Perfine 3800mAh Battery Compatible with Samsung Galaxy S4 Mini i9190 i9195 Extended Battery with 2 Back Cover(Black-White)

My daily routine includes about 1/2 hour of Viber face time first thing in the morning. With the old battery, I'd be down to 55% charge. Using the phone normally for the rest of the day, I'd be at 12% by 3:00 pm. Sometimes, I'd just find the phone completely dead.A friend of mine told me about this battery. I ordered it. Now, after my 1/2 hour Viber face time, I'd be at 96%. It's 10:00 pm right now. I just put it on the charger for the night, with 75% still left on the battery! These results have been typical over the last two weeks of using this battery.Not once have I had to scramble for a charger! Wish I had known about this long ago. It would have saved me lots of frustration.

With this battery, I can run YouTube or Netflix for as long as my last battery (Samsung default) lasted just being on and unused. I haven't had issues with the case fitting improperly either myself from what I've seen of other reviews, I just have nothing bad to say about this battery. Will update in a few months if anything ridiculous happens with it, but for now it's life changing, thanks!

Turned my s4 mini into a usable device. I can now go days without charging, rather than minutes before. Only downside is finding a case to fit.

This battery was a waste of money. It has SLIGHTLY improved the battery life of my phone; maybe by 10%. If the phone lasted 4 hours after a full charge before, it maybe now lasts 6. And that's with NOTHING running; no calls, no internet, no apps. I still find myself charging it constantly all day. I followed the recommendations of letting the battery drain down to empty for the first few charges. That seems to not have been effective. I am either going to have to buy a new phone altogether or suck it up and have a phone with a 3 - 6 hour battery life.

This battery delivers on the 3800mAh...much better battery life than the factory original. However, about once a day it jostles out of place with regularly putting my phone into and out of my pocket. I guess that the sizing is imperfect allowing for some wiggle room? This results in the phone restarting on its own about once a day (and rarely, results in the phone turning off). Annoying but not a dealbreaker for me

I went from less than a day of phone use on a charge, to 3 or 4 days on a charge. That is great. The drawback is that my phone protector no longer fits, but I am hoping that that won't be an issue.

Battery stopped holding a charge after 3 weeks.

Lasts a lot longer than the stock battery.

Update . This battery is no good. I have drained it until power off and charged it full every time and the battery is going down really really fast. I just bought this to replace my really bad 1800 mah battery and this one is Maybe 10 percent better. A regular battery that isn't old would be much better . I do not recommend this product

the package did NOT come with back coversit is a bigger batterie so my actual case does not fit

Very good
