I've had all pixels xl, and most of the nexus phones.
With the pixel line, I had never been so happy with battery, specially pixel 2 xl. Battery would last 1.5 to 2 days for me (I am very conservative in usage)
However, with the 3 xl, at the end of the day yesterday, I had 39%> This was a day I did not use the phone except for 10 sms, quick stock checks, 2 emails, no phone calls, 15 minutes of music with bt headphones in the metro.
Last night, I put it in safe mode, charged it. TODAY, I took away from the charger at 6am, checked emails, back in the pocket. At 8 am, I had 90%.
Removed from safe mode at 8 am. Checked some messages, spoke for 10 minutes over the phone, checked emails and stocks. It is now 9:20am and my battery is at 80%
Not good. I am really disappointed.
Could I have a defective unit? Am I spoiled with my excellent pixel 2 xl? I did see one youtuber complaining about his battery.
I am afraid mine is defective. If not, I want to go back to the pixel 2 xl.
If you have yours, and had a pixel 2 xl, please let me know how you feel about it please!
UPDATE 12/17/18: Nothing really changed much. Pixel 3 XL is horrible with the battery when compared to Pixel 2 XL. What a disappointment in this phone, all over the place. Battery, Buggy, Notch, Audio Recording, Video Recording, Face Unlock, Gestures, etc. What a waste of hard earned money. Of all Pixels and Nexus, this is together with the Nexus 6, the most I have been disappointed.
I truly love these phones, what they represent and all, but after years with the 'google phones', it might be time to try something else.... seriously.... with this phone, the fact that I still did not receive a $50 credit from google, and all these $300 discounts, with free pixel wireless charger and pixel earphones, after 2 months from launch, it makes me extremely disappointed of being an early adopter. Next year I am definitely waiting until January, after reading all reviews and trying it out first before I buy, or just getting a different brand phone.
I am very disappointed this time around.
