    Dear All,

     

    I turned off SIRI and get better battery life....I am not too sure if that is the reason....but battery seems to improve.

     

    Last night, I was playing around with my phone and I knowingly turned of SIRI ( to troubleshoot my lousy battery life)...

     

    The battery today was seemingly much better.  It is now 5:30pm I and my battery level is at 55%...for the past 2 days, my battery was at >30% or high 20....

     

    I will try for more days and see.

     

    Any one experience this issue or is it me.

    Good morning everyone! Just to keep you updated how the update via iTunes and the restore from backup improved the battery life.

    Seems to be something wrong with the over the air update. When I first did it OTA the battery drained 30% over night. With the iTunes Update it only lost 5-6%. Usage & standby is satisfying aswell.

    Ok well its not the email client. This is when using exchange email or gmail exchange option. What happens is the app may get hung up checking email  or in communication with the server for whatever reason and never stops so running constantly draining battery and heating up the device. Sometimes stoping the app and restarting (hard restart) will solve it. Removing the email account ,rebooting then adding it back is the more tyical fix. Its more like an exchange bug than an iOS bug. And not the email client /app itself

    How can an email account become corrupt? That definitely sounds like an OS issue, not email client. Apps causing the cpu to run excessively? That's a combo issue imo. If, and I mean, if, the app is to blame at all then it means the app itself wasn't tested enough to add safeguards to it from doing so and the OS lacks the same features.

    Simon one other thing you can do if you want SIRI available for use but still reap the battery life benefit is turn off the "raise to speak" setting. That turns off the sensor that fires off SIRI when you put the device to your ear. Its always running (you can see it with a digital camera). Old reports from when SIRI came out state this helps and others state that sensor does not use a lot of battery. However its odd that folks can turn of SIRI totally and report better battery. SIRI is not being used except when activated other than the raise to speak option. If you do this you have to turn off the phone after changing the setting for it to actually turn it off.

    I updated via iTunes yesterday.  Battery has been horrible on iPhone 5.  down to 72% with 1 hour "usage".  When I went to bed i had 85% or so, woke up with 75%.  10% loss on "standby" over 7 hours.

    I was at 100% charge this morning before leaving for work.  After just under two hours I am down to 60%.  Something else I noticed, I have lost LTE service in locations I previuosly had it.  Like at work!  Now tell me that isn't a problem!  I have no background running apps.  I haven't even used my phone this morning other than turning it on.  I'm curious about the Microsoft Exchange corrupt account possibility.  I will delete my account and return my phone to full charge and see what happens.

    Usage: 8h21min

    Some more details:

    - connected to home wifi (no mobile date because sick in bed)

    - brightness 50%, auto adjust

    - looking for email every 15min

    - bluetooth off

    - siri on

    - icloud sync (mail, contacts, calendars & reminders, documents & data)

    LTE seems to be draining the battery aswell. A friend of mine noticed it after upgrading to 6.1.

    But I can't confirm, since o2 Germany doesn't support LTE yet.

    The matching stby and usage figures it indicative of the exchange issue. Its pretty common and the removing-re-adding of the account typically solves it. Keep us posted.

    Well, after restoring to a full charge and only deleting my Exchange account, after almost an hour I am still at 100% which before I was under 80% after an hour.  I have now readded my Exchange account and will see if there is any noticiable differences in battery life.

    After adding back my exchange account my battery life is exceptional.  So it looks like it was a corrupted by the installation of 6.1???  Either way, deleting and adding back corrected my issue.

    Dear All,

     

    How do one really tell if the battery has improved?...my specs

     

    Yesterday :- 62% Usage=2hrs40mins, Standby=6hrs12mins.

     

    Today (after removing Apps) :- 73% Usage=2hrs21mins, Standby=9hrs, 18mins.

     

    Are those improvements?  Or same?  really can't tell.

     

    What is more "important" stats?  Standby or Usage.  I personnally think that Usage is more important...as Apps are being run and programs used.

     

    How can we really compare...should we always compare them at the end of the day or at a certain battery %.  or at certain time.

     

    Reason I am asking is that I felt that my battery today is really alot more efficient.

     

    Of course, I Removed...News Apps (an instead Bookmarked them in Safari)...

     

    Removed a on-line movie player that I installed. 

     

    Today, I felt my battery improved some what...not much but slight.  But I hesitate to call that a "true improvement" as tomorrow the battery might lose its efficiencies again.

     

    Thank you
