i9100 + GPS + overheat - Galaxy S II Q&A, Help & Troubleshooting

Hey guys, I was recently testing different android GPS apps (copilot and sygic so far ) and I noticed my phone warm up noticably upon running those apps with GPS on. I tried flashing to a KH3 modem firmware (as suggested by some members of these forums) but that did not change the behavior. I tried two different programs and it overheats in both. Is this normal behavior? !

It is kinda normal.
Sometimes it gets a little better when using another modem but not really much better.
Good luck
Dip

It's actually two problems.... the heat and the rate at which it drains when its hot... I went down from 91% to 55% in a 1.5 hour trip with nothing but GPS on..

1) Modem has nothing to do with GPS.
2) Yes, normal for phone to get hot when you use CPU/GPU intensive apps, tho this might be a rom/kernel issue. I find mine doesn't get above high 20's C when using GPS for a while. Do you find the phone heats up a lot when you use other CPU/GPU intensive apps ?
3) And yes, GPS does drain a helluva lot of juice. Best thing you can do is get a car charger & plug the phone in while you're using GPS to offset the drain. Is losing 36% over 1.5 hrs of GPS use normal ? I don't know that there is a 'normal' so far as drain is concerned (it's variable). I guess other people might be able to give you a better idea of that than me, or you could try other roms & see if you get similar results with those.

Anyone else had a similar experience?

For the heating problem, you should try speedmod kernel, or phenomenal.
And if you have any doubts about the battery drain, take a look at, let say, a Garmin GPS device. Unplugged they don't last more than 3 hours. And they have an awful resolution, a tiny processor, don't use network, and a dedicated OS.

battery draining while using GPS.

I just went on a trip and about 2 or so hours into the trip my cell phone went dead even though it was plugged in. I was using my GPS. I recharged my phone and tried again and I could see the battery was draining even though it was plugged in.
Is there a fix for this problem? I'm was using Sprint ROM, but switched to Might Mikes, but still have the same problem.
what ends up happening with the pda devices is that it looks to the battery for energy only. even if it's plugged in if you drain the battery faster than it can charge then it will go dead. i don't know if there is even a different rom that can cercumvent that, but that would be the only way to fix it.
...or if you could find a gps program that uses less energy. that should work too.
I tried again using the GPS, but this time I had a DC to AC converter and plugged in my phone. Although I didn't run the GPS that long, maybe a half hour or so, the phone battery didn't loose any noticeable charge. It was fully charged when I stopped the GPS.
I'm also looking to replace my battery with a higher capacity battery. Can anyone make a recommendation? I don't want a larger battery as far as size, but one that has more capacity. Let me know if there is a battery on the market that will meet my requirements.
Touch Pro has a safety feature to stop charging when the temperature sensor goes past a certain point. It is much more likely to reach that point when you are running GPS and in car with the sun beating down.
Workaround for that is to turn on the AC.
I had the same issue this May when driving through GA while on vacation.
The phone does stop the charging process when it feels it is too hot but will continue to operate thus discharging the battery quickly but never letting you get a charge in.
My solution was to buy a mount for the phone that clipped onto the AC vent and let cool air run on it the entire time and that solved the problem.
Hope that helps.
Yes, anytime I run the GPS the phone does get warm. However, I do have a vent mount holder for the phone with AC blowing right on the back of it. That doesn't resolve my problem.
I'm interested in a very high capacity battery if anyone can personally recommend one.
Have only had my sprint pro for 2 weeks and concur the battery life is bad. I find heating problems during lots of tasks and sometimes doing seemingly nothing(in sleep mode). I found that my gps was draining the battery even when not in use. I installed a cab to toggle it and that has helped alot. My data is set to go off automatically after a short time also. I'm trying every tweak I can think of and googling for more.
The oem batt was 1340mAh, My old gsm pro had an extended 1500mAh which I tried , with little improvement. I'm currently running a 2000mAh extended with the enlarged door and this helps but lots of juice is still draining away. On a positive note, the warmness seems to be mostly gone. My goal is to be able to go a full day with moderate usage. Today may be the day. I think I saw a 3000mAh as well, maybe at seidio. I was going to return the pro and get another one, but it sounds like they are all the same issue. An awesome phone, a real shame this is a problem. I think data off and gps off will help me alot. My $.02

