Ok Guys,
Kind of a weird question, but I'm using one of the ICS leak ROMS.
With general usage, 4G/wifi, I would get between 18 to 20 hours, which for me is perfectly fine. The more wifi, the more battery time. No issues at all.
Recently, our office moved where we have a dead zone. I do have full wifi access, however being in this area absolutely kills the battery. I lose 12% every hour. As a precaution, I have disabled the mobile data, and confirmed wifi is working. I have confirmed that I can make and receive calls, and send/recivee txt msgs. However, battery results are the same. Is there anything else I could try?
I'm guessing, being in a deadzone, the phone is putting in overtime trying to find a tower....
Anyone have any ideas?
Thanks in advance...
Interesting... On my Bionic with the .232 leak the option to change network types is grayed out. I was thinking if you set it to 4G or 3G only it would save some battery since the analog radio sure do suck down power (if it even tries to use that as an option).
Not sure what to do. Hopefully somebody can provide something useful.

You can definitely try out a couple of apps from the appstore to change your radio settings in one of the ICS leaks. The first is called "Phone Info" and the second is called "LTE OnOFF - HTC Thunderbolt". See if going with 3g (CDMA auto prl works well for me) only will help your cause.
You could turn the radio completely off, but then you obviously wouldn't get calls, texts, etc.
Ok Guys
Here are my findings...
Looking back, it seems during my move, I also upgraded from Eclipse 2.1 to Liquid ICS around that timeframe. So I back tracked and installed eclipse 2.1 and tested. Here are my findings:
on Liquid ICS 1.5mr:
In deadzone in my office, with wifi turned on, mobile data disabled, I get barely 1 hour per 10%
Everywhere else, 4g/wifi mixed. More wifi, the better, but I get roughly 2.5 hours per 10%
I re-flashed Eclipse, this is what I found
on Eclipse 2.1
In deadzone in my office, with wifi turned on, mobile data disabled, I get approx 2.5 hours per 10%
Everywhere else, 4g/wifi mixed. More wifi, the better, but I get roughly 2 hours per 10%
Overall, the ICS battery usage seems to be much better under normal conditions. In a deadzone, seems to eat away much more battery, even when mobile data is disabled. I'm geussing that its prob checking for a tower much more often then GB?
Any help would greatly be appreciated.....Thanks!
Hey Guys
Just wanted to update you on my findings....
Ok, after playign around, here is what i did. With WIFI turned on, I was getting barely half a bar in the radio signal. For a goof, with WIFI turned on, I went into phone info, and disabled the radio, and re-enabled it. within 2 sec, the radio came up and got half a bar again, but a few sec right after that, I got like 4 or 5 bars. After testing in this state, i get roughly 5 to 6% depletion per hour. WHich is MUCHHHH better.
I have a feeling that with WIFI turned on (mobile data seems to be disabled when in wifi mode), and u turn on the radio, that it connects to a different tower entirely. Because when I walk outside, and disconnect wifi, it goes to 4G, but then u can see it go from 4 to 5 bars, to 3 bars which is normal for me for that area.
Hope this helps someone....but it helped me a great deal.

i am not seeing what everyones problem with theire battery is? i havent charged my phone in days. last on the weekend, sunday to be exact. i've been browsing the web, specifically posting on these very forums, downloading programs, texting and talking on the phone as i have no house phone, and just getting to know my phone. using the action screen, ultimatelaunch, etc.
now i do notice i go from 100% to 70% in an instant but once i get under 70%, the phone is a champ. im just not seeing the issue. im getting 2 days easy. no car charger. only time i charge is at home, when im headed for bed. maybe its just me
Specs:
HTC rom (2/15/08)
stock radio
Quick menu
home plugin
action screen
home customizer

