Truecaller now lets you hang up on scammers — on behalf of your family | TechCrunch

Caller identity platform Truecaller recently launched a new feature that lets one person become an admin of a family group, get alerts about fraud calls received by other members, and even end a call on their behalf if they suspect a family member might get scammed.

The company, which has over 450 million users, first launched the feature in December in a handful of countries like Sweden, Chile, Malaysia, and Kenya. Truecaller said that after seeing promising results, it decided to roll it out worldwide, including in India, the company’s biggest market. The feature is free, and users can create groups even if they are not on a paid Truecaller plan.

With this feature, the tech-savvy member of a family or friends group can become the admin of an up to five-member group. Once the other members join the group, the admin can get alerts about potentially fraudulent calls those members receive. If the admin believes that the call could harm the member, they can remotely end the call as well. While the admin can get alerts for fraud calls when a member is using iOS or Android, they can only end calls for members on Android.

On Android, members can also grant permission to the admin to detect real-time activity such as walking or driving, battery level, and phone sound settings (to check if the phone is in silent mode). Truecaller said this is helpful for admins to keep tabs on elderly members and to only call them when they are not walking or driving.

The admin can also block certain numbers and international calling codes, and share a blocklist with group members.

Truecaller noted that the admin can’t see the non-spam call history or SMS history of group members.

“I think, unfortunately, all of us know somebody or another in our families or friends who have been impacted by fraud,” Kunal Dua, VP of Product, at Truecaller, told TechCrunch over a call. “In that sense, it’s a fundamental shift for Truecaller in terms of what we’ve been focusing on as a problem,” he added.

Last year, Truecaller introduced a voicemail feature for Indian users featuring an AI assistant that listens for calls when a user is unavailable and provides a summary of the transcript. The company is exploring a similar AI approach for family protection to potentially alert the admin about what kind of fraud call a group member is receiving.

The company is also exploring using AI to screen calls and automatically disconnect them when certain words associated with scams are detected, such as “digital arrest” — a tactic in which perpetrators impersonate law enforcement officers to extract information or money from call recipients.

In India, scam calls have risen over time and caused financial losses across the country. Truecaller said that it identified over 7.7 billion fraud calls last year. Indian authorities have launched multiple initiatives, including a controversial policy called SIM binding that could hamper the working of apps like WhatsApp and Telegram.

Truecaller is facing headwinds. Its stock has dwindled by over 80% in the last 12 months. During its Q4 2025 report, the company said that its EBDITA– a measure of operating profitability — dipped 49% year-on-year, with ad revenue declining 31%. The company is also facing challenges from India’s Caller Name Presentation (CNAP) system, which displays the name of the caller as registered with their phone carrier. Truecaller has maintained that just displaying a caller’s name won’t reduce spam calls, arguing that its platform goes further by offering community-based reports.

“In India, there has been much talk about the imminent rollout of CNAP,” Truecaller CEO Rishit Jhunjhunwala said during the Q4 2025 earnings call. “CNAP is partially rolled out, and so far, the impact on our user growth is limited. As we have said in the past, we expect that CNAP might have some impact on user growth, but that remains to be seen as CNAP reaches a full rollout.”

Continued Jhunjhunwala, “Our focus continues to be on delivering a superior product, and as you are aware, the consumer can choose to have CNAP and Truecaller in parallel, where we provide a lot more information and a lot more context and various other solutions, for the consumer.”

If you were thinking of seeing Minions & Monstersor at least taking your kid to see it, here’s something to sweeten the pot: George Lucas is in it.

Illumination head Chris Meledandri broke the news in a recent Collider interview, where he revealed the Star Wars creator is secretly a fan of Despicable Me’s chatty champions. “It was such a thrill to learn and share that with the team,” said Meledandri, “He’s among a very small group of people who the entire studio shares a level of respect for that is just off the charts.” Given Lucas’ affection for funny little guys, it makes sense that he loves the biggest little guys of our current movie era.

Now that they knew they had Lucas in their corner, the team decided what the hey, get him to do a voice for the movie. Meledandri said an “idea for a character” was born that fit the bill, and they got “a fast yes” when it was pitched. At time of writing, Illumination’s quiet on who Lucas will be, but it’s worth noting that Minions & Monsters takes place in the 1920s as the crew try to make their own movie. Lucas’ love for older films is apparent in Star Wars and Indiana Jones, so maybe he’ll be a director that ends up getting trampled by the Minions. Maybe he’ll even be one himself who just looks like a little yellow George Lucas, that’d be fun.

Look for Minions & Monsters to hit theaters on July 1.

With electricity costs soaring, home batteries have never looked so attractive. Whether you want to store the excess generated by your solar panels or simply buy electricity at the cheapest possible rate to use later when power is most expensive, a home battery can help. It’s never been easier to get a home battery installed, but this rapidly expanding market can be confusing, and there are several things to consider before you buy.

