No Signal = Battery Eater!

Noticed a severe problem on my Desire!
I went on a camping trip yesterday, and just got back a few hours ago.
And my battery life has been terrible!

I had 99% battery, put the phone to sleep in my pocket, and 2 hours later, I had 86%!! I never touched the phone! and I use governors for the phone to be at 122-307mhz ..
another 2 hours, and then it dropped from 86% to 74%!
I noticed both times the phone had no signal, as I was up in the mountains... It must have been the battery eater!
So the phone dropped from 99% to 74% in 4 hours on standby! After that, I decided to put the phone on hibernate..
Previously, if I left the phone on standby with signal at home, it could get me 8-9 hours before it drops from 100%-99%!
Phone is currently charging. Bit disappointed!
(Note: in my graph, it shows I had GPS on, but I only used it for 5 minutes, when it was at 100% to drop to 99%. I also had ALL data connections off, apart from the phone on)
Anyone have similiar expierences?

Low signal is a battery eater on all phones. If you have no signal, it has to search for a signal source more often, I certainly have this on my Desire S too.

Agreed. If I know that I am in a no-signal area and I really need to preserve battery, I either put the phone in airplane mode or switch it off completely.

latest radios sux big time if we speak about signal.. phone lose and search signal very often..and u can see some times 1 some times full signal bar and sometime no bars at all.

Thanks for the replies guys
I'm currently on the radio from the OTA .4 update...
Guess I'm now gonna upgrade to the .5 one, as that too has heavy drainage!
Cheers!

Aeroplane mode on all sense roms that i've tried on this device use about for times the battery that normal use does, air plane mode use =18mA compared to 5-8mA with phone and wifi on (these figures are obviously from a good reception phone area and connected to wifi with a strong signal, it's difficult to test in a bad reception signal area where I live)

If you know that you're going to be in a poor signal areas then it's a good idea to switch the phone so that it only receives 2g signals, add thus will reduce the about of polling that occurs and therefore reduce the waste in battery use
Obvious but daft, if going camping where's you know you'll have little to no signal then it probably pays to simply power down the phone when you're not going to use it

That's curious, thanks for the info.
Must admit, I've only used airplane mode briefly when I specifically needed to use some other function on the phone, so I guess I never noticed the extra consumption.
It sounds completely counter-intuitive that it used more power, but you have clearly got detailed information!
I can certainly say for sure though that switching the phone off completely extends battery life loads

*#*#4636#*#* > Phone information > Turn off radio

Oly I've noticed this problem too. I normally keep my phone in my pocket at all times.
While operating for fractures, we sometimes wear lead aprons to protect us from xray radiation which emanates from the image intensifier.
These are 0.5 mm sheets of lead which block out or attenuate all radiation...including phone signal!!!
I had noticed that if I go in with even 95% battery, by the end of 6 hrs my battery would come down to 10% to 13% without ANY use!!! So I started leaving the phone out on the table and no more battery drain...!
I'm on stock radio by the way. Heard bad things about the battery drain on the new one even with normal signal. I could be wrong...I'm just quoting the opinions of people who've used it.
So I guess in any situation where signal is poor the phone goes bonkers trying to scan for a stronger signal and kills the battery!!!

Oh yeah. Confirmed it does here. Playing with RCMix as of last night. Odd, I wonder how you get to testing mode now. I'll investigate.
To Oli: Can't remember if you use Tasker? If you don't remember to switch off 3G, set a profile to drop 3G when outside the radius of your town/city and signal strength drops below 'x' dB for 'y' minutes as long as screen is off. That'd work too.

http://en.wikipedia.org/wiki/GSM
"The transmission power in the handset is limited to a maximum of 2 watts in GSM850/900 and 1 watt in GSM1800/1900."
If the phone is trying to communicate with a base station and having to transmit at that kind of power to reach it (in poor signal areas) it's going to drain your battery pretty quickly...

I can confirm, I also work in an area with poor coverage and it normally ( with stock 2.3.3 rom) would come down from 100 to 10 % in about 8 hours on standby..
Now I have changed to Proxuser 2.3.5/Sense3.0 it has improved but still very unhappy with the lifetime though. I would like to have 3 days at least with moderate use.
Here is a screenshot of the 2.3.3 drainage.

