Extremely battery drain on Custom roms with Lollipop 5.1.1 - Shield Tablet Q&A, Help & Troubleshooting

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.

[Q] Help with battery usage / drain, how to increase battery life

Ive searched around and this seems to be a common issue, I tried the factory reset even the htc battery conditioning where you charge fully turn off then another hour back on for 2min off again and charge for another hour with no positive results, I read online some ppl are getting -1/-2 mah an hour I have never seen single digit in my phone.
I included screenshots of my battery drain even adjusted the app to read 1500mah, anything else i missed in settings? Also went into phone information in the Tests menu set it to auto instead of GSM, also with SetCPU I tried underclocking with little change to mah usage, running out of ideas...
Currently its rooted with GingerBreak, and CM7 with #48 nightly installed, any help would definitely be appreciated.
How many hours is your phone lasting on a single charge?
Lately between 5-7hrs one had about 8 and half hours a handful of times
it's true that if you constantly use the phone nonstop like watching youtube, browsing, playing games, etc. the battery won't last longer than 4 hours without getting an extended battery, heck just using moderateley the battery will be about 50% by the end of an 8 hour workshift, but what I found that will extend the battery life with moderate use are these...
1. Turn of wifi, bluetooth, gps, sync. (contrary to what ppl say on this forum I find that wifi eats way more battery than being on 4G)
2 Disable background data. (The only thing I actually need background data checked is to use the android market or maps when I need to, with it off it's a huge battery saver)
3 In settings choose to use only 2G (This will increase battery life 4x and Tmobile 2G is pretty fast, just like 3G)
4 Download Opera Mini (Since you'll be using 2G to save battery you'll want to surf the web with a browser that is super fast using slow connections, and Opera mini is second to none. You can always turn on 4G when you want to have fast video streaming but then you eat alot of battery again.)
5. Install Auto Airplane Mode (you can turn auto airplane mode on when you're not gonna be expecting calls such as at work or when you don't want to be disturbed, hell, if you just want to save as much battery as possible. Since Auto airplane mode disables the radio and data completey which is the number 1 cause of battery bleed with it on from a full charge unplugged you'll still have a 100% when you wake up your phone after a day.)
6 Install juice defender (free is fine)
7 Don't use Lookout Antivirus (I've found Lookout drains the battery quick, if you want an antivirus that doesn't eat the battery try AVG. I prefer AVG because I notice it does not drain my battery like Lookout.)
This has made my phone last more than a day on stock battery with moderate to light use. If I think of more tweaks I'll add later
This is ridiculous. If you have to turn off all those features, then don't even bother getting a smartphone.
My tips are:
1- Set brightness to auto.
2- Avoid Skype and other apps that usually appear as On going on the status bar.
3- Get rid of any task killer. They actually make the battery life worse. Don't worry about tasks running in the background, the OS takes care of them. If you wanna quit an app, try to look for a quit button by pressing the settings button when the app is on the foreground. Otherwise, just press the back button below the screen until you get back to the home screen (for some reason this seems more efficient than just pressing the home button.)
4- If you don't use IMs, get juice defender and set it to disable data when screen is off. It will turn data automatically on once you turn the screen on by pressing the lock button on the top of your device. Note that this is different compared to auto airplane mode, with Juice Defender you can still receive phone calls and text messages when the screen is off.
Last but not least, consider purchasing an extra battery and/or car charger.
Mine usually lasts for about 12 hours with moderate to high use. Almost all smartphones have short battery life if used heavily.

