Samsung Captivate :: Phone Never Sleeps - Battery Dead By The End Of The Day
Nov 15, 2010
I haven't been getting very good battery life (less than one day with VERY minimal actual use). I installed Android System Info and went to DashBoard, then Battery, then History. If I select "Other usage" and "Since last unplugged" it shows "Running" as 100%. When I click on the "Running" bar it says "Time spent without sleeping: 14h 43m 15s (100%)". So it looks like it hasn't gone to sleep at all since I unplugged it.
7 of those 14+ hours was spent sitting on my desk at work and 90% or more of the rest of the time was spent either in my jacket pocket or sitting on the table at home. I spent maybe 30 mins reading texts and browsing the market and didn't do anything else with the phone all day.
Should it not have gone to sleep for at least some of that time? Could this be why the battery is pretty much dead by the end of the day? Is there a way to figure out why it's not going to sleep at all?

I have a sprint GNex. I just started having this problem recently (but before the 4.3 update). I plug my phone in overnight and at some point in the middle of the night an error occurs that make the phone think it is off the charger and has a fully depleted battery. The battery level icon shows no charge and if I pull the phone off the charger it immediately says it has to shut down due to a low battery. However, as soon as I turn it back on it is back to normal with a full charge.

I had flashed my mobile to I7500XEFJB2 yesterday. Thanks to the wonderful instructions from most of you folks that actually made this possible!!
However, One thing i observed ever since i had installed this firmware is the phone is awake 100% of the time and never has gone to sleep when checked in "Spareparts" .
The only apps i had actually installed were GOGGLES, Advanced task manager, Seesmic for twitter, Google Voice, Advanced task killer. Now i have actually uninstalled GOGGLES, Advanced task manager to check if they were keeping my phone awake (will revert back if this shows improvement ).

My Samsung Galaxy S2's battery went dead because I didn't charge it when it was down! The first times I tried turning it on it turned on and off almost instantly once it had got to the lock. Now it just vibrates (does this when you turn on) and does nothing.

When I got home from work today my battery was down to 20%. I plugged the charger in then started messing around on youtube. An hour later my phone shuts off and wouldn't power back on. Red led was blinking for about five minutes then the phone powered itself back on. I checked osmonitor and it showed my battery at 0% and battery temp at 140f. Will the battery not charge if your using this phone or is my charger bad?

From what I can tell, if you turn on WiFi the phone never sleeps even in standby mode. Is this a known issue or has anyone else noticed this. I noticed this using Spare Parts and turning off and on things until I saw it was wifi that keeps it awake.

I'm not sure if this is an android problem, or a samsung i9000 problem, but either way it's an annoying problem that I'd love to find a solution for ?_? I simply cant get the alarm to work for me (overnight. it's fine in the very short term). It appears to be because the clock stops moving/updating when the phone goes to sleep, because when I turn the screen back on I can see that the time is off by multiple hours, depending upon when it stopped updating, and stays that way for a couple of seconds before changing to the correct time.
Things to note here..
I do NOT use a task killer
The alarm volume is up
I have tried the alarm both with and without the Automatic, network provided time setting. The clock still stops moving. I've not updated anything from the standard (UK) firmware

The AT&T manual advises you to fully charge your battery when you get it while samsung tells you what I have always heard, which is to fully drain and recharge the battery when you first get the phone. This is what I have always done. Is fully discharging and then recharging the right thing to do? I would assume so, but I want to hear it from you guys.
Second. After the problem, I have become damn near paranoid on charging the phone. Since the purchase I ran it down completely until the phone shut itself down. I then fully charged the phone in one sitting. Am I now free to plug and pull when I need to? Should I do a couple more full cycles? God, this all sounds silly even while typing this..lol, but I have been sitting it opposite rooms because I am afraid to move the phone and break the charge...lol. God...I feel dumb. Don't laugh too much...Maybe I am?

Since I got my Captivate just a couple of weeks after it hit the market, I experienced really good battery life. I could plug the charger in at 6:00 when I get up, take it off the charger at 7:30 when I leave for work, and make it til the next morning most days.A couple of weeks ago, I left for work with a full charge, and around 11:00 I took out my phone to test WiFi coverage for some new access points we had installed in the office. The phone felt very warm, and the battery indicator was yellow. For the next couple of days it went like this. I had a spare Samsung battery from when AT&T sent us a new one for my wife's Captivate when she was having random shutdown issues, so I swapped batteries. Things were fine for 10-11 days. Then suddenly last evening about 7:30, when I went to look something up online with my phone, it was very warm again, and the battery indicator was red. Had to put it on the car charger when I left church.When I got home, I put it on the charger all night. By midday today, it was in the yellow, and it finally died about an hour ago. again the handset felt very warm. I don't have a spare USB cable here at work, so will have to wait to get home to charge it. Anything particular I should look for on the phone (running apps, etc.)? Or do I just need to go ahead and place a call to AT&T support?

For any android phone. How should one use/ charge the phone when it's new?
I know that With the nexus one, people are told to fully charge the phone for an amount of time before even turning on the phone.
Once I get my samsung captivate should I do the same or something different?

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.

So after flashing to the JH2 firmware, I noticed that the battery is reaching high temperatures during voice calls - Before the firmware flash, the phone would not get above 100 degrees during a voice call. After 8 minutes on a voice call, the phone is reaching upwards of 110 degrees.

So I painfully watched my Cappy's battery door crushed under my friend's car as one of their "harmless" joke. Now there's not a single site on the internet selling these doors, and I'm desperate. I found dummy/display Captivates though, so I was just wondering if anyone knows if the dummy battery door can replace the REAL door by any chance?

