Device functions much cooler in airplane mode... - Nexus 4 General

Titles says it all, really. I was playing GTA 3 for quite a while in airplane mode (wifi on) and the phone barely warmed up at all... previously the back near the camera would start getting hot to the touch after the same amount of time. Performance clearly improved also, due to less aggressive throttling I can only assume. When I have time I plan on investigating further; in the mean time I figured why not make a thread. Anyone else experience this? Your thoughts?
Edit: I am in an area with moderate H connectivity, and was playing indoors. My N4 usually sticks to it unless I death grip it. Now my N1 would have been a different story, as that device constantly switched back and forth from H to E practically anywhere in my apartment.

I played NFS3 airplane mode, only wifi on, phone got hot. Not boiling hot but hotter than when i record 1080p video for a long time and there are apps/processes that didn't get killed run in background.

What's your phone temperature right now?

I've been having some abnormal temperature in my N1 today, and it's got me a little bit worried. It's at 35ºC right now, while not doing anything. It's been a hot day alright, but I doubt that can have such a strong impact can it?
What is your phone's temperature when idle? What can be considered "outside normal"?
31c in the daytime, 28-30c at night.
i believe its safe, anything under 45c
It's weird though, it had never done that. I even turned it off for some time, but still. The antenna cover is definitely hot.
26.3°C right now.
26.6 'C here now..

Right now (indoors with cool temp) its at 80.6*F
Outdoors mine will get to about 90 - 95*F usually since I am using 3g, sometimes GPS, and the brightness is maxed out.
I dont let it get passed 99*F though since that would harm the battery. Good thing is though is it's never gotten to that point
32C right now. I've gone over 50C when using it as a GPS in sunny weather. Battery seems to be fine. Replacement battery at $25 (cheaper if you shop around), so I figured an average battery lifespan of 1 year isn't a big deal.
Damn, you guys have cold phones. Ive never seen my phone below 32c. Even if I check in the morning right when I wake up.
25C.
Lowest I've seen often is 21-22 C, but that is only overnight and I put my phone on airplane mode.
For those of you with hot phones, do you live in hot climates? I've noticed my phone stays warm when I'm out in the sun.
Also, make sure you don't have widgets/etc syncing all the time. I set them to 1 hour at most, and often 4 hours.
29.6.......
Running FroYo and OC kernel atm, so usually range from 26C-38C, anything higher than 40C freaks me out so I set up failsafe on SetCPU. Lowest I've got was 18C/19C with Enom's 1.8.1|IR's kernel.

Got widgets, news, contacts & email synching all the time. So my phone is constantly over 30c. Goes under 30c at night time (less activity perhaps). Regardless, the battery should be sufficiently warmed if you want to keep a charge. Just don't hit the 50C mark too many times though, which is pretty much unavoidable when you use GPS a lot.
But I've noticed that after upgrading to Froyo 2.2 the battery seems to run cooler and drains much less compared to 2.1. That and a boost in performance is short of ingenious on Google's engineer's part.
However, I reverted back to CM 5.0.7.1 cuz it's just not as polished yet. Waiting for CM6 instead.
I think there definitely is something wrong with the phone... I woke up and it was cool when I took it from the stand, then I browsed a couple web pages and I canalready feel it getting warm. It got burning hot when I charged it yesterday, too.
In case it is a hardware problem, what could be the cause?
I've just removed the battery and, surprisingly, it's cool. It's the antenna cover, the plastic part at the bottom where it says HTC, that seems to be getting hot. Does that even make sense?

Galaxy S getting hot at times? Or is it just mine?

I've had my Galaxy S for a week and of all the reported problems the worst for me is the phone gets hot sometimes in use and while charging. I checked in the application system I downloaded from the android market and it showed temperatures up to 53 degrees celsius. This makes the phone impossible to hold to the ear for a phone call and even internet browsing difficult as it gets too hot to touch.
As a side note unless the carphonewarehouse offer you a 7/14 day return policy don't buy from them. I'm having problems now because of it.
I can't post links to the pictures I took showing this as my account is still new, but it's on picasa web album under galaxy s temperatures and I can send you the link in a message if you want.
Has anyone else experience this problem?
I did notice that the phone can get quite warm at times. But for me even after 1hour in the sun outside the phone wasn't uncomfortable to touch. Much less to hot to hold to the ear.
My phone is charging right now and temp is 44 degrees centigrade. But considering the room-temp is almost 35, its not that bad. I'd rather have my phone becoming a bit warm than it taking forever to charge.
Ive only noticed this when gaming and charging from AC, its not that big a problem for me really, all smartphones suffer from this to some degree. My old Touch HD would get really hot if just wifi was active which is more annoying than this.
Well I have the desire as well and had many smart phones in the past that got warm but never as hot as the galaxy s, nor as frequently when used. It doesn't stay hot, but when it gets hot I can't put it to my ear to phone people. It happens mid call after I've use the phone for awhile.
Well that doesnt sound right, mine doesnt get hot like that, so perhaps yours is faulty?

