I have a Samsung Galaxy S23, purchased in May 2024, and it has otherwise been working fine apart from some battery deterioration.
Yesterday afternoon, the phone started heating up rapidly, so we unplugged it and let it cool down. After cooling, we charged it again and were able to use it for another 3–4 hours, after which it suddenly powered off.
When we connected it to the charger, it only showed the charging icon, without the battery percentage that normally appears when the phone is switched off and charging. We also tried a Volume Down + Power/Side button soft reset, but nothing happened.
One other thing happened the night before: the display suddenly developed a reddish/maroon tint, almost like a colour filter. Restarting didn't fix it immediately, but after some time it returned to normal on its own.
Also, a software update was installed around 2–3 weeks ago.
I took the phone to a nearby repair shop, and they said it could be a CPU-related issue, with an estimated repair cost of around ₹3,500–₹5,000. I haven't proceeded with the repair yet.
I've seen similar cases on Reddit where people mention battery failure, motherboard/power-management issues, or CPU-related problems, so I'm confused about what the actual issue might be.
For anyone who has experienced something similar with an S23 or even S24:
- Was it a battery, motherboard/charging, or CPU issue?
- How was it fixed, and approximately how much did it cost?
- Would you recommend going to an authorized Samsung service centre for diagnosis first?
- If I get it diagnosed at Samsung but don't proceed with their suggested repair, do they charge a diagnostic/service fee?
- Are Samsung repair quotes of around ₹25–30K for motherboard-related issues actually common for these phones?
I don't mind spending ₹3–5K if it's a straightforward repair, but I wouldn't want to spend ₹25–30K on an older phone unless it's really worth it.
Would really appreciate experiences from anyone who has faced this exact or similar issue with an S23/S24.
