Bluetooth problem on mi a1 - Xiaomi Mi A1 Questions & Answers

Hi all.
I m on latest official android 8.0 with January security update after January update my Bluetooth option get automatically on.too much battery drain takes place.
Any one facing same issue.????
Waiting for solution.
Thanks in advance.

No, works perfect, not much drain.

I have big battery drain as well when Bluetooth is activated at all times. When I turn it off manually the battery consumption is back at normal. I didn't have the problem with the first oreo update which had December's security update.

Recently I am facing the same (or similar) issue.
Whenever I unlock the screen - the blutooth icon is ON and goes off after maximum of 1 - 1,5s (sometimes it is faster, a blink of an eye)
How can I identify the app/process turning it in? My battery consumption was very satisfactory up till now - now it is drained much faster

Same problem with me. My bluetooth get turned ON automatically. I have to manually switch it off. However, it again turns ON after 5 mins. I play mobile legends and the game works damn slow when the bluetooth turns ON. I need to get this problem fixed ASAP so that I can play my game with out interruption!

Battery Drain on XDA II

Hi,
I have a very recently purchased XDA II.
I was under the impression that the battery time was considerably improved.
Although I have turned down the backlight brightness when on battery power, it still starts to loose power when I receive or send a SMS for example.
Is this normal or do I have a duff battery ?
Steve
try turning off bluetooth when you dont use it
it's suppose to be a batt hog
Yup,
done that. I only have BT on when I am actually using my headset.
Any other idea's
Steve
when does it auto turn off ?
when does the backlight turn off ?
are there any SD cards connected seem to recall that they eat batt aswell
I've had mine a week, have the same power drain problem. After charging it all last night I managed to use it as a PDA for a total of 40 mins over a 6 hour period today before the battery drained. No phone calls were made, Bluetooth disconnected (I do have a 256 MB card installed, but I don't know if this has anything to do with it), furthermore the backlight is set to the default setting and the auto power off set to 1 min. In any case I would expect to get more than 40 mins use of the PDA, the specification states upto 15 hours.
I took the unit back to the store, they say that this is a rare problem (yeah right :roll: ), they gave me a new battery which I am now recharging, hopefully this will work.
mmmm, it's very strange.
I am doing a test now. I have a imate with the official imate upgrade. I have a gps sysonchip bt. One and half hours ago i connected the imate with the gps and i started a demo of 500 km. Now the battery is at 75%.....Maybe de last upgrade solved this problem.... :shock:
You should get far better performance than this.
Three things that can drain the power:
Communications/Peripherals - IR, bluetooth, SDIO wireless LAN etc. Disable all of them unless you're actually using them.
Processor hungry programs - check if you have anything running in the background that could prevent the device switching to full sleep mode.
Lack of radio signal - if you're out of contact with a base station, the device tries to connect at full power every 30s - a big battery drain, so if you know you're out of contact, turn off the radio.
However, even with everything running, I'd expect a running time way above 40mins, so it sounds like you have a hardware problem with your device. I easily get 3h full brightness, full processing (ie watching a movie or playing a game) with radio on.
Turn IR off?
Is there anyway to actually turn the IR off on the XDA II?
Just the Start-Settings-Connections-Beam-Receive all incoming beams checkbox.
tried the new battery today, same procedure as yesterday (no bluetooth etc), had a slightly better performance today from the new battery, managed to get roughly an hours actual use out of the PDA (games etc) over a period of... 10 hours, ooh atleast it lasted the working day so must be better... however still no way near the 15 hours PDA work time as stated on the box!
However something I have noticed is that every now and then (after switching off the unit and just leaving it on the desk) the screen comes to life displaying a running program, (just how do you turn off the media player? I now realise it isnt with the "X"). Anyway why does it "power" back up? I wonder if this has anything to do with my power problem, that perhaps it has switched back on whilst in my pocket (BTW I have set the buttons so that they do not switch the PDA on accidently)
So, I'm recharging again, (I think I might take the MMC card out see if tht makes a difference). I expect something better for my EUR 500, what is the point of being able to go online anywhere if you have to be plugged into the mains! If I can't get the damn thing to work satisfactoraily by next week then it is going back to the shop, despite it being a Gucci shiny piece of kit!
@MoistVelvet: Actually, it;s not so much the device itself but the operating systems that is the cause of a few quirks. Luckily, a lot has been written on this forum and other forums on websites such as www.ppcw.net. A lot can been improved by limiting the number of programs that can be found in the \windows\startup folder of the XDA II. I'd suggest you have a look around in the various topics. I ended up honing my XDA II to a point where I am actually very very satisfied with it's performance ...
Can someone repost the items in the windows start up folder than can be deleted and what they do on the XDA II.
I was surprised at the amount of apps in there, but dont know what I can safely delete.
Steve
Wiz,
thanks for the tip, I'll have a look around.
Well the batery did last longer yesterday, managed to get through a whole workig day before it ran out, so the jury is still out!
Realised perhaps one of the reasons why the unit would switch itself on, whilst at work I have a very low signal, so every minute or two the signal strength would go up and switch the screen on. I have set to auto switch off after 1 min, but I wonder if there is there a way to stop it from switching on?
Hm, my experience is quite different. I use it throughout the day with around 15 phone calls, at least 2 GPRS synchronisations, some other usage of contacts, calendar and email and when I get home it's still around 60 percent - the most drain appears to happen on the way back home when I use the BT headset...
When your uses so much more power you may like to check what kind of programs you use. First idea is to have a critical look at fancy today plugins... my worst experience was with Battery Pack, the best way to empty your battery :lol:
Maybe you like to use UpTime plugin (http://ae.inc.ru/uptime_t.html) which really tells you how much you actually use the PocketPC and which doesn't do anythings while it's switched off...

