So far the Ulefone Power was great. Its battery is indeed superb. When heavily used I get at least 2 day out of it and with normal use 3-4. Sometime even more. The display is good. Viewing angle good. Sound when calling good. Looks a but bulky but you need to put the battery somewhere isnt it? It's GPS is excellent. 1-3 meters accuracy is very good. This was a pleasant surprise for me. The camera works very good in bright conditions. Darker situations is less but still pretty good Charging is very fast. from almost empty to 100% takes indeed 2 hours as advertised. But you have to use the sapecial adapter that Ulefone provides. Also a silicone case was in the box. And 1 screen protector. I do not use that as the Gorilla class is great. You can use 2nd SIM card but only when you dont use the slot for a SD card. The battery is build in and not replacable. Adding all things up makes me say that it is a very good phone for its budget price. I did pay 145 euro for it when I used a special internet offer. Normally you can get them for 165-170 euro.