Same here (USB also)
but other than that the phone remains colder than my HTC Magic.
It does get hot sometimes during calling but not that much.
I just got a new one (old one replaced) and I'm disappointed I'm suffering from this problem also. Mine also reaches up to 53 degrees.
have same problem but....
I downloaded a app "Advanced Task Killer" and killed all the apps that were working in background and i use from time to time, like YMessenger, Mail....
now the phone even if its charging the temp is between 35C and 40C. and maybe the battery will not discharge that fast
well it gets warm here 2 . but i had the same with my iphone 3g .i think its the working of the processor that makes it hot .its the same as with a pc when you run it to its high performance it gets hot 2

that sounds like normal
my old HTC Athena, gets really hot after long sessions of WiFi, 3G, or GPS, and in the SGS i get similar temperature when using the same stuff.
no heat from Bluetooth, or at least it's not noticeable
but ALL cell phones gets hot after long voice conversations.
Some times
Allways when im playing games my SGS gets pretty hot but not in AC .
From the troubleshootig section of the manual -
Your device is hot to the touch
When you use applications that require more power or use
applications on your device for an extended period of time,
your device may feel hot to the touch. This is normal and
should not affect your device's lifespan or performance.
It gets quite hot sometimes. Battery might rise from 33C in idle to around 45C on load.
I think it is the GPS chipset doing really weird calculations. That happened to me in the hardest math classes in college. Whenever I was totally lost and clueless about something during a calculus test I'd always get nervous and hot and sweaty.
Never killed me tho. I think the SGS will be fine even while hot.
I had the VIbrant for a week now.. i can't really say its gotten hot... maybe once.. but its not something severe, because i can't really remember how hot it was...
but from my research... iPhone4 is doing it, people complained they couldn't hold it close to their face while talking..... All the 1ghz SnapDragon's been doing it...there has been reports of the device too hot to even charge....even the underlcocked Acer Liquid E....
I've actually overused it the first few days...i can't really recall this happening to my phone...
Charging with screen on made my SGS rather hot. So now I try to leave the screen off when charging. Come winter that might change, not always a disadvantage to have something hot in a cold car
Seems to get hot in a location around the SIM card area on the phone when charging from USB or AC.
Not worried about it though.
Today try out the Fancy Widget, but later uninstalled it, I already disabled auto refresh everything, but my SGS get overheated and battery down by 50% just in 5 hours.. ......Anyone know why?
charging time
How long does your phone takes to charge ?
Mine takes about 3-4 hour hours on pc usb and about 3 hours on power adapter come with the phone.
My HTC tytn2 with extended battery 2800 only takes 2.5 hours to charge over the pc usb charge.
Mine's getting a little bit hot after trying some 3d games (asphalt i.e, i don't play too much) or clips (few minutes). it seems to have a particular "hot spot" at the portion of the sim card/sd card, the rest of the phone feels quite cool, and i can hold it without any hassle.
Charging the phone at the moment. 42 celcius.
Are you using setcpu? 10 mins ago I was using setcpu and noticed my phone gotten hot suddenly - I didnt do any sort of ocing. Checked the temperature and was shocked to see 53c Uninstalled it and the temperatre returns to a more acceptable level

[Q] Maximizing battery life as much as possible?

