HTC EVO 4G : Will Being In No Service Area Drain The Battery Faster
Jun 7, 2010
I started a new job today, the training room somehow manages to get no service. My phone died in about 7 hours, I used it for about 10 mins total.
All weekend I got much better results, with it coming in and out of service do you think it's draining it faster? Only thing I had turned on was gps location. I would like to keep it on so I don't have to power it up on breaks and wait for any missed messages to come through.

i've just flash a new miui rom on my o2x. and i found that the battery drain much faster than it was before. last night i had 14% of battery left on my phone, and this morning it shut down due to out of battery. so i pluged in my wall charger while my phone was off. and when it showed the green fully chargeed bar i disconnected the charger and boot my phone in to CWM recovery to wipe battery stats. then i reboot the phone into android and u know what? the phone show 100% of battery only in 3 secconds and then it show 1% left. i connect the charger and the phone show that it's being charged? how can it charge a fully charged battery? and the charging speed is faster as light. it's has been charging about 15 mins now and it show 46% charged. may be google was wrong saying that batterystats.bin does not affect the measurement of battery level.

Since updating google maps last Friday, my GPS icon goes on all the time and my battery seems to drain faster. I cannot shut it off except to cycle the power on my phone. Anyone else notice this?

After updating my Hero the other day I have noticed a marked decrease in battery life. This started the very next day after updating my hero.
Right now I'm at 41% of battery life left after unplugging from the charger about 9 hours ago. For the past few weeks, I have been around 65%-70% at this time of day, and I'd normally be at about 15%-20% at 10:30 when I go to bed.
Is anyone else experiencing a similar decrease in battery life after the update?

I will create a service to do something when some hot situation occurs.
By hot situation I mean:
the GPS/cell coordinates are in known zone;
known Bluetooth device detected;
known Wi-Fi network detected;
weather info has change;
considerable movement speed change detected: eg. from walking to travel by car.
As you see these tasks are heavy, and will be run frequently. 15 mins, but sometimes even more, when I have to detect the movement speed of the device.
The question I have, will this drain the battery heavily?
If so, what recommendations do you have to minimize battery drain with the above tasks?

According to a forum post on Android Central, the Sprint Epic 4G has been experiencing battery drain due to a DRM service running in the background that the Captivate also has. They say, kill the service, save your battery:

I got CL14 on the 19th after having my moment for a couple months they fixed the battery gauge! However, I got a new issue with CL14. I work at a job that is in a bomb proof area. I have always left my phone on in the area even though I usually get no service, sometimes one bar.
The reason I leave the phone on is because sometimes I am in there for 2 minutes, sometimes for 3 hours between breaks so with the long boot times it sucks turning on and off and and off (especially if I am only in there a minute). I also cant switch it off while I am in there since I would get in trouble for taking it out of my pocket.
Eveything had been fine until CL14, now when I go into that room with little service after about 1-2 hours the phone battery it totally dead. The phone is very hot to the touch as well. at first i though it was the screen was somehow on, but I have been checking it every few minutes and its not. Basically my hunch is something changed in the CPU usage when the phone is searching for service with the CL14 update that causes the battery to run out of juice (for real this time) very very fast. Any setting I can change? Most regular cells go into a "power save" mode when there is no service, the moment does not.
Cliff notes:
Cl05, battery gauge, but no problem for months at my work with no service.
CL14 installed now battery is being completely drained from full to shut down in 1-2 hours, in low/no service areas, phone getting very hot.

I've had an ongoing struggle with my X's battery life, from day 1 with 2 different standard batteries to try until now with the extended battery.
I've tried it all and thensome and nothing has majorly improved my battery life. I won't go into number of hours I get or usage details or anything, but I have a question I cannot seem to find any solution to.
I noticed after I updated to leaked 2.2 Froyo that very often the 3g up and download arrows are both lit up and basically never turn off. After a few days of trying to figure out what it was (and using Juice Defender in the meantime to shut data off except for 15 min intervals), I think I've figured out what is causing the 3g data to often constantly be transmitting.
I went into the Battery History screen, left it set to "Since last unplugged" and went to "Network usage". In here, the bar for "UID 10012" is very high, almost all blue. Every time I exit the menu and go back into to re-check those data numbers, they are always increased after only seconds while the 3g data symbol is active.
Inside of the details for that are several built-in system app names. I tried stopping a few of these through the Applications menu of the phone where you can stop services/apps.
I finally have force stopped one (has worked several times now) that has stopped the 3g data instantly every time.
This one is "Social Messaging Service".
Every time I click the "Force stop" button within that app's info page in the Application settings of the phone, the 3g data arrows stop lighting up instantly.
Is this app related only to the Social Networking built-in app (which I don't use/need)? Is it tied to other things? Is there a downside to me stopping this?
I can't seem to keep it stopped and it seems to cause this 3g data issue every day at some time (multiple times usually - seems to happen again a few hours after I've stopped it). I think it is attributing to my sometimes bad battery life.
How can I stop this ongoing Social Messaging "bug" battery drain?

