iOS 10.1 Battery drain

Quite the contrary. And when you go far away, manage eighty hours a week equipment, materiel, people's lives, cognitive psychology and deliver effects in time and space, it takes a lot more than 2 bits. Be silent for days and say one sentence that makes your boss change the course of an entire project- and it succeeds. In any field: arts, athletics, car racing, and even basics of science. If you do not know that Apple uses ARM processors, whereas Android devices live and breathe on Samsung processors or hardware, not my fault. As a former european, if I am a betting person, you would never choose a Lada versus a Skoda or Renault, or a Kia over a Volkwagen or BMW. You do not have to be a mechanic to understand a quality nomenclature, but, technology wise, this escapes people.

That's the silliest two liner you have yet to come back with. Corning made 4.5 billion Gorilla glass screens, is your iPhone called Corning? Or Macbook Pro Intel because it uses Intel i-5/i7? Nope. The point was, when you say Android, you essentially say Samsung, the same way LG and its mega factories dominate the monitor market. Could be a Dell Ultrasharp, but with an LG panel. Several manufacturers make Apple parts, flash drives, NAND ram, etc, including Samsung. But ARM is not the same Snapdragon 820 processor Androids buy or use. Not even the same performance, always less. Same for any other module, they all are Apple's spec and these manufacturers, or their micro circuit factories, are hired to make x millions. Different design, different QC, different story for Android. The manufacturer could be oblivious to the entire R&D or engineering process, they will just program the computers, let the lines print them.

Do admit, am impressed your going about reading on the subject. Only thing that can make me happier is your shutdowns resolving.

I'd dare say "no", but I'm afraid that could be misunderstood by some users here XD

To me, it's a little too draining but it greatly depends on what you have at the top of your most energy consuming apps. Some are heavy hitters on the battery.

I've just disconnected my iPhone 6 from charging (from a MacBook Pro, using an Apple original lightning cable), after it has been overcharged for a couple of hours and after 27 minutes of web navigation on Safari (no video streaming, just reading articles and posting on forums, I'm at 97%, meaning I could keep on doing this for barely 1 hour and 40 minutes, of the drain is constant... I'm sitting at 9 feet max from my router and using 5 GHz network. It's a little too draining for my taste :/

Agree with you, and no actual idea out of a pic, difficult to tell. Yesterday I used Uber twice, 10 min each. battery matrix said I used Uber 44% of the time. what I think this app tells us that in the time I used the Phone, Uber used 44%. Rest of the day the phone was standby, and Mail took the second spot. Today Mail says 69% as background; but with phone in standby, am down to 70% after 19 hours. Perhaps it means that 69% of the 30% I used thus far was mail background. I think the way you and everyone else are doing it, counting and keeping stats, is the best way.

I've come here to say that I have an appointment to have my phone analysed at a authorized Apple Store tomorrow morning (in Brazil, so I don't know what time will be in your countries). The attendant I spoke to the phone with told me the analysis result is imediat, but the repair of any component, if needed, will take up to 3 workings days. So after the possible repair, I'all be back with some updates. Wish me luck, especially in what concerns the possible price of the repair

Boa sorte! If they offer 3 working day testing, although inconvenient, I recommend it. Very thorough, they will do stress tests. A full reset if they do have to replace components is also a great idea, they usually do it. Also finger crossed they have parts, there is news of 6 replacement battery stocks being low.

iOS 10.2.1 is out. I am downloading it while I type this. Hopefully it has a fix for this issue on my iPhone 6. My iPhone 5S is just fine all along since 2013.

FYI: Release notes doesn't mention anything regarding battery issue. Hoping for an early Easter egg here.

After updating to 10.2.1 a new bug was introduced to my iPhone 6. It seems it's a way for Apple to fight the battery issues but it's annoying, it's bad and it's unprofessional.

I noticed the issue since I am always using my iPhone on 100% due to eyes condition.

Right after the iOS update 10.2 > 10.2.1 my iPhone rebooted on 50% brightness although the slider was to 100%. I never set autobrightness to ON neither set the Low Battery mode. At that point, the device had about 40% battery remaining.

I left it to charge overnight and the next day the device was properly on 100% brightness so I thought this was a once-off issue.

No!, Of course not. I fell victim to a bad bad bad workaround.

After using my device to browse news (pointing this out since this is my daily routing during that time) I noticed that right after hitting 70% of battery remaining, the screen dimmed again.

I checked and this time, the slider was on 100% but reducing down to 70% had no effect.

So, this verifies that this dimming is intentional, it was introduced on 10.2.1 and it most probably is there to workaround the battery draining issues.

For me, having the eye condition I mentioned, dimming the screen to anything else than 90% is a no go and I cannot use the phone. So, Apple destroyed my iPhone.

