[Q] High display % - General Questions and Answers

Hi guys
I have a galaxy s2 and im having problems with the battery. In the battery usage section the most that takes up the energy from the battery is the display. Even lowering the brightness settings the display is still sky high. Now having flashed it few times the warranty has now gone. Tried different roms and still the display on my galaxy is like 45 to 55 percent. Some say its normal some say its not. Once i fully charge the phone within minutes the battery starts getting drained. Seriously what is wrong with it and what can i do to resolve it. Im past my month that i could send the phone back and samsung obviously will find out its been tampered with ie me flashing it
Is there anything i can do to solve the problem with firmware or am i stuck with a faulty phone and just make the most of it till something else comes along?
Any help or ideas will be appreciated

The battery might be dying. How old is the battery? Li-ion batteries will work for 3 years or so only regardless of whether you used it or not.
The display might be taking up so much battery because that's how you use the phone. ie you don't use much of other battery heavy stuff. Make sure you have a low timeout for battery as well.

The display battery usage will be relative to how much screen on time you have. If you are having problems with how long your battery lasts, download BetterBatteryStats (from my sig) and run it for 24 hours or so then check the wake locks to see if any rogue apps are draining your battery.
If you want to return the phone. You can always flash the stock rom and if you buy a USB jig from ebay, you can reset the counter, so Sammy shouldn't know that you have flashed any roms.
For further tips about your battery, why not look at some of the custom rom threads, like Villainrom. They have very good battery stats and there are plenty of tips in the thread.
Hope this helps

well i have it charging at the moment and i am using cognition rom and the phone is like sleeping as we saying. i quickly went into battery usage and display is like 85 %.
Shall i charge it to the max calibrate it then wipe battery stats and let it drain out till its empty fully charge it and then use it till the end of the week and then post a picture of how it went for you guys to see and you give me your ideas on it?
thanks again i really appreciate your opinions

I have never bothered calibrating my Battstats, but it makes some people feel better.
As I said above, the percentage used by display is relative.
If your phone has been on for 24 hours since charge and your display is 85%, then you have a major problem, as your screen on time must be massive.
However if it is 10 minutes since charge and the display is 85% then that probably equates to a few minutes screen on time.
Once you are charged. Run the phone for as long as possible then post screenshots of the Battery Usage (both pages)

Agreed with killall. Battery stats are relative. Say you have used your for ten minutes after charging and the screen was on for 5 minutes or more, an 85% for display is nothing big.
Like he said, see the overall performance of the battery and its life. Display percentage doesn't make that much of a difference if you use your display a lot. I mean if you don't do much CPU intensive gaming or stay connected to wifi and stuff.

Going nuts!! Battery...

Have to charge almost twice a day... I believe it happened after latest 1.45.531.1 update....
Disabled all animation, got auto adjust for display, disabled all what I could.. Still gives me 12 -16 hours on standby only....NOT even using the phone!!!!
Does anyone have something like that??? Or there is some remedy I skipped?
Sorry if I repeat someone's question.
Running full stock, HTC battery.
Thanks in advance!!
Tester.
PS. Recently exchanged the phone.... First one R.I.P......died completely, didn't even charge.
Is there a chance they swapped a refurbished one on me??? How to find out???
can you provide a screenshot of the battery usage graph? also, have you tried getting an aftermarket, bigger battery such as the anker?
I was the same way as you. I checked my battery graph, and standby was using something like 80% of the battery with almost everything turned off. By the time I got home from work I would need to charge it immediately. I bought one of the Anker batteries on Amazon for $15 bucks or so, and I'm now getting about 2 days for a charge. I don't know what it was with my battery, because it sounds like my experience wasn't typical, but I didn't really feel like going through HTC when I could just pay the $15.
I'm with ya...
This phone was running PERFECT prior to the HTC update. Now I'm having a plethora amount of problems, including the battery. For example, prior to the update I would get 13-16 hours on HEAVY usage... Moderate usage? Try a day or day in a half. Now take today for example, I unplugged my phone a little before 7am and I had 20 something percent 4 hours later.
I'm telling you, that HTC update really messed this phone up IMO.
Thanks, guys!!
Will try to get Anker battery, I believe it's 1900 mAh.
But again something running on the background with that update. We'll see.
I'll try to get the graph, maybe someone'll get some sense of it...
Much appreciated,
Tester.
here are the battery stats...
Display..........74%
Cell standby...13%
Phone idle......11%
Voice calls......2%
THAT'S IT!!! Nothing else is running...... SUX...
Still gives 12 - 16 hours of life on almost idle......
I hate to say it,but if you're battery's dying a lot faster after an update,a bigger battery won't help much.
I'd be getting in touch with HTC and ask them what the heck is going on.
Really annoyed with the battery performance. I checked and only display is using 90% of battery. Tried everything to reduce it but no change.