Interesting!
Can you provide more details on the ROM version you are using?
Go to Start/Settings/System/Device Information to get that info.
Or if you can post a screenshot of such screen, the better....
However, you failed to mention if you have used the internal GPS at all.... That's when we start seeing poor battery performance... Just after some GPS use and sometimes not even then, but at random GPS uses.
Cheers!
RayanMX
a screen shot of it would be nice
havent used the internal GPS yet.
ROM: 1.62.502.0
ROM date: 1/17/08
radio: 1.27.14.09
protocol: 22.45.88.07h
i get nearly 50hrs with my tilt.. no gps but push is active and bout 200 txts a day maybe 2h of phone calling now.. i drained it down to 0% twice b4 doing full recharges now battery seems to be good. also my screen brightness is set to the 3rd notch.. 30%.
i think the old battery (the one that had plastic on its back) had better life than the new one (the one with a solid aluminium plate) this is my second tilt, and i liked my frist one a lot more..
on my old tilt my GPS worked indoors, and the batterylife was a lot like yours due to the battery.. i get down to about 60% now at the end of the day instead of the previous 70%
the newer tilt just improved the USB plug, the battery (now it doenst get hot), and the keyboard.
I really am starting to wonder about this. I have a TyTN2 and I installed the new Google Search bar for the home screen. I saw a huge difference in how quickly the battery would die. I'm convinced this GOogle search bar was the culprit.
Now I'm wondering if I disable the really awesome HTC interface if the battery will go up accordingly. Worth a shot.
htc home is a battery sucker.. try PDC project digital clock its very easy on batt
well mine does drain a bit, mainly w/ gps.
I wonder what your doing with it? just leaving the phone on? ive got 2 days without using it. Usually mine is streaming stereo music at least and logged into irc all day, ive just been bringing my plug everywhere with me.
Do the new 6.1 roms do anything to fix this?
Also working in the cellular world, (im sure you guys know this already) if your phone is searching for signal where you are most of the day your battery will drain really fast also. When i get somewhere w/ no signal for the phone i shut that part off.
What makes a big difference is the setting of backlight. Just to see the difference, try navigating with TomTom with brightness level 0, and test it with the maximum amount. Same goes for browsing the web. The backlight consumes a lot of power. A lot of people aren't mentioning the backlight setting, so it's really hard to compare these devices with each other. So closet410, what backlight setting do you use? And maybe you should be more specific about the phone call durations, time you browse with it, etc. Some people are calling 2 hours a day or more with it, and some not even 10min in 2 days. So it's a big difference.
u guys r forgetting the most important factor, are u in a 3G area? i have tmobile usa, and only have edge, and easily get 2 days with moderate/heavy use. ive put my wifes atnt sim into my tilt, and honestly was not impressed with the increased surfing speeds. tethering is night and day difference, but not worth the insane battery drain if ur not gonna be tethering..
omar
try using WIFI on full performance... that shu kill it in about 4 hrs...
this is all basic stuff people if you dont use 3G, wifi, GPS it will last for ever! As soon as you use any of those or all at the same time your screwed. also phone calls are the worst second is wifi then GPS and the 3G
i dont use wifi/gps or 3g
I think worse is 3g.
I can listen streaming radio thru WiFi and wireless bluetooth headset for 10 hours
and just 3 hours over 3g connection
3g connection would kill the batt fast but then again if you think about it. if you are going to pay for it everymonth you might as well use it. or else the money is just going to waste. sometimes i am hesitant when turning off my 3g becuase when i start surfing again i always forget to turn it back on
no phone calls since i made the thread. just playing around with the cube for about an hour and a half. backlight setting at 15 seconds. still no internal GPS usage. had a few probelms with the cube last night so i played with it a lot. got it right now. did not charge it last night. today no texts sent and no calls. just checked the time every now and then. sitting at 25%. still havent charged it since sunday. obviously its now thursday. and others are reporting even if they dont use the phone the battery gets drained alot. did i luck up and just get a great phone? i'll keep a running log of what i do starting now. granted it wont be a scientific test but i will just keep track of what i do with th phone.

