5 hour battery life is not that impresive especialky for lightweight apps such as whatsapp, tiktok, youtube, etc. Playing games like roblox can get warm really easily

    2 years with this device and still running like a new phone! But the ghost display has been showed.

                So first impressions, love the phone design, small and compact. Battery is good enough to get you through the day. Phone gets really hot to the touch when performing somewhat demanding tasks. Gaming performance is nice.

                  Got 1.1 GB update with August security patch

                        Heard a couple of comments on samsung forum that s21 has started experiencing this also. Anyone can deny or confirm this ?

                                      My S21 screen just died, always black except sometimes completely green...As the golden edge of the frame had a lot of scratches in my purple version, i got rid of it. But it was a very good phone, great size and good cameras. So i just bought a 8/256 GB S21 FE, and it is even better than S21 for half the price. Very easy to save and restore your data with Samsung cloud.

                                        Bought a year ago, No green line issue here but a white ring around the front camera cutout like a burn (not much visible at all so no problem to me). Super fast charging is now little bit slow cuz oneui 5 update slowed down the charging speed (0% to 85% about 55minutes. before 46min). And the camera, there's some blurred areas in photos which is really annoying to me when taking close pictures of documents. I didn't noticed that before so, cannot confirm that it is a hardware thing or a software issue. One problem about the frame, is rusting or something like that. Everything else about performance is perfect as new. I don't play games at all but I tried genshin impact once, and never again. Because I believe that the extreme heat when playing caused that burn around the camera cutout. Ah not only around camera, around the whole screen too.

                                        Model: SM-G991W (Snapdragon varient)
