Why the time above the adroid bat graph and the one below are different. At this moment is says on my device 1h 28 minutes on battery. Below the graph 50m 22s is shown. What is the difference between those timers ?

Recently bought a Polaroid PMID701C tablet. I was looking for that battery consumption graph that is on most android phones/tablets. The one where it shows which apps and hardware are consuming the most power. i couldn't find it and gave up. until one day when a low battery warning appeared on the screen. usually i cancel it, but this one time i clicked OK and it brought me to the battery consumption graph i was looking for.
seems to be the only way i can access it. i understand that this tablet is entry level, but shouldn't i be able to get to this without having to wait for a low battery warning?
I'm on a rooted v2.3.4 phone.
The stock battery usage graph screen doesn't show any apps, only core Android elements like Phone Idle, WiFi, Display, etc.
It's not because apps didn't use enough CPU time.
No root..Firmware v. B104...New phone, got it in late December 2012. Handled with great care. Battery icon and battery graph stuck on 50%. Never know how much battery juice I've got left. No warnings, just powers off when it's empty.
Tried:
- Factory reset
- Attempted hard reset, but I'm not sure it worked, 'cause nothing special happened on my screen.
- Completely draining the battery (as an equivalent to removing the battery. Non-removable battery on this one)
I have been looking for firmware updates, but I can't find any for my B104, and if I have understood it correctly, applying an update for the B226 will most probably render my device useless.I am quite satisfied with this phone, it is magnificent, so I do not want to root it unless I absolutely have to.

I propose that we all post our battery life graph like the one I am about to post below. This way we can look at these claims in scrutiny, and perhaps figure out why it is that some people's Evos seem to last longer than others. Here is a graph of my Evo's Battery Charge over 1 day:
Wake up at 7:30am to disconnect the charger, listen to Pandora on the car to work until I arrive at 8am. Idles until lunch time at 12pm. Use the Evo to read up on some news at lunch until 1:30pm. Listen to Pandora while working until 5pm. Drive home while listening to Pandora in the car. Battery starts giving warning indications while driving, and phone dies when I get home at 6pm. Very usual day, and matches what the battery charge graph shows. The top apps of the day are:
System Processes contains mediaserver (2.4% due to Pandora), akmd (0.3% accelerometer polling), and everything else is <0.1%. As you can see I barely used my phone during the day for anything but Pandora. So based on my data, I'd say that the normal battery life for the Evo is under 10 hours. My settings are: no 4g, no wifi, no bluetooth, yes gps, yes bckgrnd data, auto brightness, no live wallpaper, yes taskmanager (ATK, set to "safe" setting. Will probably get rid of this..), no friend stream, no flickr.
I'd love to see other people post up their Battery Usage graphs as well. The App used is "SystemPanel App / Task Manager", available for free in the market. Go into Settings and allow it to Monitor. The screenshots were made by ShootMe, also available in the market.
Managing just 8-9 hrs with ny battery, and believe me I barely use the phone! Just a few calls, few texts, 5 min Internet, 5 min face book - thats it. I have everything turned off that I can turn off. Come on HTC sort it out - this is obviously by far the worst criticism you have.

View 2 Replies View RelatedI know how to use AsyncTask in a standard manner to manage operations that are in the background in relation to a UI thread.However,I want to run a task in the background which might run for a very long time under certain circumstances. In these cases, I would like to force the background task to fail if it runs for an excessive amount of time.I know that I can invoke the "get(long timeout, TimeUnit unit)" method of AsyncTask in my UI thread in order to terminate my background task if it runs too long. However, in that case, my UI will block while this "get()" command is waiting.There are probably other drawbacks to directly calling "get()" in this manner, not the least of which being an evil interaction with the "done()" method of AsyncTask's contained FutureTask object, which itself is calling "get()" at least this is what I see when I look at the source code for AsyncTask.

View 2 Replies View RelatedI wanted to ask a question regarding the Alarm Manager. I have a requirements of setting long running timers in my application. The minimum duration for my timer is 1 hour...and the maximum may be for 4-5 days. This timer is supposed to run in the background, and when it fires/expires, i have to show something on the GUI. The timer can be re-scheduled once it fires based on user action.
What is the best approach for scheduling such long running timers ?
Should i make use of the Alarm Manager ? Or will it be an overkill ? As far as i know, alarms are retained even if the device goes to sleep and they wake up the device when the alarm goes off.
I am thinking of using a simple Java TimerTask as an alternative to setting an alarm: http://java.sun.com/j2se/1.5.0/docs/api/java/util/TimerTask.html.
But i am not sure what will happen to the timer task if the device went to sleep while the task was running.
I'm doing my thesis work on resource management on android and I want to be able to measure the "responsiveness" of an application to figure out if the application get enough resources and is scheduled often enough.
So what I want is a way to insert timestamps on events, e.g. button clicks, when they are created and when they are consumed. This way I can get the "responsiveness" of the application. But I have a hard time of finding exactly where the events are created and also consumed.
In Handler.java there is the handleCallback(Message message) method which I can insert the end time stamp. I tried to add a long variable in the Message class and that worked well (had to rebuild the api though). So my problem is to find the place where the button click is generated and where the message that corresponds to that event is being created so I can add a time stamp.
I also welcome other suggestions on how to measure the "responsiveness" of an application or other way to measure how well an application performs.
I'm very new to the Android platform, but i was hoping to write a quick and neat little android app which will receive data from blue tooth and to graph the data. I'm trying to use a LM Technologies LM049 blue tooth adapter to send serial data to my HTC Dersire 2.1 android handset. At the moment i'm trying to just prove i can send ascii characters to the phone. Not quite sure where to begin.

