View 8 system meters by toggling through 2 to 4 screens depending on resolution: Battery Meter: Level, voltage, temperature, charging status and speed, warning messages such as too-hot, too-cold, or too low for certain functions such as camera light, WiFi, or calls. Status periodically rechecked. Memory Meters: Both RAM (volatile) and Flash Memory (non-volatile) are reported, with percentage graphs and details on how much is free, allocated, used for objects, transient objects, other transients, files, or other (i.e. device software) purposes. Refreshes frequently enough for active monitoring of activity without burdening the phone too much with collecting statistics. Object Meters: System (Java Virtual Machine) object statistics are presented in two percentage graphs with details on the distribution of objects across RAM, transient flash, and persistent flash memory, and the number of Object Handles available, free, and used by transient and persistent objects, and linked directly to code modules. Filesystem meters: Shows used and free space on the internal file store and media card. Code Module Memory meter: Some phones have a separate memory for application modules, others reserve part of the main Flash Memory, so the correlation with the main Flash Memory can vary, but this meter reports the amount of space used and available for installation of applications. Object handles are a critical system resource that can be consumed by problem applications causing the application or phone to hang up, and this meter can help track down the source of such problems. While running, this app keeps requesting that the system do garbage collection as often as reasonable and beneficial, which frees up memory and object handles soon after they're no longer needed, rather than letting them run out first. This makes the meters more accurate, as they show what's actually available in a practical sense. Any meter that does not do garbage collection will give misleading readings, as much of the apparently allocated memory and handles are effectively free for use as soon as needed, but don't appear to be.
