Iphone 6s Battery suddenly draining

basic answer but already tried that, can watch my 6s battery drain as i use it which is nuts, apple store checked battery life, is at 98% so it's not the battery, all they could tell me is wipe it out and start over, or of course get a new phone, which is what they really want, what a scam..

This thread began in June but now it’s October 25 and people are still reporting the problem, so I’ll join in. On my 6s, Bluetooth is the culprit. It seems to be turning itself on even when I’ve turned it off using “settings”, and when it’s on it drains the battery very rapidly.

I have the same problem! Suddenly in the last couple of months, my battery will just drain all of a sudden. I got a replacement battery a year ago, and even took it to the Apple store again, and they suggested turning off all background app refreshes... didn’t work. Not exaggerating, my phone just went from 62% to 17% in the last 20 minutes. It went from 20% to 17% in the time it’s taken me to write this post. Then, I’ll charge it and it just jumps by 15% all of a sudden. Ridiculous move to make you upgrade.

I highly doubt there will ever be a fix for this. My phone battery drains 15-20% per 3-5 minutes when in use, and about 30 minutes to an hour when not in use. This began happening when I upgraded to iOS 12 and has gotten progressively worse with each update. I have all of the “options” turned off because I have no need for Apple or any other app to invade my privacy.

Every single response is “replace the battery” or “replace the phone” when thousands upon thousands of people are experiencing the same issue. That’s a scam, straight through. They want more money, they won’t fix the issue and this is likely the reason I finally ditch iPhones. Several months of constant reports from people across the globe. Zero responses from any tech or customer service member that doesn’t involve paying Apple more money, and the most infuriating part is that people with brand new batteries STILL have the same issue.

Get your sh** together Apple support, for f***s sake.

I appreciate the thought but I never have Bluetooth on either. I don’t have screentime running, none of the analytics besides battery percentage. Location services are selected off, etc. I attempted every online fix I saw before losing my temper with it last night, so I feel fairly justified in it.

Hello,

There can be several reasons for your battery dying fast. You cannot stay on particular reason for the battery draining as several things can be considered for your iPhone 6s problem. Well I would like to guide you few tips on how to boost your battery life longer.

Tip 1: Check for the apps that consuming more power

Tip 2: Switch your phone to ‘Airplane Mode’

Tip 3: Update your iPhone/iPad

Tip 4: Remove unwanted widgets on lock screen

Tip 5: Switch off ‘Wi-Fi’ when in not use

Tip 6: Update all Apps on your phone

Tip 7: Use location service when required

Tip 8: Switch off Bluetooth service

Tip 9: Close the apps running in background

Tip 10: Switch off Raise to Wake on iPhone

Tip 11: Change the battery

These are the few things that can surely help you to make your iPhone battery last longer no matter whichever iPhone model you use.

Best of luck...

I’m in the same boat: for me the problem started last month (way after iOS 11.4). My daily commute is 35 minutes and when using my iPhone for some reading and music it drops more than 50% during that time. Overnight it easily drops 40%. When in use I can watch the % go down, usually 4-5% in a minute after which it stabalizes for a few minutes.

Restoring the phone did not help. Battery health was at 82% but peak performance throttling was activated after the phone once died at 20%. I purchased a new battery but that did not help 😡

i now did a complete wipe and clean set up of the phone. It did keep full charge overnight (99%) indicating there is a software issue with one of my (now deleted third party) apps or the OS itself (iCloud sync?) but as soon as I picked it up and started using it this morning, it immediately dropped 5%.

The battery indicator turns yellow orange to indicate that your iPhone is in low power mode to reduce the drain on an almost empty battery. Even after you plug in to charge it, the indicator won’t turn green till your battery level reaches 80%.

I have been frustrated by the demise of the performance of my iphone 6s for over a year. Being a creature of habit I have managed to fairly scientifically determine possible causes.

Situation:

I purchased an iphone 6s new from the apple store in June 2017

Since being available the maximum capacity shown in battery health has been fixed at 82%

Usage:

I charge my phone overnight and use it for reading the newspaper in the morning and then use strava and a bluetooth heart rate monitor to track my morning commute. I will use for music streaming with spotify during the day as well as the occasional email / text or phone call. I track my return journey using strava along the identical route in the evening.

The issues:

Battery percentage falling rapidly - the percentage of battery power will tick down every few seconds when being used during morning commute.

iphone will crash at exactly the same point on my morning commute using strava - this is not impacted by battery level, changing to battery saver mode, disabling wifi or bluetooth (not great when trying to use a HRM).

When restarted following a crash the phone will either crash again once unlocked or show the charge battery symbol. Once connected to a charger it will restart and show a battery percentage at the level prior to the crash.

Curious to note:

When I do the reverse journey in the evening using the exact same settings my battery usage will differ greatly from the morning performance. I commute by bike from south west London into the City, in the morning at peak commute hours (between 08:00 - 09:00). In the evening I usually leave after the peak commute (19:00-20:00). When I leave during off-peak hours my battery usage on the identical route can be less than 3% with no crashes. If I leave work earlier the performance matches the morning.

