Motorola Droid :: GPS - BT - Wifi Battery Drain When Not In Use
Feb 15, 2010
Just to clarify, is there in fact battery pull and drain from BT, Wifi and GPS even if you are not actually using them as there no app running needing them and no icon showing them active in the menu bar?
I am curious if they are sending out polling or searching signals and thus, still draw the battery down? It seem they must, agreed?
Is it a substantial pull? I kind of want to leave them all on, but have started the habit of having them off and just using a widget to turn each on - 1 by 1 - as needed.. but that is kind of a PITA and I wonder if it is not even necessary?

I think I figured out why sometimes my Droid stays on for 1.5 days and sometimes after 6 hour of just being idle the battery is drained.
When wifi is turned on an connected to a network, the cellular signal is way low and it just drains the battery.

Rooted Droid 1, running LFY 1.9 with it's 1ghz kernel, SPRecovery. Had a weird issue recently; the phone displayed that my battery life was at 40%, then probably ~30 minutes later it was down to 20%. I wasn't using it during that time, I just unlocked the screen to check something. Anyway, I opened my browser and within a minute or two I got the "15% battery life remaining" message, prompting me to connect my charger. I decided I would allow the phone to just die and shut itself down. So I waited ~45 minutes and it went down to 10%, then almost immediately to 5%. I turned on the GPS just to make it drain faster... I watched a one-hour television show and when it was over, I glanced over to the phone to see if it had died - nope, still on. I turned the LED light on, leaving the GPS running for ~25 minutes and it finally powered down. Then I plugged it in to charge and left the room. Came back in about 2.5 hours later and picked up the phone - it was very hot. Unlocked the screen and checked SetCPU and it was running ~135?F but it immediately started cooling down. It was fully charged, however so I unplugged it. I went to bed shortly thereafter and the battery life displayed 90% as I set the alarm to wake me up the next morning. I happened to wake up shortly before the alarm was set to go off and I picked up the phone to disable the alarm and noticed the red 'charge me' light blinking - unlocked the screen to see 5% and just then it powered itself down.
TL;DR -- Phone only got hot that one time, phone hasn't gone dead in stand-by mode again like it did that night. Battery drains at a seemingly normal rate based on my regular use from 100% down to 40%, then it rapidly drains after that, always skipping 30% and when it gets down to 5% it stays alive for quite a long time under heavy load. Is there a way to 'teach' the phone how to check and calculate actual and remaining battery % and to display it correctly? Is it kernel-related? I heard somewhere about doing a 'battery wipe' but I am unsure what that entails and searches are proving fruitless for me so far.

At home i've noticed that even though I have wifi on, it'll drain 15-20% of my battery over night (8 hours). When I turn the display on it'll show that there's no wifi connection available, but wifi is still enabled. After i turn the display on, it'll quickly connect to my wifi. Is this normal? How do i make it stay connected to my home wifi when the display is off/phone is in standby?

Will toggling Wi-Fi on and off drain your battery? I'm asking this because I read:
[URL]...
Essentially, you want your Wi-Fi sleep policy to be "Never" because when the Wi-Fi sleep policy is "Always," your phone searches for Wi-Fi more often and that drains battery (I think that's what it is saying).
At the moment, I toggle the W-Fi on every time I'm using it and off as soon as I'm done using it in an attempt to save battery. I'm not sure if this actually works or it's actually draining my battery because it would search for Wi-Fi every time I toggle it on.
On my Samsung Galaxy S4, I can't find Wi-Fi sleep policy as mentioned in the article, but I found "Keep Wi-Fi on during sleep." Am I supposed to set this setting as "Always" to save battery life?
I toggle Air View and Smart Gestures on a frequent basis as well--not sure if I should do that too.

I was wondering, if I set wifi off but I keep the global sync option on in the 4.2.2 tiles, does the apps will try to sync even if wifi is off, and then drain a little bit off battery ?

I know the WiFi uses less battery than the 3G. My question is should I leave the WiFi on all the time if I only have WiFi at home? Will it be actively searching for a WiFi signal when I am out of range of my home network and drain more battery? I have the Network notification unchecked in the WiFi settings if that helps at all. Basically I just want to know if I should turn WiFi off when I leave my house.

However I wonder if it is less of a battery drain to use my WiFi at home / work than to simply use the Sprint network / Ev-Do Rev A?
I figured that since it can read my WiFi easier, it might use less power, then again it is a function on the phone that needs to be launched and therefore might be draining more.

