“apple pencil battery life”

I bought my iPhone 12 in March 2021. I use both 5g and wifi for over 2 months. After I updated to IOS 14.5, I noticed that my battery health went from 100% to 95% in just 2-3 months. After that, I stopped using 5g and just used wifi. But it is still draining fast. I only use my phone for social media and use it for gaming sometimes. I also use Apple’s 20watt charger. I also don’t let my battery life go down to 25%. Now, my battery health is at 92% in just 5 months of using it. What exactly is the problem and how can I prevent my battery health from draining too fast? Is my battery defective?

After multiple Restore and Factory Restores and a session online with Apple Support that resulted in put an Apple-branded battery in it, I have come to the conclusion that the 11.3 beta for iPhone 6 is incompatible with non-Apple-branded batteries.The result: my iPhone 6 is now worthless until I can get an Apple-branded battery installed. Right now there's a 5-week queue in the Portland area for an iP6 battery.My battery life was poor (6 hours) so I knew it was time for new battery. Running 11.2.5 at the time, Apple announces battery replacement program. Immediately Apple batteries are at a premium and I can't get one. So I ordered an iFixit battery and installed. New battery, new lease on battery life. Wonderful.Then I install 11.3 and suddenly the phone is shutting down with 30-70% charge remaining indicated. When I plug into external source, phone restarts

I just got a new iPad Pro 10.5 and I've immediately installed iOS 11 on it. Now I'm trying to find a good note taking app but OneNote doesn't seem to recognize my Pencil. Google tells me this should not be the case so I guess this is iOS 11 related. Does anyone else have this issue?

I sure wish Apple would allow the Apple Pencil to be used to simulate 3D Touch on iPad Pros. Anyone else interested in this? Thanks!
