HTC Desire :: Android System Battery Is Draining Rapidly
Aug 1, 2010
Been having problems lately with my battery performance. im finding that the battery is being used by the android system (96%) even when the phone is on standby through the night. before it used to change to phone idle and cell standby having a high percentage with the android system staying very low, but now the battery is being eaten alive by the android system and the battery is draining rapidly.. i used to get 2 days out of my battery before it needed charging but now im lucky to get just over a day..

My battery started draining rapidly all of a sudden. I had the Seido 1750 battery. I stopped yesterday at the Verizon store and got the 2150 Battery-it is also draining quickly. I guess the Seido battery was not the problem. The battery was fully charged before I left yesterday, but it was drained completely after being off the charger for only 16 hours..5 of them I was sleeping. I do not have the GPS on...etc..None of my setting on my phone changed. I am not sure why the battery is draining so rapidly.

After noticing my battery was draining quickly, and then after reading this thread, I installed Android System Info to see what was draining my battery so fast. I notice that whenever I would turn on WiFi, the phone will never go to sleep , regardless of what I set the WiFi sleep policy to. After turning off WiFi, the battery still drains heavily.
The WiFi will shut off after 15mins (if you set it to "When screen turns off" or "never when plugged in"). However it seems to keep the CPU on causing it to drain down the battery.
It would seem that whenever WiFi is enabled, the Android system process creates a partial wakelock that does not go away even if you turn off WiFi. The only way to resolve this is by powering off or rebooting the phone.
You can verify this in Android System Info by going into Battery-History-Other Usage-Partial Wake usage to see how much time the "Android System" process holding a partial wake.
I even did a factory reset on the device; and it is still happening so it doesn't appear to be any app that caused the issue. As I said, it works fine as long as I don't enable WiFi.
I already know of two users having this issue, but I'm wondering if folks having battery problems are going through this as well. Is anyone else having similar issues after using WiFi? I'm hoping someone will be able to identify what exactly is putting the wakelock on and we'll be able to find a fix for it. Other than not using WiFi at all or rebooting the phone after using Wifi.

I have downloaded a number of widgets and apps.is this the reason? Im using Tajm, BattStatt, 3g Watchdog, DroidStats, Internal and external memory notifications, retro clock.Ive got all of these as widgets spread out over the 7 screens.Also guys if your phone was not used all day and locked how much battery would you say would get used?

A while ago I got rid of Handcent because it was very laggy following updates.Having heard this had been fixed, I have downloaded it again and it's no longer laggy which is great.However, it is draining the battery. I know this because I've had the System Panel monitor on, and the history shows that the CPU usage for Handcent is high for about 15-20 minutes after I send a message (as opposed to the stock, which just goes down as soon as I've sent a message).Is there a setting somewhere on Handcent that I'm missing, that's keeping the CPU usage high?

Just wanted to get a feel for what the consensus view in this area is, as i'm slightly torn.On one hand i've read online (here I think, and elsewhere) that fully draining the battery regularly is bad for it and will damage its cells. (I'm not sure what regularly means, daily/weekly/monthly?) Hence i'm a little cautious to do it.However I tend to get far better batter usage after draining, turning the phone off and doing a full overnight recharge. Little top-ups, like taking it from 60% (where it reached through a day of medium usage) to 100% seems to result in inferior performance.A lot of people on here talk about overnight charging, which i've no problem doing. (In fact i'm used to it as my old Samsung Omnia required it) But 'how' do people do it? As in, do you regularly use 70-80% in a day and then leave it overnight? My current behaviour is to use it throughout the day in during (odd bit of browsing, txting, app usage etc) which can take 50-60%, then get home top-up for an hour or so, which gives me about 40% back, so I know i've got plenty in the evening when out.

Got my Desire HD at the weekend, and am really struggling with the battery life, I don't use the phone much at all, couple of calls (less than an hour) checked facebook a couple of times, a read about 5 emails. Charged overnight and then by 9pm last night it was on its last legs telling me to plug it in! I have turned the apps to sync manually under settings-accounts & sync. Already used nearly 50% off the battery today and I haven't even used the phone!

