HTC EVO 4G :: Android System At 98 Percent Battery Usage

Jun 8, 2010

I just wanted to know if that was normal if I'm not really using my phone. I read on another post that the Android system shouldn't be using that much battery or am I wrong?

HTC EVO 4G :: Android System Consistently 85 - 90 Percent Of Usage

Jul 6, 2010

My Son and I both have EVOs - his battery drains about twice as fast as mine. His application list is here: Kevdog83's Apps on the PC36100 When he checks "Battery Use", Android System is consistently 85-90% of usage, while Cell Standby and Phone Idle are typically the two biggest items for my usage. What runs under the umbrella of "Android System" that may be killing his battery?

HTC Incredible :: Battery Usage - Loosing 60 Percent Charge In One Hour

Jun 10, 2010

New DINC owner here, I am somewhat questing if my battery is anygood on my new phone. I unplugged my phone with a 100% charge and the green light on. I made one 4 minute phone call and viewed 4 emails and in that 10 minutes my battery went from 100% to 90%.

Stats are:
Unplugged for 10m 22s
android system 92%
voice calls 4%
cell standby 2%
WiFi 2%

Just viewing the battery use screen brought my phone down to 88%. Is this draining to fast? I also noticed last night at work I walked in with a 100% charge, I played around online a good amount and looked at some apps. Within an hour my battery life was down to about 60%. I realize these phones use a lot of battery but this one seems to be losing it's charge in a real hurry, my Blackberry was no where near this bad.

Android :: System Panel For Battery Usage By App

Aug 20, 2010

I'm having problems with my Droid Incredible battery not lasting a full day; even when I don't think I'm doing a lot. Maybe its the K9 Mail applications or my stock monitor, or some other application that is using a lot of power.

I got the System Panel application to help, but it doesn't see to give me a view of what application is using up the power.

Motorola Droid X :: Android System Sensor Usage - Possible Battery Hog

Aug 5, 2010

I just got my droid x about 2 days ago, and I've gone through about 2 full cycles. So far I haven't been able to squeeze more than 6 hrs of use on it, so I installed spare parts to see if the GPS bug was affecting it.

Going through some usage information, I found that the "Android System" sensor usage was huge! Since 1hr 29min unplugged the Sensor has been on for 1hr 36min...weird.

Checking the total time since boot the sensor has been on 19 hrs. I have autobrightness turned off and I haven't come across any other posts that explain what uses the sensor.

Motorola Droid :: Android System And Partial Wake Usage - Battery

Nov 29, 2009

There are a bunch of threads out there talking about battery usage and how to figure out what's draining your battery.

Almost all of them say to go get Spare Parts app from the market and check you "partial wake usage".

I did that and 95% of my partial wake usage is from "Android System".

Is that normal? Anyone who is getting good battery life (20+ hours) - what do you see in the partial wake usage?

I just checked my phone:

13h 10m 23s since unplugged
Partial Wakelock:Android System Total time: 13h 1m 44s

Is this normal?

The only widgets I have are:

Stock power control widget
Ringer Toggle Widget

I am running GDE in the background (not my default home screen).

Motorola Droid X :: Battery Left Says 70 Percent Left But Battery Meter In Status Bar Showed Full

Sep 30, 2010

Battery Left was the first thing I installed on my phone when I got it. My battery life has been terrible so I've been trying to track down the problem. I woke up today, unplugged my phone and didn't touch it for an hour. Battery Left says I have 70 percent left but the battery meter in the status bar showed full. I uninstalled battery left and installed Battstatt and it shows 90 percent (2 hours later). Anyone else have problems with battery left? I hope this fixes my battery problem.

HTC EVO 4G :: 62 Hours / 24 Percent Battery Remaining

May 26, 2010

62 hours and 24% battery still remaining. This is after my initial period of hammering on the phone and back to my normal daily usage pattern which is like a blackberry user (some phone calls in and out, lots of email, at least a few every 30 minutes during the day and early evening). What this means for me as a blackberry user is that I can now confidently switch over from blackberry to the Evo as primary phone and get through a normal day (16 hours) without needing a mid-day charge.

