So i have since a few months a new phone the honor magic 5 pro and have some things i am looking for and hope you guys might be able to help me solve the problems i have i will list them from most likely you can solve them to least likely.

1. i have loads of saved wifi passwords/names on my old huawei p20 pro that i want to migrate to my new phone how do i do that (i currently don’t have root on both phone’s but am willing to get it if it doesn’t void my warranty on the new phone and doesn’t require me to do a new system install/wipe my phone and doesn’t cost a crap ton of money (time is no issue))(edit i dont have acces to the wifi networks so qrcode sharing wont really work)
2. how do i optimize my battery usage regarding refresh rate and resolution? put it on low or smart? (both 60hz and low res is more than enough for me) also i have a app (track work time) that checks my location often can i maybe limit its frequency in settings?
3. how do i teach the power management system to without me disabling it (putting it off auto) in the settings not kill my mail apps and some other apps?
4. where is my wifi scanning frequency toggle in developers settings on my old phone it only ran a wifi scan every 30 seconds or so but in dev settings there was a disable rate limit switch.
5. do you know somewhere in the Netherlands that has public wifi 7 so i can test if it works on my phone?
6. how do i map my volume up and down buttons in the camera to something like manual focus or zoom?
7. in my camera app where is my megapixel setting or is there non and just high res or normal?
8. can i in software (again i dont have root see question 1) control my charging speed to limit it to something like 500ma instead of the max a charger can supply?
9. is there a way to get an lower brightness than the minimum on the slider? or will my display look just always display white at max brightness(or what feels like it when its dark around me)?
10. is there a way to get my 960fps 720p slowmo back from my 5 year old huawei p20 pro on my honor magic 5 pro?

Thanks for your help solving this issues for me or letting me know if it can not be done.
