Battery Life

The G7 didn’t have all too impressive battery life and the culprit here was the phone’s rather small 3000mAh battery as well as the very high base power consumption of the phone. The new G8 addresses the former issue with the inclusion of a new 3500mAh battery, however there’s still remaining concerns regarding the phone’s base power consumption.

The G8 seemingly continues to use LG’s own DDIC in the form of an SW43410, and this unit showcases the same issues as previous generation LG Display phones: The phone still idles at a black screen with a base power consumption of 580mW, which is extremely high and pretty atrocious.

Samsung with the new S10 generation seemingly moved on to a new process panel and DDIC generation as the phones base power consumption saw a significant reduction down to ~390mW. What this means for the G8 is although the battery is larger than the G7, we’re not really expecting the phone post very competitive battery results.

In the Web Browsing test, the G8 indeed slightly loses out to the G7 of last year. Even though the new phone has a bigger battery and more efficient SoC, it doesn’t help the phone as the new OLED panel is more power hungry than the G7’s LCD. For similar reasons and suffering from even high base power consumption, the LG V40 ended up with even more atrocious battery life results, among the worst of 2018’s devices.

In PCMark the G8 fares better than the G7 and V40, however in absolute terms still lags behind the newer competition from Huawei and Samsung.

Overall, it’s massively disappointing to see LG struggle yet again in terms of battery life. I think we can now safely blame this on LG’s display panels and DDIC choices which have not improved over the last few generations, and rather have seen degradations in terms of power.

    More evidence to be used against LG when upgrading from my V30 when it breaks...
  • MananDedhia - Wednesday, May 1, 2019 - link

    I currently use a V20 and feel exactly the same.

    I have a V20 and the reason I never upgraded was no swappable batteries.

    for those whove never tried it, you should. you go from 5% to 100% in 1 minute. I carry no extra charging cable or charger, I slip an extra battery in my wallet and always have my screen brightness at 100%. never worried about battery draining.

    at home the phone is never connected to any cable. I simply charge the other battery in the cradle

    LG has massive issues with their phones imo. the g4 bootloop I went through. issues with the camera glass breaking on my v20 and aftermarket batteries dont work well as well.

    unfortunately im getting a 2nd v20 to have because of the swapping batteries. huge plus for me.

    For the life of me, I can't figure out why at least one phone manufacturer doesn't offer a decent phone with a removable battery. All the phone makers have decided that we want to throw away our phones after using them for 2 years, because the batteries no longer hold a decent charge.

    For the love of God, give us a phone that is designed to survive a drop or two. Making phones with glass backs, no bezels for protection and curved edges where the screen is higher than the bezel is insane. It really bothers me that this review had no evaluation of how well the LG G8 will survive a drop, but it spends so much time talking about its 0.6 mm increase in the thickness, as if anyone cares. The LG V20 was the last decent phone that LG made because it had a removable battery and was designed to survive normal drops.

    HTC, Motorola/Lenovo, LG and Sony are losing millions of dollars every quarter trying to sell phones, but none of them have figured out that maybe they should off something different, like a durable phone that is not based on planned obsolescence. The reviewers like Frumusanu would tell us how horrible it feels to hold a phone with a polycarbonate case, compared to a glass case, and how thick the bezels are, and how we simply can't live without IP68 rating, but those of us who care about the longevity and lasting value of our phones would buy it in droves.

    I have gotten so disgusted with the planned obsolescence in the phone industry and the monetization of my data and the collection of my data to train AIs, that I have decided to crowdfund the Purism Librem 5. I am willing to accept a lousy processor (NXP i.MX 8M), low screen resolution (720p), and a low camera quality, just to get a phone that is designed to last 5 years, protects my personal data, respects my digital rights and allows me to unlock the bootloader and install any operating system that I want (PureOS, Linux+KDE Plasma Mobile, UBports, LineageOS or PostmarketOS).

    Here is what a phone should have, but is is impossible to buy such a phone:
    1. Removable battery
    2. Plastic or metal case with thick enough bezels to protect the screen
    3. MicroSD slot
    4. 3.5 mm audio jack
    5. Dual front facing speakers
    6. Unlockable bootloader
    7. Designed to be opened using a Phillips screwdriver, so it can be repaired, not pried apart using a heat gun, suction cups and plastic spudgers, and I shouldn't have to reglue the f*ing thing.

    Maybe add an IR blaster ;). I love my v20.

    LG and its crazy colors...I would feel disappointed the day their displays are not a disappointement. It always deliveries the lulz.

    Non-flagship phone...
    Starting at $620...

    It should be a real pleasure to take that one up the financial backside. I hope LG includes some sort of lubricant with the higher end V50 since the price is likely in the $1K range given how they price out the supposedly more affordable G8. I did just buy an LG, but it was a refurb Rebel 3 from Tracfone for $10 - 5 inch screen, 2GB RAM, 16GB storage, removable battery (oddly absent from anything high end), and if it lives the next couple of years, I'll have sunk a total of $345 into two years of mobile service plus the cost of the handset (300 for airtime, 10 for the phone, 35 for a case, screen protector, and possibly a fresh battery after a year). It's balls out stupid to pay anything more than that for a phone when you could be tossing that money into some sort of interest bearing investment or workplace-funded retirement account so it can compound for you over the coming years. Every little bit makes a considerable difference over a long time horizon.

    poor americans. here in russia i have 100 Mbit landline, 400 min voice + unlim 4G on smartphone - all that for $5/month

    Here in france, you can have unlimited voice/sms/rcs/mms & 60gigs of data (in 4g+/LTE) for just 9.99 bucks (or unlimited data for 15.99€ it depends). So when I look for google fi or other I just fell in apple so much that is expensive xD

    Eh, there's nothing I can do to change the costs associated with living in the US.
