Motorola Droid :: Battery Life Being Drained By Android OS
Apr 25, 2010
Any ideas why "Android OS" is taking up so much battery life? For the past three days my battery life has been much worse and when I look in the battery usuage its always showing "Android OS" to be the highest with a percent of something like 60%.It used to be the case that "Display" and "WiFi" were the main cause of drain but now they are hovering at just 10%.When I tap on Android OS it doesnt give me any extra details. Also when I browse through the "partial wake lock" usage on the battery left up it lists "Android System" with a 1/4 bar and all the other processes have no blue bar.Any ideas what part of Android OS is taking up the battery life? How would I be able to find out whats happening inside the "Android OS" process?

Since few weeks my battery life get drained by my screen. My screen brightness is on his lowest and still draining like 20-30% battery life each hour. Sometimes my screen even drain in stand-by mode... Every other draining apps/things are off.
And then we have random reboots... My nexus 4 just reboot without any reason. Sometimes its reboot in stand-by mode and sometimes when I use my phone. But both without any reason to reboot...?

My battery drained all the way until the "red" and a popup came up that said "Battery is less than 5 percent. Connect to charger" So I connect to charger. An hour or so later, the battery icon is "full" and green, I disconnect my charger and it immediately shoots down to red with the popup appearing again. I have tried charging it on numerous Motorola chargers, even overnight and it still happens? Anyone have this issue?

I had been using IMEasy for its multiple-account capability, I found my phone running warm when multiple accounts were connected though, and the battery drained fast; down to 70% in 3 hours in a poor signal area. I thought it was the poor signal. Installed Trillian yesterday, it's connected to 3 IM accounts and after 5 hours I'm only down to 90%, in the same area. I've been a happy Trillian user on the PC, I already had an Astra account from that so setup was SIMPLE. I HIGHLY suggest this app, though it's still in Beta and it IS missing a couple options I would like they're not critical issues to me, and I'm sure they'll fix them.
Beta is available from their site, Trillian - IM, Astra, Windows Live, Facebook, Twitter, Yahoo, MySpace, AIM, Email, and more!
I know this sounds like an ad but I'm just a happy customer.
The 2 missing items (maybe one really) are the ability to set the notification tone in the app and the ability to change the notification LED color in the app.

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?)

Alright I have one simple question. does LV SV or IV have a better battery life? I would think low voltage (LV) would cause your using a lower voltage? Correct me if im wrong

The update had to have helped. Never got battery life like this before. I'm at 14 hours 36 minutes and 60%! I do power off the phone at night when I go to bed and plug it in.
voice calls 40%
display 27%
phone idle 10%
cell standby 9%
browser 6%
android system 4%
android os 2%
backgrounds 2%
I have no task killer. GPS and wifi off. Screen brightness on 4%. Twice today I turned off News Feeds and Skype. But they keep turning back on.

I have had my DX since it came out in July. I work in a Rural area in a Cinderblock and brick building so my reception when I am at work sucks to say the least which I know kills my battery, but I have tweaked it enough that I get about 18 hours of battery life during a normal day. The problem I have noticed is that about once a week my battery goes from 80% to 10% in about 20 minutes and the back of the phone gets warm. If I pull the battery for about 10 min. It works fine for another week or so. Any one else seeing something like this?

I was all for going with Sprint from ATT to get the Evo, but with all the negative reviews of the battery life, I'm thinking about going the verizon Motorola Droid route. As you can tell the battery issue is a huge deal for me, is the Droid's battery life better than the Evo's?

Well lately my battery life has been horrid. If I am lucky I get 7-8 hours. That's with little to no internet use and just texting. Like now I'm at 70% and my phones been unplugged for 1 hour and all I have done is text a little and browse Facebook via the app for a little. I'm using BB .4 with the stock kernel. I was gettin better battery life than this before.

I just rooted last night and today my battery life has been horrible. It has been mostly idle for the entire day (since 6am, that's when i woke up) and yet it is now under 20% (at 5pm). Anyone have similar issues? Before it would last at least 20 hours...

