL, which is the roaming list provided by Sprint, which is not going to have any GSM listing anyway.
I am not an expert by any means but there is more to this mystery then everyone is lead to believe. Battery life is a big issue and I am unsure if the “solution” is actually helping people.
The Time Without Signal fix works. Here's why.
Hitting menu and causing the force close causes it to reset to default. If you actually set it to GSM auto PRL, it is reading the Sprint towers off the PRL, and searching for a GSM signal at the same time. Try changing it to GSM only, and seeing if that causes the TWS to rise dramatically.
This solution was only meant to help people who's phones were searching for a non-CDMA signal.
Do we know if this is still a problem with the offical Sprint 2.1 update?
It hasn't been a problem for a few months now.

You should follow my guide on how to reduce it. It's in the sticky wiki.
Doing this will boost call QUALITY & response time between the tower and your phone. It also seems to cut alot of the background noises as well.
1. open dialer
2. *#*#4636#*#*
3. change GSM Auto (prl) to wCDMA preferred.
4. click Enable QXDM SD Log
5. SMSC: -refresh, then long hold update.
6. Scroll to top, run ping test...
7. Once done, hit HOME.... NOT BACK!
if you run into any issues, swap back to GSM-Auto (prl) then update your SMSC number again. By default it loads as GSM-Auto, so if you reboot, you will have to swap it again.
-=-=-=-=-=-
Ive been running like this for around 10 days now and & definitely notice a good gain in call quality, not only in response time, but clarity as well. I don't get any background static and outside wind/other noise seems to drop as well also.
-Leave me feedback and let me know what you think if you try it.

WHAT IS wCDMA... and why is it better than GSM?
-=-=-=-=-=-=-=-
wCDMA (Wideband Code-Division Multiple Access), an ITU standard derived from Code-Division Multiple Access (CDMA), is officially known as IMT-2000 direct spread. wCDMA is a third-generation (3G) mobile wireless technology that promises much higher data speeds to mobile and portable wireless devices than commonly offered in today's market.
wCDMA can support mobile/portable voice, images, data, and video communications at up to 2 Mbps (local area access) or 384 Kbps (wide area access). The input signals are digitized and transmitted in coded, spread-spectrum mode over a broad range of frequencies. A 5 MHz-wide carrier is used, compared with 200 KHz-wide carrier for narrowband CDMA.
Summary:
1.WCDMA is a 3G technology while GSM is a 2G technology
2.GSM is slowly being phased out in favor of CDMA
3.GSM is still more widespread than CDMA
4.WCDMA and GSM uses different frequency bands
5.WCDMA offers much faster data speeds than GSM
6.WCDMA would soon replace GSM
It's stated in this thread that it's non-dangerous as you can just reboot the phone / change it back. I'll just pop in here with a word of caution: I couldn't.
I have received a significant increase in speed and response time on my data connection since performing this change. I've received significant performance/quality on my conversations over the phone. I can still receive SMS's, however I can no longer send any...
When I attempt to change it back it's already on "GSM auto (PRL)", and I can no longer get the "Enable QXDM SD Log" button when changing to "WCDMA preferred".
I've attempted to change back by ignoring the step that included the "Enable QXDM SD Log" button, but to no avail.
I've attempted to re-flash GOTs 2.2.1 as that should include the most partitions of any flashable ROM, and I had hoped it re-wrote the radio. Apparently it did not.
I basically have a looong night of debugging ahead of me Such is the nature of modding.
[edit 1]
My phone is a UK Milestone, one of the first models. I am not sure of the technical term for the model.
[edit 2]
Solved it.. The SMSC number was set to 5p41450522.
After some time I found the SMSC (SMS center - responsible for sending SMS on the network) number from my provider. For TDC in Denmark it's +4540390999.
Pressed UPDATE and home button.
NOTE: For non-english phones the menu is translated, and as such the 2 buttons next to the SMSC field may be named the same. The left most button is UPDATE, the right most button is REFRESH. Some languages tend to translate those two words to the same.
The default setting, GSM auto (PRL), will switch to wCDMA when there's a load on the network connection. That is, with a call, a download, or something similar, the phone will accomplish exactly what's been done manually.
The difference is that with this setting, the phone will almost always prefer 3G, meaning you won't have the benefit of using the less power-consuming connection when there's very little load. There has to be almost no traffic for it to step down to 2G.
It won't affect call quality, and if it does, I'm going to go out and state that it's simply a placebo effect. Regardless of which setting you choose, call quality will be the same, as both will have the phone switch to 3G during a call anyways.
One thing you may notice, though. With it set to WCDMA preferred, you may notice a less reliable data connection, and perhaps some dropped calls if you're not in an area with good 3G coverage. GSM auto will prefer 2G network when reception is low, helping to ensure you stay connected.

