Samsung Galaxy A36 5G vs Xiaomi 15

Samsung Galaxy A36 5G

The 6.6-inch Super AMOLED display is the A36's strongest feature. Samsung's AMOLED expertise trickles down effectively here, delivering punchy colors and smooth scrolling that outclass most budget competitors.

• Super AMOLED display delivers rich, vibrant colors that punch well above the $299 price point
• 120Hz refresh rate makes the UI feel smoother than the processor sometimes allows
• FHD+ resolution is sharp enough for the screen size — text and images look crisp

Xiaomi 15

The 6.36-inch 1.5K LTPO OLED is sharp, vibrant, and incredibly bright at 3,200 nits peak (tested up to 3,593 nits HDR). Ultra-narrow 1.38mm bezels and high-frequency PWM dimming above 3,000Hz round out an excellent display package, though OLED smear at lower brightness is a noted concern.

• Peak brightness tested at 3,593 nits in HDR — among the brightest compact phone displays available
• Ultra-narrow 1.38mm bezels with excellent color accuracy in Original Color PRO profile
• OLED smear visible at lower brightness levels (0-70% range) — a recurring user complaint

Battery life is one of the A36's genuine strengths. The 5,000mAh battery combined with the efficient (if slow) processor means the phone easily lasts a full day and often stretches into day two.

• Excellent battery life — the combination of efficient chip and large battery means consistent two-day endurance for light users
• Even heavy users will get through a full day without anxiety
• 25W charging is painfully slow by 2025 standards — a full charge takes well over an hour

Xiaomi 15

A standout category for the Xiaomi 15. The 5,400mAh silicon-carbon battery is a huge upgrade from the Xiaomi 14's 4,610mAh, delivering 16+ hours of active use in GSMArena's tests and consistently 7-8 hours of screen-on time. 90W wired charging goes from 0-100% in about 50 minutes.

• GSMArena Active Use Score of 16:28 hours — excellent endurance for a compact flagship
• 5,400mAh silicon-carbon battery is a massive upgrade from the Xiaomi 14's 4,610mAh — real-world 7-8 hours SOT
• 90W wired charging does 0-100% in about 50 minutes; 50W wireless charging also supported
