I have recently upgraded to 5.1 OTA release on a 100% is, always has been, stock phone. When running 4.4 I had no problems connecting and running a low energy Bluetooth connection to a heart rate monitor. Now I'm having significant issues of singal dropping off in and reading being way off. Anyone else having similar issues. Fix? Or am I stuck with a useless heart rate monitor now

Hello everyone!
I noticed a temperature problem while my phone is idle or in use.
After A LOT of tests, I discovered the cause: the radio!
If I have wifi and/or 3g active, after some time the phone become very hot on the back near the camera.
The battery is perfectly cold (even if the radio is draing it like hell: 90% -> 69% in only 1 hour!) so I excluded it.
I have a Galaxy S+ (9001) with CM10a7 by ivendor.
I originally had radio XXKPF and a really bad wifi-stuck problem, so I upgraded to XXKPO. Wifi problem got less frequent, but the heat become more frequent than XXKPF.
I recently (yesterday) tried the BUKP7, but I changed it soon because the phone became so hot that it stop reponding. I'm now with the XXKPM and the problem is slightly less frequent.
For those of you that are using CM10 ivendor and similar roms, what radio is the best?
I'm from Italy if needed.
Thanks :fingers-crossed:
I'm using the XXKPO and everything is ok..

Thanks.
I confirm that XXKPM make my phone hot less frequent than the KPO and BUKP7, but battery drain remains too high
Only thing I can do is a complete wipe/data factory and reinstall the rom from scratch.
Hi! I recently adquired the O4x and have been using it with my sony smartwatch 2 on bluetooth.
However i have noticed that the bluetooth on this device drains the battery much more than on my previous device, the Samsung S2 LTE.
If I connect the smartwatch in the morning i usualy get like 60% of battery left by lunch whereas on the S2 LTE I would still have around 80%...
I have tried disabling the bluetooth visability but battery usage remains the same.
Also, i'm on rooted stock 4.0.3 rigth now. Do you think I should upgrade to 4.1.2 ? I´m asking because I read that the O4x gets very laggy and with low RAM after update... I dont want to flash any roms yet...
Thanks

AFAIK it will only get better if you upgrade to 4.3 or further, because there's Low Energy Bluetooth that uses considerably less battery (as I've read, I don't own any Bluetooth component to try it).
A little over a week ago I became the happy owner of a 2016 Volkswagen Golf GTI. I used my Galaxy S7 Edge with the Android Auto for the first week. After a bit of a tricky time getting it paired it worked great! No disconnects, no phone issues, and it operated very smooth!
A couple days ago I switched back to using my Nexus 6P. I noticed yesterday the phone got VERY hot after using it with Android Auto for about 40 minutes. I figured since it was a hot day and with my interior being black, then it was mostly just heat the phone absorbed from inside the hot car. Today it was much cooler only 82 degrees, and I blasted AC on about medium the entiretime, and after about 30 minutes when I went to unplug the phone it was EXTREMELY hot again. It had to be at least 130-135 degrees F on the back cover. Because it was hot to the point of stinging my hand, but not enough to burn. Like a silver metal poll thats been in the sun for hours. About that kind of hot.
This was very shocking because as we all know the Nexus 6P has the coolest running 810 processor of any phone. I have never had it get hot before in many months of use. Only warm. I know it can't be a Android Auto problem since it doesn't happen to my S7 with the 820 processor. It seems that Android Auto is the final kryptonite for the 810 processor of the 6P. My M9 with the 810 got hot like this when playing intesive games while it charged. But nothing like that withthe 810 processor in tge 6P before. Is anyone else experiencing over heating issues with their phone? If so, what phone and what processor?
I have a 2016 Optima SX Technology and have the same issue. There appears to be confounding issues, but my understanding is that this particular problem is Galaxy S6 ATT latest update. My issues in no particular order
The phone drops my GMAIL auto sync each time I remove it from an Android Auto session. Perhaps stops autosync upon opening but can't tell since we have no phone access during session
Phone will not charge during AA session, a Kia issue because they only provide 100 mA at the USB connect port. One needs to use a different port for proper charging. Kia is aware, will not do anything yet. Curious to know if other automakes don't provide sufficient current to charge during session
AA is a great driving assist, but with these hassles in the latest configs Gal S6, Android 6.0.1 Knox 2.6 2500 mA battery, Optima '16 SX Tech, the functionality if very limited to short hops. No one wants to arrive at work with a dead phone...............
Foll-up Resolved
Please accept this follow up to my issue and possibly others running the latest OTA updatd of the Android OS.
A separate post on this great site mentioned that after every OTA update, it is best practise to backup and perform a full factory reset.
So I decided to backup on Samsung SmartSwitch, rather simple took ~10 min. The full rest was performed off the settings menu.
When it was done, I provided my WIFI router password, restored my phone's app's settings, etc. and Now I have a cool running phone, that both charges over my Kia Optima low current port and also runs Android Auto without either an overheating problem or gmail sync issue. I will keep monitoring it. But as of now, I am a full believer in the power of a factory reset after a forced OTA update.

