My LGOG E970 is overheating when I put it on my pocket and the battery is discharging very fast. Using the headphones I noticed that it was getting unlocked because it was dialing.
I configured pattern lock and the power button now instantly locks also quad core eco mode is on. However the phone still overheats.
I suspect that the power button is constantly pressed when in the pocket and the screen keeps turning on. This brings me to my question: Is there a way to use two button unlock on this device? Like pressing power and then volume up to turn the screen on.
Any suggestions?
Thanks.

Hello jaimesilva, saludos from a Venezolano.
I'm not aware of a two button unlock feature on the device. However, it shouldn't be overheating just because of having the screen on. I have used my phone for long times and it didn't overheat.
A few things to look at are: Applications, you could have a buggy app that is doing an intensive loop task that is draining and pushing your processor very hard.
Cell signal, check that you have good reception, sometimes when it finds a network but has trouble communicating to it, it falls into a loop of connecting/error. The other day I went to an indoor expo and it surprised me to see that in around 30 minutes it went from 60% to 30%, OVERHEATED too. I activated airplane mode and it stopped.
If nothing seems to fix it, do a factory reset, it will delete all your data and applications, backup everything and then start adding applications slowly day by day and you will be able to narrow it down to what app is causing it if the problem comes back. If not, it might be a defective unit.
Good luck.

Quite a few smartphones out there support hibernate. HTC is amongst the manufacturers that makes it possible to completely shutdown the phone and write all memory to a file on the nand which is put back in memory when the phone is turned back on. This way it only takes a few seconds to go from off to fully functioning, practically the same thing computers can do for years. Now I wonder if this could be done with the Defy (and possibly any other Android phone for that matter). I don't know how HTC does it but I guess it's pure software as in not an integrated Android feature. And if they can do it I'm sure some of the XDA guys can do it. Or is that wishful thinking??
Well if you want to save battery, then there are certain task killers which actually closes all the tasks which are not in use but running (excluding ignore list) and this way whenever the screen is turned off, it closes those tasks, that improves the battery. If that is what you meant?
I found this on google:
http://www.androidzoom.com/android_applications/tools/hibernate_ctp.html
No what I mean is in the event you have to shut down the phone entirely that all content in the RAM gets written to nand (or maybe sd). This way when it boots again it simply restores its RAM within seconds, effectively cutting boot time to only a few seconds instead of 40. Compare this with Windows' hibernate function for the pc.
Turns out HTC calls it Fast Boot. It's not a real hibernation function because if you put the phone to sleep with it and remove/replace the battery it would perform a normal cold boot. So it's more of a very low power sleep mode, guess more like a computer's S3 sleepstate where only the RAM stays powered while all the rest (cpu, chipset, video, audio etc) is turned off.
Sounds like a very interesting option, very curious if this would be possible on a defy.
This would be a nice feature.

Totally pointless if you ask me. Just enable airplane mode if you want epic battery life?

