Battery near-empty after flying!? - Legend General

Hello clever people,
Having recently travelled, I've found that my Legend's battery tends to drain rapidly while on the plane even though the phone is completely switched off. For example, flying for 10 straight hours with the phone shut off, it went from approx. 95 % to 10 %. It doesn't drain anything like that when I'm using it normally for 10 hours. I'm baffled (and annoyed): how can this happen?

are you really sure that your phone was turned off? Why would it only be the legend that is suffering this? I flew a lot (not yet with my legend) and never noticed anything about the battery.

It would make sense if you phone was on as it would be continally scanning for a signal

Thanks for replying. Yes I'm positive it was fully turned off - or at least appeared to be (you know, after holding down the top button and choosing 'sluk' - Danish for 'shut down' - in the top of the menu, after which the phone is off and needs holding down the top button for restarting, featuring HTC logo, startup sound, pin code request etc.). But as you suggest, it might not be off afterall - why else would it drain the battery? Indeed, that's exactly why I'm baffled. Now I regret I didn't try taking out the battery.. Anyway, it shouldn't be necessary, this never happened with other phones.
Best, Sune.

I had a Touch Pro 2 and on some flights around Thailand it kept switching on during take off. It was having problems on the islands too and I ended up putting it down to humidity seeing as it works fine in Europe and Australia.
Don't no if this is connected or not.

Random Shutdown

When my phone is sitting idle (screen off) it will randomly decide to power itself off. Has anyone else noticed this? Any ideas on what could be causing it?

you mean randomly power itself ON, right?
if that is the case, it's normal, it just mean it woke up to connect to the internet, to get updates of news, emails, or whatever it was scheduled to pick up
nope. i mean it randomly turns itself off. this topic is being discussed over on the att captivate galaxy forum section.
interesting, so it's going from stanby mode, to complete OFF... nope never seen that happen to my i9000 model
yep totally powered off... completely sucks... looks like there are a bunch of ppl that have this issue with the captivate on att. $10 says its some lame piece of software that att puts on your phone that's causing the problem.
it's possible, i've read here a few users having crazy power issues (battery draining very fast) with their SGS i9000, but after wiping it out clean, to start anew, then the power problem is gone away.
so yes, a software could cause something weird like that.
Factory reset and so far so good
Hey guys,
I use a Galaxy S here in Hong Kong and I had the same random shut down issue constantly happen when my screen went off...
I tried everything, check temperature of cpu, etc. etc. and nothing worked, it just got worse and worse.
I even changed the battery to use the spare one that came with this. Still problematic.
Used SET CPU to limit the cpu to 400mhz, still problems.
Finally I did a factory reset and so far so good.
I only have the original system installed with the Remember the Milk app installed.
24 hours, no problems.
Installed AppBrain app.
Then I installed 3G WatchDog
12 hours, no problem.
Then I installed Paperdroid
12 hours, so far no problems at all.
If I run into an issue I'll post it here. But I think it definitely was a software issue.
Update - it randomly shut down on me
Alright guys, it shut down on my randomly today in the afternoon......
I dont know if it's the re-charging that screwed it up?
Because after my factory reset, last night was the first time i charged it....
Hmmm
This happened to me too - two days in a row until noon it would shut down two or three times - i uninstalled SetCpu and for now (24 hours) it hasn't happened again. I am not sure if it was the one responsible but it started happening after i installed two programs and i uninstalled them after it started happening. I uninstalled Visual Task Switcher first but on the next day it turned off again, then i unsinstalled SetCpu and it hasn't happened again - maybe some wrong profile settings but i didn't feel like experimenting
I had this issue once too in about 40 days.
I was reading an sms and then i turned into standby and put it in my pocket. Later, maybe 40 minutes i came home and my phone was completely off. I do not remember if i had to take out the battery before to get it on again.
I was wondering why it happened. Maybe it was caused by an app i had opened. Battery still was at 40%.
But since it only occured once in 40 days i doesn´t bother me.
Interesting you mention this as it just happened to me today for the first time. I took it out of my pocket and wtf? The phone was off. Very strange... Using the i9000 on the stock Eclair rom.
Should send back for warranty

