Absurd battery consumption?

Hi guys.
My phone has 9 months. I use liquidsmooth 4.2.2. .I flashed a 3.0 kernel seeking a better battery life than 3.4. But I feel that battery still draining too fast with screen on! For example : I always use battery bot to show a prediction about battery life ; when the phone is deep sleeping it always show good reports ( like 1-2 days left or even 3 , with 80%+ battery level). But when I'm using the phone for 25 minutes straight, it shows 2-3 h left (even with 85% let!).
With every rom this happens .. cm9 , monster, touchwiz5, liquidsmooth..stock.
I had to recharge my phone 2 times today .It seems it is getting worse, but on deep sleep it still lasting long..
I dont know if my battery is bloated , it seems normal to me, I will attach a photo of it later..
About screenshots:
>On the first antutu test it scored 179 but appeared a 0 first,I think it was a bug. On the second, 214.
>First was when the phone was idle for a long time.
>Then after some usage lost some battery and had a bad prediction
>The last one is absurd .. I was just messaging on whatsapp using 2g to save battery
Could anyone help please?

Dude, I don´t know what you are expecting from this phone and it´s battery, but don´t expect to last with one charge for years while the screen is on or your background LEDs to recharge your battery while they are turned on. The LEDs are consuming most and the phone can last up to 4 hours use while screen is on by using a new battery. You should read the specs in your manual instructions. Beside this your screenshoots are telling me nothing because I can´t see how long your screen keeps to be turned on. So with just screen on expect your battery to be discharged within 4 hours and if you are playing all the time with your device, expect it to last even shorter.

Is that on manual ?Ou phone lasts 4 hours with screen on at max?
On those screenshots I didnt play anything .. only using the whatsapp. My brother has a xperia u and while my phone got 100-15% his was still on 70~ .About the same use..
Okay ,I'll get screenshots of screen on time . But one of the reasons I started the topic was that continuously using screen, the battery drops too fast. Eg. : using eventually/little the phone , it lasts more than a day with screen on time about 3:30h. Using it a lot , it lasts 10-13h and screen on 1:30~
I do expect something better than almost 1% per minute. Is that really normal? That what happens if I play anything , battery just disappears really fast.. I did a test now with Dr. Driving.

Might be your battery is already faulty and maybe even getting bloated. I also suggest to check how often it keeps awake in settings->battery.
There are some tricks to incrase battery life like using some apps, disable syncing with google and facebook and battery friendly kernels, but they all will not fix a faulty battery. The main consumers in this phone are still the bachground LEDs and WiFi.

The battery shouldnt spin on a plain surface right? Well.. I tested here..it spinned a lot. Although it doesnt looks fat ...
On the screenshot ,only 25 minutes screen on .almost no use and it isnt awake all time . even so , almost 60%
I usually kill facebook process so I dont get instant notifications and sync. I downgraded to 3.0 kernel some time ago but still the same.. :/
Do hou know if this battery is good? http://www.ebay.com/itm/PolarCell-A...t=DE_Handy_PDA_Akkus&hash=item5649a70c31#shId
I couldnt find someone here using it. Seems legit.. Not one of those 3000mah ' gold 'xD

I bought this battery since my "origninal" one bloated after about 9 month (and got useless).
The Polarcell 1600mAh has only little more power than an original, but for me it seems to last a lot longer.
Been using ist since march, still no problems.
Shipment (paid with VISA) was in 24h.

Yes, this battery will do it fine. About your drop in your first screenshoot. Seems like your UI crashed and your phone rebooted. And yes, your WiFI is all time on, so draining your battery very fast.
Not sure your battery is already faulty, but the spinning is a sign it´s getting already bloated, even if you can´t see it with your own eyes.

My 'screen on' time record is 7h 34m with hurtsky's kernel v4.1 with 61-3xx mhz -I wrote xx because i don't remember frequency

Yeah.. I always let WiFi or 2g on because everyone i know uses whatsapp .. But still, every other phone lasts much more than mine.. Maybe the battery is really faulty.

I have 2 originals Samsung battery, the first came with the phone and got bloated, the second one I bought on a store and it's working great. My battery life was about 6 hours, and now is 14 hours.

Should I get this phone?

Guys,I'm thinking of buying this phone.I think the specs are great but I saw many reviews of it being laggy and slow on lollipop and other issues such as overheating and terrible battery life.
I know that it has a qhd screen which will drain battery more quicker but i saw screen on time of 1:30 - 2:30 hours only which i think is really bad considering it has 3000mah battery.
So guys, is it really bad on lollipop?I don't know if it is better on latest version because i saw reviews from june-july.
I need an honest opinion because I'm really fed up with lag on my xperia sp and now I want a lagfree phone.

the last update (v20U) fix some of the issues with battery, i have 4/5 hours of screen time with all time 30/50% of brightness! lag isnt the problem now, the phone run smooth with last update...really, now i consider this phone a must have, not only for the specs but for this price on the stores! get it, you will be amazed with.

Do both of you have root?And how long it takes to charge?

The phone is a beast, especially considering that it costs 1/3 of current Galaxy S6 or even 1/4 of Note 5.
Battery life is better than S6, in par with Note 5.
Performance is great, camera is great, speaker is great, battery is good, software isn't bloated like Touchwiz.
Only thing that annoys me is slowish updates (because it's not main flagship anymore, G4 is) and washed out blacks since it's LCD screen.
Other than that I think its a great device and I'm happy that I will be using it for another year.

