So I powered off my Nexus 7 last week before I went on vacation and found it completely dead when I tried to turn it on a week later - it would not even turn on. After charging for about 10 minutes it booted up but the battery was at 1% and charging. Initially i though I forgot to turn it off, but then again I was pretty sure I did. Once it charged up I powered it off completely ("Power Off" option after holding down the power button) and left it till 5PM the next day. Once it booted up it showed that I had only 44% charge, that's down from 100% just last night! WTF? It lasts me 3-4 days if it sleeps but looses 66% charge when powered off!? Anybody in the same boat?
It's the government tracking you. (Yes they can track a powered off device)

Cool! Thanks!
Also forgot to mention that my tablet was completely dead when I exchanged because of the touch screen issues with the previous one. The previous one turned on just fine! So maybe it was a bad batch, even though I hope it's not
I'm using GTab 8.9, but I experienced the same thing as the OP, too. I tried switching kernels and this issue went away.

I don't believe OP's story. Why would you go on vacation and leave your N7 at home? Your story doesn't add up.

I'm not starting a war here, but why would he lie? There's no reason for the OP to do so. (Except for increasing post count which I don't think so.)

Hey Guys,
I have been following this thread since a while and finally took the plunge with the S3.
it was a blue s3 and i loved it.
All stock, not rooted nothing..
So i was downloading my games and apps the first day all went well
the second night, i bought NOVA 3, and put it for charge while downloading the 1.7 gb data for the game over wifi.
i woke up in the morning and the phone is dead, it shows a yellow connect it to kies message.
I dont know what happened?
took it to the service center, they tried re-installing the firmware, but no avail. finally told me they have to replace the motherboard it was fried.
I fought with them and managed to get a replacement unit which im gonna get on monday.
The ordeal aside, i want to know, is it possible this happened because i downloaded too many games(6 actually)
each with about 400 mb data.
can a phone get bricked if i download nova 3's data of 1.6 gb
cause i am going to get all my games again.
so help with the solution!!
probably a 1 off defective unit.
You left it charging overnight right, have you considered a power surge may have fried it?
It's better to wake up early in the morning and put it on charge than to leave it overnight.
Sorry about your loss though.

I don't think the game's could do anything wrong to you while downloading.
Btw while playing games on SIII take care as the Phone's temperature reaches the sky and literally i have to close down the game because the phone becomes too hot.

power surge and over charge are totally different things. over charge protection would not prevent a power surge.
Most probably just a defective unit.
I left my HTC Sensation charging overnight once, and somehow there was an app running continuously and when I woke up the phone was scalding hot to touch. I freaked out and pulled the battery and let the whole thing cool before I booted it up again. Might not be relevant but just goes to show that our phones can take more heat than we think.

Charging overnight is safe

Hey guys,
I live in the uk and went to Bulgaria for 16 days. I left my S3 home and took an older phone with me. Didn't want my samsung stolen, etc.
So, before I left the house I charged the phone up and left it in airplane mode.
I got back more than 2 weeks later to find the phone still on in standby mode with 48% of battery left. Meaning that it could go for about 34 days in airplane mode with one charge.
I know we can't do much with this info but I felt the need to share it.
Sent from my GT-I9300 using xda app-developers app
That's awesome. My sgs2 can only make it for about a week in airplane mode, with a 2100mah extended battery.
Are you using the stock ROM? Looks like touchwiz icons from the screenshot you posted.

So in order to get great battery life all we need to do is never turn the screen on and never use it as an actual phone, great find!
I bought my s3 from cex (a popular exchange chain here in UK) and when I got the phone it was at 8% charge with 34 days of standby. The phone was left on, without sim card inserted, but with WiFi on, even if wasn't connected to any network. I thought it was pretty cool as the same happened with a one x I bought two weeks before, always from cex, and in the same condition the HTC was on 8 days standby time when it discharged completely in my hand

Nice!!!
Actually there is a point to this...
I think that this is a very interesting post. Why?
Because I suspect that for most people, there are times of the week when they don't actually use the phone or even need it available to take calls but (like me) don't want to have to turn it off at night and turn it on again in the morning.
So, using a tool like Llama, you can set your phone automatically to put itself into Airplane mode at night and to reconnect in the morning - so extending your stand-by time.
(Note: I actually go further than this - and put mobile data on only 3 minutes every 30 when screen is off. And I get great battery time - or would do if I didn't use the screen so much!!)

With every electronic gadget using Lithium-ion batteries nowadays, it doesn't really matter how/when you charge it.
Some would argue to make sure to allow a full discharge from a full charge from a battery calibration point of view, so the battery meter is more accurate. It wouldn't affect the health of the battery itself either way.
Things like memory effect doesn't apply to lithium-ion. How often you charge it and how much you charge it (full or partial charge etc.) doesn't affect it much either. The only 2 things that can potential kill a lithium-ion is high temperature and letting it discharge far too low to the point that it cannot be charged up again. Note that all electronic devices will power off way before it even reaches this threshold.

Read this in a different thread when i was unboxing my nexus 7, i let mine sit for a while on the charger before i turned it on, but it came charged already. So far i have not let my nexus drain to 0% and the battery life on it is great, it can go for a entire day.

Sounds like it may be a corrupt download. Unless you plan to remain on the stock ROM just unlock/root it and then install what ever ROM you like.

I'm praying that I don't have this problem AGAIN! My galaxy nexus had that "charging issue" where it would say its charging all the time. No chargers worked for it so I had to buy an external battery charger. On top of that the phone would wake itself up randomly. Destroying my battery time to 2-3 hours with light usage...
My nexus 4 isn't charging now. Literally just doesn't want to charge, tried 3 different USBs and nothing happens. I am going to murder someone if I go through this again. I don't wanna send mine back to Google or LG because I'm lucky enough to have gotten a "perfect" device, no yellowing, creaking, rattle. I can't take it anymore :banghead: has anyone experienced this?

Like someone said before it's a rogue app and the only way your going to get the battery drain issue to go away is to figure out which app is doing it and then get rid of it.

I think the best solution for you is to factory reset or re-install android on your device once.
It will be easier than finding out where is the problem. as screen snap shows most of the battery is drained by "android OS".
It was just my opinion you can take it if you want.
My battery usage. Even though my screen on time was only about 2 hrs most of the battery was drained by the screen. So there music be something very wrong in your case.
I don't know about android virus but that might be an option.

Gonna follow along and disable my daydream as well since I'm having the same problem you are with it actually draining while on the charger (Stock ROM, Franco Kernel, OEM wall wart with gold tipped USB cable). Tis quite annoying to have to either keep the screen off or power down completely in order for this bad boy to charge...
