I was so disappointed with my pixel 10. It’s kept a pixel 7 alive for years (great phone) and only swapped when the battery swelled. The 10 was no better and potentially worse, I replaced the battery on the 7 myself and lamented it’s loss to my son (he gets my cast offs). Such a good line of phones that’s clearly peaked.
There’s a guy on YouTube that covers this. Powders can contain bleach and cleaning agents in the same mix since they are dry. This gives the best of both worlds. With liquids, the two interact and break down the coach resulting in a poorer result. Pods can keep the components separate but why pay the extra? Something like that anyway. Personal experience is that liquids leave a funky buildup over time that you just don’t get with powders.
