YISHDA Galaxy Note 4 Battery, 7000mAh Replacement Samsung Galaxy Note 4 Extended Battery with Back Cover & TPU Protective Case for N910 N9100 N910H N910U | Note 4 Battery

Sorry to spoil the party with a bad review but I can only report as I find. Battery life similar to 2 month old non-OEM 3220mAh battery. Stubbornly refuses to calibrate with phone so any additional capacity is wasted as display automatically dims when phone THINKS it's at 5%. I spent 3 hours charging it this evening having completely flattened the battery beforehand. For what it's worth, Accubattery reported just under 5000mAh of capacity. That was 8 this evening. It's now just after midnight and I have 50% charge showing. This is no better than my old battery which is half as heavy half as thick and less than half as expensive. Waste of time like so many of these batteries. I'll keep looking.

My Note 4 was always running down by about 3pm and turning itself off when it still had 35% battery and I was fed up with it. I resorted to carrying a spare battery & desktop charger to get me through but in the end I decided to buy this battery unit.It came with a bigger rear cover & a rubber case.Since buying this is like a totally new lease of life for my phone.I no longer have to worry about how much I use it as it lasts all the way through the day. It does not turn itself unexpectedly. It's like I can trust it again.A great buy.

Smartphones keep getting thinner and thinner... while that's nice to a certain degree, it also has a lot of drawbacks. Making the smartphone considerably thinner while at the same time increasing its power consumption due to the ever-higher screen resolutions is close to impossible given that the batteries are not keeping up. Obviously, something has to give!Battery technology hasn't improved as fast as everyone would like it to. Actually, battery performance tends to "improve" at snail's pace compared to most anything else.After two original Samsung batteries died on me at the most inconvenient moment, I was fuming at Samsung for making phones this thin with such an immature technology. Before switching to another smartphone brand, I decided to give another battery a shot.The YISHDA Galaxy Note 4 Battery with its 7000 mAh turned out to be a great pick. I only wish I had gotten at least two of them right at the start. I like to be able to swap batteries when under heavy use–for instance while traveling–so the phone is always ready to go. Get two of them if you can, and they will last longer.By the way, it comes (also) with a rugged cover and looks like a serious, military-grade device. Awesome!

I bought this produce in September 2020 to replace the original Samsung battery. The company promised significant improvements to battery life. Initially, the new battery did hold the charge longer, but it should have done so given its 7000mAh rating. But, it quickly began to run down, and by April of 2021--so around seven months of average use (I do not stream movies, for example, or play games)--the charge would not last a day of even limited use. Indeed, a full charge would be down to 70% without any use after only a few hours of standby. I would not buy this product again.

Very good and much better than original capacity. If you don't use the extra layer of back protection (which is unnecessary), surprisingly slim, considering. Doesn't come with instructions, so don't know if the battery should be fully discharged a couple of times? Highly recommended.

Took a while to drain and recharge before it reached full charge and now lasts for 2 days in normal use. It has added a bit of weight and bulk to the phone which means you can only use the cover that comes with it.

my bro. got this battery hes happy with it. i got one i happy with its worth the money gone up 3 days before a charge

This battery has brought my galaxy note 4 back to life. I'm so happy with this purchase I can use my phone again without worrying about it running out of juice brilliant.
