Google has just made one of the biggest Pixel announcements ever, and it includes not two but three Pixel 9 models. There has been an increase in the battery sizes and some improvements to the charging speeds with the Pixel 9 series.
As you might suspect, the Pixel 9 Pro XL, which is the largest of the three, comes with the most battery capacity. On the other hand, the Pixel 9 shares the same battery size as the new Pixel 9 Pro.
As for charging, the Pixel 9 Pro XL is the quickest of all three variants, while the Pixel 9 and 9 Pro share the same charging speed between each other.

Pixel 9 battery upgrades
The Pixel 9 Pro XL has almost the same dimensions as last year's Pixel 8 Pro, but its battery has mostly the same capacity at 5060 mAh (5050 mAh on the predecessor).
The Pixel 9 and 9 Pro have considerably smaller batteries at 4700 mAh, which is more than last year’s 4575 mAh on the Pixel 8. Here's a breakdown of all Pixel 9 series battery sizes:
| Battery capacity/phone | Battery size |
|---|---|
| Pixel 9 Pro XL | 5060 mAh (vs 5,050 mAh on Pixel 8 Pro) |
| Pixel 9 Pro | 4700 mAh |
| Pixel 9 | 4700 mAh (vs 4,575 mAh on previous model) |
Google claims that all three Pixel 9 models can last more than 24 hours on a single charge, and up to 100 hours if you turn on the Extreme Battery Saver mode.
Google also states that the Tensor G4 has better power efficiency than the Tensor G3, so we expect that to play a big part during our dedicated battery life tests.

Pixel 9 charging upgrades
Faster charging
While the power input is the same as with the Pixel 8 series, Google has managed to make the Pixel 9 lineup charge faster. The Pixel 9 Pro XL can go from 1-70% in just 30 minutes of charging, while the Pixel 9 and 9 Pro from 1-55% for the same amount of time.
It’s worth mentioning that Google has done these measurements with its new 45W power adapter, whereas last year the company used its 30W adapter.
Pixel 9 Pro XL charging specs:
- 37W wired
- 23W wireless
- 5W reverse-wireless
Pixel 9 Pro XL charging specs:
- 27W wired
- 21W wireless
- 5W reverse-wireless
Pixel 9 charging specs:
- 27W wired
- 15W wireless
- 5W reverse-wireless
Does the Pixel 9 have reverse wireless charging?
Yes. Just like its predecessor had reverse wireless charging, all Pixel 9 models come with 5W of reverse wireless charging on board. Google calls this feature Power Share.
What charger does the Pixel 9 use?
The Pixel 9 series works with the old 30W charger, but Google has done the charging tests with its new 45W fast charger.
How fast does the Pixel 9 charge?
Given the slightly faster charging times that Google has stated for the Pixel 9 series, we suspect it will take about 10-15 minutes less to charge them from 1-100% compared to last year’s models, which had an overall time of around 1 hours and 30 minutes.
