TCL 503 review
This phone suits someone on a strict budget who will use it for straightforward calls, texts, and light internet—and who is willing to live with a dim, low-res screen and carry a microSD card. Anyone wanting a better display, snappier performance, or a camera that does more than basic snapshots should spend the extra 50 EUR on a mid-range alternative."

This review is based on TCL’s published specifications and public benchmark data for the TCL 503, 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 TCL 503 is a straightforward budget Android phone built for calls, texts, and light browsing—nothing more. At around 100 EUR, it delivers what you'd expect: a big screen, all-day battery, and Android 14, but the display is dim and pixelated, performance is sluggish, and the storage requires a microSD card to be usable.
Design & build
At 185.5 g and 8.9 mm thick, the TCL 503 feels solid in hand—not light, but sturdy. Glass front and plastic back are standard budget fare; there's no premium finish, but it does not feel cheap or hollow. The fingerprint sensor on the rear is conveniently placed. Dual nano-SIM slots plus a dedicated microSD tray is a smart choice for users who need both cards and storage. In Space Gray or Midnight Blue, it looks inoffensive, if forgettable. For a 100 EUR phone, build quality is respectable; you will not feel shortchanged on materials.
Display
The 6.6-inch IPS LCD screen is where real compromise hits. At 720 x 1612 pixels and 267 ppi, text and UI icons are noticeably soft at normal reading distance—a step down from any mid-range phone released in 2024. The 20:9 aspect ratio is tall and narrow, good for one-handed use and vertical content, but the 350 nits peak brightness is a liability in sunlight. Outdoors, you'll squint or tilt the phone to see the screen clearly. Indoors and in shade, the display is fine for browsing and messaging, but video and photos lack the crispness you get from higher-resolution panels. If screen sharpness matters to you, this is a noticeable step back.
Performance
The Unisoc SC9863A running at 1.6 GHz is entry-level by any measure. Paired with 3 GB of RAM, the phone handles calls, messaging, and light web browsing without obvious lag. Social media, email, and simple games run smoothly on Android 14 Go Edition. But open more than two heavy apps at once, or fire up a demanding game, and you'll see stuttering and freezing. Video editing or any processor-intensive task is off the table. Multitasking is sluggish; switching between several apps introduces noticeable delays. This is a phone for people who use one app at a time and do not push it. For its price, the performance is what you pay for—do not expect miracles.
Software
Android 14 Go Edition is the right choice for this hardware. The lightweight OS keeps the phone responsive and maximizes battery life on a modest chipset. You get a full Android experience without bloatware dragging the device down. Updates and security patches depend on TCL's support, which is historically thin on budget devices, so do not expect long-term coverage. The Go Edition also limits pre-installed apps and background services, which is a practical benefit on a phone with only 3 GB of RAM. For a budget user, Go Edition is the sensible trade-off.
Camera
The 8 MP rear camera (upscaled to 13 MP) is adequate for snapshots in good light. f/2.0 aperture and autofocus help, but the small 1/4.0" sensor and 1.12 µm pixels mean details wash out and low-light shots are noisy. HDR and LED flash are present, but a budget sensor at this size simply cannot match phones one price tier up. The 5 MP selfie camera is better suited to video calls than selfies, though it does the job. 1080p@30fps video recording is a baseline feature; it works, but do not expect optical stabilization or advanced codecs. For casual snaps and documentation, it suffices; for anything beyond that, the results will disappoint.
Battery & charging
The 5000 mAh battery is the phone's strongest asset. On light use—calls, messaging, and browsing—expect a full day to 24 hours comfortably. Heavier use (video streaming or gaming) will cut that to around 12–14 hours, still respectable for this class. Charging speed is not specified on the sheet, but budget phones in this tier typically top out at 5–10W, meaning a full charge from zero will take 2–3 hours. There is no fast charging, but the large capacity means you do not need to top up as often. For a budget device sold around 100 EUR, all-day battery is a genuine strength and a practical reason to buy.
Value & verdict
At around 100 EUR, the TCL 503 is honest about what it is: a basic Android phone for people on a tight budget who need reliable calls, messaging, and web browsing. It does not pretend to be competitive with mid-range phones costing 150–200 EUR. The battery life and large screen are real perks, and Android 14 Go keeps the experience light and usable. The real friction points are the dim, pixelated display and the sluggish processor, both of which are limitations you will feel every day. Storage is tight enough to force a microSD card purchase. If you are buying a 100 EUR phone, you already accept trade-offs; the TCL 503 makes the right ones for its price, but it is not a phone that will surprise or delight you.
Verdict
This phone suits someone on a strict budget who will use it for straightforward calls, texts, and light internet—and who is willing to live with a dim, low-res screen and carry a microSD card. Anyone wanting a better display, snappier performance, or a camera that does more than basic snapshots should spend the extra 50 EUR on a mid-range alternative."
- 5000 mAh battery lasts a full day on light use, a genuine win for the price tier
- Large 6.6-inch screen is practical for reading and video, even if the resolution is low
- Dedicated microSD slot (up to 512 GB) means expandable storage without sacrificing the SIM slot
- Android 14 Go Edition keeps the phone responsive for basic tasks despite modest RAM
- 720p display at 267 ppi is visibly pixelated for text and UI; at 350 nits, it's hard to see outdoors without tilting the screen
- Unisoc SC9863A struggles with multitasking and any app heavier than social media; expect freezing in demanding situations
- Only 64 GB storage with roughly 40 GB free out of the box; a microSD card is nearly mandatory