Poor battery life on WiFi

Hi, can anyone help me solve this problem. I'm getting poor battery life from my Nexus S (stock 4.0.4) & android OS using a lot of battery. I've narrowed it down to WiFI - when I turn WiFi on, the battery depletes much faster than when I'm on 3G & android OS goes from ~7% to ~20% in battery stats. This is the opposite way around from what I would expect based on other posts, which say that WiFi uses less power than 3G. You can see the effect in the screenshot - for the entire time on this screenshot, I was at work with good 3G coverage & the WiFi point is right outside my office:

Any suggestions?

I agree with you, stock 4.0.4, Matr1x kernel (but I get same results with Air kernel too) and wifi always on = poor battery life.
My workaround is keeping it off and switching it on only just before an autosync or when opening browser/Gmail (I do that with Tasker)

When WiFi is in use what are you doing?

Essentially nothing. I checked the odd email, but for the most part the phone was in my pocket doing nothing.

have you got a background service that only runs on wifi?
also, in my experience, 3g only uses more battery when you're actually receiving data (e.g. browsing, data sync).
to me your battery stats don't look that bad, so my theory is that because you don't use your phone that much, anything that uses just a little bit of battery makes a big difference in battery use percentage.
but then again, I could be completely wrong...

Well one thign is for sure battery will always die faster on the network because most of the time if your in bad service areas it trys to fight for service therefore shi**ier battery life.
But @ Richstant do you disable mobile data manually like. For example because my NS4G is just deactivated on my Epic 4G i manually disable data and re enable when i use something so i save battery life.

I switched my sleep policy to while plugged in now. The difference with just switching the wifi on and off is really insane for me.

The way WiFi works while screen is off is hopeless on the Nexus S. I think it may be exagerrated because of the guzzling hardware as it seems no different on the GN or SGS3, though they dont drain nearly as much (i thought otherwise at first, unsure if it's on a phone-by-phone basis though). WiFi likes to stay on even if you set sleep policy otherwise - look at it funny and it will stay on and drain. This is something that i hope will improve in JB, but i doubt it. For now, best bet is set to Never (or plugged in, same effect) and switch it off manually if you won't be using it for long periods of time.
WiFi uses less power for large amounts of data and even browsing. It's faster, it doesn't need to send extra power and there is less thrashing to find the best signal. Data, however, is technically always there anyway as the radio is always powered, so if it only needs small amounts of constant data, it is often better for battery if you have good reception. This is one thing we i don't think we'll be worried about in newer phones, thankfully.

I'd forgotten about that setting, I'll try it now. In the past it's not worked for me though - the WiFi just stays on all the time no matter what.

Thanks for the info - sounds like it might be just the way this handset is :-( I don't remember it being this way under gingerbread, the WiFi turned off properly when it slept then, and battery life was much better.

I'd still disable the mobile data even regardless of how good the reception is it'll still save you more juice in the long end

You don't have any apps set to auto-upload or backup anything (e.g. Dropbox Camera Uploads, G+ Instant Upload) once it connects to Wifi do you?

Hmm, that option worked fine for me, when I unlock the phone, there's a 1-2 second delay before the wifi icon comes up, if I am not plugged in, that is.
I have latitude on all the time, I am suspecting that latitude is the one that causes my battery drain WHILE wifi is on, since there's just too much wifi hotspots around here, and if latitude is triggered everytime there's a new wifi hotspot discovered, then it will have a lot of updating to do. Using the sleep mode doesn't cut down the number of wakelocks (reported by BetteryBatteryStats) that those LocationServices triggers however, but battery life does seemed to be saved, especially on the days where I rarely use my phone.

I would look at this also. If there is an app that has some connection with wifi (i think this would be done through intents but i'm not very familiar), it may either keep wifi on or awaken it from sleep periodically (where it looks like other apps/features take over and continue using it instead of shutting it off immediately). Maps and something from Android OS or Android System seem to be main culprits if the battery page is to be believed. BetterBatteryStats can help, but haven't gained that much information in regard to wifi - though is priceless in most other areas.
Edit: Didn't see the last post (got distracted lol). That could be it. Note that in BBS you should also look at the number of wakeups, not just the time wakelocked. Obviously you can rack up a lot of wakeup attempts and still show only 1s of actual wakelock, but it adds up immensely from there - particularly when some other apps are triggered because they are notified wifi is temporarily "active" when it shouldn't be. Also, these are my experiences and not coding fact, so take them with a grain of salt and listen to those wiser than I

Well I'm pleased to say I got a serious improvement in battery life by setting wifi to off when not in use (except when charging). I tried that under 4.0.3 & it didn't work, but it seems to work correctly under 4.0.4.

wow, I didn't even know there was a "wifi on during sleep only when plugged in" option. I knew juice defender and other similar apps did something like that, but didn't know it was built into ICS (or CM9 )
thanked for the tip

[Q] Who's to blame for battery drain?

