i'm going full OCD on this and i need to know why this is happening..

i have a 6S+ since November,
and the battery was kept perfect when on standby.
perfect meaning i charge it over night, and could be on 100% if the phone is unused.

well, it's now started draining even when i don't touch the phone at all.
i lost 4% in a few hours.
it's only on WIFI, and i have no background services or anything.

what happened? is this has something to do with the IOS (9.2.1)?
did i change something by mistake?
please help me solve this.
thanks.

Have you changed anything around the time that you started noticing this?

Have you tried restarting the phone since then to see if that would make any difference?

a regular shut off and restart? of course, yea.
this will drive me nuts! (thanks for helping btw)
can the Iphone battery get "tired" after 3-4 months?

It depends on how you treat the battery. If you are using it in extreme temperatures, such as charging the device while gaming, causing the device to heat up, that could hurt the battery. Batteries biggest enemy is heat. Second to heat is allowing it to completely die often. I always monitor the temperature of my battery, and never let it drop below 5%.

Losing 4% in a few hours isn't bad IMHO

sure, but that isn't the issue..
i didn't lose that % a week ago.
so i just wanna get to the bottom of this.

thanks.
but i don't use it in extreme heat (and he phone never got heated that much anyway),
i don't charge and play,
i never charged it under 50-40% since i got it..

it's now losing 1% in an hour for no reason at all.
 
Same here, insane drain on battery. This is on a regular 6S though.

My phone also shuts off now when I have 10-14% left. It also drains much quicker from 25% and downward.

Could this be a bug in the latest iOS update?

It seems to only effect some so it could not be a huge bug in the OS but many are reporting the battery gauge is erratic.

so you're saying that it IS an IOS issue?
what kind of issue is this?
and how do i check if it's indeed the problem?

hey don't blame OCD on a specific thing that wasn't there a week ago.
not my fault i'm too tentative on these things.
it's a fact, and i was perfectly satisfied with the battery for a long time.
 
Newtons Apple said:
Why not take it to the Apple store and have them diagnose the problem.

Because-

First, i dont have a legit Applestore, only lame distributors that don't really know anything about a little issue like that.

And besides, its only a week, and i thought this forum might be full of peope who know exactly what im talking about and already checked this issue and came to a conclusion ;)
 
Since this issue has started occurring so suddenly, it is unlikely to be a hardware problem (that is, assuming you are using Apple supplied cables and chargers only). In addition to installing a new app, an existing app that was recently updated and has started behaving unexpectedly since may also be a reason behind this problem.

Could there have been something that changed in relation to the cellular and/or WiFi signals in the places that you frequent? If some signal became weaker for some reason or changed in some other way that could have an impact on how much power your phone would use to find and stay connected to that signal, even while in standby.

i don't think so. i thought this might have been the issue at my work,
but today it was the same at home with my trusty WIFI.

But what about cellular (or do you have that disabled)?

how do you mean? it was all WiFi at home all day long..
besides, i was using cellular many times around heavy usage days,
and until now it was NEVER an issue like this week.
it's now a fact that it's just drains for no apparent reason.

The phone will maintain a connection to the closest cell tower regardless of your use of the phone. If you have a low cell signal at your home, the phone will turn up the transmit power to maintain the connection. You should see a "low signal" indication in your batt. stats though.

Basically if the cellular signal got worse where you are, even if you are on WiFi at the time, that could impact the phone working harder to obtain or maintain the cellular signal (in some sense similar would apply to WiFi as well). Sometimes it's not really that much of a noticeable difference as far as what you are doing, but could be to the phone nonetheless.
 
interesting..
so you people saying that even if i use Wifi connection, the phone stills need good 4G tower?
but i thought part of the purpose was to save also battery life with switching to Wifi :(
