Ability to add certain modules to extend the functionality of the phone; Multi-core processor and dedicated 3D-graphics, minimum of 1.5 GHz. At least 4 GB of RAM. Large capacity battery, larger than 3000mAh. High-speed internet 100 Mbit/s WWAN capabilities or higher. Has Hi-Fi audio capabilities built into the phone.
Then the phrase "electric battery" sounds redundant; it's like saying "electric electrochemical cell". Glrx 16:21, 29 May 2018 (UTC) Support move. "Electric battery" is a natural term, "electric" being drop when the context is already established, which is almost always the case, but is not for the title.

An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections [1] for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode. [2] The terminal marked negative is the source of electrons.
This is fair enough, so I have instead modified the article further to include a new section on the construction and chemistry of the battery based on what is stated in the scientific article alone, and re-edited the following section (which I suggest is "comparison with lithium-ion batteries" instead of "advantages" - no real prototypes of ...
The battery's polarity reverses and the anode becomes the cathode and vice versa. [ 1 ] The system's power density was some maximum power density of 60+-3 1 W m −2 (based on a single electrode), with a maximum energy density of 453 W h m −3 (normalized to the electrolyte volume), substantially higher than that of other liquid-centered ...
Martin Cooper, a former general manager for the systems division at Motorola, led a team that produced the DynaTAC 8000X, the first commercially available cellular phone small enough to be easily carried, and made the first phone call from it. Martin Cooper was the first person to make an analog cellular mobile phone call on a prototype in 1973.
An AA-sized alkaline battery might have an effective capacity of 3000 mAh at low drain, but at a load of 1 ampere, which is common for digital cameras, the capacity could be as little as 700 mAh. [12] The voltage of the battery declines steadily during use, so the total usable capacity depends on the cutoff voltage of the application.
