Battery life in the last few days

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!

[Q]Heavy battery drain when on WiFi

Hello everyone, there are many, many threads for our phone, so it is basically impossible to properly search and see if this question has been asked before and so here it goes.
I've tried many roms for my device (I call it Sir Hangsalot), and I have noticed that on almost every rom there is a huge issue for my device to keep itself in a deep sleep state when the WiFi is on. The ratio is approximately 70/30% awake vs. deep sleep (I am talking when the screen is off and the phone is not being used). Then I have tested with the WiFi off (mobile data still on, it is always on since I have an unlimited data plan) and the phone enters deep sleep as usual, but this time it stays in deep sleep and battery is discharging properly. From the moment I switch on the WiFi the same behaviour emerges again. This is the last night's situation. New battery (1 month old, 1700 mAh), fully charged at 1 AM, at 7 AM 54% left with the WiFi on. The night before, same conditions, WiFi off and mobile data on, at 7 AM 91% left.
So, my question is: what the hell is wrong with our WiFi which is causing this huge battery drain and is there a fix (rom, kernel, module, script, anything)?
Regards.

Sorry for late reply.
Go to Settings > Wifi > Advanced settings and uncheck the box "Network notification" ( Notify me when an open network is available) in wifi settings, also uncheck "Scanning always available" .
Use Greenify app to freeze apps ( apps frozen will stay closed until you open them again).
These should reduce battery draining.

Thanks for the reply. I always turn off those things in wifi advanced settings, and regarding greenify I am not sure that it will help since I have this issue in every rom, even in a barebone rom without installing any app or gapps. I thought that maybe google play services could be the culprit here, but even without gapps I have a severe battery drain when wifi is on. When using mobile data everything is just fine. I really cannot find an answer for this.

Stock jb bloated should also drain much battery when there is a network connection.
I don't have more ideas... But why you keep wifi on overnight? Do you have facebook app/ what'sapp / viber / etc. ? These drain battery alot, that's why you need to greenify them.
And why you use wifi since you have unlimited data plan?
To be honest, my battery drain too when i have wifi on, but not so much. In this evening, i will put my wifi on and i will let you know how much battery i have left tomorrow.

It will be interesting to see your results, thanks. I do indeed have WhatsApp installed (after setting up my device completely) but the behaviour is the same regardless, even after fresh install and no other than the core system apps (stock, cm 10, 11, 12, aosp, carbon, vanir, LS, tried them all). Regarding leaving wifi on all the time it is the matter of habit. Since I've been using an android phone from the start (from cupcake on Huawei U8220 to lollipop on a few devices) and I have never had this kind of problem. Oh, well, I will try to keep it off and turn it on only when I need faster internet speed (my data plan is unlimited but it does not have download speed as my wifi).
Cheers!

I tested two days. Wifi drain battery 15-20% for me. Hmm, maybe i have some wakelocks, not sure. I will check and i will let you know if i can solve this problem.

[Q] Wifi is off but shown as on

Anyone came across the situation that the system suddenly show wifi is on inside battery page but is actually off and I haven't turn it on manually?
It seems to be on inside the battery page sometime in the midnight but I double checked the wifi page it is off, and I am sure I have turned it off before I went to sleep.
And yes I have checked previous posts and my situation is:
1) as seen from the battery page, wifi use turned to positive some time in the midnight when I haven't touched it, and kept on until I notice it.
2) confirmed unchecked scanning always available, also wifi on during sleep turned to charging only and I was actually not charging last night
3) I habitually turn off wifi by default and only manually turn on wifi. The wifi page also shows the wifi is off
4) the wifi bar on battery page goes away after reboot, without me changing any setting. And I want to know if there is any other way to do it.
5) battery usage seems to drop like wifi is really on, i.e. quicker than when it is off.
So the problem is, how do I know if wifi is really on, when battery page say it is and wifi page say it isn't? And what possibly triggered this irregularity?

I discovered that bug months ago, also related with a high battery drain with Google Play Services.
Sometimes is there, sometimes it's not; haven't found a workaround.

Yes you helped me earlier with the Google play services in another posts. Now I have upgraded to the stock 5.1.1 and basically the google play services now stabilized (in a sense that it drains me battery but not as harsh as before ). So I think my current case may not be related to google play services. I just don't understand why different pages can show different wifi status, particularly when it started during a night time when no one has toggled it.

