I been charging my battery in sleep mode for months, for some reason is never full when i use it, according to the molecule thing or any hombrew emulator i use, is always 88% And i mean a actual vita not like vita tv. I wonder if i should use the power adaptor instead of console usb.The Vita like the PSP has a very good power saving sleep mode. May I ask why you turn it off? I leave it on power saving sleep mode all day and don't see much of a battery lost from full battery. However, just about every manufacturer edits the battery % so it stays at 100% longer than it's supposed to even tho it is in fact losing battery. Like 30 mins of gaming and battery goes 100-95, then next 30 min, 95-70 haha.
Yes, use the power adaptor. Console usb has a low output of power, especially if the console is in sleep mode. I know xbox one can charge things via usb while it is asleep, but it is extremely slow. Maybe it just doesnt have the juice to power your vita battery up the rest of the way. Hopefully your battery hasnt developed a memory somehow. You could also try turning the vita on, let it drain completely, then charge it using the power adaptor. I hope you resolve the problem. Good luck.I been charging my battery in sleep mode for months, for some reason is never full when i use it, according to the molecule thing or any hombrew emulator i use, is always 88% And i mean a actual vita not like vita tv.