software clash?
Well the phone suddenly switched off for me, but this time I turned off APPBRAIN and so far so good.
In fact, I came across an app called NoLED and since it kind of keeps ht phone on, while I have it on my desk, I'm able to be notified of stuff and so far with that, the phone hasnt' shut off.
I'm still experimenting with what works, but try turning off AppBrain and see if you still have the random shut off issue....
i use app brain all the time to keep my apps in sync
not the cause of the problem, that's for sure
my phone can last a whole day even with app brain running
OP, do you have MSN Talk installed on your phone? I have this same problem, seems to happen more when I am running MSN talk in a low signal area.
«try a new sim card. «Could be faulty. «i am on my 3rd phone and all of them had this same problem. «i bought a new sim card 4 days ago, and hasnt happened since. «but then again, this problem usually happens to me once every 3rd-5th day anyways, so i dont know if i am in the clear yet.
Me too, shutdown everyday
Hi guys
After upgrade OS to I9000ZSJG4, Phone random shutdown everyday.
Yep still shuts down
Tried keeping AppBrain off, still shuts down.
Used NoLED so the screen kind of stays on, still shuts off..
So far shut off on me after 40 hrs... this is really stupid.
I am this close to taking it back, but I genuinely think it's a software issue than a hardware issue...sigh
Anyone have any luck figuring this out?
Same problem no solution yet
Hi
I too have the same problem, haven't found any solution yet.
The temperature etc is all good, there is no pattern in shutdown issues.
I have tried factory reset and no new application, it still shut down while using in built browser.
I had the same thing happen to me while skiing in Whistler last weekend. It died twice. I attributed it to the cold. I normally use a 3000mah battery up there, but left it back the house that day. Afterwards while charging in the car and even charging it at home it died prematurely again. It was the eBay aftermarket variety 1500mah knock off. I have since changed back to the Samsung OEM battery. I haven't had an issue with it since. My assumption is that the knock offs in my case cannot handle the heat cycles of charging and then the cold as well as the original. Or they have a limited lifespan, well below OEM specs. I am now only using the 3000mah battery on the weekends to hedge my bet on the quality of manufacture, as it seems to be from the same factory as the 1500.

Has this ever happened to you?...Vibrant seems dead, battey re-install needed!

Since I have got it (2 weeks ago) i have picked up my phone make a call, and on about 7-8 occasions, have noticed that the phone is turned off, and I can't get it to turn on. The only solution is to take out the battery and put it back in. Has anyone else experienced this. I have updated to JH2 firmware, but it still happens. I even got a new battery for the phone (Bell employee let me swap with another phone that was going back to samsung for gps issues), but the problem still happens once in awhile (like every 2 days, sometimes more sometimes less). Anyone have any ideas? thanks
UPDATE: Someone mentioned for me to call my phone the next time this happens to see if it rings. They said it might stuck in sleep mode? Not sure, i just pullthe battery and then it works
I've had this happen, but only when the GPS was on. If it's happening with the GPS off, I'm guessing you've got a lemon.
So far I've not needed to take the battery out, though. I've always been able to reboot by holding the power button down for 5-10 seconds instead.
Yes I have been experiencing the same problem. From what I can see, it seems like the phone is over heating then it locks up. My only fix was to install a battery temperature monitor and also kill any tasks that are not needed by the phone. My phone hasn't locked like that since I've been doing that.

I have not had this problem. Been on a call for about 1-2 hours one time and the phone was fine. I was able to switch it to speaker, bluetooth, open other apps, and etc without any problems. I don't run task managers. I do have one, but I rarely use it.
Interesting...I experienced this for the first time today. Picked up my phone from teh night stand after having it plugged in all night and it was off. Had to pull the battery to get it to come on. The battery was about 85% charged when it came back on. It worked ok since but the battery drained kinda quick. I am using an aftermarket battery, got the 2 batts and charger on ebay. So I put the other battery in and havn't had any issues. I wonder if it over heated while charging? What apps are you guys running? The one I am running that would be most suspect would be weatherbug elite, and I just installed it a day or 2 before this happened.
I think it is a GPS issue. I got this phone on the first day of release. I’ve never had this problem until just days ago. I hadn't used the GPS extensively before last Thursday and Friday. During my business trip I had the GPS on for almost two days straight and during these two days I experienced the blank screen, shut down twice. I had to cycle the battery to get it to boot.
I had this happen to me while using Set CPU. Check out this thread. http :// forum.xda-developers.com/showthread.php?t=727006
take out spaces and what not.
I had this problem on my g1 but it started to get worst an I soon need too keep my mobile always connected to a charger so out turned into a landline phone lol but it was because I somehow broke a middle cell in my battery and need replacing but I don't know what to say about yours cause you tried a different battery :S

