Yesterday at night, my phone had about 86% battery left when I went to sleep. Today I wake up and I go to press the lock button to try to wake my phone up and it doesn't turn on. I thought it had shut itself off like many G2x are known to do, so I did a battery pull and tried to turn it on. It still wouldn't turn on.
I connected the battery charger to my phone and turned it on that way. When it turned on, the battery icon was empty and it was showing a "?" mark inside of it.
It stayed like that for about 5 minutes, then the battery started charging again, but it said it had 1% left.
What could have caused this?
The only app that was running was Juice Defender and it's setup to turn off wifi and all data connection from 12am to 8am.

Were you in a bad signal area? I noticed considerable drain before in the basement. Had to do with signals, was constantly searching for a better/stronger signal.
Are you using a ROM? Are you rooted if not? If rooted download a battery calibration app, charge to 100%, use the app, unplug phone and use till dead. Batterystats.ini may have bogus values in it and that's showing false info. That process should correct it.
I use cm7 nightly 151 with faux's oc/uv 0.4.2 kernel and sometimes I get the battery icon with ? in it, corrects itself once it detects properly.

That's most likely why. In places where I get 1 bar my battery tends to die very fast even with the screen off. So I pop it in airplane mode when I'm sleeping or know I'll be busy for a while.

No need if you have wifi available. just turn on wifi calling and you wont notice much of a battery drain with a bad signal, so people will still be able to contact you via call or text

+1 on this,
This happened to me on 2 phones, my friend have over 40% and he found dead, after 15mins in his pocket, same with mine, I thought my phone locked up, tried to reset and pull battery, didn't not help, found out 0% when lug in charge. Most of the times, after flashing a new rom, battery showing choppy stats.

Anyone else get 50% time without signal in Cell Standby under Battery use? I've always had reception and no problems. Cell standby sits at 10% and I've had no battery problems. Im guessing this 50% is garbage, since the time its been unplugged is wrong. 50% of the time is wrong, and 50% of the time without signal is wrong I guess... would this be safe to assume?

I have this problem every time I reboot the phone. It's resolved by putting the phone in airplane mode and then turning off airplane mode. I usually notice my battery life is worse when this happens.
Usually the time unplugged for me is double what it's supposed to be when time without signal is 50%.

Right. Happened to me a couple times when on some custom ROMs. Rebooting generally resolves this issue.
I know this has been discussed in the Gummycharge thread, but its buried pretty deep.
I know kej said that it has to do with the gallery, but I have uninstalled the Gallery3D.apk using the toolbox and I still seem to be losing about 10% per hour with the phone sitting idle on my desk.
Is there something we can use to quantify the appropriate battery drain rate? We all use our phones differently, so we need a way to standardize the battery drain so we can discuss it.
I saw someone mentioned that they were only losing 2% per hour while idle.
Currently, If i unplug the phone, and leave it sit for an hour (after a full charge) with only wifi on (gps, and bluetooth off) I lose about 10% per hour. If i use the phone at all, for example, When i wake up in the morning after a full charge and read the latest XDA posts, or some news articles, I can go from 100% to 85% in about 20 min.
this doesnt seem right.
Can we consolidate the battery drain issue to this post and post fixes and discuss reasons here?
This should have been posted in General first off.
Also, do you have SpareParts installed? If so, use that to check if your phone is entering sleep mode. You may have an app that is preventing your phone from sleeping, which will cause excessive battery drain like you are experiencing. My battery drain is <<1%/hr in airplane mode (I lose 1-2% over 8-9hrs in airplane mode) and when not in airplane mode, I'd say I loose at most 2-3%/hr if the phone is only sitting idle and I'm not using it.

I get a drain of about 3-4% an hour if mine sits. However I leave it on LTE and at the office there is no LTE service yet. Yeah I'm just lazy......lol.
Curious on your SpareParts thing tho. I've never used it much really. Where does it show/display whether or not it is going into sleep mode. now I'm kinda curiosu if mine is correctly or not. Not that I'm very concerned about 4% and hr as I make it threw a full day fine. TIA

If it's not running, it's sleeping. You're battery drain is likely caused by wifi being one 100%. If you are leaving the cell radio on, LTE, and also wifi, that is 3 radios on all at once, draining power.

