Teh Pixel 4a’s Battery Woes: A Deeper Dive into the “Update of Death”
The Google Pixel 4a, once lauded for its affordability and solid performance, has recently become the subject of much frustration due to a software update that has substantially reduced battery life.This ”update of death,” as it’s been dubbed online,has left many users scrambling for answers and solutions.
Hector Martin, a security researcher and developer known for his work on the Asahi Linux project, has shed light on the issue, calling it “a real hack job.” His examination reveals that the update intentionally lowers the maximum voltage the Pixel 4a’s battery can reach, effectively shrinking its capacity and leading to significantly reduced battery life.
Understanding the Voltage Issue
Martin explains that lithium polymer batteries, like those found in the Pixel 4a, typically have a maximum voltage they can safely handle. Manufacturers usually allow them to charge to this maximum for optimal performance. The Pixel 4a previously allowed its battery to charge up to 4.44 volts, but the recent update has capped it at 3.95 volts. This seemingly small difference translates to a noticeable decrease in battery life.
Martin states, “3.87V nominal lithium polymer batteries have a max voltage of 4.45V or thereabouts,so the original setting was not wrong. but now they’re suddenly being very conservative.” This suggests Google’s decision to lower the voltage is intentional, raising questions about the reasoning behind it.
The Battery manufacturer Factor
Martin’s investigation also uncovered that the Pixel 4a uses diffrent battery models from ATL and LSN manufacturers. Interestingly, the update appears to only affect phones with LSN batteries. He advises users to check their battery model by looking for a number next to the QR code on the back of their device. 8230015901 indicates an ATL battery, considered “good,” while 8230020501 signifies an LSN battery, the one experiencing the battery drain issue.
Potential Reasons for the Update
While Google hasn’t officially explained the update’s purpose, several theories have emerged:
Battery Life Extension: Google might be trying to extend the lifespan of the LSN batteries by reducing the voltage, potentially mitigating risks associated with overcharging.
Thermal Management: Lowering the voltage could help manage heat generation, improving the phone’s thermal performance. Software Optimization: The update might be part of a broader software optimization effort, with unintended consequences for battery life.
Impact on Users
The update has left many Pixel 4a users frustrated, with some reporting a drastic reduction in battery life, making it difficult to use the phone throughout the day. This has sparked online discussions and calls for Google to address the issue.
What Can Users Do
Check Battery Model: Identify your battery type to see if it’s affected.
Contact Google: Reach out to Google support for potential solutions or updates.
Explore Battery Replacement: If your battery is LSN, consider a replacement with an ATL battery.
Looking Ahead
The Pixel 4a’s battery issue highlights the complexities of software updates and their potential impact. It underscores the need for openness from manufacturers about the reasons behind such changes and the potential consequences. It also emphasizes the importance of user feedback and its role in shaping future updates.
pixel 4a Battery Drain: An expert Weighs in
The Google Pixel 4a, once praised for its affordability and performance, has become embroiled in controversy thanks to a recent software update causing important battery drain. Hector Martin,a security researcher known for his work on Asahi Linux,sheds light on this ”update of death” and its implications.
Time.news: hector, thanks for taking the time to speak with us. Many Pixel 4a users are experiencing drastically reduced battery life after a recent update. Can you explain what’s happening?
Hector Martin: Sure. Essentially, this update intentionally lowers the maximum voltage the Pixel 4a’s battery can reach. Lithium polymer batteries,like those in the Pixel 4a,have a maximum voltage they can safely handle.Previously, the Pixel 4a allowed its battery to charge up to 4.44 volts, but this update caps it at 3.95 volts.
Time.news: That seems like a significant drop. What’s the impact of this voltage reduction?
Hector Martin: It translates to a noticeable decrease in battery life. 3.87V nominal lithium polymer batteries typically have a maximum voltage of 4.45V. The original setting wasn’t wrong, but now Google is being extremely conservative.
Time.news: Are all Pixel 4a models affected?
Hector Martin: Interestingly, it appears to only affect phones with LSN batteries. Users can check their battery model by looking for a number next to the QR code on the back of their device. 8230015901 indicates an ATL battery, considered “good,” while 8230020501 signifies an LSN battery, the one experiencing the battery drain issue.
Time.news: Why do you think Google implemented this change?
Hector Martin: Google hasn’t officially explained the update’s purpose, but there are a few theories. perhaps they’re trying to extend the lifespan of the LSN batteries by reducing the voltage, mitigating risks associated with overcharging. Another possibility is thermal management – lowering the voltage could help manage heat generation. It’s also possible this is part of a broader software optimization effort with unintended consequences.
Time.news: What advice would you give to Pixel 4a users experiencing battery drain?
Hector Martin: First,check your battery model. If you have an LSN battery, consider contacting Google support for potential solutions or updates. Another option is exploring battery replacement with an ATL battery.
Time.news: this situation highlights the complexities of software updates. What’s your broader takeaway?
Hector Martin: Transparency from manufacturers about the reasons behind updates and potential consequences is crucial. User feedback plays a vital role in shaping future updates, ensuring they benefit everyone.
