Does Bluetooth or phone speakers drain more battery?

Having Bluetooth turned on all the time won’t drain your battery any more than having Wi-Fi on when you’re not connected to a network directly. The problem with this false fact is that Bluetooth only uses your phone’s battery when it is being actively used.

What uses more power Bluetooth or phone speaker?

The results show that playing back audio over Bluetooth consumes essentially the same amount of power as playing back audio over speakers or headphones with Bluetooth turned off. On average, our devices recorded just a 0.2\% increase in power consumption when playing back audio over Bluetooth.

Does using Bluetooth Speaker save phone battery?

For Android users, it’s as easy as clicking on your battery icon and selecting the Battery Usage option. So, to sum it all up: Streaming media with Bluetooth might have a small effect on your phone’s battery, but just leaving Bluetooth running for background devices barely uses any battery at all.

2. Power down the device to avoid additional battery use.
3. Place your device in a cool, moisture-free environment that’s less than 90° F (32° C).

How much battery does Bluetooth Use iPhone?

When Bluetooth has an active paired connection to a hands-free device it consumes 2.5 mw. As the battery capacity of an iPhone 8 (not plus) is about 6900 mwh, if Bluetooth was the only thing using power the battery would run down in about 2800 hours, or about 3 months.
