At medium volume and with minimal lights, the<strong><u><a href=\"https:\/\/www.batteriesfast.co.uk\/bluetooth-speakers-battery\/JBL\/GSP-ICR2S4P-PB350A\/1747418\" target=\"_blank\" rel=\"noopener\">JBL PartyBox 310 Bluetooth Speakers Battery<\/a><\/u><\/strong>&nbsp;degradation isn&#8217;t significant. One user reported that at volume around 10\/16 with lights on, the battery dropped from 100% to 77% in 4 hours, a relatively acceptable rate, indicating that normal aging won&#8217;t be particularly severe over a considerable period. Under high load, the degradation is noticeable: tests showed approximately 6 hours at two levels below maximum volume with lights off, approximately 4 hours at 50% volume, and possibly 4 hours at very high volume. The perception of &#8220;not being durable&#8221; at this point is largely due to the high power consumption from loud volume and light shows, not solely due to&nbsp;<strong><u><a href=\"https:\/\/www.batteriesfast.co.uk\/bluetooth-speakers-battery\/JBL\/GSP-ICR2S4P-PB350A\/1747418\" target=\"_blank\" rel=\"noopener\">JBL PartyBox 310 Bluetooth Speakers Battery<\/a><\/u><\/strong>&nbsp;aging in the JBL PartyBox 310. Other isolated issues include: suddenly being unable to charge after more than a year of use, or the device failing to power on after a few days of use. These are quality issues rather than normal degradation and require after-sales service.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Volume, lights, high temperatures, and frequent deep charging and discharging all accelerate battery degradation or amplify battery anxiety. Overall: Under light to moderate use, battery degradation in the JBL PartyBox 310 is not noticeable over a considerable period; heavy use with loud volume and light shows results in a significant reduction in battery life; sudden inability to charge should be considered a malfunction.
