Tucked away in a latest Pixel Characteristic Drop, Google has lastly included the long-anticipated choice to cap battery capability at 80% as a part of the Charging optimization menu. However what does the cellphone do when it hits 80% and it’s nonetheless plugged in? Does it decelerate and trickle cost the battery, or does it bypass the cell utterly and supply energy on to the parts?
Whereas we are able to’t know for sure with out Google’s say-so, I’ve performed a couple of checks to assist determine it out. All of them recommend Pixels do certainly now assist bypass charging as a facet impact of the 80% restrict possibility.
Bypass energy for Pixels
To check, I navigated into the Charging optimization menu and switched my Pixel 8 Professional from Adaptive Charging to “Restrict to 80%.” I then proceeded to cost the cellphone usually to see what occurred, and the cellphone displayed a “Carried out charging” message as soon as the handset hit 80% and the plug stopped supplying energy. To date, that’s exactly what you’d anticipate.
Battery apps that monitor the state of the incoming energy additionally change from “charging” to “not charging” as quickly because the cellphone hits 80%. Nevertheless, they proceed to show {that a} charger is related, so the cellphone is aware of there’s an influence supply obtainable. See the screenshot under for example.

That’s a fairly good signal that bypass energy is in play. Additional affirmation could be had by straight monitoring the facility from the wall whereas the cellphone is plugged in to see if utilization varies the provided energy. Listed here are some averaged outcomes from my Pixel 8 Professional.
- Display off idle: 0.1W
- Homescreen idle: 0.74W
- App transition: 2.6W
- Geekbench 6 benchmark: 4.6W
- 3DMark benchmark: 7.6W

That’s just about what you’ll anticipate the cellphone to devour in every of those cases, which is, once more, very telling. However what’s significantly putting is how erratically the facility spikes up and down whereas on this state — biking a number of instances per second. You definitely wouldn’t cost a battery like this; as a substitute, this seems to intently comply with the facility consumed by the duty at hand. If Google have been powering the battery right now, you’ll anticipate a a lot slower price of change.
If extra proof is required, toggle the cellphone again into adaptive charging mode, and the facility from the plug immediately jumps up. Battery monitoring apps additionally verify that the cellphone is charging once more.

Like different manufacturers, Google’s non-obligatory 80% charging restrict is designed to lengthen battery well being by lowering voltage stress and trickle charging, which may speed up cell degradation. Nevertheless, the bypassing charging facet we seem to see on the 80% restrict has another perks as properly.
For one, it means you should utilize the cellphone whereas it’s plugged in with out biking the battery — one other boon for battery well being. It additionally makes for a cooler handset if you happen to’re utilizing it whereas charging. Avid gamers, for instance, can play for lengthy durations with out worrying about their handset changing into too uncomfortable to carry or inflicting the cellphone to throttle again on efficiency.
There aren’t actually any downsides right here apart from not having a full battery if you take the cellphone off the plug. A devoted bypass charging toggle could be extra helpful for avid gamers, as an illustration. In fact, Google isn’t the primary Android producer to incorporate a battery charging bypass function. It’s a staple of Android gaming handsets just like the ASUS ROG Cellphone collection, and Samsung and Sony provide it, too.
Sadly, I haven’t been capable of check precisely which Pixel telephones this function is obtainable on. It probably requires a USB energy chip that’s able to bypassing the battery, which can or might not be the identical throughout all latest fashions. We’ve reached out to Google to substantiate precisely how this all works and can replace the article once we hear again.
