Lollipop.. Amoled.. Battery life - Galaxy Note 4 Q&A, Help & Troubleshooting

Would lollipop have a much better battery life if there was a dark theme (as opposed to the new bright color scheme.)if you get for example 5 hours screen time would it go to 6 or 7 hours? As you would be lighting up the screen way less?

[Q] Battery life is terrible

I have the BLU Studio 5.0 C HD D535u. With light usage, the battery doesn't even last 1/2 a day without having to be charged I rooted the phone with kingroot, and removed some of the bloatware, but does not improve battery life. It seems that just having the screen on drains the battery immensely. With screen off there is no drain. Any ideas?
the screen's minimum brightness is still really bright. I downloaded an app that lowers the brightness even lower than the minimum(Dimly), and I can go through a day now, with average usage.

Screen on time

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 Moto X4 before depleting the battery.

I'm getting 6+ hours and true all day use, easily.
Easily the best SOT of any device I have owned... Over 6 hours yesterday and was at 45% when I plugged in for the night. I don't believe I will need to charge this thing at all other than overnight. Amazing!
Crap I'm getting 4 hours at a stretch.

The X4 has a bad cell reception. On wifi i get 7-8 hours but in mobile data only 4h maximum
I was off WiFi yesterday traveling and still had nearly 7 hours SOT by 10pm and 12% battery left. I live in rural Wyoming.
I'm at 3.5 hours SOT, and I'm still at 43%. A good bit of that was relatively intensive. I had GMaps download 3 offline maps covering 5 states, Play Music downloaded ~3GB of music for offline. I logged in and set up a bunch of apps (social media, etc), and played Clash Royale for ~1.5 hours.
AccuBattery says I'm averaging 11.2%/hour Screen On, and 0.7%/hour Screen Off.
Clash Royale is ~13-14%/hour, where both my old Nesux 5x and Nexus 7 (2013) were ~25-30%/hour.
I am extremely impressed with the battery life on this. I can't wait to get a kernel with hotplug and root with Greenify to see if I can't get it down even more.
Update: Over a 36 hour period, I got 5.5 hours SOT, and plugged it in with 12% left. That includes running benchmarks, playing games, and all the stuff I mentioned in the previous post. I'm guessing I could get 7-8hours in a day of continuous light usage, and probably an average of 6 hours SOT with a generous mix of gaming and youtube thrown in.
Overall, I'm VERY happy with the battery life.
Had 4:40hr sot at 51% battery

Background color
Can anyone help me with this question? I read that an LED screen will consume slightly less power the "whiter" it is, unlike AMOLED. So I've been changing all of my wallpapers, backgrounds, etc. to white/light to help the battery life. Could someone add to this with some facts?

That is false. OLED or AMOLED screens are made up of thousands (millions) of tiny LEDs, so black backgrounds save power by simply turning off a portion of the screen when it wants to show black. This is why you get battery saving.
The screen on the Moto X4 is a LED-backlit LTPS IPS LCD. Because the backlight is separate from the LCD itself, and the IPS LCD is an active matrix, there's no way to reduce the power consumption simply by changing the color. The IPS LCD has to use power to change the color no matter what it is, so it's kind of irrelevant. The only change that can (and WILL) make a difference on your battery life is brightness of said backlight. This is why everyone knows to lower your brightness to save power.
If there was a way to segment out the LED backlight into a per-pixel basis, then you could obtain the same battery saving features as an AMOLED screen, but at that point you're basically building 1/3 of an AMOLED screen anyways, so why not just build the whole thing?
An interesting side note, because these phones are using LTPS technology, the LCD itself does use less power than older phones, even at the same resolution. It's still dwarfed by the consumption of the backlight, but power saving is power saving, amiright?
wow, this sd630 is awesome! getting 6+ hours with some heavy wifi downloading, installing apps, making a hotspot, streaming music, watching videos, etc.. why did i ever want a flagship?? my old op3 couldn't get close even underclocked and with a black substratum theme lol
battery life is crazy on this phone. what did lenovo/moto do?
i can use it for social media and some gaming and I'm always on 4g and theres days when I dont charge it at all. loving it.
I got 6+ hrs SOT on 1st day let's see how it's perform in next few days
I am getting 8 hours SOT with moderate usage. However I am using data over WiFi only and no gaming.
battery life is great here as well.
even with 2.4ghz wifi (being at reasonable distance from the router),
browsing on screen time with speakers playing music but not on loudest,
i seem to be able to hit 10hours easily.
best phone battery i've had. (compared with Samsung SII plus & Moto g3rd
(I don't play games on my phone tho so i can't comment on that)
i'm a heavy user but only play Marvel contest of champions on my phone sometimes. Mostly i play youtube videos on loudspeaker with maximum volume, check facebook, twitter, chat on whatsapp etc. And i'm still getting nearly 6 hours of screen on time!
I don't track my SOT but definitely impressed with the X4. I normally charge my phone (and remove the charger) before going to bed (12mn) and until now (it's 2pm here), I still have 60% battery left.
I don't play games but I frequently use my phone for social and media consumption.
I'm not worried that my phone won't last til I go home (~10pm).
With my previous phone (HTC 10/ Huawei P10), the battery percentage may be around 40% by now.

