Hello,
I have a problem with my Nvidia Shield K1 tablet
Running system: Lollipop 5.1.1 (downgraded from 6.0.1)
ROM: Carbon 5.1.1-UNOFFICIAL-20160809-1925
Kernel: from the above rom
I've brought this tablet as used and it works very well and smooth,
but when i just want to browse the web, watch some youtube videos or play some emulator games
i can see the battery draining very quickly, with simple web browsing and youtube my battery is draining with continuous use in like 4-6 hours (100% to 0%),
my question is is this normal?
1 time when i used some battery info apps from the playstore it once stated that my battery condition was "bad" when i had like 5% charge left, but never saw this again.
I've also tried to disable 1 core so it will run on 3 cores, down clock both cpu and gpu by a couple hundred Mhz with Kernel adiuator but somehow the settings jump up and down.
This battery drain is on marshmallow, and lollipop both on stock and custom roms, even after restoring stock rom.
Can someone say what is a normal battery duration with continuous use of the tablet? a rough estimate will do, i'm just wondering if my battery is defect or something,
also overnight it will drain like 7-8% if not used, i dont know if that's normal too.
Or can someone help me with this issue or a way to pinpoint the issue?
P.S. i've also applied multiple doze applications like Greenify and disabled most of my start up applications at boot, battery stats don't see any unusual wake locks either.
Thanks in advance for the replies and help.
First of all, it depends on the brightness of the screen. The higher the brighteness level the higher the battery usage. Second, if you play games or stream HD videos 4 to 6 hours is normal. Just browsing the web, word processing and office work should give you easily +9 hours.
Did you deactivate **Adaptive brightness** under **Display**?
Because no matter the ambient lighting, it's always too bright! Manually is the way to go.
Last but not least, is **app optimization** off? If not, do so. It only slows down the performance and drains battery.

Thank you for your response, and yes i have my brightness on manual as overday i like it at around 60-70% brightness and at evening/night i use 5% with a screen filter app to darken it even more which i like for my eyes.
I play emulator games sometimes but if i do i wont get 4 to 6 hours i can get around 2 to 4 hours max, as with browsing the web and office related stuff i have never seen it getting 9+ hours, the max i would get and i tested it several times was around 6-7 hours max, do you have any idea why this is?
I haven't tried disabling "app optimization" but i will sure try to disable that option and hope for more battery life
Could it also be that my battery is worn out/kinda dead as i've bought this tablet second-hand and not new?
+60% brightness that's something. My brightness level usually won't pass the WiFi symbol at daytime and when I game. So it's something like maxi 20% to 30%. And at nighttime and dim indoor lighting it's on 0%. I've to assume that's why I get more on screen time.
Haha, I'm used to darkness.
Either way, I highly recommend a 10k powerbank to double the time.
Moreover, WiFi takes a lot more battery than the Nvidia battery stats show! Just tally up the percentages, and it'll never add up.
The other day, I was streaming HD vids, playing some games, browsing the web and after +5 hours my battery was at 5%.
Most days, I work offline and I get way more on screen time.
I've heard that the display doesn't come set to wqhd+ out of the box. Do you think setting it to this will cause a huge battery drain?
If the S7 and S7 edge are any indication, it should knock about 30 minutes off of its usual 14-15 hour estimates.
The main reason, IMO, not to use QHD+ is that it's pretty much useless for every day usage unless you're using VR. And if you're using VR, your battery's pretty screwed anyway, lol.
Don't you wish thy we could hear from Samsung about this directly. Argh

I hear the new display are more efficient than the S7 displays according to DisplayMate. FHD and QHD+ doesn't have a big difference on drain either.

