for Pixel 4a 4G Battery Replacement Kits Compatible with Google Pixel 4a 5.81'' Model G025J, GA02099 with Adhesive and Repair Tool Kits

When I got a new Pixel 9, I gave my 12 year old son my Pixel 5. But within a few months it had split open with a really puffy battery. The Viimon Battery Replacement Kit for Pixel 5 was only $21.98, so I figured I had nothing to lose.In my case, the puffy battery had already broken the seal on one whole half of the phone. That made it very easy to remove the screen, which I understand can be one of the hardest parts of working on one of these sealed phones. So I can't comment on that, because in a sense I was lucky.The kit comes with instructions (including photos), and every possible tool you would need: mini screwdriver, tweezers, plastic pry, etc. as well as parts like a new edge seal. You have to remove some tape, disconnect a few things, remove about ten tiny screws, and then pry the old battery away from its adhesive. The whole process took maybe 15 minutes. The only part that was even a little challenging was reapplying a new sheet of edge adhesive, which is really narrow, and with the small area and stickiness, is like a Lego sticker set from hell. But again, no big deal.The result was a phone that was nice and flat. I put it back on the charger, and within minutes was able to boot it back up, no problem, no issues, just like nothing had happened. Compared to spending hundreds on a new phone, it seems like an extremely good value.The only real question is how long the battery will last. We will follow instructions and do a full charge/discharge/recharge cycle 3-5 times and see how it does. My hope is that it at least lasts half as long as the original, which survived for 4.5 years before failing.If you have any technical skills, and have enough manual dexterity to handle tiny screws, you should be able to do this. I wore two sets of reading glasses so I could see what I was doing. My son held a flashlight at times. I will provide an update later if anything changes, but right now I can say that I would definitely buy this kit again.

So far so good, kit came with all parts needed for a battery replacement for Pixel 4a. I will update if the battery fails at some point. I should note I did not use the included instructions and instead used a video on youtube for a step by step guide and I recommend you do the same. The video by iDoctor UK was very helpful and he even helps remind you what screws go where.The replacement process itself is rather difficult and I wouldn't recommend for anyone who hasn't done a battery replacement before or isn't familiar with electronics. You have to be very delicate removing the screen.

Unfortunately they are selling Pixel 4a 4g batteries with sku or serial number 8230020501 manufactured by Lishen. Google released an update that significantly hinders the battery performance on units with the serial number. It's a shame too because this seller is one of the few that includes the adhesive to reseal the lcd screen.

For those who wrote they had an easy time on this and did in half an hour, good on you. I'm pretty good on DIY projects around the house and I'm used to doing work on my desktop PC such as installing GPUs, RAM expansions, removing a CPU fan for a deep clean, and installing a new SSD drive, etc. This battery change was not easy. I prepped by reading the instructions and finding a YouTube vid (not the exact same kit as Viimon but very similar) and watching it. Working in such a small space is very exacting--lot's of opportunities to damage wiring and circuits if any tools slip etc. Getting the case separated wasn't too hard, getting as much of the extra sealant off as possibly was time-consuming. I don't think you really need to get every bit of glue off, I still had some areas with light coverage, but I did get most of it. The 10 screws you have to remove are tiny--you need good hands and good vision and patience. Getting the battery out was very hard--took a lot of slow, meticulous prying. The "gasket" of new adhesive was tricky to work with without deforming it but I managed to do most of it ok. Put the gasket on before you rewire the two halves of the phone together but you have to be cautious so the un-gasketed part doesn't stick to the gasket as you try to snap the wire connectors together in the tiny space you have. Probably a few breaks in the gasket aren't going to be an issue. After 2+ hours I did get it done, and...holding breath...powered up the phone, and...it worked. Was concerned something got loose/damaged during all the work.Make sure you have plenty of light, a good clean worksurface, and somewhere to keep track of all those tiny screws. Tools I added to what came with it that came in handy: a very small flathead screwdriver (mostly for prying out the batter), a utility knife with a sharp blade and exacto knife (for work separating the two halves of the phone), a flashlight (for a little more light on the phone at times and for finding that one screw that fell on the carpet).Final takeaway...If you're not handy to a reasonable degree or don't mind if you destroy your phone trying to change the battery and gain some skills, then just buy a new phone.Will update this commentary if problems with the battery show up.Updating my review on 1/21/25: a week or so ago the phone started running out of charge very fast--assume it's the battery--so my wife's Pixel 5 got a few more months of life and I leveled up and attained the "change battery in a sealed phone" skill. So was it worth it? Not really...so next up will be a new phone.
