Please help me with easy iPhone battery tests

Not sure how accurate user reported data will be for battery drain since the batteries age and become less efficient at holding a charge over time.

(That being said, I just replaced the battery in my iPhone 4S, so I'll let you know how it does).

Mercedes – that's very true. But we're looking for configurations that give unexpected egregious drain. For example, ATT iPhone5 lost 1% per hour, versus 1-2% per day for the ATT iPhone4. In one particularly bad configuration with ATT iPhone5 it was losing >5% per hour, and sadly that was exactly the configuration that worked best for the ATT iPhone4, so many people had a very bad experience when they upgraded from 4 to 5.

Amy I'll run the test tonight (iphone 6 AT&T).

Anecdotal, but on the recent Bob Open after running the phone ~ 17 hours/day for 3.5 days in airplane mode, Gaia in "on demand" gps mode and shutting it off at night- taking lots of pics, checking the map relatively frequently and occasionally engaging the gps feature, I still had 56% battery life when we made it to Swift Reservoir- I thought that was pretty decent

"For example, ATT iPhone5 lost 1% per hour, versus 1-2% per day for the ATT iPhone4."

Just to put that into perspective, a new high-quality lithium battery that is not hooked up to anything is supposed to have a self-drain of no more than 1-2% per month.

My att 6 in airplane mode in an area with no signal lost 0% over 12 hours. I took a couple of pictures and after 24 hours it was at 98%.

Amy- fully charged the battery (100%), at 7:30 PM put it in airplane mode and insured no gps apps were running, at 6:00 AM (10.5 hours) it was still at 100%, so less than a percent in 10.5 hours

iphone 6, AT&T

iPhone 4S on StraightTalk (AT&T's network), signal present
Running iOS 8.3

2% battery drain over 10 hours
6% battery drain over 10 hours in Farraday cage

Amy- looks like the first "test" wasn't a fluke, ran it again last night- full charge (100%) at 7:00 PM, at 6:00 AM still 100%, at 7:00 AM still 100%, at 7:30 AM 99%

again iphone 6, AT&T

Interim Report and Questions.

I have data from 2 ATT/iPhone6 users and 2 ATT/iPhone6-Plus users == all are consistent with 0-1% drain reported in a 9-11 hour countertop tests.

I have a lot of great data from one Verizon/iPhone6 user. She ran fourteen 9 to 11 hour tests and usually saw 2-3% drain, but it varied from 0-5%, with no discernable pattern about what factors mattered.

I'd like to hear from at least one (hopefully more) more Verizon user to see if it really is the case that Verizon/iPhone6 has more drain than the ATT/iPhone6

And I'd love to hear from some more iPhone5 users too, if possible.

And a question for Mercedes — in the test with no signal in which you lost 6%, can you confirm whether you had AirplaneMode ON for your two tests. That 6% loss in 10 hours is a disappointing value.

Thanks all, I appreciate it very much.

Amy,
100% at 9pm and 100% at 7 AM.
ATT IPhone 5s

Verizon iPhone 5
47% @ 9:41pm
43% @ 7:29am

Verizon iPhone 5 with SIM locked

2% drop (100%->98%) over a 25 hour period.

Thanks to all of you who helped test iphone battery drain. I incorporated all the data you kind folks contributed and made significant updates to the article. I appreciate the help you all provided.

I just returned from the JMT where I found that I could easily get 4 days of use of out of my Verizon iPhone 6 in Airplane mode using Gaia, Guthook's JMT app and maybe 20-40 photos a day.

Thread drift. I got 4 1/2 days out of ATT iPhone 6 in airport mode using some Gaia, punching Halfmile frequently; photos, Kindle and Spotify every day, and a total of 30 mins calls.