Is there any way to disable this app and keep it from restarting?? It is a serious battery killer. I go into the "running apps" menu and kill it, but it soon starts back up. Can I uninstall this? Or isit one that came with the telephone and can't be removedunless rooted?

What is weird to me is that on the closeup line graph the second half plummets much faster than the first half. But at the same time, the second half doesn't nearly have as many wakelocks (as indicated by the "Awake" bar being basically completely empty during that time.
What the mobile network colours represent but I never had this problem previously with it on all the time so this shouldn't be an issue. GPS is always on. Again, this was never an issue until supposedly now so this also shouldn't be an issue.
Now, the four big drainers are Cell Standby, Android System, Google Services, and Android OS. Cell Standby I know is due to a missplaced decimal point in the framework, so I know that's just false battery recording. Android System I don't have a clue what the problem is, I read somewhere it might have to deal with wakelocks. But it won't tell me what process exactly is causing battery drain. Google Services are well, google services. I don't know what are classified as google services exactly (like this was never a problem before..), and finally Android OS. Again, the battery statistics thing isn't nearly specific enough.

My droid x signal pretty much always between -92dBm and -87dBm with 1-3 3g bars. My former droid eris would get -92dBm with 1 bar and also drain incredibly fast.
On the droid x, if I go into google maps, the circle of the cell tower appears and the place I live at is half way within the edge of the circle and the other half is outside of the circle. I always seem to be connected to this tower. Bad luck I guess that I'm on the outskirts of the circle.
Does anyone know how cell towers are distributed? Do they overlap sometimes?
I run pandora with the screen off for a half hour with the screen off and my battery is down to 70%. I have about 15% screen brightness and battery saving mode on.
yesterday, I was on meebo for an hour and 45 minutes and it was down to 60% from a full charge.

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?

Has anyone noticed an increase in battey drain while using the Lookout Mobile Security app? I noticed my battery drain was a little higher than usual today. I also have an app called battery indicator installed and was wondering if those apps cause higher battery drain also?

Rooted Droid 1, running LFY 1.9 with it's 1ghz kernel, SPRecovery. Had a weird issue recently; the phone displayed that my battery life was at 40%, then probably ~30 minutes later it was down to 20%. I wasn't using it during that time, I just unlocked the screen to check something. Anyway, I opened my browser and within a minute or two I got the "15% battery life remaining" message, prompting me to connect my charger. I decided I would allow the phone to just die and shut itself down. So I waited ~45 minutes and it went down to 10%, then almost immediately to 5%. I turned on the GPS just to make it drain faster... I watched a one-hour television show and when it was over, I glanced over to the phone to see if it had died - nope, still on. I turned the LED light on, leaving the GPS running for ~25 minutes and it finally powered down. Then I plugged it in to charge and left the room. Came back in about 2.5 hours later and picked up the phone - it was very hot. Unlocked the screen and checked SetCPU and it was running ~135?F but it immediately started cooling down. It was fully charged, however so I unplugged it. I went to bed shortly thereafter and the battery life displayed 90% as I set the alarm to wake me up the next morning. I happened to wake up shortly before the alarm was set to go off and I picked up the phone to disable the alarm and noticed the red 'charge me' light blinking - unlocked the screen to see 5% and just then it powered itself down.
TL;DR -- Phone only got hot that one time, phone hasn't gone dead in stand-by mode again like it did that night. Battery drains at a seemingly normal rate based on my regular use from 100% down to 40%, then it rapidly drains after that, always skipping 30% and when it gets down to 5% it stays alive for quite a long time under heavy load. Is there a way to 'teach' the phone how to check and calculate actual and remaining battery % and to display it correctly? Is it kernel-related? I heard somewhere about doing a 'battery wipe' but I am unsure what that entails and searches are proving fruitless for me so far.

I have a Motorola Milestone with Android 2.1. I'd like an app which shows the battery level in the notification bar. Nothing fancy, no estimation of remaining battery life nor fancy eye candy. If it can show a more precise reading than the Milestone built-in one, which only decreases in 10% intervals, fine, but only if this isn't a drain on the battery. I know there are several such apps, but which do you think is the best for my needs? There are so many it's hard to try them all and choose. I just want something basic and simple which doesn't drain the battery. I tried "battery indicator" and "battery status pro"; they both do what I need, but I'm afraid they might be an additional drain on the battery.

Is there a significant difference in time needed for sending data over a service or by using an intent?
Are there general advices when to use service and when to use intents?

