WhatsApp Will End Support for Old Phones With Android 5.0 and iPhones That Do Not Update to iOS 15.1, Such as the iPhone 5s Without WhatsApp. Know Which Models Become Incompatible and Understand the Impact of WhatsApp KitKat – End of Support!
WhatsApp has announced an important update that will impact millions of users worldwide. Starting in October 2025, the app will stop working on phones with Android 5.0 (Lollipop) or lower versions, as well as iPhones with iOS prior to 15.1. This decision aims to improve security, privacy, and overall user experience, but will leave many old devices without access to the messenger.
If you own an older phone, it is essential to check the list of models incompatible with WhatsApp and understand what this change means for your communication. This article provides all the official information, based on reliable sources, so you can be prepared and know how to act.
Why Is WhatsApp Ending Support for Old Phones?
Today, WhatsApp is one of the most widely used instant messaging platforms on the planet, with over 2 billion active monthly users. To maintain a secure and efficient service, the platform needs to keep up with advancements in mobile operating systems.

Older versions, such as Android 5.0 or iOS below version 15.1, have technical limitations and security vulnerabilities that compromise the app’s functionality. WhatsApp cannot guarantee that the latest features, such as enhanced encryption, high-quality video calls, and new features, will work on such old systems.
Furthermore, maintaining support for obsolete systems increases the risks of vulnerabilities that can jeopardize user privacy. Therefore, the app periodically disables very old versions, as previously occurred with the WhatsApp KitKat end of support, when devices with Android 4.4 or lower were discontinued.
Phones Incompatible With WhatsApp: The List You Need to Know
The WhatsApp update will affect a number of widely used models, especially in Brazil and other emerging countries, where older devices are still common.
Android: Phones Incompatible With WhatsApp
All smartphones using Android 5.0 Lollipop or earlier versions will lose WhatsApp support. Among the most well-known and affected models are:
- Samsung Galaxy S4, S5 and earlier
- LG G3 and earlier versions
- Motorola Moto G (1st generation)
- Xiaomi Redmi 1S, Redmi 2 and similar models
These devices, although popular at their launch, do not support the latest updates of the Android system, making them incompatible with WhatsApp’s new requirements.
iPhone 5s Without WhatsApp and Other Affected Apple Models
Among Apple devices, all iPhones that cannot update to iOS 15.1 will lose access to the app. These include:
- iPhone 5s
- iPhone 6 and 6 Plus
- iPhone SE (1st generation)
These models do not have official support for higher iOS versions, so they will not be able to receive necessary updates to run WhatsApp from the new rule.
The Impact of the End of Support for Those Using Old Phones
The end of support for old phones represents a real challenge for millions of people who rely on WhatsApp for personal and professional communication.
Users who do not update their devices or operating systems will stop sending messages, making voice and video calls, in addition to losing access to all app functions. WhatsApp will stop working and display messages indicating that the device is no longer compatible.
Beyond the practical impact, there is also the risk of data loss if the user does not back up conversations before the block.
What to Do to Continue Using WhatsApp on Old Phones?
To avoid losing access to WhatsApp, it is important to take some precautions:
Update the Operating System If Possible
Check if your device allows updates to newer versions of Android or iOS. In some cases, it is possible to update to Android 6.0 or iOS 15.1, which will keep WhatsApp functioning.
Consider Replacing the Device
For many models, especially very old phones, the only solution will be to acquire a new device that supports the current versions of operating systems. Today, there are affordable options on the market that ensure support for several years.
Back Up Your Conversations
Before the app stops working, back up your conversations to Google Drive (Android) or iCloud (iOS). This way, you ensure that you can restore your messages on the new device without losses.
Historical Context: WhatsApp KitKat End of Support and Other Discontinuations
The current announcement follows the historical pattern of WhatsApp’s discontinuation of support for older systems. In 2023, the platform ended support for Android KitKat (version 4.4), forcing users to upgrade their phones to continue using the app.
This practice demonstrates WhatsApp’s ongoing need to keep up with technological evolution and focus on security and user experience. Although it causes inconvenience for those with old phones, it is a necessary measure to ensure service quality.
iPhone 5s Without WhatsApp: A Symbolic Case Among Old Phones
The iPhone 5s is a milestone in Apple’s history, being the first with a 64-bit processor and one of the brand’s most durable devices. Even so, in 2025, it can no longer meet WhatsApp’s demands.
With the end of support, the iPhone 5s without WhatsApp becomes a clear example of the limitations of older devices, even those considered premium in their time. Users of this model should consider migrating to more recent iPhones to ensure continuous access not only to WhatsApp but also to other applications and security updates.
Phones Incompatible With WhatsApp: A Global Reality and a Warning to the User
The discontinuation of support for old phones is a global trend in popular applications. WhatsApp, with its massive user base, needs to ensure that its features advance securely, which requires updated operating systems.
In Brazil, where many users still utilize old phones, this measure may significantly impact access to digital communication, especially for those without immediate resources to upgrade their devices.
The warning is clear: keeping track of updates in operating systems and planning device replacements are essential actions to avoid becoming disconnected.
Tips to Ease the Migration and Avoid Data Loss
Changing phones or systems may seem complicated, but some practices make the process smoother:
- Make periodic backups of WhatsApp to ensure data security.
- Use the official migration feature between Android and iPhone to transfer messages when necessary.
- Check for phones with a good cost-benefit ratio that offer support for many years.
- Consult your carrier or specialized stores for guidance on compatible models.
These actions help minimize disruptions and ensure that communication remains smooth and secure.
Update to Ensure the Security and Features of WhatsApp
The necessity of ending support for old phones is not just a technological whim. It is directly tied to user security.
Updated operating systems offer important fixes against digital threats, better performance, and support for new features, such as enhanced encryption and integration with other services.
Therefore, updating or replacing devices is recommended not only to continue using WhatsApp but also to ensure the protection of your personal data and privacy.
Preparing for the Digital Future With Modern Phones
The end of WhatsApp support for phones with Android 5.0 or iPhones with iOS below 15.1 reinforces that technology is in constant evolution. Staying updated with compatible devices is a way to ensure access to digital tools that facilitate life.
In addition to WhatsApp, other popular applications also require modern systems to function correctly. Therefore, investing in current phones is synonymous with being prepared for today’s and the near future’s digital demands.
