How Brick Maximizes Battery Health and Sustainable Powerbank Management
We monitor battery health through usage patterns and charge cycles. Since phones handle their own heat protection, we skip extra sensors in the powerbanks, keeping our system simpler, more reliable, and built for long-term performance.
As a global leader in shared powerbanks, we take battery health seriously because it affects everything: reliability, sustainability, and long-term cost.
This guide explains how Brick protects battery life across thousands of devices, based on proven best practices and real-time data.
What causes lithium battery degradation?
Brick has data and analyses from hundreds of thousands of powerbank cycles. The main drivers of wear are:
- Charging to 100%
- Discharging to 0%
- Fast charging too frequently
- Charging while the battery is hot
These factors accelerate chemical breakdown inside the battery and shorten its usable life.
What does Brick do differently when charging?
We’ve optimized our charging profiles to reduce stress on batteries.
Here’s what our stations do:
- Avoid full charges: we cap the charge at ~85%
- Prevent deep discharge: we retrieve and recharge before 0%
- Slow down if hot: temperature sensors regulate charge speed
- Skip fast charging unless needed: gentle charging is the default
This dramatically extends battery lifespan — and it's built into every Brick station.
How does Brick track battery health?
We don’t guess. We measure.
Every Brick powerbank is monitored in real-time. We primarily track:
- Charging cycles
- Usage patterns in the field
We focus on usage patterns and charge cycles because they provide enough data to accurately assess battery health. Since modern smartphones already include built-in thermal protection, there’s no need for additional heat regulation during charging on our side. By avoiding extra sensors inside the powerbanks, we reduce complexity and improve reliability, leading to a more robust and integrity-focused system.
We also utilize machine learning models trained on historical data to estimate State of Health (SOH). All local partners are notified of any indications of worn-out batteries
What happens when a battery starts to degrade?
Brick has a structured battery lifecycle plan:
- ✅ If usable, the battery is reassigned to a low-demand location
- 🧰 If near end-of-life, components may be refurbished, or possibly only used in controlled environments, such as small-scale events
- ♻️ If no longer viable, the battery is responsibly recycled
This ensures we get maximum value out of every battery and generate minimal waste.
Why is Brick focused on this?
Because battery health is the backbone of a sustainable network.
- Fewer replacements = lower environmental impact
- Longer battery life = better ROI for partners
- Proactive maintenance = fewer service interruptions and increased safety
- Smarter charging = better experience for end users
We don’t just rent powerbanks. We manage a high-performance, high-efficiency infrastructure, and battery intelligence is central to that.
What’s next?
We’re rolling out new capabilities in 2025:
- Real-time health insights for partners
- Predictive maintenance alerts
- Even more efficient charge algorithms
Brick is setting the standard for battery-first, planet-friendly powerbank sharing.
Do you have, a question about how we handle charging, sustainability, or hardware quality?
Ask us. We’ve built our expertise at scale, and we’re happy to share it. We're also looking for more partners to expand our network.
