That looks pretty good. Did you do a clean restore and set it up as a new iPhone?

I'm on 9.3.2 and I'm planning to upgrade to 10 over the weekend. I'm guessing this is a dumb question but can someone tell me why should one do a fresh install?

Wouldn't you lose your apps, app data (like WhatsApp chats for example) and any settings you may have modified?
Is it really worth the effort?

We pay hundreds of dollars for these phones, then people say "o no you have to install as new".

It's a kneejerk response from wannabe tech supporters. Same as "Have you tried to reinstall Windows".

Just ignore it.

Well, when people have battery life issues, usually doing a clean install fixes it. The whole point of doing a clean install is to avoid those issues in the first place. I personally like to do fresh installs with every major iOS update. I've noticed the phone to run slightly faster and smoother. It's not a myth. It's really true.

It's fine until you start adding all your apps back, and then find that the phone is running the same as it did before the clean install.

I just did a complete restore on my device because I am having Bluetooth problems. I didn't install one app, waled to my car, and the same problems plagued me. I know this isn't the same situation that the poster was asking, but still...

With that said, I don't do the Delta updates (over the air). I prefer installing from iTunes where the whole OS is downloaded to my computer. Make me feel better doing it that way :)

I usually do the delta updates OTA. Although a lot have complained that it destroys their battery life, it's been fine for me.

what a bizarre thing to have to do, clean install everytime a new OS comes out so you literally lose all the stuff that makes it your computer, lol.

Plenty of times resetting something or other or even reinstalling can resolve various oddities. It doesn't mean it resolves all issues or all the time, but can be something worthwhile to try for someone that is having some issues that aren't necessarily widespread things.

Not really something you need to do to upgrade. More if you have some issues and might be trying to resolve them. (There's also the whole concept of a backup that could usually be used to restore when reinstalling.)

I've just hooked up my 6S Plus into Coconut Battery and I'm shocked. Apparently it's at 85.6% of design capacity after 275 cycles (379 days old). I'm really starting to think there might be some truth (even if only a little) in the thoughts that Apple deliberately programme their batteries so that by the time a new phone comes out your current one will take such a hit on the battery life that you think "sod it, I'll get a new one". Yes I'm paranoid, but it doesn't always mean they're not out to get you :)

Sorry, just not true. My two iPhone 6 phones are two years old and still in the high 90% range for capacity. My charge cycles on those phones is a lot over than yours, but that's the point. These batteries wear with use and what you're seeing is just chemistry, not a conspiracy.
[doublepost=1474475758][/doublepost]
Variance. Batteries are chemical things. Capacity measurements are estimates, combining and estimated original capacity and sn estimated current capacity just isnt going to be accurate to any great degree. What IS known and accurately measured is the degradation of the Li technology.

That and the fact that some people's charging habits are different. Constantly running the battery from 10% to 100% to 10% and so on is going to wear a Li battery faster than someone who can manage to hover in the midrange (say, 30% to 80%). I recognize that the second scenario may not be realistic for a lot of users.

Took my 6S in to have its sceeen replaced today but didn't get to ask about doing a test on the battery. Apparently the phone failed a "calibration" so they swapped out the whole phone for the price of the screen replacement. The 6 has been behaving better today for a two year old phone so I'm going to let that slide a while.

Been on iOS 10 a week now, as much as i love it over all, the battery life on my SE is considerably worse. I would typically have 50%+ left when i would put my iPhone on charge at bed time. Since iOS 10 i'm down to 10%ish most nights. I've got another 2 hours before i go sleep and i am on 21% :(

My battery life is worse on my 6s Plus running iOS 10 than it was on iOS 9. I would see my battery not drop to 99% until it hit anywhere between 38-45 minutes of usage (not standby) consistently. Now, I'm lucky if I get to 28 minutes of usage before it drops to 99% from 100%. Every percent drop after that is a rapid decrease as well. I hope they can fix this soon.

Seems like 10.1 beta 1 will fix battery issues, I updated to ios 10.1 beta 1 and for continuous use of more than 2 hrs of video, browsing etc, i am only down from 54% to 37%.

Still it is too early to tell and ios 10 beta 7 had great battery life, time will tell.

Maybe someone can see as per previous posts cpu usage diff between ios 10.0.1 and 10.1.

Do you guys maybe think apple is purposefully destroying battery life on the GM to get people to purchase the 7? Haha


Yes always appears to be 2 years old the phone stops as for the battery drain I agree at present I change my phone it shows 50% jumps to 20% turns off like the battery has died

Today i just downgraded from ios 10 to 9, Apple is still signing 9.3.5 but next tuesday will be 14 days and they use to stop signinig old firmwares after that period...mmmm

RE: restoring vs. fresh install. Fresh install should be a last resort. I carried an OS X installation from Tiger to Snow Leopard and an ios installation from ios 3 to ios 6 without ill effects. I started fresh with the former because of a drive failure and because I could (selective restore from Time Machine) and the latter to rid myself of possible remnants of jailbreaking. Mostly, Apple does a great job with upgrades and fresh installs are low effort (but potentially high impact) shortcut to troubleshooting.

My zero point zero two dollars.
