6hr Battery Life, OS using 40%????

[racermech]

Over the last 2 days I have been seeing a major battery drain issue. I unplug the phone in the morning, check a few things and go to work. Some emails couple phone calls. By thr 5 to 6 hr mark the battery is at 15% or less. I look at usage and OS is reporting over40% of a battery life. Display and phone idel are both 10%, calls and sell standby are 8%, Android system is 7%. Everything else like facebook, browser, gmail are all 2-3%.

Any ideas as to why the OS is running so much? No new apps the last couple of days and my use has been light to say the least. 3G service has been good, wifi off and gps on but not showing it has been used.

I don't have your issue of the OS using 40%, but I've noticed decreased battery life as well. I haven't done extensive checking like I should before saying anything, but my display is at 50% use right now, for instance. I haven't changed any settings on it; it's set to auto brightness and times out after 30 seconds, plus I always lock the phone right after use (all of which is how it's been set up since I got the phone).

I'll be sure to do some more investigating of what is using the battery the most after right now and come back to this. Just thought I'd throw my situation out there, too, because it feels like my battery has suddenly decided to not last as long over the past few days. Hmm, if not a week or bit more.

My Evo 4G has always had a problem of the Android System taking major battery life such as around 40% on a daily basis. Is there anything I can do to stop this from happening and extend my battery life?

Odd. On a normal usage day for me, my voice service is spotty for about 30 minutes from power on time untill I reach civilation. Also keep in mind that once I arrive at work, I'm a few hundred yards from a tower. I don't use Live Wallpapers and consume quite a bit of WiFi throughout the day including Facebook updates, constant email usage and misc data here and there. A full days usage while I'm at home generally gives me about an hour less battery life vs being at work Current specs after today's usage are below.

display: %26
WiFi: %15
Phone Idle: %14
Cell Standby: %11
Android System: %8
Android OS: %7

Once home, I freshen up the battery charge for appx an hour till full then shutdown my phone at bedtime. It gets powered back on @ 5am daily. It's 7:30pm here now and I'm at a solid %50 remaining. This battery behavior has been constant with me from the stock unrooted rom and several different versions of CM6 including the newest release candidate.

I have had the same issues. Only its the display that uses the most of my battery life. Even though I have it set to 0 all day long with a timeout of 1 minute. today it has been my phone that took up most of the battery and i only used it for 15 minutes total since 7:00am this morning. I am at 20% and its 9:30pm here, but I had it plugged in for an hour at work. Something just isn't right. I ordered a new battery to see if its a hardware issue.

Ratchet, Don't you have to be rooted to use CM6??

 

[Ratchet]

Ratchet, Don't you have to be rooted to use CM6??

Yes you do. In my honest opinion, prob the best thing I've done regarding the D1. There are roms out there that offer what the stock rom lacks. The performance tweaks in most of the custom roms really wakes these phones up.

So last night i removed a couple of apps and rebooted the phone. Seems to be a bit better as of right now. Yesterday I unplugged the phone from work, drove home with the phone sitting out the whole time. When I picked it up the phone was hot and the OS was at over 40% use again. I stopped off to vote and I could feel the phone getting hot in my pocket. Something was running the OS without showing up as a running app. The most recent app I installed was that instant heart rate, it was one of the ones i removed.

If you're worried about it enough to buy a new battery, try a factory reset. Run it for a day without any apps and check the usage. Then you can install a couple apps a day to see if one of them is the problem.

Is 15% after 7 hr and 23 mins good?

 

[Sploinkin]

I had 15% after 14 hours 43 minutes and that was playing Snesoid for about an hour, so no, that isn't terribly good.

7 hour battery life is bad. You have a widget or app that is stealing your power. The most likely culprits are streaming music, music players, or social media apps or widgets.

See the Getting Started with Android - Tips and Tricks, Battery Life Tips and Tricks section for much more but this part will get you started.

Find the Battery Sucker
If your battery is draining fast, turn everything off and then start turning things on until you find the problem.
1. Save your current Homescreen Scene: Tap Menu > Settings > Personalize > Scene > Menu > Save.
2. Turn off radios: Tap Menu > Settings > Personalize > Wireless & Networks. Turn off WiFi, Bluetooth, Hotspot, 4G, Mobile Network.
3. Remove live wallpaper: Tap Menu > Settings > Personalize > Home wallpaper. Chose a wallpaper that is not Live.
4. Remove all widgets. Use App Icons for now.
5. Dim the brightness to 25% or less: Tap Menu > Settings > Brightness
6. Reduce auto-sync: Tap Menu > Settings > Accounts & sync. Turn off ones you don't use. Slow down the rest.
7. Reboot the phone: Press and hold the power button then tap Power off. Then turn the phone back on.
8. Take the phone off the charger and note the Battery %: Tap Menu > Settings > About phone > Battery.
9. Turn off the display and check the Battery in an hour. It should drop by no more than 2%.
- If drop was over 2%, check for rogue apps: Tap Menu > Settings > Applications > Manage applications > Running.
- - Are apps you installed running without you turning them on? Tap it then tap Force close.
- If drop was under 2%, start turning apps on until you find the problems.

After being unplugged for 4 hrs and 45 mins I'm only down to 60% today which is better than yesterday. I'm not rooted or anything so this is the stock Droid OS! Pretty satisfactory to me I guess.

 

[mumfoau]

Wow....today after 7:30, I'm only down to 50%. I have haptic feedback off which is the primary difference. Wonder if it really has that much of an affect?

 

[Ratchet]

Not sure on the haptic unless you type 100wpm constantly for several hours at a time. I use haptic, but mainly for lockscreen and home quick keys. Prefer no audio or haptic feedback for keyboard usage.

Hubby was having this problem a couple of weeks ago. He uninstalled Weather.com app and LookOut and hasn't had the problem since. I have a refurb Droid and use both Weather and LookOut and I don't have this problem, however. Just thought I should contribute since we just experienced this.

 

[mumfoau]

maybe it's all in my mind but for me the signal strength is big for battery life. at work, i'm in spots where i'm constantly switching between 1x and 3g. i was at home the last 2 days with 3-5 bars of 3g and connect to wi-fi the whole time and today, for example, after 9.5 hrs i was only down to 50%!!!

 

[azzer2000]

I have this problem. the phone works fine for a day or so, then some program must crash, i can tell the phone has slowed down then i check the battery usage and androidOS is there on 40 odd %. Restart the phone and everything goes back to normal, but surley i shouldnt have to do this. This is on a HTC desire HD runing 2.2.

 

[pstellato73]

I do this as well. When I take it off the charger and use it for a few hours the battery shows 40-50%. I reboot and it goes up to 80-90%. Why does it do this? After heavy usage the battery drains at a ridiculous rate, then you reboot and it seems to fix itself. I reboot 1-2 times per day and according to most, the android OS should not need this, but I find I do. I am rooted using CM6.

I waited to log in on this since usually it's an app update that's causing the trouble, and then it gets fixed. For over a week now, my Droid is draining faster than water going out of Niagra Falls...I have cleared all the caches, monitor closely what's running in the settings, deleted anything suspicious that I can live without, etc. At night, it's in Airplane mode, and will drain from 60-70% down to 20-30%!! I've never seen that. Previously, it would drop a mere 10-20% overnight, and I could charge every other day with light use. Now, I'm charging 2-3x per day with the same use. Something's gone very wrong.

 

[Sploinkin]

I got my Droid over a year ago, and noticed that recently the battery level would drop from 50% to about 20% in a matter of seconds. I'm guessing that if you were an early adopter and a moderate user, your battery is starting to kick the bucket.