HSDPA is amazing, get around 500-750 Kbps connection !
It's "3G" plus some.
Hi all, searched and couldn't find what I was exactly looking for.
when i first got the phone, the battery life was short but since a couple of weeks ago, it's gotten much, much worse. i've had the phone for maybe a month or so.
i'm talking about the battery draining 10% in 30-40 minutes on standby with nothing like bluetooth or wifi on. at least the phone used to hold a charge decently if it was on standby, now it drains like i'm using it even on standby.
what are the greatest factors that affect battery life? when i first got the rom i have now, it wasn't this bad so i don't think it's the rom itself. plus i absolutely hate changing roms (it takes hours to get all my settings back)
some things i thought of:
i could use g-light but i noticed this makes my memory use quite higher and this doesn't do anything for when it's on standby anyway.
how often the accelerometer checks for rotation, right now it was at every 200 millisecond. I've changed it to 750 now, i'll see what effect this has.
same thing for light sensor. right now it's at 500 ms now.
radio. but again it was fine at first with this 1.09.25.23 radio.
anything else?
With my original 900 mAh battery the consumption was about 15% every hour. This was with the data connection always on. Without this on, it would last 2 days at least.
I also loose quite a bit of power when I'm in a bad phone reception area.
But not knowing where the battery consumption is being used up can be very annoying.
Whenever I'm abroad (and thus have all data connections disabled with NODATA) I always get a massive boost to battery life so it could be some process sending/receiving loads of data that you're unaware of? To test that you could install NODATA and kill all the data connections temporarily to see if that helps? Not that that would narrow down what was happening completely but it might help point you in the right direction.
i also suspect it might have something to do with data. what i've noticed is that my emails don't download fully, only the titles download and i think it stays connected while it's 'stuck' trying to download the rest of the messages, i notice this because it says in the menu 'stop send/receive' meaning it's still trying to send/receive. normally, i have it set to check every half hour. but i guess now it's always connected to data... anyone know why it's doing this? (maybe i need to start a new thread as i can't find an answer for this email send/receive problem by searching...)
kill the 3G chip that works for me but be sure the the provider has a GSM network
yup, 3g is turned off. these days the usage is more like 5% used up every hour in standby with email checked every 30 minutes. i guess that's acceptable...
Hi there. Ive had my Nexus One for nearly a month. I barely use it but ive noticed that the battery goes down EXTREMELY fast. Looking at it right now, it says it has been unplugged for 13 hours, 11minutes, 54 seconds with 28% of battery left. Earlier today I was at 4 hours something with 48% left.
It says Cell Standby is using 35%, Phone Idle using 33%. Thats 68% of my battery and all my phone really does it sit on the desk next to me.
Why is it like this? Also, how can i make it last longer?
Thanks for all the help
Sounds like you are in a spotty coverage area. That explains why the Cell Standby is using so much battery trying to hang on to the 3G connection.
How many bars do you have? and which N1 model is it? TMO or AT&T?
Also do you use wifi?
Hi there Thanks for the reply . I actually turned my 3G off, and now just running on a 2G conection. I thought maybe it was trying to connect to 3G heaps and that was chomping through my battery. With my 2g connection right now I have full connection. Im pretty sure with 3G I was the same, maybe 1 or 2 less.
I do use Wifi, however I turned that off. Also, I live in New Zealand not America so I dont have AT&T - Not sure what TMO is.
He's referring to the version of the Nexus that you have. AT&T or T-mobile, and is a reference to the frequencies that are used, not the actual company,
Ahh ok Thanks. 900/2100 UMTS
I think you are confused about those numbers, those numbers are the amount of battery each item takes up. So Your cell standby takes up 38% of each instant your battery is running. It did not take 38% of your battery. Wifi is significatly better on battery then 2g or 3g, i would advise always use wifi when you can.
Are you using exchange push? 2.2 has a bug that if you are not rooted on a new rom can create this rapid battery drain on exchange.
I recommend getting os monitor and seeing what is taking up the load.