[Q] Battery Drain Problem

Hello all,
I purchased a Galaxy S2 at the end of July, I live in the US, so it was from Amazon. The phone has been phenomenal, an amazing piece of technology.
I rooted the phone and flashed Lite'ning Rom 6.1 XXKH3. Still worked great, with no problems at all.
However, starting about a week ago, I am getting an extremely fast battery drain. Since then, I have spent hours looking at threads trying to figure out what was going on. I updated the rom to UltraToxic Rom v8.0 XWKK5, still no change.
I used Titanium Backup to freeze many widgets and app processes, still no change. I am currently using better battery stats to monitor wake locks, however after managing the wake locks, still no change.
I then bought a replacement battery thinking that the battery may have been bad, sadly, there was no change.
I have been trying to find a solution to this and had tried many other suggestions in other threads to no avail. As of now I have come to the conclusion that the device might have some type of malfunction that is causing this.
Am I going crazy or am I missing something obvious? Any help would be greatly appreciated.
Thanks
I have also re-calibrated the battery, still no positive changes.
Seeing the battery graph, you have your screen on a lot of time. Screen sucks battery a lot, so there might be one of the causes of battery draing.
Also you seem to have all day enabled 3G/WiFi, that also sucks some battery with it.
You can try JuiceDefender and see if it can help you extend a little your battery.
change kernel
Try flashing hardcore's "SpeedMod Kernel" and you will never complain about your battery life.....
After flashing this kernel my worse battery life was 1day and 12h with 3.5h screen on and wifi 85% ON.

Lol.... It's obvious he has some kind of battery problem, he is not using the phone much, and galaxy S 2 should have at least 5-6 hours screen on time and the phone lasted 3 hours.

Since I had all data on the phone backed up, I did a factory reset. I also flashed the UltraToxic Rom v8.0 XWKK5 as well as the suggested SpeedMod Kernel. When the battery was at 100%, I calibrated the battery. I tried to leave the phone idle as much as possible, I did use the internet for about 10 minutes to check e-mail, news, etc. So now the phone is essentially "empty" in terms of apps downloaded, I got rid of all widgets on all home screens.
There was still no positive change, I do really like the SpeedMod Kernel though, I do notice faster responsiveness from the phone.
I am beginning to think that the problem may be the hardware and not the software or battery.
I've got similar problems here. I am suspecting a hardware problem (I damn well hope it isn't coz i got mine from hong kong) because my phone never goes into deep sleep mode for more than 50% while the screen is off. I've tried at least half a dozen different kernels and roms and nothing helps, this is even in airplane mode i.e. with pretty much everything turned off. I've tested wakelocks and dont get anything more than a couple of seconds. I had my battery charged to full at 6:30am this morning, went to work and got home and it was dead after just under 12 hours with being idle 75% of the time. This is worrying as most people's battery lasts at least a whole day.
So I know it can't be the kernel, I know it cant be wakelocks, I know it cant be wifi or 3g data or anything of that nature so the only thing it comes down to now is hardware...
Funnily enough I've had exactly the same issue since about a week ago. Even when I take it off charge it's almost immediately down to around 80%. It's lasting around 4-5 hours, even when I'm not using the phone much, plus it gets really hot.
A couple of times Social Hub has appeared high up on the list of battery draining apps, although I don't use it. It doesn't always show up though. I switched to the CF-Root kernel and started using GO Launcher EX recently and wondered if that (or one of it's addon widgets) could be the cause.
It's really bugging me now!
SOLVED!
After days and days of trying to fix the issue of the phone not sleeping (and therefore draining excess battery whilst idling) I have finally fixed it!!!!!
First i noticed that along with the sleep problems, I was getting the problems with car mode popping up randomly, the phone going into mtp connection mode, and thinking its charging when it was unplugged. After looking into these issues (and i thought it was a longshot) I decided to do what people were saying and CLEAN THE MICRO USB PORT.
Now you're probably thinking I am a crazy man, but now im just crazy happy that I don't have to send my phone back to Hong Kong!
Instructions:
1. Get a clean, dry, soft-bristled toothbrush.
2. Take any case you have off the phone.
3. Gently insert the bristles into the port and "flick" it out softly.
4. Repeat this about 10-15 times
No matter what ROM, what kernel, what modem i tried flashing, my phone was always sitting on no more than 50% deep sleep mode when idle and had no wakelocks or "rogue apps".
I am now getting 90% - 98% DEEP SLEEP MODE!
I obviously can't guarantee that it will work for everyone, heck how it solved the issue is a mystery to me, one which probably an electronically-minded/computer systems person could answer. What I can say though is I searched high and low online for about a week. I tried different kernels, I tried different ROMs, I tried "re-calibrating" the battery, I used BBS to check for partial wakelocks. If you too have tried all this and have had no success please PLEASE try this and see if you have success!!
Thanks for reading!
....
Or if you didnt...
TL;DR: If you're having battery drain problems clean the micro USB port with a soft toothbrush.
The phone never sleeps when charging, the CPU idles at 200 MHz, whatever was in your USB port was probably making contact with the pins that tells the phone it is connected to a charger when it actually is not, so it was idling at 200 MHz and was not receiving power, that's the only explanation I could fathom
Do two things:
Install CPU spy and show us what the deep sleep percentages are,
and try disabling wifi. Also, what is the router?
I have a battery drain issue; but its kind of screwey as i will reboot my phone and lose about 20% of the phones charge. If i turn it off and leave it off for an hour the charge comes back. Its random as well; only happens once a week. I have had this problem on different roms. You might have a similar problem to me. Possible the hardware that detects battery state is knackered.

