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.

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!
Hello,
I subscripted to a data plan with my carrier and I was wondering what is the best way to handle this situation to remain always online.
I have wifi and 3g on so when I'm home or in a place where wifi is available it connects to that network and disable mobile data and opposite when I go outside wifi coverage.
But I noticed two major problems
- I went out for 30 minutes, the phone switched to 3g and the battery went down 7% without turning the display on! I walked and the coverage is extremely good where I went plus I noticed that the wifi icon was still on so it wasn't really disabled
- When I came back the phone didn't go back to wifi connection and kept staying in 3g until I open wifi settings manually. This is a bug with cm7 I already reported!
Those things don't happen always but they do happen. Does 3g in "idle" consume so much battery power?? If yes The phone would die in 8h without even using it if I used it according to this rate it would die in 3h
My guess is that some of the phones may have some hardware issues, because the software is identical, but only a small part of them drain the battery when using 3G.
I have a similar issue: http://forum.xda-developers.com/showthread.php?t=1501047
edit: my Froyo drain was normal, 1% per hour, vs GB (stock, CM7, etc) which takes 5% per h. This would be an argument against a hardware defect...
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.
My cell standby is really really high and I'm nowhere near the 6+ hours SoT that people seem to be getting here. I even followed the battery optimization guide and disable all the moto features on the phone. I also changed my preferred network type from "Global" to "LTE/CDMA" to supposedly save more power.
Is anyone else having odd drain? I attached a list of the apps I disabled as well.
Cell stand bye does seem high. Silly but I'm sure you have turned phone off and fully charged to see if it remedies?
All else fails factory reset, I know it's a pain.

I charged it while it was on fully after draining it to 1% when I first bought it. I have not turned it off or charged while it was off. I'll do that later when it is around 5% after work.
How would the factory reset help? I would reinstall the same apps again anyway so if that is the problem I wouldn't know it.
I didnt mess with any network settings but cell standby is higher than screen on my battery stats. My battery life isn't bad by any means but not as good as some others are getting
I've seen this issue reported by 2-3 other users, it's either related to the cell coverage in your area or might even be a faulty radio. Cell standby is usually high on my list but still about 1/4 of the power draw of my screen (assuming my average SoT of 6 hours) and around -96dBm (3-4 bars) signal strength. Try checking your signal strength - if you don't have an app for it, do: Settings > Wireless and Networks > More > Mobile Networks > Network type and strength.
I have this issue. My signal sucks at home. Only 3 bars most of the time.

Same issue here ... Just switched to ART and I'm going to switch from global to LTE/CDMA to see if I can knock it down a bit. Reception at my work is terrible in some spots (hospital). At home its not so bad.

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?

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.
