User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.86 Safari/537.36

Steps to reproduce:

I just migrated from Apple Mail to Thunderbird v45 in OSX v10.11.4.
I can work with my macbook whole day long with Apple Mail, but I need to find my charger at about lunch time after Thunderbird migration                                                                                                                                                                                                                                                                                                                                                                                                                 

I also can feel the temperature on my keyboard after Thunderbird started for 15 mins



Expected results:

My battery usage can back to normal

When exactly did you install?
When did all the imap mail finished syncing?
Is the progress bar constantly "running" as described in bug 562977?

Comment 2

[ivanluiok]

I installed TB45 4 days ago, and my email is POP3, not IMAP.
I referred bug 562977, and I tried to make the changes below, let me observe the battery usage for few days first.

layers.acceleration.disabled -> true
layers.offmainthreadcomposition.enabled -> false

I just had a 4 hours meeting in customer's office, and both temperature and battery usage went back to normal, 20% battery was used.

I considered the case is closed.

Thanks Wayne.

You may have a workaround, but there is still a problem :)
So duping

ivanluiok,

Followup questions...
1. The settings in comment 2 are the default, which suggests you may have overridden the default by enabling HWA. Do you recall changing the value at Preferences > Advanced > General > Use Hardware Acceleration?  And what is the value there now?
2. What model macbook and video?