Before anyone accuse me of it, I did, in fact, look through the other battery threads on this forum (and other forums, for that matter), and I've already applied numerous tricks. I managed to get my phone to last roughly 9 hours from my typical usage, which now makes it comparable to other phones I've used in the past.
However, in about a day or two, I'm going to be getting a bluetooth headset...which basically means that I'm going to need to keep the Captivate's bluetooth on 24/7 (or, at least, most of the day). I really don't know how much battery this is going to cost me on the Captivate, so I'm trying my best to make things better now to make things smooth in the future. However, I appear to be at the end of my rope.
I have pretty much gimped the Captivate as much as one could reasonably take (more, I'd dare argue). I cut all of my volume down to half of what it was and I removed most of the quick icons. I also set a completely black wallpaper, I turned off all animation, and I turned the brightness down to its lowest setting.
I honestly don't know how to make it any worse. The SAMOLED screen is basically a meaningless PR term to me now and I'm actually missing phone calls from sheer lacking of hearing my phone ring...despite it being right in my pocket.
Going even further, I also attempted to switch to ADW.Launcher based upon recommendations by others that it increases battery life (I found that it had little to no effect). I also attempted to severely underclock my CPU (down to 200Mhz) based, again, upon other claims that it increases their battery life all the way to as high as 30+ hours on a single full charge.
Somehow, underclocking my CPU actually made the battery die out faster.
Furthermore, I attempted to use programs (SMODA, 2G/3G) which claim they allow me to switch to EDGE because, for some God-forsaken reason, Android doesn’t seem to have any toggle for doing it. Unfortunately, none of them seem to work; rather than switching to 2G, they all just completely disabled data, which, unfortunately, is completely unacceptable to me. So at this point, I only seem to have a few more extreme (from my perspective) options. Once I actually get the bluetooth, I plan to turn off most of the auto-updating apps (email, weather, twitter, etc), and just update them myself periodically. Furthermore, I plan to turn off the GPS location feature once I get my GPS unit.
Beyond the above, though, as I said, I'm at the end of my rope. Once I employ the other tricks, I figure I might be able to stretch battery life to 9.5-10 hours, but I would like to go even further. If anyone could offer me some help, I would highly appreciate it.
if your gonna have a bluetooth headset on disable your ringtone completly that would be meaning less. if your near wi-fi a lot have it connect only though that.
also you can clock the cpu down to 100Mhz along with the GPU.
AND to force 2G/edge read my howto in general
oh the ext2 lagfix can also save you some battery life

I'm already doing the first sans disabling ringtone. I'm not so sure doing such a thing would be acceptable to me.
As for the underlocking suggestion, as I said, I underclocked the CPU all the way down to 200Mhz and the battery actually drained even faster. I doubt underclocking even further is going to help. Furthermore, I actually did try 100Mhz originally, but the performance was so horrendous that it was unbearable.
As for the lag fix, I already have it. Lastly, I knew about that 4636 technique to switch to 2G already, but, unfortunately, it doesn't appear to work for me. The setting doesn't save and 3G still remains.
EDIT: I actually found a way to make the above work. Simply dial *#*#197328640#*#*, then go Debug Screen > Phone Control > UE State Control > Change RAT to GSM. This will actually force your phone to use GSM only. This seems like the answer to all of my battery problems....except it doesn't work. Once you make the change, the INFO menu reports that it has been changed to 'GSM Only', but data appears to have been disabled. Restarting your phone makes data works again, but the INFO menu reported that data has been reset back to 'GSM/CDMA auto'. Yay.
If you haven't already, turn off GPS when you aren't using it. Use the Power Control widget to help. Make sure all of the things in the power control widget are off unless you are using it. And use advanced task killer if you haven't already.
i say screw underclocking let run at whatever i dont think it makes a difference.
forget advanced task killer, i like auto killer.
leave gps off unless needed, and backround data
switch to 2g when you can.
no live walls of course use dark or black, no updating widgets
i dumped stuff like juice defender, cause with backround data off i dont think it does anything.
flight mode it at night (when sleeping) if not charging
ive been running jh3 (now jh7) with sre. get to work (i run 2g at work)at 9am listen to pandora all day through bluetooth (which is on for 6-8hrs) and wifi (6-8hrs) good amount off browsing bout 30 min of voice calls, some texts email checking, more browsing, some games. on average lately after being unplugged for 13-17 hrs at the end of the day with 20-30% life left,using bout 3hrs of display, 30 min voice calls, bluetooth doesnt use crap bout 3%, media server usually 15%, cell satndby i wanna say 10%, im pretty happy i guess, even though im always lookin for better results, tryin the new sre with undervolting, heard some good things.
still when that seidio 3200 mah battery comes out im gettin it, dont care how fat it makes the phone, things to dang thin as it is, and without some sort of cover its like a wet bar of soap!!
What is your typical daily usage? I have fairly light usage (few games here and there a little music and a good amount of web surfing, app browsing and texting with a few phone calls using speaker phone) and I'm at 28 hours of use with 55% battery.
I have just the typical power saving tricks(gps off, bluetooth off, screen at minimum or 30% and my data doesn't sync automatically), no under clocking or anything. I should point out I'm running a euro galaxy rom and am not ever on a wifi connection.

