## Description

High Capacity Replacement Battery

Review: works, lasts 6 hr slightly better than origional - The only problem with this battery is that it doesn't meet my expectations for capacity. I initially thought it would have double the mAh of the original Samsung Galaxy battery, but it turned out to be less. After a few uses, the original battery in my phone, which I've used for over six years, has degraded from lasting about six hours to around three or four hours. I hoped the new 10,000 mAh battery would last approximately eight hours based on simple calculations, but that’s not the case. Charging the battery to around 85% provides the best protection, but even when fully charged to 100%, it only lasts about six to seven hours instead of the expected twelve hours. This shorter lifespan is disappointing, but understandable given that it’s a cheaper battery. The charging speed is satisfactory. However, it's important to avoid letting the battery drain to zero or overcharging it, as these practices can cause micro-damages that reduce the battery's duration, lifespan, and capacity.
Review: UPDATE: SWELLING AFTER 3 MONTHS - Tight Fit, but works good. - UPDATE 06-07-26 SWELLING AFTER ONLY 3 MONTHS. SO MUCH SWELLING THAT THE SCREEN KEEPS POPPING OUT. DO NOT RECOMMEND. DOWNGRADED TO 1 STAR Good replacement battery for the money. Fit was quite tight. Just barely fit in the space for it. It also seemed a slightly thicker than the factory battery. At first I was concerned that it might keep the screen from fitting all the way down, but it ended up working just fine. I broke the screen when trying to get it off (my fault - no fault of this battery manufacturer) Ordered a replacement screen, and put it all back together. So far, it's charging fine, and seems to last a while. Worth noting: The cable that connects to the main board was just slightly too long, so I had to adjust where the flex cable bent. But worked out fine. Overall, would buy again. Note: I also got this same battery in a different variant for my daughter's iPhone 14. That one was great. Would give it 5 stars. It won't let me do a separate review for that one.
