Battery life

Northernist said:
I'm not sure how Android manages battery but have you ever noticed that when you're connected to WiFi on the iPhone, sometimes when you unlock your phone it switches really quickly from 3G/LTE to the WiFi signal bars? The reasoning behind that is because mobile data is better at conserving power when on standby, and WiFi is better at conserving power when in use.

I haven't used Android in 3 years or so (last Android device I had was a Droid X.. Thing was indestructible) but I know my battery life has always been better on iOS than Android. I'm no expert on the more modern builds, so this could have changed by now though.

thank you for this. i kept wondering why it kept switching when i would unlock my iPhone.
 
Weird combination considering earlier today my phone had died in 3 hours of light usage

Complaining? No but it could be a glitch

I can attest that resetting all settings will fix battery life and keep your data. My phone would hardly last a few hours under iOS 7 beta.

I will know more though out the day, but this seems to be the fix

I just reset all settings on my iPhone 4S for the first time. Hopefully I see an improvement in mine too. Not that the battery life on mine is bad. Generally, mine drains at 10% per hour on Wifi and on 3G it's like 15%. What I very much often do on my phone are using Facebook, Instagram, Twitter, Flipboard, Whatsapp, Viber, listen to music on Track 8 app, watch YouTube videos on Jasmine app, surf the web using Mercury app and the default mail app. I do play games occasionally.

I updated straight to iOS 7 beta without restoring my phone first. Initially, the battery life was really bad. I think it went from 100% to near 0% in less than 3 hours. After I totally disabled Background App Refresh and Automatic Downloads (in iTunes and App Stores), the battery drain improved a lot. By the way, I've always had nearly all my locations services for apps turned on. I read that enabling "Reduce Motion" would also improve battery, but I'm gonna pass on that for now as I'm just smitten by the parallax effect on my lockscreen wallpaper. :D

Regarding System Services under Location Services, may I know what most of you have turned on? For that, the ones that I have turned on are only Compass Calibration, Mobile Network Search and Wi-Fi Networking. Thanks! :)
 
I have done more surfing (moderate) since I first posted a picture this morning, as well as continuing to listen to iTunes Radio. Also did a speed test. I turned on Location Services for a 20 - 30 minutes, but turned it back off due to it draining my battery. I have also had several apps running at the same time.



Just plugged the phone back in. It is not the same battery life as iOS 6, since I had a few features turned off. However, I don't think it is far off.

"Have you had any issues with battery life with your iPhone 5 or 4S? Did you make a clean install and then updated your iOS? Make sure that you make a backup and then wipe date."

This is taken from an article. What does it mean? Doing a clean install of iOS6 and than updating your iOS 7 beta as a clean install?

Apparently it helps batt life.


This was taken from another article:

"We performed a backup of our iPhone 4S and iPhone 5, and then we performed a clean install of iOS 6 by entering iTunes in DFU Mode. This is achieved by holding down the Sleep/Wake button and Home button, then once the Apple logo appears you keep hold of the Home button only until iTunes pops up with a message about an iPhone in recovery mode.

"Once we installed a fresh copy of iOS 6, then we install iOS 7 beta and after this the settings and data were restored from a backup. It is worth noting if you can't downgrade to iOS 6 from iOS 7, but you need to have a backup of your phone in iTunes with iOS 6."

my phone has been running hot the past few days. I JUST turned off automatic app update and it cooled right down.

So Summary:
- App refresh: Off
- Reduce Motion: On
- Automatic update: Off
- Location Services: Off
- Reset All Settings
- Reset Network settings

Will report soon, but right now, my iPhone 5 is ice cold for once!

Report: Battery life sucked even with all that off...
So I restored iOS7 and only loaded back text messages.

Awesome battery life thus far.

Currently at: 60%
Usage: 4 hours, 39 minutes
Standby: 5 hours, 40 minutes

Just enabled 'Reduce Motion' on my iPhone 4S. Hmm ... Hopefully it'll further help improve the battery life.
 
I fresh installed iOS 6 then immediately fresh installed iOS 7 and my batt is at 74% within 3 hours, which I say isn't bad. I had a 48 min call and burnt 12%, and light usage! We shall see I will report tomorrow
 
Definitely happy with my battery life, ever since I clean installed iOS6 and iOS 7...respectively. I hope it doesnt change :) 6 hours since last charge and @ 55%
 
The issue with iOS7 is the auto brightness, it's broken. All you have to do to fix the battery issue is turn off auto brightness and I also turned off background refresh setting. This fixed my iPhones battery life to where it's almost as good as before I updated, It lasted a full day before updating. Hope this fixes yours. Let me know
 
I was having this issue also. I could almost watch my battery drain no matter what I did, or which settings I turned off. I finally gave up and let it drain all the way until it powered off. Ever since doing that, my battery life has improved. It's still not amazing but It's a lot better then before.
 
Just did a Reset Network Settings and immediately the heating issue vanished. I'd forgotten how cold my 5 used to be!