Yea that's awful. Do you by chance have your brightness set extremely high? And how is the cell coverage where you usually use your phone?
I think all of the advice above is valid and will save your battery. The question is to what extreme do you want to go? I tend to agree with donatello88 that there comes a point when you get so paranoid about battery life that you may as well not have a smartphone because you've turned off most of its features.
Get rid of any task killers, battery monitors, etc. They are simply churning thru clock cycles and that uses more battery. Set email, Facebook, etc to check for updates less frequently. Either use auto brightness or manually set your brightness to about 25-30%. That should b bright enough for everyday use unless your in bright sunlight a lot. Use juice defender if you like. And be wary of antivirus apps. I've heard some can suck ur battery dry.
If you do those simple things and are still getting only 5-6 hours then I'd be taking it back to T-Mobile ... unless of course you're on your phone without ceasing. In that case, what can you expect? Lol
Ok with the tips I just mentioned above, I got a chance to put it to real world test. I caught the bus to my son's grad ceremony and reached there at 4pm ceremony didn't start till 6pm so those 2 hours just surfing the web reading articles and forums I was down to 90% battery. Didn't know how long the ceremony was gonna be so called my sister on video chat using tango and spoke to her for about 20 minutes. Did some more browsing using opera mini set to only use 2g for another 2 hours, my don came out, I took some pics and video of him turned on 4g to video chat again with my duster for about 5 minutes, and after 4 non stop hours of consecutive use with screen on, I'm now at 71% battery life. I'm at the bus stop now on my 12 mile commute home and I'm confident the battery will give me more entertainment until I get home. Awesome! You don't have to believe me, just try out my tweaks and you'll be amazed.
Everyone thanks for all of the help and tips, today was the first day I saw 10hrs+(included screenshots), I had my screen on auto and after some reading saw that with CM7 it doesnt work well so I have changed it down to 20-40% depending on where I am, turned off background/auto sync only turn it on when I need it and uninstalled the app killer I was using also changed a few of the SetCPU profiles.
Im not really a heavy user just wondering if having 3email accounts set to update every hour would be a battery drain too? I mostly text/email during the day and talk about 1-2hrs depending how busy I am at work.
Again I thank everyone for pointing me in the right direction...unfortunately at home I have 1bar to none for service so I do depend on Wifi calling which im sure drains more juice, also at work since it in a high rise not too much cell signal so wifi on most of the day...

Hello risho,
I was having the same kind of battery life... After 3 months of research, I collected all valuable tips.
"Valuable tips" means: tips that do not need constant involvement from your side (you don't need to go switch on/off things, etc..) and also that leave you with a very functional phone (you have location when you need it, you have e-mails flowing regularly enough, etc...)!
With these tips, I am now lasting from 6am to 11pm and at 11pm, remaining battery is 10% at least!
Go and check my thread: [Ultimate GUIDE] Increase your battery life on Android!
Enjoy!

Wifi battery drain

Hi. I'm having a problem. The wifi is draining my battery. My battery will only last about 4 hours of screen on time.
I've already check the power option of disabling wifi when the screen is off. Wifi drains at least 40%of the charge.
I've read other forums but nobody has an answer just yet. I really like this tablet, but it makes me mad just having 4 hours of battery.
Driver problem, an app misbehaving, hardware problem?
What can I do? What should I do? How many of you are having this issue?

