HELIOTION Galaxy Note 4 Battery, Upgrade 4200mAh High Capacity 0 Cycle EB-BN910BBE for Note 4 SM-N910 N910H N910F

My original battery started to expand. Bought this battery and so far it works as expected. Holds a charge and provides good battery life.

I'm not sure about two things:1) The only way to be sure about long term longevity is to use for a long time. Over the past week I've charged a few cycles and let run on battery for extended periods of time - please read below.2) I'm not sure about the mha rating - the industry in general seems to "fib" about these numbers.What I _do_ know about this is:You have to disregard the first charging cycle - my battery came with about 30% or so charge when installed into my Note 4 and it seemed to charge (again the first time) very quickly on a non fast charge charger after letting it go to 100% for about 10 minutes (green light on the phone lit) I unplugged the device and let the experiment begin. After about 2.5-3 hours it was in the low teens (around 13%) and I thought "well that's not good..." and begun to think I'd be scammed and I'd be writing a negative review and see if it would be worth it to return the battery or just chalk it up and go on. So after the battery went in to the single digits I charged it again (this time it went much slower) and after about 1/2 an hour after full charge I checked the level of charge every few hours and with no power saving settings on it lasted about 12 hours. I repeated with another full charge and with power saving settings enabled got about 30 hours. Ran one more time with power saving off and observed 28 hours. So each cycle with or without the power saving feature enabled well over a day so I believe this is a decent battery for the price paid. I'm knocking one star off for no NFC (which I knew going in) and the perhaps overstated capacity along with the possible (likely) life expectancy I'll probably get with these non-OEM batteries. I'll likely attempt to claim a warranty after months if it looks like the battery is beginning to fail just to see if the warranty is worth anything (my time and/or shipping).

So Far so good.Battery life seems to be decent.Best value for the cost.

Best value for the cost

For My Note 4

Battery life seems to be decent, especially with moderate to light use. Only had it for a couple of weeks. Need more time to properly evaluate.

It's nice got my phones life back to live another 4 years

I had to return this item and asked for a replacement. With the battery fully charged, and my phone turned OFF, the battery was below 10% charged the next morning! I will add to this, when the replacement battery is sent.
