I went to my Chinese websites, looking at the 10 000mAh Oukitel K10000 phone. Nice size battery.....but I couldn't find any other model than 2 GB RAM and 16 GB ROM !!!!!
I don't care how big the battery is, but I won't get duped into buying a smart phone with 16 GB of ROM again. After the operating system, there is barely enough room for your apps......let alone your music collection, pictures, videos etc.
I was duped by Samsung into buying two of their top of the range tablets, that were limited to 16 GB. They convinced me that the external SD card will fill my needs. No way - external SD cards are nice to have, but not a replacement for internal memory. Lots of apps refuse to be moved to the SD card, data gets deleted, sometimes SD card access is restricted on some versions of Android. And...SD card use is much slower than internal.
So...I would love a large capacity battery - I don't care if the phone is thicker or heavier than others......but I refuse to accept 16 GB ROM and 2 GB RAM. Minimum I would look at is 64 GB or better yet 128 GB. I bought a Leeco LeTV LE MAX a few weeks ago that has 4 GB RAM and 128 GB ROM for about $ 220. Now that is decent storage capacity...
