Bluetooth battery drain problem - Huawei P9 Questions & Answers

Hello. Am I the only one with that problem? My Bluetooth eats more battery than screen.

What kind of devices do you have connected?

Sometimes Bluetooth 4 has compatibility problems with older Bluetooth devices. Maybe you could try turning off one of the devices and check if the battery drain is still there. Things like this can be fixed with a firmware update in case Huawei is going to publish one in the future.

I don't know but maybe​ this could actually be a hardware problem. Don't know how to be sure and if it would be worth it to send the device in (in case you still have warranty).

My device was on warranty like 2 months ago because my charging cable Has burned and everything was fine

I think reinstall fixed my problem

Problem od still on. I didnt even turn on Bluetooth.

Guarantee, seems hw related..

Kinivo BTH220 Bluetooth Headphones NOT Compatible?

Weird, my Nexus 10 can't find the Kinivo BTH220. These are very popular, inexpensive bluetooth cans. From Amazon reviews they are reported to work with Nexus 7. Anyone else have problems? I'm stock for now on the Nexus 10.
Tried to pair my Kinivo BTH220's as well - same issue. Doesn't find them. I'm too much of a noob to offer a solution but wanted you to know you're not alone with this question. Wonder what's going on with the N10, they work perfectly with my phone...

Don't know enough about Bluetooth. Possible the N10 doesn't have the right frequency or radio to support these headphones?

Incompatible bluetooth stack?
Oh No...this is not compatible with Google Nexus 1.
OMG. Is this headphone not compatible with Android devices?
My google nexus one (rooted) is not able to discover the headphone at all.
Is this headphone only working for Apple products and Windows 7?
On the manual, it should work with Android devices though.
I'm hijacking this thread since I searched the forum for bth220, but my kinovo's aren't working on my HTC One X+. Can pair with my car.
Hmm, not sure what's going on, but I have those headphones and they work great on my nexus 10.

I found this from a review on Amazon: ... I contacted Kinivo when I had some difficulty pairing the headphones with my Nexus 10. It turns out the pairing difficulty was my fault (I was making the Nexus 10 bluetooth visible to devices but forgot to also have it search for devices). Kinivo responded almost immediately and walked me through the correct setup. Bottom line, buy the Kinivo product, you won't be disappointed!
Update: I tried again with Nexus 10 and paired ok. I'm not sure what the problem was.

I used it with my GS3 just this morning. Try this. Turn off the headphones. Enable bluetooth on the phone. Hold down the power button on headphones for 10 seconds or so until the lights flash. On the phone scan for new bluetooth devices. It should pair.

How is the sound quality with the s3 ?
I have these headphones and they work fine on my Nexus 10. I also have the newer model the 240 and they also work fine...

It just ok. Cuts out occasionally when not fully charged. I still use with an S3.
These headphones are great. I have 2 sets, one at work and one at home. The company is awesome too. A friend of mine had a pair crap out on him and Kinivo sent him a replacement free of charge and didn't even ask for the old ones back.

Repair it with Sony Update Service.
Updated 4 days back
Build no 10.1.1.A.1.253
Sent from my C6602 using xda app-developers app
Try a factory reset. But before that check if rebooting solves the problem. I had a display issue which was fixed by a reboot.

not telling you to update, "repair it"
Using different chargers is the cause.
Use the stock charger with stock cable.
Sent from my C6603 using xda premium
I have the same issue, and I don't use the stick charger, I imagine the problematic chargers aren't correctly grounded or have some EMI or ESD issues. I haven't tried the stock charger yet to see if it solves it.
Poor move on Sony's part though not making the phone able to handle a poor quality power source correctly.
Sent from my C6603 using Tapatalk 2
before i used to charge using the car charger. at my cousins place i used a htc charger for 4-5 days.
from later on im using the stock charger itself..
did i restart .. no use..
same issue... i selected show touch from development options..
im able to see the responses.. this occurs only sometimes , may be every 7/10.
just a single touch and the whole line gets multi touched.
for ex- i try to type "hie" , i get something like "ghjuioert" some times even bigger messages.
no difference even after a rebot.
should try factory reset. (long process backup download etc ).
any other options ?..
im using the stock charger...
tell me how to repair it...
With pc companion or sony update service.

