# Notifications and Pushes

If you compare the battery impact of AyuGram and any other legit Telegram client, you'll probably see a difference, like 30% vs. 15%.

TLDR; download separate build with FCM pushes here if you have Play Store.

Tho it's worth to mention that these builds may work or not, depending on your ROM and installed GApps/MicroG. Check if this build works fine for you, and if it's not - revert to the original version.

In my personal experience, it works even better on devices with MicroG.

Some users say that on devices with MIUI .web version works bettter.

And well, they may contain more bugs than the original version.

Well, it's because of that, maybe annoying for you, notification in status bar. It helps AyuGram to be in a foreground and receive updates from Telegram server. If you disable it (not hide, but disable option AyuGram Push Service) in the preferences, most likely your system will kill the app. You can read more here about this problem.

You'd ask, like if other clients receive that pushes without working in the foreground, why can't AyuGram do like that?

There's a specific reason for that - Firebase Cloud Messaging. This is a service that keeps a background connection to Google services and receives updates from it, even if the app is closed. But it should be configured properly to work. You should have access to Telegram's application developer page, and provide keys for FCM to work properly. But hey, you didn't forget that we're using official keys and can't access it?

FCM has some kind of app verification that requests a token for receiving pushes. In short, it verifies a signature and package name.

And oh, actually, we bypassed both checks. But you should use another build of AyuGram, with the original package name.

Talking about package name, we provide two different APKs, with different package names. The one with org.telegram.messenger that pretends to be a Telegram from Play Store, the other one with org.telegram.messenger.web that pretends to be a Telegram from the official site. We do that to make it possible to keep AyuGram and vanilla Telegram on the one device simultaneously.

For example, if you download AyuGram with package name org.telegram.messenger.web, you'll be able to download a vanilla Telegram from Play Store and receive updates for it.
