> In the last 12-18 months, a bunch of Android phones have gotten large battery capacity upgrades
Can you give some examples? I'd like to test one out but I'm not buying the most recent product as a rule.
The OnePlus 13 and Oppo Find X8 both got 10% capacity upgrades over their previous iterations but with the same size/weight. The Honor Magic V2 also has a huge battery despite being a very slim foldable (5,000 mAh, compared to 3,000-3,500 on the ones from Samsung and Google).
Oneplus 13 with lithium-silicon battery tech. This is the new tech which allows for higher capacity at the same size as before.
