A wave of new handsets arrived in September with unusually large batteries, including models pushing past 10,000 milliamp-hours, roughly double a typical flagship, in pursuit of multi-day life rather than the thinnest possible body. Battery capacity, measured in milliamp-hours, is the single biggest factor in how long a phone lasts between charges.
The trend reflects a segment of buyers who value endurance and durability over slimness and premium materials.
What it means: for staff who work in the field, on deliveries, at events, on site, a rugged phone with a very large battery can be more useful than an expensive flagship. Matching the device to the job, rather than defaulting to the priciest model, often saves money and headaches.
