Hello everyone,

Have done some searches here and elsewhere and don't quite know what to make of my battery drain problem. I thought that I was practicing good battery behavior (wifi off, turn off when not using, low light. I read 30 to 60 minutes a day. Prior to the 5.7.3 update I would sometimes forget to turn wifi off and saw no serious battery drain. Prior to the 5.7.3 update I'd get 10 to 14 days or so on a charge. I'd say that I'd recharge when I was at about 20 percent or so.

As far as I know everything is indexed. I have typed in some random nonsense characters to be sure.

My Kindle PW (6th generation) just updated to 5.7.3 three or four days ago. Interestingly, since then I seem to have some issues with the battery draining after only a couple of days. The first time was a day after the update and may have been my fault as I left it in wifi in sleep mode when the battery was at about 33 percent charged. It was prompting me to recharge the battery which I did two nights ago (over night).

I normally leave the kindle off when I am not using it or try to. Kindle was in airplane mode, no wifi. Had only read maybe three or four hours, an hour or so of that at a wifi hotspot where I had wifi on but turned off when I left. Tonight I went to use my kindle and it was again prompting me to recharge. Which I am doing as I write this. Prior to recharging, I restarted the kindle.

I thought that perhaps whispersync might be eating up the battery so I just turned whispersync off. I honestly don't recall if whispersync was on or off before the 5.7.3. update.

Any suggestions appreciated. I'll post back any updates.
