Battery drain caused by 4.2.2 ROM?

Hello, on my Onda v971 tablet running Android 4.2.2, the battery drain is quite obvious (-120%/hour) if you leave the screen and use it moderately (browsing web, youtube, etc.) However, if you leave it idle, it is quite battery friendly (battery usage of about -1.1%/hour). I searched a bit on the web and I hear people saying that it was the ROM that caused the problem. In fact, many people experienced similar issue after upgraded to 4.2.2 no matter what devices they're using. Therefore, I took a snapshot of the battery usage screen and I found that the Screen occupies a great portion in the overall battery consumption. However, on my Note running 4.1.2, I saw that the screen occupies a much less portion in the battery usage. So, here are question that arised;
- Is the battery drain caused by the Android 4.2.2 version of the ROM?
- Is the battery drain caused by the screen?
- The Screen occupies a greater portion in the Battery usage in the case of the tablet than in the case of the Note 2 because a tablet has a bigger screen than the phone or because of it is running Android 4.2.2?
Thanks.

Its obvious I need to change my kernel and ROM now but I can't find a descent 1 lol hopefully the best 1 does not void my warranty thumbs crossed <--- purposely done

Do have the same experience? If so, can you post some screenshot and specified that device you have?

Root/flashing won't void your warranty as long as you are able to keep your binary count = 0.

Better switch back to the old rom (Stock Rom), it happened with me 2.

I am using the stock ROM that comes with it since there are very few or maybe even none of custom ROM for it.
Are you using any kind of custom ROM? Is it base on 4.2.2?

i same problem with 4.3 stock rom on my galaxy s4 , the google services drain my battery =(

Conclusion: using an up to date firmware is not always a good thing. Hope Onda will release a downgraded 4.1.2 firmware to fix the problem...

You are right, there could also be a chance that the battery meter is not correct. But now I am wondering that why it is not correct even that it comes from stock...

Is this normal?

Hey guys I just switched from note 3 to nexus 5. Just want to know if this battery usage is normal? It seems like its dying fast.

You have to provide a little bit more information. Like time on, other usage.

I would say yes, who knows what your screen brightness was at even though I am sure it was probably at auto. Talking on the phone can drain a lot of battery.
Why note 3 to nexus 5, seems odd?

Well you did talk on the phone for a while. But Google Search is draining the battery more than it should. I would just reboot and do another full charge. Google Search was draining my Nexus 7 the other day and the reboot/recharge seemed to have fixed it. For now anyway. Android OS/Google Search seems to be a recurring bug. Unless of course you were using google now a lot, in which case it would probably be normal.

I did not hear of the app until you made that post; the man is probably still stock/non rooted/ just getting used to it.

Look under advanced settings under wifi and see if always scanning is on. If so, turn it off.

I always loved the nexus 4 and when I used the neuxs 5 in person I fell in love with the design and how smooth it was. But the battery is starting to worry me. I'm on cataclysm rom with Franco kernel r22. I have WiFi on with the phone using 3g only. I barely use Google search. The phone calls werent that long either. I just feel like the battery is being drained way to fast for no reason. I keep most apps closed after I'm done using then. I had greenify on and I have the kernel set to 1.7ghz. I just don't know what to do with anymore.

Nexus 5 lagging

Going through some threads it seems most dont experience any lag so im wondering what the problem could be in my case i sometimes notice slight lags when opening/closing app drawer, switching to quick settings, opening/closing apps (turned off animations so not really a problem now) and a few other instances is this normal? it got quite bad so i unrooted it and locked bootloader then unlocked and re-rooted and at the moment i am on stock rom, stock launcher and faux123 stable mainline 11 kernel

Glad I'm not the only one. Do the apps include any of the following: Timely, YouTube?

hopefully it is something that an android update will fix soon as its not just apps for me its everywhere but not all the time, i was wondering if its the custom kernel im using? Hopefully it isn't as i cant change the gamma values in stock kernel so that is the main reason for me flashing a custom one

Doubt it's your kernel. I'm running stock and suffering as well :/ It could also be a defect, some run fine others don't. Same with the same speaker issue, some newer owners especially the red ones claim it sounds better as the old ones.

Try switching to ART runtime, it seems to be much smoother. Im using Franco's kernel with a lot of downgrading in setup and yet I don't experience lags.

I did think about switching to ART but to be honest i dont want to lose anything in terms of stability but hopefully soon it will become part of an update so if lag is normal on dalvik now i dont mind waiting i just wanted to see if its normal or im doing something wrong

I'm sure that the problem could be around some settings with faux kernel. I use it too but recommended settings foe nexus 5 seem to cause some lag for everyone as it's more for saving battery life...
You might nee to play with some settings there Like governor and Hotplug.

Another thing i forgot to mention is when i unrooted/went back to stock i let the apps auto update and straight after i noticed there was lag when opening app drawer so i uninstalled all the updates and it fixed itself has anyone else had this happen?

Installing updates from Play doesn`t make the phone laggy unless there is a problem with an app or some apps. Rebooting after installing updates clears most problems most of the time.

Install BetterBatteryStatts for unusual app behaviour which is most likely the reason of your phone lagging.

Killing apps is it worth it??

I have a bad habit of frequently clearing all apps from my recents
I somewhere read that it's not good (can't remember where)
So is it worth killing apps frequently ?? Does this effect battery life too??
Sent from my Nexus 5 using XDA Premium 4 mobile app

Hi,
I would say you "kill" multitasking...

...which is actually not good, because opening an app that is already in the phones RAM loads much faster plus it doesn't consume that much battery juice

Just leave em. Don't be obsessed with closing stuff all the time
Sent from my Nexus 5 using Tapatalk

Apps running in your multi tasking window still drain some battery. Even Google suggests closing them if you're not using them, to extend battery life.
Launching apps doesn't doesn't spike my current widget readings so I don't think much battery is used there. I've noticed rebooting the phone does cause huge spikes though so try and only do that while plugged in.

This topic has been debated again and again. It makes no tangible difference in battery life. If you want to swipe your apps, go ahead and swipe them. You will never see a difference in battery. And that's because there isn't one.

I notice that if I don't reboot my N5 for a long time, my available RAM goes down to <150mb regardless of what I close. Does it sound like I have a bad app?

no point. the device is more than capable of handling multiple apps open in the background.

Usually its best to just keep pressing the back button repeatedly to exit an app and let it be in the recents. I read that just swiping the app off the Recent doesn't completely exit the app and there's still some background process that will be running for some time.

I noticed an immediate improvement in battery life after turning it off. However, if i found it useful i would have left it on. The device charges so fast that extra battery life hardly matters when I'm not away from a charger all day.

I read around and the drain is present even in the phone with Smart Stay disabled so I don't think that it is the problem.

Battery drain on stand by is IMO kernel issue. Usually stock kernel drains battery much almost with every phone. Same happened with my previous one LG G2, but when I installed custom rom, battery drain stopped and had 100 % battery for many hours (when I am at work and can't use phone much). With S7 (stock rom, no root) when I come to work it is already few % down without doing anything (same app setup as on LG G2) even with always on feature turned off.

milicevic - lg is known for that '' 100% battery problem '' switched from g4 to s7 and i get around 1,2hr more SOT with s7 ( cca 4,5hrs )

From my experience with these 2 models SoT is better on Samsung and Stand by Time on LG. I was just comparing stock and custom rom and LG was no ace at all with stock. But when I was on LG G2 CloudyFa's custom rom based on stock KitKat (later on Lollipop) with his own made kernel, Stand by Time was so great. I really miss that.
