Does Bluetooth 4.0 drain iphone battery?

[TorontoSS]

Hi - I recently bought some headphones (which I love, Sennheiser Momentums). I have noted before I bought these, that the battery on my phone has been going down a lot.

But I've noticed it even more lately. I'm not sure if it's using Bluetooth which does it. I have an apple watch and the Bluetooth doesn't drain as fast with that. Could it be the combo of streaming from Apple Music and the headphones using 4.0 Bluetooth?

Does BT 4.0 drain faster than 4.1?

I use BT 4.1 with a pair of LG HBS-760 - doesn't seem to drain noticeably faster. I mean, sure, it's going down faster than if it just sat there without use but it's not terrible. I use Google Music.

How old is the phone? Most phone batteries will start to degrade noticeably after a few hundred charge cycles.

Thanks for your reply. From my understanding (through google searches, I really don't know much about this), BT 4.1 works with 4G a lot better and therefore less drain. Whether it is noticeable is what I'm trying to figure out.

My phone is not very old which is why it's weird. I have an iPhone 7 which I think I bought in October or November. So it shouldn't have that many charge cycles on it.

Thoughts?

Are you streaming when using these BT headphones? Streaming will cause your battery to drop faster than having 20 BT devices connected.

My BT has been on from the introduction day of the 7+. It uses very little power when not in use. Not really worth turning off for me.

Nope. It's self sustaining. Like cold fusion.

Thanks - I don't understand what's causing my battery drain issue then. About 36% of the days issue is Apple Music however. I am streaming yes, HOWEVER, I haven't streamed for about 4 hours and it still is draining. The usage time and standby time are the same. Hmmm

Its usually Find My iPhone and iCloud constantly trying to UpLoad Data in the background or worse using GPS all the time to update the phones location. If those 2 are off then Take it to the Apple store for a free Diagnostic sounds the Lithium Ion battery chemistry is bad these batteries are fragile and chemically degrade even under perfect conditions.

Thanks,

I think I'll take it in and figure out the issue!

The only way to definitely answer your question is to try streaming from your phone for some time with wired headphones, and then repeat it with bluetooth. Bluetooth definitely uses more battery than the aux would, which is to say, no extra battery drain.

Differences between 4.0 and 4.1 should not be causing drain.
