[Sony Xperia X Performance Guides, News, & Discussi] RockStar2005:
hey lucifero,

I think the battery life is just fine. The phone comes with a power saver feature called "Stamina Mode" (SM) too that helps to save battery life, which is good for if you're gonna be out and about and can't charge it for several hours. Last week I went out with my phone around 11am and didn't get back 'til home 'til 10 and with SM I actually made it 'til I got home and that was with pretty heavy usage throughout the day....... checking internet/e-mail, taking a bunch of photos, at least a few phone calls, using Uber/Lyft apps, etc etc. I will say that unless you're using it heavily THROUGHOUT the day it can most definitely last more than a day easily, esp if you got SM enabled. Perhaps even without.

The phone will work with any GSM-based carrier. These include T-Mobile, AT&T, and several others. Check here to make sure before buying that it'll work with your carrier. (Model #: F8132, or F8131 for single-SIM). Since it's sold unlocked and not through carriers, you won't get VoLTE (including HD Voice), but in all honesty, you don't really need it. I had a locked T-Mobile S7 with VoLTE etc cuz was from carrier, and the sound quality on the XP for calls and just the speakers in general sound MUCH better than the S7 WITH those features. I live in an area (Chicago suburbs) that has a very strong LTE reception, and so I'm in LTE all the time. During calls it'll go down to 3G/4G (which shows up as 3G/H+ cuz it's int'l......LTE shows up as LTE, not 4G LTE), but then back to LTE when call is done.

When my area gets Band 12 in 3-6 mos (T-Mobile, my carrier, just purchased a ton of and are setting it up now for deployment), I am expecting my reception to be even better. It SHOULD allow my calls to stay in 4G but I'm not 100% sure about that yet. I was told it would but I'll see. But again my calls now sound great anyway b/c the phone's sound equipment is so well put-together.

That may be so about the metal, but the FRAME of the phone is polycarbonate, or plastic, and that will help to ensure you get the best signal quality. So I wouldn't worry about that.

I LOVE this phone and wouldn't trade it for any other phone out there. And as you know I already had the S7 and the HTC 10.

If you buy it, I highly recommend this CLEAR case. Ringke and Spigen are the best 2 IMO. The one I bought is very close in quality and I only bought mine b/c a month ago the Ringke one wasn't out and I had no clue they were making one. (Note: Spigen didn't make one for the XP b/c they're p*ssies lol). I'm pretty happy with mine so I'll prob just stick with it, but if I could go back I would've maybe just waited for the Ringke if I knew it was coming out so soon. lol

Chargers: To get the most bang for your buck with this phone, I'd recommend getting the Quick Charge 3.0 chargers I bought off Amazon. The phone appears to be 3.0 compatible since Sony actually made a QC 3.0 charger specifically for it. The S7 isn't (at least fully) 3.0-compatible from what I've read. But the Sony one is pricey so I just got these highly-rated chargers for good prices instead.......... 1) QC 3.0 wall charger 2) QC 3.0 Dual car-charger (or Single).

Hope that helps. Which carrier you got btw?
