[Q] Battery Depleting Quickly

I have had my Note 8 for a couple of months and just recently I have been having battery problems. I restored the Note 8 to factory settings (just to be sure) and am still having the same problem.
It seems that when I watch videos or play any games the battery depletes extremely quickly e.g Its 80%, I start to play the game and within 3-5 minutes the battery is 30%. I play again and its 5% and the screen dims (which is also a pain in the ....) I realise that Games and Apps use a lot of power but surely not this much.
I have looked around for battery calibration instructions and apps but are a bit dubious to try them as I have read that you can deplete the battery totally and the device then wont charge.
Just wondered if anybody else has had the same problem.
Thanks.

My note has a great battery life. For this situation I would look in the battery menu for any apps not closing correctly thus sucking battery. Remember to dis activate GPS, Bluetooth and data when not using them. Check the screen brightness is 50% or less. Automatic brightness should be fine also.
here's a lot of info related to batteries. I'm sure you will find it usefull
http://batteryuniversity.com/

Don't waste time with calibration. Sounds like the battery ifs failing or dying, either way it's bad.

I usually have Bluetooth and GPS turned off and have the screen on Auto Brightness. I also restored to factory and the problem still persists.
One strange thing is that when I charge it from 10% it takes about 50 minutes to get to 100%. I thought that was a bit quick. The battery must be reporting the wrong charge to the OS. I wish they had user replaceable batteries in this thing although its probably not practical.
I will give Samsung a call. Cannot beleive it has happened now as I am off on holiday soon to the US and wanted to use it there.
Thanks.

Hi, I've had the same issue. I sent the device for service under warranty and they could not find a fault. They only reflashed the firmware.
Its been working fine since I got it back. I updated to 4.2.2 and its working just fine.

same with me chas0001, and JCUK89, my situation is actually identical to chas0001, but my device is like a mth old now, i received it on august 5th 2013,
so its basically been used for jus over a mth now. and i barely use it, maybe 3 hrs a day, most days less than 1 hr, constant use.
i dont kno, can anyone help. on xda developers. ??

I called Amazon.co.uk (where I bought it from) and they agreed to replace it for me. Its was definitely faulty and unusable. I kept reading about people with the similar problems and so eventually decided to not get a replacement but a refund.
Its a shame really. I really liked the device but I need something more reliable. I also don't care for Samsung with their constantly delayed OS updates. 4.1.2 for a 'flagship' device. Surely if they get rid of that Touchwiz crap they can release timely updates. You never know even my Note 2 may get an OS update this year!
Just went out and bought a Nexus 7 (2013). NOW...what to do with those 5 Galaxy Note 8 cases

[Q] Schould i buy a LG G3? Ooooorrr note 3

Hello,
Im really excited about G3 and i want to buy one with my new contract. But i really hate what im reading about the lag/stutters and the heating battery.
So should i buy one or go for the note 3.
I hope you can advice me.

I'm kind of in the same boat. One of my employees got the G3 (I currently have the G2 and love it but I'm cursed bc my brain thinks I always have to have latest awesome sauce phone. ugh) and his battery life has been horrendous. I'm talking half of what the G2 can do. I know that QHD display will chew battery and all but that seems overly ridiculous. In the span of an hour he went from 100% to 82%. I checked his device for every possible thing that could be causing it and found nothing abnormal. His android system usage is at a constant 47%. I went through apps he didn't use and disabled what I could (he's not rooted. Doesn't really know much about android but I converted him with my constant iPhone bashing =D) without Titanium Backup and from what I can tell it just seems like the stock software of the G3 really isn't optimized all that well for performance v battery life. Nowhere near what the G2 accomplished. It's disappointing bc the device looks amazing but if the phone drains that rapidly for seemingly no reason I am going to hold off until they hopefully release a software update to fix the drain. It may very well be he got unlucky and got a lemon battery or it could be LG didn't put a large enough battery in the device (only 200 mAh larger than the G2) to handle that screen. I'm kind of leery of the device now. I am waiting to see more user reviews of the device. A lot of review from tech sites keep saying the battery life is good but not great. I don't consider a device barely making it through an entire work day with limited use good.

If his android system is using that much battery there's something turned on that shouldn't be. I highly doubt an OEM would go backwards in terms of optimization. Android system could be a number of things like WiFi scanning always on or location reporting on high accuracy.