I've had the same issue since the update. My battery drains at a ridiculous rate. I've become really frustrated with the phone since. I rooted it and flashed a custom ROM in hopes of solving the problem but it's the same deal.
I've confirmed it's not the battery either since I've got another one I've tried and only get the same results. Even with Juice Defender running I get nowhere as great a battery life as I did before the update
I'm doing decent 8hrs 20,mins on batt. With 40% left mostly text and internet browsing

Try clicking the graph at the top of the screen it will give you another screen that shows awake/screen time etc. Is your phone going to sleep when you screen turns off?
I was having the same problem and realized that some app was keeping my phone awake even though the screen was off. I uninstalled 80% of the crap I had installed and now my phone sleeps like it should and battery lasts amazingly long time.

How can you tell if your phone is going to sleep when you lock the screen? What is a good method for this? And if I find it its not sleeping when it should, is there a way to find the culprit easily?

Click on the graph in battery stats, it should show awake time and screen on. If your awake time is constant when the screen on time isn't, then chances are you've got an bad app somewhere preventing the phone from sleeping
my battery life was plain **** on 2.3.3., device was running hot all the time (=waste of energy), charging took ridiculous 4h+! When I took it off at the charger around 23:00 the battery was dead at 14:00 the next day with most time being idle!
Since my update to 2.3.4 things got so much better. charging takes around 2h and battery finally lasted a whole day and had 40% juice left in the evening.
Since I got my 2 Ankers+charger for 20$, battery life is crazy now. Been on one charge for 2d2h and still had 16% left. Pushmail on, wifi on (cellular data only when not at home), brigthness at 100%, taking video, pictues and some navigation, messaging and phonecalls. Oh yeah and a few minutes of flashlight use
I would say between slight and medium use.
If 2.3.4 worsened your batterylife, contact HTC or your vendor.
I now replaced the battery at 16% with the other Anker because I still need to do my 5 charge cycles on that one to calibrate it.
Here's an example of the graph. At the bottom you can see awake and screen on time. I pulled phone of charger last night, did some browsing, then ran for an hour with music playing in the background (you can see the small green bar on awake even when screen is off). After I surfed a little and left it off the charger when I went to bed. The phone is properly sleeping when the screen is off and almost 16 hours and still have 62%.
Before I uninstalled the apps, the awake time was solid green across the screen.
Anker battery worked wonders on my device. Before I would have to throw it on the charger after lunch as I like to go for a beer after work and the stock battery would never make it that far... Now when I get home from the bar I still have ~30% battery. Anker battery FTW!
flash a custom rom and u will go gaga over ur battery life. definitely works for me. on standby overnight drain 0-1%.
I found out that if you don't have strong signal at your location your battery drains pretty fast that's why I always connect my phone to WiFi at my apartment where my phone looses signal sometimes. now I lose just 1-2% of power during a night.
Sorry to hear about your battery troubles. A couple days ago I rooted and switched to "Android Revolution HD 3.0.4" and my battery life seems pretty solid. I wasn't having battery life issues prior to this though.
I'm currently in the process of calibrating the battery:
- drain it mostly
- turn off
- plug it in overnight while still off
- in the morning unplug, wait 15 minutes, replug for a few hours; do this ONLY ONCE or you may damage the battery
- power on, immediately go to recovery, advanced, reset battery stats
- start normally
- drain battery until it shuts down; a continuous stress test or stability test app is probably ideal
- once it shuts off, turn it on again to double-check that it's dead; it should only come on for a second or two
- while off, plug in and allow to fully charge; no fooling around with plugging/unplugging, just normal
- calibration complete!
I think you can follow a similar procedure (minus clearing battery stats) to refresh the battery calibration even without rooting/custom recovery. I've read the effectiveness is similar. The phone just needs to be retaught what "full" and "empty" mean, all in one charge cycle. If you calibrate it wrong you could have issues with it shutting off while still reading ~15% battery life.
Anyway, as I said, I'm in the process of doing this. Currently I'm in the "drain it" phase... with my screen at maximum brightness (remaining on), overclocked to 1.5 ghz, I've been running "StabilityTest" (from market) for one hour and fifteen minutes. It stresses both cores as well as the RAM. At this time, my battery is at around 30-40% or so, and it's getting really hot! The phone's temperature is reading as 54.8 degrees!
Also, yesterday I used the GPS for about 4 hours before it died, this was prior to any calibration attempt. I think this is within typical battery life considering that the screen stays on.
TL;DR: Maybe you just need to try a custom rom or recalibrate your battery. Miscalibrated battery can be caused by flashing/updating a rom, I imagine even when it's an OTA. Sense is crippling your phone anyway, you might as well give it a try IMHO.
get yourself an anker battery..I havent charged my phone since the day before and now i have 20% left! heavy usage

