Criticisms of 5G technology center on health concerns (potential effects of radiofrequency radiation, despite lack of strong evidence), cybersecurity vulnerabilities (new attack surfaces from increased connectivity and software reliance), infrastructure challenges (need for dense cell networks, higher energy use), and privacy issues, along with conspiracy theories linking it to unrelated events like the pandemic, though these lack scientific backing.
While 5G's algorithms are even more comprehensive than its predecessors, users are still vulnerable to cyberattacks. One area of concern is encryption. While apps on 5G networks are encrypted, the 5G NR standard doesn't have end-to-end encryption, leaving it open to certain kinds of attacks.
5G wireless radiation linked to altered brain waves during sleep. A recent study published in NeuroImage found that individuals with specific gene variants who are exposed to 5G frequencies experienced changes in their brain wave activity — measured via an EEG — during sleep.
The prevalence of the highest power levels (superior tail emissions) appeared much more frequent for 5G-FR1 emissions than for 4G, and a difference of as much as 9.5 dB over mean power was encountered in 5G versus 4G emissions.
Turning off 5G really extends your battery life.
Switching 5G off saves battery because, when connected to a 5G signal, your cell phone is basically connecting to a bunch of different, smaller networks all at once. This rapid loss of charge may also cause your phone to heat up.
Definitely! As 5G is a big improvement from 4G in terms of latency rate and speed, it offers a far better gaming experience. If you're a gamer, 5G will enable you to play online games without a hitch - on both mobile and gaming devices as well as laptops through a hotspot.
Navigate to Connections. Select Mobile networks. Tap Network mode. Choose 5G preferred or LTE preferred.
4G is not being phased out in the U.S. anytime soon, but it's anticipated to phase out starting in 2030. Mobile carriers like Verizon, AT&T and T-Mobile, have committed to maintaining their 4G networks for years to come, even as they expand their 5G infrastructure.
They are safe because they are non-ionizing and they are low-power. Power levels for wireless communications are tightly regulated by the Federal Communications Commission (FCC).
With network switching, poor signal strength, and data-hungry apps, 5G devices can drain batteries faster than 4G models. However, by adjusting network settings, switching to Wi-Fi when possible, and using battery-saving modes, you can significantly extend your phone's battery life.
What happens if we keep our phone near our head while sleeping? It will lead to poor sleep quality, increased anxiety, cognitive decline, and potential long-term health risks due to radiation exposure.
10 Harmful Effects of Mobile Phones
Can 3 days without a phone really make a difference? Yes, research shows measurable brain changes after 72 hours. Stress and anxiety decrease, sleep improves, focus sharpens, and social connections strengthen.
'Not worth it'
It found that while phones often display the 5G logo, the data being transmitted is still carried by older 4G infrastructure. The difference isn't always obvious to users, but it can mean slower downloads and buffering in places where they expect the ultra-fast network.
Reduced Radiation Exposure : Unfortunately, 5G technology emits higher frequency radio waves compared to 4G. By disabling 5G, you can reduce your exposure to these higher frequency EMFs, which some individuals believe could be beneficial for health.
6G Speed and Performance
While the exact specifications are still being defined, experts predict that 6G networks could deliver speeds up to 1 Tbps – that's 50 times faster than 5G. This incredible speed will enable new use cases and applications that we can barely imagine today.
5G uses a 256-bit encryption algorithm, while WiFi uses WPA2 with AES encryption and WPA3 uses 192-bit encryption. The 256-bit encryption provides more robust encryption because it increases the number of possible keys, making it harder for hackers to brute force the correct key.
The biggest difference between 4G and 5G is the speed. 5G has the potential to be up to 10 times faster, because the way 5G works means that it uses smaller wavelengths and much higher frequencies which can support far more simultaneous connections than 4G.
Additionally, the ICNIRP increased the reference levels for the general public averaged over 6 min for RF frequencies >2–6 GHz (those that will be used for 5G in this frequency range), from 10 W/m2 (Tables 5 and 7 in ref. no. 6) to 40 W/m2 (Table 6 in ref.
(But if you were to build a brand new network today, you would likely use 5G only.) They won't even starting thinking about 4G obsolescence until 6G is established, in the early 2030s.
A modern 4G phone in 2025 can still provide an excellent mobile experience for most daily tasks. You can expect: Reliable internet browsing and social media use. Smooth video streaming in HD.

In most cases, you will not need to change your SIM card to use 5G. Most 4G SIM cards are backward compatible with 5G networks. The reason is that 5G networks often require a specific type of SIM card called a 5G SIM or Universal Integrated Circuit Card (UICC).
Will a 5G device work with my current sim? Yes, your 5G device will be able to use a 4G sim to receive 4G/3G/2G coverage whenever it needs to.
What happens if I move from a 5G coverage area to a 4G coverage area? With Jio, you will be able to move seamlessly between 5G and 4G networks without any action or intervention required on your part. The network display on your mobile will show 5G or 4G depending on the coverage available in your location.
