Android vs iPhone boot times tested: which one is the fastest?

Which phone is the fastest to boot up?

This is not a question that you might be asking yourself on a daily basis, but since battery life is such a precious asset, and since people generally don’t like to be bothered at night, some manufacturers have built in the option to turn off your phone. If you turn off your phone at night, or if you are a developer who has to reboot the device multiple times, boot-up times do matter.

And it’s just plain fun knowing how long it takes for a phone to start.

So that’s why we took the device we had at hand and started booting, rebooting, and measuring the times. We tried this with apps installed, and with the phone fresh off a factory reset (hint: there is very little difference in actual boot times, only after you boot, some apps might start syncing and slow up the phone, which we are not accounting for).

And here are the results of our testing: the Android phones and iPhones that are fastest to boot in descending order. Any surprises?

Disclaimer: We’ve tested booting each of the phones several times to ensure the results are reliable, using the same method for each device. Start-up times still vary and the figure below should be taken as an approximate guideline with several seconds of allowed variability. Generally, results show that boot-up times can be faster or slower than the provided figure by up to 2-3 seconds at max.

THESE PHONES ARE FAILURES DUE TO NON-REMOVABLE BATTERIES. Boot time is meaningless on a phone without a removable battery.

Note 4 has a removable battery.

You are a failure since Note comes with removable battery

What's a removable battery got to do with boot times? I can sort of see the logic but it's hardly the ONLY time we need to power on/off our phones.

I don't know what's funnier, Qwerty's comment or the fact that some seem to have missed the sarcasm.

dude I'm sure he doesn't see that logic. he just had to say something.

I am curious as to how a removable battery makes a difference with boot times? Please educate us.

49. QWERTYslider unregistered

The only time I reboot my phone is when I hot swap for a fully charged battery. Note 4 isn't in the thread title. All those trolling me know what you can go do to yourself.

dude if you boot your phone only when you swap batteries, I have bad news for you: "you know nothing John Snow"

"Note 4 isn't in the thread title." -QWERTYslider The S6, M8, M9, Nexus 5/6, Xperia, and G3 aren't either. Your point?

More and more phones are going to come out without removable batteries. Sale records and survey indicate ppl don't really care about if their batteries is removable or not. Most casual phone users won't even know how many power their batteries have.

Rest in peace all the touchwiz haters. Samsung rolls. Look at the time of m9 and iphone plus. What a joke. Not to mention the stock android running nexus too.

Yes cause 28 seconds for the iPhone 6 Plus and 37 seconds for the M9 are just terrible, a person has to wait less than a minute for their phone to boot up, oh the dread! I don't even understand why this is an article or why it even matters. Only thing this article is for is to stir up fanboy wars. I have to boot my phone 1 time a month as i let the battery go completely down once a month, and i really don't think 28 seconds is going to cause me to have smartphone withdrawal. Get a life buddy.

Think PA might need to do S6 again, UK s6 32GB booting in 16/17 sec over here in UK. justsaying

This is really an article lol...... 25 seconds, 50 seconds, big deal. 1 minute out of your day wont change a thing. But hey, if you wanna stroke your penile instruments over this because your phone boots up in less than 30 seconds be my guest.

Then according to you speed tests are useless too. Milliseconds out of your day won't change anything

theres a big difference between reboot time and app time. Do you reboot often?

35. Sauce5 unregistered

He doesnt understand that. He doesn't understand that because he's blinded. He's blinded because he's defensive. He's defensive because he's closed minded. The list goes on.
