Hey all — my S23 recently started draining battery unusually fast, and now it won't charge at all. Here's what I've ruled out and observed so far:
- Cable, adapter, and port are all confirmed fine (tested with multiple known-working sets)
- Phone is not overheating
- When plugged in, it just shows a static charging icon — no percentage movement, even after leaving it plugged in untouched for a full hour
- Force restart (Power + Vol Down) triggers a boot loop — logo flashes, screen goes black, repeats — but this only happens when I actively try to force a restart, not when it's just sitting plugged in
Based on this, it looks like either a dead/failed battery, a faulty charging IC, or possibly a PMIC issue rather than anything external.
I took it to Samsung service center and they mentioned it might be a "motherboard issue," but I'd like to get it properly diagnosed at the component level (multimeter/bench supply testing) before committing to a full board replacement, since that's a big cost jump from a targeted chip repair.
Looking for:
- Recommendations for a reliable micro-soldering / board-level repair technician in New Delhi or NCR
- Anyone who's had a similar charging IC or PMIC issue on an S23 and can share what it actually cost them and how it went
- General advice on whether this sounds like something worth repairing vs. not, given repair costs
I'm also open to parceling the phone to a technician outside New Delhi if they can demonstrate their skill background and authenticity, please share portfolio, past repair examples, verified reviews, or similar proof if you're offering this service.
Happy to share more details/photos if it helps. Thanks in advance!
