USB or Bluetooth - which one eats more battery life?

Hey Guys!
I wanted to know which one will eat more and quicker battery life:
1.wired usb controller
or
2.bluetooth controller
android version: 4.3
thanks for your answers!
Hey sorry to be such a bummer but which app are you using to use ur phone as a controller. My opinion on your question is that bluetooth wd logically thinking here, bluetooth wd use more power. As a usb cable plugged in your phone wd or shd be charging at the same time. If u finding it difficult to tell maybe the usb port is not pushing out sufficient charge power. I wd then maybe plug into a normal phone charger and use bluetooth. I find if I use a bluetooth controller eg androg I put my phone in flight mode and then turn bluetooth on and my battery lasts longer because the phone is not continously searching for network when signal is low. But via usb ur shd be charging and via bluetooth no wires connected ur obviously using power. And wireless devices that communicate with each other tend to use power at a faster rate. If using as game controller over bluetooth maybe disable the vibrate function if it has one. Thats my personal opinion so if u dont mind cables then usb the phone... I dont mind bt via my s3 its convenient and its not like im gna play nonstop for hours on end. But id rather have a charged ohone shd I nd to up and leave all of a sudden... best of luck... whats the usb controller app?

I dun think usb wired controller chargers ur phone... Like if u plug an external hard disk to ur phone thru a converter plug, the external hard disk will not charge ur fone.

OTG and charging

Hello everyone !
I would like to know if it's possible to use OTG and to charge the phone AT THE SAME TIME ?
Maybe with a specific cable, or a docking station ?

With magnetic cable,why not?
So it's possible to use the magnetic cable to charge the phone and to use the otg cable at the same time ?

Thanks for the answer.
Do you use it "a lot" ? No problem with that (no disconnection, etc.) ?
Been using it regularly but not with a dock or magnetic charging cable.. using it on an external battery pack that connects on the same dock port so it is still the same.
I can safely say that it does not give any problems with OTG at the same time..
It is possible to charge via an OTG cable, but the cable have provision for this thing exactly. There are guides on the internet, google it, i'm sure you will find what you are looking for
Just to confirm that I can charge the phone with the magnetic cable and use a USB device at the same time .

Using as GPS & Music in Car - Charging Help

I own a old galaxy tab 10.1 that's doing nothing in my bottom drawer. So I thought let's get some use out of it by making it the music and gps in my car.
When I plug it into my usb car charger, I get the red x and it doesn't seem to charge. Can someone tell me what I need to be able to charge the tablet while running music and GPS in my car?
Will this work?
http://www.amazon.com/gp/product/B0...=QZZM8W8MDZZ3RXK3YA1G&ref_=pd_lutyp_cxhsh_2_1
Will I need anything else? maybe this?
http://www.amazon.com/Air4tech-Samsung-Charging-Accessories-Guarantee/dp/B00EIKHJAW
Any clarification as to what I need is appreciated.. Thanks!
The red x means it isn't charging. Best way is root it and install a custom ROM or kernel to avoid this problem. Otherwise you'll have to use the official charger and a 12v-220v converter...
My plan was to root so that I could run all apps in the dual view mode. So rooting it will also allow the device to charge with car charger (using the OEM cable, but 2.1a usb car charger)?
Rooting alone won't help. A custom ROM or kernel will.

Asus ZenPad Z380KL - problem with charging while using OTG

Hi guys, I have a problem with my Asus Z380KL tablet. Im want to use this tablet as a head unit in my car and I need to use OTG cable to make it work, also I need to have charging in the same time. I also want to use AutoMate app to control tablet, especially auto on/off while charging/not charging.
And now is the problem, I can easily achieve working external devices (usb dac, FM transmitter and pendrive) with charging in the same time, problem is when I cut off the power from charger tablet still thinks that is charging, of course it cant be cause there is no power source but still I can see charging icon and in settings showing that is still charging. It stop doing that when I unplug micro usb plug from tablet but obviously I cant do it all the time cause tablet will be build in dashboard.
Now, with normal charger, without OTG cable its working perfectly, when I cut off power it stops charging in the same time, also I tried couple OTG cables and on every single one is the same thing.
Any ideas guys how I can fix that? Im not sure if thats software of hardware problem.
Also device is not rooted and it has ASUS oem software with Android 6.0.1.
Thanks guys for your answers and your time! Cheers

Really nobody knows what could be a problem?

