Good Day All,

I Love my iPhone 3G but use it conservatively. I've installed the BatteryLog App and have gone an entire week on one charge. Two nights ago, I installed the 2.2.1 update and fully charged the phone overnight. When I went to bed last night I still had 80% power. This morning when I got up and went to use my phone, I had the red low battery screen. I've never experienced this type of performance from my iPhone ever.

Please note: I'm a retired U.S. Navy Submarine Radioman who paid attention when learning about the proper care and feeding of submarine batteries. This is one of the reasons why I love the BatteryLog App. It reminds me of my Submarine days taking and reading the logs.

Anyone else experiencing degraded battery performance after installing update 2.2.1?

    Hi there,

    I have noticed a degradation of battery life since the 2.2.1 update.

    My phone was on around 80% last night, this morning it was off due to the battery being dead. I nearly missed getting up in time for work.

    I charged the battery to full at the office today, and now, about 4-5 hours later it's on 45%.

    I think we need another update, and soon!

    Pardon me if my memory is playing tricks on me, but didn't we hear the same comments just after 2.2? If I remember right, after a few resets or allowing the battery to power off at minimum, the levels all came back to normal. Anyone else remember this? No?

    I never had such a problem before, I will try to reset the phone and also allow it to drain fully and see if that improves the situation. Thanks for the tip.

    My 2.2 works really well so I have not updated to 2.2.1 yet - waiting to see how things shake out.

    That being said, I would perform an iPhone reset (p. 35 of the manual) followed by fully discharging and fully recharging the battery to reset the meter. Apple recommends this discharge/recharge about once per month to "keep the electrons moving"... http://www.apple.com/batteries/iphone.html

    That fixed it for me. Drained the batter and recharged it as well as rebooted. Now battery drainage seems back to normal.

    Thanks W9FIF.

    Just for grins, what's this battery log of which you speak? I just "googled" the ap store with no find.

    Thanks!

    Same problem began for me after installing the software update 2.2.1.

    I did the reset as well as letting it run all the way down and charging it back to 100%. But the problem persists. I charged it overnight and the charge level looked fine until mid-afternoon when it drops to the red "low battery" level.

    It really seems like the update is the culprit since I didn't have this problem before the update - and my usage hasn't changed.

    Any other ideas?

    Having the battery problem since 2.2.1 as well. Will try suggested fixes. I had never even seen the red low battery indication before, now I've seen it two days in a row!

    By 'reset' do you mean a reboot?

    I'm having the same problem after the 2.2.1 update. Just did the battery drain bit, so we'll see...
