alogim, Jan 6, 2018 : Well, just to be clear, every manufacturer suggests wiping the cache after installing an update, but almost noone does this. Frankly speaking, everything works exceptionally smoothly for me, even without wiping it. I had an LG Optimus 4X HD before, and I can tell you it was a real nightmare for the common user but a very nice phone for one interested in testing ROMs. Concerning OnePlus, I do not know enough about the past models, but bot for performance and battery life, no phone is on pair to this one, except perhaps the Pixels, with pure stock Android. I have a friend with the Samsung Galaxy S8, and after a couple weeks it starts lagging, with that micro delay in apps that is really frustrating, thanks to their heavy proprietary UI. The same was true for my former LG, Optimus UI was very heavy, going from an app bqck to the home required waiting for a couple seconds in order for the home screen to load, even if there was nothing to actually load (i.e., no shortcuts). Battery life on this phone is outstanding, I managed to get more than 10 hours SOT with a single charge with an usage that is really heavy in my opinion. I bought this phone also for the excellent community support. I think developers will compile ROMs for this device for the next five years or so, and I hope to become one of them, even if my knowledge is more computer-oriented.
