Galaxy S20 Plus vs Galaxy S23: which is better to own and fix?

We compare Galaxy S phones the way a repairability guide should — not just cameras and benchmarks, but what breaks, what fixes cost, how available parts are, and which chassis is less painful when real life happens.

Quick take

Pick Galaxy S23 if you care about stronger parts availability (excellent) and stronger overall shop rating (4/5). You're still in Android flagship repair territory, but the ownership gap shows up the first time you crack a screen or need a battery.

If you're choosing purely on sticker price, open the repair pricing links below for each model before you commit — a “cheap” used phone with a bad parts story is an expensive hobby.

Spec & repair snapshot

Use the comparison table for release year, chip, display, repairability, parts, and the failures we see most. The sections below explain why those numbers matter for this specific pair.

Ownership economics

Repairability is a tie at 6/10. Labor surprise will feel similar on both; pick on parts availability, used price, and which failures each model actually sees.

Galaxy S23 has excellent parts availability vs good for Galaxy S20 Plus. When a part is scarce, downtime stretches and shops quote more cautiously — that alone can decide a used purchase.

Our editorial ratings sit at 4/5 (Galaxy S23) and 3.5/5 (Galaxy S20 Plus). Those scores blend repair reality with day-to-day ownership — not launch-day hype.

Generation gap

Galaxy S23 (2023) vs Galaxy S20 Plus (2020) — 3 years apart. Plan for a real chip bump and longer support on the newer phone, plus a higher used-market floor.

Chip, display, and daily feel

Galaxy S23 runs Snapdragon 8 Gen 2 while Galaxy S20 Plus runs Snapdragon 865 / Exynos 990. For most owners that matters less than battery health and screen condition after two years. Displays differ: 6.1–6.2" Dynamic AMOLED 2X, 120Hz vs 6.2–6.7" AMOLED (Plus/Edge). Bigger/brighter panels look better — and cost more when they crack.

What actually breaks

Both phones share familiar shop traffic: Battery degradation; USB-C / charging port wear; Screen cracks from drops. Budget for those before you buy either used unit.

Which should you buy used?

1. Check battery health (Settings → Battery and device care) before either model
2. Ask about prior screen, back glass, or charging-port work — quality varies wildly by shop and part grade.
3. Price the #1 failure on each model using the linked repair pages before you negotiate.
4. Inspect for moisture indicators and bent frames — frame damage turns “simple” jobs into housing swaps.

Because these are 3 years apart, also check whether the older phone still gets security updates you care about — a cheap chassis that won't get patches can cost more in risk than it saves in cash.

Repair cost & downtime (shop perspective)

| Factor | Galaxy S23 | Galaxy S20 Plus | |--------|----------------|----------------| | Repairability | 6/10 | 6/10 | | Parts availability | excellent | good | | Typical first shop visit | Battery degradation | Battery degradation | | Second common issue | USB-C / charging port wear | USB-C / charging port wear | | Editorial rating | 4/5 | 3.5/5 |

Higher repairability and stronger parts availability usually mean fewer “we need to order that” delays and less labor surprise on common jobs.

Software & resale runway

Galaxy S23 (2023) will generally outlast Galaxy S20 Plus (2020) on One UI and security updates, but the used price gap often swallows that advantage. If both phones are already several years old, condition, battery health, and prior repair quality matter more than the generation gap on paper.

Who should pick which?

• Choose Galaxy S23 if you want balanced Galaxy S flagship, plus similar repair difficulty.
• Choose Galaxy S20 Plus if you specifically need large-screen Galaxy S with premium features and the used price leaves room for a repair cushion — even if overall ownership tilts the other way.

When to skip both

Skip this matchup entirely if either unit has an unknown repair history, a swollen battery, or a cracked OLED with no price adjustment — those problems erase any “winner” on a spreadsheet. Get a quote on the exact failure first.