Depending on your usage, it is indeed possible to drain battery 3-4 hours. I myself never had that situation but for those who played highly CPU/GPU intensive game along with WIFI had that issue. I usually had 5-6 hours on my routine use which to me seems was not much.
So couple things I believe you should look into.
1. How is your monitor brightness?
2. What applications are you running? e.g. are you downloading on background with playing some game foreground?
Those sort of basic things. To identify whether the WIFI is actual issue or not, one thing you can do is simply turn off the WIFI and do whatever you need for couple hours and see where you at in your battery. If you have 50% drained in couple hours without WIFI on, clearly WIFI is not the issue but if you suddenly get only 20% battery drain from WIFI off, it is indeed the WIFI.
If WIFI is indeed the issue and perhaps you can try Juice Defender but it will only save battery if you are not using WIFI all the time.
For detail, please refer to http://forum.xda-developers.com/showthread.php?t=1805636.
One last thing is obvious, but battery save mode rather than balance mode gave me extra couple hours without sacrifice in my foreground application performance; however, I did notice main screen page swiping or application launch animation weren't as smooth. Almost felt like back to my old Galaxy 10.1 tablet on Honeycomb.
There is actually a bug that makes your battery overview show the percentage of wifi on time as percentage of wifi battery consumption:
-> wifi on 80% of time > shows 80% of power consumption from wifi.
How long do you have your device ?
When i first got it I also thought that the battery time was bad but now ( i have had it for about a week) i get battery drain of 10% / hr while surfing and 14-18 %/hr while streaming video over wifi and 0,5-1% / hr while standby with wifi and sync on.
I have the brightness on manual contorl and when i watch video i change the performance to eco setting.
Hi, thank you for your responses..... This is an update of what is going on.
I am already on firmware. 26, but had the problems since fw. 22
Yesterday I did a factory reset to rule out some mysterious app. The battery issue continued under wifi.
Wifi was still draining between 40 and 50% of the battery. Completely drained in about 4 hours of browsing time in balanced mode and about 40% screen brightness.
I just did another test. I played 2 movies with the wifi off. After 4 hours of screen on time the battery fell to 66%. So the tablet have enough battery juice for 12 back to back movies. That's great, I can rule out the battery.
So far I can confirm that the battery is draining extremely fast with wifi and is not a big showing erroneous battery drain.
4 hours of browsing tine is a joke for a tablet...
Any other things you think I can try?
For how long have you had it? No matter what people say, the calibration algorithms for these kinds of batteries still need several cycles of charging and discharging before they can actually read out any battery level accurately. I easily go for far longer than that on my device -- not that that fact helps you out, I know -- but I thought battery life was worse in he beginning as well. I guess it just needs to settle down a bit. Give it a week.
EIDT: Oh, and....eeehmmmmm.... do not believe the standard Android battery tool. Get yer mitts on BetterBatteryStats and get a few cycles on it, check the readouts and then report back in.
Sent from my ASUS Transformer Pad TF700T
Thanks. I've already installed better battery stats.. While Web browsing battery drains up to 30%/h. I know is too soon to get to a conclusion. I will keep you post it.
Hope there is some firmware update that will fix this. This is Asus 5th tablet (transformer, prime, slider, tf300) I don't want a beta product!
Sorry about the whining, I know that you guys are helping me..
Battery life is really bad on this we need the motley kernel and some custom rooms soon !!!
I am running this tablet on performance and it is still very slow ccompared to my prime I hoped I can wait for the custom rooms and kernels before I sell this tablet i know i am very impatient
i have a tf700 too and have the same problem on wifi I love this tablet, i think we need to find a fix. Hope to hear from some of the smart people on this forum.
The reason for the low battery is this; Asus did not put a larger battery in Infinity compared to Prime.
Both devices have the exact same battery, but since Infinity runs at a higher clock speed and has a higher resolution screen, it drains the battery much much faster.
You can't really fix this with software. You can however lower the voltage with a custom kernel, making slightly improvement....but that'll also make the device unstable.
Just to let you guys know, i have assigned a fixed ip address for my Tf700 and the wifi drain seems to have decreased. I won't rely on the native android battery monitor (mine still says 85% battery drain by wifi). But i have noticed much less actually drain/hour when using wifi with a fixed ip address than not. YMMV.

Hows your battery life?

