You can reveal the hidden menu by opening the phone call option.

Then enter a series of numbers and symbols into your phone as if you were about to dial a number.

From there, simply dial *3001#12345#* and press the call button.

Click on the call button and a special dashboard with lots of technical information should appear.

But the one you want to look at is called LTE RSRP, which stands for Reference Signal Received Power.

This is basically your iPhone’s true signal strength.

It usually ranges from -140 to -40, and the closer you get to -40 the better.

This area is actually intended for technicians to get detailed information about the connection of your smartphone.

But there’s no harm in staying ahead with this handy trick.

However, you probably won’t understand most of the other features intended for tech-savvy guys.

The so-called Field Test Mode has been lurking for years.

Android Owners can find theirs by going to Settings > About phone > Status > SIM status > Signal strength.

This comes as iPhone users have been urged to review their devices as Apple prepares to delete photos after ending a major feature.

Meanwhile, smartphone owners have been informed about certain settings that can shorten the battery life of their iPhone.

It can be very annoying when your iPhone battery is dead – especially when you are on the go.