Overheating and bad battery?

Hey. Im running the latest cm9 bit im having issues with it now. My phone gets very hot very quickly, even whrn it has been dormant for hoirs and i run the xda app on mimimum brightness. The entire phome gets extremely hot whilst charging as well overnight, extrrmelty hot.
Now time for the battery drain problem. I have heard reports saying people get up to 0.5% loss and hour bit i am getting 10-20% loss an hour with no use.
Sent from my GT-I9100 using XDA
To me that simply suggests you have a background service thats running constantly maybe some location service or download.
Remember just cause its running hot doesn't mean its overheating.
Cheers. Any idea how i can find this rogue program?
Sent from my GT-I9100 using XDA
There aren't any shortcuts when it comes to squeezing maximum battery life out of the phone. There is no 'do X & W and end up with 0.5% drain'. Every phone is setup differently, every phone is used differently. Basically you need to nail down what's causing that drain, and if it's things like apps syncing, or notifications or whatever, you need to make a decision as to whether stopping those apps doing that is something you're prepared to live with to save some juice (that was just an example, btw; could be heaps of things causing battery drain).
For starters, get BetterBatteryStats from Google Play, then post logs/screenshots in the BBS thread (or here) & someone should be able to help you. One thing tho, do not install BBS, let it run for 10 minutes (or 30 minutes or even an hour) & then start posting stuff. Let it run for a couple hrs/overnight/a day, that way the info you get will be more meaningful.
Other than that, it's simply a case of reading (a lot; understatement). There is a wealth of info on here re: your issues. You just have to find it.
Ditto with the overheating thing. It's normal for the phone to get warm on charge (particularly if you use it while it's charging). I don't think there is a 'normal' temperature, that is, some people report their phone reaching mid-40's C & not having any probs when charging, whereas mine tends to max out at mid 30's if I've really run it down (mine tends to charge warmer when there's a lot less juice left in the battery).
I think it could be something elsebas it is happening on cm9 and sammy based roms.
Sent from my GT-I9100 using XDA
You should also check CPU Spy and/or Badass Battery Monitor to identify what/when and why the Battery is drained. BBS is really good, but Badass is a little bit simplier to understand. CPU Spy help you to find out on which MHz your phone is running, sometimes that helps a lot.
As stated before, its a unique problem, not everyone is having the same issues, sometimes a normally working app is running wild or a new update from a previouslly good working app has a bug that gives your phone the creeps. Sometimes in BBS you will see eventX_XXXX messages, these are funny, because I never found out which process is behind this and aLogcat didn't help further (That was when I was on MIUI with my problems.). ATM I have no problems, so I don't need such apps, but aLogcat is funny to watch what happens there in the background and helps to find out what these eventX_XXXX Wakelocks and partial wakelocks are.
If its getting annoying hot near camera with no to little use you need a wipe or modem change.
I tried a wipe but unfortunately no difference. Can you suggest a better modem for me to use? Sorry if I am being annoying but I don't have much experience of this yet.
Sent from my GT-I9100 using XDA
you have to find modems, I personally only flash stock roms so modems comes with it, or use mobile Odin to flash just the modem from same roms.
Check the general thread, there's one specific thread about heat and modem
Format
Format you phone + system + external sdcard from cwm before installing the rom and try again

Galaxy Player 5.0 - uneven battery drain?