I’ve spent months researching home batteries, chatting to folks who use them, and then having one installed myself, and I have tips for anyone interested in getting a home battery of their own.

Why Would You Want a Home Battery?

There are several reasons you might want to invest in a home battery, and they are not mutually exclusive:

  • You want to store excess power from your solar panels.
  • You want to live off-grid.
  • You want to guard against power outages.
  • You want to buy electricity at a cheap rate and store it for use later.

Home batteries are a win-win, potentially benefiting power companies too, because battery storage is an essential part of grid balancing and can help manage and make the most of the intermittent power generated by renewables (solar, wind, waves).

How Do Home Batteries Work?

A home battery is like a big power bank for your home. But rather than lithium-ion, they tend to be lithium iron phosphate (LFP or LiFePO4), because it is safer, more durable, and less prone to thermal runaway. In other words, less likely to overheat and burst into flames. There are a few manufacturers working with sodium-ion (Na-ion) batteries, which are potentially cheaper, more environmentally friendly (they don’t require lithium), and perform better in the cold, but they are also larger and don’t last as long.

Home battery technology is often the same as you’ll find in electric vehicles. Some folks have even suggested employing EV batteries as home batteries. But there are potential issues with that, not least finding your car battery drained in the morning. EVs are also driving the technology forward toward solid-state batteries, which are smaller for the same capacity, safer as they don’t have liquid electrolytes inside, and longer lasting.

Many home batteries come in modular systems, so you can add the capacity you want, but they require an inverter to convert the DC (direct current) power stored to AC (alternating current) power you can use. Folks with solar panels, or those who plan to add them in the future, should opt for a hybrid inverter, which can also convert the power from the panels for use or storage.

Inverters have different power ratings in kilowatts (kW) that dictate how much power you can draw at any given moment. Households with modest needs may get by with a 3.6-kW inverter, but that limits your continuous draw to 3.6 kW. They usually have a peak load capability that goes higher, enabling you to pull more for a brief period. If you have high-demand appliances like an EV charger or heat pump, you will want at least 5 kW, and folks with larger demands or larger batteries will want to go higher (6 to 10 kW).

What Should I Look For?

There are several things to watch out for when buying a home battery:

  • Capacity: Measured in kilowatt-hours (kWh), this tells you how much total energy the battery can hold.
  • Power output: Measured in kilowatts (kW), this shows how much energy the battery and inverter can deliver at any moment.
  • Depth of discharge: This is how much of the battery’s capacity you can safely use without damaging it.
  • Efficiency: This is the percentage of the power you put into the battery that you can actually use, because some energy is always lost in the storage process.
  • Warranty: This is a guarantee about the minimum performance you can expect before a battery degrades (they all degrade over time), and it’s often stated in years and charging cycles (whichever comes first). For example, EcoFlow promises at least 70 percent capacity after 15 years or 6,000 charging cycles.

How Much Home Battery Do You Need?

It can be tricky to calculate how much battery capacity you need, and it depends on your use case. If you want to guard against outages or live off-grid, you must consider how much power you use over time and also the sum of your maximum power usage at any given moment to ensure your capacity in kWh and output in kW are enough. If the output is not high enough you may not be able to run power-hungry appliances at the same time, so you’ll have to think about how you use your power.

For folks like me, simply looking to buy at a cheaper rate to use when power is more expensive, any capacity will benefit you. But if you have a cheap six-hour rate overnight, for example, then you ideally want it to last for the other 18 hours. It makes sense to get as much as you can up-front because the installation costs are high. Even adding to modular systems later often requires professional installation to avoid voiding your warranty.

Do You Need Upgrades or Permission?

The home battery will connect to your main electrical panel via a cable, and it may require some upgrades. There was no room on my fuse board when I got a home battery installed, so they had to install a second breaker box.

Some inverters may require permission from your electric distribution utility or local distribution company. Here in Scotland, the distribution network operator must approve your inverter, but you can install and then notify up to 3.6 kW, whereas larger inverters require prior approval.

For folks like me, simply looking to buy at a cheaper rate to use when power is more expensive, any capacity will benefit you. But if you have a cheap six-hour rate overnight, for example, then you ideally want it to last for the other 18 hours. It makes sense to get as much as you can up-front because the installation costs are high. Even adding to modular systems later often requires professional installation to avoid voiding your warranty.

Do You Need Upgrades or Permission?

The home battery will connect to your main electrical panel via a cable, and it may require some upgrades. There was no room on my fuse board when I got a home battery installed, so they had to install a second breaker box.

Some inverters may require permission from your electric distribution utility or local distribution company. Here in Scotland, the distribution network operator must approve your inverter, but you can install and then notify up to 3.6 kW, whereas larger inverters require prior approval.