This sounds really similar to what was happening to me the first week with my N1. Cell Stand by was my biggest battery killer. A few posts above has it correct.
Ironically, by turning off wifi in an attempt to save battery I caused my phone to use the cell antenna which uses more power, and takes longer to complete each task. I now leave wifi on whenever I am near my routers, and even most of the time when I am not.
Turning off live wallpapers and disabling auto updates on social networking apps can also be a big help.
Run a few 24 hour tests changing some of those factors, but generally, think about wifi as a battery saver and you should get a bit better results. Your not using exchange right?
Yep. Wifi should be a priority over network connection. Make sure you also change the wifi sleep policy to "never" (settings > wireless & networks > wifi settings > hit menu button > advanced > wifi sleep policy > never).
Also I would double check the APN settings to make sure you are using the best/latest settings for your carrier. (settings > wireless & networks > mobile networks > access point names) Make sure the one selected matches the recommended settings for your carrier (you need to call your carrier or google the settings).
Other than that, maybe a reboot would help? pull and reinsert battery?
Hope that helps.
Ok Thanks for all the replies. I dont have any push notifications set to automatically update and I dont use any social networking apps. Ill turn Wi-Fi on now and even though I set it to "never" sleep - it still does when I lock the screen...but thats another problem .
Im not using any exchange push, not even sure what that is.
Cheers
Yes keep WiFi on will save you an enormous amount of battery, no question. The difference is huge for me. And your WiFi sleep policy should be set to never. If you have the bug where this setting does not work, then that stinks and you could install the new driver that fixes it. But for now you would need to be rooted until the fix is official.
I have now enabled Wi-Fi and put 3G back on. However my battery is still draining fast. It now says my Wi-Fi is using up 30+% of my battery. Im losing about 8-10% of battery every hour - Im pretty sure that isnt normal?
The other place to check is: settings->applications->running services.
See if there is something in there that you don't think should be running. Your display should be using the most battery, so it sounds like something is running automatically.

