The limit of characters that can be sent through a push notification

Question:

What is the number of characters that I can put in push notification? What is the number of displayed symbols? 

Answer:

Our service does not limit the number of characters used in pushes, however, there are limits for push payload size determined by Google and Apple - 4096 bytes and 2048 bytes correspondingly.

Regarding the limit of displayed symbols, here are the results for iOS and Android platforms:

Android - 13 lines limit(663 characters);

It should be emphasised that the number of lines depends on the Android version and specific layout used by the device manufacturer such as Samsung TouchWiz, Sony XPERIA UI, LG Sense UI etc.

iOS - 4 lines limit(178 characters).
However, an important feature is that on iOS you can extend notification with Force Touch with the possibility to scroll through the received text.