Hi,
I've had the Galaxy player for a few months now, and I'm generally very happy with it. Although I get pretty decent battery life out of it, I'd say normally about five to ten days of idle time with roughly six hours of screen on time and about as much wi-fi on time, with maybe an additional three hours as a music player, one issue relating to battery drain appears to be constant. I'm currently back on stock, but this also happened on Eryigit -- I get very slow drain from about 100-80%, then it seems like the battery goes into freefall, going down from 80% down to 25% in a matter of an hour to an hour and a half of regular use, then slows down again until the battery dies. I tried calibrating the battery several times with no difference. I'm guessing I'm getting pretty good use of the battery overall, but this erratic drainage pattern makes me feel like I'm too often close to running out as the device spends around half the time I'm using it at 25% or less. I've read somewhere that the battery level measurement on the Galaxy Player 5.0 is highly inaccurate, and in fact is only a guess based on the voltage output of the battery. I still have to wonder though, is this a normal pattern for this device?
Thanks, Nir
Hey. I've noticed a similar pattern via battery monitor widget, tho nowhere even close to ws prononced as yrs. I generally monitor the mA rate and it goes from -2ma steadily until 80%, the rate then speeds up. W moderate usage, i get roughly 2 days out of the sgp before charging, when there's roughly 30% or less left.
I also remembr some folks mentioning that the battery wont report greater than 80%; i imagine that 80% acts a sort of border where he readings r concerned.
Try out that program i mentioned to monitor usage. Personally, im on entropys kernel and chips rom (occasionally switching to paranoid android), have undervolted it slightly, and added a few init.d scriptsl aiming for optimal battry life. Also, try out watdhdog lite to monitor any apps that might be wakelocking improperly and Gemini app manager to disable ann0ying apps from starting on boot.

Bah, I think I might have gotten a bum battery. Any idea how much screen on time/wi-fi on time you're getting with a full charge? I use BetterBatteryStats to measure, which also helped me diagnose GPS-related drainage issues (those kernel wakelocks went away when I stopped turning off the GPS, but I'm pretty sure it's a stock kernel issue). I'll try out battery monitor. Thanks!
Well, given that you can have it on idle for 6 days, it might not be thay persay
Actually, onnsecond thought Powertutor is prolly better suited for your issue. It can monitor power use per application
High display brightness; wifi that doesnt sleep even w screen off (it never sleeps by default); apps that enable things like gps, that makes requests and sends info w.o yr consent thru wifi- these, among 0ther things, drain battry life and are other things to consider

And cant say. I usually do 2-3 days before i recharge; i rarely go under 20% and dont game
Also, just caught this- gps is a huge power suck. Like huge. That may be yr problem.

It was same for me on stock rom and every other rom..70% of time from 100 to 10 it is staying on 75% and 25%..and when its on 25% it can last all day with moderate usage dont moving from 25.Its because device only measure voltage which is innacuare ,voltage dont drop linear like mah.
Sent from my GT-I9000 using XDA
well i had that prob with my old SGP but since i messed it up andgot it replaced it doesnt stop at 80% for like an hour it just charges straight through tht was before i had enthropys512 kernel flashed....now the battery is faster to charge
Well, I suppose another plug for Battery Monitor Widget-
It provides a handy estimate for discharges/recharges that's proved pretty accurate. After entering the actual battery capacity and a few cycles, the app estimates charge and discharge time based upon that as well as the readings it receives. The discharge estimate isn't as accurate as I'd like, but that's probably due to my sporadic usage. The charge time, however, should be accurate since charge times are charge times are charge times.
Jeez- I should like contact the dev for a commission on the app at my rate.
Re-flashing the kernel might help, if A) killing GPS (except when, obviously, you're actually using it) and B) getting rid of those wakelocks (try Watchdog Lite-free) don't work. Eryigit's ROM, from what I remember, already has the Entropy kernel baked in
If you do some search through the past threads, you will find some discussions on this very topic.
Even though the battery performance of the device seems to be quite on par with other Android devices I have used, the amount of battery charge that is being reported is, a general guess at best. As it is, it only shows the charges and discharges only at 5% increments and on top of that, as OP stated, it seems to jump around a lot.... 100%-80% normal drain... jump down to 30% and hold... etc... heck! My device will show full charge and the moment I take off the charger, it drops to 80%... I have 4 5.0 devices and they all do that... I have stock GB, ICS and Custom GB roms and all are showing the same thing. I believe it has to do with the way the charge state is being reported... It must be a hardware glitch and I guess that is why no matter what rom you are on you will see this erratic battery % report.
I have stopped worrying about it since it does not seem to actually affect how the battery is performing.
Oh yes, I saw that post when I was skimming search results, but got fixated on the not charging above 80% part and didn't realize it was the same issue. I guess this is normal then. Thanks!
Regarding GPS: It actually doesn't seem to affect my battery life unless I'm using Google Maps, in which case the GPS flashes in the status bar and yes, the battery drains much faster. Confirmed regarding Eryigit and its custom kernel not having the same GPS wakelock issues. I went back to stock because I wanted something really light, what I ended up doing is using Titanium Backup to uninstall anything that showed up in the apps drawer or task manager that I didn't need. That made everything really nice and fast. Of course you could do the same thing with Eryigit. That might be my next move. Or maybe just try the custom kernel with the Stock ROM.

