    "Your phone gets warm when you go to low signal locations because the phone must increase its output power to maintain a connection. By a lot. When you have 5 bars the phone uses its lowest transmitter power setting, which is probably around 50 milliwatts (50 mw). When it only has 1 bar it must change to 600 mw, over 10 times higher. Which means the battery drain will be 10 times higher, so the battery gets warmer. Add to this the fact that the transmitter is not 100% efficient, so the transmitter chip also gets hotter.

     

    Your phone gets warmer using cellular for either voice or data for the same reason. WiFi uses 30 mw. Cellular uses a minimum of 50 mw, and will use more as the distance from the tower inceases."

     

    I can live with this fact, but is it normal for my battery to drop 2 - 3% everytime I make a call?  My daily usage is as follows:

    Charge my phone at 9 or 10pm at night, pull it out 12am or 1am(no apps running)

    Still 100% by 6am

    Make a call for about 30sec at 630am drops 1%

    By 9am drops to 89 - 90% after some light viber and sms messages

    If I have a slow morning, battery would be around 65% by lunch.  If hectic morning, 49% by lunch

    By 3pm it will be around 30 - 35%

    If I dont get or make any calls, then I will be lucky enough to play some games before I charge it again at night.

     

    btw, I've tried every solution in the forums except DFU restore and taking out the sim card.  It did help some, but not enough.  Like I said, my battery before is around 53% by 10pm, which will get me through another day without charging.

    My 4s & 5 were running 6.0.1 and I refused to update until recently until the "exchange bug" was fixed.  I used 2 Exchange account with Active Sync Contacts.  On 6.0.1, it was hard for the phone to die throughout my work day.  I run Daylite 4 Touch, Zendesk, Freshbooks, Spotify and Google Chrome & Maps, GPS, Bluetooth all day without any problems with battery drain.  I would be at ~50% getting into bed that night.

     

    On 6.1.2, the very first day, phone was in the red by the afternoon.  This was my iphone 5.  My colleague is using a 4s and the exact same thing happened.  It continues to happen regardless of option turned on and off etc.  I never turned and off, nor reset my phone running 6.0.1, it just worked fine. 

     

    We are Apple developers and now are running 6.1.3 Beta 2.  Im sad to report that nothing has changed for either phone.  I have faith they will fix the issues, no doubt, just not too fun at the moment.

    You were right to wait for THE Exchange bug to be fixed; it was a biggie (not the first, BTW; there have been other major Exchange issues over the years). The problem is there are lots of Exchange bugs, and most of them are embedded in the ActiveSync protocol and have been around forever. The most common one is the phone loses its connection to the Exchange server and opens a new connection. But any messages queued on the old one are not purged, they just keep failing (and using battery). I once had our Exchange admin look at my phone from the server end - there were 10 open connections, only one active. So whenever I experience a sudden increase in battery consumption the first thing I do is turn off the Exchange account in Settings, reboot the phone, and turn the Exchange account back on. This usually fixes it. Even with 6.1.1 (I haven't had a problem with 6.1.2 yet).

     

    I suspect that most battery drain issues that occur right after an upgrade are caused by queued messages on connections that are stale because the upgrade process interrupted them. This would explain why more people have a battery problem right after an upgrade, but not everyone, because not everyone had ActiveSync activity going on at the time they clicked the Upgrade button. I also believe the same thing can happen with other apps - I'm suspicious of Facebook, for example.

     

    I've also discovered that the new Google Maps continues to run in background after you have asked it for directions, I guess so the next time you open it the display is up to date. But this uses battery pretty fast also.

    When you ae making a call with a strong signal it is normal for the battery to drop 1% for every 4 to 5 minutes of talk time (8 hours or 480 minutes/100)  If the signal is weaker it will drop more quickly. With a very weak signal it may drop 1% per minute.

     

    Note also that when you have a weak signal the battery will drain faster even when the phone is idle, because it "checks in" with the cellular network every few minutes so the network knows where to find you when you get a call.

    • Apple does not read these forums, so your message to Apple in your post is wasted
    • Apple is not going to fix it (see the post from @Macdev_Fighter)
    • Replacing the phone won't fix it if you restore your backup; only if you set it up as a new phone. But you could do that with your current phone
    • You can fix it if you want to, or you can buy someone else's phone, and then discover it will not give you the battery life you expect either.

    Because Apple says they don't. It's likely that some Apple employees read the forum as users of Apple products, and there are moderators whose sole job is to maintain order, but this is not a forum for communicating with Apple. You can read the Terms of Use for details: https://discussions.apple.com/static/apple/tutorial/tou.html

     

    The point of the forum is so users can help other users. That is its only purpose. It is not a blog; it is not a place to complain; it is not a place to attack or threaten Apple.

    I'm sorry that I've decided on the iphone5!!!!

    @Lawrence Finch

     

    I finally caved after finding no solution to my battery drain and did a restore as new phone, then restored my backup.

     

    And here are my results.

     

    I restored as new, ran phone for a few hours, normal battery drain.

    Then restored my backup, waited a few hours for everything to "sync" in. Then tested, seemed good.

     

    Today after being off the charger for more than 3 hours and moderate use, my battery has only dropped 2 %. WAY better than it was.

     

    So I will say my issue is fixed.

     

    Thanks!

    Right. Out of the frying pan, into the fire. Enjoy your Samsung, but be aware of what you are getting into:

    You could also follow the example in the post immediately below yours and fix the problem. But I guess if you fixed it you would lose your excuse for ranting.
