Help Battery Draining Quickly/Phone Getting Hot

[Dankees]

I just got a new Galaxy Nexus yesterday, and the battery is just dying so fast, and phone is getting really hot. Why is that?

I turned off the 4G/LTE preferred setting. What else can I do?

The battery settings say that the screen is using 62% of my battery (and the screen has barely even been on).

Turn the brightness WAY DOWN. I would keep it no higher than 30%, I have mine at 10% which is plenty unless I'm out in the sun.

How much have you been using it? In the battery stats, click on "Screen" and see how long the screen has been on. Also, how many hours has the phone been unplugged at this point?

Your battery will drain a bit faster than usual since your phone is new.. give it a week or so (and a few full charges and discharges) for it to normalize. The more you use it of course, the faster the battery will die.

welcome to the nexus! This is one big complaint. Stick with it a while and you may see that it's still worth working around it by bringing a spare charged battery. There's also extended and super extended (3800?) batteries with special cases, but many aren't NFC enabled. I have to keep mine on the charger as often as I can. To me it's worth it at this time.

Well, I got it yesterday and I left it plugged in until this morning. However, I didn't realize that I didn't fully shut it down. So, that was dumb.

Anyway, now, I unplugged it this morning and it died within a matter of less than 4 hours, from a full charge.

I brought it down to 4%, then plugged it in and shut it off, fully. It was at 64% after about an hour and 15 minutes.

And, why the hell does it get so hot? What is that?

Auto-Brightness or do I want to just keep it on like 30%?

Can you post your battery stats? I don't know about the CDMA Nexus but my GSM Nexus can get 4 hours of just screen-on time, so your phone shouldn't be dying so fast if the screen is not on the whole time.

Nice try - that adds up to 102%

How much screen time in hours is that?

 

[Dankees]

I had the phone on from 9:48am to like 1:30pm, and it was nearly dead. And, I am at work, so I barely did anything with it. How is that possible?

 

[stenzor]

Can you post a screenshot of your history details (click the graph in the battery window, then hold volume down and power button to take a screenshot). Also click on the Screen from the battery window and paste a screenshot of that.

Exactly something is killing my bat.. updated a few apps and was searching the forums. The screen on time was 48 min I think. Can't remember exactly what it was.

If your screen was on the whole time, or most of the time, I would say it is normal, unfortunately. It's alot like a laptop in battery life, nothing like a flip phone.

It probably is but today was much faster than normal. I deleted a few apps gonna charge it up and try it again. See if I get the same results. In all honesty I don't mind the drain I'm constantly using my phone so I expect that to happen.

Need those screenshots to solve your problems.

I'm still not used to the phone, but I hit the volume down, held it, and pressed the power button, but nothing happened.

I figured out that it was slow to charge because I was charging via my computer's USB. My BlackBerry charged well this way, I guess this phone doesn't.

But, why would my screen usage be so high?

I just used the phone for about 12 minutes and the battery went from 100% to 94%. Is that normal? The phone is a day-old - I barely have anything running.

Then, I stopped using the phone, the screen went off, and the battery level went down 5% to 89% in 15 minutes, with no usage...?

You need to hold the volume down and power at the "exact " same time for 1-2 seconds.
What you describe sounds normal. Even though the screen is off, there is still a small amount of activity going on, unless you shut the phone down entirely.
You may have some settings or apps that are running that are hard on the battery, Idk. Unfortunately it does sound normal to me.

I shall try that screenshot thing.

On a side note, how come my phone (and my wife's phone) are grainy and have some vertical lines while in auto-brightness mode?

Could be a glare resistant screen protector

I got the screenshot. I add it with the paperclip icon. How do I actually upload it?

Well you could attach it or better, upload it to imgur: the simple image sharer and put the link you get from that (the one that ends in .jpg) in the box you get after clicking "insert image" (the little pictogram) above the box you type stuff in to post

 

[Dankees]

I do have a Zagg protector. That could do that?

Here is the screenshot (attached)...

Typical. My screen is 71% and OS 14%.
