HTC EVO 4G : Unusual Battery Drain - Phone Won't Go Into Sleep Mode
Nov 13, 2010
Last two days my battery has been draining like crazy and my phone won't go into sleep mode. I charge before I go to sleep and take it off when it's done and it will die before I wake up in about 8 hours .
Use to be at like 97 or 95 when I get up
I've gotten pretty good at managing my battery life , I use superpower and juiceplotter to monitor it .normally I waist less than 1% an hour when not in use and the phone is asleep
I've deleted every app I've installed since 1 day before this started. Only thing unusual I see in my logs is this message (Adding Alarm{464294e8 type 2 com.android.phone })
And this
Alarm triggering: Alarm{46354990 type 2 com.google.android.location} Adding Alarm{465bbb80 type 2 com.google.android.location }non stop repeatedly every second when phone is not in use.

Many of us have experienced some battery life fall out since the last update. I mentioned this in the battery life thread but I thought it deserved it own topic. I have an app that I downloaded called battery status. it has a battery history. and it says time without sleeping 7h 10m 25s ago. Thats exactally when I unplugged my phone. This explains why I am seeing 2-3% per hour loss while not using the phone and while in airplane mode. Before the update I could keep the phone in airplane mode, not usre it, and leave work with over 94% battery life. So this proves that somehow the phone is not going into sleep mode... I can guarantee that everyone else in that is experiencing battery drain since the sept 16th update is due to this reason. The question is... why the hell is this happening and why won't the phone go into sleep mode?

I'm having problem with my Nexus 7. I have Android 4.2.1 on it. I've been using it for about a week now and every night i would turn it off, but in the last few nights, i decided to leave it on sleep mode to see how the battery life was.
On the google site, it says that the Nexus 7 should have 300 hours of standby. Is that the same as 300 hours of sleep? Because when I left my Nexus 7 on overnight, it drained from 55% to 33% in about 8 hours. That doesnt seem like 300 hours to me.
Also, I've tested it again, started at 100%, no wifi, no gps, no apps running in background, no syncing, in sleep mode, and it's draining at about 2% and hour. I've read on this forum that people have been getting like 2% every 8 hours on sleep, or even overnight. I've never used 4.1.1 so I dont have anything to compare it too. Does the 300 hour standby time mean powered off Nexus?

What is your take on the WiFi sleep policy. I do like the fact that Wi-Fi can remain on all the time, but will it be a drain on my battery? Is it better to keep the Wi-Fi to sleep on screen shut off? I am near a Wi-Fi connection for most of the day and always at home.

I apologize if these topics were already covered in previous threads.I wasn't able to find anything related in my searches. Auto-rotation for keyboard when answering a text message received in sleep mode does not work. If I actively send a text when phone is already awake, keyboard rotates with no problem but when I go to reply to a text that I received while phone is in sleep mode, the keyboard does not rotate. Is this the norm?I am also experiencing a delay when the I wake the phone. After unlocking the phone, I used to go straight to my home page, now I get a "loading" message which takes several seconds. Is this due to the number of apps I have loaded? Is it possibly due to number of photo frames I have on my home screen or the complexity of the wallpaper?

my Samsung s2 on jelly bean 4.1.2 drains battery alot while even in off mode not only that, whenever I press the switch off key the phone won't give me various options of restart, flight mode , sound mode and the likes, the phone will just go into off mode directly.

I'm really not "using" my Android S3 phone all day long, it gets frustrating when the bettery runs at 30% at 2pm, without any real use.
So the concept would be:
1) either a "ROM" of Android, which would be seriously minimal - like the device is not a smartphone - so only wake up on incoming call or text message
2) or an app, which does the same thing - suspends the phone completely, and wakes it up only on the incoming call or text message
I was just curious - does something like this exist? I don't care about apps, notifications, wifi or sync, I was thinking more along the lines of would it be possible to use your smartphone like a typical "cell phone", and when you need other apps or full features (GPS navigation with maps, or Shazam, or whatever it is you need) - you just "reboot" or do a quick switch to "full Android" mode, and use those features.
I feel that the battery life should be at least 5 days in that mode, with light usage?

Night before last, I charged the battery to 100% before I went to sleep. When I was going to sleep, I unplugged it. When I woke up 7 hours later, it had only dropped 30% to 70%. I did the software upgrade, and the battery jumped back up to 80% and lasted a Long time. Well, last night, I did the same thing, and when I woke up, my battery had dropped to 50%. The phone was supposedly sleeping this whole time! A few minutes on the browser to look up the issue brought me down to 40%.
All I installed yesterday was YellowPages, WhitePages, Flikie (then uninstalled it) and LauncherPro (could this be the culprit?). Before I went to bed though, I opened GMail, and it was having trouble connecting to the server and finally gave me a "retry" button because it couldn't connect. I never pressed it and just went to sleep. WiFi, GPS, everything was off, and the screen was set to lowest brightness (which doesn't even matter here.) Why it dropped so much?

