LeaveMeAlone I've had a similar experience with Samsung phones. The S20 has a slightly smaller battery (3880mAh) and a higher refresh rate (if enabled), but I've generally found them to have poor battery performance regardless.
Reducing the refresh rate seems to be the single most significant factor for me. I went to sleep last night with 79% capacity remaining, which was a first!
Hey, I just found this thread and I am facing a similar issue. Coming from LOS on OnePlus 8 (easily 2d+), the battery life on P7 GOS is just crap. I did some adjustments (60hz, seperate some apps to work profile, airplane etc) and now i get about a day and a half. Nevertheless, it feels like a massive downgrade batterywise...
After 50+ installation of custom ROM-s in my life every single one of them had shit battery life first few days, every time! Same like every big update wrecks battery life for a few hours after installation.
I just bought Pixel 6a after using iPhone for many years and I put GrapheneOS within few hours. First few it drained battery super quick, even quicker than I thought it would. I thought that something was wrong. Now I'm on fifth day and battery life is great, just as good as iPhone 13 I own.
Use it a few days and then judge.
I would start with a clean install, and absolutely nothing added.
Use this for a few days, and see if it eats the battery
I can tell you, when I got my pixel 6a, I immediately put GOS on it, didn't even use it for half an hour without. After that I had the phone in airplane mode for a few weeks before I started using it.
I am coming from a 5 year old LG V30 with a 3000mAh battery (original ROM). I used the phone very lightly compared to other people, and charged it once maybe every 4-5 days on average in these 5 years.
Comparing the two of them in airplane mode (even though I didn't actually test with careful attention) I felt that the LG one actually lasts equal or maybe longer. That's just ridiculous. This is WITH GOS on the pixel which means it probably uses less battery than default.
So, indeed I feel like this is the worst battery life I've experienced on a any phone ever. The Tensor is really garbage in this area.
Also yes, the cellular network connection double the battery use. Wifi doubles that too.
I'm a light user, but I feel if I was the regular user who has their wifi and bluetooth on all the time and actually "uses" his phone for "things", then this phone won't make it a full day.
Just a note, the battery will live longer than 500 cycles. Just treat the battery right. Read this post.
pixel 7 pro with latest graphene OS terrible battery life, is there any way to disable tensor chip or whatever causing the battery drain?
stock rom lasts 2 days, graphene os 12 hours
grapheneman You're doing something weird, because most people observe the opposite. GrapheneOS is way better on battery. Especially if you do without the gcrap.
i only compared with a fresh stock installed google rom without any apps and now graphene os with 2 profile. I have a question on this actually. I installed google services into the 2nd profile, do these apps consume any power when i dont use this profile? I test now using only the owner profile which has only 2-3 apps like signal. I dont need second profile often at all, 3-4 times per months for bank apps, but do these apps active even if i dont use this profile?
grapheneman just close the profile, not change profile. End session. That way no, it won't draing battery.
alex_herrero thanks i was not aware how to use the profiles from battery point of view. I am new to Graphene OS. Of course I highly recommend it.
grapheneman
You were using same features in stock OS and GOS ? (Carrier network (3G, 4G), WiFi, VPN, social apps, profiles...)
Hat the stock was really empty and unused, only the google account was created. wifi and 5G on. The graphene had more apps like 5-6. The Pixel 7 Pro is always a bit warm with graphene hardly noticeable but warm, which means the clock is running in it, thats why it consumes more power. Note i did not use the battery optimization or battery saver option as i really wanted to see how long it last. As i wrote about 12 hours.
sorry ignore my report, i am new to graphene os and did not close some app properly. Spotify was running 5 hours and totally faked my test. Now starting a new test with 100% battery and only main profile, no google services and all apps closed minus telegram and signal.
grapheneman I don't think disabling processor will make your experience better...
tensor cores are needed for Deep Learning, so that Google is able to analyze the content of your photos right on the device besides making fake backgrounds or image editing. Otherwise zero need for Tensor cores. As the new phones come with it, i was thinking if possible to disable it. Probably this would mean some hardware close language tweak. Anyways after my last battery test i am totally fine with the 7 pro as is now, 20 hours battery with telegram and signal without google framework - of course.