View 2 Replies View RelatedI had a bunch of code in an activity that displays a running graph of some external data. As the activity code was getting kind of cluttered, I decided to extract this code and create a GraphView class:
public class GraphView extends LinearLayout {
public GraphView(Context context, AttributeSet attrs) {
super(context, attrs);
LayoutInflater inflater = (LayoutInflater)
context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
inflater.inflate(R.layout.graph_view, this, true);
}
public void start() {
// Perform initialization (bindings, timers, etc) here
}
public void stop() {
// Unbind, destroy timers, } }
Moving stuff into this new LinearLayout-derived class was simple. But there was some lifecycle management code associated with creating and destroying timers and event listeners used by this graph (I didn't want this thing polling in the background if the activity was paused, for example). Coming from a MS Windows background, I kind of expected to find overridable onCreate() and onDestroy() methods or something similar, but I haven't found anything of the sort in LinearLayout (or any of its inherited members). Having to leave all of this initialization code in the Activity, and then having to pass it into the view seemed like it defeated the original purpose of encapsulating all of this code into a reusable view. I ended up adding two additional public methods to my view: start() and stop(). I make these calls from the activity's onResume() and onPause() methods respectively. This seems to work, but it feels like I'm using duct tape here. Does anyone know how this is typically done?
I was curious about the nature of the handleMessage() and sendMessage() behavior of the Handler class. I want to be able to send message to another thread in such a way that the destination thread can process the message queue when it wants to. It seems, however, that the message is processed by handleMessage() practically as soon as it's sent.
I'm trying to design a game loop thread that does something like this:
CODE:.....
However, I as soon as sendMessage() is called (from the parent/calling thread), the Handler.handleMessage() is processed (in the child/receiving thread), even if the child/receiving thread is blocking in a while loop.
I've seen this problem solved in other games by using a thread-safe list (ConcurrentLinkedQueue). The UI thread just posts events to this queue, and the game loop can remove the events as it seems fit. I just assumed the Handler class was designed for this purpose. It seems it's more intended for asynchronous callbacks to the parent thread.
Is anyone else having issues with connections to the hotspot timing out when trying to connect or when already connected? I have tried to search around before posting but even most of my friends haven't come across this issue yet.

I changed some settings on my incoming mail and cleared cache. What else am I missing? I hope a stronger longer lasting battery will be forthcoming.
View 11 Replies View RelatedNew EVO user here as of last Friday. I've done a ton of searching, watching and reading and I have a couple questions to the experts out there.
Please let me know if there is a way to stop the screen from timing out (going dark) during a phone call. I find it annoying to have to hit the power button to get the screen back..
I'm using earbuds so the phone isn't near my face and it recognizes the phones as I can see the headset icon. I keep the phone on my desk and the screen times out almost immediately after I make a call and accept an incoming call. It's extremely annoying since I make a ton of work calls and I need to either navigate through an auto attendant and / or leave a message. All of which I have to hit the power button every single time I want the screen to turn back on. I have noticed that the volume buttons turn the screen back on as well.
The screen timeout is set at 2 minutes under the "Sound & Display" category but that doesn't effect the screen time out during a call. Anyone out there have a solution?
My Droid goes to sleep in the middle of my Youtube videos. Is there a way to stop it from shutting down/timing out without setting the Droids timeout to a longer time setting? I have it set for 1 min.

View 2 Replies View RelatedSo I have a very weird yet unique case with my stock text messaging app. Just this past weekend I started noticing that one of my contacts text messages were consistently showing up 3 minutes earlier from my text to them. So every time I send a text their response shows up above it which is very annoying. This case is only occurring for this contact, everyone else shows up just fine.
Now, this is what I have determined so far...
1) It's only happening when I receive a text from someone using a DROID on Verizon. I had a another friend who I had not recently text with sent me a text message to test my theory. The issue still occurs...
2) I had my sister who is on Verizon text me on her Blackberry Tour and the timing of her text shows up correctly. So it can't be the network right?
3) 3rd party apps (Handcent/ChompSMS) don't have this issue at all, the timing is perfect for everyone so my guess is that there is something wrong with the stock messaging app?
I have a whole bunch of other text from other contacts and I don't have this issue, it's just happening to the one contact that I have...actually, now two, which both have a DROID.
I may have to commit to using Handcent but I've been testing out the stock messaging app lately to evaluate the wake time after the firmware update and just noticed this problem occurring this past weekend only. I was using the stock messaging app even before this weekend and didn't notice this problem.
