Battery Life- Very good to excellent. Since I have done a few tweaks on this tablet, now I have found that my battery life is better than the first and even the second day.

The instruction set architecture (ISA) is a set of commands used by the software to manage the CPU's work. Information about the set of instructions the processor can execute. Where battery life is concerned: To make your battery last as long as possible is to be sure to turn off BLUETOOTH AND WIFI when you do not need these. Both are these are memory hogs! Also, I turn off my GPS and even SYNC sometimes to conserve battery and then turn them on later.

If it runs out of battery, you just recharge it thru micro-USB and it reboots. If profoundly discharged, you do not even get a "charge" indicator from the boot ROMs until reaching about 3 percent. otherwise no harm done.

The L2 (level 2) cache memory is slower than L1, but has a larger capacity, instead, which allows it to cache more data. Just like L1, it is much faster than the system memory (RAM). If the CPU does not find the data needed in L2, it proceeds to look for them in the L3 cache memory (if there is such) or in the RAM. EXTERNAL SLOT FOR MICRO SD CARD up to 64GB This is a must for me as I keep my personal files, photos, and music on my internal SD card.

The screen is absolutely beautiful! RESULT for me: It is that much clearer and vivid screen than I thought it would be with truly amazing clarity! RAM (Random-Access Memory) is used by the operating system and all installed applications. Data in the RAM is lost after the device is turned off or restarted.Information about the number of pixels per centimeter (ppcm) or per inch (ppi) of the display. The higher the pixel density, the more detailed and clearer is the information displayed on the screen.
