Works well; No Instructions
We got this for our son's older model galaxy (S9+) until we figured out if we were replacing the phone altogether. I have to say, I was pleasantly surprised. My son said by 3pm, his phone was at 10% if he was lucky. Now after replacing the battery, by the end of his school day he's at 38-40%. The only complaint I have is that there were no instructions. My husband is techy enough that he could figure it out, but if you're not techy, please find someone who is. Would recommend.

Battery is horrible.
Battery is horrible. I received this yesterday and it was at 40% charge. It took 24 hours to charge to 100%!! used phone for 10 mins and it dropped 69%!!! Second night THE BATTERY IS DRAINING WHILE IT IS BEING CHARGED!!! It only charged to 91% and I woke up to find it charging at 81% !!! Battery is a POS! I wrote the seller yesterday and so far no answer! I can't return it without not having a phone!! This is the second battery that I purchased on Amazon this week the first was DOA seller refunded immediately! Five minutes after I contacted him!

Works, no increased battery life
Replaced my batteries in 2 of my Nintendo 3DS XL. Battery fits fine and works, but even after multiple cycles (letting it die completely and recharging) I still only get 3-4 hours from a full charge. That’s arguably worse than the OEM battery with far less mAH. The description advertises a much longer life than OEM. It works but don’t expect a longer battery life
