Hope this hasn't been asked already, but here goes. When I had my G1 occasionally i would find a few apps running in the background needlessly, and would close them down. With the Nexus One every time i check, there is at least 15-20 apps running that dont need to be. Is there a way to minimize this to conserve battery?

I will create a service to do something when some hot situation occurs.
By hot situation I mean:
the GPS/cell coordinates are in known zone;
known Bluetooth device detected;
known Wi-Fi network detected;
weather info has change;
considerable movement speed change detected: eg. from walking to travel by car.
As you see these tasks are heavy, and will be run frequently. 15 mins, but sometimes even more, when I have to detect the movement speed of the device.
The question I have, will this drain the battery heavily?
If so, what recommendations do you have to minimize battery drain with the above tasks?
Android doc say:"When the system, rather than the user, shuts down an activity to conserve memory, ... "
But how to simulate this situation?I want to debug the onRestoreInstanceState method,but don't know how to.
My .mail folder contains a bunch of files I can't identify what they are or what they are used for. I have moved ALL THE FILES AND TOKENS to a temp directory and my Here seems to be working fine with the .mail folder empty. I think these files have something to do with email I receive and delete. Has anyone ever cleared out this directory to conserve storage space? Are these useless files and can be deleted?

On the default keyboard for the HTC Hero there is a button that minimizes the keyboard. Is this not an option at all with the Vlingo keyboard or am I just missing it?
View 4 Replies View RelatedHow can I minimize the stuttering of my graphics?I am using MANY ImageView's in my program (and JUST ImageView's). I change their positions directly, when I need to change them without using "onDraw" to redraw everything. Is it ok, If I do not overwrite onDraw? I have in average 10 objects which I added to the mainscreen-layout.These 10 objects are 5 trees and 5 flowers. The trees and flowers have 5 different states and therefore 5 different ImageViews which I all added to the layout, whose just are invisible. So I have about 50 ImageViews added to my main screen When one of these objects changes its state, I just make its ImageView invisible and the ImageView of the new state visible.Is it ok to do it like that?I realized that if I just use one ImageView for every object and change the ressource of it when its state changes, all objects, which are currently added to the mainscreen-layout, change their position to (0;0). That was the reason, I have so many ImageView's added to the mainscreen-layout.Is there a better solution for that?

I can see in LogCat that the video is buffering during the lag. Is there a way I can minimize this lag, or tell MediaPlayer to play the video sooner?
View 1 Replies View RelatedI just signed up for these forums because soon I will be an HTC Desire owner in Canada. Having never owned a smartphone before I do have a few questions. The plan I intend on signing up for is the Telus Student 40 and that will come with only 100mb of data. Now I don't see myself being too data using heavy so I feel like I will be able to live with it. However I do have some questions regarding my data consumption.
1. Is it possible to completely stop all data usage by somehow disabling the data connection if I find myself reaching my limit?
2. What are ways to track my data usage to make sure I don't use too much data?
3. What are good ways to conserve data usage? I'm getting the feeling that there are some applications that will constantly be sending data back and forth updating themselves, is it possible to have these applications but stop them from constantly updating and only have them update when I want to access the application?.........
I've flashed with the new froyo ROM with senseUI and am finding it brill. One quirk though is that when typing out a text message, there's no key in the bottom left to minimize/esc from the keyboard. If I use the Back key it exits the app (chomp). It's still beta!)
View 6 Replies View RelatedWhat I'd like to be able to do is:
if I'm connected to a specific wifi AP (my prepaid hotspot),
1) turn off autoupdates from the Google Play app
2) turn off data for all apps except the foreground app
3) or let me decided which apps I want to allow to transfer data when connecting via that hotspot
This is to minimize costs associated with using that prepaid hotspot, but the same concept could apply for people who have limited data bandwidth per month.I'm using Android 4.1 on a Samsung S3 if it matters.

