No current phone from any manufacturer that's reasonably desirable is as small as the 4a, and few of any size have a headphone jack.

Pixel 8a is fairly similar in size. Headphone jacks in phones are (sadly) gone forever i'm afraid.

The 8a is 3mm wider, 8mm taller, and 45g heavier. Perhaps that's not a huge difference, but I already consider the 4a too big. I will likely continue not upgrading as long as LineageOS and the hardware remain usable.

Would grapheneos ( https://grapheneos.org/ ) help with this? I am using a pixel 4a as a "house phone" so it is plugged in all the time but I wonder if I should upgrade.

In the sense that it was a perfectly good phone, and still works with e.g. various bank apps or whatever... and I got tired of jail-break/customization stuff of smart devices about a decade ago... the extra work to wipe everything and explore a new world of things that might turn out to be broken isn't what I'd consider a reasonable option. :/

Most believe that they're trying to prevent safety issues with overheating batteries. This update prevents the battery from being charged too much or too little.

Draining the battery from 100% to 0% in under an hour (as other commenters have mentioned) is the opposite of this, as that will necessarily dump a lot of heat.

No, it's not actually draining the battery faster. It's setting low level limits on maximum and minimum charge levels. (and also the charge rate, further controlling heat issues)

Some folks have hooked up devices between the phone and charge cable that do the coulomb counting (or similar), and (the one case I saw) showed that the phone is only taking in about 40% of the watt-hours that it was doing before the OTA update.

From what I've seen, no one can point to any actual incidents with these phones being dangerously hot. But the google FAQ did have a "Yes you can still take the pixel 4a on flights", reminiscent of the samsung phone issue several years ago...

Could be that the new 100% and 0% are something like the old 80% and 20%

You can revert this if you unlock your bootloader: https://xdaforums.com/t/undo-the-january-2025-update-without... (EDIT: Just to be clear, and which is also mentioned in that post: unlocking the bootloader will reset the device. If your device is already unlocked though, you will be able to keep the data.) Of course, I would just advise to switch to LineageOS directly, since Google has stopped providing security upd…

How is the photo quality? I love the pictures from the old 12MP sensor + Googles software, but I understand this is not in Lineage?

Well, they are good enough for me, but to be honest, I'm not particularly picky... As said in a parallel post, you can get GCam in APK form (I run LineageOS without GApps) but I hear it's a bit trial&error to find one that works and I haven't bothered.

My spouse had to buy a new phone because of this issue. Neither of us got any notification about the battery issue. Even if we did, what Google is offering here isn't great. We tried to get the battery replaced, but was told that the process could likely break the screen and jack up the cost to nearly the original purchase price. Sending the phone in for repair also isn't a good solution because she needs it for auth at work. What a mess.

FWIW I was on Pixel 3a until last month; bought Pixel 6 in the meantime, but it was too big and heavy to carry around, so I only used it as a "tablet", only at home.

Just updated to Pixel 8 and it fits the hand very well (including Spigen Liquid Air cover), and doesn't feel too heavy. Have a few friends who got Pixel 8 last month on sale as well and they all confirm.

> Since this is a major release, the Pixel 4a (5G) and Pixel 5 have not been ported to Android 14 QPR2 as part our initial release. We need to determine whether it makes sense to move these end-of-life devices to Android 14 QPR2 or keep them on a legacy extended support release branch based on the last Android 14 QPR1 release.