I have both. Selling my Note 3

Im aware the device shouldnt be throwing those system totals out but it is. Ive checked everything and compared his G3 settings to my G2 (running Optimus G3) and changed literally everything to my setup. Didnt make a difference. Its weird man. Ive never seen system usage like that and then havent be able to find the culprit.

I had a note 3 and the G3 was a big upgrade. Is much better and for me the battery life is better. The UI is much better looking and there is less lg bloat in the system then tw has. My wife's s5 has a baby monitor progress running stock. Who needs this? It's just dumb little things like that that bother me about tw.

I wouldn't mind the heating or lag, the random shutdown on the other hand is really something to be aware of. Happened twice to me this day...:-\

Battery life is great to me. 15-20hrs of standby with 5.5hrs of screen on time.

I've had the G3 since it was released, get almost 2 days or more battery after disabling a bunch of apps, till they get root for the Sprint variant.
Sent from my LG G3

Just FWIW, you can't judge battery life on an occasional dip in the percentage. The battery meter isn't perfect. You'll find tons of people finding that the percentage sits at 100% for an hour and then drops quickly after that. The battery didn't simply not drain for an hour and then start draining quickly, it's the software trying to approximate. Go from full charge to near dead and see what happens.

I get great battery life. Only issue I have is the camera. Pics just don't seem that great.

ASUS tell us what's going on.

This battery drain issue is really annoying. I have tried absolutely everything to fix it. Except unlocking bootloader and rooting. I shouldn't have to do that to get what the phone is capable of.
I sold my previous phone which was an Alcatel idol 3. Not a bad phone, just a little leggy. The battery in that phone was a 2900mAh, it lasted 2 days easy!!
This ZenFone 2 has better specs and a slightly bigger battery and I can't make it 10 hours, a lot of other users who also bought the phone have the same issues. Android OS battery drain.
I have 5 days before I can return the phone to the store ( I'll get charged a 10% restocking fee, which I should send the bill to ASUS)
Can anyone from ASUS tell me what's going on regarding a fix?? Update??
Would making a video about the issue help. ( I have access to some big name youtubers, phone reviewers) it might not help your sales though.
Thank you,
From a guy who feels himself and many others have wasted there money.

I have a feeling that you have a CN sku with WW rom... Am I correct?

I bought it from a store in Canada, I live in Canada, I know it's a ww Rom, what does the cn stand for

Are you running the latest firmware and are you using Google Fit at all?

Yeah running latest updates I'm not using Google fit

Do you still get a battery drain when you use a different launcher? Ie. Nova launcher?

Do you have SD card inserted? I can't use SD card since before mediascanner finishes (500 songs on SD), all battery is drained or phone crashes and gets stuck in bootloop ... Also the mediascan clogs I/O and phone is so unresponsive that I can't turn screen on once scan starts. Removed SD card and phone works again.

To help improve battery life please ensure to turn off 'Wifi Scanning always available.' To do this go to Apps/Settings/WiFi Settings/Advance Settings(menu in upper right corner)/Scanning always available/ turn Off. Please also see the following information showing 8 ways to extend the ZenFone 2 battery Life. http://www.asus.com/us/support/FAQ/1012981/
Please also see the troubleshooting methods provided in a ZenUI app called ASUS Support/Assistance/Battery/Battery drains fast. If still no improvement with battery then we recommend updating the firmware to the latest version. After firmware is applied we recommend performing a hardware reset including wipe cache partition. For hardware reset/wipe cache partition instructions please see the following: http://www.asus.com/us/support/FAQ/1011956/

I have the latest software, I'm waiting for the software fix which you guys need to provide.
I've done everything you suggested, already, nothing is working , its clearly a software bug.
What would make things easier, is if you just admitted there is a software bug, so people who have spent there hard earned money on your product would have some hope that a fix is in the works. Be honest and tell us.
My Asus phone is turned off as of today and in the box, I instead am using an Alcatel Idol 3, which is a joy to use, especially 2days battery life, with no Android OS battery drain!!