1hr 30 mins of sot left with 64% battery
48mins of gaming
Battery saver on the whole time+720+60hz, on wifi+cell, web browsing+streaming, music, vids, txting, few games, 9+ hours SOT.
GF's phone, ton of gaming/txting/fb/web, battery saver only turned on after <10%, 7+ hours SOT.
SOT is good not great but that is at 120 1440. I easily make it through the day so why change it.
This phone has amazing SOT! I'm sitting here 13hrs in, 37% battery remaining with 6hrs screen on so far.. Lots of browsing, some Lineage 2, and an hour or two of music streaming so far.. That's with bt/wifi/lte, auto brightness, max resolution and refresh rate. Just using stock without any battery saving stuff.. Alot nicer then my 6p for sure!
Its amazing i was watching episodes on netflix after 5 hours screen on time 62% of battery left.

Hi! I have a 6P and I'm on the fence about this phone. I absolutely love that it has a higher refresh rate screen, massive battery and lots of RAM. I love my 6P but the battery life could be better and the Ram management is terrible( my biggest grip). The lackluster camera on the Razer doesn't reeeeaally bother me as I don't take many pictures but how does the max screen brightness compare between the phones? If they are relatively similar that's great because I'm happy with the brightness on my 6P. Thanks for your help.

It's more than enough.. Especially if you turn off auto-brightness it gets very bright! I run my phone dimmer cause I like it, but it gets very bright, not sure what all the criticism was about.
The camera is lacking features and the quality is still average at best, but if you use one of the google/pixel camera ports it helps with the quality.. I really don't find the quality that bad myself, but the missing features definitely compared to the opengapps one.
Best so far I've had.
Average around 6hrs. In my opinion best battery life I've ever had on a phone.
Resolution @ 1440p
Refresh @ 120hz
That is amazing specially if flagship devices cant even do half of that in most cases.

OMG, don't get me started on the s8.. lol
Resolution 1440p
Refresh 120Hz
Brightness ~35%
Ambient Display Off
Adaptive Brightness Off
Night light Off
Build number .853
SOT ~8hours (2hours of which was Maps in the car.)
~10min voice call
~2hour WhatsApp call
Quite unprecedented since my many years since day dot with Android.
As good as the SOT is, I'm more appreciating how the device deep sleeps - I like that flat line on the graph.
No need to fight with Android ecosystem or any quirky issues preventing deep sleep: the Razer sleeps like a baby (no greenify, battery improvement nor brevent nor lspeed nor sdmaid equivalent apps) :good:
Well done Razer.
Now sort the tiny quirks and smack this out of the park

Nice!!
I am still impressed with the battery management.
Almost 6 hours (last time I checked). So very impressive.
Easily over 4 hours with heavy gaming and app downloading. ... and music playing over Bluetooth all day.
4 hours to 4.30 hours with 1+ gaming (guns of boom) medium settings (1440p 90Hz). good standby drain
Anyone mind posting battery degraded sot results after owning it for a while? Ty

