Battery drain appears fixed by 7.1.0.569 on AT&T

**ramorris** · 08-01-2012, 04:54 PM

I had an abrupt battery drain occur recently - normally my 9810 could easily go a full day on an overnight charge (even with Bluetooth and wi-fi on constantly) and about a month ago it started crapping out in about half that time. A new battery didn't help.

I installed 7.1.0.569 and it took a day or so of reboots but now it seems back to its old self! Knock on wood. Just thought that info might be helpful. Best, R

Can someone refresh my memory. Is the AT&T mic issue with all BBs, or just the 9900s? If it is with all, has it been resolved with .569?

The issue is with 9810's and 9900's and it is an ATT issue with all .4XX and .5XX versions only in some areas. I have had no problems in Louisville or Bowling Green(KY)or Indianapolis, IN areas.

As newcollector mentioned, it's all .4xx and .5xx builds, in a fairly sizable list of AT&T locales. And there's also an issue with requiring a tethering plan for hotspot to work. So, for me to switch from .378, I'd need to know both are fixed.

No mic problems on 569 in Central TX - Austin/San Antonio. R

Is your area one that had problems on AT&T with earlier builds? And does it give you a message that you need a tethering plan in order to use hotspot? And, since your info doesn't say which carrier, are you AT&T?

Never had any problems on AT&T in central TX - and no Hotspot requires activation. R

Yeah its been more than a week now and we're back to our old 9810 - I can leave on Bluetooth and Wifi constantly and the battery drain is completely returned back to the pattern from a few months back. For instance, I've been unplugged since 8:30 am - its now almost 3:30 and the battery level is at 70%!!! This includes constant bluetooth bridging to my Playbook, and constant wi-fi access and several texts.

So to re-cap - I had great battery life till abruptly about 2 months ago- purchased a new battery - no difference and finally after a trip I had planned could take the time to install the 7.1.0.569 OS on an AT&T phone. Immediately my battery performance returned back to the pre-drain state I had seen from purchase last August till late May.

I'm a very happy camper. Rick