Experienced a freeze just a few hours ago while running the navigate application.
Trying to show my wife how uber cool it was and all. Switched on GPS, launched maps, chose directions, method / navigate. GPS locked and had my location pinned down until I reached the corner and suddenly the GPS kicked me to a location about 5 blocks away then froze the phone, requiring a battery pull and reboot.

Overheating and battery life.

I don't know what all your experiences are, but I noticed the past few days that my epic is getting hot on the back.
I also noticed that my battery is draining more so than usual. When I got the update last week my battery life sucked, but now since this overheat thing it's gotten worse. It drops a lot even when in standby.
I do not have gps, wifi, anything else on. I am not rooted. Didn't do any battery tweaks. This is completely stock di18.
This is normal use with 3g. It's getting annoying and I'm hoping someone has an answer. Thanks!
Do you have any email accounts configured in the mail application?
This happened once or twice - I rebooted the phone and all was peachy.
Sounds like you have a rogue process wearin it out.
Yeah my phone overheated yesterday while charging....this phone has a few more steps to go before it really beats my hero...

I partly found out what the problem was, but it seems you guys are ahead of me. I had some process keeping my CPU running at 95-100% nonstop. I still haven't figured out what the process was, as now it is back to the normal 5-15%, but I'll have to keep an eye on it now.
the task manager widget turns red and it shows you what process was causing it...for me it was the xda app...a few times.
I think my problem was not backing out of WordFeud. I didn't notice anything on the task manager though. Hasn't happened since that one time.
this happens to me when i'm plugged in and using gmail. screen flickers and then shuts off. the screen-off battery indicator shows the batt. gauge and a little thermometer sign next to it indicating it's too hot.
wtf?!?! this has to be a defect. anyway, is there any official word on this? any pr from sammy/sprint?
i have read elsewhere about some epics resetting themselves a few times a day which could indicate an issue with heating (at least on a pc). so if you think it might be hardware its possible. otherwise keep doing what your doing, monitor your processes for anything thats eating it up, go to about phone > battery use > cell standby to see your time without signal. the higher this is the more battery use. also, might want to consider a startup manager to prevent the 2 DRM files (search forums) from running as this can affect batt life too
you can also use setcpu even (free on here, search it) to throttle your cpu down when it hits a certain temp.
This is very interesting... My wife and I both have this phone, she has had this happen several times after the last update (I though she was just crazy). Me on the other hand... No problem!
I need to look into this a little deeper.
The only time my epic's battery gets hot is during heavy use or gps. Gps/Nav makes it heat up like a mofo. But other than that... *knocks on wood* Its all good, no problems. As far at battery life, I am rooted and using SetCPU to turn down the processor while the screen is off, helps a ton. Not using anything other than that... was using juicedefender but then I started not getting calls or text...

One thing, I learned, that didn't help my battery was putting my phone in the locker at work. That thing must have killed my TWS and ate my battery alive.
i feel like this thread will start to die but i had a weird somewhat related issue last night. i too have had maybe 3-4 times where i woke up to my charging phone with the red LED and a screen that would not turn on, battery pull, worked fine.
however, THIS morning my phone would freeze like 30 seconds after boot EVERY time. tried a few things to no avail until I wiped, reinstalled my ROM (aosp 0.4.1) and the data from a previous backup (which was the way i got that ROM to first boot successfully according to tips in that thread).
so this worked, but i couldnt figure out why my other steps wouldnt. had to be something in the data partition of my system at the time, since changing that worked. the only thing i could think of is that app watchdog which someone mentioned to track processor usage by apps. anyone else ever experience this?
I have experienced this once when I was playing Robodefense while the phone was charging. My phone tends to get a little warm when it charges, and hot if I run something intensive while its charging. Wondering if this will be an issue when I use this phone for GPS nav while plugged into my car.