i have a similar problem with my battery i see that your on fido network like me whats the apn setting your using?
@adambenjamin: Thanks had a look. Everything that is running I want running, nothing that shouldnt be there.
@d.brown: Whats a fido network? I live in New Zealand, your flag is showing Canada - so we arent on the same network?
@everyone: So just a little update/recap. Basically my battery gets drained quite fast. Basically all my phone does is sit on the table next to me. I might send 5 or less texts a day, thats it - That will be all I do with my phone. I DONT have any push updates, no social networking. I have my brightness down to the lowest it can go.
I am on 3G, have set Wi-Fi to "never" sleep (However it does anyway).
Right now my phone has been unplugged from being charged for 8hours 24 minutes with only 45% of the battery left - I have sent two texts today and thats the ONLY time I have used my phone. My display is using 31%, Cell Standby 27% and phone idle 24% = 82%
Something I have changed recently is going from one network to another. The network I was one of the two biggest in my country (Which means it has alot of towers). I changed to another network which has been going for just over a year (Less towers). Could my battery be running down faster than normal because its harder to find a signal than before?
Also, my signal strength is -107dBm 4 asu (Absoloutley no idea what that means, but might be valuable to somebody out there who can help)
Thanks for all the help
Switch to GSM Auto (PRL) instead of WCDMA Auto. this helped battery life immensely for me. i can get to around 20 hours of moderate use usually
edit: to do this, you'll have to make a shortcut to the "phone info" activity using anycut or bettercut or another shortcut app.
once in "Phone Info", there's a drop down where you can select gsm auto (prl)
Dunno if it was mentioned, get OSMonitor (free from market) and see if Email.apk is stuck at full cpu load. It's been a problem since 2.1, it does that sometimes. If it's at more than 10%, kill it and re-launch it.
Hmm well strangley my Battery seems to be alot better now. Been on for 1day, 15hours, 23minutes and its on 73% remaining. Before it would last like 15 at most and be out. All I did was Turn W-Fi back on. Thanks everybody for there help
Been having the same issues as you, it's kinda getting annoying now.
I'm pretty much the same as you. I'll send a couple of texts a day or so, then put the phone to sleep and leave it for a couple of hours etc. No continuous usage.
From say, 8am till 9pm, I'm left with under 20% left, after EXTREMELY light usage. Sending a couple of texts and turning the screen on to check the time a few times shouldn't even be considered usage at all!
I'm just a bit envious of others who claim 2-3 days with light net browsing, a few texts etc. Thats more than me, yet they use less power.
On top of that, I'm running CM6 which includes an undervolted kernel a.k.a less power usage....ummm?
I've tried everything!
1) I've underclocked to max 384mhz when the screen is off (960 max when screen is on)
2) Wifi is usually left on
3) Data is usually turned off
4) No rogue apps detected
^
At the end of each day I check "Spare Parts" in my battery history to try and find an app that is using an abnormal amount of battery...Everythings fine.
5) Under "running services" all there is are my widget services (none data-related. eg Set Cpu widget, battery widget, Fancy Widget)
6) The screen is on auto brightness
7) Sync is off
8) GSM Auto is set instead of WCDMA preferred.
Everything!
I'm pretty much limiting the use of the phone just to make it through the day on standby.
And please, don't accuse me of someone complaining about their 12 hours, 32 minutes of "light usage" (6 hours web browsing, sync turned on, 4 hours of Angry Birds,constant calling/emailing)
I used to be able to leave my phone overnight for 8-9 hours and only have the battery go down 5-6 percent. Now its triple or more. And frustrating.
I really can't think of anything else.
From my experience, when I was running CM6 RC1, I was getting about 2 day's battery life with pershoots (pre-720p) 2.35 uv oc kernal. After upgrading to RC2, I no longer got good battery life, and I tried everything I know of with little luck.
I decided to try a new ROM and kernel. Now I am using Geo's frf91 stock deodexed blackbar v6.1 with the Stock kernel. This is now my favorite ROM/kernel combination. Try that one out and see how you run at stock levels, then maybe flash a new kernel if you want. Pershot, and Wildmonk are the local favorites, but I found them to leave me with sporadic overheating/ touch screen or reboot to X screen glitches. I would try a few days away from CM, to at least isolate some variables.