Bad Battery? Or just stats?

So this has happened twice now. I'm running on ARHD 4.1.0 w/ Bricked 1.0.
My battery will be running normally, normal drainage, etc., and then it'll just drop from 90 to 70% in less than an hour, and normally drain for another hour or so, and then at around 60% just die. I can't attach a screenshot since normal screenshot apps aren't working and the stock function keeps producing invalid images, otherwise I would, but it literally just looks like it got to 60% and instantly dropped to 0%, there's just a vertical line of missing percentage. I took my phone out of my pocket, expecting it to be around 40 or 50%, and it wouldn't turn on. When I hooked it up to the charger, it took a good 5 or more minutes to even respond to the power button. Do I have a bad battery or just incredibly out of whack battery stats? I have never had this problem with an android phone before, and I thought for sure one full charge overnight would fix it, but I guess not because it happened twice. Any suggestions?
Edit: I use an app called battery snap to monitor the battery level and temperature with a widget, I checked a snapshot history while it was charging and for a few seconds it was at 0.002 volts. But then it jumped back up to 3.897 or something around there. That doesn't sound very good to me.

I don't know much about this, but I don't think battery stats have anything to do while the phone is dead. Even if it does, the phone would at least respond after a minute or two, not 5..
My suggestion is that you can order an Anker battery which is kinda cheap ($15 I think) and try.
You won't loose anything
Edit: Try wiping battery stats, do a full charge, fully discharge and fully recharge again and see if it helps (In your case I don't think this will help, but huh, let's hope ;D)

