Sony Xperia 1 V battery replacement
A phone that no longer reaches the evening, shuts down at 20% in the cold, or gets warm doing nothing much: those are the three ways a worn cell announces itself. Lithium cells lose capacity by cycle count, not by how carefully you treat them, and after two or three years the drop is steep rather than gradual.
Charging is 30 W wired, so a cell that has aged badly often shows up first as a phone that charges quickly to 80% and then crawls.
We fit a new 5,000 mAh cell: the rear glass comes off under controlled heat, the old adhesive is cleaned out, the new cell goes in on fresh adhesive, and the phone is resealed and run through a charge cycle before it goes back to you. Typically one to two hours once the part is on the bench. We order per repair rather than hold stock, so booking ahead is what makes a same-day fit possible.
If the battery has started to swell, stop charging it. A swollen cell pushes the 6.5″ 4K 21:9 OLED or the rear glass out of the frame, and what starts as a battery job turns into a screen job. Tell us when you book and we will handle it accordingly.
Your data is not touched. Bring it to us in London, or post it in - UK‑wide, tracked both ways. One thing we will not pretend: the phone left the factory rated IP65/IP68, and while we reseal it properly, no workshop can certify that rating again after the phone has been opened.
