IPHONE 6 (battery usage)

[M_GO_BLUE1]

My wife got a new IPhone 6 less than 2 months ago and has been fine...

Within the past 3-5 days the battery will last all day and then some (as it always has) but then when we go to bed at night by morning the battery is completely dead...nothing has been downloaded on the phone in the last 2 weeks...about 99% of the time the phone is on home wifi...

According to the Verizon rep she said it was due to the screen brightness being too high and it is continuing to search for wifi even if it is on wifi...according to the phones battery usage it says the "home & lock screen" has taken up 39% of battery usage in the last 24 hours...I say the battery sucks

Any advice, thoughts, suggestions on the above?

My Galaxy Note 4 has no problems with the battery usage...frustrating

The other thing it could be is wherever your phone is resting at night has weak cell reception. When this happens the phone goes into high power for its polling activities trying to call home to the local site. I left my phone on in a flight bag from LA to Dallas once, and a freshly charged battery was dead in a tad over 2 hours.

(edit: spellin' errors on a Galaxy Note4)

During the day the phone is for the most part normal but it is at night when it really discharges...

As an example this morning over night the phone had discharged down to 23% from 66% EVEN WITH WIFI AND CELLULAR DATA TURNED OFF...

I will have to check the GPS on the apps to see if that will help...

Unfortunately that GPS icon is now useless as any app thats recently used it will now flag the icon whether its currently in use or not. The only way to tell is go in and look at all the apps for past use with the above link, and even that isnt dead accurate. But at least it narrows down the list of culprits.

Yes a reboot is different tan just turning off the phone. As explained to me turning off the phone it "remembers " some settings. A reboot kills all operations and restarts the phone and loads back the os fresh
Like others My bet is you have some rogue app that's not letting go and still using gps ( do you see the gps symbol at the top of the screen? ) or something similar

Plug the phone in at night the battery has 500 full cycle 100% to 0 charges in it ... Going from 100 to 50 then charging to 100 is 1/2 a cycle . Leaving it plugged in it uses no cycles and the drain overnight comes from the charger not the battery

Simply closing apps or resetting the phone does not shut down notifications. I have probably 20 various notification services running: weather, news alerts, earthquake notifications, eBAY, etc., and the phone is never shut off. I have services muted over night and it turns itself back On in the morning. The phone gets charged overnight and will easily last the following day with all this running as long as I don't start using WAZE or some other traffic app. BUT, and as mentioned earlier here, there are some apps that are a little sloppy about shutting down the GPS when they are done.

Go to Settings> Privacy> Location Services, and shut down any app that you think has no reason to know where you are, and there are lots of them. FYI- I used to have Beat the Traffic to watch my morning commute, but it would never let go of the GPS, even when it was forced closed, kept killing the battery, so I finally deleted it.

BTW- when in Location Services, look at each app and see how it accesses the GPS and when. You have the option of Never, Always, and (rarely) Only when in Operation. Some are just nosey so shut them off. At the bottom of the page are System Services with a bunch of various things like location specific ad placement. IMO- kill that and a few others. Every little bit helps

I never turn wifi off. No wifi at home. About once a month I kill apps. I never plug phone in overnight. Battery goes down 2% max at night.

I have 30 apps open right now. But I also have them so they only find my location while using app. Maybe that's your problem.

We clear the apps all the time...and no good smartphone should be continually searching for wifi when you are connected to wifi which in our case is Comcast internet

A reboot is when you hold the on/off button and the home button down at the same time until the Apple logo appears.

Not the same as just turning it off.

As stated, push home button twice and close all the apps. If you leave any apps that use GPS eg Google Maps, Maps, Urban Spoon, etc it will chew up battery.

If you leave wifi on where there is no wifi it will keep searching for a signal.

Google iphone power management to learn how to change settings.

Plug it in at night like everyone else.

Go to settings. Check wifi the phone is using. I have same issue at work, I have to disregard all other wifi's other than the one I use. It will automatically search for wifi until they are turned off. It continues to search and will eat up battery life

22 Tips to Extend iPhone Battery Life

I have a iPhone 6Plus. I actually abuse the battery life, LOL. I do everything opposite on the list. I do charge my phone at night and during the day if I'm home.

[Desert_Captain]

I have had my new 6 Plus for several months and (love it), simply turn it off at night. I usually only have to charge it about once or twice a week. Turning off the apps you are not using is a good idea and only takes a second. I don't make/get many calls but use the phone extensively everyday surfing the net, e mails etc.. i think the exceptional battery life is one of the many benefits of this amazing phone.

Yes, I have suggestions. Nine times out of ten, the reason for this behavior is that she has left every app on the phone running. Running apps eat up power, just how it is.

Here's what she should do. After logging in (she does have a password set, right?) press the home button twice. The screen will then show all running apps, and if you flick a given app upward, it will quit. You will find that everything you've ever run on the iPhone is still running, and the first time you do this, the list will be long. Quit everything that you don't need running overnight. Quit mail, and maps, and calculator, quit all that junk, and your battery will not get sucked dry overnight.

Chances are that there is only one or two apps that are responsible for this behavior. With some experimentation, you can figure out what the culprits are, and then you can use them when you need them and immediately quit them after you are done to save battery.

Lots of people blame the battery when this inevitably happens.
