Is this normal battery life? - Shield Tablet Q&A, Help & Troubleshooting

hi, today I bough used (one year old, still in warranty) shield k1 and battery drain, even when not playing, is like 1% a minute. Also recharging is pretty slow. I have stock rom noughat version 5.2 and I did factory reset. I found some issues occuring after update to 7.0. But I can't find anything how to fix it. and also I'm not sure if battery can be dead after one year or if it's software related... Please see attached picture
Should I root and try some custom rom? I will stop my warranty

Rooting doesn't void warranty and you can always simply unroot and go to stock ROM, so I suggest you to flash latest stock ROM to get the newest firmware (the one for faster charging) and then you can flash which ever custom ROM you like the most.
Edit : so to answer your question, this is far from a good battery life, but I am 95% sure that with customisation you can make that better. When you do that we can evaluate the health of your battery.

My shield on tesla rom took 6 days to go from 100% to 20% idleing. It took my charger 2 hours to put it back to 100%

High battery drain when not in use T-Mobile NS

I've used a number of roms and kernels since I got the phone a week ago. I let the phone fully charge while off to get to 100% and then I wiped the battery stats in recovery. Proceeded to fully drain the battery to recalibrate. Left the house the phone at the usual 96%. Drove to work and about an hour later the phone was down to 83%. My wakelocks aren't crazy. Probably about a few seconds total. I think the hottest the phone has been was 35°C. It did freeze the other day while trying to do the calibration process. Don't know if that helps any. The battery doesn't look bad. Phone was second hand. I bought an extra battery which should be here soon. Any ideas? Thanks in advance.
Hi,
what android version are you using?
If you're using ICS, go ahead and try the following combinations:
ROM:
AndroidMe (http://forum.xda-developers.com/showthread.php?t=1421564)
Bugless Beast (http://download.peteralfonso.com/crespo/rom)
Kernel
Eugene's kernel Speedy-3 (http://forum.xda-developers.com/showthread.php?t=1401455)
With this combination I'm getting at least a day battery.
Sorry for the late reply. I'll give this a go. I've been running 2.3 for a while and was actually looking for an ICS rom to try out.
Try disabling auto-rotation in Settings > Display
It is said to be the cause of battery drain in stock ICS.

Nexus 5 is coming to me..i need some advice!

Hi guys!
In the next days the Nexus should be arrive also to me and i have a few doubts about the modding! Then i'm not new to Android modding...i have a LG Optimus 3D and i modded it in every possible ways (change bootloader or baseband, flash custom roms, root etc).
I read a lot of guides about Nexus 5's modding and i think that the modding is not hard!
However i want when i will put out the phone of his box i want only to turn on to see if it works fine and then if the battery is equal or above 60 % i want to unlock the bootloader as soon as i can and then recovery, root(with SuperSU.zip or with a stock rom pre rooted) and franco's kernel!
Then i know that flash things and also unlock bootloader can affect the battery percentage...however my main question is if i will make these things immediately after i put out of the box this can affect in some ways the battery's life? I mean...after the battery will discharge for the first time i need to put the phone on charging for 12 hours? (and then after this 12 hours i can mod my phone?)...i'm really confused about battery because i read a lot of things...someone told that with modern batteries the 12 hours is not necessary someone told that is necessary...
Thanks in advance!
There are a lot of different opinions about extending the life of your battery with proper charging habits (including the first charge)...I've read lots of conflicting information too. But honestly, I don't think it's worth stressing over. If you don't charge it "correctly" the first time, any long term reduction in battery life is going to be very minimal.
The average life span of phones these days is about 2 years for most people, and I doubt you would notice a significant difference within that time anyway (barring any defects). Batteries are built to last much longer than that.
My phone arrived with a 90% charge, so I proceeded to unlock, root, etc. right out of the box like just you're planning to, then charged it afterward (don't remember what percent it was at). No problems here, so you should be fine to do the same.

It won't mess the battery. When I got mine I unlocked the boot loader installed a custom recovery, and made a nandroid. Then I played with it on stock to make sure everything worked. I would recommend that
Thanks to all! Some time ago i bought an extended battery for my Optimus 3D by Mugen...and in the start guide they told the the first charge needed 12-14 Hours and then you can charge the battery every time you want! However i wish that my Nexus 5 will have a good percentage and i can unlock the bootloader, after i will put root or a rom stock prerooted and then the franco's kernel! I want to keep my phone stock because for other functions i will installa Xposed! Thanks for the help guys! Oh and if you have any other advice it will be appreciated!

Latest Software still causing battery drain?