Not all Zenfone 2 have this issue. The one I am currently using can last for a few days on standby with firmware WW_2.19.40.22.
There was a new firmware released today WW_2.20.40.58

My ZenFone 2 heated up extremely a week ago while sitting on standby on my night stand. It has drained 75% in 7 hours. Since then the battery life is terrible. I am going to perform a radiotherapy and see if that helps. Most of the day I am using my 2 year old M7 which lasts the whole day with moderate to heavy usage. If the reservoirs not improve things I will contact Asus and see the next course of action. My phone is up to date as far as firmware is concerned.

He is right, though. Battery seems to be a mixed beg for some reason? My phone was fine in .20... Buuut I upgraded it anyways to ParanoidAndroid.

Well, AI brought my phone to work last night and got it back into recovery and wiping status. It took about 45-50 minutes before it shut off. Then I powered it back on which brought it back to wiping. It hung there for a minute and the went to the set up screen. That is the longest I have even seen a phone perform a factory reset. Will go through the setup later. Thanks Frank for your long to how to do this.

I was having really bad battery drain. Flashed CM 12.1 on it and it's been amazing since. Scored 48273 in Antutu and battery is lasting forever. Unplugged at 6am this morning, it's 4pm now, been using it with full brightness all day, I'm a heavy user. 45% still left.

It's a shame that you have to flash different software just to be able to get full use of the phone.
The amount of bloatware that came with this phone is probably the worst I've ever seen!!

[FIXED] Amazing battery discharge

Hello,
Since I updated to MM, lot of things went wrong. Few days ago I got 3-5 hours SoT, and now it is really bad.. this morning it shows 1 hour estimated left and the phone is hot.
Instled GSam, will post screenshots later today.
What's the problem?

did you do a factory reset after updating to MM ?

I have noticed a similar effect on mine, but not so drastic. I used to get over 4hrs+ Screen Time On using Lollipop. Now 3 hours or less. Factory resetting didn't help.

Yes, everything wiped, all reset.. so no old data. MM is not as good as LP :/

Thank you for letting us know. Was thinking of installing MM but I value battery life over everything else.
..Sent from an XDA modified LG G4 on Verizon..

Yeah mate, np.. keep with Lollipop, MM is really worst. I'm using my G4 for about 20 minutes and already lost 10%. Battery life is incredibly low
I'm seriously thinking about downgrading to LP.

I tried going back to LP, but this didn't work for me. I thought I has bricked my G4, but thankfully LG Bridge managed to restore to factory settings.
As well as draining the battery twice as quickly (at least twice as quickly), I can now no longer pair my G4 with my car (so I can take calls by pressing a button on the steering wheel). Bluetooth just keeps crashing on the G4.
I wish I could go back to LP easily. After my last experience trying to install LP KDZ, I'm not confident enough to try it again.

Which tool/method did you use?
On the main MM battery life topic, it seems that the downgrade is successful through LGUP soft.

Am on same boat as you guys. Now, I updated my wifes G3 with MM and the battery time is far better than on Lollipop or on my G4! Go figure[emoji15]

Ok so, I found the okayest fix: if you use custom ROM (like Genisys), flash the stock kernel, it's much butter.
At the moment, no more battery drain/random reboot/overheating . :good:
Seems that SUPEREX kernel is faulty.
https://www.androidfilehost.com/?fid=24269982087005245

I found that the battery is almost 50% on MM compared to LL. From MM i often set the "economy mode" (or what's the name) and turn off wifi and bluetooth wehn I don't use it.
Using it with LG what is almost impossible, the watch drain the battery too much.
Luckili:
1- 20C is out, we have just to whait, I heard that on 20A battery has not that huge battery problem, so maybe they found a bug in the 20B
2-you can carry spare cheap batteries with you, I have always one in my jean poket...

1- I'm going to update to 20c ASAP (downloading right now..)
2- the issue was related to custom kernel SUPEREX integrated in Genisys ROM, flashing stock fixed it
3- I have an extra LG battery + charging cradle and a thin power bank (10000 mAh)

Going from Oreo to Marshmallow & Battery??????

hello there, been following this forum for ages, and a owner of a htc 10 for two weeks....
But I have a big problem....... the battery.....It really is abysmal......
I am currently on LeeDroid oreo, but have tried other roms, and come to the conclusion, the battery sucks!
I know there are kernal tweaks, but with this phone, i just like running the basic custom rom, no bells and whistles......
i am s-off and know how to downgrade/sort signal out/CID/ADB and everything, but I am reluctant to go too far back (Although I do like marshmallow)
I know on other phones, that going back to a previous firmware...sometimes improves the battery
but will it improve my battery????????

