Your Galaxy S25 Ultra heating while charging could be due to several reasons, especially since you're using an older A73 5G (25W) adapter instead of the official one. Here’s what might be causing the heat:

Possible Causes: Adapter Mismatch – The S25 Ultra likely supports 45W charging, but you're using a 25W charger, which might cause inefficiencies and heat buildup. Non-Compatible Charger – Even though it’s a Samsung charger, different models have different power delivery standards. Cable Issue – If you're using an old or non-original cable, it might not be handling power transfer efficiently, leading to heat. Fast Charging Generates Heat – Any phone heats up when charging fast, but it shouldn’t be excessively hot. Background Apps – If apps are running in the background, they can cause additional heat. Try charging in Airplane Mode or Power Saving Mode and see if it helps. Room Temperature – If your environment is hot, the phone might struggle to dissipate heat. Battery Health – If your battery is aging or defective, it might heat up more than usual. How to Fix It:

✅ Try using an official 45W charger and a certified cable.
✅ Charge in a cool environment and avoid placing the phone on soft surfaces.
✅ Turn on "Protect Battery" mode in settings to limit charge to 85% (reduces heat).
✅ Check for software updates – sometimes firmware issues cause heating.
✅ If the heating is too much, try charging while the phone is powered off.
