For me here are my Top List using my iPhone 14 Pro Max
1. Heavy Gaming - Such as Genshin Impact, PUBG, Call Of Duty, Mobile/League of Legends 5v5.. Other PPSSPP Games or PS3/PS4 emulator, .tends to drain the most of all time. All Performance, Efficiency Core, Video card, and Ram will work 70-100% on this device makes device melt.. my iPhone 14 only last 4 hours playing nonstop either of this games especially Genshin…
2. Moderate Gaming - Such as Roblox, Asphalt Nine, Clash of Clans.. however this makes my iPhone last 7 hours
3. Light Gaming - Such as Candy Crush, Fruit Ninja, Puzzle games and Etc..
4. Editing - Videos or GarageBand, 4K editing or something like that… a good 9 hours from my phone.
5. Web Browsing - Just like gaming it uses ram and cores To load images, ads and informations or data’s.. i think I have spent 12 hours from just browsing from 100 - 1% after it shut down.
6. YouTube/Netflix/Video watching - Doesn’t really drain battery for me.. especially when you’re only watching 720p or below. I watch a series from Netflix nonstop and Its 13 hours overall.
7. Microsoft Word/Excel - involves lot of typing but doesn’t really affect battery as it’s mostly text.. no animations or whatsoever.
8. Reading iBook or Manga - Just like YouTube it’s already there so the ram and cores don’t have to work that much..
