Rated 5 out of 5 by from Galaxy M51 This is the best phone I have every had. It runs like a normal samsung and matches my Note 8 for performance. However, the battery life is the main draw here. Its phenomenal. It lasts me 2 full days with everything running at maximum speed and brightness. The storage is huge, 128gb and processing speed is perfect for my everyday use. Gaming its great too, no glitches. If your looking for a phone that does everything plus lasts for more than 24 hours look no further. Well done samsung!

Rated 5 out of 5 by from Want to give it less than 5 stars, but can't! This phone is my first ever Samsung phone which I have been using for over about 6 weeks now and I have so much to say. First things first -- 1) The display on this device is stunning - not just the quality and the size but the ease with which it's viewable outdoor. Even at less than half brightness, the visibility outdoors is quite clear. 2) The battery alone makes it worth the money. While writing this review, I am on the 6th day of usage (124 hours total, 6 hours screen-on time) since previous charge with 24% battery left. Enough said! What also shocked me when I took it out of the box was how light and well balanced it felt. I have tried several big battery phones but they were always too bulky. It can fully charge in a couple of hours but I prefer slow charging. Fast charging can be switched on or off in the settings. Performance is very smooth and easily good enough for web browsing and most of the common apps like FB, WhatsApp, Maps, Zoom etc. I don't play games on the phone so not sure how it holds up on that front. The cameras are also surprisingly good for the job. The main and wide-angle cameras are decent (the main camera is on-par with my previous phone which was supposedly the best two years ago). The macro lens has came in quite handy several times. Selfie camera is certainly very potent. The phone isn't without it's faults. The back is prone to scratches so better get a case or cover right away. Network reception is not as good as my previous phone. The difference seemed much worse at first but then I did some network speed tests and it wasn't behind by too much. Still, I was a bit disappointed at build quality and network reception and was tempted to give it 4 stars. However, the display and battery are just so good that I simply can't. Five stars it is!

Rated 5 out of 5 by from Absolute beast of a battery! I love this phone so far. The photos I’ve taken are good, not amazing, but good (I have a feeling I am the problem though haha) and the battery lasts an age! I stayed up all night and was streaming tv shows and videos for over 8 hours and the battery only went down to 37%! I’m coming from an iPhone so this is an absolute life saver for me. The screen gets bright and dark enough, and has a good resolution, and the software all runs perfectly fine. I’ve tried playing some games and for the most difficult to run mobile games I could run them in the highest graphics settings but it did stutter so I usually opted to medium and then high or highest for easier to run games. I have also tried calling (this was a concern of mine as I had heard you can’t buy this phone in some countries) and it works as you would expect any other phone to work when calling (I’m in the UK). I would highly recommend this phone at this price range for anyone who likes a big phone that lasts a day or even two. My only main problem with this phone is the standard camera application but it’s super easy to use a third party app so it’s not really a problem for me (the photos were always over sharpened and I couldn’t find any settings to change that).

Rated 5 out of 5 by from What a great phone! Amazingly good mid ranger. Lovely screen, great camera, no lag and the battery life is stunning. Ergonomically well designed so doesn't feel as hefty as it should. Very pleased with it.