Here are settings from my testing experience that I wish I had known when I first got the EVO at Google I/O:

1. Add to home sense screen:
widget: Power Control Android
widget: settings, 4G
widget: settings: Hotspot

2. Install android market apps (free):
Advanced Task Killer
Spare Parts
K-9 Mail

3. Run Advanced Task Killer (some disagree, do what you want. I'll revisit and retest this when 2.2 gets released by HTC for the EVO. I don't need sprint navigation, sprint tv, etc. to ever be running since I will use google navigation. I haven't had time to do another endurance test without using ATK and I'm not planning to do another endurance test)

Deselect things you actually want to keep running in the background, e.g.:
voice dialer
voice search
google voice
calendar
k-9 mail
gmail
....
Kill selected apps

ATK will put a notification up at each boot and remember your selections so it's easy to re-kill off all the sprint and other apps you don't normally want 'running' in the background.

4. Turn off 4G and hotspot on the main page with widgets installed.
Note: I found I don't need to disable gps or bluetooth since with streamlined apps running nothing is using them unless I want it to and I want my bluetooth to automatically pickup when I get in the car.

5. Turn screen brightness to low or medium using widget icon. this disables auto brightness but the lower screen brightness seems fine for me. When outside in the sun just click it up if needed

6. Settings Wireless and Networks, Wi-Fi Settings, <menu button> Advanced, Wi-Fi sleep policy, Never.
It's a bit counterintuitive, but I've tested it out both ways and confirmed the articles that recommend this. The phone uses dramatically less power in this state as opposed to auto sleeping wi-fi which turns on the 3G radio. Dramatic as in without keeping wi-fi alive overnight my battery went from like 70% to almost nothing during earlier tests.

7. <optional> Run the battery from a full charge to completely drained once. I'm not sure if this had an effect or not, just putting it in because I did it once before this current long runtime since charge to make sure the battery was properly profiled. It's easy to do with 4G on and watching HD youtube videos.

8. K-9 versus gmail client. I'm seeing much more cpu usage from gmail client versus K-9. I have work email on a host service that supports imap idle (rackspace). The imap idle push seems to really save on cpu usage and my work email delivers as fast to the Evo as it does to my blackberry. I like the gmail client for my personal mail but may end up switching my gmail.com to deliver via K-9 instead to really save on battery. Needs more exploring but it appears the gmail client 'push' is not as efficient as the imap idle.

9. Summary, when you want to show off your 4G Youtube HD or use the phone as a mobile hotspot, just click on the 4G and away it goes. But normally keep that radio off since you don't actually need it and it's a huge power drain. With the widget installed this becomes an easy habit.

Motorola Droid X :: Battery Going Down From 100 Percent To 90

Sep 20, 2010

I am loving this phone, why did I ever go without a smart phone. I do have a question I have notice that after I fully charge my phone that my battery indicator goes from 100 percent to 90 percent in about an hr or so. Is that because the battery time is being rounded? So as soon as you start using it it goes to 90 percent.

HTC Droid Eris :: Google Maps Using 90 Percent Of The Battery

Apr 8, 2010

When i check my battery usage its saying that Maps has been using 90 percent of the battery. Its been doing this the last couple days even with me charging it at night. I didnt use maps at all today and its not showing up in my app manager as running, or a newly downloaded task killer. Its not really affecting my battery life which is weird and doesnt make sense. So i was just wondering if anyone else was having this problem(sorta more like inconvienence)?

General :: Text Based Battery Percent In Status Bar

Mar 14, 2012

The thread listed here is pretty old and it does not apply to my Epic Tough running 2.3.6. I am trying to accomplish the same thing but can not seem to locate any proper info on how to do it. I am still new to reading code and messing with .smali files and xml's but I have no problem learning.

I have tried the lockscreen mods but they all seem to give me Hot Reboots since most of the framework and jar files seem to have errors in them. I can deal with out the lockscreen mod but I truly like the text based battery and CM is not a choice for me at this moment until they get it stable.