"I'm having this problem too...I didn't get any warranty for this either. Any reasons onto why this is happening...I woke up this morning and picked up my burning phone lol the temp was at 50C so I took out the battery and let it sit for 15 mins...it went down to 30C, then after not touching it for another 15..it was at 17C...very odd...what should I do, this crap is going to die within the next hour I'm worried it will fry the hard drive or something. Need help! " - I wrote this on a diff. forum a couple days ago
I dont have anything on, no wifi, gps, or any 4g (lol only if I could find it)...I even got rid of my facebook/twitter/weather updater widgets. The only thing that updates is email, and that's only if I click on it. The battery has been dying a lot faster and I charge my phone next to the window now because its like 20 degrees outside here in Chicago, so that brings down my phones temp lol....and today, my phone's battery life went from 100 to 5 percent in about three hours of barely using it...wtf?!
Also, another problem...sometimes when I lock my phone and unlock it after taking it out my pocket or something, the screen doesn't seem to respond...I keep swiping my finger over it to put in my password and it wont do anything and it only works when I slide up my phone for the horizontal view. This happens like 4 out of every 10 times I open phone.
Very embarrassing especially if your trying to get someones number down, I stopped showing off the phone now ...lol

should i return this iconia?

Hello all,
I bought my iconia tab last Tues. I am a big fan of android. But I have used an I pad since they were released. Now I'm not going to make comparisons, but I'm thinking I may have received a bad unit. Or maybeothers can verify my findings.
Battery life is horrible.
I barely get 4 hours of use before I need to go running for the charger.
Random shutdowns and reboot.
Unit will shutdown at random, even when I'm using it. And it reboot any time it loses a wifi source. Ex. I have a mobile hotspot. If I shut the hotspot off, the iconia will reboot when it loses the signal.
Screen on/off all day.
When I put the unit in standby, the screen turns on and off about evey 2 minutes.
Laggy keyboard.
Even as I type this, the keyboard is extremly laggy.
I am running this unit stock now, nothing extra has been installed.
I even did a factory reset and hard reset.
Ii have not received any updates, although I check all the time. I'm still on the 1.104. Build.
Any suggestions? Thanks.
from your description, yeah, you should probably return this unit...
just return my device is not that bad, battery last 1 day with normal use, never random shut down
the only thing i got troubled with is screen on/off , that is solved by pressing powerr button several times, very annoying actuallly
I've gotten 2 days of moderate use, I usually charge every night but unless I'm playing games for hours at a time I'm usually @ 40% before I plug in.
If the tab is rebooting on a frequent basis, particularly if you can do it on demand, definitely return it.
The screen random on should be fixed by the .141 update
I don't want to start anything but when i read "Should I return it?" and your posting it in this forum, then most likely the person posting it (if you found this forum) knows a little about it. But to read, it shuts off, battery life is terrible, etc..
I dont use it all day but i will use it with lowest brightness, 1 min timeout, and i dont use twitter or play movies, but get like 5-8 days on a charge.. NOW, one key thing, i turn the power OFF when done using it and does hold the battery much better (I never tried airplane mode)..
Never mind, got off on a rant from the thread...unrelated, there are some very cool news apps that are out now for HC.
Ok. Returned it for a fresh unit. Letting it get a full charge before I do anything with it.
Fyi. Previous unit only gave me 4 hours. Regardless if I was using it or it was sitting in standby.
Does anyone know of a way to get the 141 update without rooting?

For the first time since I bought it I haven't used my device for a day. In around 22 hours of standby it lost 3% battery.
So draining in 4 hours in standby sounds completly defective to me.
when I got mine
battery was at 50%
I used it during the day, and when the battery was arround 5% I did a full charge
- regular usage : 1day ++
- working usage : 8 hours (web apps dev...)
4 hours, use it or not it's awfull...
Wish you got better now

What kind of screen problem? Is it turning on randomly while in stand by or the other way around, turning off while in use?
And for my future reference, how do you do returns in Indonesia? Do you take it to the store or to the service center (or either)? Thanks in advance!

