MacBook Pro Battery 'Service Battery' after Snow Upgrade

I have a macbook pro4,1 and am experiencing the same thing. Poor battery performance, "service battery" indication, and only 79 cycles on a battery that worked well under leopard.

There is obviously a serious bug in SL. I went through to Apple Care and when the pointed out my MBP was out of warranty I told them that I wanted it fixed under the SL warranty. They bought that and opened up a case. Suggest everybody else does the same thing. I don't want to roll back, don't want to boot into 64 bit and I don't want to buy a new battery - which doesn't guarantee fixing the problem anyway. I just want the **** thing to work like it says on the tin. Use Twitter, Facebook and anything else to put people off upgrading by spreading the link to this thread. If this doesn't get sorted I'm starting snowleopardkilledmymacbookpro.com!

Add another MBP killed by the white cat.. How can apple not say there is a serious issue with this? My mbp lasts 20 mins and dies.

Even though my MacBook Pro is shutting down at around 78% battery full now, the little lights on the battery show 4/5 lit. So the battery knows it has that capacity, but something in my MBP doesn't.

Just out of interest here are my battery stats...

Sadly, same issue here. After upgrading to 10.6 my battery lasts about 4 minutes max. It went through 106 cycles. It would hold a solid 1:30hr charge prior to upgrade.

New system software is the only culprit here. I uninstalled 10.6 and battery functioned as it had previously.

Update:
Seems like i was celebrating to soon when i posted that booting into 64-Bit mode fixed the battery issue, as the "Service Battery" message and unstable battery health are back again. So, booting in 64-Bit is no solution to the problem, at least not for me.

To all,


Please post your battery info , in order to see if this is problem occurs just in some types of battery.

Until now, more affected seems to be MBP's 4.1 with Sony Battery.

I've given up on SL for now, at least until Apple address this issue. Restored pre-SL and battery is now functioning normally and as expected.

here is mine, with SL, booting into 64-bit mode

Same issue here. Funny thing is I didn't really notice until I installed 10.6.1. Battery took almost 24 hours to fully charge. I did the SMC reset to no avail. MBP is turning off completely after 30 mins or so of use. I did not have this issue under Leopard.

Apple please take a look at this issue.

For Battery Condition, mine will switch back to "Check Battery" when the "Service Battery" message appears in the battery icon drop down rom the menu bar. The message seems to appear while it's charging. After it's first been completely charged and then unplugged, it will disappear, and then reappear with about 2 hours remaining. Then it goes away again until it's nearly run out. Also, my time remaining is fun to watch as well. I JUST watched it go from 50 minutes to 1:10 minutes, and I've got nothing open but Safari and system Profiler.

Anyway, my battery info.

Same issue here, happening on both my White MacBook and my MacBook Pro 4,1 (79 cycles). Running Leopard off of an external drive doesn't have this problem. 10.6.1 didn't fix this like I had hoped it would.
