Best Removable Battery Phone?

This might be the answer: Samsung Galaxy Xcover FieldPro - Full phone specifications

[li]Released April 2020[/li]
[li]Dual Sim Capable[/li]
[li]4500 mAh Battery[/li]
[li]Latest OS [Android 10.0] with upgrades likely in future[/li]
It doesn't have the best/latest hardware, comparable to the S9, but everything else is very nice B)

Edit: Alternatively with a smaller 4050 mAh battery :

Our phone needs are very basic - for calls & texts only, so:
Aside of the new Moto E6 - which is also very nice, we always use LG models with no real favourites aside of the Volt models which have been very dependable, if smaller than some folks prefer.
We have totally avoided anything that is a throw-away as that seems wasteful to us.

I take it the fieldPRO will be of limited/no use on VZW or Sprint? When VZW shuts off voice on 3g is that the end if CDMA for them? When tmo fully digests sprint will CDMA go away there also?

The one on Amazon (XcoverPRO) says it is compatible with all 4 USA carriers in one of the question/answers.

Interesting. The new 2020 Xcover pro on amazon/samsung looks decent with a retail price of $500. Cameras are supposed to be mid range but I guess you don't buy thing for the best cameras. Flat screen is a plus.

Is this a new phone? New Samsung to me. Built in cover?