Yeah. I'm currently using Paranoid Android and it only charges to 80%. When I unplug and plug in the device it starts charging again.
I love the Galaxy Player 5.0, but it really bugs me the way Samsung so often completely abandons its customers past the point of purchase. Charging problems, bogus battery level readout, GPS off battery drain, screwy unusable GPS compass... and forget about Android updates. The US version never even got 2.3.6. I really wish there was a viable non-Samsung alternative to the 5.0, but there doesn't appear to be anything else out there that's like it.

Not just another "battery issues" thread

I have been meaning to post in here about how great my battery life has been, especially after seeing all of the threads complaining about it. I have been going home after a 9 hour day with 70-80% and even with extreme use, I have had no issues.
That being said, today my battery drained inexplicably fast for no reason. I checked my background apps and closed a few, but the battery drain persisted, so I rebooted.
Anyone else having this issue or know what causes it? This is the first incident I have had in almost a week. The last app I launched before this happened was Inrix traffic. Battery life has been beautiful, otherwise.

That's the fix I use. I now call my 920's battery life non-deterministic. It's great, except when it's not. When it's not, even if it looks like it should be because nothing is running, a reboot fixes it. Until the next time.
I would be shocked if there weren't an OS update to fix whatever process is going rouge and running away with the battery. Because it's something in the OS. Or at least its something the user cannot remedy, short of taking off and nuking the site from space.
I've noticed this a lot too. I killed a whole load of background apps and the battery life got a lot better. Then it got much worse again.
I believe my main problem is that I live in a low signal area. So I drain the whole thing in about 10-11 hours, even when out working the majority of the day.
One thing I have found is that the radios in the handset are very badly shielded compared to my previous handsets. This does mean that I can hear when the phone is sending out signals/utilising the radios. It does this a lot, even when it does have signal. It must consume a massive amount of power.
I get roughly 5-6 hours or so. Charger I bought on Amazon no longer does the trick (it's one that plugs into the cigerette lighter in your car and two USB outs). I have to bring with me the power cord and an inverter to keep it charged up so it makes it through the day.
I've got NFC and Bluetooth turned off, Wi-Fi on and the phone set to 3G mode. I get pretty solid battery life out of it.
When I feel the back of the phone getting warm, I reboot and it's good for awhile. I too would be surprised if there isn't an OS update to fix this issue.

I am heaving same issue with battery. Phone worked fine first 10 days and it started to be warm on the top back. Life of the battery can not last a day and i am a heavy user.
As somebody mentioned in comment to turn off this and that- i don't think so. I did not buy phone to keep everything off on it.
If in airplane mode. had couple pictures and few other things, this is what you get out of your battery.

Excellent. I'll just keep my phone in Airplane mode all the time! What was I thinking, leaving the cell radio on?
I've just had 2 great days life out of mine. Off charge at 6am and currently sat at 58% at 4pm. I've been streaming a podcast from the internet via bluetooth for 90 minutes and I've been tethering too, as well as all the usual stuff, so it's not like it's been sat idle all day. I've even been using Nokia Drive to get to work this morning (I teach at many different schools) whilst streaming media off the web and bluetoothing it to the stereo and it's not hit it bad. Seems very power conservative where internet streaming and GPS is concerned.
I have battery level for WP8 installed and it has a graph so you can see when the battery level is dropping off. I've noticed solid battery drain from running the Audible app which continues after the app is closed. Rebooting solves this. I have been working in an area with excellent signal recently though, that may have made a big difference. I get 9-10mbps on HSPA at the moment. I do, of course, have NFC turned off.
Hopefully Portico will be here soon and solve some of these power problems.