Hello everyone,
I just wanted to share with you the screen on time that I had this early morning!
Well, the screenshot #1 to #2 shows how the battery dropped 3% in 6hrs. from 11% at 5:56AM to 8% at 12:16PM. considering the 7hrs and 50min of SOT is AMAZING! (not a heavy user though).. my usage to phone is moderate as you can see in the battery usage info! The battery has improved ever since I changed the lockscreen & home screen wallpaper to totally black! this helps a lot in preserving the battery life especially in an OLED screen!
Nice results. I have XZ2 and Im considering upgrading to XZ3 because of OLED display (with Android 10 and dark theme it should be even more power efficient). Does XZ3 have better battery life compared to your previous XZ2? Thanks

yes, the xz3 screen is more power efficient than the xz2, much sharper and has an immersive details, and the battery life is more durable too. i've tried the android 10 beta version with it's dark theme 3 months ago, and to be honest, even with it's tons of bugs it looked so cool and fits perfectly in an OLED screen. i'm sure you'll be more than happy upgrading to xz3, and you will notice the far difference in camera and screen quality compared to xz2.. also is more powerful. if you can get yourself the 6GB ram dual variant.. slightly faster and better in term of multi-tasking. i know xperia 1 is still so expensive world wide, but who knows maybe you find a good deal so you skip the xz3 and get one for you!
that would be a great upgrade.
those are some screenshots from android 10 i took them when i flashed it in my xz3.
Thank you very much! I appreciate it! Yeah I would like to get Xperia 1 especially because of that wide angle lens but it's 750€ where I live compared to 300€ of XZ3 so I will get Xperia 1 next year when it's price drops I guess ?
I got 6-7 hours. Think it is not good result

What is your setting to get that

Standby drain

When you sleep, does your phone sleep, or does it stay up all night and crunch 1s and 0s? Rate this thread to express how you deem the speed at which the Google Pixel 3 XL's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.
Then, drop a comment if you have anything to add!
I have been with google phones for the last 5 years.
With the pixel line, I have never been so happy with my battery, specially pixel 2 xl. Battery would last 1.5 to 2 days...
However, with the 3, at the end of the day I had 39%, on a day I did not use the phone except for 10 sms, quick stocks check, 2 emails, no phone calls, 15 minutes of music with bt headphones in the metro.
Last night, I put it in safe mode, charged it. Took away from the charger at 6am, checked emails. At 8am, I had 90%.
Removed from safe mode at 8. Checked some messages, spoke for 10 minutes over the phone, checked emails and stocks. It is now 9:20am and my battery is at 80%
Not good. I am really disappointed.
If you have yours, please let me know how you feel about it.
I did see one youtuber complaining about his battery, I am afraid mine is defective. If not, I want to go back to the pixel 2 xl.
The battery is supposed to be adaptive, so it learns your usage. Most have said it needs a few days/a week before you get the full optimised life for it
Pixel 3 XL Battery Size: 3450 mAh
Pixel 2 XL Battery Size: 3,520 mAh
The Pixel 3 XL Battery is smaller no way around it
I have the XL and I charged it on the first day and let it drain to 1%. It lasted 27 hours and 5 hours and 40 minutes of screen time. I'll take it.
Battery life has been overall excellent. I havent been watching it like a hawk but it lasts all day with heavy usage. A- overall

There is really a misunderstanding about Adaptive Battery mode. All it really does is make sure that poorly written apps can't drain battery in the background if you rarely use them. If you don't have any apps like that Adaptive Battery doesn't really do anything. In my case I have no apps like that so Adaptive Battery on my Pixel 2 XL has made no difference.

I'm curious what kind of use got you that kind of battery life.
If you were using mobile data, had the screen really bright, played games, used navigation, etc that's pretty good.
If you were on wifi most of the time, lower screen brightness and doing non battery intensive tasks that's pretty disappointing.
I would say half and half wifi and mobile data. Screen was at 75%. Lots of web surfing, Netflix and YouTube. 45 minutes of navigation. Light email, texts, calls and photos. No games

I agree with you on that, but...
4 hours and 30 minutes off the charger, 6 days of using the phone:
2 XL: 96%
3 XL: 73%
The percentage here is MUCH larger than the battery size...
I am so disappointed and waiting for my replacement phone. If this continues... welcome 2 XL again...
what %/h (percent per hour) screen on?
i have 11%/h and 2.1%/h for screen on and off, combined 2.9%/h. over night it went from 23 to 17 i think. i charged to 80% this morning and at 39% from 9A to 10P.
The top of the screenshot is the battery life I'm getting at that moment, and the bottom is the average. This is mainly on wifi, with screen about 75% bright, using a VPN(idk if that drains it but seems like it). Anyway, I'm really happy with the battry life of this phone.

