Nexus 5 and Bluetooth - Nexus 5 Q&A, Help & Troubleshooting

It seems like all of a sudden my Nexus 5 has decided that whenever I have Bluetooth turned on that it is holding the device awake. Even when no devices are connected (connects to my car and a BT speaker).
I'm sure it didn’t used to do this.
I did a factory reset about 4 months ago.
Because of the hold awake battery life is down compared to normal.
Below are some screen shots for reference :

Then from GSAM:
You can see that BT sharing takes up a non-trivial amount of power. I'd like to get this thing back to normal.
Fully patched firmware, including today's Security patch.
I'm currently working around this by turning BT on only when I want to use it. That is a pain.

I'm seeing the same thing today... I could see my battery drop 10% in under an hour, with BT at the top of the battery list. Says my 60% remaining battery will last 3 hours

Any update on this? Having the same issue...

I don't think you're having any. When your screen is off, you're device is going to sleep (notice the power drain almost levels off when the screen is off). When the screen is on, your network signal isn't very good. If you were making calls, or sending text's (those don't use wifi) that kind of battery usage isn't terrible.
Both cases have around 9 hours of time unplugged, and it looks like the phone as the screen on and is being used for like 4-5 of them, maybe a bit less, and you're at around 40% battery? That doesn't seem abnormal. Battery testing for the One X shows about 10 hours of talk time, 5 hours of web browsing, 6 hours of video.

Galaxy Ace 3 S7275R battery drain

Hi! This is my first post on this forum, so first of all I want to excuse myself for my English.
This is my mothers phone. She had it since 2013, she likes it and never had experienced any problems up to few week ago. It is stock Android 4.2 no root. All modules are off, no bletooth, nfc, gps or wifi, and the only social apps installed, beside the stock ones, are WhatsApp, Viber and Skype.
A performed a calibration of the battery using the only one method that I know for no rotted phones - wait until the battery drops to 5%, and after that turn off the phone, taking out the battery for half an hour, and charge it for 5 hours without power it on.
This does not help at all, the drain persist. Those are the screenshots taken this morning:

Undead - No battery but works fine

Hi,
I replaced my Nexus's battery yesterday. Everything went well but trying to turn on my phone, it didn't lunch and but the led kept flashing in red. Reading here, I saw someone saying that it's a battery drain and to leave the phone charging for a couple of hours. Still nothing.
I tried to disconnect the battery from the board and start the phone and it worked. I then reconnected the battery (while the phone is lunching) and it's working but the battery percentage doesn't show and the red led is still flashing. See here (I know it small but look at the battery) -
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
.
I assume there's a problem with the board because I have two devices and I tried to switch the batteries between them and they work on the other device and red-led-flash on mine.
I'm using DU rom.
Anyone have any idea?
Thanks!

I had the same issue....try to reset app permission for the all the apps and see if it resolves.
In night actually i loose only 4%... same with all phone.... 2 % or 4 % maximum in flight mode !
Doesn't look like a widespread issue. Must be an app or maybe a syncing service. Check all apps. This is actually surprising because vivos OS likes to kill all apps

Battery suddenly lost it's capacity??

HI, I have a weird problem. So I have my a7 for about a week and a half now and you guys might know that if you open the battery monitoring thingy in the settings it should say that it's going to work for like 30 hours right? Well mine used to say so up untill like 2 days ago when it suddenly changed to ~19 hours when at 100% and the % go down real fast (for example, I used to go down ~20% with 8-15 school usage and now I go down 20% in 9-13 school usade). I am still on android 8.0 with the latest security patch. What in the actual frick is going on.
Here's an example screenshot of how much battery% go down in just 36minutes of mixed lte+ and wifi usage