I got my HTC One Mini yesterday and I'm getting pretty good battery life so far, how is it for you guys?
I'm using jmz's Stock Rooted Odex WWE Rom and Jmz M4 Kernel 9-04-13. I unplugged my phone around 9 AM this morning and it's now 1:45 AM and I'm at 48%.
I installed 12 apps, torrented a 315MB file using uTorrent @ about 600 kb/s, watched 23 minutes of 720p video using MX Player with hardware decoding, watched about 15 minutes of YouTube videos, went on Facebook for about 20 minutes, browsed the internet for about 5 minutes, browsed a forum using Tapatalk for about 15 minutes, made about 5 minutes of calls, sent/received about 20 texts, read a manga chapter, used it as a flashlight for about a minute, used it as a remote for XBMC for about 2 hours, flashed a kernel, and took a couple of pictures, a 30 second 1080p video, and a Zoe to test out the Camera. All of this was over Wi-Fi.
I think I could easily get 2 days out of the battery as my typical usage would be lighter. How is the battery life for you and what Rom/Kernal are you using?
Stock UK Vodafone Rom recently updated with the it's package.
Well...I am sadly unimpressed by the battery. I've had mine now for just under a month and don't get a day.
I use it to surf the BBC website (in mobile mode) over 3g and at other tines WiFi.
I make calls about 30-60mins a day and play a version of bubble breaker.
I can literally see the power drain when surfing the web. This us the single most draining activity...much worse than when I used my desire.
I have configured all power save options, disabled all non essential apps, and ensured the phone is not burning background or unnecessary apps.
Still it goes rapidly. It's a shame but I like the phone so will live with it.
2 days...yes if all you do is make calls. Anything more demanding not a chance I'm afraid. I have tried, a lot.
So it is now 1.10pm and I have 52% and at 9 am I had 100%. No video no gaming but a mix of BBC on WiFi and 3g (i have a femtocell so no burning power while looking for a signal).
Nice phone in so many ways but battery life, in call quality and control, are very poor.
All the best,
Sam
I am planning to buy HTC one mini, Wanted to get real idea of battery life, so this was helpful. Could you laso tell me if that 1GB RAM is a problem maybe once you have 60-70 apps ? I thinking of 2 years life at least so was concerned?

For me it isn't too much of an issue, but they really should have equipped it with 2 GB of memory, 1 GB has been the standard for about 2 years. I have 42 user apps installed and most of the time I can have multiple apps open without any slow downs. Occasionally if I have multiple heavy apps running (Maps, Facebook, Pandora, Chrome ect.) it can slow down due to the lack of memory, but if I close one it speeds right back up. If you read any reviews you'll hear something along the lines of it's stupid that they only gave this phone 1GB of memory, but for most people it won't be a problem which I agree with. I'd suggest trying it out at a local store before buying it. Different people will see things differently, to some the HTC One Mini and S4 Mini will seem slow compared to the regular One and the S4, to others it will seem very fast.
ok guys please keep in mind that your mobile connection eats your power rly ****ing bad. I did a lot of tests with the mini and i'm was even able to get 5days with 25% left. Camera or wachting videos coast a lot of power as well but music is ok that does not need that much power.
Its all about your connections and how good the signal is, so if you want a longer battery life only use wifi.
The device has smaller screen size, lower resolution, half the number of cores, lower clock speed, lower powered GPU, half the RAM, no NFC or OIS. It should get *better* battery life than the full-sized one all things considered, though the smaller battery will definitely even this out somewhat. I wouldn't be surprised if under typical moderate-high usage involving CPU and screen this device should hold out similarly to the HTC One but in standby, etc it will be a bit lower.
Notebookcheck and GSMArena have done thorough battery testing, though notebookcheck doesn't test standby time and GSMArena's standby time testing method is a bit suspect.
Anandtech haven't published a review of the Mini yet but in their review of the Galaxy Note 3 you can see some battery tests they did of the HTC One Mini and it holds out pretty well considering it's not a phablet.
I bought mine two weeks ago. On the first week, my battery just last 10 hours at least and after a few days of experimentation of various settings and process monitoring, I can last 24 hours with still 20% remaining.
My daily usage can be define as quite conservative as I'm busy at work most of the day.
Here's my activities to give you an idea:
Call - at least 3 minutes a day
SMS - least 20 messages a day
browsing via HSPA / 3G - at least 1 hour a day
browsing via wifi - at least 1 hour a day
playing games - at least 30 minutes a day
reading / composing / sending emails - I set this to manual, at least 5 times a day (when I'm at home)

Hope this can help somebody to have an idea.
No matter what the phone, you tend to see battery life tests showing 8+ hours of web browsing battery life. However, real life never matches up to this expectation, with 3 or 4 hours of web browsing much more typical. This is the case with all smartphones - even a device like the Note 2 or Note 3 (albeit with higher expectations to begin with: - a Note 2/3 may tests 11+ hours web browsing but typically get 4.5+ in real-life conditions).
Unfortunately this leads many to believe that their brand new device (or its battery) is faulty. But in most cases this is not true.
I'll attempt to explain the real reason for the discrepancy.
Most importantly, the battery life tests are exclusively limited to that activity or task. For example, fully charging the smartphone, continuously web browsing for 8+ hours until the phone dies. In reality when we use our phones, the phone will be on standby, or doing other tasks, at other times. For example, 8+ hours of web browsing from a full charge is not the same as getting 8+ hours of web browsing over a 16 hour day. Those other 8 hours, even if the phone are on standby, are going to use up some of your battery, too.
The single biggest battery drain of a device is usually going to be the screen, unless you have specifically forced the screen brightness to a low (<33%) amount. At full brightness, a smartphone may burn through battery after only 3.5 hours of web browsing even if it could last 8+ hours at 40% screen brightness (the brightness control is not usually linear in terms of power draw). Review sites tend to standardise on a particular brightness level that is relatively low (the reason for this is often that allows fair comparison with devices that just can't get as bright). The bottom line is that 8+ hours of screen on time at lowish brightness might drop to half that or lower if you let auto-brightness bring up the brightness during the daylight hours or when outdoors, or if you prefer higher brightnesses.
Often, battery life tests will be done over wifi with mobile phone reception disabled entirely. This is not realistic as with a smartphone you're usually connected to a cell tower even while you're using wifi, so that voice calls and texts can still come through. Also, cellular uses a lot more energy while idle than wifi does. So even if you set the brightness really low and do nothing else with the phone, you still shouldn't be surprised that you can't get 8+ hours of web browsing if you also have the phone connected to a cell tower in the background. Some sites will conduct battery life tests over the cellular network instead of wifi, and typically these will get much lower battery life ratings (eg. 4+ hours, even with the same brightness level as for the wifi test).
Bottom line is, don't head back to the shop if you only get 3 to 4 hours screen on time during the day with web browsing. This is entirely normal for *some* usage patterns. You can improve it by:
Disable auto-brightness and set the brightness to a low-ish value, say 30%-40% of maximum. This might be able to double your screen-on time compared to full brightness.
Avoid using the phone much in direct sunlight. For the brightness to be high enough to read in direct sunlight, you'll be burning through your battery quickly, and if you've set the brightness manually to a low level as advised above, you won't be able to read it in direct sunlight.
Connect to wifi (but of course, only if you trust the wifi network to be secure and respect your privacy).
Realise that if you ever play CPU- or GPU-intensive games (most casual games shouldn't fit in this category) then a beefier battery or external battery booster may be a good investment. There's not much you can do about their battery use.
Only after considering the above should you hunt through battery usage analysers and wakelock detectors. In many cases even a misbehaving wakelock that keeps your phone partially awake all day has a low impact compared to having the screen on full brightness for just 20 or 30 minutes.

[Q] Battery life not so impressive...

I find my Z3's battery life not that impressive as critically acclaimed. A lot of people have posted their battery estimated time to be two days or more but for me, even after cycling the battery from 100% to 1% twice I still only get 1 day and a couple of hours more. For sure I can make it through one day with probably a lot left but I'm sure not a heavy user. Dumb ways to die 2, crossy road and wordament are the only games I play and they aren't even that big of games. I don't play them much either, maximum of 2 hours combined in a day. It says the screen takes up most of the battery consumption a but I usually just leave it on WhatsApp and do nothing. HOW??? AND WHY???

