I've had a chance to try out the new Jio Phone models, and they've made some interesting updates. In terms of battery life, they generally perform well for a budget phone, often lasting a full day on moderate use. App compatibility is improving with each update, but if you're used to a broader selection of apps like on Android or iOS, you might find it limited. Usability-wise, they're quite straightforward, which is great for those who prefer simplicity over lots of features. If basic functionality and affordability are your priorities, it's a solid option.
