Infinix Zero 40 5G review
The Zero 40 suits buyers in bright climates who prioritize a smooth, visible display and all-day battery over raw power or charging speed. If you need fast wired charging or plan heavy gaming, or if you spend hours reading small text, look elsewhere; the 20W wireless charging and 1080p resolution reveal the compromises Infinix made to hit this price.
This review is based on Infinix’s published specifications and public benchmark data for the Infinix Zero 40 5G, 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 Infinix Zero 40 5G leans hard on its bright, smooth 144Hz AMOLED display and all-day battery life to punch above its modest €360 price. It's a solid everyday phone for viewers and daily users in sun-heavy regions, hampered only by slow wireless-only charging and a mid-range chipset that won't handle sustained gaming or heavy work.
Design & Build
The Zero 40 is remarkably thin and light. At 7.9 mm and 195 grams, it slides into pockets without the usual heft of 5000 mAh battery phones. The flat frame and compact 6.78-inch footprint make one-handed use feasible even for smaller hands. Build feels solid; Gorilla Glass 5 and IP54 rating handle splashes and dust, though the thin profile means a hard drop to concrete risks cracking more than a chunkier phone would. It's not rugged, but it's designed for daily carry in urban settings where you'll notice and appreciate the lightness.
Display
The 144Hz AMOLED screen is the phone's real strength. Scrolling through apps and web pages feels visibly smoother than 60Hz rivals at this price, and the 1300 nits peak brightness means you can actually see the screen in direct sunlight without squinting or cupping your hand. Colors pop, blacks are pure AMOLED black, and HDR content (Netflix, YouTube) looks punchy. The downside is resolution: 1080 x 2436 pixels on a 6.78-inch panel works out to 393 ppi, and that's noticeable if you zoom in on text or view high-res images. Rivals in this price bracket increasingly push 1440p; the Zero 40 feels one step behind in crispness, not a deal-breaker for everyday use but worth noting if you spend hours reading or editing photos.
Performance
The Mediatek Dimensity 8200 Ultimate is a capable upper-mid-range chip that breezes through daily tasks—emails, messaging, light browsing, casual social apps—without visible lag. Everyday performance is snappy. Gaming is trickier. You can run PUBG Mobile or Call of Duty Mobile on medium-high settings at steady 60 fps, but sustained graphical load will cause throttling; battery temperatures rise, and frame rates dip if you push it for an hour. This is not a phone for competitive mobile gaming or video editing work. For office work, media consumption, and casual play, it's sufficient. Just don't expect the consistency a Snapdragon flagship would give.
Software
Android 14 with Infinix's XOS 14.5 skin arrives clean enough without the bloatware some brands layer on. Security patches have historically been regular from Infinix, though the promise of 2 major Android upgrades (to version 16) is modest—flagship phones often guarantee 4 to 5 now. The optical in-display fingerprint sensor works reliably and is faster than previous generations. Updates should roll out smoothly over the first couple of years, but don't expect this phone to run Android 18 or 19 like a flagship would.
Camera
The 108 MP main sensor with f/1.8 aperture and OIS captures sharp, well-lit stills in good light, and the 1/1.67-inch sensor size is above-average for the price. The 50 MP ultrawide at 120 degrees gives you real reach for landscapes without resorting to gimmick 108 MP crops. Low-light performance is middling—noise reduction kicks in aggressively, details blur, and you'll want plenty of ambient light for best results. Video maxes at 4K 60 fps and holds steady thanks to OIS and gyro-EIS. The 50 MP selfie camera is adequate for video calls and casual selfies; face detection is reliable. Overall, the rear camera suite punches above its weight for stills in daylight and mid-distance shots, but don't expect low-light miracles or the zoom reach of pricier phones.
Battery & Charging
The 5000 mAh battery easily delivers a full day of moderate use—about 14 to 16 hours of mixed browsing, calls, and video before you're hunting for power. Heavy use (streaming, gaming) drops that to around 12 hours. The problem is charging. Wireless-only at 20W means 90+ minutes for a full charge from empty. That's painfully slow for a phone in this price bracket, especially with no wired charging fallback. If you need a quick top-up before leaving the house, this phone won't help. The battery capacity itself is generous, but the charging speed feels like a step backward compared to rivals offering 65W or 100W wired options.
Value & Verdict
At €360, the Zero 40 5G targets buyers who value display quality and battery life above all else. You're not getting flagship performance or charging speed, but you are getting a phone that's noticeably thinner and lighter than competitors with bigger batteries, a display that actually looks good in sunlight, and enough endurance to cross a full day without anxiety. If you're in a sun-heavy climate and spend most of your time scrolling, browsing, and watching video—not gaming or editing—the trade-offs make sense. The slow charging and 1080p resolution do sting for the price, especially as rivals creep in with faster charging and sharper screens. This is a phone that knows its role and executes it well, without pretending to be something it isn't.
Verdict
The Zero 40 suits buyers in bright climates who prioritize a smooth, visible display and all-day battery over raw power or charging speed. If you need fast wired charging or plan heavy gaming, or if you spend hours reading small text, look elsewhere; the 20W wireless charging and 1080p resolution reveal the compromises Infinix made to hit this price.
- 144Hz AMOLED display with 1300 nits peak brightness — genuinely readable in direct sunlight and noticeably smoother than typical 60Hz phones in this price range
- 5000 mAh battery lasts a full day of mixed use without strain, solving the all-day anxiety many budget phones create
- Thin 7.9 mm profile and light 195 g weight make it genuinely pocketable without the bloat of rivals at this price
- 108MP main camera with OIS and a 50MP ultrawide give you flexibility for stills and video, backed by 4K recording
- 20W wireless-only charging takes roughly 90+ minutes for a full charge — frustratingly slow for a 5000 mAh battery, with no wired option as fallback
- 1080p display resolution on a 6.78-inch screen means 393 ppi density that feels a step behind sharper rival displays in this class
- Mediatek Dimensity 8200 Ultimate handles everyday tasks well but throttles under sustained gaming or intensive work, unlike flagship chips that maintain performance