Wow you are lucky. Yesterday I got 2 phone calls for a total of 3 minutes. I sent 7 text messages. I surfed the web maybe for 15 minutes. No games. Nothing else major. GPS off. Bluetooth off. Wifi on. Screen at 22%. Only background data I have is email which checks once every hour and a weather widget that refreshes every 6 hours. I got barely 12 hours in before my battery died.

Typical usage for me runs along this line: A lot of web browsing, perhaps 30-45 minutes of music, and plenty of IM. I also use Aldiko to read now and then. Calls do factor into this, but typically only two or three 10-15 minute phone calls.
Truthfully, I simply don't see how it is possible for you to use the phone for 28 hours straight and still have 55% battery. I could lose 30% battery just by leaving my Captivate on stand-by for 30 hours.
I certainly understand the interest in having the best battery life possible.
Are you in a work environment where you cannot plug it to a computer for part of the day?
Fortunately, I am. And I always have it plugged in in the car.
I don't want to have a powerful phone with all the features turned off in order to keep it going.
I dont see how you can get 28hrs @ 55% either, with the kind of usage he was claiming, i wouldnt exactly call that light usage

Well, I do have a work environment where I can keep my Captivate plugged in, but only half of the time. Other times, I need to move. Aside from that, it kind of annoys me to use a phone attached to a wall socket. I prefer to keep my smartphones plugged in only long enough for them to fully charge (or at least charge to 80+%), then unplug them for usage. This is kind of tough for the Captivate considering it takes 3-4 hours to fully charge.
I also fully agree with you on the last point, which is what makes all of this so frustrating.
*Sigh* It's really too bad the Captivate is my first Android phone; it's been kind of a negative experience for me so far. Ironically enough, the one issue that hasn't been a problem for me is the one issue most seem to be having -- GPS performance.

I am in class for most of the day so the phone is idle most of the time but i only play about 10 minutes of music with about an hour or 2 combined web surfing and games but my phone is still chugging at 39 percent battery life at 38 hours of usage. I guess that qualifies as light usage then.
edit: jm6 with unhelpful kernel and sre
also, you have let the battery die out completely and recharge completely with the phone powered off correct?

I'm honestly shocked at your usage. Am I reading right that in the 38 hours since you last charged it, you only used it for 10 minutes of music and a combined 1-2 hours of web surfing/games? I wouldn't call that light usage. I would call that hardly any usage.
Under such conditions, I can see why your battery life lasts so long.
I don't see why you can't get a days worth of usage out of your phone. Cell phone calls use the most battery - that is why the phone is rated at about 5 hours of talk time. This would be in the best signal area. If you are in a lower signal environment (especially in a heavy building all day) you will see faster battery drain.
I am not sure why you are bothering with BT if you are only talking on 2 or 3 calls - but if you take 3 15 minute calls that is at least 15% of your battery - the only way to change this is force the phone to Edge.
I would not lower ringtone volume - that is not a big battery saver in the grand scheme of things and you are missing calls - not a good trade off. If you are doing a lot of web surfing, go WiFi instead and you will see big battery imrovements. 3G voice and data suck battery - it doesn't matter if you have android or iPhone.
If you put your phone in Airplane mode you can go for 5 days between charges with minimum use.
The radio does kill the battery, I don't think the battery usage screen really depicts this. Since I've gotten my captivate my old BB Bold (at the time would only last 3 hours due to its degraded battery) lasts days on end with its radio disabled while sitting in my desk. I'd love to see native 3G toggle or at least a captivate catered app, I'd even pay for the latter

Well, that rating is probably the battery life if your decide to talk on your phone for five hours straight. I really, really doubt it takes into consideration the in-between times (games, apps, and, of course, web surfing). Phone calls undoubtedly takes the most amount of battery, but Internet usage is probably second place and, as said, I use that fairly often.
Lastly, I'm not planning to use my bluetooth exclusively for phone calls. I'm going to use it for calls, listen to music on the Captivate, chat on my PC, and so on. It's multi-usage.
Next, you're missing a lot of the things I said. As I said, I already tried numerous methods to force the phone into 2G; not one of them works (they either don't work at all or actually completely disable my data). I'm already using wifi as opposed to 3G as much as possible.
Lastly, I'm sorry, but using airplane mode to save battery is not acceptable. If I'm even willing to consider this, then I might as well just turn off the Captivate to save battery.
I just read something about an external sd card being another battery drain.
Took mine out and we will see. I was already getting through the day with about 20%left.