Partial solution:

I have managed prevent the crash problem by disabling mobile data. The battery percentage will decrement at a lesser rate than the normal morning level but greater than the evening usage. Once home and connected to my wifi the phone will usually crash and only restart with the power, returning to it's previous level.

The statistics provided via battery usage seem bizarre and I suspect there is a limited value in this data and it is simply allocating the amount the battery has reduced in the time period by the number of apps in a simple weighting. I would have expected that the OS would appear on this list either directly or through related actions on wifi / mobile data usage but this is presumably lost in the app allocation.

I have disabled the performance management feature to see if this makes any difference to my issues however this feature has no impact on any of these issues.

My suspicion is that the effort of trying to connect to cell masts / wifi hotspots is at the root of this problem as this would explain why the identical usage at different times is so inconsistent, with London being highly congested, especially given the fact that it will crash at the same physical location when enabled. What I find frustrating is the lack of transparency or ability to manage this at a level other than on or off.

I am in the process of getting a replacement battery which I hope gives me some (most likely temporary) relief although given that this has been a persistent issue since the battery was less than a year old I am not overly optimistic.

My overall impression is that there are known issues with older phones and the iphone 6s in particular. I had an identical phone from my former employer which, like my current phone when first purchased performed perfectly well under the same conditions for a period of several years. Since the only variable in the equation has been changes in iOS I must assume that this is where the performance problems were introduced. It is amazing that performance of a simple task can degrade to the point of rendering the device defunct in such a small time frame (written on an 8 year old acer laptop that I can still use for my basic needs).

On a lighter not, having a family of 5 iphone users including myself, the move to an android device for my son earlier in the year (google pixel 2 plus - £629) has been completely without any issue (barring getting his icloud email to work on an android device - much harder than enabling my google mail on the iphone). In fact my mother-in-law appeared at Xmas with a Huawei Mate and required no more support than on her previous iphone 5s (which was provided by the 12 year old). Cheaper, faster and better? User friendly??

Apple were built on the concept of paying a premium for a better user experience, my personal experience is that the offering is now paying a significant mark-up for a worse experience, which is not a great position to be in.

is this an old issue or just since uploading latest iOS in December?

since downloading the latest iOS both my wife and my iPhone 6 have been draining battery overnight or after a few hours use during the day

I started noticing serious battery drain in the summer of 2018.. so I got a new battery and it didn’t solve anything. I lost 1% just typing that last sentence. No, actually 2%. And so on.

siri off.

Bluetooth off.

No apps running in the background.

Settings-privacy-location services: Most are never, the rest are “while using”.

Settings-general-Background app refresh: Off.

Notifications: most are turned off.

eventually i’ll have everything disabled and then, maybe then, the battery will last through one day when in standy, becoming an unusable device. But i doubt it.

There is no way my old battery (at 80% health) and my new battery (at 100% health) should die so quickly doing a fraction of the things i was doing less than a year ago.

you know how when a phone is working hard and processing a lot (like games or displaying a movie), the phone gets warm? that’s when you know, understand, and accept some battery drain. but as i hold this phone, it’s still stone cold. I’ve lost 10% just typing this post.

Yeah I know how you feel. Got the same problem here with my iphone 6S. Battery health shows 99%. But will drain quickly if I use the phone, or lose about 10% an hour idle with no back ground refresh, no push , no notification etc etc. Common theme appears to be an iOS update. For me it happened after installing iOS 12.1.1.... 12.1 was fine. 12.1.2 did not solve the issue. Nor did setting the phone up as new with no apps at all after a clean wipe. Hopefully it's something that will/can be fixed via iOS update ..

Wonder why it is just the 6's.. I have the 6S Plus. My wife has the 5SE and she can use her phone all day and sure, her battery goes down quite a bit, but it's still the original battery, and she's got tons of push notifications etc and never closes any apps and didn't remove any location services. She uses her phone like normal. I had to start babysitting mine.

Ah ha - thank you for this! My iPhone 6s yesterday drained from 87% to 3% during a 15-minute train journey, which was somewhat alarming as I had another 1.5 hours of train travel ahead and the phone had my mobile ticket on it. I couldn’t figure it out but I guess you are right...upgrades & connecting to hotspots could be the culprit. Still pretty appalling though - as others on here have reported it is just 2 years old and battery is allegedly 87%.

I have already purchased mobile tickets for future train journeys now I wish I had good old fashioned paper ones!!

I have a iphone 6s which is 2year old. Suddenly i noticed that my battery is draining so fast that from 50% to 0% in overnight. While i am not using any apps and even i kept in night mode to check the solution but it doesn't worked out. So when i checked Battery health it is 79%, So straight away i went to app store got my battery replaced. Now battery health shows 100% but still its is draining that fast only. Even i tried complete reset and bringing back up from cloud. Every possible thing i did and it doesn't worked out, Can someone suggest me the solution how to fix this. I am really annoyed with this thing. Apple plzz help