My phone went from 90% batt to 0% in 5h of screen off time. Usage shows Android OS 60% and SopCast 30%.
When i locked the phone i left it on the home screen.
So who's to blame? The rom, kernel or the app?

could you please provide a bit more detail like what kernel or rom you have and also if you could upload screenshot of battery usage

Rule out your application first. I'm assuming SopCast is a podcast application? If you were streaming, that will explain it. And yes. We need more details.

Well the same here lol. However if you focus a bit you'll find out some nice things. Kernel wake lock will give you the apps that keep your phone awake. For me its mostly the exchange which is email. You can take a screen shot and share if you'd like.

Anyway this is no longer related to that obscene 90% overnight bcuz i uninstalled sopcast. Now i just had 16% drain overnight (with Wi-Fi off) which is still a lot imo.

Having 18% drain overnight on JB with wi-fi off. Any ideas?

Why are turning wifi off in the first place? That is stupid if you're trying to extend battery life.
What is your cell signal like. A crappy cell signal drains battery. A crappy 3g signal that is constantly on because you turned off wifi drains even more.

i was under the impression (from gingerbread times) that wi-fi uses up more battery than 3g; this was among the tips you would find back then on android sites to extend battery life.
Anyway, i have yet to find out who is calling the AlarmManager that is keeping the device awake. Any idea how i would go about doing that?

I didn't mention that info so far because the initial problem of this post is fixed (SopCast (podcast app) keeping phone in stream mode) by uninstalling the said app.
Now, i believe that the overnight drain on my current JB ROM is too high.
So, here it is: Rom is Grean Bean ( http://forum.xda-developers.com/showthread.php?t=1821478 ), kernel is Matr1x 22.5 (but the drain didnt change when i changed kernel (beladus, _thalamus, air) and the significant mods that the rom has are V6 supercharged and brainmaster's twks.

That was not the case in GB times or any times. Either you read wrong or the sites are stupid. Considering that for the most part the android sites / bloggers are still idiots today, who knows.
Anyways. WiFi uses the least battery. Less the 3g/2g. Should be used whenever possible to save battery. Phone in active use or idle you should be connected to WiFi over cellular data. Turning all radios off but enabling WiFi is the most battery efficient thing you can do and still have data but you won't have the actual phone. I do that at my buddies house where I get no service at all. Not going to use the phone for a couple hrs use airplane mode. That uses very little power if the phone is sleep. Turning the phone off and on uses more.
Also the better your signal is the less power the phone will use. You still gave no signal strength info. Frankly you're wasting your time with better battery stats and wakelocks etc when you don't fully grasp this radio stuff. Use that tool when you need to find something that keeps your phone awake when idle/not in deep sleep.

That's the situation i'm in. It seems i've solved it by figuring out which apps were calling the AlarmManager and the Media server, there were 2 actually: Latitude and Google Music Sync, that were waking too often. Now i've simply disabled them.
I didn't give any signal strength info, bcuz i didn't move and didn't change the radio. It's a jelly bean thing for sure (i have google now disabled). Many users have been complaining (in various rom threads) about this new found drain after the upgrade.

Yeah, I normally play with a new ROM bare boned to see if has a natural drain.
Then I add the apps that I have been using that I know do not drain battery life.
And the other person is dead in with the signal advice. I had a HTC hero before and it had many tweaks on fixing the signal so battery would last. Which is why I love the pull down notification bar and some ROMs have idle timers.
Good luck

battery information

Hi guys, I am from Peru and I have the team this thread. I want you to know how much they long does the battery if you leave the 3g on with the screen off without using it, the reason is because my phone with the screen off and not much use to me lasting 9 hours and do not know why?

It depends on a lot of things. I think it should last longer than 9 hours with little use, but if you have things like FaceBook or newsfeeds or weather updating frequently, that could wear it down. If your 3G signal is weak, that could definitely wear it down.

thank you very much for the info, I think my battery is damaged. Today I leave with 71% battery in 3 hours and 50% battery low, only had 3g but because data was transferred to a prepaid chip. As I can see if my battery is damaged?