I didn't meant to suggest that airplane mode was an alternative, just to point out that the cell radio for Voice and Data is your biggest drain.
If you are going to use the phone for almost an hour of talk time, heavy web surfing and BT connections for tethering then your battery life will be limited. If you are using BT to chat on your pc - then maybe tethering with USB would be better - you could charge at the same time.
Your other option is to get a spare battery.
And I did read what you had to say, I just didn't realize how much you were expecting your phone to do. The only numbers your provider were around talk time.
I use my phone a lot and I charge it every 24 hours - I am more then satisfied - but I know that if a spend an hour or more talking on it and bunch of web surfing that I will have to think about charging it as my usage increases.
There is a way to force the phone into 2G. It isn't very user friendly. I have tested this and it works great.
Enter the Phone app.
Dial *#*#197328640#*#*

Is it normal for smart phones to get hot while on 3G?

I've had my Nexus 1 for almost a year now, but it was only after about 6 months I noticed my phone was rapidly heating up after using the 3G signal. It will raise about 5-10 degrees within minutes and you can really feel it getting warm. As soon as I stop using 3G the temperature dissipates rapidly. It never gets hot on wifi though.
So I ask, is this normal for smart phones these days? Or is something wrong?
Yeah smart phones get warm/hot when getting used. They're mini-computers now.
My N95 used to do it as well.
The best thing for temperature rises is using navigation; you have 3G, GPS, screen, sound constantly in use, and often plugged in.
I don't think the OP was talking about smartphone use in general. From what i can gather he's noticing a temperature rise from 3G use alone and that doesn't sound right.
Running a resource intensive app will of course heat the phone up through the cpu/soc usage, but from 3G itself...?
Perhaps a Task Manager app might give you a clue as to what's going on. Maybe switching to 3G is ramping up your cpu or perhaps some app is doing the same in the background.
i notice my phone gets very hot anytime i have a phone call on 3g, or a long data session on 3g. but yes its pretty normal to get warm.
but it is not normal if your phone is sitting idle on 3g and it gets hot. that's not normal.
I have checked recent apps, no apps are taking up much battery at all. Do you think its damaging? It does make me feel uneasy, but if it won't damage anything or do any harm I guess I can tolerate it until I decide to upgrade 12 months later maybe.
I'm in Australia and bought my phone from The States so I'm not really in a position to return under warrenty
its pretty normal
Since your Nexus one is almost a year old I would replace the battery and get a new original one. I have notice after 1.5 years they tent to overheat easy and get fat. My nexus one gets super hot when I use it for an hour while charging.

HTC One M7 Battery Drain and Overheating

I just replaced my aging iphone 4 with an HTC One M7.
So far, I'm loving having an Android phone, and I'm really glad I switched, but I seem to be having a problem with the phone.
It is getting pretty hot and the battery is draining alarmingly fast.
The phone was reset to factory settings when I received it yesterday, and it is the AT&T software version. It is on Android 4.4.2
Although this is my first Android phone, it is not my first Android device (Xperia Play used as a portable emulator, Nvidia Shield, Asus Memo Pad HD7) so I knew the obvious things to try.
The phone feels slightly warm at all times, even when just sitting in my pocket. When I have a CPU-intensive app (youtube for instance) running, the phone gets pretty hot.
I understand that the aluminum chassis transmits heat very efficiently, and that this phone should feel warmer than a plastic phone, so I installed a CPU temperature app.
I'm getting in the high 40's to low 50's (celsius) with no CPU-intensive apps running.
Looking in my running apps, I don't see anything that looks like it is making heavy demands on the CPU.
While at work today, I put it in airplane mode (but kept wifi on) because I don't get a very good signal at work anyway, and I thought this might be causing the battery to drain quickly.
I forgot about this, and so the phone has been in airplane mode since 1pm today (it is now 8:45).
While browsing the internet just now looking for a solution to the problem, I watched as the last 18% of the battery drained down to 1% in around 15 minutes.
This is in airplane mode, with battery saving mode activated, Blinkfeed deactivated, and the screen on minimum brightness.
Does this sound like abnormal behavior?
I need to know fast, because if there is something wrong with the phone, I need to return it without delay.

I just replaced my aging iphone 4 with an HTC One M7.
So far, I'm loving having an Android phone, and I'm really glad I switched, but I seem to be having a problem with the phone.
It is getting pretty hot and the battery is draining alarmingly fast.

Is the phone brand new? It runs more the first time you turn it on, I think due to some profiling. If it's still like that the day after turning it on for the first time I'd probably be concerned. It could be due to something you've installed--what have you installed (if you don't mind sharing)?
I've definitely experienced what you're talking about on CyanogenMod, but never that I can recall on the stock ROM. When it happened on CyanogenMod, rebooting generally seemed to fix it.