Or turn it all the way off and save even more power.
There are also plenty of 'smarter' ways to safe power, such as scheduling the handset to automatically disabling 3G overnight etc, which don't even require you to switch the handset off.
Airplane mode still leaves the cpu switched on. The purpose of that mode is to be still able to use the device without a working connection.
Say you are away from home and didn't bring the charger. Now the battery is almost dead. Then a very low power sleep mode would come in handy because it boots in only a few seconds and after a few more seconds you can turn it 'off' again. Fast and snappy, hardly using any power. And this is XDA so another extremely valid reason to have it is simply because we can. For pc's it's everyday technology so why not make it available on our pocket sized super computers?
I always disable hibernate in my PC.
Actually me too but I do use the sleep mode quite often with my laptop. Works great when you move your laptop a lot to other places but don't want long boot times. It could actually survive days in this mode on a full battery.
I'm getting a crash once every 3-4 days on average that requires a battery pull. So far I've had it happen while receiving a Whatsapp message, replying to a Google+ notification, and most recently, while listening to music.
I know I am not alone because I have seen a few other threads talking about similar issues. I am wondering how widespread this is however while I try to decide whether to return the phone or not. Are any of you running for a long period of time (1 week or more) without any instability?
I've had it happen to me a couple of times too, once when playing a movie in Diceplayer, and accidentally push the power button, causing the screen to go blank, then I couldn't turn it back on. Had to pull the battery. Had it happen to me again this morning, can't remember what I had done prior to it happening, though. Anyway, I did not have the time to pull the battery, so I just tried it again a couple of minutes later, and it woke up, all was normal again.
Happened twice only since November 25th to me.
I've had the phone now for a couple of weeks and have yet to have a crash.
My phone crashed two times in one week. Booth times when i closed a game.
Just take into consideration that most of these crashes are due to incompatibility between ICS and apps that don't officially support it yet. Not as much due to the device itself. So returning it and getting a phone running gingerbread won't solve the crashed when that phone eventually gets ICS....
I get it every few days too. Crash followed by what looks like the phone trying to reboot, but screen just goes dead and I need to pull battery to restart it.
i have had this too a few times. the screen just turns off, and won't turn back on. have to pull the battery before i can turn it back on.
this last time, i was just in the sms app, reading a message. i noticed the text was rendering strangely, with sort of colours around the edges of the letters, as if it was a low-res screen. then just as i tapped the message, to try to see if the rendering would change if i highlighted it, the screen turned off, and the phone seems to be dead, requiring a battery pull before i am able to turn it back on.
i haven't pulled the battery yet, and the phone is still sitting apparently dead. however i also notice that despite the screen being off, and it sitting here for a while doing what seems like nothing, the top half of the phone is actually pretty hot (front and back). not due to the screen having been on either, because the bottom half is cold.
Try turning off the eq in the music player. Worked for me it seems.

Based on the replies received so far, I think it is fair to say that these crashes are most likely related to software issues (as opposed to hardware). I guess patience is due while our bleeding edge technology stabilizes..
me too
Yes, i have also had a crash twice in the one week that I have had sgn which required a battery pull to turn the phone back on. I think the first time, I was in the settings and it looked like a few pixels were going crazy then screen went black and I had to pull battery. Then about 5 days later, I was not using the phone but when I went back to it, the screen was black and I couldn't turn it on untill battery pull. Watching this thread with interest.
Had it a few minutes ago with Facebook. Had just opened it when it turned black. No button responded. Eventually managed to get back in menu. Considered removing the app.

Didn't have a black screen so far, but had it freeze 3 times in the week that I own it (2x Google Maps, 1x in Gallery when pressing home button). Screen stays just as it is, no corruption, no dimming, no response to anything.
I had similar problems guys and horrible battery life. It is 100% an app you downloaded.
Do a complete wipe or figure out which app it is one by one. I did the second method and I only lose 1% of battery life an hour on standby.