Glad to hear yours resolved so far. Mine charges great with my Nexus 6p and Volkswagen. Still getting the over heating some but it seems it's not as severe now. Still continues some but will keep monitoring.
I have a Nexus 5 (patch level May 2016) and it is getting far too hot when using Android Auto. It's getting so hot that I doubt that it will run without damage for many hours.
This occurs especially when I am using the navigation. However Android Auto without navigation makes not too much sense.
I am going to install the july OTA Update during th enext days, however I don't expect nay change.
I'm having an issue with my Galaxy Tab S2 (Nougat 7.0, international unlocked T710 Snapdragon) when using any bluetooth device with it. The battery drains like hell. After a two or three hours of using a bluetooth keyboard, bluetooth is the main cultprit of battery usage. I don't know what to do - I wiped the cache partition, did a factory reset. Nothing helped.
Otherwise, the battery life is great, but as soon as I connect it with a BT device I can see it dropping. Everytime I click on Bluetooth in Battery settings I can see there's more mAh used...
I would appreciate any help.
Nougat.. thus better downgrade to MM or Lollipop.
Dear all,
I Have same bug with My SMT-813 since update Nougat, When I use with skeaper bluetooth.
Do you have found a solution?
Did you factory reset after OS update?

Dear,
Yes, all reset.
I think it's Nougat because with android 6.01 all is ok.
So better downgrade back to 6.0.1 then.

Yes, it's happening since the Nougat update. I've already filed a bug report for it but got no answer from Samsung till today.
The only thing you can do about it is to turn it off. And if you need it you have to downgrade to MM.
Same here on t819, but its kind of fake data, in my opinion there is somrthing wrong in calculating mah consumption. My battery still lasts the same, even when using or not using bt, but it has a lot of bugs, like forgetting paired devices or failing to pair. Everything about bluetooth is not perfect on N
Hi All
Do you have news about this bug?
Workaround
I've had the same battery drain issue on my S2 since upgrading to Nougat. Yesterday however I found I could 'fool' the system by turning on Flight Mode and then turning BT and WiFi back on - Consumption back to normal! It looks weird having Flight Mode on at the same time as BT & WiFi but it seems to work.
Update
I’ve just been trying to repeat my observations and the results are a little ‘challenging’
I saw a comment in another forum where someone suggested that the discharge effect is really a false positive caused by a faulty battery monitor in the Samsung software. So a downloaded a third party battery monitor, I charged my tablet to 100% , turned off flight mode and turned on both WiFi and Bluetooth.
The main observation is that the battery was not discharging rapidly – previously you could virtually watch the percentage on the battery meter decreasing in real time. After using the tablet for a day or so for browsing and watching some short videos I compared the two battery monitors – the Samsung monitor showed the battery down to 40% - but ascribed virtually all of the use to Bluetooth! The third party monitor showed a sensible mix: mostly browser and video player with small values for other programs.
I conclude therefore that the Samsung battery meter is definitely very broken.
As far as my earlier observed battery drain is concerned there seem to be two possibilities:
1) It was truly the Bluetooth causing the drain and switching to flight mode has cleared it (unlikely in my view)
2) The drain was caused by something else but was displayed by the battery meter as Bluetooth, and when I switched to Flight Mode it stopped - either by coincidence or because the Flight Mode really stopped the drain.
Number 2 seems to me the most likely explanation. I have noticed that all of my Android devices exhibit anomalous battery drain about once a month, and a functioning battery meter shows this as Android System usage. I don’t know what it is doing but my best guess it is some sort of file scan/verification (or maybe just harvesting data!). After a system upgrade it would be quite plausible that Android wants to scan the new installation.
I have, in the past, stopped this Android process by rebooting a device, so it is not impossible that entering Flight mode has had a similar effect.
For the moment my S2 seems to be using a sensible amount of power – both with and without Flight Mode - albeit with useless reporting of the details by the Samsung monitor.
Hello, I got my phone fixed the mic, then I reinstalled the android Lollipop 5.0 rooted build, since then I don't know if the phone is having software or hardware issues, signal strength is under normal compared with another s5 (I believe is a radio issue), battery drains in 4 or less hours, the screens can be hot when using it or even in stand by, and some times the phone resets itself when I put the phone on table a bit hard, what should I do, I don't remember having those issues before fixing the mic.
Thank for help
