iPhone 6 and iPhone 6s Tom's Guide found that the phone only lasted 7 hours and 25 minutes with continuous use, but at Trusted Reviews, tester Evan Kypreos had better results: his iPhone 6 lasted 14 hours when in heavy usage (at 50% brightness), and up to 35 hours when not being used at all.
Out of this year's iPhones, the 8 Plus has the best battery life. The iPhone X, however, had the worst.iPhone battery life (video playback test)

|iPhone X||11.45 hours|
Using the iPad to play a lot of music with the display turned off will give you great battery life. Streaming video over WiFi I get 5 minutes for every 1% drop in battery,for what it's worth.
Average smartphone owners may get even better battery life. We've used the Note 8 for nearly 24 hours, including over 4 hours of “screen on” time. You'll also notice the phone displays I have over 4 hours of battery remaining.

Every iPad is rated for roughly 10 hours of battery life while browsing the web, checking email, and chatting. But if you've just set up a new one, especially if you restored it from a previous device backup or you've just installed iPadOS 15, you might see more drain on your battery than you'd otherwise expect.
The Apple spec says battery life is up to 10 hours. There are too many variables of use to state an exact life. There's really no reason to run on full brightness, since it reduces battery life. The quickest way (and really the only way) to charge your iPad is with the included 10W USB Power Adapter.
Constant internet use of your iPhone 8 gives you about 12 hours of battery life. Audio playback gives you 40 hours and the phone has fast-charging capabilities of up to 50% in 30 minutes.
We all know there's no exact science when elements like heat and moisture are involved. In some cases, you may only have up to 18 months before you should consider replacing your iPhone 8's battery.
Take a look at our results: the iPhone 8 lasted an average of 13 hours, 31 minutes, while the 8 Plus lasted an average of 13 hours, 44 minutes.
Last year, when we tested continuous video playback on Airplane mode, the iPhone XR averaged 19 hours and 53 minutes. In comparison, the iPhone 8 Plus lasted 13 hours and 45 minutes. This discrepancy is likely due to a bump in battery capacity for the XR.
Apple claims that the battery life for most iPads averages 10 hours of usage, and can sometimes even surpass it. But for someone like me, those 10 hours are precious electronic charges to be savored.
The iPad 2020 generation is rated for 10 hours of web surfing over Wi-Fi or watching video, and that dips to 9 hours if you opt for the cellular model and you're using LTE.
