The iQOO Neo 12 battery capacity is 9000 mAh, confirmed by iQOO when it launched the phone in China, together with 100 W wired charging. That is about a fifth more than the 7500 mAh in the Neo 11, and it comes from a single silicon carbon cell rather than two cells.
Some phone listings still show 7500 mAh, copied from the Neo 11 before launch. An India launch has not been confirmed at the time of writing, so figures for an India model may differ.
Quick facts
iQOO Neo 12 battery capacity at a glance
| Item | Figure |

| Capacity | 9000 mAh |
| Cell | One silicon carbon cell |
| Wired charging | 100 W |
| Previous model | Neo 11, 7500 mAh |
What silicon carbon changes
Silicon carbon anodes store more charge in the same space than the graphite used in older cells. That is how phone makers fit 7000 to 9000 mAh into bodies not much thicker than a 5000 mAh phone. The cells behave much like any lithium battery in daily use: heat and long periods at full charge still age them.
Bypass charging for games
iQOO's bypass feature lets the charger power the phone directly during games instead of charging the battery at the same time. That keeps the cell cooler and slows wear for people who play while plugged in. It is worth turning on if you game for long sessions; look for it in the game mode or battery settings.
iQOO Neo 12 battery capacity compared with earlier Neo models
The Neo line has grown quickly in capacity. The Neo 11 carried 7500 mAh, and earlier Neo phones sold in India were in the 5000 to 6000 mAh range. Jumping to 9000 mAh in one generation is mostly thanks to silicon carbon cells, which pack more charge into similar space. The phone is a little heavier than older Neo models, but not by as much as the capacity jump suggests.
If the Neo 12 arrives in India, compare its India spec sheet with the China figures. Makers sometimes trim capacity or charging speed for other markets, and the India figure is the one that matters for buyers here.
Battery life with a 185 Hz screen
The Neo 12 pairs its large battery with a top-tier chip and a 2K display running at up to 185 Hz. Those parts draw a lot of power, so 9000 mAh is what keeps the phone comfortable for a day and a half of heavy use. Lowering the refresh rate outside games adds hours. For context, see our highest mAh battery mobile roundup.
Charging time at 100 W
100 W fills a 9000 mAh cell in well under an hour with the iQOO adapter. As with every fast charging phone, the last tenth is slower. If you charge overnight, an ordinary USB C charger works too, more slowly and with less heat.
If you are waiting for an India launch
iQOO usually brings Neo models to India, sometimes with small changes to battery or charging. Until then, phones on sale here with big batteries are listed on our 7000 mAh and 8000 mAh pages, and other recent capacity questions such as the iQOO Z11x have their own pages.
Looking after a 9000 mAh cell
A big cell takes longer to wear out simply because it goes through fewer full cycles per year. You still get the most from it by avoiding heat: use bypass charging in long games, avoid charging under a pillow, and turn on any charge limit option the phone offers if you usually charge overnight. When the time comes for a replacement, an iQOO or vivo service centre is the right place, because silicon carbon packs and 100 W charging need the correct part.