This really isn't the case at all. The naughty list of apps is really only one function of the adaptive battery management. Do you really think Google would be bragging about a task killer?

What you said was that it only helps with poorly written apps. That is totally, completely wrong- and I don't believe you bothered to read the article- you would know that.
https://venturebeat.com/2018/08/28/how-android-pies-adaptive-battery-and-adaptive-brightness-work/
See the section labeled "Adaptive Battery: 5 percent reduction in overall CPU". There is a noticable difference with the battery management on the Pixel 2 &3. It takes 2-3 weeks from my experience & it DOES in fact learn and adjust to a users usage. That's why they are calling it AI. You can't just look at one of those battery apps and judge the phone over a 24 hour period, nothing quantitative there. Use the phone as you normally would for a period of time and then and ONLY then can you fairly judge it.
This ties into Google's position on the camera as well, "bigger/more" isn't ALWAYS better. Machine learning can do a lot, and you need look no further than the performance of the camera to see that.
That being said- could the battery be bigger? Sure. It's actually 100ma less than the 2XL this year. But why? If you can get the same performance with "less"- it would be pointless to spend more money on "bigger."

Noticable battery improvement on the Pixel 2 XL? If you had poorly behaving apps then yes. I don't have any apps that hog battery in the background when they shouldn't. My battery life on my Pixel 2 XL running Pie is no different than it was on Oreo. I actually had a huge battery life decrease after I updated to Pie but a factory reset got me back to Oreo battery life.
And a 5% reduction of CPU means nothing. That's so tiny it isn't noticable. It's not the CPU or software that has the biggest impact on battery life. It's the screen and the size of the battery. Software optimizations help a little bit but not enough to even be worth mentioning.
The Pixel 3 XL doesn't get the same battery as the Pixel 2 XL. Not even close. I can do anything with my Pixel 2 XL other than GPS navigation and games and get 7-7.5 hours screen on time over 24 hours off the charger. That's down from 9 hours screen on time over 40 hours when it was new. The Pixel 3 XL isn't getting close to that. A combination of a bigger screen, higher resolution and smaller battery is the reason.
I don't know why people keep making a thing about the XL 3 battery being smaller than the XL 2 battery as though there has been some major downgrade, It is 2% smaller.
That isn't going to make any significant or noticeable difference. If you take a 6 hour SOT that would make 7 minutes difference! If there is a significant difference in the battery life of the XL 3 v XL 2 then it is nothing to do with the difference in battery size.
I too would have preferred a significantly bigger battery but most phone manufacturers continue to ignore this. I know some phones do have larger batteries, like any phone choice, you balance all the features offered and make your choice.
I'm getting 2.5% drain per hour regardless of whether the ambient display is on or not. It also doesn't change if I turn adaptive battery on or off.
I don't get it..

Yeah, this is one decision that Google made that I truly don't understand. Why would you downgrade the battery when you're adding more horsepower to the device?! I can maybe see doing this for the Pixel 3 but absolutely not for the Pixel 3 XL! My only complaint is the battery life, that being said, I know it's supposed to be adaptive, so it may improve over time. I'm hoping that proves to be the case!
UPDATE: I tend to agree with the point another person made that it's a 7% difference, though, I for sure would have preferred it was a 7% gain vs. a loss.

The problem all comes down to wireless charging: the wireless charging coil steals a couple mm of space....that's the only reason why the battery is smaller.
What I don't really get instead is why everyone is so freaking happy about wireless charging...I mean, for a marginal gain in charging behavior, we loose in battery capacity!
The pixel 3 xl drains much faster than the pixel 2 xl. It might be the new screen from Samsung consumes more energy but I'm not entirely sure.
