Hi.
While playing games my Xperia Play produces lots of heat. The back of the phone, and the gamepad feels really warm.
I checked the temperature with Battery Monitor Widget and when I don't use the phone it stays around 25-30 degrees Celsius, but when I play games (even 2D ones) it goes up to 38-40.
Is this a normal thing or there's something wrong with my battery ?

I can confirm this happens. Basically it is using more charge, therefore as a side effect of that it produces more heat from the chemical reaction. Same thing when you have it charging.
It isn't horrible, but try not to let it get too hot as it may shorten the lifespan of the battery.
So this is true for all xperia plays that after some time of gaming the phone will be really warm ?
The phone will get warmer, of course... but 40 degrees is not excessively hot. It feels warm in your hand, but it's not dangerous. A dangerous temperature would be close to 50.
The highest temperature that I had was 44 degrees after a long Nova 2 session.
I am a bit worried by the fact that while browsing the net through wifi the battery heats up to 38 degrees, but it's okay as long as it's less than 50 :> ?
Thanks for the help.
I'd say if it goes above 46 or 47 you just switch it off for a while. Not only because you don't want to overheat it, but because running the phone on higher temperatures reduces battery life (higher temperature means higher resistance to conductivity for metals).
Thanks for the into that it's perfectly normal for the phone to feel warm.
Have you ever reached 50(or that 46,47) degrees on Xperia Play or any other phone ? What app made your battery that hot ?

My former phone, the Galaxy S had HUGE issues with temperature while using 3G. Every time I toggled it on, the phone became awfully hot and the battery drain skyrocketed. I got it on 53 degrees once, since it was in my pocket. I was a bit scared, but the phone resisted it. Still, it wasn't pleasant.
The advantage of the Xperia Play being bulky and plasticky is that it's hard to bring it to extreme temperatures. If it's hard to make it hot, it has a positive impact on battery life as well.

Yea, this happens to me all the time. When using anything that drains my battery it heats it up as well.
All batteries release heat as current passes through them. When the phone is idle, the heat released is low enough your hand doesn't feel it. As the current increases while gaming, so does the heat.
It's nothing to worry about. The batteries are designed to handle heat without being damaged.
Especially since android devices are becoming more popular in places like india, where there's a lot of ambient heat.

Hey, I got my nexus 4 a couple days ago and have been messing around with it. I recently went back to stock and flashed franco kernel. I just played about ten minutes of Modern Combat 4 and my battery fell more than 10%!!! I think it was fine when I first got it so I hope I didnt damage my battery somehow. I did run like 3 mins of stresstest but I did not let my battery temp get higher than 40 degrees Celsius. My CPU temp did hit 70 though and throttled. Im really baffled as what to do... When playing MC4 my phone did not feel overly hot and when I checked my battery temps were around 35 degrees.

Gaming on a cellular device does eat up a lot of juice. Especially a game with great graphics like modern combat. I see you have red lines in your battery status. You must have bad signal or no signal from where you are. That drains battery power as well as it tends to draw more power to try to connect to the cell tower/antenna. (Just in case you didn't know)

I actually dont have a sim card in yet, since I just got the phone.
I've found the phone goes longer between charges since I've broken it in a bit - a few months' charge / recharge cycles (plus expecting to need to recharge after a heavy gaming sesh) have helped

Even without the SIM card it still scans and connects to the wireless network (or attempts to when there is no signal), any cell phone with or without an active plan legally must be allowed to complete a 911 call.
Just one app's performance is not sufficient to determine the state of the battery. Run the phone for a couple of days (without the game) and get a better idea of the overall performance. I'm not sure what franco's kernel gets for battery life overall, but I'm sure other user's have posted in the thread, compare your use vs life to theirs.
In the future, don't stress test your phone. And don't double post threads please.
But my main question is, should it fall so steeply during a 10 min gaming session? If it kept falling like that I doubt il even be able to get an hour gaming time...