Tag, I did this to see if it fixes my SMS problem.
Thanks to your "wonderful mod" sending SMS didnt work anymore. Make sure you put in the correct SMSC number of your SMS Service Center!
I can no longer send any txt messages after applying this mod, I did a factory wipe and still can't. Any way to revert this?

t mobile +2063130004
at&t +13123149810
sorry to any issues you may have recieved whole doing this... but as always, full nandroid back- ups should be done before adding a new mod. yeah I realize I said there was no harm if this didn't work out, so I'm sorry for that.
Anyways just google for "(your carrier) SMSC address" then correct it if you are having issues.
Can somebody be so kind and upload stock buid.prop for Bell AHD?
Wanna see differences between the AT&T and Bell setup - looking for way to enable network type switch in phone info
Thanks
here you go!
please extract it to get the build.prop for a bell AHD
Well, I tried replacing build.prop in hope that will enable band switch but it did not
I would really like to have option enabled in settings or trough phone info.
In phone info i can switch between LTE/GSM/WCDMA and LTE/CDMA/EvDO/GSM/WCDMA.
Any other choice reverts back to LTE/GSM/WCDMA. I have done EB40 battery mod and I am not worried about battery life as I can pull out 2.5 days on medium usage but 70% of my day I do not need LTE so I was hoping to extend battery life even more by switching to EDGE

Try that app and see if it works for u... o used it on my atrix 2

I dont know what ATT did...
I followed instructions from here: http://forum.xda-developers.com/showthread.php?t=1386383 and I got network switch enabled in settings but when I select GSM only setting does not stick...Reverts back to LTE.
I tried adding ATT 3g APN (wap.cingular) but it wont connect to the data network at all???
Really stuck now.
Generaly I always used 2g data connection when I am at work as I still can get my emails and mms and do some basic browsing and internet radio streaming. Then if I stream videos or download apps or upload large amount of pics I would switch to 3g (LTE in this case)
I wonder does it have anything to do with account provisoning for LTE???
I really would like to have that option enabled and working. I know ATT is in the process of phasing out 2G data on account of LTE but as long as it is available I would like to use it...
After completing the steps in that post and deleting the backups change the operator to maritime. Successfully dropped down to 2G /EDGE. Thanks for this thread. Was hoping someone would post a bit of information on it. Here's some screenshots.

Great - I did it too, bad thing it does not stick after reboot - reverts to auto select network but its better than before
I wonder what the heck is Maritime in network selection...
Anyhow will look more into keeping manual network selection after reboot.

Would have never have guessed to search for networks and select Maritime. Thanks for the tips guys. I can now force 2g at work.

Maritime is another AT&T network. It was actually the default on my Atrix 4G. Sadly, the Atrix HD doesn't display the code for each maritime network. Shouldn't be to hard to switch the default to it if we knew which code it was. Setting the default to Maritime wouldn't help considering there's 3.

Very interesting. If set to 3G only on Maritime it displays the 4G without LTE. Through Phone Info, it shows that I'm connected through HSPA as well. Selecting Automatic sticks with HSPA unless I get better LTE service. Seems like 3G is a good balance between speed and battery life.

Is there any proof that disabling LTE saves battery life? In older phones, disabling 3G would save battery life because there were separate chip-sets for 2G and 3G services. That isn't the case now, a single chipset handles all signaling. Thus, there are no chips that are powered down when 4G is disabled. I would expect battery savings to be minimal.
Additionally, because of the increase efficiency of the LTE network (combined with less network loading), your phone will have an open data connection for a much shorter time, when transmitting data.
I've got my AHD on the AT&T network using a StraightTalk AT&T sim. $45.00 unlimited everything. With the APN that straight talk uses, it never searches for LTE. Just on 4g all day long, with no LTE searching at all.

Guys you need this app

No need to edit build.prop or root.

Well, I'm going on 4 hours of screen on time, 13 hours of listening to music, etc and still holding 62%. That's from jumping between 2G and 3G on an as needed basis.
--edit--
Seems the jellybean leak comes with this already done? Able to switch to just about everything. Getting HSPAP instead of HASPS a well.

I am noticing on T-Mobile that my cell signal is constantly jumping between 3G, H, H+, and 4G, which causes a bit of battery drain. "Cell Standby" is the second highest process listed in battery stats.
I have my APN set to fast.t-mobile.com, and my network mode set to 4G (preferred)/WCDMA/GSM
Anyone else experiencing the same thing?

Did you manually set the APN? Or is that an automated address?
I don't think having a high "Cell Standby" is a bad thing, unless it's listed under wakelocks, but that seems to be like impossible.
"Cell Standby" is like the highest process for me and I don't have any problems in terms of drains. I'd suggest try looking for another APN in the list.
Just remove the one you're in now and try rejoining it, or another one.

I used the "Internet Settings" option within Settings > Wireless & Networks.

Yes I know, but did you enter the APN settings manually, or did you just choose from a list?
Either way: Choose to forget the current APn and try reconnecting to one.

I did not enter them manually. I chose T-Mobile when it popped up.

Have them push an update to you for the cell towers. On Sprint, it was called a PRL Update, not sure what it is called on T-Mobile(I recently switched, and am using them now). Mine jumped around like your's, but they pushed the update, and after a few days, I get more bars, and a pretty solid data type connection.
I don't believe GSM uses PRLs.

I am not sure either, however, over the phone with T-Mobile tech support, they pushed out an "Update" of some kind, and I saw a difference.
