[LG V35 Guides, News, & Discussion] DinoBuaya:
First time when I got the phone, running on the official AT&T ROM these where my results:

That’s a lot, a lot of, WhatsApp calls which drains battery on any phone these days. Apart from that plenty of WhatsApp texting, a bit of browsing and Reddit app plus some camera tests was all I did. So to get 5hrs and 30mins or so in nearly 30Hrs off the charger is something I could never ever even get close to doing on the Oneplus One running lineage OS 16 or the Note 4 running Stock Samsung 6.0.1 Android. The best those phones could do was 4hrs SoT in 12hrs with strong LTE signals around. When the signals were crap the SoT tanks to maybe 3hrs and 15mins, sometimes even less, this all despite being on newer batteries.

Settings were

Screen Resolution - High (1440p)

AOD - Off:

Wifi and LTE are always on – ~60% of it was on Wifi and 40% of tit on LTE bands 3 and 7

Brightness at no more than 34%, not a fan of the auto brightness implementation on the LG phones

NFC – Off (I don’t use it)

Printing – Off

Data Saver on (Data plans here in this region are from the stone age)

Color mode is warm to reduce blue light

Knock ON – On

Location – Off (I turn it on only when I need it)

I was already impressed but I hate the AT&T bloatware that come default and worst of all the need to constantly input APN settings manually each time I swapped SIMs when crossing the border between Singapore to Malaysia (&Vice versa). I knew about the Google Fi ROM so I loaded that up and I then re-did all my apps and used it like I do normally with all my phones.

Day 2, you can see I managed 4hrs SoT with 47% left, only difference being brightness was 24% most of the time, apologies I forgot about the app usage screenshot.

Day 3, was traveling day for me to go back home to KL from Singapore, I took the phone off the charger at about 8:15AM and went to work, the fairly low usage lines at first shows the time at the office, the steeper dive is all on LTE with WiFi turned off. So major part of the usage was on LTE. And I managed 5hr and 6mins with 44% eft in the battery, brightness was at 12% because its dark in the bus.

Settings were

Screen Resolution - High (1440p)

AOD - Off:

Wifi – On only in the office, LTE was On all the time during the bus and in the office

Brightness at no more than 32% at the office, and was 12% all the time in the bus

NFC – Off

Printing – Off

Data Saver - On

Color mode is warm to reduce blue light

Knock ON – On

Location – On (wife frequently tracks me using WhatsApp’s Real-time GPS tracking feature)

I couldn’t drain it out so put it back on the charger, again I forgot to take the snap of the apps used but it's mostly YouTube Vanced, a lot of WhatsApp and with some Reddit app and Browsing in-between.

Day 5 , traveling day back to work from KL to Singapore

Screen Resolution - High (1440p)

AOD - Off

Wifi – Off

LTE- On

Brightness at 12% all the time in the bus and upto 30% when outside for RnR and out about in the open.

NFC – Off

Printing – Off

Data Saver - On

Color mode is warm to reduce blue light

Knock ON – On

Location – On (wife frequently tracks me using WhatsApp’s Realtime GPS tracking feature)

I reached my room in Singapore and took a snap of the battery stats:

Day 6

Continuing on from where I left off the night before:

Screen Resolution - High (1440p)

AOD - Off:

Wifi – On

LTE- On

Brightness at 12% all the time in the bus and upto 30% when outside for RnR and out about in the open.

NFC – Off

Printing – Off

Data Saver - On

Color mode is warm to reduce blue light

Knock ON – On

Location – Off

I lost only 2-3% overnight on Wifi (sleep time). Now the brightness is back upto 32%, I have added the progress through out the rest of the day till I reached about 9%

So to end with 6hrs and 30mins of SoT for my kind of use well into the next day is pretty impressive. I was really skeptical of those 7hr - 8hr claims seen in here for the LGV 30+ even though on WiFi but now I buy those claims totally. It really is possible and the key here, as far as I can see, is the brightness of the screen. My eyes are sensitive but I can see well even at these lower regions of the brightness on this phone. I just can’t imagine myself ever using maximum brightness indoors under any conditions, even outside I use it only briefly if some important messages come through. Most of the time I can manage with 34% brightness even under sunny outdoor conditions. I wear glasses so am not having above average eyes by any stretch.

I needed a phone that is truly all-day for my kind of usage, I didn’t think the LG V35+ could cut it but at the price of USD 350 off of Amazon, brand new, it was very hard to pass up. I took the risk and got a brand spanking new unit and I am very very very pleased with it. I guess most phones of 2018 and later might give this sort of battery life because technology has progressed so much since late 2015 but the sound on headphones though its DAC combined with the SDcard slot just makes it an outstanding phone. Imagine what it can do with 4000mAh. LG has done an amazing job with its BSP software to get this kind of optimization for battery life. Even my wife’s newly battery replaced S8+ can’t do this sort of endurance no matter what kind of usage gymnastics she employed to stretch it out.

Even at 30-32% brightness all day long I think this can give 6hrs of SoT easy with some 20 odd % left to spare if I continuously keep using it with decent LTE signals around. The route inside Malaysia after the immigration checkpoint has very spotty cellular coverage for at least 1.5hrs worth of driving distance, even then the drain was very normal like there was no real singnal issue at all. Impressive modem firmware at work there.

All in all I am mighty pleased and I hope to hold on this phone for at least 4years with a fresh battery swap somewhere midway in that time frame. I held on to the Oneplus One since October 2014 until now so that's no problem for me as long as nothing major fails on the phone, my Oneplus One's screen is now getting artifacts on the lower portions of the screen while scrolling through images and certain apps. Some sort of capacitive interference from the now failing capacitive touch buttons.