Actually, the reason it periodically switches on is the O2 Homezone application. Whenever your phone changes to a new base station (which can happen even if you don't move), the stupid Homezone app turns the phone on. This is a known issue, and the only known remedy is to disable the app completely (remove from Autostart folder, soft reset phone).
Cheers

Hi
I have an xdaII, which i load loads and loads of things onto. I did find that the battery was draining quite quickly. eg. charge it all night, just leaving it running in the day with hardly any use would drain the battery by about 90 percent! Bluetooth was off etc.
One time, the thing drained completely, and it needed a hardboot. Im going to send it back shortly for investigation/repairs.
However, since it hardbooted, i have not installed a thing. And i am finding that the battery is lasting a lot longer. I managed to go 3 days, of average usage, (few incoming/outgoing calls), without charging the battery!
This makes me think some apps must cause the battery to drain. I had battery app installed (that runs in today screen). I had fonix voicedial installed. I had quite a few games installed.
I think some software was causing the battery consumption,.. possibly battery pack.
re
I have previously had problems with battery drain, due to apps running in the background.
I also found specific apps like the battery pack, LAN sdio, bluetooth and the camera app, would drain the battery quickly.
Although you can manage closing apps down through settings/system/memory/running programmes I found the app Gigatask http://gigatask.com/ a simpler way to manage tasks.
There are others, but I found this suitable for my needs.
Now when I close an app I know it's closed and not running in the background draining the battery.
I still charge daily, habit now when I get home from work, but I have no worries about battery drain, and it rarely goes lower than 65% for a normal days use.
Cheers, Shire
turning infrared beam recieve off will help a little

Using Pocket Bluetooth Tools

MAtes, I have a question regarding this nice tool. In the latest version it switches Bluetooth automatically off after 30 seconds of inactivity which causes some problems for me. On http://bluetooth.i-networx.de/index_e.html it says:
Bluetooth is switched on automatically on incoming calls. However it take some seconds until the connection to the headset/car kit is established. If you leave Bluetooth always on there is no delay.
Click to expand...