Mobile Radio Active being the main reason of discharge

Hello, I bought my Oneplus 3T recently and I'm using stick ROMwith ElementalX. The main problem I found is that everytime I look at what consumed the highest percentage of my battery are things like WA, Google Play Services, etc. If I click on the to see what is happening, I always get the Mobile Radio Active working like pretty much all the time.
For example, in a normal use for me which is between 26-30 hours until I decide to charge my phone(between 10-20%), I get a SoT of 4 hours and a half more or less. The problem is that from the total percentage of battery used, these applications which have the Mobile Radio Active problem drain between 10-15% of the total amount of battery, while my screen is like 7% of that total value.
Researching on XDA, I couldn't get any solution to this problem. I call this a problem because, every day I see new photos from people with between 7-9 h of SoT in maybe 20 hours of use. Of course, you can't really call this a bad performance of my phone but I think that this difference of hours with screen on is greater than the amount of time my phone stays with my screen off.
As a consequence, I wanted to know if there is a solution or some tips to reduce that Mobile Radio Active bug in order to extend the time between charges.
Thnk you very much.
Additional information: I cleaned flash stock today + ElementalX kernel + SuperSu to see if this kind of bug dissappears.

To "solve" the Mobile Radio Active bug you must take some extreme steps:
First, Root your device. This MUST be SuperSu unfortunately, as the app I'm going to suggest doesn't allow you to toggle the required settings with Magisk or Phh.
Install LeanDroid.
In settings, allow disabling of Wifi, Cellular Data, Bluetooth, Network Location and GPS Location.
Set to "0 min" after screen off. Click "Except".
Configure this screen to your taste, but I have "Except if tethering", "Except if charging (AC). Under Wifi I have "Except if connected to <my home WIFI>" and I have "Except if active: Limit" set to 100KB/s.
Bluetooth "Except if connected"
Location "Except if GPS in use"
and "Network Mode except if original strength OK."
Go back to the main panel.
Restore "After Screen Unlocked"
"Every 60 MIN after screen off" (Configure this to your liking)
With SuperSU and the above, turning the phone screen off disables the data modem when the transfer rate is low, this effectively shuts down the radio and prevents the Mobile Radio Active bug.
Run this with tools like Greenify and ForceDoze to really pump your battery life.
It's not unusual for me to see 8 hour screen on time with these apps and the above configuration.

and without root?

Just curious, how is the status of this bug ? I followed that Bug for like 1.5Years...since Lollipop i think. I myself tryed several things in Sultans ROMs in a OnePlusOne, but no Solution so far ;-(

Bug is still active. As far as I can tell, it remains active in Oero too.
The only option if you are not rooted is to close all apps and toggle airplane mode before you switch the screen off. This only solves the issue until the next time data is accessed by any app, though

THX for reply. Jepp on Wifi i get 4-5days @3-4h SOT. On Mobile only 2 days

Obviously, it takes more power to send/receive signals to a cell tower 10 miles away, versus a WiFi router that is 20 feet away.

Also using WiFi doesn't ensure the modem is Switched off. Modem power doesn't mean data.

This this bugs even remain active in Oreo i will never use android again.

It's existed since Lollipop and I doubt Google will fix it any time soon.

To get 7 hours of on screen time, you will of course have to sacrifice something, the laws of physics are always with us, reminding us from day to day things that can and can't be done. But hey, if you live in a cardboard box next to a cell tower should give you much better battery time without sacrificing the phone-part of your smart device. ? ?

Abnormal battery consumption in wifi

Hi, I'm noticing an abnormal battery consumption when the phone is connected in wifi (about 7-10% per hour in standby) and I can see the lower arrow of data connection always on, so some apps are constantly download data. I have tried to close several apps manually (even system app) but nothing has changed. In 4G instead all is fine. Do you have any idea what the problem might be?

I did notice this, too in the newest firmware.
Did even check if there is much traffic (can see it per app in adguard), but nothing.
Workaround for me is to disable wifi if in standby.
(Doesn't help if in usage of cause...)

What apps are showing at the top in battery usage?
Have you thought of installing BBS, there is a version that runs on non-root.
Does RCSService show up in battery usage?

Just in case it might help our op:
After 1day 12 hours (35min SOT):
Standby 11%
Mobile net in standby (sorry need to translate it) 6%
Deezer 6%
AdGuard 4%
Android OS 4%
Android-System 2 %
Bluetooth 1%
Display 1%
--> This should make 35%, but well, the phone shows 60% left, so still 5% are missing (I suppose it's just "other" apps >1%).
Phone still showing 2 days 4 hours to go.

