Compact size. Lack of excessive processing with the camera. Snapdragon for a reasonable price. Came from pixel 7a. Xperia 5ii (insufficient battery) then 5iii (excessive heat and poor battery), one of these will make a good backup but they're too old so battery doesn't last, now got Xperia 5iv. Very good all rounder. Lovely screen and superb battery. Not dropped under 50 percent yet after a whole day of use.
XM4 batteries are interchangeable to XM3. my XM3 is now packed with more power lol.
size of the battery is okay, it fits alright, it does not heat up, etc. it definitely works, thanks OP!
\* will return here for updates if there are some issues that i will encounter while using it, but so far, it works like a charm.
They should work, unless the batteries you received are defective. I bought mine from the same seller. I've been using it in my xm4 for a month now.
They put in bigger batteries into the new III series cameras, and after using one for a bit, the improvement is drastic. with my a6300, I would go through ~2-3 batteries on a day trip, but with the a9 and it's new battery, you can comfortably get through a day without worrying about the battery.
After a long time with Samsung, switched to Xperia 1 V coz of the headphone jack. Overheating & random battery drain has me regretting .
