I suspect this is a hardware (firmware) issue, I've had it, along with numerous other people and a replacement followed by an iCloud backup has always fixed the problem. It's not normal battery drain, nothing could cause the battery to jump from 30% to 0% instantly. It wouldn't explain the percentage jumps when plugging back in, or how usage in the cold causes shutoff when under 50%. I fear Apple knows there is a def…

I have same problem with iPhone 7 and iOS 10.1.1 Just started yesterday. My phone gets hot (not Samsung fire hot, but pretty warm) when the battery level is plunging, which suggests that something is actually chewing up wattage. At least in my case.

I have no doubt there are battery issues that can be software (I remember IMAP issues back in the iOS4 days), but I think there is clearly a distinction between software bug battery drain issues (hot phone, slow consistent drop in charge) and this sudden shut down issue, battery percentage jumping by 10%/20% up and down when connected to a charger.

This is the same treatment my iPhone 4 got after few updates. I suppose it's a standard way for Apple to deprecate old hardware. Those phones won't sell themselves!

I've been having these issues in the past week or so. I thought it was just my battery that was dying!

Just one extra datum, there gas been normal battery use on my iPhone 7 since the update, though I don't think it has ever dropped as low as 30%, despite a fair bit of Bluetooth headphone use.

I was experiencing this earlier in the year but it didn't go away after factory resets and a downgrade to iOS 9.2. Which made me suspect iCloud Photos (with "originals in iCloud" setting) since taking photos would reliably trigger "warm phone", especially in low connectivity areas. A suspicion which was heightened when the same phone in my Mother's hands (no iCloud Photos) was perfectly well behaved battery-wise.

iOS 10 issue I've had, haven't heard of many others with it? When you answer incoming calls if it hasn't been rebooted in a few days -- the call timer ticks but no audio happens. Press the keypad/speaker/etc buttons a few times and the phone locks up and requires a hard-reboot. Hangup button seems to work if you do it within a few seconds, otherwise the phone locks up.

Anyone else have this happen? (Carrier: EE in the UK)

I got an iPhone 7 basically on launch day and had terrible battery issues up until last week, when I decided I had had enough and went into the Apple store and got quite animated until they finally agreed to swap the handset for a new one. Since then I've had no problems. Things I tried multiple times in different ways:

Reset all settings

Run battery to flat and then charge to 100%

Restore entirely from backup

Look at running processes with Instruments (normally MediaAnalysisD was pinning the CPU even when in standby)

Switching basically everything off (background refresh, mobile data, etc.)

Nothing made any difference at all.

The battery was draining at roughly 1% every 8 minutes, even when it was in flight safe mode. In use, I would be at 20% battery by the end of the day, whereas my old 6 would normally be at 60-70%.

There is definitely something going on that Apple can't work out, even when they run diagnostics on the handset.

Their solution in store was for me to format the phone and run it with nothing installed, etc. for a couple of days. I basically expressed clearly how this wasn't an option for me after having paid so much money for a device that I'm reliant on for business communications and eventually they gave in and swapped the device, since then it's been a night and day difference. I get to the end of a day on 75%.

This has been my experience in two of their stores in London. One of them even decided not to cover a defective product for free 1.5y after I've bought it in an EU country which gave me 2y warranty. I had to fly to that country to have it immediately replaced, for free. This one was really awkward since they have it on the system, they know when and where I bought it and under which terms and still decided not to help me. In my experience it's by far the worst customer support I ever had.

Same exact issue here. Bigger mistake on my part -- upgrading before a long international business trip. To make it worse, Uber has also released a series of updates recently on iOS (four updates in four weeks?) -- made traveling very complex because of application instability.

Lesson Learned: put off system/app upgrades until after travel, stick with the tried and true.

I'm used to this for work (e.g., always perform upgrade on Friday afternoon after close-of-business) but it is a new phenomenon to apply my work practices to my personal phone!
