I recently noticed that my Samsung Galaxy S255 has been constantly heating badly and this has been happening mostly because of a trading app I use. I don't game, and don't do a lot of YouTube. My refresh rate is set at 60 even though the phone is capable of 120 HRTZ.
my display is always on the low and most of the settings I have to optimized better performance and manage heat is still on and get the overheating gets over 40 degrees. When it gets this hot it knocks out 5G, and the Internet becomes slower.
I use this trading app for over 10 hours daily and it's I don't think I want to stop. Battery cannot even charge when the phone is hot, and 90% when in usage.
I have done a few research. Samsung claims it can get up to 90 degrees without damage to the phone or battery, but this phone is a bit over $700 at that current exchange rate and I cannot even afford to not take care of it as it's not cheap. I used the previous mid-range device which I purchased for 250$ in 2021 for 4 years and it was a very great phone.
It actually handled heat better than this one, and I understand that this current device is flagship, yet I think for the processor, the thermal management should have been better, and Samsung hasn't done a good job in this regard.
I'm actually wondering what heavy usage that including gaming and YouTube, but I can't imagine having a hot phone that doesn't work or is fully optimized because of its temperature.
This is probably one aspect I don't like about this device, but every other aspect has been mind-blowing.
However since Samsung claims it is not going to do a damage to the phone, I think this is one consolation and that means it's actually built to handle heat, just not building for thermal management. iPhones had these issues especially from the iPhone 12 downwards and they did it differently with the subsequent generations.
Samsung still struggles with this.
In reality Samsung is the only brand actually doing the best job of actually utilizing Android. Personally I feel that iOS is limited, and if that weren't the case, I'd be using an iPhone.
iPhone has also fixed the terrible battery they use to have. They did this starting from the iPhone 15, and only thing Samsung holds is the fact Android is a more accessible operating system with apps and tools. I'm a huge Samsung lover, you can't better a better Android OS than the ONEUI and this is just the truth.
How do you handle a heating phone? I mostly prefer to put it on ice water.