I'm looking for any ideas for the problem I'm having on my G2. I'm afraid it's a hardware problem and not much I can do about it.
I started having problems after upgrading from CM 7.1 to 7.2, but I don't think it was related to the upgrade. I started having battery draining problems, the phone took forever to get fully charged, and car mode would automatically start sometimes when plugging up or unplugging the charger. I cleaned the usb port with alcohol (with battery removed), let dry, and restarted. Now I don't have the car mode problem and the battery problem is somewhat better.
My problem now is that the phone will just die when I'm using it. Usually when I'm using the browser. I'll be scrolling on a page and the phone will just turn itself off. Like the battery died. I can turn the phone back on and it will start up, get all the way started back up, but while it is still loading the home screen widgets, it will go off again. I can repeat this several times. The only way to recover is to plug in the charger. I don't have to hit the power button again, just plugging in the charger will start up recovery mode automatically, I'll choose reboot and the phone will start normally then and stay on.
The phone never dies when I'm not using it. I'll carry it all day, making phone calls on and off, and it'll stay on with no problem. Mostly, I only have the problem when using the browser. Also had the problem while using my newsreader. Once during playing a game. But if I start up browsing the internet, it doesn't take long before it will turn itself off. A matter of a couple of minutes. I don't have the problem with reading emails with K9. Don't have a problem in downloading from the internet such as podcasts. Don't have a problem in sending text messages. Don't recall it shutting down while using the Facebook app. After putting up with this for a week, some troubleshooting and observations.
I never have this problem if the charger is plugged in. Only when it is running fully from the battery.
I've tried swapping to a different battery.
Turned down the overclocking with no difference.
I've changed to other recoveries, CM 7.2, CM 7.1, a CM 7.1 that I was running in May. No difference.
I've swapped memory cards.
I've reset battery stats.
No difference if running on wifi or just data.
Clearing caches made no difference.
So, I start thinking it must be a hardware problem, but then why does it only crop up when internet browsing. Must be power related since plugging in the charger makes it go away, but why does it not have a problem with using the phone in other ways?
Any suggestions on what I could try?
You could try to see if there is too much voltage drop when you start something power-hungry. Use a battery voltage logger and post the results. Start logging, let the phoneidle for a minute and then start browsing. Even if the phone shut off, the log should still be there after rebooting.
Thanks for the idea. I can't locate a logger that looks like it would work. It would have to capture a quick drop in voltage that is momentary. This problem happens even on a full battery and when the phone come back on (either momentarily or after a recovery reboot) the battery level is unchanged.
You might try as well an other way: first idle, then gradually step up to a more power hungry app to see when the problem actually happens. I have no other ideas...
Make sure that you dont have any contact with the battery and the door.
Normally batteries are covered with an aluminum wrap, and can cause short-cuts with the phone itself.
I searched it for a while with the galilio batteries.
You can try to put some saranhwrap around the battery.
I have the same problem with two different batteries. But I'm ready to try that too.
Battery graph
So here's a graph of my battery status. Long time to charge to 100%. Discharges pretty rapidly. Each downturn ends in the phone turning itself off. Notice that at 7:30 today, it turned itself off, I did a recovery reboot, then noticed it wasn't charging very well (green line turns to blue but doesn't increase), then I did a manual reboot and when the phone restarted, it showed the battery was at 100% charge (from about 60% before the reboot).
What do you think - hardware or software?

Well, I just took the cover off for awhile and tried it. Played crosswords (Shortz) for awhile with no problems. Started my newsreader (Newsrob) and it shut itself off in about 15 seconds. So, no short to the battery cover.
Same thing is happening to me. I use poweramp or the browser and the G2 just shuts off. Then I restart it and it tells me that the battery is low. Once I shut it down and reboot in recovery and wipe the battery cache it's back to it's normal battery level. I disabled data and set my phone for 2G networks only and it didn't shut off after. I'm assuming this is a wireless issue? I'm running mimicry 1.3.0 on my G2.
Had the same problem. Swapped out batteries and problem gone.

