Samsung Galaxy S23

What Reviewers Agree On

Genuinely compact flagship — 6.1" body 'frees you from awkward big phones and camera spec overkill' (Android Central)
Same Snapdragon 8 Gen 2 for Galaxy chip as the Plus and Ultra — no performance compromise vs the more expensive siblings
Same 50MP main + 12MP ultrawide + 10MP 3x telephoto + 12MP selfie as the Plus — the 3x optical zoom is a real step up from rivals stuck at 2x
Display brightness up 35% from the S22 to 1750-nit peak; 120Hz Dynamic AMOLED 2X stays sharp and vibrant
Adopts the Ultra's floating-camera design — cohesive trio look without the contour bump

Detailed Comparison

Battery & Charging

Samsung Galaxy S23

3,900mAh — the family's weakest point. Real-world ~5-6 hours of SOT typical (worsened by One UI 6/7), and only 25W charging means ~1h12m to full. The compact form factor's main cost.

3,900mAh battery — only 200mAh more than the S22, no 4,500mAh+ like the Plus. The smallest cell in the family.
Real-world: ~5-6 hours of SOT typical, comfortably a full day of moderate use, 1-1.5 days possible.
Battery life noticeably dropped after One UI 6 update — owner went from 5-6h SOT on 5G to barely 2h, recommends staying on Android 13 for best results.
Feb 2026 update real-world: ~4h SOT on Wi-Fi, drops to <2h on 5G — battery efficiency has gotten worse with time.
Charging caps at 25W (the Plus and Ultra get 45W): 0-100% takes ~1h12m on Samsung's 25W charger.

Samsung Galaxy S25+

What Reviewers Agree On

The Snapdragon 8 Elite for Galaxy delivers fast, fluid performance with noticeably better thermals than the S24+ — gaming sessions don't stutter and the phone stays cooler under load.
The 6.7-inch QHD+ Dynamic AMOLED 2X with 120Hz and 2,600-nit peak brightness is one of the best displays on any smartphone, full stop.
Battery life on the unchanged 4,900 mAh cell easily lasts a full day, with most reviewers ending around 25-40% remaining.
Samsung's seven years of OS upgrades and security patches is a best-in-industry commitment that justifies the long-term investment.
One UI 7 is Samsung's most polished software ever — the split Quick Settings/notifications shade, snappy animations and Circle to Search are genuine improvements.
Build quality is excellent and the body is meaningfully slimmer (7.3mm) and lighter (190g) than the S24+ despite identical screen size.
At $999 it's $300 cheaper than the S25 Ultra while sharing the chip, RAM, display tech, AI features and update window — it's the value pick of the S25 lineup if you want a big phone.

Deal Breakers

The camera hardware is entirely carried over from the S24+ (and S23+) — same 50MP main, 12MP ultrawide, 10MP 3x telephoto — and now lags rivals like the OnePlus 13 and Pixel 9 Pro that ship 50MP ultrawides and 5x periscope tele lenses at the same price.
Qi2 wireless charging is 'Qi2 Ready' only — the phone has no built-in magnets, so MagSafe-style accessories require buying a separate magnetic case, and third-party cases are hit-or-miss.
Galaxy AI features are guaranteed free only through the end of 2025, with Samsung hinting at a future paid tier and refusing to commit to pricing.
Virtually nothing has changed externally from the S24+ — same shape, same camera island layout, even the same colors-of-the-year feel. Reviewers from The Verge, Wired, Trusted Reviews and 9to5Google all note this directly.
The 3x optical telephoto is a clear weak spot at $1,000 — rivals at the same price now offer 5x periscope cameras that capture noticeably more detail at longer zoom ranges.

Samsung Galaxy S25+

Same 4,900 mAh cell as the S24+, same 45W wired and 15W wireless charging caps. The more efficient Snapdragon 8 Elite for Galaxy pushes real-world endurance comfortably to a full day with 25-40% remaining. Real charge time is ~75 minutes wall-to-100% on a 65W charger. The Qi2 Ready implementation without built-in magnets is the consistent frustration, and reviewers note that OnePlus 13's silicon-carbon battery and ~40-minute full charge time make Samsung look complacent here.

The 4,900mAh battery goes all day even with more pixels to light up — frequently ended a day with around 40 to 30 percent battery left and roughly five to six hours of screen-on time.
On several occasions the S25 Plus lasted over 24 hours on a single charge with at least six hours of screen-on time and 10-20% remaining — battery life can satisfy even demanding users.
A quick ten-minute top-up nets around 25%, 50% in 25 minutes, 75% in 40 minutes, and a full charge averages about 1 hour 10 minutes — fastest test was 64 minutes.
Pales in comparison to rivals like the OnePlus 13 which achieves a full charge in under 40 minutes — OnePlus 13's 50W magnetic charger is effectively faster than the S25 Plus on a 45W charger.
Qi2 is one of the most exciting features coming to Android in 2025, but the S25 Plus is Qi2 Ready only — no built-in magnets, so you need a separate magnetic case and third-party options are hit-or-miss.
Galaxy S25+ carries slightly better battery life than the S24+ — a full day with around 25% left over by the evening, versus the S24+ ending around 20%.
Connecting to a 65W charger, after 15 minutes nearly 45%, after 30 minutes 72% — Samsung's slower 45W cap is a deliberate trade for long-term battery health.
An r/Android upgrader said it best: 'I just wish it was using the new silicon lithium batteries that OnePlus has' — Samsung's choice to stick with the same 4,900 mAh cell is the most-criticized hardware decision in the lineup.
