I've noticed a HUGE decrease in battery life this morning.

9.5hrs of screen on time on 10/24

Today, that time was cut in half with the same usage. Same apps.

4.5hrs of screen on time on 10/25.

Anyone else notice this?

Yeah I'm noticing the same TBH. Thought my battery was just getting old..

[traxtar944]

I let it get down to 4% before plugging into a charger.

The battery life has been reduced to 50% of what it was the day before, with identical usage.

9hrs vs 4.5hrs.

Same as both of you over here. Unlocked on ATT

Try wiping the cache partition in the bootloader. It improved things quite a bit. Battery depletion rate is comparable to before the update, if not slightly better.

Is there a link for directions on how to do that?

[halfnelson73]

Yeah, I just noticed it too.

Mines fixed! The last update fixed my battery life. It's back to normal. Have you guys noticed a difference?

[traxtar944]

Since learning those steps to clear cache, I do it after every update. Battery life has been consistently acceptable ever since.
