Battery problems, .668 update, and Hotmail
I've recently upgrade to a 64gb Playbook, and not long after applied the .668 update when it came out. I then started to suffer horrific battery life - within 12 hours on standby the battery would be done to 2% or so.
All the usual tricks - doing a hard reset etc. - had no effect.
In an effort to track it down (and with the realisation that a backup of settings in .668 wasn't going to restore to the previous release - bummer!) I started to disable things that could affect battery life.
First stop was email accounts, disabling them one at a time. The first one was Hotmail - and bingo! Battery life back to normal.
Clearly with Outlook.com MS have 'done something' to how their public email systems work - whether it's a change in push, or polling, or what, I don't know (and can't debug on a tablet).
Yes, I understand that push email and polling for email will have an impact on battery life - but it should never be this severe, and certainly never used to have this sort of impact.
My Playbook is configured to pickup email from 7 self-hosted email accounts, GMail, Hotmail, LinkedIn, and Facebook - it gets used very heavily and so I'm aware of what battery life should be like for my 'normal' usage.
Anyway, disabling all Hotmail/Live/Outlook accounts on your Playbook should help put battery life back to normal.
As a test, after two days of normal battery life, I fully charged the Playbook, and re-enable my Hotmail account. Back to 3% battery after 12 hours on standby.
Disabled the account, recharged the Playbook, and 36 hours later I've got 70% charge still.
So I'm fairly certain, after this testing, that it's not the .668 update that caused battery issues, it's MS's email systems.
YMMV and all that, but I'd be interested to hear from anyone else who:
- has poor battery life with the pulled update, but *doesn't* have a Hotmail/Live/Outlook email account enabled
- has disabled their Hotmail/Live/Outlook accounts on their Playbook - what's the effect on battery life afterwards?
