[3950mAh] Galaxy S9 Plus Battery Li-ion Replacement Battery for Samsung Galaxy S9 Plus SM-G965 EB-BG965ABA G965U G965F G965W Spare Battery with Repair Tool Kit

My phone was dying after about 4 -5 hours and now after replacing it lasts almost all day. I dont know if it lasts as long as brand new phone but it works for me.

I was expecting this to be better since it has a larger capacity. I replaced my now over 4 year old phone battery and this new battery doesnt last as long as the old one. I've been using it for a few weeks now and it looks like I'll have to find another battery.

Great value for the money but the battery shows its age after a couple months of use unfortunately

Ya fue instalada y si cambia la duración le.daremos.mucho a ver que tal será la calidad es perfecta su calidad

Thia new battery needs charging almost as frequently as my old one did.

I'm very suspect. To me, it looks like they took a regular, run of the mill, ~3500mah replacement S9+ battery, and covered it in a green sleeve that has the 3950mah claim. If you look closely, none of the input/output voltages are on the green "sleeve", which is mostly my source of skepticism, as batteries almost universally have voltage/current draw and inputs printed on the battery casing.Not to mention, it hasn't given really any better performance than the relatively new ifixit replacement i bought. Again, it's fine. Accubattery gives me about a ~2600mah estimated actual capacity (which is about on par or worse than my other 3500mah batteries). Im almost positive its still probably better than a 4 year old stock battery, but don't expect any miracles

good

If you don't know how to open the back to replace the battery...then you're just wasting money. You have to heat the adhesive..again no instructions telling you anything...to open the back to replace the battery. This seller thinks everyone knows that
