[NFC/Google Wallet Capable] Anker 6440mAh Extended Battery for Samsung Galaxy Note 4, N910, N910U 4G LTE, N910V(Verizon), N910T(T-Mobile), N910A(AT&T), N910P(Sprint), with Black Back Cover

I have always bought from Anker and I hate to say it this is the one time that it was not a good purchase and that is because I bought it twice to see maybe at the first time was dud. I do not get much better screen time or standby time than the stock battery.UPDATE: 10/04/15I was contacted by Anker, about my issue with the battery that I gave a review on earlier, and they sent me a review unit to see if maybe the ones I have previously purchased were duds. at first I was shocked that they would want to send me a review unit since not a well-known reviewer.But after going through 6 charge cycles with this new battery I can honestly say that Anker is back up in my top companies. the battery does give me double the standby time that I would normally get from a stock battery, and also I do actually gets doubled the on screen time use as well. I would like to thank Anker, for their great customer service and for caring about our reviews. still one of the best companies out there to buy batteries, bluetooth speakers or cables for all my devices.Will continue to go to this company for all my purchasing needs.

First, I was not given this battery to review, I actually bought it. I checked other extended batteries but I did not want to spend that much (Hyperion & Zerolemon) so I decided to try it out, glad I did! Battery came with 50% juice. I didnt try to calibrate or anything the first time around, I just wanted to waste the battery. I got to 1% and it lasted 1 hour 20 minutes at 1% until it died. I went ahead and charged it and it took about 5 1/2 hours to fully charge. At 5 hours it was at 100% but said still charging with the red light. Waited 1/2 hour more and it finally said "Charged" and the green light went on. I calibrated the battery once it was full and was ready to test it.I use my phone, and when I say use, I mean use. I did put the brightness alittle above 50% (since i usually have it at 30%) and was able to get 1 day and 22 hours of use. Wifi, GPS, Sync 3 emails, tons of texts, music and videos, and games. I listened to almost 12 hours of music on Google Play, 5 hours of music of my own, and 9 1/2 hours of screen time. That to me is alot and that is under heavy use.I would not hesitate to recommend this battery, great company and great use. The back cover is nice and has great grip, not like others. I would get a cover (Hyperions $9.99 cover) to add some protection. I have the Note 4 for T-Mobile and the case fit perfectly. You do have to snap it hard. Overall, I am greatly impressed by this battery. Buy without hesitation.

This is a great Battery Expansion.As noted by other it does make your phone almost twice as thick and twice as heavy.They provide a different back cover to allow for the twice as thick battery.Pros:At least doubles the battery life. You can game for hours!GREAT Customer service!Cons:With the weight of the battery and the way the back case has curved slick edges it no longer fits in most Car Dash mount holders.As others have mentioned it is a very slick case and does slide off things easily. I can't knock the product for this but it is a bummer.Even if you can fit it in the car holder (the one i used is the popular Iottie 2), with the added weight if you hit a bump in the road it will pop it out of the holder.The case fits super tight. I actually had trouble with the original one they sent. Customer service was fantastic and they sent me a new one.I live in Michigan and its super cold when i tried to put the new case on. I had trouble with it clicking into place again, but once i let the case warm up inside and with the battery warming up I was able to push it again and it snapped in place perfectly. Its been 3-4 months and it has never popped off again.So to sum it up. perfect product for the price, but to get the extra battery you will sacrifice a few things. It also makes it hit the ground a LOT harder with the added weight so I have a few dings on the side of the phone. Good luck finding a protective case that fits...I don't knot if its the weight or the slick back cover but I had hardly EVER dropped my cell phone in the past.. but I seem to drop this on a weekly basis.. But again I can't knock the product quality for that but wanted to give people the heads up.

Summary: Great product while operating normally, however the battery is causing issues after 7 months.Pro: Fantastic battery lifeCon: Lasted 7 months, backshell has little to no grip ao be prepared to drop your phones a few times.**EDIT**Got in touch with Anker about their 18 month warranty. They sent a replacement after I provided them with my order # and battery serial #. The battery is preforming well and my phone is no longer randomly rebooting/freezing. It is worth noting that my OEM battery was messed up at the time too.

I rate anker high among second rate batteries for my note 4.My batteries had a recall and the market is flooded with second rate batteries.

Perfect fit, but one of the corners cracked. Perhaps the plastic is slightly on the brittle side. Overall satisfied.

WORKED FOR ME

Battery lasted 17 months with daily usage

First perfectly. Unbelievable battery life on one charge. No noticeable overhearing, Fit's perfectly with the custom back plate and is still an absolutely reasonable size for a...

The battery worked great for about 3 months. Battery charge would last all day. But now this battery has been gradually getting worse with holding a charge.

excellent

Excellent Battery I use in my Note 4. The battery literally lasts all day with heavy usage. No problem with charging or loss of charge in the months I have owned it.

I bought one of these in May 2016, and I was very happy with the extra battery life. Sometime in 2017 I noticed my screen was 'bent' slightly, but I thought maybe I had just...

Had to return it. It didn't quite fit properly.