Over the last week or so I've been obsessed with trying to get my hero into sleep mode, in order to save battery. For those who don't know about this, there are many threads around the net telling of a fix for the messages bug, which prevents the phone entering sleep. It's supposed to reduce CPU usage, thus saving battery.
Now, I've followed the methods of many people who claim to have done this successfully, down to a tee, but for the life of me, I can't get it to work. For some reason my awake time is always at 100%. It's now at the pont of driving me mad, and I'm just wondering if anyone else has tried and failed to do the fix. If anyone needs background info on this problem, I'll post a link up later, as I'm sending this via my phone at the minute.

I'm developping a LiveWallpaper on Android 2.1. This application must download an image every fifteen minutes and draw it on the screen. Everything works except when the phone is in sleep mode. Do you think it is possible to run an application like this when the phone is in sleep mode? And if yes how?

i just got a htc desire 5days ago i moved over from a iPhone 3G. I have a big problem with it. Battery lasts for about 4-5h i have read forums and googeld for 2 days now.So far i changed my Background to a black one i made wifi turn off after 15min no Bluetooth etc.I think the problem is that my phone never goes in to sleep mode.when i go setting > about phone > battery the up time and awake time is the same.I downloaded advance task killer but the only program i can see running is Smart Keyboard Pro and Amazon. I kill amazon and it stays dead for sometime i cant kill smart keyboard pro it restarts it self straight away.I have had the phone on charge for about 6h now and the battery seams stuck half way and don't relay increase or its increasing very slowly.

Is there any way to detect whether an android phone is in sleep mode (screen is black) in the code?I wrote a home screen widget. I don't want the widget gets updated when the screen is black to save the battery consumption.

I have a service which polls a server at certain intervals. I use an AlarmManager and a BroadcastReceiver to start the service. My problem is that after a certain duration, even though the WiFi is still enabled, but for some reason, my application can't contact the server. I get an "Unreachable network" error. Note that I've already acquired a partial wake lock as well as a wifilock. Here's my code for the BroadcastReceiver.
public class ServiceAlarmBroadcastReceiver extends BroadcastReceiver {
public void onReceive(Context context, Intent intent) {
WakeLock wakeLock = null; WifiLock wifiLock = null;
try { PowerManager pm = (PowerManager) context .getSystemService(Context.POWER_SERVICE);
// acquire a WakeLock to keep the CPU running
wakeLock = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "MyWakeLock");
if(!wakeLock.isHeld()){ wakeLock.acquire();
} Log.i("ServiceAlarmBroadcastReceiver", "WakeLock acquired!");
WifiManager wm = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
wifiLock = wm.createWifiLock(WifiManager.WIFI_MODE_FULL , "MyWifiLock");
if(!wifiLock.isHeld()){ wifiLock.acquire();
} Log.i("ServiceAlarmBroadcastReceiver", "WifiLock acquired!");
context.startService(new Intent(context, ThePollerService.class));
} finally { // release the WakeLock to allow CPU to sleep
if (wakeLock != null) { if (wakeLock.isHeld()) {
wakeLock.release(); Log.i("ServiceAlarmBroadcastReceiver", "WakeLock released!");
} } // release the WifiLock if (wifiLock != null) { if (wifiLock.isHeld()) { wifiLock.release();
Log.i("ServiceAlarmBroadcastReceiver", "WiFi Lock released!"); } } } } }

Until yesterday if I had an app like Pandora or ESPN Radio playing/running when the screen kicked off the app would keep playing. However, now when the phone goes to sleep everything else gets shut off. I have not altered anything myself per se. Even uninstalled a few apps like AutoKiller [which I had installed for weeks and everything worked fine with it on and installed] but the problem persists and remains. This really perplexes me as I want/need these apps to play with the screen off like they did before. For the life of me I don't know why this is; nor can I find anything in settings to change.

I was investigating the issue of setting up a delayed activity/event, that will occur and trigger even if the phone is in sleep mode (wake up, do what you need to do, go back to sleep). I was thinking of the following methods: 1. sendMessageDelayed 2. Timer 3. AlarmManager.The basic requirement is to be able to set a triger in the future, and be sure that this trigger wakes up the system if it is sleeping,perform the task, and go back to sleep.A partial wakup is required (no screen flickering). Currently i'm using the sendMessageDelayed, and i keep a wake lock held for the timeout period (bad practice).

