[Nexus 7 Themes and Apps] Spannaa:
The stock battery on the Nexus 7 only changes icons at 0%, 15%, 28%, 43%, 57%, 71%, 85% & 100% charge so I've modified it so that there are now icons for every 1% and they're also animated when the device is charging.

To do this, I made two sets of Base VRThemes which modify SystemUI.apk:

The first set are Base Statusbar Battery VRThemes which change just the statusbar battery icons and contain a modified res\drawable\stat_sys_battery.xml, a modified res\drawable\stat_sys_battery_charge.xml, the 202 1% statusbar battery icons in res\drawable-hdpi & larger versions of thes icons in res\drawable-sw720dp-hdpi for tablet mode users and a modified resources.arsc

The second set are Base Statusbar Battery & Pulldown Battery Toggle VRThemes which change the statusbar battery icons and the pulldown battery toggle battery icons. These contain a modified res\drawable\stat_sys_battery.xml, a modified res\drawable\stat_sys_battery_charge.xml, a modified res\drawable\qs_sys_battery.xml, a modified res\drawable\qs_sys_battery_charging.xml, the 202 1% statusbar battery icons & the 202 1% pulldown battery toggle battery icons in res\drawable-hdpi and a modified resources.arsc

The new resources.arsc is needed because it contains the modified res\values\public.xml file with the info about the battery pngs. Unfortunately, adding this file makes the base VRTheme rom specific.

If a Base Statusbar Battery VRTheme has been flashed, Battery Universal VRThemes can be flashed over the top to change just the statusbar battery icons.

If a Base Statusbar Battery & Pulldown Battery Toggle VRTheme has been flashed, Pulldown Battery Universal VRThemes can be flashed over the top to change just the pulldown battery toggle battery icons and Battery Universal VRThemes can be flashed over the top to change just the statusbar battery icons.

These VRThemes have all been tested using both TWRP & CWM recovery and multiple Universal VRTheme flashing is supported.