What version of CM6 are you running?
Anyone notice a change in their battery life in the past few days? My girlfriend and I both are going through our batteries in just over half a day with no use. It's like the phone isn't sleeping. Looking at battery use Display is using all of the battery. I'm running CM7.0.3 and she's on stock. Looking at mine right now the phone has been on battery for 1 hour 34 minutes, and Display is taking 57% of the battery and I'm down to 84% battery.
Yes! I've had my N1 since January 2010. I stayed stock until recently when I installed CM 7.1 RC1 shortly after it was released. Battery life had always been great, both stock and under CM7, especially with SS4N1. Then, a few days ago it just fell off a cliff. I now get only about 7-8 hours, even with little to no usage. Before I'd barely lose anything if the phone wasn't being used (a percent every couple hours).
Now the Nexus One Battery Calibrator application shows a drain of ~200 mA or more constantly.
I've been tearing my hair out for the last few days, uninstalling apps right and left, trying in vain to figure out what's causing this. I even considered a full wipe and reinstall of CM 7, thinking that some system setting somewhere had gotten horked.
I've always had WiFi set to never sleep, since I'm usually either at work or home. I've also had preferred network type (*#*#4636#*#* -> Phone Info) set to "GSM auto (PRL)" for months.
I've not made any other changes I can think of that would've had such a drastic impact on power consumption. I didn't track all the app updates that happened around the time it started, so I suppose it could be one of those. But I've uninstalled just about everything and it's still happening.
I have the same issue! Just in the past week or so. I have about 50% battery then a hour or so later it's dead! I was going to get a new battery today but maybe it's a CM7 issue. I use the nightly as soon as they hit the mirror.
An update on this... There may be a big issue going on with T-Mobile or some recent update:
http://www.tmonews.com/2011/07/t-mobile-g2-users-suddenly-suffering-from-huge-battery-loss/
Looks like other users on different phones have the same issue!
Thanks for that article, Lost Dog. Makes me feel a bit better. At least I know I'm not just going nuts.
My phone still has increased battery drain even if I put it in airplane mode though. It helps, but it's still much faster than before. This makes me really puzzled as to what the cause could be. How could the cell network still be causing increased drain if the phone's completely disconnected from it? Some sort of configuration information it received that persists even after the cell radio is turned off? EDIT: I may be wrong on this one, see below.
Last night I tried a complete wipe (using Temasek's full format "Format-signed.zip" first), and re-installed CM7.1 RC1 completely fresh. I installed only the minimal Google applications and a couple crucial tools (my password safe app). However, I'm still getting the same quick battery drain today.
I hope we (or T-Moblie) can figure out how to fix this. It really cripples my phone as a useful tool to have such short life!
EDIT: I'm going to try a workaround I've seen mentioned in comments on the TMoNews and Phandroid articles about this: limiting the cellular connection to 2G/EDGE only. It seems to have made a significant difference so far. I may have been incorrect then about airplane mode not having an impact. I'd only been checking current drain with the N1 Battery Calibrator app, and never left it in airplane mode for long. Anyway, I'll post back later this afternoon with results.
Ok, so switching to 2G-only for the cellular connection seems to have made a HUGE difference. The drain rate seems to be back at around what I'd expect. Everything else I left exactly the same (WiFi on, GPS enabled, same applications, etc.)
So, I'm starting to suspect something may be up with T-Mobile's 3G/3G+ service in some areas that's preventing phones from idling properly.
Anyone else want to give it a try?
Interesting, I'll switch over to 2G only and see how that affects my phone.
I've gone as far as wiping everything and that didn't help so if it really is a t-mobile issue then that would shed some light on the situation.
I see the same trend when switching to 2G only. Very steep power usage with 3G then a dramatic decrease in the discharge slope in 2G.
T-Mobile has an issue. The trick will be getting someone there to listen.
Sent from my Nexus One using XDA App
Here is my screenshot. You can clearly see when I turned on 3G. Dramatic difference. Looking on the T-Mobile forum there are many people seeing the same issue but there's mostly finger pointing and speculation as to the cause.