Normally I wouldn't worry, but when it does crash, and I'm not paying attention to my phone, it suddenly sucks the battery big time. If it happens overnight while I'm sleeping, the battery will be dead. I just checked my phone now; last check was about 2 hours ago, it was at 90-odd percent, and now it's at 55% and com.htc.launcher is asking to be force closed. I check my battery usage, and sure enough, it's the culprit. My phone is also very hot, perhaps because it's overusing the battery. I want to avoid a factory reset. Is there any solution or known cause for this problem?

I have a problem with the battery percentage of my device, it drops from 60% - 15% but after i reboot the device it goes back to 60% and rapidly decreasing by 1% per minute until it reaches 1%. Even if it's on 1% the real charge of the battery is still there, it last for almost half a day, i just wanted to know the real charge of my phone. I don't know how to fix this i already tried calibrating but it doesn't work. I also tried using new battery and flashing to stock rom but the problem still exist.

Does anyone notice that 'Android System' battery usage is very high?
I ran a test where i displayed just a photo
Battery Indicator
3G Watchdog
Photos
Advanced Task Killer Free
within 20 minutes the results on the battery are the following:
Android System: 63%
Display: 24%
Cell standby 13%
Any thoughts on to what might be causing Android System to be so high, only them programs are running. Does this happen to your system? I notice with web browsing its about the same usage as well, with wifi and internet taking up small amounts.

What actually does that mean when you see android system in the battery consumption breakdown page? Like what parts of the phone use comprises android system, like does looking for a signal comprise system and suck like? And what is considered high android system use?

After the ota update I went from getting full day battery life with pretty heavy usage to 10 hours. The update was supposed to improve battery life but it made it worse. I tried going a day without using home++ (home replacement app ) and my battery life went from 10 to roughly 36 hours!!! So if you are one of those people complaining about battery life after update like I was,and you are using this app try taking it off. hope this helps some ppl.

What is up with this program? Everytime I open task killer it shows Amazon MP3 as running.I have NEVER used Amazon MP3. Amazon MP3 came with the phone, yet my carrier won't support it ( cough Sprint ), they say call the application provider.I can't get a phone number to Android to give them a piece of my mind.I call Amazon and get sales people that don't want to listen and dump me on anyone they can find and are the wrong people. Why can't I get support? Why can't I uninstall Amazon MP3?I don't want Amazon MP3, not if it is going to run all the time and drain my battery.

I've got a HTC Wildfire and in the last couple of days the battery has started draining really quickly. Usually I could leave my phone overnight with wifi and mobile web etc switched off and the battery would drain by a maximum of a couple of percent but now it's losing 25% of its charge overnight with nothing running. Looking at the battery usages since unplugged 3% is phone idle, 4% cell standby and 93% maps!! I haven't even used the maps for a couple of days so what could be causing this? The only apps I've downloaded in the last couple of days are WordUp!, Air Control Lite and Shopping List manager.

I would like to detect shake movement in a service that is running in the background, even when the phone is not currently being used. Is it true that the only way to do this is to hold a wake lock? I suppose this would consume a lot of energy and drain the battery very fast.Is there no way to wake up the phone whenever a shake movement occurs? Maybe with the native sdk? I would imagine the accelerometer causing some kind of interrupt.

My wife's phone has used almost 4GB of data this month and her battery has been draining much faster than mine, especially at night. Last night we watched in SystemPanel at the Net Receive indicator and it was constantly downloading at least 200+ kps. I had read about some issues with Facebook so we removed the Friendstream widget and saw the downloading go close to zero.
This morning, I checked the 8 hour monitoring in SystemPanel and saw that the CPU activity was still high overnight (running near 30%) and her battery drain was twice mine (over 13% used over ~7 hours, mine was around 5% drain).
I loaded up Spare Parts on her phone and was looked under Battery History, Network Usage and took this picture (sorry about the quality, her screen protector makes it hard to get a good picture and she is not rooted). Can anyone explain what UID 10006 is and why it is downloading so much data? I do not see it listed on my phone in Spare Parts. What do we need to do to turn this off or at least slow it down?