I have read on various forums that the latest software update has been causing problematic battery drain on the M8 and more often the Verizon version. I briefly had one about a month ago but had to return it due to some contract issues. Now I am looking to get another as I really liked it. I did however notice that the battery did drain pretty fast when I had mine. It had the latest 4.4.2 software on it. If I root it, can I install an older ROM and have the great battery life return? Are there any tips on what was causing the issue? I see AT&T actually pulled the Kitkat update due to battery issues several months ago.
Thanks for the info,
Rob
No battery drain on my device. I'm on all stock Verizon and I did a factory reset after the 4.4.4 update. Battery life is excellent and I get through a 24 hr work shift with about 20 percent battery left, about 3 hrs SOT. I'm sure you can get an older ROM version by asking in the thread of the ROM you choose if it isn't available in the OP. Many fine folks here keep old copies. Good luck buddy!

Thanks I appreciate the reply.
The oldest ROM it originally came with is 4.4.2 so I don't know how much that would help your case. Maybe the newest 4.4.4 can help if you still have problems on 4.4.2 on your new phone (if it isn't 4.4.4 already)
I've had the phone since release date and never had a battery drain issue. The battery life was great at launch and has gotten a bit better with firmware releases.
Before I had the M8 I had a Gnex. On that Gnex android 4.4.4 would cause the phone to get very warm and increased battery drain. It doesn't surprise me that it does it on the M8 as well.
I didn't see any battery drain on 4.4.2, 4.4.3, or 4.4.4.
Pfft with all the ROMs out and kernels to help who needs battery drain.
HTC One M8
After the update, my battery life dropped by an honest 50%.
I dont use my phone much and used to get 6 days on a charge, now I only get 3.
I realize that's more than most and I should not complain, but still.
I also had to reset my phone due to problems with pictures in my previously recieved texts not opening.
The reset obviously did not help my battery problem.

6 days per charge? Haha what?

It's true, I'm older & only use a phone to make calls, & a few texts.
No social media stuff or anything like that, all Forum stuff is done on a tablet or computer.

Insane battery drain despite different roms

I've tried stock 5.2 and different roms. Even in TWRP I find the battery is draining insanely quick. I charged it up to 100% and when I went into TWRP, wiped everything and installed Lineage OS and gapps, it dropped about 5%. At this point I'm not sure if the battery is just basically on its last legs from being on 5.3 for so long. Does anyone have any suggestions? Something else I can try flashing to see if it fixes the insane battery drain? I'm considering just selling the thing off and buying something else, but would want to try and salvage this thing if I can.

Flashing a ROM and starting it up (and installing apps) uses a lot of processor power, and therefore a lot of battery. A 5% drop flashing a ROM and starting it the first time would be completely expected. After flashing a new ROM I would recommend you use it for a day or so(drain battery to almost empty) and recharge; to let the ROM "settle in" and the battery meter to calibrate. Do this before passing any judgment on battery.
Severe battery drain has been a consistent issue on all stock Nougat builds. But I can't speak for Lineage, as I only run stock ROM (rooted). But it's an OS issue, not a battery issue. The worst case, if downgrade to Marshmallow, and it should fix the battery drain.

Battery life

Hey,
I get second hand g930fd few weeks ago. I expected a better battery performance but it's horrible. I replaced the battery with an original one and again no improvement.
Can You suggest a solution?
I can't believe, that the 3000mah can't survive all day on average to high usage.
Currently on rooted Oreo stock rom.
Thanks in advance,

Gaming eats battery very quick
Not gaining at all. I am making around 2.5-3 hrs. SOT with one discharge.

Same here. Latest Oreo firmware and terrible battery life (it was the same before with marshmallow). I noticed that Android system is above screen in battery usage. That's not good. Something on Android is draining the battery. No idea what. I have a g930a running a g930u ROM for xaa (no company).

Have you tried re-aligning the dylithium matrix in the warp core?
I jest. But seriously every update adds more bloatware and system demands on the battery. Samsung is nudging you toward its latest phone the Sammy 10 but since there's no real need for us to pay a Kings ransom for their latest flagship every 12 months they need to up the game a little and this is how they do it.
They don't want customers holding onto old phones, no they want you to be impressed with a new camera or button or super-duper screen or something as equally unimpressive.
Custom ROM is they way to go and drastic de-bloats of stock firmware. Be ruthless, if you don't use it, get rid or disable.
Tried a full stock firmware flash with Odin? Assuming selling it second hand all they did was factory reset via settings or recovery, which isn't as clean as a full odin flash.
So any suggestion? Did the batterystat reset, let's see if it's work.
Probably downgrade to Android 7?
