Tucked away in a latest Pixel Feature 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 telephone 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 elements?
Whereas we are able to’t know for sure with out Google’s say-so, I’ve carried out just a few assessments to assist determine it out. All of them counsel Pixels do certainly now help 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 telephone usually to see what occurred, and the telephone displayed a “Carried out charging” message as soon as the handset hit 80% and the plug stopped supplying energy. Up to now, 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 telephone hits 80%. Nonetheless, they proceed to show {that a} charger is related, so the telephone is aware of there’s an influence supply accessible. See the screenshot beneath for example.

That’s a fairly good signal that bypass energy is in play. Additional affirmation will be had by instantly monitoring the ability from the wall whereas the telephone is plugged in to see if utilization varies the provided energy. Listed below 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’d count on the telephone to eat in every of those cases, which is, once more, very telling. However what’s notably placing is how erratically the ability spikes up and down whereas on this state — biking a number of instances per second. You actually 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 right now, you’d count on a a lot slower charge of change.
If extra proof is required, toggle the telephone again into adaptive charging mode, and the ability from the plug immediately jumps up. Battery monitoring apps additionally affirm that the telephone is charging once more.

Like different manufacturers, Google’s non-obligatory 80% charging limit is designed to prolong battery health by decreasing voltage stress and trickle charging, which might speed up cell degradation. Nonetheless, the bypassing charging side we seem to see on the 80% restrict has another perks as properly.
For one, it means you need to use the telephone 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. Avid gamers, for instance, can play for lengthy durations with out worrying about their handset turning into too uncomfortable to carry or inflicting the telephone to throttle again on efficiency.
There aren’t actually any downsides right here aside from not having a full battery if you take the telephone off the plug. A devoted bypass charging toggle could be extra helpful for players, for example. 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 Telephone sequence, and Samsung and Sony provide it, too.
Sadly, I haven’t been in a position to check precisely which Pixel telephones this function is on the market on. It doubtless 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 verify precisely how this all works and can replace the article once we hear again.
