Does using Bluetooth earphones eats away considerable amount of phone battery, considering phone’s phone’s bluetooth will be always on?

And assuming earphones are used daily for 3 hrs for calls and 2 hrs of music.

If yes, how much additional (approx)? 5%? 15%?

PS: Not sure whom to tag? Is there a list of DD members category wise who specialize in certain kind of knowledge here? Say X,Y,Z specialize in mobile knowledge and so on.

Yes bluetooth ones comes more power in comparison due to the bluetooth module which broadcast the signal but that consumption is very negligible.
But main issue is ideal period when you are not using or listening as during that time also bluetooth will be powered while in case of wired one there will be no power draw.
Also that’s pretty common for bluetooth users they never turn off the bluetooth.

The below is applicable if you are using latest phone/bluetooth version.

Bluetooth uses your phone’s battery when it is being actively used. And even then, thanks to Bluetooth Low Energy (BLE), the consumption is negligible. If the bluetooth is just enabled but no active devices connected, then bluetooth goes to sleep/idle mode.

If both the source and the sink support BT LE (Low Energy) i.e. BT 4.1 and above IIRC the additional power consumption just due to the BT radio being on is minuscule. I keep a BT mouse connected to a Redmi 3s all day and BT consumes an extra 1-2% over the entire day. After a few minutes of in activity the mouse powers itself off.
During use for voice calls and streaming music locally an additional 1-2%/h in my experience.

It would be negligible

Generally, Wi-Fi systems use more power than Bluetooth, typically 20 mW compared to 1 mW. normally Bluetooth is fast-enough – we open Youtube HQ with no lag – instant messaging and web-browsing is fast and responsive via Bluetooth.
WIFI Youtube test summary: Total battery life was 5 hours and 6 minutes (total 306 minutes).
Bluetooth Youtube test summary: Total battery life was 6 hours and 26 minutes (386 minutes).
This means when using Bluetooth on Android in our test, battery life was about 26% longer than WIFI.

Playing audio through the headphone jack, airplane mode, background app refresh off. In 7:59 the battery went from 50% to 34%, 2% per hour.
Playing audio through the headphone jack, Wi-Fi off, bluetooth off, background app refresh on. In 8:04 the battery went from 50% to 31%: 2.4% per hour.
Playing audio through the headphone jack, Wi-Fi on, bluetooth on, background app refresh off. In 8 the battery went from 44% to 23%: 2.6% per hour.
Playing audio over bluetooth, Wi-Fi off, bluetooth on, background app refresh on. In 8 hours the battery went from 72% to 45%: 3.4% per hour.

So with just 3G and bluetooth on the standby time would be a week and with 3G, bluetooth and Wi-Fi on six days. In other words: having bluetooth on uses an extra 5% of your battery each day, and bluetooth + Wi-Fi 7% per day.

Max its gonna be 1-2% battery drain via Bluetooth (3hrs call + 2hrs drain)
The top most battery drainers are obviously the screen & the Apps

Refer your phone’s battery usage stats to get some idea

As mentioned by others, bluetooth battery consumption can be neglected in comparison to wifi & screen.

Hi, I have purchased this (https://www.amazon.in/dp/B08BFGBY7W/ref=cm_sw_r...) product for my poco m2 mainly for calling purpose, but the person at other end is hearing his own echo. I tried this earphone on other phones and there is no such issue with other phones. Any workaround to fix this? @guest_999 @LIMBO  @andromeda @getready anybody

@smz

Not sure
The sound effects mode only works with Wired Earphones
You can try changing the BT codec from AAC to SBC or vice versa (via developer options) if the BT earphones support these (Majority of the basic BT earphones have only SBC)
Also try changing channel mode from Stereo to Mono and vice versa

Go to sound setting in phone/bluetooth to see if there is something called noise cancellation or some sound effect etc is there & try turning it on/off.

@getready :- channel mode is fixed to stereo and codec to SBC. If I try changing to mono or AAC, it doesn’t seem to be changing. After I change, and press back option and go again to developer options, it’s back to old one (stereo/SBC).
@guest_999 :- can’t seem to find noise cancellation.. Sound effect on/off doesn’t seem to work.
Anyway thanks

@smz Compatibility issue.. this is the problem with generic products (Earphones only got SBC support)

Either replace earphones or use it with a different phone :/

Any way to find out before purchasing whether these will be compatible? (https://www.amazon.in/dp/B08SC3DGRG/ref=cm_sw_r...)

Looks like it is MIUI issue
There are similar complaints for many other Xiaomi devices
