ios 8.3 battery life

i've downgraded to 8.2 after battery issues as described abovew with 8.3, but still no solution, problem stays

iphone 4S

see also Re: iOS 8.3 battery drains very fast

so all you had to do was remove the FB app?

i've done that too in one of my attempts, but no sollution whatsoever.

downgraded back to 8.2, but problem remains, although drainage is a bit less 25%/ 3.5h

i've ran out of solutions......

Hi Blackball,

Removing FB helped A LOT, but it hasn't solved the problem completely. With FB gone, I can do basic activities (bluetooth calls, texting, email, safari, even use maps) and still have ~80% battery by noon. In those cases, usage time is less than standby time.

I'm finding that the phone runs down (usage = standby) when I'm in areas with sketchy cell signal. There are some known 1-bar zones at work, and when I've spent time in those rooms, my phone drops from 75% to 25% in the course of 2h. Next time, I'll plan on turning off cell data in those areas to see if it helps. If not, I'll try airplane mode.

I'm seeing a Genius this afternoon, and will post any solutions that they offer.

hey,

i've now restored 8.3 using itunes ( i think that i used the iphone the first time ) because ive read that this could also be an issue.

i'm now charging again till 100%, everything else left the same.

last thing i can do is change the battery when the problem still isn't solved, but thats the last thing i can think of.

if still no solution, i can only hope that the next upgrade will handle this issue.

still find it very strange that several other 4S-users i know don't have any problems at all.

So at the Apple Store they ran some diagnostics that showed there were various iOS8.3 processes that were hanging in the background, consuming battery life. Separately, there was a problem within iCloud. They recommended backing up to iTunes, then doing a factory reset/set up as new phone. They noted that it may not be a fix - the firmware was updated with iOS8.3, thus a factory reset might still have the same software issues. They also noted that a factory reset meant losing all my iMessages, voicemails, and other important data ... hearing this was particularly difficult, as I would lose notes/VMs from friends/family who passed away. There's apparently no easy way to archive texts with iOS8.3.; you could do this with some 3rd party apps in iOS8.2.

The easiest fix may be to do a data transfer to a hand-me-down 5S, and keep the 4S on standby until iOS8.3 gets patched.

I guess the only piece of good news is that the SF Apple Store is seeing LOTS of people come in with issues after the upgrade, so hopefully there will be a patch soon.

One thing that has been killing my battery all week is that I have been at work in a cellular service "dead zone" office all week. The Battery Usage shows that most of the battery usage has been searching for cell service. Today, I was out on the golf course and running Golf Logix (a golf GPS and scorekeeping app) for a 5 hour golf round, totaling 9 hours off the charger, and came home with about 70% of my battery left. There were no cellular service problems outdoors.

I'm still not sure what caused the episode of rampant battery rundown and iPhone heating up Monday evening, since I had access to cell service then, but I did a "reset all" as soon as I got home and haven't had one of those episodes since. I have also turned off lots of functions such as mail Push, Location Services, automatic updates, background effects, etc. to try to curtail battery usage. I'd love to be able to have all these goodies, but need the battery more.

Still, awaiting a fix from Apple!!

Hi GreyCivic

i think that your "Diagnostic and usage" settings is set to Automatically send

you can check it out , go too settings , privacy and diagnostic and usage,

See if that's help

Yeah, something is definitely wrong if the battery runs down when your not even using the phone at at all.

That's one problem I don't have with my iPhone 6 Plus. If I don't use my phone at all, the battery doesn't drain at all. It only starts draining fast when I'm browsing the Internet on Safari and by watching YouTube videos.

Updated to ios 8.3 .. Hard reset .. Battery percentage jump issue looked solved.. Bt sometime it jumps 2% ... Nt always though bt still a prob somewhere

battery charging so fastly.. 80% charged in just 30-40 mins.. N loosing so fast as well.. Battery life just bad

after some days of usage.. Battery perc prob again comes in picture.. Charged iphone with apple charger.. it was 77%.. I plugged it in usb port for transfer.. Iphone showed 86% .. I was shocked .. So i removed it frm usb port n did soft reset.. Battery meter 90%

what the **** was that apple??

after ol that .. I was using my iphone .. Did a soft reset again as well

today i charged my iphone to 94%.. N unplugged it.. N checked battery usage in settings after an hr.. It was showing 27 mins usage n 3 mins idle after full charge... Bt no full charge in last week... Y iphone showing it ...

one more thing.. Just using safari to write this review.. N battery dropped from 94 to 86 in just 5 mins .. For just typing....

what the **** is this happening... Did full install of ios 8.3 ...

BAttery never remained same after ios 7

going worse n worse

my battery was the same after installing the new update. I contacted Apple support and they said it might be because I did the update over wifi instead of through iTunes. I backed up my phone, reset it to factory settings and did a restore and now the battery is back to normal. Hope this helps

Depends which product you have. Certainly for legacy products it would seem wise to wait until iOS8 is confirmed to be stable and fit for purpose on older platforms/hardware.

I observe my phone for a week and found the culprit of my iphone 5s , only last 5 hour when 3g on

the main is SAFARI yes, when im browse a bit then i close it in multitasking, the app still run in backgroud

and after about 2 hours ,when i open the battery usage and i found safari 30% , it's been idle for long . believe there;s no updating and downloading

and yesterday i switch to chrome , do a much more browsing , and keep it for 3 hour, chrome only consume 9% .

the other villain is motion tracker , and background app refresh.

now my phone can last up to 8 hours in normal while 3g is on.

still not good enough coz apple claim 3g talkttime usage is 10 hours, which is for me that's totally impossible to happen.

In my case, finallly it was helpful, to reset my iPhone with iTunes with a fresh iOS8.3, and not restored my old backup.

It seems something was damaged in my backup which was also transfered then from my iphone 6 to the 6+.

It was not nice, to setup completely new my iphone, but now it works fine for 2-3 days with iOS 8.3.

My case:

I have been happy iPhone 5S owner for my own iPhone, no battery problems, nothing. I have even updated it via Wi-Fi to 8.3 without iTunes and everything was fine.

So happens to be, I needed to buy phone for my girlfriend (this account) because of Android fails with battery etc (which she got earlier).

Bought used iPhone 5S with 8.2 - and I totally found out that battery without SIM and Wi-Fi etc is dropping % like crazy. 100% charged goes to 30-40% in morning even without SIM etc...

At the beginning I thought maybe it's some kind of software bug that phone tries to find coverage even without SIM card (which would be really bad software code) but no, even with SIM card I had the same experience.

Updated to 8.3 using iTunes on OS X Yosemite - of course nothing changed.

Then I thought probably battery is totally wasted of bad phone usage and ordered new one, replaced. Almost nothing changed, so here I started to Google. What I find out, that I'm not alone in this boat, there are whole a lot of iPhone users who struggle with this problem... Googled some more, turned off different settings - tried out almost everything. Nothing... Tried out even restoring from clear, hoping that earlier user did bad restore or something like that - nothing.

So here I'm starting to get from Apple fan boy, to disappointed user... Saying to GF that iPhone is way to go, no problems - "it just works", forget problems with quitting using Android... Yeah, right.

Let's hope I can find how to fix this one, or Apple investigates this one to find out how phone without SIM can eat battery in idle so fast and push some ASAP update...

I have an iPhone 5S and had no issues before isntalling the update. I played my games, read books, ran other apps.

Ever since the update my battery drains at twice or three-times the speed, the phone will restart sporadically on its own. So I'd say don't do it.
