預算手機選購指南：記憶體漲價點揀 Budget Phone Buying Guide: Choosing Smart Amid Rising Memory Prices
2026 年買平價手機，很多人都感受到同一個現象：規格好似差不多，但價錢愈來愈高。主因不是「品牌變貴」，而是背後的 RAM 及內存晶片——AI 數據中心大量搶購記憶體，令 DRAM 與 NAND 成本急升，手機品牌要麼加價，要麼在 RAM／儲存／螢幕等位置悄悄「縮水」。在這個漲價周期，預算有限的你，更需要按真實使用者及場景去分配預算：買給家傭、買給老人家、以及自己用，優先次序都應該不同。
In 2026, many buyers notice the same trend in budget phones: similar specs, higher prices. The root cause is not simply brand pricing, but RAM and storage chips. AI data centers are absorbing huge amounts of DRAM and NAND, pushing component costs up and forcing phone brands to either raise prices or quietly downgrade RAM, storage, or displays. In this upcycle, budget-conscious buyers need to allocate their budget differently depending on who the phone is for: a domestic helper, an elderly family member, or yourself. Each scenario should prioritise different features.
行業背景：記憶體漲價如何影響平價手機？ Market Background: How Memory Price Surges Hit Budget Phones
多份產業報告指出，2025 Q4 至 2026 Q1 期間，手機用 DRAM 合約價按季急升，部分預測甚至指 Q1 合約價可升 90–95%；NAND 快閃記憶體亦錄得 50% 以上升幅。 Several industry reports note that from Q4 2025 to Q1 2026, mobile DRAM contract prices surged, with some forecasts putting Q1 price hikes at 90–95% quarter-on-quarter; NAND flash prices rose over 50% in the same period.
記憶體本身在預算手機的物料成本中佔比最高，可達整機 BOM 的 30–40%；價格一升，品牌只能在其它地方取捨：減 RAM、減內存、用較低規格屏幕或縮減相機。 Memory already accounts for the largest share of a budget phone’s bill of materials, at 30–40% or more. Once prices rise, brands are forced to trade off elsewhere: reducing RAM, shrinking storage, downgrading displays, or simplifying camera modules.
由於 AI 伺服器及高階 PC 對記憶體的需求仍然強勁，分析機構預期這個漲價周期至少持續至 2027 年——短期內等「回到以前的平價」並不現實。 Because AI servers and high-end PCs continue to drive strong memory demand, analysts expect this upcycle to last at least until 2027 — waiting for prices to “go back to the old normal” is unrealistic in the near term.
選購標準：漲價年代，預算應該點分配？ Buying Criteria: Where to Spend in a High-Cost Memory Cycle?
1. RAM：先看「實體 RAM」而非宣傳數字 / RAM: Focus on Physical RAM, Not Marketing Numbers
✅ 自用手機建議以 8GB 實體 RAM 作基本線；可以支撐 WhatsApp、地圖、外賣 App、網上銀行及社交媒體的同時使用。 For personal use, treat 8GB physical RAM as the baseline; this supports WhatsApp, maps, delivery apps, banking, and social media running together more reliably.
✅ 幫家傭買、老人家或基本用戶，4–6GB RAM 已經足夠；但若預算容許，6GB 優於 4GB。 For helpers, elderly users, or basic users, 4–6GB RAM is acceptable; if budget allows, 6GB is preferable to 4GB.
✅ 「擴充 RAM」或「虛擬 RAM」是把內存空間當作暫存，不能完全取代實體 RAM 的效能。 “RAM expansion” or “virtual RAM” uses storage as temporary memory and cannot fully replace physical RAM performance.
2. 內存：128GB vs 256GB 的取捨 / Storage: Choosing Between 128GB and 256GB
✅ 家傭、老人家或主要用於通話、WhatsApp、少量相片的用戶，128GB 通常足夠。 For helpers, elderly users, or those mainly using calls, WhatsApp, and a small number of photos, 128GB is usually enough.
✅ 自用、喜歡影相／拍片、儲存大量文件及下載內容的用家，建議直接選 256GB；配合 microSD 擴充更理想（若機型支援）。 If you shoot photos/videos, store many files, or download lots of content, go straight to 256GB; microSD expansion is even better if supported.
✅ 在記憶體漲價周期，兩個容量版本的價差可能比以前大，但長期使用下，較大容量的「壓力少」會更明顯。 During a memory upcycle, the price gap between capacities may be larger than before, but over long-term use, the reduced stress of a larger capacity becomes more noticeable.
3. 螢幕：尺寸、大字體、解像度一起看 / Display: Size, Text Legibility, and Resolution Together
✅ 老人家優先：大 MON＋大字體＋大音量。 6.7 吋以上螢幕配大字體模式，閱讀新聞、WhatsApp 及看影片更輕鬆。但是，6.9 吋螢幕配 720p 解像度，近看文字會有顆粒感；若預算容許，FHD+ 更適合長者敏感視力。 Elderly priority: big screen, large text, loud sound. A 6.7-inch-plus display with large-text mode makes reading news, WhatsApp, and watching video easier. A 6.9-inch display with 720p resolution can look grainy up close; if budget allows, FHD+ is better for ageing eyes.
✅ 自用人士可優先選 AMOLED＋FHD+＋高刷新率，視覺體驗與滑動流暢度都更好。 Personal users can prioritise AMOLED plus FHD+ with high refresh rates for better visual and scrolling experience.
