Something "funny" happening to me last week. Both mine & my wife's Note 4 battery going kaput. I bought my wife's on 24th October last year & mine around 3 weeks after that. While connected to the charger, it can be turned on but once disconnected, it will having never ending series of bootloop, stuck at Samsung logo & then restart itself again & again. Planning to get Note 5 at the end of this year but now I'm afraid of the same thing happens with sealed battery. The repair cost will of course high if it off warranty.

Now planning to buy new battery, but just AAA as the original one too expensive. Does anyone using AAA Note 4 battery before? Does fast charging works well with this battery?

Original battery+charging case is RM180 here but unfortunately, I'm a little bit short of fund now & I really need my phone for work now . Already got an AAA battery for RM50 with 3 months shop warranty & it works just fine with fast charger. Will change to original one at the end of this month as I'm also not very confident with it, hehe.

BTW, already upgraded to 5.1.1 using wanamlite rom & I'm quite shocked to see the performance. My Note 4 flies. Coming straight from 4.4.4, I feel everything is so snappy now. Recent app button react quickly after being press. No more 1-2 second waiting.

Yeah, yeah, I'll change to the original soon, hehe

I'm flying straight from 4 4.4 to 5.1.1, all I can say is it the most worthy upgrade for Note 4. You'll love it.
