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?
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.
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.
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.
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.
I have an app that uses quite a few graphics in it. When I open and close my app repeatedly on my emulator (1.5 - 2.2) it runs fine and by checking the heap I can see everything is being cleaned and gc'd properly. However, when I run my app on an HTC Aria phone (2.1) the app crashes every time I try to re-open it. When I look at the heap I can see that objects are NOT being cleaned up like they are in the emulator. Does anyone know why this behavior could be happening? I did try it on another HTC Aria (a friends) and it crashed the same way as on my phone so I think it's not just isolated to my particular phone. Any thoughts or ideas would be really appreciated on why things are cleaning up properly on the emulator, but not on my phone. One thing to note, is that I DID have it working and gc'ing fine on my phone a few days ago and I didn't change much and now it's not working on my phone so it's a bit of a mystery to me.
My question is a very simple one I'm sure. It's just I'm not quite sure how to effectively describe what I'm trying to achieve.
Anyway to the point, I have a simple button, I know how to "link" a raw sound file to hand make it play. BUT what i want to do is maybe link a 3 second sound to the button and just have it loop while the user holds the button, and then stops playing when the button is let go. Anyone have any example links they could share that would be great!
Has anybody managed to get GPS working consistently after flashing Villain? I managed to get a fix on my location once and that's it. I have updated to the latest radio, and I have been trying it outside.
Since the update my WiFi will not stay consistently connected to my home network. Sometimes I have to go in and force it to connect. I have deleted my connection and created a new one. Any one else having this problem?
I've had an issue w/ my Internet browser closing on me for quite a while. It just closes down to where ever I was before the Internet was launched, w/o a "force close" message box. This has happened across many diff ROMs, many diff browsers, and many diff kernels. Hell, it's been happening since at least 2.1 and perhaps 2.0.1. I've tried clearing caches, wifi, lowering the kernel MHz, yet the issues still persist. Sometimes it happens instantaneously upon opening, sometimes it waits till I'm enjoying surfing away from my pc.
I have an Android project that I have been working on and debugging just fine for several months, but for some reason it is now consistently hanging at the "Runnning tests..." step. I have experienced intermittent hangs from the beginning, but a simple retry and/or restart of Eclipse or the emulator usually resolves it. But now I am just dead in the water.I can run my tests fine, and I can debug my actual program, but I can't debug my tests.I have tried creating a new emulator and that doesn't fix it. I also cleared all my breakpoints and that had no effect.As far as what has changed lately, the primary thing is that I upgraded to rev 7 of the SDK tools. Also, I recently did some debugging (of the program not the tests) on an actual device (not the emulator). Can't see how that would impact it but I thought I would mention it.Actually I had to set Debuggable to "true" in the app manifest to get device debugging to work. Although I have never had that set in my test project, I set it, and that also had no effect on the issue.I'm running out of ideas, and I would greatly appreciate some pointers.
I don't know if it's my phone or what but when I look up the Other Usage on my phone, it shows it "Running" more than 2/3 of the time.And on Network Usage, "Android System" and "Media" use a great deal of the phone as well.I think this might have to do with my "android.process.acore" crashing every once in a while when it's asleep. Based on everyone's feedback I might have to return the Moment for a third time.
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.
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.
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)?
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.
I own a Jiayu G4 Advanced for about a week now and I have been having these weird battery drops. Whenever it reaches about 40%, it drains to about 10% in just minutes. I already tried battery calibration, newer version of the ROM and even a factory reset without result...
I am trying to assign relative widths to columns in a ListView that is in a TabHost, using layout_weight as suggested here:Unfortunately, it seems to want to fit all the columns into the space that the button occupies, as opposed to the width of the screen. Or maybe there is another constraint that I do not understand.
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
I would say within 5 minutes of taking the phone off of the charger, the battery drops to 90%. I'm running stock software (2.1), ran the *228 option 2, turned off GPS tried anything simple I could find by searching.
