Hello,
my MacBook Pro late 2007 has just been updated from 10.11.4 to 10.11.5 and I can't believe my eyes how much battery working time efficiency has been dropped. From approx. 3-3,5h in 10.11.4 to 1-1,5h in 10.11.5 now! Just the same computer usage with no new software as it was on 10.11.4. Battery is 2 years old with approx. 230 cycles and still 70% alive according to Battery Health. I have calibrated it and done SMC reset. What else should I do?
Best,
Martin
After updated to 10.11.5 Battery Service warning came out… 10.11.4 has never complained
Hi, as I have reported there were the same apps in 10.11.4 and in 10.11.5 now – just Safari & iTunes on daily basis. Battery service warning has appeared what has never happened in 10.11.4
Every thing you've written here points in the same direction: there's something wrong with that battery. Is it from Apple?
Yes it is original one. Worked fine in 10.11.4 with no warnings
Yes I know my MacBook Pro battery is 300 cycles lifespan limited but still it didn't justify double reduce battery working time in 10.11.5
Is it possible downgrade to 10.11.4?
Thank you for all suggestions. Upgrade to 10.11.6 and reset the System Management Controller (SMC) has helped. No more battery service warning and battery working time has get back as it was before 10.11.5