That's normal for MC4. I can completely drain my phone in about two hours playing that game.

Alright thanks. The first day I got it I was able to get 4 hours screen time since I was just installing stuff and readying it up. I just got worried that from my stresstesting for 3 mins I might of damaged the battery somehow. I wont be stresstesting again lol.

That's pretty damn good. Game's tend to use up quite a bit of battery, even games that aren't that intense, I get about 4% drop in ten minutes of playing Plague Inc. I don't imagine that game is nearly as CPU/GPU heavy as MC4. Of course I tend to have screen brightness higher, so that burns juice too.
Dear Friends and Community,
I recently acquired the S4 with moderate excitement. I already had a S3 and I was very happy with it but I had the option to get an S4 after extending one of our contracts so I went for it and gave my S3 to my wife - she's very happy with it now But i am not very happy with my S4 for 2 reasons:
- Extensive heat generation (36-47C) while surfing, watching videos, natigating calling etc.
- The heat seems to originate from the top portion of the phone on the back as well as the front side around the camera. it is uncomfortable to hold it against my hear on call
- My S3 did not heat up this much or this often. I also did not have any battery charge cliffs or jumps with my S3.
- As the device heats up, the battery drains INSANELY fast. Also I've noticed a disruptive and sudden battery discharge. As I charged my device for the frist time to 100% moments later the battery level jumped from for example 95% to 82% in one second. Is this due to battery calibration issues (because the device is new and the battery has not been charged many times yet) or is this something that can be considered a hardware flaw of the battery or device? I could be watching a video at medium brightness and my battery would go down by 1% each 2 minutes.
Sometimes during use and especially when it heats up some percentages are skipped while discharging (95%, 93%, 89% without sequencing down one by one but rather as 'chunks' of battery loss. ) did you exhibit similar behavior on your phone? Are these battery 'jumps' tied to the heat development?
And now the main questions: Should I return the device and exchange it against a new one or should I wait until Rom development or a patch tackles the problem ? I've already installed a recent OTA from Samsung and hoped the problem would vanish but no luck.
I'd be thrilled to hear your Opinions.
Best,
Thomas
Ive also noticed heating up and fast battery discharge, not one full day of normal usage, my s3 lasted at least 2 times longer. i hope it will pass as i finish 3 times battery charge discharge. for now im excited with camera quality and benchmarks scores i love this phone already, its still plastic but i dont care, with every phone i use silicon or other cases, for s4 i bought original samsung case with plastic back rounded by rubber.
In few days if overheating and fast discharge will not pass on its own i will flash firmware again with kies (repeir mode) and reset all settings.
I also experienced the same issue, its getting hot not warm while doing normal tasks... Dear Thomas u have see temp. in between 37 to 47 but my phone heats upto 55c while gaming... now my phone is with samsung service center, but i am not sure they will replace it with new one as their policy allows replacement only within seven days from the date of purchase and i bought it 27th April itself, just next day of launch. Now i am thinking that why the hell i rushed to buy it. i should have waited for user reviews...
And BTW flashing original firmware doesn't help. Because people at service center had done that and given my cell back to me, but that issue was still there so submitted it again to the service center.....
Are you guys getting these temperature readings using e.g. Battery temperature reading of Cool Tool?
My battery temperature as reported by cool tool never got above 40C but it felt quite hot to the touch already And I am not using any case on it...
I have a case arround it. I will play some games later to see where the temp peaks. but I think it will also be around 50 because it already gets pretty warm doing basic stuff like watching videos or using viber to call.
It feels like this is a problem for all S4's out there.
Check out this video at min 3:25 http://www.youtube.com/watch?v=aUx40kXZF5s (Steep drops in battery)
I really don't want to send in my device for no reason because I will most probably get a refurb or even a device with more problems.
I just want to know if other people have experienced similar issue.
You can check with the app called BatteryGraph and see if sometimes a few percent are skipped down the graph.
It would be great if someone did this for me
Same here with the heat. I undervolted -37,5mV and underclocked 300MHz, now everything is fine
Benchmarkscores are a little worse, but tbh, I really don't care. No current app or game is gonna use it anyway. Seems like a waste of battery life to keep the 1,9GHz clock speed.
Did the same with the Galaxy S2 I owned, which became quite hot too. Samsung has a tendency to overclock their chips just to outperform every other phone on the market, but the truth is, there is virtually no benefit in keeping the maxed clock speed in everyday use, other than doing benchmarks all the time ...
I'm having heat issue. phone heats up to around 100 during normal usage (texting, web browsing, social media) and unsuprisingly gets much hotter during games or youtube, around 105 F. Those temps are from a batter app, and the hotspot on the phone feels like it is up around the dimple. Certainly feels hotter than 105. Not so sure it is the battery causing a majority of the heat .... Still have a few days to return/exchange at best buy, so any advice is appreciated
No restarts due to heat yet. Have rebooted in safe mode, seems somewhat better after watching a 10 min youtube video... Can actually play fallout shelter in safe mode somehow, and the heat isn't as bad in safe mode as it is regularly. Temp stays around 100 F. Any way to see if it is an optimization issue without a factor reset and reinstall?
neglected to mention - this all happens while connected to wifi
Any phone that I've owned that I felt was to hot i exchanged it. It's paid off every time to do so. Good luck.
Mine was very hot
I dropped it off at Fed Ex to send it back a few minutes ago. I liked it a lot, but it was hitting 112 F within 5 minutes of browsing chrome/Facebook/Twitter. I've never had a phone get hot like that, unless I playing a game for an hour, or watching back to back to back videos over the LTE.
I could have exchanged it, but I will wait for the Nexus 5 and then make a decision of if I will order a new one or the Nexus.

