The battery meter shows your percentile ranking of your best score compared with other players in your age range on their first 3 times they play the game. As an example, a percentile score of 60 means you scored better than 60 percent of people in your age range. Fifty percent of all players in your age range will score between 25 and 75% on the battery meter. If you are in this range, you can think of your brain as being adequately charged with this skill. If your score gets to over 95%, you can consider your brain to be supercharged for this skill. Keep practising to see your battery meter go up as you get better with the skill.

Percentile Rank Classifications
99.6+ - Extremely Advanced
98-99.5 - Very Advanced
91-97 - Advanced
75-90 - High Normal
25-74 - Normal
9-24 - Low Normal
Less than 9 - Needs Improvement

Some skills take longer than others to show improvement with practising. For example, you may show an improvement with several of the games in only a week, but it may take several weeks to improve with games like Vocabulary Star. You will be learning new words as you play Vocabulary Star, but only a small percentage of the total database of words are included each time you play.
