I tested Truecaller on a Redmi Android phone for two days. The app opened normally, and the main Calls screen was easy to understand. Searching for a number, checking the call list, and opening contacts did not feel difficult.
During normal use, touch response was quick. Moving between the main sections was also smooth. I did not notice major screen glitches or broken buttons during simple testing.
Truecaller works in the background because it needs to identify incoming calls. This means it can use more phone resources than a basic contact app. Battery use can also change based on how many calls and messages the phone receives.
The phone did not become very hot during short checks. Longer use of call tools, messaging, and background services can make the phone work more, but I did not see serious heating during normal use.
What This App Actually Does
Truecaller helps you find out who is calling when the number is not saved on your phone. It also warns about spam and scam calls and lets you block unwanted numbers. The free version includes Caller ID, spam detection, manual blocking, and basic number search.
It also has a messaging section, call history tools, contacts, scam reports, and other phone features. Some extra tools, such as advanced blocking and removing ads, are part of the paid Premium plan.
Top 5 Features That Matter
- Caller ID: Truecaller can show the name of an unknown caller before you answer. This helps you decide if a call looks useful or unwanted.
- Spam Blocking: The app can warn you about spam and scam calls. You can also block unwanted numbers using its call controls.
- Number Search: You can type a phone number into Truecaller and check its available caller information. This is useful when you see a missed call from an unknown number.
- Smart Messages: Truecaller can handle SMS and identify unknown senders. It can also help filter spam messages on supported Android devices.
- Advanced Blocking: Users can block private numbers, foreign numbers, or numbers outside their contacts. Some advanced blocking choices are available with Premium.
Storage Space and Data Use
The current Android version is much bigger than the new Truecaller Lite app. Truecaller’s own comparison lists the main app at about 117 MB, while Truecaller Lite is about 10 MB.
A current Xiaomi app listing shows the main Truecaller package at 107.9 MB, while another current Android listing reports an APK download of about 89.58 MB. These numbers differ because package size depends on the store, device, and app version.
The total space on your phone can be higher than the download size. Cache and app data can grow as you use calls, messages, pictures, and other features, so there is no single fixed MB number for every phone.
Truecaller needs internet access for real-time caller information and updated spam data. Some SMS processing can work locally on the phone, according to Truecaller.
Permissions and App Safety
Truecaller asks for phone and call-log access for Caller ID and spam protection. It also asks for contacts access, while SMS, camera, microphone, storage, notifications, and drawing over other apps can be used for specific features.
Truecaller says contacts remain on your device and are not uploaded, stored, or shared with Truecaller. It also says SMS content is processed locally, while its privacy summary lists call data, device information, usage data, and other information that may be processed.
How It Compares to 2 Alternatives
Hiya is a direct choice for Caller ID and spam protection, with free basic protection and paid features. Samsung Smart Call, powered by Hiya on supported Samsung phones, can also identify spam and fraud calls without needing the full Truecaller app. Truecaller offers a wider set of tools, including messaging, number search, advanced blocking, and Premium services.