What is your take on the WiFi sleep policy. I do like the fact that Wi-Fi can remain on all the time, but will it be a drain on my battery? Is it better to keep the Wi-Fi to sleep on screen shut off? I am near a Wi-Fi connection for most of the day and always at home.

When I ran it, my phone had been unplugged for about 12 hours and I found that Spare Parts showed my phone to have been Running (not sleeping) for 100% of that time. After being methodical and getting data points after opening various programs, I determined that after I opened any program that accessed the GPS, the phone no longer would go into sleep mode. To get the phone to start sleeping again, all I have to do is toggle GPS off and then back on again. It's completely reproducible every time on my phone.
Now, I don't know what kind of effect this will have on battery life, but seems like it probably would have some effect. If others can test this and see if it affect you at all, it'd be helpful to see if there's a potential major software bug here or if it's just something with my phone.
Easiest way to test is to start with a fresh reboot with GPS toggle on, install Spare Parts, plug in the phone for a second (to reset the counters), let it sit sleeping for a few minutes, then read the Running % in Spare Parts. Should be pretty low. Plug in the phone to reset the counters again. Then start Google Maps or any other program that will activate your GPS. Close that program and then let the phone sit idle for a few minutes. Check Spare Parts running time again and, for me, it's pegged at 100%. It stays like that until I toggle the GPS off or reboot the phone.

So I've noticed since I've gotten my phone that even when its plugged in (100 percent battery to start) if I use navigation for 45 min or so the battery will drain to around 80 percent. I don't understand how its doing this if its plugged in and the battery has the charging icon on there.

Okay so I woke up this morning and took my phone off the charger and headed to work. About 2 hours later I feel this burning sensation in my pocket and I put out my phone and this thing is burning up and the batter is down to 30%. I turn it off take out the battery, and turn it back on 10 min. later and attempt to charge the phone. I check about 15 min. later and the battery has drained to 20%. Any idea whats going on?

I just bought the extended battery for my Droid X yesterday and put it on charge for three hours last night and then at bedtime. I got up this morning with a "charged" battery. I used the phone a little today but not alot. By 7 pm CST my battery was at 30%. Is this normal, I mean with the regular battery I had a better battery life span than this. Did i not charge it correctly?

Since updating google maps last Friday, my GPS icon goes on all the time and my battery seems to drain faster. I cannot shut it off except to cycle the power on my phone. Anyone else notice this?

So my church is a cell-phone black hole.No 3G and barely 1x.They changed the password on the WiFi recently so until someone leaks it to me, my phone is near useless in the building. This stinks as I spent a considerable amount of time there over probably 4 days a week, so stinks to be me.That said, I've noticed that on days I spent a lot of time at church, my battery life is poor. Last Sunday however, I noticed my Droid/battery was HOT when I left church and by the time I got home, it was down below 20% battery life. Was full when I awoke (media dock) so this all happened in just a few hours, most of which it was unused.I returned that evening for some children's events and it dropped again to 20% in just another 2 hours in the building.

I've had an ongoing struggle with my X's battery life, from day 1 with 2 different standard batteries to try until now with the extended battery.
I've tried it all and thensome and nothing has majorly improved my battery life. I won't go into number of hours I get or usage details or anything, but I have a question I cannot seem to find any solution to.
I noticed after I updated to leaked 2.2 Froyo that very often the 3g up and download arrows are both lit up and basically never turn off. After a few days of trying to figure out what it was (and using Juice Defender in the meantime to shut data off except for 15 min intervals), I think I've figured out what is causing the 3g data to often constantly be transmitting.
I went into the Battery History screen, left it set to "Since last unplugged" and went to "Network usage". In here, the bar for "UID 10012" is very high, almost all blue. Every time I exit the menu and go back into to re-check those data numbers, they are always increased after only seconds while the 3g data symbol is active.
Inside of the details for that are several built-in system app names. I tried stopping a few of these through the Applications menu of the phone where you can stop services/apps.
I finally have force stopped one (has worked several times now) that has stopped the 3g data instantly every time.
This one is "Social Messaging Service".
Every time I click the "Force stop" button within that app's info page in the Application settings of the phone, the 3g data arrows stop lighting up instantly.
Is this app related only to the Social Networking built-in app (which I don't use/need)? Is it tied to other things? Is there a downside to me stopping this?
I can't seem to keep it stopped and it seems to cause this 3g data issue every day at some time (multiple times usually - seems to happen again a few hours after I've stopped it). I think it is attributing to my sometimes bad battery life.
How can I stop this ongoing Social Messaging "bug" battery drain?

