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.

What's the deal with my battery?

So often, before I go to bed, I would charge up the phone completely and turn it off. 8 hours later, I turn it on, and the battery is at 70~80 ish.
Yesterday however, I just put the phone on airplane mode without turning it off, thinking it might make a difference. I woke up and the battery was 99%.
WTF?

Because when you turn on airplane mode, you turn off radio, wifi, etc about signal and data. It is about 50-70% power consumption. Consequently, when data is cut off, apps that needs to update via data, either wifi or mobile, won't update. That is another less stress on the battery. So on and so forth.

Well that's weird cause I put my phone on sleep last night without airplane mode and with 3g on, and it went from 90% to 87% by 7am. Maybe it has to do with low signal? I know when I have low signal my battery drops SUPER fast.

You totally failed to understand my problem. I'm saying airplane mode with phone ON consumes LESS battery than turning the phone completely OFF

I completely misunderstood your problem. Hmmm, in THAT case only thing I can think of is the phone not being shutdown properly. Aka the phone got stuck in a low level state with the screen off/unresponsive but maybe the phone was still processing network information. Then when you turned it on, you shut it off and turned it back on without really noticing.
That, or the FBI has been tracking you in the night.

We still didn't answer his question! Its weird that the battery is getting drained with the phone completely off.

How about telling us also what rom/kernel you are using?
Sent from my Calculator with Android.

I had an issue with my phone charging, it would take about 18 hours to charge the battery completely. Turned out the cord had gotten screwed up somehow. Also if you're using a USB extention cable, if you use more than one it will do something similar.

Charge your phone, turn it off, remove the battery and check if it still looses power.. so we will know if it s a battery problem or phone drainage problem

1. rom/kernel: cm 7.1.0.1, default cm7 kernel
2. update: second night with this Rom, and when i turned it off and on again 8 hrs later, it was 91%. Not bad.
3. I have charged full> powered down> removed battery> 8hrs later> insert battery & power ON, battery is full.
4. Computer USB charging takes probably over twice as long compared to using the outlet adapter.
I understand that phone goes into a low power state when it is turned "OFF", but really, what gives?

I have a feeling that the phone is not shutting off all the way. How about trying to shut down your phone, pull the battery, reinsert it, but DON'T turn your phone on and don't touch the power button at all, just reinsert it. Wait 8 hours, check it then.

Powered Off / Battery Drain COMPLETE

I have now had this problem twice this week. I have read other posts that sound similar but the issue seems different.
Twice I have shut down my phone at night. With FULL battery. The next morning, I could not turn the phone on. It would vibrate when I hit power button but not come on at all.
Both times I plugged it in and saw that the battery was COMPLETELY drained. I have seen threads where people post about some battery drain overnight, but this was an entire drain, with the phone off.
This is a major issue obviously as both times the next morning I was on the go and had zero battery life.
Any ideas of what this can be? Does it sound like a physical battery issue? Is the phone maybe not actually shutting down and getting caught in some battery draining process?
Help please.

The best way to test the shutdown issue is pulling the battery after it seems to shut down. Try pulling it for a few seconds and replacing it, but leaving the device off. If that produces the same result, try leaving the battery out overnight.

This seems to only be happening if I leave the battery in the phone.
It happened again last night. Complete drain.
Im not sure but I feel like there may have been a buzz as it turned itself off (not sure if its always there need to experiment further). I picked it up and hit buttons to make sure it wasnt just in standby. It wasnt. it was OFF.
Next morning, no battery.
Any ideas? Id love some help as this is becoming a pretty big problem for me.

Have you ruled out a hardware issue already? If not then call the carrier.

This actually happened to me a night before last as well - twas the first night running Smooth Ice 5.1. Are you on that by chance? Not knowledgeable enough to really comment on whether or not that could be it, but it'd be something to eliminate.
I switched to the new leak last night and the battery life has been excellent off charger all day, for what it's worth.

I am on stock everything.
I am still trying to diagnose the problem.
It seems that when I Power Off, occasionally at the end of the power done I will get a Vibrate. When that happens, I think it is draining while switched off.
When the Power Down happens and I dont feel the vibrate, so far I have not experienced the drain.
Does that perhaps give anyone ideas about what might be happening? Some kind of locked in Process or App? Any likely culprits? Any diagnostics that can show, if it does drain, what drained it?
In the past when it drained I plugged it in to charge and checked battery stats, but it showed Display as the largest consumer. Does the About Battery stats reset each time you plug in and start charging?

It always vibrates when you power off, at least mine does.
The battery stats reset after a full charge has been achieved.
I have no idea what would be discharging it while off besides a bad battery.

Put the BetterBatteryStats application on there. The stock Battery Use GUI interface that is built into the firmware will not show you details enough, it will just show what application used the cpu for X amount and caused the battery to go down X amount.
Put BetterBatteryStats on there to find out what is causing the phone to get drained so quickly. Seems like its not going in deep sleep mode and there is some partial wakelock that is keeping the phone from going into deep sleep. That app will tell you what service or application is holding the largest wakelocks and amount of time it does it for. This helps to determine the issue. Without this, you are just speculating on the problem with the built in Battery Use stats/graph in the Status screen.

Something else I noticed...
Over the last few data, sometimes when I power down the phone, it goes through the powering down process usual, but as soon as its done, the phone vibrates and powers right back on...
Anyone experience this or an idea why that would happen?