So anyone else having this same issue?
To be honest, I've only had the Moto X heat up when I first got the phone and was downloading apps. And even then it didn't get as hot as my M8 did on a regular basis. I am not having any heat issues at all surprisingly.
I'd exchange it! I've used mine constantly even while being charged up by the turbocharger and I've never had it get uncomfortable to hold due to heat. That's browsing & playing games like order & chaos 2
I have a feeling that my battery life is way less than it should be. I have a Zerolemon 10,000 mAh battery. Most days I don't use my phone much during the day, except for playing a game for maybe a total of 1h 30m throughout the day. Latest one I've been playing is Fallout Shelter.
So in a full day, 5:40am to 7:00pm, I'm down to literally 20%. It feels like I have a stock battery.
Anyone else experience the same issue? I'm afraid my battery may be defective.
You should check the overall SOT. You should get around 10 hours of SOT with that battery. Of course, if the game is very demanding, the battery will drain much faster., as both the CPU and GPU will use more power.
Normally it should go down 1 % every 10 minutes of SOT (normal usage like browsing) and about 1% every 3 hours of idle.
Yesterday I got about 25 % life, today so far I'm at 55 %. I have not played the game since day before yesterday. You must be right about the demand of the game. The note 3 seems to have a very demanding chipset. Even my 10,000 mAh battery cannot keep up with its demand.
My stock battery gives me arround 4.30h Sot on wifi almost min brightness. Is it normal or defective ?
Firmware is 4.4.2
I'm starting to think this is normal usage on our phones. Today I managed to figure out part of my crazy battery usage. It has to do with a kernel wakelock. Bluesleep is the culprit, causing the phone to never go into deep sleep. I followed the guide in the description of this video and it has allowed my phone to enter deep sleep. I've also been using Juicedefender to manage WiFi, Mobile Data and Bluetooth. With all of this in mind I managed to keep my battery usage in check since a few days ago.
In the picture below you can see the list on the left, and how long each condition has lasted.

It's normal.
What is this eating my battery. Every time its available , i monitor cpu usage and i find it at 100% .happens every few days. A reboot fixes it temporarily