Thanks, I'll try it. I flashed the new cm7, since I just got tired of sense woes. I read battery life on this was amazing, and I'm hoping it was just a bug with the kernel/rom I was using. Battery stats would've been wiped when I wiped for flashing this ROM, so I'll do a full battery cycle and cross my fingers. My only thought is that maybe, if the battery stats were screwed up enough, it thought it was at 50 or 60% but really it was more like 10%. I remember having issues after I flashed the custom kernel, where before I flashed I was at 70%, and when I rebooted I was at ~10%, and I was like what the hell? So it ended up dying on me, but then I turned it back on and it said 50% or something around there. And then it functioned as normal until it died again, for real that time. Hopefully it was the kernel causing the issue. I'll run a few tests with this and see. If it is the battery, I'll try t-mobile for a warranty replacement of the battery.
The battery measurements seem to be really quirky on this phone. When the phone is idle it seems to drain anything from 50ma to 400ma for no particular reason. You cant really rely on the % too closely
Yeah, I've found the percentages to be pretty inaccurate. Hardly an hour and a half on the battery and it's down to 84%. I did play a game for like 10 minutes and the screen has probably been on for 20 or so, so that's not incredibly unreasonable. I'm just waiting for that dropoff to 0%, if that happens again I'm thinking it's hardware, because I'm running an entirely different ROM and kernel right now.
So it just happened again, went from 42 to 14 after reboot, had to remove battery and reinsert to fix. But other people have reported this issue on cm7. So, I'm thinking maybe that it's an issue with android 2.3.5 or the kernel for it, since it's happened on both arhd 4.1 and cm7, both 2.3.5 roms. I'm going to try and flash faux's cm7 kernel over it and see if it fixes it. May or may not, might be a long shot but worth a shot, I'd rather not switch roms for a third time in the same day.

Faulty Hardware Battery drain?

Hey everyone,
I recently upgraded to android ICS 4.0.4 from 4.0.3 with the hope of the battery issue no longer an issue with my nexus s...
Though my battery drains around 1% every 2-4minutes with normal use, as in just scrolling and going through settings (not using apps), very very light use. I have factory wiped it , I have installed new roms and kernels - mixed and matched, uninstalled apps and installed apps one at a time (to see what drains), I even disabled some the high % wasting applications...
My screen dim is on the lowest, wifi is off, data is off, sync is off, gps is off, screen rotation is off, yet still no improvement, I even fully discharged my battery and re-charged it (while phone is off)- no improvement. And i also changed the CPU settings to 800max and still no improvement.
and when i'm playing a game or something it drops around 10% in ten - fifteen minutes, sometimes drops more.
When my screen is sleeping it takes around 1-2% every 1 hour-2hours, which I think is normal.
My screen is usually 45-50% Battery used by the display and backlight
Android system is usually 15%-20%
Android OS is usually 3%-10%
My battery is only about 4-5 months old, and I've always charge it when its 5-10% left, I don't let it die. I'm going to purchase a new battery to see if the problem occurs, if it does, can it be something with the phone hardware?
But any suggestion on what it is?
I've looked around on forums etc and none of the solutions have worked.
The display is going to use the most. There is no way around it. What are your average use times? If you're only losing a few % an hour idling, that's great! The only things I can think that would help is using black backgrounds whenever possible. You also have to keep in mind you're gaming with your phone and that's CPU intensive, which will cause more drain.

Yeah the display will use the most, but I remember it used to be around 30-35%, I've just been seeing how the battery is lately - just going through settings etc and it goes down every 2-3 minutes by 1%, it used to last much longer than that - 1% every ten mins. Sad thing is - I do use a black background lol to save battery and with games I hardly play them but when I do bye bye battery.
try battery callibration apk from market before you recharge your phone and no use 3g just 2g and make conservative 100/1000 the governor.

I'll try the battery calibration and see how that goes, and change the governor as well to see if any improvement.

Yesterday morning i charged it full 100%. I took it off the charger and left it on the table. It had no wifi or games running at all( at about 8 am) I leave it there all day until about 6 or so. and when i come back its down to 30% WTF IS THAT!. On my dads phone he could have 1% battery and leave it standing by all day and night and he can still turn it on without losing the last percent. Its not an iphone either. Hopefully 4.1 Jelly Bean will have some battery fix for the nexus
BetterBatteryStats. Your best friend when it comes to battery life.
Yeah. Mine isn't bad, but I also just go by my screen usage. If can't get at least 3 hours by the end of the day(which is probably 13 hours), then something is up. Note on calibration, it won't do anything. Those stats are reset once the phone is charged past 90% IIRC. On top of that, our batteries have a different way of reporting the charge. It's not the same as htcs.
Sent by pocket technology
I managed to get my screen down to 40ish% and my Android system is under 10% and I've been timing my battery and noticed every 4minutes exactly it still goes down. I tried calibration does nothing as you said. I'm gonna download betterbatterystats and I have cpu spy running atm...