I also got the same rapid battery drain since last Wednesday. At that time, I thought there may be a hardware/battery issue for my nexus one. To test this, I switched my rom from CM7 back to GB stock. After a few updates for the GB stock and used it for a day, same battery drain happened. So, I changed to use another backup battery yesterday. It did not help also. I thought it may be a real hardware issue.
Then, I found this thread and research a bit in the web. I found out it could be either caused by tmobile or google map updates. I first uninstall google map and reinstall the new version right from the market again. I also switch off 3G as well. No rapid battery drain for the entire day. The battery runs normally. When I came back home today, I turned on 3G, let it for a couple of hours, checked a couple of emails and received a 20min phone call. Everything seems to work fine. No noticeable rapid battery drain was observed. My conclusion so far is: this is caused by google map 5.8 update.
Try to uninstall it and reinstall the google map from the market to see if it helps.
Good luck.

Well, I'm willing to give it a try, but I'm skeptical. If it were the Maps 5.8 application that was preventing the phone from idling correctly, or transmitting tons of data, wouldn't we expect it to happen regardless of whether the phone was using the 2G or 3G radio connection? Sure, there might be a slight difference in the drain rate, but we'd still expect to see it in both cases. And yet the accelerated drain is alleviated completely by using only 2G. I have the Maps 5.8 application and can fix the problem by using 2G only. That indicates to me it's not an issue with the application.
I'll try uninstalling Maps tomorrow (I'm using CyanogenMod, so it's possible to remove it completely). Then I'll put the phone back on 3G and report back on what happens.
I've been experiencing similar battery issues the past week or so too. It looks like turning on 2G only seems to fix it, but what I don't get is why I'm still getting horrible battery life?
I have tasker auto turn off my 3G all together whenever my screen is turned off, and yet I leave my phone on my desk untouched all day and I end up at 40% when I get off work.
Wouldn't turning off 3G via Tasker be the same (or close to it) as turning on 2G only in the settings?
Hope t-mobile gets this worked out pretty soon!!
Glad I saw this thread. My wife and I both have N1s and have each been noticing unusually fast battery drain just in the last 3-4 days.
Last night I charged both phones to the same percentage, turned off 3G on hers and let them both sleep for a while. The phones are configured pretty similarly (stock, latest Maps installed, similar push settings etc). After about an hour and a half, my phone had lost 11% of its charge and hers had only lost 2%. That's enough of a delta for me to point to the 3G usage as the culprit. I guess I will be leaving my phone on 2G when I'm not using it if I am going to be away from a charger for a while.
It's NOT the Google Maps update.
Well, I did my experiment yesterday to rule out the Google Maps 5.8 update as the cause of this issue.
I'm running CyanogenMod so it's possible for me to uninstall Google Maps completely, not just the updates. I did so on Saturday night. Still set to 2G only, I removed my phone from the charger Sunday morning. A few hours later I enabled 3G. Later that afternoon I turned 3G off again.
I think the screenshot speaks for itself. Again, this is without Google Maps installed at all.
I asked around this weekend, and my friend's wife (also here in Portland, OR) is experiencing the same issue on her G1 on T-Mobile. Reading online I've heard about the problem affecting the MyTouch 3G, the G2, and many here with the Nexus One. The common elements seem to be: T-Mobile 3G service, particular models of phones, and some particular geographic areas.
Bottom line (IMHO): T-Mobile has a problem with the configuration of their 3G service in some areas, and it's preventing many phones from being able to idle/sleep properly, resulting in huge battery drain.
Here's mine, I posted this several days ago in the TMONEWS thread.

That's interesting. Even locking the phone to 2G/EDGE didn't have an impact? (not a Nexus One there it appears, what model?)
How did you go about disabling the 3G connection? I'm not sure if there are multiple ways to do it, but I used:
Settings -> Wireless Networks -> Mobile Networks -> Use only 2G networks
Really strange that even pulling the SIM didn't seem to make a difference. Or maybe that's not the same as turning off the cell radio entirely? Perhaps the issue is lower-level, like the radio constantly polling the tower or something even in the absence of being able to successfully register on the network for active use.
Does enabling airplane mode fix the drain issue for you?

This is a G2.
2G has been much better than 3g, but still probably only 3/4 of my former battery life, optimistically. I checked "Use 2g networks only", same as everyone else. The graph above is a little misleading, since I really saw better battery life, that initial flat and quick drop actually averages out to "decent", rather than "horrific.
At the "Pulled SIM and SD card" mark I re-enabled 3g, so the drain afterwards is still 3g related.
Pulling the SIM doesn't disconnect it from the radio tower, you can still make emergency calls/etc. so it has to maintain a connection I suppose.
Twice I hard-reset the phone, pulled out SD and SIM, and still had huge huge battery drain. Powertutor said IDLE draw was 1437mw on average, no SIM, no WIFI, just sitting there on my desk.
In Airplane mode it'll last for days...