Hi dude !
I remember to have this problem on my Xperia Neo.
While charging the touchscreen was unresponsive like touching on one side was like touching on the other side, apps opening randomly, lots of bugs. But didn't happened always, only sometimes.
I never figured out what could be and I don't use it anymore.
Maybe you have a faulty unit

Bluetooth issues

Anyone else have issues with bluetooth and calls?
When I'm in my car, it cuts in and out and is almost completely useless as a phone. Don't remember it being like this when new.
Att is sending me another phone to see if it does the same thing.

Are you using a Bluetooth headset or one built into your car or one of those aftermarket car Bluetooths?
My Bluetooth headset has been working perfectly with it so far.

Skipping effect in the car for me. Also have a hard time getting my BT headset, a Plantronics Backbeat Go, to sound right. It's very "canny" sounding until I make a phone call (an old trick). Car connection is an HTC stereo clip.

both my car ('13 vw gof tdi, stock head unit) and my headset i use in the office (lg hbs 730) seem to work fine, not sure that helps though.
This happens for me if I have my Gear 2 watch paired with it and it's streaming music in my car. It'll cut out for a second and it's not a notification.

It doesn't occur with music, just calls. Getting new phone tomorrow so it will hopefully be resolved.

Afaik it wont be resolved with new phone as well. Its a bug in kitkat. Only way to fix this is turn wifi off when connected to bluetooth and driving.

Is it a bug with kitkat on TouchWiz? I had a nexus 5 before this and never had this issue. Will try turning off wifi and see if that does anything.

I have a nexus 4 previously and now a moto x and s5. Everyphone has this issue.. My problem is when i am on call and driving for some reason i can hear others voice but others cant hear mine. If i switch to ear piece and back to bluetooth it works just fine again for sometime. So i searched a lot and found that turning wifi off solves the issue. It works for me atleast

I'm not doubting your experience at all. Though, I will add that I always have wifi off in the car when connected to Bluetooth (profile scheduler turns out of four me), but I still get the music shipping problem.

If your music stutters then it might be a problem with memory. Trying freeing up memory with clean master. Also check what process are running in settings>applications and kill some apps which are not useful for you. Try it.. Hope it works out for you

Audio Starts Loud Then Lowers

So my best friend just got a Nexus 6 not too long ago, but seems to be facing an issue where all Music/Sound starts playing loud when you first start it but after a few seconds the volume becomes very low. We have flashed custom roms as well as used stock and still face the issue. We have searched the forum threads and cant seem to find anything that fixes it.
Any help would be appreciated.
I had this issue and replaced it no problem. This motorola qc is really bad

Hi,
@VeryCrushed , @Tsoflyyup
I have the same problem, Can you try to connect the charger and see if the problem persists? My phone seems to have this problem when the charger is not connected and the battery has a low level.
I had the same problem. However, as soon as i use any custom kernel everything is fixed.

Yes Iv tried turning the fast charge option on and off multiple times but still no luck.
When I plug in a cable the fastcharging animation appears for a second,then it 're shows the animation and says cable charging. Which is strange, I can also not charge my phone when the phone is turned off completely.

Do you have another cable? Only saying as I've had another cable that stopped working with fast charging. The part that you can't charge whilst switched off is strange.

Yeah ok, that sucks man sorry to hear. If it helps there's really no difference in charge time between fast and normal. I have used just a plain 2.1amp charger plugged in and also an old Nokia wireless charger and we're talking a few minutes difference. The fast charge is really only a gimmick.

The real fast charging kicks in when the screen is off. And it's definitely a lot faster.