I have the same issues. 10 hours max not touching the phone at all. Stock, custom, matrix, nothing helps.
Maybe 6 hours if I start using it moderately

Similar issue here. Tried all combinations of ROMs (jb,ics,gb) and kernels (air,marmite,matr1x,lucid) to no avail. Even reverted back to stock GB ROM, radio, and bootloader. Nowhere near 6 hours talk time or 200 hours standby time. I get between 8-10 hours standby time if I'm lucky. I even tried turning the phone off overnight, with a full charge even, and when I went to turn it back on in the morning the battery was dead and I had to plug it in to turn it on.
I picked up a new battery today but the issue seems to persist. I put the new battery in at noon with 98% charge and now 2.5 hours later I'm down to 70%. I am convinced there is a hardware problem that is causing the battery to drain excessively. GSAM Battery Monitor and stock battery stats all look normal with screen using the most battery followed by Android System etc etc. Aside from the battery problem, the phone is awesome and I really don't want to have to buy a GNex when this phone is still salvageable.
So what part of this phone could drain the battery so fast with the screen off? It could be the CPU, GPU, screen digitizer perhaps?
I know you tried with your old battery, but could you try again with the new battery with your phone turned completely off? If there's a drain, then there's definitely a hardware issue.

Phone off for half hour yielded a 9% drop in battery life. I'll keep the responses in this thread only. I just realized every time I respond to a thread it gets bumped to the top of the forum!

Definitely something wrong. I don't lose anything with phone off, so something is messing up hardware wise. Did the phone get water damage?

Battery behaving wierd!!

Hi all, i have SNS just few day old, the wierd problem with it is that no matter what ROM i am on, the battery stays good with consistent discharge pattern till around 30%-35% after that it just nose-dives and goes to zero within 45 min... i have done everything i know like tested different roms, with/without any apps, JB, CM9, ICS, GB, everything behaves same. I also tried to calibrate the battery by 3-4 charge discharge cycles, removed battery stats, but still it persists.
While charging back from 0% it charges rapidly till 30%, much faster than normal, also sometimes if its at 20% and i remove the charger, after 5 min it would show 22%!! i dunno what to do now... Anyone has any idea?
I'm no expert but that does sound like your battery is crap... how long does it last on a full charge? Does it get especially hot or something? I mean if it were a software issue, the power would go somewhere and that's either display or CPU, with a battery drain like that your phone should be glowing and steaming after 45 min.
I hope I helped a bit at least ... Good luck!
Well no, i dont think heat is an issue... even when it dips from 35% to 5% it does not heat up... when charged, during the night too i get 5-6% battery drain which i assume is ok... it lasts around 15-16 hrs till 35% so thats kinda ok i guess but after that it just goes haywire... no clue... i tried to calibrate many times but it just does not get better...

In that case swapping ROMs/kernels won't help. I suggest you get a new battery, but that's just my opinion. A drop like that in such a short time without the device getting hot is definitely not normal
Any one know where can i find a genuine battery who would ship internationally?
But why wont the battery discharge gradually? lets say even if its bad say 1200 1300 mah it should discharge faster than the normal one but atleast at a gradual rate and not suddenly like it does on mine... even after calibration??!!