I can see: Google Play services, RCS, Google Play Store, Android Operating System, Chrome, Wifi, Memory.
For installing BBS, for what I could read, you need to install via adb and for now I don't do it.
However, if I reboot the phone when I see this strange behavior, keeping always wifi on, then the phone returns to normal operation, and the battery consumption is normal. The problem starts when I turn on the wifi manually, with the phone already switched on.

Hi,
i have this problem too (not rooted, last firmware).
About 6% / hour if connect the xz1c to wifi.
If i simply restart the phone (with wifi on), it decreases to less than 1% / hour.
Did someone find the cause or a solution?
Thank you.

I opened discussions in Sony Mobile forums:
International
Italian
If you want, write about your issue there.
Maybe it will help to be solved.
Thank you.

Same problem here. I replied in the RCS thread, but on the latest 2 firmwares I lose about 7%/hr (idle drain) with wifi on and less than 1%/hr with wifi off. My phone also gets hot when I keep wifi on while idle. I've solved the problem by keeping wifi off except during large downloads, and I have a high enough data cap for that to be a reasonable option. Still annoying though.

Has anyone checked if there is a difference when WiFi scanning is disabled?

Good day.
I do not currently own a xz1C, but in my Galaxy S8 had the same issue, until i turned off "WiFi scanning" like user 'pseudonym58' said.

I have WIFI scanning OFF.

Hi, I'm noticing an abnormal battery consumption when the phone is connected in wifi (about 7-10% per hour in standby) and I can see the lower arrow of data connection always on, so some apps are constantly download data. I have tried to close several apps manually (even system app) but nothing has changed. In 4G instead all is fine. Do you have any idea what the problem might be?

Hi guys,
yesterday i tried to see if Play Store in XZ1C was updated.
(play store, setting, tap on version)
It wasn't.
Tapping on version, it downloaded last version (8.9.24)
I rebooted the phone.
Battery drain on Wifi seems reduced (with my two modems) or maybe solved.
I'm monitoring the situation and i'll let you know.

Strangely it's 2 or 3 days the problem seems gone, I don't know if the reason for the change is the updating of some app or service. Play Store has been updated yesterday but the problem was already gone before. For now all is ok.

@aerofan
What version is installed now on your device?
(Btw I can press the version 100 times, it always tells me it downloading a new version )

I have 8.9.24.
This is what i did:
I tapped on version.
It said "google play will be updated" (or something similar)
I waited for a while (no notifications or messages appeared)
I came back on google play and tapped on version and it said it was updated.
I rebooted the phone.

Strange, I had an older version installed but it would not update.
I uninstalled all updates for the playstore and searched again: 8.9.24
Edit: Didn't fix the battery consume

I am experiencing the same issue. I have not checked on the google playstore version yet.
As soon as I switch wify on my battery loss is about 5-6% an hour when doing nothing. There is also no program standing out in the battery menu. When adding the consumption times there is a huge gap that cannot be explained. RCS phone shows up, but only with minor usage.
I will be back to you after checking the version of google playstore. Hopefully it does the trick.
Edit: I disabled automatic updates of google playstore and rebooted the phone. Battery consumption looks normal now. I then switched on auto update again. It still looks good.
Edit: Battery drain can temporarily be fixed with rebooting the device. Updating the playstore or disabling automatic updates did not work for me. Any other ideas?

Hi,
I have same problem with my battery life, it's quite fitfully.
I've checked that my battery can stand 3 days and 7h of screen on, but on the other hand sometimes my battery only can stand 1 days and 2'5h of screen on.
I make a very undemanding and very similar daily use of the XZ1 Compact
I have my xz1 Compact totally updated: Firmware v.47.1.A.12.119 PlayStore v.9.4.18 and disabled all of uncommon scannings (Wi-Fi,BT,Location,etc..)
My router has 2.4ghz band only enabled and WPA-PSK security, during the night I specially have good and strong Wi-Fi signal in XZ1 Compact.
So...Does anyone know what may be happening? I really appreciate your help.
Thanks.

Wifi battery drain was improved on the past few firmwares for me, but it's now back with a vengeance. This is on 47.1.A.12.235 (July patch). Absolutely massive drain during the times when wifi was on, with almost no screen use during that time. I resorted to turning wifi off.

The 5Ghz band uses a lot of juice, maybe the latest firmware pushes the phone to use that frequency by default. To test this try seperating the 5Ghz and 2.4Ghz frequencies on your home router and joining the 2.4 with your phone.
This is just a hunch on my part, but I can't back it up with any proof.