4. 電池與快充：容量要配合充電速度 / Battery and Fast Charging: Capacity Must Match Charging Speed
✅ 5,000mAh 是現代使用的基本線；6,000–6,500mAh 對老人家、外勤或長時間睇片的用家更實際。 5,000mAh is a modern baseline; 6,000–6,500mAh is more practical for elderly users, field workers, or heavy video watchers.
✅ 只看「大電池」而忽略充電功率會帶來麻煩：10W 充滿 6,500mAh 需時甚長，45W 或以上快充在日常使用中更方便。 Looking only at “big battery” and ignoring charging wattage can be troublesome: 10W charging fills 6,500mAh very slowly, whereas 45W or above is much more convenient day-to-day.
5. 5G、NFC、VoLTE：按生活場景取捨 / 5G, NFC, VoLTE: Choose Based on Life Scenarios
✅ 5G：若主要在香港長期使用、預算有限，4G 機配更大 MON 或更大電池也可接受；5G 並非每個人都必需。
5G: If the phone will be used long-term in Hong Kong and budget is limited, a 4G phone with a larger display or battery can be acceptable; 5G is not essential for everyone.
✅ NFC：如需八達通、支付寶／微信支付、Google Wallet，必須確認有 NFC。 NFC: If you need Octopus, Alipay/WeChat Pay, or Google Wallet, NFC is non-negotiable.
✅ VoLTE／頻段：給家傭或會在海外使用的手機，必須確認目的地支援的頻段及 VoLTE。 VoLTE/bands: For helpers or phones used overseas, confirm supported bands and VoLTE in the destination country.
四大購機情境：不同人、不同取捨 Four Buying Scenarios: Different Users, Different Priorities
🧕 幫家傭買：愈平愈好，但要可靠通話 / Buying for Your Helper: Cheap but Call-Reliable
核心需求：價格低、雙卡、VoLTE 支援、基本 WhatsApp／通話流暢。
Core needs: low price, dual SIM, VoLTE support, and smooth WhatsApp/call performance.
不必追求高規格相機或極高刷新率螢幕；預算應主要放在「記憶體不太縮水」及「電池足夠」。
High-spec cameras and ultra-high refresh rates are not necessary; budget should mainly go to “memory that is not too small” and “adequate battery capacity.”
📱 家傭自己買：品牌熟悉感＋實用配置 / Helpers Buying Their Own: Brand Familiarity Plus Practical Specs
即使偏好特定品牌，仍建議先看 RAM、內存、電池、螢幕，再看品牌。
Even with a preferred brand, compare RAM, storage, battery, and display first, then consider brand.
接近 HK$2,000 的預算，8GB RAM＋256GB 內存＋大電池＋AMOLED 螢幕會比「純品牌」帶來較長期的使用價值。
Near HK$2,000, 8GB RAM plus 256GB storage plus a large battery and AMOLED display provides more long-term value than brand preference alone.
👴 老人家：大 MON、大字、大電、操作簡單 / Elderly Users: Big Screen, Big Text, Big Battery, Simple Use
優先大螢幕（6.7 吋以上）＋穩定續航（6,000mAh 左右），讓長者可以少充電、多睇片、多視像。
Prioritise a large display (6.7 inches or above) plus stable endurance (around 6,000mAh) so seniors can charge less and watch more video or do video calls.
解像度與字體同樣重要：大字體模式配 FHD+ 螢幕，閱讀舒適度明顯較好。
Resolution matters with text: large-text modes on FHD+ displays are noticeably more comfortable to read.
🙋 自用：RAM、內存、螢幕、電池要一起看 / Personal Use: Combine RAM, Storage, Display, and Battery
建議基本線：8GB RAM＋256GB 內存＋5,000mAh 以上電池＋AMOLED＋FHD+。
Recommended baseline: 8GB RAM plus 256GB storage plus a 5,000mAh+ battery plus AMOLED plus FHD+.
若預算有限，寧願在相機規格上退一步，也不要把 RAM／內存壓得太低；因為 RAM／內存會每天影響體驗，相機則是偶然使用才感受到差異。
If budget is tight, compromise on camera specs before cutting RAM/storage; memory impacts everyday experience, whereas camera differences are perceived less frequently.

快速選擇思路 | Quick-Pick Logic
💰 預算極限，用最少錢解決基本需求 / Absolute Lowest Budget: 選擇 4G 入門機，保留足夠 RAM／內存及電池，放棄不必要的高階相機或 5G。 Choose an entry-level 4G phone with adequate RAM, storage, and battery; skip unnecessary high-end cameras or 5G.
📞 幫家傭買或作備用機 / Buying for a Helper or as a Backup Phone: 先確認雙卡、VoLTE 及目的地頻段，然後以 4–6GB RAM＋128GB 內存作目標，重點放在「可通話、可上網、可用 WhatsApp」。 Confirm dual SIM, VoLTE, and destination bands first, then target 4–6GB RAM plus 128GB storage — the priority is "can call, can browse, can use WhatsApp."
👴 買俾老人家 / Buying for Elderly Users: 大 MON（6.7 吋以上）、大字體、更長續航比高性能更重要；FHD+ 解像度對視覺舒適度有幫助。 A big screen (6.7 inches or above), large text, and longer battery life matter more than high performance; FHD+ resolution improves reading comfort.
