LG’s G7 ThinQ packs a 3,000 mAh battery in its 6-inch frame, which means it should last as long on a charge as rival flagships with similar battery capacity.
But LG’s smartphones suffer from a critical issue: poor battery life. That’s despite its solid battery capacity and power-efficient Snapdragon 845 processor, which is identical to the mobile processor powering Samsung’s Galaxy S9. That device lasts two and a half hours longer than the G7 on the Tom’s Guide Battery Test, continuous web-surfing over 4G LTE. In this case, we used T-Mobile’s network.
We test each phone’s display at around 50 percent brightness — the G7 was set to 53 percent, to be exact — because using a phone at peak brightness will drain the battery more quickly.
LG G7 ThinQ Battery Life Compared
|Phone||Battery Size||Battery Life (Hrs:Mins)|
|LG G7 ThinQ||3,000 mAh||8:35|
|Huawei Mate 10 Pro||4,000 mAh||14:33|
|Google Pixel 2 XL||3,500 mAh||12:09|
|Apple iPhone 8 Plus||2,675 mAh (based on teardowns)||11:16|
|Google Pixel 2||2,700 mAh||11:07|
|Samsung Galaxy S9+||3,500 mAh||10:59|
|Samsung Galaxy S9||3,000 mAh||10:52|
|Apple iPhone X||2,716 mAh (based on teardowns)||10:49|
|Apple iPhone 8||1,821 mAh (based on teardowns)||9:54|
|LG V30||3,300 mAh||6:30|
Like its predecessor, last year’s G6, G7’s battery life underwhelms compared to the competition. The G6 turned in 8 hours and 39 minutes, and the G7 didn’t even match that, lasting just 8:35. LG’s V30, released earlier this year, turned in a paltry performance of 6:30 in our testing.
Every other high-end smartphone lasts hours longer than LG’s devices. The category average is 9:50, and flagships from Apple, Samsung and Google all sail past that mark. Huawei’s Mate 10 Pro is still the leader among flagship phones, lasting a whopping 14 hours and 33 minutes, but Google’s Pixel 2 XL (12:09) and Apple’s iPhone 8 Plus (11:16) aren’t too shabby, either.
