Nasel jsem zahranicni recenzi, kde uvadi ze Charge 4 s baterkou 7500mAh zvladl fungovat realne 8,5 hodin na 60% hlasitost. 6,5h na 85%. Udavane 20h vyrobcem je velmi potichu. Byla by zde realna zkusenost, kolik to realne vydrzelo hrat? Treba celou noc nebo den? zde je nalezena recenze, tak nevim zda verit recenzi a nebo udaji az 20hodin External Link lists a battery runtime of 20 hours, but these numbers are calculated at extremely low volumes. My real world tests garnered these results
