Ulefone Power 5, 5 years old.
I bought this Ulefone Power 5 in 2019, now in its 5th year the battery 13,000 mAh isn't as strong as it used to be. I bought a Fossibot rugged tablet as my phone still works fine as a phone, the Fossibot battery 22,000 mAh doesn't last any longer, so that's going back. I should have bought the Ulefone tablet and will as soon as I get a refund. Ulefone has kept me going for five years and thankfully is still working. I just wish they'd continued the Power series as I have no requirement for ruggedness. Unfortunately, all manufacturers are now obsessed with ruggedness as if they expect we all live in tents year round.
