Galaxy Nexus battery drain horrible after update

[eroh]

I own a Galaxy Nexus worked really great - great battery life especially when i installed my 5000 extended battery from mpj, easily last a day and night even played a lots of data...until the update. I was getting so frustrated with it, about 30% more of the battery had drained while it was supposedly asleep. It ended up being on the charger more than it was in my hands.After dealing with the battery life, i did factory reset and reverted back to the original system. It is as if I have my fresh out of the box.

Want to know why update causing battery drain?

What version did you update to and from?

I suspect it was likely due to a rogue app, as doing a factory reset from within the settings is just a wipe of the phone, retaining the current OS version (haven't done this in a while but IIRC, that was how it worked). If you reflashed however, it could be a battery recalibration error, since you are using an aftermarket battery. Give it a few good charge/discharge cycles (from about 10% to full) to see if it recalibrates.

What update was it? There's a lot of complaints about the 4.3 update for the S3 -> http://www.theregister.co.uk/2013/11...pgrade_pulled/

Thanks for your response. It was 4.3 update and I've tried battery calibration without improvement, but all seem well after I went back to the previous system version. Have no idea about the battery issue.

yup..it was 4.3 update. Same way that I use my phone, but a dreadful decrease in battery life
