It's amazing how much we actually use our phones in a given day, especially when we watch "videos"! Rate this thread to express how many hours of screen-on time you can get on the Huawei P40 Pro before depleting the battery.

Then, drop a comment if you have anything to add!

Only 7 hours ? Im averaging 12.5 hours with just WiFi , I got 15 hours yesterday but 5 hours of that was with watching films without WiFi , still had 15% left
12.5 hours? That's insane! Do you mind sharing your settings & tweaks? This phone eats ~10% with screen on and 3% with standby with my regular settings. I do see a difference with or without 90hz, though.

12.5 hours is actually normal. But my settings are 60h, (90hz actually doesn't make much of a difference). I've got several apps disabled too. I always have GPS, Bluetooth, Data, WiFi, 5g Off unless I need to use them. Always on display is switched off. I always have dark mode on.

If I was you I would install Gsam battery monitor and see if any apps are keeping your device awake in the background because 7 hours is way too low

Thanks for sharing, bro. :good:It seems our preferred settings are quite different. I prefer 90hz as my picky eyeballs can tell a big difference :eek:. I turned off some of the bloats (but not all), and I keep wifi, AOD, and data on. Honestly, with my regular settings, I'm not expecting it to last longer than 9 hours.
GSam battery monitor has been installed, but I haven't delved into it. My plan is to adb disable a few H apps and watch the difference. I guess you have tested it out, and I'd like to hear your advice.

I can't see much difference with the refresh rate, the phone is smooth af on both settings ?

AOD will drain plenty of battery. I've uninstalled some apps with ABD too, but I uninstalled something I shouldn't have, restarted the phone and the phone wouldn't boot up so I had to do a factory reset ? be careful with what you uninstall with adb?

I'm on 94% at the moment with 1 hour SOT, been using it for Web browsing and WhatsApp.
With gsam I've enabled the extra settings with ABD which shows wake locks, so far I've seen many wake locks from *alarm* but the maximum wake time I get in 24 hours is roughly 6 minutes which I assume is normal,

I keep my screen on lower resolution too and I guess that's helping big time (I only use full HD if I'm watching a film)

I've also disabled background data for every single app and I've set App lamuch all to manual and the only app I let run in the background is WhatsApp, I believe this will improve battery life by loads

LOL. Happy to hear that 90hz wouldn't hit my battery hard. I'll play with the AOD settings, although it's something I'm really looking forward to moving from my old device. I've turned to a lower resolution too, and I couldn't notice the change:cowboy:. All apps in app launch have set to manual and no background except email and one chat app. This is the bottom line for me. LOL.

Keep awake time is ~7m with frequent screen on/off during my 1d regular use, which I'm generally happy with. I'm planning to take a quick look at the wakelock during a short standby, but alarm didn't rank high (after hibernation, syncloopwakelock and eventloop). (BTW, I really hate it that they disable unlocking bootloader, otherwise we can easily tweak those services:rolleyes:.)

AOD is not good imo, in the long run it will cause screen burn (very common with AOD).
Take a look at my screen shots, have your app launch set up like mine.

Keep awake time seems normal, I get roughly 6mins so no issues there :)

Can you send me a screenshot with your full battery usage? Along with every app which has consumed battery?

Look at my 2 screen shots. Have your app launch set up exactly that. The 3 options need to be disabled along with Manual setting on.

Second screenshot you see has background and roaming data OFF for every single App except Gsam & WhatsApp ?

PS use a dark theme too

I understand that AOD could burn the screen in the long run, but the bright side is it frequently shifts the bright pixels and is automatically switched off in pocket/face down:rolleyes:.

Yeah, I have almost identical settings as yours since yesterday. I'll give it a shot, and upload the results. Thanks again, mate.:good:

Sorry to bother you again. I did a quick test using gsam battery monitor. It's not a full cycle, but representative of my daily use. I did not see a huge impact by low resolution probably because the automatic resolution takes care of it in part of the scenarios. Since the Google play services takes the most of the battery, and the other apps have been pretty much limited, I have no clue of how to damp the wakelocks and improve the battery life further. crying:

Hey, I'm not sure why your Google play services battery drain is so high ? if you scroll all the way to the right you'll be able to see what app is causing the drain. The only part I could see was com.Android on your last screenshot.

Best thing to do is find the wake lock names and use adb to ignore the wake locks,

I totally forgot about that function in adb shell. LOL. That issue with google play services got fixed by clearing the cache. After that the battery life was improved a bit (8~9 SOT), and I'm happy with what it is now. I'll keep looking for the culprit and play with the adb ignore commands. Thank you for your help;)!

Which cache did you clear? I want to clear it too to see if there's any improvement. What cache was it you cleared?

I'm glad you're battery has improved ???
Let me know if you find any culprits please and if you find any other ways to improve battery life ?

I believe I cleared the cache for google play services and framework, and please note that don't mess up with the data of framework.
So far my device is running very smoothly, and the majority of alarms come from android heartbeat, and a few from GCM-related intents, so I'm happy with it. I'll have a full battery cycle run and see if I have any improvement. :highfive:

Understood, I just cleared cache too. I will continue to inspect and debloat, will let you know of any improvements or fixes for better battery life, thanks!

Gave you a like too ?✋

One thing that I forgot to do, which may explain why I had some surprisingly high usage of google play services, is to turn off the auto-updates in google play store, although I don't think it has a big impact on the battery. Overall, the battery life (see attachment) looks good to me given my settings and everyday use.
It's kinda surprising to me that the bloatware from Huawei kept silent whereas google services rang a lot of doorbells. Don't know why, but I figure google has reached its hands to too many hidden areas in my device whereas Huawei is still learning from his big brother. Just kidding:laugh:.

I already turned off auto updates ? and your stats looks very good! 3 hours SOT with 70ish percent left, that's very good.

Juding by sales, looks like huawei will be the bigger brother soon ??
