Android :: Proximity Alert And Battery Life
Mar 4, 2009
I wrote a simple app that uses proximity alerts and after installing it on my G1 found that battery life have been halved at least. It's so bad that phone needs to be recharged mid-day or it completely dies by 9pm. There is no polling of any kind - just proximity alerts (3 of them). I tried with GPS turned off (using network triangulation for coarse GPS location) but battery life is still abysmal. Is there a general solution to improve battery life with proximity alerts or the whole GPS thing is a non-starter on G1s?

I am adding a proximity Alert with an expiration of -1 (does not expire). I am testing using an Evo. The proximity Alert fires several times after entering the location and staying inside the location. I was thinking that the proximity alert should fire once when you enter the location and fire once when you exit the location. Should the proximity alert fire multiple times after you enter the location and stay inside of the location?

i bought a mtk6577 clone s3. My problem is sometimes i rebooted phone, after opening proximity and light sensor doesn't work. screen don't turn off in call and doesn't call the person displayed on screen when i take ear. And battery drains too much. (example: when proximity and light sensor works with %90 battery, when it doesn't work after reboot plummets to %50).Another issue is when i reboot phone, boot animation doesn't show when proximity and light sensors don't work.

The internal meter says it is due for charge long before its out of juice. Battery Left widget will give accurate voltage levels, but it too is fooled, even after proper calibration.

Does anyone else find that their battery does best at like 60%-70% charged and when it gets below 40 it moves a lot quicker? Also I've done 3 full drain and full recharges so far and my battery has improved sloightly each time, do you reccomend I do it again or is that just bad for the battery?

Background info:
- I'm running the "Battery Left" widget and I have it displaying "estimated percentage left", "system percentage", and "estimated time left until dead".
- I listen to A LOT of Slacker Radio.
My issues:
- I was previously getting about 19+ hours out of a fully charged battery. 2-3 days ago I started having issues with the widget (I think it may have started when I installed an update to the widget) so I recalibrated it to no avail. Then I uninstalled it and reinstalled it. Within a few hours it claimed that it was getting accurate readings (when I first installed the widget weeks ago, it took days to get accurate) and now says that I should be getting 9 hours out of a fully charged battery. I know that can't be right so I'll see how the widget adjusts itself over the next few days, but, any thoughts? (I know a lot of you guys use the same widget and know how it works...)
- Also, In the first two hours of my phone being unplugged this morning, it went from 100% to 70%. I did run Slacker for about an hour and a half of that time, but could it really drain the battery that much that quickly? And I noticed that when I close Slacker, if I go into phone settings, applications, running services - there's still a Slacker update thing running in there. Could that be draining the battery too, even if it's only checking for updates?
- I really don't run a lot of stuff on this phone. I keep wifi and gps turned off. I use bluetooth only a few hours each night. Minimal web browsing. Although, my POP email gets checked every 5 mins (but I just changed it to every 10) and I do use gchat and text a decent amount, but I'd say overall, it's "light" use (except for Slacker which could be a huge drain, right?)

Does anyone know of a way to have the Droid make an alert sound of your choice when the battery is fully charged? It would be awesome to hear when the battery is charged rather than have to keep checking visually at various intervals. I can't keep my hands off of the phone so I can get a little impatient during the charging process sometimes, I'd love to be able to "set it and forget it" until I hear the alert. If there isn't a way to do this, someone should figure out a way to make it so.

My battery life was bad, but it was OK, but in the past few days my battery life is 10% per 30minutes(Just over 5 hours on a charge).I used to get 8-10 hours on a charge.I noticed last week that while it was charging the status of the battery was "Overheat".I think I somehow cooked the battery?I use TaskKiller and kill 95% of apps automatically, I have bluetooth,wireless,GPS disabled and the screen dimmed.I have not changed or installed any new apps.I have not changed the way I use the phone at all.My battery was dead, 0%, and it charged to 95% in about 45 minutes.Is this even possible?In fact in the past two days I have not gotten the charge above 95% at all.

I've been playing with my phone since the update to 2.1 and I suddenly noticed, by looking at the notification area, that my battery was getting critically low - but I hadn't had an alert, either onscreen (I don't think) or audible to tell me so Could I have switched it off accidentally, and if so, where can I switch it on again?

i have a G1 and i dont know if its just my phone or battery or what. But the life is terrible, i have everything off, no brightness, timeout to 30s, all the wifi/bluetooth/etc is off. Yet after about an hour of takign it off a full charge it drops to 70%, i can barely make it 4-5 hours in a day when its not even being used! Seeing that i want to upgrade anyway, so i can get the newer operating systems and better phone hardware, what phones right now have the best battery operating life? I hardly use the phone for its data features. I basically use the phone as a phone,a decent amount of txt messaging, ill use wifi here and there, and ill manually sync some calendar items. Im on T-mobile, whatre youre phone suggestions? Im trying to keep them at $300 or lower.

Does such a thing exist? I've only come across ones that show the remaining battery life as 10% increments and was looking for something more accurate/exact. My Evo had this ability, but my Droid X doesnt.

Is it just me or does the Hero with 2.1 seem to use a lot more battery that when it ran android 1.5?
And are there any tips/apps to help conserve battery power?

In reviewing this post http://stackoverflow.com/questions/2317428/android-i-want-to-shake-it, the highest rated answer says you should unregister and reregister the listener for the accelerometer onStop and onResume to conserve battery life.
My question is how do we know which listeners we need to stop/resume to minimize our applications footprint on battery life? Things like do OnClickListener, TextWatcher() etc - do they need to be changed?
and if anyone knows, what about adMob's SimpleAdListener?
I sort of assumed that the UI listeners don't consume battery if the Activity doesn't have focus. As for the SimpleAdListener I have no idea....

The phone pops up an alert when the battery is fully charged, saying to unplug. First of all, is there a reason for doing so? (Is it bad to keep it plugged in once it's fully charged?) Also, is there a way to disable this or at least make it quiet (without having to silence the entire phone), so it does not wake me up?

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
