iOS 10.1 Battery drain

I just downloaded iOS 10.2 so we will see how this goes. My phone is currently @ 99% and holding where it has dropped down to about 90% by now. The real test will be whether it shuts down, or keeps going. Either way I will be getting my battery replaced Saturday under the iPhone 6s battery replacement recall. keeping fingers crossed.

OK. That was a no go. Phone shut down @ 76% after update to 10.2. Come on apple. Your better than this.

I have an iPhone 6 and the problem of unexpected shutdown and battery drain applies to my phone too, and has been getting worse since iOS 10.1. It now shuts down even with 90% battery - and shows zero until I plug in a live charger, at which point it jumps back up to 90% or whatever. I travel a lot and app store geniuses in Honolulu and Tokyo have been very supportive, offering to replace the phone, but unfortunately both replacement batteries and phones were out of stock and I had to move on before they could replenish the supplies. Currently in Vietnam for a couple of weeks, so I have bought a $250 charging case which has enough power to get me through a day.

It is unfortunately increasingly difficult to justify my preference for Apple products.

Yep its happening to me again now since updating to 10.2, I have a 6s.

I used to have so many issues with my battery dying anywhere between 60-30%.

I went to the Apple store here in Sydney (City) and Miranda, both times I was told that there was no issue and that it was all relatively normal, even that I was just using my phone a lot! Seriously...

I begged Apple for a new phone/battery, but they wouldn't budge, in the end I fixed it by completely wiping my phone and re-installing my apps 1by1. I lost all my messages... That did fix the issue though. However, since upgrading to 10.2 looks like the bug is back. My phone just died and asked me to plug in the power, looked at the battery after it turned back on 32%.

YOU SUCK APPLE, FIX YOUR SOFTWARE!

I have an iphone 6splus iOS 10.1and has the same problem as above . As soon as it reach 30% iPhone shutdown itself and have to restart multiple times to make it work and shows again 30% or less than 30%..

hi all

not much to add than... my iPhone 6s is doing the very same since iOS 10.x is out: it shuts down when battery is still at 30% if I make a phone call or I use wi-fi 😐

10.2 didn't change a thing 😠

Getting worse for me. Shut off at 90-92% a couple of times today.

Same problem but sometimes my 5c can be just under 50%. It's been annoying but the other day I ended up stranded because of it. Several friends are having the same problem. Yes there are newer models but I'm one of those people who doesn't replace something until I have to.

I have the same issue.

I have a 128GB iPhone 6 (not a 6s) which was working without any issues until the operating system upgrade to iOS10. After the upgrade to iOS10, I have experienced the same issues reflected in the first post.

When using the phone, the battery percentage indicates a rapidly draining battery (the displayed percentage drops quickly) and shuts down when the displayed percentage indicates the software believes the battery has been depleted. Plugging the phone into a charger immediately results in the phone powering back up and the displayed battery percentage shows a healthy amount of charge remaining (~45+%, it varies). In these instances, I am also able to restart the phone by holding down the home and power buttons simultaneously (and the displayed battery percentage reveals ~45%+).

Needless to say, I've tried everything. Aggressively kill applications in the background, turn off all widgets, restrict location services, etc. Nothing has worked.

I was hoping 10.2 would solve this problem. It hasn't made any difference.

As a heads up to anyone thinking of taking their phone into the store:

I made an appointment at the Genius Bar to diagnose this issue. They diagnosed the battery as being healthy (well into the green area on a box diagram they showed me). Unfortunately, their only resolution for this issue is to replace the battery (and charge me for it because the phone is over a year old). However, the battery, as diagnosed by Apple with their own diagnostic tools, is fine (actually, more than fine).

The genius told me that the best thing to do at this point is to reset my phone (and install everything from scratch, not my backup) and see what happens. I'm sincerely hoping this solves my problem, but I'm not optimistic.

Needless to say, I, like many people on this post, am pretty frustrated at this point. It's extremely frustrating to have your phone die randomly, or maybe worse, when you are trying to take pictures or videos. It's also extremely frustrating to waste your time scheduling a Genius Bar appointment days in advance and taking time out of your day to go to the appointment when Apple doesn't seem to have a solution to this problem (or even admit there is a problem).

Like many people in this discussion thread, I have been a reasonably loyal Apple customer for about 17 years (many, many devices and computers), a large part of this loyalty was based on my experience that Apple worked quickly to resolve issues that arose with their products. In the past, the support I had received at the Genius Bar had been very good (sometimes exceptional); Apple made me feel valued as a customer. My recent experiences with my phone and my last Genius Bar experience have left me wondering whether Apple is taking a less supportive view of customer service.

My questions to Apple are:

1) Is replacing the battery (and charging the customer around $90 for it) a sensible resolution to this issue when the battery holds a charge and Apple's diagnostic tools indicate that there are no issues with the battery?

2) Is Apple exploring the possibility that changes introduced in iOS10 have introduced a significant flaw where the battery charge is misread (and, as a result, the phone shuts down prematurely)?

3) At the time of my posting there were ~730 posts and ~60k views of this discussion thread. Is there a system at Apple, where the most active threads on the support forum help surface bugs for the software engineers to address?

iPhone 6. Exactly the same issue. It shuts down at about 33% and shows the battery empty screen. Furthermore my battery is draining really really fast. It happened with 10.2. Everything was fine before. This really *****. Apple please.

Otro con el mismo problema, tengo un iphone 6s de 64 gb y se me ha apagado un par de veces al 30%. Lo que va fatal en mi caso es el porcentage, baja como quiere, anda loco. Pense que 10.2 lo solucionaria pero no ha sido el caso. Apple va de mal en peor, ultimamente no hace nada bien.

Okay people, here's my latest update. I have an IPhone 5s. I updated it To iOS 10.2. My battery literally went down to 2% and was holding before I decided to charge it up. It didn't shut off at 35%. I'll see how it does this weekend. Could it be a fix they have slipped in?

This may seem like a drastic solution, but is there anyway to revert to the last iOs version 9.3.5?

I have an iPhone 6 which has endured battery drain / shutdown problems since upgrading to 10 and each successive version. I am about to give the phone to my teenage son, so I have no qualms with wiping the unit clean and starting over. There are numerous download sites which offer the last iOs version 9 .ipsw file.

Forgive me for not being more knowledgeable, but can the phone be wiped and the old iOs 9.3.5 be loaded?. Even if it is not possible for the consumer to do it on their own, has anyone ever asked Apple / Genius bar to do it for them (even for a fee) ?

Apologies if this is a naive question or has been asked before,

Thos.

The latest you can go to is 10.1 I believe. Below that version the software is not signed. Now, if your phone is jailbroken, then there might be an option.

10.2 didn't correct the issue on my 5c. Battery consumption is horrible! My iPhone's battery still drops in huge percentage leaps and then goes dead, only this time it went dead after 1%, not 30% so perhaps 10.2 corrected that issue. Once I reset and plug it back in, then it immediately jumps to 40% capacity. Doesn't make any sense. I really needed a reliable phone yesterday as my family endured an ice storm in Oregon. After losing power, my iPhone lasted only 2 hours on light use (checking emails, weather, and text messaging). I was sitting by my fireplace so battery temperature had nothing to do with battery drain issue. What's the point of having a cell phone if it needs to be plugged in all the time?! My iPhone used to last all day before updating to 10.1.1 and 10.2; only charged it at night. This is unacceptable. Apple used to the be goto company for hardware and software reliability. They've lost that status in my opinion.
