**** The Official Note 4 thread ****

Oh,snap. They blew out the moisture indicator under the battery on mine and claimed it had drop damage - it didnt. I guess it was their way of getting out of replacing the screen on mine. It had a months warranty left.
 
After some research, I discovered many stories of Samsung wriggling out of warranty repairs. They wouldn't budge an inch on it, sounds like you were in a similar position. I fancy the note 8 but more likely the s8 plus, this time though, I will take out a separate insurance policy to avoid having to go near samsung again if it develops a problem. Screen on mine is perfect, just the motherboard that needs replaced.
 
After the brick bug on the Note 1, fire issues with others and the widespread eMMC failing on the Note 4 sadly won't be going Samsung again - but need to find a phone that fills the same niche.
 
What causes the eMMC issue though - is it cheap memory like I thought, that is reaching its peak no of writes or something else? It's definitely related to the storage chips. I haven't seen such issues on other Samsung devices.

I was wondering if it was like the 840 EVO SSDs where the cell voltages aren't being refreshed/calibrated for degradation over time which eventually makes a location slower and slower to read from causing issues when it becomes very slow and then finally becoming unreadable with a chance of cell damage - however that should be resolvable if you completely reflashed the phone periodically but I guess if that depends on some low level bootloader functionality that has to always be resident in the phone's memory it might still be the cause.

If it is the case then Samsung have been utterly contemptuous of the customer and instead of taking the hit from their own design flaw with storage based on the same design shuffled it sideways onto phones in the hope it wouldn't be exposed like on higher usage PC storage :s I hope that isn't the case but if it is they need to be held to account.

From my observations of here and other forums including Reddit what happens in 90% of cases seems to be that:

1. Note 4 fails
2. Owners buy the latest Samsung high end phone to replace it

Won't be the case here unfortunately - if my Note 4 dies from it will be the second time I've been bitten by Samsung eMMC issues and won't be happening a 3rd time. My Note 1 has the brick bug issue so while it hasn't died I can't update it, etc. without risking bricking it.

Sucks because the Note as the original incarnation is the perfect phone for me.

I'm sure that's a dig but remember those people might not have bought a high end Samsung to replace it had there been a credible alternative available.
 
A new twist in my years long battery saga, the phone now struggles to charge whilst in use :p (seems hit and miss). I did note I have been using fast charge for a while which I am convinced doesn't help matters. I think this battery is simply knackered, ordering a new one.....

Probably should order a spare battery just incase - think mine is a good bit over 12 months old but starting to seem like it isn't quite holding its capacity any more. Kind of a bit wary though that the phone will die due to eMMC issues anyhow making the purchase of a space battery a bit of a waste :s

Funny thing is I've a Sony Ericsson k750i that I use as a backup alarm and if I'm doing stuff where I'd be wary of losing or damaging a nicer phone - almost 12 years old now still going strong on the original battery. Probably should start to think of replacing it with something else as it will likely give up the ghost before too long I guess being that old.
 
I recommend the RAVPower batteries. I bought one very recently amd measured the capacity as the same as an OEM Samsung one. You can also extend the warranty by a 2.5 years although whether that's actually worth anything if it comes to a claim I don't know.
 
I said to my girlfriend last night, "no way the new battery could be worse". Bought a RAVPower battery, lost 30% on my way to work this morning :p
 
I've been using mine for the last 5 days and it's been fine. If you email the company that's selling it then based on previous experience they'll send you another and tell you to keep that one or alternatively offer a refund.

Edit: Just checked my usage today and it's used 2% in 4 hours. It's only been on standby in that time though.
 
Every day is a low battery day now. Got back home earlier but had to rush out with 15% so brought along my three previous Note 4 batteries in desperation. The one I put in 1hr 20mins ago has lost over 50% and at least 2% writing this post :p:p (make that 3%).
 
Just seen Soundhound is using my 5% of my battery, CPU time for 52 minutes despite not using it today. Problem is, using Greenify doesn't seem to fix it.

It just gets weirder. I wondered if the cable I was using might be an issue (cheapo 5in1 job), so I ordered some nice braided (and well reviewed) cables. The problem is they seem to charge my phone much too quickly, despite fast charging being off! I just saw a notification saying "fast charging". None of this makes sense. It reminds me of my unluckiness with CPU silicon lottery - always got those chips that wouldn't even do simple OCs. I have had some, stranger than normal, battery issues on all of my Android phones :p:(.

The phone charged 3% in the time I wrote this post.....
 
I charged my note 4 last night from totally dead. I ran the battery down to 0 using a drain app.
I then used a usb charge analyser, and was dismayed to see the charged capacity was reported as 1516 mah...
This might explain why my battery does not last as long as when I got my first note 4/edge devices 3 years ago.
Anyone else done a similar test with the note 4? This one was a refurbished unit from an insurance replacement about 6 months ago I think.
 
What's a USB charge analyser? Physical device or app? Keen to try out myself. I am currently using an old battery as my newest one seems just as bad as the rest. This old one drains about 1% a minute when used and probably charges about that rate with fast charging off. My newest problem (could be CSC/BL/ROM related but it's done it across two different ROMs and basebands) is my signal will just suddenly go in various forms; data simply does one but signal is there, signal goes all together and returns or the most annoying iteration - data and signal are showing but the data is completely gone and only a restart will get it back.
