Battery Life: A drivers perspective

Race weekends don’t really leave room for anything to go wrong — especially not something as simple as your phone dying. When your entire day depends on staying connected, navigating, tracking performance, and capturing moments, battery life stops being a spec and becomes a necessity.

That’s where the difference shows.

The HONOR X9d is the kind of phone you carry without thinking twice. It just works — all day. No stress, no constant battery checks, no scrambling for a charger between sessions. It keeps up with the pace of a race day the way you need it to.

Then there’s the Ulefone Armor 24 — less of an everyday phone, more of a powerhouse tool. It’s built for endurance in the purest sense. The kind of device you rely on when you need something to last the entire weekend without even thinking about plugging it in.

Two very different approaches, but both solving the same problem: staying powered when it actually matters.



Battery Life: A drivers perspective

Race weekends don't really have an off switch. I'm up early, usually before most people are awake, and I'm not getting back until late — sometimes after packing down the kart in the dark. There's travelling, prep work, long hours at the circuit, and somewhere in between all of that, the small things start slipping through the cracks.

My phone's battery was one of those things for a long time. Between GPS to navigate between tracks, checking live timing, staying in contact with my team, and trying to capture content throughout the day, my phone is working almost as hard as I am. It's become a genuine tool, not just something sitting in my pocket.

And when it dies halfway through the day — or I've left my power bank cable somewhere — it's not just an inconvenience. It actually affects how the day runs. That's when I started taking battery life a lot more seriously than I used to.

What Makes a Phone’s Battery Good?

Honestly, I never used to think much about battery specs until race days started teaching me the hard way. What I've learned is it really comes down to three things.

Capacity first — the mAh number. The bigger it is, the longer it lasts. Phones sitting around 4500–5000mAh handle a heavy day reasonably well, but on a long race weekend with live timing, GPS, and video running constantly, you start to feel the limits.

Then there's how efficiently the phone actually uses that battery. I've had phones with decent capacity that still died fast because they ran hot and burned through power doing basic things. A phone that manages its power well just lasts longer in practice, not just on paper.

Fast charging is the one I underestimated the most. Even a great battery runs low eventually, and being able to get back to 50% in around 20–30 minutes — one session on track — is the difference between stressing about it and forgetting about it entirely.

Those three things alone make a solid race day phone. But then there are some phones that take it to a completely different level.

The Phones I’d trust on race day

By mid-morning on a race day, my phone is already dying — hot, slow, and begging for a charger I've probably left in the hotel room. It's a familiar headache.

The HONOR X9d just fixed it.

I went through a full race day — travel, live timing, video, constant messages — and didn't think about battery once. It stayed cool, stayed fast, and was still going when I got back at night. No battery saver mode, no closing apps, no asking around the paddock for a cable. I just used my phone normally, all day.

The 8300 mAh battery is the obvious reason, but what I didn't expect was how much it changed the day. And when I do need to top up, about half an hour gets it back to 50% — roughly one session on track. Enough time to charge without it disrupting the rest of my day.

It's one of those things that sounds boring until you've spent a race day without it.

This one's different. The 22,000 mAh battery sounds absurd on paper, and honestly it kind of is — I got through an entire race weekend on one charge. Practice, qualifying, races, live timing, recording, messaging. Never plugged it in.

But I'll be straight: it's a brick. Nobody's slipping this into their jeans pocket. That's not a dealbreaker, it's just context.

Where it actually makes sense is as a pit lane utility phone. Leave it running live timing all day, hand it to the mechanic to even charge HIS phone, mount it as a dedicated GPS between tracks. It just sits there and works without anyone worrying about it dying.

It won't replace the phone in your pocket. But as a tool that stays on all weekend without fuss, nothing I've used comes close.