Do the adds in free apps drain your battery? How do they work. Are they always connected to online? Well, i dont have any problems with the apps on my phone because they dont even show up. Does that drain my battery even more? I have a rooted phone and in all my apps that have ads only show some white circle showing that something is loading but no ads show. My battery only lasts 8-12 hours of use. And it sucks.

I loaded bb v1.0 with the 1.0 ghz kernel pete has on my friends droid. It is the same setup on mine. His battery was dead within 3 hourss. I noticed his sync icon is in the notifcation panel however it is not spinning. I think the calender is trying to sync and there fore is draining the battery. I deselected the auto sync option but the sync icon is still in the notification panel. Any suggestions what is going on or how to remove the sync icon. I rebooted and killed apps via task manager with negatives results.

I'm running NexBeast ESE81 OC'd to 1100mhz (Running idle around 23c). I've had no issues whatsoever and, in fact, have been on this ROM since the day it was released (a record for me). However, this morning my phone was fully charged and sitting on my desk when it suddenly dropped to 5% charge. I panicked, rebooted the phone, and it now says 70% charged. What could have caused this? I searched and found someone had a similar issue but no one seemed to know a fix. My phone is running fine now, but I want to avoid further issues.

My droid x signal pretty much always between -92dBm and -87dBm with 1-3 3g bars. My former droid eris would get -92dBm with 1 bar and also drain incredibly fast.
On the droid x, if I go into google maps, the circle of the cell tower appears and the place I live at is half way within the edge of the circle and the other half is outside of the circle. I always seem to be connected to this tower. Bad luck I guess that I'm on the outskirts of the circle.
Does anyone know how cell towers are distributed? Do they overlap sometimes?
I run pandora with the screen off for a half hour with the screen off and my battery is down to 70%. I have about 15% screen brightness and battery saving mode on.
yesterday, I was on meebo for an hour and 45 minutes and it was down to 60% from a full charge.

Motorola Milestone user here. I posted this yesterday in the appropriate section, but I figured this issue might apply to other phones as well. Sorry for the lenght but I thought I'd cover all bases.Anyway here's what happens when I charge my phone overnight. Let's say my battery is at 80%:
1. Turn off Wifi
2. All tasks killed except for Alarm Clock. Sometimes I run the Music Player but it doesn't make a difference with the battery drain issue whether I use it or not.
3. Background data is not enabled
4. The "Stay Awake" (Screen will never sleep while charging) option in the "Applications" menu is NOT CHECKED
5. Auto-brightness is not selected, and brightness is set at the lowest level.
6. Data Roaming (connect to data services when roaming) is not selected
7. Bluetooth not on
8. Charge the phone - I see the animated lightning bolt icon
9. Press the "sleep" button for the screen, or, allow it to naturally go dark after 30s

My battery seems to be draining about 1/3-1/2 faster than it normally does over the past week or so. I'm trying to figure out if it has something to do with any apps I've installed recently. Is there a way I can figure out which apps are doing the most damage to the battery?

My Eris is always getting stuck on the screen with the 3 skateboarding droid dudes. Here's the story of what happened and what i have done so far. I have an unrooted Droid Eris, OS 2.1 OTA been working quite well for the past few months now few weeks ago, my battery was suddenly drained for no apparent reason (it was idle), no programs were running in the back at all it went back to normal after i turned it off and charged it. It happened again to day and when i tried to turn it back on, i got stuck on the 3 skateboarding droids. So i tried battery pull, x123121 didn't work. i did the "hold vol+send+power", -recovery: it gives me this red triangle with exclamation point, i only found errors regarding this on rooted phones while on this screen, i pressed vol up+power, and tried all the option there and nothing worked, it still gets stuck on the skateboarding droids then i held the "vol+send+power" and tried all the other options there, and it stuck on same screen.

My Eris, just updated on Monday for the lock up from sleep Anyway, I am a low user of the phone and keep, wifi, Mobile data off unless I am using it I have noticed the last 2 days the battery life is improved. yesterday, phone on at 6am off at 11pm, 65% left, no data used, few Txt messages and about 45 min of phone calls Today so far, on at 6am, WIFI, Mobile data off, one 6min call and one txt, at 9am, still 100% battery. turned Mobile Data on at 9am now it is 11:50am and battery is still 100% my on time is 5:45, awake time is 8 min (2%) this is typical for me. I don't have email set to push, I refresh when I want it. I also use Advanced Task Manager. So maybe the issue that was fixed was also causing a battery drain and is fixed now?
