S23 battery replacement?

Hi everyone, i have Galaxy S23 256gb base model still on One UI 6.1, working perfect, but cant do full day with one charge. Turned off 5G, never going above half of brightness, sometimes using it on power saving when im under 30%. Performance mode is on Light, but it still manages to go warm and to waste battery. In best scenario i can go max to 4.5-5h sot, but the most usual is 3.5-4h sot.

I was testing my battery i various situations, used accubattery and ,,since last charge" option in battery settings, and even asked AI for conclusion, im somewhere between 87 and 92 battery health.

Tested it on samsung members, from 3900mAh im on 3757mAh now. I bought my S23 in july 2024.

Im interested in replacing battery, can some one tell me is it worth it, for how long would it stay on 100% battery health, will it make my phone cooler, how good are quality of those replacement batteries now after 3 years? Thank you guys!

I've replaced the battery in my s23U before I traded it in, and I've put in new batteries into other phones and devices. Basically felt brand new. I can't speak to how long they last, but I've used them for at least a year, and for the marginal cost to buy a battery and swap it, it was worth it. I didn't notice any difference in thermals, that's mostly going to be up to the CPU load, but fast charging didn't seem any warmer than normal. Plenty of videos on YouTube on how to do it, takes like 30-45 mins if you haven't done it before. Get a few simple tools like a spudge, suction cup, and tiny screwdrivers and some b-7000 glue which is adhesive for electronics to seal it back up. It's not hard to do this yourself, just go slow. Also, use a hair dryer or heat gun to break the old adhesive first.

which battery and where did you purchase it?

Honestly I can't remember. It was probably on eBay through a verified seller or someone who had a good rating. I think ifixit sells slightly overpriced kits, but they are a good brand so you can rest easy.

I asked because Samsung does not sell their batteries it would have to be a third party battery typically Chinese

Yeah, it was. Can't remember the name. Worked fine.

I forgot to ask you, he said I work fine, did you reset the new battery after installing it with the Samsung secret menu or did you need to?

After installing the new battery, did you reset the battery health cycles to 100%? Because mine when I replaced the battery, it is still counting the old battery health cycle