Yes, the screen would randomy turn on/off while in standby.
The other. The tablet would actually power off while i was using it, not just th screen, the entire thing.

[Q] Battery Drain When Powered Off

Anyone else encountered this problem ?
I've had my Nexus 4 for 3 days now.
I turn my phone off every night. So two nights for this phone. Each time I have turned it off it has been fully charged, with the battery indicator and a third party app both showing 100 %. The next morning (about 8 hours later) I'm finding the battery has dropped to ~85%, so losing ~2% per hour when powered off.
Anyone else encountered this or know how to deal with it (before I contact Google)
Note - to power off I press the power stud until the Power Off menu appears, select Power Off, then click on OK to shut the phone down.
This is with Android 4.2.1
It takes power to turn the phone on. 15% might be a little much but it is not unlikely.

15% does sound a little high. OP, how's the battery life during daily/normal usage?

Battery life has actually been decent, I think I'm getting better usage than my old HTC Desire Z with extended battery. I'm not a heavy user, though I have been using it for music at work.

It takes a huge amount of battery power to start the phone from complete off, this also skews the first reading of the battery voltage as it will be lowered by the draw of power to start the phone so the indicator will read lower than it's true capacity.
The best solution is just put your phone in airplane mode at night, and turn airplane mode off in the morning, this is more power efficient than shutting the phone down using "power off", and you shouldn't see any battery drain apart from a percent or so doing this.
Regards
Phil
You can tell you guys never turn your phones off Starting up should have no battery drain - never been an issue on any of my previous phones and PDAs (last one also being Android).
I rang Google and they had never seen it before but recommended draining then fully charging the battery.
Friday night I made sur it was fully charged before unplugging and shutting down - next morning on turning on - 99% - result. Saturday/Sunday the same (note SAturday i fully drained then recharged the battery). This morning boots up with just 82%.
Looks like either it can't work out when it's fully charged, else there's some disharge mechanism in place to protect the battery and that's causing me issues.
It probably wasn't really at 100% even it was reporting as such. The reporting is broken. So when you rebooted you saw the real battery level.

I was just about to start a thread on this and then saw this thread here. So I'll ask here. I travel overseas a lot. So while I am on the plane I plug the phone in while off to charge it. I hit the power button occasionally to check the charge and when it shows "Full" I unplug it and throw it in my bag.
2 days later, I come back to the US and turn the phone on and the battery is usually below 50% even though it stated it was fully charged when I unplugged it.
So how does the battery drain if the phone is off?
I just sent my first Nexus 4 in for RMA on this very issue (if left for long enough it would just fully discharge), got the replacement on Friday, did a charge cycle, charged the phone fully up whilst off, took it off the charger (the official Nexus charger btw), and let it sit for the last day, just turned it on, and it's at 60%.... W T F !!!
This is sooo totally bizarre! I can only assume that this is common to most Nexus 4 (what are the odds of me getting two bad ones - direct from Google - with the exact the same issue?), and that people just aren't noticing, as most people don't leave their phones off after fully charging, and thus just never notice, as the battery behaves perfectly normally under usual use.
I would gratefully appreciate it if people could put this to the test, so I know whether or not to RMA the second device or not....

Are you using a custom rom, maybe its only sleeping.
Can't speak for the OP - but for me, no on both devices - totally stock. The latest one, box fresh on Friday! Also, the phone is most definitely OFF, and not just sleeping, ie, I press the power button & choose the "power off" option from the pop up. Unfortunately there's no way to really test this, by pulling the battery...

