PowerBear 2X Phone Battery Replacement for Note 4 [3,220 mAh] with Note 4 Spare Battery Charger Cradle | Note 4 Battery | Note 4 Spare Battery & Note 4 Replacement Battery Kit [24 Month Warranty]

The thing about it that I don't like is the fact it takes almost 4 hours regardless if the batteries are at 72% or 19%. I just got done watching it today. Set up my webcam to take a picture every 5 seconds, and it took it 3 hours, 40 minutes to charge.Put it on the charger at 1:30PM, 01-16-2017, done charging according to the 5s interval time lapse video, 5:10PM.But it was at 72%, so it shouldn't take that long. My opinion.I used VideoVelocity Free version with my Logitech C920 Webcam.Charging : Purple/Pinkish light.Done or no battery : BlueThe port is for charging your phone, not to charge the battery inside the charger. Which is kinda dumb.Had this product for almost three weeks, and they seem to be working just as good as the orginal OEM battery, before the battery would shut the phone off at 40%. Also, another reason why I got it, instead of fixing the charging module inside the phone, is because the charging module is also damaged. I've tried very hard over the years to take good care of my Note 4, because it's my first premium smartphone. So I guess, even with someone such as myself, the hardware will old and wear out eventually.I would like to fix the charging module, and I know of the site and everything where to find the module for the phone, so maybe I'll do that too, so this way I can charge my phone the way I was doing before.I rated it four stars, because I'm not in love with the batteries. That's why. I simply just like it.I haven't had any problems with the batteries, other than the fact that the charger takes 4+ hours to charge, no matter how dead the batteries are. I guess they did it that way to be safe.I also understand how Lithium batteries are charged, god knows there's videos on YouTube that teach that.If it were a constant current, then it's something like 3220mAh / 4.083 hours = 788.63 mABut as you probably already know, that's not accurate. So expect to wait 4 hours for your battery to charge.

I'll get right to it: Skip to the last update!Original review: These Power Bear batteries are as good, if not better than the OEM Samsung batteries. The charger is a slow charge 600mAh input, which is far less than the Note 4's OEM included 2.1 Ah AC charger adapter. My observation, after a few weeks use, is that the slow charge might be better in that it doesn't build heat while charging, which is beneficial, as high temps are bad for lithium polymer batteries.Just for note and comparison: I bought my prior Note 3 new (T-Mobile) and utilized a special offer that allowed me to buy 2 additional OEM batteries for it, thinking I could swap out batteries on the fly, as needed.The Note 3's included battery had a noticeably longer life than the 2 supplemental batteries bought online from the official Samsung website. What I recall is that the included battery showed assembled in China, manufactured in Japan. The 2 bought online showed manufactured and assembled in China. My point? Even Korean branded smart phones are using components manufactured in China. And just because you buy OEM, you aren't necessarily getting the best technology available. Aftermarket components aren't necessarily poorer than OEM in quality or performance, as might have been the case in the past.Chinese components, batteries, etc have the potential to be good quality, if you're willing to search for it and pay for it. These Power Bear batteries seem to be a good example. Better still, the price is competitive, and shipping with Prime membership is quick.Seems to be a win-win proposition!Update 10/17/16:Definitely better battery life than original while in use, but the biggest difference is during standby. With my phone use habits really no different than before purchasing, I notice that standby remaining battery life has increased nearly double. Therefore, the need to plug in at the end of the work day isn't as necessary as before. Very pleased with this battery company!Update 1/23/17:Sorry to say, but my initial reviews were a bit too premature after 4 months. The batteries charge quickly with the fast-charge option on my Note 4, but they also drain quickly. As I mentioned earlier, while on standby, the batteries maintain charge decently, but while in normal use, they lose energy fast. Add video play or gaming and they are downright disappointing. I had high hopes, but I'm afraid the only real advantage to this brand is the price and the fact they don't ignite. Your mileage may vary. Godspeed.

Pros: great battery life, not stuck by an outlet, seem to run cooler than the original battery.Cons: no instructions for the charger, couldn't find a website for the company to explain the different lights shown so I don't actually know how long it takes to charge.My original battery was starting to show 2% when it would shut off but 11% when I would start charging. Bought these two as back ups and will start using them as my primaries. After one day of use I can tell a significant difference in battery life. I use my Note 4 as a work phone with heavy usage and my original battery wouldn't last 4 hours into my work day before needing charged. Now I can almost go all shift before replacing the battery instead of being tied to a wall. The second battery gets me through the rest of the shift and the rest of the day using my original battery as the spare which I didn't need.I have seen red, blue, and purple leds on the charger. There was no instructions shipped to explain what they mean. When not plugged in the wall with a battery in, the led comes on, worried that may be wasted electricity when charging. This is the only reason it gets 4 not 5 stars in my book.Haven't tried the usb port to charge the phone while charging the battery.
