I posted recently about my struggles with my new 7a battery. I installed android 14 beta today and going to bed after 4 hours SOT I've got 50% battery left, the difference is ridiculous.
From my reading I'm led to believe Google will find a way to lose the gains by the time the release is final but I have my fingers crossed, it's turned the phone from a regret to a sound purchase so far.
That's pretty exciting. I have a pixel 6 pro and the battery life has been abysmal for a while. Like 50% battery after unplugged for 5-6 hours with minimal use. I've been trying to hunt battery draining apps but to no avail yet.
I'd already done every trick to try and maximise battery so perhaps my results are a little generous. Are you able to try the beta on 6 Pro? I recommend giving it a go.
I've been running the A14beta on my 7 Pro after reading a post by someone who said he was getting insanely great battery life after installing it. I can't quantify if it's better or by how much, but I don't regret the upgrade at this point.
