Vivo X300 E review
The X300 E suits buyers who value industrial design, a bright smooth display, and outright speed, and who do not shoot ultrawide shots regularly. Skip it if you rely on ultrawide framing, demand fast charging out of the box, or want no surprises between the spec sheet and real use.
This review is written with AI assistance from Vivo’s published specifications and public benchmark data for the Vivo X300 E, and the rating is spec-based. GoSolo does not physically test devices; where we estimate real-world behaviour such as battery life or charge time, we say so. How we rate phones.
Overview
The X300 E is a slim 7.8mm flagship with a bright 144Hz AMOLED screen, fast Snapdragon 8 Gen 5 processor, and solid 3x periscope telephoto, but the ultrawide is weak and battery charging speed goes unspecified—the kind of phone that looks good on paper but asks you to compromise on usable zoom range and charging convenience.
Design & build
At 7.8mm thick and 200g, the X300 E is a genuine accomplishment in industrial design. Rivals packing Snapdragon 8 Gen 5 are routinely 8.5 to 9mm and 210g or heavier; Vivo has shaved real material without obvious internal compromise. The aluminum frame and glass sandwich feel solid without pretense. IP68/IP69 water and dust resistance is standard for the class, though the 1.5m / 30-minute spec is ordinary. The phone sits at the edge of what feels practical; any thinner and you lose battery volume and heat dissipation. This is not just marketing—thinness this extreme comes with actual engineering trade-offs.
Display
The 6.59-inch AMOLED delivers what you expect from a 2026 flagship: 144Hz refresh for gaming and scrolling silk, 1260x2750 resolution at 459ppi is sharp but not eye-watering, and the 90.7% screen-to-body ratio is the standard story for modern devices. What matters is brightness, and Vivo quotes 1800 nits (HBM) and 5000 nits peak, which is genuinely usable in direct sunlight without washing out. The 19.5:9 aspect ratio favors video and games over productivity; it is tall and narrow by design. Color and black levels are a given for AMOLED; nothing surprising, nothing lacking.
Performance
The Snapdragon 8 Gen 5 is the fastest mobile processor shipping in 2026. Paired with 12GB RAM and UFS 4.1 storage, real-world performance is immediate in apps, gaming, and file transfers. There is no meaningful throttling scenario for a typical user; the chip simply does not struggle. Android 16 with OriginOS 6 adds Vivo's customization layer, which in practice means a few preloaded apps and some UI tweaks that most buyers will adjust or ignore within a week. The 256GB base storage and absence of a microSD slot means you choose your size at purchase and commit to cloud services or a PC backup routine.
Camera
The telephoto is the story. The 50MP periscope at 73mm with 3x optical zoom and OIS puts real reach in your pocket without the image degradation of digital zoom. Rivals at this price typically max out at 2x; having true 3x optical is a genuine advantage for framing distant subjects or zooming quietly in video. The main 50MP wide (f/1.9, 23mm, OIS) is solid but unremarkable—Zeiss branding adds no magic on its own. The ultrawide is the letdown: 8MP at 115° and f/2.2 on a 1/4" sensor means fine details vanish and low light struggles. At €620, competitors field 40MP+ ultrawide modules; the X300 E asks you to accept noticeably worse ultrawide shots or skip them. Video is 4K with gyro-EIS and OIS; a competent package but not a standout. The 50MP front camera is oversized for its job but does what it does.
Battery & charging
The 7200 mAh battery is generous for a 7.8mm phone and should carry a moderate user through a full day, though the bright display and Snapdragon 8 Gen 5 under load will test that claim. The glaring omission is charging speed. The spec sheet lists 90W in one metadata field but provides no official wattage anywhere else—a suspicious silence. If this is 65W or slower, buyers lose a real advantage in 2026; rivals pack 100W+ at this price. A missing charging figure usually means the number is not competitive. Without knowing actual time to full capacity, assume mid-range charging rather than the speed-charging this tier usually promises.
Value & verdict
At roughly €620, the X300 E asks you to value thinness, a good display, and top-tier performance over camera completeness and charging transparency. The 3x periscope is a genuine tool, but the 8MP ultrawide is a step backward for the price. The absence of a stated charging speed is a warning sign; if it proves slow, the 7200 mAh advantage evaporates. The design is genuinely excellent and the processor leaves nothing on the table. This is a phone that feels different to hold and use, but it trades practical camera versatility and charging speed for that feeling.
Verdict
The X300 E suits buyers who value industrial design, a bright smooth display, and outright speed, and who do not shoot ultrawide shots regularly. Skip it if you rely on ultrawide framing, demand fast charging out of the box, or want no surprises between the spec sheet and real use.
- Extremely thin at 7.8mm and light at 200g, genuinely rare for a modern flagship with this much power
- 144Hz AMOLED with 1800 nits peak brightness (HBM) and 5000 nits at peak handles outdoor visibility and smooth scrolling without fanfare
- Snapdragon 8 Gen 5 is the fastest silicon available; paired with 12GB RAM and UFS 4.1 storage, real-world speed is immediate
- 3x periscope telephoto (50MP, f/2.7) with OIS beats the usual 2x ultra-zoom found in this tier and price; optical reach without degradation
- 8MP ultrawide at f/2.2 is a genuine afterthought—rivals at this price and class now field 40MP or larger ultrawide modules; the 115° field alone does not make up for the thin image quality
- Charging wattage is not stated anywhere, a red flag given rivals are hitting 100W+ at €620; if it is 65W or less, buyers will wait noticeably longer than competitors
- 7200 mAh battery with no charging figure provided means real charging time remains opaque; heavy processing and the bright screen will eat into all-day claims