I went from Oreo to Nougat. Battery much improved. I was running pure stock rooted. No other mods on Nougat. Took a day to settle, but I could finally leave the house not worrying if I needed to carry a USB cable with me for a charge.

I have this much of a discharge on nougat and on oreo... Did not noticed much of a difference on both FW tbh... As i bought this phone 2nd hand about a month ago, it was already on N and never tested it on MM to tell if there is any difference.
Our luck is the fast charge capability this phone has...

I would say so, yes I had problems. I bought this phone 2nd hand as well. A mint Red one. Pristine condition - at least in appearance. I also have/coming from a daily driver LG V20. Which also uses same 820 chipset. So I had some kind of expectation as to what battery life around. I was kind of shocked how bad the battery was on the 10. Phone was dropping like maybe 20% overnight. In the daytime on stock before I rooted I was getting maybe 1.5 - 2 SOT hours depending on use(i'm not a heavy gamer). I had never experienced such bad battery life before on an HTC phone. I unlocked it/rooted it and started playing with mods. The most success I had was with the Helix engine. I also had some Magisk modules installed to help deep sleep. Probably improved to getting 3 - 3.5 hours SOT. There is a thread dedicated to getting better battery life on Oreo in the guides section and I'd follow that thread and try various things. Also I had done the HTC calibration a few times, and the HTC battery test just to get a sense of the battery's health. In their test, I scored an 85, so I'd say the battery was OK. Not in the area of being a replacement.
But in the end, I was curious to go back to Nougat and then maybe on to Marshmallow to see how battery life would be. Simply going down to Nougat, I was satisfied. Not quite as good as my LG V20, but close enough. Don't feel the need to go down to marshmallow for it.
Maybe in the future I'll go back to Oreo on the 10, but for the most part, Nougat is fine.
From what I've read as well, HTC sort of 'unleashed' the power of the 820 chipset in Nougat, therefore when people went from Marshmallow to Nougat they reported worst battery life but improved performance especially in gaming.

Im aware on the unleashed power htc did on N, but it just don't justify the amount of energy drained. It does not make sense to remove social or other apps from background just because you need to retain battery. Still have a one M7 and the battery still is way better than this htc, with all the apps and settings i need on both, almost a clone of my m7. Im no gamer at all, and don't use whatsup, viber, FB, g+ etc.
You are saying that just by returning from Oero to Nougat, your htc 10 battery got less discharge, like it got fixed? without any mod's?
Thanks for your time to answer me!

Yeah, for me moving back to Nougat fixed my drain problems. Keep in mind, I didn't own the phone before Oreo, so I can't say what it was like pre oreo. But I finally felt comfortable with the performance/battery life I was getting on Nougat. I can't say this will work for you, but others have reported the same. Moving back to Nougat improved battery life.
Before you do it, I'd advise to rule out a hardware problem though to save the aggrivation of downgrading. Do the HTC battery test. If you fall below 70% in the test after an hour, I'd say it might be more hardware related than software.

Good morning.
Wile i was chating with you (yesterday), finally used the htc battery test and to my surprise it went from 99% to 88% in that hour test (99 because it was off and spent that ~1% booting). So, hopefully, will experience the same as the most of you who made the downgrade.
Perhaps its some part on the process of downgrading that fixes something, maybe the format of the [persist] partition one have to wipe to recover access to the baseband (thus the imei) repairs something, a kind of file system error that makes the android system use a lot of power(?).
As i told before, if do mobile repair and to this day, after several hundred of phone fix (hard and software, various brands as lg, samsung, htc,, iDeveices and china phones, never seen this type of problem unless it was hardware problems like pmic (power management IC) due to use of bad chargers / bad cables, water damage, drop damage, etc. Got this 10 and as soon i got here (xda) immediately noticed the amount of people that had the very same problem. And we are (here on xda) just a few to the many thousands of 10 owners around the globe that don't use xda or any other forums to talk about this problem.
Going to do this downgrade today. Im eager to see the result and use my 10 finally (another agnostic hope :angel!!
Thanks!
