Start by uninstalling and reinstalling just WhatsApp, Chrome, and your main social app, but first use their own in app options to clear downloads and cache, then in Files or My Files sort by size and delete only old screen recordings and large videos you recognize instead of random system folders. This laser focused cleanup often frees several gigabytes of hidden app data and media, which is what ‘Other’ usually is in disguise.

Open Settings > Battery > Battery Health & Charging and turn off Optimized Battery Charging for 24 hours, then in Battery usage tap the top 2 or 3 hungriest apps and disable Background App Refresh only for those specific apps instead of all apps. This targeted reset plus a day of normal use lets iOS finish its reindexing, calms the battery analytics, and usually restores normal battery life without gutting your phone’s features.

Before you reinstall anything, right click the app, go to Properties, then Compatibility and tick ‘Run this program as an administrator’ and set Compatibility mode to an older Windows version, then move the installer or app to a simple folder like C:Apps (no special characters) and run it from there. This single combo often bypasses silent security blocks and weird permission issues that standard fixes completely miss.

Open Activity Monitor and sort by CPU, then close or uninstall any app that regularly sits near the top when you are not actively using it, especially extra browser extensions. For an easy win, create a ‘Focus’ mode for work that automatically closes video apps, pauses cloud backup and limits notifications, which keeps your Mac cooler and cuts down on those loud fan spikes.

Check Battery usage in Settings and uninstall or restrict any app that shows up near the top that you do not truly need, then turn on Adaptive Battery and disable ‘Always on’ screen features. As a quick pro move, set a custom bedtime mode that turns off 5G and background syncing while you sleep, which often adds an extra few hours of real‑world battery life.

Before you ask anything, give ChatGPT a one‑paragraph ‘role and goal’ briefing, like you would to a new assistant, and reuse that same intro for all your questions in that chat. Add one concrete detail from your real life every time, such as your job title, the audience you are writing for or the exact tool you use, which instantly makes its answers far more tailored and less fluffy.