My wife's phone has used almost 4GB of data this month and her battery has been draining much faster than mine, especially at night. Last night we watched in SystemPanel at the Net Receive indicator and it was constantly downloading at least 200+ kps. I had read about some issues with Facebook so we removed the Friendstream widget and saw the downloading go close to zero.
This morning, I checked the 8 hour monitoring in SystemPanel and saw that the CPU activity was still high overnight (running near 30%) and her battery drain was twice mine (over 13% used over ~7 hours, mine was around 5% drain).
I loaded up Spare Parts on her phone and was looked under Battery History, Network Usage and took this picture (sorry about the quality, her screen protector makes it hard to get a good picture and she is not rooted). Can anyone explain what UID 10006 is and why it is downloading so much data? I do not see it listed on my phone in Spare Parts. What do we need to do to turn this off or at least slow it down?

For some reason my battery is draining a lot faster all of a sudden. I went from losing about 6% battery over night to 20%. Can't figure it out. I deleted the most recent apps, turn off 3g and all that. I checked my running services and nothing changed.

Basically, if i play any games for about 10 minutes the phone gets hot. Not like a boiling, burn your fingers hot, but hot enough to cause the phone to power off/restart. It gets hot from general use too, browsing the internet and such. This cant be normal can it? Its getting hot under the battery near the sim card, and the front of the phone gets hot too. I know this may have been posted before but i looked at the other threads suggested about overheating and they didn't apply.

My battery charges 2x faster now than before the update last week. Today I when I got off work, my battery was at 30% (lots of usage during and work in a plant). I put my phone on the charger at 5:30 pm. It's now 6:34 pm and my battery is at 98% charged. I'm using the standard charge provided by HTC.

I installed the Missed Reminder app on my phone this weekend but I've read around here that this is a big battery drain program. By navigating to the Battery usage section within the Android settings, the Missed Reminder app doesn't even show up. Does this mean the app is NOT draining, or am I looking in the wrong area?

Well, its been about 32 hours with my EVO...and im loving it.
I admit, the battery worries me a bit. However, some commonsense things (and not so common sense, like the GSM/CDMA battery life change) have really helped. Task Manager seems to be the best overall task killer app, and keeping background data on but auto sync off seems to be a nice happy medium for syncing.
The major, MAJOR battery drainer? Google Maps/Navigation. The perfect argument for a car charger that can EVER be made. Ye gods.
So I unplugged it from my charger at 11 this morning. As of right now at 6:43 pm i have 41% battery left, have been fiddling with it for about half of that time, and turned disabled the data connection while i was in low signal areas during a short road trip.
Moderate use of Yahoo Messenger, texting, a few 5 minute phone calls, the occasional manual update of the Seesmic twitter client and a few other things have drained it a little bit...but a 5 minute stretch of Google Navigation? Did the most damage to the battery, knocked it down by 7 percent. Again...car charger. Need this soon. Anyone know of any reliable ones?
Other than that, great phone. Versatile, and I'm looking forward to the day that Android 2.2 comes to us for even more battery efficiency. Please feel free to ask me anything about how I have things set up, constantly trying new things out on this!

So, i have tried most of the battery fixes on the forums, but my battery drains super fast. disabled talk, did the cdma fix, closed all possible running apps, turned off autosync and the battery still drains. It drained 35% in 30 minutes on airplane mode. I have the battery indicator app installed and the current temp is almost 45 celsius. Is this too hot? My phone is currently charging.

I know that this has been covered numerous times, under numerous various situations, but I am hoping I just missed something.I've had my Evo for about 2.5 weeks now, and love everything about it, except the battery (obviously). I expected about the amount of battery drain that I'm seeing from day 1, but the thing is, with all things equal, I was getting better battery a week ago.Basically, I followed several forums and tips that help to alleviate battery drain. I turned things off, tweaked update freqencies and other settings. I conditioned the battery in the manner that was suggested by HTC as well. After doing this, I was getting about 22-24 hours of battery with normal daily usage.All of a sudden, about 7 days ago, I went from 22-24 hours to about 10-12 (if I'm lucky). I realize that adding certain apps can cause things to go awry, however, I have deleted everything I had installed since realizing the excessive battery drain and I'm still getting drain. At times it appears that the phone isn't sleeping, however, when I look in settings, it's difficult to tell what is keeping it awake.Normally , this wouldn't bother me, because I kind of expect this kind of battery life, however, knowing that I can easily acheive 20 hours and not getting it is killing me.

If I have Gmail set to autosync, but have 3G (and WiFi and 4G) turned off, does this drain the battery when it tries to sync, or does it just not sync? I'd rather not have to manually turn off all syncing when I want to go off the network for a while.
