Bypass charging is a feature that allows a smartphone to draw power directly from an external source—like a wall charger—once the battery reaches a certain charge level, typically 80%. Rather than replenishing the battery, the device draws energy directly from the charger, essentially allowing it to run without relying on the battery.
“With bypass charging, Pixel devices can run directly off the charger once the battery hits the 80% threshold, reducing battery strain and heat. This essentially allows the device to operate directly from external power, much like a laptop does when it’s connected to a charger, leaving the battery out of the equation."
This approach is a significant shift from traditional charging, where the phone continually cycles between charging and discharging the battery, even when plugged in.
Preserving battery longevity is the main reason for implementing bypass charging. Lithium-ion batteries degrade faster when they’re charged to full capacity and subjected to frequent charge cycles. Over time, this leads to reduced battery life and diminished device performance.
By capping the charge at 80% and switching to bypass mode, Google aims to:
Prolong battery lifespan: Fewer charge cycles and less time at high charge levels reduce wear and tear.
Improve thermal management: Devices generate less heat when not actively charging the battery, which is especially beneficial during gaming or demanding tasks.
Optimize power delivery: The device receives only the power it needs for current tasks, improving efficiency.
This feature reflects a broader industry trend toward sustainability and longer device lifespans, aligning with user demands and environmental considerations.
With the December 2024 update to Android 15 QPR1, Pixel phones now offer two related features:
Battery Charge Limit: Users can set their phone to stop charging at 80%.
Bypass Charging: Once the battery hits 80% and remains plugged in, the phone draws power directly from the charger instead of the battery.
How to Enable Bypass Charging:
You can verify bypass charging is active by checking your battery status—it should show “not charging” and the power source as “AC”.
The introduction of bypass charging is part of a larger movement in the future of smartphone longevity in 2025:
Device Longevity: Manufacturers are focusing on features that extend the usable life of smartphones, reducing electronic waste and supporting sustainability goals.
Battery Health Awareness: Users are becoming more conscious of battery degradation and seeking ways to preserve capacity.
Software-Driven Hardware Optimization: Updates like Google’s December Pixel Drop show how software can unlock new hardware capabilities, even on existing devices.
