iPhone 8 Plus Battery Health Concern

yeah, its 3 weeks old today and its already down to 98%, this is my replacement iPhone. i feel my old phone i sent off for repair that the battery on that was so much better and performed better than what the battery does on this replacement phone.

i’ve heard that the ipad plugs 10W can damage your battery too? is that possible?

i saw a video on youtube and this man had a 6 plus for 2 years and his battery health was 86% and he has had the iPhone X for a year and that was only on 96%. he was saying this the benefits of wireless charging

Thanks, but 3 weeks come on. My partner uses her phone everyday and we both facetime all the time and use our phones a lot but shes had hers for many months and her battery is still at maximum 100% where as mine is at 98%

i heard wireless chargers are good for iphones? i heard they do like trickle charge so when they get to 100% they keep it in low power to keep it at 100%?

what you think
