Telegram day and night mode and what makes it better against WhatsApp

Telegram handles themes more flexibly than almost any mainstream messaging app. Day mode (the default light theme) uses a clean white and blue interface. Night mode shifts to a deep dark background – either a true dark or a softer dark grey depending on your settings. But what makes Telegram stand out is that it doesn’t stop there. You can:

• Switch between light and dark manually or schedule it to follow your system/time of day automatically
• Use the built-in theme editor to customise virtually every colour element — chat bubbles, backgrounds, text, icons, UI accents
• Download and apply themes made by other users from Telegram’s own theme sharing community
• Set animated or static chat backgrounds independently of the overall theme
• On Android specifically, apply per-chat wallpapers with blur and colour tinting

WhatsApp also has a dark mode, but it’s essentially a binary switch; light or dark, and that’s it. You can change the chat wallpaper but the overall UI colour scheme is locked. There’s no theme editor, no community themes, no per-element customisation.

Where Telegram Pulls Ahead of WhatsApp More Broadly

The theme system is one piece of a much larger gap. The areas where Telegram genuinely outperforms WhatsApp include:

1. File sharing

Telegram allows sending files up to 2GB in a single transfer with no compression of photos and videos unless you choose it. WhatsApp compresses media aggressively and caps file sizes much lower, making it poor for sending anything high quality.

2. Multiple devices

Telegram works natively across unlimited devices simultaneously with no “primary phone” requirement. WhatsApp still tethers your account to a primary phone and the multi-device experience remains secondary and less stable.

3. Usernames and no phone number required

Telegram lets you set a username so people can reach you without knowing your phone number. WhatsApp requires a phone number for every contact, every time.

4. Channels and broadcast reach

Telegram channels can have unlimited subscribers and function more like a publication or broadcast platform. WhatsApp’s broadcast lists are capped and recipients must have your number saved to receive messages.

5. Bots and automation

Telegram has a mature, well-documented bot API that developers have used to build everything from news feeds and payment bots to games and automation tools. WhatsApp’s bot ecosystem is far more restricted and business-facing.

6. Message editing and deletion

Telegram lets you edit sent messages indefinitely and delete them for both sides with no time limit. WhatsApp added deletion for everyone but keeps a time window and doesn’t allow editing after sending.

7. Saved Messages

Telegram has a built-in personal cloud note feature (Saved Messages) that syncs across all your devices — essentially a personal inbox you can forward anything to. WhatsApp has no equivalent.

8. Storage and cloud

Telegram stores your full message history in the cloud by default, accessible from any device. WhatsApp stores locally and relies on Google Drive or iCloud backups, which are less seamless and can be lost.

Where WhatsApp Still Wins

To be fair, WhatsApp has two genuine advantages that keep it dominant in many markets. End-to-end encryption is on by default for all messages, whereas Telegram only encrypts Secret Chats end-to-end — regular cloud chats use server-side encryption, meaning Telegram’s servers can technically access them. For users who prioritise privacy above all else, this matters.

WhatsApp also wins on sheer network effect. In many countries – including much of Africa, Latin America, India, and Europe; WhatsApp is simply where everyone already is, and that matters more than features for most everyday users. Telegram does exit in all these territories though, but not as loud as WhatsApp.
