    The battery is great! The phone is a bit bulky though especially with a case. The camera is stellar. Not sure it's worth the large price tag but it is a great phone and I expect to have it for a few years.

    Extremely expensive but you get what you pay for. Its a solid flagship that can contest the latest iphone in terms of camera quality (sllightly worse than apple) and performance (better than apple)

    Amazing phone. The camera detail, the performance, light weight, perfect size. Never had a slow down, never crashed, battery still lasts for almost a day and a half when in somewhat moderate use. Perfect amount of memory for everything I have.

    Does everything it needs to do as a phone. Cameras are becoming pretty standard across all higher end smart phones, so not much to say there. Battery will last me 24 hours or more in a place with horrible reception, which was far better than expected. Screen is huge, only downside is accidental touches on the side of the screen, due to the curved edges, while watching something or trying to navigate a website. Other than that would recommend.

    So if you're buying this to see the moon. Don't. When did you care about looking up at the moon normally anyways? Regardless if you are stuck between this and iphone 13 pro max. I went for this and i also own Iphone 13 pro max and let me say battery life screen brightness display just looks amazing on this compared to iphone. Though iphone does have a little more natural shadow coverage and makes the picture look warm this has a brighter screen and much higher brightness compared to the Iphone. I all depends on you. You want something that works for a long time or you want to buy the name. Chances are you want to buy the name and go for iphone. Either way great phones you won't be dissapointed

    When a phone costs over a thousand bucks you'd think they'd supply the power cord. I was a bit disappointed that all you get is a cable... and it's not the typical usb... it's the 3.0 to 3.0...i don't have a block that receives that size. Thankfully, older chargers from my s9 work on this one as well. The camera is great. The phone doesn't hold as great of a charge as I had hoped with a new phone though. Also, it went from 7% to 1% to shut off within a minute... that's usually 3 year old phone status. I also had issues with my mobile data connecting...I had to turn on airplane mode and then turn it off to get data signal back. (Had to Google the issue once I was back on wifi and after getting lost...I rely on Google maps too much!)

    Nice size and great battery life. I miss the ox cord output so you can charge your phone while playing music with a system that doesn't allow bluetooth. I love the camera, videos and pictures are awesome.