Nah - I tested it multiple times on my first phone. One time I left it for over two days and the battery went from "reporting 100%" to being under 10% whilst turned off!! Also on all the charges - I deliberately would leave the phone on the charger for multiple hours, even after it was reporting 100%, as I had the same suspicion. Often I'd leave it to charge overnight...
I have never had this issue with any other phone, or with my Nexus 7 (which I have subsequently tested in this respect, and it is perfectly capable of holding a charge whilst off)

It's not so much that it's a practical issue, it's more that I'm worried that it might indicative of a larger hardware based defect, and I'm not happy spending my hard earned cash on faulty goods.
If it's a very common complaint/fault then I won't bother to RMA the second one, but if I'm just ridiculously unlucky, and very few people are experiencing this totally weird behaviour, then I'll take my chances on a third...
Also, I don't think it's too much to ask to be able to turn my phone off to prevent it from losing any more charge. I can think of a plethora of scenarios where this would be extremely useful...
I'm now convinced of three things.
1. Android 4.2.1 can not properly read the battery state
2. Shutting down the phone does NOT do that, but rather puts it in to a hybernate mode that still requires battery charge
3. There is a fundamental design flaw in the phone that part causes this.
Most mornings I find my previously shut down at 100% charged phone at only 80-85%, though occasionally it is as high as 97-99, but not often.
Oh and my ROM is stock, my phone is not rooted.

I agree on all counts apart from the first, as my nexus 7 and my Mum's Nexus 10 behave totally normally in this respect, both on 4.2.1 and 4.2.2 (both stock/unrooted, although the Nexus 7 was rooted/bl-unlocked for a time).
Also, I don't believe it's a miss reading of the battery state, as I often leave the device charging for multiple hours after it reports 100%, by which point it simply must be fully charged. What's more - if you leave the device off for long enough it will fully discharge! The craziest thing is that the phone's battery seems to drain quicker when it's 'turned off", than when it's powered on and sleeping. Seriously WTF.
It must be something to do with either the LG hardware, or LG specific code in the Google ROM. Obviously the phone is incapable of properly shutting down, which is pretty crappy for a so called "flagship" device. As someone who likes to have full control of their device, I find it more than a wee bit irksome, that I don't have the ability to completely shutdown my phone! This is also where the irremovable battery is annoying, because there's no way to test whether it's a hardware or software issue, although I guess I could try a custom ROM and see if it still happens.... however I don't really wanna root & rom if I'm going to RMA it....
I'm really interested to know how many other people have this defect and don't even realise it, because their phone is either in use or charging! I find it hard to believe that I could be unlucky enough to have got two uniquely defective devices in a row...
I'd really appreciate it if people could check their devices for this issue, both on stock and custom ROMs, see if we can work out whether it's HW or SW related...

You could try powering it off with the bootloader. After you power off normally, hold power and volume down, when the bootloader menu comes on use volume keys to select power off and power button to confirm.
I'm hard pressed to believe the battery in my device would fully discharge if left off, when the phone arrived the battery wasn't dead, I got about three hours of solid tinkering before it died.

That's a good point. Mine came out of the box at about 80%.... hmmm. It could be that once it's first turned on it won't turn off again... this is such an odd issue! I shall try powering off from the bootloader next time, I'd still love to hear if other people's phones exhibit this anomaly though...
I'm aware that it's hard to believe issue, but there's only one way to find out...
I'm also very curious to know if loading a custom rom might solve it. I'm far less concerned if it's a software issue, I just don't want to have spend £250 on defective hardware.
I'm 100% stock, no Custom ROM nor kernal (kernel?) and my phone WILL discharge if left unplugged and "off". Happens every time I come back from overseas. Fully charge it up on the plane (even left the phone on but in airplane mode to 100% thinking that it was a misread of the battery level when the phone was "off") and still the same issue... turn it on a few days later and the charge is down to 75% or so....
I thought I was losing it... but I'm not the only one...

Ha - me too! With the first one, I actually went into a weird sort of denial, where I kept convincing myself that I must of got it wrong, it just seemed so absurd! Eventually I put it to the test (multiple times) and realized that my memory wasn't as bad as I'd been trying to persuade myself and the phone was in fact discharging when "off".
Anyone else?
Just got the update to 4.2.2 and have got my fingers firmly crossed that it's now a squished bug... although somehow I think it's more likely an LG/hardware issue...
What you could try to do it charge the battery to 100%, hold the power button for 10 seconds until it fully shuts itself off. Leave it overnight and see the battery level is at the next day.
