Does the iPhone 4S Battery Life Fall Short of Expectations?

By , Oct 17, 2011

The iPhone 4S is better than its predecessor in several ways. It has a faster processor, better camera, and of course the popular new Siri feature. And apparently, all of these upgraded components have affected the new iPhone’s battery life.

Reports have been pouring in over the last few days regarding the new handset’s poor battery performance. Some folks believe that the device’s battery isn’t living up to the expectations Apple set. So iLounge decided to do some investigating…

In the midst of its exhaustive 7 page review, iLounge talks about the iPhone 4S’ battery life. The site performed several tests on multiple handsets (including the iPhone 4), and the results might just surprise you.

In the end, it appears that the iPhone 4S’ battery life really depends on your individual usage. Here is what iLounge concluded from its experiment:

“If you spend much of your day near a Wi-Fi network and only rely upon the iPhone 4S for web browsing and phone calling, you won’t notice a major difference—unless you’re thinking of switching to Sprint, in which case we’d be a little concerned. Similarly, if you use 3G data, plan to record or play videos, or want to listen to hours of audio during the day, you can expect greater battery drain from the iPhone 4S.”

It’s not surprising that the iPhone 4S uses more power while shooting movies or surfing the web on 3G, considering both of those areas received major upgrades on this year’s handset (8MP 1080p, HSPA+). But it’s interesting that none of the devices reached the projected 6 hour mark for web browsing on 3G.

If you’re looking for a way to squeeze a little more juice out of your new iPhone’s battery, you might try checking out some of these battery-saving tips. Apple also has a support page setup with some useful pointers.

How is your iPhone 4S battery compared to your previous handset?

      Restoring my phone “as new iPhone” worked like a charm

      Corrected. Thanks!

    You guys need to take Siri into account here… its a battery drain, especially “raise to speak”

    • http://www.idownloadblog.com Cody

      That’s a very good point. With the raise to speak feature, the iPhone’s proximity sensor is constantly active.

      • v00v

        can you disable it tho?
        if you could disable it how much battery life can you save?

      • http://trenpennrepairs.com Jj

        Settings general Siri. Them toggle off raise to speak

    I’m still waiting for December when my contract ends, for now I’m just enjoying my jailbroken iOS 5 on my iPod Touch 4.

    Infact I used reader to read this article.

    If you’re experiencing severe battery drain on a 4S with minimal use, do a Reset All (Settings > General > Reset > Reset All Settings) and it should fix it. Has worked for me and several twitter followers.

  • iGirl_in_SC

    I just turned off the stock widget and also went to Settings > Location services and at the bottom of the page I disabled some System Services. Still I get much more battery life than my previous 3GS.

  • Jason

    It’s fine for me, same as my 4.

  • Fm

    How much of the drain has to do with the fact people are constantly playing with their new phones.

    • Masters

      Irregardless of how much they’re using it, they should still get a certain amount of usage.

      • RilesPro

        Irregardless is not a word unless you are front he hood and use double negatives freely. How’s school going bud?

        I use my 4S from almost the time I wake until it dies. Been losing about 12% per hour on wifi dead in 6 to 8 hours.

        The battery gets MUCH BETTER over time (about 2 weeks). I noticed this with my iPhone 4 and it was a big difference. No one has had theirs that long so they don’t know yet.

      • Masters

        That’s great when u go to correct someone and u can’t type and make correct words yourself! HAAA!!! I sure hope u felt good while writing that cause I know I sure enjoyed it. “irregardless” may not be accepted as a standard defined word, but people get the point. In my defense I have listened too much to Johnjay& Rich talk show and the word has been burned into my head(not a good excuse I know).

    According to apple website:

    iPhone 4S – Standby time: Up to 200 hours
    iPhone 4 – Standby time: Up to 300 hours

    and

    Iphone 4S – Internet use: Up to 9 hours on Wi-Fi
    Iphone 4 – Internet use: Up to 10 hours on Wi-Fi

  • ic0dex

    I use “Rise to Speak” and “Siri” and WiFi and 3G, my iPhone 4S lasts me the entire day. Dim your screen a bit and that will save you some battery life.