That's true, also a more efficient SoC and new battery tech that should hold charge better over time. It should balance things out. Software optimisation also helps.

this has already been discussed in another thread.
independent results put the SOT battery life at 42 minites MORE than an S7E, and i believe the tests were run at QHD
S8 Plus battery drain
Hello,
I am using S8 plus (Exynos) with dual sim.
SIM 1 -GSM only- totally for voice calls
SIM 2 - LTE only - totally for data and rarely for calls
QHD+
Location Off
AOD ON
Bluetooth, NFC , smart sensors etc- OFF
No apps run in the background.
I do not use power saving mode.
Moderate user - Mostly texting, Facebook, Online games, Youtube, sometimes reading.
The stats show around 24 hrs remaining after a full charge.
The SOT experienced is around 3 hrs- 3.5 hrs which I think is less, considering that I am not a heavy user.
What I want to understand is, why are some users reporting ridiculous SOT (7-8 hrs) even with heavy usage?
Am I interpreting these stats incorrectly? Is my battery not good?
I have tried to clear cache partition, even formatted my phone sometime back, but still, it hurts to see a lower SOT and battery draining rapidly.
I don't intend to troll, just clearing my doubts.
Kindly suggest.
Thanks
Sahil
You should probably start a new post since this thread has been inactive for a few months and is specifically about battery drain and resolution settings.
On a side note I'm in the same range you are, my cell reception sucks at work so I'm assuming that's part of my battery drain too.
Are there people out there who mostly use their OnePlus 6 with WiFi yet your phone is mostly idle?
What's your average WiFi battery drain? Could you please upload your main GSam Battery Monitor Screen?
My phone is connected to a WiFi router (2.4GHz 802.11n) and the signal strength is excellent. On average my OnePlus has a 10 mAh discharge rate which is several times higher than for my old Nexus which is connected to the same WiFi network.
Here's my data:
20% of 50% of battery used for 31.5 hours.
3300/31.5*0.2*0.5 = 10.48 mAh.
No one uses OnePlus 6?
Actually, people don't left their phone in the corner for days, so you know, you never know.

I use a PC up to 16 hours a day. Not everyone is obsessed with Instagramming or twitterring. I only use my smart phone when I'm en route and I occasionally use instant messengers.
Those who've replied < 6mAh, could you show your GSam screenshots, please?
What type of WiFi router do you use? What WiFi standard? Do you have MiMo enabled on it?
If you rock your phone with that minimal usage, I recommend using ElementalX kernel and LKT magisk modue with battery profile, I'm getting way more battery with this setup compare to stock one (about 4 more sot). But you'll get 30% more lagginess

I wonder how a custom kernel might help with the WiFi module battery drain. I barely receive any notifications and according to GSam my phone is in deep sleep mode most of the time. There's something else wrong but I've no idea what exactly.
Why does no one post GSam Battery Monitor screenshots?

Cause no one use their phone like you do, and it's pointless to measure your phone for fun.
BTW, as you describe, you may encountering oneplus most famous problem, "super deepsleep". You might wanna turn off battery optimization of your apps which send notification and turn off all advance battery optimization (deep optimization, sleep standby optimization).

Here:
Battery Saver: OFF
Adaptive Battery: OFF
Battery Optimization: Not Optimized Apps: None
Advanced Optimization: Deep Optimization/Sleep Standby Optimization: both OFF (I don't want to enable these two because I'm afraid I will start missing notifications from apps).
Am I missing something?
Edit: what's specially funny is that the guy who posted OnePlus 6 battery optimization guide has the same issue though he doesn't admit it. If you take a look at the screenshots he posted, you'll immediately notice that his WiFi usage is the second worst battery offender after the screen.
I still wonder why almost no one cares.

