[Q] [I9001] Temperature problem

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.

[Q] Samsung Galaxy Note critical battery life after 4.1.2 update

Hello!
I know that there were a lot said about battery problems in 4.1.2 android, but i still haven't found any solution on my problem. My Note was bought with GB 2.3.6 and had an awesome battery, but after i updated it to JB 4.1.2 (via Kies), suddenly battery life is catastrophic. I have everything off (bluetooth, wi-fi, gps), my screen brightness is on minimum, i use my phone on GSM band (not 4g), i also disabled some of unused apps, etc...everything said was also my practice on previous version 2.3.6 and phone battery lasts up to 4 days, but now, it drains off in 17hrs and I barely use my phone!
If I check battery stats, it shows that screen is the major consumer of battery and it seems like it is on all the time, although the phone screen is physically off most of the time. It means something causing my phone being awake all the time instead of being off.
Any ideas how to fix this??

4 days? really? think that is unheard of. Either how, it should last longer than 17 hours.
Try going back to factory settings, perhaps theres something running thats divided by zero :silly: .
If you feel adventurous you can also choose to root & try a custom rom. Though thats your responsibility and choice entirely.

Yup 4 days, not kiddin...4 days of average use.
I forgot to mention that i already did the factory reset and i also wipe the cache partition in recovery menu... I disabled practically everything, and i use things when i need, nothing is set on auto, sync or anything. Last night I didn't touch the phone for about 9 hrs and battery consumption was around 1% which is ok, but it's draining everytime i turn on the screen like 5% in 10mins. BBS shows that well known GTALK_ASYNC_CONN as a battery eater. Is it possible to kill this annoying thing on un-rooted phone???

[Q] Galaxy Gear and batery performance.

Well, i don't have a gear yet but i have this question about the performance of the batery at cellphone side.
I keep my bluetooth always off to make my batery works longer, but with gear i belive it will need to be always on.
How this works to the cell? the conection is aways alive draining the power or maybe it will be activated by the gear when i will use it?
And another fast question. I Have a Galaxy Beam who is like a s2. I have some hope to use the gear with this device by cfw or it is and will be aways useles for these 1.2ghz middle age cellphones?

In most cases you will require android 4.3 or above, which you phone doesn't support. I would recommend upgrading your phine before wasting money on a support gadget.

I use the Jelly Bean rom, my phone is rooted. there´s a way then?

The gear utilizes Bluetooth 4.0ble which stands for Bluetooth low energy. You don't need to shut Bluetooth down to save battery anymore. Pairing a 4.0 to a 3.0 will pair. But the 3.0 hardware will drain faster.
As long as you're on a 4.3 or higher rom you'll be able to use most features, but not all. Follow the thread "gear on my nexus 5" for installation details. It's in the general section.

Thanks, i will follow it. The only reason for me to keep my beam is the projector. Really waiting for a new release of this phone.

I see no difference in battery with bluetooth on all day! I am using the latest version 4.4.2, but with the 4.3 did not notice anything too!

Bluetooth battery drain

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.

Galaxy Tab 2 T519 WiFi and battery problems

Hi,
I have 2 problems with my Galaxy Tab 2 which I hope I could somehow fix with a FW adjustment.
As with many others, the WiFi on my Samsung Galaxy Tab S2 no longer works properly and can no longer be switched on when the tablet is switched off and on again. If the tablet runs out because the battery has run out (0% battery), WiFi will work again after the restart.
In addition, the battery is drained very quickly. I even bought and installed a new battery for this. But I have the same problem there. Overnight, the battery tends to lose about 50% of its capacity even though the tablet is lying around in idle.
That is why I can only use the tablet when it is plugged in because the battery is constantly empty and I cannot switch it off because otherwise the WiFi will no longer work.
A hardware defect would behave differently, wouldn't it?
I tried:
Downloaded the last available FW version of the tablet from Samfirm.
I then correctly loaded the FW onto the tablet using Odin, Download Mode, etc. Unfortunately, it did not fix the problem and I still cannot activate the WLAN and the problems remain.
Edit. It's a SM T819. Sorry for the wrong title.