I am going to an Apple store and raising a claim for my device to be immediately replaced as it doesn't conform to what I purchased.

dino, the good news for you is that your issue has a solution, is resolvable, quite a few have done it here. Depending on your hardware age, after diagnostics, Support may determine what is going on. No, it is not the iOS, for several reasons- one of them is that there are 30,000 english youtube videos of iPhone 5 shutdown (English), many identical to yours, going back years, 2012, 2013, 2014. Long before iOS 10- which shares architecture with iOS 9 and 8. You will also find videos with owners explaining how they fixed the issue, including authorized center made videos. The troubleshooting steps are the same- Genius or Sr Service support, diagnostic, hardware evaluation. if something is out of spec, e.g. battery, that is a good start. If old or defective, it is exactly the same way it would behave, triggering an electrical safety shutdown.

It's really annoying!!!

Yesterday at 1pm my Iphone 6s suddenly shut down at 73% battery charge. After plugging in my battery pack for about 5-10 seconds the Iphone has rebooted and worked again until the night. At 11pm I had battery charge of 47% (without charging meantime).

This issue is now upsetting me for several months and it's an outrage how Apple is treating us.

My next smartphone is definitely an Android.

"Support told me to pay for service on a product problem :-(" Phone Support or Store? Sometimes, store and manager relative, quite a few users had unexpected courtesy repairs/replacement. Maybe you have a good relationship with a store staff? Apple Sr support has also helped some with preauthorized shipments etc.

I just wanted to say my battery issues have been solved through this iOS 10.2.1 update. I went to school for 6 hours on 50% with intensive usage with snapchat, Facebook and instagram and now ivdfinished with 38% which is really good. I guess it sorted itself out.

"Upgraded" to 10.2.1 with hopes that the inconsistent battery readings that cause shutdowns would stop.

Unfortunately, there is zero improvement and battery percentage still jumps all over.

Also, my voicemail bug continues, where I click the "play" icon and it starts, but then stops immediately as if it shut down an app. It happens multiple times. It's pretty clear, iOS 10 is riddled with bugs, but both the battery reading and VM bug should have been addressed by now.

And before our War hero/renaissance man adds their 250th + comment.. A

new battery will appear to help, but it is only putting a bandaid on the issue. The new batteries are new and will of course be able to perform better than the battery it replaced. The key takeaway from most folks posting here on the forum is that Apple themselves confirmed that their batteries are in fact healthy, so can only deduce that this continues to be a battery bug with iOS 10 (along with other bugs!)

So Apple - please fix. Thank you!!

Dear feinepotte, I sense your frustration, and no maliciousness, so will do my best to answer you diplomatically. In fighter tactics it is called the OODA loop, invented by Boyd. In science, sports, technology so on, we call it ODA, Observe, Document, Analyze. All you have to do is save emails or resolution stories and you know what happened. This is why you can count on one hand, few fingers, those whom had a healthy battery replacement fix. Two were recalls. The vast majority of others had old or expired batteries. Some had outright full phone replacement. It matters; if you look yesterday, one at Genius Bar , whom argued for days his is IS FINE, only to return reporting Genius Bar found his battery not even pinging/registering in diagnostics, or paikinator, with 20% health iPhone 5. They are ten percent so it all matters at pointing out that it is not how you worded it... if you go reread the entire forum, many resolution stories are missing. Some had Apple Support resolve it, but came back here with insults, so were deleted. Or two with DIY risky 3d party options, not approved by forum guidelines. And so many users here still awaiting for /going for diagnostics right now, so NO, what you wrote about most users having Fine batteries, is, factually, not quite so.. Especially for iPhones 5,5S or 6 with 700+ cycles. If anything, stories with Fine/Recall, or genya's low cycle/Fine battery are quite rare. And, yes, as people's success stories come about and corroborate technical science, across countries advisors say the same thing, or in time, having been told the same years ago, put yourself in my shoes and understand why I answer, at times, very assertively on specific points. Like, for example, uncontrollable, unsolvable drain and shutdowns are not normal and, in engineering, always, always, always taken as a circuit issue.

Voicemail bug: GOOD NEWS- you are the FIRST one to report it an NO, it is not an iOS 10 specific issue. It is a random iOS issue. Nor a battery issue. Like the earlier brightness story, they are just bugs, read seen or had them for 7 years. Apple Support, Forums or even Genius Bar should resolve it for you. Reset or advanced Genius Bar firmware resets usually resolve them.

So, I recommend you take it step by step; resolve the software bug first; then isolate the shutdown issue.

I have the same problem with a iPhone 5 IOS 10.2, it shutdown at +/- 30% battery, plug it in the power cord, and it still show me 30% battery remaining. Sometimes make big jumps in percentage... Updated to 10.2.1, lets see if resolve the problem, but from what I've read on tec sites, the problem still persists. Come on Apple...