is that just an issue with the charge? with my Incredible, leaving wifi on saved battery as it did not need to talk to the cell tower and try to get a 3g signal. Also, Before I flashed, I was able to sit all day in school and still be at %80ish power.
I will see what turning wifi off does.. but to be perfectly honest. that seems a little inefficient, that would mean every time i turn on the phone to use it, i would have to turn on wifi and sync, then turn it back off again.
For example, since I wrote this post, my battery has gone from 87% to 70%. 17% in 66 min even with wifi on, that cant be "normal drain". And All i have done is looked at 2 text messages.
Please do not get me wrong, I am not complaining at all. but I would like to get to the bottom of this.
I was on my way to the store to return the charge I hated it so much, but after flashing gummy and your kernel, I love the thing more than any phone ive ever had. So please do not mis-judge my intentions here. I simply want to know if this is normal. In my experience with sell phones (Droid Incredible for over a year, Wife has htc thunderbolt, and now the charge both stock and now custom rom) It is draining much much faster than any phone I have used before.
If this is normal, then I will just deal with it.
I am going to put it in airplane mode for the next hour and see what happens
It is def something in connectivity. Still at 75% after 1 hour in airplane mode. going go turn on 3g only and check again in 30 min.
I was going through battery stats and saw that wifi ON was at 100% and Wifi running was also at 100%..
seems like maybe somethign is using my data. so if that is true, it should try while on 3g and I should get huge battery drain.
will report back
Dude you are NOT alone. my phone drains like a siv, when its nt even being used. I always have LTE off, unless i tether wifi and I always plug it in when i tether so i dont drain. Itll just sit and be idle with NO use and lose 30%. i have gps, wifi and bluetooth off..... wth? this phone is looking ro get returned if i cant sort it out. i cant sit on a charger all the time.
If you are running Gummy, the gallery thing should not be an issue anymore (he fixed it a few versions ago).
When you go into spare parts, go to battery history and change to sensor usage. That will tell you immediately if you have some app that is draining your battery (ie the Gallery).
For the most part the battery killer for people is network searching. 3G,4G and WiFi are all in the same boat in that they will kill your battery if your phone has to constantly scan for them. To my knowledge using WiFi is better on power than 3/4G, but that is only if you are connected to a good signal and your phone doesn't have to search.
Also, I have noticed that the WiFi antenna on my charge isn't all that good, so you may want to keep an eye on it during your day. You may find that it is losing WiFi and scanning without you realizing.
The LTE radio in the Charge can be a huge hog. Especially if your in an area that likes to switch between 4G and 3G. Both my work and my home switch between 3G and 4G a lot and its not uncommon to see my phone drain almost 10% in an hour. On a good day it will be 5% an hour with LTE enabled. With mobile data and wifi off it can go down 0-2% per hour.
As far as I know, this is most likely just a sign of the Charge's battery. I'm not sure what Engadget was smoking in their review, but my Charge gets pretty horrendous battery life, especially in areas with dodgy signal (think constant switching between 3G and 4G). This is the first phone I've bought extra cables for charging in the car and office, but honestly, with these things getting as crazy as they are, I think this might be the norm in the future, what with battery technology lagging behind so much.
Some tips I've learned: turn the Wi-Fi radio off when not in use, and if you're in a really low-coverage area, consider even turning data off (you'll still be able to receive calls).
I live in NY, which is absolutely blanketed by 4g. I get better 4g reception than 3g in some places. I am getting horrific battery life. I just wiped, then mounted each partition individually and wiped and then reinstalled gummy 1.8.5 and per imnuts' recommendation, not install the reboot options. I had a custom rom on this phone within an hour of purchasing this phone, so I can't compare stock to a custom rom's battery life. I just know over the few days I've had this phone, my battery has been terrible. I shudder to think what the Thunderbolt must be like.
Your battery may be draining fast the first boot. Just reboot it. If that doesn't work then it didnt flash properly. Just reflash everything and remember to clear data, cache... hope it helps.
You can download an overclocking app and reduce battery use IF you already solved the battery drain problem.

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.

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.
I've always been reasonably happy with my battery life. If I use it heavily it goes down. If I don't it can stay charged for a couple of days. Within the last week or so that has dramatically changed. All of a sudden it barely makes it through the night from a full charge to 10% or so. It also "seems" that normal use drains it at least twice as fast. Anecdotal but I know something is wrong or different.
I haven't made any changes to my phone for months. I'm running existz kernal for 2.2 and that is the only customization. I did get a bunch of app updates but that always happens. The battery use screen shows the batter is being used for display but over night, it doesn't/shouldn't display much.
Thoughts on how to find what the heck is going on would be appreciated.

What I would do if I were you is charge to 100%, recalibrate, and take the battery out for about 15 minutes before you put it back in and turn your phone on. I dunno.why this procedure worked for me but that's just a suggestion if you don't wanna flash to stock and back to whatever you're using.
Uninstall updates, then add them back, one at a time.

I notice dramatically different battery life when I use this procedure to charge my phone known as a bump charge.
1) charge to 100% or as close as your phone will get while it is on.
2) Disconnect charger
3)Turn off phone
4)Re-Connect charger while phone is off
5) Wait until the phone says 100% charged while it is off. You can check the charge by using the volume buttons if the screen is asleep.
6) Unplug charger. (This is important. If you boot your phone with your charger plugged in it can give you inaccurate battery information.)
7) Boot up the phone.
That is really odd but mine has started doing the exact same thing. I have never had battery issues and for the first time today my phone was completely dead within 6 hours, and the past week it seems to hardly make it 12 hours.
I was just assuming it was the launcher I was using but I removed it and it never helped whatsoever.

I'll give that a try... it made it through last night in pretty good shape though. Confused I am.
Not sure if this helps or not, but here is my experience.
I have two wireless routers in my house. One I keep locked to N-only and the other to G-Only. The N router I have suspected for some time has a weak or flaky radio because I can watch the signal strength fluctuate wildly over a period of 10 seconds or so. I noticed a while back that when my phone is connected to the N router it will kill itself pretty much overnight. When I disable that connection and let it connect to the G router it only loses a couple % over an 8 hour period.
I don't know if it is due to being connected to N, or if my suspected flaky router is causing it to use more power staying locked onto the signal or something of that sort.
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

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..
Sent from my Nexus 5 using Tapatalk
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.

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:
