For all of these "Removable battery is a must!" people, are you all just going to stick with a note 4?
How long do your extra batteries last in your pocket? One guy said in a tropical storm, he could use batteries to get him by for a week..... Yeah right. How many spare batteries do you keep? 9? If the phone is your only electronic working, it will be a dead battery in 6 hours from constant and continuous use. You will need about 18 to make it a week with no charger. Disaster plan, this is not.
An external charger is too bulky but a pocket full of batteries is not? This is huge stretch here. For the guy who has no charger at work, so he comes home and pops in a new battery, then he can head back out right? Well, what are you doing on the train? Plug in that external charger. What if you drive? Plug in your phone. What do we non Samsung users do? Well, I dunno, we make it though.
20+gb of music, 15g of movies, 12 GB of pictures, and 5 GB of docs your SD card??? Whoa. Packrat much? You trust all of that to only exist on your phone? This is poor planning. Phones are too little. Phones are lost, stolen. dropped in toilets, etc. Why is your whole life on your phone only?
You can't pop a hot battery????? Why is your battery hot? The only phone I ever had this issue with was my Epic, GS2 and GS3. Once I left Samsung, I never had this issue again. This is not a thing with the rest of the world. Your phone should never get so hot that you need to pop your battery out and run away before it explodes.
I remember from my Galaxy days, that the SD card kept getting scanned, constantly, causing a wake lock. I think the was "Media Scanner" under the battery stats. My phone did it, wife's phone, best friend's phone, both kids' phones. All of them. We all had to constantly remove the SD card, reformat and put the files back on one by one to see what file was causing it. This was even an issue on all of our Galaxy Tabs. Once wewent Nexus and Moto X, this never happened again.
SD cards are great ideas, but terrible with these Android phones. Removable batteries and SD cards both are not needed. Wireless charging is a great addition to the puzzle also.
Besides the above, where you all going to go? What will you do? What phones has SD card slots anymore? Note 4? Older LG phones? Chinese phones?
