Android :: Power Saver Modes For Android (battery Life)
Jun 30, 2009
Here are the settings I am trying out as my "Power Saver Mode" for my HTC Magic (Rogers). Not sure yet how much of a difference this whole set up will actually make, but I'll try to make it a scientific study. Please take a look, I am interested in comments on the setup in general, and on individual settings (ie. will a particular setting really make that much of a difference to the over-all power usage?).As of the moment I changed all these settings, my battery is at 97% (After I turned on my phone this morning, all these settings were previously opposite so i could get my email, etc).
1. Screen Brightness 15%
2. WiFi = OFF
3. GPS = OFF
4. Auto-sync = OFF
5. "Enable always on mobile" = OFF
6. Background Data Usage = OFF
7. Use only 2G Networks = YES
I am also using these apps:
"TasKiller" to kill BG apps
"Useful Switchers" to modify settings.
It would be nice if there were an app that could work like the power setup in the system tray of Windows where you can choose different power modes for your laptop. A simple app with a Power Saver Mode, Balanced Mode, and Power User Mode that could all be set by the user.It would be nice to be able to run the app, choose the "Power Saver" mode and have it automatically change all the settings as I've listed them above, and then be able to choose "Power User" to reverse them easily so I don't have to go through all the separate steps to do it myself.

Does power saver just change the data connection stuff, or does it have any affect on performance?

Found a good way to save on battery life. Use airplane mode app to switch off all communications on your Wildfire at night. I had to download an app called StudioKUMA Airplane Scheduler. I have set mine to 11:00pm off and back on at 06:00am so should save a load on battery power.

How to disable the baked-in power saver feature in some Samsung Android phones? the one that dims the screen, turns off the keyboard backlight, and doesn't let you use the camera once you hit 15%(or 10%) battery left? can't stand that, for my own needs anyway!
i figure it might be an edit to the kernel source code, or something like that. i just don't know where to do that. I know it can be done tho, because i remember having some ROMs on the Epic 4G that had that junk disabled. guess i'll also see if some of those old devs. are still around.

I'm thinking of getting the HTC desire when it releases in the US and I know it has already in Europe. I'm one of those people that would use the phone for internet, texting,probably not emailing.I'm interesting in what you guys' batter life is.Like if you had 3g off and all those battery saving tips.Like manual switching 3g on when needed etc.Since I want an accurate time to go by because I'm going to do the exact thing when I get mine.Using battery saving tips for max.As well if any hardcore power saving iphone users can post their times as well since I can't find anything on the web relating to that.

This just popped up my on my twitter. Y5 Battery Saver Keeps Wi-Fi On Only Near Trusted Spot. When you connect to wifi, it'll remember the rough location (without GPS). Periodically it'll tap back into that location and if you are near it it'll flip on WiFi so you can connect. If you aren't near an area you've connected too before, it'll keep wifi off.

This might be a dumb question, but does powering the phone on and off shorten the life of the phone? I power it off completely every night and then power it back on the next morning to save some battery. I've always done this with my other phones and never had a problem, but this being a smart phone with so many applications running, it's like a computer so I wasn't sure if it's just better to leave it in sleep mode all night instead.

I was on the MobileDefense site and they said that having your GPS on really doesn't use any energy unless you have apps that are actually using them.I've had my GPS off this whole time thinking it would suck up my battery power running in the background.Can anyone shed some light on this subject?

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?)

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.

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....

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 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?