Did you swap the battery and immediately have no further problems? I tried swapping my battery already and still have the same problem.
This has been bugging me for a while and im not sure if its a universal issue or just me,
When they updated the HOX from 4.0.3 to 4.1.1 they introduced the power saving mode, which one of the features involves shutting down the 3G radio when the screen is off and turning it on periodically to for email/whatsapp/facebook/whatever...
So all push notification only work periodically every X minutes instead of being almost instantaneous.
No problem, we turn off power saving mode and its suppose to be disable leaving the 3G radio operational at all times, no ?
Well... no. apparently its a problem im encountering in all sense roms, they all have the same issue, the 3G power saving is still on even if i turn off power saving mode,
Anyone else experiences this ?
If I remember correctly, basically our phones have 3 states: awake/active (your using it), a sort of light sleep, and after some time of not using sleep. I believe that when it goes to sleep the phone will not reconnect to data to update unless the app tells the phones to come out of the 3rd stage, sleep. So really it all depends on how often you have your apps set to update. If you believe you're apps are set correctly and your phone should be waking to update, you can get an app from the play store like gsam and you will want to look for anything that says wake locks. An app that wake locks is an app that is bringing your phone out of sleep to update and so forth. I would start with those things to see if your apps are behaving as they should.
I'm experiencing a weird problem with my M8. The unit would turn itself off all of a sudden. This happens without a low battery warning and no other error messages or warning displayed on screen. No beeps or audio cues, either. I would be looking at it and using it as per normal when it would just power down and turn off all by itself. This has happened twice in the last two weeks. In both instances, they have these in common:
a) Battery was low but not critically so. IIRC, the first time it happened the battery was at 25% and the latest incidence the battery was at 18%. The low battery warning usually given at 15% power wasn't displayed.
b) In both cases, I've just only turned the display on & started using the M8 for less than 15 seconds before it turns off.
c) In both instances, the mobile data & GPS was on. Wifi was off. Phone wasn't charging and the camera/flash was also off.
What I do after this happens is I would go home & charge the phone using the original M8 charger. The charging battery icon would be displayed and the charging level tallies with the last charge level that I see before the phone turns off. I let the phone charge for about 10 minutes or so before tinkering with it.
What's frustrating is that after these sudden shutdowns, some of my settings were reset & the phone will be wonky. I had to re-do the settings in both the settings app & also Google settings according to my preferences. Some default apps were cleared as well, so the phone would ask which app I'd like to use for my Home screen (either Sense Home or Nova Launcher, which I use exclusively). Some developer options were reset too, e.g animation scale etc. Other basic settings as well, such as auto updating apps in Google Play Store.
Also, first time it happened, I was locked out of my phone. The lock screen is displayed but all the PIN combinations I've tried seems to be wrong. The lock screen would go off after I try inputting the PIN. Restart by pressing vol button with power button didn't work at all. I'd touch the screen, the lock screen will be displayed, I'd try inputting PIN but I guess it's wrong because the screen just goes off. In the end, I had to reset the PIN number using Android Device Manager on Chrome running on my desktop PC. Only then was I able to access my phone. My wallpaper was reset, although my app icons on the desktop was the same as before. Apps were all there.
The 2nd time this happened was yesterday. I wasn't locked out of my phone but all my text messages (SMS) were lost. No other loss of data, as far as I can tell. But some of the settings, default app preferences & also app permissions were reset. Had to redo them all over again. Getting a bit tiring, this.
I don't understand what's happening. My M8 is on 6.0, stock ROM & unrooted. Never rooted. I've done the battery calibration steps once but that was before the Marshmallow update. When my M8 was running Lollipop, there were times when it would turn itself off as well but it was triggered by using the camera flash at low battery levels. However, settings, app preferences & permissions were not reset at all then.
Has this happened to anyone? What could be wrong? Would appreciate any & all feedback Thanks in advance.
This happens to me too. My battery is dodgy and it turns itself off when the battery is displaying anywhere up to 30%!! What I have found is that if you attempt to turn the phone on and it turns back off during the boot process then this is what screws up the settings. As long as it is charging and completes the boot without turning off then the settings are fine.
This is a MM problem. Wasn't present with LP as you and others have reported.
The only possible fixes on your end is to do a factory reset and then run the phone down until it shuts off and then charge to 100% with the phone still off. You can also try holding power+vol up+vol down for 2 minutes. This should wipe battery calibration stats. These suggestions may or may not resolve the problem but are worth trying.

Its happening to me!
I thought this was MM issue but i have flashed cm 14.1 and still the same problem is happening. My phone turns of somewhere between 15%-30% everytime. I have tried re-calibrating the battery but it didn't help. Now i am thinking to sell the device due to this issue.
My girlfriend had the same problem with her HTC one M8.
I've replaced the memorycard with a new one last week and it didn't happen since. Hopefully this will solve the problem
Hi together.
I want to give an information about my experience with sudden shut off. I had this issue with my M8 since about six months now. Tried the stuff with recalibrating the accu without success.
Last thing I did was changing the accu. And now everything is all right. The power is remaining much longer over the daily use and I can bring it down below 15% without sudden death.
