I was at a phone store yesterday considering a new phone. I don't have need or use for a high end one. Was looking at two models. The cheaper was 4G LTE, the other was 5G. The store person said something about the end of 4G LTE but didn't have any dates. I usually keep phones for several years until the battery goes bad or I need more memory for ever expanding apps. Do I need to consider life of 4G LTE phone or is it going to be long enough I don't need to think about that yet?