Poco F1 MHL / HDMI ?

Hi !
Before buying the pocophone F1.
I need to know if we can connect the phone to hdmi tv.
MHL ? dp alt mode (display port alt for android)?
Is there any way to display the pocophone on tv ?
I want to use this feature to play emulator on big screen, and on the go.
If someone can try this for me... Thanks !

There is a "wireless display" option which will allow you to mirror your phone screen on your wireless TV. The image quality is not the best but it does the job.

That function works really nicely with my Chromecast.
I gather (though I've not tried it) that usb-c allows cabled screen mirroring too, if that's your thing.
Hey ! thanks for your answers. i don't want a wireless solution (already have a chromecast) but too much lag for gaming...
I need someone to confirm (and tried it) that i can connect a USB to HDMI cable in order to mirror screen the phone on tv.
Thanks
@F4T4LITY
As above, I've not tried it, but here's an interesting link to some info on usb-c and Alternate mode. It kind of suggests that any phone with usb-c, given the right cable can do the trick.
This would do it, I reckon

Thanks for the link buddy ! I check that !
EDIT : it's not for all phones, the usb c port of the phone need to be compatible with alt mode (display port alternative mode), then just a cable usb c to hdmi will work.
But with all my research i can even know if the poco f1 hac a usb c port supporting the dp alt mode...
I saw an interesting way, with display link adapter. It s usb external graphics cards, mirroring your phone on tv. But the problem is, with android phones and this technology, you can't mirror on tv AND charge your phone at the same time... :/
If someone has tried something else to connect the poco f1 to a tv.
Let me know, even if it s a fail !
Thanks guys !
EDIT 2 :
For information : I bought my poco F1, i ll get it tomorrow with the hdmi adapter.
I will post you the answer to the question : is the pocophone capable of mhl, dp alt-mode or hdmi out.
i will give you also tomorrow the links to the cables i bought for the test.
If the adapter doesn't work, i will buy a Display link technology adapter, then i will say you if we can charge at the same time as mirroring to the tv.
See ya !

OK i ve done the test ! the USB C to hdmi cable DON T Work with pocophone F1 !
There is no MHL, Dp alt mode in the pocophone !
I will buy now a display link device (usb external graphic cards) to mirror my phone throught HDMI.
I ll keep you informed if i can mirror hdmi AND charge at the same time with the "display link" device.
See ya !
Missed it by that much....
I tested mine out on USB-C to HDMI this morning too but F4T4LITY beat me to it....
Confirming it didn't work...
Bummer! Wonder if some bright spark might work out a kernel hack or some other workaround to get this working? I just found a thread on Mi forums asking about it so plainly others are interested...
Might be worth submitting a feature request for a future update. Do other Xiaomi phones have this?

unfortunately, it s a hardware issue... in the poco F1 usb c. none update can change that.
But For info : I don t need to buy a display link hardware. I bought a Chromecast ULTRA (with the ethernet port) and it work flawlessly even in gaming.
My poco F1 >> Wifi 5Ghz >> Chromecast ultra (ethernet)
I can mirror my phone and charge at the same time ! no more problem here for my use !
It s a shame to don't have mhl or hdmi on phones today... it must be standard... but i got the chomecrast backup solution so... it s ok.

#ro.hdmi.enable=true is commented out, maybe some can investigate what it does if enabled
any news yet?
I'm interested too.
Up .. Any news ??
Sry guys nothing works with cables for now...
Got the ultra chromecast solution and sincerly it does the job. I can play ppsspp, or gamecube, psx,...... Full speed even on tv (wireless) or on the pocoF1.
Found out Poco doesn't support TV out after I bought it. My USB C-HDMI dongle was working flawlessly with LG V20 but not with Poco F1. My Tv doesn't have WIfi inbuilt so can't mirror wirelessly either. Bummer! Now only two options are there either buy Miracast/Chromecast dongle(wireless) or Displayport dongle(wired). Removing important useful functions doesn't really make cheap phone appealing.
Edit: Also, I found these dongles for cheap online. If any one has one can he/she check? https://www.aliexpress.com/item/NEW...splay-Graphic-Adapter-for-PC/32824881352.html
Got some USB-C earphones, it was a whim, they also aren't supported by the USB-c port....
This looks to be another cut corner to reduce the price , though is it hardware or software?
There may be a chance if it is only software....