[Q] Worried about battery, new tablet

I have only used my Galaxy Note tablet a few days, and I am probably using it approximately 5-6 hours tops. It is needing recharged every day! It takes hours to charge and then I only get 5-6 hours usage? Is this normal?
I would appreciate any response.
Thanks.
Galaxy Note 10.1
Try going into setting and then battery see which application is draining the battery and get rid of it.
Note has one of the best batteries around but if you use non stop for heavy application like gamming you should get between 8 - 10 hours of actual usage.
If not then may be there is an issue with your charger or battery get it checked and replaced
Also Note takes a long time to charge around 5 - 6 hours
Hmm.. I use it and get about 8 hours +/- depending what I do with it. I normally use it to take notes for about 5 hours (around 3 hours of actual note taking, 2 hours of doing scratch work for homework on it), and I'm browsing Reddit for the rest of the time. I've noticed that I've had to charge it more often lately, but I've been using it to watch Netflix mostly in the last couple of days.
In my experience with the Asus Transformer, I had to charge almost everyday as well because of my high usage. What do you normally use it for?
A day's heavy usage is normal.
Charge from 0-100% takes about 5 hrs for everyone.
In simple terms, the Note 10.1 has a large capacity
battery that takes a while to charge. Rechargeable
batteries lose their ability to hold charge over time,
but that time is measured in months and years.
I am not sure, maybe I am reading this battery meter wrong. When I go to settings and open battery, it says "51% discharging" and then below that says "15h 12m 59s on battery."
We are mostly using the tab for web surfing, and watched a few Youtube videos. I don't believe anyone has even watched a full show on it yet. It has only been in use since Thursday night. I am not sure what to think.
Doesn't the 51% represent how much battery life is remaining? And what does the other stat (15h 12m 59s on battery) represent?
I appreciate any help or advice.
Also, The only items it shows below that is Screen & Device Idle. Screen says 99% and Device Idle says 2%.
99% usage for screen is quite odd. Maybe try turning brightness down or trying the power saving option for screen. Also, and this may sound silly, but if you haven't rebooted it, that is worth a shot, sometimesthings just drain until rebooted.

To answer your questions
51% is the amount of remaining battery.
15h 12m 59sec is just what it sounds like. It's the time the tablet had been off the charger.
Most of the time your screen should be the highest. Here is what mine looks like. It's been a light day.

Please help me figure out if this kind of usage seems appropriate for battery drain. I am keeping a little log to see how fast it is draining. I just cannot understand if this is normal. Here is a small sample for this evening to see if it seems normal. I only been surfing some, no watching anything.
1109p at 99% battery
1130p at 94% battery
1155p at 90% battery
under settings, battery, all that says is screen 100% no other items listed below
Is it normal to get 5 or 6 hrs then have to recharge even if you are just surfing? I thought people went for days without charging this. I have never owned a tablet before, but I never have to charge my computer or phone this much and I use both for more time than this and not had to recharge this soon.
I am just trying to understand if I have something se tup wrong, or have a faulty tablet.
I truly appreciate all the help from everyone. Thanks.

Have you tried changing the brightness to about 30% (about the same as what I have it on and I get about 3-4 days charge with light usage)? Also rebooting, uninstalling recent apps, enabling/disabling power-saving options?
If nothing else works, try a factory reset and just use it like normal with no extra downloaded apps from google play. Try that for one charge and if it's still bad, there must be something wrong with your unit.
Would you be able to take a screenshot of your battery status window? (hold spen button and hold spen on screen for 2 seconds to take screenshot). It could help us determine the problem. If you could get screenshots of both the main window listing the things that have used battery, as well as the window after you tap the battery graph, that would be great.
Mate, I don't honestly believe you have a problem... I use my tab for around 10hrs/day and I need to recharge it... I do use it for mostly video files...
I also have the 3g version. What's yours? If it's 3g and you are in an area where you don't have a good signal then the modem will be looking and consuming battery power...
Even though this tablet has a large battery, it is usually used up within a day or 2... Try leaving your laptop on all day, it won't last too long either...
That's the main difference between a laptop and a tablet (even if the laptop is in hibernation it will still kill the battery eventually).