Often I'll be busy browsing or writing a message or whatever and I'll be interrupted by the full-screen incoming call display.
I'm looking for something that automatically puts incoming calls in the background, ideally just in the notification bar or something without interrupting the current app.
It's particularly annoying when I'm writing a message in Opera for example and an incoming call wipes the message because Opera doesn't have a proper restore state.
I don't want to block calls all together, just make them less intrusive.
I found a program called backgrounder, but it didn't seem to work, and from the youtube video I saw of it, a full screen still appears to pop up on an incoming call.
I know I saw this somewhere, but couldn't find it. Anybody have a zip or some sort of file to get the keyboard back from 1.5 onto the 2.1 ROMs? Not having the button to minimize/hide the keyboard is bugging me and I hate the swipe to hide.
View 4 Replies View RelatedSo the "minimize keyboard" button in the lower left of the landscape qwerty keyboard works maybe every 5th time. I only started noticing this after the 2.1 OTA. However my wife has the 2.1 on her Eris as well and hers works perfectly. If I make sure to push the very top edge of the button, it works fine, but just pressing it normally in the middle rarely works. Perhaps there is something wrong with that corner if the screen.
View 6 Replies View RelatedSo I'm using NexBeast v1.1 on my Droid and noticed in the clock app there is a brightness button that dims the screen even further (similar to the bedside app I'm guessing). Unfortunately the screen dimness only lasts while in that app. I was wondering: is there a way to set the overall phone brightness itself that low or keep the screen that dim outside of the app? The lowest brightness in the Droid settings is still a bit too bright for me.
View 5 Replies View RelatedAnyone know what could be the cause of my battery dying while I'm asleep at night? I don't put it on the charger at night if the battery is above 20% and the last couple nights my battery will be near 30% and when I wake up in the morning it's dead?!

View 3 Replies View RelatedJust got my Nexus One yesterday, and I'm loving it! My only concern is the battery life meter is telling CELL STANDBY 67%?? When you click on it, it says time without signal 50% and then it says thats whats causing battery consumption.
Before I go on, I have no issues with 3G, been getting a solid signal since I got the phone yesterday, just a little confused on what to do? Shouldn't standby SAVE battery?
Anyone else have this happen? This morning my phone battery started draining really fast and the phone was hot. After a couple hours, battery was drained, I checked the system to see what was the drain and it showed facebook took out 89% of the battery. I'm not even using facebook. How do i get it to stop?
View 6 Replies View RelatedJust switched over to a Nexus One from my iPhone 3GS (been an iPhone faithful since they came out,but wanted to see what was happening with Android).I love my Nexus One, but the battery life is horrible.From a full charge, hours later, I'll be at 75% having barely used the phone at all. If I leave it for a day, it's almost dead entirely.I've gone through settings, turned off the automatic syncs, don't have push turned on, brightness is down, location is off,wifi is off.can't figure out what's going on.Sometimes when I pick the phone up after leaving it for a while, it feels warm, as if it's doing something.I've re-started many times,I have a task manager, and I kill every task often.still, awful battery.For what it's worth, the phone takes forever to charge as well. It charges about 10% every hour.Seems like something is wrong, no?
View 19 Replies View RelatedI hope you can help me out by chiming in on this. I've been using my phone a bit, and it looks like my battery goes down by about 10-12% for every 15 minutes I'm on a call. Is this normal? It seems like my battery isn't lasting anywhere near as long as it should. Extrapolating those figures out, you'd be looking at 150 minutes (2h 30m) of call time per charge - way below the quoted time (7h on 3G). Additionally, I seem to be able to lose about 10% of my battery just browsing the web for 10 minutes over 3G. I have GPS off, but WiFi and sync on.Are you all getting significantly better than this?

