It’s difficult to state why Google is doing this rather of a recall.
Exactly what is incorrect with the batteries in a few of Google’s Pixel 4a phones still out there? Google has not truly stated. Now that lots of Pixel 4a owners are experiencing significantly decreased battery life after an unusual upgrade for an end-of-life phone, they are dealing with an unusual range of alternatives without any course back to the phone they had.
Google’s “Pixel 4a Battery Performance Program,” revealed in early January, informed owners that an automated upgrade would, for some “Impacted Devices,” lower their battery’s runtime and charging efficiency. “Impacted” consumers might select, within one year’s time, in between 3 “appeasement” alternatives: sending out in the phone for a battery replacement, getting $50 or the comparable in their place, or getting $100 in credit in the Google Store towards a brand-new Pixel phone. No security or risk concern was discussed in the assistance file.
Ars has actually connected to Google about the Pixel 4a battery updates and appeasement alternatives offered and will upgrade this post with any reaction.
The curious kernel
Google did not describe why just specific gadgets were impacted, however Hector Martin– of Asahi Linux, open source Kinect chauffeurs, and other popularity– took apart the upgrade’s binary kernel and has some guesses.
Martin mentions that the upgraded Pixel 4a kernel has these fascinating attributes:
- It appears to have actually been constructed by a Google engineer “on their personal machine, not the proper buildsystem.”
- There is no source supplied, as would typically be needed of a Linux kernel construct, though it might just require to be supplied on demand under the GNU General Public License.
- The optimum charge voltage of specific battery profiles modifications from 4.44 volts to 3.95, which would suggest batteries can not credit anywhere near their previous capacity.
- There are 2 primary battery profiles, with unique “ATL” and “LSN” markers; Martin recommends they associate with Amperex Technology Limited and Lishen, makers of battery cells.
- LSN-tagged batteries appointed the “debug” profile can see capability lowered from 3,080 milliamp hours (mAh) to 1,539 mAh.
2 hours on a charge or less

One Ars staffer who had a Pixel 4a still in usage got the upgrade. They saw their battery life drop from “Still working” to “Two hours on a charge,” in their evaluation. They had actually selected the Google Store credit choice before the upgrade gotten here and before the battery life drop emerged. As soon as picked, a various appeasement alternative might not be chosen.
Others have actually kept in mind all however unusable battery life on their phones, as seen on subreddit threads and blog site summaries.
Even technically smart Pixel owners will have a difficult time preventing the upgrade. Google recently got rid of all of the Pixel 4a’s factory images from its site, avoiding owners from rolling back their firmware without needing to go searching for an image (or transform to a third-party offering, like LineageOS). Without any source and debug code published for the modified kernel, third-party firmware companies can not quickly integrate the battery repairs.
Some Pixel 4a owners have actually reported that, even after a battery swap, their gadgets have the exact same restricted battery capability. This would verify Martin’s tip of a malfunctioning battery cell type which batteries with those exact same cells are still being utilized in replacements. (Martin’s post offers identification numbers one can search for on the battery part to show the cell producer.)
$30 each year to get $50
As seen on a wiki page on the Pixel 4a battery program hosted by repair work supporter and YouTube developer Louis Rossman, and kept in mind by Pixel 4a owners on Reddit (and the Ars staffer), the $50 credit provided by Google is paid through supplier Payoneer.
Registering to be paid through Payoneer needs supplying a Social Security number or other recognition, birth date, and examining account information to a monetary services company most non-business owners would not acknowledge. Payoneer keeps in mind on its website that it charges a $30 yearly account cost for accounts that get less than $2,000 in 12 months. It is apparently left as much as Pixel 4a owners to liquidate their Payoneer accounts after getting their credits.
Selecting the $100 Google Store credit may appear the much better alternative, however there is a caution there, too. The discount rate uses just to Pixel phones and just to gadgets that are not otherwise on sale.

The huge concern: Why?
As we kept in mind when Google initially revealed the upgrade, a great deal of Pixel 4a batteries are now 4 to 5 years of ages. Some have actually been kept as secondary(or “junk drawer”phones, and numerous are currently at decreased capability, specifically when at low charge levels and in cold conditions. If every Pixel phone this old got a battery-minded last upgrade, meant to avoid unexpected shutdowns (similar to Apple’s initially unannounced iPhone slow-down repairs), there would not be rather the quantity of protest and confusion there is now.
Google has actually not stated why particular Pixel 4a phones are “Impacted Devices” and others are not. It has actually not clarified what problem is so noteworthy or extreme regarding press an automated upgrade to a phone from 2020, such that its battery life is all however annihilated. No news or neighborhood reports have actually appeared yet of Pixel 4a gadgets triggering fires, and even merely stopping working to operate, after 4 years. It’s an automated upgrade with a strong repair, however for what?
Google’s assistance page just mentions that the upgrade will “improve the stability of their battery’s performance.” This holds true in the sense that, if you stop utilizing a seriously capped Pixel 4a completely, its battery can offer a steady quantity of output (none) into the future.
Google assistance personnel have actually recommended to more than one 4a owner that yet another future upgrade might require a factory reset and automated upgrade. That hasn’t happen, a minimum of in the timelines recommended by assistance personnel. All of this raises the concern as to how this complicated procedure is much better than a standard recall, if there truly is some kind of threat, to gadget or human, with a specific set of batteries.
