Tucked away in a current Pixel Function 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 just a few checks to assist determine it out. All of them counsel Pixels do certainly now assist bypass charging as a facet impact of the 80% restrict choice.
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 “Finished charging” message as soon as the handset hit 80% and the plug stopped supplying energy. To this point, that’s exactly what you’d count on.
Battery apps that monitor the state of the incoming energy additionally change from “charging” to “not charging” as quickly because the cellphone hits 80%. Nonetheless, 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 may be had by instantly monitoring the ability from the wall whereas the cellphone is plugged in to see if utilization varies the equipped energy. Listed here are some averaged outcomes from my Pixel 8 Professional.
- Display screen 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’d count on the cellphone to devour in every of those situations, which is, once more, very telling. However what’s significantly placing is how erratically the ability 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 ability consumed by the duty at hand. If Google had been powering the battery at the moment, you’d count on a a lot slower fee of change.
If extra proof is required, toggle the cellphone again into adaptive charging mode, and the ability from the plug immediately jumps up. Battery monitoring apps additionally affirm that the cellphone is charging once more.

Like different manufacturers, Google’s non-obligatory 80% charging restrict is designed to delay battery well being by decreasing voltage stress and trickle charging, which might speed up cell degradation. Nonetheless, the bypassing charging facet we seem to see on the 80% restrict has another perks as effectively.
For one, it means you should use 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 in the event you’re utilizing it whereas charging. Players, for instance, can play for lengthy intervals with out worrying about their handset turning into too uncomfortable to carry or inflicting the cellphone to throttle again on efficiency.
There aren’t actually any downsides right here aside from not having a full battery while you take the cellphone off the plug. A devoted bypass charging toggle can be extra helpful for avid gamers, for example. After all, 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 supply it, too.
Sadly, I haven’t been in a position to check precisely which Pixel telephones this function is accessible on. It possible requires a USB energy chip that’s able to bypassing the battery, which can or is probably not the identical throughout all current fashions. We’ve reached out to Google to substantiate precisely how this all works and can replace the article once we hear again.
