iPhone 5 battery life is way worse than iPhone 4

I just got an iphone 5 and I restored a backup from my iPhone 4 so I have the same settings. But the iphone 5 drains way faster than my two year old very well used iPhone 4 which is running 5.1.1. Is it because of IOS 6? Just leaving it sitting overnight lost about half the battery. My iPhone 4 hardly uses any battery while it sits overnight.


Or do I have a bad battery on my new phone?

So I've had my first iPhone 5 for 5 months before the lock button started failing and the battery life on that lasted me somewhere between 4.5 and 5 hours. I've gone through 4 replacement phones since then but now my latest replacement has a battery life upwards of 6 hours with the same usage. Perhaps I was given a battery defective phone from the start but I've noticed a pretty significant difference in battery life here.

I've been following this discussion for a while. Most of the people reading this thread are presumably experiencing poor battery performance, either compared to the iPhone 4/4S or compared to other phones, or just general frustration from not being able to go an entire day without recharging.


Maybe I'm just lucky.....or maybe it's partly because I don't usually spend a ton of time on voice calls (normally less than an hour a day), but I feel like I'm getting pretty decent battery performance from my iPhone 5, pretty close to its stated specs. I'm running iOS 6.1.2, and it appears that many people felt that 6.1.3 really affected their battery life (latest is 6.1.4, which included a speakerphone upgrade), so maybe that's another factor in my favor.


I think it would be interesting for other people to weigh in with usage stats for their phone, including some basics about their usage habits, iOS version, and general settings (push vs. fetch email, average amount of talk time, etc.)


On my best days, I get at least 9 hours of usage and about 30 hours of standby time. On days where I spend more than an hour on voice calls and/or use a lot of video, that drops to around 7.5 or 8 hours of usage and around 20-24 hours standby. From what I gather, my experience is a lot better than what some of you are getting. But even on the heaviest days of use, I can't imagine ever having a problem easily making it to bedtime if I started with a full charge that morning. I fetch email every 30 minutes, and I have Location Services turned off for everything except map apps, Safari, Siri, Find My Phone, and Google. I keep push on for things like Facebook. Most of my data usage is via WiFi, so that probably helps some...maybe a lot.


Curious to hear what other folks are getting....surely I'm not the only one satisfied with my battery life???


People that are reporting like 3-4 hours of usage....are you running constant video via cellular or spending 4+ hours on voice calls?

My first iPhone 5 I got roughly 3-4.5 hours just by having the screen on doing some web surfing, messaging, and facebook, (no videos or music). Now on my 5th iPhone 5 and the battery here, doing the exact same thing, can last more than 6 hours. This is with LTE on by the way. I have email to manual every 1 hour and turned off everything in iCloud.

I've had my Iphone 5 32 GB for 10 months now and at first my battery use to die in 5 hours or 6 max. Now that i've updated to IOS 6.1.4, My battery last up to 30 hours on standy and usage same as dmilazzo 7.5 - 8 hours of usage and thats by using phone, text, watching videos, surfing, taking pictures, twitter, games, but i have everything disabled i.e e mails. I only do manual everything also i always double tap on my home button to exit programmes etc. I always let my battery die out till it turns off no matter what. I recommend upgrading to IOS 6.1.4 for everyone. What i find weird is that 3 weeks ago i was getting usgage of 9 +? Ermmm so i did reset (quick one) going into setting then reset all setting, did it 8 times in a row and it seem to be helping but at the same time i feel like if you reset all settings it just makes it worse or sometimes better? My point is apple products are unreliable sometimes which isnt so good because i use to have an andriod phone before my apple but over all im happy it could of been worse and greatful for that. I'm just waiting for the new iphone 6 not iphone 5S but i heard they might bring out two phones this time. All i know for sure is next year their will be a bigger screen iphone and thats what im after. I guess we all have to be patience and its all about 2014 next year 😁

The batterry of iphone 5 is really *****!!!!!!!

I just recieved my iphone 5 four days ago, I am apple lover some might said and almost collect all the gadgets so far, never had problem with battery, infact the battery usally was the high points of those products, But battery life of the iphone is really poor comparing to other product , I AM NOT REALLY SATISFIED , apple crews should be really ashamed of this product, all of the setting was of last night such as wifi, push emails and ... Still battery drains very fast with just normal using,

I'm stil on a dinosaur iphone 4 but had a drastic battery life reduction on ios 6.1.2. I asked Apple why this was and they said that it was because the latest ios update had 'overloaded' it. Nice way of saying buy a new one. However I was suspicious that the Facebook app had something to do with this because this was the main thing that had ground to an absolute standstill so I deleted it, and hey presto my battery life has doubled...back to normal. Even with the app closed it seemed to be affecting it. I now use Facebook mobile which works at normal speed (and with far fewer adverts). Worth a go on the iphone 5 perhaps?

I bought this new iphone5 four days ago and I cannot run it at least for 6 hrs. I contacted (3 times) Apple technical support and non of the technical advisors addressed the problem and collected my phone data for analysis.

As they couldn't work out the exact reason for the issue they passed the problem (technical support phone call ) to a senior technical adviser called Rich. From the beginning his intention was to get rid of the call and he admitted that 6 hrs is normal battery time for iphone 5. This should be in recording with apple under (

my case number 471073471.)

I argued about this at length as the iphone technical spec at http://www.apple.com/au/iphone/specs.html states,


  • Talk time: Up to 8 hours on 3G
  • Standby time: Up to 225 hours
  • Internet use: Up to 8 hours on 3G; up to 10 hours on Wi-Fi
  • Video playback: Up to 10 hours
  • Audio playback: Up to 40 hours

My phone was on standby with 10 mints of calls and reached 10% battery level with 6 hours.

I challenged him to answer the question and ask him to verify all the data I have already sent from my phone.

This so called senior tecnical advisor has no idea about customer relations or any technical knowledge about the phone. Or he may already know the problem with iphone 5. Unfortunately, he hanged up the line and this was terrible experience for me (as Apple being a reputed company) and I wonder why Apple employ this type of stupid people to handle customers technical problems.

Shame on you apple and cutomer service.


I had to ring them again to get the problem resolved. I am in contact with another senior technical advisor and he asked me to restore the ios and promised me to be back with me again ( I am not sure this would work).

Lets see how it goes.

Note it says 'up to' A lot depends on what you have switched on notification wise, if you use 3G or 4G your signal strength etc. Car manufactures MPG are the same, they are under idea conditions, this never relates in the real world, some get more some get less. Same with Broad band speeds, its up to...nothing is precise. 6 hours is not bad if you are using it all the time, not if its just sitting there of course. I get about 6-7 hours over 3-4 days useage. Apple CS has always been exceptional as far as I have been concerened, your milage may vary but attitude goes along way. 😉
