    Thinking or hope it's just battery. My 2 year old Note 4 original battery dies at anywhere between 20 to 40 percent battery life. Was told might be a software issue. What's anybody else experience with this. If is battery what brand battery did you replace it with and are happy with it.

    I ran into that problem about 6 months ago. My phone would shut down when it got to about 25-30% battery consistently.

    I replaced the original battery with an Anker battery from Amazon for about $20 and my phone has been working normally every since.

    For me this is the reason why replaceable batteries are so important. Had it been my wife's S6 I would have had to take it in somewhere to have the phone opened up and then hopefully put back together in one piece!

    Thanks Chet, I'm going to look into new battery to hopefully tide me over till Note 8. Was going to get a Note 7 but that went poof, now waiting for Note 8. I'll miss my Note 4 for its removable battery.

    The stock battery is just complete garbage. I got 2.5 hours on mine until it hit 50% and shut down.

    Yes this happened to me. Fixed with new battery then after 6 months started doing it again with new battery. Got another battery and turned off fast charging and haven't had the problem since. I think fast charging damages the battery.

    Although the battery issue can seem to be related to the "battery" it's actually an issue with the Note 4 system. Changing the battery will not relsolve it. It will seem to be a fix if you change the battery but, the system shannanigans will reappear. You'll have to factory reset it or replace the phone.

    And, where exactly do you get this information from? What "shannanigans" do you think the Note 4 system has concerning power dropping out as described?

    My Note 4 is 3.5 years old and I've seen this happen with spare batteries before. Change the battery and naturally the problem goes away... unless you happen to put another bad battery in there. This drop out issue is nothing new with lithium batteries... in any device. Or, do all devices have "system shannanigans"?

    You need to change the battery every 18 months or so. It's just the nature of the beast.

    Don't buy the cheapest, it'll be a fake. I also don't trust small retail shops/setups. They often sell counterfeit stock.

    My local shops got hit by the Police in Scotland recently selling fake iphone chargers and leads. They took away a ton of stock. If it's a fiver, don't buy it....