I can't be 100% sure which one it is. But I installed Nonsensikal 13.2 about a week ago, love it, and was about to basically settle on this as my default rom until Saturday. Starting Saturday my phone has become non-responsive about 5-6 times. Meanin the lock screen won't come on, and the power button will not turn the phone on or off.I'm assuming this means that the phone is still on when this happens, because if it had just powered down randomly I'd think the power button would turn the phone back on I have to pull the battery out and power it back on to start working again. I don't have setcpu or autokiller running, but I am running juicedefender (in case any of that is helpful for anybody.)

Is there any way to get an email or text notification once my phone is in sleep mode? If my phone is "awake" it rings but once asleep I don't get any notification. Also, if my phone ringer is set to vibrate is there any way to set my email/text notification to ring or does it have to be both vibrating or both ringing.

My Incredible rings when there's a visible screen. When the screen darkens and phone enters sleep after, in my case 1 minute of non-use, any calls coming in do not ring through. Voicemail picks them up but there is no indication that I have an incoming call unless I wake the phone up and check the upper left hand menu for the voicemail icon. This can't be set up right. When the phone is asleep (dark screen) but not powered off, there has got to be a setting that lets calls ring through and awaken the phone so it can be answered.

I took my phone out of sleep mode to respond to a text message, only to find I couldn't get the keyboard into landscape mode. I then found that the trackball wasn't working, and the phone seemed as if it was moving through puddy. When I tried putting it to sleep, the screen would dim but not go black. I eventually had to remove the battery to resolve the issue. The next day, the same thing happened.
Both times, the issue happened at around 8 o'clock. I thought thru what apps I had downloaded recently, and looked through Astrid To-Do. I found it had scheduled back-ups at 8 o'clock. I turned that off, hoping that it would fix my problems. The next day, at 8 o'clock, my phone randomly restarted. That was all. No overheating, no hanging, and it booted up just fine. The next day, it rebooted again, but I don't know if it was around 8 o'clock. Today, just about an hour ago at 2:30, it rebooted again, with no overheating or any other problems.
I'm at a loss about what could be causing this. I uninstalled Astrid To-Do app completely now, but I'll have to wait to make sure that fixed anything. I have about 7 days left before my 30 day return policy kicks in, but I moved to Boston from Iowa to go to college, and I would have to mail it back, which I would prefer not to do (cost and time without a phone being the major issues).
I'm running:
Firmware 2.1-update1
Baseband version 2.05.10.06.29
Kernel version 2.6.29-e9066436

A cell phone is a transmitter just like a radio tower, and higher power is required to send the signal farther. Every modern cell phone automatically adjusts its transmitter power based on reception. Fewer bars means faster battery drain when you are using your phone. Switching to 2G will not necessarily save battery. If you have a 3G tower nearby, then your battery will last longer. And if you have a spotty 4G connection, you'd best plug in, or don't use it. However, given equal signal strength, a 4G signal is MORE efficient per byte than 3G.

Is it me or anyone else experiencing the rapid drain of battery after the recent OTA update from T Mobile for the Vibrant. Prior to the OTA update, my Vibrant charge used to last 2-3 days of normal use before I had to charge. Now the battery life is considerably shortened and from 100%, it goes to below 20% in 12-15 hrs, most of it is idle time. My normal usage has not changed at all before and after the update but I am experiencing this rapid battery drain phenomenon on my Vibrant.

About a week ago, at random times, my Incredible will become "Incredibly" hot in my pocket, and the battery begins to drain at a rapid rate (from nearly 90%+ to <20% in an hour).This seems to be accompanied by an icon resembling a "refresh" symbol at the top of the screen (a circle consisting of two arrows).I can't determine any common denominator as to when this takes place, it seems pretty random.I added Google voice and Shazam to my phone just prior to this problem beginning, but have noticed no usage relation. Please feel free to direct me to another thread / lock if this has already been discussed.

My Eris, just updated on Monday for the lock up from sleep Anyway, I am a low user of the phone and keep, wifi, Mobile data off unless I am using it I have noticed the last 2 days the battery life is improved. yesterday, phone on at 6am off at 11pm, 65% left, no data used, few Txt messages and about 45 min of phone calls Today so far, on at 6am, WIFI, Mobile data off, one 6min call and one txt, at 9am, still 100% battery. turned Mobile Data on at 9am now it is 11:50am and battery is still 100% my on time is 5:45, awake time is 8 min (2%) this is typical for me. I don't have email set to push, I refresh when I want it. I also use Advanced Task Manager. So maybe the issue that was fixed was also causing a battery drain and is fixed now?

So I have had my phone since before launch and I have noticed the battery drain as others have but here is my question. Do you think it is the battery or the phone?
If I can go to the store and just get a new battery that would be nice because I have rooted and customized and downloaded apps and if it is the battery that is causing the problem it would be so much more convenient to get a new battery.