Do you really care about some dumb estimations? What is wrong with you all?! My Z3 works for ~2.5 days with like 2 h+ a day of PowerAmp at max volume , dropping to ~30 %... WiFi off (also not available for location, check that in wifi settings), location on precise settings (no wifi obviously), screen time 1-2 h. Projection is just a projection, why would you care? It just takes the average load, so if you turn it on after an hour of playing a game it will show a lower value...
exactly... want it to live a little longer? use the stamina mode.. (helps with screen off and some screen on battery life depending on how u configure stamina mode..)
all in all a very nice phone with a good battery capacity..
im starting to think 3000mAh should be the minimum/standard in every smartphone that comes after the Z3... u can seriously feel the difference compared to older phones with less battery capacity..
u need to learn how to use the phone without keeping an eye on the battery percentage.. im starting to get shocked when i hit 70-60% by the time im off to bed..
yes at days i get down to less than 10% but without keeping an eye on the battery percentage its living longer...
stamina mode on 24/7 , 3g/4g on 24/7 (no wifi) , auto sync on, whatsapp,instagram, twitter and 2 bbms sucking my battery but nothing this beast cant handle
by the end of the day im at whatever percent ... and sot between 2-7 hours ..
(not bragging but i guess i wont need bbs/amplify/greenify/bmw... with how the stock rom is working)
Well gaming will ramp up the CPU clocks/voltage so lower SOT would be expected.

Not sure why he doesn't realize this.... Screen on for 2 hours playing a game is going to use your battery.
I'm having the same issue as OP. Been through around 5 charge cycles so far. I don't play any games at all. Main usage is for WhatsApp, Twitter, Facebook, a bit of camera use and general web browsing. It's usually an even split between being on WiFi and 3G through the day.
I've had the phone for a week and my battery usually lasts around 28 hours (30 max) with around 4 hours of SOT, (with stamina enabled from 50% down) which I'm kinda disappointed by, given how everyone I see on forums posts great stats of 7-8 hours SOT. (Beats the crap out of what my old Nexus 5 was giving me, but still - bought the phone because I didn't want to think about my battery anymore)
Don't know if I just have a defective battery or I'm doing something wrong, but does anyone have any tips, or anything in particular that you do to ensure your battery lasts two days?
I read that the Facebook app is a bit of a hog, but I don't see any flags under the battery usage page, or any warnings in the section that monitors which apps are power hungry. Going to uninstall it and see if it makes a difference. That apart, my screen brightness is usually set at around 35% (with adaptive brightness on) Any other suggestions would be very welcome
Thanks!

Rooted G Flex-2 H955 is draining battery very fast. Any idea why?

Hi,
Previously I successfully rooted LS966 and bricked while flashing ROM (Lesson Learnt) and paid a bomb to repair the motherboard.
I now have H955 - 15B. I successfully rooted the phone via online remote connect help, because I felt it would be cheaper than last time. After rooting,
Debloated mostly all google Bloatware and few system apps based on a list from another discussion on XDA,
Installed Pimp My CPU and reduced to 1230 Mhz
Doze to block background data traffic
Greenify to stop background processes.
This has been quite a versatile combination for me and the battery doesn't drop by even 1% until the screen is on.
Once the screen is on I am losing 1% of battery every 3 - 5 mins.
I am getting a Screen On Time of 3Hrs.45Mins only.
I have also read up on Battery Calibration issue and this is my second full charge - full discharge cycle.
But the battery percentages are still going down at the same speed.
My screen is drinking above 50% of my juice at 100% brightness. I tried to change that few times but it is more or less same.
Earlier it used to be around 15 to 30%. I am attaching current consumption picture.
While I am enjoying a good Stand By Time of upto 12 to 14 hrs, my Screen on Time is reduced to 3hrs 45Mins.
Is this normal?
Or I am missing something?
Is it the way ROM was flashed on old built before rooting because of soft brick while rooting?
Any indication will be of immense help. Many
Many Thanks.
Seems the way it should be. Changed my battery almost a week ago and I get maybe close to 4 hours of SOT, depends how you use your phone, I use it at 80% brightness though and standby time while it's just sitting on the table is days. :good: N.B. Using android 6.0.1, although it used to be pretty much the same on 5.1.1, maybe less standby time.
Also I'm pretty sure Pimp My CPU shouldn't be compatible with this phone because of the kernel and lockdowns. Maybe they've found some kind of loophole, doubt it though.
Also for the battery calibration, I fully discharge every month to 0% and then charge it to 100% while not using it and once it hits 100% it's good to go. Just the way I do it, not everyone does it the same.
Also, I never trust remote help of any kind, who knows what crap they might do, and even though I am an amateur at android rooting and flashing, I've done it myself every time cause I don't trust remote stuff.
And depending if you want root or not, you could use android 5.1.1 15c(although I don't know if the difference between 15b and 15c is that big) with root or android 6.0.1 20c without root. It's rather simple to root on 5.1.1 though, so many guides here, as long as you follow them to the letter.
You don't have to agree with what I've written here, it's just my opinion.

