Screen taking up a high amount of battery - Shield Tablet Q&A, Help & Troubleshooting

So after returning my previous model due to issues with battery I'm experiencing some more battery issues. My screen is taking up >60% of the battery through a full battery life. I have auto brightness on. I have color correction preset on sRGB. I'm only getting about 3 1/2 hours screen on time with moderate browsing and gaming. Is this normal? I'm on 4.4.2 if that matters. Just wondering if the Shield just has a mediocre battery or if this is a fixable/defective issue...
Thanks for any help.

Again with the Battery

Is anyone that is having battery issues running Adao Task Manager and Battery Status Pro?
I just factory reset my phone and I got 24hours of batter life. About 8 standby but a good deal of texting, web, some calls and some you tube.
I installed Task Manager and Batter Status Pro last night and my battery this morning went down 15% in about 1hr.
I uninstalled these today and will post again but has anyone else seen big battery drain from these apps or does anyone that is having issues running something similar?
I have been playing with the battery for about a week now.
For me this phone runs pretty good during stand-by. I would have about 2-3% drop for a whole night (7 to 8 hrs), with Google (push), Twitter and weather syncing.
The problem is when you use it, it drops like crazy. When I read news or surf the web, it would drop 1% every 1 or 2 min.
This morning I read an ebook, with black background for about 30 min, it dropped about 3%.
So basically i think the screen, data connection, and non-black background are the ones that kill the battery.
Yea, I agree, the S-AMOLED screen in this thing is an energy hog. OLED's are supposed to be more energy efficient than typical LCD's but I'm just not seeing it. Whenever I look at battery usage stats it shows the display at 70-75% of battery usage. Thats ridiculous. I have until the 18th, but I'm quickly leaning towards returning this and just getting an iphone4. This phone is becoming more and more disappointing the longer I have it.
This morning I have been uplugged 4.75hrs and used 16% no battery monitor and no app killer. Basically done the same things I did yesterday. Some Bebbled,texting, email, phone calls .
I will update tomorrow with total hours battery life for today. Would be happy if I can replicate the 24hours I got the day before installing those apps.
I got like 45 hours of battery with moderate usage during the two days. Seems fine to me, I occasionally used system panel to monitor if anything was using high and constant CPU
This is pretty typical of a 1ghz phone My nexus would last a day of heavy usage, 2 days if i use it lightly. We need to wait for undervolted kernels to be developed xD
Also, it really helps if you disable 3G when you don't use it. This allows me to get 3-4 days of light usage out of my nexus. I haven't played with the Captivate long enough to know how much of a difference this makes on this phone though
when you guys refer to "stand by", what exactly do you mean? Just screen off/phone idle? The battery usage on my phone when I use it seems to be OK even if not amazing, but it continues to sap life from the battery when I'm using it at an alarming rate.
Standby is when the phone is idle/screen off/locked.
The display is definitely power hungry. Using the Power Control widget that comes installed definitely has helped with battery life. It will let you toggle WiFi, BT, GPS, Data Sync, and Brightness (at 3 levels). When I'm not using anyone of those, I turn it off. When I'm indoors, I'll set the brightness to the lowest level. I'm usually at my desk when I'm streaming music, so I'll have it plugged in.

Actually they are more energy efficient on black screens, But screens with a lot of white in them suck battery bad.

This is true the white screens burn the battery etc. I just wanted to let everyone know what I did to make my battery last more that 24hrs.
First, read the Wiki guide and apply some of the battery saving tips.
Second, UNINSTALL a program called "gReader" created by noinnion. This program is a huge battery hog! At least it was for me.
Hope this helps.
Well I guess I am one of the "lucky ones" Im running a live wallpaper and have not run my battery down since the 1st day. Right now Im at 40% life and at 15 Hrs 30m since unplugged. This is with checking facebook, twitter, email, phone calls, internet browsing\video watching and following the steps for the GPS fix. The only thing I have done is install ATK on the phone, besides that its all stock.
One thing I know is a huge battery drain is Time without Service. Check that stat and see if you have anytime at all without service, if so, I am pointing to that as a major drain on the battery. I know currently I have 0% Time without signal, my fiancee however is usually in the 20+% range and her battery drains like many reports I have seen here (she has an EVO).....
Yesterday I only managed 16 hours. Web, Email, A bluetooth file transfer, short bit of gaming. I have about 5% of the cell standby time (26%) without signal. My girlfriend has the Aria which is running Android 2.1 also, has all sorts of widgets, haptic feedback on and can make it at least 24 hours. I get that it has a smaller screen but it is also an LCD. Shouldn't the Super Amoled be saving our battery some display consumption.
i get about 14 hours or so moderate usage and at the end of the day, i have about 35% left at night.
If you detail the "Display" usage in the battery usage details how many minutes has your screen been on? Mine says 1hour 2mins ...this is for 8 hours of running time. My display is using 50% of the battery (which is at 68% now).
W00t W00t today I have reached a new high 2 Days 6 hours and 29 minuts with 12% battery left.....
What I have found is keeping Wifi on while I am at work and home like almost doubled my battery life. Which is great that I can use Wifi all day and not drain the battery so fast like my Fuze. Right now been off charger since 7:30am and I have 84% left. Yesterday after 9 hours I was still over 50%. For me its better than any other smartphone I have owened.
I used manual brightness, (swipe notification bar), turn off GPS/BT. black wallpaper and set Wifi to never sleep. Also the power saving mode in settings is off for other reason and doesn't affect battery.
At 18% right now and it's been off the charger for about 30 hours. I noticed yesterday that while I was connected to wifi at home (with Y5 app), it was draining faster than when I was connected to 3g. Did some tested back and forth and JuicePlotter clearly had a noticeably steeper downward slope for when wifi was connected than when it was using 3g. Weird :\

Terrible Battery life recently

Since i got the phone i have had great battery life, according to gsam my average is like 17.5 hours on battery with like 4.5 hours of screen on.
the last week or 2 though, it has been absolutely terrible. not getting more than like 1.5 hours of screen on, max. i havent changed anything, still keep the brightness around 50% (with auto checked). here are some GSAM screen shots, hopefully someone can help me figure out what is going on.
I left my phone off the charger last night and this was the drain over night.
does anyone have an idea of whats going on, looking at the screen shots? today i was off charger for 4 hours, with 1 hour and 20 min of screen on time (set to dim, like 40% brightness) and it used 60% battery. This battery life is crazy low.
Check for wakelocks.

Galaxy s8+ screen battery percentage is too high

When I bought the S8+ few days ago, the screen percentage was at around 18%. Then it kept going up and now it is at almost 70%. My screen brightness is below 50% and screen timeout is on 30 sec. Anyone knows what's the problem?
As long as the battery is lasting long enough then nothing is wrong. The screen is probably the biggest power user in the phone, except when the CPU is running full throttle. If all you are going is light stuff then the screen usage will be high.
Check how long the screen is on for in the battery stats, if its 5+ hours then its really quite normal.

Battery drain and temp fix

I got XZ3 about several days ago and has been struggling with bad battery life.
I was shocked by its battery life which is way worse than my previous device, XZ1.
But I think I found the cause of it.
As soon as I turned off ambient display feature, the battery life improved dramatically.
I'm still in process of 2nd timing of battery life but so far, with this ambient display off, the battery lasts at least 1.5 times more.

I have it set to Smart Activation and can get a little around 5 hours SoT. With it always on, I got around 4. Might as well try turning it off and seeing if its improved or not.

All these OEM features is known to be battery leechers.
I'm recommending to turn em' off for overall battery life reasons.

battery loss rates

I recently bought a Google pixel that appears to be suffering from excessive battery drain. I'm returning it, but am curious as to what sort of battery life I should expect.
I did an experiment. I fully charged it, and then just used Google camera to record video. I left it on the table, and came back sometime later.
It was losing charge at basically 1% per hour. In the 45 minutes of recording time, it had dropped by 46%. I used better battery stats to validate that no other apps were doing anything significant.
I'm hoping that they replace the battery, and if they do, what sort of life could I expect when taking video?
In general use scenarios, the battery does drain fast. The best I can hope for is 18 hours with less than 3 hours screen time, and sometimes even less...