HTC Droid Eris :: Battery Status Showed 60 Percent After Turning Off 3G

Feb 16, 2010

yes, it is . I charged it up Sunday night. Monday evening I still had over 60%. Monday night I did not plug it in, I tuned off 3G though. This morning the battery status still showed ~60%. So what did I do (or what did I NOT do)?

(1) I did not do the battery discharge-recharge thingy. BTW, if you really *fully* discharge a Li-ion battery you will kill it.
(2) I did not download any task killer/manager. This is supposed to be a smart phone to kill things when needed.
(3) I do not use the Home button at all. I always use the back button. my awake time is about 10%
(4) I do autosync, but my WiFi, Bluetooth and GPS is off.

I admit I am not a heavy user, though I have used up about 50 Mb data in 2 days. Peter

Motorola Droid :: Battery Life As Percent To Single Units?

Feb 7, 2010

Ive noticed on the phones status page the battery life percent only goes down in tens. Eg 90%, 80%, 70%.. etc Is it possible to narrow it down to single units like 76%? Ive tried some apps on the market but they all see the battery at 70% but i'd like to know if this is the upper or lower half of 70%!

Samsung Captivate :: Anyone Seeing Very Quick 10 Percent Battery Drop Issue?

Jul 21, 2010

Anyone seeing an issue where they charge to 100% percent overnight, pull the phone off the charger and see a very quick drop to 90%?I know the HTC Evo had this problem, and it seems like my phone is doing as well.I charge it all night, pull it off the charger and surf for like 10 minutes and the battery level plummets to 90%.Its interesting to note that if you charge the phone to 100%, turn it off and charge it, the battery indicator will display 90% and take about 10 mins to get to 100%.you then turn it on and charge it, the battery will be at 90% and will take another 10 minutes of charging to reach 100%.This is basically the HTC charging trick. After doing the charge while on/charge while off cycle several time, the battery will truly be at 100%. The problem is, I dont really want to do this every time I charge my phone.

HTC Desire :: Battery Drops 7-9 Percent Within Seconds Of Disconnecting The Charger

Aug 17, 2010

Just got a new Desire (ordered it ages ago but had to wait for the delivery with Super LCD) and sometimes, but not every time, I see that the battery drops anywhere between 7-9 percent moments after disconnecting the charger.

I'm curious whether anyone else has had this. Is this a calibration thing, or a problem with the phone, or the battery? Or an app? I'm using both Battery Indicator and JuicePlotter and they both show the same thing, the same drop. Curiously JuicePlotter tells me the drop sometimes occurs once or twice while charging in the night, too.

I'm a bit loathe to send it back to the shop after waiting well over 6 weeks for the thing in the first place, so I thought I'd check here first. I'm hoping it's just teething issues and will balance out in a few days. I got the phone about 4 days ago.

Android :: Looking For System Usage App?

Oct 15, 2010

I see that a lot of folks recommend "Spare Parts" as a app to monitor system usage. Are there any other apps out there that do the same thing? The main reason i ask is because Spare Parts doesn't seem to have the greatest reviews so i have been debating on installing it.

I main thing i want to be able to do is see what is using my battery power.

Android :: Want App To Show Built In Battery Usage

Oct 16, 2010

Here is a couple screens from my EVO. When it warns you to plug in the phone it also has a button to check usage that is built into the phone. Wish somone could build an app directly to this. As the battery was draining (almost dead) I left this screen up (waiting for it to die) total of 13hrs and 20+ min. It does not use any battery to check this. Look at how long it has been unplugged. The BT, Sprint Nav and Beautiful widgets never get killed by my task killer because these are a must for my job. I am a Professional Driver of 21 years and these are needed.

Android :: High Battery Usage - But No Use Details Listed

Oct 23, 2009

An hour after my G1 phone was fully charged, the "Battery Usage" showed me that my game had used 20% of the battery usage. Except, I never ran my game (I had run the game before starting the charge). I checked TasKiller, and it didn't list my game as running (my game also doesn't run any services). When I clicked on the details of the battery usage for my game, it didn't list anything under the "Use details" section. Is it possible to use battery, but not have anything listed under the "Use details" section?