Just a thought; If I'm charging my phone with a generic charger (500 mA) and shut it off, it will reboot.
If I'm charging with either the factory wall charger or a 12 volt that triggers AC charge it won't.

The reboot happens when I shut down and am not plugged in to a charger at all....

My galaxy S has been doing this too lately (loses all charge when off overnight). It always buzzes on shutdown.
One thing that mine has is a problem with the usb port, it slowly stopped working and now I can't charge it anymore through the port. I'm wondering if there is a physical short there that is causing the battery to drain. Possibly you have something similar going on, or a short elsewhere in the system.
I've noticed that you cannot shut the phone down when charging from certain chargers too, especially in the car. Very annoying.

Bump
Hey guys,
Im still having this issue and wanted to hear if there is a known fix or solution?

Honestly, the severity of battery drain you're describing sounds lije more of a hardware issue than anything else. I would contact yoir carrier as mentioned above. Beyond that, trying out a custom ics like sky or embryo might be your best bet if you prefer the tw interface. Im on embryo 5.1 right now and am experiencing better battery health and longevity than ever before with the skyrocket. But the issue does sound like a bad battery.

Same exact issue, but I have the t-mobile version.

This happened to me on one of my i777s.
The phone would even not boot up. It will just vibrate. Turns out the battery was bad. Changed the battery. It was still the same.
Then tried another charger, same thing happened.
So then I changed the whole charging port part in the phone.
Voila! Phone worked like a charm.
So if you have warranty change the phone. If not change the charging port. At least in my case.
I came to a conclusion that even the battery went bad because of the bad charging. Might be a coincidence too.

I have 3 S2 phones that I bought as defect and played around with. Two I could fix but I could not resolve the battery issue on the third phone like by buying a brandnew USB charger part (and trying the ones from the other 2 phones. It has nothing to do with the ROM or anything software either. I narrowed it down to be an issue on the actual mainboard. The weird thing is that the battery discharges way faster when the phone is turned off than when it's in use.

Phone keeps shutting down unless plugged in

Hi guys. I have a weird problem with my htc one x that started recently. I got it about a year ago but from like last week, it keeps on shutting down (not restarting) and then I have to wait a bit before I turn it back on. This is because if I turn it back on straightaway it starts to overheat and then turns off. When I manage to turn it back on it shuts down after a bit of usage. The only way it works properly is when it's connected to a charger which basically means its unusable. I'm thinking that maybe I just need to change the battery but since it will take some time and effort, I wanna get some opinions and be sure. Thanks in advance. The phone is on official stock and I've tried factory reset.

The fact that it doesnt overheat and shut down when plugged in leads me to believe its not the battery since the battery gets even hotter when plugged in. Also, since you are able to turn it back on, that means theres still a charge.

It does get extremely hot when it's plugged in and sometimes turns off but that's only when I'm using it for web browsing or something. If I'm not using it when it's plugged in that much then it's ok. And whenever I turn it on it keeps giving different battery readings. Sometimes it will say 80%. Then if I restart it it will say 30%. And sometimes it will have an exclamation mark where it's meant to say the battery reading :/

Hmm well you can certainly change the battery then. Have you taken this phone apart before? Be gentle or you could end up breaking the screen and also, you have to take the whole thing apart to change the battery wince the battery connects on the underside of the mainboard

Slight battery drain when phone switched off

Hi all
I usually charge my Nexus 5 before i go to bed and last thing i do is check i have a full white block then unplug it ready for next day. Usually when i wake up and turn the phone on its at 99%. However this morning i turned it on and it was at 94%, now i agree its not a massive loss but is there anything that could drain the battery when its switched off?
thanks for any help
Chris

Hello,
Yes, there could be plenty of reasons for the battery drain like bad signal, gps turned on, apps waking your device and so on...
If you are rooted, please post the screenshots of BBS and wakelock detector..

I think you are over thinking it. Rebooting the phone can create some ups and downs on the battery level.
The battery level is computed, it's not a 100% accurate gauge, that's why sometimes after reboots some people see increases in battery level or you can see a 94-90% last more than it lasted on another day.
"Geeks" take things too seriously

Just don't turn it off, i only get 3% loss overnight with it on anyway

Apps waking your device when it turned off? didnt realise that was possible!
i am not rooted! (always think it will go wrong)
thanks for all the answers i think maybe i am looking too much into it all....one thing i did do differently this time was as soon as it got to the full white block signal i unplugged it, where as normally i leave it on a while longer at full charge.

I think you're just looking into it too much. Whenever you turn on your phone, it won't necessarily report the exact same % as when it turns off. Also, turning on your phone uses a lot of CPU, so that might be contributing a little tiny bit to why it's a little bit lower.

You most likely unplugged your phone before it was fully charged. It says 100% but it continues charging for 20-30 minutes, albeit slowly.

Turning your phone off and on when it's unplugged consumes battery power, probably moreso than letting it idle.

This is also true. Rebooting uses power, current widget will even show large spikes for minutes afterwards. That mixed with not "over charging" it would account for this.

Thanks all....

I have also noticed once the same thing. I don't think turning off the phone and starting it again will take away 6% battery but rather I think the battery stats were probably wrong and showed 100% charge while the true measurement was around 94%.
I think it is done intentionally so that the battery doesn't degrade easily in future.
As said above leave the phone for charging for more than 30 min after 100%, you will see increase in battery life dunno how it affects the battery cycles in future.

Usually until and unless you cut the data connection off before your turn off your Nexus few of your apps reboots automatically which eats up the battery a little . I hope this helps.:good:
