Hi Product Hunt,
Working remotely and often on the go, I kept running into the same problem: I’d join a meeting, start talking, and only then notice my Mac was at 2%. Afterward, the awkward scramble for a charger and an apology to everyone on the call. It never felt very professional, but plenty of people related, and some even had to do the same a few minutes later.
I wasn’t ready to replace an otherwise good Mac just to get a fresh battery, so I started looking for a better solution. Honestly, nothing existed, or it was subscription locked. So I started building it. That became Battery Sensei.
The idea was simple: tell me about my battery when it actually matters. Reading my calendar and understanding its current state, consider the meetings ahead and warn me in style.
What started as something for friends and colleagues grew from there. Battery Sensei now shows power use per app, measures your actual charging speed to help spot slow cables, can protect battery health by limiting charging or pausing when the battery gets too hot, and gives you insight into apps battery usage. Having custom alerts at the percentage you want and so much more.
However, the core goal is still the same: stay zen, stay in the background, and speak up only if your battery becomes a problem.
I’d love to hear what you think.
The Meeting Guard feature is genuinely smart, caught my low charge before a long call this morning. Love that it stays out of the way otherwise.
The Meeting Guard idea alone makes this worth it, but I would love a quick summary notification that pops up saying exactly how many minutes of battery I have left before that next meeting starts. A simple visual bar or percentage right in the alert would help me decide whether to grab the charger or just bring it along.
The Meeting Guard feature alone is worth it — finally caught my dying Mac right before a client call. Love that it just stays out of the way the rest of the time.
Meeting Guard is honestly the killer feature here, finally something that warns me before my mac dies mid-zoom. Also love that it just chills in the menu bar without bugging me all the time.