I usually last ~36 hours, data and screen off.

Did you check to see what is using up your battery in Settings? I can easily last for over 24 hours with the display off, or otherwise known as standby mode.

If your keeping it in your pocket and/or in an area where it is going in and out of signal, it will go through battery very quickly. Even spending a hour in a store where you get no signal. I have noticed a more poor signal in my pants pocket vs a shirt/coat pocket. It will show underneathe the battery graph as red under signal. I agree also that having a ton of apps syncing will eat battery on mobile data, also things like gps, bluetooth, wifi on with no connection, ect.
I normally lose about 25% during a 9 hour work day, with 4G on. But I don't run alot of apps that need syncing (all set to manual), only have google contacts syncing on, and I'm in a constant good signal area. That's with a few google searches, email checks, and forum checks.
Edit: I'm on CM10 with blue lightning, smartassV2 w/stock clocks.

Just curious... are you running CM10? I've noticed that even though my screen isn't on I was getting a ton of battery drain from the screen regardless of kernel used... so I went back to Tweaked.
Now I get a 1% loss per hour with WiFi & sync on and WiFi calling active when the screen is constantly off.

i read somewhere this battery works for Galaxy S Blaze
it's $20: http://www.amazon.com/QCell-Samsung-3850mAh-Extended-Battery/dp/B006SKHIKG
And seems to have more juice than the default battery.
Anyone try this one out? Results?

Just FYI, the user had a Galaxy Nexus GSM I9250 and Galaxy S Blaze and verified it worked. Hopefully the extended Nexus battery isn't bigger in size. Just double check the size of the Blaze's.
I'm starting to want to upgrade my battery haha, maybe when mine is grows weak.

hello friend. Now install the kernel, and I gave a charge to the battery, choose a governor but still the same battery is spent like water, I will upload a picture of what is consumed.
The battery was at 76% and I the consumer up to 73% and went to sleep, this was it consumed:

sounds like it's a weak battery. might need a new one.

Horrible battery drain on LTE

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

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

I dont have LTE with my provider but from what ive read this is normal.

As with many battery issues, you will probably hear vastly different experiences from different people. I've had LTE in my area the entire 1+ years I've had this phone (area had LTE since before the phone was released). I seem to have good coverage in the area, and can often get 48 hours (or a little more) on a single charge with light usage. Drain while idle on LTE for me does not seem significantly different then when in a non-LTE area, or on WiFi (around 2% per hour).
Its possible you were in a fringe LTE area, which would drain the battery much more quickly than an area with good reception. But I would not describe the type of drain you experienced as "normal". Or at least not what is intended or expected.
Since the phone is stock, there isn't a lot that can be done. The stock AT&T ROM is locked out from turning off LTE (which would be one workaround). Flashing a different ROM or radio might help. But those require root, bootloader unlock, etc.

I was in Baltimore, which has had a fairly mature AT&T LTE network for about a year, IIRC. I was in downtown most of the time, which shouldn't be a fringe area. At one point, I did a speed test, and got 17 mbps down and 9 mbps up. I know there's not much that I can do about disabling LTE using the stock ROM, but I shouldn't have to use a custom ROM; this type of drain shouldn't be happening.

I'm pretty sure you can switch LTE off on a stock ROM. Enter the following code on your dialer keypad:
*#*#4636#*#*
A menu will appear, select phone information.
Then scroll down and you'll find a drop-down menu. Open it and select gsm auto prl or wcmda preferred.

You can, but it won't stick, since AT&T has this setting 'locked'. It will reset itself to LTE on at the next reboot.

I'm just curious but did you have the Power Save turned on because when I use Power Save and I live exclusively in an LTE area it would last me about 48 hours on a single charge give or take a little. One thing you can consider is checking to see if you have applications running in the background trying to use your data even though you may have it turned off.

Power Saver was turned on. As far as apps running in the background. I try to stop that. I have auto-sync for all apps, except for my two Gmail accounts, turned off.

You mentioned you used the phone a bit more heavily but never mentioned screen on time. 8 hours doesn't seem all that bad to me if LTE + 3-4 hours screen on time.

Screen wasn't on that long. Take a look at the screenshot in my first post.
Also, in the meantime I've found an APN setting which is supposed to just use AT&Ts HSPA network and not LTE.

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

I haven't had any problems with it yet. A few hours with data on the past few days, and I haven't noticed it drop. I'll keep you posted how it works the next few days.
