What Is "Normal" Battery Life on the iPhone 5 (5s)

I just upgraded to a 5s (64 GB) from a 4 (32 GB). :)

The big shocker is the battery life. :eek: What I'm having problems determining is what is "normal" for the iPhone 5 (particularly the 5s...if there's a difference). My research indicates that batter life was a complaint about the 5, and I've already done some research and turned off everything that wastes power (that I can live without).

Here is my typical routine with the 5s.

I get home about 6 pm. The 5s needs charging. I do it on the charge brick for my iPad2. As soon as I get home, I put the phone on Airplane Mode as I live outside of cell service and don't have WiFi. Once charged (100%), I disconnect power and the phone is little more than an alarm clock. Often go off to bed about 8:30 - 9:00 pm.

I wake up at 3:00 am most days. By this point the battery is already down to 70+% power. Under similar circumstances, my old 4 would still be in the 90+% range.

I have to do some things before I leave, so I plug in the 5s to get it back to 100%. When I leave, I turn off Airplane Mode.

By the end of my work day (5:00 pm), the 5s is down to 20-30% power. The phone sees little use beyond e-mail alerts and texting. I rarely place or receive calls. My old 4 would normally be 40-50% under the same circumstances.

Often, I could just omit charging the 4 when I got home and just plug it in at work the next day. I clearly can't do that with the 5s.

This weekend, I charged the 5s to 100% Friday night. Sunday morning, I'm under 20% with the phone sitting on a table in Airplane Mode. The old 4 would easily get through to Monday evening without needing to be charged. :eek:

Is this "normal" life expectancy on a full charge? I'd like to know how to identify unusual consumption on a device reputed to have issues with battery life.

Thanks. :cool:

Do you have apps running in the background? Also, if you set apps to try to update their content in the background and you put the phone on airplane mode said apps will try over and over and over again which drains battery life.

Apps have to be running in the background. Otherwise airplane mode would conserve battery.

If apps are running in the background the airplane mode will run your battery down faster

I have two apps I keep running in the background...My Data Manager and Battery Doctor. These should be left on all the time. I had "Background App Refresh" turned off, but I went into Settings, turned it on, and disabled it for everything...then turned it back off.

Battery Doctor says I have 25:50 of power remaining (at 100%).

Why does airplane mode drain battery with apps in the background?
Apps that require an internet connection to work properly will search over and over and over and over again until they find a connection. If Airplane mode is on, well, there is no connection. So the apps will keep searching, thus keeping the phone busy thus draining battery.

I was thinking the same thing. You'd think that if airplane mode was turned on that would kill all requests by an app to get data since none of the radios are on while airplane mode is active (unless you manually turn in wifi). That's how I'd figure it would work.

If in Airplane mode you phone will not even attempt to make a connection, much less over and over.

****! You get up at 3:00 am??
:D

Why does that surprise so many people? (lol)

I'd like to know the final word on "background app refresh" myself. I'd think apps would know to check and NOT waste time trying to update if the phone's in Airplane mode, but I kinda get it...they won't actually access the antenna, but they still try to check if the phone's free to communicate. I'd think every app that does this gives you the option to have it on or off, and as I pointed out, it's all turned off.
