Haywire battery usage over night - Xperia Z3 Q&A, Help & Troubleshooting

Hey guys. I always restart my phone before I go to bed, and I never charge it overnight. I just charge it the 1,5 hrs I have before I leave the house in the morning.
Usually this works fine, but this morning the phone was very hot. Very very hot. I've never held a so hot handset before. I had to hold down power and volume to even get it on.
It went from 60-ish to 27% overnight and as you can see from the screenshot, there's a hole in the graph, with no apps apparently being logged as consumers overnight.
Anyone got any ideas about this?

might want to do a full charge and see if problem persists. meaning 0-100%

1. Clear all app in task manager. Restart phone sometimes.
2. To force phone shutdown, press both Power button + Volume up button at same time.

screen not shutting off.

I've had my phone less than a week. Since I got it the screen has shut off after not being used for 2 minutes pretty consistantly till yesterday, and battery life was ok. Now, its just staying on all the time(dims after a few seconds idle, but doesn't go out). And my battery has been draining very fast, like full charge at 9am to dead at noon after a half hour call and a few texts. I can't figure out whats doing it. It is still set to shut off after 2 minutes when not on charger.

Mine shuts off except when on charger even tho I have it set to go off after a min. I just put it to sleep by touching the power button. I do this to save battery and avoid an unwanted press as I'm a pocket guy. Does yours go off with a press of the power button?
yes when i push the power button it still shuts off

Strange battery

The last couple of days I've noticed something strange with my battery. I keep it on the charger all night and when I get up in the morning my phone says the battery is at 100% and the charge LED is green. The instant I pull my phone off the charger it drops a couple percent. I thought that was strange so this morning instead of pulling the phone off I just shut it down. Once the phone was completely off the LED went from Green to Orange as if it was charging again. It look another 20 minutes to turn green again. I powered the phone up and as soon as sense is loaded I am back to 93% battery.
Anyone else see this? I've wiped battery stats and did the whole calibration but that didn't seem to fix the issue.
That is normal... Once the batt hits 100%, the charger goes off and lets it drop to 95% or so and starts charging again. It does this to protect the battery. Also when you turn off, it will restart the charge.
The battery is lying, but that's not such a bad thing.

My battery has been acting up the last few days as well. As in, going from a full charge to ~35% in 3 hours and then down to ~12% an hour later. No new apps added, nothing out of the ordinary done. Regular uses and charging cycle. I normally reset my battery stats when I flash a new incarnation of a new ROM, but after a couple of days everything seems to be back to normal.
I've been baffled by this, but have yet to find the culprit. An app or searching for signal are my only thoughts.

[Q] Airplane mode vs. Power down

On a four hour flight this past weekend, I shut my stock 1.12.605.6 ThunderBolt off completely by holding the power button, then selecting "Power off". The battery level was at 68% at the time. When I landed and booted back up, my battery was at 17%. That's a 51% drop over a four hour period with the phone powered off.
To test it further, on the way back, I set the phone to airplane mode. The battery was at 71%. At the end of the four hour flight, I powered up the screen to see that the battery was at 68%. That's a 3% drop over a four hour period with the phone powered on, but all the radios (and the screen) off.
Has anyone experienced this?
That is strange. Have you reset the battery stats?

That's weird. Turning on/restarting your phone drains some battery, but not that much... I'd just leave my phone on airplane mode...

You need to clear battery stats or condition you battery with bump charges....when I first got my phone I charged it to 100% then unplugged it and immediately rebooted and it dropped to 78%. The batts are just weird imo

It didn't actually drop that much. It wasn't reporting the battery % right. Either before or after the reboot.

Battery question. Dieing when powered off

Ok I have searched and not found anything like this yet so I am going to ask. I know the phone has battery problems all around for a lot of people. Mine seems to be fine when it is on. It can sit and idle powered on all day locked and stay at full charge. It runs about 10 hours with minimal use and maybe 8 hours with some data use and a few calls and texts. Now I am experiencing a wired problem. When I go to work we cannot have cell phones. I leave my phone in my locker and power it off. After my 12 hour shift is up at work I come back to the phone with a dead battery? What could be causing this? And has anyone else noticed this issue?
defective battery? pull the battery and see if it still does it. If it does, gotta be a defective battery.. if it doesn't do it when pulled, you're not shutting off the phone maybe?
Yesterday I tried leaving the battery out. I took the battery out and let it sit 12 hours and it still had full charge when I put it back in. When I go to work I long press on the power/lock button and choose Power off then I watch it shut down and it just dies before I come back. I wish I could watch it the whole time. Today I left the phone off for around 6 hours and came back and it was fine though. Maybe it gets turned on some how at work. I have no idea. Or when I go to power it on it is just the issue where the phone isn't reading battery % correctly and it just says 0%
Seems like a battery driver issue or a defective battery? definitely call t-mobile and check if it's the battery. I've had some issues as well, but not that bad.
Weird.
So the phone powers off after you turn the screen on and it won't come back on? Try putting the phone in airplane mode.
Also, I'm assuming you are running the stock roms?
Might also want to check into a battery monitor to see if any 1 thing is pulling it down.
I think it might just be the battery driver. Sounds like the phone is in suspend so it doesn't power off properly until the screen is turned on and is revived, updating the battery % status, seeing 0%, and turning off.
CM7 fixed the wonky battery issue a few nights ago. Right now, I think a current CM based rom is the best bet as it has most of the drivers fixed. I'ved used mine pretty heavily today, unplugged at 8am and I just got a 15% battery warning at 11:30pm. It will usually last until I go to bed at midnight but I might want to play with it some more.

Question Power off/Battery drops

I charge my phone to 90% or 80% each night, power off, and go to sleep. The next morning when I power on the battery has dropped 2%. I would appear the phone is doing something when the power is allegedly turned off.
What's happening? Is there actually a way to turn if OFF?
just put it to airplane mode and compare it.
Okay. First I'll do A/M with power on. Battery drops just like at night. I'll do A/M with power off tonight.
and why u not charging overnight
Uh, I don't won't to. It isn't required. I charge it to either 80% or 90%, power off, and go to bed. Why would I want to charge it all night? Last night I put it in airplane mode, charged it to 90%, power off, and went to bed. I turned it on this morning and it was at 88%. I'm just curious what it's doing overnight when it's in airplane mode and supposedly powered off. I don't know that it matters but I've had the phone since August 16th and I got it new.
than get use to it
I'm just curious. I contacted Sony Support today but since my issue isn't really a problem they didn't have much to offer. They were very courteous, though.
2% is "NOTHING" for an overnight drain. Please note that power off/on also consumes considerable power as it puts a load on the processor as it has to unload/load all the processes during that. My Sony phone loses 5% on an average per night and that is completely acceptable as it constantly works in the background (some apps keep refreshing every now and then, I also have poor network reception so that's also a consideration). I'd say: don't sweat too much and your phone's just fine!
On a side note, I also have a Samsung S22 Ultra that has an average 13-15% drain overnight.

Thanks. I wasn't worried as much as curious. Since I don't do games, music videos, or Facebook my battery isn't a worry. Just a curiosity. If I lost 15% in a night with power off I'd wonder if my phone was moonlighting as an Uber driver.