  • Omar

    I remember when I first got my iPhone 4, it had the same issue. A few battery cycles and a week later, the battery was amazing.

  • Xepptizz

    “But it’s interesting that none of the devices reached the projected 6 hour mark for web browsing on 3G.”

    That’s not true, the iPhone 4 bar is over halfway the middle of the 300 and 450 mark, which is 375, which is more than 6 hours.

  • TracieT

    Cycled my battery once so far, tuned off anything I don’t use. Dimmed my screen slightly and use wi fi at work and home. At 5 pm my battery was still 81%. Not using Siri a lot yet though.

  • albioni

    All of you should give up ur iphones, and get a Samsung galaxy s2. Battery lasts for couple of days, better screen, better camera, much smoother, faster, and beautiful. Oh and for the same price :) if apple made this device would charge at least $1000 and you Olso probably had to wait a month in line lol. Please don’t be such fools give a test to other devices old

  • Ethos

    poor 4s owners haha hy u buyin such crap

  • http://www.YouTube.com/user/MRTWIT21 Mrtwit21

    Pow viva iphone4
    Ive had mine since release day and the battery life is still better than the ip4s hahaha

  • RC

    Yes, the battery life of the iPhone 4s is very bad, I have a 12% drain per hour, which isn’t acceptable. My iPhone 4 had a 5% drain per hour…before I updated it to iOS 5. Now it has a 10% power drain per hour, so I think iOS 5 is actually to blame, not necessarily the iPhone 4 or 4s.

    A short comment regarding the Samsung Galaxy S2 somebody mentioned: Battery life, I’m using a custom ROM mod with various battery life enhancements, is good but not really that good. Battery life drain is aprox. 5-6% per hour, slightly worse than my iPhone 4 with iOS 4.3.5. So please keep it real people and don’t make false claims. The only way the Galaxy S2 battery life could last two days is if you turn off all data services and keep the display at 20-30% brightness, which would be kind of weird.

    • kokhean

      5% per hour? I think something’s wrong with your iPhone 4. My battery at the maximum decreases about 2% per hour. Most of the time, the percentage stays the same. And I am using an iPhone 3GS, with data on, notifications on, location service on and I keep Mail and WhatsApp open all the time. And also, it is jailbroken on iOS 4.3.3 and I have installed a lot of tweaks, including LockInfo.

  • Erik

    Yeah, I’d agree so far it looks like it is just slightly less than my iphone 4 with the same usage patterns. But by no means anything to be upset over. I’m around a charger nearly all day if I need it so I am unaffected by it.

  • http://Yahoo Elvis

    I received a iPhone 4 and a 4s from sprint. The iPhone 4 drained quick for the first 2 days but works great now. The 4s sucks for battery life, now I find out sprint is the problem. It’s there 3G network , I think they jumped the gun at apple and did not test the sprint network. I had a EVO 3d and the battery life on that sucked too.

  • Niniani

    I thought I was also a victim of this battery problem and even redone my iphone as a new device (previously just started from backup of my iphone 4 ) But I have just discovered that for me the problem is not the battery but the indicator ! My phone said its on 1% battery power and I have been skyping for 15min and now playing settlers for over 20 min while my phone still claims Ive got 1 % left of battery. Somehow it cant calculate properly really how long its got left. Perhaps this is because I only had it for 2 days and didn’t allow it to run down until it switched itself off during the first charge cycle?

  • Jamie P

    FWIW, try an app called Battery Boost Magic. I’m really surprised, but it worked for me. I used to need to charge by around 6pm…it’s now 9pm and I still have 57% battery left. I don’t know how it’s helping, but I really does seem to.

    I just changed from a HTC to Iphone 4s, I have mobile networks and 3G off only wifi allowed, today I’ve had no phone calls but about 8 text messages and the phone hasn’t lasted the day, to me thats completely unacceptable!!

  • Andy

    My iPhone 4s battery life is shocking I hardly use it for calls or messages anymore because it doesn’t even last the day where my old 3G lasted 2/3days under the same conditions, and with the exact same apps and usage, is there a warrantee on the batteries or what can I do to get this sorted out besides getting a different brand of phone?