Thanks for the reviews guys.Hopefully i'll get it soon

High battery drain

I bought a new Nexus 5X. And tested it some days.
And I hate the battery. Firstly it doesn't really load when the screen is on (have a look on another Thread I've posted) and secondly the battery drain is very high. When I'm surfing using Chrome the battery percentage is falling rapidly with about 1 percentage every 3-4 minutes, so I only get a SOT of about max 4h. Is it normal with a 1080p and 5,2 Screen? My Moto G 1. Gen were more better than this phone, but it's smaller and has only 720p.
I'm using Android 6.0.1, which should have a bug draining the battery?! Is that right? Is it even possible to Downgrade to 6.0 without unlocking it, because I want not lose my warranty.
What if I Update to Beta Android N? Would there some Bugs fixed?

You should look into this thread:

The gist of it is everyone has different SOT ranging from 3 to 6 hours.

Battery issues

Hey guys , i recently aquired an LG G4 H815 powered by android MARSHMELLOW V20g , the battery drains really fast and i didn't figure out why until i realized that the screen uses up to 68 % of battery power , though i reduce brightness to the minimum , nothing really changes , please help

That is normal. The screen using that much battery is a good sign. The more the better.
On max brightness, the screen uses a fixed amount of energy so if you're using 62% on the screen, it must mean other apps aren't misbehaving.
Tap on the screen and check the screen on time. It should be between 3 hours and 5 hours. If so, everything looks good.

Yes i agree , it's definitely logical , but is there anything i can do to reduce battery draining even a little

Even non root try to disable all non used apps disable sync and gps.
Also shut of data or wifi when not used, Use facebook on the web not the app major batt hog
my g4 normally got me only 2 hours of SOT which is horrible.

It's really frustrating man , and i absolutely deactivated unused apps as well as mobile data , sync and gps , actually everything's off , i made sure of it when i did a hard reset , it's abnormal as a friend of mine has a similar phone , but he hasn't the stupid problem , is there any version i can trust to flash , i have a 6.0 v20g

c'mon guys i'm really out of options

update guys , it's about the phone's battery , when i stopped using the usual charger which was really fast , about 1000 ma according to ampere app , and switched to another slower one , after a few days the battery somehow went to normal , can anybody explain why , was the battery just getting used to the slower charger ?

You should buy a spare battery with it's charger. The G4 battery is not that good even with optimal configuration.
Enviado desde mi LG-H990 mediante Tapatalk

Yeah, well... it's always better to use the manufacturer accessories, in this case the charger. Yeah, we know that Marshmallow uses more battery than Lollipop but the difference is not that obvious if you use the right charger. I've tested and Marshmallow cuts my SOT with roughly 40-50 mins...

That's the real problem , it's when you don't have the original charger , or let's just say you have no idea if the seller would give it to you as the phone was being used , you definitely have to figure out how to pick the appropriate one , any ideas ?

c'mon guys there must be a way to distinguish between a fake and an original charger , for example through monitoring amperage or may be voltage , i just need some clue , anything !

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 Samsung Galaxy S10+'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!

My S10+ battery standby drain is horrible. I hope this can be fixed by a software update. I really hope because I love this device so so... much!!!

Have you restored your data from a Backup?
Which software do you have ASBA or ASCA?
Which version do you have Exynos or Snapdragon?

My phone when i come to low signal areas it consumed an insane amount of battery life. It drains 45% of battery life when screen off 15h with 11h in deep sleep mode, i don't know if that is normal or not but very disappointed, it happened in both ASBA and ASCA, my phone uses exynos chipset.

This will happen as your phone is constantly looking for signal, and the worse the signal is the more it consumes.

Exynos great
My exynos has great battery life with high performance mode always on 1440p... most iv got before is close to 9 hours sot... this pic would be about 8 hours soc because had 15% left

Yes i know it gonna consumes battery life, but 30-35% in 5 hours is way too much, i also check that cell standby only comsumed 5%-10%, so i dont know what's happened, it's definitely not happen on my previous iphone.

I saw that the my s10+ standby drain too much after the update .
I turned off everything before i slept( always on display , auto sync , even bixby routine ), turned on airplane mode and it consumed me 5-6% battery after only 6 hours....
My phone is exynos version .
Does anyone have this problem ? Please help

I've had the same issue the last couple of days after the March update. Losing between 5-8% in 7 hours with flight mode turned on. My Note 9 SD845 loses 2% in the 7hrs. I charged them both to 100% to see how much my Exynos S10+ was losing. I downloaded CPU Spy and I can see that 442MHz is on quite a bit despite restarting my phone... I'm still unclear what the issue is. I might just sell my current device and stick with my Note 9 or perhaps order the SD855 G9750 variant... Hmm

Is my standby good or bad? 6% over night 9hrs. 94% left. S10+ Exynos

Wipe cache partition would solve the problems. I got this solution from a twitter post

I tried this, didnt make a difference.
my standby drain is terrible - max my phone lasts is 5 hours SOT over 24 hours. but even if i dont use the screen it seems like it only lasts 24 hours still - doesnt make sense
