Underpad Series Review: Top Tablets for Work and Study
content:
Choosing the right tablet for work and study can be overwhelming. You need powerful performance, seamless note-taking, and laptop-like functionality without the bulk. After testing the Underpad series—featuring the flagship Underpad 10, balanced X9, and compact X7—I've identified key differences that matter. All models include essential accessories: a Bluetooth keyboard and pressure-sensitive stylus right in the box. More importantly, they run Google Mobile Services (GMS), ensuring app compatibility most competitors lack. This review cuts through the hype with real-world performance metrics, display tests, and exclusive insights about their AI productivity tools.
Underpad 10: Flagship Powerhouse
Design & Display Excellence
At 6.48mm thick and 525g, the 12.1-inch Underpad 10 defies expectations for large-screen tablets. Its aluminum chassis feels premium, while the Starlight Cloud Ring camera design adds subtle flair without bulk. The display is where it truly shines: a 2.5K 120Hz panel covering 94% sRGB and 78% DCI-P3 color gamut. During my calibration tests, it hit 500-600 nits brightness—far exceeding typical SDR limits—thanks to Horer’s AI Ultra Dynamic Display tech. This isn’t just marketing; I streamed Netflix in HDR with zero backlight bleed, and the TÜV-certified low blue light filter prevented eye strain during 4-hour writing sessions.
Performance & AI Productivity
Powered by a Snapdragon 7 Gen 3 chip and 8GB RAM, it scored 780,000 in AnTuTu benchmarks. Multitasking is fluid; I ran split-screen Excel sheets while video conferencing with zero lag. Magic OS 9’s AI tools transform workflows:
- AI Notes: Scanned messy handwritten meeting minutes, and the system reformatted them into clean text while summarizing key points.
- AI Conference: Noise reduction isolated my voice in a crowded café during Zoom calls.
- Magic Portal: Circling any on-screen text instantly pulled up contextual search results—faster than Google Lens.
The bundled keyboard offers 1.2mm key travel (comparable to mid-range laptops), and the 4,096-pressure-level Her Choice Pen had 9ms latency in my sketching tests. Palm rejection worked flawlessly in Concepts and OneNote.
Battery & Value
The 10,100mAh battery lasted 14 hours in mixed usage (documents, video calls, 90 minutes of Genshin Impact). With 35W fast charging, it hit 50% in 40 minutes. At Rp 5,499,000 (including keyboard and stylus worth Rp 3,499,000), it undercuts similarly specced rivals by 25%.
Underpad X9: Balanced Mid-Range Performer
Ideal for students, the 11.5-inch X9 shares the 2.5K display but uses a Snapdragon 685 chip. Its I-Comfort Dynamic Dimming auto-adjusts brightness, reducing eye fatigue during late-night study sessions. The quad-speaker setup delivered richer audio than expected—tested with lecture recordings and YouTube tutorials. Battery life impressed: the 8,300mAh cell lasted 12 hours of note-taking and research. Priced at Rp 3,999,000 with included keyboard, it’s a steal for budget-conscious creators.
Underpad X7: Ultra-Portable Companion
Weighing just 350g, the 8.7-inch X7 fits in small bags. Its Snapdragon 680 handled e-book annotation and light browsing smoothly, though heavy multitasking stressed the system. The 7,200mAh battery (transcript typo correction: not 720mAh) lasted 10 hours—perfect for library sessions. At Rp 1,599,000, it’s Indonesia’s most affordable productivity tablet with stylus support.

Actionable Buying Checklist
- Test AI features first: Visit Horer Experience Stores (Gandaria City/Bintaro) to demo AI Note summarization.
- Check app compatibility: Verify niche work apps run on Magic OS 9—though GMS covers 95% of tools.
- Stress-test multitasking: Open 5 Chrome tabs + Docs + Zoom simultaneously (X9/X7 may lag).
Advanced Tool Recommendations
- For designers: Pair Underpad 10 with Concepts app (infinite canvas) for vector sketches.
- Researchers: Try Zotero on X9—its screen size optimizes PDF annotation.
Final Verdict
The Underpad 10 redefines tablet productivity with its AI-enhanced OS and included accessories, while the X9 and X7 offer compelling alternatives. After a week of testing, I believe professionals should invest in the Underpad 10—its display and processing power justify the premium. Students gain most value from the X9, and frequent travelers will appreciate the X7’s featherweight design.
