ITMBET Battery for Samsung Galaxy S21 Ultra, [6000mAh] Upgraded 2024 New 0 Cycle EB-BG998ABY Battery Replacement for Samsung Galaxy S21 Ultra 5G SM-G998B/DS SM-G998U with Replacement Tool Kits

I used the battery and set it up, initially thinking it was defective. It eventually turned on after multiple tries to unplug and replug the mini cables.

This item certainly is a battery. If yours is taking a dump, this'll absolutely brighten your day. If your battery is just getting weak and you're looking to give it that extra oomph, this isn't it.

I bought to try to upgrade my old battery since my phone is 4 years old and guess what? The new one is discharging almost the same as my older one. Not satisfied at all.

Finally installed this after return deadline but who wants to return a battery after you put it in? Easy to put in but no instructions and no battery adhesive. You have to email them if you want instructions.Description says 6000mAh but phone shows it's only 5000mAh. Do not buy this product or you end up with same problem. My first review was not put up because I called it out as it is. But you get the point. Don't buy this battery or you get same issue. What it says is not what you get.Every app says it's 5000mAh. Company should send me the right battery.

Being advertised as a 6000 mAh I would say this China manufacturing company embellisehed a bit. It's works but it's all day life span doesn't compare to the original.

No issue found with this battery
