Buy Laptops With 50 Percent More Battery Life Than You Think
You probably already know that the battery life of laptops, tablets and phones is not always true. Laptop Magazine explains why and offers a sound rule of thumb for buying your next laptop.
Mag laptop battery tests (continuous web surfing over Wi-Fi at 100 nits brightness) show a discrepancy between the manufacturer’s maximum battery life and benchmark results.
One reason for the discrepancy is that PC makers use different benchmarks and benchmarks (sometimes not as demanding as those used by reviewers or consumers) to assess battery life.
It just sucks when your computer shuts down a few hours earlier than you expected, so take their advice:
As a consumer, you can vote for the best laptop market with your wallet. Buy laptops that are objectively tested with at least 50 percent more battery life than you think you will need in a day. If you think you can actually use your laptop away from your desk for 5 hours a day, buy something with 8 or 10 hours of battery life as measured by us, not marketers. You might end up with a slightly thicker laptop, but you’ll be much happier if you’re not chained to the wall.