I'm going on a hike this weekend and thought it'd be a good time to test out either Google Tracks or CardioTrainer to see elevation gain, time, speed, etc. The hike should last about 4 hours. How will my battery hold up with the GPS on the whole time? Assuming these apps have the GPS constantly draining the battery, which I imagine they do.

I've tried looking for threads on the battery life of the phone after rooting it. So far no luck. Assuming you remove bloat ware and such, shouldn't batt life improve?

I've tried BB 0.4 with two different kernels no good and kangerade 5.0.9 think. Still no good. Display is always on lowest setting possible but battery usage for display is well over 50. Only lasting 8-12 hours. First 10% drains in 10 minutes. Wtf!!! Overclock widget hasn't helped. And haven't tried setcpu. No credit card. So does setcpu improve battery life dramatically? Never had a problem with battery life before rooted Froyo. Ne suggestions? I just saw a new SS rom and new Chevy kernel. Anyone have any luck with them yet?

I have had this phone for a little over 4 days now and it is by far the best smart phone on battery life that I have ever owned. Yesterday was the best day yet, I pulled the phone off the charger at 7am yesterday and forgot to put it back on the charger before I crashed out last night. This morn I was woken up to its alarm clock, got ready, headed out to work and the last 20% warning ding'd at 6:45 this morning. My use through out the day consisted of a few short phone calls, the wifi was on all day, I played an hours worth of home run derby, I watched a few you tube videos, surfed a little net, and I have all my accounts synced up to the Motorola widgets (facebook, myspace, yahoo, hotmail, google, and twitter). I also have a live wallpaper running, lots of widgets on my home screens, and I am running the automatic battery profile ( default factory setting). Oh and my phone service is not that great at my house. In the end I my battery never hit the "red" and was a little over 24 hours of battery life before I put it on the charger. I have read threads about poor battery performance and I cant imagine why my battery performance is so good, and with such a huge screen. With that amount of use, I would only get about 12 hours of battery life from my Droid 1.

I was just wondering what settings I can tweak to improve the X's battery life after the 2.2 update. I do not want to root or uninstall bloatware, though (I did that with 2.1 and had a bitch of a time getting the OTA 2.2 to install correctly).

Received the update this morning, usually I would be at 90 or 80 percent after a couple of hours leaving the charger. Even if I was listening to music and browsing. People have been saying I'm still at 100 percent after 4 hours of playing with the phone. I was at 90 after 45 minutes after unplugging the charger. Did my battery just get worse? Anyone have this problem?

Disable the auto-screen-dimmer, immediately. Remember, even though this shows no process it still has to compute how much/little light it sees and then apply it to the screen. Kicked the brightness down to the lowest and my battery usage went from 60% screen to about 25%, how it should be.

So what are tge top killers of the battery? I know the obvious one is the screen. What else drains a huge amount of energy? Do things like multiple news feed widgets drain a lot of energy? I heard leaving GPS on absolutely wrecks your battery life as well.

My battery life didn't immediately improve. But it took a few hours for my phone to work the bugs out itself after the OTA update. I have been on this phone for 4 hours uncharged and I'm at 50%! Normally, my phone would be plugged in and getting hot.

My girlfriend just got a Motorola Droid (was using a Storm 1 before) and LOVES it. One concern we have had though has been the battery life. It lasts maybe 8-9 hours depending on how much she uses it. Is this typical for the Droid? If not, what can we do to improve the battery life? She is already using app killer and just got the phone....maybe 2 weeks ago so I would think that life would be pretty good right now. Any help would be great! Thanks guys and gals

I'm not too familiar with the Android OS, and the Droid may be my first Android device. From what I've gathered so far, battery life seems to be an issue with Android devices. I've had 3 different BlackBerrys for a couple of years now and for the most part, battery life has been good or acceptable. My question is, will the Droid suffer from battery life issues as do other Android devices, or will Motorola have a magic formula that increases it? I've read that BGR says battery life is supposed to be "very, very good." But I'm not sure I believe them. They have a way of exaggerating how good a device is, especially if no other reviewer has that device, to make it seem like they have something very special (probably to get more readers).
