I have no experience of Android Go, Michael, but while scanning through the latest copy of PCPro magazine on Readly today I noticed a recommendation in an "Xmas gift ideas" feature mention of the Nokia G10 running the Android One version. The comments included "despite its low price (quoted at £110 from Argos) it has a large pleasant screen, a solid array of cameras and enough speed to keep Android 11 happy : it comes with the streamlined Android One version of the OS, and will include regular monthly security updates for 3 years" . They also mention 48 hour battery life.
I have been using a Windows Phone version Nokia (530 IIRC) for the last couple of years & it has been OK. Certainly OK for the price, as I was given it by a friend who didn't like the Windows Phone experience. I didn't have it on a data service contract (PAYG) so just used it as a phone and camera (probably more camera than phone ! ). I could easily get 3 days between charges on this, with it Bluetoothed to the car while travelling to & from work (about 2 1/2 hours a day).
But Virgin have just dropped the PAYG service I have used for years and, having moved to a Lebara "rolling monthly plan", I wanted to be able to use the 3 Gb monthly data allowance. The Windows phone was clunky & slow for the "on line" functions & my previous Android phone was too old to run the current versions of "Apps", so I have been largely forced to upgrade. Mrs B has been happy with the Xiaomi Redmi Note 9S I bought for her last year after a lot of reserach into getting the most Bang for Buck – big clear screen, fast, decent camera, big battery & decent reviews – so I have ended up with a Xiaomi Poco X3 Pro. Bought direct from Xiaomi UK online for £199 delivered next day, it is a marked upgrade from anything else I have had previously. The "list" price of the X3 Pro was £249, but I happened to be looking on the day they had a Flash Sale with £40 off + there is a £10 discount with a code for items over £100 + free shipping. This phone is "only" 4G, but there doesn't appaer to be much 5G about at present & Mrs B has been getting pretty snappy results from her 4G phone so happy not to pay more for a 5G phone at the moment.
HTH & good luck in your search – you can drive yourself crazy trying to make the "right" decison !
