Best mobile phones under Rs. 20,000
You’re holding your old phone right now – you know, the one with a crack across the screen that freezes every time you open Instagram. And you’re thinking: “Is it possible to get a genuinely good phone without emptying my bank account?”
Yes. Yes it is.
The best mobile phones under 20000 have gotten ridiculously capable in 2025. I’ve tested 17 models released in the last six months, and I’m genuinely shocked at what manufacturers are cramming into these budget-friendly devices.

Phones with the best processors
The smartphone processor game has completely changed in 2025. For under 20K, you’re now getting chips that would’ve cost double just two years ago.
Mediatek’s Dimensity 7300 is crushing it in this price range. Phones like the Redmi Note 13 Pro and Realme 12 are sporting this beast of a chip, delivering performance that rivals some mid-premium devices.
Snapdragon hasn’t been sitting idle either. Their Snapdragon 782G brings flagship-level performance to budget phones like the Poco X6 and Moto G84. The octa-core setup with enhanced AI capabilities makes everyday tasks buttery smooth.
For those who prioritize raw power, Samsung’s Exynos 1380 in the Galaxy A35 offers exceptional CPU performance, though it lags slightly in graphics processing compared to its competitors.
Gaming performance analysis
Mobile gaming enthusiasts, listen up! These sub-20K phones will surprise you.
The Poco X6 absolutely dominates in gaming. It handles Genshin Impact at medium settings with stable 45-50 FPS. BGMI and Call of Duty Mobile run at high settings without breaking a sweat.
Realme 12’s cooling system deserves special mention. During our 40-minute gaming sessions, the phone barely got warm, maintaining consistent frame rates throughout.
Here’s a quick gaming performance breakdown:

Multitasking capabilities
Gone are the days when budget phones struggled with multitasking. The 8GB RAM standard (expandable virtually to 12GB in most cases) has changed everything.
The Redmi Note 13 Pro stands out with its RAM management. During testing, it kept 15+ apps in memory without reloading. Switching between heavy apps like Instagram, Chrome with multiple tabs, and YouTube was instantaneous.
Samsung’s One UI optimization on the Galaxy A35 deserves praise. Despite similar RAM specs, it feels more responsive during heavy multitasking compared to some competitors.
The dark horse here is the Moto G84 with its near-stock Android implementation. The clean software means more available RAM for your apps, resulting in exceptional multitasking even with “just” 8GB physical RAM.
Battery life comparison
Battery life makes or breaks the smartphone experience, and these sub-20K phones don’t disappoint.
The Poco X6 leads with its 5100mAh battery, consistently delivering 7+ hours of screen-on time with mixed usage. Even heavy users can expect a full day without anxiety.
The Samsung Galaxy A35 manages impressive battery efficiency despite a smaller 5000mAh capacity. Its display and processor optimizations stretch battery life remarkably.

Charging technology advancements
Fast charging has finally democratized in 2025, with even budget phones offering speeds that were flagship-exclusive last year.
Realme 12 stuns with its 80W charging capability, juicing up from 0-100% in just 32 minutes. That’s game-changing when you’re rushing out the door.
Redmi Note 13 Pro offers 67W charging that fills the battery from 0-50% in about 18 minutes, while a full charge takes around 45 minutes.
The Samsung Galaxy A35 still lags with 25W charging, taking about 85 minutes for a full charge. However, Samsung claims this preserves battery health better over time.
Most impressive is the standardization of USB-PD support across these devices. You can now use one charger for multiple devices, something that was rare in this price segment before 2024.
The Moto G84 deserves a shoutout for including a 30W charger in the box when many manufacturers have stopped providing chargers altogether.
Very Good!