So how do I leave Bluetooth always on then?
Hello farnold,
Hey nice tool, I've never heard of it! Thanks for sharing the tip!
In return maybe I can help you with your problem....
In order to disable the 30 second timer you can either click on the white clock on the today screen (it must turn gray to show a disabled state) or simply disable that today item (Start/Settings/Today/Items and uncheck Bluetooth Tools) that way the power saving feature will not work, but the rest of the suite will...
I hope this resolves your problem.
Best regards,
Rayan
Thanks, mate, the trick was clicking on the clock symbol I used it today in "standard" mode where Bluetooth switches itself off after 30 seconds... still answer calls wasn't such a problem - just took a second longer I would say
I have downloaded and installed this program. I am impressed with the added abilities included in it - in particular the "step down the road" of voice dialing with a BT headset, in that the phone now actually responds to a button press from the headset, though voice-dialing is not yet possible.
I am however very concerned by the huge increase in battery drain - my i-mate drained from 100% to 0% overnight last night. Before installing this program it would rarely drain below 65% overnight. This was with the BT on all the time . . . but I always left BT on all of the time before as well. This issue would need to be addresses (obviously) before this program would be a viable option.
why dont your pda sleep in it's cradle ?
It could have last night . . . but I wnated to make sure everything was normal - I noticed a quicker power drain after installing it and wanted to do a longer test.
Also, I am about to travel to Ukraine for the next 10 days, and there will be long periods (like 9+ hour airplane ride) where charging will not be possible. A rapid drain of my MP3 player, eBook reader and game console (I love the i-mate! ) would make me a very unhappy traveller.
@BRosenow,
So why don't you use the Bluetooth 60 second auto power off instead?
That way you will save some juice and Bluetooth will still work when you get a call.
Regards,
Rayan
I installed this program and left my cradle around 15:00 today. It's now 21:15 and the battery displays 90% left. I have sent and received several SMS'es, so I don't feel that there are any extra drain on my system.
Regards
Michael
As I am now seeing, people in other forums are posting experiences similar to mine. See http://www.ppcsg.com/forums/viewtopic.php?t=32049&sid=b07cb63386a7323151a0a87d2b2e8081 for this discussion. They indicate (as I noticed when I had auto power-off enabled) that this had no effect of the quick power drain.
Strange, I am still at 86% power some 8 hours after leaving the charger. I have rebounded my GPS and used bluetooth briefly after installing the latest pocket bluetooth tools. Possible you have a conflict with some app I am not running..
Regards
Michael
Hm, really strange. I also did not see any change in power consumption using this tool. I always take mine off the cradle around 8am in the morning and use it throught the day until about 7pm in the evening. Bluetooth w/o that tool only in the car - now more or less always, but with Auto Sleep Mode... the power drain is about the same for me...
I have the same power drain problem. My device didn't power off automatically whichever profile (on the Today plugin) I used. It works only when I switch on the bluetooth timer, but I want to have it on always.
Mine, I got different issue... after installing this new version I'm having problem to connect to my Bluetooth headset sometimes it works sometime it doesn't. Also if it doesn't connect to my bluetooth headset I can't even use the phone itself, the other party can hear me but I can't hear the person on the other line. Also the Headset icon is missing when you're using BT headset. I installed it twice and end-up the same problem so I uninstall it and used the previous version.
BUT I really like the feature that you can dial the last number you call thru the BT Headset.
Anyone having the same problem? I am using the latest ROM of T-Mobile by the way!
Hey Superperry,
some problem this end non bt headset bubble when you are using the bluetooth headset.
When you make a call it does not connect automatically to the headset you have to press the button on the headset.
Sometime it connects sometimes it does not need more improvement in the latest version.
Regards
Gigi
After installing the new version i got the following problem.
When i am dialing using the phone itself with bluetooth off the
BT turns on and the bluelight is bliking and it turns off after 60sec.
This drains the battery quicker than before

Thanks for the input. Atleast now I know not only me having those problem.
And Yes, it still need some improvement on this latest version.
power drain and another weird problem
Yeah .... I've had the pwerdrain problem. Was fishing and even though I'd switched the device off, each time I checked it it had drastically lost juice. Was worried it was going to go completely flat before I got home. .... and I didn't make or receive a single call.
Also had another wierd problem - sometimes after switching unit off. it wouldn't switch on again until I did a soft reset.
Power drain..seems afflict me too,but I don't use any BtTools and take BT off..!
I charge my XDA2 twice a day..hmm..this lets me think that it is a application conflict!
Also seems my xda runs very slow..
and I have noticed when i connect my xda with active sync it sometimes doesnt sync but still waiting: Connecting (for ever) and uses 90% of my cpu,amazing!
Now will try to find the prob.
I also experienced power leak from my I-Mate. It ran out in half of the day even I was trying to charge it via USB. I had to uninstall app after loosing bunch of my business call this day
blue tooth toolkit causing serious problems (I think)
OK several days of using it, this is what I think is happening.
1. Without BTTK power drain on XDA2 very acceptable. With BT switched on permanently then drains about twice as quickly but still acceptable.
2. With BTTK installed and in BT timer mode, then drain is very good ie as per not having BT switched on at all. UNTIL Blue tooth is fist used for either an incoming or outgoing call. After that - even if it's theortically in the sleep mode - the drain is disastrous - lost 70% of the juice overnight with everything switched off.
3. If battery charge is below about 45 to 50% then powering off and on again by the on/off button doesn't work. After a power-off I have to do a soft reset.
...... of course mine might be a sepcial case, and BTTK might be interacting with something else, but it looks like I'll have to go the ROM upgrade route.

