The App Most People Use Wrong
Telegram X is a separate client from the main Telegram app. It was built by Telegram's development team as a more performant alternative, written in Swift for iOS and Java/Kotlin for Android. The reason it exists is that the original Telegram app had performance issues on lower-end devices. X uses a different architecture that renders messages faster and consumes less battery. It also has a slightly different interface, with gestures you might not expect if you're used to the main app. I spent about three weeks trying to figure out why my media files weren't syncing properly between X and the main app. Turns out they use separate local databases. When I deleted the cache in X, the main app didn't see any change. The workaround was to go into Settings > Data and Storage > Storage Usage in both apps independently and clear them separately. Took me an hour to figure this out because there's basically no documentation about it.
Telegram X What Is It Used For Dissecting The Premium Messaging Apps Core Functions And Controversial Appeal
People download it for the speed. The main app sometimes stutters when you have large channels or groups loaded. X handles that better. But it's also where you go if you want certain experimental features that haven't made it to the main app yet. Things like the animated emoji reactions in beta, or the new story feature that's still rolling out. Here's what most people don't tell you about Telegram X. The notification system works differently. When you switch from the main app to X, you need to log in again. Your notifications won't carry over automatically. I lost about two days of messages because I switched devices and assumed X would pull my chat history from the cloud like normal. It does pull history, but your notification preferences reset to default. You have to manually set up which chats matter to you. I recommend going through your pinned chats first and marking the important ones as having priority notifications. It takes about ten minutes per device. The controversial part is that some people use X to bypass rate limits that apply to the main app. This isn't officially supported. If you're doing this, you're on your own. I know people who run multiple X instances for different purposes, but Telegram's terms of service technically prohibit this. The account gets flagged eventually. Usually within a few weeks of suspicious activity patterns.
To get it working properly, you download X from the official Telegram website or your device's app store. Not third-party sources. Then you log in with your phone number. If you already use the main app, you can export your settings first using the main app's export feature. This gives you a backup of your data, though it won't transfer directly to X. One thing to watch out for: the sticker packs in X are separate. If you have custom stickers downloaded in the main app, they won't show up in X. You need to re-download them. This is probably the most annoying part about switching. Takes about twenty minutes if you have a lot of custom packs. The premium subscription works across both apps. If you pay for Telegram Premium, it applies to whichever app you're logged into. There's no separate pricing for X. That said, some premium features like advanced analytics or the ability to create more channels might behave slightly differently in X. I noticed the admin tools in large groups have a different layout. It's not worse, just different. You get used to it after a week.

I'd recommend keeping the main app installed alongside X if you're serious about using this. They serve different purposes. Main app for everyday use. X for when you need better performance or want to test features before they hit the main client. That's really the core of it. Nothing more complicated than that.