I just got my new Samsung i7500 Galaxy and try to connect to the PC, First my NPS rel 1.2.0 did not accept the phone, I could see it, I could se virtual disk, but not connet to the phone , NPS said "Not supported phone", I went to Update NPS, and NPS found rel 1.3.0. IJ1 which I downloaded and installed. Then phone still not connected. NPS displayed message- "this firmware not supported, only supported function is upgrading firmware", well that was easy :-) go to update in NPS, found new firmware version, and NPS downloaded, copied the old version from the phone to PC, and then uploading new firmware, it went all the way on the PC to 100%! and Success - completed.
However Display on Phone is still showing " Downloading..." and show a blue square icon in display, after 2 hours I took the battery out for 5 minutes and put it back in, and the phone goes back to "downloading " -
I have tried to :
Power off Hold volume down + call button + end call button and Volume down + OK (center of d pad)) + power
But this just "lock the phone in a mode with display off".
Any Ideas on how to reset the phone and start on again ? Do I have to turn it in to Samsung?

Up time & awake time are always the same, even when phone sits for hours untouched. "Data Always On" is checked off.

I have a Star A3 running 2.3.4
I am running Ttorrent Pro on the phone, and the speeds are less than impressive (everyone else says the same thing) I am on a very fast connection, using speed guide I literally max out the speedtest servers in my local area (20Mb up/down which is the max they let you go to, I would get 100/100 if my speedtest server would allow it) and I have a port forwarded correctly.
but anyways, what I have noticed is, when wake the phone, and open the torrent application the speeds are down to around 3Kbps if I leave it open the speeds immediately start ramping up to 200-300Kbps if I keep it awake.
So this makes me think, when the phone is sleeping a lot of the connections are being closed, or when the phone is asleep it won't try and open new connections to new peers (and the current peer list may go stale while its asleep)
this is with all torrents, now the exact same torrent on another PC with a DSL connection (3Mb down 300Kb up) is downloading faster than the phone.
Are there any developers out there than can explain what processes are going to sleep that may be useful to keep awake for downloading, and also what are the tcp limits on the phone, ie. max open connections, max half open etc?

I was proud of my battery having lasted me close to 16 hrs yesterday. This morning, as a part of my daily routine of exploring appbrain, I installed astro and Weather Forecast&Clock Widget. I got busy with meetings and got back to my phone after 3 hrs to find it at 25% charge. Within the next few mins. it went to 0% and now dead. I didn't have time to see if the google sync was causing this....Have any of you had a problem with these two apps hogging battery ? Or thoughts on other possibilities ?

I just bought a second hand Samsung Galaxy Portal, and it's a great phone and works fine, but the battery is dead 12 hours after a full charge. I had a task killer installed at first but I removed it after reading about how it drains the battery, so I'm wondering what else it could be? I know it might just be an old battery that's lost it's will to hold charge, but what can I check on the phone before I have to splash out on a battery or take the phone back? I know it has some decent tools for monitoring battery usage so what should I be looking for?

Since day 1 my battery has never lasted no more than 4hours so I decided to download Advance Task Killer (Safe mode) and changed the setting on what apps i wanted to sync (email,news etc.) at what time! Now, I can get atleast eight hours intill my battery needs charge again! Just a FYI guys.

I am having issues.
So far, I have:
-Lowered the brightness all the way
-Taken the Sync off
-Turned off GPS/WiFi/Bluetooth
-Let battery drain all the way down and then charge it.
Still, however, my battery is draining very quickly with moderate use. In fact, when it is in standby and locked (screen off, no activity), it still drains at an incredible rate.
Is my battery fried?

My phones battery died last night and now my phone can do almost nothing. It will turn on but I have no signal just a x and anytime I try to use almost anything I get a force close error. Everything from trying to dial a number to opening google maps. It seems like almost everything included with the phone will not work. I tried a couple of games just to check and they seem to work ok. Does anyone know how to get my phone working again or if a reset will fix this, or do I need to take it to Sprint? My phone is not rooted and has died before with no ill effects.

Anyone else get an Incredible through the mail from Verizon that arrived with a dead battery? And by "dead" I mean that it will not take a charge. Mine arrived yesterday. I plugged in the battery and started to get to know the phone. After 10 minutes or so, I got the "plug in" message. Well, by the time I got the charger cord ready, the phone had shut off. That was 18 hours ago. It's been on the AC charger since then, but the phone will not power on. I'm HOPING it's the battery.

I previously had my gchat setup to be online all the time.. for some reason, I get logged off when my phone sleeps, or within a short preiod of time after my phone sleeps. I also do not get email notifications when the screen is off. I have to unlock the screen to get my updates now. Any idea how to change this back?I was also wondering about how to change the frequency of checking email and other updates, etc. to save some battery life

Is it just me or does it seem like your phone misses more than just an occasional notification for things like google voice, gmail or various small items while the phone is asleep? For some reason my phone will be asleep for just a short time, then I click to wake it up and my notification shows up then, but if I hadnt woke the phone up it wouldnt alert me even though its set to check and notify. This happening to anyone else?

There was another thread about this posted already but it had no poll!! Here's another with an actual poll. I hope this helps all of us get an idea of what kind of battery life to expect with the STOCK 1300mah battery.

For 2 days my battery has been draining quickly. This morning it is dead in less than 4 hours. I sent four texts. Checking battery usage, this is what I found: com.android.launcher - 46%, Beautiful Widget (just uninstalled) - 37%. I have never noticed these processes taking up so much battery. Background: I have been receiving a low storage notice so I deleted some apps, texts and pictures and plugged in for the night. The next morning the severe battery drain began. I was concerned about shorter battery life after the latest update so I have recently changed my settings to lower frequency for refreshing email, etc.
