The recent battery update was a necessary thing, but it was producing a lot of very strange results. Standard flashlights were burning through light batteries (which are AAs or 9 volts) in just an hour or two.
Flashlights now burn a much more realistic 750mW instead of the 1560 (?!?!) that they were burning before. This means that a standard flashlight will stay lit for about 4 or 5 hours, which is much closer to what you'd expect IRL.
Heavy-duty flashlights are relatively unchanged. This item is a big mag-lite type thing that uses a medium battery (a lithium battery like in a phone or vape pen) rather than a AA. It's brighter but less efficient, and so will only stay lit for around 3 hours. At least it's waterproof and you can bonk zombies with it.
Stun guns now drain 2 power instead of 40, so you get about 28 uses before their batteries need charging.
Locked smartphones had the wrong charge value, at 120 instead of 56. This has been fixed.
AR glasses and advanced AR glasses now use internal batteries which need to be recharged. They have a much bigger capacity than before.
Updated the description for the bionic patient profession to reflect it using a cable charger now.
