iOS 10.1 Battery drain

Yet every one of these people including myself had ZERO battery problems before the upgrade. Let me repeat that for you. ZERO battery problems before the upgrade. Why is that? You think it's just coincidence? Or maybe. Just maybe the OS is the culprit?

Umm sorry Mr Malanthius, I did. I tested iOS 9.3.5 until three weeks ago. I gave you pics with iOS 9.3.5 written. Battery scheduled to die 11-12 months mark. Maybe sooner. True, no shutdowns- yet. Another user came here, lost a 6 battery with iOS9. I hyperlinked iPhone 6S june 2016 issues forum link, before iOS 10.... Anticipating your reply, I got last night this link(s) explaining how hardware and software interact to protect a circuit. From Texas Instruments. Read the paragraph about programming http://m.electronicdesign.com/power-sources/protecting-your-lithium-ion-batterie s-isn-t-so-hard I believe you that many shutdown issues commenced with the 10 installation, but my decaying life did not, nor can we attribute short battery life to 10 explicitly. Some users installed iOS 10 on 3yrs/1000+ cycled batteries. Let us not speculate on how iOS 10 manages some parameters. What I do know is that our hardware has all those safeties built in to shut itself down (CBs built, such as the Li Ion self destruct fuse), and <30-40% are a magic battery clue.

I had zero issue before the upgrade, and zero issues after the upgrades. I had iOS 10 for three months before the first shutdown. My issue occurred between updates, days before 10.2.1. You cannot lump me as 'everyone'. Read his links, your answers are there, hes avoiding speculation to preserve the post. Check out online. Any program also helps with protection. The one time Samsung avoided it, catastrophe. Ideally, each iOS gets smarter with years of data. If engineers figure one more parameter indicating shorting batteries, I laud them. I like that. But I'd like it notified with pretty flowers, 😍 pretty smileys 😝 "Dear valued Apple Customer, your iPhone shut down to prevent further damage to your device's electronics. If the issue persists, please Call Apple Support or schedule a Genius Bar Service Appointment." I'd also like an immediate genius bar iCal appointment link geotagged with my location.

Si tu nas aucun cycle indique sur ton 6 faut lamener au Centre Apple Farview ou Apple Montreal. Des fois ca indique pas a cause des defauts. Les diagnostique vont dire pourqoui. As tu essaye Battery Percentage?

I recently went to check if there is a software update from Apple, and there was a minor version which was pending. So I went ahead with the upgrade, nothing to lose right!!!

Now I am on iOS 10.2.1 and it seems to be working; the battery drain is pretty much back to its initial level and haven't experienced abrupt shutdown since then (fingers crossed!).

So much for selling the idea of battery replacement, when clearly with a software upgrade my phone's battery seems to have rejuvenated.

Everyone else, hope you get to read this if some bots here don't flood this discussion with marketing messages for battery replacement!

Hey Alain, trick: when you insert pics here, resize them in the browser - grab the corner, so they take less space. So your 6+ is at 69%, 2 yrs old, 2-3 charge a day, need a charger, and does not even register cycles. There was another user with a phone at the Apple Store his battery had not registered on the diagnostics. Rogers, french, Quebec, got two nice Apple stores in Montreal, Qc City, plus more authorized centres, may want to do the free diagnostic apt.

Your article says what has already been said. If you had two years out of your 6+ (I am not getting one out of my 6S battery) I call that good stuff, it's due for maintenance. But would not compare the 5 with the 6+. Even the SE, a body of 5, will get 30-40% longer life than a 5. The 6+ was Apple's largest iPhone, higher amperage demand, larger screen, even browsing burns more due to screen size and larger html content load. At the two year mark it appears normal. Tas bcp de place a reparer pas cher. Booking an appointment is the best course anyone could recommend.

Ok, so if I use your logic,

My iP4 1420mAh battery after 5 year have 87% health (good) = Normal.

My iP6+ 2915mAh battery after 2 year have 45-79% health (bad) = Normal.

So, to extrapolate with your logic, the next iP8 with let say 4210mAh battery after 1 year with 75% health (bad) = Normal?

Did you take me literally? You know as well as I do that 99% of the problems started after the update. Defend it all you want. Yes a battery change fixed the problem. But is it temporary? Too soon to tell. And why was a battery change necessary when most of us had ZERO problems before the update? I hesitated doing the update because I was already reading about the battery problem caused by it. I took a chance. Bam! The day I did the update my battery took a dump. You can call it a coincidence all you want. You ignore the thousands of coincidences then. Haha!

A battery change has worked for some of us. Mine is two weeks old and starting to show signs of the problem coming back. Get ready to be told it's your battery and not the upgrade by a couple of people here. :D

Come Mr Malanthius, I read her posts and remember mine, none of us called it a coincidence. Why are you changing our words? even if Alain's article above does. I just refuse to speculate which one of the two dozen voltage or amperage control programming may tweak because A- Got no idea and B- post would get deleted. The bottom line is that your hardware recalibrated/reset to prevent your poor circuit from operating in certain conditions. And, if the battery resolved, you proved it beyond doubt, found your issue. Something else- a few weeks ago when I recommended a user your solution, I got a suspension warning. So I tread carefully on not advocating what you did or how you did it.

"Mine is two weeks old and starting to show signs of the problem coming back." Unfortunately, if you went through a DYI option, outside Apple Support, I forecasted weeks ago that your repair would not last. This is not about Apple, bypassed support, but simply product quality. On Amazon you have 3d party options frying phones not just fail in weeks.

Honestly Sam, you are ignoring those users whom tried 10.2.1 and it made no difference. Have you not read their comments? If it works for you, great, the reset reinstall (which it is) worked. Fine. Mitigate your expectations; good too many came back 24 hrs later to report it back, not the least Alexa and more.

I didn't call it coincidence, I actually thanked Apple for protecting me from a faulty device right? Did you actually read my post? Read the great links Beilsaruis sent you especially the part about cells not being identical.. voltage amperage temperature controls?"overheated or overcharged, Li-Ion cells are prone to accelerated cell degradation and can catch fire or even explode. Hardware and software protection is in place to mitigate these immediate dangers. No two cells are identical. There are always slight differences in the state of charge (SOC), self-discharge rate, capacity, impedance, and temperature characteristics, even for cells that are the same model from the same manufac- turer and even from the same batch of production."

At CCNY we spent a semester in school studying these things. We took high grade Panasonic batteries and tested them nonstop- frequency, voltage so on. They were not identical, but safe and long lasting. We also took cheap fake batteries, like the one it seems you installed. Hook them up. Temperature sensor on. The tests would not last 5 minutes, overheating and catching fire with minimal stress. The cheap controller could not regulate the current. Yes, like that link given to you days ago, 99% of online replicas are bad. Very bad. Coming here and telling us that a self tinkered battery degraded rapidly has nothing to do with Apple or iOS.

Guess some will like or dislike the Apple news. Have yet to see an iPhone 7 or SE coming here. All running same iOS 10. Is there x78.3 millions coincidence that they work? Newer hardware, no issues, older hardware, some issues?

Alain, you are comparing apples with oranges. Your iPad battery is rated for 80%1000 cycles, 11500 mAh, nearly 8 times more vs average cellphone batteries. Different power source, different cell, no issues with them for many years. Because they stay home, controlled environment, no cell antennas, lower demand, the last many years. But your 6+ is twice the size of a 5, burns more power; but iPad is the king of all. I hope you do iPad backup and update iOS to 9.3.5.
