The LG V40 Has the Best Cellular Reception of Any Phone
You need to go to XDA forums and check out what they have to say about reception..There are only two chips there using now in cell phones..Qualcom and Intel..Qualcom is by far the better chip IMHO.although some like Apple are making the Intel chip better than it has been..
Even at that,the pixel 2 and Note 9 still win out and are older phones.
Our tests used a 20MHz channel of Band 4, which is used by AT&T, T-Mobile, Verizon, and the major Canadian wireless carriers, and attenuated an LTE signal from a strong -85dBm until the modems showed no performance.
The tests pitted the iPhone XS Max against last year’s iPhone X with an Intel modem, as well as the Qualcomm-powered Galaxy Note 9 and Google Pixel 2.
In comparison to the iPhone X, the iPhone XS Max offers much faster performance thanks to its antennas, which now support 4×4 MIMO. In PCMag’s testing, the iPhone X averaged right around 200Mbps download speeds, while the iPhone XS Max averaged just under 400Mbps – both under good signal conditions. That’s a dramatic iPhone XS LTE performance bump compared to last year’s model.
As signal conditions worsen, the iPhone XS Max is still able to hold its ground, though it is very, very slightly outdone by the Qualcomm-powered Pixel 2 and Note 9. This, PCMag explains, shows that the iPhone XS Max is very “well tuned” for low-signal situations.
