iPhone 5 battery life [Merged]

DFU restore since it wont launch iBoot. It will do a very clean install on your phone.

OK, so I was too impatient to wait for an answer so I went with a standard restore.

I don't think it has worked, as my iphone dropped from 100% to 96% in under 10 minutes, just playing around with the settings.

I then turned the iphone off and back on, and it showed 100%???

Really think I've got a lemon here, as my first iphone had great battery (wish I'd kept it - returned it because of cosmetic issues that seem insignificant to crap battery!). I remember setting this phone up, and the first thing I thought was how quickly the battery depleted just doing basic stuff.

My network provider (Orange) have been totally unhelpful, so I've booked an appointment with apple tomorrow. Obviously this is a brand new handset so I'm looking for a new, not a referb, replacement. Is this likely to happen?

I'd say that at this point, early in the production process, there are not too many refurbished iPhone 5's out there. When I replaced my first iPhone 5, manufactured week 35, I got another one that had been manufactured week 39. So you'll get a "refurb" but it will be a brand new phone. Although not in a new box.

My battery life is great I think.

4g - ~16 hours
LTE - ~2 hours
Wifi rest of the time
Bluetooth on all the time
~1.5-2hours of talk time
~3-4 hours Bluetooth audio streaming

Dude, are you sure you have the same iPhone 5 as the rest of us?? Bluetooth on all the time and you get that? Insane!
 
I seem to be getting 7 hours usage pretty consistently before I need to charge my phone. Drop 1% every 5-6 minutes on wifi which is nearly on target with apples claim. So it usually gets me through the day, might get one of those icarrier charges though for if I was ever going out somewhere and had my bag with me as there's no way it'd last a day of heavy ish use if I was travelling somewhere.

7h usage and how long standby?
 
8hrs Usage
2 days 3 hours standby

not bad but not heavy use tbh, wifi internet, few texts, twitter etc ....
 
Coming from android i have to say i'm pretty amazed at the battery life i've been getting. When i had the galaxy nexus, i'd generally leave work around 25% remaining. I'd say i use the iphone more (cause it's new) but i'm usually around 70% left when i head for home.

Anything up to 2 days? At 5hr30 usage and 41% with nearly 2 days standby as I haven't used my phone much the past two days because I'm in work. And that's just mostly WiFi browsing, texting and a few phone calls. I could charge it tonight but I'm only out the house tomorrow for about 8 hours and 7 of those are in work so I could probably last the day just checking email and Facebook and texting. Drops about 1-2% overnight and a few % over the few hours I'm in work due to me checking the screen and my emails every few hours.

You should be very pleased with your battery stats then.

Mine drops around 7-9% over night with or without DND-mode on/off.
 
I was curious about my battery draining quickly and have begun some "real world" testing. I used an app called goodplayer to watch some tv shows and found that the iPhone dipped 10% in about 18 minutes consistantly.

I was pretty unimpressed with this quick drop so I loaded up a movie and watched in the stock Video app and I get right over 1 hour per 10% battery which falls in line with the 10 hour on video claim.

I have LTE turned off, 4g on with emails fetching once an hour. My brightness is at 40/45 % and I have some headphones plugged in with the volume set at about 75%. I turned off many features as the phone is just playing video like Bluetooth, Location Services and Siri during this test as well. Figured all I'd really want to be up to date on are incoming emails.

I have a theory that if an app isn't fully optimized for the iPhone 5 yet (which goodplayer is as it plays full screen) or even iOS 6, this could be the cause of the drain on the battery. Stock iOS apps from Apple may have been more rigorously tested and are less taxing on the system as a whole?
 
What do you guys think about mine? I am not very impressed when I look at some of yours, especially those with 1 or 2 days of standby

Just my 2cents here, but for those of you complaining about battery.

1) (esp if you are comparing to iP4) you now have LTE and much faster speeds for dl and ul. It will take more battery. iP4 only had 3g capability and therefor had MUCH better battery life.

2) juicier processer, and brighter screens than the competition amoled screens.

3) The screen is bigger, although still horribly puny imo but that will take more juice.

4) iPhone users tend to use brighter settings on the phone than you really have to (not everyone mind you) but again, this will affect battery.

I figure if you keep background processes closed and if you aren't in LTE areas, to switch your device to 4g only (if you have that option) when you are in weak or non LTE areas you will likely save tonnes of battery.

Unlike the iP4 where you could have wifi on all of the time, with a more powerful device, it might just make the difference to turn it off when you are not either using it, or are out of your usual wifi area. Otherwise it keeps polling.
 
This is mine:

- wifi browsing
- iMessage and messages
- low processor games like temple run
- numerous calls
- some 3G browsing here and there

I will answer your 2 cents because there is so much that you've gotten wrong about this device.

First off, LTE/4G doesn't work in Sweden, or actually any of the nordic countries.

Secondly, Apple clearly advertised the processor being more energy efficient while still being a lot faster than previous versions as the A5 for example.

Screen is 0.3 inches bigger but battery is bigger and stronger.
iPhone 5 battery:: 3.8V - 5.45Wh
iPhone 4S battery:: 3.7V - 5.3Wh

So that doesn't hold up.

About the brightness settings. I haven't heard of anyone with batteryproblems that are still running their brightness over 50%.

I'm not sure why you are defending Apple when they clearly are letting phones with issues out. I know it's hard to understand being a true Apple-fanboy and all myself but they've messed up. And they better solve it soon. Turning this and that off doesn't work.

The iPhone 5 is said to be better than 4/4S at everything. Sadly this isn't the reality for everyone.

What were you doing for the 7 hours though? You can't really compare when everyone does different things. I could match those stats but being in work I don't use my phone as much as if I was off. I'll have about 6 hours usage and 15-20% battery with 3 days standby when I get home tonight but when I've used my phone constantly all day I can get 8-9 hours usage before it gets to 1%.
 
Light cellular usage less than 100mb and about an hour of music. Just sad. This is one setup from new as well. Waiting for 6.0.1 before I swap. My wife had around 6hrs usage with 39% left and was complaining that it wasn't as good as her 4. I showed her mine and laughed.

I'm getting 4-6 hours 4 is heavy usage and 6 light. Coming from the iPhone 4 I'm disappointed. I now have 76% going into my first class of the day. Make that 75 now. With my iPhone 4 is have about 92%

It seems like Verizon LTE guzzles the juice
 
OK, so I'm off to the Apple store tonight.

My battery life is really bad. I'm getting about 4 hours on wifi, and just using it today I'm seeing it drop 10% on 3G in just 18 mins. This is after a restore, and then a DFU restore. I have also given the battery a few cycles. I really don't see there is anything else that I can do to improve it.

Any advice how to explain it all to the genuis so that he doesn't try and fob me off with advice like turning off wifi and push etc, or making me go away and do aother restore? It's a long journey for me to the store, and I want to make sure I'm coming away with a replacement phone. I'm not looking to pull a scam here - I have a genuine case of a rubbish battery and I deserve a replacement.
 
By the way, if I want to do a full charge from 1% to 100%, and I plug in the phone but then very briefly unplug it, before I plug it back in - will this effect the battery? Will it stop it being a full cycle charge as it was interupted - if only for a couple of seconds?
 
RESTORE your iphone, worked with mine, now I'm getting 10-13h usage on wifi.
