MASSIVE iPhone 5 battery drain while in standby
 

Mrs. OTW58 recently started a new job and was given an iPhone 5 as her business line.

No issues to speak of until the last day or so, but the battery is draining ridiculously quick.

Took it off the charger this morning around 9:00 at 100% - then turned off LTE, Wifi, closed all open apps, turned down the screen brightness and turned off location services for everything but Maps and Weather.

The phone hasn't been used at all today. Nothing.

Now 5 hours later, the battery is at 33%

WTF?

This is the problem we have had with iPod Touch for the last few years. Never figured it out. Been a problem since iOS 4 really.

thats how my ipod touch was, sometimes batteries just fail.

Weird.

First issue I've ever had with an Apple product. I have a 6+ year old MacBook that has only needed a battery, (which Apple paid for, even out of warranty) numerous iPhones and an iPad2.

Never a problem.

Just looked, it's down to 28% now.

turning wifi off helped mine but don't know what to tell you on yours. Did she upgrade to iOS6 this week? Also, did you push and hold home to make sure nothing else was running in the background/

Download the app "Carat". It will take a week to collect data but it tracks the processes on your phone and lets you know which apps are sucking up your battery. It also compares your phone's battery to all the phone batteries it has data on and gives you a "J-Score" 1-100 on how well your phone battery works compared to others.

Great app, to say the least.

A quick reboot could likely solve the problem. Hold down the Power button for 10 seconds, until you see the Power Off slider. Power it off, then back on by holding the Power button again.

Usually this occurs when an app goes nuts or has a memory leak. If that doesn't fix it, I'd recommend a complete backup and restore from iTunes.

How's your LTE signal? If its marginal, then the phone is likely trying really hard to maintain the connection.

I turned it off completely.

Damn near everything is off, and it still ran through the entire battery in 6 hours, without ANY use.

My iphone 5 runs for days without a charge. With everything enabled.

Yeah, it's gotta be a defective battery.

Apple doesn't make bad products bro, you must be doing something wrong.

Depending on connection, it is better to leave on wifi.. If not, it will be switching or lookign for a better signal.. Of course, even with all that.. Iphone is generally good on battery life, there might be something wrong.. Might want to take it in..

I've heard that restoring the device as a new phone can sometimes help with situations like this. PITA, but might be worth a shot.

Any new apps added shortly before the issue started? There have been problematic apps in the past.

This is basically how they'll treat you at the store.

I received a defective iPhone 5 and it took me forever to get it replaced. The thing wouldn't connect to the network to authenticate me.

Be sure all the iCloud shit is turned off. That can be a drain. But it really sounds like some app is going nuts. These issues are rarely the hardware.

First off, do a HARD reset on the phone and try the same experiment.


With the phone on, hold down the home button for a second, then while still holding the home button, hold down the power button as well for about 5-10 seconds, until the phone reboots to the apple logo and release. Now charge up your phone to 100%, and run the same experiment.

Also, did you actually SHUT DOWN all the apps running in the background?

To do this, double click the home button to make the recently used apps screen pop up at the bottom of the screen. Long press on one of these apps and they will all start shaking (just like moving apps around on the home screen), but in when they are in that pop up window, you can click the red X on them and all the apps that are "open" in the background will scroll. Close them all until that bottom screen is empty. (don't worry, you aren't actually deleting the apps like you would be on the main page, you're just shutting the apps down).


If, after you've done these simple things, your phone is still draining too quickly I'd start the complaining process and see if you can get it replaced. Especially if the phone is getting "hot" near the rear camera. Those things can go bad, and start heating up, consequently draining the battery very quickly. The batteries themselves rarely go bad. You might want to also check and see if your phone has any tripped liquid sensors...
