What happened was:

1. Battery defects caused some of them to underperform, leading the battery management subsystem to shut down the phone due to voltage drop when too much current was drawn.

2. To work around the shutdown issue (very bad), Apple implemented throttling (IMHO less bad) in a new version of iOS, to prevent too much current from being drawn. They figured the throttling would be so light as to be unnoticeable to users, except...

3. Benchmarkers noticed the throttling, and all hell broke loose.

Battery defects are unfortunate, but the decision to make them not user-serviceable leads to a host of bad downstream decisions.

(Of course, making them user-serviceable also leads to a host of other difficult decisions, and I'm not just talking about opening the case. What happens to system design when you can no longer trust the battery's specs?)

Annoying 150 USD store credit can't go towards something like Youtube Premium. Or multiple 6a credits can't be stacked on 1 device. Cause I'm never touching a pixel again.

This seems very fair

I didn't get from the article how the update will make the phone unsable.

My personal policy for buying anything with such a battery: the seller must have a meaningful presence in my country and sell for at least like $10M/year.

In January 2025, Google pushed an emergency Android update to Pixel 4 devices which completely killed the battery's life.

They offered an extended warranty to get the battery replaced at any official Google repair center for free. They claimed a new battery would resolve the issue and your battery would drain at a normal rate.

For context I live in NY and the official Google repair center I visited has ~500 4.7 star reviews. I'm not going to out them publicly because despite all of this nonsense the local store owner seemed genuine.

VISIT 1: I went to their official repair center and they swapped the battery. It took ~2 hours plus ~45 minututes in travel time.

The new battery was put in and it did help but it still drained faster than pre-any updates. However it was usable from a battery life perspective.

After the repair I noticed my phone's display stopped turning on when I picked up and angled the phone towards me. I also noticed that more often than not if I got any type of notification (even an incoming call) the display would not turn on. Lastly, my phone would not unlock normally. Normally I would flick the bottom of the screen with my thumb maybe 1 inch and it would turn on and prompt me for my pin. Now I had to drag my entire finger up the whole phone like I'm 80 years old and it would only unlock 30% of the time.

---

VISIT 2: I explained the situation to them, another ~3 hours of total time at the store.

They replaced the display of the phone and it made little difference. There were still problems listed above which I demonstrated in front of the store owner.

He went back and got some tools and they hooked up a diagnostics tool to my device in front of me and confirmed the proximity sensor was not functioning. The owner of the store told me it's unfortunately common for this to get damaged during a battery replacement.

He said the best they can do is order a new motherboard but it will wipe everything.

At this point I've already had a ~30 reply email thread with Google support where they kept saying they can't do anything except suggest keep going to the repair center I've been to.

VISIT 3: They replace the motherboard, another ~3 hours of total time at the store plus ~3 hours to set everything back up again on my own

Most of the issues went away, but the phone still doesn't turn on a lot when I get new notifications of any kind.

However, the battery started draining quite fast again. We're talking losing 28% battery for a 2 hour phone / voice call with the display turned off.

Just texting my friend on Whatsapp with 15 messages drained 5% battery. My phone at this point is very not usable with battery life. The battery life is ok if it's idling doing literally nothing but as soon as I do anything, it drains fast.

There's ~50 replies to the Google support email and they said sorry, nothing they can do. I can mail the phone to them and they can try repairing it but it will cost me out of pocket and I'll be out of a phone for however long that process takes.

VISIT 4: The repair center gave me a new battery

At this point I told them I can't afford to keep going to the store and having my phone damaged on every visit and they said they can do the battery replacement at my apartment in their work truck. The store owner told me "changing the battery is the easiest thing in the world, it's safe to do in the truck".

So their most experienced tech came and did the battery replacement.

The tech told me the phone is good to go, quickly showed me the phone's display is turned on and I unlocked it with my pin like I normally do. He left.

The store owner told me this is the last time they will service the phone and if there's any other problems to call corporate.

Over the rest of that day and early morning next day I noticed the battery replacement made zero difference, it still drains at the same rate. My phone is essentially unusable and not dependable from a battery life perspective.

However, I tried logging into my trading platform of choice which is 100% dependant on biometric 2FA and if the fingerprint fails it falls back to the pin.

That app won't even let me attempt to login, it simply errors out saying biometrics is unavailable. My bank's app says the same thing. The phone itself has zero reaction to the fingerprint sensor. It's completely dead.

I called them and let them know and he said sorry, it's really easy for the fingerprint sensor to be damaged during a battery replacement.

He said he can order a new sensor and service it one last time but it might be a day or 2. I told him I'm locked out of my trading account with my life's savings actively in the market and if I can't execute a trade due to this, should I hold him or the corporate company responsible for any losses.

He very quickly said to hang tight and 5 hours later he sent someone to do the repair because they found a different fingerprint sensor at a different store location (they have a few locations in a 30 mile radius).

VISIT 5: They come with a new fingerprint sensor

They used the truck again with the same senior tech who swapped the battery in visit 1 and visit 4.

I ask the tech to do an exhaustive test in front of me at the end to ensure everything is in working order.

The tech says he can't do any tests and told me basic things like turn the phone on, take a picture, etc.. It was up to me to walk him through my definition of an exhaustive check based on limited knowledge so I did everything I could think of and it all worked, except charging was very spotty which turned out to be due to his charging cable being bad, it worked fine with mine.

The fingerprint sensor worked when I tried it a few times on that visit.

However, after using the phone for a few days I noticed something really weird. The fingerprint sensor is literally moving behind the back piece of the phone. In fact, if I took my fingernail I could probably pick it up and lift it out. It does not feel normal.

---

I called corporate and explained all of this. Someone was supposed to call me back yesterday but they never did. Now it's near end of day on Friday so I doubt I'll get a call back until next week.

This whole ordeal has been like ~80 Google emails of which for the last 3 weeks, Google stopped responding to them. All of my responses are objective, asking for assistance, non-confrontational, non-emotional and completely reasonable. I just want a resolution where I have a working phone that I can depend on without me needing to buy a new one because a 2 trillion dollar company forcefully broke my phone.

This whole experience has jaded me in ways I never thought was possible from witnessing a massive amount of incomptenance and complete lack of care towards someone who has been using Google products since Google was invented.
