Apple's upcoming iPhone 7 Plus will have a 3,100 mAh battery and the option for 256GB storage, Chinese website MyDrivers claims.
The battery is said to be 12.7% larger than what's seen in the iPhone 6s Plus (which features a 2,750 mAh battery). Other rumors state the phone will be almost as thin as the newest iPod Touch, so this is questionable, although if the headphone jack is indeed removed, maybe this is all achievable. There is no word in the report about base storage. Lastly, the report adds credibility to the buzz about the iPhone 7 and 7 Plus sporting 4.7'' and 5.5'' screens, claiming the same.
Last we checked, the iPhone 7 and 7 Plus were said to have a TSMC-built A10 chip and Intel 7360 LTE modem; the 7 Plus may have 3GB RAM.
