how long should my iPhone6 battery last

This generic 'no one knows' response does not address the simple generic 'give me the expected life of my battery with normal use' question.

I am using an iPhone 6 purchased new in May 2015. I recently updated the iOS to the newest version 9. I have NOT added any new applications and my usage of the device has NOT changed dramatically. Those facts stated" I now have a battery that is depleting and a speed so fast I need to recharge it 2-3 times durning my work day.

I in fact also reset all the setting to off. Nothing is doing now what it did before the recent operating system update. I shut off all the location and background running features. Yet my battery now depletes so fast I can use it as a fan to cool a room. So you see this kind of 'no one knows kind of silly' is not helpful at all!

I contacted 'apple help and created a specific ticket' to address the issue. My phone was diagnosed using two battery specific diagnose tools from Apple. The phone is reporting to them as being healthy and running as designed. That means that this is NOT a hardware issue.

I reset the phone back to new. I did that only after backing up the iPhone to my iMac desktop computer to prevent having to re-install all the functions and apps. This step was aggressive beyond my mind. Over the next 4 hours I started adding things to the phone that I use daily. I had to in fact look up passwords to re-activate applications to function as needed. I had to also re-autohorzie those website contacts to enable the phone to work as I use daily. (thank goodness it was a Saturday and not a work day)! It took four hours to reset everything. During that time I ran things like I do daily and normal. The battery life depleted to 40 percent in that 4 hour window.

Historically before the update of the newest iOS version I was able to use the iPhone all day long without everything shut off. I still had 40 percent battery life by the end of my typical 10 hour work day. Hmmmm? Seems like something is amiss here?

So back to my original question: HOW LONG SHOULD AN IPHONE 6 using the the most current operating system be expected to work?

A. 3 hours

B. 4 hours

C. 5 hours

D. None of the above but:_______?

E. You need to go buy another new iPhone with a brand new battery.

My sarcasm here is that anyone can say it is not possible to determine this truth ever!

Between 30 minutes to 240 hours, depending on your usage.

Nobody here can answer that. It depends on usage, and what hardware settings you have.

Go to Settings -> Battery and find out what's using the most power.

You're very welcome. I have a "6" with 9.2.1.

In your investigation, don't rely on the battery level indicator. Measure operating time from full charge (overnight) to automatic shut-down (ignore any alerts that may appear). Also, be sure to use Apple's charger and cable.

While this can be done at any time, it’s not a bad idea to do the following: Make a backup. Import your photos. Restore the device as new through iTunes. This is to ensure that there is no user data or bad iOS installation causing issues

• First, charge up the device to 100%. To enable the percentage indicator, go to Settings > General > Usage, and turn on Battery Percentage.

• Once the device is charged to 100%, make sure to close out all Apps that are running on the device. In iOS 7+, you close out running apps by double-tapping the Home Button, and then swiping your finger up across the preview screen of each app to move it off the top of the screen.

• Then, turn off Wi-Fi, Bluetooth and cellular data. Settings > Wi-Fi > Wi-Fi: OFF, Settings > Bluetooth > Bluetooth: OFF, & Settings > Cellular > Cellular Data: OFF. This will not prevent you from receiving any phone calls.

• Go back to the Home Screen, and take a screenshot. Press both the Sleep/Wake button and the Home button together briefly, and you will see the screen flash white for a split-second, and an image will be saved to your Photo App Camera Roll.

• Disconnect the iPhone from the charger, and lock the screen so it is dark.

• Let the iPhone sit in this ‘standby state’ for as long as possible, preferably overnight.

• In the morning, unlock the screen, and then take a screenshot of the Home Screen again.

These two screenshots will help to document how long the device was in standby mode, and how much battery percentage was used. If less than 2% is used per hour (i.e., after 8 hours the device is at about 85%), then it is extremely unlikely that there is an issue with the hardware. If a battery issue persists, even after properly restoring as new and performing this test correctly, the device (or charging accessories) may have a hardware issue. This is not intended to replace the diagnostics test available through Apple. But it is useful in helping to isolate a issue more accurately.

I get six hours but, as you've already been told, it's related to usage.

Aslo, there is no detectable difference between now and with previous IOS levels.

Hey, that's good news.

Happy Valentine's Day!
