Instant battery drain (to 0%) on AT&T One X

So odd. Are you battery drain victims in LTE areas when this happens?
 
Evening, all --

I've had this same problem with both the original HTC One X I got two weeks ago, and then again with the replacement for it this past week. Sounds like exactly the same deal: it's fine for days in a row, then I've got plenty of battery power when I go to sleep one particular night, and I wake up the next morning to find it won't even turn on; I've got to plug it in to get it to power up.

Called my carrier and they admitted they can't know everything about every phone or what impact third-party apps may have on them, and the suggestion was process of elimination: take away a few apps at a time and give it 48-72 hours to see if the problem occurs again. I'm just in the midst of testing the first round of deletions.

I'm curious: have people with this problem noticed it happening on a particular night of the week? Or after a certain number of days of being turned on, etc? Because it was the third or fourth night after I first got it that the first total drain happened, and then the fourth night after I got the replacement that it happened again. Tuesday night will be the next fourth night of it running... be interesting to see if it happens again then.

I agree with what's been said before: I don't think it can be a hardware issue or anything fundamental/stock, because then it would affect everyone who has this make and model. That it's a particular app, or a clashing of more than one of them, that's causing the battery to plummet seems the most reasonable approach. The LTE being somehow to blame is an interesting possibility. Be interesting to hear from folks who've had this problem if going wifi overnight still experience the issue.

Icebike pointed out that no one's made an exhaustive list of their apps. I'm quite willing to be the first to do that if others with this problem will join in to see if there are any common items among our lists.
Anyone?

Also, Icebike: you clearly have some clue what you're talking about, so can you please clarify: is putting a phone (any phone, HTC One X or otherwise) on wifi more efficient on the battery than using the data signal? Because with my previous phone, the Samsung Captivate S, I accidentally left it on wifi overnight and found the battery really suffered for it compared to when I had it on the data signal alone.
Which didn't make much sense to me: how is feeding from a router 30 feet from my phone more draining than getting signals from towers miles away?
Yet my wife, who has an iPhone (with enviable battery efficiency, incidentally) has it on wifi pretty constantly -- I think it defaults to link to the home signal when it can -- and her battery usage is amazing compared to mine (even with this new phone), but that's a bit apples-to-oranges.
So bottom line: wifi better or worse than data signal for battery use? And if it's better, are we talking the wifi on WITH the data signal on, or the data signal shut off completely in favor of wifi whenever possible?

Thanks!
 
Its been my experience that wifi is a significant battery savings over 3G, unless you are at the max wifi range.

With an lte phone, this is even more so.
The days that I get 24-28 hours run time are days that I spend most of the day on wifi at the office and at home.

Wifi, in my experience, left on overnight does not affect battery life much at all. Like 1-2% drained overnight.
 
So to recap: the fourth night after I got my replacement phone, I had the same sudden, total battery drain I experienced once with the first phone. I uninstalled some apps this past Saturday to see if any of them were perhaps rogue and doing something unexpected to the battery, so it's now been four full days since they were uninstalled, and so far, no repeat of the total battery drain.

In case others who've experienced the total battery drain are interested, these are the apps I uninstalled:
Yelp
Toddler Lock
Solitaire
Parent Dashboard
Kid Coloring

You may want to give a shot at deleting any of those you may have and see if it makes a difference for your own total battery drain issue. I'll keep you posted if it happens to me again.

The only other real change I made (a couple of days after uninstalling the above) was installing Nova Launcher, but that was primarily due to watching an HTC One X video whose host said that she calculated less battery drainage with Nova in place than without it... back to the usual issue of trying to conserve battery power day-to-day.
 
I just moved and had a few days without internet/wifi at my new home. My One X had a hard time keeping the battery charged when on LTE-only. It probably didn't help that I had 2 bars at the house instead of the full signal I'm used to, either. Before the move, I could leave the phone on overnight and lose maybe 10% of my battery. After moving, it was completely drained overnight from 70% when I forgot to put it on the charger.

My own anecdotal experience is that the LTE radio is draining your battery much faster than wifi will. If you have wifi, be sure to use it.
 
I'll give it a shot tonight. Last night I hit a new low (/high): 20% battery drain over about 6 hours of sitting idle on my nightstand. Those were the kind of numbers with my Samsung that ultimately led to my getting a new phone in the first place a couple of weeks back.

Still seems weird to me that there's such a huge variation in battery drain overnight. With the same apps installed, I've had as little as 4% overnight and as much as -- well, aside from the lone total battery drain problem -- 20%. Same apps, same phone, same location in the house for the same amount of time... odd that drainage swings that wildly.

Anyway, thanks, I'll try switiching to wifi tonight and see how it goes.
 
Icebike and SmorgasBorgnine -- I tried wifi overnight. 20% drop the previous night on LTE, and upwards of 30% drop last night on wifi. And that was allegedly with full bars.

Bear in mind, that's unusual... 20% (well, now over 30%) is the worst drop in the week I've had the phone. It's been as little as I think 4% (maybe 6%?) prior to two nights ago, and except for the one total power drop.

But check this out: more odd still is that I plugged it in when I woke up this morning (at around 65% battery power, as I recall), and checked it 10 minutes later for something else. That was when I noticed that, after being plugged in, the battery power had DROPPED to 38%. Even if it weren't plugged in, if I didn't get the connection quite completely so it wasn't actually charging, how does it drop almost 20% in 10 minutes?

I'd call my carrier about it, but I'm sure they'd again tell me it isn't a hardware issue (because it isn't happening all the time), so much be a software issue, so delete the apps and start from scratch, monitoring each app as I go. Looks like I may have to do just that.
 
I think you definitely have a software issue, because that much drop over night is just not normal.

Are you running a task killer? If so, uninstall it. Task killers can cause more drain, and are never needed since android 2.1.

Good to know that seems to be the right approach. I know I've got too many apps -- I'm a parent of a toddler so there's a lot of "just in case" entertainment apps -- so probably a good idea to trim down anyway.

The only task killer on there is the one that came stock on it. I haven't used it since getting this replacement phone. Not wholly sure I can uninstall it (any more than any other stock apps) because it's not rooted, but no, it's not something I use.
 
Incidentally, have you tried the app called Carat? Apparently it pinpoints what apps are battery drainers and suggests courses of action for them. Hadn't heard about it until yesterday.

... and of course, the possible irony of it being the battery drainer for the last 16 hours isn't lost on me...
 
I use carot for a long time. After I found all the culprits I un installed it. Battery monitors use battery.

Its far more likely to be some social app that's draining the battery than a kid's game. Kill Facebook. And similar apps as well.

(there is life after Facebook ;-)

Yeah, that was going to be my approach, as well: use Carat to find problem apps, then kill it. No reason to have it with no problems, after all.

And yeah, I think Facebook may be to blame. That one I'll uninstall, since it's far more robust just going to the full website anyway. Some flavor of Twitter app, though, you'll have to pry from my cold, dead hands... :)
 
My HTC One X replacement drained off when it had only skype and whatsapp installed in addition to the AT&T bloatware. For the second drain I had compass app installed. My data was off during both drains. But wifi was on during one of the drains.
 
Hoping it's not WhatsApp, because it's really handy for keeping me in touch with friends and family around the world.

But, guess I'll do whatever I need to do...
 
No, it's not installed, but thanks for the heads up.
I've been doing a bit of reading around, and social media apps are definitely the most frequently earmarked as being bad battery drains, so I'll kill Facebook and see how that goes. If Plume (an installed Twitter client with a great UI) turns out to be an issue, too, I'll also kill it and try to find a decent Twitter app that isn't as big a battery drain, but hoping that's not the case...