View 5 Replies View RelatedI have a very big problem, as my Nexus One is draining heavily. My Nexus One drains 1% every 4 minutes, no matter which ROM I install Sense, AOKP ICS, MIUI (ICS) and even Stock. The battery remains the same, I have tried various options: from calibrating the battery, wiping battery stats to purchasing a new battery. Neither of those options worked out. The battery still remains the same. My guess is that it's a hardware error.I have no guarantee, as my bootloader is unlocked and I opened the phone once.
View 2 Replies View RelatedMy specific device is a GSM Galaxy Nexus.
So, I have 3 batteries for my phone. 1 stock (1750mAh) and 2 extended (2000mAh). No I don't need all that juice... its a story for another time. Anyway....
Lately when I charge a battery in the external charger (using a USB cable and the wall plug supplied with the phone) the battery will not fully charge. The LED on the charger will change from red to green (Usually I charge the battery overnight, or while I'm away at work during the day). However when I put the battery in the phone, it will show somewhere between 80%-90% charged.
1) Would a 100% drain and charge reset the battery's "fuel gauge"?
2) My phone automatically powers off at 6% (which is fine, needs enough juice to save current settings and power down properly). Is there a way to truely drain the battery down to 0%? (I'm thinking of some kind of low-voltage lightbulb or LED connected to the positive and negative terminals should drain that down to 0%. Is this recommeneded or is it fine just running it down till the phone powers off?
Normally I try to plug my phone in and charge (or power off and swap batteries) once they hit about 40%-60%. I'm only interested in doing a full drain to see if that will get these batteries to fully charge in the desktop charger. Besides I've read from a few sources that it is GOOD for the battery to do this once in a while (Fully drain, charge to100%) to properly maintain them.
And as a side note, charging the battery in the phone (either with the wall plug or from USB cable on my computer) will always result in a 100% charge, which makes me thing the issue is with the desktop unit itself (perhaps faulty circuit that cuts off charge current when it thinks its full ?)
I'm having problem with my Nexus 7. I have Android 4.2.1 on it. I've been using it for about a week now and every night i would turn it off, but in the last few nights, i decided to leave it on sleep mode to see how the battery life was.
On the google site, it says that the Nexus 7 should have 300 hours of standby. Is that the same as 300 hours of sleep? Because when I left my Nexus 7 on overnight, it drained from 55% to 33% in about 8 hours. That doesnt seem like 300 hours to me.
Also, I've tested it again, started at 100%, no wifi, no gps, no apps running in background, no syncing, in sleep mode, and it's draining at about 2% and hour. I've read on this forum that people have been getting like 2% every 8 hours on sleep, or even overnight. I've never used 4.1.1 so I dont have anything to compare it too. Does the 300 hour standby time mean powered off Nexus?
2 days ago, a drop or 2 of water got into my USB connector of my nexus 5, and i didnt notice and unfortunately plugged it in to charge it. Suddenly, i heard crackling sound and started smelling smoke/burning silicon/rubber.
I quickly unplugged it, but it was too late and it could no longer charge. however, later at night, i tried cleaning the formed rust off the connector with a thin piece of metal, and now its charging properly, but it is a bit sensitive (aka moving the usb cable will stop it from charging)
however, i started noticing that my battery is dying really quickly, i mean approximately 1% every 2 or 3 minutes when im just browsing the net or even just arranging my homescreen icons.
The top back of the phone (near the camera area) is also getting hotter than usual when only doing the above mentioned things, and the temp decreses at the bottom part/battery of the phone. so im guessing its the cpu thats heating up (top)
however, i was talking to a google rep about a replacement before i got the phone to charge, and she made me factory reset it before i send it to them (but ended up not sending it because theyll charge me because theyll find out its water damage), and i dont know whether the problem is because of the burnt connector (thats functional now...) or because of the reset. I reset it a second time, but the batter/cpu temp is the same.
in battery stats, Android system is in 2nd place the whole time. Screen is about 40% and andoroid system is about 15% (with a CPU total and Keep Awake of 12min)
So does the damage of the connector have to do with the battery/cpu heating up? like could it have affected them? because my battery was normal before the factory reset/usb damage.
how to disable the low battery alert audio? I have disabled the popup, but I would like to also disable the audio. I tried deleting the lowbattery.ogg file in the root media file, but then it just played a different audio file for the low battery. I am on a rooted Nexus 5 running 4.4.2