Are you sure you get close to 4Hrs of SOT on a brand new battery because I get 3 Hrs and 50 Mins or so but less than 4 Hrs on a phone which is 6 months old. Never changed the battery. If that is the case then I think I am doing alright. I have seen SOT Tests of phones like Pixel and One Plus T.
I dnt think pimp my ROM has any restrictions. It kind of works smoothly. It helps me cool down the hot CPU also. I have ovecome the dreaded overheating issues of G Flex 2 easily with clocking my CPU.
I have done the battery calibration. But it quite didn't help me.
I went paranoid because immediately after the root I started to observe the battery percentage on the top. And I felt its falling drastically. But on the other end my stand by time has gone upto 15 hrs. The battery doesn't drop even by a single percent until the screen is on. Once it is on it goes down drastically.
I think of the battery calibration as kind of a safeguard, it's not a necessity.
The pixel and oneplus are different beasts altogether.
Also, as your phone is only 6 months old then it's battery should be ok and as I stated before battery life depends how one uses their phone, I tend to play a few games here and there with 80% brightness and such so it takes a bit more on my end. I personally haven't seen over 4 hours of SOT with my phone ever since I've had it, but your mileage may vary.
As for the PIMP my CPU, if it works for you good, I personally moved over to 6.0.1. When I was changing my battery I removed the motherboard out of curiosity to see how the thermal pad is and only one edge was touching the frame, so I added some Arctic MX-4 thermal paste between the frame and thermal pad and the temps are surprisingly better now. Still tends to get hotter than it should but throttles a lot less now and the screen brightness doesn't forcibly drop below 80% now, even when gaming. It used to drop to 50% etc before when just browsing the web. Anyways, that's that.
It might be some background stuff eating your battery too if you had better battery life than you do now, or it might be because of the motherboard change. Unfortunately I'm not smart enough to say for sure. Also, the more you look at the battery percentage the worse it looks
Sincerely,
Azure Potato

Pixel is too expensive for me honestly and I am not really into expensive phones like iPhone or Pixel.
I am quite happy with G Flex 2's performance and I was only worried about SOT of 4 Hrs. I re calibrated battery and discharged and charged again 100% Thrice.
Somehow battery last over 15 hours after rooting. For example, its 3PM and I have 70% battery left even with SOT of 90 mins of movie. That is 1Hour30Mins.
And you're right, the more you look at battery. the more complicated it gets :laugh:
After rooting - Greenify + Pimp My ROM + Doze + Uninstall System Apps - combination is giving me 15 hrs of usage per day. It more or less includes phone calls, WiFi browsing, Network Data Browsing, Some videos and crazy amount of Twitter, all put together through out the day.
But I am still interested in SOT per single charge.
Interesting.... Same problem here
I'm on 20A, 6.0.1
You're sitting on about the expected SOT. I get anywhere from 4-5 hours and almost never take my brightness off 0%. I'm running a fully debloated 15c setup, same as yours except a version increment higher. The most intensive thing I do on here is install new apps, no gaming or anything. If you have the Facebook app, try switching to Facebook Lite which you can download off APK Mirror. Does everything the normal app does but without all the bloat, it's only a couple MB. Apart from all the tweaks you've already listed, there's not much else we can do. I've always wondered why screen takes the most battery usage by far, maybe it's just the screen type we have. Screen off is great, I lose less than 3% every night including background updates. Screen drains at about the same rate yours does.