Hi, i think i have a problem with my s10e, and not only me, as i googled. My battery life is draining same when using and not using, phone are in pocket. Why? Maybe anyone know a fix?
I get Max 5h SOT.
Aon on.
Latest update installed.
Phone goes to deep sleep(cpy spy shows that)
Double tap to wake on.
Sync on
Wifi, 4g, location, bluetooth(watch connected)
Dolby atmos on.
But tried everything turning off except wifi, 4g, bluetooth and location, and still no improvement.. heres a screenshot of my battery diagram.
Overnight loses ~15%.
I seen that other users on s10 exynos are getting a lot better battery life, but also many of them also getting even more bad battery life than me. My old s8 even getting better SOT with New One ui.
And my usage is in my opinion light, only internet, whatsapp, facebook. No pubg, no any of that... Is it normal and i expected more from s10, or someghing is wrong? ---Cant upload a screen shot. I got 23% left, phone stand by time 9h 9min, ant SOT 3h 34min..

Same here
Me too. Phone seems to drain a lot while I'm not using it.
Already under discussion here: https://forum.xda-developers.com/galaxy-s10e/how-to/s10e-stand-battery-drain-t3913705
After changing the launcher to nova, battery life significantly improved.
Hi,
I read several posts where people talk about 7..9 hr SOT I start to doubt about the quality of the battery inside my pixel 4a.
Mine is usually depleted around 4hrs, no special apps no gaming only browsing, some YouTube, spotify nothing special. Most of the time using WiFi and good/moderate cell phone coverage.
I already disabled screen notifications, AOD display.
And not sure what else I can do to improve the standby time.
Any tips?
30wakups /hr seems a bit high?
Makes no sense to discuss alarms/wakelock/wakeups in the context of SOT. Besides, the former has little correlation to overall battery life with modern Android builds.
Panel brightness is generally largest variable in perceived battery life which is one reason comparing SOTs is problematic unless that variable is controlled. Consider your settings to see if it's a factor.
Radios (signal strength) and CPU are the next biggest consumers. SOT will almost certainly be less for active gamers vs casual browsers. Connected devices (eg: fitness band) can also take a toll. Make sure GPS receiver is only on when needed. A dirty finger scanner or stuck proximity scanner (rare) can be huge drainers.
If all that seems 'normal' the you may indeed have a bad battery. Device should be under warranty; reach out to Google or seller for a replacement.

Thanks for your detailed answer, I'll perform a test with lower display setting, although I already think this is not the issue here. Because over the day screen off I also experience battery drain -2,5%/hr.
Any test I can perform to check battery performance?

Ah - that's a different matter. I can easily score idle drain rates <0.2%/hr on my 4a. Biggest culprits for idle drain are social and fitness apps that intentionally evade Android's native power management tools. Verify 'adaptive battery' is enabled and no unexpected user apps are shown as exceptions under 'battery optimization'. Restart your phone in '"Safe Mode" (Google for instructions) to see if the idle drain persists. If still no joy install one of the legacy battery monitoring apps like BBS or GSAM (available in the play store) to see if they surface one or more culprits. You can also post a BBS idle dump in the BBS thread where 'good seminarians' will offer commentary on what may be causing the drain.

0.2%?!? Damn! I always look for and am happy with less than 1%. Crazy. You must get days out of the battery

That's idle (screen off) drain rate with only SMS (text) exempted from what is commonly known as 'doze'. Stock A11 configurations; device is not rooted nor have I gone to any length to optimize behaviors. It's a breath of fresh air after many years of 'tuning' hardware, kernels and ROMs to my liking.
Those running a handful of active social apps along with corresponding notifications will see substantially higher 'screen off' drain rates.
Yes, I can score "days" off a charge if I use my phone sparingly. Typical use is somewhat different; I usually recharge every other day with 30-40% remaining. That's obviously much better than others report because I use my phone only when another option (tablet or laptop) isn't readily available.
I usually use my phone 3-4 hours a day because I work 10 hrs but when I go to bed there's still 60% remaining. On the weekend I charge once a day and use my phone constantly (youtube/reddit) with a remaining 20%. Battery definitely doesn't last as long as my old 7t but honestly I have no trouble with it with dark mode/adaptive battery/auto brightness/ restricting permissions to "only when app is running". Like others have said I'd check your battery health and maybe tinker with your settings
