Which app fits your battery question?

TurtleBar answers a daily planning question: how much working time is left, and should Low Power Mode turn on now? It can show remaining time or the clock time at which the battery is expected to empty, then apply rules based on battery level or the app you are using.

coconutBattery answers a diagnostic question: how does the battery's current capacity compare with its design capacity, how old is it, and how has it changed? The vendor also documents iPhone and iPad checks, saved history, and more detailed analysis in its paid editions.

iStat Menus is the broader option. Battery and power sit alongside CPU, GPU, memory, disk, network, sensors, and weather, so it fits people who want one configurable system monitor rather than a battery-focused workflow.
