iPhone OS 3.0: Push notifications might be killing your battery

Posted on by

iPhone OS 3.0 brought with it a slew of new functionality, and some hidden gems. copy & paste, extended battery life, and push notifications were the three that piqued my interest most of all. after upgrading, i was happy to find that copy & paste worked well enough, and i actually found improved battery performance post upgrade. life was good. admittedly, i was a little disappointed that apps like AOL Messenger were not ready to go with push notifications right out the gate.

a little less than two weeks ago i noticed that my iPhone 3G was refusing to charge beyond 20%. the main battery indicator displayed 20%, and the indicator in the upper right displayed the “plugged in” battery symbol. definitely a mixed signal.

i decided to wipe the iPhone, do a full restore, and see if this improved things. after doing so, the iPhone accepted a full charge, and the next day we embarked on a trip to San Francisco via Caltrain. a few hours after leaving, and with very little use on the iPhone, the battery displayed 50% charge (and draining quickly). a couple notes on my settings before someone chimes in on with suggestions:

  • brightness is ~30%
  • 3G is off
  • WIFI is off unless i’m in an area with known access
  • push mail is on, but only for exchange. all other accounts are set to fetch

by the time we reached our destination the iPhone was well below 20%, so we decided to make a pit-stop at the apple store for a visit to the genius bar. after a short wait, the apple tech ran some tests on the iPhone, and then promptly replaced it with a new one.

back at home, i upgraded the OS to 3.0, then restored from a backup. things seemed to be going better, in that i could at least charge the iPhone without problems, however the battery drained quicker than i’d remembered prior to 3.0. over the next week, the iPhone’s battery life continued to dwindle in performance, and the mixed signal issues from the first round started up again.

this time i tested the iPhone charging behavior a little more. i noticed that unplugging and replugging the iPhone back in could eventually trigger a charge cycle. so, i left the iPhone on the charger for several hours only to return to find it was completely drained of battery. next, i decided to test different charging scenarios: plugged into a computer, directly plugged into the wall, and using different cables. all of this made no difference.

on the verge of yet another wipe and restore attempt, i happened to notice something that opened up another possibility. i received a push notification from foursquare while charging (with the charge indicator displaying the lightning bolt symbol). after i read the notification, something caught my eye — the lightning bolt in the upper right was now replaced with the “plugged in” symbol. to top it off, the push notification (when the phone was left locked) kept the iPhone’s display on. i monitored this for roughly 10 minutes, and the screen never went back into sleep mode. sure enough, the battery was draining steadily.

it’s completely reasonable to expect push notifications to have some impact on battery life, but this appears to be a bigger functionality issue. i’m not seeing the same behavior with other notifications (like text messages, missed calls, or voicemails). for now, i’m keeping push notifications turned off until the v.3.1 update to the OS drops. of course, this might not be the same for all. i’ve found that some people reporting the opposite case (push mail causing the drain, not push notifications).

i’ve tested the phone for 2 days since removing push notifications, and battery life is back to the “improved” levels from before enabling push notifications. i’ve yet to bump into any of the odd charging state confusions, and i’ve also been able to heavily use the phone while commuting on Caltrain with only a 25% loss of battery (this was unheard of on the 2.0 software).

anyone else experience similar issues?

    wait….Apple replaced the phone!

    • http://cineoctoboo.com/ mario

      yes they did. it was still under warranty.

  • Jeffrey Kaplan

    Exchange, at least on the iPhone, is not push. I don’t know for sure, but I think it’s actually “IMAP-IDLE”. Push itself has little to no effect on the battery life, but IMAP-IDLE keeps the email client open in the background all the time actively monitoring the server for new messages rather than being triggered from a PUSH notice. Further, OS3 added this. OS2.x did not support IMAP-IDLE.

    • http://cineoctoboo.com/ mario

      i wasn’t aware. regardless, even with the addition of IMAP-IDLE in OS 3.0 the battery was stable and even seemed to be improved post release. the trouble began with push notifications turned on, as it seems to interrupt the charging state of the phone whenever a push notification is received.

      thanks for the info!

  • Manuel

    I’ve used Exchange Push Mail & Contacts on my iPhone, and it drains the battery more than push notifications.

    Right now I’m using Mobile Me & push notifications for 6 apps and the battery goes well, I’m not seeing any difference from before.

    • http://cineoctoboo.com/ mario

      push contacts is a big no-no for battery life. i manage contacts by syncing with yahoo! mail contacts, it makes life much easier, and keeps the battery life up.

      the push notification issue might not impact everyone. part of the reason i’m posting this is to get a sense of whether others have noticed the charging state issue. i’m not opposed to returning to the genius bar for another swap, i’d just like to get a feel for whether anyone else has experienced this. thanks!

        Hi, I have the new iPhone 3gs and I’ve noticed my battery life being drained more often than me friends iPhone 3g and I think mine and ur situation is similar… Once I Ty to charge my batter I connect it and the “plugged in” symbol would appear instead of the lightning bolt and it would keep gettin drained instead of recharging to gain power… So I don’t know if it’s my email because I have that active day and night and also a push notification for yahoo messenger???? Not sure I need help too

    What are you using to do the charging? An official Apple cable or something else?

    I’ve seen the “Push Notification stops charging” when my iPhone’s in my Bose SoundDock, but never when connected to my laptop or the official Apple charger.

    • http://cineoctoboo.com/ mario

      in all cases it’s official apple gear (USB and AC adapter) — either plugged into my iMac or directly into an outlet.

    I have recently noticed a similar sort of problem. When my iPhone is completely dead, if I plug it into the wall charger, the red battery symbol and the charging symbol come on the screen and stay on permanently; and the phone won’t charge! I am thinking that the screen uses more power than the wall charger produces.
    Oddly enough, if I plug the phone into a computer it will charge just fine. Also, if the phone is not completely dead, the wall charger works as well, I presume because the screen does not stay on the whole time. I think they have a bug in the 3.0 OS related to what is run while the phone is in the “beginning charging from a dead state”-mode.

    thats weird that they replaced your phone, my phone has a 3 year warranty and when mine went dead they told me i must have ‘dropped it’ even though I have a case on it. So therefore they said it wasn’t ‘under warranty’ all they do is take my money.

    same happened with me when i turned on push notification in ebuddy but when i turned it off the battery life was back to normal………….

    I have experienced the same exact thing. When I turn off push notification the battery lasts a day. With Push on it drains in hours! About 50% of the time the phone would actually heats up going into what I call “accelerated battery drain mode” so I’d turn off Push & restart the phone to try to save the battery. Nice to have it work like a Blackberry but the cost is too great. For now, I will continue to carry both device! Apple wake up.

    I have experienced the same exact thing. When I turn off push notification the battery lasts a day. With Push on it drains in hours! About 50% of the time the phone would actually heats up going into what I call “accelerated battery drain mode” so I’d turn off Push & restart the phone to try to save the battery.

      If you’re under warranty (and purchased from Apple) I definitely recommend that you take it into the Genius Bar. Chances are, this is likely a defective device. It shouldn’t be doing this.
