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.

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.
If you need a phone that can last a long time without a charge, the G7 isn’t the device for you. LG is highlighting the phone’s 1,000-nit brightness, but if you max out the display to make it more viewable in direct sunlight, you’ll kill the battery even more quickly.
The good news: LG supports fast-charging with a charger they provide right in the box, and the company makes good on the fast part. After 30 minutes of charging, the G7’s battery was back up to 50 percent. A little under an hour will power the device up to 100 percent.
Still, based on our testing, your going to need to keep that charger handy if you plan on buying the G7 ThinQ when it arrives in store on June 1.