I'm not familiar with Tasker. However, maybe it's just disabling cellular data use, not actually disabling the 3G radio? From what we've seen it appears the problem is very low-level, perhaps something to do with basic communication/negotiation between the cell radio in the phone and the towers, as there's no indication of particular application activity or significant data transmission that the Android OS is aware of.
In the T-Mobile support thread there are reports that T-Mobile is now acknowledging there's an issue with changes to their HSPA+ network in some areas.
I've had 3G off all day and my battery life is back to normal. I'm at 87% after at least 6 hours on battery. Yesterday I was down to less than 50% by this time. Luckily, I am able to be on Wifi at work so I don't have to deal with EDGE speeds, which make the Baby Jesus cry.
deliamber, you probably noticed this already but I'm also in the Portland market. It's gotta be a network issue.
I'm having the same issue on my N1 (I'm around the Portland area myself)
I did everything as well, 2g is the only thing that saves me..
Can't wait for a fix!
Picked up my phone yesterday afternoon and after receiving the OTA and factory resetting afterwards, my battery life has been fantastic on the first initial charge. My screen on time is at 6+ hours and still going.
I haven't done anything special. My phone is bone stock with only T Mobile bloat disabled.
Is anyone else getting ridiculous screen on time?
Is this just leaving the screen on and not doing anything?
No...Just my regular usage on a lazy Sunday night while in bed.
I'm on wifi.. with Wifi calling on, web browsing watching videos on youtube, a couple phone calls and heavy texting. Also have 3 gmail account with push notification.
Stats look funny with the cell standby on top of my usage. Usually it's the screen that's on top
I've been really impressed with the battery on this device. It's been more than enough to get me through an entire work day. The fast charge feature is great for a quick top off before a night out.
I don't think this is out of the ordinary, I think the question was standby + SOT. It's easier to get high SOT times if there is no standby associated. So 6hrs SOT while the phone has been off the charger for 7hrs isn't as big of a deal as 6hrs SOT + being off the charger for over 24hrs.
That Cell Standby too, damn...that's caused by having VoLTE and WiFi Calling on. Agree with what everyone else said, 6hrs SOT with the phone being on for 7hrs41min is not really a proper measure of your battery.

The real question is...why is cell standby the highest battery user if you've been on wifi with wifi-calling? this is what makes no sense.
I am able to last a full work day just streaming satellite radio and always on and off it throughout the day and still have a lot of a room to spare. Pleasantly suprised with how great the battery life is. Short of watching video's I am still at 30% range come night time. My S4 would of bottomed out at some point in the afternoon. I have to train myself to not have this phone plugged in every outlet I can lol.
That screen-on time.....
I get 4 hours max....... With whiped cache, VoLTE off, wi-fi scanning off, and wi-fi calling off.
Spotify and maps both slaughter the battery, but still.
Wifi/VoLTE calling
Yeah I've noticed that when on WiFi calling (with or without VoLTE enabled) phone never shuts down the radio. As in, I actually see both the signal strength indicator (crappy at my office) and WiFi calling, which never happened on my Lg G3 -- as soon as it goes on WiFi calling it'd turn off regular radio.
I bet that's the reason for big cell standby energy consumption.
Did anyone else notice this?

Whipe your cache and disable wifi-calling and volte. The radio won't consume so much battery afterwards.

Um... no. Without WiFi calling phone is useless. I was asking if anyone else had WiFi calling on and NO cell signal indicator at the same time

i get the wifi calling and no signal type indicator (IE 4g, LTE, etc) but i do get signal bars. This is exactly how it functioned on my g3 as well though with the lollipop update. If you want no bars showing, you have to change your wifi calling prefs to "never use cellar network"

Yeah my G3 before lollipop would simply remove the cellular indicator after about a second on the WiFi calling. I wonder if it's something that just changed in the system.
It's really annoying as previous behavior was exactly the logical one -- found WiFi, WiFi calling kicks in, regular radio gets turned off in a bit (hence no bars any more), if you go outside of WiFi coverage it turns back cell radio. Signal is so crappy at the office
Hopefully they'll fix it. I guess for now I have to keep switching "no cell at all, WiFi only" and back to "ok, cell but no WiFi calling". Ick.
I got 3 hours sot with 53% left to go. I have to say i am getting close to my note4 on this. I am very impressed so far.
Mine is doing well today. This is with Spotify and Snapchat usage.
Mine is getting better
So WiFi calling and volte on?
Yes to volte I don't use WiFi calling
I have airplane mode on, wifi calling, while I'm at home. Saves the most battery.