Bluetooth needs (very) much Energy

Hi,
I have a HTC HD2 and I was wondering why the Battery loses more than 25% over night. (100%) eight hours before.
Now I try some settings and I noticed that the cause is the bluetooth device.
It doesn't matter if it is visible or not. If it is turned on the device lost more than 25% energy within 8 hours.
If I turn bluetooth off, then it loses 5% within 8 hours which is ok for me. The 390h Standby has been measured with a clock which runs at least 5 times faster than normal clocks. Or the phone was turned off or without a SIM Card (and bluetooth was not active )
Does anybody noticed the same problems?
I have a Touch HD and a Touch Diamond 2 and both don't need so much energy and bluetooth is always on and discoverable.
Please don't try to get to far away from the topic in this discussion
I've noticed that seems to be contagious like a disease and at the end we talk about the greenhouse effect because I am to lazy to turn my bluetooth off when I don't need it...
Thank you for helping
And... Yes I've used the searchengine but with no satisfied results
Battery drain..
Actually my battery won't last a day!
During week i'm receiving a lot of mail (100+) on 4 accounts (exchanges server, hotmail and 2 accounts using imap) so I figured is was the mail..
but this weekend still noticed the battery drained very fast, and yes, my bluetooth is constantly enabled. I hate disableing it as I need it to automatically connect to my carkit.. but i'm gonna give it a shot.
Well... I am not alone with this problem.
But is that a problem with a driver or a hardware problem?
Maybe it could be fixed?!
Is there a way to NOT drain the battery and have a BT headset enabled all day?
I too am curious to know if having a BT headset always on, as the case for me with my HTC X-7501 as I need to answer calls while driving about.
My X-7501 will never last all day because (I am sure other factors pare at play) the BT is always on. Turn it off and the battery drain is lessened noticeably.
My concern is it will be the same with the HD2 (my future phone.
If anyone can shed some light on how to deal with this when one needs BT on most all the time, it would be greatly appreciated.
I cannot imagine trying to enable BT whenever a call comes in and doing so in time to answer the call.
Anyone have anything to suggest?
Thanks,
Claude H.
Yes. My HD2 with 1.66 rom, activating Bluetooth, to connect to BTheadset when needed, will deplete 30% within 7hrs....overnite with no other activity... *sad

Hi, is it possible for anyone of you with this problem to export registry? I would like to setup my phone to be discoverable even when phone is in standby. Apparently this is the situation with your phone and having a registry would definately help me.. thanks

Marshmallow wifi battery drain bug..

After installing marshmallow to note 4 910F, I found out to much battery consumption.. It was more obvius when i left phone at night, connected with my wifi router. It had 20-30% battery consumption at 7 hours. Phone on, wifi on, rest off.
If i turn off wifi, no battery drain.. I loose 3%.
Even with 4G on, and wifi off, i loose much less!!
I tried more than 4 roms 6.01, factory erased everything, even safe mode. Always wifi drain.
In lolipop i had about 3% drain with the same.
Searching in net, i found out same problems mostly with nexus (probably because they had first of all marshmallow and they find it first..). I also found the same for note 5.
Many say to set router to 2.4 gihahz, set static ip, turn off something like v6 ip protocol? I don't remember well.
Also i read, mostly problem exists if router have huawei chip.
Checked mine, and it did had huawei chip..
Anyway i didn't found a solution for this. Tried better battery stats and found out tha alarms was for long time. Sleep was 85%, when normal would be 97%.
I also have a photo showing bigger drain in wifi than 4G.
Anyway how problem solved? I changed router and with everything same, i loose 3%....
But when i connect to other routers coffe, etc, if they have the same chip i still have drain there.
I probably find out the problem in note 4 first of all, as i dont read anything searching so, i inform others here.
note marshmellow battery drain
hope this helps. had the same problem of battery drain and not being able to put phone in power saving mode. i stumbled upon things that the update cuts on and you have no idea, anyway, it seems that the update has the search for other devices running 24/7 and you have to go in and switch it off. since then power mode has been enabled and stays on and battery life is back.
hello , guys .. beezyb can you explain with steps ?! you said that it seems that the update has the search for other devices running 24 hours / 7 days and i have to go in and switch it off ... bla bla .. what you mean with that ? !! can you help me ? !

Battery meter goes crazy since update (YB1-X90F_170420)

Does anyone have the same issue and knows what to do?
Since the update it
a) drains while not in use (depletes the battery jn 5 days without use approximately)
b) Rapidly goes from 90% to 60, suddenly drops to 30
c) Suddenly goes back uo to 60%
It seems as if the battery meter has gone absolutely crazy...
Should I contact Lenovo Support or is this a known bug that has a workaround or solution?
I can not confirm this.
But in my case I have done a hard reset. Maybe its also an option for you?
I don't have the erratic meter issue, but mine *does* drain the battery during sleep. The WiFi stays on, even though I have it set to "never".
I haven't noticed this problem. Various devices in my past have seen similar issues following an update before. A factory reset should resolve it, unless your battery has a physical problem.
First couple of days after the update I felt like my battery was draining faster, but that belief was corrected with use. Thankfully.
You can turn off WiFi scanning. This will shut down WiFi properly.
The one I have must be a freck I fully charge it and get 4 days of regular use........
Did you update to 170519? Maybe the problem is solved then.