I am using BB V0.4 with Chevys 1.2 ghz ul kernel.My battery meter has been on 100% all morning normally it drains much faster than this. I know there is a CHANCE my battery just isn't being drained because of the 1.2 ghz ul, but it seems pretty slim to me. I have been using it for probably 4 hours without it going down form 100%.

Battery life issues for me are over. In the beggining I would be happy if the battery lasted for 2 days. Now I can have my phone always on for 7 days straight, that is 168 hrs (when using very limited wireless data connectivity of course), thanks to Galaxhero and some other tweaks.But anyway, lately I've been doing some tests regarding Google Latitude. I suspected that Latitude was messing (not just) a little bit with the battery life.So, yesterday at 9AM I unplugged the fully charged phone that had the Latitude feature on. Result: at 5PM the battery was at 90%.Today, I decided to turn off Latitude (leaving the rest of the configurations intact) and unplugged the fully charged phone again at 9AM. Result: it's 5PM and the battery status is at 100%.

This is my first smart phone so I'm somewhat of a noob.However recently when I have been checking what has been using my battery the most to try and conserve some battery.My GPS is always off unless I need it and I have not even used Maps at all today. After about 8 hours of being unplugged I was down to about 30% battery life.

The last day or so after charging my phone to 100% overnight (phone is on when charging) and then putting in standby mode I'm losing like 5-7% of battery every hour.Over the weekend I was losing just 6% every 9 hours in standby mode. Today in 4 hours time I'm down to 65% already with mostly standby mode and a few minutes of browsing. I even had JuiceDefender installed since last night and it's not helping at all.To me it seems that something is in the background that is draining the battery though I when I check running services I don't see anything that shouldn't be there. When I was losing only 6% every 10 hours I did have a live wallpaper, weather/clock widget, and task killer. I didn't change anything on the next charge and now I'm constantly losing battery even in standby mode.
I have Wifi/GPS/background data off, brightness at minimum, no animations, etc. So pretty much followed all the battery saving pointers. I thought it was working good when I got just about 36 hours over the weekend with standby and moderate usage. So I don't know what has happened to my battery all of a sudden.The two times that I have managed to do 30+ hours on a single charge I had Advanced Task Killer running.However, even after doing 36 hours on one charge the next day even with ATK the battery started to drain a lot every hour in just standby. Anyone else having similar issues? I don't know what else to do at this time. I've uninstalled many of the apps thinking it might one of them causing the issue, but still having issues.

Following my last thread for same reason,"full charge battery goes empty in less then 3-4 hours,even with wi-fi,gps, turned off",with tip of you guys,i monitored battery usage with "spare parts" app,first i haven't notice anything unusual: SPARE PARTS gave me very normal cpu usage:1-android system2-browser, but then in the end of list of usage option,i checked other usage & what i found was very interesting:
SPARE PARTS>battery history>other usage>total in all time:
running =time without sleeping 28.1 %
SPARE PARTS>battery history>other usage>since last unplugged:
running =time spend without sleeping 99.999 %
SPARE PARTS>battery history>other usage>total since boot:
running=time spend without sleeping 99.999 %
Now i guess i know why my phone run out of charge in less then 3-4 hours,question is what i have to do about it?
any solution please? previous post:with a full charge battery in STAND-BY, it takes just about 3-4 hours for battery to be empty! help!
also i checked main setting now: setting>about phone>status>Awake time 100%

Over the weekend my battery was pretty good until I started playing with google maps. I accidently turned privacy on to lattitude and my battery was draining even though GPS was off. Lattitude will find you through tower location whcih uses cellular power! Much better this morning when I turned this feature off. In fact google sent me an email letting me know I forgot to turn it off.

Just 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?

I'm trying to find out why my phone's battery is draining so quickly all of a sudden. I used to have pretty good battery life but now for some reason I do not. Haven't installed any recent apps so I don't know what is doing it. I installed systempanel lite but I think i have to buy the paid version to get it to monitor it. is that correct?
